The Issue The central issue in this case is whether the permit to construct a Cyclonaire Docksider pneumatic unloading system, permit no. AC 56-157174, which was requested by Florida Sun Cement Company, Inc., should be approved.
Findings Of Fact Based upon the testimony of the witnesses and the documentary evidence received at the hearing, I make the following findings of fact: Florida Sun is a Florida corporation whose address is 4550 Glades Cutoff Road, Fort Pierce, St. Lucie County, Florida 34949. Tuxedo is a Florida corporation whose address is 1110 North Second Street, Fort Pierce, Florida 34950. The City is an incorporated municipality with a boundary located approximately one and one-half miles north of the Tuxedo packing house. On November 15, 1984, the Department issued permit number AC-56-86471 to Roger Charles, President of Manatee Cement Co., Inc. This permit authorized the construction of a cement bulk terminal/ship unloading facility which would include two 10,000 metric ton silos for the storage of Portland cement which would be vented by one common baghouse. The location for the facility was to be at Port Avenue and Harbor Street in Fort Pierce, Florida. This location is directly across the street from the Tuxedo packing house. On November 15, 1984, the Department issued permit number AC-56-873l0 to Roger Charles, President of Manatee Cement Co., Inc. This permit authorized the construction of a cement Co., Inc. This permit authorized the construction of a cement bulk terminal/truck loading and packhouse which would include one 240 ton storage bin vented to one baghouse, two truck loading spouts vented to two baghouses, and one packing facility which would also be vented. On November 25, 1985, the Department extended the expiration dates for the permits identified in paragraphs 4 and 5 until November 15, 1989. Later, on August 11, 1987, the Department transferred the permits to Roger Charles, president of Florida Sun. On November 14, 1988, Florida Sun filed an application for a barge- mounted pneumatic Portland Cement unloader. This unloader, a Cyclonaire Docksider, was proposed to be used in connection with the facilities previously permitted. Florida Sun sought to utilize the pneumatic unloader to extract cement from the holds of ships moored at the Fort Pierce port which is adjacent to the mainside silo facility. From the dock area the cement would then be conveyed through a sealed pipeline to the storage silos. From the silos, the cement would be loaded into trucks and transported away from the site. Under the 1984 permits' proposal, Florida Sun intended to unload the cement via self-unloading ships which did not require a permit. The 1988 request for the barge-mounted unloader would allow more types of ships to unload at the facility. On February 7, 1989, the Department issued an Intent to Issue which announced its intent to issue the permit. On February 12, 1989, the notice of the Intent to Issue was published in the News Tribune, a newspaper published at Fort Pierce, St. Lucie County, Florida. Tuxedo and the City timely filed petitions challenging the proposed permit. Neither petitioner had timely challenged the permits which had been issued in 1984. The pneumatic unloader which is the subject of the permit request is to be manufactured by Cyclonaire Bulk Cargo Systems, Inc. (Cyclonaire). The Cyclonaire Docksider unit will be attached to a free-floating barge which will be secured to the dock. The barge will be capable of movement in an east-west direction to allow access to each opening of the ship's hold. The Cyclonaire Docksider operates by extending an arm into the hold of the ship. The arm is equipped with a pneumatic device which extracts the cement from the ship and conveys it through a pipeline. The Cyclonaire utilizes two diesel engines which operate the extraction and conveying portions of the device. The Cyclonaire is vented through filter cartridges manufactured by W.L. Gore and Associates. Cyclonaire has executed a warranty for the Docksider pneumatic unloading system which provides, in pertinent part: Not more than .02 grains of particulate matter shall be contained in each dry standard cubic foot of air discharged into the atmosphere from the vacuum pump exhaust ports during normal operation of ice system, as measured using the applicable test methods specified by the State of Florida Department of Environmental Regulation. The opacity of emissions measured across the vacuum pump exhaust ports during normal operation shall not exceed 5o/o when measured using the applicable test method specified by the State of Florida Department of Environmental Regulation. The opacity of emissions measured across the top of the hold of the vessel being discharged by the DOCKSIDER system shall not exceed 5o/o during normal operation of the system, when measured using the applicable test method specified by the State of Florida Department of Environmental Regulation. There shall be no leaks or fugitive emissions from the unloader suction line(s), from the filter vessel, from the cement receivers, from the cement discharge line(s), from the supply line(s) to the vacuum pump, or from the vacuum pump itself. Cyclonaire has also executed a warranty for the conveying lines to the silos which provides, in pertinent part: Not more than .02 grains of particulate matter shall be contained in each dry standard cubic foot of air discharged into the atmosphere from the vacuum pump exhaust ports of the system during normal operation of the system, as measured using the applicable test methods specified by the State of Florida Department of Environmental Regulation. The opacity of emissions measured across the vacuum pump exhaust ports during normal operation shall not exceed 5o/o when measured using the applicable test method specified by the State of Florida Department of Environmental Regulation. The opacity of emissions measured across the top of the hold of the vessel being discharged by the Docksider system shall net exceed 5o/o during normal operation of the system, when measured using the applicable test method specified by the State of Florida Department of Environmental Regulation. Not more than 0.02 grains of particulate matter shall be contained in each actual cubic foot of air discharged by the baghouse at the silos per performance warranties of the Fuller Company as measured using applicable test methods specified by the State of Florida DER. The opacity of emissions measured across the baghouse exhaust shall not exceed 5o/o when measured using the applicable test method specified by the State of Florida DER. There shall be no leaks or fugitive emissions from the unloader suction line(s), from the filter vessel, from the cement receivers, from the cement discharge line(s), from the supply line(s) to the vacuum pump, or from the vacuum pump itself. This warranty does not apply to situations which result due to factors beyond the reasonable control of Seller, e.g., equipment malfunctions, improper maintenance, improper operations or wind gusts in excess of 35 miles per hour. A system similar to the proposed Florida Sun Cyclonaire Docksider is located in Tampa, Florida. When tested, the Tampa unloading system resulted in an average particulate concentration of .0043 gr/dscf and the average particulate emission rate was .21 lb/hr at an average cement unloading rate of 236 tons per hour. The visible emissions were found to be less than 5 percent opacity. Florida Sun proposes to vent emission sources by use of baghouses. These filtering systems vent dust-laden air by extracting the particles which fall, by gravity, while the air is released through a filter to the outside. The filters are cleaned by a jet of air which is pulsed on the outside of the filter unit. The Florida Sun facility will have baghouses to vent the silos and the truck loadout spouts. The Fuller Company manufactures retractable loading spouts which will convey the cement from the storage silos to the transporting trucks. The truck loading process will take place within an enclosed silo. The truck will be positioned under the spout and a cone will be extended down into an opening on the top of the vehicle. Proper operation requires the spout to connect to the truck so that particles are not released into the air. The spout allows the cement to flow into the truck while air is displaced back into a venting system. Each loading spout will have its own venting system. The Fuller Company performance warranties provide, in pertinent part: Fuller Company warrants, when the equipment covered by this agreement, is adjusted and operates at the design operating conditions, as specified within the specifications, and as enumerated in Section A hereafter; that the maximum solid particulate emissions exiting the baghouse will not exceed 0.02 Gr/ACF excluding condensibles. The potential sources of air pollutant emissions associated with the Florida Sun cement facility are as follows: unconfined and unquantifiable particulate matter emitted from the hold of the ship during the unloading process; the emissions from the Cyclonaire unit (the venting required to separate the dust-laden air in order to pass the cement into the conveyor line); emissions from two diesel engines which generate energy for the extraction and conveying unit; the baghouse which vents the silos as they are being loaded; the truck spout venting units; and the unconfined but quantifiable particulate matter generated by truck traffic. The total of the quantifiable emissions for the Florida Sun facility will be 19 tons per year. The Florida Sun facility will not contain the 240 ton cement storage bin authorized by the 1984 permits. Based upon Florida Sun's stipulation to that effect, potential emissions from that source have not been considered. The Florida Sun facility will not contain the packhouse authorized by the 1984 permits. Based upon Florida Sun's stipulation to that effect, potential emissions from that source have not been considered. The stipulated Florida Sun annual throughput of cement for this facility will be 279,000 tons per year, plus or minus 10 percent. In addition to the equipment to be utilized to limit the expected emissions, Florida Sun intends to pave or grass its entire facility. Regular maintenance of this area will provide reasonable precautions that unconfined particulate matter will not be released into the atmosphere. Further, training of personnel will aid in the proper operation and maintenance of the equipment. Operation of the Cyclonaire should not occur during wind conditions exceeding 35 miles per hour. While helpful to determine air quality impacts, air quality modeling is not required by rule for permit approval for minor projects with a non-toxic source. To be helpful, an air quality model must be based upon assumptions of fact likely to occur. All parties utilized the Industrial Source Complex Short- Term model. That model is an EPA approved model for general air quality analysis. In this case, the model submitted by Tuxedo and the City contained numerous emission factor errors which rendered their model's results unreliable. Among the errors were: the assumption that the truck loading activities would occur twenty-four hours a day, 365 days a year; the by Tuxedo and the City contained numerous emission factor errors which rendered their model's results unreliable. Among the errors were: the assumption that the truck loading activities would occur twenty-four hours a day, 365 days a year; the assumption that the truck loading activities would result in a spillage of cement material at a rate of 1.2 grams per second for twenty-fours a day, 365 days a year; and the assumption that truck loading would occur outside of the enclosed silos. The air quality models run by Dr. Koogler and Mr. Rogers corroborated the other forms of assurances given by Florida Sun. The Tuxedo packing house is located directly across the street to the north from the Florida Sun facility. There is also another citrus packing house located directly across the street to the south from the Florida Sun property. The Tuxedo packing house boxes a variety of fresh citrus fruits for the fresh market. Citrus fruit is sensitive to skin abrasion which can result in a premature decay of the fruit and limited shelf-life of the fruit. As a result, prudent packers take every precaution to avoid abrasive particles from coming in contact with fresh fruit. Cement is an abrasive material. The Tuxedo packing house is ventilated by large doors located around the building and an opening at the top of the structure. In general, Tuxedo is located downwind from the Florida Sun facility.
Recommendation Based on the foregoing, it is RECOMMENDED: That the Department of Environmental Regulation enter a final order approving the application for permit no. AC 56-157174 with special conditions to include the prohibition of loading via the Cyclonaire Docksider during wind speeds in excess of 35 miles per hour, proper and routine inspection and maintenance of the equipment to assure it is operated in accordance with the manufacturers' directives, and training for operators of the Cyclonaire to assure compliance with manufacturer's guidelines equipment to assure it is operated in accordance with the manufacturers' directives, and training for operators of the Cyclonaire to assure compliance with manufacturer's guidelines. DONE and ENTERED this 4th day of October, 1989, in Tallahassee, Leon County, Florida. JOYOUS D. PARRISH Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32301 (904)488-9675 Filed with the Clerk of the Division of Administrative Hearings this 4th day of October, 1989. APPENDIX TO CASE NOS. 89-1121 AND 89-1271 RULINGS ON THE PROPOSED FINDINGS OF FACT SUBMITTED BY TUXEDO: Paragraphs 1 through 19 are accepted. Paragraph 20 is rejected as contrary to the weight of the evidence; during normal and proper operation of the truck loading spouts, spillage should not occur. Incidents of spillage would suggest a violation of the permit conditions and require immediate correction. Paragraph 21 is rejected as comment or irrelevant. It is accepted the loading spouts have a tolerance of approximately one-half inch; the balance of paragraph 22 is rejected as irrelevant, embellished comment, or argument. The first four sentences of paragraph 23 are accepted; the balance is rejected as comment, recitation of testimony, irrelevant, or argument. Paragraph 24 is accepted. With regard to paragraphs 25 and 26, it is accepted that Dr. Koogler visited the Tampa Cyclonaire facility on two occasions, that the winds on the first visit were approximately 2-5 miles per hour, that on the first visit he observed no visible emissions, that on the second visit the winds were 5-10 miles per hour, and that on the second visit he observed visible emissions while a front-end loader scraped the cement off the bottom of the hold to the center for the Cyclonaire to extract it; otherwise, the paragraphs are rejected as comment, argument, embellishment on fact, or irrelevant. Paragraph 27 is accepted. Paragraphs 28 and 29 are accepted. Paragraph 30 is rejected as contrary to the weight of the credible evidence. While the barge will be free-floating and capable of being located along side the hold to be unloaded, the barge will not be in motion during unloading, no assumption to the contrary has been made. Paragraph 31 is rejected as contrary to the weight of the evidence. Paragraph 32 is accepted. Paragraph 33 is rejected as repetitive, comment, unnecessary. See 7 above. Paragraphs 34 and 35 are accepted. With regard to paragraph 36, it is accepted that Dr. Koogler and Mr. Yocum used the same emission factors for the four sources identified and listed in the paragraph; otherwise, the paragraph is rejected as comment or irrelevant. It is accepted that Mr. Yocum utilized the AP-42 to compute the emission factors used for the diesel engines; otherwise the paragraph is rejected as irrelevant. It is accepted that Dr. Koogler utilized data from the diesel engine manufacturer to compute the emission factors he used; otherwise the paragraph is rejected as irrelevant. Paragraph 39 is rejected as irrelevant, immaterial, argument, or comment. Paragraph 40 is rejected as irrelevant, immaterial, argument, or comment. Paragraph 41 is rejected as contrary to the weight of the evidence. That individuals attempted to quantify the fugitive emissions from the hold does not render such attempts reliable for purposes of determining air quality impact. Such "best guesses" are only estimates which, in this case, do not suggest the project should not be permitted. Paragraph 42 is rejected as contrary to the weight of the evidence. Paragraph 43 is rejected as unsupported by the weight of the evidence to the extent that it suggests such occurrences would be under normal and proper operating conditions. Incidents of such operation would be a violation of the permit terms. With regard to paragraph 44, it is accepted that the spout's ability to collect the cement dust and route it up to the baghouse is not warranted; however, it should be noted that during that function the truck loading will take place within an enclosed silo. With that clarification, the paragraph may be accepted. Paragraph 45 is rejected as irrelevant; spillage is not anticipated under normal and proper operating conditions. Further, truck loading occurs within an enclosed silo. Paragraph 46 is rejected as a recitation of testimony/ Paragraph 47 is rejected as repetitive (see p. finding 15). Paragraph 48 is accepted to the extent that it recites Mr. Yocum's process for computing an emission factor; that factor, however, is rejected as unreliable and contrary to the weight of the evidence. Paragraph 49 is accepted but is irrelevant to the resolution of the issues of this case. With regard to paragraph 50, it is accepted that all parties attempted to model sources in connection with this application; otherwise, the paragraph is rejected as argument, comment, or irrelevant. Paragraph 51 is accepted. Paragraph 52 is rejected as irrelevant. Paragraph 53 is rejected as recitation of testimony, comment, or irrelevant. Paragraph 54 is rejected as irrelevant. Paragraph 55 is rejected as irrelevant. Paragraph 56 is rejected as argument, comment, or irrelevant. Paragraphs 57 and 58 are rejected as contrary to the weight of the evidence. Footnote 5 of paragraph 59 is accepted; the balance is rejected as irrelevant or contrary to the evidence. Paragraph 60 is accepted. Paragraph 61 is rejected as argument, comment or irrelevant. Paragraph 62 is rejected as irrelevant. Paragraph 63 is rejected as irrelevant. Paragraph 64 is rejected as irrelevant. Paragraph 65 is rejected as irrelevant. When modeling is required, paragraph 66 is accepted as the proper standard; otherwise, rejected as irrelevant. Paragraphs 67 through 69 are rejected as irrelevant. Paragraph 70 is accepted. Paragraph 71 is accepted. With the clarification that there would also be receptors with lower concentrations, paragraph 72 is accepted. Paragraphs 73 through 75 are rejected as irrelevant or contrary to the weight of the evidence. Paragraph 76 is rejected as argument, comment, or irrelevant. Paragraph 77 is rejected as irrelevant. Paragraphs 78 through 80 are rejected as contrary to the weight of the evidence or irrelevant. Paragraph 81 is accepted. Paragraphs 82 through 83 are accepted. Paragraphs 84 through 92 are rejected. The paragraphs accurately recite what Hoffnagle did; however, the facts proffered are rejected as contrary to the weight of the credible evidence, irrelevant, or unsupported by the record. Paragraphs 93 through 98 are accepted. Paragraph 99 is rejected as irrelevant. Paragraphs 100 through 106 are accepted. With the deletion of the word "strikingly" paragraph 107 is accepted. Paragraphs 108 through 115 are accepted. Paragraphs 116 through 118 are rejected as irrelevant. RULINGS ON THE PROPOSED FINDINGS OF FACT SUBMITTED BY THE CITY: Paragraphs 1 through 6 are accepted. With regard to paragraph 7, the throughput stipulated to was 279,000 tons per year plus or minus 10 percent; otherwise, paragraph 7 is accepted. See comment p. 2 above, paragraph 8 accepted. Paragraphs 9 and 10 are accepted. With the substitution of the phrase "may be" for the word usually," paragraph 11 is accepted. There is no evidence as to whether Florida Sun will use such a system or not. With the deletion of the word "only" paragraph 12 is accepted. Paragraphs 13 through 21 are accepted. Paragraph 22 is accepted; however, there is no evidence which suggests the plant will, in fact, be operated 24 hours a day, seven days a week, 365 days a year. Further, the throughput limitation would suggest to the contrary. Paragraphs 23 through 31 are accepted. Paragraph 32 when clarified to include that emissions are sometimes less than the average, is accepted. Paragraph 33 is accepted. Paragraph 34 is rejected to the extent that it suggests Mr. Yocum's emission rate should be accepted as fact of this case. While the paragraph accurately states what Mr. Yocum did, his factor is rejected as unreliable or contrary to the weight of the evidence. Paragraph 35 is accepted. Paragraph 36 is rejected as irrelevant. Paragraph 37 is accepted. Paragraph 38 is rejected as irrelevant; that parties attempted to model the hold emissions does not render the results reliable, such "best guesses" may be noble but have not formed the basis for a finding of fact. Paragraph 39 is rejected as irrelevant. Paragraphs 40 through 43 are rejected as irrelevant, see comment in P. 16 above. Further, such fugitive emissions are unquantifiable under the present methodology. Paragraph 44 is accepted. Paragraph 45 is rejected as irrelevant. Paragraph 46 is accepted. With regard to paragraph 47, it is accepted Dr. Koogler and Mr. Yocum used the same emission factor for the silo baghouse/ Paragraph 48 is accepted. With regard to paragraph 49, it is accepted Dr. Koogler and Mr. Yocum used the same emission factor for the truck spout filters. With regard to paragraph 50, it is accepted that the doors to the silos will be closed during truck loading. In their models, both Dr. Koogler and Mr. Yocum assumed otherwise. Consequently, both may have obtained an inflated result. Paragraphs 51 and 52 are accepted. To the extent that paragraph 53 suggests spillage may result from improper operation, such paragraph is rejected as irrelevant. Under normal and proper operating conditions, spillage would not occur. If so, it would be a violation of the permit. Paragraph 54 is accepted. With regard to paragraph 55, see comment p. 27 above; consequently, the paragraph is rejected as irrelevant. Paragraph 56 is rejected as contrary to the weight of the evidence. Paragraph 57 is rejected as irrelevant and erroneous (math error). The number of trucks per year is limited to the throughput cap; the number which might be filled during a 24 hour period would depend on the factual circumstances at the time (whether the silos were full, etc.). Paragraphs 58 through 62 are accepted. Paragraph 63 is rejected as contrary to the weight of the evidence. While the paragraph correctly states what Mr. Yocum did, no confidence has been given his analysis. To the extent that Dr. Koogler attempted to tie the daily truck rate to the annual throughput cap, paragraph 64 is accepted; however, for the reasons set forth in p. 31 it is irrelevant. Paragraphs 65 through 68 are accepted but are unnecessary. Paragraph 69 is accepted to the extent that it recites Mr. Yocum's finding but is unnecessary and irrelevant. Mr. Yocum's emission factors are unreliable based upon the weight of the evidence in this case. Consequently, little value has been placed on the model results which were based on his factors. Paragraph 70 is rejected as argument, irrelevant, or contrary to the weight of the evidence. The last two sentences of paragraph 71 are accepted. The first sentence is rejected as rejected as speculative, irrelevant, or contrary to the weight of the evidence. The factual matters addressed in paragraphs 72 through 75 are accepted to the extent addressed in my findings of fact; otherwise, the paragraphs are rejected as comment or recitation of testimony. Paragraphs 76 and 77 are accepted. With the deletion of the word "much," paragraph 78 is accepted. With the deletion of the "s" on the word "meter" (used two times), paragraph 79 is accepted. Paragraph 80 is accepted. Paragraph 81 is rejected as argument or comment. There might also be receptor locations with smaller concentrations. Paragraph 82 is rejected as irrelevant. Paragraph 83 is rejected as irrelevant. Paragraph 84 is rejected as irrelevant. Paragraph 85 is accepted but is irrelevant. Paragraph 86 through 89 are rejected as irrelevant. Paragraph 90 is accepted. Paragraphs 91 through 96 are rejected as irrelevant or contrary to the weight of the evidence. Paragraphs 97 and 98 are accepted. Paragraphs 99 and 100 are rejected as irrelevant. Paragraph 101 is rejected as irrelevant. Paragraphs 102 through 105 are accepted. Paragraph 106 is rejected as irrelevant. RULINGS ON THE PROPOSED FINDINGS OF FACT, SUBMITTED BY FLORIDA SUN: To the extent addressed in findings of fact paragraphs 4 and 5, paragraph 1 is accepted otherwise rejected as irrelevant. Paragraphs 2 through 4 are accepted. Paragraph 5 is accepted to the extent in findings of fact paragraphs 20 and 21; otherwise, rejected as irrelevant or unsupported by the record. The first sentence of paragraph 6 is accepted. With regard to the balance of the paragraph it is rejected as irrelevant except to the annual throughput being 279,000 tons plus or minus 10 percent. Paragraphs 7 through 12 are accepted. Paragraph 13 is rejected as argument or conclusion of law. Paragraphs 14 through 23 are accepted. The second sentence of paragraph 24 is rejected as unsupported by the record. The balance of the paragraph is accepted. Paragraphs 25 and 26 are accepted. With the exclusion of the last phrase of the paragraph (which rated the opacity of the emissions on Koogler's second visit), paragraph 27 is accepted. Paragraphs 28 through 34 are accepted. To the extent that Dr. Koogler and Mr. Yocum used the same emission factors for the Docksider silo, and spouts, paragraph 35 is accepted. Otherwise, the paragraph is rejected as argumentative, comment, or irrelevant. The basis for determining the unreliability of Mr. Yocum's factors is addressed. The first sentence of paragraph 36 is accepted. The balance is rejected as irrelevant or argument. Paragraph 37 is accepted. To the extent that a facility which emits less than 100 tons per year is defined to a minor facility, paragraph 38 is accepted. Otherwise, is rejected as argument, comment, or irrelevant. Paragraphs 39 through the first sentence of paragraph 40 are accepted. The balance of paragraph 40 is rejected as irrelevant. Paragraphs 41 through 43 are accepted. Paragraph 44 is rejected as irrelevant. Paragraph 45 is rejected as recitation of testimony. The first sentence of paragraph 46 is rejected as contrary to the weight of the evidence. The balance of the paragraph is accepted. Paragraphs 47 and 48 are accepted. Paragraphs 49 and 50 are accepted but are irrelevant, immaterial or unnecessary. Paragraph 51 is rejected as argument. Paragraph 52 is accepted to the extent that it states this facility is a minor facility located in an attainment area; otherwise, rejected as irrelevant, immaterial, or argument. Paragraph 53 is accepted. Paragraphs 54 through 56 are rejected as irrelevant. Paragraph 57 is accepted. Paragraph 58 is accepted. Paragraph 59 is rejected as repetitive. Paragraph 60 is accepted. Paragraphs 61 and 62 are accepted. Paragraph 63 is rejected as irrelevant or unsupported by the record. Paragraph 64 is rejected as irrelevant or unsupported by the record. Paragraph 65 is accepted. The first three sentences of paragraph 66 are accepted; the balance is rejected as contrary to the weight of the evidence.

