The Issue At issue in this proceeding is whether a citation and imposition of a $1,500.00 fine for installing a septic tank without a permit was properly imposed on Respondent, Paul Ware, a/k/a Paul Montgomery-Ware, by Petitioner, the Department of Health, Polk County Health Department (the "Department").
Findings Of Fact Respondent is the owner of three contiguous lots in Polk County (Bevington Manor, PB 20 PG 47, Lots 100 through 102), purchased via tax deed recorded on October 21, 2003. Respondent's lots are surrounded by property owned by Irma Walker, whose son, William Walker, testified at the hearing. Respondent apparently intended to develop his lots as a commercial enterprise and had erected a Quonset-type structure on the property. From his mother's adjoining property, Mr. Walker regularly observed Respondent's activities. Mr. Walker testified that Respondent was using his property to operate a motorcycle repair shop. On June 4, 2004, Mr. Walker observed Respondent using a backhoe on his property. Mr. Walker testified that Respondent was installing a septic tank. Mr. Walker told his mother, who then initiated inquiries as to whether Respondent had a permit to install a septic tank. When her inquiries met with a negative response, Ms. Walker called in a complaint to the Department. On June 7, 2004, the Department sent environmental specialist Susan Patlyek to the site. Ms. Patlyek observed infiltrator chambers on the site. Infiltrator chambers are used only in connection with OSTD systems. Ms. Patlyek also observed a recently excavated area and a rented backhoe, commonly used to dig out areas for septic tank installation. It was obvious to Ms. Patlyek that a septic tank and drainfield had been installed on Respondent's property, though no permit had been issued by the Department allowing installation of an OSTD system. Installation of an OSTD system without a permit constitutes a sanitary nuisance. The Department sent a letter to Respondent dated June 8, 2004, advising him of the need to abate the nuisance by obtaining a permit. With the letter, the Department enclosed a blank application form that Respondent could have completed and returned to the Department's permitting office. Respondent replied by contending that the Department lacked jurisdiction over activities on his land and suggested that the Department initiate court action. Respondent also returned the application form in its original blank form. The Department then issued Respondent a citation for violations of Subsection 381.0065(4), Florida Statutes (2003), and Florida Administrative Code Rule 64E-6.003(1), constructing an OSTD system without a permit; and for a violation of Subsection 386.041(1)(b), Florida Statutes (2003), maintaining a sanitary nuisance. The citation provides for a $1,500.00 fine. The Department's citation also informed Respondent of his right to a hearing pursuant to Chapter 120, Florida Statutes (2003). Respondent contends that the relegation of this matter to an administrative forum is unconstitutional.
Recommendation RECOMMENDED that Petitioner, the Department of Health, Polk County Health Department, enter a final order imposing a $500.00 fine for the violations described in the above Findings of Fact and Conclusions of Law. DONE AND ENTERED this 30th day of November, 2004, in Tallahassee, Leon County, Florida. S LAWRENCE P.

Findings Of Fact At final hearing, the parties stipulated to the following facts: The Department of Environmental Regulation is an administrative agency of the State of Florida created by Chapter 75-22, Laws of Florida, and vested with the power and duty to implement and enforce the provisions of the Florida Air and Water Pollution Control Act, Part I, Chapter 403, Florida Statutes. Pursuant to these Acts, the Department is authorized to regulate the construction and operation of solid waste disposal facilities and stationary installations reasonably expected to be sources of pollution. Respondent, City [of North Miami], owns the property on which is located a solid waste facility known as "Munisport Sanitary Landfill" located at 14301 Biscayne Boulevard, North Miami, Dade County, Florida; latitude 25 degrees 54' 9" North, longitude 80 degrees 9' 5" West in Sections 21 and 22, Township 52 South, Range 42 East. Respondent, Munisport, operates a solid waste disposal facility under contract with the City. On March 7, 1977, the Department issued to the City of North Miami permit/certification number 13-31-028GM (hereinafter "dredge and fill permit") which modified and superseded permit/classification number 13-31-0286. The permit was issued under the provisions of Sections 253.123, 253.124, and 403.087, Florida Statutes, and Chapter 17-4, Florida Administrative Code. The permit also provided water quality certification required by Public Law 92-500. The dredge and fill permit was issued for the purpose of constructing a continuous 5,000 foot-long earthen dike with a modified top width of 12 feet aligned waterward of the mean high water line such that the waterward toe of the dike would be on or landward of the property line. Approximately 6,000 cubic yards of material would be dredged from the 63-acre tract located behind the dike and waterward of the mean high water line. Portions of the tract would be excavated to minus 35 feet mean low water to form nontidal lakes. Approximately 1,000,000 cubic yards of fill material would be enplaced as follows: Clean fill to be utilized to produce an elevation of a minimum of two feet above the calculated ground water table, after which fresh refuse and a two-foot final cover of clean fill would be placed. Within a zone of 100 feet from the landward crest of the dike, yard trash and construction debris would be the only types of solid waste acceptable as fill, and A ten-foot wide by three-foot deep circulation canal would be dredged on the outside perimeter of the dike. General condition 13 of the dredge and fill permit provides that the permit does not indicate an endorsement or approval of any other Department permit/approval that may be required for other aspects of the total project. A solid waste operation permit would also be required. On June 8, 1979, the City and Munisport received from the Department Operation Permit No. SWO-13-5152 (hereinafter "solid waste operation permit"). The purpose of the solid waste operation permit was to allow and regulate the placement of solid waste (refuse, yard trash and construction debris) in the area behind the dike described above and on adjacent uplands in order to generate an appropriate elevation for a golf course. General condition number two of the solid waste operation permit states that: This permit is valid only for the specific processes and operations indicated in the attached drawings or exhibits. Any authorized deviation from the approved drawings, exhibits, specifications, or conditions of this permit shall constitute grounds for revocation and enforcement action by the Department (emphasis added). Specific condition number six of the solid waste operations permit provides that the subject facility be operated at all times at the maximum level of efficiency so as to minimize the adverse effect on the environment of contaminated storm water runoff or leachates which cause degradation of surface or ground waters. Specific condition number nine of the solid waste operation permit provides that "no solid waste shall be placed within thirty feet of any existing or future lake". Prior to the issuance of the solid waste operation permit, Respondents' permit application was subjected to a de novo review during a Section 120.57(1), Florida Statutes, hearing requested by the Florida Audubon Society and others. The record of these proceedings explained and expanded upon the application and, therefore, became a part thereof. Respondents' consultant testified in these proceedings as follows: We have an agreement with the Department of Environmental Regulation that goes back several years that we would not dig up any old land fill material nor would we place any land fill material in an area that would eventually become a lake. Testimony of Mr. Thomas Joseph Checca on October 18, 1978; Transcript of proceedings in Florida Audubon Society, et al. v. State of Florida, Department of Environmental Regulation, City of North Miami, Florida and Munisport, Inc., DOAH Case No. 78-316. On October 25, 1979, an inspection of the above-described facility was made by Mr. Scott Quaas, an employee of the Department, who observed that two lakes had been constructed in old waste on the site without the required 30-foot setback as required by the aforementioned permit conditions. A letter of notice was issued by the Department regarding that and other violations on November 16, 1979. On December 18, 1979, a follow-up inspection of the subject facility was made by Mr. Quaas, at which time it was observed that two more lakes had been excavated through waste previously deposited at the site, thereby causing such waste to come in direct contact with the water in the lakes adjacent thereto. It was also observed that no 30-foot setback was provided at the new lakes. Notice of these additional violations was provided to Munisport on January 16, 1980. An on-site meeting regarding the above-described violation was held on January 24, 1980, at which time it was agreed that Respondents would reply by February 1, 1980, as to whether corrective actions would be taken regarding the aforementioned violations. As of the date of final hearing in this cause, corrective action had been taken to eliminate these violations. Specific condition number 13 of the solid waste operation permit requires the posting of a performance bond or other security acceptable to the Department which adequately covers the cost of monitoring and final closing procedures required under the permit and Chapter 17-7, Florida Administrative Code, and procedures listed in the application for permit which may become necessary to correct any pollution detected at the site in violation of Department rules. No such bond or security has been posted with the Department. Extensive discussions between the Department and representatives of the City and Munisport have failed to produce agreement regarding the terms of a performance bond or security. The parties were notified of this violation and were given an opportunity to respond. Leachate (runoff containing pollutants) has been allowed to enter lakes on the site. A leachate plume containing ammonia has been detected beneath the subject sanitary landfill site, which plume has reached ground waters of the State and is being observed to be moving off the site in an east- southeast direction, toward Biscayne Bay. This leachate plume contains total Ammonia-Nitrogen (NH3-N) in amounts which are substantially in excess of the water quality standards of .5 milligrams per litre for Dade county, Florida. See, Chapters 24-11(4), Dade County Code. It was not anticipated when Operation Permit Number SWO-13-5152 was issued that leachate would be allowed to enter the lakes or that a leachate plume would form in the manner which is presently being observed. In addition to being a pollutant, Ammonia-Nitrogen is the first substance generally observed when a leachate plume forms. There exists a significant possibility that other pollutants contained in solid waste deposited at the site will also begin to reach ground waters of the State and the waters of Biscayne Bay. General condition number eight of the solid waste operation permit states that: This permit does not relieve the permittee from liability for harm or injury to human health or welfare, animal, plant, or aquatic life or property and penalties therefore caused by the construction or operation of this permitted source, nor does it allow the permittee to cause pollution in contravention of Florida Statutes and department rules, except where specifically authorized by an order from the department granting a variance or exception from department rules or state statutes. Specific condition number 15 of the solid waste operation permit states that: These permit conditions do not exempt the applicant from complying with pollution control requirements of other Federal, State, Municipal, County or Regional water pollution control rules, regulations, ordinances or codes, nor does it authorize any violation thereof.
Recommendation Based upon the foregoing findings of fact and conclusions of law, it is RECOMMENDED that a Final Order be entered revoking the permits and certification which are the subject of this proceeding in their entirety or such lesser action as may be deemed appropriate by the Department in the exercise of its discretion as the State agency charged with the power and duty to control and prohibit the pollution of air and water under Section 403.061, Florida Statutes, and as the agency responsible for the implementation and enforcement of the provisions of the Florida Resource Recovery and Management Act which regulates the appropriate disposal of solid waste and landfill operation in this State.

Findings Of Fact THE PARTIES CMI is a Florida corporation authorized to do business in Florida. CMI owns a mine site as is depicted in the permit application, which mine site is known as "Pine Level". Alan R. Behrens owns residential property approximately two miles from Pine Level, which abuts Horse Creek. He maintains an individual well for domestic and other purposes, and is a substantially affected person under the statute. Charlotte County is a government entity and a political subdivision of the State of Florida, and is a substantially affected person under the statute. The City of North Port is an incorporated municipality of the State of Florida, and is a substantially affected person under the statute. The Environmental Confederation (ECOSWF), a citizens group, is a substantially affected person under the statute. The District is the agency with the responsibility for reviewing and ruling upon CMI's water use permit application. APPLICATION AND PROCESS CMI proposes to operate a phosphate mine facility at "Pine Level" ("site"). The site is located approximately seven miles west of Arcadia, DeSoto County, Florida. The mine reserves at the site are approximately 17,700 acres. 9,000 to 10,000 acres are projected for mining. In 1978, Consumptive Use Permit No. 200103, was issued and in 1986, the current owners purchased the corporation which held the permit, and changed the name of the corporation to CMI. The Industrial Water Use Permit has not been used since it was issued to a prior owner of the site, and provided for average daily withdrawals of 13.6 mgd from wells. In 1984, this permit was renewed and modified to provide for average daily withdrawals of 12.8 mgd from deep wells. The groundwater withdrawals currently sought by CMI is 6.9 million gallons per day ("mgd") average daily withdrawal, which totals include 5.1 mgd from deep wells for use in the amine flotation process and 1.7 mgd for sealing the matrix slurry pumps. This reduction to 6.9 mgd in permitted withdrawals is a significant reduction. In addition, the proposed permit allows 3.7 mgd to be withdrawn from the surficial aquifer by dewatering mine cuts. In November, 1990, CMI submitted an application for renewal. In November 1991, CMI submitted to the District a revised Water Use Application No. 200103.02 ("application") to renew and modify the existing water use permit. The District requested more information, and CMI provided additional information and supplemental responses to aid in the review and evaluation of the application. The District prepared and submitted a Notice of Intent to Issue Permit and the District staff has prepared a "draft" Permit No. 200103.02 authorizing the withdrawal of the quantities requested in the application with certain conditions. In addition to renewal and modification of the water use permit, which is the subject of this proceeding, CMI will be required to participate in numerous regulatory reviews and permitting procedures (i.e. a development of regional impact evaluation, a federal environmental impact statement, federal approvals under the Clean Water Act [including a national pollutant discharge elimination system ("NPDES") permit], and a conceptual reclamation plan review) before CMI may commence mining, and consequently, begin any withdrawal of water. The mining process will utilize large walking draglines to excavate over burden and stack it beside the active mining area for land reclamation. The ore material called "matrix" will be dug up by the draglines, placed into an earthen pit where it will be slurried with a high pressure water jet. A pump will pick up this slurried matrix material, pump it back to the processing plant where it will first go through various separation devices, including screens and cyclones. The course material termed "pebble" will be separated and parts of that will be directly saleable as a product. The bulk of the phosphate product is contained in intermediate-sized material called concentrate feed. The concentrate feed consists of ore and sand. The ore is separated from the sand in a process called "flotation". The flotation process is a two stage process that ends up separating the tailings sand, which can then go back to the sand-clay flocculation and mixing units, and be pumped out ultimately for land reclamation back in the mine-out areas. The phosphate product which is called "wet rock", is placed in storage bins where it can drain, and be loaded onto rail cars for shipment. The "amine flotation process" is the second stage of flotation where sand and phosphates are separated. This process requires clean water for the amine flotation phase, because any amount of contaminants, including organic reagents, will adversely affect the process. Any mineral particles must be removed so that the amine may attach itself to the phosphate. Any contaminants will destroy or significantly and adversely affect not only the phosphate recovery, but the entire flotation process. Deep well water is requested for use in the amine flotation process because it is clean. All phosphate mines in Florida currently rely on deep well water. 5.2 mgd is the minimum amount of "clean" water needed to assure efficient processing of the amine flotation process of the mine beneficiation plant. Deep well withdrawals are also commonly used for the purpose of sealing or protecting the packing of pumps at various points in the mine system in order to avoid damage to the equipment. These wells are often referred to as "sealing water wells". The Pine Level mine will require 1.7 mgd for this purpose. Water for the sealing water wells must be clean and clear in order to effectively seal pumps for leaks. The Pine Level project will provide 400-500 construction jobs during the construction period. It will provide approximately 200 full-time jobs with an annual payroll of about five million dollars once it is in operation. It will result in about one thousand additional jobs providing services to the development. It will pay in excess of one million dollars a year to DeSoto County in ad valorem taxes. TECHNICAL CRITERIA The water use is a reasonable and beneficial use. 5.2 mgd groundwater withdrawal is "necessary to fill a certain reasonable demand." The technical criteria relating to water level or rates of flow impacts set forth in Rule 40D-2.301(1)(d), Florida Administrative Code, are not applicable in this proceeding because the District has not established any regulatory levels or rates of flow for the area encompassed by the application. In addition, this presumption only addresses surface water withdrawals. Phosphate mining is a beneficial activity and is consistent with the public interest. There is no significant risk of salt water intrusion. The water use withdrawal will not degrade the water quality in the aquifer by causing any contamination plume to spread. There have been no contaminant plumes identified on site. GROUNDWATER IMPACTS There is sufficient ground water at the site of a suitable quality and quantity to support the proposed phosphate mining and beneficiation activities. The local hydrogeology at the site consists of an upper layer known as the surficial aquifer. Rain penetrates the surficial aquifer to flow vertically to the water table. The water that is not consumed by vegetation at this layer will flow either to a nearby stream channel or will leak down through a semi- confining layer. The water continues to seep vertically into the lower underlying limestone aquifers. There are three limestone water-bearing layers: the intermediate, the Suwannee or Upper Floridan, and the Avon Park or Lower Floridan aquifers, respectively. The intermediate and the underlying Suwannee aquifer are separated by another semi-confining layer. Likewise, the Avon Park aquifer and the Suwannee aquifer are separated by another semi-confining layer. At the site, wells in the intermediate aquifer will draw water to seal the bearings on the matrix slurry pumps. There will be one deep well in the Suwannee and one deep well in the Avon Park to draw for the beneficiation plant. The groundwater modeling performed by CMI simulated the four aquifers, that is, the surficial aquifer and each of the three limestone aquifers. An Aquifer Performance Test ("APT") was performed at the site. The data generated from the APT was used to calculate various aquifer parameters, for example, transmissivity, storage coefficient, and leakiness. This information was then used in setting up the groundwater flow model that ultimately was incorporated into the application. During the District staff's review of the application, the deep well withdrawal quantities requested by CMI were compared with approximately 6 other phosphate mines of comparable size, acreage, and type of operation. As a result of this comparison, the staff found CMI's requested use to be less than the other six phosphate mines. The use of recycled water in the amine flotation process in place of deep well water in the past by CMI has proven unsuccessful because a constant temperature and a constant ph level could not be maintained with recycled water, and recycled water contains traces of fatty acids and oils, which also negatively affect the amine flotation process. C.F. Industries, Inc., has been operating a phosphate mine in Hardee County, Florida, since 1978. C.F. Industries, Inc., has since 1983 at the Hardee County mine, successfully substituted recirculation water for deep well water for operation of the amine flotation circuit on a routine basis. C.F. Industries, Inc., presently plans to employ substitution of some recirculation water for deep well water in a new yet-to-be permitted mine. C.F. Industries, Inc., at its existing Hardee County mine requires use of deep well water for start-up purposes to "charge" the system. C.F. Industries, Inc., at its existing mine, uses deep well water to respond to abnormal operational conditions, including excessive rainfall events, when the quality of the normal recirculation water is not suitable for substitution of deep well water. Neither CMI, nor District staff was aware prior to hearing, that the C.F. mine was successfully substituting recycled water for deep well water in the amine flotation process. At the time of making the representations to the District about necessary water quality requirements of the flotation process, CMI had a study, entitled, Amine Water Evaluation, Pine Level Project, July 27, 1984, ("Pilot Plant Study"), which concluded that deep well pumping and discharge could be reduced by use of water drawn from mine cuts. The Pilot Plant study was site specific to CMI's proposed phosphate mine. The Pilot Plant study bench tests were verified in the same pilot plant facility CMI uses to verify the grade of ore on the Pine Level Site. The Pilot Plant study or its results were known to CMI officials or experts involved in the permit application at issue in this case. CMI did not inform District staff of the existence or conclusions of the Pilot Plant study. The Pilot Plant study indicates that CMI could reduce its water usage by substituting water from mine cuts for deep well water. CMI did no studies to determine if the substitution of mine cut water for deep well water, as suggested by the Pilot Plant Study, was feasible to implement. SURFACE WATER IMPACTS The phosphate ore (matrix), is extracted by an excavation machine called a "dragline", which opens mining cuts of approximately 32 to 35 feet in depth, 330 feet wide, and up to 4,000 feet long. Seepage occurs into the mine cuts from the water table, and must be pumped out in order to see and extract the matrix. This dewatering is also necessary to protect the draglines against slope stability problems. Water pumped out of the mining cuts is introduced into the mine water recirculation system which is operated for purposes of collecting and recycling water within the mine complex. The matrix that is extracted from the mining cut is placed in a shallow excavation near the cut, and is converted to a slurry and, thereafter, transported hydraulically to the mine processing (or "beneficiation") plant. The beneficiation plant uses considerable quantities of water, utilizing supplies from within the mine system (i.e. surface water) and water from deep wells. Sand tailings and sand and clay mixture are by-products of the mining process. Recycled water is used to transport waste clay and sand from the plant to the disposal and reclamation areas. Reclamation takes 1-2 years for areas reclaimed with sand tailings and 5-6 years for areas reclaimed with a sand-clay mixture. Groundwater that is used in the processing plant is recycled. Water within the mine is recycled a number of times, and CMI's proposal calls