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

Findings Of Fact The parties stipulated, and it is so found, that Petitioner, DER, has jurisdiction over both the issues and the Respondents Dey and KWC. KWC owns and operates a water system which supplies water to both residential and commercial customers in the City of Keystone Heights, Florida. Virginia Key is the President of KWC, a member of the Board of Directors of the corporation, and one of the five stockholders. The other stockholders are her sisters. The five sisters are the daughters of the late G. E Wiggins, and inherited the company from him at his death in 1969. Mr. Wiggins developed the water company in the 1920's and operated it until his death. KWC came under the jurisdiction of the Florida Public Service Commission (PSC) just prior to Mr. Wiggins' death. At that time, pursuant to a PSC requirement, it was assessed and valued at a sum in excess of $250,000.00 by a consultant firm hired for the purpose. As of late November, 1984, KWC served approximately 752 residential customers which, when multiplied by an average 2.5 persons per family factor, results in a total of approximately 1,880 residential inhabitants served by the water system. In addition, the system serves 105 commercial customers. It is impossible to estimate with any reasonable degree of accuracy the number of individuals involved in the commercial service. The system consists of three wells drilled in 1940, 1946, and 1960 to a depth of 350, 450, and 492 feet respectively. Total yield from the three wells is normally 1,350 gallons per minute. The wells are generally well protected against surface water infusion, are normally not subject to inundation, and have had no salt water infiltration problems in the past. At the present time, well number 2, drilled in 1946, with a 350 gpm yield is out of service. The water, when pumped from the ground, is stored in two tanks-one with a 60,000 gallon capacity and the other with a capacity of 800 gallons. Both tanks are steel. Chlorine is added to the water in each storage situation by a hyper-chlori- nation system before the water is sent to the storage tank. The distribution system is made up of 6" and 2" diameter pipe. In March, 1984, two different inspections of the water system, done by, in one case, an environmental specialist and in the other, an Engineer I with DER, revealed several deficiencies in the maintenance and operation of the system all of which constitute violations of DER rules. Specifically, these include (1) failure to provide an auxiliary power source in the event the main pumping capability of the system is lost, (Rule 17-22.106 (3)(a); (2) failure to utilize for the system an operator certi- fied by the state with a Class C license, (Rule 17-22.107(3)(b); (3) failure to maintain a free chlorine residual in the water of at least 0.2 ppm in the system, (Rule 17-22.106(3)(c); (4) failure to maintain a minimum pressure of 20 ppi in the distribution system, (Rule 17-22.106(3)(f); (5) failure to have a gas chlorination facility, (Rule 17-22.106(3)(d); and (6) failure to obtain proper permits to expand the distribution system, (Rule 17-22.108 (1)(b) Rule 17-22, F.A.C., sets up requirements for safe drinking water and was designed to establish guidelines and standards for facilities and water and to bring water into compliance with the Federal Act. Twenty ppi of pressure in the system was adopted as a standard minimum for residual pressure to protect against outside contaminants getting into the water system. Such contaminants could come from ground water, leaks, and water in storage tanks attached to the system such as toilet tanks, being aspirated into the system. Also a certain amount of pressure is required to operate appliances. Normally minimum pressure is found in areas at the edge of the system and in those areas where inadequate chlorination is located. They interact and both pressure and chlorinization are required. Chlorine can be injected into the system generally in two ways: the first is through gas chlori- nation and the second, through hyper-chlorinization as is used in the instant system. The effectiveness of hyper-chlorinization is limited, however, by the size of the system. Basically, hyper- chlorinization is effective when the demand in the system for pressure is no more than 10 ppi. Above this, gas chlorinization is necessary. As late as January 4, 1985, Mr. Dykes went to Keystone Heights to test the system. His tests showed that 11.9 ppi is the average daily flow per 24 hours for the last 12 months. Since this figure is above 10 ppi, in his opinion, a gas chlorinization system would be needed. Chlorine is used to purify water because it has been shown, through long use, to prevent disease. The requirement for a residual chlorine level in water, therefore, is consistent with that concept to insure chlorine is always in the water in