The Issue The issue posed herein is whether or not the Respondent, Arthur M. Jones, Jr.'s Wastewater Treatment Plant Operator's license should be suspended or revoked based on conduct set forth hereinafter in detail based on allegations as set forth in the Petitioner's Administrative Complaint filed January 31, 1979.
Findings Of Fact Based upon my observation of the witnesses and their demeanor while testifying, the arguments of counsel and the documentary evidence received, the following relevant facts are found. Respondent, Arthur M. Jones, Jr., is a duly certified Class C Wastewater Treatment Plant Operator, certified pursuant to Chapter 17-16, Florida Administrative Code. Respondent holds license No. 793 originally issued by the Florida Department of Health and Rehabilitative Services on May 13, 1971. The responsibility for certification of wastewater treatment plant operators was transferred to the Florida Department of Pollution Control by Executive Order 72-75. The Florida Department of Environmental Regulation is the successor agency to the Florida Department of Pollution Control by virtue of Chapter 75- 22, Laws of Florida, and is authorized by Section 403.101, Florida Statutes, to issue and revoke operators' certificates pursuant to its rules and Chapter 120, Florida Statutes. At all times material to this complaint, Respondent was employed by the Duval County School Board in Jacksonville, Florida. At all times material, Respondent was employed by the School Board as a School Sewer/Water Plant Mechanic, a position requiring certification by the Department as a Wastewater Treatment Plant Operator. In his capacity as a School Sewer/Water Plant Mechanic and Class C Operator, Respondent was responsible for the operation, supervision, maintenance and collection of influent and effluent samples from various Duval County schools. Persons responsible for the operation, supervision, maintenance and collection of influent and effluent samples must be licensed and certified by the Department as a Wastewater Treatment Plant Operator. Additionally, Respondent, in his capacity as a School Sewer/Water Plant Mechanic and Certified Class C Wastewater Treatment Plant Operator, was responsible for the proper collection of composite samples of raw sewage and the treated effluent from each such plant. According to instructions given the Respondent, a composite sample was to be taken by filling one-third of a sample bottle at two-hour intervals until the bottle was full. The composite sample of raw sewage was to be taken from the influent line and the composite sample of treated final sewage was to be taken from the effluent line. After the collection process, Respondent was responsible for properly and accurately labeling the composite samples and for depositing them in a refrigeration unit at School No. 98. The composite samples are then picked up at School No. 98 by authorized personnel for laboratory analysis to determine whether sewage is being adequately treated. The complaint, in summary fashion, alleged that the Respondent on or about February 15 and March 15, 1978, completely filled a raw sample bottle from the filter bed rather than from the influent line of the plant at School No. 94. That sample was submitted as a composite sample and placed in the refrigeration unit for pickup and analysis by laboratory personnel. Additionally, the complaint alleges that on February 15, 1978, at School No. 82, Respondent filled raw and final sample bottles for Schools Nos. 82, 64, 83 and 153, none of which were a proper composite sample. The samples, it is alleged, were all taken from School No. 82. The complaint alleges that similar acts occurred on March 15, 1978; on April 4, 1978 and April 11, 1978, all of which acts "constitute gross neglect and fraud in the performance of duties as an operator of a wastewater plant." Based thereon, the Petitioner seeks revocation of the Respondent's Class C Wastewater Treatment Plant Operator's license. L. L. Masters is Respondent's foreman and is in charge of the wastewater treatment plant facilities. Masters is Respondent's immediate supervisor. On March 15, 1978, Foreman Masters assigned Respondent the duties of taking composite samples of Schools 94, 64, 83, 82 and 159. Evidence reveals that Foreman Masters arrived at School 82 at 9:00 o'clock a.m. and departed at 2:00 p.m. Evidence also reveals that Foreman Masters had a clear view of the entire wastewater treatment plant and that it was impossible for the Respondent to enter and leave the treatment plant in a manner whereby composite samples could be collected without Foreman Masters seeing him. In this regard, Respondent's work orders reflect that he reported having arrived at School 82 at 10:40 a.m. and departed at 12:10 p.m. (Petitioner's Exhibits 5, 6, 7 and 8.) On April 4, 1978, Respondent was assigned to collect composite samples from Schools 72, 233, 76 and 208. (Petitioner's Exhibit 9.) Foreman Masters observed Respondent on April 4, 1978, with employee Carl Casey. Masters went to School 77 at 8:30 and Respondent was not there, although he had given a dispatcher a routing which would have taken him to School 76. When Foreman Masters noted that Respondent had not arrived at School 76 by 8:30 a.m., he took employee Carl Casey to School 233 and left Casey at School 233 while he returned to School 76. The Respondent was not there and Masters drove to School 208 where the Respondent arrived at approximately 9:30 a.m. It suffices to say that the Respondent then left for School 233 and arrived there at 10:30. From approximately 10:45 to 11:45, the Respondent was in the wastewater treatment area of School 233 and took three samples from the effluent line and three samples from the influent line at School 233 from the period 10:30 a.m. through 11:45 a.m. (Petitioner's Exhibits 9, 10 and 11.) Employee Pat Wilson testified that he accompanied Respondent on February 15, 1978, and that all samples were taken from the filter beds of Schools 98 and 82. Detective Jack C. Adams of the Jacksonville Police Department was assigned to the surveillance of Respondent on April 11, 1978. Detective Adams credibly testified that the Respondent did not take composite samples from the assigned schools as reflected by the work orders submitted by Respondent Respondent appeared and testified that one of the events for which he had been charged occurred as alleged; however, he testified that inasmuch as he questioned the procedures, he was of the opinion that since no harm was done, and since no school experienced problems, he is not guilty of gross neglect and fraud in the performance of his duties as an operator of a wastewater treatment plant as alleged. The evidence herein reveals that the Respondent was instructed as to the proper procedures for testing, collecting and preserving composite raw and final samples from wastewater treatment plants by his employer. He testified that he had attended a seminar wherein the instructions for such procedures were outlined to him and that he was given a manual on the methods for collecting raw and final samples. Barry McAlister, a certification officer for the Department, testified that Class C operators are instructed as to the proper procedures for collecting samples. Additionally, he testified that the submitting agencies rely heavily on the operators to properly collect samples which are submitted for analysis. Chapters 17-19.04, Florida Administrative Code, additionally set forth the sampling and testing methods for collection and preservation of composite samples. Although there was some conflicting testimony respecting the adherence to the procedures uniformly by the various wastewater treatment plant operators employed by the School Board, the undersigned is of the opinion that the Respondent was not at liberty to select and choose the manner within which he would collect composite samples for analysis by his employer in view of outstanding instructions which were in effect during his employment.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is hereby, RECOMMENDED: That the Respondent, Arthur M. Jones, Jr.'s license as a Class C Wastewater Treatment Plant Operator be suspended for a period of two (2) years. RECOMMENDED this 28th day of September, 1979, in Tallahassee, Florida. JAMES E.

The Issue Whether Respondent, John J. D'Hondt, as a licensed operator, should be disciplined for violations of Florida Administrative Code Rule 62-602.650(2), (4) and (4)(f).
