The Issue Whether SFP's revised application for a permit to construct a sewage treatment plant with percolation ponds should be granted or, for failure of SFP to give reasonable assurances that the plant will not cause pollution significantly degrading the waters of Gator Cove, be denied?
Findings Of Fact About 1,500 feet from Santa Fe Lake's Gator Cove, SFP proposes to build an extended aeration package sewage treatment plant to serve a "private club with restaurant and overnight accommodations," SFP's Exhibit No. l, to be built between the plant and the lake, on the western shore of Santa Fe Lake, just south of the strait or pass connecting Santa Fe Lake and Little Santa Fe Lake. The site proposed for the waste water treatment plant lies at approximately 177 or 178 feet above sea level, north of Earleton on county road N.E. 28 near State Road 200A, some three miles north of State Road 26, in unincorporated Alachua County, Section 33, Township 8 South, Range 22 East. SFP's Exhibit No. 1. Santa Fe Lake, also called Lake Santa Fe, and Little Santa Fe Lake, also called Little Lake Santa Fe, are designated outstanding Florida waters by rule. Rule 17-3.041(4)(i), Florida Administrative Code. Lake Santa Fe "is . . . the sixth largest non-eutrophic lake in the State of Florida . . . [and] the last remaining large non-eutrophic lake in Alachua County." (0.367). Recreation is a "beneficial use" of these waters. The Lakes Santa Fe are at an elevation of approximately 140 feet above sea level, and their level varies within a range of four feet. Input The proposed plant is to treat sewage generated by staff, by diners at a 150-seat restaurant, and by inhabitants of 150 lodge or motel rooms, comprising 100 distinct units. On the assumptions that 150 rooms could house 275 persons who would generate 75 gallons of sewage a day for a daily aggregate of 20,625 gallons, and that a 150-seat restaurant would generate 50 gallons of sewage per seat per day, full occupancy is projected to engender 28,125 gallons of sewage per day. This projection is based on unspecified "D.E.R. criteria; (5.35) which the evidence did not show to be unreasonable. Full occupancy is not foreseen except around the Fourth of July, Labor Day and on other special occasions. An annual average flow of between 15 and 20,000 or perhaps as low as 13,000 gallons per day is envisioned. (S.38) The proposed plant is sized at 30,000 gallons per day in order to treat the peak flow forecast and because package plants are designed in 5,000 gallon increments. Sluice-gate valves and baffling are to permit bypassing one or more 5,000 gallon aeration units so plant capacity can be matched to flow. The composition of the sewage would not be unusual for facilities of the kind planned. As far as the evidence showed, there are no plans for a laundry, as such, and "very little laundry" (S.37) is contemplated. The health department would require grease traps to be installed in any restaurant that is built. Gravity would collect sewage introduced into 2,000 feet of pipe connecting lodging, restaurant and a lift station planned (but not yet designed) for construction at a site downhill from the site proposed for the water treatment plant. All sewage reaching the proposed treatment plant would be pumped 3,000 feet from the lift station through a four-inch force main. Influent flow to the treatment plant could be calculated by timing how long the pump was in operation, since it would "pump a relatively constant rate of flow." (S.39) Treatment Wastewater entering the plant would go into aeration units where microorganisms would "convert and dispose of most of the incoming pollutants and organic matter." (S.40) The plant would employ "a bubbler process and not any kind of stirring-type motion . . . [so] there should be very little:; aerosol leaving the plant," (S.42) which is to be encircled by a solid fence. Electric air blowers equipped with mufflers would be the only significant source of noise at the proposed plant, which would ordinarily be unmanned. If one blower failed, the other could run the plant itself. A certified waste water treatment plant operator would be on site a half-hour each week day and for one hour each weekend. SFP has agreed to post a bond to guarantee maintenance of the plant for the six months' operation period a construction permit would authorize. (0.63) The proposed plant would not "create a lot of odor if it's properly maintained." Id. The specifications call for a connection for an emergency portable generator and require that such a generator be "provide[d] for this plant. . . ." (S. 43). The switch to emergency power would not be automatic, however. A settling process is to follow extended aeration, yielding a clear water effluent and sludge. Licensed haulers would truck the sludge elsewhere for disposal. One byproduct of extended aeration is nitrate, which might exceed 12 milligrams per liter of effluent, if not treated, so an anoxic denitrification section has been specified which would reduce nitrate concentrations to below 12 milligrams per liter, possibly to as low as 4 or 5 milligrams per liter. Before leaving the plant, water would be chlorinated with a chlorinator designed to use a powder, calcium hypochlorite, and to provide one half part per million chlorine residual in the effluent entering the percolation ponds. A spare chlorine pump is to be on site. The effluent would meet primary and secondary drinking water standards, would have 20 milligrams or less per liter of biochemical oxygen demand or, if more, no more than ten percent of the influent's biochemical oxygen demand, and total suspended solids would amount to 20 milligrams or less per liter. (5.294- 295). Half the phosphorous entering the plant would become part of the sludge and half would leave in the effluent. Something like ten milligrams per liter of phosphorous would remain in the effluent discharged from the plant into the percolation ponds. (5.202). Although technology for removing more phosphorous is available (S.298, 0.170-171), SFP does not propose to employ it. Allen flocculation treatment followed by filtration could reduce phosphorous in the effluent to .4 milligrams per liter, but this would increase the cost of building the treatment plant by 30 to 40 percent; and operational costs would probably increase, as well, since it would be necessary to dispose of more sludge. (0.170-172). SFP did agree to accept a permit condition requiring it to monitor phosphorous levels in groundwater adjacent to the proposed plant. (0.63). Land Application Three percolation ponds are planned with an aggregate area of 30,000 square feet. At capacity, the plant would be producing a gallon and a half of effluent a day for each square foot of pond bottom in use. The ponds are designed in hopes that any two of them could handle the output of effluent, even with the plant at full capacity, leaving the third free for maintenance. The percolation ponds would stand in the lakes' watershed, in an area "of minimal flooding, (S.30) albeit outside the 100-year flood plain. Santa Fe Lake, including Gator Cove, and Little Santa Fe Lake are fed by groundwater from the surficial aquifer. All effluent not percolating down to levels below the surficial aquifer or entering the atmosphere by evapotranspiration would reach the lake water one way or another sooner or later. If percolation through the soils underneath the percolation ponds can occur at the rate SFP's application assumes, effluent would not travel overland into Lake Santa Fe except under unusually rainy conditions, which would dilute the effluent. Whether the planned percolation ponds would function as intended during ordinary weather conditions was not clear from the evidence, however. In the event the ponds overflowed, which, on SFP's assumptions, could be expected to happen, if peak sewage flaw coincided with weather more severe than a 25-year rainfall, effluent augmented by rainwater would rise to 179.87 NGVD (S.34), then overflow a series of emergency weirs connecting the ponds, flow through an outfall ditch, drain into a depression west of the ponds, enter a grassed roadside ditch, and eventually reach Lake Santa Fe after about a half a mile or so of grass swales. (5.69). Sheet flow and flow through an ungrassed gulley in the direction of Gator Cove (0.154) are other possible routes by which overflowing waters might reach the lake. (0.263). Since the facilities the plant is designed to serve are recreational, wet weather would discourage full use of the facilities and therefore full use of the water treatment system. Effluent traveling over the surface into Gator Cove would wash over vegetation of various kinds. Plants, of course, do take up phosphorous, but they don't do it forever, and if you leave a plant system alone, it will come to a steady state in which there is no net storage of phosphorous in the plant material. (0.166) Whether by sheet flow or by traversing swales, overland flow would reach Gator Cove within hours. Effluent traveling through the surficial aquifer would not reach the lake for at least five years. (S.238-9). It could take as long as 45 years. (0.316). In the course of the effluent's subterranean passage, the soil would take up or adsorb phosphorous until its capacity to do so had been exhausted. In addition, interaction with certain chemicals found in the soil, primarily calcium, precipitates phosphorous dissolved in groundwater. As between adsorption and precipitation, the former is much more significant: "[W]ith a three-meter distance you can expect at least 70 to 80 percent removal of phosphorous just by a a[d] sorption alone." (0.21). Precipitated phosphorous does not return to solution, unless the soil chemistry changes. (0.19) Adsorption, however, is reversible, although not entirely, because of the "hysteresis phenomenon." (0.19) Eventually, a kind of dynamic equilibrium obtains to do with the binding of the phosphorous to soil constituents, binding or precipitation of phosphorous. At some point . all of the binding sites become saturated . [and] the amount of phosphorous leaving, into the lake really, will be equal to the amount of phosphorous going into the the system. When there is no more place to store the phosphorous in the ground, then the output is equal to the input and that is called the steady state. (0.161) Although precipitation of phosphorous would not reach steady state under "conditions that render the phosphorous-containing compound insolu[]ble," (0.168) these conditions were not shown to exist now "much less . . . on into perpetuity." Id. Spring Seep A third possible route by which the effluent might reach lake waters would begin with percolation through the sand, which is to be placed on grade and on top of which the percolation ponds are to be constructed. Underground, the effluent would move along the hydraulic gradient toward the lake unless an impeding geological formation (an aquiclude or aquitard) forced it above ground lakeward of the percolationi ponds. In this event, the effluent would emerge as a man-made spring and complete its trip to Gator Cove, or directly to the lake, overland. The evidence demonstrated that a spring seep of this kind was not unlikely. Relatively impermeable clayey soils occur in the vicinity. A more or less horizontal aquitard lies no deeper than four or five feet below the site proposed for the percolation ponds. Conditions short of an actual outcropping of clayey sand could cause effluent mounding underground to reach the surface. Nor did the evidence show that an actual intersection between horizontal aquitard and sloping ground surface was unlikely. Such a geological impediment in the effluent's path would almost surely give rise to a spring seep between the pond site and the lakes. In the case of the other percolation ponds in this part of the state that do not function properly, the problem is n [U] sually an impermeable layer much too close to the bottom of the pond," (S.179), according to Mr. Frey, manager of DER's Northeast District. Phosphorous in effluent travelling by such a mixed route would be subject to biological uptake as well as adsorption and precipitation, but again a "steady state" would eventually occur. On Dr. Bothcher's assumptions about the conductivity of the clayey sand (or sandy clay) lying underneath the topsoil, the effluent would accumulate as a mound of groundwater atop the clay unit, and seep to the surface in short order; and "after a matter of probably weeks and maybe months, it would be basically of the quality of the water inside of the percolation pond." (0.278). More Phosphorous in Gator Cove The total annual phosphorous load from all existing sources "to the lake" has been estimated at 2,942 kilograms. Assuming an average effluent flow of 17,000 gallons per day from the proposed plant, "the total phosphorous load [from the proposed plant] will be 235 kilograms per annum," (0.16), according to Dr. Pollman, called by SFP as an expert in aquatic chemistry. Even before any steady state condition was reached, 20.75 to 41.5 kilograms of phosphorous, or approximately one percent of the existing total, would reach the lake annually from the proposed plant, on the assumptions stated by Dr. Pollman at 0.22-23 (90 to 95 percent removal of phosphorous in the soils and average daily flow of 30,000 gallons). Santa Fe Lake is more than two miles across and two miles long, and Little Santa Fe Lake, which may be viewed as an arm of Santa Fe Lake, is itself sizeable, with a shoreline exceeding two miles. But Gator Cove is approximately 200 yards by 100 yards with an opening into Santa Fe Lake only some 50 to 75 yards wide. (0.154). On a site visit, Dr. Parks observed "luxuriant growth of submerged plants" (0.154), including hydrilla, in Gator Cove. If a one percent increase in phosphorous were diffused evenly throughout the more than eight square miles Santa Fe Lake covers, there is no reason to believe that it would effect measurable degradation of the quality of the water. Some nutrients are beneficial, and the purpose of classifying a lake is to maintain a healthy, well-balanced population of fish and wildlife. It's hard to see how 1.4 percent increase would lower the ambient quality. But . . . seepage into Gator Cove, which is a much more confined place [100 by 200 yardsj [would make it] quite probable that there would be a lowering of ambient water quality in the site . R] educed dispersion . . . in this cove would allow . . . phosphorous to build up. (0.156) Overland effluent flow to Gator Cove would increase concentrations of phosphorus there, with a consequent increase in the growth of aquatic plants, and the likely degradation of waters in the Cove, unless rapid and regular exchange of lake and cove waters dispersed the phosphorous widely, promptly upon its introduction Except for testimony that wind-driven waves sometimes stir up phosphorous laden sediments on the bottom, the record is silent on the movement of waters within and between Lake Santa Fe and Gator Cove. The record supports no inference that phosporous reaching Gator Cove would be dispersed without causing eutrophic conditions significantly degrading the water in the Cove. Neither does the record support the inference, however, that effluent moving underground into the lakes would enter Gator Cove. On this point, Dr. Bottcher testified: [T]he further away from the lake that you recharge water the further out under a lake that the water will be recharging into the lake; gives it a longer flow . . . it's going to migrate and come up somewhat out into the lake. (0.281-2) Phosphorous in the quantities the treatment plant would produce, if introduced "somewhat out into the lake" would probably not degrade water quality significantly, notwithstanding testimony to the contrary. (0.349, 354). Sands and Clays DER gave notice of its intent to deny SFP's original application because SFP proposed to place the pond bottoms approximately two and a half feet above an observed groundwater table. Placement in such proximity to groundwater raised questions about the capacity of the ground to accept the effluent. In its revised application, SFP proposes to place sand on the existing grade and construct percolation ponds on top of the sand. By elevating the pond bottoms, SFP would increase the distance between the observed groundwater table and pond bottoms to 5.2 feet. (S.256, 257). This perched water table, which is seasonal, is attributable to clayey sand or sandy clay underlying the site proposed for the percolation ponds. Between January 9, 1985, and January 17, 1985, "following a fairly dry antecedent period," (S.229) Douglas F. Smith, the professional consulting engineer SFP retained to prepare the engineering report submitted in support of SFP's permit applications, conducted six soil borings in the vicinity of the site proposed for the plant. One of the borings (TB 5) is in or on the edge of a proposed percolation pond and another (TB 4) is slightly to the north of the proposed pond site. Three (TB 1, 2 and 3) are east of the proposed pond site at distances ranging up to no more than 250 feet. The sixth is west of the proposed site in a natural depression. Mr. Smith conducted a seventh test boring under wetter conditions more than a year later a few feet north of TB 4. Finally, on September 5, 1986, during the interim between hearing days, Mr. Smith used a Shelby tube to obtain a soil sample four to six feet below grade midway between TB 4 and TB 5. 1/ The sites at which samples were taken are at ground elevations ranging from 173 to 178 feet above sea level. From the original borings and by resort to reference works, Mr. Smith reached certain general conclusions: The top four feet or so at the proposed pond site consists of silty sand, 17 percent silt and 83 percent quartz sand. This topsoil lies above a two-foot layer of clayey sand, 20 percent clay, 6 percent silt and 74 percent sand. Below the clayey sand lies a layer some eight feet thick of dense, silty sand, 23 percent silt, 7 percent clay and 70 percent sand, atop a one and one-half foot layer of clayey sand, separating loose, quartz sands going down 40 feet beneath the surface from what is above. These formations "are very heterogeneous, in the sense of the position and occurrence of the clay layers or the sandy layers . . .," (0.230) and all occur within the surficial aquifer. "There are layers of clay within it, and so perched water tables are rather common." (0.225). In March of 1986, the regional water table was some 17 feet down. SFP Exhibit 1B. Below the surficial aquifer lie the Hawthorne formation and, at a depth of 110 feet, the limestone of the Floridan aquifer. The soils above the Hawthorne formation are not consolidated. (S.254, 255). Conductivity Measurements The applicant offered no test results indicating the composition or conductivity of soils lying between the easternmost test boring and Gator Cove, some 1,200 feet distant. No tests were done to determine the conductivity of the deeper layer of clayey sand beneath the site proposed for the ponds. Tests of a sample of the topsoil in TB 7 indicated horizontal permeability of 38.7 feet per day and vertical permeability of six feet per day. On the basis of an earlier test of topsoil in TB 3, "hydraulic conductivity of the surface soils was measured to be 8.2 feet per day. . . ." SFP's Exhibit No. 1B. From this measurement, vertical hydraulic conductivity was conservatively estimated at .82 feet (9.84 inches) per day. Id. The design application rate, 2.41 inches per day, is approximately 25 percent of 9.84 inches per day. Id. The initial test done on a sample of the clayey sand, which lay beneath the topsoil at depths of 3.5 to 5.5 feet, indicated a permeability of 0.0001 feet per day. Thereafter, Mr. Smith did other testing and "made some general assumptions" (S. 235) and concluded that "an area-wide permeability of this clayey sand would be more on the order of 0.0144 feet per day." (S. 234). Still later a test of the sample taken during the hearing recess indicated hydraulic conductivity of 0.11 feet per day. SFP's Exhibit No. 10. The more than thousandfold increase in measured conductivity between the first laboratory analysis and the second is attributable in some degree to the different proportions of fines found in the two samples. The soil conductivity test results depend not only on the composition of the sample, but also on how wet the sample was before testing began. Vertical Conductivity Inferred On March 6, 1986, ground water was observed on the site about two and a half feet below the surface. SFP's expert, Mr. Smith, concluded that it was "essentially a 1.5 foot water table, perched water table over the clay." (0.422). There was, however, groundwater below, as well as above, the clay. On March 12, 1986, the water table at this point had fallen six inches. In the preceding month rainfall of 5.9 inches had been measured in the vicinity, after 5.1 inches had been measured in January of 1986, but in November and December of 1985 "there was a total of 0.6 inches of rainfall." (0.421). Later in the year, notwithstanding typically wet summer weather, no water table was measured at this point. From this Mr. Smith concluded that, once the clayey sand layer is wetted to the point of saturation, conductivity increases dramatically. If that were the case, a more or less steady stream of effluent could serve to keep the clayey sand wetted and percolation at design rates should not be a problem. But Dr. Bottcher, the hydrologist and soil physicist called as a witness for the Association, testified that the six- inch drop over six days could be attributed, in large part, to evapotranspiration. He rejected the hypothesis that the clayey sand's conductivity increased dramatically with saturation, since "the actual water table was observed . about three weeks after the very heavy rainfall had stopped" (0.290) and had probably been present for at least a month; and because the soil survey for Alachua County reports that perched water tables ordinarily persist for two months (0.227) in this type of soil. Certain soils' hydraulic conductivity does diminish with dessication, but such soils usually regain their accustomed conductivity within hours of rewetting. Dr. Bottcher rejected as unrealistically optimistic the assumption SFP's expert made about the conductivity of the clayey sand on grounds that "the conductivity that . . . [SFP] used, if you went out there you couldn't perch a water table for a month." (0.277). In these respects, Dr. Bottcher's testimony at hearing has been credited. In the opinion of the geologist who testified on behalf of the Association, Dr. Randazzo, a minimum of seven or eight additional augur borings in "definitive patterns to the northeast and to the northwest" (0.240) to depths of 15 to 20 feet, with measurements within each augur boring every two feet, are necessary to determine "how permeable the soils are and how fast the waters would move through them." (0.240). This testimony and the testimony of the soil physicist and others to the same general effect have been credited, and Mr. Smith's testimony that no further testing is indicated has been rejected. Wet Ground In the expert opinion of a geologist who testified at hearing, "it is reasonable to assume that saturation conditions of the surficial aquifer in this area can be achieved," (0.238) even without adding effluent from a wastewater treatment plant. The evidence that soils in the vicinity of the site have a limited capacity to percolate .water came not only from engineers and scientists. Charles S. Humphries, the owner of the property 150 feet from the proposed percolation site, "put a fence post line . . . every ten feet, and every ten feet [he] hit clay." (0.372). Three quarters of an inch of rain results in waters standing overnight in neighboring pastures. In parts of the same pastures, rain from a front moving through "will stay for a week or so." (0.373). It is apparent that the area cannot percolate all the rainfall it receives. This is the explanation for the gully leading down toward Gator Cove. Six-feet deep (0.377), "the gully is a result of natural surface runoff." (0.263).