sufficient quantity to prevent disease. Respondent's plant has less than the 0.2 residual that is required under the rule. This insufficiency is caused by the inadequate chlorinization system which has insufficient capacity to provide the appropriate amount of chlorine. At the current level, it is providing only approximately 60 percent of the needed chlorine. To correct this deficiency Mr. Dykes recommends installation of a gas chlorinization system. In addition, the pneumatic tank storing the water from the number 3 well does not give sufficient detention time to allow for appropriate reaction of the chlorine contained in the water before the water is released into the distribution system. Another factor relating to the lack of adequate pressure in the system is the fact that, in Mr. Dykes' opinion, too much of the system is made up of 2" diameter water line. A line of this small diameter prevents the maintenance of adequate pressure especially in light of the fact that there are numerous old lines in the system some with corrosion and scale in them which tends to reduce pressure. This latter factor would be prevalent even in the 6" lines. The current plant manager, Mr. Cross, who has been with Respondent for approximately 4 years is, with the exception of one part time employee, the only operations individual associated with the plant. As such, he repairs the meters and the lines, checks the pumps, the chlorinator, and checks and refills the chlorine reservoir on a seven day a week basis. Be learned the operation of the plant from his precedessor, Mr. Johnson, an unlicensed operator who was with the company for 10 years. Mr. Cross has a "D" license which he secured last year after being notified by DER that a license was required. It was necessary for him to get the "D" license before getting the required "C" license. At the present time, he is enrolled to take courses leading toward the "C" license. At the present time, however, he is not, nor is anyone else associated with KWC, holding a license as required. The rule regarding auxiliary power provides that all community systems serving 350 or more persons shall have standby pumping capability or auxiliary power to allow operation of the water treatment unit and pumping capability of approximately one-half the maximum daily system demand. Respondent has admitted that the system is not equipped with an auxiliary power source and it has already been established that more than 350 persons are served by the system. Respondent also admits that subsequent to November 9, 1977, it constructed main water lines for the system which required the obtaining of a permit from either the Petitioner or the county health unit. Respondent admits that it did not obtain or possess a permit to do the additional construction referenced above from either DER or the Clay County Health Department prior to the construction of the water lines referenced. The inspections referenced above, which identified the problems discussed herein, were accomplished by employees of Petitioner, DER, at a stipulated cost of $898.10. Respondent contends, and there is no evidence to the contrary, that there have been no complaints of contaminated water and that the monthly water samples which Mr. Cross forwards to the Clay County Health Department have been satisfactory. Mr. Cross also indicates that a September, 1983 DER analysis of water samples taken from the system was satisfactory. However, bacteriological analysis reports on water collected from Respondent's system on July 11 and 27, 1983, reflect unsatisfactory levels of either coliform or non-coliform bacteria in the water requiring resubmission of test samples. Respondent also contends that no one has ever gotten sick or died from the water furnished by the system and there is, in fact, no evidence to show this is not true. Even though so far as is known, no one has ever been made sick from the water in the system, in Mr. Dykes' opinion, the risk is there. As a result of the defects identified in this system, insufficient chlorine is going into the system to meet reasonable health standards. Though this does not mean that the water is now bad, it does mean that at any time, given a leak or the infusion of some contaminant, the water could become bad quickly, and the standard established by rule is preventive, designed to insure that even in the case of contamination, the water will remain safe and potable. Respondent does not deny that it is and has been in violation of the rules as set out by the Petitioner. It claims, however, that it does not have sufficient funds available to comply with the rules as promulgated by DER. Respondent has recently filed a request for variance under Section 403.854, Florida Statutes, setting forth as the basis for its request that it does not have the present financial ability to comply with any of the suggested or recommended corrective