Findings Of Fact This application is a request for a consumptive water use permit for six wells at the following locations: LATITUDE LONGITUDE 28 degrees 20' 50" 82 degrees 41' 36" (hereinafter referred to as Garden Terrace No.1) 28 degrees 20' 50" 82 degrees 41' 35" (hereinafter referred to as Garden Terrace No.2) 28 degrees 20' 55" 82 degrees 39' 11" (hereinafter referred to as Parkwood Acres No.1) 28 degrees 21' 20" 82 degrees 39' 11" (hereinafter referred to as Parkwood Acres No.2) 28 degrees 21' 49" 82 degrees 38' 56" (hereinafter referred to as New Well No.1) 28 degrees 21' 50" 82 degrees 38' 56" (hereinafter referred to as New Well No.2) Although included in the application, it appears from the record of this proceeding that Garden Terrace No. 1 is to be abandoned by applicant upon completion of its new facilities and therefore is not intended for inclusion in any consumptive water use permit issued pursuant hereto. Further, it appears from the records that the applicant intends to use Garden Terrace No. 2 as an emergency standby supply well only and therefore its average daily withdrawal as reflected on the application is not intended to be included in a consumptive water use permit issued pursuant hereto. Therefore, with those amendments the application seeks, from a total of five wells, a maximum daily withdrawal of 1,501,000 gallons and an average daily withdrawal of 650,000 gallons. The use of this water is for public water supply and appears to be a reasonable, beneficial use consistent with the public interest and not interfering with any legal use of water existing at the time of the application. Further, according to testimony of the staff of the Southwest Florida Water Management District it does not appear that any of the matters set forth in Subsection 16J-2.11(2), (3) or (4), F.S., exist so as to require the denial of this permit. The staff recommendation is that this permit be granted for a maximum daily withdrawal of 1.50 million gallons per day and an average daily withdrawal of .650 million gallons per day. The staff recommendations are subject to the following conditions: That all individual connections to the system be metered. That the permittee shall install totalizing flow meters of the propeller driven type on all withdrawal points covered by this permit with the exception of those wells which are currently gaged together using a single meter. That the permittee shall submit to the District a record of his pumpage for each meter. Said pumpage shall be read on a monthly basis and submitted quarterly to the District by April 15, July 15, October 15, and January 15, for each preceding calendar quarter. That the permittee have water samples from all wells permitted analyzed for chloride on a monthly basis and results submitted to the District by April 15, July 15, October 15 and January 15 for each preceding calendar quarter. That to promote good water management and avoid salt water intrusion that the water be withdrawn at an average of .217 million gallons per day from each of the three following wells: Parkwood Acres Well No. 1, Parkwood Acres Well No. 2, and New Well No. 1. New Well No. 2 shall be operated only to meet peak demand. That Garden Terrace Well No. 2 be used only as an emergency standby well. The applicant entered no objections to the conditions set forth above nor were there any objections from members of the public to the issuance of this consumptive water use permit.
Recommendation It is hereby RECOMMENDED that a consumptive use permit be issued for the five subject wells for the withdrawal of 1.30 mgd maximum daily withdrawal and .65 mgd, average daily withdrawal subject to the conditions set forth in paragraph 4 above. DONE and ORDERED this 15th day of July, 1976, in Tallahassee, Florida. CHRIS H.

The Issue The issues in this case are whether penalties should be imposed and investigative costs and expenses assessed against Respondent for water supply system violations; and, if so, the amount of the penalties and assessments.
Findings Of Fact Respondent, Premier Construction Group, Inc., owns and operates a water treatment plant and associated piping in a commercial building it owns and leases at 2315 Highway 41 North in Inverness. The water treatment plant consists of a 500- gallon tank that holds groundwater pumped from a well. The water in the tank is treated with chlorine and distributed throughout the building for potable water use. The water system serves 25 or more people daily for at least 60 days a year and serves the same people for over six months a year. Respondent owned and operated the water system for 18 and a half years with no violations. Respondent hired a licensed water treatment plant operator to monitor and ensure compliance with applicable DEP rules. In August 2009, Respondent’s licensed operator increased his price substantially. Rick Suggs, as Respondent’s owner and president, disputed the increase and asked the licensed operator to reconsider. Family obligations then required Mr. Suggs to travel to South Carolina for an extended period of time, and Respondent did not attend to the matter further. By the end of August 2009, Respondent’s licensed operator notified DEP that he would no longer be servicing Respondent’s water system as of the end of the month. On August 24, 2009, DEP mailed Respondent a letter relaying this information and putting Respondent on notice that a new licensed operator would have to be hired for September. Notwithstanding Respondent’s communications with its licensed operator and DEP in August, Respondent did not hire a new licensed operator. Mr. Suggs testified that Respondent did not know its licensed operator actually quit until later in September. When this was brought to Mr. Suggs’ attention, he instructed his office manager to hire a replacement. Respondent thought the matter was resolved, but the supposed replacement did not proceed with the work. While Respondent was without a licensed operator, the residual chlorine in the system dropped to zero when tested by DEP on September 17, 24, and 30 and on October 7 and 13, 2009. As a result, the water system did not comply with disinfection requirements during September and October 2009. Respondent did not notify DEP of its failure to comply with disinfection requirements in September and October 2009. No monthly operation reports were submitted to DEP for Respondent’s water system for September or October 2009. No bacteriological samples were collected from Respondent’s water system for the months of September and October 2009. Respondent did not notify DEP of its failure to collect bacteriological samples in September and October 2009. While without a licensed operator, Respondent did not provide public notification of its failure to collect bacteriological samples in September and October 2009. Well into October 2009, Respondent became aware that the supposed replacement licensed operator was not doing work for Respondent. Mr. Suggs hired a replacement licensed operator named Mike Watson, who began servicing Respondent’s water system on November 17, 2009. Public notification of Respondent’s failure to collect bacteriological samples in September and October 2009 was given on November 25, 2009. On December 11, 2009, Respondent submitted a completed DEP Form 62-555.900(22), Certification of Delivery of Public Notice, as to its failure to notify the public of its failure to collect bacteriological samples in September and October 2009. By not having a licensed operator in September and October 2009, Respondent saved $332. By not having bacteriological samples collected and tested in September and October 2009, Respondent saved $60. There was evidence that DEP spent approximately $678 investigating and enforcing the violations. More may have been spent, but no evidence of any additional costs or expenses was presented. There was no evidence of any other water treatment violations by Respondent after October 2009. Although there was a potential that the violations could have posed a health threat, there was no evidence that the public’s health actually was threatened by Respondent’s violations. The water system was tested on November 18, 2009, and did not have any coliform bacteria. The NOV includes corrective actions (essentially coming into and staying in compliance), which Respondent already has taken. The NOV requests that penalties be paid within 30 days by cashier’s check or money order made payable to the “State of Florida Department of Environmental Protection” and including the notations OGC File No. 09-3847-09-PW and “Ecosystem Management and Restoration Trust Fund” to be mailed to DEP’s Southwest District office at 13051 North Telecom Parkway, Temple Terrace, Florida 33637. Respondent believes the penalties sought by DEP in this case are excessive. Mr. Suggs cited Respondent’s clean record for 18 and a half years, his personal and financial difficulties during the two months when the violations occurred, and his responsiveness in correcting violations beginning in November 2009. Mr. Suggs testified that, during mediation, DEP informed him that the penalties could have totaled $115,000 if an unexplained “matrix” had been used to calculate the penalties. Mr. Suggs thought $115,000 was “ludicrous.” Mr. Suggs also requests that the lesser penalties sought in the NOV be further reduced, especially considering that Respondent paid a lawyer $2,800 for representation earlier in the proceeding, until the lawyer withdrew from the case.
The Issue Whether proposed Water Use Permits Nos. 20012236.000 (the Potable Water Permit) and 20012239.000 (the Irrigation Permit) and proposed Environmental Resource Permit No. 43020198.001 (the ERP) should be issued by the Respondent, Southwest Florida Water Management District (the District).