Findings Of Fact Petitioner Ferncrest Utilities, Inc. owns and operates a sewage treatment plant at 3015 Southwest 54th Avenue, Fort Lauderdale, Florida. It presently services the needs of a population of about 2500 primarily located in three trailer parks, certain warehouses, a 153 room hotel, and several other business establishments. The plant was constructed and operated by a lessee of Petitioner's owners, but, in July 1979, Petitioner became the owner and operator of the facility. At that time, it was determined necessary to secure new operators and upgrade the plant equipment and method of process in order to properly service the existing and anticipated future number of customers in the area covered by a Public Service Commission franchise. Although the plant had been operating at a permitted capacity of 0.25 million gallons per day (MGD), Petitioner planned to expand the capacity to 0.60 MGD by modifying the aeration tank, and adding tertiary sand filters and equipment for clarification. Upon assuming control of the plant, Petitioner found that the 0.25 MGD permitted capacity had been exceeded by approximately 120,000 gallons per day for a number of years. Petitioner estimates that a population of 6,000 could be served under its new proposed design capacity. (Testimony of Forman, Exhibit 1) Pursuant to Petitioner's application for a construction permit, dated May 25, 1979, to modify the existing treatment plant, Respondent issued permit No. DC06-21789 on August 6, 1979. The permit specified that it was for construction of additional tank capacity for an existing 0.25 MGD wastewater treatment plant intended to approve effluent quality, and further stated that plant design capacity would remain at that figure. A subsequent letter from Respondent's subdistrict manager to Petitioner on January 15, 1980, stated that an evaluation of the quality of the surface waters receiving the plant discharge and the effect of such increased discharge would have to be made before processing a request for an increase in permitted flow. (Exhibit 7) On February 8, 1980, Respondent issued a temporary operating permit for Petitioner to temporarily operate a 0.25 MGD contact stabilization sewage treatment plant, including additional tank capacity and tertiary filtration. Specific conditions attached to the permit stated that it was issued to give the permittee a reasonable period of time to complete construction of the modification outlined in DER Permit DC06-21789 and for subsequent assessment of the effects of discharge on receiving waters. The conditions further required that the facility continue to achieve 90 percent removal of BOD5 and total suspended solids at all times with specified average daily discharges of such substances. Another condition required that the effluent from the plant be adequately chlorinated at all times so as to yield the minimum chlorine residual of 0.5 parts per million after a minimum contact period of 15 minutes. (Exhibit 8) Thereafter, on July 21, 1980, petitioner filed the instant application for an operation permit for the facility at a design capacity of 0.60 MGD. On October 7, 1980, Petitioner filed a certificate of completion of construction. By letter of December 16, 1980, Respondent's South Florida Subdistrict Manager advised Petitioner that the application for an operating permit had been denied for the reason that monitoring of the Class III receiving waters by the Broward County Environmental Quality Control Board indicated that the dissolved oxygen concentration was frequently below the minimum of 5 milligrams per liter required by Section 17-3.161(1), Florida Administrative Code, and that Petitioner's plant contributed to the substandard conditions in those waters. Petitioner thereafter requested a Section 120.57(1), F.S., hearing. (Exhibits 1-2, 4, 8) Petitioner's plant discharges into the North New River Canal through a six inch effluent pipe. The canal extends from Lake Okeechobee to the intracoastal waterway approximately five miles in distance from the point of discharge of Petitioner's plant. Monitoring of water quality in the canal for the past several years by the Broward County Environmental Quality Control Board shows that the dissolved oxygen concentrations at various sampling stations have ranged from below one part per million to in excess of five parts per million, depending upon the season of the year. However, at no station did the dissolved oxygen concentration reach an average of five parts per million. In addition, the tests also showed that BOD5 is generally low in the canal waters. (Testimony of Mazzella, Exhibits 1, 3, 5) Petitioner's modified plant is now capable of treating 0.60 MGD and meets current basic state requirements of 90 percent (secondary) removal of BOD and total suspended solids. In fact, the plant has tertiary treatment and can consistently operate at a level of 95 percent treatment. The data submitted by the applicant as to effluent water quality characteristics showed removal of 98 percent BOD, 97 percent suspended solids, 50 percent total nitrogen, and 25 percent total phosphorus with an average chlorine residual in the effluent of 0.2 parts per million. The dissolved oxygen level in the effluent has been established at 6.5 milligrams per liter. (Testimony of Hermesmeyer, Dodd, Exhibit 1) Respondent's district personnel took one 24-hour sample of the effluent from Petitioner's plant in March 1981 and determined that a concentrate of 14.6 milligrams per liter of ammonia was being discharged to receiving waters. Respondent therefore determined that the dissolved oxygen levels of the canal would be further degraded because approximately 48 to 50 parts per million of dissolved oxygen would be necessary to offset the effects of oxygen removal resulting from the ammonia discharge. Respondent further found that, although the effluent from the plant had 6.5 milligrams per liter of dissolved oxygen, the amounts of phosphorus and nitrogen being discharged could lead to algal blooms and consequent eventual eutrophication of its waters. Respondent's reviewing personnel therefore considers that there would be negative impacts upon the receiving waters if Petitioner discharged its prior licensed capacity of 250,000 gallons per day, and that a discharge of 600,000 gallons per day would double such impacts. Respondent's personnel therefore believes that although Petitioner's facility meets the basic secondary treatment requirements of Rule 17-6.01, Florida Administrative Code, it does not meet the water quality-based effluent limitation specified in Rule 17-6.10. In order to meet such requirements, it would be necessary to redesign the plant for more efficient removal of nutrients or to redirect the discharge. (Testimony of Mazzella) Other facilities adjacent to or near the North New River Canal discharge directly or indirectly into the canal waters and contribute to an unknown degree to the poor quality of the canal waters. Additionally, agricultural use of land produces stormwater runoff containing fertilizer residue into the canal in an unknown amount. A sewage treatment plant operates at optimum level of treatment when it discharges at about 50 percent of its treatment capacity. (Testimony of Mazzella) In 1983, Broward County will require Petitioner's plant to conform to state advanced waste treatment criteria which will provide for additional removal of nitrogen and phosphorus from effluent. To meet this requirement, Petitioner, plans to investigate the possibilities of utilizing a landlocked lake on its property near the treatment plant as a seepage pond. Although Petitioner's plant is identified in area regional plans to be diverted to the Hollywood wastewater treatment plant in the future, there is presently no target date for tying in to such a regional facility. (Testimony of Hermesmeyer, Exhibit 1)
Recommendation That Respondent issue a permit to Petitioner for the operation of its sewage treatment plant, with appropriate conditions as designed to protect the receiving waters.

Findings Of Fact The Petitioner is a special tax district created by special act of the Florida Legislature. Chapter 71-822, Laws of Florida. The district covers approximately seventy-two square miles in northern Palm Beach County and southern Martin County, Florida. Petitioner's purpose is to provide water, sewer, drainage and solid waste services within the district. In conformity with its powers, the Petitioner operates an advanced waste water treatment plant on property which it owns in northern Palm Beach County. Petitioner has secured appropriate permits from DER in order to construct and operate the treatment plant. The treatment plant is among the most advanced in southeastern Florida. It has a four million gallon daily capacity, which could be increased to an eight million gallon capacity. In treating waste water the plant utilizes filtration, disinfection, retention in a holding pond, and discharge into a remote off-site area. The present discharge system is to pump effluent from the retaining pond through a canal or drainage system to a recharge or discharge lake which is located approximately three miles north and west of the treatment plant. This is known as the western discharge system, and was installed at a cost of approximately one million dollars. Due to the large amounts of pumping activity, it is an expensive system to utilize. Through its instant application, the Petitioner is seeking a permit allowing it to discharge effluent on-site. Effluent would flow into percolation ponds that have already been constructed. Effluent would settle in the ponds, and eventually would percolate through the soil. This system would he less expensive to operate than the western discharge system. Petitioner is interested in experimenting with the amount of waste water treatment that can be obtained through action of vegetation in the percolation ponds upon the effluent. Such a natural system, if it operated effectively, could save the Petitioner additional money in treating waste water by reducing the need for chemical treatment. Petitioner's waste water treatment presently results in a discharge of effluent which within some parameters meets even drinking water standards. The Petitioner's system very effectively treats bio-chemical oxygen demand ("bod"), suspended solids, nitrogen, and phosphorus in the effluent. Reports have been submitted by the Petitioner to DER which indicate that the system does not meet DER's standards for advanced waste water treatment. Samples upon which these reports were based were taken at a point in the system before the effluent was subjected to the action of the retention pond and the subsequent bumping into the western discharge system. Samples taken beyond the retention pond indicate that DER's standards are met for "bed", suspended solids, total nitrogen, and total phosphorus. The Intervenor owns property adjacent to the Petitioner's waste water treatment plant. The Intervenor operates a well field and drinking water treatment plant on the property, and provides drinking water to residents of the Town of Jupiter and surrounding communities from the well field. The Intervenor acquired its treatment plant, and surrounding well fields from a private utility company. The Petitioner was aware of the well field when it purchased the property upon which it presently operates its waste water treatment plant. While the Petitioner's plant adequately treats waste water in terms of "bod", suspended solids, total nitrogen, and total phosphorus it does not treat the waste water for heavy metals, pesticides, or viruses. These are common elements found in waste water effluent in the south Florida area. The Petitioner's proposal is to discharge its effluent into on-site ponds. The effluent would then percolate into the ground. The retention ponds are located at a distance from 1200 to 1600 feet from the nearest of the Intervenor's wells. Water which percolates from these ponds would flow directly toward the wells, and would eventually find its way into the wells. The flow from the retention ponds to the wells would be increased due to the draw-down effect that the wells have on the surrounding water table. As water is drawn from the wells, the adjoining water table becomes depressed in the area of the wells, and water from the surrounding area flows more rapidly into the area of the wells. Heavy metals will not be filtered out as a result of retention or percolation. Heavy metals in the effluent would eventually find their way into the Intervenor's well fields. Estimates as to the amount of time that it would take for water from the percolation ponds to reach the wells varied from four months to six years. The longer estimate appears the more reasonable; however, the evidence is conclusive that eventually waters from the percolation ponds would reach the wells, and that heavy metals in the water would not be filtered out. The Petitioner proposes to obviate any problems with heavy metals reaching the well fields by operating testing wells between the percolation ponds and the well fields. If any heavy metals were detected in the ground water, Petitioner would again use the western discharge system rather than the percolation ponds. While this would prevent increased contamination of the wells, contamination that had already reached the test wells would reach the Intervenor's wells. It was suggested that the percolation ponds could be drawn down in order to reverse the flow of ground water back into the percolation ponds, thence to be pumped through the western discharge system. In order to accomplish this, however, the percolation ponds would have to be more than forty feet deep, which they are not. The effect of heavy metals intruding into the Intervenor's water supply could be to increase the cost of treatment, or to render the wells unfit for use. Uncontaminated drinking water supplies are rare in the northern Palm Beach County area, and the expense of finding a new water supply is difficult to calculate.
The Issue Schofield Corporation of Orlando has applied to the Department of Environmental Regulation for a permit to construct and operate a Class III trash/yard trash landfill in Orange County, Florida. The issues are whether the applicant is entitled to the permit and, if so, what conditions should attach. Also at issue is Schofield Corporation's motion for attorney's fees and costs, pursuant to Section 403.412(2)(f), F.S.
Findings Of Fact The applicant, Schofield Corporation of Orlando (Schofield), owns the proposed landfill site and existing permits for the site. The proposed site is located in West Orange County, southwest of the intersection of State Road 545 and Schofield Road on the west half of the northwest quarter of section 32, township 23 south, range 27 east, comprising approximately sixty acres within a larger eighty-acre parcel. In some undetermined distant past the site was cultivated in citrus. It is currently being excavated as a borrow pit. The materials proposed to be placed in the landfill include trash, yard trash, construction and demolition debris and clean debris, as defined in DER Rule 17-701.020, F.A.C. The northern half of the site is flat and will be used first for the composting operation. The southern excavated portion of the site will receive the permitted fill material until it is flattened. Then, the two functions will alternate; the composting will occur on the south, and the north end will be excavated to receive fill. The proposed facility will be operated by Chambers Corporation, a nationally recognized waste management company with approximately 20 years of experience in solid waste management. The landfill site will be completely fenced, with a gate entrance mid-site between the landfill and compost area. The gate will be locked when the facility is not in operation, and will be patrolled by security personnel 24 hours a day. "Spotters", or inspectors will be employed to examine incoming waste loads at the gate, from a high gantry, and at the place where the waste is deposited. The loads will be monitored by a television camera, and all haulers will be under contract. The landfill will not accept loads from trucks coming off the road looking for a place to dump. Receptacles will be maintained on site to receive errant non-permitted waste that is found in a load, and that waste will be properly disposed of elsewhere. Schofield has several permits related to its proposed operation. These include a type III landfill permit from Orange County, a compost facility permit from DER, a general construction and demolition debris landfill permit from DER, a surface water management permit from the South Florida Water Management District, and a permit to excavate or mine from the Florida Department of Natural Resources. Schofield also has a contract to receive yard waste from Orange County. The initial term of contract requires at least ten percent of the yard waste to be composted or recycled, with the percentage amount to be renegotiated in subsequent contract renewals. In the hierarchy of landfills, DER considers Class III the least environmentally sensitive. Problems with unauthorized waste and with water quality occur more frequently with Class I landfills, defined as accommodating more than twenty tons a day of residential garbage. In this case DER has proposed to grant Schofield its Class III permit without the requirement of a bottom liner or a leachate or gas control system because of the nature of the waste that will be accepted and because of the rigorous controls, described above, to avoid receiving unauthorized or hazardous waste. The Petitioners are an individual and a homeowners' association representing a residential area approximately a half mile south of the proposed site. Petitioners contend that the applicant's data is insufficient to provide reasonable assurances that water quality standards will not be violated. Petitioners contend that the landfill, if approved, should be required to have a liner to prevent leachate from polluting the groundwater. They further contend that the groundwater monitoring plan submitted by the applicant is inadequate to detect vertical movement of contaminated leachate into the Floridan aquifer, a major source of water supply in Orange County. Hydrogeology The site of the proposed landfill is within a high recharge area. Water percolates rapidly though the soil, moving downward into the aquifer, and laterally off site. The site is considered Karst terrain, underlined with limerock. There is evidence of relic sinkholes, thousands of years old, but there is a low probability of future open sinkhole development. The geology in the area of the site provides adequate structural support for the proposed facility. An aquifer is generally defined as a unit of material which contains water and can give up a sufficient amount of yield to provide some productive flow for pumpage. Below the site there are two aquifers: the shallow water table, or surficial aquifer, containing clean well-drained fine sands, about 70 feet down; and the Floridan, primarily limestone, encountered at a depth of approximately 115 feet. The two are separated by a confining layer of less permeable sands and clay. Flow in the Floridan at the site is primarily from the west to east. Flow in the surficial is also generally from west to east, but the Petitioners theorize, and have presented competent supporting evidence, that there are fissures in the confining layer, allowing some internal drainage within the site, causing surficial water to flow vertically into the Floridan, rather than laterally off-site in an eastward direction. Based on recent data taken from two piezometers installed near the middle of the site, the applicant's hydrogeologist, James Golden, concedes that "mounding" exists along the eastern boundary of the site, reflecting some flow westerly back into the interior of the site. Petitioners' theory regarding internal draining of the site is based in part on data as to groundwater elevation. Groundwater elevation or high groundwater table is the elevation at which water stands on a continuous surface under the site. Jammal and Associates is a consultant firm which has done field studies of this and neighboring sites in the past, for various purposes. Some open bore readings taken by Jammal and Associates in a 1983 study for the Orange County Rapid Infiltration Basin project indicate groundwater table levels on site up to 126 feet, National Geodetic Vertical Data (NGVD). Open bore readings are less reliable than cased hole readings; due to collapses within the hole, artificially high readings are sometimes obtained. Data from the applicant's consultants reveals groundwater tables at 96-98 NGVD. This data was most recently obtained in December 1991 from sealed and surveyed piezometer casings, but not from the area of the site where Jammal's higher readings were obtained. Although it may be conjectured that Jammal's high readings are anomalous, additional sealed borings need to be obtained before the anomaly is confirmed. Groundwater elevations are significant also to determine the depth to which the landfill may be excavated. Based on its December 1991 readings, obtained after the application for permit was filed, the applicant agreed to raise the proposed bottom of the landfill to approximately five feet above the level of the estimated high (wet weather) groundwater table in the area. Water Quality and Monitoring Specific conditions of the proposed permit include DER's requirements that Class GII water quality standards be met at the boundary of the zone of discharge, in accordance with Rule 17-3, F.A.C. The zone of discharge for this facility is a three-dimensional volume defined in the vertical plane as the top of the ground to the base of the most surficial aquifer, and horizontally 100 feet from the edge of the waste-filled area, or the property boundary, whichever is less. The groundwater monitoring plan proposed by the applicant includes one upstream monitoring well on the west side of the site and five wells along the east side of the site, with an additional well at the south, between the project and the Petitioners' residential area. The wells extend down into the upper zone of the surficial aquifer, but not into the deeper limestone Floridan. The downstream wells should detect any contamination in the surficial aquifer flowing from west to east at the zone of discharge. However, they will not pick up contamination draining internally within the site and into the Floridan. Such contamination is possible, even though leachate from Class III- type wastes is expected to be relatively benign. Volatile organic carbons (VOCs) have not typically been a problem in Class III landfills, unless those landfills were previously operated as Class I sites. Secondary drinking water standards for certain metals have been violated at some Class III sites, but such violations are often related to the problem of sampling newly-installed wells. From DER records, Petitioners presented evidence of consistent drinking water quality standard violations in Class III landfills. That such violations can occur in Class III landfills is clearly established. It is not so clear that such violations will occur in this facility, given the proposed controls on load content. However, even acceptable materials will not avoid the production of leachate or gas. Within demolition waste there are chemically bound components which are inseparable, for example, creosote and other preservatives, glues, paints, resins, varnishes and stains. The lignin, tannins and volatile organic acids which are produced when wood decomposes alter the pH of the groundwater. As the water becomes more acidic, heavy metals that were typically bound up in the waste or in the soil, are released in soluble form and travel with the water. The decomposition process occurring in the construction and demolition waste is enhanced by the addition of yard trash which becomes the food source for the biodegradation. Summary of Findings and Proposed Permit Conditions If, as applicant suggests, all groundwater moves primarily from west to east within the site, given the proposed operational controls and the proposed monitoring plan, reasonable assurances have been provided that water quality standards will not be violated beyond the zone of discharge. That is, any contamination likely to occur will be contained within the surficial aquifer and within the 100 feet or property line horizontal boundary. Transmissivity of the surficial aquifer is low enough to allow mixing of the leachate before it reaches the zone of discharge. The Petitioners, however, have presented credible evidence sufficient to question the groundwater flow premise and sufficient to require additional conditions on the permit. If leachate reaches the Floridan through fissures in the confining layer, it will move rapidly off site. In its proposed recommended order DER has suggested additional permit conditions and in its adoption of the proposed recommended order, the applicant has accepted those additional permit conditions. Those permit conditions recognize the fact that data presently provided by the applicant is insufficient to overcome the evidence by Petitioners as to the hydrogeological characteristics of the site with the possibility of internal drainage and vertical intrusion of contaminated water into the Floridan aquifer. The proposed recommended order provides this finding: ...that the ground water monitoring plan as proposed in this proceeding is adequate, provided that there be added to the permit conditions that the permittee conduct appropriate water table testing with cased piezometers during the next wet season to determine whether ground water flow is internal within the site and therefore not intercepted by the present ground water monitoring wells. The permittee shall consult with DER and get approval for the location and construction of these wells prior to their installation. The results shall be immediately submitted to the DER. The ground water monitoring requirements should be modified if necessary at that time pursuant to Rule 17-28.700(5) to assure proper monitoring at this site. (DER proposed Recommended Order, p. 17) The ground water monitoring plan modification suggested by DER is that deeper monitoring wells, into the Floridan aquifer, be required if the additional testing reveals the likelihood of internal on-site ground water drainage. These conditions are still inadequate since they lack specificity with regard to the extent of testing, the location and construction of the wells, and the amendments to the monitoring program to be required if internal drainage is confirmed. Moreover, the proposed conditions fail to address the possibility that the permit should require a liner for the landfill if the data to be obtained reveals the likelihood that contaminates will penetrate into the groundwater of the Floridan. Monitoring programs, however effective, only predict or detect problems; they do not remediate them. Groundwater contamination by landfills is not quickly and easily reversed. Unlike discharges from other facilities such as spray application or deep well injection, the leachate from a landfill is not "turned off". Without the additional data which all parties agree is needed, it is impossible to determine what additional conditions, if any, should be required or what amendments, if any, need to be made to the applicant's proposed monitoring plan.