Findings Of Fact Based upon the testimony and evidence received at the hearing, the following facts were established by clear and convincing evidence: Petitioner is the State agency vested with the responsibility of regulating Florida's air and water resources, administering Chapter 403, Florida Statutes (2006), and the rules promulgated in Florida Administrative Code Rule Chapter 62. Petitioner has the statutory authority to establish qualifications; examine and license drinking water and domestic wastewater treatment plant operators and to place an operator on probation; and issue, deny, revoke, or suspend an operator's license pursuant to its rules. Respondent is the owner, supplier of water, and licensed operator of the Double D Mobile Home Ranch's drinking water and domestic wastewater treatment plants located in Volusia County, Florida. He holds Certified Operator Drinking Water License No. 0000542 and Certified Operator Wastewater License No. 0006032. The Volusia County Health Department is a county health department that has been approved by Petitioner pursuant to Subsection 403.862(1)(c), Florida Statutes (2006), to enforce Chapter 403, Florida Statutes (2006), and the rules promulgated for the State's drinking water program for Volusia County. As a result of not having received Respondent's September 2004 MOR, by letter dated October 20, 2004, the Volusia County Health Department notified Respondent that MORs were to be submitted to the Volusia County Health Department by the tenth of the month following the month of operation. The November 2004 MOR was to have been submitted to the Volusia County Health Department by December 10, 2004. Respondent signed and dated the November 2004 MOR on December 12, 2004; it was received by the Volusia County Health Department on December 27, 2004. The December 2004 MOR was to have been submitted to the Volusia County Health Department by January 10, 2005. On February 4, 2005, Respondent was sent a late reporting violation letter stating that the December 2004 MOR had not been received. This letter again reminded Respondent that MORs were to be submitted within ten days after the month of operation. The December 2004 MOR was received on February 11, 2005. The April 2005 MOR was to have been submitted by May 10, 2005. Respondent signed and dated the April 2005 MOR on May 17, 2005. It was received on May 27, 2005. The September 2005 MOR was to have been submitted by October 10, 2005. It was received on October 18, 2005. The November 2005 MOR was to have been submitted by December 10, 2005. It was signed and dated December 14, 2005, and received on December 19, 2005. Respondent did not timely submit MORs for the months of November 2004, December 2004, April 2005, September 2005, and November 2005. In 2004, the Volusia County Health Department inspected the Double D Mobile Home Ranch's drinking water treatment plant and found that Respondent maintained a combined logbook for the drinking water and domestic wastewater treatment plants. Respondent was informed that he was required to keep a separate operation and maintenance logbook for each of the drinking water and domestic wastewater treatment plants. On August 10, 2004, Petitioner inspected the Double D Mobile Home Ranch's domestic wastewater treatment plant and found that there was a combined logbook for the drinking water and domestic wastewater treatment plants. Respondent was again informed that he was required to keep separate logbooks for each plant. A non-compliance letter dated October 12, 2004, and a copy of the August 10, 2004, inspection report were sent to Respondent informing him that he needed to separate his operation and maintenance logbook. In 2005, the Volusia County Health Department inspected the Double D Mobile Home Ranch's drinking water treatment plant and found that Respondent still maintained a combined logbook for the drinking water and domestic wastewater treatment plants. During the inspection, Respondent was again informed that he was required to keep a separate operation and maintenance logbook for the drinking water and domestic wastewater treatment plants. On June 15, 2005, Petitioner inspected the Double D Mobile Home Ranch's domestic wastewater treatment plant and again found that Respondent was keeping a combined logbook for the drinking water and domestic wastewater treatment plants. During this inspection, Respondent was again informed that he was required to keep separate logbooks. A non-compliance letter and a copy of the June 15, 2005, inspection report were sent to Respondent again informing him that he was required to maintain separate logbooks for the drinking water and domestic wastewater treatment plants. On February 13, 2006, the Volusia County Health Department inspected the Double D Mobile Home Ranch's drinking water treatment plant and found that Respondent still maintained a combined operation and maintenance logbook for the drinking water and domestic wastewater treatment plants. During this inspection, Respondent was again informed that he was required to maintain a separate logbook for each plant. Over the extended period reflected by the inspections cited in paragraphs 11 through 15, Respondent failed to maintain separate logbooks for the operation and maintenance of the Double D Mobile Home Ranch's drinking water and domestic wastewater treatment plants. On August 10, 2004, Petitioner inspected the Double D Mobile Home Ranch's domestic wastewater treatment plant and found that the logbook did not contain sufficient entries of the performance of preventative maintenance and repairs or request for repairs of equipment. During this inspection, Respondent was informed that he was required to keep adequate entries of preventative maintenance and repairs or request for repairs of equipment for the domestic wastewater treatment plant. A non-compliance letter and a copy of the August 10, 2004, inspection report were sent to Respondent informing him that he was required to maintain entries of the performance of preventative maintenance and repairs or request for repairs of equipment for the domestic wastewater treatment plant. On June 15, 2005, Petitioner inspected the Double D Mobile Home Ranch's domestic wastewater treatment plant and again found that Respondent was not keeping adequate entries of the performance of preventative maintenance or repairs for the domestic wastewater plant. During this inspection, Respondent was again informed that he was to keep such entries. A non-compliance letter and a copy of the June 15, 2005, inspection report were sent to Respondent informing him that he needed to maintain such entries for the domestic wastewater treatment plant. Photocopies of the combined logbook have essentially no entries for the performance of preventative maintenance or repairs or requests for repairs to a domestic wastewater treatment plant. Infrequent margin notes are not decipherable and do not differentiate between the two activities.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the licenses of John J. D'Hondt, as a Certified Operator Drinking Water and a Certified Operator Wastewater, be disciplined as set forth in the "probation" letter of March 15, 2006.

The Issue Whether Okaloosa County has provided reasonable assurances that its proposed sewage treatment plant and an associated reclaimed water reuse system will not cause pollution significantly degrading the waters of the unnamed stream on the project site and/or the Santa Rosa Sound and that therefore the County's application for a permit to construct such facilities should be granted on the basis of assurances of compliance with applicable rule and statutory criteria.
Findings Of Fact On October 16, 1987, Respondent, Okaloosa County, submitted an application to Respondent, Department of Environmental Regulation, to construct a wastewater treatment plant and related reclaimed water reuse facilities on a site located in southwestern Okaloosa County. The Petitioner is an individual citizen residing in Okaloosa County, Florida. He is the owner of real property which adjoins the northern boundary of the proposed project site. Mr. Ward has used this property as his principal residence for approximately 8 years. The proposed project site is located in southwest Okaloosa County contiguous to the western boundary of the County. The site comprises approximately 45 acres of land bounded on the west by Rosewood Drive and on the south by State Highway 98. The areas to the north and east are residential construction. The site is currently a densely wooded area vegetated with a variety of flora indigenous to the area. The site is essentially bisected by a small fresh water stream system which enters the site at the northwestern corner and runs diagonally to the southeastern corner where it flows through a series of culverts under State Highway 98. The stream system constitutes waters of the state subject to the Department's regulatory jurisdiction. In addition, there is an isolated wetland area of variable size in the northwestern section of the project site. The wetland area is not subject to the Department's regulatory authority. The stream system mentioned above intersects with another larger stream approximately 1000 feet southeast of the project site. These combined streams then meander into a tidal basin which empties into the Santa Rosa Sound approximately 2500 feet south of the project site. The Santa Rosa Sound has been designated as Class II waters of the state. The unnamed stream system on site, as well as the larger stream that it joins south of the site, are designated as Class III waters of the State. Southern Okaloosa County occupies a region of moderate elevation (0-70 feet above sea level) extending along a strip 10 or 15 miles wide along the coast of the Gulf of Mexico. Soils in this area are predominately fine sands low in organic matter. When dry, most of the soils have rapid internal drainage characteristics. The Plant The proposed plant is intended to treat sewage generated by the County's Western subregional service area. Initially, it will treat the flow currently handled by approximately 1400 septic tank systems and 9 package treatment plants within the area. The collection system which will transport the wastewater will be comprised of approximately 98,500 linear feet of 8 to 12 inch diameter gravity sewers. The transmission facilities to convey the raw wastewater from the new collection system will include the construction of approximately 29,400 linear feet of 4 to 10 inch diameter force main, 14 pump stations and approximately 32,100 linear feet of 8 to 12 inch diameter gravity interceptors. By the end of its first year of operation, the proposed facility is projected to receive and treat approximately 750,000 gallons per day ("GPD"). The projected flow through the wastewater facility in the year 2007 is 1,000,000 GPD. The proposed facility is best described as a 1,000,000 GPD capacity oxidation ditch treatment plant with nitrification and denitrification facilities. Reclaimed water reuse will be accomplished by a rapid infiltration basin system (RIB). Sludge from the system will be dewatered by a mechanical belt press system and disposed of at the County landfill. In order to address the question of potential odors which result from the operation of the plant, the facility was located as near the center of the property as possible in order to give as much buffer area as possible between the facility and the surrounding residential area. In addition, the design of the treatment facility incorporates a preprocess aeration tank equipped with an activated carbon airstripper system which is specifically designed to remove the odor from the wastewater influent. The treatment facility was also located near the center of the property in order to keep any noise resulting from the operation of the plant as far away from the surrounding area as possible. The plant utilizes