actions to bring its operation into compliance with the rules. Mr. Protheroe, the consulting engineer who testified for Respondent has not evaluated the system personally. His familiarity with it is a result of his perusal of the records of the company and the Petitioner. Based on his limited familiarity with the system, he cannot say with any certainty if it can be brought into compliance with, for example, the 20 ppi requirement. There are too many unknowns. If, however, the central system was found to be in, reasonably good shape, in his opinion, it would take in excess of $100,000.00 to bring it within pressure standards. To do so would require replacement of the 2" lines, looping the lines, and cleaning and replacing some central system lines as well. In his opinion, it would take three months to do a complete and competent analysis of the system's repair needs. Once that was done, he feels it would take an additional three months to bring the plant into compliance with DER requirements. Other repairs, such as those to the lines outside the plant, would take longer because some are located in the downtown area and have interfaced with other utilities. This could take from three to four months if the money were available to start immediately. Here, however, it has been shown that it is not. Consequently, to do the study and then, if possible, procure the funds required, could take well in excess of six months or so. Mr. Protheroe contends, and there is little if any evidence to indicate to the contrary, that to replace the current system with a new one entirely as it is currently constituted would cost at least $250,000.00. However, in his opinion, no one would ever put in a new system similar to the one currently there. He cannot say how much it would cost to buy the system and make the necessary corrections to it to rectify the deficiencies. His familiarity with the system is not sufficiently complete to do this. He cannot say exactly how much the system is worth in its current state, but he is satisfied that it is worth more than $65,000.00. In that regard, Mrs. Dey indicated that in her opinion, the fair market value of the system is currently at $250,000.00. At the present time, there are current outstanding loans in excess of $9,000.00 at 16 percent interest. This current loan basis has been reduced from a higher figure. In 1977, the company borrowed $15,000.00 at 9 percent. In 1981, it borrowed $5,000.00 more at 18 percent. In 1982, the loans were consolidated at an increased rate of 16 percent and the officers have been advised by their current creditors that they cannot borrow any more money for the system in its current state. They would sell the system if a reasonable price could be realized. However, any inquiries on prospective purchases have been chilled by a low rate base assigned by the PSC. In that regard, the City of Keystone Heights offered to purchase the system for $59,000.00. This offer was declined as being unreasonable. Nonetheless, in light of the low rate base assigned by the PSC in its order issued on December 21, 1981 of slightly over $53,000.00 the offer by the city of $59,000.00 is not completely out of line. A certified public accountant, in KWC's December 31, 1983 financial report assigned a valuation of approximately $62,000.00, again a figure only slightly higher than that offered by the city, but substantially less than the $175,000.00 price asked of the city by Respondent Dey and her sisters. Mrs. Dey indicated that to the best of her knowledge the PSC denied rate increases for the purposes of improvements. In the presentation before the commission, respondents relied exclusively on the services of their attorney and accountant. Evidence from Mr. Lowe, of the PSC, however, indicates that KWC has never requested a rate increase to finance any of the improvements called for here. In the PSC order referred to above, Respondent was awarded a 12.25 percent rate of return on its rate base. This figure was an amalgam of a more than 13 percent rate on equity and a lesser figure for cost of doing business, including debt. At the time of that hearing, however, the debt cost was based on a 9 percent interest figure. The 16 percent interest figure came afterwards and no hearing has been requested based on the higher interest rate and it is so found.
Recommendation Based on the foregoing findings of fact and conclusion of law, it is, therefore: RECOMMENDED that Respondents Virginia W. Day and the Keystone Water Company be ordered to comply with the Orders for Corrective Action previously filed herein to bring the water system in question in compliance with the Florida Safe Water Drinking Act without delay or suffer the penalties for non- compliance called for by statute and, in addition, pay costs of investigation in the amount of $898.16. RECOMMENDED in Tallahassee, Florida this 19th day of February, 1985. ARNOLD H.