Findings Of Fact The permit Applicant and Co-Respondent, Florida Medical Facilities, Inc. is the owner and developer of a 60-acre tract of land upon which it has constructed a hospital and will construct various attendant laboratories, medical offices and the like. Additionally, the Applicant is the owner of approximately five acres of land adjacent to its original 60-acre site which lies on Morningside Drive in Englewood, Sarasota County, Florida. The Applicant proposes to construct and operate the wastewater treatment plant on that 5-acre parcel. The Applicant proposes to construct an extended aeration wastewater treatment plant and effluent disposal drain field system which will accommodate and dispose of all wastewater effluent on the site by the absorption bed, land application method. The proposed sewage treatment plant will have an average daily design flow capacity of 50,000 gallons per day. The anticipated peak flow of the treatment plant will be 60,000 gallons per day. The plant will generate and dispose of approximately 900 gallons of waste sludge on a daily basis. The facility would employ dual drain fields, use of which would be rotated on a weekly basis. The proposed average hydraulic loading rate would be 3.21 inches per day or two gallons per day, per square foot of drain field. The proposed facility will serve a 100-bed community hospital, assorted medical offices, a diagnostic laboratory and a 75-bed nursing home. The permit applicant has agreed and stipulated that chemical, nuclear and other hazardous and noxious waste materials, blood, body parts, medicines, and drugs will not be introduced into the sewage treatment system plant or drain fields. The Applicant (FMF) originally proposed to dispose of sewage effluent emanating from its hospital and other facilities by transmission of it through force-mains to existing public wastewater systems, one of which is in Charlotte County and the other in Sarasota County. After exploring these possibilities, these alternatives proved to be either too expensive or to involve transmission of effluent over too great a distance to make these options feasible. Sarasota County has a local pollution control program approved by the DER, pursuant to Section 403.182, Florida Statutes. Under this program the Sarasota Environmental Service Department reviews domestic wastewater treatment facility permit applications pending before the DER and makes recommendations on their disposition. The county's ordinance concerning such facilities is equivalent to the DER standards, except in some respects it is stricter Mr. Russell Klier of the county environmental services department established that the proposed project as planned and designed, will comply with county ordinances regarding wastewater treatment plants. Indeed, it was established through Mr. Klier's testimony, that the proposed project has more redundancy and reliability safeguards than any other such project presently operating in Sarasota County. The proposed sewage treatment plant and disposal system is designed to attain the secondary level of treatment required by Chapter 17-6.060, Florida Administrative Code. The effluent disposal system will provide for disposal of effluent in an absorption field system as envisioned by Chapter 17-6.040(4)(M), Florida Administrative Code and the Department's "Land Application Manual," incorporated by reference in that rule. The system, as proposed, will have the additional safeguards required by the "Land Application Manual" in order to attain "Class I reliability." The hospital, which is the initial facility to be constructed on the 60-acre site, is largely completed, and is being served by a temporary "package" sewage treatment plant until the permit application is resolved. The package sewage treatment plant, as well as the proposed plant and drain field land application system will only serve the medical center complex. All on-site stormwater and surface water run-off from both the 60-acre original medical center site, as well as the 5- acre proposed sewage treatment plant and disposal site, will be managed by directing stormwater and surface water run-off to holding ponds to be constructed and maintained on the original 60-acre site. Steven Houghton was accepted as an expert engineering witness. It was thus established that the system as designed will meet all water quality parameters regulated and enforced by the DER and Sarasota County in terms of the quality of the effluent generated by the plant and disposal system for disposal by land application. In this connection, he established that no nuclear, infectious, toxic or noxious waste will be processed by the system or introduced into the system nothing other than domestic-type sewage will be treated, processed and disposed of by the proposed system. Mr. Houghton acknowledged that the project will be located in an historically flood-prone vicinity, but that will not affect the quality or effectiveness of the operation of the plant nor the safe disposal of the resulting effluent. In that regard, the Applicant will place fill at the drain field site so as to provide a more effective soil percolation condition than that presently existing in the soils at the drain field site. Additionally, the Applicant will provide a sewage storage tank to provide extra reliability and avoidance of pollution caused by sewage overflows in the event of any excessive sewage flows into the plant, and as a safeguard against disposing of insufficiently treated effluent during periods of high rain and high surface or ground water conditions. Additionally, the system will be constructed and operated with sufficient redundancy of electrical and mechanical components so as to provide auxiliary capacity throughout the system, allowing it to operate efficiently 24 hours a day and to continue to provide treatment and disposal of the effluent in accordance with secondary treatment and Class I reliability standards, even during periods of mechanical or electrical outages. Petitioner Mary Wagoner owns and resides on acreage generally south and adjacent to the proposed project site. Mrs. Wagoner uses a potable water well in the shallow aquifer with a depth of approximately 35 feet. Mrs. Wagoner's well has recently been tested and at this time provides good, safe, potable water which she uses both for drinking, cooking, domestic usage, as well as water for her livestock. Mrs. Wagoner's well is less than 500 feet from the proposed "wetted area" of the drain field land application disposal site. Mr. Edward Snipes was accepted and testified as an expert witness in the areas of engineering and wastewater engineering on behalf of the Department. He corroborated Mr. Houghton's testimony in establishing that the project would meet the Department's standards for water quality and Class I reliability in large part. It was shown that the project will not likely have harmful effects on the Petitioners' water wells. Mr. Snipes established that the Department's "Land Application Manual" embodied in Rule 17-6.04(4)(Q), Florida Administrative Code requires a buffer zone of only 100 feet, instead of 500C feet, from the wetted area of the sewage effluent disposal site, due to the type of system and level of treatment proposed. That is, the system would provide secondary treatment, with additional safety measures incorporated in the design and operation so as to achieve Class I reliability. This Class I reliability standard includes a sufficiently high rate of disinfection so as to allow unrestricted public access to the site, and thus would meet the most stringent Class I reliability standards extant in Rule 17- 6.040(4)(M), Florida Administrative Code. This permits a reduced buffer zone between the wetted area of the drain field and any adjacent, shallow-water wells. Thus, the buffer zone would, in the case of this plant, be allowably reduced from 500 feet to 100 feet. In only one respect, was any doubt cast by Petitioner's testimony and evidence on the showing of reasonable assurances that all Department water quality and wastewater treatment standards will be met. That doubt concerns the distance from the bottom of the drain field to the water table elevation at the drain field site, as that relates to the ability of the system to continue to treat and dispose of effluent within appropriate standards in this admittedly flood-prone area, as that problem would in turn relate to potential contamination of ground water in the area, especially in times of high rainfall and high ground water levels. In that connection, Petitioner Wagoner offered Herman Weinberg as an expert witness in civil engineering and he was accepted. Mr. Weinberg acknowledged that he was not a soil engineer and acknowledged that the Department or its witnesses were more knowledgeable about wastewater regulation, treatment and disposal methods than he. He opined, however, that the plant may not be able to reach Class I reliability due to its location in a flood-prone area. He fears that insufficient soil testing and water quality testing had been done prior to the filing of the permit application. and prior to the ultimate construction of the project, if that is to be the case. Section 17-6.040(4) (M), Florida Administrative Code, adopts by reference the United States Environmental Protection Agency design criteria for mechanical, electrical and fluid system and component reliability manual. That manual sets forth certain minimum standards for Class I reliability sewage treatment and disposal plants and systems. In this regard, the rule in that manual establishes that wastewater treatment works include holding ponds and basins and other structures of the disposal system. It provides that all treatment works, structures, as well as electrical and mechanical equipment, shall be protected from physical damage by flooding of a magnitude occurring on the average of once in a hundred years, the so- called "100-year flood." In this connection, it was established through witness Weinberg's testimony as well as that of Mr. Houghton, the Applicant/Respondent's witness, that the 100-year flood plan elevation on and around the subject site is 12 feet above mean sea level. The top of the proposed drain field would be located at 12.33 feet elevation. The bottom of the drain field would be at 10.33 feet elevation. The water table level established by witness Houghton as a result of his survey and calculations, is at 8.33 feet elevation. The Department of Environmental Regulation, in its "Land Application Manual," which provides criteria for sewage plant and disposal system construction and operation, requires a 36-inch minimum separation between the bottom of a drain field and the design water table level. Thus, the legally operative Class I reliability standards, incorporated in the above-referenced rule and manuals, and which the Applicant and the Department agree is the level of reliability required, given the conditions and the proximity of Petitioner's well, can only be met if the drain field disposal system is at this required elevation of 36 inches above the design water table level. Affirmative, reasonable assurances that this safeguard will be incorporated in the subject system are necessary in view of the fact that Petitioner Wagoner's potable water well is clearly less than 500 feet from the wetted area of the drain field site. In this connection, the Applicant/Respondent has proposed placing fill soil of a suitable type for adequate percolation and land application treatment of the effluent on the drain field site, however, it has not been established that this will be done to such an extent as to raise the elevation of the drain field sufficiently so that the bottom of the drain field is a minimum of 36 inches above the design water table. The installation of an adequate depth of fill soil of a suitable percolation characteristic must therefore be a condition on the issuance of the permit. Further, in that regard, the Applicant/Respondent's soil test and calculation of tile ground water level or "design water table," occurred in January and February of 1985, at a time when the southwest region of Florida was in a drought or dry condition, such that the water level or ground water table at normal rainfall conditions would likely be at a higher elevation. Thus, a grant of this permit must be conditioned upon the installation of sufficient, appropriate quality fill soil to ensure that the minimum 36-inch separation between the drain field bottom and the water table is maintained during normal water table or rainfall conditions. If this measure is not taken, given the 2-foot separation between the drain field, as designed, and the water table, the oxygen transferring capacity of the soil beneath the drain field may not be sufficient to satisfy the oxygen demand required for consistently adequate treatment and safe disposal of the sewage effluent. Additionally, in this same context, Chapter 1 of the DER Land Application Manual at Section 1.3, requires that sufficient storage capacity exist on-site to ensure retention of sewage effluent during conditions which preclude land application, such as high ground water conditions or flooding conditions. This capacity should be equivalent to three days maximum daily flow at the design capacity of the plant, or in this case, 180,000 gallons. Although the Applicant, by its plans and specifications in evidence, has assured that a sewage effluent storage tank will be constructed and operated, it has failed to establish that sufficient storage capacity will be incorporated to assure the retention of 180,000 gallons of effluent. Any grant of the permit application should be conditioned upon such an assurance. Finally, in connection with the above-mentioned condition concerning installation of sufficient, appropriate soil filling to allow for a minimum 36-inch amount of unsaturated soil beneath the drain field, that addition of fill should also be of a sufficient type and amount to ensure that the Applicant's proposed rotation or "resting" of drain fields for 7-day periods will be adequate to ensure that the subject amount of soil is unsaturated before re-use of either of the two drain fields. There should be incorporated in these conditions, upon a grant of the permit, the requirement that the Department monitor construction of the proposed facility to ensure that the above conditions are adequately met, in view of the low-lying terrain at the drain field site and the flood-prone condition of that locality. Petitioner Mary Nygaard testified on behalf of herself and her husband, Lyle A. Nygaard. Mrs. Nygaard complains of feared pollution of her shallow-water potable well which she maintains is within 500 feet of the drain field and sewage plant site. Mr. Nygeard established that the well is 187.1 feet from the Petitioner's southern property boundary, but acknowledged that no survey has been done delineating the distance to the proposed wetted area of the drain field. It was not otherwise proven how far the Nygaard's potable well is from the wetted area of the proposed drain field where the effluent will be disposed of. Various easements and roadways lie between the Nygaard's well and the wetted area of the proposed drain field site with indeterminate dimensions, thus it was not proven what distance exists between the Nygaard's well and the drain field site other than that it exceeds 187.1 feet.
Recommendation Having considered the foregoing Findings of Fact and Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is, therefore RECOMMENDED: That the application of Florida Medical Facilities for a permit authorizing construction of an extended aeration, wastewater treatment plant and disposal system to serve only the Englewood Hospital and Medical Center project in Englewood, Sarasota County, Florida, referenced above be GRANTED, provided that the above-delineated conditions upon a grant of the permit are complied with.

Findings Of Fact Trans/Circuits is a manufacturer of electronic printed circuit boards located at 210 Newman Way, Lake Park, Florida. Trans/Circuits' manufacturing operation involves the deposition of copper on plastic boards and the use of a lead or tin etch resist in order to create an electrically conducting circuit board. In the course of the manufacturing process, rinsewaters are used which become contaminated with copper and lead from the manufacturing process. These rinsewaters undergo chemical treatment to remove the metals and other contaminants, and are then discharged into an unlined percolation pond located behind Trans/Circuits' facility. About 36,000 gallons of effluent are discharged into the pond every day. The percolation pond discharges into ground water underlying Trans/Circuits' facility which groundwaters contain less than 3000 milligrams per liter (mg/l) of total dissolved solids. Trans/Circuits uses a Havviland brand wastewater treatment system. The system at present does not provide treatment sufficient to remove copper, fluoride, and lead from the wastewater effluent in compliance with the DER class G-II groundwater standards for these metals, i.e., 1.0 mg/l of copper, 1.5 mg/l of fluoride, and .05 mg/l of lead. Trans/Circuits has exceeded the effluent limitations for copper and lead at almost all times since at least June 1984. Trans/Circuits is not likely to comply with those standards for at least six months, by Trans/Circuits' own admission. The Operating Permit Application, Case No. 83-3676 Trans/Circuits requested a hearing to contest the DER Notice of Intent to Deny the application for an operating permit. The burden of proof and burden of going forward is therefore on Trans/Circuits to show that it is entitled to issuance of the operating permit. In this regard, Trans/Circuits did not introduce into the case any evidence relating to the operating permit application and did not introduce the application, itself. Further, Trans/Circuits did not present any evidence that its installation will abate or prevent pollution, or that it can provide reasonable assurances that the system which it seeks to operate will not discharge, emit or cause pollution. The Trans/Circuits facility has never been in compliance with DER standards and cannot provide assurances that it will be in compliance at anytime in the foreseeable future. Further Trans/Circuits has been operating without an operating permit at least since October 1983. The Month-to-Month Authorization, Case No. 84-0191 On September 17, 1982, DER issued a Notice of Violation and Orders for Corrective Action (NOV) to Trans/Circuits. The NOV alleged that Trans/Circuits violated provisions of Chapter 403, Florida Statutes, and DER rules in operation of its industrial waste water treatment and disposal system. Trans/Circuits requested and received an informal conference to discuss the allegations of the NOV, which conference was held on October 20, 1982. At the informal conference, DER and Trans/Circuits reached agreement on a resolution of the issues raised by the NOV. On November 4, 1982, a Consent Order was issued by DER, setting forth the parties' agreement and requiring Trans/Circuits to perform certain corrective actions. In the consent order, Trans/Circuits agreed not to discharge industrial wastewaters into waters of the state "without an appropriate and valid permit authorizing such discharge or having otherwise obtained Department authorization." At the time the consent order was issued, Trans/Circuits was operating pursuant to a DER construction permit which was issued for the purpose of allowing Trans/Circuits to make certain modifications to its treatment system to bring the system into compliance with DER effluent standards. The construction permit expired in January 1983, but Trans/Circuits continued to operate. About one month after the construction permit expired, DER notified Trans/Circuits that it was violating the consent order by operating without DER authorization. The parties met to discuss the matter, and agreed that Trans/Circuits would cease operation for one week to conduct bench-scale testing to identify problem areas and possible corrective actions. Trans/Circuits did cease operation and conduct the testing as agreed. Trans/Circuits presented the data resulting from their bench scale testing to DER, and represented that it had identified problem areas that needed correction. DER evaluated the data and agreed to allow Trans/Circuits to operate for a limited time to gather plant effluent quality data which would form the basis for DER's decision whether to allow operation to continue. DER did not take enforcement action to have Trans/Circuits cease operation at that time because DER wanted to give Trans/Circuits time to show that it could comply with the effluent standards as it claimed it could. On March 23, 1983, DER notified Trans/Circuits that there had been a significant improvement in the plant's ability to produce effluent of acceptable quality, and DER authorized Trans/Circuits to make modifications in order to improve effluent quality. DER at that time gave Trans/Circuits authorization to operate for an indefinite period, with the condition that DER would rescind its approval if the program of sampling and system approval did not continue. Trans/Circuits accepted the authorization on DER's terms. On April 12, 1983, DER granted Trans/Circuits' month-to-month authorization to operate ". . . provided continued improvement is made in your system's operation and the Department can reasonably anticipate system compliance." This authorization was in response to a request from Trans/Circuits for 90-day temporary operating approval in order to demonstrate that the system could comply with state standards. By letter dated October 5, 1983, DER withdrew its authorization for month-to-month operation of Trans/Cirouits' facility because it believed that compliance with state standards could no longer be reasonably anticipated. Despite Trans/Circuits' best efforts, the facility was not in compliance and DER had no assurance that continued operation would bring the facility into compliance within a reasonable amount of time. Trans/Circuits has never ceased operation since DER withdrew its month-to-month operating approval. Trans/Circuits has not had a DER permit for construction or operation of the facility since the expiration of their last construction permit in January, 1983. At a meeting on December 1, 1983, Trans/Circuits' general manager admitted that he was aware that Trans/Circuits' was in violation of the terms of the consent order by continuing to operate without DER authorization. Analysis of Trans/Circuits' plant effluent for April 1983, shows that average lead levels were 0.21 parts per million (ppm) (or mg/l), average fluoride levels were 2.45 ppm, while average copper levels were 0.51 ppm. These were the effluent levels existing when Trans/Circuits was granted its month-to- month approval for operation. Since the month-to-month authorization was granted, the majority of Trans/Circuits' effluent samples have not complied with the DER standards for lead, copper, and fluoride. Since April 16, 1984, five percent or less of Trans/Circuits' effluent samples have complied with the effluent standards for lead and copper. In the week or two prior to hearing, the majority of effluent samples contained lead at a concentration of 0.2 to 0-5 ppm (with some higher), and contained copper at a concentration of between 2 and 3.5 ppm (with some higher). The most recent data available indicate that Trans/Circuits is not in compliance with the effluent standards for lead, copper and fluoride. Daily average effluent concentrations for lead and copper are significantly greater now than they were when DER issued its month-to-month authorization. Groundwater samples just outside Trans/Circuits' property show violations of the DER standards for lead. The evidence shows that Trans/Circuits effluent quality has not improved since April 1983. Effluent concentrations of lead and copper have actually increased significantly since October 1983, when DER withdraw its month-to-month authorization. Trans/Circuits does not even expect to know before December 1984, whether its present system can attain compliance with effluent standards. The Construction Permit Application On March 8, 1984, Trans/Circuits applied to DER for a permit to construct modifications and improvements to the existing Havviland wastewater treatment system. Although the stated purpose of the requested construction was to upgrade the system to achieve compliance with the Riviera Beach Sewer Use Code so as to allow a sewer tie-in, Trans/Circuits had abandoned that purpose by the time of the hearing. Trans/Circuits now seeks to upgrade the systems so that the effluent can comply with the applicable standards for discharge to ground water. When DER received the application, it was reviewed by a DER engineer to see if it was complete. The engineer determined it was not complete, and notified Trans/Circuits on April 6, 1984, that additional information was needed to complete the review process, all of which information was necessary to determine whether a permit should be issued for the requested construction. Trans/Circuits' general manager objected to the request for additional information, claiming that all the requested information was not necessary to review the application. However, at the request of Trans/Circuits' counsel, a meeting was held between representatives of Trans/Circuits and DER to discuss the request for information that was needed for review of the application. Trans/Circuits thereafter, withdrew their objections, and agreed to provide the requested information. Trans/Circuits responded to DER's request for additional information on June 27, 1984, at 3:30 P.M. the day prior to hearing. Trans/Circuits delivered a packet of information to DER at that time that purported to be the requested information. Also at that time, however, Trans/Circuits told DER that it had already performed some of the construction for which a permit was sought, and that it was not sure what, if any, of the remaining construction would be undertaken. The information that was submitted to DER was not all of the information requested by DER. No flow diagram was submitted and waste effluent analysis was lacking. Without this information, it is impossible to determine whether or not reasonable assurance has been provided by Trans/Circuits that DER standards will be met. Even if all of the requested information had been submitted, DER could not issue a construction permit to Trans/Circuits because its future construction plans are now only speculative. Trans/Circuits does not know what modifications it intends to construct, or when exactly such modifications will be made. All that is certain is that Trans/Circuits does not intend any longer to construct the modifications for which it made application. DER evaluates applications to determines whether all proposed modifications works as a system. Trans/Circuits is the applicant for this permit and has the burden of showing that it is entitled to issuance of the permit. Here Trans/Circuits failed to present any evidence of what construction it actually plans to do, let alone that the purposed construction meets the criteria and that it is entitled to the permit.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED: That a Final Order be entered by the State of Florida Department of Environmental Regulation: Denying Trans/Circuits application for an operation permit; Denying Trans/Circuits application for a construction permit; and Withdrawing the month-to-month authorization for Trams/Circuits' operation. DONE and ENTERED this 19th day of September, 1984, in Tallahassee, Florida. DIANE K. KIESLING 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 19th day of September, 1984.
The Issue Whether, under the facts and circumstances of this case, Respondent's license to practice engineering in the State of Florida, should be revoked, suspended, or otherwise disciplined.
Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant facts are found: At all times material to this proceeding, Respondent, L. Thomas Hubbard d/b/a The Hubbard Association, was licensed to practice professional engineering in the State of Florida, having been issued license number PE 006634 on August 17, 1962. Certificate of authorization number EB0003297 was issued to the firm, The Hubbard Association, Inc., on September 25, 1981. In March 1986, Respondent prepared a set of plans for the proposed City of Macclenny Wastewater Treatment Works Improvement Program, Sewage Treatment Facility ("Macclenny project"), and one volume of "Contract Documents and Specifications" ("specifications"), which were submitted to the State of Florida Department of Environmental Regulation, Bureau of Wastewater Management and Grants (Bureau) on or about April 24, 1986. All wastewater treatment plans designs must go to the DER for approval prior to construction, and if a public entity wants grant funding for its wastewater treatment facility, the project must be reviewed and approved by the Bureau (now called Bureau of Local Government and Waste Water Financial Assistance) which administers State grant programs for wastewater treatment facilities. The Bureau reviews grant project plans and specifications to ensure that they: (a) comply with administrative requirements of the grants programs; (b) comply with minimum Federal and/or State technical standards for wastewater facilities; (c) are suitable for bidding; and (d) present a constructible project. The plans for the Macclenny project depict an existing treatment facility, a new clarifier to improve the removal of solids (an expansion of about 130,000 gallons per day in treatment capacity), and a new effluent pumping station to pump to an overland flow field (field) through a force main pipeline to spray risers. The risers would spray the water laterally across the field. Water would collect in a central collection ditch, and run through a final chlorine contact chamber prior to discharge in Turkey Creek. A new agricultural building for equipment storage, and a new holding pond, which is an off-line pond for storage of inadequately treated water, are also depicted. The field in the Macclenny project is roughly 24 acres and is located in a large area between the chlorine contact chamber and the holding pond. The field in this system has 5 cells. A cell is an area of land that can be independently controlled to allow loading/resting cycles in the treatment process. Each cell in a given field should be as near equal in size as possible to provide for equal treatment of the wastewater during the loading/resting cycles. Loading/resting cycles allows a cell within the field to "rest" (no effluent being pumped on to that cell) so maintenance mowing or harvesting can be accomplished and to "load" the other cells to revitalize the bacteria that renews the treatment process. "Load" means to apply the effluent or treated wastewater from the existing facility to the field. Generally, forty percent of the field would be loaded with wastewater at any one time. On December 9, 1985, the Bureau had a predesign conference with Respondent in Macclenny to discuss design items. No plans or specifications for the Macclenny project had been submitted at that time, nor were they submitted at this conference. On February 18, 1986, an in-progress design review was held at Macclenny, with the Bureau staff available to answer Respondent's questions. On March 5, 1986, another in-progress design review meeting was held in Macclenny, with the Bureau staff present, at which time the plans were "fifty percent" (50%) complete. The unsigned and unsealed plans were given to the Bureau for a preliminary review. On March 25, 1986, the Bureau issued a few preliminary comments on the 50% completed plans and specifications. The purpose of the 50% complete review is to help the design engineer complete his plans and specifications. On March 31, 1986, Respondent transmitted to the Bureau a set of plans for the proposed Macclenny project. Respondent's transmittal letter, which the Bureau received with the plans on April 11, 1986, stated that "completed plans" were being transmitted. On April 21, 1986, Respondent transmitted to the bureau an additional set of the same plans for the Macclenny project, which Respondent again referred to as "completed plans" on his transmittal letter form which were received by Bureau on April 24, 1986. This transmittal also included specifications, a design data check list, design calculations, cost estimate, and plan of operation. The plans in this submittal are referred to as "the plans." It was Respondent's understanding that signing and sealing a set of engineering drawings signified a legal obligation that if someone takes the plans and builds a project it will work. Respondent's signature and seal are on the first sheet of the set of plans which was in the April 1986 submittal but not on the specifications. The plans were prepared, signed, sealed and submitted to the Bureau for review by Respondent. Respondent did not place any conditional language or qualification on the plans or write a letter advising the Bureau that the plans were not complete. It was Respondent's understanding that the Bureau would not review a set of plans unless they were signed and sealed, notwithstanding the completeness of the plans. Respondent did not consider the plans as completed, notwithstanding that he had signed, sealed and submitted them to Petitioner as "completed". It was Respondent's understanding that the plans were being submitted for review only, not complete for construction. An engineer may get answers from the Bureau without submitting plans that are signed and sealed as completed, such as the predesign conference or 50% review that occurred in this case. The Bureau considers plans that are signed, sealed and submitted as "completed" for review to be 100% complete and ready to bid. The Bureau considered the plans and specifications which Respondent submitted on April 24, 1986 as being final, complete plans and specifications for final review by the Bureau. The Bureau reviewed the plans assuming them to be complete and followed normal procedures for reviewing a complete set of plans and specifications. On June 19, 1989, the Bureau issued 52 written comments based on its review of the plans and specifications it had received in the April 24, 1986 submittal from Respondent. The plans and specifications were submitted to the Department of General Services (DGS) by the Bureau for a review and opinion because the Bureau was concerned about the structural design. DGS responded to this request through Jim Berkstresser, P.E. on June 25, 1986. By cover letter dated July 18, 1989, Respondent filed written responses to the Bureau's 52 comments. The Bureau did not approve Respondent's plans and specifications for the Macclenny project submitted on April 24, 1986. On September 5, 1986, Respondent resubmitted plans in response to the Bureau's 52 comments. These plans had the same configuration as the April submittal regarding the overland flow treatment. On September 29, 1986, Respondent met with David Wolfe to discuss the field configuration for the proposed overland flow system and other outstanding issues related to the revised contract documents. The principal concerns were non- uniform flow and significant erosion potential. Respondent's plans did not follow accepted design criteria. At this meeting field configurations were discussed, as well as guidelines to be followed in design of the overland flow field, and a general field layout were developed. Respondent submitted another set of plans which the Bureau received on October 30, 1986, and that set was approved and stamped accepted by DER-BWMG on December 22, 1986. All sheets in the approved set are dated August 20, 1986, with the exception of the cover sheet on which Respondent failed to date his seal and signature, and sheets G-6 and G-7 which are dated October 24, 1986. Respondent signed and sealed the cover sheet and sheet G-7 of the approved set of plans, but did not seal any other sheets in the approved set of plans. A signature and seal on a set of plans indicates that the plans were prepared by, or under the direct supervision of the person signing and sealing them, and that the plans are complete and depict a project that will perform its intended function. A signature and seal on a set of plans means the engineer assures that the design is his design and that the plans and specifications are ready to be bid for construction. The design should contain criteria and information significant to ensure the project will work. Sheet flow is the primary treatment mode in an overland flow system. Sheet flow is where a thin layer of water is induced to flow in a very controlled atmosphere across a length of land that is functioning very similarly to a trickling filter. The acceptable range of slope of an overland flow system is 2% to 8% with the best results obtained in the lower range because of a longer "residence time". "Residence time" is the amount time the wastewater is on the field for treatment. The slopes must be even and uniform to maintain a constant velocity so as to minimize the potential for erosion and to maintain a constant depth of water throughout the filed so as to maximize the treatment. Cross slopes should be minimized and topographic lines should be as close to parallel as possible on the field. The plans for the Macclenny project shows: (a) slopes ranging from less than 2% up to 6%; (b) multiple compound slopes across the field and; (c) topographic lines that are not parallel. The specifications for the field do not set out the acceptable tolerances on the slopes or the acceptable level of compaction of the field for the contractor who is to construct the field and; therefore, lacks control over the final product. Contours in an overland flow field are important, and while it is desirable for them to be on 1-foot intervals, contours at intervals of 2 feet are acceptable provided the plans and specifications address what happens between the contours. Respondent's plans and specifications show contours at intervals of 2 feet but do not address what happens between the contours. The plans of the facilities that were approved prior to the submittal of any plans by Respondent called for a 2- 3 week loading/resting cycle. The standard practice is to have all cells within an overland flow field to be of equal size so that the area to be loaded at any given period of time is the same size. The cells in the overland flow field in the Macclenny project as depicted by the plans are not of equal size, and if operated on a 2-3 week loading/resting cycle would not provide a consistent amount of treatment and thereby result in varying levels of treatment of the effluent. It is standard practice to provide performance specifications for seeding the field with the primary grass cover and for overseeding when necessary to prevent wind and water erosion. There were no performance specifications in the plans and specifications on the Macclenny project submitted by the Respondent. Agricultural equipment is an integral part of the overland flow field system and has a direct bearing on whether the system will function over the long run. Specifications for agricultural equipment are necessary to determine if the system will work properly. There were no specifications for agricultural equipment submitted by the Respondent in the plans. It is standard practice to furnish spray nozzle specifications, such as nozzle size, degree of fanning, characteristics under varying pressures and how much water will be discharged by the nozzle, in a set of plans and specifications for an overland flow field. Respondent's specifications for the Macclenny project did not contain the necessary specifications for the spray nozzles. Compacting is a standard practice, and it is standard practice to show compaction requirements on plans or specifications. The usual practice is to investigate the soil and specify compaction, usually based on a foundation report by a geo-technical engineer, showing the safe beading capacity of the soil in what condition, with recommendations for compaction. The Respondent's specifications do not call for compaction of the soil under the clarifier slab. However, the Respondent's specifications do call for compaction in the holding pond and situations where an area is over-excavated and backfilled. Should the area under the clarifier slab be over- excavated and backfilled, then compaction is covered in the specifications but compaction would not be covered unless this occurs. Therefore, since the weight of the slab is carried by the soil beneath it, specifications for compaction should have been included in Respondent's specifications for any situation. Changes in temperature causes concrete to expand or contract which may result in cracking. Placement of a concrete slab may result in the slab bending which may result in cracking. Therefore, reinforcing a concrete slab is required to maintain the slab's integrity. The thickness of a concrete slab will determine the distribution of the reinforcing so that cracking is minimized. The clarifier slab in the Macclenny project is depicted as being 12 inches thick and shows number 6 bar reinforcing on 6 inch centers in the top of the slab but no reinforcing in the bottom of the slab. Failure to require reinforcing in the bottom of the slab could result in the slab cracking due to significant changes in temperature and soft spots in the soil beneath the slab. Failure to place reinforcing in the bottom as well as in the top of the slab is not in accordance with standards of the code of the American Concrete Institute (ACI), revised in 1983, and is a structural weakness. The chlorine contact chamber as detailed on sheets 5-6 and 5-7 is like a rectangular concrete box beneath the earth where the earth is within a few inches of the top of the walls. The walls are vertically reinforced with number 4 bars on 12 inch centers placed in the center of the 8 inch thick wall. When the tank is empty the reinforcing bars will be approximately 160 per cent overstressed from the active pressure of the earth. Additional reinforcing is needed in the walls to meet ACI standards. There are deficiencies in the vertical wall reinforcing of the chlorine contact chamber as detailed on sheets 5-6 and 5-7 of the Plans. On sheets 5-3, 5-4 and 5-7 of the plans, reinforcement through the construction joints is incorrectly detailed to assure that cracking of the concrete will not occur. Construction joints occur between different pours of concrete, such as where the walls meet the top of the bottom slab. The concrete bottom of the holding pond as detailed in sheet 5-8 of the Plans is large enough to require expansion joints to prevent cracking as the slab expands and contracts due to changes in the weather, yet no expansion joints are shown for the slab as detailed on sheet 5-8 of the plans. Neither the collection ditches nor the spray riser bases as detailed on the plans show any reinforcing to maintain the integrity of the concrete. While this is not a major structural weakness, it indicates a failure to comply with standard structural engineering practices. Although the plans call for relocation of an existing drainage ditch, the Respondent failed to consult DER regarding the permitting of such drainage ditch. A detention time of 30 minutes is required to properly disinfect wastewater and is-basic knowledge for all civil engineers, yet the plans called for only a fifteen minute detention time. It is standard engineering practice to provide flood level elevations on the site plans. Respondent failed to provide flood level elevations for the Macclenny facility site plans. The plans failed to: (a) provide elevations for high water alarm and pump off settings; (b) provide specifications for flume liner on sheet M-4; (c) show how to close an existing outlet on the chlorine contact chamber; (d) show where an effluent pump station was to be located; (e) show pressure relief valve locations and; (f) indicate quantities for purpose of contract bidding. The specifications list equipment and work items, such as pumping equipment, grit storage tank, case-out assembly, telescoping valve, air diffusers, portable pump, hose and couplings, that are inapplicable to the Macclenny project. There are inconsistencies in the plans and specifications, such as: (a) the plans showing one clarifier while the specifications call for two clarifiers, (b) the plans showing a 150 pound chlorine cylinder as opposed to a 1-ton chlorine cylinder in the specifications and; (c) the plans showing the clarifier with a 38-foot diameter while the specifications calls for a clarifier with a 40-foot diameter. Respondent was negligent in submitting incomplete plans to the Bureau as "completed plans" and in failing to utilize due care and failing to have due regard for acceptable standards of engineering principles, with regard to the content of those plans which he submitted as "completed plans".
Recommendation Having considered the foregoing Findings of Fact and Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the circumstances surrounding this case, it is, therefore, RECOMMENDED that the Board enter a Final Order finding Respondent, L. Thomas Hubbard guilty of violating Section 471.033(1)(g), Florida Statutes, and for such violation impose an administrative fine of $1,000.00 and suspend from the practice of engineering for a period of thirty (30) days, stay the suspension and place the Respondent on probation for a period of one year under terms and conditions the Board deems appropriate.

The Issue Whether Beker Phosphate Corporation should be granted a hermit to construct an industrial waste water facility pursuant to chapter 403, Florida Statutes. By application, dated April 8, 1975, Beker Phosphate Corporation (hereinafter Beker) , sought a permit to construct an industrial waste water facility in Manatee County, Florida, from the Department of Pollution Control (now and hereinafter DER) . The application was received on April 11 and, after advising Beker that the application was incomplete a meeting was held on May 9th between DER and Beker representatives with the result that Beker filed a new application dated June 11, that was received by the DER in July. Further meetings were held in the fall of 1975 and additional in formation was received as to the application. On December 16, 1975, DER secretary. Jay W. Landers, Jr., issued a Notice Of Intent To Grant A Permit With Conditions. The conditions were unspecified in the letter of intent (Exhibit 1.) Subsequently, on December 23 and December 24, 1975, Sarasota County (hereinafter Sarasota) and the Town of Longboat Key (hereinafter Longboat Key), respectively, filed petitions with the DER alleging that their substantial interests would be adversely affected by approval of the permit application and setting forth in their petitions certain disputed questions of fact for determination. After a prehearing conference, Amended Petitions were filed by those parties to clarify and expand on such questions of fact and to resolve procedural matters. Additionally, during this period, George Browning, III, of Sarasota, Florida was granted status as an intervenor.
Findings Of Fact Beker proposes to construct a phosphate rock mine and beneficiation plant on a tract of approximately 11,000 acres in a predominately agricultural and ranching area of Manatee County about 10 miles from Myakka City, Florida. The mining will be performed by two dredges. One will mine overburden and return it to the mined-out area and the other will mine phosphate rock matrix which will be pumped to the beneficiation plant. The plant will consist essentially of two circuits. The first is a washer where the matrix pumped from the dredging operation is partially cleaned of clay and fine sand, and the coarser phosphate particles "pebbles" are separated as a product. The "fines" from the washing operation consist of small phosphate rock particles, sand, and clay. This mixture will be treated in the second section of the plant by "flotation" methods to recover the small phosphate rock particles as a product. During initial operation, the sand and clay will be stored in a temporary waste material storage area, but as the mining proceeds and the dredge pits open up, the sand and clay material will be pumped back to the dredge pits so that sand, and overburden will be mixed and redeposited to reclaim the land. Approximately 8 million gallons of fresh water per day will be drawn from the Floridian aquifer to be used in the flotation circuits. From the plant the water flows in two types of streams--one containing sand suspended in water and one containing clay suspended in water. Both streams flow into a settling pond surrounded by an earthen dam where sand and clay solids settle to the bottom. The clarified water is then decanted through six spillway structures into a hydraulic recirculation ditch outside the dam and flows back to the plant for re-use. The ponds and canals that make up the hydraulic circuit are planned to have sufficient capacity to contain rainwater falling on the site and pond system during the wet season when there are heavy rainfalls (approximately from May to September). Excess water will be decanted from the hydraulic recirculation ditch through a structure into a pipe and then discharged into Wingate Creek. The settling pond will occupy approximately 225 acres and its capacity will be about 8,458 acre- feet. The pond itself can be used to act as a reservoir and water can be built up in the pond during periods of high rainfall. It will not be necessary to release the water at any particular time. It can be released at will when the effluent contains a minimum of pollutant materials (Exhibit 1). Matrix is an unconsolidated mixture of phosphate pebbles and boulders of partly phosphatized limestone, quartz and clay. The washing operation removes unwanted oversized material and fine clays. The purpose of the flotation plant is to recover fine phosphate rock that might otherwise be lost. In the flotation process, flotation reagents, including sulfuric acid, number 2 fuel oil, tall oil, sodium hydroxide, and amines are used for treatment. The wastes are then moved to the settling pond where over a period of time the "slimes", (sands and clays) will settle to the bottom forming an impervious layer which will seal the pond. The settling process removes more than 90 percent of the contaminants from the influent. The coarser clay particles settle first and many of the fine particles settle in a process called "flocculation" by which electrical forces bring the particles together. However, some of the particles will not flocculate and remain suspended in the water. These extremely small particles constitute the total suspended solids that remain in the effluent when it is discharged from the settling area. They probably will not settle out entirely during their course from Wingate Creek into the Myaaka River and eventually to the Gulf of Mexico. However, even if it were assumed that such materials would settle somewhere between the point of discharge and Charlotte Harbor, over the entire 20 year proposed life of the mine they would form a deposit much less than 1/10th of an inch. Although it is technically possible to treat water to the degree that it would result in distilled water, realistic concepts of treatment establish that an additional settling or "polishing" pond for the proposed facility might not improve the quality of the wastewater finally discharged in state waters to any appreciable degree. Alternative proposals for the reduction of pollutants by additional processing, such as the intentional growth of water hyacinths in settling areas or use of chemical coagulants would result in creating other waste materials and thus be counterproductive (Testimony of Bromwell; Exhibit 1). The applicant's discharge of wastewater to Wingate Creek will average approximately 3.19 million gallons per day. However, since discharge will be effected primarily during periods of excessive rainfall, actual discharges can reach a maximum of about ten million gallons per day during this period. The effluent contained in such discharge will meet the test of at least 90 percent removal of organic and inorganic wastes specified by Rule 17-3.04(1), Florida Administrative Code, when measured by the influent into the settling pond and the effluent leaving that area. This treatment, however, will not produce an effluent equivalent to that produced by the "highest quality municipal waste treatment." The highest degree of treatment that has been reached by municipalities is "advanced waste treatment" as defined in Rule 17-3.04(2)(b), Florida Administrative Code. The water quality characteristics of the effluent will meet the standards of Rule 17-3.05 as to concentrations of those pollutants reasonably anticipated to be fond in the wastewater based on samples taken where the waters are discharged into Wingate Creek (Testimony of Gilgallon, Davis, Edwards, Heinzman, Bromwell, Bartow, Wellford, Exhibit 1). In preparing the application, no consideration was given to the need of meeting treatment standards for highest quality municipal waste treatment or advanced waste treatment. Neither did the recommending official of the DER, Mr. Edwards, then Regional Administrator for the Southwest Region, consider this standard because he had been advised by the DER legal staff that Rule 17-3.04(2) did not apply to Wingate Creek since it was not a tributary to one of the bodies of water listed in subparagraph (c) of the rule 17-3.04(2). This determination was based upon Resolution No. 74-83, September 17, 1974, of the Florida Pollution Control Board that was issued after legal challenges had been made to an interpretation by the Department of Pollution Control legal staff that Rule 17-3.04(2) required advanced wastewater treatment for industrial waste discharges. The Board, in its resolution, determined that since evidence had not been taken concerning treatment standards for industrial waste discharges at the time of adoption of the effluent standards for sanitary waste contained in Rule 17-3.04(2), the advanced wastewater treatment standards in the aforesaid rule would not be enforced against industrial dischargers pending full hearings on a new Rule to clearly express the Board's intent in this regard (Testimony of Gilgallon, Edwards; Exhibit 1). Special conditions that the Southwest Region, Department of Environmental Regulation, recommends should be attached to any issuance of a construction permit, other than standard conditions and those relating to other types of permits, are as follow: Approval by DER prior to the construction of any above grade phosphatic clay storage facility other than the initial settling pond. Removal efficiencies for oil and grease shall be a minimum of 90 percent and shall not exceed 14 milligrams per liter measured in the discharge effluent. Discharge effluent to Wingate Creek shall meet the water quality standards of Chapter 17-3.05(2) at the point of discharge prior to mixing with the receiving stream. Further treatment of the discharge will be required in the event compliance with proviso (c) above cannot be achieved or significant degradation of the receiving stream occurs as determined by the DER. In addition to required routine monitoring, a detailed analysis of the untreated and treated wastewater to be conducted once on representative samples during (1) month of July and (2) month of February. Such analyses shall, as a minimum, include all the parameters listed in 17-3:05(2). Applicants shall conduct an investigation into total retention possibilities of the effluent including, but not limited to, the following areas: recharge wells retention and storage of excess water during the "wet" season with subsequent reuse during the "dry" season for process and/or irrigation purposes. A report of these investigations shall be submitted prior to submission of operation permit application The location of monitoring wells shall be down gradient from the settling pond. Detailed proposal, subject to the DER approval, regarding exact location and number of wells to adequately ascertain the impact of seepage to be submitted no later than 90 days prior to commencement of operation. Bond to be posted for damages that may result from a clay settling area dam failure. Oral and written communications from the public were received at the hearing and included the following: Announcement by the County Attorney, Manatee County, that the county did not plan to appeal the DER Notice of Intent to Grant the permit (Statement of E.N. Fay, Jr.). The Division of Recreation and Parks, Department of Natural Resources, fears that the construction of the phosphate mine up-stream from the Myaaka diver State Park poses a serious potential threat to its aquatic habitat due to the possibility of a dam failure. It also fears that pollutants from the project will tend to settle as the river waters flow through the two lakes in the park. It therefore, opposes the construction until assurance can be given that proper safeguards have been taken to prevent such problems (Testimony of Alverez). The Longboat Key Garden Club believes that the project would involve too much water consumption and also that phosphate mining should be halted until further government studies are made to assure that the safety and health of the populace and the environment will not be endangered through polluted runoff and phosphate spills (Testimony of Monroe). The Save Our Bays Association in Manatee County has collected petitions from citizens in Manatee County requesting a referendum on a ballot this November for or against phosphate mining. The Association believes that such a vote should be taken before final decision is made on the subject. Its spokesman fears that if the quality and quantity of the drinking water is disrupted, it will interfere with continued tourist trade (Testimony of Howard Greer). The Palma Sola Parks Association opposes the Beker Application until there is greater assurance of environmentally safe mining (Testimony of Blankenship) A former physical and health education director is concerned about the fact that there has not been sufficient data collected on the effect of radioactive materials in runoff and waste. She believes there should be more research in these areas and asked that the public be protected from such hazards (Testimony of Mary Kay Greer). The Manasota-88 project for environmental qualities of 1968 and 1988 believes that issuance of the permit should be withheld until health implications can be determined concerning potential hazards to the Myakka and Manatee Rivers' watersheds (Exhibit 7). A former member of the Manatee County Planning Commission that approved the Beker application prior to action by the County Commission of Manatee County is in favor of the proposed project because Beker's plan to impound water will augment the water facilities of the county (Testimony of Reasoner). The City of Bradenton believes that since it is being required to meet advanced water treatment standards of discharge for sanitary sewage, Beker Phosphate Corporation should be required to meet similar standards (Testimony of Mayor A.K. Leach). A member of the Myakka City Civic Association who is an adjacent land owner to Beker Phosphate Corporation feels that the project is necessary in order to produce jobs for individuals in that area of the county (Testimony of Mizell). The U.S. Fish and Wildlife Service is concerned that proposed construction of two dams by the applicant will destroy approximately (4) acres of mangrove areas, three acres of pasture land and about 185 acres of bottom land or hardwood habitat. It recommends an alternative method of backup levies constructed around the primary settling bases on the applicant's land to contain any spills and prevent destruction of the streams and associated wetlands (Testimony of Johnston) The Conservation Council of Manatee County believes that Beker's unique mining and reclamation plan will help the farming industry and also create necessary water reserviors and recreation areas, and therefore endorses its proposal to mine in Manatee County (Testimony of Kent, Exhibit 14). Petitions were submitted at the hearing from approximately 3,000 individuals living in Manatee and Sarasota Counties opposing the issuance of the permit because they believe that phosphate mining is dangerous to the quality and supply of the water and endangers the health of the people (Composite Exhibit 9, Testimony of Humphrey).
The Issue The issue in this case is whether Respondent KW Resort Utilities Corp. ("KWRU") is entitled to issuance, by Respondent Department of Environmental Protection ("DEP"), of Domestic Wastewater Facility Permit FLA014951-012-DWIP and UIC Permits 18490-020 and 18490-021 (collectively, the "Permit at Issue"), authorizing the major modification of KWRU's existing permit to operate a domestic wastewater facility located at 6630 Front Street, Stock Island, Florida 33040. The Permit at Issue would authorize the expansion of KWRU's existing domestic wastewater facility and the installation of two additional underground injection wells.