noiseless gravity flow techniques and does not incorporate any blower or pump technology which usually cause a significant amount of noise in wastewater treatment plants. It is expected that the noise level from the operation of this facility would be less than the noise level generated from the traffic on State Highway 98 nearby. The plant is designed to minimize the adverse effects resulting from odors, noise, aerosol drift and lighting. The entire facility is enclosed by a fence. The facility is designed and does comply with the Florida Administrative Code requirements for protection from flooding. The proposed site is at a higher elevation than the established 100 year flood elevation for the area. The plant is designed so that every operational component of the plant has a backup system. The plant is equipped with an emergency generator capable of supplying sufficient power to operate the plant in the event of a power failure. The design of the plant complies with the standards provided by the Environmental Protection Agency for mechanical reliability. The information submitted for the Department's review in relation to the County's construction permit application addressed all the information required in Rule 17-6.037(10), Florida Administrative Code. The proposed plant facility is designed to leave a buffer zone approximately 200 feet wide between the reclaimed water reuse system and the stream system located on the project site. The construction plan prohibits any construction activities and/or clearing within the buffer area. This buffer area contains all the jurisdictional areas which are related to the stream system. The Treatment Process The waste treatment process proposed for this facility consists of secondary treatment, basic disinfection and pH control as defined in Rule 17- 6.060(1)(a)3, (c) and (d). The basic treatment process technology used in the proposed plant is described as a carousel activated sludge process. This process is a superior method of wastewater treatment because of its inherent stability, its reaction to shock and toxic loadings and the degree of process control that is available to the operator. The effluent limitations that the Department has established for this facility require that the effluent, after disinfection, contain not more than 20 mg/1 Biological Oxygen Demand ("BOD") and 20 mg/1 Total Suspended Solids ("TSS"). In addition, effluent standards require a basic level of disinfection which shall result in not more than 200 fecal coliform values per 100 ml of effluent sample. The chlorine residual in recovered water shall be maintained at 0.5 mg/1 minimum, after 15 minutes contact time at peak flow. The pH level in the effluent must be maintained in a range between 6.0 Q and 8.5. The County will be required to retain a Class B operator certified under the provisions of Chapter 17-16, Florida Administrative Code for day-to- day maintenance and operation of the treatment facilities. In addition, the facility must be staffed for a minimum of 16 hours per day, seven days a week by at least a Class C operator certified under the same provisions. A Class B operator shall be on call during all periods that the plant is unattended. At a minimum, the facility must produce reclaimed water which complies with water quality standards provided in Rule 17- 3.404, Florida Administrative Code, as it interacts with groundwater in the established zone of discharge ("ZOD"). The estimated ZOD is an area defined by the boundaries of the facility. These standards are essentially equal to drinking water standards provided in Rule 17-22, Florida Administrative Code. Because the soils under the site are rapid sands, the Department does not rely on them to significantly reduce total nitrogen in the reclaimed water through interaction with the soils and the groundwater table under the rapid infiltration basins. As a result, the proposed facility is limited to a Total Nitrogen limitation of 7 mg/1. This limitation is significantly less than the Department's rapid rate land application treatment standard for Total Nitrogen which is 12 mg/1 in the effluent, with no more than 10 mg/1 in the ground. The proposed plant is capable of producing the 7 mg/1 level under all flow conditions. The Rabid Infiltration Basins In conjunction with the County's application for a construction permit for the wastewater treatment plant itself, the County submitted an application for a reclaimed water reuse system construction permit for a system designed to handle the maximum plant discharge of 1,000,000 gallons of reclaimed water per day. The system is composed of a series of five rapid infiltration basins (RIB's) or percolation ponds designed to receive the daily reclaimed water loads from the operation of the plant and allow the water to percolate into the groundwater beneath the project site. The ponds are proposed to be used so that not all the ponds are working at the same time. On any given day, there will be 3 ponds receiving effluent from the plant and 2 ponds receiving no effluent. The proposed system of rapid infiltration basins is the best approach to effluent disposal on this particular site in consideration of a variety of site specific criteria. While the Department's adopted guidance standards for percolation pond location specifies that areas with average depths to the groundwater table of 10 feet or more are desirable, the guidance document provides that areas with lesser depths may be acceptable. Computer models using highest projected groundwater levels and highest reasonably projected mounding effects related to the effluent disposal system indicate that while at times there may be less than 3 feet of vertical separation between the top of the groundwater mounds beneath any one of the percolation ponds and the floor of those ponds, it is not expected that the groundwater level will intersect the bottoms of the infiltration basin and that an acceptable margin will be maintained. Initially, there was some dispute among Department staff concerning the suitability of the project site to handle the hydraulic loading rates proposed for the facility's pond system. After a significant amount of analysis of the relevant factors affecting site suitability in this regard and after Department staff managed to get the computer program which analyzes this data working properly, the relevant data indicates that the site is suitable for the proposed wastewater treatment plant as designed. Surface and Ground Water Impact The proposed facility is designed to meet applicable Department water quality standards necessary to prevent unacceptable degradation of the water quality in both the unnamed stream system on site and the Santa Rosa Sound. At the Department's request, the County had an independent study performed to assure that the operation of the facility would not have the effect of degrading nearby surface waters. This study, done by Larry Jacobs and Associates, supports the County consultant's projections that, under worst case conditions (highest observed groundwater levels plus maximum effluent loading), approximately 32,000 additional gallons per day of groundwater may enter the stream system as a result of operation of the RIB system. These studies were conducted to address the Department's concern about the potential for increased nitrogen loading into both the stream system and the Santa Rosa Sound as a result of increased groundwater contributions to the stream system on site. The effluent disposal study submitted by the County as part of its application concludes that, discounting any possible reduction of Total Nitrogen content of the effluent as it travels through the ground before its discharged into the stream system, the Total Nitrogen concentration of the groundwater predicted to reach the stream should be diluted at the lowest observed flow volumes in the system to a concentration of less than 1 mg/1 when it reaches the confluence of the two streams approximately 1,000 feet south of the project site. The projection is an improvement in surface water conditions when compared with currently observed average concentrations of Total Nitrogen in the stream system and Santa Rosa Sound of 1.24 mg/1. The performance of existing package plants in the area is generally poor. In fact, one treatment plant was ordered to close, forcing the relocation of residents in its service area. Another plant has continuing groundwater nitrate violations. In addition, the evidence shows that the performance of the septic tank systems in the area is not acceptable to the Environmental Protection Agency. The majority of the population is served by septic systems that fail under high groundwater conditions. The Director of the Okaloosa County Health Department has certified that 60% of the residents in the County West Service Area have failed septic tanks and that the remaining 40% have septic tanks in imminent danger of failing. Three of the eight existing treatment plants are under either Court or Consent orders to cease operations. The United States Environmental Protection Agency has found that the County West area has an immediate need to provide collection, transmission, and treatment facilities to protect surface and groundwaters and eliminate a public hazard. Existing concentration of Total Nitrogen in Santa Rosa Sound and the waterways on and adjacent to the site are attributed to discharge of inadequately treated wastewater from existing septic tanks, existing wastewater treatment plants and stormwater runoff in the area. It is unlikely that the nitrogen concentration in the Santa Rosa Sound will increase as a result of the operation of the proposed facility since whatever wastewater treated at the facility will be eliminated from discharging into the affected waterbodies from other, less efficient treatment facilities. The proposed facility design incorporates a total of seventeen monitoring wells or stations on and around the site. Two wells will monitor background groundwater quality upgradient from the percolation pond system. Twelve wells will monitor groundwater quality down gradient from the percolation pond system as it leaves the established zone of discharge. Two more stations will monitor surface water quality in the on-site system above and below the site. In addition, there is one intermediate monitoring well within the zone of discharge. Samples from these wells will be used to provide quarterly data reports to the Department indicating status of the following parameters in the ground water; water level, pH, BODs, Fecal Coliform, Total Nitrogen, Nitrate/Nitrate and Chloride. The surface water monitoring will provide annual data reports to the Department on the following parameters: Chemical/Physical - Total Nitrogen, Nitrate/Nitrate, Total Phosphorus, Dissolved Oxygen, Temperature and pH Biological Assessment - macroinvertebrate population per species, species diversity per square meter. These data reports will be submitted regularly to the Department in conjunction with operational monitoring data from the treatment plant to allow assessment of the impact of the plant operation on the environment and compliance with permit conditions. Clearly the County has provided reasonable assurances that the proposed plant and related facilities will not cause pollution significantly degrading the waters of the State.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Regulation enter a Final Order Granting the application of Okaloosa County to construct a wastewater treatment facility and related reclaimed water reuse system at the proposed site in southwestern Okaloosa County, Florida, and issuing permits in accordance with the conditions as set forth in the Department's Intent to Issue and draft permit dated August 1, 1988.

The Issue Whether Gar-Con's revised application for a permit to construct a sewage plant, and soakage trenches to dispose of the effluent, should be granted?