for 90 percent of the total mine demand to be satisfied by this recirculation system and approximately 96 percent of the water used is recyclable water. DEWATERING AND WATER BALANCE CMI's mine pit dewatering activities result in the withdrawal of water from the surficial aquifer. A "water balance" demonstrates that requested quantities relate to reasonable mining, processing, and dewatering needs. The "water balance" for the mining operation evidences a balance between sources and uses/losses. The sources of water in the CMI water balance that input to the mining operation include groundwater from wells (6.9 mgd), mine cut dewatering or water table drainage (3.7 mgd), and collected rainfall (3.1 mgd). Uses and losses associated with the mining operation include water retained in clays (6.7 mgd), water shipped with final product (.7 mgd), evapotranspiration and evaporation (3.0 mgd), water used for agricultural irrigation (5.0 mgd), and water seeping from the Mine Water Surge Area ("MWSA") (1.2 mgd). The water balance matrix moisture component of 2.9 mgd is not a withdrawal of water for water use permitting purposes. The District's modeling of the impacts resulting from mine cut dewatering resulted in a finding of 2.34 MGD as opposed to the 3.7 mgd derived by CMI. For calculation purposes, rainfall is collected at the rate of 3,974 gallons per acre per day. CMI calculates that it will collect 3.1 mgd of rainfall, and use it in its recirculation system. The 3.1 mgd calculation is based on the amount of rain that will fall on 600 acres of mine water surge area, 80 acres of plant site, and two 50 acre mine cuts. CMI plans to mine 450 acres each year at the Pine Level Site over a period of 22 years. Runoff over disturbed areas on the CMI mine site must be captured, and will become part of the recirculation system. Assuming only one year of disturbed area during the permit term, CMI has failed to account for nearly 1.8 mgd in its water balance (450 acres x 3,974 gallons/acre/day). CMI plans to pump any rainfall collected from all disturbed areas to the mine water surge area (MWSA). CMI has not included any acres of disturbed area in its calculations of the amount of rainfall it will collect for the current permit. CMI has not submitted a mine plan. Without a mine plan, the number of disturbed acres cannot be determined. Because CMI's water balance does not include rainfall collected over disturbed areas, the water balance is incorrect. The rainfall collected from the disturbed areas will increase the amount of water that CMI will need to discharge or use for agricultural purposes. Excavation of the Mine Water Surge Area will cause dewatering of the surficial aquifer. No analysis was done of how much dewatering of the surficial aquifer will occur as a result of the excavation of the MWSA, or of the potential impacts to wetlands as a result of the dewatering activities. The District's one foot draw down presumption applies to dewatering as well as to groundwater pumping. The proposed dewatering setback from wetlands was set at 660 feet. The 660 foot setback distance is in lieu of mitigation if CMI wishes to mine within the setback distance, it will be required to implement mitigation procedures. Dewatering draw downs in the surficial aquifer as great as six and one-half to seven feet could occur on the CMI site at 660 feet from a mine cut under dry weather conditions. At 660 feet, the predicted draw down is nearly one and one-half feet using a mine pit depth of 26 feet, based on a three foot water table and a 29 foot average mine cut depth for the area expected to be mined during the term of the permit. Actual mine cut depths during the term of the permit would be as deep as thirty-seven feet which result in a draw down in the aquifer that is greater than one and on-half feet. Combining the dewatering calculations with the surficial aquifer draw downs resulting from CMI's planned well pumping from the intermediate and Floridian aquifers result in greater than predicted draw downs. CMI's water balance did not account for changes in water needs due to variability of the ore body. WATER QUALITY CMI has not demonstrated that the water quantities requested for the operation of the phosphate mine and beneficiation plant, and land reclamation and water handling will utilize the lowest water quality to the greatest extent practicable. Nevertheless, the Pine Level mine is innovative in comparison to other operating mines. It proposes to reduce its groundwater requirement by increasing the amount of recycled water used in the amine flotation process; employ an innovative sand/clay mixing technique for land reclamation, thus eliminating the need for conventional large, above-ground day settling areas or slime ponds; and use surplus water for irrigation of agricultural crops or pasture. CMI plans to mine the Pine Level Site for a period of 22 years. For phosphate mines, neither DNR, nor SWFWMD analyze impacts with respect to surface water during the mining process. For phosphate mines, no state agency looks at off-site surface water impacts from the standpoint of draw downs, with the possible exception of cities and counties. The District has not required CMI to submit an application for the management and storage of surface waters permit, since the District staff believes that phosphate mines are exempt from obtaining any MSSW permit from the District. A gap exists in the regulatory scheme for phosphate mines with respect to the reduction of surface water flows during the mining process if SWFWMD exempts phosphate mines from obtaining an MSSW permit. INTERFERENCE WITH EXISTING LEGAL USERS The City of North Port is an existing legal user of water. The City of North Port has a public water supply facility which draws its water from the Big Slough. The Big Slough normally gets a portion of its flow from high quality water in the surficial aquifer. CMI's proposed Pine Level phosphate mine is located in the watersheds which feed the Big Slough and the Peace River. In the initial years of the mine, virtually all of the collected rainfall will be diverted from the Big Slough watershed. No analysis has been done to see how dewatering might affect the City of North Port. Any significant reduction in flow to the City of North Port's facility during the low flow season will interfere with North Ports existing legal use of water. Diversion of 3.1 mgd of rainfall from the Big Slough will have an adverse impact on the City of North Port's water facility. The City of North Port is currently under a consent agreement with the Florida Department of Environmental Regulation because the water supplied by its facility violates drinking water quality standards for sulfates and total dissolved solids ("TDS") regularly during periods of low flow in the Big Slough. The MWSA, the plant area and the initial mining areas are primarily within the Big Slough drainage area. Seepage of 1.2 mgd from the MWSA will flow into the Big Slough. The only analysis done of the quality of the seepage from the MWSA was a rough analysis which showed that sulfates will likely be around 550 grams per liter. The legal standard for sulfates in drinking water is 250 grams per liter. Seepage from the MWSA will be high in total dissolved solids ("TDS") since a good portion of it was pumped from deep wells which have very high levels of TDS. No analysis was done of the potential of this seepage water to interfere with North Port's facility. Charlotte County is an existing legal user of water whose water supply is drawn from the Peace River downstream from the proposed CMI phosphate mine at Pine Level. Discharge of 5.0 mgd from the Pine Level mine could adversely affect Charlotte County's drinking water facility located on the Peace River. AGRICULTURAL USE CMI proposes to use 5.0 MGD of surplus water for irrigation of pasture grasses for cattle. CMI has not conducted any specific tests to determine the feasibility of using the discharge or the quality of the water that they plan to use for agricultural irrigation. The water for irrigation will be drawn out of the mine water surge area. The determination of whether the 5.0 mgd discharge can be used for agricultural irrigation has been postponed. The staff's position is that the proposed special conditions provide reasonable assurances that the discharge will comply with the requirements of the Basis for Review. WETLANDS Isolated wetlands occur throughout the CMI mine site. The isolated wetlands on the CMI property provide habitat for endangered and threatened species. Sandhill Cranes and Wood Storks, both threatened or endangered species, were sighted on the CMI property by wetlands experts during their site visit prior to the hearing. Small isolated wetlands on CMI property would be adversely affected by less than a one foot draw down. Wetland peat soils oxidize if exposed to the air. Oxidation results in subsidence of the wetland soils, which adversely impacts wetlands. Too much water as well as too little water can adversely impact wetlands. The combined effects of aquifer pumping and dewatering planned at the CMI site will adversely affect wetlands. No analysis was completed of the impacts to wetlands as a result of the combined effects of dewatering and pumping from the aquifer. No information regarding the normal range of wetland hydroperiods for preserved wetlands or other onsite unmined wetlands was introduced. No information was provided regarding the habitat functions provided by the wetlands on the CMI site either for threatened or endangered species or otherwise. ENVIRONMENTAL IMPACT The Applicant did not provide reasonable assurance that the water use will not cause unacceptable adverse impacts to environmental features on or off- site. The Applicant did not provide reasonable assurances that the water use will not have an adverse impact to surface water bodies such as lakes, ponds, impoundments, springs, streams, canals, estuaries or other water courses. The Applicant did not provide reasonable assurances that there will be no adverse environmental impact to wetlands, lakes, streams, estuaries, fish, and wildlife or other natural resources. The Applicant did not provide reasonable assurances that there will be no adverse impacts to the surface water system or vegetation as a result of groundwater withdrawal. The Applicant did not provide reasonable assurances that the water use will not have an adverse impact by altering or impairing the habitat of threatened or endangered species. The Applicant did not provide reasonable assurances that the projected draw downs will not result in any adverse impact to any protected or non-protected plant or animal species. The Applicant did not provide reasonable assurances that the water use will not have an adverse environmental impact to wetlands.

The Issue The issue concerns the entitlement of GJPS Lukas, Inc. to be granted a consumptive use of water permit from the St. Johns River Water Management District. See Chapter 373, Florida Statutes, and Chapter 40C-2, Florida Administrative Code.
Findings Of Fact On December 7, 1990, the Applicant applied for a consumptive use of water permit under application no. 2-127-0808AN as submitted to St. Johns. The Applicant asked that it be allowed to withdraw water from the Floridian aquifer to irrigate a 240 acre sod farm by the use of four wells and a pipeline ditch irrigation system. This was a new use. On January 9, 1991, St. Johns prepared a technical staff report recommending approval of the application. Petitioner was provided notice of this pending disposition on January 15, 1991 leading to his protest to the grant of the permit. Petitioner's property is adjacent to the Applicant's property. Petitioner has a well which he uses for domestic water needs which is in the vicinity of the proposed project. He also has a commercial fish operation with a number of fish ponds including fresh water ponds. Both these uses may potentially be affected by the proposed consumptive water use contemplated by the Applicant. St. Johns calculated that the irrigation of 240 acres of sod, by calculation using the modified Blaney-Criddle formula pertaining to evapotranspiration, calls for a maximum extraction of 169.4 million gallons a year. In any one month the amount withdrawn should not exceed 37.4 million gallons. The Floridian aquifer at the place where the Applicant proposes to draw water is capable of the production of 169.4 million gallons of water per year and 37.4 million gallons per month without promoting environmental or economic harm. Extraction of this water for purposes of irrigation is an acceptable arrangement in that no wastewater treatment plants are within a five mile radius of the site of the proposed use. Therefore it would not be economically, technically or environmentally feasible for the Applicant to use reclaimed wastewater as a source for its irrigation needs. The aquifer in that area is stable. There was no showing in the hearing by competent evidence that saline water intrusion problems now exist in the area of the proposed site of withdrawal. There was no showing that the withdrawal of as much as 169.4 million gallons per year would cause a saline water intrusion problem. The fields where the Applicant intends to apply the extracted water for irrigation purposes are surrounded by a system of ditches and water control structures to confine the water as applied to the sod and any mixing of that water with any surface or subsurface waters that are contributed by rain events. The ditches and control structures keep the water on the property and prevent flooding downgradient of the subject property. As a consequence flood damage on adjacent properties is not to be expected. On a related issue, the ditches and control structures will prevent water from discharging into receiving bodies of water and thereby degrading water in those receiving bodies such as the fish ponds operated by the Petitioner. The water quality of the Floridian aquifer will not be harmed by the activities of the Applicant in withdrawing this water. In the worse circumstances the well used by the Petitioner will be affected by the Applicant extracting the water from the aquifer to the extent of .25 to .4 drawdown in feet in the well the Petitioner uses. This is not a substantial impediment to the Petitioner's ability to withdraw needed water from the well he uses. The Floridian aquifer in the area in question is semi-confined. The four wells that would be used in withdrawing water for the Applicant's purposes will extract the water at 110 feet below the surface. Between that level and the surface are three confining areas of clay totaling approximately 40 feet in thickness. Those confining units of clay would protect the water at the surface when the Applicant withdraws water and induces a gradient. In particular, the nature of the stratification in the soils in the area in question and the topography are such that the Petitioner's fish ponds, when taking into account the distance between the Applicant's operation and those fish ponds, the clay confining units and the gradient between the Applicant's property and the Petitioner's fish ponds, would not lead to a reduction in the water levels of the Petitioner's fish ponds when the water was extracted by the Applicant. The proposed use by the Applicant would not require invading another use reserved by a permit issued from St. Johns. St. Johns has not established minimum levels or rates of flow for the surface water in the area where the Applicant proposes to extract the water. Nor has St. Johns established a minimum level for a water table aquifer or a minimum potentiometric surface water for an aquifer in the area where the Applicant proposes to extract the water. The surficial aquifer water table beneath the property where the Applicant intends to apply the extracted water should not be raised inordinately should the Applicant follow the best management practice as recommended as special condition No. 9 to the Consumptive Use Technical Staff Report pertaining to this project. Nonetheless if the water table beneath the Applicant's property were to be raised to a level which is too high or if the activities by the Applicant would result in excessive surface water runoff the ditches and water control structures that isolate the Applicant's property would prevent the water level in the Petitioner's fish pond from being increased by the Applicant's proposed activities. The application of the extracted water and the expected flow pattern of water applied to the surface and control of that water is set out in St. Johns' Exhibit No. 5 and described in the testimony of Jack Caldwell Lawrence, Jr., employee of St. Johns and an expert in geology and hydrology. See pages 61 and 62 of the transcript. Concerning water quality in the Petitioner's fish pond, it will not be affected by the Applicant's proposed activities in extracting the water. The gradients and distances between the Petitioner's fish pond and the Applicant's fields do not allow surface water or water in the surficial aquifer, which is groundwater above the confining clay unit, to flow from the Applicant's fields into the Petitioner's fish ponds. Again the ditches and control structures related to the project offer additional protection against a compromise to the water quality in the Petitioner's fish ponds. The Technical Staff Report on this project is an apt description of the project and the necessary conditions to granting a permit which would protect the public and environment. One modification has been made to that report and that modification is appropriate. It changes the intended disposition from one of allowing surface water from the onsite management system to be used as the primary irrigation supply with the Floridian aquifer serving as a supplementary source to one in which the Applicant would not use the onsite management system as a water supply source but would use the onsite management system simply as a discharge holding area.
Recommendation Based upon the facts found and the conclusions of law reached, it is, RECOMMENDED: That a Final Order be entered which approves the application for consumptive use of water subject to the conditions set forth in the Technical Staff Report, excepting the need to have the Applicant utilize water from the onsite management system as the primary source of irrigation of its sod. DONE and ENTERED this 4th day of November, 1991, in Tallahassee, Florida. CHARLES C. ADAMS, Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 4th day of November, 1991. APPENDIX TO RECOMMENDED ORDER The following discussion is made of the suggested facts set forth in the proposed recommended orders. Petitioner's Facts Paragraphs 1-6 are subordinate to facts found. Concerning Paragraph 7, Petitioner does not have standing to take issue with the quality of notice provided to other adjacent landowners. As to Paragraph 8, the witness had sufficient understanding of the location and nature of the surficial or sand aquifer and the clay confining units to have his testimony credited. As to Paragraph 9 the fact that the witness is unaware of the exact depth of the Petitioner's fish pond does not cause his testimony to be disregarded in deciding that the fish ponds would not be negatively impacted by the activities contemplated in this permit application. As to Paragraph 10, this proposed fact is inconsequential given the de novo nature of this proceeding. As to Paragraph 11, see discussion of Paragraph 7. As to Paragraph 12, it is rejected. As to Paragraph 13, that knowledge was not necessary in determining the outcome here. As to Paragraph 14, it is accepted in hypothetical terms, however, no showing was made that chlorides would increase in this instance and adversely affect the Petitioner's fish based upon the evidence adduced at hearing. As to Paragraph 15, the soil samples from Petitioner's property are inclusive and less reliable that the description of soil in the general area as set forth by the witness for St. Johns.

The Issue Whether Pasco County should be granted operating permits for Embassy Hills Wastewater Treatment Plant (WWTP) (Case 92-2489); Hudson WWTP (Case 92-2489); Hudson WWTP (Case 92-2488); and 8 Rapid Rate Infiltration Basins (RRIB) in Northwest Pasco County (Case 93-3091); whether the permit for RRIB should be granted to construct 10 RRIBs rather than 8 (Case 93-3641); whether these facilities can be operated without damage to the area potable and ground water systems; and whether the operating permit should include the provisions of a settlement agreement entered into between Matis, Pasco County and DER dated December 7, 1987. Whether the challenge to these permits was timely filed by Petitioner was resolved prior to the hearing and will not be revisited.
Findings Of Fact (Findings 1-80 below are from the prehearing stipulation submitted by the parties) The County is a political subdivision of the State of Florida, and owns and operates a wastewater collection, treatment, and disposal system in Pasco County, Florida. The Department is a state agency created pursuant to Section 20.261, Florida Statutes, and is responsible for protecting Florida's air and water resources in accordance with Chapter 403, Florida Statutes, and Chapter 17, Florida Administrative Code. Matis owns and resides at 11220 Denton Avenue, Hudson, Pasco County, Florida; her property is approximately 330 acres in size. In 1987, Matis filed a petition for formal administrative hearing against the Department and the County, in which she challenged the Department's proposed agency action to approve the County's applications for construction permits concerning the Embassy Hills WWTP (Permit Number DC51-128933) and the Hudson WWTP (Permit Number DC51-130307). That case was subsequently assigned DOAH Case No. 87-4781. Case No. 87-4781 was resolved by virtue of the 1987 Settlement Agreement. Matis, the County, and the Department were each parties to the 1987 Settlement Agreement. Paragraph 1(c) of the 1987 Settlement Agreement states: That the Respondent, Pasco County, will modify the permit application No. DC51-128933 as follows: . . . (c) The County agrees to reduce the number of ponds constructed at the Embassy disposal site located on Denton Avenue from fourteen (14) to nine (9) ponds by eliminating the five (5) most easterly ponds depicted on the County's construction plans; . . . The County subsequently modified its application for Permit Number DC51-128933 so as to delete the five most easterly ponds referred to in paragraph 1(c) of the 1987 Settlement Agreement. The Department subsequently issued Permit Numbers DC51-128933 and DC51- 130307, authorizing construction of the Embassy Hills and Hudson facilities, respectively. Permit Number DC51-128933 did not include authorization to construct the five ponds referred to in paragraph 1(c) of the 1987 Settlement Agreement. The County has not violated that portion of Section 2 of the Stipulated Settlement Agreement between the County, the Department and Matis which requires the County to construct a Floridian Aquifer and shallow aquifer monitor well cluster at the Hudson WWTP site at a location acceptable to Matis. The County has not violated that portion of Section 2 of the Stipulated Settlement Agreement which requires the County to monitor effluent discharged from the Hudson WWTP on a quarterly basis for the parameters specified in EPA Methods 601 and 602. The County has not violated Section 10 of the Stipulated Settlement Agreement. The County has not violated Section 13 of the Stipulated Settlement Agreement. The County has not violated Section 14 of the Stipulated Settlement Agreement. If the County and the Department comply with the 1987 Settlement Agreement, Matis will not be adversely affected by the proposed operation permits for the Embassy Hills and Hudson WWTPs (Permit Numbers DO51-203667 and DO51-203666). The County applied for Permit DO51-203666 (Hudson WWTP) on appropriate Department forms. The County applied for Permit DO51-203667 (Embassy Hills WWTP) on appropriate Department forms. The County's application for Permit DO51-203666 (Hudson WWTP) was certified by a professional engineer registered in the State of Florida. The County's application for Permit DO51-203667 (Embassy Hills WWTP) was certified by a professional engineer registered in the State of Florida. The County's application for Permit DO51-203666 (Hudson WWTP) was accompanied by a written certification by the permittee on Form 17-600.910(2) that an appropriate operation and maintenance manual is available at a specified location for the Hudson WWTP and the on-site percolation pond system. The County's application for Permit DO51-203667 (Embassy Hills WWTP) was accompanied by a written certification by the permittee on Form 17- 600.910(2) that an appropriate operation and maintenance manual is available at a specified location for the Embassy Hills WWTP and each associated disposal site. The Hudson WWTP is a Type I facility. The Embassy Hills WWTP is a Type I facility. The Hudson WWTP is enclosed with a fence or otherwise designed to discourage the entry of animals and unauthorized persons. The Embassy Hills WWTP is enclosed with a fence or otherwise designed to discourage the entry of animals and unauthorized persons. The Hudson WWTP's on-site percolation pond system is a Type I facility. The Denton Avenue Percolation Pond System is a Type I facility. The proposed Northwest RRIBs project is a Type I facility. The Hudson WWTP's on-site percolation pond system is a rapid rate land application system, as that term is defined in 17-610.510. The Denton Avenue Percolation Pond System is a rapid rate land application system as that term is defined in Rule 17-610.510, Florida Administrative Code.