Findings Of Fact The Parties The individual Petitioners, Farnsworth, Roop, and Varnum are all Florida citizens and residents of Sumter County. None of the individual Petitioners offered any evidence relating to direct impacts that the ERP would have on their property. With respect to the Potable Water and Irrigation Permits, anecdotal testimony was presented by Petitioners and Wing and Weir relating to well failures and sinkholes in the area. Two Petitioners, Roop and Varnum, live in close proximity to the property encompassed by the three permits. Petitioner Farnsworth’s property is approximately three and a half miles from the project boundary. Wing and Weir live approximately four and a half to five and 18 miles from the project site, respectively. SCAID is a Florida not-for-profit corporation that has approximately 130 members. Farnsworth, the president of SCAID, identified only Roop and Varnum as members who will be directly affected by the activities to be authorized by the permits. The District is the administrative agency charged with the responsibility to conserve, protect, manage, and control water resources within its boundaries. The Utility and the Authority are limited liability companies, of which the Villages Inc. is the managing partner. The Villages Inc. is a Florida corporation. The Utility, which will serve as a provider of potable water, is regulated by the Public Service Commission, while the Authority which will provide irrigation water, is not. The Villages Inc., Development The Villages Inc. is a phased, mixed use, retirement community, which is located at the intersecting borders of Lake, Marion, and Sumter Counties. Development has been on going since at least 1983, with a current planning horizon of the year 2019. Currently, there are 15,362 constructed dwelling units in the built-out portion of the Villages Inc. that are located in Lake County and the extreme northeast corner of Sumter County. The portion located in Marion County is 60 percent complete, with 750 homes completed and another 600 under construction. Approximately another 22,000 residences are planned for development in Sumter County by the year 2012, with an additional 10,200 by the year 2019. However, the Potable Water and Irrigation Permits are only for a six-year duration, and the ERP has a duration of only six years. None of the permits authorize development activities beyond that time frame. Generally speaking, the three permits at issue include an area owned by the Villages Inc. that lies in northeast Sumter County South of County Road 466 and North of County Road 466A. However, it is not projected that this entire area will be built-out during the terms of three proposed permits. Area Hydrology and Topography In the area of the Villages Inc., there is a layer of approximately five to ten feet of sand at the land surface, which is underlain by ten to 70 feet of a clayey sand. Both of these constitute the surficial aquifer and are extremely leaky, allowing water to percolate easily through to a lower layer. Except in the vicinity of Lake Miona, there is no water in the surficial aquifer except after rainfall events. The clayey sand layer is underlain by the Upper Floridan, a limestone unit. The top of this limestone layer ("the top of the rock") occurs at fluctuating depths of between 30 and 70 feet. At approximately 350 to 400 feet below the land surface, there begins a transition to a denser unit that serves as a confining layer between the Upper Floridan production zone and the Lower Floridan production zone. This confining layer, which was confirmed by drilling at three locations in the Villages Inc. is approximately 150 feet thick in the area of the Villages Inc. Another transition, this time to a less dense formation, begins at approximately 550 to 600 feet, which is considered the top of the Lower Floridan production zone. While testing conducted on the project site indicated almost no leakage between the Upper and Lower Floridan production zones, it is generally known by experts that there is some exchange of water between the two layers. Both the Upper and the Lower Floridan contain water that meets potable water standards and both are considered water production zones. The water quality of the two zones is not significantly different. The project area is prone to karst activity, that is, the formation of sinkholes. Sinkholes are formed as a result of the collapse of the overburden above subsurface cavities which have been formed through a very gradual dissolution of limestone, thus resulting in a "sink" at the land surface. Surface water bodies in the area include Lake Miona, Black Lake, Cherry Lake, and Dry Prairie, as well as several other small wetlands. The Potable Water and Irrigation Permits The potable water permit is for the withdrawal from the Upper Floridan Aquifer of 1.164 million gallons of water per day (MGD), on an annual average, for potable use in residences and both commercial and recreational establishments. It also limits the maximum withdrawal during peak months to 2.909 MGD. The Irrigation Permit is for the withdrawal from the Lower Floridan Aquifer of 2.850 MGD, on an annual average, for use in irrigation. The peak month usage rate permissible under the proposed permit would be 9.090 MGD. Water withdrawal under the Irrigation Permit will be used for the irrigation of residential lawns, common areas, commercial landscaping, and golf courses. Modeling of Drawdowns In assessing the impacts of proposed water withdrawals from an aquifer, District personnel considered effects on the aquifers and on-surface water features in the area. Computer- generated models of the predicted effects of the Potable Water and Irrigation Permits withdrawals provided one of the principal bases for this assessment. The primary geologist assigned to review the permit applications reviewed two of the models submitted by the Utility and the Authority (jointly the WUP Applicants) and ran one personal model of her own in order to predict the effects of the proposed withdrawals on the aquifers, as well as on any wetlands and other surface water bodies. In particular, the models predict both the vertical and horizontal extent to which the withdrawals may lower the level of water within the aquifers and in-surface waters under various conditions. One of the models submitted by the WUP Applicants predicted drawdowns during a 90-day period of no rainfall while the other predicted the impacts of the withdrawals over the life of the permits, considered cumulatively with the effects of withdrawals from the already-existing Villages' development in Sumter, Marion, and Lake Counties. The District’s geologist modeled the impacts of the withdrawals over the life of the permits and included the cumulative effects of all of the current Villages' withdrawals in Sumter County. All of these models included the combined effects of both the proposed Potable Water and the Irrigation Permits. Based upon these models, it is concluded that there will be no significant drawdowns as a result of the withdrawals authorized by the proposed water use permits. Specifically, the only predicted drawdown in the surficial aquifer (0.25 feet of drawdown) is in an area where there are no natural surface water features. Drawdown in the Upper Floridan is predicted at between 0.1 and 0.2 feet, while the drawdown in the Lower Floridan is predicted at a maximum of 1.5 feet. These minor drawdowns are not expected to cause any adverse impacts. Transmissivity is the rate at which water moves horizontally through the aquifer. In areas with high transmissivity, the results of water withdrawals from an aquifer will generally be low in magnitude, but broad in lateral extent. Water withdrawals from areas of low transmissivity will result in cones of depression that are more limited in lateral extent, but steeper vertically. The use of too high a transmissivity rate in a model, would overpredict the horizontal distance of the drawdowns caused by withdrawals, but would underpredict the vertical drawdown in the immediate vicinity of the withdrawal. Conversely, use of too low a transmissivity would over-predict the effects in the immediate vicinity of the withdrawal but underpredict the lateral extent of the drawdown. The WUP Applicants’ models used a transmissivity value for the Lower Floridan Aquifer of 100,000 feet squared per day ("ft.2/d'). The WUP Applicants’ consultant derived the transmissivity values from a regional model prepared by the University of Florida. The regional model uses a transmissivity value for the entire region of 200,000 ft.2/d for the Lower Floridan. While that transmissivity is appropriate for assessing large-scale impacts, on a more localized level, the transmissivity of the aquifer may be lower. Therefore, the WUP Applicants’ consultant met with District representatives and agreed to use a value half that used in the University of Florida model. A similar approach was used for the transmissivity value used in modeling effects in the Upper Floridan. Notably, specific transmissivity values recorded in four wells in the Villages Inc. area were not used because two of these wells were only cased to a depth of just over 250 feet, with an open hole below that to a depth of 590 feet. Thus, the transmissivity measured in these wells reflect conditions in the confining layer at the immediate location of the wells - not the transmissivity of the Lower Floridan production zone. Further, site-specific information on transmissivity, measured during pump tests at individual wells, does not correlate well to the transmissivity of the aquifer, even at short distances from the well. Transmissivities measured at individual wells are used to determine the depth at which the pump should be set in the well, not to determine the transmissivity of the aquifer. Thus, the use of transmissivities derived from the regional model, but adjusted to be conservative, is entirely appropriate. Moreover, using a transmissivity in her modeling of the project impacts of 27,000 ft.2/d for the Lower Floridan Aquifer, the district geologist’s model predicted no adverse impacts. Leakance is the measure of the resistance of movement vertically through confining units of the aquifer. The leakance value used by the District for the confining layer between the Upper and Lower Floridan was taken from the University of Florida model. Tests conducted on the site actually measured even lower leakance values. Thus, the evidence establishes that the leakance value used in the WUP Applicants’ and the District’s modeling for the Floridan confining layer was reasonable and appropriate. Competent, substantial evidence also establishes that the leakance value used for Lake Miona was reasonable. The WUP Applicants submitted to the District substantial data, gathered over several years, reflecting the balance of water flowing into Lake Miona and the lake’s levels in relation to the potentiometric surface. This documentation verified the leakance value used for Lake Miona in the modeling. Finally, the District modeling used appropriate boundary condition parameters. The District modeling used what is known as the "constant head" boundary and assumes the existence of water generated off-site at the boundaries. Such a boundary simulates the discharge of the aquifer at a certain level. The use of constant head boundaries is an accepted practice. The modeling conducted on behalf of the District and the Applicants provides a reasonable assurances that the Potable Water and Irrigation Permits will not cause adverse water quality or quantity changes to surface or groundwater resources, will not cause adverse environmental impacts to natural resources, and will not cause pollution of the aquifer. Furthermore, because the predicted drawdowns are so insignificant, reasonable assurances have been provided that the withdrawals will not adversely impact existing off-site land uses or existing legal withdrawals. The modeling also provides reasonable assurances that the withdrawals will not be harmful to the water resources of the District. Moreover, monitoring requirements included in the proposed Potable Water and Irrigation Permits provide additional reasonable assurance that – should the withdrawal effects exceed those predicted by the modeling – such effects are identified and necessary steps are taken to mitigate for any potential impacts. The District has reserved the right to modify or revoke all or portions of the water use permits under certain circumstances. Specifically, the proposed Potable Water Permit requires a monitoring plan that includes the following pertinent provisions: There shall be no less than three control wetland and ten onsite wetland monitoring sites; A baseline monitoring report, outlining the current wetland conditions; * * * A statement indicating that an analysis of the water level records for area lakes, including Miona Lake, Black Lake, Cherry Lake, Lake Deaton and Lake Griffin, will be included in the annual report; A statement indicating that an analysis of the spring flow records for Gum Spring, Silver Spring, and Fenney Spring, will be included in the annual report; * * * Wildlife analyses for potentially impacted wetlands, lakes, and adjacent property owner uses or wells, including methods to determine success of the mitigation; A mitigation plan for potentially impacted wetlands, lakes, and adjacent property owner uses or wells, including methods and thresholds to determine success of the mitigation; An annual report of an analysis of the monitoring data . . . . Similar provisions are included in the proposed irrigation permit. The WUP Applicants, in conjunction with the District, have developed sites and methodologies