RULINGS ON THE PROPOSED FINDINGS OF FACT SUBMITTED BY THE DEPARTMENT: Paragraphs 1 through 21 were accepted. Paragraph 22 is rejected as argument. Paragraphs 23 through the first sentence of paragraph 26 are accepted; the balance of paragraph 26 is rejected as argument, comment or irrelevant. Paragraph 27 is rejected as irrelevant. Paragraph 28 is rejected as irrelevant. Paragraphs 29 through 31 are accepted; however, it should be noted that modeling was not required, by rule in this case, and further, that the modeling performed by Mr. Hoffnagle based upon Mr. Yocum's emission factors is not reliable due to the erroneous assumptions built into the factors. Paragraph 32 is accepted. Paragraph 33 is rejected as irrelevant or contrary to the weight of the evidence. Paragraph 34 is rejected as irrelevant. Paragraph 35 is accepted. Paragraph 36 is accepted. Paragraph 37 is rejected as irrelevant, comment, argument, or immaterial. Paragraphs 38 and 39 are accepted. Paragraph 40 is accepted but is irrelevant. Paragraphs 41 through 44 are accepted.

The Issue Whether the alleged violation exists and, if so, whether orders for corrective action should be made final against respondents or either of them?
Findings Of Fact On October 17, 1984, Sunshine acquired from R & F what had been a filling station at the corner of U.S. Highway 98 and Laurie Avenue in Bay County, Florida. The old gas pumps had been moved some time before October 17, 1984. Only loose pipe connections leading to the underground storage tanks remained. The deed K & F executed in favor of Sunshine made no mention of these tanks. Respondent's Exhibit No. 1. Sunshine later contracted with Jake Walters, who began construction the following April to convert the site into a convenience store with gas pumps. On January 25, 1985, long before bringing any petroleum product onto the property, Jake Walters' construction foreman, John Kenneth Barnes, began taking up the two-foot slab of concrete that overlay K & F's underground storage tanks. The ground underneath the concrete smelled of gasoline. James Guris, who was overseeing the job for Sunshine, ordered work stopped and told Harold Millis, Sunshine's vice-president for real estate and construction, about the feel and smell of the soil. When Mr. Millis learned of the situation, he decided that DER should be notified. Because by then it was too late in the day to reach DER, Jim Guris called DER's office in Panama City on the following Monday, January 28, 1985. He spoke to DER's Grady Swann, who told him to file a discharge notification form with DER. Mr. Swann said removal of the underground tanks could go forward. Before removing the storage tanks, Mr. Barnes, or somebody at his direction, measured the depth of the tanks with a stick to determine how deep to dig. In this way two or three inches of gasoline were discovered in the bottom of each tank. Even though workmen secured a pump and pumped gasoline from each underground tank (into a 500-gallon tank mounted on a truck), they were unable to pump the tanks completely dry. In each of the three underground tanks, about a half inch of gasoline remained. With a crane and lifting rigs, they raised the tanks in an upright position, without spilling any gasoline. Except inside where the half inch of gasoline stood, the tanks and appurtenant pipes and tubing were dry. Mr. Guris ordered pressure tests done on the tanks, each a cylinder some five feet in diameter. Two of the tanks passed this test, but the third failed. That tank had a hole approximately one quarter inch in diameter a little left of center, about half way up one end of the tank. Groundwater on the site came within four and a half or five feet of the surface in early February of 1985. Because it contains less than 10,000 parts per million total dissolved solids, it is properly classified as G-II. A marine clay separates the surficial aquifer from the Floridan, but the surficial aquifer recharges the Floridan. Northeast of where the storage tanks were dug up and 300 to 350 feet way a two-inch well 390 feet deep supplies water from the Floridan aquifer to three households. Nobody has detected any odor or taste of gasoline in water from those wells. Grady Swann took soil samples on site on February 8 and again on February 26, 1985. On his first visit, he noticed no sheen on the surface of the water standing in the area excavated around the old tanks, smelled no odor emanating from the standing water and did not take a sample. On his second visit, he did notice evidence of groundwater contamination and took water as well as soil samples. Mr. Swann returned on March 11, 1986, with Kenneth L. Busen and Mike Wilson of DER's Operation Response Team and used a power augur to put in temporary wells from which additional water samples were taken. These tests confirmed suspicions that the old gas tanks had leaked and revealed groundwater contamination attributable to gasoline including, in some samples, more than 1,000 times the allowable concentration of benzene. Gasoline seeping through soil leaves residual hydrocarbons which contaminate percolating rain or other groundwater moving through the same soil. Petitioner's Exhibit No. 6 depicts the probable initial configuration of the plume of hydrocarbons in the vicinity of the old tanks. Contamination is moving down gradient to the northeast, spreading out but growing more dilute. The steps called for by the proposed corrective orders are a reasonable way to mitigate environmental damage.
Findings Of Fact Solite is a light weight aggregate mining and manufacturing facility located in Clay County, Florida. The mining operation extracts clay from quarries on site. That clay is then stored on site for use in the manufacturing. The Solite facility began its operations in Clay County in 1959. To convert the clay into a product, it is introduced into a rotary light weight aggregate kiln. There it is heated to a temperature of 1,900 to 2,100 degrees Fahrenheit. Once the raw feed has been subjected to the heat in the rotary kiln, it becomes light weight aggregate, a product that is used in the construction industry. Before being introduced into the kiln the raw feed clay is stored in a covered shed. When the kiln is operating clay is taken from the shed by front end loader and transported to a pug mill. The clay exits the pug mill onto a conveyor which has a weigh scale. From there, the raw feed clay is introduced into the kiln, at what is referred to as the cold end of the kiln. When a kiln is in operation the clay rolls from the cold end of the kiln through the other end during which transport the raw clay is heated. The clay is discharged from the kiln into a product cooler. From the product cooler it is transferred by a front end loader to a crushing, screening and storage area. Solite has three (3) kilns at the facility. They are kilns 1, 1A and 5. The kilns at the Solite facility are eight to nine feet in diameter and 130 to 160 feet long. When the kilns are in operation, they rotate at a speed of one to two revolutions per minute in producing the product. The fuel sources for heating the kilns on site are constituted of coal, number (2) fuel oil, propane or liquid burnable material (LBM). The LBM fuel source contains a variety of combustible waste materials. Among those waste materials are certain hazardous wastes. In 1973 Solite began to burn material which is now classified as hazardous waste. The combustion process that occurs in manufacturing the light weight aggregate creates gases that run countercurrent to the raw clay feed. The combustion gases are discharged at the same end of the kiln in which the raw clay had been introduced. In managing the hazardous waste used at the facility, Solite has installed two systems to treat the combustion gases before those gases are released into the atmosphere. Kiln No. 5 employs baghouse technology for air pollution control, a treatment system consisting of two compartments with approximately 960 bags. By contrast, the air pollution control devises for kilns 1 and 1A are individual wet scrubber systems for each kiln. As stated, the proposed permit would allow Solite to add an additional baghouse. Under this arrangement two of the existing kilns could be used simultaneously, with the existing baghouse No. 5 and the proposed baghouse No. 1 serving as air pollution control devices. The existing baghouse associated with kiln 5 has a lime injection system as part of the air pollution control system. The proposed permit contemplates a lime injection system as part of the air pollution control to be employed with the additional baghouse. The wet scrubbers associated with kilns 1 and 1A are designed to control particulate matter in emissions. The scrubbers are not designed to respond to other pollutants. To that end the wet scrubber with kiln 1A could meet applicable standards for particulate matter. The wet scrubber for kiln 1 could possibly meet the applicable standard for particulate matter if more spray nozzles were added to the scrubber. The present inability for kiln 1 to meet the applicable standard for particulate matter control is not significant because Solite may only operate kiln 1 or 1A separately. The water that is employed in the wet scrubbers becomes hazardous waste once it has been utilized in the attempt to respond to the pollutants in the air emissions generated by the respective kiln. In the past that water containing hazardous waste was introduced into a settling pond. Solite may no longer discharge that water into the settling pond in accordance with a regulatory decision that is not the subject for consideration in this case. Solite has made no other arrangements for disposing of the waste water. The proposed permit in this case would allow Solite to use the existing scrubbers to control emissions from kilns 1 and 1A in the instance where fuels were used in the manufacturing that were other than LBM with hazardous waste. At present kilns 1 and 1A have necessary permits for their use with the wet scrubber air pollution control devices, subject to the limitations that have been described. Under the terms set forth in the proposed permit the future use of LBM with hazardous waste in the manufacturing in kilns 1 and 1A would be only allowed when baghouse technology was employed as an air pollution control device. The baghouse air pollution control technology does not use water. Therefore it does not create a circumstance in which the treatment water contains hazardous waste. In that respect, kiln 1A ceased burning LBM with hazardous waste on December 1, 1990. That practice was concluded at kiln 1 on June 6, 1991. Kiln 5 ceased burning LBM with hazardous waste on August 19, 1991, but resumed burning LBM with hazardous waste on December 14, 1993 after the baghouse for that kiln was installed with its lime injection system. The baghouse proposed to be installed under the terms of the permit application is almost identical to the baghouse and associated equipment that were recently installed to operate with kiln 5. The baghouse and associated equipment with kiln 5 has achieved full compliance with all applicable state and federal air regulations as evidenced through compliance tests. As noted, with the baghouse at kiln 5 and the proposed baghouse for kilns 1 and 1A, the combustion gases are subject to treatment by lime. In that process the lime is introduced into the air emissions by pneumatic transfer. An alternative means for lime injection is established. That alternative would allow the lime to be introduced at the point where the fuel is fired at the kiln. Lime injection is used to control acid gases, either sulfur dioxide or hydrogen chloride. The combustion gases are also cooled by passing them through a heat exchanger that brings the temperature down from the exit temperature from the kiln temperature of 900 degrees Fahrenheit to approximately 400 degrees Fahrenheit. The cooled gases then enter the baghouse which is designed to control the particulate matter in the emissions. From there the remaining gases are discharged into the atmosphere. It takes four to five seconds for the combustion gases to go from the kiln through the heat exchanger proposed by this project. The particulate matter is in the form of dust that is collected in the baghouse. That dust is removed through a screw conveyor and pneumatically transferred to a kiln storage bin. The air involved in that pneumatic transfer is discharged through a small baghouse. The clay fines in the kilns bin are reintroduced into the pug mill, conveyed and mixed with raw clay before the clay fines are reintroduced into the manufacturing process in the kiln. The clay fines may also be transported from the kiln storage bin to the crusher and introduced into the finishing process for the product. On November 30, 1992, Solite made application for the permit at issue. Solite sought permission to modify the existing facility by constructing duct work that would connect kilns 1 and 1A to the kiln 5 baghouse, to construct and temporarily operate the additional baghouse and to connect kilns 1 and 1A to the existing pug mill filter receiver and clinker hopper filter (the filter receiver associated with the crusher). The connection of kilns 1 and 1A to the existing pug mill filter receiver and clinker hopper filter is to control the particulate matter that is captured in the baghouses. The existing pug mill filter receiver and clinker hopper filter presently serve kiln 5. If allowed the opportunity to construct a second baghouse, Solite contemplates using the second baghouse with kiln 1 or 1A. The arrangement contemplated by the proposed permit would allow kiln 1 or 1A to operate simultaneously with kiln 5. The bags in the proposed baghouse would be about six inches in diameter and twelve feet long. As the particulate matter in the air emissions enters the top of the baghouse it passes through these bags. That particulate or dust is collected on the surface of the bags, while the air that has gone through the filtration process exits through the stack to the baghouse and into the atmosphere. The dust that collects on the bags forms a "filter cake." Once a certain atmospheric pressure is achieved in the baghouse a predetermined jet of air is blasted down the bags blowing the filter cakes away from the bags. This allows the cakes to fall down into the bottom of the baghouse where a screw-auger moves that material to one end of the baghouse hopper. From there it is removed through an air lock and pneumatically transferred to the clay fines bin. The proposed baghouse would utilize a continuous monitor that is installed with the baghouse to measure the particulate matter concentration in the clean air section of the baghouse. Should a hole appear in one of the bags, that would cause a increase in the particulate concentration. Then a signal is generated by a broken bag detector which alerts the operator that a problem exists and the bag needs to be replaced. There are access doors into the baghouse that allow the operator to enter the baghouse to inspect the bags and replace them as needed. When the Department reviewed the permit application, it issued a notice of intent to grant a permit and a proposed permit. Petitioner's timely protested the intent to grant. Before hearing the Department issued two amendments to the proposed permit. It is the second amendment which forms the basis for proposed agency action. Solite does not oppose the terms set forth in the second amendment. Petitioners do oppose the grant of the second amended permit. By the actions which the parties have taken in this case, it would appear that they have conceded the standing for Petitioners to bring the challenge to the grant of a permit. The proposed project would not increase the capacity for the manufacture of light weight aggregate products. The amount of fuel used in that manufacturing and the hours of operation when compared to opportunities presently permitted would not be increased. The maximum rate of feed of authorized LBM that could be incinerated in kilns 1 and 1A does not increase when comparing the application to the existing permits for kilns 1 and 1A with wet scrubbers. The removal efficiencies with the proposed baghouse exceed or are equal to those with the wet scrubber systems when examining control of emissions of air pollutants that must be addressed. Clay County is an attainment area for all air pollutants. In considering the application, the Department determined this to be a construction request with a right to temporarily operate the equipment to check its performance. The Department considered the permit request to be one related to a stationary installation which will reasonably be expected to be a source of air pollution. See Section 403.087(1), Florida Statutes. In the proposed permit for baghouse No. 1 the Department intends to impose certain restrictions on emissions that were specified in the permit issued for the baghouse No. 5. The Department in its proposed permit employs a process similar to that set forth in the January 23, 1993 settlement agreement related to kiln No. 5. In determining the acceptability of the proposal the Department looked to Rule 62-730.181, Florida Administrative Code which speaks to standards for the management of specific hazardous wastes and specific types of hazardous waste management facilities. In particular the Department utilized that rule in its terms wherein the rule incorporates by reference 40 C.F.R. Part 266, Subpart H, as it is designed to regulate hazardous waste burned in a boiler or industrial furnace. The regulations in 40 C.F.R. 266, Subpart H, are referred to as the Boiler and Industrial Furnaces regulations (BIF). The Solite kilns are industrial furnaces within the meaning as defined in 40 C.F.R. 266, Subpart H. The Department in its proposed permit would impose the terms set forth in 40 C.F.R. 266, Subpart H, related to the maximum concentrations of certain constituents in the LBM with hazardous wastes and the air emissions produced by their destruction. By imposing those requirements the Department is operating independently. It is not through this permit review administering the BIF regulations as set forth in 40 C.F.R. 266, Subpart H under authority from the United Stated Environmental Protection Agency and for the benefit of that federal regulatory agency. The Department has required that Solite address the combined emissions from metals and other air pollutants for all sources at the facility. By this requirement the Department intends to assure that those emissions do not result in ambient air concentrations that would harm or injure human health or welfare, animal, plant, or aquatic life or property. To demonstrate those assurances Solite was expected to conduct modeling of the emissions of metals and chlorine which could be emitted from the facility. That modeling was properly done. The requirement for modeling was in accordance with Section 403.161, Florida Statutes. In association with this requirement the Department referred to the BIF regulations at 40 C.F.R. 261. The proposed permit is considered in accordance with Rule 62-296.320, Florida Administrative Code, related to the control of air pollutants which cause or contribute to an objectionable odor. The requirements within the proposed permit include the necessity for Solite to establish reasonable precautions to minimize unconfined emissions of particulate matter as described in Rule 62-196.310(3), Florida Administrative Code. As stated in the proposed permit, if kiln 1 or 1A were in operation using the wet scrubbers they must conform to existing permits associated with kilns 1 and 1A, but those opportunities would only pertain to the instance in which the fuel sources are other than LBM with hazardous waste. For Solite to use wet scrubbers as pollution control devices for kilns 1 and 1A in an instance in which LBM with hazardous waste was used for fuel, the treatment efficiency for kiln 1 would have to be improved in the manner described and the treatment water that contained hazardous waste must be disposed of other than by placement in the settling pond. The existing wet scrubber systems for kilns 1 and 1A are not closed systems which continue to re-circulate the scrub water (a closed scrub water containment system). There is no proposal to install a scrubber water re-circulation system. If such a system were installed an arrangement would be necessary for periodically taking the scrubber water and disposing of that water off-site. Without a system for containing and re-circulating the scrubber water which contained hazardous waste, and periodic disposal of that scrubber water, Solite may not use kilns 1 and 1A with a scrubber when burning LBM with hazardous waste. This is true even though the Solite air emissions control device for kiln 1A using the wet scrubber does meet applicable air emissions standards and the scrubber system permitted with kiln 1 has the possibility to meet air emissions standards. Therefore, if kilns 1 or 1A were used with a baghouse this would create a net increase in air emissions when using LBM with hazardous waste as a fuel source. Such an arrangement would not exceed the theoretical air emissions associated with the wet scrubbers for kilns 1 or 1A when using LBM with hazardous waste that are presently set forth in the existing permits for those kilns. But the proposed permit recognizes the problem with the scrubber systems by limiting the use of the scrubber systems to those occasions in which LBM with hazardous waste is not used as a fuel. The proposed permit specifically prohibits the use of kiln 1 and 1A simultaneously. A baghouse or scrubber may only control the emissions from one kiln at a time in accordance with the proposed permit. The Oldover Corporation or another facility permitted to manage hazardous wastes under various provisions at 40 C.F.R. shall be the supplier of LBM with hazardous wastes. Under the terms of the proposed permit Solite is responsible for the LBM with hazardous wastes meeting all the requirements in any applicable state, federal and local regulations. The proposed permit limits the constituents in the LBM with hazardous waste. It does not allow any hazardous waste that is listed for dioxin or derived from the dioxin-listed waste. As set forth in the proposed permit, organic cyanides, sulfide, mercaptans, insecticides, pesticides, herbicides, electroplating waste or radioactive material regulated by the State of Florida, Department of Health and Rehabilitative Services are not allowed to be part of the LBM. Other limitations are placed on the LBM with hazardous fuel concerning its constituents. They are set forth in proposed condition number 22 to the proposed permit. In accordance with the proposed permit, prior to submitting an application for an operating permit, which would allow LBM with hazardous waste to be burned, Solite is required to conduct testing at the facility for chlorinated dibenzo-p-dioxin and dibenzofuran, pursuant to a test plan approved by the Department. The proposed permit addresses test requirements and reports under various provisions set forth in Rule 62-297, Florida Administrative Code. The proposed permit reminds Solite that: Nothing in this permit shall exempt the permit to you from the requirements of 40 C.F.R. 761, polychlorinated bolychlorinated biophenyls, 40 C.F.R. 266, Subpart H, hazardous waste burned in boilers and industrial furnaces, and Chapter 62-730, Florida Administrative Code, hazardous waste, or any other requirements outside the purview of the Department's air regulation (Chapters 62-296 and 297, Florida Administrative Code). The permittee shall obtain such state and federal permits, when applicable, pursuant to any hazardous waste regulation (Rule 62-4.160, Florida Administrative Code). The proposed permit allows for an extension of the construction permit upon request of the Bureau of Air Regulation within the Department. The proposed permit makes it incumbent upon Solite to submit an application for an operation permit to the northeast district of the Department at least ninety (90) days prior to the expiration date of the construction permit. The proposed permit would allow kilns Nos. 1 and 1A to operate 24 hours a day, 7 days a week, 52 weeks a year, but no more than 760 hours during any calendar year, but not simultaneously. Concerning hazardous wastes in the LBM, procedures for testing those fuels to be used at the Solite facility are set forth in the waste analysis plan in the hazardous waste facility permit for the Oldover Corporation and the waste analysis plan for Solite. Oldover supplies those fuels to Solite. Under the waste analysis plan the generator of the waste material must complete a waste profile indicating the type of waste and its constituents which the generator proposes to supply to the facility. Initially Solite evaluates the waste profile to determine if the waste material meets all the necessary requirements for acceptance as a hazardous waste fuel for Solite. If the profile is acceptable, a representative sample is obtained from the waste generator. This sample is analyzed for a comprehensive set of parameters including physical characteristics, metals and organic compounds. If the representative sample indicates that the waste stream is acceptable it is approved and shipments are made to the Oldover facility adjacent to Solite. Once the waste stream has been approved by Solite and shipments are made, Oldover reviews the manifest associated with each shipment to determine the existence of any prohibitive constituents in the fuel before the fuel is accepted. Oldover tests the wastes for a limited number of parameters to determine whether or not the shipment conforms with the pre-established waste profile. If discrepancies are discovered between the waste profile and testing results the shipment may be rejected if the problems with the shipment cannot be reconciled with the anticipated waste profile. Comprehensive waste analysis are performed on an annual basis as well as at the initial point at which Solite begins to do business with a waste generator or upon the occasion when there is a significant change to the generator's waste stream. As it appears, the LBM with hazardous waste obtained from outside generators is generated off-site. Through this processes Solite has provided reasonable assurance that the use of LBM's with hazardous waste envisioned by the proposed permit will not allow the burning of hazardous waste that is listed for dioxin or derived from the dioxin-listed wastes: FO20, FO21, FO23, FO26 or FO27 as specified in 40 C.F.R. 261, Subpart H, or organic cyanides sulfites, mercaptans, insecticides, pesticides, herbicides, electroplating waste or radioactive material regulated by the State of Florida, Department of Health and Rehabilitative Services. Solite has provided reasonable assurance that the LBM with hazardous waste will be properly analyzed to quantify the concentration of any constituent that may reasonably be expected to be in the waste. Those constituents will be identified and quantified, if present. This process of identification and quantification will be at levels detectable by analytical procedures prescribed in EPA method SW-846. That method is the prescribed method for analyzing hazardous LBM under the BIF rules. As a means to promote reasonable assurances that the proposed project will comply with applicable state and federal emissions standards, emissions from kiln 5 using its baghouse have been tested and the emissions at kiln 5 using the baghouse meet all applicable state and federal emission standards. Given that the proposed baghouse for kilns 1 and 1A will be very similar to the baghouse associated with kiln 5, it is to be expected that the emissions from kilns 1 and 1A using the proposed baghouse would be comparable to the experience with kiln 5 and its baghouse. Using a baghouse results in significant reductions in the emissions of particulate matter when compared to the experience with wet scrubbers. The emissions from the proposed project will not exceed emission standards for particulate matter. The use of the lime injection system with the proposed baghouse will decrease emissions of sulfur dioxide. The emissions from the proposed project will not exceed standards for sulfur dioxide. Neither the existing wet scrubber system nor the baghouse system are expected to have any significant impact on nitrogen oxide emissions. Consequently, there will be no significant change in nitrogen oxide emissions associated with the installation of the proposed baghouse. The emissions from the proposed project will not exceed emission standards for nitrogen oxides. The proposed baghouse will result in a reduction in the emissions of metals due to the increased efficiency in the removal of particulate matter. The emissions from the proposed project will not exceed emission standards for metals. The proposed baghouse will result in a reduction in mercury emissions due to increased efficiencies in the removal of mercury in particulate form. The proposed baghouse will not cause a change in the emissions of hydrogen chloride when compared to the experience with the wet scrubbers. The levels of hydrogen chloride when using the baghouse as a control device will not exceed any standards. Nor will there be emissions in excess of standards for chlorine gas. The proposed baghouse when contrasted with the experience in the use of wet scrubbers will not change the amount of emissions of organic materials. The proposed baghouse when contrasted with the wet scrubber system will result in a reduction of the emissions of dioxins and furans. The proposed project will comply with standards applicable to dioxins and furans by exclusion from the LBM and limiting the inlet temperature to the baghouse. The proposed permit prohibits the facility from accepting any dioxins bearing waste. The fuel is screened to insure that it does not contain dioxin. PCB's in excess of five parts per million are not allowed. This is a means to limit the formation of dioxins and furans from the PCB's. The maximum temperature of gases entering the baghouse is established at 450 degrees Fahrenheit and an automatic shut-off device is required if this temperature is exceeded in order to control the secondary generation of dioxins and furans. The inlet temperature to the baghouse is set at 425 degrees. The modeling that was done to examine emissions of metals and chlorine provided reasonable assurances that the ambient concentrations caused by the impact of these pollutants from this facility will be less than the Department's annual air reference concentrations, as a means to ensure that harm or injury to human health or welfare, animal, plant or aquatic life or property does not occur. Solite is required by the terms of the proposed permit to have continuous emission monitors for carbon monoxide and hydrocarbons. When the emission standard for carbon monoxide or alternatively hydrocarbons nears the exceedance level, then the automatic waste feed shut-off is activated to assure that the carbon monoxide or, alternatively, hydrocarbon emission standards are not exceeded. Kiln 5 with its associated baghouse has demonstrated a destruction and removal efficiency for regulated organic pollutants in excess of 99.99 percent. Having similar technology, the proposed permit for a baghouse can be expected to meet the 99.99 percent destruction and removal efficiency for organic pollutants. The addition of the proposed baghouse with its associated features provides reasonable assurance that the particulate matter standard of 0.08 grains per dry standard cubic foot corrected to seven percent O2 will be met. As a protection against exceeding emission standards for various pollutants the proposed permit requires that Solite continuously monitor for carbon monoxide, oxygen, baghouse inlet temperature and sulfur dioxide at levels established in the proposed permit. Furthermore, the proposed permit requires that an automatic shut-off device be installed to maintain established emissions limits for temperature, oxygen or hydrocarbons. Such devices have been installed on the existing kiln 5 with its baghouse. Efficient combustion can be expected in kilns 1 and 1A based upon residence time for burning, turbulence, temperature and oxygen availability. The residence time for the fuels is approximately four seconds. The rotation of the kilns and movement of the clay material ensures adequate turbulence. The temperature of the kiln must be maintained at or above 1,800 degrees Fahrenheit and the fuel feed of LBM with hazardous waste is automatically shut-off if the temperature falls below 1,850 degrees. Oxygen levels are to be continuously monitored. The gas flow rates for fuel introduced into the kiln may not vary significantly. These arrangements are contained in the proposed permit. The re-introduction of clay fines or dust into the kiln to be incorporated into the product has been taken into account in establishing estimates of emissions for kilns 1 and 1A. That phenomenon has been measured in emissions for kiln 5. In using the dust Solite will not create conditions which violate standards for emissions. To support these findings all experts who testified at the hearing agreed that the proposed project will meet all applicable rules and emission standards. Solite has established reasonable assurances concerning those standards. The Solite application was sealed by a professional engineer, Dr. John Koogler, who was among those experts mentioned. The Solite facility uses an industrial furnace which is similar in design to furnaces regulated by the Environmental Protection Agency in its hazardous waste regulatory program. Nothing about the facility is extraordinary, thus requiring a more rigorous regulatory response to this facility which uses LBM with hazardous waste in kiln No. 5 and proposes to do so through the project under consideration. It was not shown that the Department must impose its "Air toxics" permitting strategy for controlling toxic emissions from stationary sources at levels which will not endanger public health in order to adequately consider the proposed project. The "Air toxics" permitting strategy is a non-rule policy. Although not specifically required by rule or standard Solite performed additional modeling concerning the emissions of organics from the facility with the advent of the use of the proposed baghouse. The modeling indicated that there would not be an exceedance of the no threat levels established in the state air toxics strategy. Similarly, although not required, Solite conducted additional modeling of dioxins emissions which indicated that there would be no significant risk posed as a result of the proposed project. Solite has qualified for interim status under the United States Environmental Protection Agency (EPA) regulations to burn hazardous waste at its facility. Solite has filed EPA required precompliance certification for all three kilns and certification of compliance for kiln 5. Solite has obtained an extension from EPA for filing their certification of compliance for kilns 1 and 1A. In addition Solite has submitted an application for hazardous facility permit to EPA and this application is currently under review by EPA. In reviewing the permit application past violations of statutes and rules were considered by the Department. This was done to determine whether Solite had provided reasonable assurances that the Department standards in application to the proposed project would be met. The Department correctly decided that Solite's past violations did not justify denial of the permit. Those violations were not severe and Solite corrected the problems. Furthermore, the proposed project would improve air pollution control to the extent that it reduces or eliminates problems that led to the previous violations.