On December 23, 1992, the Department's Intent to Issue Permit Number DC51-214670 was published in the Pasco Times. On December 23, 1992, Matis saw and read an Intent to Issue Permit Number DC51-214670 published in the Pasco Times. Matis' property receives wastewater service from a septic tank located on the east side of her house. Matis' septic tank was installed in 1965, and it has not been replaced or serviced since that time. Since Matis' septic tank was installed in 1965, she has never had any wastewater removed from it. Matis is not aware of any water quality or contamination problems on her property. All water quality analyses which Matis has performed on her well water has revealed no contamination. Matis has never experienced an inability to pump water from her wells. Matis is not aware of any land collapse or sinkhole problems on her property. Matis' property includes approximately 240 to 250 acres of planted pine trees. Matis has had cattle operations on her property since around 1967. Presently, Matis has approximately 30 head of cattle on her property. Matis is not aware of any adverse affects to her agricultural operations caused by the historical operations of the County's wastewater facilities. Matis is not aware of any adverse affects to her property caused by the historical operations of the County's existing wastewater facilities. Matis is not an expert in the field of engineering, geology, hydrology, hydrogeology, wastewater system design, wastewater system operation, wastewater treatment methods, wastewater disinfection, sinkhole formation, biology, botany, ecology, groundwater modeling, water quality analysis, or air quality analysis. By letter dated November 17, 1992, Attorney William Deane requested the Department to provide his client (Respondent Marie Cook Matis), through his office, actual notice of the proposed agency action regarding the Northwest RRIBs construction permit application. On December 22, 1992, the Department furnished Matis (via her attorney, Mr. Deane) a telephonic facsimile copy of an Intent to Issue Permit Number DC51-214670 for the Northwest RRIBs. On December 23, 1992, the County (as permit applicant) had an Intent to Issue Permit Number DC51-214670 published in the Pasco Times. On December 23, 1992, the Pasco Times was a newspaper of general circulation in the area affected by the Northwest RRIBs project. On December 29, 1992, the Department's Southwest District Office hand delivered a copy of the Intent to Issue Permit Number DC51-214670 to Matis. On or about January 5, 1993, Mr. Deane's associate (i.e., Attorney Charles Hinton) sent the Department's attorney, Francine Ffolkes, a letter which stated: RE: Construction Permit Number DC51-214670 Northwest Pasco Rapid Infiltration Basins Notice of Intent Dear Ms. Ffolkes: This is to confirm our conversation this morning regarding the above referenced permit. Pursuant to that conversation, it is our understanding that Ms. Matis received actual notice of the above-referenced Notice of Intent on December 29, 1992. Accordingly, Ms. Matis has until January 12, 1993 to file a motion or objection to this permit. If this is in anyway incorrect, please contact my office immediately. Sincerely, /s/ Charles D. Hinton Charles D. Hinton Sent by facsimile this 5 day of January, 1993. Mr. Hinton did not send a copy of the foregoing letter to the County or otherwise advise the County regarding his conversation with Ms. Ffolkes. On January 12, 1993, Matis' Petition for Formal Administrative Hearing concerning the Northwest RRIBs construction permit (Permit Number DC51-214670) was received by the Department's Office of General Counsel. Matis' sole objection to the proposed operating permits for Embassy Hills WWTP and Hudson WWTP is that they do not incorporate the terms of the 1987 Settlement Agreement. No evidence was submitted that Pasco County is not complying with the terms of this settlement agreement or that the operation of these plants will in any wise affect Matis' property. The evidence is unrebutted that these plants have been operating for over two years without violations and that the effluent from these plants meets all statutory and regulatory requirements. So far as practicable the treated wastewater from these plants (and other WWTPs operated by Pasco County) is reused for irrigating golf courses, orange groves, and for residential irrigation. It is only during rainy periods when irrigation is not called for that this effluent is discharged through the infiltration basins. Both of these plants are Type I conventional activated sludge with anoxic denitrification wastewater treatment plants and meet the limitations for ph, BOD, nitrates, chlorine, sodium and dissolved solids contained in the proposed operating permit conditions. Although these operating limits for BOD, TSS and nitrates in the proposed operating permit exceed those in the construction permit and the Settlement Agreement, the proposed permit meets all statutory and regulatory requirements which the Department is called upon to enforce. The actual operation of these WWTPs meet the elevated standards of 15BOD, 5TSS, and 10 nitrates contained in the construction permit and Settlement Agreement. Accordingly, Pasco County is in compliance with the Settlement Agreement. Pasco County, like much of central Florida, is a Karst area subject to sinkholes. To insure the proposed rapid rate infiltration basins will not constitute a threat to the aquifer below the sites selected for these RRIBs, transects were taken, and the U.S. Department of Agriculture, Soil Conservation Service was engaged to conduct ground penetrating radar (GPR) studies of these areas. For any of those areas showing a possibility of below ground caverns or other evidence of potential sinkhole, borings were taken to determine the conditions below the surface of the ground. The GPR survey coupled with these "truth" borings revealed that the sites selected for these RRIBs are safe and appropriate for use as infiltration basins to receive the treated effluent from these plants. Five of the proposed RRIBs located closest to Matis' property were removed from the 1987 Pasco County construction permit application as a result of the Settlement Agreement. That Agreement did not preclude Pasco County from later seeking authorization to construct these RRIBs. It is the construction of these five RRIBs that Matis here protests. Matis' property is upgrade from these RRIBs and from the WWTPs here involved. Accordingly, it is virtually impossible for effluent from these RRIBs to reach Matis' property or her potable water well. In fact, the most likely source of contamination of Matis' potable water well is Matis' septic tank which is located upgrade from her potable water well. Pasco County currently reaches about 80 percent utilization of the effluent from its WWTPs as reused water for irrigation of golf courses, orange groves, residences, etc. It is seeking 100 percent utilization of its treated effluent for reuse. This will conserve potable water from the aquifers and better enable Pasco County to supply adequate potable water to its increasing population. To accomplish better reuse of treated effluent from its WWTPs Pasco County intends to install a master reuse plan wherein wastewater effluent from all the WWTPs in the county would feed into a single looped system. This system would intermingle all of the wastewater and then dispose of this wastewater at all of the county's reuse points. When the reuse points cannot absorb the wastewater due to rain or high water conditions, the wastewater would be discharged into the RRIBs. Although the construction of the additional five RRIBs to which Matis objects exceed the minimal disposal capacity required by the Department, having this excess disposal capacity reduces the possibility of contamination of surface waters from the treated wastewater from these WWTPs.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that Permit Number DO51-203666 be issued for the operation of Hudson WWTP; that Permit Number DO51-203667 be issued for the operation of Embassy Hills WWTP; and that Permit Number DC51-214670 be issued for construction of the ten Northwest Pasco County RRIBs. DONE AND ENTERED this 22nd day of October, 1993, in Tallahassee, Leon County, Florida. K. N. AYERS Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 22nd day of October, 1993. APPENDIX TO RECOMMENDED ORDER, CASE NO. 92-2488 Proposed findings submitted by Petitioner are accepted except as noted below. Those neither accepted nor noted below were deemed unnecessary to the conclusions reached. 16. Rejected in part. Matis saw the Notice of Intent to issue the permits here at issue published in the Pasco Times on December 23, 1992, and on December 22, 1992, Matis' attorney was furnished a facsimile copy of this notice. A copy was personally delivered to Matis by a DER representative on December 29, 1992. 24. Rejected. 30-32. Rejected as irrelevant. Rejected. DER adopted the proposed findings submitted by Pasco County. Those findings are accepted. Proposed findings submitted by Pasco County and not included in the Hearing Officer's findings were deemed unnecessary to the conclusions reached largely because Petitioner Matis challenged only the refusal of DER to include the provisions of the Settlement Agreement in the operation permit for the WWTPs and to grant construction permits for the five RRIBs withdrawn from the petition in 1987 as a result of the Settlement Agreement.

The Issue Whether Respondent illegally and without permit removed a drain field and now has an unapproved septic system on a structure intended for human occupancy, and if so, what is the appropriate correction and fine.
Findings Of Fact On June 17, 2009, Department of Health employee Stephanie Daughtery was driving down Lake Erie Road in Groveland, Florida, past Respondent’s residence located at 6345 Lake Erie Road, when she noticed the sand mound that had held the septic system drain field for Respondent’s home was no longer there. Ms. Daughtery was familiar with the mound that had been located on Respondent’s land because, in her capacity as Petitioner’s employee, she had previously conducted a stabilization check on the mound. A sand mound for Respondent’s drain field was required under applicable law and regulations because, during the rainy season, the water table in the area of Respondent’s home was ten inches “below grade,” which means that the water level was just ten inches below ground level during the rainy season. Therefore, a sand mound was necessary for proper filtration of the raw sewage (effluent) entering the septic system. A septic system without a proper drain field will allow effluent to escape and constitute a public health risk. Upon returning to her office at the Lake County Health Department that same afternoon, Ms. Daughtery told her supervisor, Elias Christ, of her observation. One of Respondent’s neighbors had already reported the situation involving the removal of Respondent’s drain field to Mr. Christ. The next day, one of Petitioner’s inspectors, Daniel McColley, went out to Respondent’s property and met with Respondent. Respondent told the inspector that the mound which had been removed was just a pile of dirt. Contrary to Respondent’s assertion, the mound that was removed had been part of the drain field for Respondent’s septic system. Respondent was responsible for the removal of the mound and drain field. On June 22, 2009, Petitioner sent, by certified mail to Respondent, an Official Notice to Abate a Sanitary Nuisance, which advised: On 06/18/2009 an onsite investigation disclosed that an approved drain field had been removed and either not replaced or replaced without a permit, which violates Chapter 386.041(1)(a)(b)(e)(f) of Florida Statutes. You are hereby directed to contact this Department within 24 hours of this notice to discuss corrective action. A repair permit must be applied for and a system installed with Department approval. Approximately a week to ten business days later, after Respondent had failed to apply for a permit, Petitioner again sent an inspector to inspect Respondent’s septic system and found it to be still in nuisance condition, with no drain field. In addition to being in an area with water just ten inches below grade during rainy season, Respondent’s property is adjacent to a lake. Since the sand mound was removed, there is no proper drain field and Respondent’s septic system is a sanitary nuisance. As explained by Mr. Christ at the administrative hearing, Respondent’s septic system without a drain field is a threat to public health: Because we have untreated sewage that we have no idea where its going to. He has - - he also has a lake behind his property, so we don’t know if he’s somehow plumbed it into dumping into the lake or if it’s just dumping out on the ground. Respondent told one or more of Petitioner’s employees that he had connected his septic system to an old septic tank in an adjacent house on the property. He did not, however, obtain a permit to do so, and the old system was inadequate, without renovation, to handle the additional effluent. In addition, although Respondent further claimed that a septic contractor had pumped out his old system, Respondent would not give the name of the alleged contractor. On July 6, 2009, Petitioner sent, by certified and regular mail, a “Notice of Intended Action” to Respondent which advised: You have not yet come to apply for a permit to replace this system you removed. Failure to do so will result in legal action and possible revocation of your CO and further Lake County Code Enforcement Action. Please contact this office within 24 hours of receipt of this notice to discuss a corrective action plan at (352) 253-6130 or FAX (352) 253-6133. If this sanitary nuisance is not abated and a proper septic tank repair permit applied for and work is completed in a satisfactory manor, inspected by this department, you may be subject to fines up to $500.00 per day authorized therein accordance with the authority outlined in Section 381.0065(5) Florida Statutes(F.S.). If you have further questions please call Elias Christ or Russ Melling at 352-253-6130. Respondent came into the Lake County Health Department on July 22, 2009, and was given an application and a checklist for permitting the repair of his septic system. During that visit, Respondent told Mr. Christ that the cows had destroyed the mound. He also told Mr. Christ that he had been trying to sell his house and that the mound had been an eye-sore that was interfering with the sale. Later, in a telephone conversation with Mr. Christ, Respondent advised that he really did not have the money to replace the drain field, but he would be happy to have it replaced if the county would pay for it. By September 25, 2009, Respondent still had not applied for a permit or repaired his septic system. On September 25, 2009, Petitioner issued a Citation for Violation Onsite Sewage Program/Sanitary Nuisance to Respondent (Citation). Part 1 of the Citation alleges that Respondent is in violation of Section 386.041(a), (e), and (f), Florida Statutes, and Florida Administrative Code Rules 64E- 6.001(2) and 64E-6003(1), on the grounds that Respondent “[h]as illegally and without any permits removed his drain field and now [has] an unapproved system on a structure intended for human occupancy.” The Citation further provides: The person named in this citation is hereby ordered to correct the violation(s) listed in Part 1 within 10 days [from] the service of this citation. The person identified in this citation is hereby directed to pay a fine in the amount of $500 plus $100 per [day] additionally from receipt of this citation until the drain field is repaired legally for the violations listed in Part 1. Payment must be made to the LAKE County Health Department within 21 days of the receipt of this citation, or you may choose the option listed on Part 9. Part 9 of the Citation provides for a request for an administrative hearing and warned Respondent that if he requested a hearing and then failed to appear to contest the citation, he would waive the right to contest the citation. By his signature dated October 1, 2009, in Part 9 of the Citation, Respondent requested an administrative hearing. This administrative hearing followed. Respondent failed to attend or present any evidence at the final hearing. Prior to the hearing, Respondent indicated to Petitioner’s counsel that he was not financially able to put the drain field back the way it was and that he did not see the point in appearing at the administrative hearing. On the other hand, the evidence presented by Petitioner at the administrative hearing, as outlined in the findings above, clearly and convincingly demonstrated that Respondent removed a mound and drain field required by applicable law and regulations for his septic system, and that Respondent’s septic system has not been repaired as required to comply with the law.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Health enter a Final Order finding that Respondent illegally and without permit removed a drain field and now has an unapproved septic system on a structure intended for human occupancy, and ordering Respondent to pay a fine in the amount of $500.00 for deposit into the county health department trust fund, obtain a septic system repair permit, and effect repairs on his septic system to correct the violations of Section 386.041(a)(e)(f), Florida Statutes, and Florida Administrative Code Rules 64E-6.001(2) and 64E-6.003(1), within forty-five (45) days from the Final Order. DONE AND ENTERED this 2nd day of April, 2010, in Tallahassee, Leon County, Florida. S JAMES H. PETERSON, III Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 2nd day of April, 2010.
The Issue The parties have raised myriad issues hare. Petitioner has alleged being capriciously and arbitrarily denied its permit because similar treatment plants have been licensed nearby. The parties disagree over whether local Lake County Pollution Control Board rules are applicable to Petitioner's plant. If the rules are applicable, they disagree over their interpretation. The parties further disagree over whether Petitioner has pending an application for a waste water treatment plant operating permit. It is this last issue which is discussed below because it is dispositive of the case.
Findings Of Fact Petitioner operates a waste water treatment plant in Lake County, Florida which serves four motels at the intersection of U.S. Highway 27 and SR 19 immediately to the south of Interchange 27 on the Florida Turnpike. On October 27, 1972, DER issued a construction permit to Petitioner to construct the plant at a design capacity of 250,000 gallons per day (gpd). The treated effluent was proposed to be discharged via a spray irrigation system to the ground water on Petitioner's site. The plant has never operated at capacity. Its normal volume has ranged from between a low of 40,000 gpd to a peak of 140,000 gpd. Petitioner's plant is situated on a 12.5 acre site over a clay hard pan. The hard pan which is immediately below the ground surface prevents adequate percolation of the plant's effluent down to the underlying ground water. During periods of heavy rain the effluent from the plant has breached a retaining dike and flowed directly into a marsh area known as the Little Everglades to the north. Petitioner has submitted four permit applications to the Department. The first, submitted in September of 1972 was for the construction permit already mentioned. The next applications dated October 22, 1973, was for an operation permit. The application indicated that there would be no discharge to surface waters but there would be a discharge to ground waters. The application also indicated that the availability of space for the expansion of the plant was limited to the site at that time. Petitioner later purchased additional land not reflected in this application. The operation permit was never granted by the Respondent. As stated by Mr. Potter, President of Lake County Utilities, Inc., "In the fall of 1973, I made an application as engineer for the utility company to the Florida DPC [Department of Pollution Control] and to Lake County for an operation permit. That permit was denied by the Department on the ground that we had not satisfied Lake County as to the total containment of our effluent." Subsequently on August 30, 1976, Petitioner submitted a construction permit application to DER for permission to add a 1.32 acre oxidation-polishing pond, to regrade and regrass the existing spray irrigation field, to construct a 0.40 acre denitrification pond and to add a nutrient uptake. No increase in the design capacity was proposed. On that application Petitioner indicated that there would be a discharge to the surface waters of the state. In answer to that part of the application which asked for proposed drainage path of the effluent Petitioner stated, "From treatment plant to 'on-site' ponds to 'on-site' grassy pond and marsh would overflow to ajacent Florida DOT [Department of Transportation] borrow pit: thence via developed drainage waste to the 'Little Everglades' swamp: then, via developed canal and ditches and through natural ponds and marshes to 'Little Lake Harris' and ultimately the Atlantic Ocean." This permit was denied by DER because the Lake County Pollution Control Board did not approve the plan. Finally on September 29, 1978, Petitioner applied for another construction permit. Thee construction would include: Construction of storm water control structures and culverts: Regrading of water and sewer plant sites; Construction of percolation pond "A" and enclosing dikes; and Construction of percolation pond "B" and enclosing dikes. This application was made in response to advice from DER that Petitioner's plant should be in a no discharge condition in order to comply with Lake County Pollution Control rules. On November 2, 1979, the Department issued a Letter of Intent to deny the last permit application because the application was deemed to be incomplete and because the further data which DER requested was not provided. In response to DER's intent to deny the construction permit Petitioner on November 20, 1979, filed its Petition for an Administrative Hearing. Petitioner does not now intend to construct the proposed facilities for which it requested the construction permit in September of 1978. The following colloquy is from the final hearing. Mr. Stephens Have you-- Can you describe briefly the nature of the changes proposed in your 1978 construction permit application? Mr. Potter 1978 construction permit application on nominally the five acre parcel to create a diked pond or lake. Mr. Stephens Uh-huh. Mr. Potter Solely that. The part on the nominally two and a half acre parcel, give or take, was to create a deep percolation pond in which I proposed digging through the clay to the sand and shell below. Mr. Stephens Uh-huh. Mr. Potter So that waters that entered that pond, A, because of its depth, would denitrify and release nitrogen contents to the atmosphere; and, the water would, because of its hydraulic head in relation to the soil below, would push its way into the soils below. Mr. Stephens Uh-huh. Mr. Potter But in the event I could not dispose of the water through that form of percolation, it would overflow into the five acre diked area. And thereby I hoped to satisfy Lake County and the D.E.R. and solve this lingering festering problem. Mr. Stephens Uh-huh. You are the Petitioner in this case. Is it your desire or intention to complete those. . .that construction? Mr. Potter Now that I have been made aware of the law, the law of Chapter four oh three, the rules of Florida D.E.R. and become clear as to the ordinances adopted by the County Commission and the Lake Pollution Board of Lake County as to Class 3-B waters, I have no intention of squandering my money, and, in effect, the money of my customers, in such a wasteful pursuit. Mr. Stephens So you're saying here under oath you don't intend to perform that work even if granted a permit? Mr. Potter Not shy of a court order. As the result of Mr. Potter's testimony on behalf of the Petitioner at the final hearing, it is found that Petitioner has withdrawn its September 1978 application for a construction permit. There is not now pending before the Department of Environmental Regulation a valid permit application for the Petitioner to operate its waste water treatment plan. On May 9, 1980 Lake County Utilities, Inc. served Petitioner's Fourth Interrogatories to Respondent which asked by Interrogatory 10: Please state when and by whom the Department of Environmental Regulation has caused field studies to be made and samples to be taken out of the waters of Lake County (and specifically the geographical vicinity of U.S. 27 - S.R. 19 - Fla. Turnpike) periodically and in a logical geographic manner so as to determine the levels of water quality of the waters as such studies and sampling is within the powers and duty of the Department as mandated by the Florida Legislature in Chapter 403 of the Laws of Florida. (emphasis in original) The Department responded: 10. The Department conducts sampling in the waters of Lake County in conjunction with individual permit applications and not on a systematic basis throughout the County. Respondent objects to this interrogatory as being irrelevant to this proceeding in that the subject permit was not denied on the basis of anticipated water quality violations, but rather, as a result of the pollution control ordinances of Lake County, Florida, which prohibit any discharge to surface waters from the subject facility, and which the Department is required to enforce pursuant to Section 403.182(6), Florida Statutes.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it Is RECOMMENDED: That the State of Florida, Department of Environmental Regulation enter a Final Order dismissing the Amended Petition for Administrative Hearing without prejudice, however, to the filing of a new application by Petitioner for a waste water treatment plant operating permit. DONE and RECOMMENDED this 12th day of May, 1981, in Tallahassee, Florida. MICHAEL P. DODSON Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 12th day of May, 1981.