Findings Of Fact Eight to ten miles south of Melbourne Beach and 8.3 miles north of Sebastian Inlet, Gar-Con plans to develop a parcel of land stretching west from the Atlantic Ocean, across Highway A1A, to the Indian River. Gar-Con expects to build a motel and residential complex complete with tennis courts, parking garage, water treatment plant and the sewage treatment facility for which a construction permit is sought in these proceedings. The sewage treatment plant would be built on a site 480 feet west of Highway A1A and 90 feet south of Gar-Con's northern property line, at an elevation of 11 or 12 feet above mean sea level. Ocean Way Water and Sewer Association, Inc. is to be organized as a nonprofit corporation to own and operate the wastewater treatment facility. The Public Service Commission, through the director of its water and sewer treatment, has taken the position that the proposed "sewer system will fall within the exemption described in Section 367.022(7), Florida Statutes." DER's Composite Exhibit A. PACKAGE PLANT PROPOSED The facility Gar-Con proposes is designed to treat 100,000 gallons of sewage daily, which is the estimated "total flow" (T. 75) the sanitary engineer who designed the system anticipates from the development. Sewage generated by the development would flow to the plant, through a bar rack designed to remove rags and other large objects, and into aeration tanks where, over a 24 hour period, interaction with air and a biological mass would supply oxygen and cause the formation of biological floccules. The flocculant sewage would then move to a clarifier hopper. During its five hour stay there, solids which were not earlier segregated as the sewage moved over a weir into the clarifier, would be precipitated and removed. The clear, residual liquid would be pumped through one of two sand filters (each of which would also have granular activated carbon and be capable of filtering 100,000 gallons daily) into one of two chlorine contact chambers where a gas chlorinator would introduce chlorine for an hour. Under ordinary circumstances, the chlorinated effluent would then be pumped into one of two soakage trenches. The soakage trenches, each designed for use every other week, are to be gravel-filled ditches covered over first with felt paper, then with compacted fill. The gravel would lie at least one foot beneath the surface of the ground in a space ten feet wide and three feet deep stretching the 940 foot length of each soakage trench. Punctured like sieves, two six-inch PVC pipes would run through the gravel, sweating effluent from their pores. There is also a plan to dig a percolation pond or grassed swale five feet deep, 120 feet long and 80 feet wide near the wastewater treatment plant, which could serve as a receptacle for effluent, in case of "a 1:10 year storm or when the filters are down and/or if soakage trenches would need repair." Gar- Con's Exhibit 2-A. It would hold about 100,000 gallons. The solids caught by the weir, those extracted in the clarifying process, and those recovered from backwashing the filters would serve as catalyst for the aeration process as needed. Excess sludge, about 3,000 pounds monthly, would undergo "aerobic digestion," before being removed to Brevard County's Central Disposal Facility on Adamson Road, for disposal there. Gar- Con's Exhibit No. 7. Primary and secondary drinking water standards would be met by the effluent as it left the plant (although the engineer who designed the system would not drink the effluent himself), except that, from time to time, nitrate concentrations might reach 12 milligrams per liter, and except in the "event that a homeowner might put some type of [inorganic toxic or carcinogenic] material into the sewer system." (T. 86) The biological oxygen demand (BOD) would be ten milligrams per liter; suspended solids would probably amount to about five milligrams per liter; pH would probably be slightly under seven; nitrates would average approximately eight milligrams per liter but would "peak out at certain times during the year, for maybe extended periods up to two months, at twelve milligrams per liter," (T. 80); and there would be a chlorine residual after 60 minutes of two milligrams per liter. AMBIENT WATERS There would be no direct discharge to the Atlantic Ocean, Indian River or any other body of surface water, nor would any indirect effect on surface waters be measurable. No body of surface water lies within 500 feet of the site proposed for the plant and soakage trenches. Potable groundwater underlies the site; the groundwater table slopes toward the Atlantic Ocean, 9.5 to 12.5 feet below ground. "[D]uring the traditional rainy season," Gar-Con's Exhibit 2B, Attachment, p.3, the groundwater may rise to within seven feet of the surface. The PVC pipes in the soakage trenches are to be placed two and a half feet deep. As effluent percolated through the sandy soil, there would be "mounding" of the groundwater underneath the soakage trenches, and dispersal in all directions. Surface flow is to be diverted from the soakace trenches so that only rainwater falling directly on them would percolate down through the gravel beds. Taking soil characteristics into account, and assuming a "water table depth" of 20 feet, an engineer retained by Gar-Con predicted that "the maximum expected groundwater rises beneath the east and west trenches are 2.4 and 2.1 feet, respectively under a loading of 100,000 gpd for a period of 7 days." Gar-Con's Exhibit No. 3. The water table depth, "the height, the top of the groundwater from the first restrictive layer," (T. 172), is probably more like 40 feet than 20, which accounts in part for the "conservatism" of the mounding predictions. Under very severe weather conditions (a 100 year storm), groundwater would rise as high as the bottom of the trenches making them unavailable to receive effluent, but the effluent would not be forced above ground. In a 100 year flood, water would be expected to rise to seven feet above mean sea level. Under such conditions, people could be expected to evacuate the area. In a 25 year storm, the system could be expected to continue to function. Groundwater to the north and east of the proposed site was sampled, and the samples were analyzed. The water to the north had 380 milligrams of chlorides per liter and the water to the east had 450 milligrams of chlorides per liter. As it left the proposed treatment plant, the effluent would contain approximately 150 milligrams of chlorides per liter. SOUND AND LIGHT Lights like those used as street lights are to be installed at four places in the wastewater treatment plant. A timer, which can be overridden, would turn the lights on at dusk and off at eleven o'clock at night. The lights would illuminate the plant adequately. Pumps would move sewage to and through the proposed plant. Most of the pump motors would be submerged and unable to be heard. Two electric blowers, a flow meter and a totalizer would also have electrical motors. The blowers and the blower motors are to be equipped with insulated fiberglass covers and the blowers would also have intake and double outlet silencers. Four feet from the plant the noise of the motors would be comparable to that of a home air conditioning unit. At the nearest residence the noise level would scarcely exceed background noise. At hearing, Gar-Con revised its application and agreed to install an emergency generator which would also be encased in insulated housing and is to be equipped with a muffler. AEROSOL AND ODOR Unless the proposed plant loses electric power for 24 hours or longer, no offensive odors would emanate from it. The bar rack and weirs would be regularly hosed down. Against the possibility of a power failure, Gar-Con agreed at hearing to install permanently an emergency generator with sufficient capacity to keep both the wastewater treatment plant and the water treatment plant it plans to build operable. No aerosol drift is foreseen. The surface of the liquid In the aeration tanks would be 1.4 feet below the top of the rim. Walkways four feet wide along the inside perimeters of the aeration holding tanks would prevent dispersal of most of aerosol. A decorative hedge around the treatment plant, which would eventually be 15 feet high, is a final fail-safe. WELLS To the north are two shallow wells within 500 feet of the site proposed for the wastewater treatment plant. Both wells belong to Kel Fox, who wrote Gar-Con that he had no objection to their proposed wastewater treatment facility in light of Gar-Con's agreement to furnish drinking water to existing facilities on his property and reimburse him expenses incurred in disconnecting the two shallow wells. Gar-Con's Exhibit 2E. There is a deep well within 500 feet to the south. DER and Gar-Con have entered into the following stipulation, dated September 2, 1983: Existing Wells. Prior to the operation of its waste water treatment plant, Gar-Con will offer to supply drinking water at a reasonable cost to owners of property on which are located operational or approved shallow drinking water wells that are within 500 feet of Gar-Con's land application site. Gar-Con will make this offer to all such owners known to it prior to the operation of its plant. Gar-Con will further offer to provide reasonable compensation to such owners to disconnect their shallow wells. Gar-Con will endeavor to arrange for provision of drinking water to these owners and the disconnection of those wells prior to the operation of its plant. Future Wells. Should nearby individual (non-corporate) property owners propose to construct shallow drinking wells located within 500 feet of Gar-Con's land application site after Gar-Con begins operation of its waste water treatment plant, Gar-Con also will offer to supply them with drinking water at a reasonable cost and to provide reasonable compensation to them to disconnect those wells. However, Gar-Con shall have no obligation to make any such offer to owners of future wells if sampling of monitoring wells located at or near its external property line indicates that the groundwater meets the primary drinking water standards and, after July 1, 1985, the secondary drinking water standards listed in Florida Administrative Code Rule 17-22.104. Gar-Con agrees to record a master notice of restriction barring future owners of lots within the Ocean Way development, which are owned by Car-Con at the time of permit issuance, from installing shallow drinking water wells on such property or otherwise using the shallow aquifer beneath their property as a source for irrigation or for potable water, so long as use of the proposed sewage disposal system continues, and the Department has not found that this restriction is unnecessary. This restriction, which shall be a covenant running with the land, further shall require future owners to purchase water from Gar-Con or any successor owner of the development's water system if Gar-Con or the successor provides water service. These restrictions also shall be contained in all other appropriate documents of title. In addition, Gar-Con plans to create a non-profit water and sewer association to own and control the development's water and sewer system. Gar-Con will include in the Articles of Incorporation of this association a requirement that all property owners served by the system must be members of the Association. Gar-Con is entitled to a zone of discharge extending to its current property line with the exception that the zone of discharge shall not include the area contained within a 100' radius of Gar-Cons's proposed water supply wells. DER Staff concurs that the above conditions, in conjunction with the sewage treatment and disposal system and the groundwater monitoring program proposed by the applicant, to meet the requirements of Chapter 17-4, F.A.C. will provide reasonable assurance that existing and future off-site and on-site property owners will be protected from any adverse effects that might result from the operation of the proposed sewage treatment disposal system. Petitioner's Exhibit No. 10. There are to be a half dozen monitoring wells to allow sampling of the groundwater at strategic points in the shallow aquifer. NATURAL RESOURCES Turtles nest in the general vicinity but off the site of the proposed project. Construction and operation of the proposed waste water treatment facility would have no impact on the turtles apart from making it possible for more people to live closer to where they nest.