Recommendation Based upon a consideration of the facts found and the conclusions of law reached, it is, RECOMMENDED: That a final order be entered which grants the construction permit for the air pollution source subject to the provisions set forth in the second amended proposed permit.

Findings Of Fact DER is the agency that has been charged by statute with the responsibility of administering programs to advance the legislative policy to preserve and protect air quality. Chapter 403, Florida Statutes (1977). DER has adopted what is commonly called its "Complex Air Source Rule". The Rule has been codified in Chapter 17-2, Florida Administrative Code. A copy of Chapter 17-2 was received into evidence at the hearing. The Complex Air Source Rule requires that a permit be obtained before certain potential sources of air pollution are constructed or operated. An applicant for a permit is required to provide reasonable - assurances that the proposed project will not violate DER's air quality standards. The rule establishes air quality standards for the following pollutants: sulphur dioxide, particulate matter, carbon monoxide, photochemical oxidants, hydrocarbons, and nitrogen dioxide. The Petitioners own property along Gulf Boulevard in Treasure Island, Pinellas County, Florida. The Department of Transportation has applied to DER for a complex air source permit to engage in a road widening project along Gulf Boulevard. Petitioners are parties to an administrative proceeding currently pending before the Division of Administrative Hearings. The issue in that proceeding is whether DER should grant the Department of Transportation the requested permit. The parties have stipulated that the Petitioners have standing to maintain the instant action. In its Motion to Intervene the Jacksonville Transport tation Authority alleged that it is proposing construction of an expressway system in Duval County, Florida. The Intervenor alleges that it will need to obtain a complex source permit from DER in order to engage in the construction. The Intervenor presented no evidence respecting these allegations at the hearing. DER's rule 17-2.05(3), Florida Administrative Code, provides for complex air source permits. A "complex source" is defined in Rule 17- 2.05(8)(a)(1) as follows: Any facility or group of facilities, which is a source of air pollution by reason that it causes, directly or indirectly, significant increases or emissions of pollutants into the atmosphere or which reasonably can be expected to cause an increase in the ambient air concentrations of pollutants, either by itself or in association with mobile sources. Roadways and widened roadways constitute complex sources under the definition. Permits must be obtained from DER before new roads, or road modifications can be constructed. Rule 17-2.05(8)(c) 3-5. Rule 17-2.05(8)(b) provides: No person shall construct or modify or operate or maintain any complex source of air pollution which results in or causes an increase in ambient pollutant concentrations in violation of the ambient air quality standards. DER may not issue a complex air source permit unless it is reasonably assured that the proposed project will not violate the ambient air quality standards set out in Rule 17-2.06, and in Table 3 thereof. The applicant is required to submit such information as DER requires to make its determination. Rule 17- 2.05(8)(d) provides: Any person seeking a permit shall submit such information that is necessary for the Department to determine that the complex source will not cause a violation of Ambient Air Quality Standards and submit to the Department such information that shall include, but not be limited to: The nature and amounts of pollutants to be emitted or caused to be emitted by the complex source, or by associated mobile sources, and an air quality impact statement. The location, design, construction and operation of such facility. The Petitioners contend that DER has a practice of requiring applicants for complex source permits to submit information, and to provide the requisite reasonable assurances only with respect to projected emissions of carbon monoxide. It is alleged that DER does not require applicants to submit data respecting other pollutants, or to provide any reasonable assurances with respect to the other pollutants described in DER's Ambient Air Quality Standards. It is further alleged that DER evaluates only expected emissions of carbon monoxide when evaluating an application for a complex air source permit. These allegations are not supported by the evidence. DER has a policy of requiring applicants for complex air source permits to submit in the initial application only data respecting projected carbon monoxide emissions. With respect to automobile related pollutants, carbon monoxide is known as a controlling pollutant. Automobile related pollutants essentially are carbon monoxide, hydrocarbons, and nitrogen oxides. A decrease of carbon monoxide emissions causes a greater decrease in hydrocarbon emissions. A decrease in carbon monoxide emissions causes a decrease of nitrogen oxide emissions at a slightly reduced percentage. Changes in ambient levels of these related pollutants can be predicted by considering carbon monoxide data. Furthermore, high concentrations of carbon monoxide are a localized problem. High carbon monoxide readings generally reflect one or just a few sources of carbon monoxide emissions within a localized area. High readings of hydrocarbons, nitrogen dioxide, and photochemical oxidants, on the other hand, are not localized, but rather reflect a number of pollutant emitting activities over a broad area. DER has established monitoring stations, where concentrations of pollutants are measured. Data obtained from these stations is utilized to provide DER with information as to areas that experience high concentrations of hydrocarbons, nitrogen oxides, and photochemical oxidants. When a project is proposed in such an area, DER requires applicants to submit ad ditional data respecting projected emissions of these pollutants that would result from the project. Such additional data has been requested by the Department in several cases. Where there is no indication that concentrations of these pollutants are occuring in an area, DER is able factually to assure itself that a given project will not result in violations of the standards respecting these pollutants by considering the carbon monoxide data. It is for this reason that applicants are not initially required to submit data respecting pollutants other than carbon monoxide. DER is able to assure itself that roadway projects will have no impact upon concentrations of sulphur dioxide and particulate matter because these are not pollutants that are associated with automobiles. DER's policy of not requiring applicants to submit data respecting pollutants other than carbon monoxide does not relieve an applicant of its duty to provide information necessary for DER to determine that the proposed project will not cause violations of any of the ambient air quality standards. The Department utilizes its own data in making such determinations, and if a project is proposed in an area where there are high concentrations of pollutants other than carbon monoxide, DER requires the submission of further data. DER's practices and Policies are thus not contrary to its rules, and the practices and policies do not constitute rule making.
Findings Of Fact The Petitioner and his father own and operate the Hiland Park Laundry, a laundromat located at 2431 Highway 231, Panama City, Florida. The Petitioner purchased the business in 1975 and has operated continuously since that time. Wastewater from the laundry, as well as a trailer on the property, passes through a "trickling filter" wastewater treatment facility consisting of primary and secondary settling tanks as well as a trickling filter, thus discharging the treated effluent into a drainage ditch adjacent to the Petitioner's property line, from which drainage ditch the effluent is discharged into Beatty Bayou, a Class III water of the State. The treatment plant and disposal system has been operating since the early 1970's, prior to the Petitioner's purchase of the laundromat and treatment and disposal facility. In 1980, the Petitioner applied for an operating permit for his wastewater treatment facility. Because the discharge from the facility violated the effluent limitations of Chapter 17-6, Florida Administrative Code, the Petitioner was only issued a Temporary Operating Permit on February 2, 1981, which was modified by virtue of the letter from DER on June 8, 1981. The pertinent conditions in the TOP provided that the discharge from the Petitioner's wastewater treatment system must meet the requirements of Chapter 17-6, Florida Administrative Code, as to the quality of its effluent prior to its expiration. Failure to meet that condition would result in a denial of a Permanent Operating Permit and the denial of any further TOP. The pertinent effluent limitation which the TOP (and rules) required the facility to meet was 90 percent removal of biochemical oxygen demand and suspended solids. Since the issuance of the TOP, the discharge from the plant has seldom met those standards. Upon applying for the TOP, which is the subject of this proceeding, the Petitioner failed to present any concrete plans for improving the quality of the effluent from his plant. He merely stated his acknowledgment that, although the system does not comply with current DER requirements, that it will be dismantled upon the Bay County Regional Sewage Treatment and Disposal System becoming available at his location. It is not established, however, that there are any current plans to extend public sewer service to the vicinity of the Petitioner's property at the present time. (DER Exhibit 9) Upon the issuance of the Notice of Intent to Deny the request for the TOP, the Petitioner requested a formal proceeding and the cause was set for hearing before the undersigned on September 24, 1982. At the time of the hearing, the parties agreed on the record to a continuance on the basis that the Petitioner would submit within 60 days a plan certified by an appropriate engineer for a design to bring the discharge effluent into compliance with the effluent parameters of Chapter 17-6, Florida Administrative Code. It was suggested at that time to the Petitioner that his plant and system might comply with the permit exemption contained in Rule 17-4.60, Florida Administrative Code, which provides that such plants are exempt from permitting requirements if they incorporate a trickling filter, a sand filter, as well as a drain field. The Petitioner elected to avoid purchasing a sand filter unit inasmuch as a civil engineer he consulted informed him that the purchase and installation price for such a unit would be approximately $17,000.00, with the attendant drain field estimated to cost an additional $13,000.00. It was established contrarily however that because of the actual peak and average flows of the plant which equate to a daily hydraulic loading on the proposed sand filter of 7,000 gallons per day and 6,000 gallons per day, respectively, that a much smaller sand filter would be required, at a much reduced price. Thus, it was established that a figure of $9,000.00 to $10,000.00 would be the appropriate cost of installing the sand filter which would exempt the facility from the permitting requirements. The concrete slab proposed to be used by the Petitioner's engineer at a cost of in excess of $4,000.00 would not be necessary with a properly designed sand filter with underdrains and grated gravel courses. Based upon his own engineer's estimate of approximately $30,000.00 for the required upgrading, the Petitioner informed the Department that he was not able to underwrite such a high expense and would prefer to find some other solution to the problem. As of the date of the hearing, the Petitioner still was desirous of the Department conferring with him to find a less expensive solution to the problem, but failed to adduce any evidence to establish that such a less expensive solution (less than the solution proposed by the Department) existed. During the period the case was held in abeyance for 60 days after the scheduling of the first hearing in September, 1982, during which time the parties had agreed to seek a solution to the problem involving denial of the permit application, and thereafter until the subject hearing, the Petitioner made no substantial efforts to confer with the personnel of DER and attempt to arrive at a feasible solution to the treatment and disposal problem upon which the denial of the permit application was based. Carol Daugherty is a chemist whose firm supplies the Department with the Petitioner's monthly operating reports, and obtains samples of effluent upon which those reports are based. She performs the testing on the samples from the plant's effluent discharge and engages somewhat in operation of the plant. The Petitioner's discharge has consistently failed to comply with the BOD and total suspended solids effluent limitations listed in Rule 17-6.060, Florida Administrative Code, providing for 90 percent removal of those effluent constituents. William Young, accepted expert witness in the field of biology and water quality assessment, visited the site in February, 1982, and in April, 1983, taking water quality samples from a drainage ditch both upstream and downstream of the Petitioner's discharge point. Chemical analysis of the samples reveal that the Class III parameter for bacteriological quality (coliform bacteria) was violated downstream of the discharge point. An imbalance existed in the bayou in natural populations of aquatic flora and fauna establishing there to be violation of permissible nutrient levels in terms of the excessive deposition of nutrients from the Petitioner's plant into the drainage ditch and thence into the bayou. Mr. Pressley's facility is not the only source of discharge into the drainage ditch which discharges into the bayou, but is the primary source of discharge. Rick Bradburn also was accepted as a expert witness in the field of biology and water quality assessment. He has visited the Petitioner's facility on a number of occasions and periodically has reviewed the monthly operational reports supplied by the Petitioner. The Petitioner's effluent, on a regular basis, is characterized by excessive biochemical oxygen demand, excessive total suspended solids and excessive fecal coliform bacteria counts vis-a-vis the standards and the rules cited hereinbelow. The discharge from the Petitioner's facility thus seldom exceeds 85 percent removal of biochemical oxygen demand and suspended solids (over the past 23 months) and is characterized by excessive nutrient deposition in the Class III waters of the State. The Petitioner has known, or should have known, since shortly after February 2, 1981, when the original TOP was issued with the subject condition regarding required upgrading of the plant and disposal system, that additional upgrading would be required in order to render the effluent produced by plant less degradory. Since that time he knew, or should have known, that the failure to take steps to achieve such upgrading of the treatment and effluent disposal system would jeopardize his continued operation of his business. The Petitioner has made little effort to arrive at and submit plans to achieve a more qualitative level of effluent treatment and as of the time of the hearing had not yet submitted a reasonable compliance schedule nor any sort of commitment to construct needed additional treatment facilities, even though the parties do not dispute that the effluent produced by the plant does not meet the required standard of 90 percent removal of biochemical oxygen demand and suspended solids.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence in the record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is, therefore, RECOMMENDED that the application of Freddie Pressley for a Temporary Operating Permit allowing continued operation of a wastewater treatment and disposal facility in Bay County, Florida, be and the same is hereby DENIED. DONE and ENTERED this 23rd day of August, 1983, in Tallahassee, Florida. P.

The Issue There are two issues in these cases: (1) whether Tampa Bay Desal, LLC ("TBD") provided reasonable assurances that its permit application to discharge wastewater from a proposed seawater desalination plant, National Pollutant Discharge Elimination System ("NPDES") Permit Application No. FL0186813- 001-IWIS, meets all applicable state permitting standards for industrial wastewater facilities; and (2) whether Tampa Electric Company, Inc. (TEC) provided reasonable assurances that its proposed modification to an existing industrial wastewater facility permit, NPDES Permit Modification No. FL0000817-003-IWIS, meets all applicable state permitting standards.