The Issue The issue in this case is whether the Variance Review and Advisory Committee and the Department of Health had just cause to disapprove Petitioner's application for a variance.
Findings Of Fact The Department of Health (DOH) is the agency responsible for oversight of the on-site sewage treatment and disposal systems program and the Variance Review and Advisory Committee which meets monthly to recommend agency action on variance requests pursuant to Chapter 381, Florida Statutes. In August 1999, Petitioner applied to the DOH for a second variance to extend a variance previously granted in June 1999, to use an existing septic system for six months. Petitioner's application for the second variance stated that county sewer would be available in 2001, and she would be required to hook into the sewer. Therefore, Petitioner wanted an extension to continue using the existing undersized septic system until the sewer was available. She also attached water usage records for June 1998 through July 1999, for her property. Petitioner owns the commercial property served by the septic system and located on Howland Boulevard in Deltona, Florida. The property consists of a strip mall with five offices and one restaurant. The property originally contained six office spaces in 1990, when Petitioner applied for a permit to install a septic system to handle the building's sewage flow. See Petitioner's Exhibit No. 1. Petitioner was granted a construction permit for the septic system on August 14, 1990, which contained the statement: "no food service operations permitted in this building." Prior to May 1999, Petitioner leased an office in her commercial property to Milagros Martinez to operate a sandwich shop. Ms. Martinez applied to DOH for approval to use Petitioner's existing septic system to handle her sandwich shop sewage, and was denied because of increased water use and septic system demands of a restaurant. Petitioner's septic system contains a 750-gallon tank with 162 square feet of drainfield. In order to handle the additional sewage generated by the sandwich shop, the Florida Administrative Code requires a 1350-gallon tank and a drainfield of 787 square feet. There is enough room on Petitioner's property to install a separate septic system to handle the sewage generated from the sandwich shop. Petitioner applied to DOH for her first variance in May 1999, requesting to utilize the septic system to handle the waste from the sandwich shop. Petitioner appeared before the DOH Variance Review and Advisory Committee in June 1999. The committee recommended, and DOH concurred, to approve the first variance with four provisos. See DOH Exhibit No. 2. The four provisos were: The applicant shall obtain and maintain an annual onsite sewage treatment and disposal system operating permit in accordance with subsection 64E-6.003(5), F.A.C. The owner shall maintain an annual contract with a licensed septic tank contractor to inspect and service the onsite sewage treatment and disposal system at least once per month or more frequently as necessary. This variance allows operation of the sandwich shop for no more than six months. During that six months, the applicant shall take all necessary steps to increase the capacity of the system to accommodate the additional 230-gallon sewage flow from the sandwich shop. At the end of the six months, the system shall be in compliance or the sandwich shop shall be closed and remain closed until compliance is achieved. The four provisos were additionally explained to Petitioner in a letter dated July 14, 1999, from Sharon Heber, Director of the DOH Environmental Health Division. See DOH Exhibit No. 1. Petitioner accepted the provisions of the first variance on July 20, 1999. See DOH Exhibit No. 4. Petitioner does not have a current annual on-site sewage treatment and disposal system operating permit as required by the first proviso. Petitioner did not contract with a licensed septic tank contractor to inspect and service her system at least once per month as required in the second proviso. Petitioner called a contractor to inspect her system four times in the six-month period since the first variance was granted. Within six months, Petitioner did not take the necessary steps to increase the capacity of her septic system to handle the additional flow as required by the third proviso of the first variance. The system is not in compliance and the sandwich shop is not closed as stated in the fourth proviso. In August 1999, Petitioner filed for a second variance requesting that the first variance be extended until year 2001. That is the date the county plans to install a sewer line on Howland Boulevard in Deltona, which will serve her commercial property. She submitted a letter from the Volusia County Public Works Service Center stating that the "sewer service is planned to be available sometime in the year 2001." See Petitioner's Exhibit No. 4. The Variance Review and Advisory Committee considered Petitioner's request at their September meeting. The variance committee unanimously denied Petitioner's request for a second variance. The Petitioner's system was not designed to handle an increased amount of sewage flow, and that it would eventually collapse or fail. The committee's approval of the first variance was to allow Petitioner adequate time to install the necessary septic system for the restaurant, and not put Petitioner in the position of telling her tenant she could not open her restaurant. See DOH Exhibit No. 5. When Petitioner's existing system fails, sewage will pond on the ground. The ponding fluid will consist of raw sewage. The leaking/ponding sewage may seep into the groundwater and then into drinking water aquifers. In the right conditions, this pollution can cause the spread of waterborne diseases such as typhoid and cholera, or viral infections, such as hepatitis A or polio.
Recommendation Based upon the findings of fact and conclusions of law, it is RECOMMENDED: That the Department of Health enter a final order affirming the decision of the Variance Review and Advisory Committee and the Department of Health to disapprove Petitioner's second variance application.

Findings Of Fact At all times pertinent to the issues herein, Respondent, Cargill, a Delaware corporation authorized to do business in Florida which owned and operated a phosphate mine near Fort Meade, located in Polk County Florida. Petitioner, Gloria Elder, owns residential property adjoining the Fort Meade Mine on which she maintains an individual water well for domestic and other purposes. The Respondent, District, has the responsibility for regulating the consumption and conservation of ground and surface water within its jurisdictional limits, including the well in question. For a period prior to December, 1990, Cargill had been operating under consumptive use permit No. 202297.04, issued by the District, which provided for average daily withdrawals of 12.0 MGD from wells on its property. In addition to the 12.0 MGD, Cargill also was utilizing an additional 3.3 MGD for mine pit and surficial aquifer dewatering activities which did not have to be reflected in the permit but which were lawful uses. In December, 1990, Cargill submitted its application to renew the existing water use permit with a modification including the 3.3 MGD previously being used but not officially permitted. No additional water would be drawn from the permitted wells as the newly applied for 15.3 MGD was the total of the 12 MGD and 3.3 MGD previously permitted and lawfully used. After reviewing the additional information requested of Cargill pertaining to this application, the District published its Notice of Proposed Agency Action for approval of the permit. The proposed permit authorizes withdrawal of the amount requested in the application, 15.3 MGD, the exact same amount actually withdrawn under the prior permit. As a part of the proposed permit the District imposed two special conditions. These conditions, 12 and 13, require Cargill to conduct its dewatering activities no closer than 1,500 feet to any property boundary, wetlands, or water body that will not be mined or, in the alternative, to mitigate pursuant to conditions 12 and 13 any activities conducted within the 1,500 foot setback. There are no reasonable alternatives to Cargill's request. The mining process in use here utilizes a water wash of gravel-size phosphate ore particles out of accompanying sand and clay. The water used for this purpose is recycled and returned to the washer for reuse. The resulting phosphate ore mix, matrix, is transported with water in slurry form to the refining plant. This system in the standard for phosphate mining in the United States. Once at the plant, the slurry is passed through an amine flotation process where the sand and phosphates are separated. This process requires clean water with a constant Ph balance and temperature which can be retrieved only from deep wells. Even though the permit applied for here calls for an average daily withdrawal of 15.3 MGD, typically the Cargill operation requires about 10.08 MGD from deep wells. This is a relatively standard figure within the industry. Approximately 92 percent of the water used at the site in issue is recycled. However, recycled water is not an acceptable substitute for deep well water because it contains matters which interfere with the ability of the chemical reagents utilized in the process to react with the phosphate rock. Therefore, the quantity sought is necessary and will support a reasonable, complete mining operation at the site. The Cargill operation is accompanied by a strenuous reclamation operation. Land previously mined near the Petitioner's property has been reclaimed, contoured, re-grassed and re-vegetated. This project was completed in 1990. No evidence was introduced showing that Cargill's operation had any adverse effect on the Elders' well. Water samples were taken from that well at the Petitioner's request in May, 1991 in conjunction with the investigation into a previous, unrelated complaint. These samples were submitted to an independent laboratory for analysis which clearly demonstrated that the minerals and other compounds in the water from the Petitioner's well were in amounts well below the detection level for each. Only the iron level appeared elevated, and this might be the result of deterioration of the 18 year old black iron pipe casing in the well. Another possible explanation is the fact that iron is a common compound in that part of the state. In any case, the installation of a water softener would remove the iron, and there is no indication the water would have any unacceptable ecological or environmental impacts in the area either on or off the site. No other residents in the area have complained of water quality problems. Petitioner claims not only that Cargill's operation would demean her water quality but also that its withdrawal will cause a draw down in the water level in her well. This second matter was tested by the District using the McDonald-Haurbaugh MODFLOW model which is well recognized and accepted within the groundwater community. The model was applied to the surficial, intermediate, and upper Floridan aquifers and indicated the draw down at the property boundary would be less than one foot in the surficial aquifer and less than four feet in the intermediate aquifer. The model also showed the draw down at the Petitioner's well would be less than three feet, which is well within the five foot criteria for issuance of a consumptive use permit under the appropriate District rules. This evidence was not contradicted by any evidence of record by Petitioner. All indications are that the water use proposed is both reasonable and beneficial, is consistent with the public interest, and will not interfere with any existing legal use of water.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is, therefore recommended that WUP Permit No. 202297.05 be renewed as modified to reflect approval of 15.3 MGD average daily withdrawal. Jurisdiction will remain with the Hearing Officer for the limited purpose of evaluating the propriety of an assessment of attorney's fees and costs against the Petitioner and the amount thereof.

The Issue The issues set forth in DOAH Case No. 84-3810 concern the question of whether the State of Florida, Department of Environmental Regulation (DER) should issue a permit to Homer Smith d/b/a Homer Smith Seafood (Homer Smith) to construct a wastewater treatment facility which is constituted of a screening mechanism, dissolved air flotation treatment system, sludge drying bed, pumping station and subaqueous pipeline. In the related action, DOAH Case No. 84-3811, the question is raised whether DER should issue a dredge and fill permit to Homer Smith for the installation of the aforementioned pipeline along submerged lands in Trout Creek, Palmo Cove and the St. Johns River.
Findings Of Fact Introduction and Background In 1982, Homer Smith, under the name of Homer Smith Seafood, established a calico scallop processing facility in the vicinity of the intersection of State Road 13 and Trout Creek in St. Johns County, Florida. From that point forward, Smith has owned and operated the processing plant. His plant adjoins Trout Creek, which is a tributary to the St. Johns River. Both Trout Creek and the St. Johns River are tidally influenced waters that are classified as Class III surface waters under Rule 17-3.161, Florida Administrative Code. The processing undertaken by Smith's operation at Trout Creek contemplates the preparation of the scallops for human consumption. In particular, it involves the purchase of calico scallops from Port Canaveral, Florida, after which the scallops are transported by refrigerated trucks to the processing plant. They are then unloaded into metal hoppers and directed into rotating tumblers which separate out the scallops from sand, mud and other extraneous material. The scallops are placed in a steam tumbler that removes the shells and then passed through a flow tank that washes away sand, grit and shell particles. The scallops are next passed through eviscerators. These eviscerators are long tubes of aluminum with roughened surfaces that pull the viscera off of the scallops. The detached scallops are then sent along a conveyor belt, with scallops in need of further cleaning being picked out and sent to a second eviscerator. The eviscerated scallops are then chilled and packed for marketing. It is the viscera and wastewater associated with this material that is the subject of permitting. Homer Smith is one of about six automated scallop processing plants located in Florida. Two other plants are within St. Johns County, on the San Sebastian River in St. Augustine, Florida. Three other plants are located in Port Canaveral, Florida. When Smith commenced his operation of the scallop processing plant in the summer of 1982, he discharged the scallop processing wastewater into an area described as a swamp with an associated canal which connected to Trout Creek. By the fall of 1982, Smith had been told by representatives of the Department of Environmental Regulation that to operate his facility with the discharge would require a permit(s) from DER. At the time of this discussion, automatic scallop processing was an industry for which appropriate wastewater treatment alternatives had not been specifically identified by the Department of Environmental Regulation or the United States Environmental Protection Agency. This was and continues to be the case as it relates to the promulgation of technology-based effluent limitations designed for calico scallop processors. This circumstance is unlike the situation for most other industries for which DER has established technology-based effluent limitations. To rectify this situation, Florida Laws 85-231 at Section 403.0861, Florida Statutes, requires DER to promulgate technology-based effluent limitations for calico scallop processors by December 1986. In the interim, consideration of any permits that might be afforded the calico scallop processors by the exercise of DER's regulatory authority must be done on a case-by-case basis, when examining the question of technology-based effluent limitations. DER sent a warning letter to Smith on April 20, 1983, informing the processor that discarding its wastewater into Trout Creek without a DER permit constituted a violation of state law. After the warning letter, scallop harvesting declined to the point that by mid-June of 1983 the plant had closed down, and it did not reopen until the middle part of September 1983. Upon the recommencement of operations, DER issued a cease and desist notice and ordered Smith to quit the discharge of wastewater from the facility into Trout Creek. On the topic of the cease and desist, through litigation, Smith has been allowed the right to conduct interim operation of his business which involves direct discharge of wastewater into Trout Creek, pending assessment of wastewater treatment alternatives and pursuit of appropriate DER permits. 1/ When Smith filed for permits on April 10, 1984, he asked for permission to dredge and fill and for construction rights pertaining to industrial wastewater discharge into the St. Johns River. The application of April 10, 1984, involved the installation of a wastewater treatment system and an associated outfall pipeline to transport treated wastewater to the St. Johns River from the plant location. This system would utilize a series of settling tanks and a shell-filter lagoon as the principal wastewater treatment. DER, following evaluation, gave notice in October 1984 of its intent to issue permits related to dredge and fill and the construction of the wastewater treatment facility. In the face of that notification, the present Petitioners offered a timely challenge to the issuance of any DER permits. In considering treatment alternatives, Homer Smith had employed various consultants and discovered that treatment beyond coarse screening had not been attempted in processing calico scallop wastewater. Those consultants were of the opinion that conventional treatment methods such as clarification, sand filtration, vortex separation, breakpoint chlorination, polymers and spray irrigation were of limited viability due to the inability to remove key constituents within the waste stream or based upon certain operational difficulties that they thought would be experienced in attempting those methods of treatment. As envisioned by the April 10, 1984, application for permit, interim treatment of the wastewater was provided by the use of a series of settling tanks and a shell-filter lagoon, within which system adjustments were made to the delivery of wastewater treatment. The April 10, 1984, permit application by Smith did not envision any chemical treatment of the wastewater aside from that which might occur in association with the settling and filtration through the shell-filter lagoon. Following DER's statement of intent to issue a permit for construction of the wastewater treatment facility as described in the April 10, 1984, application by Smith, DER became concerned about the potential toxicity of calico scallop wastewater, based upon its own studies. As a consequence, Smith amended the application for wastewater treatment facility to include use of chemical coagulation and flotation. This amendment occurred in March 1985, and the wastewater treatment process in that application envisioned the use of an electroflotation wastewater system. In view of toxicity problems experienced with the testing related to the use of an electroflotation wastewater treatment system, this treatment alternative was discarded in favor of a dissolved air flotation (DAF) system. This system was pursuant to an amendment to the application effective May 31, 1985. This amendment of May 1985 was in furtherance of the order of the hearing officer setting a deadline for amendments to the application. DER issued an amended intent to grant permits for the DAF unit and the associated pipeline and that action dates from June 28, 1985. The Petitioners oppose the grant of these permits for the DAF unit and pipeline, and under the auspices of their initial petition have made a timely challenge to the grant of a permit for the installation of the DAF wastewater treatment unit and associated pipeline. It is the DAF unit and pipeline that will be considered in substance in the course of this recommended order. On July 6, 1984, Smith sought an easement from the State of Florida, Department of Natural Resources (DNR) for the installation of the pipeline. This was necessary in view of the fact that the pipeline would traverse sovereignty lands which were located beneath Trout Creek, Palmo Cove and the St. Johns River. On December 17, 1984, DNR issued a notice of intent to submit that application to the Board of Trustees of the Internal Improvement Trust Fund with a recommendation of approval. This action was challenged by the Petitioners on January 7, 1985, in a petition for formal hearing challenging the grant of the easement. DOAH Case No. 85-0277 concerns this challenge to grant of an easement. Originally, by action of January 28, 1985, the easement case was consolidated with the present DER permit actions. At the instigation of DNR, the easement case was severed from consideration with the present action. The order of severance was entered on July 31, 1985. The DNR case will be heard on a future date yet to be established. The DNR case was severed because that agency preferred to see test results of treatment efficiencies following the construction of the DAF unit. By contrast, the present DER cases contemplate a decision being reached on the acceptability of the construction of the DAF unit and attendant features, together with the pipeline on the basis of theoretical viability of this entire system. This arrangement would be in phases in which the construction of the upland treatment system would occur within 90 days of the receipt of any construction permit from DER, followed by a second phase within which Smith would construct the pipeline within 60 days of receipt of any other necessary governmental approval, such as the DNR easement approval. Furthermore, DER would wish to see the results of an integrated treatment system involving the upland treatment by the DAF unit and its attendant features and the use of the pipeline and the availability of a mixing zone, that is to say the end of pipe discharge, before deciding on the ultimate question of the grant of an operating permit for the wastewater treatment system. The quandary presented by these arrangements concerns the fact that discharge from the DAF treatment unit would be temporarily introduced into Trout Creek, pending the decision by DNR to grant an easement for the pipeline and the necessary time to install that pipeline. Given the difficult circumstances of these actions, there is raised the question of the propriety of discharging wastewater into Trout Creek pending resolution of the question of whether DNR wishes to grant an easement to place the pipeline over sovereignty submerged lands. This is a perplexing question in view of the fact that DNR requested severance from the present action, thereby promoting further delay in the time between any installation of the upland treatment system and the pipeline. Finally, Trout Creek is an ecosystem which has undergone considerable stress in the past, and it is more susceptible to the influences of pollution than the St. Johns River would be as a point of ultimate discharge from the pipeline. This dilemma is addressed in greater detail in subsequent sections within the recommended order. Petitioner River Systems Preservation, Inc., is a nonprofit organization comprised of approximately seven hundred persons. The focus of the organization is to protect and enhance the environment of northeast Florida. The individual Petitioners, Pinkham E. Pacetti, Robert D. Maley, Ruth M. Whitman and others, are members of the corporation who own property or live near the scallop processing plant of Respondent Smith. In addition, Pacetti owns a marina and recreational fishing camp that is located across Trout Creek from Smith's plant. Pacetti's fish camp dates from 1929. On the occasion of the opportunity for the public to offer their comments about this project, a significant number of persons made presentations at the public hearing on August 29, 1985. Some members of the public favored the project and others were opposed to the grant of any permits. St. Johns County Board of County Commissioners, in the person of Commissioner Sarah Bailey, indicated opposition to the project, together with Bill Basford, President of the Jacksonville City Council. Warren Moody, the vice-chairman of the Jacksonville Waterways Authority spoke in opposition to the project. The Florida Wildlife Federation and the Jacksonville Audubon Society expressed opposition to the project. The officials related the fact of the expenditure of considerable amounts of public tax dollars to improve water quality in the St. Johns River and their concern that those expenditures not be squandered with the advent of some damage to the St. Johns River by allowing the permits in question to be issued. These officials considered the St. Johns River to be a significant resource which they are committed to protecting. The City of Jacksonville, Clay County, Green Cove Springs, the Jacksonville Waterways Authority, the Northeast Florida Regional Planning Council and St. Johns County expressed opposition to the project contemplated by the present permit application, through the adoption of certain resolutions. These broad-based statements of opposition were not spoken to in the course of the hearing by members of any technical staffs to these governmental institutions. Private members of the public, some of whom are affiliated with River Systems Preservation, Inc., expressed concern about water