Findings Of Fact Respondent/applicant, Kensington Park Utilities, Inc. (applicant), is a public utility located in Sarasota, Florida. On October 12, 1984, applicant filed an application with respondent Department of Environmental Regulation (DER); seeking approval to construct a domestic wastewater treatment and disposal system in an unincorporated area of Sarasota County Florida. 1/ More specifically, the project will be located on a thirty-five acre tract of land lying west of Tuttle Avenue and north of 27th Avenues just northeast of the City of Sarasota. It is directly east of a housing development known as Newtown Estates. A drainage ditch separates the two properties. Petitioners, Eddie Lee Rosier, Sr. and Ernest Dubose, either live in or near the Newtown subdivision. Petitioners, Alfred W. Jones and Mary James did not testify at final hearing and their interest in this matter is not of record. Petitioner, Newtown Homeowners Association, Inc., is a nonprofit corporation made up of homeowners or residents in the Newtown housing development. In this proceeding petitioners oppose the manner in which the project will be constructed as well as its location. Applicant proposes to construct a 175,000 gallons per day capacity expandable extended aeration wastewater treatment system with effluent disposal to two percolation holding ponds of 125,000 square feet each and spray irrigation of a 3.2 acre site. The 3.2 acre spray area will serve as a backup to the percolation ponds. There will be total retention of effluent onsite, and none will be discharged to the ditch which separates Newtown and Kensington's property. The estimated cost of the project is $500;000. The project is designed to serve the present population of 1,750 until regional sewage treatment becomes available, at which time this plant will be shut down or tied into the regional system. If constructed, this plant will serve the western portion of its franchise area including Newtown Estates, Windmill Villages and Rolling Green. The entire plant site will be fenced with a locked gate in accordance with a Sarasota County ordinance. Applicant is subject to the regulatory control of both DER and Sarasota County (County). The County has established a local pollution control program pursuant to Section 403.182, Florida Statutes. As such, applicant is required to obtain permitting approval from both the County and DER. In this regard, applicant's plans and specifications were reviewed by both DER and County personnel and both made on-site inspections of the property in question. All DER and County rules, regulations and standards were found to be met. Specifically, applicant has given reasonable assurances that the proposed project will not discharged emit or cause pollution in contravention of DER standards or rules. Further, the proposed groundwater discharge will not cause significant adverse effects to the designated uses of the adjacent groundwaters. This was not controverted by petitioners. Petitioners' objections fall into four broad categories. First, they challenge the location of the project, and particularly its placement on the most westerly portion of a tract of undeveloped land which lies immediately adjacent to Newtown and a recreational area. Because of this, they fear that spray from the spray irrigation site will drift onto their homes and picnic area when easterly winds prevail. However, a 150 foot setback has been established in accordance with agency rules, and "downsprays" will be used to prevent such an occurrence. Second, they are concerned that in the event of an "emergency , raw sewage containing virus and bacteria may be dumped into the drainage ditch adjacent to their property. However this concern is unfounded. If an unanticipated emergency arose, only overflow water from the percolation ponds would be discharged into the ditch, and by that time the water would be 90 percent free of contaminants. Moreover, in the event of an emergency, applicant's facility is capable, with only minor modifications, of discharging effluent to another plant approximately two miles away. Third, petitioners are concerned that the plant will emanate a noxious odor which because of petitioners' proximity, will make living conditions in the Newtown area most undesirable. They point out that a city-owned sewage plant on 12th street which is a mile away emits noxious odors that can be detected in the Newtown area. However, petitioners' own expert concedes the plant's design is the "best design" possible for eliminating odors, and only through an unplanned malfunction could an odor occur. Moreover, applicant's plant is far superior to the city's; and is designed to eliminate the type of odor that is emitted from that facility. Finally, petitioners suggest that if raw sewage is dumped into the drainage ditch, it may eventually seep into "the underground water system" and endanger the well water of persons living immediately south of the project. But since no raw sewage will be discharged, this concern is without merit. This finding is corroborated by expert testimony of witness Suttcliffe who concluded that the treatment process posed no threat to surrounding groundwater. Other contentions relating to the utility's hookup policy its potential for accidents involving neighborhood children, and the alleged diminishment of property values in the immediate area, while well intended are not within the purview of DER's regulatory scheme.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the agency issue a permit to applicant as reflected in the agency's notice of intent to issue dated March 17, 1985. DONE and ORDERED this 23rd day of July, 1985, in Tallahassee, Florida. Hearings Hearings DONALD R. ALEXANDER Hearing Officer Division of Administrative The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative this 23rd day of July, 1985.
Findings Of Fact Respondent City of Okeechobee (City) has applied to the Department of Environmental Regulation (Department) for a permit to construct a 0.6 mgd sewage treatment plant with land spraying as the method for effluent disposal. The facility will be used to provide secondary treatment of domestic waste for the City of Okeechobee. The location of the facility site will be north of the City of Okeechobee on Cemetary Road. It will be adjacent to R- Bar Estates, a residential subdivision, and the Florida School for Boys. This site is a suitable land site for the facility. Analysis of other sites has not produced a better site for the project. The waste material will be introduced into the plant where some solids will be removed. The wastewater will then move into the treatment tanks where bacteria will assimilate the nutrients. With secondary treatment, approximately 90 percent of the nutrients will be removed. The treated wastewater will then be disinfected with chlorine so as to maintain a chlorine residual of 0.5 ppm. The chlorination should destroy most if not all of the bacteria in the effluent. The method of treatment described above is a standard method. The design of the plant itself is quite common and, with the changes recommended by the Department, should be simple to maintain and should provide an acceptable level of treatment. If the plant is operated properly, the wastewater will meet all Department standards for secondary sewage treatment. Petitioner introduced no evidence at the hearing to establish that the plant itself could not be properly constructed or that the plant could not meet treatment levels. There are no noises or lighting at the plant which would carry to any residential areas. The plant itself is well removed from R-Bar Estates. While the sprayfields are located near R-Bar Estates, the only noise associated with the effluent disposal will be that of the small electric motor used to move the spray bars. The entire site will be enclosed by a fence so as to restrict access. The facility has been provided with a flow meter and with raw wastewater and finished effluent taps. The treated effluent from the plant is to be disposed of on sprayfields adjacent to the facility. Combined area of the sprayfields will be 310 acres. The sprayfield area consists of seven separate sprayfields. Each sprayfield will receive 1/2 inch of effluent per week, with each field receiving effluent one day per week. Prior to disposal of effluent, the entire site will be graded so as to eliminate low areas. Elimination of low areas on the site will reduce the possibility of effluent ponding on the site. The entire area of the sprayfield will be surrounded by a dike. The dike will prevent any surface waters or effluent from leaving the site. There will be no contamination of any waters from surface water runoff from the site. The facility has the capacity to store effluent for 90 days in the event of an unusually wet rainy season. That capacity allows the plant to retain all effluent for 90 days without any discharge in the event the sprayfields become saturated. The size of the pond may allow for some mosquito propagation but no mosquito problem is anticipated if the project is done properly and maintained. Mosquito propagation in holding ponds does occur in Florida. However, in every holding pond in which mosquito propagation has become a problem, it has been controlled by proven management techniques. The most common method of eliminating areas for mosquito propagation is to keep the side slopes of the pond free from vegetation. However, if that is not effective, adequate control may be achieved by use of chemical larvicides. In a pond of this size, chemical use is not as practical, but nonetheless remains as an alternative. The City of Okeechobee already owns the machinery necessary to mow around the perimeter of the pond. The holding pond area includes a separate pond which will accept effluent during times in which the plant upsets. During an upset, hydraulic or other factors may result in the plant producing inadequately treated effluent. That inadequately treated effluent will be pumped back to the head of the plant for further treatment. During the treatment process, ozone will be injected into the raw sewage. Ozone serves to reduce the smell of the sewage. Between the ozone treatment and the treatment at the plant, the finished effluent should have a very slight and innocuous odor. The application of effluent shall be accomplished by two methods. In four fields, effluent will be sprayed by an irrigator which moves in a circle from a central pivot. The effluent is sprayed down to the ground, thereby eliminating potential for aerosol drift. In the three fields furthest from inhabited areas, effluent is sprayed by a rolling unit which is pulled across the sprayfield. Trees and other vegetation at the property boundaries will eliminate any aerosol drift which may occur. There is a buffer