for this monitoring. Reasonable Demand The water to be withdrawn under the proposed Potable Water Permit will serve 10,783 people. This total results from the simple multiplication of the number of residences to be built during the next six years (5,675) by the average number of residents per household (1.9). Those numbers are based upon historical absorption rates within the Villages Inc. development since 1983, an absorption rate that doubles approximately every five years. The Utility proposed a per capita use rate of 108 gallons per day for potable use only. District personnel independently verified that per capita rate, based upon current usage in the existing portions of the Villages Inc. and determined that the rate was reasonable. Based upon the population projections and the per capita rate, the District determined that there is a reasonable demand for the withdrawal of the amount of water, for potable purposes, that is reflected in the Potable Water Permit. The Utility has provided reasonable assurance regarding the Utility’s satisfaction of this permitting criterion. As to the irrigation permit, the Villages Inc. plans, within the next six years, to complete the construction of 1,911 acres of property that will require irrigation. The amount of water originally requested by the Authority for irrigation withdrawals was reduced during the course of the application process at the request of the District. The District determined the reasonable amount of irrigation water needed through the application of AGMOD, a computer model that predicts the irrigation needs of various vegetative covers. Since the Authority intends to utilize treated wastewater effluent as another source of irrigation water, the District reduced the amount of water that it would permit to be withdrawn from the Lower Floridan for irrigation. The District, thus, determined that the Authority would need 1.59 MGD annual average for recreational and aesthetic area irrigation and 1.26 MGD annual average for residential lawn irrigation, for a total of 2.85 MGD. The Villages Inc. also plans to accumulate stormwater in lined ponds for irrigation use. However, unlike its treatment of wastewater effluent, the District did not deduct accumulated stormwater from the amount of water deemed necessary for irrigation. This approach was adopted due to the inability to predict short-term rainfall amounts. The uncontroverted evidence of record establishes reasonable assurances that there is a reasonable demand for the amount of water to be withdrawn under the proposed irrigation permit. Conservation and Reuse Measures Both the Utility and the Authority applications included proposed measures for the conservation and reuse of water. The conservation plan submitted in conjunction with the irrigation permit application provides for control valves to regulate both the pressure and timing of irrigation by residential users; contractual restrictions on water use by commercial users; xeriscaping; and an irrigation control system for golf course irrigation that is designed to maximize the efficient use of water. In addition, in the proposed permits, the District requires the Utility and the Authority to expand upon these conservation measures through such measures as educational efforts, inclined block rate structures, and annual reporting to assess the success of conservation measures. The Authority also committed to reduce its dependence on groundwater withdrawals through the reuse of wastewater effluent, both from the on-site wastewater treatment facility and through contract with the City of Wildwood. Reasonable assurances have been provided that conservation measures have been incorporated and that, to the maximum extent practicable, reuse measures have been incorporated. Use of Lowest Available Quality of Water In addition to the reuse of treated wastewater effluent, the Authority intends to minimize its dependence on groundwater withdrawals for irrigation use through the reuse of stormwater accumulated in lined ponds. Thirty-one of the lined stormwater retention ponds to be constructed by the Villages Inc. are designed as a component of the irrigation system on-site. Ponds will be grouped with the individual ponds within each group linked through underground piping. There will be an electronically controlled valve in the stormwater pond at the end of the pipe that will be used to draw out water for irrigation purposes. These lined stormwater ponds serve several purposes. However, the design feature that is pertinent to the reuse of stormwater for irrigation is the inclusion of additional storage capacity below the top of the pond liner. No groundwater will be withdrawn for irrigation purposes unless the level of stormwater in these lined ponds drops below a designed minimum irrigation level. Groundwater pumped into these ponds will then be pumped out for irrigation. Thus, the use of groundwater for irrigation is minimized. The Authority has met its burden of proving that it will use the lowest quality of water available. With respect to the potable permit, the evidence establishes that there are only minor differences between the water quality in the Upper Floridan and Lower Floridan in this area. The Upper Floridan is a reasonable source for potable supply in this area. Thus, reasonable assurances have been provided by the Utility that it will utilize the lowest water quality that it has the ability to use for potable purposes. Waste of Water In regard to concerns that the design of the Villages Inc.'s stormwater/irrigation system will result in wasteful losses of water due to evaporation from the surface of the lined ponds, it must be noted that there are no artesian wells relating to this project and nothing in the record to suggest that the groundwater withdrawals by either the Utility or the Authority will cause excess water to run into the surface water system. Additionally, the evidence establishes that, to the extent groundwater will be withdrawn from the Lower Floridan and pumped into lined stormwater ponds, such augmentation is not for an aesthetic purpose. Instead, the groundwater added to those ponds will be utilized as an integral part of the irrigation system and will be limited in quantity to the amount necessary for immediate irrigation needs. Finally, the water to be withdrawn will be put to beneficial potable and irrigation uses, rather than wasteful purposes. Under current regulation, water lost from lined stormwater ponds through evaporation is not considered as waste. Thus, the Authority and the Utility have provided reasonable assurances that their withdrawals of groundwater will not result in waste. The ERP The stormwater management system proposed by the Villages Inc. will eventually serve 5,016 acres on which residential, commercial, golf course, and other recreational development will ultimately be constructed. However, the proposed permit currently at issue is preliminary in nature and will only authorize the construction of stormwater ponds, earthworks relating to the construction of compensating flood storage, and wetland mitigation. Water Quality Impacts The stormwater management system will include eight shallow treatment ponds that will be adjacent to Lake Miona and Black Lake and 45 lined retention ponds. Thirty-one of these lined ponds will serve as part of the irrigation system for a portion of the Villages Inc.'s development. All of these ponds provide water quality treatment. The unlined ponds will retain the first one inch of stormwater and then overflow into the lakes. The ponds provide water quality treatment of such water before it is discharged into the lakes. The water quality treatment provided by these ponds provides reasonable assurances that the project will not adversely impact the water quality of receiving waters. While they do not discharge directly to surface receiving waters, the lined retention ponds do provide protection against adverse water quality impacts on groundwater. There will be some percolation from these ponds, from the sides at heights above the top of the liner. However, the liners will prevent the discharge of pollutants through the highly permeable surface strata into the groundwater. The Villages Inc. designed the system in this manner in response to concerns voiced by the Department of Environmental Protection during the DRI process regarding potential pollutant loading of the aquifer at the retention pond sites. Furthermore, by distributing the accumulated stormwater - through the irrigation system - over a wider expanse of vegetated land surface, a greater degree of water quality treatment will be achieved than if the stormwater were simply permitted to percolate directly through the pond bottom. There is no reasonable expectation that pollutants will be discharged into the aquifer from the lined ponds. If dry ponds were used, there would be an accumulation of pollutants in the pond bottom. These measures provide reasonable assurances that there will be no adverse impact on the quality of receiving waters. Water Quantity Impacts With regard to the use of lined retention ponds, as part of the Villages Inc.’s stormwater system and the impact of such ponds on water quantity, the evaporative losses from lined ponds as opposed to unlined ponds is a differential of approximately one (1) inch of net recharge. The acreage of the lined ponds - even measured at the very top of the pond banks - is only 445 acres. That differential, in terms of a gross water balance, is not significant, in view of the other benefits provided by the lined ponds. As part of the project, wetlands will be created and expanded and other water bodies will be created. After rainfalls, these unlined ponds will be filled with water and will lose as much water through evaporation as would any other water body. The design proposed by the Villages Inc., however, will distribute the accumulated stormwater across the project site through the irrigation of vegetated areas. The documentation submitted by the Villages Inc. establishes that the ERP will not cause adverse water quantity impacts. The Villages Inc. has carried its burden as to this permitting criterion. Flooding, Surface Water Conveyance, and Storage Impacts Parts of the project are located in areas designated by the Federal Emergency Management Administration (FEMA) as 100-year flood zones. Specifically, these areas are located along Lake Miona, Black Lake, between Black Lake and Cherry Lake, and at some locations south of Black Lake. Under the District’s rules, compensation must be provided for any loss of flood zone in filled areas by the excavation of other areas. The District has determined, based upon the documentation provided with the Villages Inc.’s application, work on the site will encroach on 871.37 acre feet of the FEMA 100-year flood zone. However, 1,051.70 acre feet of compensating flood zone is being created. The Villages Inc. proposes to mitigate for the loss of flood zone primarily in the areas of Dry Prairie and Cherry Lake. At present, Cherry Lake is the location of a peat mining operation authorized by DEP permit. Mining has occurred at that site since the early 1980s. The flood zone mitigation proposed by the Villages Inc. provides reasonable assurance that it will sufficiently compensate for any loss of flood basin storage. The Villages Inc.'s project provides reasonable assurance that it will neither adversely affect surface water storage or conveyance capabilities, surface or groundwater levels or surface water flows nor cause adverse flooding. Each of the 45 retention ponds to be constructed on-site will include sufficient capacity, above the top of the pond liner, to hold a 100-year/24-hour storm event. This includes stormwater drainage from off-site. In addition, these ponds are designed to have an extra one foot of freeboard above that needed for the 100-year/24-hour storm, thus providing approximately an additional 100 acres of flood storage beyond that which will be lost through construction on-site. Furthermore, the Villages Inc. has proposed an emergency flood plan. In the event of a severe flood event, excess water will be pumped from Dry Prairie, Cherry Lake, and Lake Miona and delivered to the retention ponds and to certain golf course fairways located such that habitable living spaces would not be endangered. Environmental Impacts and Mitigation There are 601 acres of wetlands and surface waters of various kinds in the Villages Inc.’s project area. Forty-one acres of wetlands will be impacted by the work that is authorized under the ERP. Each of these impacted wetlands, along with the extent of the impact, is listed in the ERP. The impacts include both fill and excavation and all will be permanent. When assessing wetland impacts and proposed mitigation for those impacts, the District seeks to ensure that the activities proposed will not result in a net loss of wetland functionality. The object is to ensure that the end result will function at least as well as did the wetlands in their pre-impact condition. Functional value is judged, at least in part, by the long term viability of the wetland. While small, isolated wetlands are not completely without value, large wetland ecosystems – which are less susceptible to surrounding development – generally have greater long-term habitat value. The District’s policy is that an applicant need not provide any mitigation for the loss of habitat in wetlands of less than 0.5 acre, except under certain limited circumstances, including where the wetland is utilized by threatened or endangered species. Some wetlands that will be impacted by the Villages Inc.’s project are of high functional value and some are not as good. The Villages Inc. proposes