Findings Of Fact On July 5, 1978, Gulfside applied to DER for the issuance of a permit to operate a wastewater treatment plant on property owned by it on Perdido Key in Escambia County, Florida. The proposed plant is designed to serve a condominium complex consisting of 64 units, with the expectation that 350 gallons of water per day per unit will be discharged into the system, thus requiring a minimum plant capacity of 22,400 gallons per day. The plant described in the application has a capacity to handle 24,000 gallons per day. The proposed plant will use an extended aeration process whereby effluent is routed from the individual units through a filter within the proposed plant and then discharged into two percolation ponds associated with the facility. The plant is designed to remove 90 percent of B.O.D. and suspended solids. In addition, the plant is designed with duplex blowers and pumps to insure continued operation in the event of failure of one of the units. An emergency generator is included to provide back-up power for the entire plant, including blowers, pumps and chlorinators. Perdido Key, where the proposed plant is to be located, is a barrier island located off the coast of Escambia County, Florida, near the Florida- Alabama border. There is substantial residential development presently on Perdido Key, but no central sewer system exists to service the area. Currently, only septic tanks and package sewer plants are available for waste treatment purposes on the island. Adjacent to Perdido Key is Old River, which has been classified a Class III water. Soils on Perdido Key are primarily sandy, and as a result, have a high percolation rate. The problem of high percolation rate through the soils of Perdido Key was adequately addressed by Gulfside in the design of percolation ponds associated with the proposed plant. The two percolation ponds are designed to be located at a minimum of four feet elevation above maximum high ground water level. In fact, during DER's review of this application, Gulfside agreed to raise the bottom elevation of these percolation ponds in response to a concern regarding their initial location in close proximity to the water table. The problem of the expected fast percolation rate was addressed in designing the size of these percolation ponds, and also taken into consideration in designing the method of distributing effluent across the bottom surface of the ponds. With regard to the latter consideration, initial design of the project contemplated a single point for discharge of effluent into each percolation pond. However, Gulfside has agreed to redesign these percolation ponds in such a fashion to discharge effluent more evenly throughout the bottom area of the ponds too combat the problem of the excess percolation rate. The proposed percolation ponds are designed with surface areas in excess of 15,000 square feet. The ponds were initially designed utilizing a six-to-one slope, which would have given twice the bottom surface area of the three-to-one slope eventually required by DER in the process of reviewing the application. The three-to-one slope shown in the plans and specifications results in a bottom surface area of 2,974 square feet. However, the engineering report submitted with the application indicates that percolation ponds will have a bottom surface area of 4,480 square feet. From the evidence, it would appear appropriate for the ponds to have a minimum bottom surface area of 4,480 square feet. From the evidence, this problem can easily be rectified by raising the bottom elevation of the percolation ponds by approximately one foot. This requirement should be imposed as a condition to the granting of the requested permit. The proposed plant, although designed to remove 90 percent of B.O.D. and suspended solids, is not designed to remove nutrients from the effluent. However, the evidence establishes that these nutrients. Will be removed by a combination of filtration through soil substrata and biological action in the percolation ponds. Gulfside has also agreed to install a spartina marsh waterward of the percolation ponds to act as a final nutrient scrubber. The system design is reasonably calculated to assure removal of harmful quantities of nutrients, and no competent evidence was adduced to indicate that the system design was not sufficient for this purpose. Thus, although the treatment plant is proposed to be located only 50 feet from Old River, there is no indication that it will, in fact, result in any adverse impacts to that water body. In addition, DER has no rules or guidelines regulating distances from which package sewer plants, such as that proposed in this application, should be located from bodies of water such as Old River. It should be noted here that the application which is the subject of this proceeding is solely for the purpose of construction of the proposed facility. DER has imposed a permit condition requiring an initial four months operation for appropriate testing to determine compliance with the rules and regulations promulgated by DER before issuance of an operation permit. If testing demonstrates noncompliance with DER's rules and regulations, the operating permit for the facility can be denied. Testimony adduced at the hearing established that members of Petitioner, Southest Escambia Improvement Association, Inc., own property in the vicinity of the proposed facility, and that they utilize waters surrounding Perdido Key for sailing, swimming, crabbing and other recreational uses. Both Petitioner and Gulfside have submitted Proposed Findings of Fact. Petitioner's Proposed Findings of Fact numbered 1, 2, 3, 4 and 8 have been substantially adopted in this Recommended Order. Gulfside's Proposed Findings of Fact numbered 1 through 5 have also been substantially adopted in this Recommended Order. To the extent that Proposed Findings of Fact submitted by either Petitioner or Gulfside are not adopted in this Recommended Order, they have been specifically rejected as being either irrelevant to the issues under consideration in this cause, or as not having been supported by the evidence.