of 200 feet from the edge of the sprayfield to the property boundary. It is in excess of 400 feet from the edge of the sprayfield to the nearest drinking water well. This distance should be adequate to keep any contaminants from reaching wells offsite. The nearest wells are all fully encased wells at approximately 100 feet or greater in depth. The plant described in the application and drawings is designed to provide Class I reliability pursuant to Florida Administrative Code Rule 17-6.040(4)(m). The primary constituents of the effluent will be water, nitrogen and phosphorus. Vegetation utilizes nitrogen and phosphorus in its growth process. When treated effluent is sprayed on a field, much of the nutrients remaining after treatment are assimilated by vegetation on the fields. Therefore the vegetation provides additional treatment for effluent beyond that provided in the plant. The types of vegetation to be grown in the Okeechobee sprayfields are Pangola grass and rye grass. Pangola grass, which is recommended for the area by the Soil Conservation Service, is a commercially valuable hay. Okeechobee intends to have a person contract with the City to harvest the hay four times per year. During the winter, when Pangola grass is dormant, rye grass will be planted and utilized to provide the same treatment. The facility will be surrounded by a series of monitoring wells which will allow early detection of contaminants leaving the property boundary. The wells will measure upstream and downstream groundwater. Nitrogen and phosphorus are not health related components of effluent. They are nutrient related standards and must exist in extremely high concentrations to have a health risk. However, if the monitoring wells pick up levels of nitrogen or phosphorus leaving the site boundary, a fund has been established for the construction of water mains to R-Bar Estates to provide residents of the area with city water. An adequate water supply to R-Bar Estates is assured. The soils in the project area consist of Myakka and Imokolee fine sand with pockets of other fine sands. An organic pan exists at elevations from 24 to 35 inches below the surface. The organic pan acts as a semi-confining layer. The permeability rate of the sands is approximately 12 feet per day. The organic layer rate is from 4 to 12 feet per day. As a part of the site preparation, the organic layer will be deep plowed to break up the layer and allow for a greater permeability rate. The permeability of the shallow water table is approximately 2 feet per day, and for purposes of doing calculations, in DER Exhibit 2, a rate of 2 feet per day was used. Based on all available data, the soils and vegetation at the site should be more than capable of assimilating and fixing the nitrogen and phosphorus load from the effluent. There is little or no risk of contamination of water sources off-site, including Taylor Creek. The City of Okeechobee has agreed to obtain a $3,000,00c policy of pollution insurance protecting against pollution of drinking water wells resulting from construction of the proposed wastewater treatment facility, and the City has the authority to obtain the insurance. There is no reverter clause in a deed from Okeechobee County to the State of Florida that would effect the use of the proposed site as a wastewater treatment facility.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered granting a permit to the City of Okeechobee to construct the wastewater treatment facility as proposed.

The Issue Whether the Petitioner's request for variance should be granted.
Findings Of Fact Petitioner owns an undeveloped parcel of land in Palm Beach, County which is zoned industrial and on which he intends to construct a storage building to house and repair farm equipment. To provide sewage treatment at the site, Petitioner had designed an on site sewage disposal system and applied for a septic tank permit which was denied as was his variance request. The closest public sewage treatment plant to the property is over five miles from the site, and the closest private treatment is approximately three miles from the subject site. Petitioner has no easement to either site if capacity were available and if he chose to connect. However, the proof did not show capacity at either site. Although Petitioner does not intend to pollute the groundwater, the proof demonstrated that waste disposal into a septic tank from the maintenance and repair of farm equipment could result in the disposition of prohibited hazardous waste into the groundwater. Alternative methods of waste disposal are available which would properly dispose of the waste and, yet, protect the groundwater from contamination by hazardous waste. Such systems include certain aerobic treatment units and package plants. The monetary costs of these systems is greater than the septic tank proposal; however, the proof did not demonstrate that the cost was prohibitive or a hardship. Although the hardship, if any, caused by the denial of the variance was not caused by Petitioner, the proof failed to demonstrate lack of reasonable alternatives of waste disposal and the absence of adverse effect of the operation to the groundwater. Additionally, the proof failed to establish the ameliorating conditions of soil, water table or setback conditions although a survey of the property dated September 3, 1985, indicates that the subject parcel was not platted. Accordingly, the denial of the variance was proper.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that a final order be entered denying the variance.

Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant findings of fact are made: The Tamaron wastewater treatment facility (facility), located at 3800 Gatewood Drive, Sarasota, Florida, serves the Tamaron residential subdivision which was originally developed by U. S. Homes Corporation in 1976. The subdivision presently consists of 499 homes and was completely built out in the mid-1980's. The facility was originally owned and operated by U. S. Homes Corporation. Tamaron Utilities, a nonprofit entity comprised of the 499 homeowners, acquired the facility in November, 1987. At that time, the facility's existing operating permit was transferred to Tamaron Utilities. The facility is overseen by an elected board of volunteer homeowners. The Department is the agency of the State of Florida that is authorized to regulate domestic wastewater treatment and disposal facilities and permit their construction and operation. It is the successor agency to the Department of Environmental Regulation. By letter dated November 10, 1987, the Department notified Tamaron of the requirements of Chapter 87-303, Laws of Florida (Grizzle-Figg Amendment), which amended Section 403.086, Florida Statutes, and of the Department's intention to modify Tamaron's operating permit to incorporate a schedule of compliance with Section 403.086, Florida Statutes, as amended by Chapter 87-303, Laws of Florida. On August 23, 1988, an operating permit (D058-141783), which contained secondary water treatment requirements, was issued to the facility. Specific condition 7 of the permit required that the facility be in compliance with the Grizzle-Figg Amendment by October, 1990, or eliminate discharge to surface waters. On September 5, 1990, Tamaron filed an application with the Department to renew its domestic waste water treatment and disposal systems operation permit. Tamaron did not consider its facility as discharging waste into one of the specifically named water bodies set forth in the Grizzle-Figg Amendment or to "water tributary thereto" and thereby required to meet the advanced waste treatment criteria set forth in the Grizzle-Figg Amendment. However, in an abundance of caution, Tamaron proceeded to bring its facility into compliance with the advanced waste treatment criteria as set forth in the Grizzle-Figg Amendment. After numerous requests for additional information and several meetings between Tamaron and the Department, the Department issued its Notice of Permit Denial on April 9, 1991, asserting that Tamaron had not provided: (a) reasonable assurance that the requirements of Section 403.086(1)(c), Florida Statutes, mandating advanced waste treatment (AWT) before discharge to certain designated surface waters, would be met and; (b) reasonable assurance that the discharge to those certain designated surface waters would result in minimal negative impact as required by Section 403.086(5)(a), Florida Statutes. The facility continues to operate under its secondary treatment permit No. DO58-141783. The facility consists of a wastewater treatment plant designed for secondary treatment, with tertiary filtration. The design capacity of the facility is 155,000 gallons per day (0.155MGD) with actual flows of slightly over 100,000 gallons per day (0.100MGD+). Three percolation ponds surround the facility comprising the primary effluent disposal method for the facility. The Tamaron subdivision has a series of excavated surface water bodies (stormwater lakes), hydraulically connected, which eventually discharge at the northeast corner of the subdivision into Phillippi Creek. The direct path of surface water flow is from the subdivision's stormwater lakes to Phillippi Creek. These stormwater lakes are in multiple ownership. Under Department policy, stormwater systems permitted by the Department, its predecessor DER, or a water management district solely as stormwater treatment facilities under Chapter 17-25, Florida Administrative Code, are not considered "waters of the State". However, stormwater systems built prior to Chapter 17-25, Florida Administrative Code, permitting requirements, were considered "waters of the State" if they discharge more frequently than a twenty five year, twenty-four hour storm event. See Petitioner's exhibits 13 & 15. Tamaron's stormwater system was built prior to Chapter 17-25, Florida Administrative Code, permitting requirements, and was designed to discharge at a ten year, twenty-four hour storm event which is more frequent than a twenty five year, twenty-four hour storm event. Discharge of water into Phillippi Creek from the subdivision's stormwater lakes is fairly frequent; however, the volume of the discharge is low. Phillippi Creek is a natural surface water which eventually flows into Roberts Bay. Roberts Bay is a specifically named water body in the Grizzle-Figg Amendment (Section 403.086(1)(c), Florida Statutes). Since September, 1989, Tamaron has retained William Murchie, P.E. of AM Engineering, to evaluate the design and operation of the facility in order to comply with appropriate regulatory requirements. The facility provides biological treatment through a contact stabilization utilizing an activated sludge. This process typically provides high quality advanced secondary biological treatment. A