a variety of types of mitigation for the wetlands impacts that will result from its project, all of which are summarized in the ERP. In all, 331.55 acres of mitigation are proposed by the Villages Inc. First, the District proposes to create new wetlands. Approximately 11 acres of this new wetland will consist of a marsh, which is to be created east of Cherry Lake. Second, it proposes to undertake substantial enhancement of Dry Prairie, a 126-acre wetland. Currently – and since at least the early nineties – Dry Prairie received discharge water from the peat mining operation at Cherry Lake. Without intervention, when the mining operations stop, Dry Prairie would naturally become drier than it has been for several years and would lose some of the habitat function that it has been providing. The Villages Inc.’s proposed enhancement is designed to match the current hydroperiods of Dry Prairie, thus ensuring its continued habitat value. Third, the Villages Inc. has proposed to enhance upland buffers around wetlands and surface waters by planting natural vegetation, thus providing a natural barrier. Placement of these buffers in conservation easements does not provide the Villages Inc. with mitigation credit, since a 25-foot buffer is required anyway. However, the District determined that the enhancement of these areas provided functional value to the wetlands and surface waters that would not be served by the easements alone. Fourth, the Villages Inc. will place a conservation easement over certain areas, including a 1500-foot radius preserve required by the Fish and Wildlife Conservation Commission (FWCC) around an identified eagles’ nest. These areas will also be used for the relocation of gopher tortoises and, if any are subsequently located, of gopher frogs. While the Villages Inc. is also performing some enhancement of this area, it will receive no mitigation credit for such enhancement – which was required to meet FWCC requirements. However, since the conservation easement will remain in effect in perpetuity, regardless of whether the eagles continue to use the nest, the easement ensures the continued, viability of the area’s wetlands and provides threatened and endangered species habitat. In order to provide additional assurances that these mitigation efforts will be successful, the District has included a condition in the proposed permit establishing wetland mitigation success criteria for the various types of proposed mitigation. If these success criteria are not achieved, additional mitigation must be provided. With the above described mitigation, the activities authorized under the ERP will not adversely impact the functional value of wetlands and other surface waters to fish or wildlife. The Villages Inc. has met its burden of providing reasonable assurances relating to this permit criterion. Capability of Performing Effectively The Villages Inc. has also provided reasonable assurances that the stormwater management system proposed is capable of functioning as designed. The retention ponds proposed are generally of a standard-type design and will not require complicated maintenance procedures. In its assessment of the functional capability of the system, the District did not concern itself with the amount of stormwater that the system might contribute for irrigation purposes. Rather, it focused its consideration on the stormwater management functions of the system. The question of the effectiveness of the system for irrigation purposes is not relevant to the determination of whether the Villages Inc. has met the criteria for permit issuance. Consequently, the record establishes that the documentation provided by the Villages Inc. contains reasonable assurances that the stormwater system will function effectively and as proposed. Operation Entity The Villages Inc. has created Community Development District No. 5 (CDD No. 5), which will serve as the entity responsible for the construction and maintenance of the stormwater system. CDD No. 5 will finance the construction through special revenue assessment bonds and will finance maintenance through the annual assessments. Similar community development districts were established to be responsible for earlier phases of the Villages Inc. The ERP includes a specific condition that, prior to any wetlands impacts, the Villages Inc. will either have to provide the District with documentation of the creation of a community development district or present the District with a performance bond in the amount of $1,698,696.00. Since the undisputed testimony at hearing was that CDD No. 5 has, in fact, now been created, there are reasonable assurances of financial responsibility. Secondary and Cumulative Impacts The Villages Inc.’s application also provides accurate and reliable information sufficient to establish that there are reasonable assurances that the proposed stormwater system will not cause unacceptable cumulative impacts upon wetlands or other surface waters or adverse secondary impacts to water resources. The system is designed in a manner that will meet water treatment criteria and there will be no secondary water quality impacts. Further, the use of buffers will prevent secondary impacts to wetlands and wetland habitats and there will be no secondary impacts to archeological or historical resources. In this instance, the stormwater system proposed by the Villages Inc. will function in a manner that replaces any water quantity or water quality functions lost by construction of the system. In its assessment of the possible cumulative impacts of the system, the District considered areas beyond the bounds of the current project, including the area to the south that is currently being reviewed under the DRI process as a substantial deviation. The District’s environmental scientist, Leonard Bartos, also reviewed that portion of the substantial deviation north of County Road 466A, in order to determine the types of wetlands present there. Furthermore, the District is one of the review agencies that comments on DRI and substantial deviation applications. When such an application is received by the District’s planning division, it is routed to the regulatory division for review. The District includes its knowledge of the DRIs in its determination that there are no cumulative impacts. Reasonable assurances have been provided as to these permitting criteria. Public Interest Balancing Test Because the proposed stormwater system will be located in, on, and over certain wetlands, the Villages Inc. must provide reasonable assurances that the system will not be contrary to the public interest. This assessment of this permitting criteria requires that the District balance seven factors. While the effects of the proposed activity will be permanent, the Villages Inc. has provided reasonable assurances that it will not have an adverse impact on the public health, safety, or welfare; on fishing or recreational values; on the flow of water; on environmental resources, including fish and wildlife and surface water resources; or on off-site properties. Furthermore, the District has carefully assessed the current functions being provided by the affected wetland areas. With respect to historical or archeological resources, the Villages Inc. has received letters from the Florida Department of State, Division of Historical Resources, stating that there are no significant historical or archeological resources on the project site that is the subject of this permit proceeding. Thus, the evidence establishes reasonable assurances that the Villages Inc.'s stormwater system will not be contrary to the public interest. Additionally, the District and Applicant presented uncontroverted evidence that the proposed project will not adversely impact a work of the District, and that there are no applicable special basin or geographic area criteria.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is: RECOMMENDED that a final order be entered issuing Water Use Permit Nos. 20012236.000 and 20012239.000 and Environmental Resource Permit No. 43020198.001, in accordance with the District’s proposed agency action. DONE AND ENTERED this 24th day of June, 2002, in Tallahassee, Leon County, Florida. DON W. DAVIS Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 24th day of June, 2002.
The Issue In their Prehearing Stipulation, the parties described the nature of the controversy as follows: This matter involves a challenge to a Technical Staff Report and Recommendation made by Respon- dent's staff on a consumptive use permit applica- tion for water submitted to Respondent by Petitioner. Petitioner owns a recreational facility where water is being used. The Staff Report recommends that certain conditions be imposed upon the permit proposed to be issued to Petitioner placing limitations on the amount of water which may be consumed by Petitioner and requiring Petitioner to report on numbers of persons utilizing Respondent's facility. In that same stipulation, the parties described their respective positions as follows: Petitioner's Position: The present use of water at the Wekiva Falls Resort is a reasonable beneficial use which should not be reduced or limited by permit conditions. The standpipes through which the water flows are not wells and therefore should not be subject to any regulation by Respondent. The placement of the standpipes did not increase the flow of water but rather captured the already existing flow from natural springs which existed on the property prior to the placement of the standpipes. Petitioner feels his use does not come within the permitting power of Respondent, and that if it does, its use should be allowed to continue without any reductions in flow. Respondent's Position: After review of Petitioner's consumptive use permit application for the use of water emanating from two standpipes, one twenty-four (24) inches in diameter and the other fourteen inches in diameter, the staff of the District determined that the standpipes were wells subject to the District's regulation under Chapter 40C-2, Florida Administrative Code, and recommended approval of the permit with certain conditions requiring a reduction in flow during certain low or non-use periods. This matter arose from Petitioner's application to the District for a consumptive use permit that would allocate water to the Petitioner from water flowing from a 24-inch metal pipe and a 14-inch metal pipe for use at Petitioner's campground. The District maintains that, not only is the water that is drawn from the metal pipes and used at the campground regulated pursuant to Part II of Chapter 373, Florida Statutes, but also that the remaining water that flows from the two metal pipes and is used by Petitioner to maintain a swimming area is regulated pursuant to Part II of Chapter 373, Florida Statutes. The Petitioner has not applied for an allocation of water for maintaining the swimming area. Even though the Petitioner has not applied for such an allocation, the use of water for maintaining the swimming area has been evaluated because the Petitioner maintained that, even if the water used to maintain the swimming area is regulated pursuant to Part II of Chapter 373, Florida Statutes, the flow of water from the metal pipes should not be restricted in any fashion from the ongoing flow. Thus, the issues presented are whether the application that was applied for should be granted, whether the Petitioner has to apply for an additional allocation in order to continue using water to maintain the swimming area, and what, if an additional allocation is sought, the permit would be. In their Prehearing Stipulation the parties also agreed to the following issues of law. The Division of Administrative Hearings has jurisdiction over the subject matter of and the parties to this proceeding subject to Section 120.57(1), Florida Statutes. To the extent the standpipes located on Petitioner's property are determined to be wells, they are governed by and subject to the provisions of Chapter 373, Florida Statutes, and Chapter 40C-2, Florida Administrative Code. The procedural rules which apply to this proceeding are Chapters 40C-1, 28-5, and 22-I, Florida Administrative Code. The parties also agreed to the following as being the ultimate issues of fact which remained to be litigated. Whether the two standpipes constitute an excavation that was drilled, cored, washed, driven, dug, jetted, or otherwise constructed with the intended use of such excavation to be for the location, acquisition, development, or artificial recharge of water. Whether the continued use by Petitioner of water at pre-permit levels is a use of water in a quantity necessary for economic and efficient utilization for a purpose and in a manner which is both reasonable and consistent with the public interest. Whether the continued use of water by Petitioner at pre-permit levels would increase the danger of saline water encroachment. Whether a reduction in flow of water will result in a reduction in water quality for the uses made of the water by Petitioner. Whether a reduction in flow of water would have adverse impacts on the quality of water in the Wekiva River. Subsequent to the hearing, a transcript of the proceedings at hearing was filed on December 22, 1986, and, pursuant to request of the parties, they were allowed 30 days from that date within which to file their proposed recommended orders. Both parties filed proposed recommended orders containing proposed findings of fact and conclusions of law. The proposed recommended orders have been carefully considered and a specific ruling on each proposed finding of fact submitted by each party is contained in the Appendix which is attached to and incorporated into this Recommended Order.