Findings Of Fact Parties other than SOBAC Poseidon Resources, LLC wholly owns TBD as one of Poseidon Resources' subsidiaries. Poseidon Resources formed TBD, the successor to S&W Water, LLC, as a special purpose project company to properly staff and finance the desalination project. TBW entered into a 30-year purchase agreement with TBD (then known as S & W Water, LLC) in 1999 to build, own and operate the desalination facility. Poseidon Resources operates as a privately-held company and all stockholders are major corporations. Poseidon Resources opened for business in 1995 and has over $300 million in water processing assets under management. DEP is an agency of the State of Florida. The United States Environmental Protection Agency ("EPA") delegated its NPDES permitting program to the State of Florida and is run by DEP. TEC is an investor-owned electric utility serving Hillsborough, Polk, Pasco, and Pinellas Counties. TEC owns and operates the Big Bend generating station, an electric plant consisting of four coal-fired steam units having a combined capacity of approximately 1800 megawatts. SWFWMD is a water management district in the State of Florida. SWFWMD reviews and acts upon water use permit applications and protects and manages the water and water- related resources within its boundaries. TBW and all of its Member Governments are within the geographical and legal jurisdiction of SWFWMD. Pasco County is a political subdivision of the State of Florida, a member government of TBW, and is located within the jurisdiction of SWFWMD. Pasco County is a major source of the groundwater used by TBW. TBW is a regional public water supply authority. TBW is the sole and exclusive wholesale supplier of potable water for all its member governments of TBW, which are Hillsborough County, Pasco County, Pinellas County, the City of New Port Richey, the City of St. Petersburg, and the City of Tampa. TBW serves approximately 2 million customers. SOBAC SOBAC was incorporated as a Florida not-for-profit corporation in February 2000. The stated mission of SOBAC is to protect the environmental quality of the bays, canals, and waterways of the Tampa Bay area, and to ensure drinking water for SOBAC members in the Tampa Bay area. SOBAC was formed by a group of people residing primarily in the area of Apollo Beach. Apollo Beach is a waterfront residential community that was created by dredge and fill of wetlands, estuary, and bay bottom bordering the "Big Bend" area of Tampa Bay, where the community terminates in a "hammerhead" of fill over what was once a seagrass bed. Across the North Apollo Beach "Embayment," formed by the "hammerhead," is the discharge canal of TEC's Big Bend power plant. A corrugated metal barrier partially separates the embayment from the discharge canal. This discharge canal also will receive TBD's discharge after re-mixing with TEC's discharge. SOBAC initially was formed out of concern for the environment in the Big Bend area of Tampa Bay. However, there is no requirement that SOBAC members live in the Apollo Beach area, or even in the vicinity of Tampa Bay, and SOBAC's geographic area of concern has broadened somewhat beyond the Apollo Beach area. In order to become a member of SOBAC, one need only sign a card. Prospective members are asked to donate $5 on signing up. Most members donate $5 or more. However, the donation is not mandatory. There is no requirement that members attend any meetings, or participate in any SOBAC activities. Section 3.1 of SOBAC's Constitution and Corporate By-Laws makes "active" membership contingent on payment of "the prescribed [annual] dues." Section 3.2 of SOBAC's Constitution and Corporate By- Laws requires SOBAC to establish annual dues, but no annual dues have been paid because no annual dues structure has ever been established. As a result, no annual dues have been "prescribed," and "active" membership does not require payment of annual dues. SOBAC claims to have approximately 1,000 members. These include all those who have ever become members. Approximately 700 live in the Appollo Beach area; approximately 50-75 of these members form the "core" of active members. Approximately 50-100 members live outside the Tampa Bay area; some of these outsiders probably are among the approximately 100 who are members by virtue of SOBAC's reciprocity agreement with another association called "Friends of the River." SOBAC has never surveyed its membership to determine how its members actually use Tampa Bay. However, the evidence was sufficient to prove that a substantial number of its members, especially among those who reside in the Apollo Beach area, enjoy use of the waters and wetlands of the Big Bend area for recreational activities such as boating and fishing. For that reason, if the activities to be permitted by DEP in these proceedings were to cause environmental damage, a substantial number of SOBAC's members would be affected substantially and more than most residents of distant reaches of the Tampa Bay area. Background of Desalination Project In 1998, the predecessor agency to TBW (the West Coast Regional Water Supply Authority), the six Member Governments and SWFWMD entered into an agreement specifically addressing impacts to natural systems through the development of new, non- groundwater sources, and the reduction of permitted groundwater withdrawal capacity from TBW's eleven existing wellfields from the then permitted capacity of 192 million gallons per day (mgd) to 121 mgd by December 31, 2002 (the "Partnership Agreement"). Pursuant to the Partnership Agreement, the existing water use permits for TBW's 11 specified wellfields were consolidated into a single permit under which TBW is the sole permittee. Prior to execution of the Partnership Agreement, the existing permits for these 11 wellfields allowed for cumulative withdrawals totaling approximately 192 mgd. Upon execution of the Partnership Agreement, the consolidated permit immediately reduced allowed withdrawals to no more than 158 mgd and required that wellfield pumping from the 11 wellfields be further reduced to no more than 121 mgd by December 31, 2002, and then to no more than 90 mgd by December 31, 2007. These withdrawal reductions are necessary to reduce the adverse environmental impacts caused by excessive withdrawals from the 11 wellfields, the majority of which are located in Pasco County. In order to replace the reduction of groundwater withdrawals, TBW adopted a Master Water Plan that provides for the development of specified new, alternative sources of potable water. The seawater desalination facility ("Desal Facility") is one of the cornerstone components of the Master Water Plan. This Facility will furnish 25 mgd of new water resources for the Tampa Bay area and must be in service by December 31, 2002, in order to meet the potable water needs of the residents of the Tampa Bay area. In exchange for the groundwater withdrawal reductions, SWFWMD agreed to contribute up to $183 million towards the development of new water sources that are diverse, reliable and cost-effective. SWFWMD has agreed to co-fund up to 90 percent of the capital cost of the Desal Facility. To comply with the terms and conditions of water use permits it has received from SWFWMD for other water withdrawals in the region, TBW must increase the water sources from which it withdraws water for distribution to its Member Governments in a timely manner. The Desal Facility is the essential means by which these permitting requirements can be met. For the past two years, the Tampa Bay area has been experiencing historic low rainfall and drought conditions. The Desal Facility is supported not only by TBW and its Member Governments, but also by SWFWMD since it is a drought-proof source of supply which has the greatest ability of any new water supply source to allow TBW to meet its members' potable water supply needs while also reducing pumpage from the existing 11 wellfields. In addition to its being a drought-proof source of potable water supply, the Facility will also provide diversity and reliability for TBW's sources of supply, and is a source that is easily expandable to provide additional potable supply that may be necessary in the future. Prior to deciding to proceed with a desalination project, TBW conducted four separate studies to look at the potential individual and cumulative impacts of a desalination facility on Tampa Bay and the surrounding areas, and in particular to evaluate the changes in baywide salinity due to the desalination discharge alone and in combination with the river withdrawals occasioned by other projects. Commencing in 1997, TBW conducted a procurement process that culminated in the award in July 1999 of a contract to S & W Water, LLC, now known as Tampa Bay Desal, LLC, to design, build, own, operate, and eventually transfer to TBW a seawater desalination plant to provide potable water to Hillsborough, Pinellas, and Pasco Counties and to the Cities of Tampa and St. Petersburg for 30 years. TBD's Desal Facility is co-located with the Big Bend Power Station owned and operated by TEC on the northeast side of Hillsborough Bay, in Hillsborough County, Florida. By discharging the concentrate from the Desal Facility to the power plant cooling water prior to its discharge to the power plant discharge canal, environmental impacts from the concentrate are minimized, and disturbance of the discharge canal is avoided. The costs avoided by utilizing the existing intake and outflow from the TEC power plant are reflected in the lower cost of the water to Tampa Bay Water, and ultimately its Member Governments. TBW is contractually bound to TBD to purchase all of the potable water that is produced by the Desal Facility for distribution to its Member Governments and to purchase the entire Facility in the future. With the exception of the NPDES permit at issue, TBD has obtained all of the over 20 other permits which are required for the construction and operation of the desalination facility. TBD has already invested approximately $20 million in this project. The total estimated capital cost of the desalination facility is $110 million. TBD has obtained financing of $42 million and expects to acquire permanent financing in the month of October 2001. SWFWMD agreed to subsidize up to 90 percent of the capital cost of the desalination facility payable to TBW over the term of agreement with TBD. TBD is contractually bound to TBW to complete and fully operate the desalination facility by December 2002. TBD Desalination Process Overview of Process In the instant case, desalination is performed through reverse osmosis ("RO"), a mechanical process wherein pretreated water under very high pressure is pressed against a very fine membrane such that only pure water can pass through it. The vast majority of salt molecules and other substance are eliminated from the water. The RO process is not heat or chemical driven. No additional heat load is being added as a result of the desalination discharge, and the desalination plant will actually result in a reduced heat load to the bay. The desalination facility will withdraw approximately 44.5 mgd of raw water from Units 3 and 4 of TEC's Big Bend cooling water system, produce approximately 25 mgd of product water for transmission to the regional water supply system, and discharge approximately 19.5 mgd of clarified backwash and concentrate water equally into each of the power plant cooling water tunnels for dilution and release into the discharge canal. During abnormal power plant operations including times when Units 3 or 4 are not in operation and during the summer months when the normal supply water intake temperature exceeds the operating temperature range of the RO membranes, a portion of the source water will be withdrawn from an auxiliary supply water system. The auxiliary supply water system consists of a supply pump and pipeline that withdraws water from a location downstream of the fine-mesh screens for Units 3 and 4. The total combined bay withdrawal flow for the power plant and the desalination facility cannot exceed 1.40 billion gallons per day ("bgd"). This limitation ensures that entrainment does not exceed the levels previously permitted for the site, and a new entrainment study pursuant to Section 316(b) of the Clean Water Act is not required. Pretreatment Process The desalination intake water is pretreated in a two- stage gravity filtration process with chemical additives. During pretreatment, ferric sulfates will be added to the desalination intake water to coagulate and capture suspended solids, organic material, and metals that exist in the raw water supply. In this first stage of the pretreatment process, the intake water runs through an aerated course sand filter. Aeration enhances the coagulative process and assists in the capture of organics, suspended solids, and metals. Aeration also occurs in stage two, which uses a fine sand filter pretreatment process. The backwash water from stage two recirculates to the stage one treatment process. The pretreated waters exits through a five micron cartridge filtration prior to entering the RO process. The aerated pretreatment filter backwash water from the pretreatment stage one pretreatment will be sent to a discharge sump for initial settling and then to a clarifier and filter press to remove excess water. Approximately 14 wet tons a day which includes organics, suspended solids, and metals that are removed through the coagulative process and captured from the gravity filters are removed off-site to a landfill. The desal concentrate and clarified backwash water will be combined in a discharge sump or wet well prior to entering into a discharge line manifolded to equally distribute the concentrate discharge into all of the available cooling water outflow tunnels or conduits of the power plant discharge. Reverse Osmosis Membrane Treatment The RO desalination process consists of a two-stage pass of the pretreated water through the reverse osmosis membranes. The RO pumps will force the water through the RO membranes at pressures ranging from 600 to 1000 pounds per square inch (psi). As a result of the RO process, approximately 25 mgd of purified water, also known as permeate, will be produced for delivery to TBW. TBD anticipates cleaning its membranes twice per year, perhaps less, due to the high level of pretreatment. Periodic cleaning removes silt and scale from the membrane surface. Dilute solutions of citric acid, sodium hydroxide, sulfuric acid, sodium tripolyphosphate, or sodium dodecyclbenzene compromise the constituents of various cleaning solutions, with the actual cleaning solution used dependent upon the actual performance of the system once it is placed in operation. Once the cleaning cycle is complete, the spent cleaning solution will be purged from the feed tank, membrane vessels, and piping and diverted into a scavenger tank for off- site disposal. Clean product water (permeate) will be fed to the feed tank and pumped into the RO membrane vessels. This process will continue until the pH of the purge water meets the Class III marine water quality criteria. The membranes will be rinsed with brine concentrate and permeate, and the rinse water will be directed to the wet well for discharge, with the concentrate into the TEC cooling water stream. TBD determined the chemical characterization of the membrane cleaning solution discharge. Cleaning solutions are not discharged in detectable concentrations. As further assurance, the permit requires toxicity testing immediately after membrane cleaning. Dilution of Discharge Water Co-locating the desalination facility with TEC's Big Bend power station allows the desalination concentrate to be diluted with TEC's cooling water prior to discharge into Tampa Bay. The point of injection of the desalination discharge will be located approximately 72 feet upstream of the point of discharge to the discharge canal to ensure complete mixing of the desalination concentrate with TEC's cooling water. This provides reasonable assurance that the desalination discharge will be completely mixed within the cooling water conduits. If all four TEC units are in operation and TBD is producing 25 mgd of finished water, the approximate dilution ratio of the desalination concentrate with TEC cooling water is 70:1. Historical TEC data indicates that a dilution ration of greater than 20:1 will occur more than 99.6 percent of the time, and a dilution ration of greater than 28:1 will occur more than 95 percent of the time. The dilution limitations in the proposed permit are more stringent than those required in Rule 62-302.530(18). The permitted dilution ratio complies with Rule 62- 660.400(2)(d) because it takes into account the nature, volume, and frequency of the proposed discharge, including any possible synergistic effects with other pollutants which may be present in the receiving water body. Comparisons of the Antigua, Key West, and Cyprus facilities are not applicable because those desalination facilities lack the initial dilution that will exist at TEC's Big Bend site. The proposed permit requires a 20:1 minimum dilution ratio at any given time, which may occur for no more than 384 hours per calendar year, and with the further limitation that the discharge at the 20:1 minimum dilution ratio shall not exceed 384 hours in any given 60-day period. At all other times, a minimum dilution ratio of 28:1 must be maintained. To ensure proper dilution and system operation, computer instrumentation in the desal facility will interface with TEC to continuously monitor the operations of TEC's four cooling tower condenser units. If any of the pumps shut down, an alarm will sound at the desalination facility and the computer system will automatically shut down the concentrate discharge to that specific condenser unit discharge tunnel. Further, the desalination plant will employ approximately 12 employees, with a minimum of two employees on duty at all times. TEC Permit Modification Big Bend power station has four coal-fired steam electric generating units. The power station is cooled by water that is taken in from Tampa Bay through two intake structures which are located along TEC's intake canal. One intake structure feeds cooling water to electrical power units 1 and 2 and the other feeds units 3 and 4. After flowing through the condensers, the cooling flows are combined into four separate discharge tunnels which outfall into TEC's discharge canal. The intake structure for Units 3 and 4 is equipped with fine-mesh screens and an organismal collection and return system that has been approved for use by DEP. The purpose of TEC's permit modification is to alter the internal piping in the facility to accommodate the desalination plant at the Big Bend site. TEC's permit modification allows for placement of an intake pipe from TEC's cooling water pipes to the desalination plant and a return pipe downstream from the intake pipe for the return of the desalination concentrate to TEC's cooling water discharge tunnels prior to outfall in the discharge canal. TEC's permit modification also allows for the placement of an auxiliary intake line by TBD to take additional water from behind the intake of units 3 and 4 up to TEC's maximum permitted limit of 1.4 billion gallons a day. The TEC proposed permit is conditioned to require TEC to maintain the structural integrity of both the steel sheet pile wall on the discharge canal and the breakwater barrier North of the discharge canal. TEC's permit modification does not request any changes to the operations of the Big Bend Generating Station. SOBAC Issues and Concerns SOBAC raised numerous issues and concerns in its petitions in these cases and in the Pre-Hearing Stipulation. However, some issues were elimination by rulings adverse to SOBAC during prehearing proceedings and final hearing. Based on the evidence SOBAC sought to elicit at final hearing and issues raised in its Proposed Recommended Order, other, earlier SOBAC issues and concerns appear to have been dropped. Remaining are essentially the following: increased salinity due to TBD discharge; alleged decreased dissolved oxygen (DO) from higher salinity; impacts of higher salinity and alleged decreased DO on marine plants and animals; alleged release of metals from sediments due to higher salinity and alleged lower DO, and effects on marine plants and animals; alleged monitoring deficiencies; alleged failure to utilize available technologies to lower salinity and raise DO; alleged deficient financial assurances; and various alleged resulting DEP rule violations. Description of Tampa Bay: Physical Properties The portion of Tampa Bay and Hillsborough Bay near the Big Bend facility is classified a Class III water body. Tampa Bay is a naturally drowned river valley, meaning that a deep channel exists as a result of natural forces. However, the channel has been deepened to 45 feet or greater to allow large ships to navigate the bay. This deepening of the channel increases the water flow of the head of the bay with the open gulf waters and allows this residual circulation to move more new water from the open Gulf of Mexico up into the bay. Ordinarily, circulation moves salt water up Tampa Bay and spreads it out onto the flanks of the bay where it then mixes with the freshwater. To complete this circulation, the water then flows back out towards the mouth of the bay, primarily along its flanks and shallower parts in the upper part of the water column. The water in Tampa Bay tends to flow faster in its deeper parts, both coming in and going out, and relatively slower in the shallow areas. The majority of flow of freshwater inflow occurs at the bay's flanks as can be seen very clearly in the salinity distributions. Mixing and Stratification Since the development of Tampa Bay from the 1880 condition to the 1972 and 1985 conditions, there is more mixing and exchange of water. Due to shoreline fills for development, such as Apollo Beach, there is less water that now comes in the bay than in the predevelopment condition. Tampa Bay is a fairly well mixed system from top to bottom. This is because the action of the tides basically acts like a big mix master. The bay is fairly shallow, less than four meters in depth on average. The tidal velocities can be as strong as two knots or about a meter per second. When the strong velocity pushes through shallow water, there is extensive overturning, where the bottom water is churned to the top and gets mixed very efficiently. That is very well seen in the observations during dry periods. Over 100 points in Tampa Bay were measured for temperature and salinity top, middle and bottom, and showed that they were very uniform throughout the bay. During periods of large volumes of freshwater input into Tampa Bay, freshwater is pumping into the bay faster than the tidal mixing can mix it from top to bottom. Therefore, in parts of Tampa Bay significant stratification is seen during many times in the wet season. During those times when rainfall is not as prevalent, tidal mixing once again dominates and the bay returns to a more well mixed system. The average tidal fluctuation for Tampa Bay is a range of two to three feet. Salinity As the tide in Tampa Bay comes in, it brings saltier water from the mouth of the bay toward the head of the bay, causing salinities to rise. As the tide recedes, bringing out fresher water from farther up the bay, salinities decrease. Over an individual tidal cycle, particularly during the wet season, a four or five part per thousand ("ppt") change in salinity will occur between a rising tide and a falling tide. During the dry season, tidal flushing is not as significant to salinity levels because not much difference exists in salinity from the head of the bay to the mouth of the bay. Even during the dry season, there is a one to two ppt change over a six to twelve-hour period in any given day. During the dry periods in 1990, salinities elevated up to about 33 ppt, with very little stratification. During the rainy periods, in June and July, salinities dropped rather drastically. In some areas, salinity dropped as low as to 20 to 22 ppt. However, in spite of these drastic seasonal differences, significant variation in salinity occurs as a result of tidal exchange. The Big Bend area is split by the dividing line between Hillsborough Bay and what has been classified Middle Tampa Bay. The salinity for Hillsborough Bay from 1974 through June 2001 at the surface ranges from 0.4 ppt to 38.2 ppt. The middle portion of the same water column contained a range from 2.5 ppt to 39.2 ppt, and the bottom portion showed a range from 3.9 ppt to 37.2 ppt. The average salinities during this time frame were as follows: top 24.2 ppt, middle 24.3 ppt and bottom 25.3 ppt. In the portion of Tampa Bay called Middle Tampa Bay, the surface level salinity ranged from 6.8 ppt to 38.2 ppt. At middle depth, salinities ranged from 7.4 ppt to 38.8 ppt. The bottom level salinities ranged from 11.9 ppt to 39.6 ppt. This is a large range of salinities. Tampa Bay near the Big Bend Area In the area near the Big Bend facility, the Mote Marine Laboratory survey data reflects that the salinity during May and June 2000 reached 33.4 ppt. Further, Mote Marine Laboratory data showed that the North Apollo Embayment area salinities were well mixed vertically throughout the system. The total volume of water exchanged into the North Apollo Embayment and associated canals during a mean tide is approximately 35 percent of the total volume of all water contained in that area. This tidal exchange occurs twice per day. The double diffusion process does not create high salinity in the bottom of the water column in the North Apollo Embayment. The double diffusion process, without any external influence, would lead to both surface and bottom layers of the water column reaching salinity equilibrium. Further, the turbulent mixing that occurs due to tidal processes and wind- induced mixing dominates over the double diffusion process. The Mote Marine Laboratory study conducted between May and early June 2000 did not detect any significant salinity stratification in the area near the Big Bend facility. Vertical stratification of salinity does occur but typically only during the periods of significant freshwater inflow and not in extreme drought or dry conditions. None of the Mote Marine Laboratory data detected any pockets of high salinity water or significant density stratification in the North Apollo Embayment. Estuarine Characteristics Tampa Bay is an estuary. Estuaries are semi-enclosed bodies of saltwater that receive freshwater runoff from drainage or riverine inflow, which measurably dilutes the salinity levels in the estuary. As a result, salinity levels in estuaries typically are highly variable, ranging from 0 ppt where rivers flow into estuaries, to as high as 40 ppt under conditions of low freshwater input or at estuarine mouths where they connect to the sea. There are naturally occurring dissolved oxygen levels below 4.0 mg/l in parts of Tampa Bay, including at Hillsborough County Environmental Protection Commission ("EPC") monitoring stations 9, 80, and 81, which are the closest stations to the proposed discharge. Dissolved oxygen in the bay decreases at night because photosynthesis ceases and respiration exceeds production. Other environmental parameters are also highly variable in estuaries. Therefore, the organisms that inhabit estuaries have adapted to tolerate these highly variable conditions. Estuarine organisms have adaptive means for tolerating changing salinity levels, either by conforming their internal salinity levels to the ambient salinity levels, or by actively regulating their internal salinity levels by intake or excretion of salt. Organisms that are adapted to tolerate a wide range of salinities within the estuary are termed euryhaline organisms. Essentially all of the common organisms in estuaries, including the Tampa Bay estuary, are euryhaline organisms, and therefore are capable of tolerating and living in a wide range of salinities and salinity changes that occur due to tidal, meteorological, and other natural forces in the estuarine environment. Extensive baseline biological studies performed on Tampa Bay reveal that the most common species in the Tampa Bay estuary tolerate salinity levels ranging from 5 ppt to 40 ppt. Seagrasses Five species of seagrass inhabit Tampa Bay. Seagrasses are photosynthetic underwater flowering plants that are typically limited in occurrence and distribution by the water clarity. This limits the depth at which seagrasses can grow. In Tampa Bay, seagrasses are limited to the fringes of the Bay, and are largely limited to depths of approximately three feet, although they can live in depths of up to six feet in clearer parts of the Bay. Seagrasses are very sensitive to increases in nutrients, like nitrogen and phosphorus. These nutrients encourage algae growth, resulting in competitive stress in seagrasses. Due to poor water quality caused by sewage discharge, dredging and filling, and other activities in the Bay, seagrass distribution in Tampa Bay decreased from an historic coverage of approximately 80,000 acres in 1950 to approximately 20,000 acres by 1982. Improvements in water quality, largely due to sewage treatment improvements, have allowed seagrasses to naturally recolonize to approximately 27,000 acres coverage, as of 1994. Wave energy affects seagrass distribution. Seagrasses cannot colonize and survive in areas subject to significant wave energy. For example, the portion of Tampa Bay dredged and filled to create the Apollo Beach "hammerhead" area was once comprised of a broad shallow-water shelf that diminished wave energy, allowing dense seagrass flats to cover the shelf area. Destruction of the broad shallow-water shelf with fill to create the Apollo Beach hammerhead has converted the area to a high wave energy system that is unsuitable for seagrass colonization and growth. Consequently, the only seagrasses inhabiting the Big Bend area are found approximately one kilometer north of the Big Bend power plant, in an area known as "The Kitchen," and approximately one kilometer south of the Apollo Beach hammerhead area. Additionally, there are ephemeral patches of seagrass inhabiting some limited areas of the North Apollo Embayment. Seagrasses are adapted to tolerate a wide range of salinities. They have specialized cells that enable them to deal with salt stress and with broad ranges of and fluctuations in salinity. These adaptations enable them to survive and thrive in estuarine environments. Of the seagrass species that live in Tampa Bay, one species, Ruppia maritima (widgeon grass), occurs in salinity ranges from zero to 40 ppt. Manatee grass, Syringodium filiforme, is most productive in salinities between 5 ppt and 45 ppt. The other three species, Halodule wrightii (shoal grass), Halophila engelmannii (star grass), and Thalassia testudinum (turtle grass), tolerate salinity ranges from approximately 5 ppt to 60 ppt. Seagrasses better tolerate higher salinity levels than lower salinity levels. Lower salinity levels are usually indicative of increased stream and land freshwater runoff, which usually is accompanied by increased turbidity and lower water clarity. Four of the five seagrass species that inhabit Tampa Bay typically reproduce asexually by producing rhizomes, rather than by flowering and producing seeds. It is not completely clear why seagrasses in Tampa Bay reproduce asexually rather than by flowering and seed production. However, recent research indicates that climatic temperature is the controlling factor for flower and seed production. In South Florida, where the climate is warmer, seagrasses reproduce by flowering and seed production. In Tampa Bay, the lower winter temperatures appear to be the limiting factor with respect to successful flower and seed production in seagrasses. Recent studies by the University of South Florida ("USF") marine laboratory indicate that naturally occurring fungal diseases may also limit successful flowering and seed production in seagrasses in Tampa Bay. Since most seagrass species that live in Tampa Bay tolerate and thrive in salinities of up to 60 ppt, the higher salinity levels in the estuary do not appear to adversely affect the ability of seagrasses to reproduce. In fact, the lower salinity levels, below 5 ppt, stress seagrasses and are more likely to adversely affect reproduction than do higher salinity levels. Mangroves Three major species of mangrove inhabit the Tampa Bay area: the red mangrove, black mangrove, and white mangrove. Mangroves inhabit the intertidal area, so they are subjected to daily tidal flooding and drying. Consequently, they must tolerate a wide range of variability in salinity levels and in water availability. Most mangroves tolerate soil salinity levels up to 60 ppt, close to twice the salinity of Tampa Bay. Mangrove mortality due to salinity does not occur until soil levels approach and exceed 70 ppt salinity. Mangroves are also adaptable to, and inhabit, freshwater environments. Phytoplankton and Zooplankton Plankton are life stages or forms of larger organisms, or organisms that have no ability for major locomotion, so they spend their entire life spans floating and drifting with the currents. Plankton are extremely productive in that they reproduce in very large numbers within very short life spans. Holoplankton are planktonic organisms that spend their entire lives in planktonic form. Examples include diatoms, which are a type of phytoplankton, and copepods, which are a type of zooplankton. Meroplankton are "temporary" plankton that drift with the currents in juvenile or larval stages, then either settle out of the water column and metamorphose into an attached form (such as barnacles) or metamorphose into mobile life forms (such as crabs, shrimp, and fish species). Phytoplankton