Findings Of Fact The Parties Petitioner Last Stand is a not-for-profit corporation incorporated under Florida law. Last Stand has challenged the Permit at Issue in this proceeding. Petitioner George Halloran is a natural person residing in Key West, Florida, and is a member of Last Stand. Halloran has challenged the Permit at Issue in this proceeding. Respondent KWRU is a Florida corporation. KWRU is the wastewater utility service provider that owns and operates the Existing Wastewater Facility2/ and is responsible for its design, construction, operation, and maintenance. It is the applicant for the Permit at Issue in this proceeding. Respondent DEP is the state agency charged with administering the domestic wastewater program in Florida pursuant to chapter 403, Florida Statutes, implementing, as applicable, rules codified at Florida Administrative Code Chapters 62-4, 62-302, 62-303, 62-520, 62-528, 62-600, and 62-620, and various industry standards and manuals incorporated by reference into DEP rules. DEP's proposed agency action to grant the Permit at Issue is the subject of this proceeding. Background and Overview Domestic Wastewater Regulation in the Florida Keys The State of Florida has recognized the need to protect the Florida Keys' unique, sensitive environmental resources. To that end, portions of the Florida Keys are designated, pursuant to statute and by DEP rule, as an Outstanding Florida Water ("OFW"). § 403.061(27), Fla. Stat.; Fla. Admin. Code R. 62-302.700(9). The Florida Legislature also designated the Florida Keys an Area of Critical State Concern. § 380.0552, Fla. Stat. A stated purpose of this designation is to protect and improve the Florida Keys nearshore water quality through construction and operation of wastewater facilities that meet the requirements of section 403.086(10). Additionally, the Florida Legislature has enacted section 403.086(10), which addresses the discharge of domestic wastewater in the Florida Keys. That statute finds that the discharge of inadequately treated and managed domestic wastewater from small wastewater facilities and septic tanks and other onsite systems in the Florida Keys compromises the coastal environment, including the nearshore and offshore waters, and threatens the quality of life and local economies that depend on these resources. Section 403.086(10) directs that after December 31, 2015, all new or expanded domestic wastewater discharges must comply with the treatment and disposal requirements of the statute and DEP rules. Specifically, domestic wastewater treatment facilities having design capacities greater than or equal to 100,000 gallons per day must provide basic disinfection of the wastewater pursuant to DEP rule and must treat the wastewater to a level of treatment, which, on a permitted annual average basis, produces an effluent that contains no more than the following concentrations of the specified constituents: Biochemical Oxygen Demand ("CBOD5") of 5 milligrams per liter ("mg/L"); Suspended Solids of 5 mg/L; Total Nitrogen, expressed as N of 3 mg/L; and Total Phosphorus, expressed as P of 1 mg/L. Collectively, these effluent standards constitute the "advanced wastewater treatment" ("AWT") standards. Section 403.086(10)(e) also imposes requirements regarding disposal of treated domestic wastewater effluent through underground injection. Section 403.086(10)(e)1. requires Class V injection wells serving domestic wastewater treatment facilities having design capacities of less than one million gallons per day (hereafter "MGD") to be at least 90 feet deep and cased to a minimum depth of 60 feet, or to such greater cased depth and total well depth as may be required by DEP rule. Section 403.086(10)(e)2. requires Class V injection wells serving wastewater treatment facilities with design capacities greater than or equal to 1 MGD, excluding backup wells, to be cased to a minimum depth of 2,000 feet or to such greater depth as may be required by DEP rule. The Existing Wastewater Facility KWRU currently is permitted, pursuant to Permit FLA014591 (the "Existing Permit"), to operate a domestic wastewater facility (the "Existing Wastewater Facility" or "Facility")3/ located at 6630 Front Street, Stock Island, Florida. Stock Island is located immediately east and slightly north of Key West. By way of background, KWRU's domestic wastewater system currently consists of three elements: a collection system, which collects wastewater from serviced properties; a transmission system, which transmits wastewater from the collection system to the treatment plant; and the Existing Wastewater Facility, which treats the wastewater and then sends it either as reclaimed water for reuse as irrigation water at the Key West Golf Club, or for toilet flushing or air conditioning makeup water at other facilities specified in the Existing Permit,4/ or disposes of it as treated effluent through two underground injection wells. No modifications to the collection or transmission systems have been proposed or challenged. Thus, only the proposed modifications to the Existing Wastewater Facility are at issue in this proceeding. The Existing Wastewater Facility serves residential and commercial properties located on Stock Island, Florida, immediately adjacent to Key West in the lower Florida Keys. Specifically, the Facility treats domestic wastewater originating from approximately 1,416 existing residential connections and 216 commercial connections. The commercial connections consist of a convalescent center, a college, restaurants, recreational vehicle parks, an animal clinic, and a hospital. There are no industrial wastewater contributors to the Facility. The Facility includes a Category III, Class C wastewater treatment facility operating under the Existing Permit. It is staffed by a Class C or higher operator for six hours a day, seven days per week, in accordance with the Existing Permit and applicable DEP rules. The Facility has a design capacity and a permitted capacity5/ of .499 MGD annual average daily flow ("AADF") and consists of two treatment trains having capacities of .249 MGD and .250 MGD AADF. These treatment trains are piped together to allow operation of the Facility as a single plant. The Facility was upgraded in the mid-2000s and is capable of treating influent wastewater to AWT. However, as authorized under the Existing Permit, the Facility currently treats domestic wastewater to secondary standards, which do not impose nitrogen or phosphorous limits. Under the Existing Permit and in accordance with section 403.086(10), the Facility is not required to meet AWT standards until January 1, 2016. Vacuum and gravity collection systems collect the domestic wastewater from the properties that KWRU services. Wastewater influent from the collection systems flows through the transmission system to a splitter box at the KWRU property, where it is sent to the Facility for treatment. The Facility contains two treatment trains, each consisting of a bar screen, an equalization tank, an aeration tank, an anoxic zone, a post-aeration basin, a clarifier, a silica sand/river rock filter, and a chlorine contact chamber. The bar screens, which constitute the first step in the treatment trains, remove floatables from the wastewater stream. After passing through the bar screens, the wastewater drops into two equalization tanks. As their name indicates, the equalization tanks smooth out the peaks in wastewater flow to the Existing Wastewater Facility. Specifically, wastewater flows to the Facility in large volumes during two periods each day, morning and evening, corresponding with peak water use by the serviced properties. During these large flow volume periods, the equalization tanks fill up with sewage influent, which is meted out during lower-flow periods for treatment by the Facility. In this manner, the Facility treats roughly the same amount of wastewater per hour, which is key to the steady state operation of, and the reliable treatment of the wastewater by, the Facility. From the equalization tanks, the wastewater is directed to the three-stage bioreactor portion of the treatment process. Microorganisms are utilized at each stage to break down the waste. The first stage of the bioreactor process occurs in the aeration basins. Here, wastewater enters the fine-air zone, where it and the microbes used in this stage of the treatment process come into contact with tiny oxygen bubbles. The microorganisms use the oxygen to oxidize the waste and complete the ammonification of the wastewater. The wastewater then passes through bulkheads to the anoxic zones, where the oxygen level is extremely low. In the anoxic zones, bacteria denitrify, or remove nitrogen from, the wastewater. The wastewater is then sent to the post-aeration basins, where excess carbon is removed through oxidation. Thereafter, the wastewater is sent to the clarifiers, where the microorganisms settle out of the wastewater to form a solid precipitate on the bottom of the tank. The precipitate is plowed into a sump and returned by pump to the bioreactors, where the microorganisms are reused in the activated treatment process. When the microorganisms cease to optimally function in treating the waste, they are culled from the treatment process and sent to a digester, where they oxidize, through the endogenous decay process, to the point that they die and only their endoskeletons remain. Sludge, consisting of the endoskeletons and water, is pumped to a sand filter drying bed. The filtrate water is pumped back through the Wastewater Facility to be reused in the wastewater treatment process, while the dried endoskeletons, which are termed "biosolids," are transported offsite for disposal in a Class I landfill. The treated, clarified wastewater is pumped through sand/rock filters, then to the chlorine contact chambers where it is exposed to a minimum of 15 minutes of chlorine disinfection. As noted above, the Existing Permit authorizes the reuse of reclaimed water for, among other uses, irrigation by land application at the 100.27-acre Key West Golf Club golf course. The golf course irrigation system consists, in part, of two unlined interconnected ponds that do not directly discharge to surface waters6/ and that have a storage capacity exceeding one million gallons. KWRU sends reclaimed water to the golf course through its reclaimed water reuse system only in the quantity required to meet the course's irrigation needs. The Existing Permit imposes a minimum residual chlorine level of 1 mg/L and a maximum of 5 mg/L turbidity for the treated wastewater to be considered reclaimed water that can be reused as irrigation at the golf course or as otherwise authorized in the Existing Permit. If the treated wastewater does not meet these standards, switchover/interlock equipment at the Facility disables the power to the pumps that send the reclaimed water offsite for reuse.7/ At that point, the treated wastewater is considered treated effluent.8/ The effluent fills the effluent wet well and is piped directly to the existing underground injection wells for disposal. Pursuant to the Existing Permit, the effluent is disposed of by gravity flow through two Class V, Group 3, ten- inch underground injection wells bored to a depth of 110 feet and cased to a minimum depth of 60 feet. Collectively, the two injection wells have a maximum permitted capacity of .499 MGD AADF. As authorized by the Existing Permit, the underground injection wells discharge the effluent to Class G-III ground water within the Key Largo Limestone.9/ The underground injection wells are not the primary means of disposal for the treated wastewater, in the sense that they are used to remove effluent from the Facility only if and when reclaimed water is not needed by the golf course or the other receiving facilities, or when the treated wastewater does not meet the required residual chlorine and turbidity limits discussed above. The Existing Permit and the activities authorized thereunder are not at issue in this proceeding. Activities Authorized by the Permit at Issue The Permit at Issue proposes to authorize the construction of a new .350 MGD treatment train, which will increase the design capacity and permitted capacity of the plant from .499 MGD to .849 MGD AADF. The proposed modification of the Existing Wastewater Facility entails the addition of a 90-foot diameter tank containing an influent screen, a 105,554-gallon influent equalization tank, a 163,000-gallon aeration chamber, a 154,725-gallon post-anoxic chamber, a 35,525-gallon re-aeration zone, a 112,062-gallon clarifier, and a 317,950-gallon digester. The sand filters and chlorine contact chambers currently in use will be expanded to accommodate flows from the new treatment train, and the chlorine contact chambers will be changed to liquid bleach feed. The Permit at Issue also proposes to authorize the construction and operation of a new .499 MGD AADF underground injection well system consisting of two new Class V, Group 3 ten- inch wells, drilled to a depth of at least 110 feet and cased to a depth of at least 60 feet, which would discharge effluent to Class G-III ground water within Key Largo Limestone. When placed into service along with the two existing injection wells, the total design capacity and permitted capacity of all four underground injection wells would be .998 MGD AADF.10/ The existing reclaimed water reuse system for the Key West Golf Club or the other receiving facilities currently is authorized for a permitted flow capacity of .499 MGD AADF and a design capacity of 1 MGD AADF. The Permit at Issue would authorize the construction of a new reclaimed water reuse system having a permitted capacity of .849 MGD AADF; however, the design capacity of the system remains 1 MGD AADF, and the amount of reclaimed water sent to the golf course for reuse as irrigation is not being changed by the Permit at Issue from that currently authorized by the Existing Permit. Hereafter, the proposed modifications to the Existing Wastewater Facility that are the subject of the Permit at Issue are referred to as the "Project." The expanded facility resulting from completion of the Project is referred to as the "Expanded Wastewater Facility." The Existing Wastewater Facility treatment trains will be modified to meet the AWT standards as of January 1, 2016. Specifically, an alkalinity control system, a carbon injection system, and an alum injection will be added and certain aspects of the wastewater treatment process will be modified as necessary to meet the AWT standard. The new treatment train proposed as part of the Project will be designed to meet the AWT standards upon operation, which will not occur sooner than 2016. Accordingly, as required by section 403.086(10(d)1., all effluent from the Expanded Wastewater Treatment Facility will meet the AWT standards as of January 1, 2016. As a result of conversion of the wastewater treatment process to AWT, and even assuming all treated effluent is injected down the wells, total nitrogen loading will be decreased from 58 pounds per day to 15.9 pounds per day and total phosphorous loading will be decreased from 14.4 pounds per day to 5.3 pounds per day. This is the case even though the volume of effluent disposed of through the wells may as much as double. Only the activities comprising the Project, which are the proposed to be authorized by the Permit at Issue, are the subject of this proceeding. The Permitting Process The overarching purpose of the wastewater facility permitting process, including permitting of modifications to an existing wastewater facility, is to ensure that the wastewater facility does not discharge wastes to any waters of the state without first being given the degree of treatment necessary to protect the beneficial uses of such waters. This is accomplished by requiring the facility to be designed, constructed, and operated in accordance with applicable DEP rule standards, which incorporate industry standards. Fla. Admin. Code R. 62- 600.100(1). Similarly, the overarching purpose of the Underground Injection Well System permitting process is to protect the quality of underground sources of drinking water and prevent degradation of the quality of other aquifers adjacent to the injection zone that may be used for other purposes. This is accomplished by requiring underground injection wells to be designed, constructed, and operated in accordance with applicable DEP rule requirements and standards. Fla. Admin. Code R. 62- 528.100(1). The Wastewater Facility or Activity Permit Application Form 1, General Information, and Application Form 2A, Permit for Domestic Wastewater Treatment and Reuse or Disposal Facility, which are adopted by rule, are the forms that must be completed and submitted to DEP to receive authorization to modify existing wastewater facilities or construct new wastewater facilities. This form includes a list of requirements, some (but not necessarily all) of which apply to proposed modification of an existing wastewater facility. The form requires that a Florida- licensed P.E. certify that the engineering features of the project have been designed by the engineer in conformance with the sound engineering principles applicable to such projects, and that, in his or her professional judgment, the facility, when properly constructed, operated, and maintained, will comply with all applicable statutes and the rules. The Application to Construct/Operate/Abandon Class I, III, or V Injection Well System, which is adopted by rule, is the application form that must be completed and submitted to DEP to receive authorization to construct and operate a Class V Injection Well System. This application form includes a list of requirements, some (but not necessarily all) of which apply to a specific underground injection well construction project. The form requires that a Florida-licensed P.E. certify that the engineering features of the injection well have been designed and examined by the engineer and found to conform to modern engineering principles applicable to the disposal of pollutants as proposed in the permit application. By signing and sealing the application, the P.E. certifies that, in his or her professional judgment, there is reasonable assurance that the injection well, when properly maintained and operated, will discharge effluent in compliance with all applicable statutes and rules. Once the application forms are submitted, DEP permitting staff reviews the applications and determines whether items on the forms and any materials submitted to support those items are incomplete or need clarification. In that event, staff sends the applicant a Request for Additional Information ("RAI"), requesting the applicant to provide additional information to address incomplete or unclear aspects of the application. Once the applicant has provided information sufficient to enable DEP to review the application for issuance or denial of the permit, DEP determines the applications complete and reviews the project for substantive compliance with all applicable statutory and rule permitting requirements. DEP is authorized to issue the permit, with such conditions as it may direct, if the applicant affirmatively provides reasonable assurance, based on the information provided in the application, that the construction, expansion, modification, operation, or activity of the installation will not discharge, emit, or cause pollution in contravention of DEP standards or rules proposed in the application. Fla. Admin. Code R. 62-4.070(1). If the applicant fails to provide such reasonable assurance, the permit must be denied. Conversely, if the applicant provides such reasonable assurance, the applicant is legally entitled to issuance of the permit. Engineering Design of the Project KWRU retained Weiler Engineering Corporation to design the proposed modifications to the Existing Wastewater Facility and the new underground injection well (again, collectively referred to as the "Project") and to prepare and submit the applications for the Permit at Issue to DEP. Edward Castle and Christopher Johnson prepared the applications for the Permit at Issue. As the applicant, Johnson signed the application documents as required pursuant to the application form. As the engineer of record, Castle signed and sealed the certifications in the application forms, representing that he was the engineer in responsible charge of preparing the Project's engineering documents. Castle's signature and seal on the application forms for the wastewater treatment facility expansion portion of the Project constitute his representation that he designed and examined the engineering features of the wastewater treatment facility expansion; that these features conform to sound engineering principles applicable to the Project; and that, in his professional judgment, the wastewater treatment facility expansion portion of the Project, when properly constructed, operated, and maintained, will comply with all applicable statutes and rules, including the requirement that the effluent meet the AWT standards as of January 1, 2016. Similarly, Castle's signature and seal on the application to construct the new underground injection wells constitute his representation that he designed the engineering features of these injection wells; that the injection wells conform to modern engineering principles applicable to the disposal of pollutants as proposed in the permit application; and that in his professional judgment, there is reasonable assurance that the wells, when properly maintained and operated, will discharge effluent in compliance with all applicable statutes and rules, including the requirement that the effluent discharged through the injection wells meet AWT standards as of January 1, 2016. As previously noted, the design capacity of wastewater treatment portion of the Expanded Wastewater Facility is proposed to be .849 MGD AADF. Castle selected this design capacity based on historic wastewater flows at the Existing Wastewater Facility and foreseeable projected wastewater treatment capacity demand in the future.11/ Specifically, to estimate future capacity demand, Castle considered development agreements, requests for utility service, the existence of scarified property and applicable development density, wetslips, recent property sales, and estimated and proposed in-fill development on Stock Island. He projected residential development wastewater treatment demand based on historic actual flow data from the Monroe County Sanitary Wastewater Master Plan ("Master Plan"), in conformance with the Recommended Standards for Wastewater Facilities, the so- called "Ten States Standards," a wastewater systems design and planning guidance document incorporated by reference in rule 62- 600.300(4). Additionally, Castle applied the estimated sewage flows codified in Florida Department of Health rule 64E-6.008, Table I, System Design Estimated Sewage Flows ("DOH Table I"), to estimate wastewater treatment demand for projected commercial and hotel development uses. Once Castle had projected wastewater capacity demand for residential and hotel/commercial uses at buildout on Stock Island, he factored in an additional 15 percent capacity safety factor to derive the .849 MGD AADF design capacity for the Expanded Wastewater Facility. Castle chose AADF, rather than the maximum monthly average daily flow or three-month average daily flow, as the timeframe for the design capacity based on historical flow amounts to the Existing Wastewater Facility and because of insignificant seasonal variations in historical flows to the Facility.12/ This is because the population on Stock Island contributing flow to the Existing Wastewater Facility is largely comprised of non-seasonal residents and commercial operations.13/ Nonetheless, to ensure the Expanded Wastewater Facility will have adequate capacity to effectively treat wastewater to the required standards during higher flow periods that may result from non- residential seasonal occupancy in the future, Castle assumed year-round, 100 percent occupancy for the projected hotel and commercial development on Stock Island in determining the design capacity for the Expanded Wastewater Facility. Castle estimated a peak hourly flow of 1.273 MGD for the Expanded Wastewater Facility. This figure estimates the maximum flow through the facility on an hourly basis specifically to take into account the diurnal variability of wastewater flow entering the facility. By definition, the peak hourly flow is a maximum hourly flow rather than the sustained flow or volume into or through the facility. The projected maximum hourly flow of 1.273 MGD, which was determined by multiplying the annual average daily flow by a peaking factor of 1.5, is an estimate of the maximum hourly flow wastewater coming into the Expanded Wastewater Facility's equalization tanks. Importantly, it is not the volume of wastewater flow, on an annual average daily basis, that will leave the facility's equalization tanks and flow through the facility's treatment process. Put another way, the 1.273 MGD peak hourly flow is not the Expanded Wastewater Facility's design capacity. As previously noted, the permitted capacity of the wastewater treatment portion of the Expanded Facility also would be .849 MGD AADF. The permitted capacity is the amount, on an annual average daily flow basis, that the wastewater treatment portion of the Expanded Wastewater Facility is authorized to treat and discharge. This metric establishes an absolute limit, on an annual average daily basis, on the quantity of wastewater that can be treated by, and discharged from, the Expanded Wastewater Facility. Also as discussed above, once the two new underground injection wells are installed, the total design capacity of the four wells at the Expanded Wastewater Facility will be .998 MGD AADF. The two new injection wells are being added to ensure adequate disposal capacity for the .849 MGD permitted capacity and, importantly, to accommodate the peak hourly flow. The reclaimed water reuse system currently has an authorized design capacity of 1 MGD AADF, and this is not being changed by the Project, although the permitted capacity is being increased to .849 MGD AADF. As discussed in greater detail below, neither the design capacity nor the permitted capacity of the reuse system is a function of the irrigation application rate per acre of the golf course, and neither represent the amount of irrigation applied to the golf course per day. In determining the design capacity for the Expanded Wastewater Facility, Castle considered wastewater capacity demand for the facility through the year 2020, rather than over a 20- year period. This is because buildout of the properties on Stock Island that will contribute flow to the facility is reasonably projected to occur between 2018 and 2020. After buildout, there will be no additional properties being developed to contribute additional wastewater flows to the Expanded Wastewater Facility. The credible, persuasive evidence establishes that the proposed design capacity of .849 MGD AADF for the Expanded Wastewater Facility is appropriate under rule 62-600.200(19) and other pertinent provisions in chapter 62-600 and conforms to sound engineering principles applicable to the Expanded Wastewater Facility. The credible, persuasive evidence also establishes that the proposed permitted capacity of .849 MGD AADF for the Expanded Wastewater Facility is appropriate under rule 62- 600.200(62) and other pertinent provisions of chapter 62-600 and conforms to sound engineering principles applicable to the Expanded Wastewater Facility. The credible, persuasive evidence further establishes that the Project, when properly constructed, operated, and maintained, will comply with all applicable statutes and rules, including the requirement that the effluent meet the AWT standards as of January 1, 2016. The credible, persuasive evidence also establishes that the underground injection wells, as designed, conform to modern engineering principles applicable to the disposal of pollutants as proposed in the permit application; and that there is reasonable assurance that the wells, when properly constructed, maintained, and operated, will discharge effluent in compliance with all pertinent statutes and rules, including the requirement that the effluent discharged down the injection wells meet AWT standards as of January 1, 2016. DEP Review and Proposed Issuance of the Permit at Issue The wastewater treatment facility and underground injection well applications for the Project were submitted to DEP on April 15, 2014. During DEP's review of the applications for the Project, the question arose whether the 1.273 MGD peak hourly flow stated in the permit application would trigger the so-called "deep well" requirement in section 403.086(10)(e)2. that the underground injection wells be cased to