Findings Of Fact Based on the stipulations of the parties, on the exhibits received in evidence, and on the testimony of the witnesses at the hearing, I make the following findings of fact. Findings based on admissions in prehearing stipulation Petitioner is a private individual who owns and does business as the Wekiva Falls Resort in Lake County, Florida. Respondent, a special taxing district created by Chapter 373, Florida Statutes, is charged with the statutory responsibility of the administration and enforcement of permitting programs pursuant to Part II of Chapter 373, Consumptive Uses of Water, specifically Sections 373.219 and 373.223, Florida Statutes, and Chapter 40C-2, Florida Administrative Code. The District is the agency affected in this proceeding. The District has assigned Petitioner's permit application, which is the subject of this proceeding, the permit number 2-069-0785AUS. On September 4, 1985, Petitioner submitted to Respondent a CUP application number 2-069-0785AUS to withdraw water from two wells, one 14 inches in diameter and the other 24 inches in diameter, located on Petitioner's property in Lake County, Florida. The water which flows from the two standpipes flows through a creek which was improved by Petitioner, said creek having as its terminus the Wekiva River. The standpipes were put in place by Petitioner or his authorized agents or employees in 1972. The area of the Wekiva River into which the creek leading from the two standpipes flows has been designated as an aquatic preserve and an "Outstanding Florida Water." On May 23, 1986, Respondent's staff gave notice of its intent to recommend approval with conditions of Petitioner's CUP application number 2-069- 0785AUS. Petitioner's Petition for Administrative Hearing was timely filed with the District. Findings based on evidence at hearing Petitioner filed his CUP application on September 4, 1985, one week in advance of the September 11, 1985, deadline for existing users of water to file applications which would establish and protect their existing user status. Petitioner's application requests an allocation of 31.7 million gallons per year (mgy) for the following uses: 8 per cent for cooling and air conditioning, 3 per cent for outside use, and 89 per cent for commercial and industrial use. Petitioner has made no application for any allocation of water for water based recreation. The Wekiva Falls Resort property consists of approximately 140 acres stretching 4800 feet in length between Wekiva River Road and the Wekiva River. The property is located along the Wekiva River between State Road 46 and the Orange County, Florida, line. Seminole County, Florida, is on the opposite side of the Wekiva River from the subject property. Petitioner purchased the subject property in 1968. At that time it was a heavily overgrown rural tract. Petitioner observed a stream which came under Wekiva River Road, passing through seven culverts, and running the length of the property to the Wekiva River. This stream carries runoff from Petitioner's property as well as runoff from areas west of the property on the opposite side of Wekiva River Road. At a point approximately midway between the Wekiva River and Wekiva River Road, along the stream, a depressional area was located by Petitioner, through which the stream flowed. Petitioner observed that more water was flowing downstream from the depressional area than upstream. Petitioner's property is located in an area of natural artesian flow where springs or seeps are not uncommon. Because the area in which the subject property is located is one of natural artestian flow, it is likely that a surficial seep of water existed in the depressional area which generated a flow of water. None of the available geological or hydrogeological information or data would indicate the existence of a spring or springs on this site prior to the drilling undertaken by Petitioner. At the time the first well was drilled by Dick Joyce Well Drilling, Inc., no spring was observed by the driller. Further, in conversations with the Executive Director of the District in 1974, no mention was made by the Petitioner of the existence of a spring or springs at the site prior to drilling. On July 17, 1969, Petitioner measured the stream flow and calculated same to be 23.97 cubic feet per second. The methodology utilized by Petitioner in measuring the stream flow in its natural state was an accepted methodology. However, this measurement did not discriminate between the water flowing into the depressional area from the stream carrying runoff from the lands upstream of the depressional area and the water originating from surficial seeps in the depressional area. Thus, this amount cannot be utilized or relied upon as a measurement of the amount of water emanating from seeps in the depressional area before drilling was undertaken by Petitioner. Nevertheless, other evidence indicates that the total volume of water flowing from Petitioner's property into the Wekiva River was probably substantially the same both before and after the installation of the two wells on Petitioner's property. In any event, the installation of Petitioner's wells does not appear to have increased the flow of the Wekiva River downstream of where Wekiva Canoe Creek discharges. In undertaking the development of his property as a resort/campground/recreational vehicle facility, Petitioner dug out the depressional area and used a dragline to open up the creek from the depressional area downstream to the Wekiva River. At a point approximately 200 feet west of the Wekiva River, Petitioner dredged a wide area to construct a marina with access through the creek to the Wekiva River. In an effort to obtain a controlled flow of water, Petitioner contracted Dick Joyce of Dick Joyce Well Drilling Inc. to drill a well fourteen inches in diameter at a site along the bank of the depressional area designated by Petitioner. The well was drilled by Joyce in August of 1972. The well was drilled using a cable rig to a depth of 107 feet, with casing being driven to a depth of 58 feet. The drilling procedure excavated a hole in the ground, penetrated rock, and resulted in the flow of ground water to land surface. The top of the 14-inch well extends 4 to 5 feet above land surface. In a further effort to obtain a controlled flow of water, Petitioner subsequently contracted Central Florida Drillers to drill a second well, twenty- four (24) inches in diameter. This well was drilled in 1973 along the bank of the depressional area, at a spot identified by Petitioner, in the same general vicinity as the previously drilled 14-inch well. The well was also drilled using a cable rig to a depth of 120 feet with casing being driven to a depth of 84.7 feet. The drilling procedure excavated a hole in the ground, penetrated rock, and resulted in the flow of ground water to land surface. The top of the 24-inch well extends 5 feet above land surface. Central Florida Well Drillers Inc. prepared and maintained a driller's log of the 24-inch well, recording the composition of the stratigraphic column through which the drilling equipment passed. The lithology shown in the stratigraphic column is indicative of the geology normally found in a well drilled in this geographical area. The log shows penetration of the normal stratigraphic column for this area and does not show a spring bore that had been filed in by materials at an earlier date. The drilling of the two wells by Petitioner substantially altered the natural conditions on the property as they existed prior to 1972. The top of the Floridan aquifer in the geographical region in which Petitioner's wells are located is encountered at depths ranging from 50 to 100 feet below land surface. The amount of water flowing from the wells has been variously reported and calculated since the wells were installed. Petitioner's promotional materials, which bill the resort as home of the "world's largest flowing well," asserts the maximum free flow capacity to be 72 million gallons per day (mgd). At another point in time, flow from the larger well was said to be 28.8 mgd and the flow from the smaller well 11.5 mgd. Respondent's staff, in preparing its technical staff report, calculated the total flowage from the two wells to be 18 mgd. In his application for a permit to operate a public bathing facility filed with the Florida Department of Health and Rehabilitative Services (HRS), Petitioner indicated the total flowage to be 16 mgd. For purposes of the determination to be made by this Order, the parties stipulated at the hearing to a total flowage figure of 12.47 mgd. Petitioner has operated and continues to operate the facility as a campground and water based recreational site. The central theme of the use of Petitioner's property is the recreational use of water. The water based recreation includes swimming, boating, tubing, and fishing, and is centered around the two flowing wells. The designated swimming area extends from a retaining wall located just west of the westernmost of the two wells to a footbridge which crosses Canoe Creek west of the Marina. The supply of water for recreational use comes primarily from the two wells. The stream which originally existed on the property and which carries runoff from the more western part of Petitioner's property and from off-site enters the designated swimming area at the retaining wall on its westernmost edge. The water which comes from this stream and which is introduced into the western end of the swimming area contains high levels of bacteria and coliforms. Between the hours of 6:00 a.m. and 6:00 p.m., Petitioner operates a sump pump which redirects this high coliform water eastward around a major portion of the swimming area to a point still within the swimming area. For the remaining twelve hours per day, this high bacteria, high coliform water is allowed to flow directly into the swimming area. Petitioner could reduce the level of bacteria and coliforms in the swimming area by simply operating the sump pump for 24 hours a day and/or introducing the water so pumped back into Canoe Creek at a point further downstream east of the designated swimming area. In addition, runoff from a storm drain which was constructed by Lake County, Florida, as a result of an easement granted to them by Petitioner, enters Canoe Creek at a point downstream from the wells but east of the footbridge, within the designated swimming area. When stormwater is conveyed through this storm drain, it also introduces coliforms into the swimming area at the point where the storm drain intersects Canoe Creek. The gate valves on each of the two wells are frozen in a completely open position. The wells are presently flowing at maximum capacity 24 hours a day without regard to whether the facility is being used or not. Petitioner does not presently have the capability to incrementally control the flow of water, short of utilizing a plug to completely shut off the flow of water from one or the other or both of the two wells. Petitioner does, however, have the capability of installing a hydraulic cylinder remote control system in the wells which would allow him to control the flow of water incrementally from the wells via a phone line. The use of Petitioner's facility varies by season, month, day of the week, and time of day, and according to weather conditions on a particular day. Although Petitioner did not have