chemical feed tank system utilizing ferrous sulfate was added to the facility several years ago to chemically precipitate out total phosphorus to meet the advanced waste treatment requirements. High-level disinfection is achieved in the large chlorine contact chamber and through two tertiary filters. At the design flow of 0.155MGD, the chlorine contact chamber provides nearly 80 minutes of contact time, while actual contact time for existing flows, not including time in filters, is calculated at 110 minutes. Upon leaving the chlorine contact chamber and the biological treatment components of the facility, the chlorinated effluent is directed through two tertiary filters to reduce the biochemical oxygen demand (BOD) and total suspended solids (TSS). After the tertiary filters, the effluent passes through the sample block where it is sampled for TSS, BOD and chlorine and is then piped sequentially into the first, second and third percolation ponds. The percolation ponds span two acres and provide residence time of 35 to 45 days, during which time the effluent is further biologically treated and nitrogen is reduced. From the percolation ponds, the effluent is pumped into a low pressure system which uniformly distributes effluent over two nitrogen reduction filters. The nitrogen reduction filters are located north of the plant and are immediately adjacent to one of the subdivision's stormwater lakes. The nitrogen reduction filters consist of deep sand beds covered with Bermuda grass to provide high nitrogen uptake. The irrigation of the two nitrogen reduction filters is alternated every half day. These nitrogen reduction systems were modified in October/November, 1990, by adding 3 to 3 1/2 feet of clean sand with a permeability rate of 28 feet per day, planting Bermuda grass, and installing an irrigation/distribution system. These filters replaced two sand pits with shallow layers of very coarse sand, after initial testing demonstrated the sand pits to be inadequate in removing nutrients consistent with statutory requirements. In January, 1992, an underdrain system utilizing perforated pipe was installed in the nitrogen reduction filters to create an aerobic zone and to provide a representative sample port after nutrient reduction in the filters. This sample port, used for the biweekly monitoring, consists of a single solid pipe, that collects effluent from the perforated pipes, with a tap to prevent discharge into the adjacent stormwater lake, except during sampling events. The biweekly sampling event results in effluent being discharged from the pipe for approximately 30 minutes to flush the pipe so as to get a proper sample. The underdrain sampling port at the nitrogen reduction filters replaced two earlier monitor wells between the nitrogen reduction filter and the stormwater pond, which proved ineffective because of their location. The perforated underdrains are situated in filter bed sand of medium grain size with a permeability rate 100 feet per day and located below 3 - 3 1/2 feet of clean sand with a permeability rate of 28 feet per day and above very permeable layers of sand, stone and coarse shell. (See Tamaron's exhibit 23 and Department's exhibit 14) The very permeable layers of sand, coarse shell, the perforated pipe and the single solid pipe are all located above the ground water table. Since the perforated pipe and sample port are both located above the ground water level and the surface of the adjacent stormwater lake, it is unlikely that the effluent sample taken from the sample port would be influenced by the ground water or a back flow of water from the adjacent stormwater lake. The coarse shell layer situated below the nitrogen reduction filters extends to the edge of the adjacent stormwater lake. Therefore, the effluent, other than the effluent trapped in the perforated pipe and carried to the sample port, that is irrigated onto the nitrogen reduction filters passes through the sand and into the coarse shell layer. The effluent is then transported laterally through the coarse shell layer to the underground edge of the adjacent stormwater lake where there is a subsurface discharge into the adjacent stormwater lake. Since the discharge to the stormwater lakes is primarily subsurface in nature, the logical compliance point to measure effluent parameters would be the underground sample port which collects the effluent prior to subsurface discharge into the stormwater lake. See Petitioner's exhibit 15. The direction of ground water flow at the facility is towards the north to the adjacent stormwater lakes as evidenced by the hydraulic gradient of the site determined using ground water table elevations. The location for sampling effluent from the facility for compliance with secondary standards was described in Specific Condition 5 of Tamaron's previous permit No. D058-141783 dated August 23, 1988. Specific Condition 5 states that the discharge from the chlorine contact chamber shall be sampled in accordance with Chapter 17-19, Florida Administrative Code, (now Chapter 17-601, Florida Administrative Code), for compliance with the stated secondary limits. The facility's tertiary filters are located after the chlorine contact chamber. Tamaron samples effluent for compliance with secondary standards (BOD,TSS, chlorine) at the sampling box after disinfection and tertiary filtration. Tertiary filtration is designed to achieve a more efficient removal of TSS and BOD. The resulting effluent is usually of higher quality than secondarily treated effluent. A secondary plant with tertiary filtration is referred to as an "advanced secondary treatment" plant. Data presented by Tamaron titled Tamaron 1991-1993 Data On FDER Permit Compliance (Tamaron's exhibit 17, page 1 of 2) shows reported values, sampled after tertiary filtration at the sample box, which suggest that secondary treatment parameters, including fecal coliform, are not being exceeded. The data actually shows a very high removal rate for the parameters sampled. The United States Environmental Protection Agency issued a National Pollutant Discharge Elimination System (NPDES) permit, number FL0042811, to Tamaron for the facility with an effective date of June 1, 1991, which authorized Tamaron to discharge from the facility to the receiving waters named Phillippi Creek to Roberts Bay in accordance with the effluent limitation, monitoring requirements and other conditions set forth in the permit. Since the facility was located in the Grizzle-Figg Amendment area of Florida certain changes were made from the draft permit to the final permit. Those changes appear in the Amendment To The Statement Of Basis At The Time Of Final Permit Issuance which is made a part of the final permit. The amendment provides for changes in Part I, Effluent Limitations and Monitoring Requirements. These changes, among other things, require that the Grizzle-Figg Amendment annual limits of 5 mg/l BOD, 5mg/l TSS, 3mg/l total nitrogen and 1mg/l total phosphorus be added to the effluent limits to adequately maintain water quality standards, and added monitoring requirements and measurement frequency regulations to give the basis for permit limits and conditions in accordance with Chapters 17-302, 17-600 and 17-601, Florida Administrative Code. Data presented by Tamaron titled Tamaron 1991-1993 Data On NPDES Permit Compliance (Tamaron's exhibit 17, page 2 of 2) show reported values sampled after nitrogen reduction filters which suggest that the maximum values for AWT parameters, including fecal coliform, are not being exceeded, particularly after January, 1992, when Tamaron began sampling effluent collected by the perforated underdrains at the sample port. Tamaron has been monitoring and reporting compliance under its final NPDES permit and providing copies to the Department. There was no evidence that Tamaron was ever in violation of its NPDES permit. Tamaron submitted documentation to the Department with its permit application that demonstrated high-level disinfection within the facility was being achieved. However, TSS was being sampled after the application of the disinfectant. Using this procedure, the facility continued to achieve high- level disinfection until the permit denial. After the permit denial, the facility resumed basic disinfection which was required under Tamaron's permit for secondary treatment. This same data indicates that there was compliance with the requirements for fecal coliform. The record is not clear as to the frequency and number of samples taken to provide the data for reporting compliance with the NPDES permit and the data presented in Petitioner's exhibit 17, page 2 of 2. However, there was no evidence, other than sampling for TSS after the disinfectant was added, that Tamaron was not complying with its NPDES Permit that required, among other things, that the monitoring requirements and measurement frequency of the Department's rules and regulations be followed by Tamaron. Tamaron has modified and upgraded the facility in order to achieve a treatment process which will produce effluent of a quality for discharge under the Grizzle-Figg Amendment. Tamaron has provided reasonable assurances, although not absolute assurance, that the facility can comply with the discharge permit requirements of Chapter 403, Florida Statutes, including Section 403.086, Florida Statutes, notwithstanding the testimony of Jay Thabaraj to the contrary concerning Tamaron's sampling technique and its method of obtaining high-level disinfection which can be addressed as a specific condition, if necessary. Studies conducted by the Tamaron's engineer included in Petitioner's exhibit 21 indicates that there was no adverse impact to the stormwater lakes from the facility's wastewater treatment and disposal system. Tamaron has provided reasonable assurances that the point of discharge is a reasonably access point, where such discharge results only in minimal negative impact.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Department enter a final order granting Tamaron an operating permit for its facility as secondary treatment facility. In the alternative, that the Department enter a final order granting Tamaron an operating permit for its facility that requires compliance with the advanced waste treatment criteria set forth in Section 403.086(4), Florida Statutes, that, in addition to any general or specific conditions that are normally required, contains specific conditions that: (a) contains specific instructions on sampling technique, sampling frequency and reporting as set forth in Rule 17- 740(1)(b)2., Florida Administrative Code, and (b) sets forth compliance with high-level disinfection, with a time limit for compliance, that accomplishes the intent of the rule, if not the strict letter of the rule, without total redesign of the facility.