quality violations, harm to fish and other environmental degradations that have been caused by the Homer Smith operation in the past and their belief that these problems will persist if the permits at issue are granted. Those persons who favored the project, in terms of public discussion, primarily centered on the idea that, in the estimation of those witnesses, fairness demanded that Smith be afforded an opportunity to demonstrate that this proposed system of treatment was sound and the quality of the water being discharged from the Homer Smith plant was not as bothersome as had been portrayed by the persons who opposed the grant of environmental permits. Industrial Wastewater Construction Permit Treatment System Description of Homer Smith's Plant and Its Operation. The source of water used for the processing of the scallops at the Homer Smith plant is a well which is located on that property. Homer Smith is allowed to withdraw 300,000 gallons of water per day in accordance with a consumptive use permit that has been issued by the St. Johns River Water Management District. To ensure Smith's compliance with this permit, a metering device is located on the well. Typically, the plant operates an eighteen-hour day, five days a week, using water at a rate of 200 gallons per minute. This would equate to 215,000 gallons per day over an eighteen-hour day. Prior to the imposition of restrictions by the Department of Environmental Regulation through the consent order, this facility had processed as much as 40,000 pounds of scallops each day, for a total of 36,000 gallons each week, at a gross revenue figure of $225,000 per week. Characteristics and Frequency of Effluent Discharge The wastewater generated by the scallop processing that is done at the Homer Smith plant is principally constituted of the well water used to clean the scallops, proteinaceous organic materials, and metals. The metals are introduced into the wastewater stream from the scallop tissue. The wastewater stream also has a certain amount of sand and grit, together with shell fragments. The concentrations of organic materials within the wastewater stream are at high levels. There is also an amount of fecal coliform bacteria and suspended solids. The pollution sources within the wastewater stream include total suspended solids (TSS), biochemical oxygen demand (BOD), nutrients (nitrogen and phosphorus) and the coliform bacteria. In the neighborhood of 30 percent of the BOD in the wastewater is soluble. The balance of the BOD is associated with the suspended solids. With time the organic materials in the wastewater stream will decompose and with the decomposition present certain organic decomposition products, which would include ammonia, amines and sulfides. Heavy metals in the wastewater have been in the scallop tissue and are released with the cleaning of the scallops. These metals include cadmium, copper, zinc, iron, manganese, silver and arsenic. The presence of these metals within the tissues of the scallops are there in view of the fact that the scallops are "filter-feeders" which have taken in these elements or metals that naturally occur in the ocean water. The permit application contemplates an average of five days a week of operation for eighteen hours a day. Notwithstanding the fact that in the past the Homer Smith Seafood operation had processed scallops seven day week, twenty- four hours per day, Smith does not desire to operate more than five and a half days a week in the future. That is perceived to mean five eighteen-hour days and a twelve-hour day on the sixth day. The treatment system contemplated here is for a flow volume of around 200 gallons per minute during normal operation. The system can operate as high as 300 gallons per minute. That latter figure approaches the design capabilities of the treatment system proposed. Wastewater is discharged only when scallops are being processed. There is basically 1:1 ratio between the volume of well water used to process the scallops and the amount of wastewater discharged. Proposed Treatment System and Alternatives As already stated, there is no specific industry standard set forth in the DER rules which would describe technology-based standards for the treatment of calico scallop wastewater. In those instances where the agency is confronted with an industry for which technology-based standards have not been established, DER examines the question of whether that effluent is amenable to biological treatment as contemplated in Rule 17-6.300(1)(n)1., Florida Administrative Code, as an alternative. Biological treatment is a treatment form normally associated with domestic waste and the imposition of this treatment technique is in furtherance of achieving a secondary treatment standard found in Chapter 17-6, Florida Administrative Code, which results in 20 mg/L of BOD and TSS, or 90 percent removal of those constituents, whichever is the greater performance in removal efficiency. In the absence of specific standards related to the calico scallop industry, and in the face of the interpretation of its rules in which DER calls for an examination of the possibility of biological treatment as an alternative to treatment specifically described for a given industry, it was incumbent upon this Applicant to examine the viability of biological treatment of the scallop wastewater product. The Applicant has considered biological treatment as an alternative and rejected that treatment form, in that Smith's consultants believe the wastewater is not amenable to biological treatment. By contrast, Petitioners' consultants believe that biological treatment should be the principal focus in treating the scallop wastewater and contend that biological treatment is a more viable choice when contrasted with the option chosen by the Applicant. If this waste is not amenable to biological treatment, Rule 17-6.300(1)(n)1., Florida Administrative Code, envisions an acceptable or minimum level of secondary treatment shall be determined on a case-by-case basis. In the instance where biological treatment is not a reasonable choice, the Applicant is expected to achieve treatment results which are comparable to those arrived at in treating domestic waste by the use of biological treatment techniques. On this occasion, DER had not established what they believe to be a comparable degree of treatment for calico scallop waste, assuming the unavailability of biological treatment. The present case is a matter of first impression. As a result, the idea of a comparable degree of treatment shall be defined in this hearing process, assuming the inefficacy of biological treatment. In that event, DER must be assured that the proposed treatment plan has an efficiency that rivals the success which biological treatment promotes with domestic waste, taking into account the quality of the effluent prior to treatment, available technology, other permitting criteria and the ambient conditions where the waste stream is being discharged. In arguing in favor of biological treatment, Petitioners pose the possibility of an integrated system in which primary settling tanks or clarifiers would be used together with a biological treatment step, which is referred to as a trickling filter, followed by final settling by the use of tanks or clarifiers in an effort to achieve BOD concentrations in the range of 200 mg/L to 400 mg/L. In this connection, the dissolved air flotation system is seen in the role of alternative to the initial stage of settling of the constituents within the wastewater stream. It is not regarded as the principal means of treatment of the waste. The trickling filter system as a biological treatment medium involves the use of a bacterial culture for the purpose of consuming the oxygen-demanding constituents, BOD. The trickling filter technique, if a viable choice, has the ability to remove 70 to 75 percent of BOD and TSS. Petitioners suggest further treatment of the waste beyond primary and final settling and trickling filter can be afforded by involving activated sludge, which according to their experts would end up with a biological oxygen demand in the 20 mg/L range. Although the constituents of the Smith plant's waste are of a highly organic nature, and, at first blush a candidate for biological treatment by use of the trickling filter, the problem with this form of treatment has to do with the intermittent flow in the Smith operation. This intermittent flow is caused by the fact that the plant does not operate throughout the year. The plant operations are seasonal, depending on calico scallop harvesting which does not occur on a routine basis. Therefore, the problem is presented of trying to keep the biological treatment system "alive" and operating at levels of efficiency which can be expected to maintain the percentage of removal of BOD and TSS that a healthy system can deliver. The bacteria colonies which are vital to the success of the biological treatment system must be fed on a continuous basis to maintain balance in the population of the colony. This would be a difficult undertaking with the Smith operation, given the interruptions in operations which could lead to the decline in the bacterial population and a poorer quality of treatment once the operations were resumed. This finding takes into account the fact that the colony can survive for a week or two by simply recirculating water over the filter. Obviously, in order to maintain necessary efficiencies within this biological treatment, the bacteria must do more than survive. The further suggestion that has been offered that the bacteria could be sustained for longer periods of time by feeding them seafood waste or dog food are not found to achieve the level of efficiency in the operation that would be necessary in posing biological treatment as an alternative. Again, it is more of an intervening measure designed to assure the survival of bacteria pending the continuation of the operations of the plant, as contrasted with a system which is continual and taking into account the uniformity of the waste product more efficient. Another problem with feeding the bacteria when the plant is not operating is that of disposing of the waste produced when this auxiliary feeding is occurring. Just as importantly, biological treatment is questionable given the long retention times necessary for that process and the build-up of toxic levels or concentrations of ammonia. The Applicant had employed an aerated lagoon in attempting to treat the waste and experienced problems with ammonia build up. Although this system did not call for the degree of treatment of the waste prior to the introduction into the lagoon that is contemplated by the present proposal of the Applicant, it does point to the fact of the problems with ammonia in the biological treatment system. Dr. Grantham, a witness whose testimony was presented by the Petitioner, conceded the difficulty of removing ammonia from the trickling filter. Moreover, the biological treatment system is not especially efficient in removing metals and phosphorus from the wastewater. Alternative treatment would be necessary to gain better efficiency in removals of those constituents. The trickling filter is expected to gain 50 percent metals removal, which is inadequate given the concentrations of heavy metals found in the scallop wastewater. Phosphorus could be removed after treatment by the trickling filter by the use of lime or alum. Assuming optimum conditions in the use of biological treatment after primary and final settling, thereby arriving at a BOD level of 200 mg/L, it would then be necessary to make further treatment by the use of activated sludge to see 20 mg/L BOD. The problem with activated sludge is related to the fact that this form of treatment is particularly sensitive to interruptions in flow, which are to be expected in this wastewater treatment setting. On balance, biological treatment does not present a viable choice in treating scallop waste. That leaves for consideration the question of whether the Applicant's proposal would afford a comparable degree of treatment to that expected in the use of biological treatment of domestic waste. The manufacturer of the dissolved air flotation unit or DAF system proposed, known as the Krofta "Supracell," offers another piece of equipment known as the "Sandcell" which in addition to the provision for dissolved air flotation provides sand filtration. The Sandcell might arrive at BOD levels of 400 mg/L. However, the testimony of the witness Lawrence K. Wang, who is intimately familiar with the Krofta products, in responding to questions about the use of the Sandcell system and suggestion that the system would arrive at 400 mg/L BOD responded "could be." This answer does not verify improvement through the contribution of sand filtration. For that reason inclusion of a Sandcell for filtration of BOD is not suggested in this fact finding and the system as proposed must be sufficient in its own right. Having realized the need to provide greater treatment than screening or filtering the waste stream, the Applicant attempted to design a treatment system using flotation technology together with chemical precipitation and coagulation. At first the Applicant examined the possibility of the use of electroflotation (EF). This involved the collection of wastewater in a retention tank and the generation of an electric current to create a series of bubbles to float insoluble flocs. Those flocs are caused by the use of ferric chloride, sodium hydroxide and various polymers which are added to the waste stream. The flocs are then pushed to the top of the chamber by the air bubbles, and this particulate matter is skimmed off by the use of a paddle. Pilot testing was done of the electroflotation technology and showed promising results, so promising that a full-scale electroflotation unit was installed and tested. The full-scale electroflotation showed reasonable removal of BOD, TSS, nutrients, coliform and trace metals. This technique was discarded, however, when bioassay testing of the treated effluent was not successful. In examining the explanation for the failure, the experts of the Applicant were of the opinion that certain chemical reactions were occurring as a result of the passage of the electrical current through the wastewater stream. When this problem with acute toxicity could not be overcome through a series of adjustments to the process, the Applicant decided to test another form of flotation, which is referred to as dissolved air flotation (DAF). This system employs the use of chemicals to create insoluble flocs. Unlike the electroflotation unit, though, it does not utilize electrical currents to create the air bubbles employed in the flotation. The dissolved air flotation thereby avoids problems of toxicity which might be attributed to the passage of electrical current through the water column. The present system as proposed by the Applicant has a number of components. The first component of treatment involves the passage of raw wastewater through a mechanical screening device, which is designed to remove a certain number of particulates by catching those materials on the screen. That material is then removed from the plant and disposed of off site. The balance of the wastewater after this first stage of treatment passes into a sump area and from there into a primary mix/ aeration tank. This water is then chemically treated to facilitate the formation of insoluble flocs. The chemically treated wastewater then enters a premanufactured Krofta Supracell 15 DAF unit which is designed to form bubbles by the use of pressurized air, with those bubbles floating the waste materials within the floc to the surface. Again, this method does not use electrolysis. The floated solid materials are then skimmed from the surface and directed to a holding tank and subsequently pumped to sludge drying beds. Some of the treated wastewater is recycled through the DAF unit after pressurization and in furtherance of forming the necessary bubbles for the DAF unit. The balance of the water is directed to a force main lift station. This water would then be transported through the eight-inch PVC pipe some 13,000 feet into the main channel of the St. Johns River where it is distributed through a five port diffuser. The screening mechanism spoken of had been installed in mid-December 1984 and has been used since that time to filter the wastewater. The screening mechanism is in substitution of settling tanks and shell pits. The shell pits which had been used before presented problems with odors as well as the ammonia build up which has been addressed in a prior paragraph. The removal efficiency of the screening mechanism is 30 percent of particulates associated with pollution parameters, as example BOD, total Kjeldahl nitrogen, total phosphorus and TSS. The frequency of the transport of these screened materials to the off site disposal is four to six times a day and the screen is decontaminated at the end of each day when the operations are closed. The application contemplates the same operating procedures of disposal and maintenance with the advent of any construction permit. The primary mix/aeration tank aerates the wastewater and through that process and the retention time contemplated, equalizes the flow regime and promotes a more balanced concentration of waste materials prior to the introduction of that wastewater for chemical coagulation and flotation. This step in the treatment process enhances the treatment efficiency. Some question was raised by the Petitioners on the size of the primary mix-aeration tank as to whether that tank was sufficient to equalize the flow, and conversely, the impacts of having too much retention time built into that tank, which would promote the build-up of toxic concentrations of ammonia in the wastewater. The retention time within the sump and the primary mix-aeration tank approximates one and one-half hours. The retention time and size of the primary mix-aeration tank are found to be acceptable. This design appropriately addresses concerns about the build-up of decomposition products and toxicity, to include ammonia. The sludge which collects in the primary mix-aeration tank will be pumped back to the sump pit by return flow. The sump pit itself will be pumped out in the fashion of cleaning a septic tank on the basis of once a week. The sump pit also receives the return flow of leachate from the sludge drying bed. Once equalization of flow is achieved in the primary mix-aeration tank, that wastewater is then treated by the use of alum, sodium aluminate and polymers. The purpose of this treatment is to convert soluble and insoluble organic matter such as TSS and BOD, trace elements and phosphorus into insoluble flocs that can be removed by flotation. These combinations of chemicals and dosage rates have been tested in electroflotation and dissolved air flotation bench and pilot scales for use associated with this project and a list of appropriate chemicals and ranges of dosage rates has been determined. It will be necessary for these chemicals and general dosages to be adjusted in the full- scale operation under terms of the construction permit. This facet of the treatment process must be closely monitored. Once the wastewater stream has received the chemical treatment, it is introduced into the Krofta Supracell 15 DAF unit. This unit is 15 feet in diameter, and within this cylinder bubbles are generated by pressurizing some of the chemically treated wastewater and potentially clean tap water. The use of clean tap water promotes dilution of the wastewater stream as well as greater efficiency in the production of the bubbles. Chemically treated wastewater is brought into the cylinder through the back of a revolving arm that moves around a center column of the DAF unit at the speed of the effluent flow. The purpose of this mechanical arrangement is to eliminate horizontal water velocity, to protect the integrity of the flocs that are being formed by the use of the chemicals. Those flocs float to the surface in a few minutes' time, given the normal turbulence and shallow depth of the DAF unit. This limited retention time also avoids ammonia build up. The floating material is then scooped and poured into a stationary center section and is discharged by gravity to the sludge holding tank. Wiper blades which are attached to the revolving arm scrape the bottom and sides of the tank and discharge any settled sludge to a built-in sump in the DAF unit. These materials which are settled in the bottom of the DAF cylinder are transported through the sludge holding tank and eventually placed in the sludge drying beds. The treated wastewater is removed by an extraction pipe associated with the center section of the DAF unit. It is then discharged. The use of clean tap water from the well and the ability to recycle the waste stream can promote greater treatment efficiency in terms of removal of undesirable constituents of the waste stream and the reduction of concentrations of those materials. As a measurement, approximately 8 percent of the wastewater flow will be removed as sludge. This sludge is sufficiently aerated to be reduced in volume by about one-half over a period of ten to thirty minutes in the sludge holding tank. It is then sent to the sludge drying beds. The sludge drying beds are designed to accommodate 30,000 gallons of sludge. They are 60 feet long, 25 feet wide and 4 feet deep. Those drying beds are of greater size than is necessary to accommodate the volume of sludge. The sludge drying beds have a sand and gravel bottom. The water drains from the sludge as leachate and returns to the sump pit in the treatment system at a rate of five to ten gallons a minute. Some concern has been expressed that the "gelatinous" nature of the sludge will make it very difficult to dewater or dry. This opinion is held by experts of the Petitioners, notwithstanding the fact that polymers are used in the treatment process. One expert in particular did not believe that the sludge would adequately dry. Having Considered the evidence, the opinion that the sludge will not dry sufficiently is rejected. Nonetheless, it is incumbent upon the Applicant to monitor drying conditions of the sludge very carefully and, if need be, to add some chemical such as calcium hydroxide to enhance the drying capacity of the sludge material. It is anticipated that the sludge will be removed once a day and this arrangement should be adhered to. With adequate drying, the sludge material can be removed with the use of shovels, rakes and a front-end loader as proposed by the Applicant. With frequent removal and adequate drying, problems with odors can be overcome, and problems with ammonia build up and the generation of unreasonable levels of bacteria can be avoided. Should problems with odors, ammonia and bacteria occur, it would be necessary for the Applicant to purge the drying beds, to include the sand and gravel which had been invested with the sludge materials that had caused the problems. Although Smith has not tested the drying bed leachate as to specific nature, the treatment process can be expected to deal with problems of any build-up of ammonia concentrations, fecal coliform bacteria and other organic decomposition products. This pertains to the ability to remove these offending substances from the site in terms of removal of the residual solids and the ability to treat those parameters within the leachate as the wastewater is cycled through the system. The treated wastewater will be transported to a pumping station by gravity flow and then pumped via the pipeline to the proposed point of discharge in the main channel of the St. Johns River. This pipeline is constituted of fabricated sections of pipe 20 feet in length, connected with bell and spigot joints, rubber gaskets and solvent welding. The treated wastewater is released into the river through a five point diffuser which has three-quarter inch openings angled at ten degrees from the horizontal bottom. The pipeline is anchored with prefilled 80-pound concrete bags attached with polypropelene straps which are placed at 8-foot intervals. These are placed to keep the pipe from floating. The diffuser is supported by four piles driven into the river bottom and surrounded by a series of concrete bags. The purpose of this arrangement is to hold the diffuser in place and to protect it against potential damage from anchors or other possible impact. The Applicant acquiesces in the choice to have the pipeline tested for leaks once a month in the period June through September and every other month during other parts of the year. If leaks are found, the Applicant would be responsible for repairing those leaks. As stated before, it is necessary for the Applicant to receive permission from the State of Florida to be granted an easement before the pipe can be installed. Prior to that permission being granted, the treated wastewater would be placed in Trout Creek, which is adjacent to the processing plant. Predicted End of Pipeline Quality of the Effluent In trying to predict the quality of effluent at the end of the pipeline, bench scale and pilot scale testing was done related to the DAF technology. This testing was done related to screened wastewater that was collected from the plant in April 1985. In this connection two series of DAF bench scale tests were performed. They related to samples collected on April 18 and 19, 1985, which were packed in ice and shipped directly to a research laboratory in Lenox, Massachusetts, where they were treated with chemicals and a laboratory size DAF unit. The concentration of the wastewater parameters were measured and recorded before and after treatment, and the results of those tests are set forth in the Applicant's Exhibit A-4(B)(3), at Table 2-1. The pilot scale testing that was done in this case related to a 4-foot diameter DAF unit which had been installed at the