are planktonic plant species and life forms. Zooplankton are planktonic animal species and life forms. Zooplankton feed on phytoplankton. There are approximately 300 species of phytoplankton, and numerous species and forms of zooplankton, found in Tampa Bay. Most phytoplanktonic and zooplanktonic species inhabiting Tampa Bay are euryhaline species capable of tolerating the wide range of salinity levels and abrupt salinity changes that occur naturally in the estuarine system. Most phytoplanktonic and zooplanktonic species and life forms in Tampa Bay tolerate salinity levels ranging from zero to 40 ppt. They appear to be more tolerant of the higher end than the lower end of this salinity range. Manatee The manatee is the only endangered or threatened species identified by the Florida Natural Areas Inventory as inhabiting the area where the desalination plant is proposed to be located. Manatees congregate at the Big Bend Power Station during colder months because they are attracted to the power plant's warmer water discharge. Manatees are considered to be estuarine species, but they have very broad salinity tolerance ranges. They migrate into and out of freshwater springs, through estuaries, into the Gulf of Mexico, and down to the Ten Thousand Islands, where hypersaline conditions frequently exist. Manatees routinely expose themselves to and tolerate salinities ranging from zero to more than 40 ppt. Fish The fish populations in Tampa Bay are comprised of a large number of marine euryhaline species. Due to their ability to osmoregulate their internal salinity levels, these fish species can inhabit salinity ranges from 5 ppt to as high as 40 ppt. Extremely extensive monitoring and sampling programs are currently being conducted in Tampa Bay and specifically in the vicinity of the Big Bend Power Station. The Hillsborough County EPC, SWFWMD, TBW, the United States Geological Survey ("USGS"), the Florida Marine Research Institute, USF, and Mote Marine Laboratory conduct separate biological monitoring programs that sample and monitor numerous biological parameters, including invertebrate infaunal and epifaunal species composition, abundance, and distribution; zooplankton and phytoplankton species composition, abundance, and distribution; emergent and submerged vegetation species composition, abundance, and distribution; and fish species composition, abundance, and distribution. These monitoring programs, which collect and analyze biological data from many areas in the Tampa Bay estuarine system, extensively monitor numerous biological parameters in the Big Bend area. Testing and Modeling Pilot Plant Although DEP's rules do not require the use of a pilot plant to demonstrate reasonable assurances, TBD installed a desalination pilot plant at the Big Bend site in November 1999. The pilot plant matched the hydraulics and configuration of the full-scale facility on a 1/1000 scale. The pilot plant used water from the Big Bend power plant discharge as its source water. The purpose of the pilot plant was to confirm design requirements for the desalination facility and to provide samples of intake water, filtered water, pretreated water, concentrate, and finished water to use for chemical characterization and analysis. Using a pilot plant is superior to using data from engineering projections or data from a different desalination facility because the pilot plant provides data specific to the Big Bend site. Data from the pilot plant were used to establish various effluent and other limits in the permit. Chemical Characterization Intake water, filtered water, pretreated water, concentrate, and finished water from the pilot plant were analyzed for over 350 parameters chosen by DEP to determine chemical characterizations and water quality. The pilot plant operation provides extensive chemical characterization of intake and discharge water composition and mass loading. This information was key in providing accurate information on the chemical composition and mass loading of the desalination discharge concentrate. With this accurate information on the components in the discharge water, DEP was provided more than sufficient reasonable assurance on the potential effect of the chemical components of the discharge. TBD tested the pilot plant discharge water for copper, nickel, other heavy metals, and those chemical constituents specified on the DEP chemical characterization form. The chemical characterization tested for concentrations of constituents based on a 12.8 to 1 dilution ratio, and even at that dilution ratio, did not exceed any of the state water quality parameters. However, to provide additional assurance that there will not be an exceedance of state water quality standards, the permit requires a minimum 20 to 1 dilution ratio. Dissolved Oxygen Saturation Testing Temperature and salinity affect the saturation point of dissolved oxygen ("DO") which is lowest when temperature and salinity are highest. DO saturation charts, which are typically used to determine DO saturation points, are not applicable because those charts do not contain the saturation point of DO at a temperature of 109 degrees Fahrenheit and a salinity of 79 ppt, which represents the worst case conditions for the proposed desalination facility. Bench-scale testing was performed on the undiluted desalination discharge from the pilot plant by heating discharge concentrate samples to 109 degrees Fahrenheit and aerating the samples until the DO stabilized and reached saturation point. The pilot plant bench-scale testing determined that the saturation point of DO in the worst case desalination concentrate using a temperature of 109 degrees Fahrenheit and salinity of 79 ppt was 5.7 mg/l. Toxicity Testing TBD conducted acute toxicity testing using a worst case scenario assuming a diluted effluent of one part desalination concentrate to 12.8 parts of power plant cooling water. Acute toxicity testing evidenced no mortalities, showing that the proposed discharge will not be a source of acute toxicity. TBD conducted chronic toxicity testing on raw concentrate from the pilot plant using a worst case scenario diluted effluent of one part desalination concentrate to 12.8 parts of power plant cooling water. The No Observed Effect Concentration (NOEC) for raw concentrate was determined to be 100 percent and the NOEC for diluted effluent was determined to be greater than 100 percent. The evidence did not explain these concepts, but it was clear from the tests that the proposed discharge will not be a source of chronic toxicity. TBD conducted its acute and chronic toxicity testing using protocols reviewed and approved by DEP. TBD's toxicity testing was also consistent with accepted EPA standards. Assessment of Potential Environmental Impacts TBD prepared an Assessment of Potential Environmental Impacts and Appendices ("Assessment") to analyze the potential biological impacts of the desalination plant discharge into the Tampa Bay estuary. The Assessment examined numerous physical parameters to determine the baseline environmental conditions in the portion of Tampa Bay proximate to the proposed desalination plant site. Among the physical parameters examined in determining the baseline environmental conditions were: salinity; sediment size and composition; metal content in sediments; and numerous water quality parameters such as transparency, biochemical oxygen demand, pesticides, dissolved metals, and pH. Consistency with SWIM Plan As part of the permitting process, TBD was required to demonstrate consistency of the proposed desalination discharge with the SWFWMD's Surface Water Improvement and Management (SWIM) plan, pursuant to Rule 62-4.242. TBD submitted an extensive SWIM consistency analysis, which is sufficient to meet the consistency requirement. Water Quality Based Effluent Limitation Level II Study TBD performed a Water Quality Based Effluent Limitation (WQBEL) Level II study pursuant to Rule Chapter 62- 650 for the purpose of determining the effect of the desalination plant discharge on salinity levels in the vicinity of the desalination plant discharge. TBD had the Danish Hydrologic Institute ("DHI") use the data collected through the WQBEL Level II study in its near-field model of the Big Bend area. See Findings 105-117, infra. DEP also used the data and the DHI model results to establish the salinity and chloride effluent limitations in the permit. The USF Far-Field Model The far-field model was prepared utilizing the Princeton model code. The Princeton model is well recognized and is generally accepted in the scientific community. The goals of the TBD far-field model performed through USF by Dr. Luther and his team were to evaluate the change in bay-wide salinity due to the desalination plant discharge, both alone and in combination with changes in salinity due to enhanced surface water system withdrawals under new consumptive water use permits issued to TBW by SWFWMD to provide other, additional sources of needed potable water supply. The primary goal was to provide DEP with the best science possible of the potential real effects of this desalination discharge into Tampa Bay. The modeling system of Tampa Bay utilized in this analysis was developed beginning in 1989. Dr. Luther and his team have continued to make refinements to the model over the last 12 years. Dr. Luther took the modeling system he had developed over the years for Tampa Bay and did three primary model scenarios. The baseline case reproduced the observed conditions during the 1990 and 1991 years--a very dry period in 1990 and a fairly wet period for 1991--as accurately as possible with all the boundary conditions estimated from observations. This was to capture an entire range of conditions in Tampa Bay. The baseline was then compared with validation data and other observations to ensure it was approximating reality. The second simulated scenario included the same effects as the baseline with the added effect of the desalination intake and discharge at the Big Bend facility. The third case approximated cumulative effects from the TBW enhanced surface water system river withdrawals according to the proposed permit withdrawal schedules. For each test case, it was assumed that only two of the four cooling units at the TEC Big Bend plant were in operation for an entire two-year period, a worst-case scenario expected to occur less than four percent of the time in any given year. The model included data on water levels, temperature, and salinity throughout Tampa Bay. In addition, it takes into account wind blowing across the surface of Tampa Bay, rainfall, freshwater inflow from rivers, and other surface water and groundwater sources. The model was calibrated and validated against actual data to verify simulation of reality as closely as possible. The model was calibrated and validated utilizing Hillsborough County EPC and Tampa Oceanographic Project ("TOP") salinity data. Physical Oceanographic Real Time System ("PORTS") and TOP data on current flow velocity and water levels were utilized to calibrate and validate water levels and current. The acoustic doppler current profilers used in the model study are able to measure the speed at which the water is traveling and the direction at various levels above the bottom within the water column. The TBD far-field model very accurately reproduces the observed tidal residual velocities observed with the acoustic doppler current profilers. The far-field model reflects any stratification that would occur during the model simulations. The far-field model simulates recirculation that occurs between the discharge and intake water. Recirculation is small due to the model's use of the actual bathymetry of Tampa Bay. There are significant shoals and other features that separate the water from the discharge and the intake canal that preclude significant recirculation most of the time. After submitting the far-field model report to DEP, further study was performed on the far-field model that calculated residence time for Tampa Bay. One study dealt with "residence" or "flushing" time. The concept of "residence time" is not well-defined; put another way, there are many different accepted ways of defining it. It may be defined in a simplified manner as the time it takes a patch of dye to flush out of the bay. However, for purposes of the studies performed on the far-field model, theoretical "particles" in model grids were tracked, and "residence time" was defined as the time it would take for the number of particles initially in a grid cell to decrease to 34 percent of the initial number. Using this approach and definition, residence time in the vicinity of the Big Bend facility on the south side where the discharge canal is located was less than 30 days. Immediately offshore of the area of the discharge, the residence time reduced to less than 15 days. The study indicated that the area of the Big Bend facility has a relatively low residence time. In the model's baseline run (for the desalination plant impacts only), maximum differences in salinity occurred during the month of April 1991. Throughout the two-year time period, the maximum concentration of salinities did not increase from this point, and in fact decreased. The maximum average value for salinity difference is 1.3 ppt at the grid cell located directly at the mouth of the TEC Big Bend discharge canal. More than two grid boxes away in any direction and the value falls to less than 0.5 ppt increase in salinity. The maximum salinity of any given day for the far- field model was in the range of 2.1 to 2.2 ppt, which compares favorably with the DHI near-field model which showed an increase of 2.5 ppt. The salinity changes caused by the cumulative effects scenario are smaller than the natural variability during the wetter months in Hillsborough Bay in cells immediately adjacent to the concentrate discharge. Increases in salinity will occur in the vicinity of the discharge canal but will be very localized and small relative to the natural variability in salinity observed in Tampa Bay. At a distance of more than a few hundred meters from the mouth of the discharge canal, it would be difficult (if not impossible) to determine statistically that there would be any increase in salinity from the desalination concentrate discharge. Over the two years modeled, there is no trend of increasing salinity. No long-term accumulation of salt is evidenced within the model. Further, no physical mechanism exists within the real world that would allow for such a long- term accumulation of salinity in Tampa Bay. Dr. Blumberg's independent work verified the conclusions in the far-field model constructed by USF. Dr. Blumberg's estimated flushing times are consistent with those found in the far-field model. DHI Near-Field Model The TBD near-field model was prepared by DHI. DHI prepared a three-dimensional near-field model to describe the potential salinity impacts from the discharge of the proposed desalination plant. The DHI model is a state-of-the-art model whose physics are well documented. By model standards, the DHI near-field model is a high resolution model. The DHI model essentially "nests" within TBD's far-field model. The near-field area includes those areas that would be directly influenced by the combined power and desalination discharges, the North Apollo Embayment and the residential canal system adjacent to the discharge canal. The near-field model was designed to determine whether or not the desalination plant would cause continuous increases in salinity and to predict any increase in salinity in the North Apollo Embayment and the associated canal system. In addition, DHI evaluated the potential for saline recirculation between the discharge and the intake via short circuiting due to overtopping of the existing break water. In order to construct the near-field model, existing data on bathymetry, wind sources, meteorology and other parameters were examined and analyzed. In addition, the information from an intensive data collection effort by Mote Marine Laboratories on current velocities, temperatures, and salinities was incorporated into the model. TBD conducted bathymetric surveys in the residential canal areas, the North Apollo Embayment, and the area between the discharge canal and the intake canal. The model has a vertical structure of six grids and reflects vertical stratification that would occur in the system being modeled. The vertical grids in the model can detect a thermal plume one meter in depth (the size of the thermal plume from TEC's discharge). Information about the TEC thermal plume was incorporated into the model and utilized to calibrate the model's predictive capabilities. The model took into account interactions between the temperature plume and the salinity plume. The model predictions matched the measured temperature plume created by the TEC discharges quite well. The near-field model conservatively assumed a scenario in which only the two TEC units with the smallest total through-flow of 691.2 million gallons a day cooling water were active. DHI then assumed production of a maximum 29 mgd in product water. A salinity level of 32.3 ppt at the intake was utilized in the simulation. The model assumed a conservative wind condition which results in less mixing and dispersion of the plume. Further, wind direction tended to be from the southwest or west during the simulation, which tends to push the plume against the TEC break water which tends to reinforce recirculation. SOBAC witness Dr. Parsons agreed that these simulations for April and May 2000 constituted extreme conditions. DHI ran its model for a total time period of six weeks. The "warm up" for the simulation took place from April 15 to May 7, followed by the "calibration" simulation from May 8 to May 22. An additional validation sequence was run from May 25 to June 8. The production run was defined as the three weeks from May 8 to May 29, 2000. The intensity of the calculations performed in the near-field model due to its high spacial resolution and numeric restrictions make it computationally demanding. The calibration runs took approximately a week to 10 days to run on a state-of-the-art computer. From a computational standpoint, it is not practical to run the near-field model for a two-year time period. The model shows good agreement between its water levels and current velocity to observed data. The model reflects the recirculation of the discharge water that would occur in the system. The maximum salinity for the extreme case scenario in the near-field model is an increase in salinity of 2.5 ppt. With three condensers running, under the modeling scenario comparing the base condition to the desal discharge, there is a maximum difference of only 2.0 ppt. Further, there is no indication of any continuous build up of salinity in the near- field area due to the desalination plant discharge. DHI performed many sensitivity runs on the model, including one which examined rainfall conditions. The results of a two-inch rainfall analysis show that rainfall profoundly freshens the water in the near-field area. Since the modeling was done in a time period of extreme drought, with no freshwater inputs, the ambient or background salinity trended up over the time frame of May through June. As with any estuary, if freshwater inflow is removed, the estuary will get saltier until freshening occurs. Even with the model simulation period extended an additional 10 days beyond that reflected in TBD Ex. 1-O, the model results did not show any increase of salinity differences caused by the desal facility above 2.5 ppt. Based on data from field collections, the operation of the desal plant under worst case conditions did not exceed the assimilative capacity of the near-field environment. A 10 percent salinity change (3.23 ppt) was not reached in any grid cell. The Blumberg Study The "Environmental Impact Assessment for a Seawater Desalination Facility Proposed for Co-Location with the Tampa Electric Company Big Bend Power Generation Facility Located on Tampa Bay, Florida" authored by Norman Blake and Alan F. Blumberg ("Blumberg Study") is a hydrodynamic model study combined with an analysis of potential biological effects. The Blumberg Study was performed at the request of and presented to the Board of County Commissioners of Hillsborough County, Florida. Dr. Blumberg's model used 1998 and 1999 as its baseline, which consisted of an extremely wet year followed by an extremely dry year. The model assumed a scenario of two cooling units in operation pumping 656 mgd of discharge flow. The results of the Blumberg Study are very similar to the results of TBD's far-field model. In addition, the model ran for a 9-year period without any sign of ongoing build-up of salinity. After the two-year model run, the second year ran for an additional 7 simulated years for total model simulation period of 9 years. The Blumberg Study found salinity only increased by 1.4 ppt in the North Apollo Beach Embayment. In fact, the Blumberg Study showed no salinity build-up after the second year of the 7-year portion of the model simulation. The Blumberg Study found that the flushing time for the area near the Big Bend facility ranges from 4 to 10 days. The Blumberg Study applied a formula to predict potential DO saturation level changes. The analysis concluded a small change to DO saturation assuming full saturation on average of 7 mg/l. The Blumberg Study predicted that the desalination discharge would not lower actual DO levels below 5 mg/l. The Blumberg Study concluded that the marine ecology will not be affected by the desalination facility operation. Older Two-Dimensional Models of Tampa Bay Significant strides have been made in hydrodynamic modeling over the last 10 years, with the standard changing from two-dimensional models to three-dimensional models. Three-dimensional models provide more complete results than two-dimensional models. In the late 1970's through the late 1980's, modeling was constrained by the computing limitations of the time and could not examine the difference in water layers in a bay and potentials for currents going in different directions or speeds in different layers of the bay, as now done by state-of-the-art three-dimensional models. A two-dimensional model cannot accurately represent the tidal residual circulation in an estuary such as Tampa Bay, because it omits some of the critical physical forces that drive this type of flow. As the acoustic doppler current profiler showed, water flows in the top of the water column in one direction and flows in the bottom of the water column in a different direction. A two-dimensional model would average these flows over the entire vertical water column. In doing so, it would show much slower residual flow (and, therefore, longer residence time and a longer time to flush the system). SOBAC offered the testimony of Dr. Carl Goodwin, a civil engineer with the USGS. Dr. Goodwin provided testimony on two-dimensional model studies he did for the USGS in the late 1980's to assess the effects of dredging the shipping channel in Tampa Bay. Dr. Goodwin's studies, contained in SOBAC Exs. 69 and 70, suggested the existence of "gyres" in Tampa Bay. But no "gyres" have been observed, and it now appears that these gyres actually do not exist but are two- dimensional modeling artifacts, as shown by state-of-the-art three-dimensional modeling of Tampa Bay. In an earlier version of Dr. Luther's Tampa Bay model, an experiment was performed running the model in a vertically average mode to mimic the two-dimensional model. In this mode, the model was able to reproduce the "gyres" that Dr. Goodwin observed in his two- dimensional model. When the physical equations that related to pressure forces (baroclines) were reactivated in the three- dimensional model, the "gyres" disappeared. In addition, this experiment showed that the two- dimensional model simulation showed residence times an order of magnitude longer as compared to the full three-dimensional simulation. This means that residence time would be 10 times longer in the two-dimensional model than in the three- dimensional model, which takes into account baroclinic forces. Subsequent to the publication of his modeling studies (SOBAC Exs. 69 and 70), Dr. Goodwin found that it would take approximately 110 days for water to travel from the mouth of the Hillsborough Bay to the mouth of Tampa Bay in 1985. This calculation by Dr. Goodwin was not subjected to peer review or the USGS process. However, dividing the 110-day time period with correction factor of 10 discussed above, Dr. Goodwin's corrected estimate would predict an 11-day period for transport of water from Hillsborough Bay to the mouth of Tampa Bay--similar to the Blumberg Study and far-field model results. Opinions of Other SOBAC Experts Besides Dr. Goodwin, SOBAC also elicited some general opinions regarding the combined thermal and salinity plume from Dr. Mike Champ, called as an expert in the areas of environmental biology and chemistry, and from Dr. Wayne Isphording, called as an expert in sedimentology and geochemistry. In part, Dr. Champ based his opinion on a misunderstanding that Tampa Bay is not well-mixed or well- circulated at the location of the Big Bend power plant. In this respect, Dr. Champ's testimony was contrary to all the evidence. Even the "gyres" suggested by Dr. Goodwin's two- dimensional model studies would suggest a great deal of mixing in Middle Tampa Bay in the vicinity of the Big Bend plant. To the extent that the opinions of Dr. Champ and Dr. Isphording differed from the modeling results, they are rejected as being far less persuasive than the expert opinions of the modelers called by TBD, who spent far more time and effort studying the issue. Compliance with Dissolved Oxygen Standard Oxygen is a gas which can dissolve in water to some degree. There are two measurements of DO in water: saturation point and actual level. The saturation point of DO in water equates to the maximum amount of DO that water will hold. The actual level of DO is a measurement of the oxygen in the water. Since the saturation point is the maximum amount of DO that water will hold in equilibrium, the actual level of DO in water is typically equal to or lower than the saturation point. Desalination will affect the saturation point of DO to the extent that it increases salinity. Increased salinity decreases the saturation point of DO because it lowers the potential for water to hold oxygen. But desalination would not affect the actual level of DO in the water if the saturation point remains above the actual level of DO in the water. TBD determined that in the worst case scenario using undiluted desalination discharge, the lowest possible saturation point of DO would be 5.7 mg/l. If the actual level of DO is above 5.7 mg/l, desalination may lower that actual level of DO to 5.7 mg/l. If the actual level of DO is below 5.7 mg/l, desalination will not lower the DO. Since TBD will aerate the water in the pretreatment process, if the actual level of DO is below 5.7 mg/l, the actual level of DO in the discharge water will be increased. The permit DEP proposes to issue to TBD requires that DO at the point of discharge from the RO plant meet the following: that instantaneous DO readings not depress the intake DO when intake DO is at or below 4.0 mg/l, and that they be greater than or equal to 4.0 mg/l when intake DO is greater than 4.0 mg/l; that 24-hour average readings not depress the 24-hour average intake DO when the 24-hour average intake DO is at or below 5.0 mg/l, and that they be greater than or equal to 5.0 mg/l when the 24-hour average intake DO is greater than 5.0 mg/l. The evidentiary basis for SOBAC's argument that the proposed permit's DO limitation allowed violations of state water quality standards was the testimony of Dr. Champ. But it was evident from his testimony that Dr. Champ was not even aware of the effluent limitations until they were pointed out to him at final hearing. Nonetheless, and although Dr. Champ barely had time to read the DO limitations, Dr. Champ immediately opined that the proposed DO limitations virtually invited water quality violations. He dismissed the permit language out-of-hand as being "loosey-goosey," "fuzzy-wuzzy," and "weasel-like." Actually, there is no conflict between the proposed permit's DO limitations and the water quality standards and water quality criteria in DEP's rules. Other witnesses, particularly Tim Parker of DEP, properly compared the language in the permit with DEP's rules containing water quality standards and water quality criteria. Mr. Parker pointed out that the rules must be read in harmony with each other. Rule 62-302.530(31) contains DO water quality criteria and requires that the "actual DO shall not average less than 5.0 in a 24 hour period and shall never be less than 4.0." Rule 62-302.300(15), a water quality standard, states: Pollution which causes or contributes to new violations of water quality standards or to continuation of existing violations is harmful to the waters of this State and shall not be allowed. Waters having a water quality below the criteria established for them shall be protected and enhanced. However, the Department shall not strive to abate natural conditions. Mr. Parker testified that the "natural conditions" referred to in Rule 62-302.300(15) are those found in the intake water to the desalination facility. TBD will not violate either the water quality criteria or the water quality standard for DO. If the actual level of DO in the intake water is less than 5.0 mg/l, TBD will not decrease the actual level of DO in the water below 5.0 mg/l because the actual level of DO is below the worst case saturation point of 5.7 mg/l. The water quality standard in Rule 62-302.300(15) does not prohibit discharges having DO levels below 4.0 mg/l when that discharge does not cause or contribute to existing DO violations. TBD will not cause or contribute to existing DO violations because if the level of DO in the intake water which is the natural condition is less than 4.0 mg/l, TBD will not decrease the actual level of DO in the water. To the contrary, the desalination process will increase the actual level of DO whenever it is below 5.0 mg/l. TBD has provided reasonable assurance that the proposed desalination discharge will not violate the DO water quality standards and criteria in Rules 62-302.530(31) and 62- 302.300(15) because the desalination process will not decrease the actual level of DO below 5.0 mg/l. SOBAC argued that DO levels will drop between intake and discharge as a result of desalination. Some of this argument was based on the testimony of Dr. Mike Champ, one of SOBAC's expert witnesses. But Dr. Champ's testimony on this point (and several others) is rejected as being far less persuasive than the testimony of the expert witnesses for TBD and the other parties. See Finding 196, infra. SOBAC's argument apparently also was based on a fundamental misapprehension of the results of the Blumberg Study, which SOBAC cited as additional support for its argument that desalination will decrease DO at the discharge point. The Blumberg Study only spoke to desalination's effect on DO saturation concentrations, not to its effect on actual DO levels. (In addition, contrary to SOBAC's assertions, the Blumberg Study did not model DO saturation concentrations but only inferred them.) pH The pilot plant measured and analyzed the potential for pH changes in the desalination process and demonstrated that the desalination process reduced pH by no more than a tenth of a pH unit. pH ranges in natural seawater from top to bottom change over one full pH unit; a tenth of a pH unit change would be well within the natural variation of the system. TBD has provided reasonable assurances that the proposed desalination discharge will not violate Rule 62- 302.530(52)(c), which requires that pH shall not vary more than one unit above or below natural background of coastal waters, provided that the pH is not lowered to less than 6.5 units or raised above 8.5 units. Limitations for pH in the permit ensure compliance with Rule 62-302.530(52)(c) at the point of discharge to waters of the state. Temperature Nothing in the desalination process adds heat to the discharged water. To the contrary, the desalination process may dissipate heat due to the interface of the intake water with the air surface in the pretreatment process. Further, the effect of removing 25 mgd of heated cooling water as desal product water reduces the heat load coming out of the TEC plant cooling water discharge by that same 25 mgd. Temperature readings taken as part of the pilot plant study confirm a slight decrease in temperature across the desalination process. Metals The pretreatment process employed by TBD will result in a reduction in metals in the treated water. Ferric sulfate is added to the intake water upstream of the sand filters in the pretreatment process to precipitate metals into solid material which can be captured by the sand filters. Adding ferric sulfate in the pretreatment process results in a net reduction in the total mass load of metals in the discharge water. Initial calculations in the permit application that 104 pounds of ferric sulfate were being discharged in the desalination concentrate were based on using 20 mg/l of ferric sulfate and a conservative estimate of 95 percent settling of solids, with 5 percent of the ferric sulfate being discharged in the desalination concentrate. Further testing through the pilot plant revealed that coagulation optimizes at 9 to 14 mg/l of ferric sulfate with 97.5 percent of the solids settling, resulting in only 2.5 percent (52 pounds) of the ferric sulfate being discharged per day. The desal facility discharge of iron is minute in comparison to naturally occurring metals within the surface water flowing into Tampa Bay from the