Findings Of Fact Petitioner, Department of Health and Rehabilitative Services, is the state agency charged with regulating waste water treatment facilities and any sanitary nuisance which may emanate as a result of such operations pursuant to Chapters 381 and 386, Florida Statutes. Respondent, Larry G. Delucenay d/b/a Madhatter Utilities, Inc., owns and operates the Foxwood Waste Water Treatment Plant which is permitted and certified by the Department of Environmental Regulation. Respondent, in operating the Foxwood system, discharges its treated effluent water by means of two percolation ponds and a drip field located adjacent to the Cypress Cove Subdivision in Pasco County, Florida. Respondent owns and controls percolation ponds which are located adjacent to the Cypress Cove Subdivision and pumps human waste from a sewage treatment plant to percolation ponds in the Cypress Cove Subdivision. Respondent's percolation ponds are located approximately 50 ft. west of several residences and the ponds are accessible to the public. The ponds are elevated from 3 ft. to 5 ft. above the adjacent residential lots in the subdivision. However, there is a sand berm approximately 8 ft. high with a 12 yd. base which serves as a barrier between the percolation ponds and the Cypress Cove residences. On August 5, 1991, environmental health specialist Burke observed liquid flowing through the sand berm. He also observed erosion patterns in the sand on the berm which indicated liquid was flowing through it. Mr. Burke, while in the company of two other employees of Petitioner, observed liquid flowing from the percolation ponds onto Lake Floyd Drive to the south of the ponds. An improperly designed nearby lake exacerbated the flooding into Lake Floyd Drive. Respondent's waste water treatment system is designed according to the manufacturer's specifications. Pasco County allowed a number of developments to be built in the area without an adequate drainage system which adversely impacts Respondent's system to the point whereby untreated drainage outfall is draining into the southeast areas in Cypress Cove. Specifically, Respondent's pond #4 is designed to handle a water level up to 67.33 ft. During the investigation of the case, the water level in that pond was approximately 3 1/2 ft. higher than the designed capacity and was therefore causing overflow into the southeast areas of the development. (Respondent's Exhibits A, B and C.) Noteworthy also was the fact that a developer failed to complete a connection which has impacted Respondent's percolation pond and has forced the water to rise approximately 9 ft. higher than the designed capacity which has resulted in an overflow approximately 3 ft. to 4 ft. into the neighboring subdivision. As a result of the overflow, waste water spills over the percolation ponds and prevents the water from draining through the berms as designed. Petitioner's consulting engineer, Robert William Griffiths, credibly testified that a number of agencies having oversight responsibility such as Pasco County, the Southwest Florida Water Management District and the Department of Environmental Regulation, mandated that the drainage system be completed prior to the entire build-up of Cypress Cove. Despite the mandate, the drainage system was not completed and the County allowed the development to continue. Respondent is properly treating and chlorinating sewage in its plant which complies with Petitioner's requirements for the treatment of sewage in systems designed such as Respondent's. Respondent properly treats sewage flowing through its ponds and its berms are properly maintained. As early as October 1989, Respondent consulted and retained an engineer, Gerald E. Towson, who was commissioned to investigate the specifics of designing a waste water treatment plant based on concerns raised by the Department of Environmental Regulation (DER). As a result of that charge, Towson investigated the area and observed flooding and the stormwater runoff in the Cypress Cove neighborhood and attempted to find a solution to alleviate the problem. Consultant Towson also investigated Respondent's treatment plant to determine if the system was functioning as designed. Based on his observation and inspection of the treatment facility, the facility was operating as it was designed and properly filters and treats the effluent. However, based on Respondent's inability to control the stormwater runoff in the neighborhood created by the excess buildup, Towson concluded that there was no workable solution to the problem. As a result of Towson's inability to find a workable solution to handle the concerns raised by DER, Respondent suggested that Towson locate another wastewater treatment site which he found in a surrounding area. Respondent negotiated a lease arrangement with the landowner and initiated the permit process with DER. After the completion of numerous documents and engineering studies required by the Department of Environmental Regulation, Respondent was able to get the leased