Homer Smith plant. This testing occurred in April 1985. The basis of the testing was samples taken on April 15 and 19, 1985. Again, wastewater parameters were measured before and after treatment and the results are set forth in Applicant's Exhibit A-4(B)(3), at Table 2-1. When the initial testing was done with the DAF, results for total coliform bacteria uniformly fell below a range of 35 organisms/100 ml. Subsequent pilot tests yielded higher bacterial counts which would indicate that there was a build-up of bacteria within the DAF unit. This verifies the need to require that the DAF unit contemplated by the application be routinely cleaned or sanitized to avoid the build-up problem. TSS in the pilot unit effluent was reduced to 40 mg/L and lower. The capacity for metals removal in the pilot scale testing was good pertaining to copper and zinc. The ability to remove cadmium showed a result of 0.013 and 0.015 mg/L. The best performance in the pilot scale testing related to BOD removal showed a value of 510 mg/L. It should be noted that the bench scale testing and pilot scale testing were in the face of significant variations in the amount of BOD presented by the screened wastewater. This identifies the need to pay close attention to the removal efficiency of the system related to the BOD parameter in order to achieve consistent levels of BOD following treatment. The system under review is referred to as full-scale treatment. This treatment can be expected to exceed the levels achieved in the DAF bench and pilot scale testing because: (a) As a general proposition, treatment efficiency improves as the scale of machinery increases from bench to pilot to full-scale; (b) The bench and pilot scale tests were run without the benefit of the primary mix-aeration tank and the benefits derived from that part of the treatment apparatus, that is to say, uniformity of the flow and better dispersion of the constituents of the wastewater stream, prior to chemical treatment; (c) The pilot DAF unit used exclusively recycled wastewater to undergo pressurization for the creation of the air bubbles. In the course of the hearing it was established that approximately 50 gallons per minute of clean tap water could be brought in to the treatment process resulting in the formation of more bubbles and the facilitation of up to 10 percent greater treatment efficiency based upon that change. The other contribution made by the use of clean tap water was the possibility of as much as a 20 percent dilution of the wastewater stream, in terms of concentration of constituents within the wastewater stream; (d) In a full-scale operation, the opportunity is presented to routinely adjust the chemical dosages as well as select among a range of chemicals in order to achieve the greatest treatment efficiency; (e) In employing routine sanitization of the DAF unit by use of a mild chlorine compound, the tendency to accumulate coliform bacteria can be overcome. Removal of this adverse influence improves the water quality. In traveling through the pipeline, the transit time is in the range of two to three hours. At a normal rate of 250 gallons per minute of discharge, the transit time in the pipeline is 2.25 hours. Given the constituents of the wastewater, bacterial populations can be expected and could conceivably consume sufficient amounts of oxygen to affect the dissolved oxygen levels within the wastewater as it exits the pipe at the diffuser ports. In addition, there is some possibility of ammonia build up within the pipeline. To avoid the build up of bacteria at harmful levels, sanitation of the DAF unit must be accomplished. In addition, the pipeline itself should be flushed with clean water at the close of operations each day and treated with small amounts of chlorine to address bacteria which may form within the pipeline. This avoids the increasing concentrations of ammonia and protects against lowered dissolved oxygen concentrations and the possibility of increased levels of toxic substances in the effluent which might be attributable to the proliferation of bacteria and the build-up of ammonia during the transport through the pipeline. Taking into the account the nature of this wastewater and the velocity associated with the transport and the sanitization of the pipeline, sedimentation associated with organic solids or other materials will not present a problem. The pollution parameters associated with the treated effluent at the point of discharge from the pipeline can be expected to meet Class III orders, excepting unionized ammonia, specific conductance, copper, cadmium, pH and zinc. In order to achieve satisfactory compliance with regulatory requirements related to those parameters, the Applicant has requested a two-meter mixing zone. The purpose of that mixing zone would be to afford an opportunity for dispersion and mixing in the ambient water before imposition of water quality standards. The implications of that mixing zone are discussed in a subsequent section to the fact finding within the Recommended Order. In effect use of the mixing zone will promote compliance with standards pertaining to the subject parameters. Petitioners point out the fact that the Applicant has based its assumptions on the results of treatment on the availability of four sets of data which were obtained from DAF effluent--two sets of data coming from the bench tests and two sets of data from the pilot plant. Further, there is an indication of the variation in quality of the effluent from one test to the next and the need to employ different dosage rates of chemicals in the face of those variations. The full-scale system utilizes a number of techniques to gain some uniformity in the quality of the effluent prior to chemical treatment and thereby some uniformity in the amount of chemicals necessary to treat the effluent. This overall system can then be expected to produce treated wastewater that is basically uniform in its constituents. Petitioners point out the limited amount of data in the testing related to BOD. There were, in fact, only two data points: one related to the bench system and one related to the pilot system pertaining to BOD, both of these the product of different chemical dosages for treatment. Again, the system that is at issue in this proceeding can be expected to arrive at a more consistent level of BOD than is depicted in the results pertaining to bench scale and pilot scale testing. In fact, those results were not remarkably disparate in that the bench sale test produced 560 mg/L and the pilot scale test produced 510 mg/L. While the data related to BOD is limited, it still gives sufficient insight as to the probability of successful full-scale treatment and the test data is found to be a reliable indication of success in achieving the goal of 510 mg/L BOD. Contrary to the Petitioners' perceptions, the treatment efficiency is improved with the system that is under review. Petitioners believe that the bench and pilot scale testing not only is unrepresentative of the full-size DAF system, they also believe that the full-size system represents a lesser quality of treatment. In this regard reference is made to features which would adversely affect the treatment efficiencies. The first of those pertains to leachate which drains from beneath the sludge drying beds and is recirculated to the existing sump pit and added to the waste stream. Sludge which sits in the drying bed does decompose and causes biochemical reactions to occur, as Petitioners suggest. Moreover, no specific testing has been done of the leachate to ascertain the ammonia concentrations, pH or other chemical characteristics. Nonetheless, given the intention to clean out the residual matter within the sump pit frequently, and the flexibility to make that cleanup more routinely, and the fact that this amount of leachate is comparatively small in its ratio to wastewater which is being sent through the system for treatment, the leachate is not found to be an unmanageable problem. Nor is the sludge a problem. Likewise, the amounts of heavy metals within the leachate can be accommodated. Concerns expressed by the Petitioners related to the organic materials in the primary mix-aeration tank that is being returned to the sump pit can also be dealt with by the evacuation of the materials in the bottom of the sump pit. This can be achieved more frequently than on a weekly basis if that becomes necessary, and in doing so avoid problems with concentrations of ammonia, bacteria, amines, sulfides and general organic decomposition products. These materials which are returned to the treatment process as wastewater reintroduced into the primary mix-aeration tank can be adequately addressed in the subsequent treatment that occurs by reaeration, the use of the chemicals and DAF flotation. The retention inherent in the sump pit, primary mix-aeration tank and sludge drying bed has a potential to cause problems with ammonia build-up; however, the problems can be satisfactorily addressed, as well as potential problems with other toxic substances in the effluent, by routinely taking the residual material in the sump pit and sludge drying bed out of the treatment system. While the specific chemicals and precise dosage rates to be used with a full-size DAF system remain open, the basic concept of chemical treatment has been identified sufficiently. The precaution that is necessary is to make certain that close monitoring is made of the results of changes in the chemicals and dosage rates. Likewise, special attention should be paid to the implications of adjustments in the pH of the effluent to make certain that compliance is achieved with the Class III water criterion related to changes in pH above background. Adjustments can be made without violating Class III water standards related to pH. In testing that was done pertaining to the electroflotation effluent, a number of other chemicals were observed, to include trimethylamine, dimethyl sulfide, chloroform and other hydrocarbons. There is some indication of the presence of dichleoroethane, ethylbenezene and other aromatics. The possibility exists that these substances may also be products within the DAF effluent. In that event, the critical question would be whether they have any adverse effect in the sense of influences on the ability of the effluent to pass bioassays and the ability of the effluent to comply with standards related to other parameters such as dissolved oxygen, BOD, and TSS. The routine testing which is called for by the draft permit, which is deemed to be appropriate, would create a satisfactory impression of the materials set forth in the paragraph in the sense of the implications of their presence and allow any necessary adjustments in treatment. While the effluent produced in the testing on the part of the Applicant is different, it is representative, and the treated effluent which will be produced in the full-scale system will be of a better quality and present less adverse impacts than shown in the past testing. Petitioners question whether the Applicant has given a conservative portrayal in analyzing the effluent. In particular, it is urged that the Applicant claimed to be vying for use of the bench scale testing as a conservative depiction of the results of treatment. In this connection, the impression given in the hearing was that of ascendancy in treatment efficiency beyond the use of bench scale, pilot scale and ending in full-scale treatment. As pointed out by Petitioners, in making his case the Applicant has used results of bench and pilot scale testing. As example, use was made of the results of testing in the pilot scale in describing the removal effioiencies related to cadmium, whereas in the measurements of nitrogen concentrations the bench scale result was better than that of the pilot testing and was utilized. The real question is whether the overall testing has given some reasonable indication of success in full-scale treatment. To that end, use of results from either the bench scale or pilot scale testing is appropriate, and those results point to success in the full-scale operation. The system that is proposed is designed to address fluctuations in flow and concentrations in the effluent, given the primary mix-aeration tank contribution and the ability to recycle flow within the DAF unit, with the use of clean tap water. This will allow the Applicant to deal with the remarkable differences in BOD that were seen in the test period, ranging from 900 to 3000 mg/L. COD data as well as BOD data is limited but is found to be an ample depiction of potential treatment efficiencies related to that former parameter. In addition to the aforementioned references to changes in chemicals in the treatment process, Petitioners characterize the use of clean tap water in the recycle flow as being "unsubstantiated speculation." While the use of tap water was discussed in a theoretical vein, that discussion is found to be an accurate assessment of the value of the contribution of clean tap water to the treatment system. Impacts on St. Johns River Ambient Water Quality and Conditions The St. Johns River and the area of the proposed discharge is a riverine estuary. It has a freshwater source flowing from the south and a tidal ocean boundary to the north. The confluence of freshwater flow and tidal influences causes the water movement within this area to be oscillatory. That is to say that at different times the water will flow downstream, to the north, and upstream, to the south. There are occasions in which the net flow over a given tidal cycle will be zero; however, the water is always moving. Conductivity and chloride data indicate that the freshwater flow is the dominant flow compared to tidal influences. The extrapolation of available flow data indicates that there is a net downstream flow of fresh water averaging approximately 6,000 CFS. The St. Johns River at the point of discharge is over one and a half miles wide and relatively shallow with maximum depth in the range of 3 to 3.5 meters. Given the fact of the width and depth in this segment of the river, and the imposition of wind conditions and tidal influence, the water is well mixed and flushed. There is no stratification in this portion of the river. The Applicant looked into the question of current bearing and velocity in depths between two to fourteen feet in the water column. Eleven sampling stations were utilized in arriving at information about current bearing. This observation was over an eleven-nautical-mile stretch of the main channel of the St. Johns River. These stations are depicted on Applicant's Exhibit 38. In this portion of the river the current at all measured depth was flowing up and down the main channel. Within these sections there is no indication of a pronounced subsurface water movement toward the east and west banks of the river. Current velocities within the three stations closest to the POD averaged in the range of 0.5 feet per second and velocities in the other stations found within the main channel were within that range of movement. By contrast current velocities within the embayment areas along the east bank of the river were substantially weaker. DER conducted two studies using tracing dyes poured into the St. Johns River at the approximate point of discharge and monitored the course of dispersement of that dye. During this observation the dye was constantly replenished while being carried on the currents. While the dye remained within the area of the main channel, it stayed on the east side of the river as it moved down river on the outgoing tide in the direction of Smith's Point and the Shands Bridge. As the tide was slowing before the change of tide, the dye drifted for approximately two hours in the immediate vicinity of the point of discharge. The DER dye study was a fairly gross measurement of the direction of water movement within the river beyond the point of discharge. It tended to confirm that the water flow was basically up and down river, depending on whether the tide is incoming or outgoing. The studies were not sufficiently refined to speak with any certainty on the possibility that some part of the flow regime would move toward the east or west bank of the river. Nonetheless, in examining the nature of the shallow embayment areas along the banks of the St. Johns River, they are not seen to be subject to the basic flow regime that is occurring in the main channel during tide events. The bathymetry in this area is such that if the main flow regime was having some influence on the embayment areas, the depths within those embayments would be more similar to the depths found in the main channel of the river. Petitioners have employed a number of dye and drogue measurements to try to give a more accurate depiction of the influence of flow within the main channel upon the dispersion of effluent upon discharge and the possibility of those pollutants reaching the embayment areas. While there is no dispute over the fact that Trout Creek is a tributary to the St. Johns River with some tidal influences being shown in that Creek and there is no dispute that water from the St. Johns River flows in and out of Palmo Cove and Trout Creek, there does not appear to be a significant flow of water from the St. John River into the cove and creek from the main channel, in particular from the area of the point of discharge. One of the witnesses of the Petitioners, Sandy Young, did a dye procedure in which a plume was allowed to develop over a distance of approximately 1,000 feet. Although some slight lateral variation was shown in the dye plume, it did not identify a basic flow pattern toward the embayment areas on the east side of the river. The DER dye study was over a distance of some eight thousand feet and also showed some minor lateral variation. Both of these dye studies tend to show a basic flow pattern within the main channel. The dye study run by the Petitioners' witness White gave the same basic depiction as seen in the studies by DER and Young and did not identify a flow pattern out of the main channel toward the embayment areas. In the drogue studies run by Young three Chlorox bottles were filled to 95 percent of volume with water and released at the point of discharge. They were followed for a period of five hours. They moved initially with the outgoing tide toward Jack Wright Island and then when the tide slowed, the drogues slowed. When the tide changed with the incoming tide, the drogues moved toward the center of Palmo Cove. The drogue studies by Young do tend to indicate that some water was exchanged from the main channel at the point of discharge and the embayment areas. It is not a very exact measurement as it only deals with the surface area of the water column, given the wind and wave conditions existing on that occasion. It is in no way representative of the flow direction of the rest of the water column. Therefore, although it may tend to identify that some of the pollutants leaving the point of discharge may find their way to Palmo Cove, it does not establish that quantity of that pollution dispersion and the significance of that dispersion. Based upon this evidence it cannot be seen to be so revealing that the assumptions made by the applicant in trying to identify the dispersion characteristics of the effluent at point of discharge are negated based upon the results of the drogue study. The drogue study which Young did and the observation of the movement from Smith's Point to Little Florence Cove are no more compelling than the dye studies done at the point of discharge. When the Petitioners suggest that there is some influence by centrifugal force pushing the water to the outside of the curve toward the eastern bank, they are correct. However, the contention by the Petitioners that the incoming and outgoing tides sweep to the eastern shoreline of the St. Johns River moving toward Pacetti Point, Palmo Cove, Florence Cove and Smith Point is not accepted. Again, the general flow regime is up and down the main channel of the river and not primarily to the eastern bank. Finally, the fact that the Tetratech data produced for the benefit of the Applicant showing the flow pattern within the overall water column, which indicated that the general direction is the same at the top or bottom of the water column, did not tend to identify the fact that pollutants throughout the water column will be dispersed into the embayment areas from the point of discharge. The data collected in the main channel seem to establish that the water was flowing up and down the channel at depths below the surface. The question becomes whether the amount of pollutants that are being brought into the embayment areas is in such concentrations that they tend to cause problems along the shoreline, especially as it pertains to dissolved oxygen levels. From the facts presented, this outcome is not expected. Levels of dissolved oxygen in the St. Johns River can vary in the natural condition as much as 2 to 3 mg daily. These variations are influenced by algal activity and are not uncommon in Florida waters. Dissolved oxygen is essential to aquatic life. Optimum levels of dissolved oxygen for the fish population of the river are in the neighborhood of 6 to 8 mg/L. DER has established a minimum DO standard of 5 mg/L for Class III waters such as Trout Creek, Palmo Cove and the St. Johns River. This standard is designed to achieve uniform compliance throughout water column at whatever time the measurement may be made. DER, by the employment of this rule, is attempting to deal with those instances in which, in view of the dissolved oxygen level, aquatic organisms are placed under greater stress. The lowest DO concentration expected is normally seen in the summer in July, August and September. DO concentrations in the water column are expected to be highest at the surface area and lowest near the bottom. Measurements near the bottom are significant in this instance because the discharge will occur approximately one foot off the bottom of the river. The Applicant took DO measurements of the area in question during the spring of 1984 over a period of three days. These measurements were taken at a time when a better quality of dissolved oxygen might be expected as contrasted with circumstances in the summer. With the amount of wind involved impressive levels of reaeration were also occurring. These measurements showed that in all stations DO levels were at least 5.0 mg/L at all depths. A study by Applicant's consultant Environmental Science Engineering related to a diurnal event for dissolved oxygen was taken approximately one kilometer downstream from the point of discharge in August 1985 and did not reveal any measurements below 5.0 mg/L. The river was choppy on that day and this would improve the quality of dissolved oxygen. Historical data by DER related to water quality at Picolata, which is south of the POD in the St. Johns River, reveals average DO levels of approximately 6 mg/L. Historical water quality data collected by the Florida Game and Freshwater Fish Commission near Green Cove Springs, which is several kilometers north of the point of discharge, indicated average DO levels in compliance with water quality standards. Diurnal data from near Green Cove Springs did not show any history of DO values below the state standards. There is other historical data, however, which indicates that DO concentrations in the general vicinity of the point of discharge do go below 5.0 mg/L. Game and Freshwater Fish Commission data indicate that the readings below 5.0 mg/L could occur as much as 10 percent of the time. This relates to the study done at Green Cove Springs. There does not appear to be any particular pattern to these events of low DO violations other than the expectation of their occurring in the summer months, occurring more frequently in the lower depths of the water column and in areas which are shallow with limited flow. The summer circumstance is one in which there is a possibility of very heavy rainfall followed by hot weather with overcast skies and no wind, and the DO values go down in that set of conditions. The DO values are, in addition to being lower near the bottom of the water column, likely to be lowest in the evening or early morning hours and persist in length of time from eight to ten hours. Some of the Florida Game and Freshwater Fish Commission data from Green Cove Springs depicted some DO concentrations as low as 1.8 mg/L at the bottom and 2.1 mg/L at the surface. The low readings that were taken at Green Cove Springs occurred in September 1979 after Hurricane David had created unusual conditions in the upper St. Johns River as to effects on DO. The same report indicated DO concentrations at eleven stations in the lower St. Johns River in July and September 1982 were in the range to 4.0 to 4.5 mg/L respectively. This particular data is not particularly valuable in view of the location of those stations. There are occasions when the DO concentration at the point of discharge could go below 5 mg/L and could be as low as 2 mg/L on the bottom, but this is not a routine occurrence and would not persist. The Petitioners' consultant Young had taken certain dissolved oxygen readings at the point of discharge in April 1985 and found compliance with the 5 mg/L standard. At other times he and the consultant white measured substandard dissolved oxygen concentrations at the point of discharge. On July 20, 1985, white collected water samples at the surface and at two feet above the bottom and determined that the readings were 4 mg at the surface and 3 mg near the bottom. On August 10, 1985, Young measured DO concentrations of 4 mg/L near the bottom. On August 30, 1985, Young measured DO values of 4 mg/L at the point of discharge. Young had also measured DO concentrations at Green Cove Springs on August 10, 1985, and discovered readings as low as .5 mg/L and ranging up to 3.8 mg/L. A downstream