Hillsborough and Alafia Rivers. Increases in iron due to ferric sulfate addition are predicted to result in a diluted discharge in which the iron level is still below Class III marine surface water limitation of 0.30 mg/l. Even SOBAC witness Dr. Isphording confirmed that there are no concerns caused by metals that TBD is adding during the process. Discharge Effect on Metal Absorption/Desorption Dr. Isphording limited his concerns to the reaction of higher salinity, DO, and redox to the sediments already contained within the area beyond the discharge point. Dr. Isphording admits that he cannot quantify what the potential release of heavy metals would be due to these factors. Absorption of metals occurs when an organic or clay particle attracts to its surface a metal. Biota do not obtain metals if the metal is held in sand or silt size particles. Biota, be they plant or animal, in most cases obtain the metals they receive from tiny particles that are suspended in the water called microparticulate material. Microparticulate material is generally referred to as colloidal phase. Typically, this phase is on the order of a tenth of a micron in size. Biota obtain metals only if they are present at clay- size particles. Only 10 percent of the quantity of metals that are theoretically available to the biota in a given environment is actually absorbed in tissues. Salinity Has Little Effect on Metals Salinity does not exert a controlling influence on absorption/desorption reactions except at very low salinities. If the salinity is zero, which is essentially a pure freshwater environment, and the salinity level then rises 3 ppt, there would be profound changes in the metal loads, for example, where rivers meet estuaries or seawater. When salinity levels in the water are on the order of 25 ppt, small salinity perturbations such as 2.5 ppt will have a very small effect on absorption/desorption reactions. In fact, the influence can be either positive or negative, but in general they are going to be quite small. Potential releases or gains of metal from salinity changes of 2.5 ppt, at the area of the discharge canal, would be difficult to predict, and it is uncertain whether the change would be positive or negative. pH Will Have Virtually No Effect on Metals Although SOBAC witness Dr. Isphording knew of no change to pH caused by the desalination process, he testified to the alleged effect of lowered pH on the metal in the sediments and water column. Only large pH differences can have a significant influence on absorption or desorption of metals. Any effect on absorption from a decrease in pH on the order of a tenth of a pH unit will be hidden within the natural variations of the estuarine system. See Finding 140, supra. Effect of Lower Oxygen Levels on Metals Redox is basically an oxidation-reduction phenomenon. In order for the low levels of oxygen to have a reducing effect resulting in a release of metals from sediments, virtually all of the oxygen would have to be removed from the water. Basically, the environment would have to reach anoxic conditions. Even then, some metals such as copper would remain within the sediments. In an oxygen-buffered system, redox perturbations will not significantly or measurably mobilize metals. Sediments can be oxidizing in the upper part and then generally become more reducing at depth. The area near the desal discharge does not have organic-rich deep sediment. Proposed Discharge Effect on Bioavailability of Metals The proposed desalination plant's discharge will not increase the bioavailability on metals above that of natural variations and any changes would be hard to discern or measure. Nor will there be any appreciable accumulation of metals in sediments in the receiving water resulting from the proposed desalination discharge. DEP has not established any sediment quality standard and monitoring of sediments is not a NPDES requirement. The desalination plant does not result in violations of Class III marine surface water criteria and standards. No Synergistic Effects Caused by Discharge There are no synergistic effects from the proposed discharge wherein the combination of two elements such as temperature and salinity together would create a new effect. Instead, pH, redox, salinity, and temperature may have small, immeasurable effects that may offset each other. No Adverse Impacts to Biota Comprehensive species lists of phytoplankton, zooplankton, benthic macroinvertebrates, fish, aquatic flora (including seagrasses and mangrove species), and threatened or endangered species inhabiting the area were prepared based on extensive review of applicable scientific literature on Tampa Bay. The salinity tolerance ranges of these species were determined through extensive review of information on salinity ranges associated with species capture, laboratory studies, review of studies addressing species types and salinity tolerances in hypersaline estuaries, and species salinity tolerances determined for other desalination projects. When background salinity is above 10 ppt, changes in salinity of a few ppt have no effect on most organisms. Lower salinities are more detrimental than high salinities to most marine organisms, as long as the upper limit does not exceed a value of approximately 40 ppt salinity. Most planktonic species and life forms can tolerate salinities of up to 40 ppt. Mangrove and seagrass species living in the area can tolerate salinity levels as high as 60 ppt. Benthic macroinvertebrates in the area routinely experience, tolerate and survive in salinity levels ranging from approximately 6 ppt to over 39 ppt under natural environmental conditions. Fish species in the area routinely experience and tolerate salinity levels as high as 39 to 40 ppt under natural environmental conditions. Estuaries serve as fish nurseries because fish species lay their eggs in estuaries, and the larval and juvenile life stages live and mature in estuaries. Due to extreme range of conditions that naturally occur in estuaries, fish reproductive strategies have adapted to enable fish eggs and larval and juvenile life stages to tolerate the wide range of natural conditions, including ranges in salinity levels, that are endemic to estuaries. Egg, larval, and juvenile fish stages may be better able to tolerate extreme range of salinities than adults life stages. A 2.5 ppt increase in salinity and the permitted maximum increase of 10 percent above the intake chloride level is within the range of tolerance and variability that seagrasses, mangrove species, benthic macroinvertebrates, biota, fishes, manatees, zooplanktonic and phytoplanktonic species, and other organisms and life forms living in Tampa Bay routinely encounter and tolerate in the natural environment. A 2.5 ppt increase in salinity with the maximum permitted salinity discharge limit of 35.8 ppt of salinity and the permitted maximum increase of 10 percent above the intake chloride level will not adversely affect the survival or propagation of seagrasses, mangroves, benthic macroinvertebrates, biota, zooplankton, phytoplankton, fish, fish eggs, or juvenile life stages of fish species, or other organisms or life forms in Tampa Bay, and specifically the portion of Tampa Bay in the vicinity of the desalination plant discharge. The Shannon-Weiner Index, which is a biological integrity index codified at Rule 62-302.530(11), requires that the index for benthic macroinvertebrates not be reduced to less than 75 percent of established background levels. Since there will be no adverse impacts to benthic macroinvertebrates due to the desalination discharge and since the level of salinity increases anticipated will tend to benefit benthic macroinvertebrates population, TBD has met the criterion in Rule 62-302.530(11). The Mote Marine Laboratory data showed that Tampa Bay experienced a 2.0 ppt change in salinity over the course of one month. No fish kill or observable die-offs of species were observed or reported from this natural occurrence of elevated salinity. The desalination discharge will (1) not adversely affect the conservation of fish and wildlife, including endangered species, or their habitats, (2) not adversely affect fishing or water-based recreational values or marine productivity in the vicinity of the proposed discharge, (3) not violate any Class III marine water quality standards, and (4) maintain water quality for the propagation or wildlife, fish, and other aquatic life. The desalination discharge meets the antidegradation standards and policy set forth in Rules 62-4.242 and 62- 302.300. Discharge Disposal Options Analyzed As part of the permitting process, TBD demonstrated that the use of land application of the discharge, other discharge locations, or reuse of the discharge was not economically and technologically reasonable, pursuant to Rule 62-4.242. TBD submitted a sufficient analysis of these options as part of its Antidegradation Analysis. (TBD Ex. 1G; TBD Ex. 200, Fact Sheet, p. 16). Further Protection in the Permit The permit review of the desalination permit application is one of the most thorough ever conducted by DEP. The proposed permit has conditions which create and provide a wide margin of environmental protection. The permit sets effluent limitations of various constituents which are reasonably expected to be in the desal facility discharge and provides for monitoring programs to ensure compliance with those effluent limitations. The monitoring requirements of the proposed permit exceed the monitoring requirement imposed on other facilities in the Tampa Bay area. Effluent Limitations DEP established effluent limitations using the Class III marine state water quality standards, data provided from the pilot plant regarding the chemical characterization, the modeling conducted by DHI and the University of South Florida, and the water quality data collection by Mote Marine Laboratory in connection with the establishment of the WQBEL. The effluent limitations contained in the permit are consistent with DEP rules. The proposed permit restricts TBD to the lesser of either the chloride limit of 10 percent above intake or the salinity limit of 35.8 ppt. There is no state water quality standard for salinity. The permit limit for chlorides complies with Rule 62- 302.530(18). The permit's additional requirement of a minimum dilution ratio has the effect of limiting chlorides to 7 percent above intake for 384 hours per year and 5 percent above intake for the remainder of the year and thus provides extraordinary assurance that the state water quality standard for chlorides will be met. Dr. Champ was SOBAC's primary witness in support of its argument that the proposed permit allows a discharge with excessive salinity. But it was apparent from his testimony that Dr. Champ misinterpreted the permit limitations for salinity. See Finding 196, infra. Dr. Champ conceded that the chloride limit of 10 percent above intake was appropriate but focused on the 35.8 ppt maximum, as if it overrode the chloride limitation. As found, the opposite is true. TBD will be limited to 10 percent above intake for chlorides even if the result is salinity far less than the daily maximum of 35.8 ppt. Dr. Champ also had concerns about comparing the discharge to intake chloride levels as not being representative of "normal background." He argued (as does SOBAC) for comparing discharge to chloride levels somewhere else in Middle Tampa Bay, nearby but far enough away to insure no influence from the discharge. But the modeling evidence provided reasonable assurance that there will not be a great deal of recirculation of discharge to intake and that the recirculation expected will not cause salinity to build-up continuously over time. The modeling evidence is accepted as far more persuasive than Dr. Champ's testimony. See Finding 196, infra. The only metals for which effluent limitations were established in the permit are copper, nickel, and iron because these were the only metals determined to be close to the state water quality standard levels by the pilot plant studies. The actual levels of such metals in the desalination discharge will be less than those in the pilot plant testing because the dilution ratio (12.8 to 1) used in the pilot testing is much higher than the minimum dilution ratio required by the permit (20 to 1). The permit effluent limitations for copper, nickel, and iron are based on, and comply with, DEP Rules 62- 302.500(2)(d) and 62-302.530(24), (39) and (45). The permit effluent limitations for Gross Alpha are based on and comply with the requirements in Rule 62- 302.530(58). Biological treatment of the desalination plant discharge concentrate is not required because it consists of seawater. Monitoring for Effluent Limitations DEP is able to separately determine TEC's compliance with its permit from TBD's compliance with the effluent limitations in the proposed desalination permit because of how the facility is designed and the monitoring is constructed. Monitoring requirements in the proposed permit were determined with reference to the probability of desal facility discharge exceeding specific water quality standards. DEP rules do not require monitoring for each and every constituent detected above background concentrations, only those which would probably exceed state water quality standards. The permit requires monitoring of effluent limitations at the intake to and discharge from the desalination facility and the calculation of the diluted effluent levels in the co-mingled discharge water. In order to calculate the effluent components in the diluted discharge water, continuous monitoring is performed on the TEC cooling water discharge rate of flow. Parameters of DO, conductivity, salinity, chlorides, copper, iron, nickel, radium, gross alpha, and effluent toxicity are measured at both intake and discharge pursuant to proposed permit. Monitoring of Intake Monitoring of the intake will be located, after interception off TEC Units 3 and 4, prior to entering the desalination plant. Using a sampling location of the intake to the desalination facility prior to filtering or chemical addition for background samples is consistent with the definition of "background" in DEP Rule 62-302.200(3). EPC Stations 11, 80, 81, 13, and 14 are not proper locations for background samples because salinity varies with tides and depth and those stations are too distant from the actual intake point. EPC station 9 is not a good location because it is closer to the discharge than the permit sample point. Monitoring of Discharge Monitoring of the discharge will take place in the wet well prior to discharge into TEC's cooling water discharge tunnels. This monitoring location is in compliance with Rule 62-620.620(2)(i) which provides for monitoring of effluent limitations in internal waste streams. Monitoring of the desal facility discharge concentrate in each of the four cooling water discharge tunnels is impractical due to the high volume of dilution and addition of four potential discharge locations. Once the desal facility concentrate is diluted by the TEC cooling water discharge, it is much more difficult to obtain accurate water quality testing for constituents at such minute levels. Monitoring of the Combined Discharge Concentrations Calculations determine the mixing ratios of the desalination concentrate with TEC's cooling water. Using the flow data from TEC, the calculations will accurately determine the water quality of the co-mingled discharge water. Compliance with Permit Effluent Limitations The proposed permit requires TBD to monitor constituents for which there are effluent limitations on either a daily, weekly or monthly basis, depending on the constituent. The frequency of monitoring for each constituent is based on comparing the expected levels of the constituent to the water quality standard and analyzing the probability of the desal facility discharge exceeding that standard. The monitoring provides additional assurances beyond the pilot plant studies, testing and modeling that no water quality standard will be violated. Continuous monitoring is not necessary to successfully monitor discharges. Monthly measurements are sufficient to determine compliance even for a daily permit level because the chemical characterization studies provide reasonable assurances that the desalination concentrate will not exceed the effluent limitations. Monthly monitoring provides further checks and balances to assure that the desalination discharge is in conformance with the effluent limitations and DEP rules. The EPA only requires that monitoring occur at least once a year. Conductivity provides a direct correlation to salinity and chlorides. Measuring conductivity provides salinity and chloride levels by basis of calculations and is typically used as a surrogate for monitoring chloride and salinity continuously. Salinity and chloride cannot themselves be measured continuously because they are measured by lab tests. The permit requires conductivity to be monitored continuously, not because DEP believed the desalination discharge would be near the chloride limitation, but rather to be extremely conservative. The permit conditions treat an exceedance of salinity or chlorides based on conductivity readings to be a violation of the permit effluent limitations for salinity and chlorides. TBD provided reasonable assurance to DEP that the proposed desalination discharge would not violate the DO water quality standards and criteria in Rules 62-302.530(31) and 62- 302.300(15). The permit condition requiring monitoring of DO provides verification that desal facility discharge will meet the DO water quality standards. Even SOBAC's witness Dr. Champ admitted that a continuous measurement for DO is not as valuable as random weekly samples. External Monitoring Programs The proposed permit requires TBD to develop and submit to DEP a Biological Monitoring Program to monitor seagrasses, benthic macroninvertebrates and fish populations to be consistent with existing Tampa Bay monitoring programs. This program will provide an effective means of monitoring the potential impacts of the desalination discharge. The proposed permit also requires TBD to implement a Water Quality Monitoring Program for three monitoring stations located proximal to the intake, the discharge and the North Apollo Beach Embayment which will monitor conductivity, salinity, DO and temperature continuously. These monitoring programs will provide additional ambient data to DEP. If the data indicate an exceedance or reasonable potential for an exceedance of water quality standards, DEP may reopen the permit in accordance with the reopener clause contained in the permit. These monitoring programs go beyond the requirements in DEP rules. Additionally, DEP does independent monitoring of NPDES discharges without notice and on a purposely unpredictable basis. Proof of Financial Responsibility Rule 62-620.301(6) addresses when DEP may require a permit applicant to submit proof of financial responsibility to guarantee compliance with Chapter 403, Florida Statutes. TBD's compliance history was taken into consideration during the permitting process. Adequate financial assurance were provided in the permit application. (TBD Ex. 1I). Further, the permit conditions added by the settlement agreement (TBD Ex. 470) provide for additional financial assurance beyond those that can be required by the NPDES program and DEP rules. Additional Comment on SOBAC's Evidence As already indicated, SOBAC elicited the testimony of several expert witnesses at final hearing to support its contentions. But none of SOBAC's experts spent a great deal of time studying TBD's desal project, especially compared to witnesses for the other parties. Mostly, SOBAC experts expressed general scientific principles that were not directly tied to specifics of the desal project or were very general expressions of concern. Often, SOBAC's experts were not familiar with all the efforts of experts offered by the other parties to address those very concerns. Except for Dr. Champ, no SOBAC expert opined that the proposed permits would result in violations of DEP statutes and rules. Some SOBAC experts expressed opinions that only would be relevant if there were insufficient assurances in proposed permits that DEP statutes and rules would not be violated. Statistical evidence presented was not particularly relevant. Dr. Goodwin As previously mentioned, Dr. Carl Goodwin was willing to provide testimony on work he did for the USGS, but he gave no expert opinions on the permits which are the subject of these proceedings. As also previously discussed, his two- dimensional model studies were constrained by computational limitations. Even so, his studies indicated that flushing in Tampa Bay was becoming more rapid in recent years. In addition, even if the "gyres" suggested by his two-dimensional studies actually existed, they would tend to promote mixing in Tampa Bay in area of the Big Bend power plant. Dr. Champ Dr. Champ's first opinion was that 35.8 ppt is too high a salinity limit and would result in "oceanic" conditions. He attempted to compare this result to results of diversion of substantial amounts of freshwater inputs to the Black Sea for agricultural purposes--a totally different situation not suitable for comparison to Tampa Bay. Initially, Dr. Champ suggested a limitation of a 10 percent increase above "background" or "ambient" conditions; it was apparent that initially Dr. Champ was not cognizant of the 10 percent over intake chloride limitation in the proposed permit. When he was made aware of the chloride limit, he misinterpreted the two limits, saying that TBD would not be limited to the lower of the two. When it was suggested that he might have misinterpreted the two salinity limits, Dr. Champ testified that chlorides should be compared to a "natural" or "environmental" control site somewhere nearby but outside the influence of the combined TEC/TBD discharge; he said it was a "farce" to compare chlorides to a control site "inside the plant." In so doing, he seemed not to recognize the purpose of the comparison made in the proposed permit--to isolate and identify the impacts of TBD's desal process. In addition, dismissing without much consideration the contrary results of extensive and sophisticated modeling, Dr. Champ opined off- handedly that DO would decrease due to higher salinity that would recirculate and build-up over time. In part, Dr. Champ based this opinion on his misunderstanding that Tampa Bay is not well-mixed or well-circulated at the location of the Big Bend power plant. This was contrary to all the evidence; even if the "gyres" predicted by Dr. Goodwin's two-dimensional model existed, they would suggest a great deal of mixing in Middle Tampa Bay in the vicinity of the Big Bend plant. Dr. Champ next misinterpreted the DO limits in the proposed permit. See Finding 133, supra. Dr. Champ then predicted a decrease in species diversity as a result of higher salinity and lower DO. (To the contrary, salinity increases in the amounts predicted by the far greater weight of the evidence probably would result in somewhat of an increase in species diversity.) Ultimately, Dr. Champ testified that consequences to marine organisms would be dire, even if salinity increased only by 2.5 ppt, because a "salinity barrier" would form across Middle Tampa Bay in contrast to more gradual natural changes in salinity. The far greater weight of the evidence was to the contrary. Dr. Champ made several suggestions to avoid the calamitous results he predicted: require use of a cooling tower to reduce the temperature of the combined TEC/TBD discharge; collect the desal brine concentrate and barge it to the Gulf of Mexico; require intake and discharge pipes extending into the shipping channel in Middle Tampa Bay. But Dr. Champ did not study or give a great deal of thought to implementation of these suggestions. Besides, the other parties proved that these measures were not needed for reasonable assurances. In an attempt to buttress his opinion testimony, Dr. Champ also testified (along with SOBAC's President, B.J. Lower) that the TEC intake canal is virtually devoid of life and that biodiversity in the discharge canal is very low. This testimony was conclusively refuted by the rebuttal testimony of Charles Courtney, who made a site visit after SOBAC's testimony and described in detail a significant number of healthy species in the intake canal, including oyster communities, xanthid crabs, porcellanid crabs, snook, anemones, bivalves, polychaete, and mangroves with seedlings. Of the one and one- half pounds of oysters that Mr. Courtney sampled, he estimated that approximately fifty percent of those oysters were living, which represents a very healthy community. Mr. Courtney further noted that some of the crabs were carrying eggs, which indicates an active life cycle for those species. As to the TEC permit modification, Dr. Champ testified that it was “in-house stuff” which would not affect the environment outside the TEC plant. No other SOBAC witness addressed the TEC permit modification. Dr. Isphording SOBAC called Dr. Wayne Isphording as an expert in sedimentology and geochemistry. Dr. Isphording expressed no concern that the desal process would add metals to Tampa Bay. Essentially, he gave opinion testimony concerning general principles of sedimentology and geochemistry. He testified that heavy metals bound in sediments are released naturally with increases in salinity, but that salinity levels would have to be extreme to result in the release of abnormal quantities of such metals. He admitted that he had performed no studies of sediments in Tampa Bay and declined to offer specific opinions that metals in fact would be released as a result of predicted salinity increases. Dr. Isphording admitted that he knew of no condition in the proposed Desal Facility permit which would cause or allow a violation of state water quality standards. He was aware of no statute or rule requiring more monitoring and testing than is required in the proposed permit. Dr. Parsons SOBAC offered the testimony of Dr. Arthur Rost Parsons, an assistant professor of oceanography at the Naval Postgraduate School, in an attempt to raise questions regarding the near-field and far-field modeling which were provided by TBD to DEP during the course of the permitting process. However, not only had Dr. Parsons not done any modeling in Tampa Bay himself, he was not provided numerous reports and clarifications relating to the studies he was called to critique. He only reviewed an interim report dated November 1, 2000, regarding the near-field model. Dr. Parsons testified that the DHI model used for the near-field study was an excellent shallow water model. He found nothing scientifically wrong with it and testified that the "physics and the model itself is . . . well–documented." Dr. Parsons also did not contradict the results of the DHI model. Instead, he noted that the modeling task was difficult and complex, he described some of the model's limitations, and he testified to things that could have been done to increase his confidence in the model results. One of Dr. Parson's suggestions was to run the model longer. But the evidence was that, due to the model's complexity and high computational demands, it would have been extremely expensive to run the model for longer periods of time. Another of Dr. Parson's suggestions was to use salinity data would be to use the information that the model itself generated with regard to salinity distributions instead of a homogeneous set of salinity data. Dr. Parsons was concerned that use of homogeneous salinity data would not reflect the effect of "double diffusion" of heat and salinity, which would result in sinking of the combined heat. But engineer Andrew Driscoll testified in rebuttal that the effects of "double diffusion" would cease once equilibrium was reached and would not result in a hypersaline plum sinking to the bottom. In addition, he testified that turbulent mixing from tide and wind would dominate over the effect of "double diffusion" at the molecular level so as to thoroughly mix the water, especially in the shallow North Apollo Beach Embayment. Dr. Parsons also suggested that the model be run for rainy season conditions to see if the effects of vertical stratification would increase. But even if vertical stratification increased as a result of rain, salinity also would be expected to decrease. The scenario modeled was "worst case." Dr. Parsons also suggested the use of a range of temperatures for the combined heat/salinity plume instead of an average temperature. However, he conceded that it was not inappropriate to use average temperature. Instead, he would have liked to have seen the model run for a range of temperatures to see if the model was sensitive to temperature differences so as to increase his confidence in the results. Dr. Parson's testimony focused on the near-field model. His only comment on the far-field model was that he thought it should have used the out-puts from the near-field model (as the near-field used the outputs). Scott Herber SOBAC offered no direct testimony on the impact of the Desal Facility discharge on seagrasses in Tampa Bay. The testimony of Steve Herber, a doctoral student at the Florida Institute of Technology, related to the vulnerability of seagrasses, in general, to changes in salinity. However, Mr. Herber had no specific knowledge of the seagrasses present in Tampa Bay and had not performed or reviewed any scientific studies upon which his opinion could be based. He reached no conclusions about the specific permits at issue in this proceeding, nor about the effect of the Desal Facility on seagrasses in Tampa Bay. In contrast to Mr. Herber, the testimony of TBD's expert, Robin Lewis, and SWFWMD's expert, Dr. David Tomasko, provided detailed information about the seagrasses located in Tampa Bay. Both have studied seagrasses in Tampa Bay for many years and have been involved in mapping seagrass distribution in a variety of bays and estuaries along the west coast of Florida. Dr. Tomasko criticized witnesses for SOBAC who attempted to draw conclusions about Tampa Bay based on studies of other bays and estuaries because each bay has unique characteristics that cannot be extrapolated from studies of other bays. Dr. Tomasko and Lewis testified that seagrasses in Tampa Bay are becoming more abundant, that dissolved oxygen levels are increasing, and that water clarity in Tampa Bay is also improving. Dr. Mishra Dr. Satya Mishra was called by SOBAC as an expert in statistics. He is not an expert in the discrete field of environmental statistics. He has never been involved in the development of a biological monitoring program and could not provide an opinion regarding what would be an adequate sample size for this permit. He essentially expressed the general opinions that for purposes of predictive statistical analysis: random sampling is preferred; statistical reliability increases with the number of samples; and 95 percent reliability is acceptable. Dr. Mishra performed no statistical analysis in this case and could not conclude that the sampling provided in the proposed permit would not be random. Ron Chandler Ron Chandler, a marketing representative for Yellow Springs Instrument Corporation (YSI), simply testified for SOBAC regarding the availability of certain types of continuous monitoring devices. He did not offer any opinions regarding whether or not reasonable assurance required continuous monitoring of any specific parameter or any monitoring different from or in addition to what is proposed in TBD's proposed permit. John Yoho SOBAC called John Yoho as a financial and insurance expert to criticize the terms of an agreement by TBD, TBW, and DEP to settle Hillsborough County's request for an administrative hearing (DOAH Case No. 01-1950). This agreement is contained in TBD Ex. 470. But Yoho admitted that he had no knowledge regarding what is required to obtain an NPDES permit in terms of financial assurances. He also indicated that none of his testimony should be understood as relating in any way to financial assurances required for such a permit to be issued. Alleged Improper Purpose The evidence did not prove that SOBAC participated in DOAH Case No. 01-2720 for an improper purpose--i.e., primarily to harass or to cause unnecessary delay or for frivolous purpose or to needlessly increase the cost of licensing or securing the approval of TEC's permit modification applications. To the contrary, the evidence was that SOBAC participated in this proceeding in an attempt to raise justifiable issues arising from the peculiarities of the relationship of TEC's permit modification application to TBD's permit application. Although SOBAC suffered adverse legal rulings that prevented it from pursuing many of the issues it sought to have adjudicated on TEC's permit modification application, it continued to pursue issues as to the TBD permit application which, if successful, could require action to be taken on property controlled by TEC and, arguably, could require further modification of TEC's permit.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Florida Department of Environmental Protection enter a final order: (1) issuing the proposed permit number FL0186813-001-IWIS, as set forth in TBD Ex. 203 with the addition of the two permit conditions specified in TBD Ex. 470; (2) issuing proposed permit modification number FL0000817-003-IWIS, as set forth in TBD Ex. 225; and (3) denying TEC's request for attorney's fees and costs from SOBAC under Section 120.595(1). Jurisdiction is reserved to enter an order on TBD's Motion for Sanctions filed on August 13, 2001, regarding SOBAC expert Ralph Huddleston. DONE AND ENTERED this 17th day of October, 2001, in Tallahassee, Leon County, Florida. __________________________________ J.