site permitted by DER as a slow drip irrigation system during March 1991. However, while construction of the system was scheduled to start during March 1991, as a result of vigorous protests from area neighbors, construction was delayed. Respondent thereafter investigated several sites but was unable to fine a suitable area near Cypress Cove. Towson completed a lengthy and cumbersome process in getting Respondent's construction application processed by DER. Initially the application was filed and following a DER review, a Notice of Intent to Issue was given. Hillsborough County thereafter reviewed the project and following their review, Hillsborough County issued its Notice of Intent to Grant and public notice was given. Based on Respondent's inability to comply with the neighbor's concerns regarding setback problems, DER withdrew its permit during May of 1991. Thereafter, Petitioner became involved in connecting with the Pasco County Public System. That connection was ultimately made and the County gave its approval following a delay based on a review occasioned by an employee who had been on vacation. Upon getting the approval, Petitioner ordered the equipment from a supplier which included installation of a magnetic meter and the necessary hookups into the Pasco County System. A "phased in" connection has been completed and the stormwater runoff problem has been abated. When the problems raised by DER and ultimately Petitioner was first brought to Respondent's attention, Pasco County did not have the capacity to handle the hookups required by Respondent's system. Respondent, has been involved in the installation of waste water treatment plants since 1967. Respondent is qualified as a Class "A" Licensee Waste Water Operator. He has been accepted as an expert in numerous administrative hearings. Respondent purchased the Foxwood System during 1982. Respondent utilized a 13 acre tract near Lake Floyd Drive. The system was licensed and designed with a flow capacity of 300,000 plus gallons per day. During the time when the Administrative Complaint was issued, the flow capacity was 220,000 gallons per day. The storm water system which was to have been completed by developers in the area was not connected to the public system and the County granted numerous other permits to daycare centers and several parking lots were constructed for other newly constructed commercial buildings in the area. As a result of the excess runoff created by the development in the area, Respondent's system was impacted and the water level was raised in the percolation ponds to the point whereby an overflow resulted. Petitioner adduced no evidence which showed that any physical or emotional harm resulted from the runoff. At all times while the concerns were being raised by Petitioner and other oversite agencies, the effluents in Respondent's systems were properly treated. Respondent vigorously attempted to abate the runoff created by the excess buildup in the area despite the fact that the problem was raised by Pasco County and over which Respondent had no control. Throughout the process of attempting to find alternate solutions and ultimately getting permitting approval to start construction of an alternative waste water treatment system, Respondent operated in good faith. When no alternate site became available, Respondent initially made application to connect with Pasco County System and that connection has now been made.

Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant facts are found: Several years prior to1978, petitioner General Development Corporation (GDC) applied to the DER for a dredge and fill permit to remove a plug of land between the Ocean Breeze Waterway and the North Fork of the St. Lucie River. During the course of negotiations for this permit, it was discovered that the North Port St. Lucie Sewage Treatment Plant, owned and operated by General Development Utilities, Inc., a wholly-owned subsidiary of the petitioner, was operating without a permit from the DER and discharging effluent into a ditch which flowed into the Ocean Breeze Waterway. In March of 1978, a temporary operating permit was issued for the sewage treatment plant. In July of 1978, petitioner received from the DER Permit No. 253.123- 1031 to dredge an area approximately 800 feet in length, 90 feet in width and 6 feet in depth in order to connect the Ocean Breeze/Sagamore Waterways to the dead end oxbow of the North Fork of the St. Lucie River. The permit application was given special consideration pursuant to Rule 17-4.28(7), Florida Administrative Code. The purpose for obtaining the permit was to create direct navigable access to the North Fork of the St. Lucie River from thee Ocean Breeze Waterway. The Ocean Breeze Waterway was and is currently connected to the North Fork of the St. Lucie River by a narrow, shallow, meandering creek and lake system. However, there is not a large enough opening to allow the type of navigable access desired by the petitioner for the benefit of 118 lots plotted along