measurement away from the point of discharge in the main channel made on August 10, 1985, by Young showed a dissolved oxygen reading of 4 mg/L. In these August measurements Young had discovered a number of readings that were in compliance with the 5 mg/L requirement. Again on September 5, 1985, Young made a measurement of dissolved oxygen near the bottom of the water column at the point of discharge which was 5.3 mg/L. Young's measurements of dissolved oxygen at the surface and in the intermediate depth, typically were above 5 mg/L. Bottom readings taken by Young in the main channel of the river and to some extent in the embayment areas were extracted from the soft detrital materials, the place of intersection of the river bottom and the water column. DO levels in these anoxic materials would tend to give lower dissolved oxygen readings and, to the extent that this anoxic material remains in the test probe while taking measurements toward the surface, would have an influence on the readings, making them appear lower than would be the case if the anoxic sediments were not present in the test device. These effects were not so dramatic as to cause the rejection of the data collected by this witness. Some explanation for lower DO readings at the point of discharge can be attributable to the fact that the anoxic material associated with high benthic oxygen demand on the bottom reduces the dissolved oxygen in the water column. Although Rangia clams were present at the point of discharge and they are capable of living in an environment of low salinity and low DO, they are likewise able to live in higher ranges of DO and their presence cannot be regarded as meaning that the dissolved oxygen levels are consistently below 5 mg/L. Petitioners' consultant White opined that there would be a very frequent violation of DO standards at the point of discharge, approaching 25 percent of the time. Considering the facts on the subject of dissolved oxygen in that area, this opinion is rejected, as is the opinion that DO concentrations will go below DER standards most of the time in July, August, and September. Young believes that a more involved study of worst case conditions would reveal DO violations throughout the column in the center of the river. The data that was presented was ample to demonstrate that violations would not be that widespread. Nor is the opinion of the consultant Parks on the subject of DO violations, to the effect that they will occur on many occasions accepted. In the Palmo Cove area it is not unusual to see some DO readings below the 5 mg/L standards. The E.S.E. group found substandard DO conditions in Palmo Cove at sampling Station 1 in September and October 1984 and some instances in April and May 1985. DO concentrations were found in the range of .4 and .6 mg/L in August 15 and 30, 1984, respectively, with DO concentrations of 1.8 and 2.1 mg/L reported on October 4 and October 29, 1984, respectively. DO violations in four out of eight checking periods between April 25 and May 24, 1985, were shown in the Palmo Cove area. Measurements taken by the consultant white showed 3 mg/L at the surface and 2 mg/L at the bottom on July 28, 1985. The consultant Young also made a measurement of 3.2 mg/L of dissolved oxygen on August 10, 1985, in a mid-depth reading in the Palmo Cove area. On September 5, 1985, he found a DO reading of 4.0 mg/L. At those places along the eastern shoreline of the St. Johns River and the relative vicinity of Florence Cove, Jack Wright Island, Little Florence Cove and Colee Cove, low dissolved oxygen readings were found, that is below 5 mg/L. These coves can be expected to have substandard readings frequently during the summer period, based upon measurements taken by the consultant Young. In the conduct of the drogue study related to the Chlorox bottle, the consultant Young in tracking the path of those bottles, found a couple of locations in the path of the drogue which were in the range 2.8 to 4.2 mg/L and 2.0 to 4.6 mg/L. The influences of the discharge will not reduce DO in the embayments. The ambient conditions for BOD in the area where the discharge is contemplated is relatively low and there is no thermal or saline stratification even in the summer months. Nutrient concentrations in this part of the St. Johns River are as indicated within the Applicants Exhibit A-4(B)(3) and at present are at such levels as to promote a healthy fish community. There is algae production that can be sufficient in some areas within this section to cause algae blooms. Algae blooms are not found to be a routine occurrence. Algae blooms reflect higher levels of nitrogen and phosphorus. The consultants Young and White have seen algae blooms in the St. Johns River away from the general area of concern, both upstream and downstream. Should those algae blooms occur, they would promote significant rises and falls in DO concentrations. In Palmo Cove and the St. Johns River, supersaturated DO concentrations have been detected and they are indications of high rates of primary algal productivity. The circumstance of supersaturated conditions, related to dissolved oxygen, can be the by-product of an algal bloom. The concentrations of nitrogen range from an average of 1.42 to a maximum of 2.54 mg/L. Nitrogen concentrations of 1.4 mg to 1.5 mg/L are optimally advantageous for fish production. Significant increases above those levels would cause the decline of the fish population. Total phosphorus concentrations in the ambient waters are high. Concentrations in excess of 0.1 mg/L of total phosphorus are regarded as a indication of eutrophication and the average concentration here is measured as 0.3 mg/L with a maximum ambient concentration found at 0.52 milligrams per liter. There is significant algal growth in the inshore areas and an indication of some eutrophication in the grass beds. The dominant species of algae found in that vicinity are blue-green, which are seen as being nuisance species. The grass beds along the shoreline are basically healthy. On the other hand, some of the public witnesses identified the fact that grass beds and other vegetation have died with the advent of discharge from the Applicant's plant into Trout Creek. This was under a system in which little or no treatment was afforded the effluent. One other public witness indicated that his dock in the Florence Cove area had been covered with a slimy material and algae during the past two years. Significant grass beds are found along Jack Wright Island and in other areas along the eastern shoreline of the river. These grass beds are important as fish habitat to include nursery areas, areas for various juvenile species of fish and other organisms. Some of these grass beds are showing signs of environmental stress, and nutrient loading can contribute to that stress. Some of the grass beds are covered with higher amounts of algae, duckweed and periphyton than are desirable. The duckweed had floated into these areas from other locations and can be expected to move away. The presence of algae is an indication of nutrient loading. The presence of duckweed is not a product of nutrient loading in the sense of the production of the duckweed at the site where they were found along the shoreline. The area in question between Pacetti Point and Shands Bridge serves as a nursery in a sense of providing habitat for juvenile species of fish and other organisms. The grass beds along the shoreline provide habitat for feeding and breeding related to juvenile organisms, to include such species as bass and shrimp. Juvenile catfish are found within the deeper portions of the river as well as croaker and other marine species. There is a high number of juvenile blue crabs in this area of the river and this is a commercial resource. Shrimp are taken by recreational fisherman in the area of the North Shore Pacetti Point. Clam beds are also present near the point of discharge. Juvenile and adult manatee have been seen in the St. Johns River and in the area near Jack Wright Island. Manatee have also been observed in Trout Creek at a time before the operation of the Applicant's plant and at times following the cessation of operations in June 1985. During the course of the operation of the Applicant's plant, when raw effluent was discharged into Trout Creek, fish kills were observed. Those events had not been seen prior to the operation of the plant. Indications are that fish were killed in the creek due to the use by the Applicant of fly bait, which made its way into the water. Dispersion Modeling of Water Quality Impact In order to gain some impression of the influences caused by the dispersion of the pollutants within the effluent, the Applicant through its expert employed several modeling techniques. DER was made aware of this modeling as it developed. A far-field model was used to calculate what the long-term or steady state impacts of the treated effluent would be on the ambient water quality. In trying to identify the influence of the discharge, measurement of metals were taken based upon an assessment of long term increases. BOD, which breaks down and consumes oxygen over time, was examined in the sense of the long term effects as to DO deficits. In essence these projections were superimposed over the ambient condition to gain an impression of the adjusted ambient values, taking into account the influence of the discharge. The Applicant also ran a plume model which was designed to calculate spreading and dispersion of the treated effluent within the zone of initial dilution or mixing zone at the point of discharge. This model responds to the discharge configuration. Through the use of computer calculations, it was established that a five-point diffuser with port openings of 0.75 inches in diameter angled upward at ten degrees would result in an effluent dilution ratio of 28.5:1 within two meters of the point of discharge. The calculated impacts of the plume model were superimposed upon the adjusted ambient water quality conditions set forth in the far-field model in order to determine net impact upon the receiving waters within the mixing zone. A third model was used, referred to as the lateral diffusivity model. This model is designed to calculate the six-hour or short term water quality impacts of the treated effluent when it moves from the zone of initial dilution during flood and ebb tide conditions. By estimating dispersion rate, this model predicts what dilution would occur in the path of the effluent plume. These impacts were then superimposed upon the adjusted ambient water quality conditions to determine the total impact in the path of the plume. The modeling work by the Applicant's consultant is a reasonable depiction of the predicted impacts of the pollution on the ambient conditions. The calculations used in the far-field model assumed a freshwater flow of 2,000 CFS. This assumption in the far-field model satisfactorily addresses worst case flow conditions related to seven-day, 10-year low flow. The temperature utilized in depicting ambient water was 30 degrees centigrade when employed in the far-field and lateral diffusivity models. This corresponds to warm weather conditions, which are more profound in describing effects on water quality. The far-field and lateral diffusivity models assumed that the treated effluent discharged from the pipeline would have a BOD concentration of 665 mg/L. This is contrasted with the maximum concentration allowed by the draft permit, which is 510 mg/L, which is the expected amount of BOD. This tends to depict the impacts of the discharge more conservatively. The model assumes the BOD loading of 2,720 kg per week, equating to an average discharge concentration of 665 mg/L if the plant operates five days a week on an eighteen-hour day. The reaeration rate and NBOD and CBOD decay rates used in the far field and lateral diffusivity models are acceptable. Likewise, the longitudinal dispersion coefficient that was used in the far-field model is acceptable. The standard modeling methodology in this process calls for an assumption of a 1.33 growth rate of the plume in the lateral diffusivity model. The Applicant's consultant decided to use a lower constant diffusivity growth rate. As a consequence, less lateral spreading is depicted. With less lateral spreading, less dilution is shown, and the impacts predicted by the model are exaggerated. One of the parameters of the plume model has to do with river flow which causes some turbulence and also brings about dilution. In this instance the plume model calculations assume stagnant conditions which is a more conservative assessment. As the Petitioners have suggested, the modeling to explain the impacts of dispersion of the pollutants is not designed to give precise calculations of the DO deficit at each point in the river along the eastern shoreline. It is indeed an estimate. The estimate on this occasion is reasonable. Although DER performs mathematical analysis of dispersion of proposed discharge in some cases, it did not do so on this occasion. Nonetheless DER was satisfied with the present choice for modeling the dispersion characteristics of the discharge. Although the models utilized were not subject to exact calibration by measurement of the dispersion at the site, the information gained by the Applicant prior to the imposition of the modeling techniques was sufficient to develop the models and to give a theoretical verification of the expected impacts from the discharge. The Applicant's belief that the maximum DO deficit caused by the discharge will not exceed 0.1 mg/L is accepted. The dissolved oxygen level in the effluent at the point of discharge will be above 5 mg/L. The Applicant's choice of reaeration rates, CBOD decay rates, NBOD decay rates, discharge rate from the pipeline, hours of operation, average reversing current speed, net non- tidal flow, non-tidal velocity, time lag before NBOD decay, maximum tidal velocity, and other variables and assumptions within the models were acceptable choices. Although the possibility exists of an occasional 5 1/2 day operation in which 10 additional hours of operation are added, this would not be so significant as to set aside the predictions as to the pollutant dispersion. The Applicant's consultant who modeled the dispersion rates did not conduct dye studies to verify or calibrate the actual dispersion in the river. One of the dye studies indicated a lateral spreading rate which was less than that predicted by the model. Notwithstanding this revelation, the overall techniques used by the Applicant in predicting lateral spreading rate are sound and do not present a risk of a greater DO deficit than was predicted based upon incorrect assumptions as to lateral spreading rates. The Applicant's consultant's use of 2,000 CFS as the net non-tidal low flow was a more convincing estimate than the field data collected by the United States Geological Service, given the paucity of information about the flow conditions within the St. Johns River. The Applicant's choices in describing maximum tidal velocities and average velocity are accepted. The critique of the modeling efforts done by the Applicant that was made by Petitioners' consultant, Dr. Parks, in which he concludes that the DO deficit is considerably greater than 0.1 mg/L is not accepted. Comparison of Predicted Impacts of Discharge with Statutory and Regulatory Criteria Inside the Mixing Zone Applicant's assumptions about the increase in nutrient concentrations in the St. Johns caused by the discharge are accepted. This is based on the assumption of a nitrogen value of 52 mg/L which was achieved in bench scale testing of the effluent and which can be achieved in the full scale operation. As the effluent is discharged from the diffuser within the mixing zone, there will be some turbidity problems in that the bottom near the point of discharge. The soft silt there is easily resuspended. When the discharge is concluded, the material will settle back to the bottom. There will be further resuspension when the operation commences again and there is a discharge. The transport of these suspended materials is limited in that the water velocity associated with the discharge is quickly dissipated. This phenomenon will not cause adverse environmental impacts. The mixing zone does not include an area approved by the State of Florida, Department of Natural Resources for shellfish harvesting; it does not exceed the presumptive maximum size set forth in Rule 17-4.244, Florida Administrative Code. Nor does it include an existing drinking water supply intake or any other existing supply intake that would be significantly impaired by the proposed mixing zone. The water in this area is of sufficient depth that it will not support grass beds that are associated with a principal nursery area, such as pond weed, midgeon grass, manatee grass, turtle grass or eel grass which are used to support nursery activities. These grasses are normally found inshore. Although juvenile fish are found throughout this reach of the St. Johns River, and for that matter in the entire lower eighty miles of the St. Johns River, the mixing zone is not of such dimensions that it will preempt the health of juvenile fish. Most of the freshwater fish in this system use the littoral areas for reproduction. Marine and estuarine species do not reproduce in the St. Johns River. There is some reproduction that is occurring with some species, such as catfish. Given the size of the mixing zone, no significant adverse effects will occur with the established community of organisms in this portion of the river. The mixing zone will not otherwise impair designated uses of the St. Johns River. The treated effluent will not create a nuisance condition or violate any other DER standards that apply within the mixing zone. With the advent of the full scale facility, maximum, average and chronic toxicity criteria can be reasonably expected to be met at the point of discharge, within the mixing zone and at the boundary of the mixing zone. As described before, the effects of sediment transport upon discharge are localized. The proposal for a mixing zone takes into account Rule 17-4.244, Florida Administrative Code, in the sense of addressing present and future sources of pollutants and the combined effects with other pollutants or substances which may be present in the ambient waters. One of the concerns which DER has about wastewater is the effect which that pollutant has on organisms within the environment. To gain an impression of that influence, testing is required to establish whether the wastewater is acutely toxic. The testing is known as bioassay assessment. While this assessment is normally done after the grant of a construction permit, when confronted with uncertainty about the quality of the effluent, some testing is beneficial prior to the grant of a construction permit. This is especially true given DER's experiences in dealing with raw effluent of several of the scallop processors, to include Homer Smith, which showed that the raw effluent was acutely toxic. This acute toxicity testing is done by placing test organisms into aquaria containing the effluent and measuring survival of those species over time. Results are described in terms of a measurement of the concentration of the effluent at which 50 percent of the organisms are killed during a prescribed test period. In static testing the organisms are simply exposed to the effluent for the requisite period of time. By contrast, a static renewal test calls for the effluent to be replaced with another sample of the effluent at various intervals within the test period. Finally, a flow through bioassay test calls for a continuous stream of fresh effluent to be introduced in prescribed concentrations over the duration of the test. A bioassay assessment in the static condition was performed related to DAF pilot scale effluent that was collected on April 19, 1985. In this instance Daphnia magna were used as test organisms and demonstrated a survival rate of greater than 50 percent in a 100 percent concentration of effluent over a period of 96 hours in the setting of static and static renewal tests. That survival rate was also shown in lesser concentrations of effluent as well. The April 19, 1985, sample was also used in testing the response of Pimephales promelas. These test organisms did not survive either in the static or static renewal tests. While an hypothesis has been made that acute toxicity was experienced in this test organism attributable to build-ups of ammonia, which is greater with this type of organism than with the Daphnia, due to larger biomass which allows for a greater number of ammonia generating bacteria to be presented in the test aquaria and the fact that the Pimethales excrete more ammonia, these differences do not definitely explain why the Daphnia survived and the Pimephales did not. In the series of static renewal bioassays performed on the wastewater that was collected at the plant on April 29, 1985, and shipped to Lenox, Massachusetts, for bench scale treatment, the test organisms of both types failed to survive for 96 hours. It was discovered that during the course of the test period, levels of ammonia rose rapidly. Trace metals in the treated effluent are principally in the form of stable species, as opposed to free ions. These constituents standing alone are not likely to have caused the mortality in the test organisms. The effect of decomposition of the organic constituents in the waste stream is the most likely explanation of why the bioassays of pilot and bench scale treated effluent did not lead to a satisfactory result. Unionized ammonia, a by-product of organic decomposition, is found to be a principle player in the explanation of why the treated effluent was acutely toxic to the test organisms. The exact cause of toxicity has not been precisely identified. Given the complex nature of the effluent, other potentially toxic substances such as sulfides, amines, and other organic compounds could have contributed to the demise of the test organisms. Moreover, toxicity can increase with combinations of chemicals acting in a synergistic fashion, making their combined effects more devastating than the effect of any single substance. Having in mind the fact that ammonia is a major problem in the survival of test organisms subjected to a bioassay, the question becomes one of what may be done to remove ammonia. The production of ammonia in wastewater would depend upon the presence of bacteria. The proposed DAF system removes substantial numbers of bacteria, thereby limiting the possibility of ammonia build-up, if bacteria are not allowed to recolonize in some part of the system prior to discharge. As discussed before, reduction of bacterial activity can be achieved within the proposed treatment system. This is unlike the experience with the bench scale and pilot scale testing that was done on the effluent in which a substantial amount of time transpired before subjecting the test organisms to the effluent and in which a substantial amount of time transpired while the test organisms were being subjected to static and static renewal procedures with the same effluent. The time intervals contributed to the build- up of toxic levels of ammonia in the effluent. The system which is proposed in this instance can avoid the problem of time as it relates to the build-up of levels of ammonia. To further reduce the influence of retention of the waste product, flow through bioassay testing would be the most appropriate measurement of the survivability of the test organism in that it would be responding to real case conditions pertaining to the quality of effluent and its potential toxicity. Under these circumstances, it is reasonable to believe that in a flow through bioassay test of the full scale treatment system, the test organisms could survive. This determination is reached given the reduction in retention time compared to the bench and pilot scale testing, which reduces ammonia, with further ability to reduce ammonia by frequent removal of residual materials from the sludge drying bed and sump pit and taking into account basic improvements in treatment efficiency associated with the full scale system. In addition, the pH of the effluent can be regulated to avoid toxicity in the ammonia which is associated with inappropriate balance within the pH. While a 96-hour LC-50 cannot be calculated with the results of bench scale and pilot scale testing, a reasonable possibility exists for the establishment of that measurement with the advent of a flow through bioassay. There is sufficient similarity between the effluent in the pilot and bench scale testing and the expected effluent in the full-size system for the bioassay testing that was done in those limited systems to give a meaningful indication of the probability that the Applicant can pass a flow through bioassay. Applicant can be reasonably expected to produce an effluent in the mixing zone which will not exceed the 96 hour LC-50 for acute toxicity. As with the circumstance of ammonia, pH can be controlled within the system to address the implications of changes in pH as it pertains to other pollutants in the wastewater. Ammonia production can be influenced by the amount of alkalinity in the effluent and the receiving waters. Alkalinity has not been measured thus far. Alkalinity could be established for the effluent and receiving waters and dealt with if it was suspected as being an explanation of problems with the build up of ammonia which might exceed DER standards. The discharge from the Applicant's plant will not cause long-term problems with low DO, high nutrients, algal imbalances, and chronic toxicity. Outside the Mixing Zone Those constituents within the waste stream, to include those for which a mixing zone was sought, will comply with applicable water quality standards at the boundary of the mixing zone. The dissolved oxygen deficit at its