The Issue The issue for determination in this case is whether Florida Administrative Code Rule 62-302.300(6) is an invalid exercise of delegated legislative authority because the rule is vague, fails to establish adequate standards for agency decisions, or vests unbridled discretion in the agency.
Findings Of Fact The Parties The Department is the state agency authorized under Chapter 403, Florida Statutes, to regulate discharges of industrial wastewater to waters of the state. Under a delegation from the United States Environmental Protection Agency, the Department administers the National Pollution Discharge Elimination (NPDES) permitting program in Florida. The Department promulgated the rules in Florida Administrative Code Title 62 that are applicable to the permitting of wastewater discharges. FOPB is a non-profit Alabama corporation established in 1988 whose members are interested in protecting the water quality and natural resources of Perdido Bay. FOPB has approximately 450 members. About 90 percent of the members own property adjacent to Perdido Bay. James Lane is the president of FOPB. Jacqueline Lane and James Lane live on property adjacent to Perdido Bay. IP owns and operates a paper mill in Cantonment, Escambia County, Florida. IP is the applicant for the Department authorizations that are the subject of DOAH Case Nos. 08-3922 and 08-3923. Background When this rule challenge was filed, DOAH Cases Nos. 08-3922 and 08-3923 (the permit cases) involved challenges by these same Petitioners to four Department authorizations for IP: an NPDES permit, a Consent Order, an approved exemption for the experimental use of wetlands pursuant to Florida Administrative Code Rule 62-660.300, and a waiver related to the experimental use of wetlands. IP later withdrew its request for the experimental use of wetlands exemption and the related waiver. Petitioners were ordered to show cause why their claim regarding the invalidity of Florida Administrative Code Rule 62- 660.300 was not rendered moot by IP’s withdrawal of its request for the exemption. Subsequently, the challenge to the validity of Florida Administrative Code Rule 62-660.300 was dismissed as moot. At the commencement of the final hearing on June 22, 2009, FOPB and James Lane announced that they were withdrawing their rule challenges except with respect to Florida Administrative Code Rule 62-302.300(6), and that the only legal ground being asserted for the invalidity of the rule is that it is vague and vests unbridled authority in the Department. Petitioners’Standing Jacqueline Lane, James Lane and a substantial number of the members of FOPB swim, boat, and make other uses of Perdido Bay. Perdido Bay would be affected by IP's wastewater effluent. The challenged rule was applied by the Department to determine that IP's proposed industrial wastewater discharge was in the public interest. The Challenged Rule Florida Administrative Code Rule 62-302.300, is entitled "Findings, Intent, and Antidegradation Policy for Surface Water Quality." Subsection (6) of the rule states: Public interest shall not be construed to mean only those activities conducted solely to provide facilities or benefits to the general public. Private activities conducted for private purposes may also be in the public interest. Most of the permits that are issued by the Department are issued to private entities whose primary purposes are personal uses or the production of private incomes and profits, rather than solely to provide facilities or benefits to the general public.
The Issue The issues to be resolved in this proceeding concern whether the Petitioner has standing to bring this action and, therefore, whether the Intervenor has standing; whether the applicant has provided reasonable assurances of its entitlement to a construction permit for the facility; whether the applicant is precluded from availing itself of a separate biohazardous waste storage general permit through notification to the Department; whether the Petitioner is entitled to challenge the notice requirements of the general permit; and whether the facility to be permitted should be characterized as a biological waste incineration facility or a biohazardous waste treatment facility.
Findings Of Fact The Petitioner, Hamilton County Board of County Commissioners ("County"), is the governing body of Hamilton County, a political subdivision of the State of Florida. The operation of the political subdivision of Hamilton County is conducted by and through its duly-elected Board of County Commissioners. The County conducts a variety of official functions, including but not limited to, the levy and collection of taxes, construction and maintenance of county-owned buildings, roads, bridges and other facilities, the funding and maintenance of county recreational parks and related facilities, and the funding and operation of county health and welfare programs, as well as the regulation and disposal of solid waste and sewage. TSI is a Florida corporation organized to specialize in the construction and operation of incineration facilities, including biohazardous waste incineration facilities. The project sub judice is the first incinerator facility proposed for construction by TSI. The corporation and its directors, officers or operational personnel have not participated in the construction or operation of any type of incinerator facility in the past. DER is an agency of state government charged with the responsibility of regulating the quantity and quality of emissions from facilities such as the incinerators involved in the case at bar, and with reviewing applications for permits for the construction and operation of air pollution source facilities, including incinerators, as well as biohazardous waste disposal and treatment facilities and solid waste resource recovery and management facilities. Its reviewing responsibility is performed by weighing such permit applications against the yardsticks set forth in Chapter 403, Florida Statutues, and Rule Chapters 17-2, 17-4, 17-6, 17-701 and 17-712, F.A.C., which it employs to determine, among other parameters, whether a particular air pollution source facility can be reasonably assured to comport with the standards embodied in those rule chapters. The Intervenor, City of Jasper ("Jasper"), is a municipality located within Hamilton County, Florida. The Jasper Industrial Park is the site of the proposed biohazardous waste incinceration facility. That site is within the city limits of Jasper. Description of Facility and Process Incineration is the most commonly used procedure for treating medical waste. The combustion of waste is especially appropriate for hospital "redbag" waste, also known as medical waste. The combustion of medical waste destroys pathogens infectious materials and spores. TSI proposes to burn medical waste in two Basic Model 3500 biohazardous waste incinerators. The incinerators will be enclosed within a large building at the Jasper Industrial Park in Jasper, Florida. Each has a charging capacity of 35 tons per 24-hour day. The proper incineration of medical waste requires a residence time of one second in a secondary chamber, having a temperature of at least 1,800 degrees Fahrenheit. These time and temperature requirements will be achieved by the proposed Basic incinerator. The incinerator's loading door will not open until the secondary chamber temperature reaches 1,800 degrees Fahrenheit. Unlike other systems, the patented Basic incinerator system has three combustion zones in the incinerator, the main chamber, the secondary chamber, and the tertiary chamber. By means of these three stages, the Basic incinerator minimizes emissions of hydrocarbons, CO and nitrogen oxide. It is characterized by a "ram feeder" which allows the waste material to enter the incinerator through an air lock so as not to disturb control of the air within the furnace. It also has a "mechanical pulse hearth" which moves and tosses the burning material while moving it through the incinerator, shaking it up, much like logs in a fireplace. It thus mixes the waste material in the air for more complete combustion. Finally, a backhoe-type device digs the ashes out of the ash pit for disposal after combustion. The third stage of the Basic incinerator changes vapors coming from the main chamber to superheated gas. The "thermal exciters" in the third stage increase turbulence and mixing in this upper zone. With the addition of air in this third stage of burning, the gas burns like natural gas, thereby completely destroying the products of incomplete combustion from the previous stages. The gas will have a residence time of at least one second in the last combustion chamber, at no less than 1,800 degrees Fahrenheit, as required by Rule 17- 2.600(1)(d)4.A., F.A.C. The Basic incinerator is designed with an air lock door which prevents it from opening until the chamber temperature reaches the required 1,800 degrees Fahrenheit. This insures more complete combustion of waste and insures that the ignition of waste does not commence until the last combustion chamber temperature requirement of Rule 17-2.600(1)(d)4.D., F.A.C., is attained. After the tertiary stage, the gases resulting from combustion go to a heat recovery boiler system incorporating a heat exchanger involving water- filled tubes. The superheated gas flows past these heat exchanger tubes which reduce the gas temperature to approximately 250 degrees Fahrenheit. This serves to start condensing the HCL acid gas so that it will be amenable to reduction and conversion by the injection of finely-powdered lime on the way to the "baghouse" scrubber device. Additionally, at this stage, a portion of the superheated gases are recirculated to the combustion chamber for further exposure to combustion temperatures in order to achieve optimum burnout of all combustible materials. When the superheated gases reach the boiler-heat recovery, steam- generating device, they are at approximately 1,800 degrees Fahrenheit. In part, they consist of metallurgical fumes containing salts, oxides, heavy metals, leads and zincs. In order to prevent these salts from clogging the boiler, the cooling device reduces their temperature so that the oxides and metals form powders. Then if any of the resultant powder adheres to the boiler tubes, conventional coal-blowing equipment blows the resulting powders on through the boiler to the emission control device or "baghouse". This, in turn, maintains the temperature reduction efficiency of the boiler heat exchanger. Because of the various combustion stages or chambers incorporated in the incinerator, as well as the heat exchanger and gas recirculation feature, the Basic incinerator prevents burning particulate particles from entering the baghouse and burning holes in the Gortex filter bags. This, of course, insures optimum emission control efficiency. After the combustion gases exit the heat exchanger-boiler device, their temperature has been reduced to approximately 250 degrees Fahrenheit. Lime is injected at this point, which reacts with the HCL acid gas and neutralizes it in part; the reaction occurring as the gas flows toward the baghouse, with the reaction being completed on the surface of the Gortex bags of the baghouse, as the lime collects thereon. The County does not contest that the Basic Model 3500 incinerator, as proposed, will perform in a manner that will satisfy most of the criteria set forth in Rule 17-2.600(1)(d), F.A.C. It will achieve approximately 95% burnout in the combustion chambers. Mr. Cross, the County's expert witness, was concerned that DER had no criteria for a standard of "burnout" of the bottom ash. In fact, DER interprets the term "complete combustion" (in the above Rule), as requiring ash burnout of approximately 95%. The Basic incinerator will achieve 95% burnout. The high rate of burnout is achieved both by the multiple combustion chambers and the use of the moving pulse hearth which constantly shakes or stirs the burning material, ending with chains suspended at the end of the pulse hearth to impede bulky waste materials from exiting the combustion chamber before they are completely combusted. Odor is controlled, in accordance with Rule 17- 2.600(1)(a)2., F.A.C., by using air for combustion purposes which is drawn by blowers from the storage area of the untreated waste. The combustion blowers pull air from the waste storage area into the incineration system. The best means of odor control is by burning, which this incinerator will achieve. The County agrees that CO emissions from the incinerators will not exceed 100 parts per million by volume, dry basis, corrected to 7% 02, on an hourly average basis. Thus, CO will be within acceptable regulatory limits and is not at issue in this proceeding. Pursuant to stipulation, the only emissions at issue with regard to the proposed facility and permit are visible emissions, particulate matter and hydrochloric acid (HCL). Particulate matter consists of finely divided solids or liquid, and the hydrochloric acid is formed when chlorinated plastics are burned. Emissions are reduced in two ways. First, emissions from the stack of the incinerator will be diluted by ambient air which dilution increases as the stack height above ground increases. Airborne emissions are also reduced by directing combustion gases through pollution control equipment before they exit the stack. The pollution control equipment proposed for the incinerators at issue is an acid gas, dry lime scrubber baghouse, with dry lime injection. The incinerator facility cannot meet particulate and hydrochloric acid standards without the addition of a pollution control device, such as a dry lime scrubber baghouse. The baghouse is the best available technology for controlling particulates and hydrochloric acid, as well as controlling metals emissions. The baghouse works much like a vacuum cleaner with a vacuum cleaner bag to trap particulate matter. Baghouses have been in use since 1970, and the technology has been scientifically demonstrated and accepted. The proposed baghouse would consist of a multiple number of bags in excess of ten feet long. They are made of fiberglass, coated with Gortex, a permeable membrane material. They have an air to cloth ratio of 3 to 1. The Gortex bags are capable of trapping 99.5% of particles in the range of 1/10th of a micron in diameter. They are, thus, capable of trapping cigarette smoke, for instance, and are resistant to acids, certain alkalines, and temperatures up to 500 degrees Fahrenheit. The bags are wrapped around a wire cage and attached to a steel plate, anchoring them to the flues, which conduct the gases to them. All of the flue gases enter the baghouse and go through the bags and then exhaust to the atmosphere through the stack. The bags, thus, trap most particulate matter and metals. Additionally, lime will be injected into the flue gas stream for acid control before the flue gases reach the bags. The lime dust, a base, reacts with HCL, an acid, to produce calcium salts, which are PH neutral. The dry lime will be conducted from a silo or other means of storage in the form of fine dust or talc which enters a metering hopper so that the amount of lime injected into the system can be controlled. The lime is injected immediately after the gases are condensed and cooled to a 250 degree Fahrenheit level. This causes optimum reaction of the acid gases with the lime which then travel together to the bags. The Gortex bags are coated by the lime dust which further enhances the HCL removal reaction. Because of the recirculation of the superheated gases and the cooling of them through the heat exchanger device, it is very unlikely that any sparks or embers from the incinerator chambers will land on the bags to burn holes in them and, thus, reduce their efficiency. This is an inherent advantage of the design of the Basic incinerator when used with the Gortex' baghouse scrubber. There is a biohazardous waste incineration facility in operation at Stroud, Oklahoma. It uses a Basic incinerator also employing an acid gas, dry lime scrubber baghouse, in essence like the one proposed here. That incinerator has been tested for visible emissions, particulate matter emissions, and HCL emissions. The tests occurred while the incinerator was actually combusting twice the amount of medical waste proposed for the proposed incineratcrs. The visible emissions test at that facility resulted in an opacity of less than 5% (visible emissions). The PM test resulted in 0.014 grains per dry standard cubic foot. HCL emissions from the incinerator were tested at 43.6ppm (parts per million). The Stroud system thus achieved a 97.2% removal of HCL. A medical waste incineration facility is located at Fairfax, Virginia, which uses a baghouse and lime injection system. The Fairfax facility test results also establish that a baghouse lime injection system reduced particulate matter and HCL emissions to below the Florida standards. Experts testifying on behalf of both the applicant and the County agree that the design characteristics and pollution control capabilities of various lime injection systems and baghouses differ markedly. Certain baghouse designs would not be appropriate for the pollution control application at issue. The County's expert noted that the method of lime injection is a critical component of overall HCL control. Certain baghouses incorporate intermittent lime injection systems which are effective for protecting the individual baghouse components, but inappropriate for HCL removal purposes. The applicant's expert, Mr. Basic, also recognized the importance of the type of lime injection system involved. Various baghouse manufacturers inject lime at differing points within the system; and certain injection applications are, in his opinion, inappropriate for effective HCL control. Temperature is a critical factor in the effectiveness of the lime injection procedure in neutralizing the acid gases (HCL). The method proposed by the applicant of cooling the gases to approximately the range of 250 degrees Fahrenheit before injection of the lime has been shown to be effective in neutralizing the HCL gases at issue, when coupled with the Gortex-laminated, fiberglass bags upon which further neutralization will occur as the dry lime powder is deposited thereon and the gas passed through it. The baghouse cleaning system is also a component of major importance. Baghouse cleaning involves the removal of calcium chloride particulate buildup from the surface of the filter bags. They eventually become clogged with the precipitate, reducing the systems effectiveness unless they are periodically cleaned. Baghouses can be cleaned while the incineration system is shut down which is known as "off-line cleaning". They can also be cleaned during operation by "on-line cleaning". "Pulse-jet" cleaning involves taking a portion of the bags off line with a damper system bypassing the flue gases to other bags which remain in operation. The bags taken off line are then injected with a rapid pulse or pulses of compressed air, thereby removing the calcium chloride cake from the bags. The County's expert opined that pulse-jet cleaning is less effective than off-line cleaning and that it also requires a dedicated air compressor, as air from within the plant may contain moisture, oil or other contaminants, which are inappropriate for injection into the baghouse since they may permanently clog or otherwise harm the bag material. The applicant's expert, Mr. Basic, expressed like concerns regarding the baghouse cleaning system. He testified at length about the characteristics and appropriateness of on-line versus off-line cleaning. He established that off-line cleaning, also knowh as "reverse air" or "reverse jet" cleaning, is the most effective under the situation prevailing in this project and, in essence, agreed with the County's expert on this subject. Reverse air cleaning involves both the incinerator and the air pollution control system being shut down, with air from the blower being blown in reverse through the bags to remove the calcium carbonate residue. Mr. Basic's testimony establishes that a reverse air, off- line cleaning process can maintain the effectiveness of the Gortex- fiberglass filter bags and, thus, assure that emission and ambient air standards are continuously met by the facility. Stack Emissions Modeling of the stack emission results predicted at the facility with the originally-proposed 40-foot stack height was performed by Mr. David Buff, the applicant's expert witness in this regard. The model he employed demonstrated compliance with all ambient air quality standards set forth in Chapter 17-2, F.A.C. There is no ambient air quality standard in the rules at the present time for HCL, however. DER does have a policy, established without dispute in this record, that an acceptable ambient level of HCL would be 150 micrograms per cubic meter for a three-minute value and 7 micrograms per cubic meter on an annual average. Shortly prior to hearing, a "re-modeling" of the stack and resultant emissions was done, postulating a stack at 98 feet high. Five years of meteorological data from the Valdosta, Georgia, weather station were used to include such factors as prevailing winds, etc., which modeling ultimately demonstrated a three-minute maximum HCL concentration of 16.4 micrograms per cubic meter. This resulted in a maximum HCL concentration at ground level of a factor of 10 below the 150 micrograms per cubic meter level, which is acceptable under DER policy. The average annual impact of HCL concentrations would be 0.2 micrograms per cubic meter, well below the acceptable level of 7 micrograms per cubic meter annual average. Mr. Buff's model also predicted a maximum annual average impact at any location in the vicinity of the proposed incinerator of HCL at .16 micrograms per cubic meter. This maximum value is a factor of more than 40 below the administrative level of 7 micrograms per cubic meter on an annualized basis. A spatial distribution of the annual average hydrochloride concentrations in the vicinity of the incinerator demonstrates an annual average concentration declining to 0.09 micrograms per cubic meter in the direction of the City of Jasper. The 98-foot stack proposed by TSI thus meets all ambient air requirements. Although the stack height was changed from the 40 feet shown in the application to 98 feet, all other design elements of it, such as stack diameter, stack temperature, and gas flow rate, remain unchanged. The modeling of the 98-foot stack included all of the design criteria found in the application. There is, in essence, no dispute regarding the efficacy of the modeling performed by Mr. Buff. All modeling and modeling results were not controverted. In addition to the main stack, there is an emergency relief stack, also known as a "dump stack". The dump stack does not have pollution control equipment. It is opened when the system is first started up in order to purge the system. No waste is burned at that time. The stack is also opened after a shutdown during a cooldown period after all waste has been removed from the furnace. The likelihood that the relief stack will operate outside of a startup and cooldown period is very slight. The facility will have an electrical generator backup emergency power source in case of power failure. The primary reason for the stack's opening, power loss, is thus eliminated by the system as proposed. There is a relief valve in the steam line so that if steam pressure in the boiler exceeds operating pressure, the system can be relieved through the relief valve with the only loss being steam which would have to be replenished with soft water. Such a malfunction would not result in the emergency stack opening, however. The only other circumstance under which the emergency stack would open, and vent gases to the atmosphere without emission control, would be a malfunction of the blower or induced draft fan system which pulls the gases out of the main stack. This could be caused by failure of the drive belts or a burnout of a motor. With proper maintenance, the belts will not fail and the motors will function for years without replacement. In an emergency situation, however, if a shutdown does occur, the frequency of the pulse hearth can be increased to push the waste stream into the quench pit in approximately 20 minutes, thus, eliminating emission of pollutants through the stack. The County's expert, Mr. Cross, also agreed that most of the causes of the opening of the emergency dump stack have been eliminated by the proposed Basic design. In any event, even in an emergency situation where the dump stack must open, the inherent design capabilities of the incinerator, related to operating temperature, residence time and the multiple combustion chambers, result in only one part per million CO, as well as very low nitrogen oxide and hydrocarbon levels being emitted from the facility even with no other pollution emission control provisions. In the event the emergency stack opens, the highest HCL emissions occur immediately, but then quickly drop to acceptable levels. This is so because combustion of materials immediately in the furnace would be finished, but no other charging of the furnace would occur until the malfunction is alleviated. Rule 17-2.250, F.A.C., allows, in any case, with an emergency opening of dump stack, the excession of permit limits for up to two hours. The results of modeling the operation of the dump stack at a 40-foot height and at 30 pounds per hour of HCL emissions shows that the 7,500 threshold limit value ("TLV"), which the Occupational Safety and Health Administration ("OSHA") sets to protect worker safety, will not be exceeded anywhere off the plant property, which boundaries lie 50 meters or more from the stack location. The HCL administrative level set by DER (by policy) of 150 micrograms per cubic meter will be exceeded in an area out to approximately 400 meters from the stack. Beyond 400 meters, the level is less than that and drops off rapidly thereafter so that at 800 meters, under the model prediction, the level of HCL concentration would be only 57 micrograms per cubic meter and at 2,000 meters, 37 micrograms per cubic meter. The county prison site, the Hamilton County landfill, recreation park, middle school, county road camp, senior citizens center, other schools and a nursing home, of which concern was expressed about proximity to incinerator emissions, are all 900 meters or more from the site of the incinerator and the location of the stack. It has thus been established that ambient HCL concentrations will not reach the prohibited level of 150 micrograms per cubic meter for the three-minute average at any of these locations. The permit applied for is a "minor source construction permit". Such a permit allows the applicant to construct the source, having an initial startup and performance compliance testing period to demonstrate that the facility can meet emission standards provided for in the permit and related rules. After demonstrating compliance, the applicant can then seek an operating permit. The test methods required as conditions by DER's proposed grant of the permit and the "draft permit" are standard ones sanctioned by the U.S. EPA. They are reliable and acceptable and have undergone independent testing and development and are used by all states. Thus, the combustion chamber exit temperature must be monitored for the purpose of determining if the unit complies with the 1,800 degree Fahrenheit rule, the criteria for complete combustion. Oxygen must also be monitored for the purpose of determining if the incinerator is operating properly and achieving good combustion which is essential to control of hydrocarbons, nitrogen oxides, CO and other pollutants. When oxygen falls