the Ocean Breeze and Sagamore Waterways. Among the seven particular or special conditions attached to the dredge and fill permit issued to petitioner was that the earthen plug not be removed until such time as a permanent operational permit was issued for the sewage treatment plant owned and operated by General Development Utilities, Inc. More specifically, petitioner agreed to the following special conditions to the issuance of the dredge and fill permit: "(7) The applicant is aware that the GDC Utilities' sewage plant is providing an unknown quantity of discharge into Ocean Breeze Waterway and that this discharge may be a source of pollution to the receiving body of water unless affirmative steps are taken by the Utilities. The sewage treatment plant is currently operating under a Temporary Operating Permit (TP56-4601). In no case shall the plug at Cove Waterway be removed before an Operation Permit for the STP has been issued by the Department of Environmental Regulation." At time of issuance of the dredge and fill permit, DER personnel considered the quoted special condition number 7 to an integral part of the permit in terms of water quality assurances. General Development Utilities, Inc. has not been able to obtain a permanent operational permit from the DER for its sewage treatment plant which discharges into a ditch that flows into the Ocean Breeze Waterway. Therefore, particular condition number 7 has not been satisfied and petitioner has been unable to proceed with the dredging or removing of the plug under the permit. As a result of the delays in removal of the plug, petitioner has had to repurchase some 41 of the 118 plotted lots. The sewage treatment plant was and is still operating under a temporary permit. General Development Utilities, Inc. has requested a permanent operational permit for the sewage treatment plant and DER has issued a letter of intent to deny such a permit. As a result, General Development Utilities has petitioned DER for site specific alternative criteria pursuant to Rule 17-3.031, Florida Administrative Code. This matter is the subject of a separate proceeding currently being held in abeyance pending a determination of alternative criteria. General Development Utilities, Inc. v. Department of Environmental Regulation, DOAH Case No. 81-177. In September of 1980, petitioner sent a letter to DER requesting that special condition number seven be removed from its dredge and fill Permit No. 253.123-1031. It was intended that this request be considered as a minor modification to the dredge and fill permit. In response, DER's Chief of the Bureau of Permitting, Suzanne P. Walker, informed petitioner by letter dated October 15, 1980, that it was the staff's initial reaction, after a review of the original dredge and fill permit file, that the requirement that the sewage treatment plant obtain a permanent operational permit prior to dredging remain as a condition of the dredge and fill permit. Petitioner was informed that if it wished to pursue the matter further, the project must be reevaluated as a major modification to the dredge and fill permit. A major modification to a permit requires a new permit application and fee and is treated and processed as an initial application for a permit, with the applicant being required to provide reasonable assurances that the water quality standards will not be violated. Upon request for a minor modification, DER simply reviews the file and determines whether the request is obviously environmentally insignificant. After receipt of the letter from Mrs. Walker, petitioner supplied DER with additional water quality data. Based upon this additional data, discussions with DER staff who had been involved with the initial dredge and fill permit and the sewage treatment plant permit, and two days of sampling data collected by DER, DER determined that particular condition number seven was an integral part of the affirmative reasonable water quality assurance provided and should remain a condition of the permit. This determination was communicated to petitioner by letter dated January 7, 1981. The sewage treatment plant discharges treated effluent into a drainage ditch known as C-108. Effluent from the plant first goes into holding or retention ponds. Under its current flow, it takes about forty days for the effluent to be discharged from the plant to C-108 and the Ocean Breeze Waterway. C-108 flows into the Ocean Breeze Waterway, an artificial waterway which is presently connected to the North Fork of the St. Lucie River by a narrow, shallow meandering creek and lake system. The sewage treatment plant currently operates at 300,000 gallons per day but has an authorized capacity to operate at two million gallons per day. It currently contributes approximately two percent of the total daily flow to C-108. The Ocean Breeze Waterway and C-108, independent of the sewage treatment plant, drain approximately 4,000 square acres and produce about 35 percent of the water that will flow into the North Fork. The North Fork