Findings Of Fact Upon consideration of the oral and documentary evidence in the record, as well as the pleadings and joint prehearing stipulation, the following relevant facts are found: Cast-Crete owns and operates a concrete batch plant in Hillsborough County, Florida, and manufactures concrete products such as reinforced beams, lintels, seals and drainage structures on the property. The plant is located on the west side of State Road 579, 3/4 mile north of Interstate 4, Section 28, Township 28 South, Range 20 East. The concrete products are manufactured in various forms which are laid out over a large portion of Cast-Crete's property. Lubricating oils are utilized to facilitate the removal of the product from the confining forms. During this process some of the lubricating oil is spilled onto the ground. Also, cleaning solutions containing degreasers are utilized to wash the concrete trucks eight to ten times per day. This solution ends up on the ground. Aggregate limerock (crushed limestone) is used in the concrete formulation process and is stored in large piles on the property. In order to contain the dust, water is sprayed on the aggregate piles 24 hours a day. The wash water from the continuous process of wetting the aggregate, other waste water and some stormwater is channeled through the property and into a settling pond in the northwest corner of Cast-Crete's property. This pond discharges continuously off the property by way of a concrete flume into a county maintained ditch. Water in the ditch travels in a westerly direction approximately 200 to 300 yards before it passes under Black Dairy Road, where the watercourse deepens and widens. The ditch discharges into a marshy area which drains into Six Mile Creek and other water bodies. The pond at the northwest corner of Cast-Crete's property is equipped with a metal skimming device to remove oils and greases floating on the surface of the pond. Nevertheless, it is estimated that approximately 100 gallons of oil per year are discharged by Cast-Crete. Oil and grease in the outflow water is occasionally above 5 mg/L. Oil and grease layers have been observed on water at both Black Dairy Road and Six Mile Creek, probably resulting from road run- off. Approximately 90 percent of the water discharged from the property is a result of the wetting or washdown of the aggregate piles. The excess water which comes from the aggregate piles is laden with dissolved limestone, lime and limestone particles. This limestone dust raises the pH level of the water. Because of the continued wetting of the aggregate, water flows through the settling ponds and off of Cast-Crete's property at a rate of approximately 4.8 gallons per minute, or 7,200 gallons per day or 2.5 million gallons per year. During a rain event, the flow increases markedly. Except during times of heavy rainfall, water flowing from the respondent's property provides a thin stream of water in the drainage ditch approximately six inches wide and several inches deep. The pH of the wastewater from Cast-Crete's discharge flume is between 10 and 11 units. During high volume flows, the pH remains at or above 11 units. An increase of one unit of pH in the wastewater means that the wastewater has become 10 times more basic, since pH is measured on a logarithmic scale. The natural background of unaffected streams in the area of and in the same watershed as the Cast-Crete property is less than 8.5 units. Specific conductance or conductivity is the measure of free ions in the water. Typical conductivity readings from other water bodies in Hillsborough County range between 50 and 330 micromhos per centimeter. The specific conductance of Cast-Crete's wastewater ranges from 898 to 2000 micromhos per centimeter. This is due to the presence of calcium carbonate and calcium hydroxide in the water. Blue-green algae is the dominant plant species in the ditch between the Cast-Crete discharge flume and the first 150 meters of the ditch. A biological survey of the ditch system indicates that the diversity of species east of Black Dairy Road is low. This is attributable in part to the high pH of the wastewater. The low diversity can also be attributed to the fact that the County maintains the ditch by use of a dragline on an annual basis. Background samples from a site within one mile to the northwest of the Cast-Crete property were taken. The site (a stream passing under Williams Road) is an appropriate place to take background samples because the water there is unaffected by Cast-Crete's discharge or other man-induced conditions. The pH background sample ranged from 4.6 units to 5.1 units. The specific conductance background samples ranged from 70 to 100 micromhos per centimeter. Samples taken from a site potentially impacted by Cast-Crete's discharge showed a pH level of from 6.35 to 7.37 units and specific conductance of from 592 to 670 micromhos per centimeter. Cast-Crete discharges water from its concrete plants operation without a permit from the DER.
Recommendation Based upon the findings of fact and conclusions of law recited herein, it is RECOMMENDED that a Final Order be entered requiring respondent to submit a complete application for an industrial wastewater permit within thirty (30) days, and that, if it fails to do so, it cease discharging wastewater from its property until such time as an appropriately valid permit is issued by the DER.

Findings Of Fact By letter dated August 10, 1979, Indian River County (hereafter "County") submitted to the Department of Environmental Regulation (hereafter "Department" or "DER") applications for construction permits for the Gifford Area sewer treatment plant and collection improvements thereto, a domestic wastewater treatment and disposal system located in the County. (DER Exhibits Nos. 1 & 2). After receiving the permit applications submitted by the County, the Department's Orlando District Office requested additional information to determine whether reasonable assurances were provided that the facility would not discharge, emit or cause pollution in violation of Department standards. (Testimony of William Bostwick; testimony of Chancellor; DER Exhibits Nos. 3, 4, 5, 6, 7 & 8). The County, through its consulting engineers Sverdrup & Parcel and Associates, Inc., responded to the Department's requests for additional information. (DER Exhibits Nos. 3, 4, 5, 6, 7 & 8). The Department presented testimony of two professional engineers in its employ, Mr. William M. Bostwick and Mr. Gerald Chancellor, both of whom were accepted as expert witnesses in the field of sewage treatment technology and the processing and evaluation of permit applications for sewage treatment plants. Both witnesses testified that in their expert and professional opinion, based on their review of all plans, test results and other information submitted by the County, the applicant provided the Department with reasonable assurances that the proposed construction and operation of the sewage treatment facility and its collection system would not discharge, emit or cause pollution in violation of Department standards. (Testimony of Bostwick; testimony of Chancellor). The standards applicable to the subject construction permit applications involve (a) treatment level and (b) ambient standards of the receiving waters. The proposed system provides a minimum of ninety (90) percent treatment to incoming wastewaters. Because of the added features of surge tanks, gas chlorination, and dual blowers and motors, the ninety (90) percent minimum treatment was expected to be exceeded. (Testimony of Bostwick; testimony of Chancellor). The secondarily treated effluent from the proposed sewage treatment plant will be dispersed by spray irrigation. Because the effluent is expected to percolate to area groundwaters, the ambient groundwater standards of Section 17-3.101, Florida Administrative Code are applicable. The discharge from the facility will not cause any violation of the groundwater quality standards of the Florida Administrative Code. (Testimony of Bostwick; testimony of Chancellor; testimony of Aront). Although the design of the plant does not contemplate surfacewater discharge, if it did, it would meet the waste load allocation of Indian River County which permits discharge to surfacewaters. When the treated waste leaves the sprinkler head, it will meet secondary water treatment standards. (Testimony of Bostwick; testimony of Chancellor). In the course of evaluating a permit application for a wastewater treatment plant, the Department considers only Chapter 403, Florida Statutes, and its implementing rules and regulations and does not consider local issues relating to zoning, the propriety of expenditure of public funds or the like. (Testimony of Bostwick). There is presently no state standard regulating permissible levels of viruses in effluent discharged to either surface of groundwaters. Large numbers of viruses exist in the effluent discharged from spray irrigation treatment plants which operate at a ninety (90) percent treatment level. The viruses contained in the discharge remain viable as they percolate through the soil. The greatest concern exists when humans are in physical contact with such discharge. However, the present sewage treatment facility in its existing condition is a greater threat to public health than the proposed spray irrigation system. (Testimony of Dr. Welling, Petitioner's Exhibits Nos. 1, 2 & 3). Research concerning viral standards for effluent discharge is in an experimental stage. The Department is examining this question for possible future rule drafting. Neither the federal government nor any state, with the exception of Maryland, has adopted viral standards. (Testimony of Welling) The design of Use Gifford plant contemplates a series of perimeter monitoring wells through which groundwater samples can be attained and tested for compliance with groundwater standards end the presence of viruses. (Testimony of Aront) The plant will spray irrigate effluent at the rate of one (1) inch per week. Although surface run off is not expected, any that occurs due to heavy rains, etc., will be discharged into a perimeter ditch surrounding the plant. The plant design is formulated to retain effluent on site. (Testimony of Chancellor). There are four (4) different types of soil on the site with a water permeability of moderately rapid to very rapid. These soils have a percolation rate which makes the site suited for the intended purpose provided surface drainage is obtained. On a conservative basis the site could accept up to fourteen (14) inches of water per day or ninety-eight (98) inches per week. (Testimony of Connell; testimony of Eng; DER Exhibit No. 6). The parties stipulated prior to the hearing to the following: The project complies with local zoning laws; and The applicable provisions of law are Sections 403.086, 403.087, 403.088, Florida Statutes, and Rules 17-3.091, 17-4.03, 17-4.07 and 17-4.26, Florida Administrative Code.
Recommendation Upon consideration of the foregoing, it is RECOMMENDED: That the Department issue a construction permit to the County on condition that sample effluent from the monitoring wells on the subject facility be regularly analyzed for compliance with Department rules and the existence of infectious viruses.