a minimum depth of 2,000 feet. DEP ultimately concluded that the term "design capacity," as used in the statute, referred to an average daily flow rate14/ over a specified period of time——here, a year——for the Expanded Wastewater Facility, rather than the transient peak hourly flow for the facility. Thus, the Expanded Wastewater Facility does not have a design capacity exceeding 1 MGD, so the deep well requirement in section 403.086(10)(e)2. does not apply to the Expanded Wastewater Facility. DEP permit review staff issued one RAI, and KWRU timely provided the requested information. Upon receipt and review of KWRU's response to the RAI, DEP deemed the application for the Permit at Issue complete. DEP staff reviewed the permit applications for compliance with applicable statutory and rule requirements and standards. DEP's review does not entail re-designing or re- engineering the project or questioning the design engineer's reasonable exercise of judgment on design matters, as long as the project is accurately designed based on sound engineering principles and will operate in accordance with the applicable permitting requirements and standards. Thus, as a matter of practice, DEP relies, to a large extent, on the design engineer's certification that the system is accurately designed according to sound engineering principles——as is appropriate and authorized pursuant to the certification provisions on the application forms, rule 62-4.050(3), and chapter 471 and Florida Board of Engineering rules.15/ Gary Maier, P.E., professional engineer supervisor III and supervisor of DEP's domestic wastewater facility permit review staff, also reviewed the applications, the Intent to Issue, and the draft Permit at Issue to ensure that the Project complied with all applicable rules and standards and that KWRU had provided reasonable assurances such that the Project should be approved. Ultimately, DEP determined that KWRU provided reasonable assurances that the relevant permit applications met the applicable statutory and rule requirements and standards. Accordingly, DEP issued a Notice of Intent to issue the Permit at Issue. Establishment of Prima Facie Entitlement to Permit at Issue The relevant portions of the permit file, including the permit applications, supporting information, and Notice of Intent to Issue for the Permit at Issue, were admitted into evidence at the final hearing. With the admission of these documents into evidence, KWRU established its prima facie case demonstrating entitlement to the Permit at Issue. See § 120.569(2)(p), Fla. Stat. Challenge to the Permit at Issue Once KWRU demonstrated prima facie entitlement to the Permit at Issue, the burden shifted to Petitioners to present evidence proving their case in opposition to the Permit at Issue. See id. To prevail in this proceeding, Petitioners bear the ultimate burden of persuasion to prove their case by a preponderance of the competent substantial evidence. Petitioners have raised numerous grounds in the Second Amended Verified Petition for Formal Administrative Hearing16/ that they contend mandate denial of the Permit at Issue. Each of these grounds is addressed below. Alleged Permit Application Deficiencies Petitioners contend that the Permit at Issue should be denied due to alleged deficiencies in the applications submitted for the Project. Capacity Analysis Report Petitioners allege that, under rule 62-600.405, KWRU was required to submit a Capacity Analysis Report ("CAR") as part of its application for the Permit at Issue and that its failure to do so renders the applications incomplete, thus requiring denial of the Permit at Issue. The purpose of a CAR is to analyze capacity at an existing wastewater facility and to apprise DEP when it becomes evident that expansion of the wastewater facility may be needed. Specifically, the CAR is performed and submitted on a periodic basis, or when certain contingencies occur, to apprise DEP of the actual flows through the facility. If the actual flows are approaching the facility's permitted capacity, the CAR serves to notify DEP that expansion of the facility may be warranted. Thus, the CAR helps ensure that the permittee recognizes the need for, and properly plans for, future expansion of the facility. In support of their contention, Petitioners presented the testimony of William Lynch, a Florida-licensed P.E., who has experience in the planning and design of wastewater treatment facilities in Florida, including the Florida Keys. Lynch testified that the most recent three-month average daily flows reported to the DEP by KWRU repeatedly exceeded 50 percent of the permitted capacity of the Existing Wastewater Facility, thereby triggering the requirement in rule 62-600.40517/ that a CAR be submitted. KWRU previously submitted an initial CAR when the Existing Wastewater Facility historically exceeded 50 percent of its permitted capacity. Thereafter, KWRU submitted an updated CAR in April 2012, as part of the renewal application for the Existing Permit that KWRU filed in October 2011. The April 2012 CAR indicated that permitted flows would not be exceeded for ten years. Thus, under rule 62-600.405(5), a subsequent updated CAR would be due at five year intervals or when the applicant applied for an operation permit or renewal of an operation permit, whichever occurred first.18/ The persuasive evidence establishes that during the period between issuance of the Existing Permit in February 2012 and submittal of the applications for the Permit at Issue in 2014, the three-month average daily flows for the Existing Facility had not exceeded 50 percent of the treatment plant's capacity and the five-year interval CAR submittal interval (which would have expired in 2017) had not yet expired, so an updated CAR was neither required nor submitted. When development on Stock Island resumed in the 2012 through 2014 timeframe following an economic recession, it became apparent from actual flow data that the Existing Wastewater Facility would need to be expanded to accommodate the wastewater flow from new development, as well as to accommodate wastewater flow from existing development being required by law to connect to a central wastewater system. Accordingly, in April 2014, KWRU submitted the applications for the Permit at Issue. As part of KWRU's applications, the design and permitted capacity of the Existing Wastewater Facility were analyzed, and future wastewater flows for the facility were projected, taking into account all relevant factors, including projected development over an appropriate planning period, new connections from existing development, and the lack of seasonal variation in historic flows. Based on this information, the proposed design and permitted capacities for the Expanded Wastewater Facility were determined. This information is precisely that which would have been required in an updated CAR. Because all pertinent information necessary to determine the design and permitted capacities for the Expanded Wastewater Facility was submitted as part of the applications for the Permit at Issue, a separate CAR was not required and, indeed, would have been redundant and pointless. It should be noted that the Permit at Issue specifically requires submittal of a CAR upon renewal, which is five years from the date of issuance. Further, the Expanded Wastewater Facility is subject to chapter 62-600, including rule 62-600.405, so KWRU would be required to submit a CAR if circumstances specified in the rule were to occur.19/ Thus, Petitioners failed to demonstrate, by a preponderance of the competent substantial evidence, that a CAR was required to be submitted as part of applications for the Permit at Issue. Accordingly, the absence of a CAR as part of the applications is not a basis for denying the Permit at Issue. Deep Injection Well Requirement Petitioners contend that the design capacity for KWRU's wells exceeds 1 MGD, so KWRU was required under section 403.086(10)(e)2. to apply for approval to install deep injection wells——i.e., wells that are cased to a minimum depth of 2,000 feet. Petitioners further contend that KWRU's failure to include an application for deep injection wells in its applications thus mandates denial of the Permit at Issue. Under section 403.086(10)(e)1., injection wells serving wastewater facilities that have a design capacity of less than 1 MGD are required to be at least 90 feet deep and cased to a minimum depth of 60 feet. Under section 403.086(1)(e)2., injection wells serving wastewater facilities having a design capacity equal to or greater than 1 MGD must be cased to a minimum depth of 2,000 feet or such greater depth as may be required by DEP rule. As previously discussed, rule 62-600.200(19) defines "design capacity" as "the average daily flow projected for the design year which serves as the basis for the sizing and design of the wastewater facilities." The rule states that the design capacity is established by the permit applicant, and that the timeframe associated with the design capacity——such as annual average daily flow, maximum monthly average daily flow, or three- month average daily flow——also is specified by the applicant. Additionally, rule 62-600.400(3)(a), which is part of DEP's Design Requirements rule for domestic wastewater facilities, reiterates that the applicant establishes both the design capacity and the timeframe used to define its selected design capacity, with the caveat that the timeframe selected must reflect seasonal variations in flow, if any. As discussed above, the credible, persuasive evidence establishes that KWRU's selected design capacity and timeframe ——here, .849 MGD AADF——accurately and appropriately addresses the projected wastewater flows that will be treated by the Expanded Wastewater Facility. As Castle credibly testified, historical flows to the Existing Wastewater Facility do not indicate substantial seasonal residential flow, consistent with the workforce population residing year-round on Stock Island. Moreover, to the extent there may be some seasonal flow variation associated with projected hotel and commercial development, Castle took that into account in determining the design capacity for the Expanded Wastewater Facility. For these reasons, Castle's selection of AADF as the design capacity metric is appropriate, conforms to sound engineering principles, and complies with applicable DEP rules. Further, as previously discussed, the 1.273 MGD peak hourly flow is exactly that——the peak or maximum flow expressed on an hourly basis——that can be processed by the Expanded Wastewater Facility. It does not constitute the design capacity of the Expanded Wastewater Facility, which, by definition, is the average flow over a specified period of time. The persuasive evidence in the record shows that the proposed design capacity of the Expanded Wastewater Facility is .849 MGD AADF, and this design capacity is appropriate and based on sound engineering principles. As such, the design capacity of the facility is less than 1 MGD, so the deep well requirement in section 403.086(10)(e)2. does not apply to the Project. Thus, Petitioners failed to demonstrate, by a preponderance of the evidence, that the deep well requirement in section 403.086(10)(e)2. applies to the Project. Accordingly, they did not establish that the Permit at Issue should be denied on the basis that KWRU did not apply for approval of deep injection wells as part of the applications for the Project. Identity of Permittee The Permit at Issue is proposed to be issued to Key West Resort Utilities Corporation, which is not an existing entity registered to do business in Florida or in any other state. Petitioners contend, and KWRU and DEP do not dispute, that a permit issued to an entity that does not legally exist cannot legally authorize any activities. Accordingly, to the extent the Permit at Issue is proposed to be issued to Key West Resort Utilities Corporation, Petitioners contend that this constitutes a basis for denying the Permit at Issue. At the hearing, DEP and KWRU presented credible evidence showing that the correct permittee is KW Resort Utilities Corp., not Key West Resort Utilities Corporation as was stated on the proposed Permit at Issue. Further, the permit applications correctly identify KWRU as the applicant for the Permit at Issue. Thus, identification of Key West Resort Utilities Corporation as the permittee on the proposed Permit at Issue was a typographical error, and the evidence establishes that this error will be corrected when the Permit at Issue is issued. If this typographical error is corrected, then the Permit at Issue should not be denied on this basis. Alleged Project Design and Engineering Deficiencies Petitioners allege that KWRU failed to provide reasonable assurance, based on a preliminary design report, plans, test results, installation of pollution control equipment, or other information, that the construction, modification, or operation of the Expanded Wastewater Facility will not discharge or cause pollution in contravention of chapter 403 and applicable DEP rules. Petitioners further allege that KWRU has undersized the design capacity of the Expanded Wastewater Facility and that the appropriate design capacity is greater than 1 MGD, thus triggering the deep well requirement in section 403.086(10)(e)2. Projected Flows to Expanded Wastewater Facility In support of their position, Petitioners presented the testimony of William Lynch, a Florida-licensed P.E., who testified that the future wastewater flows to the Expanded Wastewater Facility projected by KWRU in its applications are incorrect because they do not accurately address planned development in KWRU's service area, as required by the Ten States Standards. Lynch took the position that pursuant to the Ten States Standards, the appropriate planning horizon for the Project is at least ten years, which would require KWRU to project wastewater flow to the Expanded Wastewater Facility through approximately 2025, rather than through 2020, as projected in the applications for the Project. However, the persuasive evidence shows that KWRU utilized an appropriate planning horizon in projecting future wastewater flows to the Expanded Wastewater Facility. KWRU's facility design engineer, Castle testified, persuasively, that although the graphic submitted in the application shows the projected wastewater flows only through the year 2020, the planning horizon he used actually was infinite. This is because the projected buildout of the service area20/ to maximum wastewater flow is anticipated to occur between 2018 and 2020, and after that point, wastewater flows to the facility would remain constant. Thus, it was pointless to depict projected flows out to the year 2025——particularly since the narrative in the application describing the Project makes clear that buildout of KWRU's service area is anticipated to occur by 2020. Because the wastewater flows projected for the year 2020 accurately represent the maximum flows that the Expanded Wastewater Facility can process, the projected planning horizon to the year 2020 is appropriate for the facility, complies with the Ten States Standards, and complies with DEP rules. Lynch also asserted that the projected wastewater flows to the Expanded Wastewater Facility from development identified in the application do not accurately apply the standards in DOH Table I and that this inaccuracy further contributed to underestimation of the design capacity of the Expanded Wastewater Facility. Lynch arrived at this position by applying Table I to all identified future development——both residential and nonresidential——and considering an additional development (Key West Harbor Yacht Club) not listed in the applications. He projected that the future wastewater flow from these developments would be approximately 146,110 gallons per day——approximately 46,000 gallons per day higher than the 100,000 gallons per day that Lynch claimed KWRU projected for the planned developments on Stock Island. Based on the addition of 46,000 gallons to KWRU's proposed design capacity of .849 MGD, Lynch opined that .895 MGD is the design capacity that should have been proposed for the Expanded Wastewater Facility. However, the credible, persuasive evidence establishes that, in determining the design capacity of .849 MGD for the Expanded Wastewater Facility, Castle accurately projected the wastewater flow quantities from future development on Stock Island. Castle described in detail the process he undertook to determine the projected wastewater flows from the various land uses and locations on Stock Island through projected buildout between 2018 and 2020. Specifically, he identified planned nonresidential development on Stock Island expected to begin producing wastewater flows in 2014 and applied the DOH Table I standards to determine the projected flows for each development. To determine projected wastewater flow from future residential development on Stock Island, Castle identified approximately 40 acres of scarified or under-utilized property in KWRU's service area and applied a density of 12 equivalent dwelling units ("EDU") per acre,21/ with 167 gallons per day of wastewater flow attributable to each EDU, using actual historic wastewater flow data from the Master Plan. Additionally, for each scarified or under-utilized property having water frontage, he projected one boat slip per 35 feet of frontage and applied a 75-gallon-per-day flow for each boat slip using DOH Table I recreational vehicle flows. For years 2016 through 2019, Castle projected incremental increases in wastewater flows per year22/ to account for potential development of other currently occupied properties. The aggregate of all projected flows from the identified developments, the 40 acres and boat slips, and the incremental increases per year through buildout yielded a projected wastewater flow of .74 MGD to the Expanded Wastewater Facility by years 2018 through 2020, which represents buildout flow to the facility. Castle then added a "safety factor" of 15 percent to the projected .74 MGD wastewater flow to accommodate currently unknown future redevelopment of existing occupied properties, to reach the .849 MGD design capacity. The 46,000-gallon discrepancy between Lynch's .895 MGD design capacity calculation and Castle's .849 MGD design capacity calculation is attributable to four basic differences in how they each determined design capacity. First, Lynch used more recent development agreement and development order information that more precisely identified and quantified specific land uses than the information that KWRU had available to it at the time it prepared and submitted its application. However, the evidence did not establish that the flow information on which Lynch relied and that on which Castle relied were so appreciably different as to significantly affect the projected design capacity for the Expanded Wastewater Facility. Second, Lynch applied DOH Table I to project future wastewater flows from all future planned development on Stock Island, both residential and nonresidential, whereas Castle applied DOH Table I only to determine nonresidential development future flows, and used actual historic flow data from the Master Plan to determine residential development future flows. Castle's residential flow calculation using historical actual flow data conforms to the recommendation in section 11.242(a) of the Ten States Standards that actual flow data be used, to the extent possible, to predict future flows; thus, Castle's calculation likely more precisely projects future flow attributable to residential development on Stock Island.23/ Third, Lynch took into account the Key West Harbor Yacht Club flow into the Expanded Wastewater Facility, whereas KWRU did not consider this flow in projecting future flows to the facility. This omission constituted an oversight on KWRU's part, and the flow from this development should have been included in the wastewater flow projection for the facility. However, the persuasive evidence did not show that this omission constituted a significant error in KWRU's .849 MGD AADF design capacity projection.24/ Fourth, Lynch apparently misinterpreted a statement in the application referencing "such redevelopment" as referring to the known planned developments on Stock Island, which were specifically identified by name in the application, and, thus, interpreted the reference to 100,000 gallons as being the flow KWRU projected for those known, named developments. However, the persuasive evidence established that the 100,000 gallons that KWRU assigned to "such redevelopment" in its application referred not to the known, named developments identified in the application, but instead to presently unknown future development on Stock Island, which Castle took into account by including the 15 percent "safety factor" in determining design capacity. Pursuant to the foregoing, it is determined that KWRU demonstrated, by credible, persuasive evidence, that it accurately estimated future wastewater flows from projected development on Stock Island to determine an appropriate design capacity of .849 MGD AADF for the Expanded Wastewater Facility. Design Capacity Timeframe Petitioners allege that the timeframe associated with the design capacity specified by KWRU——the annual average daily flow, or AADF——is not appropriate for the Expanded Wastewater Facility because it fails to reflect seasonal flows to the facility as required by rules 62-600.200(16) and 62-600.400(3)(a). Petitioners assert that the design capacity for the facility should instead be expressed in maximum monthly average daily flow ("MMADF") to account for seasonal flows. In support, Petitioners presented the testimony of Lynch, who opined that the KWRU service area experiences seasonal flows driven by the influx of tourists to Stock Island during tourist season. Lynch based this opinion on the wastewater flow data for the Existing Wastewater Facility for the year 2014, and his calculations showing that the three-month average daily flow ("ADF") for October through December 2014 was 11 percent higher than the AADF and that the MMADF for that period was 16 percent higher than the AADF. Lynch considered this variation substantial enough to indicate seasonality, so that MMADF is the appropriate design capacity timeframe for the Expanded Wastewater Facility. Using MMADF as the design capacity timeframe, Lynch opined that the design capacity of the Expanded Wastewater Facility should be 1.04 MGD MMADF——which would trigger the deep well requirement in section 403.086(10)(e)2. Castle chose AADF as the timeframe for the Expanded Wastewater Facility design capacity because historical flow records over a period of years do not show significant seasonal variations in flow for Stock Island. Castle testified, credibly and persuasively, that while the historical flow data shows a consistent slight increase in flows from August to December, in his view, the variation is not significant enough to constitute a seasonal flow. This is consistent with the evidence establishing that Stock Island is a "bedroom community" having a mostly year- round workforce population. Lynch formulated his opinion regarding appropriate design capacity using 2014 flow data for the entire year, which was not available at the time KWRU filed its permit applications for the Project in April 2014. Although Lynch relied on more recent data, his opinion was based only on one year of data. By contrast, Castle selected AADF as the design capacity metric based on the previous five years of flow data, which showed variations in flow ranging between two percent and 12 percent on a three-month average daily flow basis. Castle credibly testified that these variations were not significant enough to indicate seasonal flows and did not closely correlate with tourist season in the Keys. Additionally, in calculating his flow projections for the Expanded Wastewater Facility, Castle assumed 100 percent year-round occupancy for residential units, so that his projected design capacity of .849 MGD necessarily took into account potential seasonal flows. Thus, to the extent there are seasonal flows, the facility simply will receive flows below the design capacity during off-season. The undersigned finds Castle's use of long-term historical flow data more reliable than Lynch's use of only one year of data in assessing whether there is flow seasonality.25/ DEP's wastewater permitting supervisor, Gary Maier, concurred that the variations in wastewater flow do not reflect a significant seasonal variation that would require the use of a smaller averaging period than AADF. Maier also observed that none of the wastewater facilities in the Florida Keys having a design capacity greater than 100,000 gallons per day has a design capacity based on MMADF. This evidences that Castle's selection of AADF as the timeframe metric conforms to the design capacity standard used for facilities of comparable size in the Florida Keys. Based on the foregoing, it is determined that KWRU's selection of AADF as the design capacity timeframe metric for the Expanded Wastewater Facility is appropriate and complies with DEP rules. Petitioners failed to demonstrate that KWRU's selection of AADF as the design capacity timeframe metric violates any applicable laws or rules. Accordingly, Petitioners did not demonstrate that the Permit at Issue should be denied on this basis. Ability of Expanded Wastewater Facility to Reliably Meet AWT Petitioners further allege that KWRU failed to provide a complete application demonstrating that the treatment processes for the Expanded Wastewater Facility will efficiently and reliably meet effluent limitations for design year flow. As discussed above, the evidence establishes that KWRU provided all of the information required for the applications for the Permit at Issue, so DEP correctly determined that the applications were complete before commencing its substantive review of the applications. Also as discussed above, Lynch opined that the proposed design capacity was undersized for the flows he projected for the Expanded Wastewater Facility. However, the persuasive evidence shows that KWRU's proposed design capacity of .849 MGD AADF is appropriate, conforms to sound engineering principles, and meets applicable statutory and rule requirements. In order to ensure that a wastewater facility functions effectively and reliably, it is important that the facility not be substantially oversized for the amount of wastewater flowing into the facility. In an over-sized facility, inconsistent timing of wastewater flow, lack of appropriate chemical environment for waste breakdown, and inadequate food supply for the microorganisms may lead to ineffective performance of the facility. A consequence of these imbalances is that undesirable microbes may populate the facility, causing incomplete solids settlement, overflow of solids downstream to the filters, and operational problems resulting in failure of the facility to treat wastewater to AWT standards. KWRU provided reasonable assurance, based on the proposed .849 MGD AADF design capacity and the other engineering features of the Project, that the Expanded Wastewater Facility is appropriately sized and will effectively and reliably treat the wastewater to AWT standards. Thus, Petitioners failed to prove that the Permit at Issue should be denied on the basis that it is undersized and will not reliably meet AWT standards. Key West Golf Club Reuse System Issues Petitioners contend that as part of the applications for the Project, KWRU proposes to send 1 MGD of reclaimed water to the golf course. Petitioners claim that, given an irrigated area of 100.27 acres and an average irrigation rate of .73 inches per acre per day, only 300,000 gallons of reclaimed water per day is accounted for by reuse as irrigation. On that basis, Petitioners allege that KWRU has not demonstrated that the 700,000 gallon-per-day balance of reclaimed water sent to the golf course will be reused for a beneficial purpose rather than being disposed. This contention is based on a misunderstanding of the structure and function of the reuse system. The 1 MGD flow stated in the permit application is the design capacity of the reuse system, which is not being changed by the Permit at Issue. Importantly, this figure does not quantify the amount of water that is or actually will be sent to the golf course or applied as irrigation to the golf course irrigated area in a single day. Rather, it represents the flow capacity to which the reuse system is designed.26/ The applications for the Permit at Issue do not propose any changes to the quantity of reclaimed water being reused, which is governed by the irrigated acreage at the golf course and the irrigation rate. These parameters are not being changed. As previously discussed, KWRU sends reclaimed water