is tidal, with four one foot tides per day. The tidal action comprises almost 63 percent of the moving water. At a two million gallons per day discharge, the wastewater plant would be contributing about 12 percent of the water that would be going into the North Fork from the Ocean Breeze Waterway system. In comparison with two adjacent drainage systems, the Ocean Breeze system contributes only about three percent of the fresh water which flows into the North Fork. The dissolved oxygen levels of C-108 are chacteristically below the state standard of five milligrams per liter, primarily due to the seepage of ground water into the canal. Due to man-made alterations and to natural phenomena, the North Fork's dissolved oxygen levels also characteristically fall below state standards. The dissolved oxygen level of the Ocean Breeze Waterway is characteristically above state standards. Higher levels of dissolved oxygen coming from the sewage treatment plant improves the dissolved oxygen levels of the existing system. High levels of nitrogen, phosphate and chlorophyll have been found near the point of discharge. The quality of water in the North Fork is better than in the Ocean Breeze Waterway. It was the opinion of petitioner's experts that no change in dissolved oxygen levels would occur in the Ocean Breeze Waterway or the North Fork if the plug of land between these water bodies were removed. Petitioner's witnesses also opined that the Ocean Breeze/C-108 system was not a source of nutrient enrichment to the North Fork, and that the present creek system provided no water quality benefits in the form of nutrient uptake for the North Fork. It was estimated that, if the plug of land were removed pursuant to the permit, a pollutant placed at the upper end of the Ocean Breeze Waterway would be diluted by 98 percent in 26 hours in lieu of the present 39 hours due to increased flushing. These opinions were based upon analyses by petitioner's witnesses of various samplings and data regarding dissolved oxygen, nutrients and phytoplankton. The respondent's witnesses felt that the poor water quality in the Ocean Breeze Waterway was attributable in large part to the sewage treatment plant discharge and, if the plug of land were removed, the water quality problems would be moved to the North Fork and the St. Lucie River. It was felt that the present creek and lake system -- the narrow circuitous connection presently existing between the canal and the river -- reduces the nutrients which otherwise would flow into the river. These conclusions were based upon DER's own survey, a review of the dredge and fill permit file and a review of the additional data supplied by the petitioner General Development Corporation. No data regarding the water quality of the effluent from the sewage treatment plant was submitted by the petitioner at the time of DER's review of the original application for the dredge and fill permit.
Recommendation Based upon the findings of fact and conclusions of law recited herein, it is RECOMMENDED that the request of General Development Corporation to modify Permit Number 253.123-1031 by removing particular condition number seven be DENIED.

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).
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. BRADWELL, Hearing Officer Division of Administrative Hearings Room 101, Collins Building Tallahassee, Florida 32301 (904) 488-9675 COPIES FURNISHED: Silvia Morell Alderman, Esquire Department of Environmental Regulation Twin Towers Office Building 2600 Blair Stone Reed Tallahassee, Florida 32301 Joseph S.

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".

The Issue The issue in this case is whether the Petitioner has the actual experience required for certification as a Class B domestic wastewater treatment plant operator.
Findings Of Fact By application filed September 16, 1991, James H. Redden applied for certification as a Class B domestic wastewater treatment plant operator. At the time of the application, Mr. Redden was employed as a laboratory technician at a Class B Collier County regional wastewater treatment facility. From August 15, 1978, to July 31, 1989, Mr. Redden was employed at the Colgate-Palmolive Company facility at Jeffersonville, Indiana. The Colgate-Palmolive treatment facility is an Indiana Class D industrial wastewater treatment plant. Mr. Redden is certified by the State of Indiana as a Class D industrial wastewater treatment plant operator. During his employment at the Jeffersonville facility, Mr. Redden held positions as an associate chemist, senior chemist/plant microbiologist, and wastewater treatment plant supervisor. His duties included daily operations and supervision of personnel, scheduling and performance of maintenance activities, budgeting, ordering, materials balance, sludge management, laboratory analysis, quality assurance and quality control programs, and compliance with various state and federal reporting requirements.

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