records available showing the number of persons utilizing a particular part of the facility for a particular purpose on a particular day, most of Petitioner's revenue, at least during the summer months, is generated by day use swimmers and picnickers. The swimming facility is most heavily used during daylight hours in the summer months. More customers use the swimming facilities on Saturday and Sunday than during the weekdays. Use is lower during the winter months and during times of inclement weather such as cloudy or rainy days. The evidence fails to show the average number of bathers who use Petitioner's facilities at any particular season or during any particular weather conditions. Petitioner holds a Swimming Pool-Bathing Place Operating Permit for the swimming area issued by the Florida Department of Health and Rehabilitative Services pursuant to Section 10D-5.120, Florida Administrative Code. Responsibility for enforcement of these administrative regulations is with the Lake County, Florida, Public Health Unit. Petitioner's permit allows him to have a maximum swimming pool population of 2000 bathers per day, but there is no evidence that he has ever had that many bathers on a single day since he received the permit. There are two primary water quality parameters which Petitioner is required to maintain within the swimming area, which are delineated in Rule 10D- 5.120, Florida Administrative Code. The first is a flow-through requirement of 500 gallons of water per anticipated bather per 24 hours. On a day when the swimming facility is being utilized by the maximum number of bathers allowable, 2000, the flow requirement for that day would then be one million gallons. For any day when the bathing population fell below 2000, the gallon flow-through requirement would be proportionately reduced. The second water quality parameter Petitioner is required to maintain relates to coliform densities. High coliform count can result in serious illness. The coliform density in the swimming area must not exceed 1000 most probable number of coliform organisms per 100 milliliters. Coliform levels in the swimming area at any given time are dependent upon several variable factors. Among these factors is the number of coliforms being introduced into the swimming area. As has previously been discussed, when the sump pump which reroutes high coliform water around the upper part of the swimming area is not operating, the number of coliforms would increase. Also during periods of rainfall, coliforms are washed into the swimming area in runoff which enters from overland and through the storm drain which enters the lower part of the swimming area. Temperature is a variable factor which affects coliform levels. As temperatures increase, bacteria multiply more rapidly, and thus coliform levels increase. The number of human beings utilizing the water at a given time impacts coliform levels in that, since humans are producers of coliforms, when greater numbers of humans are in the water, higher coliform levels would normally result. These factors coalesce in that high temperatures normally occur during the summer months which contain the days of most intense usage, and thus high coliform levels would be expected during these times if all other factors remain constant. Conversely, during the winter months, when facility usage is lowest and temperatures are lowest, lower coliform levels would be expected. One additional variable factor which affects coliform levels is the amount of water flowing through the swimming area. Water dilutes any contaminants or pollutants that come into the system. Petitioner attempted to show a correlation between rate of flow and coliform levels in excess of 1000 parts per 100 milliliters (ppm). (Petitioner's Exhibit #1) However, because the date collected did not control for and did not take into account the presence or non-presence of the variable factors which affect coliform levels, no conclusions could be reached regarding whether water quality could be maintained in the swimming area in accordance with HRS standards, with periodic adjustments to flow from the wells. No competent substantial evidence was offered to show that periodic adjustments to flow would prevent Petitioner from meeting HRS standards for water quality and therefore prevent Petitioner's continuing the operation of his public bathing facility. The original permit application filed by Petitioner only requested an allocation of 31.7 million gallons per year (mgy), this amount being only the water utilized for the campground. The construction of Petitioner's potable water supply for the campground was approved by the Florida Department of Environmental Regulation and meets all water quality standards applicable to the campground. Although the water used for the campground comes from a pipe connected to the 24-inch well, this request for water is not related to and does not account for the water which flows from the wells into the swimming area and out through Canoe Creek and is used for recreational purposes. The technical staff report (TSR) prepared by Respondent's staff recommends granting an allocation of 31.7 mgy of water to Petitioner for commercial and household uses (to supply the campground) and an allocation of 2.55 billion gallons per year (bgy) of water for recreational uses. The recommended allocation for recreational use breaks down to an average daily use of 7 million gallons per day (mgd), representing a 44 per cent reduction in the amount of water presently flowing from the wells for recreational purposes. The TSR further recommends a maximum daily use for any one day of the year of 18 million gallons of water. This recommendation actually exceeds the present production capacity of the wells. The TSR further recommends that the overall 44 per cent reduction in use of water for recreational purposes be achieved by adjustment of well discharges during non-use periods each day and seasonal non-use periods when bathing and marina use are minimal. This would require installation of operable valves on each of the wells as is also recommended in the TSR. Subject to the limitation imposed by the annual allocation and subject to the maximum daily allocation, Petitioner would make the flow adjustments as conditions warrant and as he sees fit. The Floridan aquifer in the region surrounding Petitioner's property is not expansive; thus there is a maximum amount of water which can be stored within it. Water will tend to discharge at some point within the system when flow is stopped at another point. The drawdown effect on the potentiometric head caused by the 24-inch well after flowing for a period of twenty-four hours can be calculated to extend up to two miles west of that well and further to the east. The excess water flowing through Petitioner's wells, over and above that required for recreational purposes, could be tapped and used by other potential consumers of water within the same vicinity, if Petitioner reduced the flow from his wells. Underlying the Floridan aquifer in the Wekiva River Basin Area is a layer of saline water, the degree of salinity being measured by the chloride concentrations in said water. This underlying saline water is relic sea water and is not salt water being pulled in from the oceans. When water is discharged from the Floridan aquifer and potentiometric pressures are thereby reduced, saline water is allowed to move upward and closer to the Floridan aquifer, resulting in higher chloride concentrations in the water discharged from the Floridan aquifer. The converse is also true. Reductions in discharge tend to increase potentiometric pressures which, in turn, would push the saline water further away from the Floridan aquifer. Chloride concentrations are the basic measurement of water quality. In measuring chloride concentrations in water, 250 milligrams of chloride per liter of water is the significant figure because this measuring point is the highest concentration of chloride that is recommended for public drinking water supplies. Data has been collected regarding chloride concentrations in water taken from the Floridan aquifer beneath the Wekiva River basin and shows significant changes during the period from 1973 to 1986. In a United States Geological Survey (USGS) study of water quality in the Floridan aquifer beneath the Wekiva River basin, conducted in 1973-74, an area or isochlor of water with chloride concentrations exceeding 250 (ppm) was identified. Petitioner's wells were included in this study, and the chloride level in his wells was measured at 230 ppm. The isochlor depicting water with chloride concentrations exceeding 250 ppm extended southward to a point north of Petitioner's property. A follow-up study begun in 1986 shows that the area or isochlor of water with chloride concentrations exceeding 250 ppm has extended itself, moving southward to include and pass the Petitioner's wells, past the Lake County border line which lies to the south of Petitioner's property and into Orange County, Florida. In 1986 Petitioner's wells produced water which measured 296 ppm and 312 ppm respectively. Because the 1986 study was not complete as of the time of hearing, no clear determinations can be made as to the extent to which the Petitioner's wells have contributed to the southward migration of the 250 mg/1 of chloride base line. At a minimum, the withdrawals of water from Petitioner's wells is having a localized impact in the immediate vicinity of those wells. Reduction of the flows from Petitioner's wells would, at a minimum, result in an improvement in the chloride levels in a localized area. That improvement in conjunction with similar improvements at other wells in the area could ultimately result in a more regional improvement of the chloride levels. Because of the factors observed indicating a deterioration of the aquifer systems in the face of increased demand, Respondent's staff has created Special Condition Zones in an effort to identify areas within the Wekiva River basin where hydrologic conditions warrant concern and special attention. Zone One, in which Petitioner's property is located, is the area of greatest concern because of observed changes within the hydrologic regime. Special permit conditions have been created for these zones to insure that no more water than is needed for a specific purpose is allocated to any user in the area. The flows from Petitioner's wells provide a benefit to the Wekiva River by diluting the pollutants which flow into the river. The cascading water from the standpipes aerates the water, which in turn increases the oxygen levels which is of benefit to the invertebrates, fish, and other animals that live in the water. The flows from Petitioner's wells account for approximately six or seven per cent of the flow of the Wekiva River at the gauging station at State Road 46. Nevertheless, no persuasive competent substantial evidence was offered to show that an overall 44 per cent reduction in flow from Petitioner's wells would in any significant way impact the quality of water in the Wekiva River. The District staff recommended that numerous "standard general conditions" and numerous "other conditions" which relate specifically to this project be incorporated in Petitioner's CUP permit. Those conditions are set forth at length in Respondent's Exhibit No. 6 and it would serve no useful purpose to repeat them all here.