maximum can be expected to be in the neighborhood of 0.1 mg/L and will be exerted somewhere in the range between 1 and 2.5 km downstream of the point of discharge across the width of the plume in worst case conditions. This deficit is not of a dimension which is easily detectable. The implications of that deficit are difficult to perceive in terms of tangible environmental consequences. While a deficit in the range of 0.1 mg/L has some relevance in the DER permitting decision, that deficit as it is dispersed is not expected to cause or contribute to violations of water quality standards in the main channel of the river or in the inshore and embayment areas. While it is true that there are periodic fluctuations of dissolved oxygen below 5 mg/L, DER, as a matter of present policy and professional judgment believes that in this system which evidences characteristics of a clean well-flushed, unstratified water body occasional readings of low DO are not regarded as an indication of violation of water quality standards. This speaks to the main channel area of the river where the only quantifiable influence is expected. The facts presented in this case support the soundness of this policy choice. Petitioners presented the testimony of former officials within DER, namely Parks and Young, who stated that dissolved oxygen standards of 5 mg/L are applied at all times and at all places. They felt that the DER policy was to the effect that permits would not be granted for discharge in any circumstance where the DO concentrations are substandard in the ambient waters, regardless of the amount of decrease or deficit that would be promoted. Parks spoke of the availability of site specific alternative criteria, variances, exceptions or exemptions from the terms of the water quality rule. Having considered these remarks, the present DER policy of allowing the permit to be granted in the instance where occasional violations of ambient water quality standards related to 5 mg/L occur, in the face of the small deficit which is involved in this case, is the better choice. Further, it is a choice that is not so inconsistent with prior practices as to be arbitrary in nature. Finally, DER's position that it would be unadvisable to require a request for site specific alternative criteria, variances, exceptions or exemptions in circumstances such as this case is accepted, when taking into account the problems which would be presented to the agency in administering the permit program, should each Applicant who is confronted with occasional violations below standards for dissolved oxygen have to seek extraordinary relief. While the facts do identify that some pollutants can reach the embayment areas on the eastern shore, the facts do not depict a circumstance in which the amount and quality of that effluent will be such that it will cause or contribute to dissolved oxygen violations in those areas. The water quality in the embayment areas is lower than that in the main area of the river due to inadequate flushing. The areas inshore do not interact with the main channel in a way that would take advantage of the faster moving currents found in the main channel as this interaction might promote a better quality of water. In view of the situation in the embayment areas, the Applicant, on advice of his consultants, moved the proposed location of the discharge into the main channel away from the areas which were under greater stress in terms of dissolved oxygen values and in doing so avoided damage to these areas. The current velocities in the area east of the main channel are weak. There is a substantial distance from the point of discharge to the inshore areas. As the effluent moves toward the inshore or nearshore areas it will become so diluted it will not have an adverse influence on dissolved oxygen. Not only the distances involved, but also the fact that water flowing near the surface is well aerated contributes to the dilution of the effluent as it approaches the shore. Although it has been shown that some stress in the grasses along the eastern shoreline has occurred and the existence of blue-green algae has been shown, together with indications of undesirable algal production, the nutrients which are part of the effluent at the point of discharge are not expected to cause an imbalance in the natural populations of flora and fauna or create nuisance conditions or violations of transparency standards. The nitrogen increase could cause an increase in algal production in the order of one percent, which is inconsequential. The treated effluent will not adversely effect biological integrity of the St. Johns River. The benthic microinvertebrate community in this part of the river is fairly low density due to the fluctuations in salinity levels and predation by fish and blue crabs and given the nature of this substrate which is unstable with low levels of dissolved oxygen. The organisms that are predominant have a tolerance to siltation and fluctuations in dissolved oxygen. The treated effluent will not adversely effect the microinvertebrate community. Petitioners point out the fact that when DO concentrations decrease below optimum levels, fish and other organisms suffer. The fish reduce their movement, feeding and reproduction and they are less disease resistant. They are placed in a position of having to leave the area or risk death if the impacts of the decrease in dissolved oxygen are severe. The influence of the effluent at the point of discharge in this project is not expected to have significant impact on fish and other organisms within these topics of concern expressed in the paragraph. Even though the dissolved oxygen deficit extends in amounts below 0.1 mg/L as far as 2.1 km upstream and 4.5 km downstream and within a wide breadth of the center portion of the river, those deficits will not be significant to the water quality. The BOD associated with the discharge, allowing for mixing will not depress dissolved oxygen levels below DER standards of 5 mg/L. The combination of BOD and nutrient discharge will not cause an imbalance of algal production in the river, nor will it contribute to the dominance of nuisance algal species. The BOD nutrient loading associated with the discharge into the St. Johns will not promote significant ecological impacts on the St. Johns River, to include the possibility of more frequent and severe algae blooms, increase in benthic oxygen demand, risk of increase eutrophication, destruction of grass beds or decline in the fishery. With the advent of discharge in the St. Johns DO fluctuations in the river will not be greater nor will there be an occurrence of a swing from substandard dissolved oxygen levels to supersaturated dissolved oxygen. While the discharge from the Applicant's plant contains pollutants such as cadmium, zinc, arsenic, copper and organic decomposition products, the treatment provided the wastewater is expected to overcome any acute toxicity associated with these materials individually or in combination. Chronic toxicity is not expected related to these materials. The effects of these materials are not expected to cause physiological and behavioral responses which are abnormal in organisms such as reduced locomotion and reproduction or increase susceptibility to diseases to include ulceration and increased mortality. Treatment contemplated and provision of a mixing zone will allow compliance with the standards related to cadmium. Reference has been made to a development known as St. Johns Harbor which is in the vicinity of the proposed discharge and can be expected to promote some pollution in Palmo Cove and the St. Johns River. Although St. Johns Harbor development is proceeding through stages of permit review, it does not appear that it has reached a place in which exact information about its implications as a pollution source can be set out. In discussing the St. Johns Harbor Development, Petitioners emphasized that this eventuality and other matters which deal with cumulative impact have not been satisfactorily addressed. There is no indication than any other substantial development or activity other that St. Johns Harbor is contemplated in this area associated with the permit review at hand. St. Johns Harbor eventually hopes to develop 3000 residential units. It has received the approval of the Northeast Florida Regional Planning Council for the initial phase of development. It has been reviewed by the Florida Fresh Water Game and Fish Commission. The developers are proceeding with the project to include the sale of lots. Nonetheless, that development has not reached the phase where its implications would form the basis of a denial of this project based upon the theory of cumulative impact. While Petitioners contend that stormwater runoff from the St. Johns Harbor project will be a problem, assuming an inadequacy in the design which that developer employs to deal with that matter, this eventuality is not expected based on a review on the facts presented. Reference is made to the Ulcer Disease Syndrome which fish in the St. Johns have suffered from. The principal area in which this event has occurred is north of the area expected to be influenced by this discharge. Nonetheless, diseased fish have been found in Palmo Cove. This Ulcer Disease Syndrome is caused by heavy metals and hydrocarbons, and these materials act in league. The advent of additional heavy metals and other pollutants, such as those being discharged from the Applicant's plant could cause further deterioration in the condition of fish suffering from Ulcer Disease Syndrome. Having considered the facts, this outcome is not expected. Ambient levels of 18 other pertinent pollution constituents in the vicinity of the point of discharge were ascertained by the Applicant's consultants on the basis of field observations and historical United States Geological Survey and Florida Game and Fresh Water Fish Commission data. This formed a basis of an assessment of average and worst case values. This information indicates compliance with those parameters for purposes of water quality standards at the point of discharge. Implementation of Construction Permit Permit Conditions Applicant's Exhibit A-10 is a copy of the DER intent to issue the construction permit. It sets forth seventeen specific permit conditions, and these conditions should be imposed in the permit. The following are additional conditions that should be set forth in the construction permit: The operation and maintenance manual required by original Condition 10 shall provide that the DAF treatment system be cleaned regularly with a mild chlorine solution and that the wastewater from this maintenance be placed in a vehicle and carried off the premises for disposal at an appropriate location. This wastewater from the cleanup shall not be discharged from the plant into state waters. The operation and maintenance manual shall provide that a dosage level of chlorine to clean the pipeline that will result in comp- liance with all water quality standards at the end of the pipeline be added to a fraction of fresh water used to flush the system at the cessation of discharges each day. DER must approve this dosage amount before it becomes part of the operation and maintenance manual. The operation and maintenance manual shall set forth a regular schedule for pumping the accumulated sludge or solid materials from the sump pit. The operation and maintenance manual shall provide that as much as 50 gallons per minute of fresh tapwater may be added to recycled wastewater for pressurization. Any discharge created with this addition may not exceed 250 gallons per minute. Any discharge created above 200 gallons per minute shall be consti- tuted only of tap water. Two machine scallop processing operations at the plant will be limited to an average of 18 hours per day and no more than 90 hours in a week. Monitoring in Trout Creek shall continue as specified in paragraph 17(E) of the Consent Order as long as discharges into Trout Creek continue. On each occasion when the DAF treatment system is in operation, the Applicant shall have a fully trained operator on site. The terms of the construction permit shall expire on December 31, 1986. The constructed pipeline shall be leak tested once a month from June to September and every other month during other months of the year. If a leak in the pipeline is detected it shall be repaired within 20 days and retested for leaks within 15 days thereafter. The carrying out of any leak testing and repairs shall hereunder shall be certified by a professional engineer. Pre-pipeline Operations Petitioners have pointed out the fact that when two or more pollutants are present, as in the instance of the effluent discharged by the Applicant's plant, those pollutants tend to act in a synergistio manner. That can exacerbate the circumstance where you find low dissolved oxygen. This is particularly a matter of concern when discussing Trout Creek. This is unlike the impacts of the discharge into the St. Johns River which are not expected to exceed standards or promote adverse effects. The implications of operation within Trout Creek to allow necessary permit review by DER and the State of Florida, Department of Natural Resources can be overcome once the discharge is withdrawn from Trout Creek and may be addressed by DER more immediately if the dissolved air flotation unit, after a reasonable period of adjustment, does not perform in the fashion that it appears to be capable of. In the instance of discharge into Trout Creek, the material discharged tends to remain in that area for a relatively long period in that the creek is small and has very little flow and poor flushing characteristics. DO levels will be depressed, the presence of a deficit in dissolved oxygen caused by the discharge from the DAF unit would increase the probability of fish kills when contrasted with a circumstance where there is no further deficit of dissolved oxygen. Given the explanation of why a fish kill occurred based upon the past use of fly bait by the Applicant and the fact that there is no indication of fly bait in the present plans, a fish kill in Trout Creek in the time of interim discharged does not seem probable. With the advent of discharge into Trout Creek, the possibility is enhanced for algae blooms and increased eutrophication. There would also be some accumulation of toxic substances. Additionally, there would be some influence on juvenile fish which are more sensitive to pollutants and the possibility exists that it could reach levels that are lethal to bass larvae and juvenile sports fish. The creek would lose some of its viability as a nursery and some fish would leave the creek. These events are not irreversible and can be reasonably remedied with the cessation of discharge into the creek. Moreover, as in the instance with the problem with fish kills, if some set of circumstances attributable to the discharge were to occur in such dimensions as to cause long term impacts in Trout Creek, DER could take action against the construction permit. Dissolved oxygen in Trout Creek can be below the 5 mg/L standard. Data of the E.S.E. group showed that at Highway 13 bridge, approximately fifty yards from the plant in December 1984 and January 1985, values were as low as 0.1 and 0.2 mg/L, and readings could be frequently below 2 mg/L at Highway 13. In April through June 1985, periodic surface dissolved oxygen concentrations were in the range of 3 mg/L and as low as 2.4 mg/L. DO concentrations generally found at the bottom of Trout Creek could be as little or lower than 1 mg/L at times. In July 24, 1985, at the time when the plant had not been operating for approximately a month, the DO concentrations were 2.9 mg/L at mid-depth and 0.8 mg at the bottom. Within Trout Creek in the area of the Pacetti marina, Consultant White measured DO concentrations in the range 1-3 mg/L. On August 10, 1985, six weeks after operations had stopped at the Smith facility, DO concentrations were found to be 3 mg at the surface, less at mid-depth and 0 near the bottom. Computer modeling was not done to ascertain the impacts of a discharge directly into Trout Creek from the DAF unit. The modeling done by the Petitioner's consultant, Parks, using some of the concepts considered in the Applicant's modeling for the St. Johns River is inapplicable to the circumstances in Trout Creek. Trout Creek has also served as a nursing ground for reproduction and habitat for young fish. During the course of the operations by the Applicant in the discharge of essentially untreated effluent, the beds of bass and sun fish have not been seen within the creek. Water quality improves with the DAF unit and sediment loading by heavy metals decreases. Trout Creek is a stressed system at present. It has low levels of dissolved oxygen, high nutrient concentrations and the presence of heavy metals in undesirable amounts. The low numbers of pytoplankton species give some indication of a highly stressed ecosystem. The present officials of DER, Palmer, Owen and Fox, expressed their concerns about dissolved oxygen in those instances where there would be a decrease in ambient DO concentrations. This has particular importance in discussing the problems associated with the discharge into Trout Creek, as opposed to the point of discharge contemplated in the St. Johns River, which risk is minimized given the characteristics of that area and the higher readings of ambient dissolved oxygen in that water, as contrasted with low readings within Trout Creek. A literal interpretation of the position of the agency officials would lead to the conclusion suggested by the Petitioners that no discharge should be allowed into Trout Creek, even on an interim basis. However, such a position would be inherently unfair considering the fact that some discharge would occur into the creek before the installation of the pipeline, whether based upon simultaneous permit review by DER and the State of Florida, Department of Natural Resources in the easement case or sequential review as is contemplated in this instance. Admittedly, the amount of time involved in the discharge into Trout Creek increases in view of the severance of the easement case from the present proceedings. This circumstance occurred in view of the desire on the part of the DNR to see the actual treatment efficiencies involved with the dissolved air flotation unit as opposed to the theoretical possibilities of that equipment. In the present situation, it would be a reasonable policy choice for DER to allow an interim discharge into Trout Creek pending the opportunity for DNR to monitor the quality of the effluent produced by the DAF unit and make a decision about the easement, thus allowing installation of the pipeline if the easement is granted. This arrangement contemplates that DER should closely monitor the quality of the effluent produced by the DAF unit, to make certain, after the Applicant has been given the opportunity to make necessary adjustments to that unit, that the Applicant is not allowed to continue to discharge into Trout Creek following this period of adjustment, when it is shown that the Applicant's equipment is not performing as expected. In any event, the discharge of effluent into Trout Creek will continue over a limited period of time and the system can be expected to quickly return to its healthier state after the removal of the discharge from Trout Creek. This has occurred in the past when the operations of the plant ceased and occurred at a time when the wastewater was of a more damaging quality than contemplated by that associated with the DAF unit. In summary, it would be a reasonable policy choice to allow the interim discharge into Trout Creek on this occasion. Dredge and Fill Permit Characteristics of Pipeline Corridor The pipeline corridor encompasses portions of Trout Creek, Palmo Cove and the St. Johns River. The bottom sediments where the pipeline is to be installed are constituted of soft, and sometimes extremely soft, flocculent silt. Although these sediments are easily resuspended, dispersement of these sediments will only occur while the pipeline is being installed. In placing the pipeline, it is the intention of the Applicant to simply allow the pipe to sink into the sediment. The soft substrate is several feet deep in some places within the proposed corridor. Nonetheless, the pipe is expected to stabilize as it sinks into the material. There are places within the corridor where a crusty material may be found on the surface of or just beneath the substrate. These are locations where jetting or mechanical excavation may be necessary. Jetting may also be necessary along the approximately 155 foot stretch of the corridor that crosses the State of Florida, Department of Transportation right-of-way. This requirement would occur in view of the fact that the Department of Transportation mandates that the pipeline be at a minimum of 30 inches below the creek bottom. In those instances where jetting or other mechanical excavation might be utilized, silt screens would be used to control the short term turbidity. In the areas within the pipeline corridor where tree trunks and branches have been found, these obstructions can be removed without incident. Taking into account the nature of the substrate, at the location where the diffuser will be placed at the end of the pipeline, special attention will be given to that installation to avoid having the diffuser settle into the soft silty material. Given the fact that the silty material is several feet deep and the related fact that the Applicant has not done specific testing of the depth, density and compressibility of this silty material, careful attention should be given to anchoring the diffuser and making certain that the exhaust ports within that device are correctly positioned. The need for this close attention is borne out by the fact that a test pipe which was placed in the silty material settled approximately two and a half feet within several weeks. The matter of the security of the diffuser is also critical, given the fact that the diffuser will be located within one foot of the bottom. Through proper installation, the Applicant can avoid having the diffuser settle into the silty material over time. The installation techniques satisfactorily address the potential problems. Projected Impacts (1) Environmental The icthyological and macroinvertebrate communities within the pipeline corridor have been examined by the Applicant in the person of his consultants. It was found that there are a variety of freshwater fishes within Trout Creek, such as large-mouth bass and sun fish, and a moderate density of macroinvertebrates. The St. Johns River proper is dominated by estuarine and marine aquatic organisms. Infaunal macroinvertebrate densities in the area of the pipeline corridor in the St. Johns River are not high. In placing the pipeline, the effects on aquatic and benthic communities within the corridor or upon water quality do not pose a threat to those communities or to water quality. During the installation of the pipeline, some disturbance of the benthic organisms can be expected; however, those organisms will be able to recolonize quickly. The mere presence of the pipeline is not expected to cause long-term impacts on biological resources or water quality. (b) Navigation In the area of the intended placement of the pipeline related to Trout Creek, boating clubs utilize that vicinity for purposes of anchorage. Those clubs have as many as twenty to thirty boats whose size varies from twenty to fifty-five feet in length. Some of those boats carry anchors which can weigh forty-five pounds or more. Typically, in anchoring one of these craft, the anchor rope is tied down and the engines reversed to set the anchor. Although testimony was given to the effect that the anchors being set might puncture the pipeline, given the explanation about the placement of the pipeline and the nature of the pipe itself, problems with puncturing the pipeline as it might interfere with navigation or environmental concerns such as turbidity plumes due to a puncture of the pipeline are not expected. Nor are the activities associated with retrieval of the anchors via the use of electric winches or hoists seen to be a problem in the sense of snagging the pipeline and rupturing the pipeline when the anchors are brought aboard the vessels. In summary, the pipeline will not be an interference to navigation in the sense of boat anchorage or other aspects of navigation associated with boating. Moreover, the Applicant is willing to indicate the location of the pipeline on navigational charts to assist boaters in avoiding potential problems with anchorage. This is a desirable arrangement and should be done. Comparison of Projected Impacts with Statutory and Regulatory Criteria The dredge and fill activities associated with the pipeline are not expected to cause long-term or short-term adverse impact on biological resources or water quality, or are they expected to interfere with the conservation of natural resources or marine productivity or interfere with navigation to such an extent to be contrary to public interest. The placement of the pipeline will not promote unacceptable interference with fish and other natural resources or destroy clam beds or grass flats, such as would be contrary to the public interest. Permit Conditions Appropriate permit conditions are as follows: Installation of the pipeline shall be conducted within Trout Creek only during weekdays. Pipeline installation activities within Trout Creek shall not block navigation. The pipeline shall be constructed within 60 days following the receipt of all necessary approval, to include the grant of an easement by the State of Florida, Department of Natural Resources for the placement of the pipeline over submerged sovereignty lands. All conditions set forth in the DER draft permit. See Applicant's Exhibit A-57.