to the golf course only on an as-needed basis, where it is stored in the ponds until needed for irrigation. If the course does not need reclaimed water sent to the ponds, KWRU does not send the water. Thus, the golf course controls the amount of reclaimed water that is sent to the storage ponds. Although the permitted capacity of the reuse system is being expanded from .499 MGD AADF to .849 MGD AADF, the actual amount of reclaimed water sent to the golf course by KWRU is not anticipated to change because, as discussed above, the amount being reused for irrigation is not being changed. Since the amount of reclaimed water being reused for irrigation is not increasing, the reuse system is not being expanded. Thus, the evidence does not show that 700,000 gallons per day of reclaimed water will be sent to the golf course for disposal, inconsistent with rule 62-610.810(2), rather than being reused for a beneficial purpose.27/ Petitioners also assert that the increased permitted capacity of the reuse system constitutes a "new or expanded reuse or land application project," so that an engineering report and reuse feasibility study were required as part of the applications for the Permit at Issue, pursuant to rule 62-610.310(1). KWRU previously provided these documents when it originally applied for authorization of the reuse system. The credible, persuasive evidence shows that increasing the permitted capacity of the reuse system does not trigger the requirement to submit another engineering report or reuse feasibility study. This is because no changes to the structural components or operation of the reuse system facilities are proposed. As Castle credibly explained, and Maier confirmed, the relevant question in determining whether an engineering report is required is whether the land application rate and/or the irrigated acreage is being changed, which would increase the amount of reclaimed water being reused and, thus, would require expansion of the reuse system. As discussed, neither the irrigated area nor the irrigation application rate is proposed to change under the Project. Thus, neither an engineering report nor a reuse feasibility study are required as part of the applications for the Permit at Issue. Therefore, Petitioners failed to demonstrate that the Permit at Issue should be denied on the basis that KWRU did not submit a reuse feasibility or engineering report as part of its applications for the Permit at Issue. Alleged Surface Water Quality Violations by Injection Wells Petitioners allege that disposing of the effluent from the Expanded Wastewater Facility through the injection wells will cause or contribute to violations of surface water quality standards codified in chapter 62-302. Petitioners further allege that, as a consequence, the discharge will violate antidegradation requirements in rules 62- 4.242, 62-302.300, and 62-302.700(1), and that the wells do not comply with the underground injection control rule requirement in rule 62-528.630(7), specific to Monroe County, that the wells not cause or contribute to surface water quality violations. Regulatory Status of Surface Waters in Stock Island Vicinity A significant portion of the surface waters in the Florida Keys, including those surrounding Stock Island and Key West, are classified as Class III surface waters pursuant to rule 62-302.400. Water quality criteria adopted by rule for Class III surface waters are established to protect fish consumption, recreation, and the propagation of a healthy, well- balanced population of fish and wildlife. As previously noted, certain portions of the Florida Keys, including the surface waters surrounding Stock Island and Key West, are designated an OFW. Fla. Admin. Code R. 62- 302.700(9)(i)13. No degradation of surface water quality, other than that allowed under rules 62-4.242(2) and (3), is permitted in an OFW. See Fla. Admin. Code R. 62-302.700(1). The narrative nutrient criterion codified at rule 62- 302.530(47)(a) states: "[t]he discharge of nutrients shall be limited as needed to prevent violations of other standards contained in this chapter. Man-induced nutrient enrichment (total nitrogen or total phosphorus) shall be considered degradation in relation to the provisions of Rules 62-302.300, 62-302.700, and 62-4.242, F.A.C." The narrative nutrient criterion codified at rule 62-302.530(47)(b) states: "[i]n no case shall nutrient concentrations of a body of water be altered so as to cause an imbalance in natural populations of aquatic flora or fauna." These criteria apply in Class III surface waters, including the surface waters in and around the Florida Keys. See Fla. Admin. Code R. 62-302.531(1). Rule 62-302.531(2) requires DEP to numerically interpret the narrative nutrient criterion for nutrients (nitrogen and phosphorus) and for nutrient response (chlorophyll- a). Where a site-specific numeric interpretation of rule 62- 302.530(47)(b) has been established, that numeric interpretation constitutes the primary standard applicable to that site. Fla. Admin. Code R. 62-302.531(2)(a). A range of natural factors affect nutrient loading for a given waterbody. Therefore, site- specific numeric interpretations of the narrative nutrient criteria generally are deemed more reliable than broadly applicable, non-site specific criteria. Estuary-specific numeric interpretations of the narrative nutrient criterion in rule 62-302.530(47)(b), consisting of nutrient values for nitrogen and phosphorus and a nutrient response value for chlorophyll-a have been adopted for many areas in the state of Florida, including the Florida Keys. These numeric interpretations——commonly referred to as "numeric nutrient criteria," or "NNCs"——are open water, area-wide averages. See Fla. Admin. Code R. 62-302.532(1). For the Florida Keys, seven Florida Keys Marine Nutrient Regions ("FKMNRs") have been identified and geographically delineated on a series of maps adopted by rule. For each of these FKMNRs, NNCs have been adopted for nitrogen, phosphorus, and chlorophyll-a. Fla. Admin. Code R. 62- 302.532(1)(g). The NNCs for the Lower Keys Region and the Back Bay Region are germane to this proceeding. For the Bay Back Region, the NNCs are .009 mg/L for phosphorus, .25 mg/L for nitrogen, and .3 µg/L for chlorophyll-a. For the Lower Keys Region, the NNCs are .008 mg/L for phosphorus, 0.21 mg/L for nitrogen, and 0.3 µg/L for chlorophyll-a. These NNCs are expressed as annual geometric means that are not to be exceeded more than once in a three-year period.28/ The area of water extending from the shoreline out to 500 meters offshore in the Florida Keys is referred to as the "Halo Zone." DEP has adopted by rule a map delineating the Halo Zone. The NNCs applicable to surface waters in each of the FKMNRs currently do not apply to the surface waters in the Halo Zone. Thus, only the narrative nutrient criteria codified at rules 62-302.530(47)(a) and (b) apply to surface waters in the Halo Zone at this time.29/ Additionally, pursuant to chapter 62-303, the Impaired Waters Rule, DEP has identified and delineated spatial assessment areas in waterbodies based on homogeneity for multiple water quality parameters.30/ These assessment areas, called "Waterbody IDs" or "WBIDs," are delineated for purposes of assessing, through water quality sampling, whether the surface waters within the WBID are impaired——that is, whether they fail to meet one or more of the applicable water quality standards due to pollutants.31/ DEP has delineated several WBIDs, identified by number, in the Halo Zone surrounding Key West and Stock Island. The Halo Zone surrounding Stock Island comprises WBID 6014B, and the Halo Zone surrounding Key West consists of WBIDs 6014A and 8073A through 8073H.32/ The Back Bay Region, which is located north of Stock Island and outside of the Halo Zone, is designated as WBID 8074. The Lower Keys Region consists of WBID 8073, which is located northwest of Stock Island and surrounding Key West outside of the Halo Zone, and WBID 8079, which is located south of Stock Island outside of the Halo Zone. Water quality monitoring, consisting of sampling for a range of parameters, is conducted at monitoring stations within each of these WBIDs. At least one monitoring station is located within each WBID. This water quality sampling is conducted according to DEP's applicable standard operating procedures. The monitoring stations have collected nutrient and nutrient response data spanning a period of years. The data collected in 1995 through 2013 are pertinent to this proceeding.33/ The Keys RAP, which was prepared in 2008 and updated in 2011, prescribes specific management activities to be implemented to restore surface water quality in the Florida Keys, including eliminating cesspits and onsite septic tank systems and connecting wastewater generators to centralized wastewater systems that treat the wastewater to AWT standards. As authorized under rule 62-303.600, DEP determined that the Keys RAP provides reasonable assurance that the restoration goals for the surface waters in the Florida Keys will be achieved by ensuring that all management activities specified in the Keys RAP would be implemented for specified waterbodies by 2015. Accordingly, in February 2012, DEP approved and adopted the Keys RAP by Secretarial Order. Current and historic water quality data show that all WBIDs in the Keys, including those in the Lower Keys Region, Back Bay Region, and Halo Zone for the surface waters surrounding Key West and Stock Island, are not impaired for nutrients——that is, that the NNCs and narrative nutrient criteria, as applicable, are being met. Pursuant to sections 403.061 and 403.067, Florida Statutes, and rule 62-303.600, DEP has classified the Florida Keys WBIDs as Category 2 under the waterbody use attainment classification scheme34/ for nutrients and nutrient response. The classification of the Keys WBIDs in this category means that sufficient water quality data are available to determine that at least one designated use is attained. Thus, as authorized by section 403.067 and rule 62-303.600(2), DEP has placed the Keys WBIDs on the "Delist List."35/ This "de-listing" action recognizes that the Florida Keys WBIDs, including those in the Halo Zone, are not impaired for nutrients and chlorophyll-a. Subsurface Geology in Vicinity of Stock Island The parties agree that, as a general proposition, the ground water and surface waters are connected to each other in the Florida Keys. However, no evidence was presented showing a specific location or locations where ground water connects to surface waters. Although it generally is undisputed that, at some point, ground water connects to surface waters, the parties disagree regarding whether, where, and how long it may take for the injected effluent to reach surface waters. Petitioners contend that due to the local geology, the injected effluent from the Existing Wastewater Facility rapidly reaches surface waters in the vicinity of Stock Island and that the increased discharge through the new injection wells will exacerbate and cause or contribute to surface water quality violations in the immediate vicinity of Stock Island and offshore. In support of this position, Petitioners presented the testimony of Scott Zednek, a Florida-licensed P.G. Zednek opined that due to the absence of subsurface sediments that would prevent upward flow to surface waters, the buoyant freshwater effluent injected down the wells will rapidly vertically migrate through the highly transmissive Key Largo Limestone and Miami Limestone to reach surface waters. To develop his opinion, Zednek reviewed a Florida Geological Survey boring log ("FGS Log") approximately one-third mile from the Existing Wastewater Treatment Facility and a Universal Engineering Services geotechnical study boring log ("UES Log") performed on the KWRU site. The FGS Log was prepared specifically to analyze the subsurface geology. The UES Log was performed as part of a geotechnical study to analyze subsurface conditions onsite specifically for the purpose of determining the load-bearing capability of the KWRU site to support a concrete water tank. As such, the FGS Log provides a more precise view of the subsurface geology in the vicinity of the KWRU site.36/ Based on the UES Log, Zednek opined that there are no confining layers underlying the KWRU site. The UES Log for the site shows N-values, generated using an ASTM-designated process for determining the resistivity or strength of the subsurface, of between two and 43 for the first 60 feet of sediment below the surface. According to Zednek, an N-value of less than 50 indicates lack of a confining layer. Further, his review of the UES Log did not show the presence of Q-layers, which may function as semi-confining layers, or aquitards, that would substantially restrict the movement of fluid, including the injected effluent.37/ Based on the UES Log, Zednek opined that the limestone underlying the site is fractured, creating vertical pathways for the injected effluent to migrate upward to the surface. Zednek testified that the Key Largo Limestone, into which the effluent is injected, is very porous and highly transmissive, facilitating rapid migration once the effluent is injected. Based on his review of the FGS Log, Zednek testified that a Q-layer first appears at approximately 62 feet below the ground surface——below the depth of the injection wells' casing—— so it would not act as a confining layer for the injected effluent. Zednek further observed that this Q-layer is only 1.5 centimeters thick. In his experience, this thickness is not sufficient to create a confining or semi-confining layer. Zednek thus opined that the subsurface geology at the KWRU site will enable and facilitate vertical migration of the injected effluent to surface waters. Zednek also noted the proximity of the Safe Harbor channel cut. He opined that the injected effluent likely would horizontally migrate through the highly transmissive Key Largo Limestone,38/ then vertically migrate to surface waters through the "path of least resistance" at the Safe Harbor channel cut. As further support for his opinion, Zednek cited an interim report summarizing results of a subsurface dye tracer study performed for the Florida Keys Aqueduct Authority regional wastewater treatment facility. The study's purpose was to determine whether the subsurface geology at the Cudjoe Key location was sufficiently confining to prevent vertical migration of the injected effluent from shallow injection wells proposed at that facility. According to Zednek, the interim report showed that the subsurface at the injection site was not sufficiently confining to prevent the injected effluent from rapidly vertically migrating to surface waters. Petitioners also presented the testimony of John Paul, Ph.D., in support of their contention that the injected effluent from the Expanded Wastewater Facility would rapidly rise through the subsurface limestone up into surface waters. Dr. Paul testified regarding viral tracer studies he had conducted at Long Key, approximately 65 miles east-northeast of Stock Island, and at the Saddlebunch Keys, located approximately 20 miles east- northeast of Stock Island. In conducting these studies, Paul injected bacteriophage viruses into Class V wells and tracked their movement into surface waters. In the Long Key study, the injected viruses moved through the subsurface limestone to the south-southeast and appeared in surface waters in deep canals on the ocean side of U.S. 1 approximately 53 hours after injection. In the Saddlebunch Keys study, the viruses also appeared in surface waters some distance south-southeast of the location at which they were injected.39/ Paul acknowledged that when the viruses appeared in surface waters, they were detected at a concentration of one trillionth (.0000000000001 or 1 x 10-12) less than the concentration in which they had been injected, indicating significant dilution by ground water and/or surface waters. He also acknowledged that canals dredged to depths shallower than the injected depth may not facilitate rapid migration of the injected effluent to surface waters. In rebuttal, KWRU presented the testimony of Michael Alfieri, a Florida-licensed P.G. who specializes in hydrogeology. Alfieri examined the FGS Log and UES Log, and also reviewed the detailed lithology logs and photographs for the FGS Log. Based on his review of this information, Alfieri opined that the FGS Log indicates the presence of semi-confining layers that function as aquitards in the first 60 feet of subsurface sediment. Alfieri noted that the existence of an aquitard depends on the nature of the geologic materials present at that location, so that N-values do not perfectly correlate with the presence or absence of confining layers. Thus, a carbonate silt or clay having an N-value of only two may better function as an aquitard than a porous, transmissive limestone having an N-value of 50, and silts or clays having a thickness as little as one centimeter may function as an aquitard to significantly impede fluid flow.40/ Based on his review of the FGS Log and the detailed lithology log descriptions and photographs for the FGS Log, Alfieri observed four laminated calcrete zones, six Q-zones, and chalky limestone within the first 60 feet——all of which would function as aquitards to impede the vertical movement of the effluent.41/ Thus, according to Alfieri, the effluent is anticipated to migrate laterally from the injection wells below these confining layers before migrating through a vertical pathway to reach surface waters at an unknown location. To predict the likely migration pathway for the effluent, Alfieri conducted hydrological modeling using a simplistic SEAWAT computer model. He used horizontal and vertical transmissivity values for the subsurface strata derived from geological studies previously conducted in the Florida Keys. Although these studies indicate greater horizontal than vertical transmissivity, Alfieri assumed equal vertical and horizontal transmissivity for modeling purposes——necessarily yielding more conservative results than would be anticipated to occur in real life. Accordingly, the modeling results showed more rapid vertical migration than would be anticipated in real life when the Q-zones and calcrete layers depicted in the FGS Log are considered. Even with these conservative assumptions, the modeling results showed the injected effluent migrating horizontally at least a mile offshore42/ before migrating upward to surface waters. The persuasive evidence shows that the injected effluent will be confined to the subsurface and will travel laterally a substantial distance before rising to surface waters at some unknown location or locations offshore. Thus, the credible, persuasive evidence does not support the conclusion that the effluent will rapidly rise to the surface waters in the nearshore area in the vicinity of the KWRU site.43/ Narrative Nutrient Criteria Petitioners allege that the effluent injected down the wells into the ground water will reach surface waters, causing or contributing to a violation of the narrative nutrient criteria for surface waters codified in rules 62-302.530(47)(a) and (b).44/ In support, Petitioners presented the testimony of James Fourqurean, Ph.D., who has extensive experience in research on Florida Keys aquatic ecosystems in their healthy and imbalanced states. Dr. Fourqurean described these ecosystems in their healthy state and in their nutrient-enriched state. Florida Keys nearshore ecosystems normally are oligotrophic, which means they are nutrient-limited. Thus, they do not normally exhibit high chlorophyll-a levels and microalgae counts. When nutrient levels in the Florida Keys ecosystems increase——whether by increasing the concentration of nutrients in discharges or by increasing the volume of water containing nutrients——primary production, i.e., plant growth, increases. Seagrass communities are phosphorus-limited, so that when these communities are exposed to phosphorus-enriched water, the phosphorus is rapidly absorbed from the water column and is stored in the benthos.45/ This phosphorus capture initially leads to increased seagrass abundance, but as phosphorus enrichment continues, the community species composition rapidly shifts to favoring seaweed and microscopic algae, ultimately damaging or destroying the seagrass community. Coral reef communities similarly are nitrogen-limited. Thus, when coral reef communities are exposed to nitrogen- enriched water, they shift to algae-dominated communities——again, damaging or destroying the coral reef communities. Based on historical aerial photographs of the area surrounding Safe Harbor and his experience studying seagrasses in the Florida Keys, Fourqurean concluded that the natural seagrass populations in the entire Florida Keys National Marine Sanctuary area, which includes the Stock Island area, are experiencing ecological imbalance. On the basis of the water quality sampling he conducted in and around Safe Harbor, Fourqurean opined that the imbalance is the result of man-induced nutrient enrichment. However, he did not engage in field studies in and around Safe Harbor, so could not cite specific examples where seagrasses had been replaced by algal-dominated communities in that area. Fourqurean noted that human waste contains high concentrations of phosphorus and nitrogen. In his view, because the effluent from the Existing Wastewater Facility contains phosphorous, it necessarily constitutes a source of phosphorous in the surface waters in Safe Harbor, even though it is injected into ground water. However, he acknowledged the existence of numerous other sources of nitrogen and phosphorus in the Safe Harbor vicinity, including septic tanks, boat cleaning operations and pump outs, and storm water runoff. He further acknowledged that he did not know where or when effluent from the Existing Wastewater Facility (and, by extension, the Expanded Wastewater Facility) may reach surface waters. Fourqurean acknowledged that the Permit at Issue would authorize the injection of effluent treated to AWT standards into ground water, rather than directly to surface waters, and he further acknowledged that the total phosphorus and nitrogen loading from the Expanded Wastewater Facility would substantially decrease as a result of conversion to AWT, even though the volume of effluent discharged down the wells may as much as double. He remained concerned that the Expanded Wastewater Facility may contribute phosphorus——even in very small quantities——to surface waters, causing imbalance to seagrass communities. He also opined that when saline ground water and the fresher effluent mix, the resulting brackish solution would dissolve the calcium carbonate comprising the subsurface limestone, releasing stored phosphorus that would eventually reach surface waters and negatively affect nearshore seagrass communities, However, he acknowledged that depending on subsurface physical conditions and flow paths of the effluent, phosphorous, nitrogen, or both, may be completely removed prior to the effluent reaching surface waters. He further acknowledged that seagrass community health in the Florida Keys National Marine Sanctuary has improved in the last two years and that water quality also has improved, reversing a ten-year decline. This is consistent with replacement of onsite septic tanks by central wastewater treatment systems in the Florida Keys. On rebuttal, KWRU presented the testimony of William Precht, who has extensive experience with Florida Keys geology and aquatic communities. Precht confirmed the existence of numerous sources of significant nutrient enrichment in the Safe Harbor vicinity other than the Existing Wastewater Facility, and noted that these sources must be taken into account when analyzing nutrient enrichment in Safe Harbor. He testified that raw wastewater is particularly deleterious to benthic communities. Thus, connecting wastewater generators that currently use septic tanks to central wastewater treatment systems can significantly improve water quality. Precht observed that Fourqurean's single-day sampling in the Safe Harbor area provided information regarding variability in nutrient concentrations, but characterized Fourqurean's conclusion that the Existing Wastewater Facility was the source of the nutrients as "unscientific" because it was based on supposition rather than on testing. He opined that the limited data set gathered over a one-day period could not reliably identify the source of nutrient enrichment in Safe Harbor. Precht testified that flushing capability is a key influence on nutrient concentration in surface waters. The further from a natural marine environment that water quality testing is performed, the more likely water quality will be poor due to nutrient enrichment from land-based sources. Given the configuration of Safe Harbor, water quality would be poorest in the interior dead-end canals and would steadily improve as one moved into more open water and flushing increased, with the highest water quality in open waters outside the canal system. Precht opined that the presence of noxious benthic plant life in the Safe Harbor vicinity may be attributable the destruction of seagrass communities in the area by historical dredging, rather than due to nutrient enrichment. Based on the reduction in total nitrogen and total phosphorus loading as a result of implementing AWT, Precht opined that the proposed discharge will not negatively affect the biological communities in the Safe Harbor vicinity. He further opined that due to the rapid uptake of phosphorus in the marine environment and due to denitrification that occurs in ground water and in marine surface waters, there is little chance that any nutrient loading that may result from the injected effluent would cause damage to the coral reef environment. Also on rebuttal, Alfieri persuasively testified that although phosphate release does occur when freshwater is injected into limestone that formed in a saline environment, this process gradually occurs over "geologic time"——that is, over millions of years. Therefore, he did not anticipate a significant release of phosphate from the subsurface limestone as a result of the effluent discharge. Also, limestone rapidly absorbs phosphorous, so phosphorus in the injected effluent would be absorbed quickly by the subsurface limestone.46/ Further, in any event, the effluent will be diluted by at least seven orders of magnitude——that is, one hundred millionth (.00000001)——of the injected concentration by the ground water, and/or by surface waters (assuming the effluent eventually reaches surface waters). As discussed above, the Keys RAP was prepared in 2008 and updated in 2011. The Keys RAP prescribes specific management activities to be implemented to restore surface water quality in the Florida Keys, including eliminating cesspits and onsite septic tank systems and connecting wastewater generators to centralized wastewater systems that treat the wastewater to AWT standards. Pursuant to the Impaired Waters Rule and DEP's adoption of the Keys RAP, activities that are consistent with the Keys RAP are considered to provide reasonable assurance that the narrative nutrient criterion in rule 62-302.530(47)(b) will be met. As discussed above, the Project will expand a centralized wastewater treatment plant that will accept, and treat to AWT standards, wastewater generated by development on Stock Island——including development that currently relies on onsite septic tanks for wastewater disposal. The Project is consistent with the Keys RAP, so there is reasonable assurance that the Project will meet the narrative nutrient criterion in rule 62-302.530(47)(b). The persuasive evidence shows that the Project will not cause or contribute to alterations of nutrient concentrations in water bodies so as to cause an imbalance in natural populations of aquatic flora or fauna. Thus, Petitioners failed to show that the Project will cause or contribute to violation of the narrative nutrient criterion in rule 62-302.530(47)(b). Further, for the reasons discussed below, it also is determined that the Project will not violate the narrative nutrient criterion codified at rule 62-302.530(47)(a). Numeric Nutrient Criteria Petitioners also allege that the effluent will cause or contribute to violation of the estuary-specific numeric interpretations of the narrative nutrient criteria for the Back Bay nutrient region, codified at rule 62-302.532(1)(g)1., and the Lower Keys nutrient region, codified at rule 62-302.532(1)(g)3. In support, Petitioners cite the results of surface water sampling performed by Fourqurean in the Safe Harbor area showing high levels of nitrogen, phosphorus, and chlorophyll-a. Petitioners contend that these high nutrient levels evidence that the existing injection wells already are