Findings Of Fact THE PARTIES CMI is a Florida corporation authorized to do business in Florida. CMI owns a mine site as is depicted in the permit application, which mine site is known as "Pine Level". Alan R. Behrens owns residential property approximately two miles from Pine Level, which abuts Horse Creek. He maintains an individual well for domestic and other purposes, and is a substantially affected person under the statute. Charlotte County is a government entity and a political subdivision of the State of Florida, and is a substantially affected person under the statute. The City of North Port is an incorporated municipality of the State of Florida, and is a substantially affected person under the statute. The Environmental Confederation (ECOSWF), a citizens group, is a substantially affected person under the statute. The District is the agency with the responsibility for reviewing and ruling upon CMI's water use permit application. APPLICATION AND PROCESS CMI proposes to operate a phosphate mine facility at "Pine Level" ("site"). The site is located approximately seven miles west of Arcadia, DeSoto County, Florida. The mine reserves at the site are approximately 17,700 acres. 9,000 to 10,000 acres are projected for mining. In 1978, Consumptive Use Permit No. 200103, was issued and in 1986, the current owners purchased the corporation which held the permit, and changed the name of the corporation to CMI. The Industrial Water Use Permit has not been used since it was issued to a prior owner of the site, and provided for average daily withdrawals of 13.6 mgd from wells. In 1984, this permit was renewed and modified to provide for average daily withdrawals of 12.8 mgd from deep wells. The groundwater withdrawals currently sought by CMI is 6.9 million gallons per day ("mgd") average daily withdrawal, which totals include 5.1 mgd from deep wells for use in the amine flotation process and 1.7 mgd for sealing the matrix slurry pumps. This reduction to 6.9 mgd in permitted withdrawals is a significant reduction. In addition, the proposed permit allows 3.7 mgd to be withdrawn from the surficial aquifer by dewatering mine cuts. In November, 1990, CMI submitted an application for renewal. In November 1991, CMI submitted to the District a revised Water Use Application No. 200103.02 ("application") to renew and modify the existing water use permit. The District requested more information, and CMI provided additional information and supplemental responses to aid in the review and evaluation of the application. The District prepared and submitted a Notice of Intent to Issue Permit and the District staff has prepared a "draft" Permit No. 200103.02 authorizing the withdrawal of the quantities requested in the application with certain conditions. In addition to renewal and modification of the water use permit, which is the subject of this proceeding, CMI will be required to participate in numerous regulatory reviews and permitting procedures (i.e. a development of regional impact evaluation, a federal environmental impact statement, federal approvals under the Clean Water Act [including a national pollutant discharge elimination system ("NPDES") permit], and a conceptual reclamation plan review) before CMI may commence mining, and consequently, begin any withdrawal of water. The mining process will utilize large walking draglines to excavate over burden and stack it beside the active mining area for land reclamation. The ore material called "matrix" will be dug up by the draglines, placed into an earthen pit where it will be slurried with a high pressure water jet. A pump will pick up this slurried matrix material, pump it back to the processing plant where it will first go through various separation devices, including screens and cyclones. The course material termed "pebble" will be separated and parts of that will be directly saleable as a product. The bulk of the phosphate product is contained in intermediate-sized material called concentrate feed. The concentrate feed consists of ore and sand. The ore is separated from the sand in a process called "flotation". The flotation process is a two stage process that ends up separating the tailings sand, which can then go back to the sand-clay flocculation and mixing units, and be pumped out ultimately for land reclamation back in the mine-out areas. The phosphate product which is called "wet rock", is placed in storage bins where it can drain, and be loaded onto rail cars for shipment. The "amine flotation process" is the second stage of flotation where sand and phosphates are separated. This process requires clean water for the amine flotation phase, because any amount of contaminants, including organic reagents, will adversely affect the process. Any mineral particles must be removed so that the amine may attach itself to the phosphate. Any contaminants will destroy or significantly and adversely affect not only the phosphate recovery, but the entire flotation process. Deep well water is requested for use in the amine flotation process because it is clean. All phosphate mines in Florida currently rely on deep well water. 5.2 mgd is the minimum amount of "clean" water needed to assure efficient processing of the amine flotation process of the mine beneficiation plant. Deep well withdrawals are also commonly used for the purpose of sealing or protecting the packing of pumps at various points in the mine system in order to avoid damage to the equipment. These wells are often referred to as "sealing water wells". The Pine Level mine will require 1.7 mgd for this purpose. Water for the sealing water wells must be clean and clear in order to effectively seal pumps for leaks. The Pine Level project will provide 400-500 construction jobs during the construction period. It will provide approximately 200 full-time jobs with an annual payroll of about five million dollars once it is in operation. It will result in about one thousand additional jobs providing services to the development. It will pay in excess of one million dollars a year to DeSoto County in ad valorem taxes. TECHNICAL CRITERIA The water use is a reasonable and beneficial use. 5.2 mgd groundwater withdrawal is "necessary to fill a certain reasonable demand." The technical criteria relating to water level or rates of flow impacts set forth in Rule 40D-2.301(1)(d), Florida Administrative Code, are not applicable in this proceeding because the District has not established any regulatory levels or rates of flow for the area encompassed by the application. In addition, this presumption only addresses surface water withdrawals. Phosphate mining is a beneficial activity and is consistent with the public interest. There is no significant risk of salt water intrusion. The water use withdrawal will not degrade the water quality in the aquifer by causing any contamination plume to spread. There have been no contaminant plumes identified on site. GROUNDWATER IMPACTS There is sufficient ground water at the site of a suitable quality and quantity to support the proposed phosphate mining and beneficiation activities. The local hydrogeology at the site consists of an upper layer known as the surficial aquifer. Rain penetrates the surficial aquifer to flow vertically to the water table. The water that is not consumed by vegetation at this layer will flow either to a nearby stream channel or will leak down through a semi- confining layer. The water continues to seep vertically into the lower underlying limestone aquifers. There are three limestone water-bearing layers: the intermediate, the Suwannee or Upper Floridan, and the Avon Park or Lower Floridan aquifers, respectively. The intermediate and the underlying Suwannee aquifer are separated by another semi-confining layer. Likewise, the Avon Park aquifer and the Suwannee aquifer are separated by another semi-confining layer. At the site, wells in the intermediate aquifer will draw water to seal the bearings on the matrix slurry pumps. There will be one deep well in the Suwannee and one deep well in the Avon Park to draw for the beneficiation plant. The groundwater modeling performed by CMI simulated the four aquifers, that is, the surficial aquifer and each of the three limestone aquifers. An Aquifer Performance Test ("APT") was performed at the site. The data generated from the APT was used to calculate various aquifer parameters, for example, transmissivity, storage coefficient, and leakiness. This information was then used in setting up the groundwater flow model that ultimately was incorporated into the application. During the District staff's review of the application, the deep well withdrawal quantities requested by CMI were compared with approximately 6 other phosphate mines of comparable size, acreage, and type of operation. As a result of this comparison, the staff found CMI's requested use to be less than the other six phosphate mines. The use of recycled water in the amine flotation process in place of deep well water in the past by CMI has proven unsuccessful because a constant temperature and a constant ph level could not be maintained with recycled water, and recycled water contains traces of fatty acids and oils, which also negatively affect the amine flotation process. C.F. Industries, Inc., has been operating a phosphate mine in Hardee County, Florida, since 1978. C.F. Industries, Inc., has since 1983 at the Hardee County mine, successfully substituted recirculation water for deep well water for operation of the amine flotation circuit on a routine basis. C.F. Industries, Inc., presently plans to employ substitution of some recirculation water for deep well water in a new yet-to-be permitted mine. C.F. Industries, Inc., at its existing Hardee County mine requires use of deep well water for start-up purposes to "charge" the system. C.F. Industries, Inc., at its existing mine, uses deep well water to respond to abnormal operational conditions, including excessive rainfall events, when the quality of the normal recirculation water is not suitable for substitution of deep well water. Neither CMI, nor District staff was aware prior to hearing, that the C.F. mine was successfully substituting recycled water for deep well water in the amine flotation process. At the time of making the representations to the District about necessary water quality requirements of the flotation process, CMI had a study, entitled, Amine Water Evaluation, Pine Level Project, July 27, 1984, ("Pilot Plant Study"), which concluded that deep well pumping and discharge could be reduced by use of water drawn from mine cuts. The Pilot Plant study was site specific to CMI's proposed phosphate mine. The Pilot Plant study bench tests were verified in the same pilot plant facility CMI uses to verify the grade of ore on the Pine Level Site. The Pilot Plant study or its results were known to CMI officials or experts involved in the permit application at issue in this case. CMI did not inform District staff of the existence or conclusions of the Pilot Plant study. The Pilot Plant study indicates that CMI could reduce its water usage by substituting water from mine cuts for deep well water. CMI did no studies to determine if the substitution of mine cut water for deep well water, as suggested by the Pilot Plant Study, was feasible to implement. SURFACE WATER IMPACTS The phosphate ore (matrix), is extracted by an excavation machine called a "dragline", which opens mining cuts of approximately 32 to 35 feet in depth, 330 feet wide, and up to 4,000 feet long. Seepage occurs into the mine cuts from the water table, and must be pumped out in order to see and extract the matrix. This dewatering is also necessary to protect the draglines against slope stability problems. Water pumped out of the mining cuts is introduced into the mine water recirculation system which is operated for purposes of collecting and recycling water within the mine complex. The matrix that is extracted from the mining cut is placed in a shallow excavation near the cut, and is converted to a slurry and, thereafter, transported hydraulically to the mine processing (or "beneficiation") plant. The beneficiation plant uses considerable quantities of water, utilizing supplies from within the mine system (i.e. surface water) and water from deep wells. Sand tailings and sand and clay mixture are by-products of the mining process. Recycled water is used to transport waste clay and sand from the plant to the disposal and reclamation areas. Reclamation takes 1-2 years for areas reclaimed with sand tailings and 5-6 years for areas reclaimed with a sand-clay mixture. Groundwater that is used in the processing plant is recycled. Water within the mine is recycled a number of times, and CMI's proposal calls for 90 percent of the total mine demand to be satisfied by this recirculation system and approximately 96 percent of the water used is recyclable water. DEWATERING AND WATER BALANCE CMI's mine pit dewatering activities result in the withdrawal of water from the surficial aquifer. A "water balance" demonstrates that requested quantities relate to reasonable mining, processing, and dewatering needs. The "water balance" for the mining operation evidences a balance