below certain levels, the computerized micro- processor monitoring system shuts down the loader to prevent charging of the furnace until combustion standards are again reached to prevent insufficient combustion due to low oxygen and excession of pollutant limits. In order to insure that the CO limit of 100 parts per million is not exceeded, a continuous CO monitoring capability will be installed within the incinerator. The lower the CO, the better the combustion efficiency. Although the rules require a 100 parts per million limit, CO test results at the Stroud facility, which is essentially identical to the one proposed, averaged 1.1 parts per million. Test results at the Stroud facility also demonstrated that the dry lime scrubbers installed there accomplish high HCL and particulate removal. The Stroud facility meets all Florida rule standards. Mr. Cross acknowledged that the test results on that facility demonstrate that dry lime scrubbers on medical waste incinerators "will do the job". Design details of the 98-foot stack and the lime injection baghouse scrubber facility were not included in their entirety in the application and the evidence adduced. Design details of the 98-foot stack, however, were provided in the application on page 6 as to the 40-foot stack. The changing of the stack height to 98 feet does not change the remaining design details, and they are still valid and have been proven so. Although no design or plans for the lime injection baghouse proposed have been adduced, the testimony of Mr. Basic establishes that such a facility will meet all pertinent emission standards prevailing in the Florida rules and policies, as such a facility did in the Stroud tests. Mr. Basic's testimony was unrefuted and establishes that the dry lime injection baghouse scrubber facility, such as he proposes and about which he is knowledgeable, based upon his manufacture, installation and operation of other incineration facilities, will reasonably assure that all pertinent disputed emission standards will be met (for particulate matter, opacity and HCL). Mr. Basic, as equipment vendor for the project, has responsibility for the entire incineration facility. He will oversee construction, installation and testing of the incinerators and emission control equipment (baghouse and stacks). He has guaranteed that all Florida emission standards will be met as the manufacturer and vendor for the project. A grant of the permit at issue should be conditioned upon Mr. Basic performing, as testified at the hearing and as agreed to by the applicant, as overseer for the construction, installation and testing of the proposed facility. Specific Condition No. 14 in DER's notice of intent to grant the permit requires the applicant to test the resultant ash to see if it is hazardous. Ash from the proposed facility must be tested in accordance with 40CFR 262.11, which requires testing and characterization of the waste. Ash from the proposed facility will be tested; and if it tests as hazardous, it will be handled as hazardous waste by sending it to an approved hazardous waste landfill or treatment facility. In any event, it has been stipulated by the applicant that the ash will not be deposited in a Hamilton County landfill; and the permit should be so conditioned. Most ash coming from infectious waste incineration is non-toxic. Controlled air incineration produces a sterile ash, which is a non-combustible residue, and may be disposed of in an ordinary landfill. Ash tested at the Stroud facility, after burning medical waste of the type to be incinerated in the instant facility, tested as non-hazardous. The ash will be removed from the facility in closed containers. Storage of Biohazardous and Biomedical Wastes DER regulates biohazardous waste incineration under the air permitting program, requiring an air permit, as sought in the instant case. DER does not require a separate solid waste treatment and sewage permit. Biomedical waste is regarded as a special waste which requires an element of care beyond solid waste, but does not require the extraordinary care required of hazardous waste. Sections 17-712.420 and 17-712.800, F.A.C., deal with the permitting of biohazardous waste storage. There are two ways in which an applicant can notify DER of its intent to use a general permit for the storage of biohazardous waste: It can apply for a general permit by notifying DER on a specific form of its intent to use a general permit for the storage of the waste; or It can include the information as part of an air permit application. With either option, there is no difference in the way DER processes the two types of notification. DER reviews the information submitted to make sure that it indicates that the facility will meet the requirements of Rule 17-712.420, F.A.C. The DER district waste program administrator, Mr. Mike Fitzsimmons, established in his testimony that the applicant has met the qualifications for the general permit for biohazardous waste storage. Five areas have been designated for storage of the biomedical waste to be incinerated at the TSI facility. It is anticipated that most of these areas will normally be empty. The storage areas are available, however, in case one of the incinerators is inoperative for any reason. There are contingency plans for re-routing the waste in the event one or both incinerators are inoperative for a significant period of time. Area A is the primary area of the facility where boxes are loaded onto a conveyor system and continuously fed into the furnaces. Area B is considered a secondary storage area where palletized boxes can be stored pending their placement onto the conveyor system for charging into the incinerators. The secondary area here can also be used for backup storage. Areas C and D are truck unloading docks,. The trucks, themselves, also can be used for storage capacity. Area E on Exhibit 7, the permit drawings, shows an outdoor storage area which will hold a number of trucks which transport the biohazardous waste. All of the trucks bringing waste into the facility will remain locked until brought to the unloading dock for unloading and incineration of their contents. The loading docks for the trucks located at the back of the facility are designed with drainage to prevent storm water runoff. Both the indoor and outdoor storage areas will be concrete. The concrete joints will be grouted and sealed, and the concrete will have an impermeable sealant placed on it. To maintain a sanitary condition, the area will be swept daily; and any spill area will be disinfected. The indoor areas will be disinfected weekly regardless of spills. Access to the proposed facility will be restricted to prevent entry of unauthorized persons. The outer perimeter will be enclosed with an 8-foot cyclone fence. It will be monitored with closed-circuit television. The building itself will only be accessible by authorized persons. The fence and all of the entrances will be marked with the international biohazardous symbol with the words "biohazardous wastes or infectious wastes". The facility will be operated so as to prevent vermin, insects or objectionable odors offsite. All materials will be packaged according to Rule 17-712.400(3), F.A.C. Refrigeration is not contemplated because EPA guidelines on management of infectious waste do not recommend refrigeration. Instead, storage times will be kept as short as possible prior to incineration. There will be minimal handling of boxes at the facility. Semi-trailers will be unloaded by means of an extendo conveyor system which will convey the boxes directly to the incinerators. If a box is dropped, breaks or a spill occurs, the area will be disinfected immediately. All floor drains, which will be installed both indoors and outdoors, will have a slight slope in the direction of the drain so that the floors can be scrubbed and hosed down and disinfected with all liquid material being flushed down those drains. Liquid waste created by the disinfection process can be safely disposed of thereafter in the city sanitary sewer system. The storm water management system on the site and the drainage sewage system are entirely separate, however. Employees will be required to wear either rubber or plastic gloves and white disposable clothing. All biohazardous waste generators (hospitals, etc.) and transport companies will be required to put the waste in "red bags", strong plastic bags. The medical waste will be required to be sealed in strong plastic bags, which are then placed by the generator of the waste in sealed cardboard boxes having a 275-pound bursting strength. All boxes must be marked with the name and address of the generator of the waste (hospital, etc.). The transporter of the waste, typically a trucking company, will be required to keep the trailers transporting the waste locked and the boxes intact and unopened. The applicant, as a condition of the permit, will not accept delivery of any waste shipments not so packaged and maintained. In fact, in addition to the rules governing the packaging and transport of biomedical waste contained at 17- 712.400, 17-712.410, F.A.C., TSI will require, by written contract, generators and transporters of the biomedical waste to insure delivery of waste properly packaged in accordance with Florida law regardless of which State the waste is generated and transported from. Additionally, the applicant will maintain records of waste origins and shipments in accordance with Rule 17-712.420(7), F.A.C., in its computerized record system. A detailed contingency plan will be prepared for the proposed facility by Lloyd H. Stebbins, P.E., an expert in environmental incident planning. The contingency plan will include more detail than is required by the biohazardous waste rules. The plan will address how medical waste is handled in order to insure public safety and the safety of employees as it is transported to and enters the plant and how ash will be safely handled when it exits the plant. Mr. Stebbins will also prepare an operation plan which will include personnel training in disinfection procedures and a description of those procedures for submittal to DER as a condition of a grant of this permit. That operation plan will contain procedures for all three types of disinfection methods authorized by Rule 17-712, F.A.C. This will enable the applicant to have the flexibility to use all three procedures, hot water, sodium hypochlorite, iodine or an EPA approved germicide. Mr. Stebbins will direct and provide training to insure that personnel comply with the regulations concerning disinfection and proper application of disinfectants. As an additional safety factor, the facility is designed to operate efficiently at approximately 85% of its actual capacity in order to allow for "down time" and maintenance. Standing TSI has challenged the County's standing to participate in this proceeding, asserting that Hamilton County, through its duly-elected Board of County Commissioners, does not possess a substantial interest in the outcome of this proceeding different from that of the public generally. It contends that the concerns various members of the general public might have concerning location and installation of the incinerator facility are the only concerns that the County has in participating in this proceeding; and, therefore, that the County has no substantial interest of its own justifying its standing to be a party to this proceeding. The record, however, reveals a strong citizen opposition in the County and City of Jasper to the applicant's proposed project. During the public comment portion of these proceedings, it became obvious that the citizens of Hamilton County have a variety of health and safety concerns which have engendered wide spread opposition to the applicant's project. Principal concerns are the matters of transportation and potential spillage of infectious hospital- generated medical wastes which the incinerator will be treating. Additionally, a strong concern has been expressed by various citizens of Hamilton County and the City of Jasper, concerning potential HCL emissions and their potential negative health effects on residents of the city and county, particularly those who utilize the many publicly-owned facilities located in proximity to the project site. These facilities include a middle school, a senior citizen center, a county road camp or prison, the county landfill, county equipment, a bridge and other buildings, as well as the fact that the material to be incinerated will be transported on trucks through a residential area. Additionally, the Hamilton County Correctional Institution is immediately adjacent to the proposed project site and employs several dozen county residents. Concerns were also expressed about increased traffic flow resulting from trucks bringing waste through the county and city to the proposed incinerator site, as well as the health and safety of the citizens who will be employed at the proposed facility itself, and the lack of sufficient emergency equipment and facilities within Hamilton County. Many citizens expressed their opposition to the proposed facility at the public comment portion of the hearings, through petitions submitted to their city council and the board of county commissioners and at public meetings conducted by those two governmental bodies. Thus, it can be inferred that there is a concensus of opposition by citizens of the city and the county which has been expressed to their respective governing commissions, who are the Petitioner and Intervenor in this proceeding. There is no question that the proposed project has the potential to cause some pollution or degradation of air and water in Hamilton County and the City of Jasper. Section 125.01(1), Florida Statutes, delegates broad powers and duties to county governments. Those powers and duties are enumerated in the Conclusions of Law below and include such authority as to establish and administer programs of air pollution control; to provide for and regulate waste and sewage disposal; to operate solid waste disposal facilities pursuant to Section 403.706(1), Florida Statutes; to establish, coordinate and enforce zoning and such business regulations as are necessary for public protection; to perform other acts not inconsistent with the law which are in the common interest of the people of the county, and to exercise all powers and privileges not specifically prohibited by law.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and aguments of the parties, it is therefore, RECOMMENDED that DER enter a final order approving TSI's applications for permits for the subject two biological waste incineration facilities in accordance with the conditions specified in the notice of intent to grant the permit and enumerated in this Recommended Order.

Findings Of Fact This cause comes on for consideration based upon the petition of John C. Walker and others, residents of Fort Myers, Florida, who have challenged the Respondent, State of Florida, Department of Environmental Regulation's intention to grant a Complex Air Source Permit to the Respondent, Lee County Board of County Commissioners, for purposes of constructing a four-lane road at Daniels Road, Lee County, Florida. The Respondent, State of Florida, Department of Environmental Regulation, is an agency charged with the promotion and protection of air quality within the State of Florida. The authority for this function is found in Chapter 403, Florida Statutes, and various rules enacted to implement the provisions of this statute. Specifically, as it pertains to this dispute, the Respondent, State of Florida, Department of Environmental Regulation, is charged with the maintenance of Ambient Air Quality Standards. The standards are set forth in Chapter 17-2, Florida Administrative Code. To carry out this function, Rule 17-2.06, Florida Administrative Code, has been enacted, which establishes maximum limiting levels for Ambient Air Quality Standards. This sets the allowable limits for pollutants existing in the ambient air, the purpose for such standards being the protection of human health and public welfare. It involves the consideration of the pollutants, sulphur dioxide, particulate matter, carbon monoxide, photochemical oxidants (by measurement and correction for interference due to nitrogen oxide and sulphur dioxide), hydrocarbons (used as a guide in devising implementation plans to achieve oxidant standards, to be measured and corrected to methane), and nitrogen dioxide. The Respondent, Lee County Board of County Commissioners, is a unit of local government in the State of Florida charged with the function of carrying on the business of government for that county, to include the construction of those roads necessary to accommodate the needs of the public. To that end, on February 1, 1978, the Respondent, Lee County Board of County Commissioners, applied for a Complex Air Source Permit to be granted for the construction of a four-lane road at Daniels Road, Lee County, Florida. Subsequent to that initial application, revisions of the data provided in support of the application were made on October 12, 1978, and again on January 19, 1979. That application, as revised, may be found as the Respondent's (Lee County) Exhibit No. 1 admitted into evidence and includes aerial photographs. On May 4, 1978, through the person of Phillip R. Edwards, District Manager of the State of Florida, Department of Environmental Regulation, South Florida District, an indication was given that the department intended to issue a Complex Air Source Permit to the Lee County Board of County Commissioners. This exhibit is found as the Respondent's (Lee County) Exhibit No. 2 admitted into evidence. An engineer for the South Florida District, State of Florida, Department of Environmental Regulation, has made a review of the revisions in addition to the original application and is still of the persuasion that the Complex Air Source Permit should be granted. This letter of intent to grant the permit makes reference to the permitting chapter of the Florida Administrative Code pertaining to Complex Air Source Permits and other types of permits. Rule 17-4.07, Florida Administrative Code, sets out the general criterion which must be met prior to the issuance of the Complex Air Source Permit. That provision establishes the need for the applicant to affirmatively provide reasonable assurances based on its plans, test results and other information that the construction of the road and operation on that road will not discharge, emit or cause a violation of the Ambient Air Quality Standards set forth in Rule 17-2.06, Florida Administrative Code, previously referenced. In this case, those assurances have been given. In examining the particular pollutants set out in the Ambient Air Quality Standards table, sulphur dioxide and particulate matter are not items of significant concern, because motor vehicles do not promote the emission of those pollutants in quantities sufficient to exceed the maximum limiting levels. In measuring the amount of carbon monoxide, Lee County utilized a technique known as the representative site method, to be applied in the Cal-Air Model. The ecolyzer which measures this pollutant, was placed in various locations near the intersection of U.S. 41 and Daniels Road, with the object in mind to achieve the gravest readings as a basis for projecting the future amounts of carbon monoxide that would be present in the area of the proposed road expansion. The traffic projections and average speed at the intersection were factored in by Joseph Ebner, P.E., an expert in traffic engineering. The most recent statement of those traffic projections may be found in the January 19, 1979, revision to the application offered by the Respondent, Lee County Board of County Commissioners, which is a part of that Respondent's Exhibit No. 1. In that revision, as was the case of the revision of October 12, 1978, and the original application, the average speed at the intersection was established at fifteen miles per hour, calculated from an engineering textbook, "Highway Capacity Handbook (1975), Highway Research Board, Special Report No. 87". This represents the lowest average speed for an eight-hour period in a signalized intersection of an urban area. In arriving at the traffic count calculations, Mr. Ebner relied on the Lee County Transportation Study, Technical Report No. 6, which contains traffic projections for the year 1990. A copy of this report may be found as Petitioner's Exhibit No. 10 admitted into evidence. The statistics found in that report take into account the projected construction of a regional airport located east of Interstate-75 on Daniels Road, to be opened in the year 1982, and the Opinion that Canal Road, which will intersect with Daniels Road, will be opened in that same year. Calculations made in the January 1, 1979, revision are based upon the belief of a rate of increase in traffic to be eight percent per annum in the area of the intersection of U.S. 41, Cypress Lake Drive and Daniels Road. (At this point it should be indicated that the calculations in the revision of January 1, 1979, labeled, 8-hour Co. Concentrations, U.S. 41 & Cypress Lake Drive [natural traffic mix], are improperly depicted in the columns entitled, "U.S. 41 and Cypress Lake Drive" and must be transposed in their labeling to arrive at the proper mathematical result.) When that adjustment is made, it is established that the highest concentration of carbon monoxide in an eight-hour period in the intersection of U.S. 41 and Cypress Lake Drive in the location of the northwest quadrant for the years 1980 through 1990 was in the year 1980. In that year the measurement would be 9.13 mg/m3 in an eight-hour period. The second most severe year is 1981, in which the measurement is 9.10 mg/m3 as the highest eight-hour carbon monoxide concentration levels in that intersection. The balance of those measurements for the years 1982 through 1990 may be found in the Respondent's, Lee County Board of County Commissioners, Exhibit No. 1 in the January 19, 1979, revision to the permit application. Finally, it should be indicated that the projections made by the Lee County Board of County Commissioners in its application are premised upon a vehicular mix of ninety-four percent automobiles and six percent trucks. Tom Davis, an engineer for the Department of Environmental Regulation, who has the responsibility to review permit applications for Complex Air Source Permits, was involved in advising the applicant on the requirements for compliance for the granting of the permit. Through his involvement, Mr. Davis has been satisfied with the techniques used by the applicant in its efforts at measuring the carbon monoxide and the modeling necessary to answer the ultimate question of whether or not this project will violate the Ambient Air Quality Standards. In this instance, Mr. Davis does not believe those air quality standards will be violated. His testimony established that there are no models designed specifically for the measurement of photochemical oxidants, hydrocarbons or nitrogen dioxide. The hydrocarbons and nitrogen dioxide are area wide phenomena and are not subject to such specific site measurement. However, the area wide monitoring which has been done for nitrogen dioxide throughout the State of Florida, and more particularly in Lee County, Florida, has never shown that pollutant to exceed ten percent of the maximum limiting level. Moreover, carbon monoxide, hydrocarbons and nitrogen dioxide are felt to decrease at roughly the same percentage rate throughout the years, so that the decrease in the carbon monoxide levels at the project site beyond 1980 would reflect a similar decrease at that site in the amounts of hydrocarbons and nitrogen dioxide. Therefore, if there are no problems with carbon monoxide there is no reason to believe that there would be a problem with hydrocarbons and nitrogen dioxide, nor with the photochemical oxidants which are a bi-product of hydrocarbons and nitrogen dioxide combinations. These opinions stated herein are those of Mr. Davis, and David Barker, Ph.D., an air quality expert who testified in behalf of the Respondent, Lee County Board of County Commissioners, agrees. As indicated, these opinions are well founded. Notwithstanding the belief that the Respondent, Lee County Board of County Commissioners, has complied with the requirements of law, an examination of the Petitioners position would seem to be indicated. The Petitioners' argument against the approval of the Complex Air Source Permit falls into two broad categories. The first of those categories has to do with the allegation that the Respondent, Lee County Board of County Commissioners, failed to comply with the instructions in the application form. After considering the testimony in this cause and the exhibits submitted, this contention on the part of the Petitioners is rejected. The second basis for attacking the application concerns the techniques for gathering and applying the data which was utilized by the Respondent, Lee County Board of County Commissioners, in their efforts to establish reasonable assurances that the project would not violate Ambient Air Quality Standards in terms of the maximum limiting levels set forth in Rule 17-2.06, Florida Administrative Code. To this end, the Petitioners offered a series of competing statistics through their exhibits, in terms of traffic projections. In addition, their expert on air quality, Dr. Detar, was of a different persuasion on the question of the average automobile speed through the signalized intersection U.S. 41 and Daniels Road. In Dr. Detar's mind the average speed would be eight miles per hour as the low average speed for an eight-hour period. In view of all the testimony, this projection of the low average speed is not found to be acceptable. Finally, the Petitioners were of the persuasion that the average mix of automobiles and trucks in the area of the project would be more along the lines of the national average of eighty percent cars and twenty percent trucks. The studies conducted by the Respondent, Lee County Board of County Commissioners, in prior projects demonstrated the efficacy of the ninety- four percent automobiles and six percent trucks standard. In measuring other sources of pollution than sulphur dioxide and particulate matter (which the Petitioners do not question in this case), Dr. Detar believed that hydrocarbons and nitrogen dioxide could be modeled. His explanation of the modeling technique, when contrasted with the argument of the Lee County Board of County Commissioners and the State of Florida, Department of Environmental Regulation, to the effect that those two substances may not be modeled on a specific site basis, failed to be persuasive. In summary, in contrasting the evidence offered in behalf of the Petitioners with that offered in behalf of the Respondent; the Respondent, Lee County Board of County Commissioners, has demonstrated reasonable assurances that maximum limiting levels of the applicable pollutants will not be exceeded in the area of the project. The various memoranda and proposed findings of fact and conclusions of law have been reviewed by the undersigned, and to the extent that those items are not inconsistent with the findings of fact rendered herein and conclusions of law and recommendation, they are hereby acknowledged by the entry of this Order. To the extent that those aforementioned items are inconsistent with the findings of fact, conclusions of law and recommendation by the undersigned, they are rejected.
Recommendation It is recommended that the Respondent, Lee County Board of County Commissioners, be granted a Complex Air Source Permit for the construction of the improvements at Daniels Road, Lee County, Florida.