causing or contributing to surface water quality violations in the waters surrounding Stock Island, and that the increased effluent discharge from the proposed new injection wells will exacerbate this situation, further causing or contributing to violations of surface water quality standards. In preparing his opinion regarding the effect of the proposed injection wells on surface water quality, Fourqurean sampled surface water quality on one day at nine stations located in the vicinity of Stock Island, ranging from shallow waters inside the Safe Harbor basin to deeper waters offshore. Samples were collected at the surface and at a depth of one meter below the surface following the standard operating procedures for water quality sampling established by the Florida Keys Water Quality Protection Program. Fourqurean testified that the samples collected at the stations inside the Safe Harbor basin and near the shore of Stock Island showed very high levels of chlorophyll-a, evidencing that these areas are dominated by microalgae and, thus, are eutrophic. Additionally, the samples collected inside the Safe Harbor basin exhibited very high phosphorus concentrations—— almost three times greater than the estuary-specific numeric nutrient criterion for phosphorus. Phosphorus concentrations correspondingly decreased as samples were collected outside of the basin and offshore. Nitrogen concentrations followed a similar pattern in the sampling that Fourqurean conducted inside and outside of the Safe Harbor basin. According to Fourqurean, the high nutrient concentrations in the samples taken in Safe Harbor, when compared to the lower concentrations in samples taken outside of Safe Harbor, evidence the existence of a large source of phosphorous and nitrogen in Safe Harbor——in his view, the Existing Wastewater Facility. However, Fourqurean acknowledged that there are many potential nutrient enrichment sources on Stock Island, including fishing operations, boat sewage pump-outs, and direct discharges of storm water to surface waters. He further acknowledged that the specific source of phosphorus and nitrogen in the surface waters surrounding Stock Island cannot be identified. He did not opine as to the relative amounts of nutrients in surface waters that he believes are being contributed by the Existing Wastewater Facility or that will be contributed by the Expanded Wastewater Facility, as compared to other nutrient sources in the Safe Harbor area. He also acknowledged that a scientifically-valid water quality study would require more than a single day of sampling.47/ Kenneth Weaver, environmental administrator for DEP's Standards Development Section,48/ credibly and persuasively testified, and the water quality data for nutrients and chlorophyll-a collected in the WBIDs surrounding Key West and Stock Island show, that the surface waters in these WBIDs meet the applicable NNCs.49/ Historical water quality data also show that since 2008, the surface waters in these WBIDs continuously have met the baseline concentrations on which the NNCs were established and adopted. Even with the increased volume of wastewater treated by the Expanded Wastewater Facility, implementation of the AWT standard by the facility's wastewater treatment trains will substantially reduce the amount of total nitrogen and total phosphorus discharged into ground water through the injection wells. Specifically, for total nitrogen, the concentration will be reduced from 13.92 mg/L to 2.25 mg/L, and the total amount of nitrogen loading will be reduced from 58 to 15.9 pounds per day, representing a total net reduction of 72.4 percent in the discharge of total nitrogen. For total phosphorus, the concentration will be reduced from 3.47 mg/L to .75 mg/L, and the total amount of phosphorus loading will be reduced from 14.4 to 5.3 pounds per day, representing a total net reduction of 63.3 percent in the discharge of total phosphorus.50/ Weaver addressed the effects of these projected nutrient discharge concentrations on the surface waters in WBIDs 8074 and 8079, which comprise the portions of the Lower Keys Region and Back Bay Region closest to the KWRU site. He opined that, because these regions are currently meeting the applicable NNCs for nitrogen and phosphorus, and because KWRU's implementation of AWT will result in substantial reduction of total nitrogen and phosphorus loading, the NNCs will continue to be met in these regions——even in a "worst-case" scenario that assumes all of the treated effluent from the Expanded Wastewater Facility is disposed of through the injection wells and reaches the surface. The persuasive evidence shows that the Project will not cause or contribute to violations of the applicable numeric nutrient criteria. Thus, Petitioners failed to show that the Project will cause or contribute to violation of the applicable numeric nutrient criteria in rule 62-302.532(1)(g)1. and 3. Surface Water "Free-From" Standards Petitioners allege that the effluent contains iron and copper above detection limits, as well as personal care products and pharmaceuticals, and that these constituents violate rules 62-302.500(1)(a)5. and 62-302.530(61). Rule 62- 302.500(1)(a)5. requires all surface waters of the state to be free from domestic, industrial, agricultural, or other man- induced non-thermal components of discharges which, alone or in combination with other components of discharges (whether thermal or non-thermal), are present in concentrations which are carcinogenic, mutagenic, or teratogenic to human beings or to significant, locally occurring wildlife or aquatic species, unless specific standards for such components are established by rule. Rule 62-302.530(61) effectively requires surface waters to be free from substances in concentrations which injure, are chronically toxic to, or produce adverse physiological or behavioral response in humans, animals, or plants. These rules collectively comprise the "free-from" standards for surface waters. Petitioners presented no evidence to substantiate the allegation that the effluent from the Expanded Wastewater Facility will contain pharmaceuticals or personal care products. However, even assuming these constituents were present in the effluent, Petitioners did not present evidence showing that they are carcinogenic; mutagenic; or teratogenic to human beings or to significant, locally occurring wildlife or aquatic species; or that they are injurious or chronically toxic to, or produce adverse physiological or behavioral response, in humans, animals, or plants. Petitioners did not present evidence showing that the effluent contains copper and iron in quantities that violate any applicable surface water quality standards, including the surface water "free-from" standards. Paul testified, based on sampling he conducted at domestic wastewater outfalls discharging directly to surface waters, that effluent treated to AWT standards often contains pathogenic bacteria and viruses that constitute threats to human health. On this basis, he opined that even though the effluent from the Expanded Wastewater Facility is treated to AWT, it may contain pathogenic constituents that are harmful to human health. However, as previously discussed, the evidence shows that the effluent discharged through KWRU's injection wells will be substantially diluted by groundwater, and also by surface waters to the extent it reaches surface waters at some unknown location. Accordingly, the results of Paul's pathogen studies cannot be extrapolated to conclude that KWRU's effluent also will contain pathogenic bacteria and viruses in such amounts as to constitute a threat to human health. Petitioners failed to show that the effluent disposed of in the injection wells will cause or contribute to violations of the surface water quality standards in rules 62- 302.500(1)(a)5. and 62-302.530(61). Dilution to Meet Surface Water Quality Standards Petitioners allege that KWRU is relying on dilution of the effluent in order to meet surface water quality standards without having been permitted for a mixing zone, in violation of rule 62-302.500(1)(c).51/ This contention lacks merit. As discussed in detail above, the credible, persuasive evidence establishes that the effluent discharged through the injection wells will not violate water quality standards for and parameters, including for nutrients, and will not cause or contribute to the violation of water quality standards. The credible, persuasive evidence establishes that once injected, the effluent will horizontally migrate a considerable distance before it may migrate vertically to reach surface waters. The parties generally agree that ground water and surface waters are "connected" in the Florida Keys. To that point, although it appears likely that at some point the effluent will reach surface water, the evidence does not establish that is an absolute certainty. Nonetheless, even assuming the effluent would reach surface waters at some unknown location and time, the persuasive evidence shows that it would be so substantially diluted by the ground water that it would neither cause nor contribute to violations of surface water quality standards. Further, the persuasive evidence, consisting of Weaver's "worst case" analysis of nutrient loading from the effluent discharge, which assumed no dilution by ground water, establishes that even if the effluent——which will be treated to AWT standards——were discharged directly into surface waters, it would meet the applicable nutrient criteria. Finally, Petitioners' claim assumes that the effluent will be discharged into surface waters. However, as discussed above and in greater detail below, to the extent the effluent ultimately may be discharged to surface waters, such discharge would be indirect, so would not be subject to statutory and rule provisions requiring establishment of a mixing zone. For these reasons, Petitioners failed to prove that KWRU violated any applicable law or rule by not requesting and obtaining a mixing zone for the discharge of the effluent through the injection wells. Class V Injection Wells in Monroe County Petitioners also allege that issuance of the Permit at Issue violates rule 62-528.630(7), which requires all Class V Group 3 domestic wastewater injection wells in Monroe County to provide reasonable assurance that operation of the well will not cause or contribute to a violation of surface waters standards as defined in chapter 62-302. As discussed above, the credible, persuasive evidence establishes that the operation of the wells as authorized under the Permit at Issue will not cause or contribute to violations of surface water quality standards codified in chapter 62-302. Accordingly, Petitioners failed to prove that the Permit at Issue should be denied on the basis that it violates rule 62-528.630(7). Antidegradation Petitioners contend that the Permit at Issue must be denied because KWRU failed to provide reasonable assurance that the injection of effluent will not violate the antidegradation requirements applicable to surface waters codified at rules 62- 4.242, 62-302.300, 62-302.530(47)(a), and 62-302.700(1). This contention lacks merit. As more fully discussed below, the antidegradation requirements in these rules apply only to a direct discharge to surface waters, which is not present in this case. Here, the evidence clearly establishes that the injection wells do not directly discharge effluent into surface waters. It is undisputed that the effluent will be injected from the wells into Class III ground water, where it will migrate through the subsurface strata. Although it is likely that, due to a "connection" between ground water and surface waters, the effluent ultimately will reach surface waters at some unknown location or locations at some unknown time, this constitutes an indirect discharge, which is specifically excluded from the term "discharge of a pollutant." Fla. Admin. Code R. 62-620.200(13). However, even if the antidegradation rules did apply to the discharge of the effluent through the injection wells, Petitioners failed to prove that the discharge would degrade surface waters. As discussed above, the credible, persuasive evidence establishes that the surface waters in the Florida Keys, including those in and around Stock Island and Key West, currently meet the narrative and/or nutrient criteria, as applicable, and that effluent discharged through the injection wells will be treated to AWT standards, substantially reducing the facility's total nutrient loading below current levels. Thus, the credible, persuasive evidence established that, even in a "worst-case" scenario, which assumes no dilution of the effluent by ground or surface waters, the effluent still would not cause or contribute to a violation of the narrative or numeric nutrient criteria. As discussed above, the credible, persuasive evidence showed that, in fact, the effluent will be very substantially diluted by the ground water into which it is injected, and will be further diluted if and when it ultimately reaches surface waters. For these reasons, Petitioners failed to prove that KWRU did not provide reasonable assurance that the disposal of the effluent through the injection wells would not degrade surface waters, in violation of rules 62-4.242, 62-302.300, 62- 302.530(47)(a), and 62-302.700(1). Alleged Violation of Ground Water Standards Petitioners allege that KWRU did not provide reasonable assurance that the injection wells would not violate applicable ground water standards. Petitioners further allege that there is an underground drinking water source under Stock Island. In that case, more stringent ground water quality and injection well rule standards would apply to operation of the injection wells. Petitioners did not present any credible, persuasive evidence to support these allegations. The persuasive evidence establishes that although there is a fresh water lens under Stock Island, it is not classified as an underground source of drinking water52/ due to its substantial variability in horizontal and vertical extent, which renders the salinity levels highly variable. Thus, the ground water at Stock Island is classified as Class G-III ground water which is non-potable ground water having a total dissolved solids content of 10,000 mg/L or greater, or having a total dissolved solids content of 3,000 to 10,000 mg/L and having been determined to have no reasonable potential as a future source of drinking water or designated by rule as an exempted aquifer. Only the minimum criteria for ground water, known as the "free-from" standards, apply to Class G-III ground water. Fla. Admin. Code R. 62-520.430(1). These criteria require that at all times and in all places, ground water be free from discharge components in concentrations that are carcinogenic, teratogenic, mutagenic, or toxic to humans; acutely toxic within surface waters affected by ground water; pose a serious danger to the public health, safety, or welfare; create or constitute a nuisance; or impair the reasonable and beneficial use of adjacent waters. Fla. Admin. Code R. 62-520.400. There is no evidentiary basis on which to infer that the effluent from Expanded Wastewater Facility that is disposed through the injection wells will violate the free-from standards KWRU's many years of effluent monitoring at the Existing Wastewater Facility show that the effluent does not violate these standards. Further, David Rhodes, a Florida-licensed P.G. employed by DEP, credibly testified that a violation of the free- from standards necessarily would entail the presence of toxic materials in KWRU's effluent and that there would be immediate and dramatic effects on the flora and fauna at the golf course, where reclaimed water is reused for irrigation. Since such effects never have occurred, it is reasonable to infer that the effluent from the Expanded Wastewater Facility will not violate the free-from standards.53/ Additionally, as previously addressed, the credible, persuasive evidence demonstrates that no surface water quality violations will result from installation and operation of the injection wells as part of the Expanded Wastewater Facility. Accordingly, the reasonable and beneficial use of adjacent waters will not be impaired due as a result of the injection wells. Petitioners also claim that due to inadequate treatment by the Expanded Wastewater Facility, the effluent disposed in the injection wells will contain unacceptably high levels of bacteria and viruses. The persuasive evidence establishes that KWRU provides high-level disinfection prior to injecting the effluent or sending the reclaimed water for reuse at the golf course. Historical monitoring data shows that KWRU's effluent complies with applicable microbial standards, and unrebutted evidence consisting of quality-related beach closure data for the Florida Keys, gathered as part of the Department of Health's Healthy Beaches monitoring program, indicates that no beach closings in the Florida Keys ever have been attributed to KWRU's Existing Wastewater Facility. Petitioners did not prove that KWRU failed to provide reasonable assurance that operation of the injection wells authorized as part of the Project will not result in violations of applicable ground water standards. To the contrary, KWRU provided reasonable assurance that the effluent from the Expanded Wastewater Facility disposed in the injection wells authorized as part of the Project will not violate any applicable ground water standards. Alleged Water Quality Violations Due to Reuse System Petitioners allege that KWRU did not provide reasonable assurance that the storage of up to 1 MGD of reclaimed water in the reuse system storage ponds on the Key West Golf Club golf course will not cause or contribute to a violation of surface water quality standards and ground water standards. Specifically, Petitioners posit that, because the ponds are unlined, reclaimed water from the Expanded Wastewater Facility will leach from the ponds into the ground water and reach surface waters, violating surface water quality standards and ground water standards and negatively impacting human health through high levels of microbial pathogens, pharmaceuticals, and personal care products. Petitioners further allege that discharge of reclaimed water from the ponds into the ground water could mobilize constituents of concern from the Key West Landfill and a closed waste-to-energy facility, both of which are near the golf course, ultimately resulting in surface water quality standards and ground water violations. In support of these contentions, Petitioners presented the testimony of Scott Zednek, who testified that the reclaimed water, which is fresher than the surrounding ground water, may leach from the ponds into the ground water, and thereafter potentially may reach surface waters. According to Zednek, this leaching could occur because the ponds are unlined. Additionally, Zednek opined that, because there is a closed landfill near the golf course, the reclaimed water leaching from the reuse system ponds could mobilize and spread contaminants from the landfill. The persuasive evidence demonstrates that storage of the reclaimed water in the reuse system ponds will not result in violations of ground water standards or surface water quality standards. Although the golf course ponds are unlined in the sense that a high-density polyethylene or impermeable clay liner has not been installed on the bottom and sides of the ponds, over the years, marl has formed on the bottom and sides of the ponds, creating an aquitard that substantially confines the reclaimed water to the ponds, rather than allowing it to readily leach into the ground water. Further, the reclaimed water generally is less saline than the ground water underlying the course, so tends to "float" on top of, rather than readily mixing with, the denser, more saline ground water. Additionally, the evidence shows that years of historical ground water monitoring data obtained through monitoring wells on the golf course near the reuse system ponds showed no ground water standards violations as a result of storing reclaimed water from KWRU in the ponds.54/ Because the amount of reclaimed water being sent to the reuse storage ponds is not being changed by the Project, and the nutrient levels in the reclaimed water are being through AWT, there is no factual basis from which to infer that storage of the reclaimed water in the pond will result in violations of ground water standards or surface water quality standards. The persuasive evidence also does not support Zednek's view that reclaimed water leaching into the ground water from the storage ponds will mobilize pollutants under the nearby landfill. As discussed above, the persuasive evidence establishes that, due to the aquitard, there will be very little leaching of reclaimed water into the ground water, and even if such leaching did occur, there would be very little mixing of the reclaimed water with the more saline ground water. As such, there is no demonstrated factual basis on which to infer that reclaimed water will flow under, and mobilize and spread pollutants from, the landfill. Further, the evidence establishes that the predominant ground water flow direction under Stock Island is to the south- southeast. Since the landfill is located north of the reuse system ponds, any reclaimed water that did enter ground water would flow south-southeast, away from the landfill. Zednek also opined that if the storage ponds overflowed, the reclaimed water could run off into surface waters, resulting in surface water quality violations. However, the evidence establishes that KWRU will only send as much reclaimed water to the reuse storage ponds as the Key West Golf Club requests, so any assertion that the ponds will overflow is speculative. Further, even if the ponds were to overflow, Petitioners did not show that the reclaimed water would flow into surface waters, or that it would violate surface water quality standards if it were to flow into surface waters. Petitioners did not prove that KWRU failed to provide reasonable assurance that the storage of reclaimed water in the reuse system storage ponds at the Key West Golf Club will not violate any ground water standards. Stated another way, KWRU provided reasonable assurance that the storage of reclaimed water in the reuse system ponds at the Key West Golf Club golf course will not cause or contribute to violations of ground water standards or surface water quality standards. Applicability of AWT to Existing Wastewater Facility Commencing January 1, 2016, the two new treatment trains authorized by the Permit at Issue must meet the AWT standards. These treatment trains are authorized to treat wastewater to specified secondary standards through December 31, 2015. Petitioners assert that the Permit at Issue must be denied because the two new treatment trains should be required to meet AWT standards immediately upon operation, and that allowing the new treatment trains to meet secondary standards through December 31, 2015, violates section 403.806(10) and rule 62- 620.620(4). Sections 403.086(10)(c) and (d) expressly impose the AWT standards on all new or expanded domestic wastewater discharges after December 31, 2015. Accordingly, the Permit at Issue is completely consistent with the statute. Further, the Permit at Issue does not violate rule 62- 620.602(4). That rule requires a wastewater facility permit applicant to make certain specified demonstrations when a permit is renewed, revised, or reissued having a less stringent effluent limitation than contained in a previous permit. Although the Existing Permit states that the Existing Wastewater Facility has been modified to meet the AWT standards, it further states: "[t]he extended aeration process will be switched to the AWT nutrient removal system prior to January 1, 2016." The clear import of this statement is that the AWT standards are not required to be met until January 1, 2016, consistent with section 403.806(10). Because the Permit at Issue also requires the new treatment trains to meet the AWT standards commencing on January 1, 2016, the Permit at Issue does not impose a less stringent effluent limitation than that imposed by the Existing Permit; accordingly, KWRU is not required to make the so-called "anti-backsliding" demonstrations set forth in rule 62- 620.620(4). Furthermore, it is undisputed that the new treatment trains will not be constructed and operational before January 1, 2016; thus, as a practical matter, the new treatment trains must meet the AWT standards immediately upon going into operation. Thus, Petitioners have not shown that the Permit at Issue should be denied on the basis that it violates section 403.806(10) and rule 62-620.620(4). Petitioners' Standing As noted above, Petitioner Halloran, resides in Key West, Florida. His residence fronts on the water and he owns a boat. Halloran and his family use and enjoy the waters around Key West for swimming, fishing, kayaking, and other in-water recreational uses, eat local-caught seafood, and engage in nature photography. Halloran also owns rental properties that front on the water, and he owns and rents out dock space for houseboat mooring. He is a member of Last Stand. Halloran has challenged the Permit at Issue because he is concerned that the increased discharge of effluent from the Project down the injection wells will degrade the waters around Key West where he and his family engage in in-water recreational uses. He also is concerned that the increased effluent discharge, particularly nutrients, will harm the seagrasses, coral reefs, and the benthic communities in the waters around Key West. Halloran read the initial petition prepared and filed in this proceeding, and he skimmed the Amended Petition specifically to determine the changes from the initial Petition.55/ He acknowledges that he does not completely recall the entire contents of the initial petition or the Amended Petition. Petitioner Last Stand is a not-for-profit corporation incorporated under Florida law. Naja Girard D'Albissin, a member of the Board of Directors of Last Stand, appeared on behalf of Last Stand. D'Albissin testified that Last Stand currently has approximately 105 members. Last Stand's mission is to promote, preserve, and protect the quality of life in Key West and the Florida Keys, with particular emphasis on protecting the natural environment. Last Stand historically has engaged in environmental advocacy directed toward governmental entities and engaged in litigation opposing activities that its members believe would harm the natural environment. In July 2014, Last Stand's Board of Directors voted to challenge the Permit at Issue. Respondent DEP stipulated that 52 members of Last Stand spend time or reside in Monroe County, 50 members enjoy the waters and natural environment of the Florida Keys, and 50 members believe that their use and enjoyment of the natural environment and economic interests in Monroe County will be adversely affected by the Project. Last Stand tendered, for admission into evidence, affidavits of some of its members attesting to the substantial interests they contend will be injured by the Project. However, Last Stand had refused to allow Respondents to engage in discovery regarding these members' alleged substantial interests; accordingly, the undersigned did not allow these members to testify at the final hearing.56/ The affidavits were excluded from admission into evidence as unsupported hearsay. See § 120.57(1)(c), Fla. Stat. Entitlement to Permit at Issue KWRU met its burden under section 120.569(2)(p) to present a prima facie case demonstrating entitlement to the Permit at Issue by entering into evidence the applications and supporting materials for the Permit at Issue for the Project. Additionally, KWRU presented persuasive, competent, and substantial evidence beyond that necessary to meet its burden under section 120.569(2)(p) to demonstrate its entitlement to the Permit at Issue. Petitioners did not meet their burden of persuasion under section 120.569(2)(p) in this proceeding to demonstrate that the Project does not meet all applicable statutory and rule requirements. Furthermore, on rebuttal, KWRU and DEP thoroughly addressed and rebutted the grounds that Petitioners allege justify denial of the Permit at Issue. The persuasive evidence demonstrates that the Project meets all applicable statutory and rule requirements. Accordingly, KWRU is entitled to issuance of the Permit at Issue.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Protection enter a final order approving the issuance of Domestic Wastewater Facility Permit FLA014951-012-DWIP and UIC Permits 18490-020 and 18490-021. DONE AND ENTERED this 15th day of January, 2016, in Tallahassee, Leon County, Florida. S CATHY M.

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.