between sources and uses/losses. The sources of water in the CMI water balance that input to the mining operation include groundwater from wells (6.9 mgd), mine cut dewatering or water table drainage (3.7 mgd), and collected rainfall (3.1 mgd). Uses and losses associated with the mining operation include water retained in clays (6.7 mgd), water shipped with final product (.7 mgd), evapotranspiration and evaporation (3.0 mgd), water used for agricultural irrigation (5.0 mgd), and water seeping from the Mine Water Surge Area ("MWSA") (1.2 mgd). The water balance matrix moisture component of 2.9 mgd is not a withdrawal of water for water use permitting purposes. The District's modeling of the impacts resulting from mine cut dewatering resulted in a finding of 2.34 MGD as opposed to the 3.7 mgd derived by CMI. For calculation purposes, rainfall is collected at the rate of 3,974 gallons per acre per day. CMI calculates that it will collect 3.1 mgd of rainfall, and use it in its recirculation system. The 3.1 mgd calculation is based on the amount of rain that will fall on 600 acres of mine water surge area, 80 acres of plant site, and two 50 acre mine cuts. CMI plans to mine 450 acres each year at the Pine Level Site over a period of 22 years. Runoff over disturbed areas on the CMI mine site must be captured, and will become part of the recirculation system. Assuming only one year of disturbed area during the permit term, CMI has failed to account for nearly 1.8 mgd in its water balance (450 acres x 3,974 gallons/acre/day). CMI plans to pump any rainfall collected from all disturbed areas to the mine water surge area (MWSA). CMI has not included any acres of disturbed area in its calculations of the amount of rainfall it will collect for the current permit. CMI has not submitted a mine plan. Without a mine plan, the number of disturbed acres cannot be determined. Because CMI's water balance does not include rainfall collected over disturbed areas, the water balance is incorrect. The rainfall collected from the disturbed areas will increase the amount of water that CMI will need to discharge or use for agricultural purposes. Excavation of the Mine Water Surge Area will cause dewatering of the surficial aquifer. No analysis was done of how much dewatering of the surficial aquifer will occur as a result of the excavation of the MWSA, or of the potential impacts to wetlands as a result of the dewatering activities. The District's one foot draw down presumption applies to dewatering as well as to groundwater pumping. The proposed dewatering setback from wetlands was set at 660 feet. The 660 foot setback distance is in lieu of mitigation if CMI wishes to mine within the setback distance, it will be required to implement mitigation procedures. Dewatering draw downs in the surficial aquifer as great as six and one-half to seven feet could occur on the CMI site at 660 feet from a mine cut under dry weather conditions. At 660 feet, the predicted draw down is nearly one and one-half feet using a mine pit depth of 26 feet, based on a three foot water table and a 29 foot average mine cut depth for the area expected to be mined during the term of the permit. Actual mine cut depths during the term of the permit would be as deep as thirty-seven feet which result in a draw down in the aquifer that is greater than one and on-half feet. Combining the dewatering calculations with the surficial aquifer draw downs resulting from CMI's planned well pumping from the intermediate and Floridian aquifers result in greater than predicted draw downs. CMI's water balance did not account for changes in water needs due to variability of the ore body. WATER QUALITY CMI has not demonstrated that the water quantities requested for the operation of the phosphate mine and beneficiation plant, and land reclamation and water handling will utilize the lowest water quality to the greatest extent practicable. Nevertheless, the Pine Level mine is innovative in comparison to other operating mines. It proposes to reduce its groundwater requirement by increasing the amount of recycled water used in the amine flotation process; employ an innovative sand/clay mixing technique for land reclamation, thus eliminating the need for conventional large, above-ground day settling areas or slime ponds; and use surplus water for irrigation of agricultural crops or pasture. CMI plans to mine the Pine Level Site for a period of 22 years. For phosphate mines, neither DNR, nor SWFWMD analyze impacts with respect to surface water during the mining process. For phosphate mines, no state agency looks at off-site surface water impacts from the standpoint of draw downs, with the possible exception of cities and counties. The District has not required CMI to submit an application for the management and storage of surface waters permit, since the District staff believes that phosphate mines are exempt from obtaining any MSSW permit from the District. A gap exists in the regulatory scheme for phosphate mines with respect to the reduction of surface water flows during the mining process if SWFWMD exempts phosphate mines from obtaining an MSSW permit. INTERFERENCE WITH EXISTING LEGAL USERS The City of North Port is an existing legal user of water. The City of North Port has a public water supply facility which draws its water from the Big Slough. The Big Slough normally gets a portion of its flow from high quality water in the surficial aquifer. CMI's proposed Pine Level phosphate mine is located in the watersheds which feed the Big Slough and the Peace River. In the initial years of the mine, virtually all of the collected rainfall will be diverted from the Big Slough watershed. No analysis has been done to see how dewatering might affect the City of North Port. Any significant reduction in flow to the City of North Port's facility during the low flow season will interfere with North Ports existing legal use of water. Diversion of 3.1 mgd of rainfall from the Big Slough will have an adverse impact on the City of North Port's water facility. The City of North Port is currently under a consent agreement with the Florida Department of Environmental Regulation because the water supplied by its facility violates drinking water quality standards for sulfates and total dissolved solids ("TDS") regularly during periods of low flow in the Big Slough. The MWSA, the plant area and the initial mining areas are primarily within the Big Slough drainage area. Seepage of 1.2 mgd from the MWSA will flow into the Big Slough. The only analysis done of the quality of the seepage from the MWSA was a rough analysis which showed that sulfates will likely be around 550 grams per liter. The legal standard for sulfates in drinking water is 250 grams per liter. Seepage from the MWSA will be high in total dissolved solids ("TDS") since a good portion of it was pumped from deep wells which have very high levels of TDS. No analysis was done of the potential of this seepage water to interfere with North Port's facility. Charlotte County is an existing legal user of water whose water supply is drawn from the Peace River downstream from the proposed CMI phosphate mine at Pine Level. Discharge of 5.0 mgd from the Pine Level mine could adversely affect Charlotte County's drinking water facility located on the Peace River. AGRICULTURAL USE CMI proposes to use 5.0 MGD of surplus water for irrigation of pasture grasses for cattle. CMI has not conducted any specific tests to determine the feasibility of using the discharge or the quality of the water that they plan to use for agricultural irrigation. The water for irrigation will be drawn out of the mine water surge area. The determination of whether the 5.0 mgd discharge can be used for agricultural irrigation has been postponed. The staff's position is that the proposed special conditions provide reasonable assurances that the discharge will comply with the requirements of the Basis for Review. WETLANDS Isolated wetlands occur throughout the CMI mine site. The isolated wetlands on the CMI property provide habitat for endangered and threatened species. Sandhill Cranes and Wood Storks, both threatened or endangered species, were sighted on the CMI property by wetlands experts during their site visit prior to the hearing. Small isolated wetlands on CMI property would be adversely affected by less than a one foot draw down. Wetland peat soils oxidize if exposed to the air. Oxidation results in subsidence of the wetland soils, which adversely impacts wetlands. Too much water as well as too little water can adversely impact wetlands. The combined effects of aquifer pumping and dewatering planned at the CMI site will adversely affect wetlands. No analysis was completed of the impacts to wetlands as a result of the combined effects of dewatering and pumping from the aquifer. No information regarding the normal range of wetland hydroperiods for preserved wetlands or other onsite unmined wetlands was introduced. No information was provided regarding the habitat functions provided by the wetlands on the CMI site either for threatened or endangered species or otherwise. ENVIRONMENTAL IMPACT The Applicant did not provide reasonable assurance that the water use will not cause unacceptable adverse impacts to environmental features on or off- site. The Applicant did not provide reasonable assurances that the water use will not have an adverse impact to surface water bodies such as lakes, ponds, impoundments, springs, streams, canals, estuaries or other water courses. The Applicant did not provide reasonable assurances that there will be no adverse environmental impact to wetlands, lakes, streams, estuaries, fish, and wildlife or other natural resources. The Applicant did not provide reasonable assurances that there will be no adverse impacts to the surface water system or vegetation as a result of groundwater withdrawal. The Applicant did not provide reasonable assurances that the water use will not have an adverse impact by altering or impairing the habitat of threatened or endangered species. The Applicant did not provide reasonable assurances that the projected draw downs will not result in any adverse impact to any protected or non-protected plant or animal species. The Applicant did not provide reasonable assurances that the water use will not have an adverse environmental impact to wetlands.

Findings Of Fact Petitioner Ferncrest Utilities, Inc. owns and operates a sewage treatment plant at 3015 Southwest 54th Avenue, Fort Lauderdale, Florida. It presently services the needs of a population of about 2500 primarily located in three trailer parks, certain warehouses, a 153 room hotel, and several other business establishments. The plant was constructed and operated by a lessee of Petitioner's owners, but, in July 1979, Petitioner became the owner and operator of the facility. At that time, it was determined necessary to secure new operators and upgrade the plant equipment and method of process in order to properly service the existing and anticipated future number of customers in the area covered by a Public Service Commission franchise. Although the plant had been operating at a permitted capacity of 0.25 million gallons per day (MGD), Petitioner planned to expand the capacity to 0.60 MGD by modifying the aeration tank, and adding tertiary sand filters and equipment for clarification. Upon assuming control of the plant, Petitioner found that the 0.25 MGD permitted capacity had been exceeded by approximately 120,000 gallons per day for a number of years. Petitioner estimates that a population of 6,000 could be served under its new proposed design capacity. (Testimony of Forman, Exhibit 1) Pursuant to Petitioner's application for a construction permit, dated May 25, 1979, to modify the existing treatment plant, Respondent issued permit No. DC06-21789 on August 6, 1979. The permit specified that it was for construction of additional tank capacity for an existing 0.25 MGD wastewater treatment plant intended to approve effluent quality, and further stated that plant design capacity would remain at that figure. A subsequent letter from Respondent's subdistrict manager to Petitioner on January 15, 1980, stated that an evaluation of the quality of the surface waters receiving the plant discharge and the effect of such increased discharge would have to be made before processing a request for an increase in permitted flow. (Exhibit 7) On February 8, 1980, Respondent issued a temporary operating permit for Petitioner to temporarily operate a 0.25 MGD contact stabilization sewage treatment plant, including additional tank capacity and tertiary filtration. Specific conditions attached to the permit stated that it was issued to give the permittee a reasonable period of time to complete construction of the modification outlined in DER Permit DC06-21789 and for subsequent assessment of the effects of discharge on receiving waters. The conditions further required that the facility continue to achieve 90 percent removal of BOD5 and total suspended solids at all times with specified average daily discharges of such substances. Another condition required that the effluent from the plant be adequately chlorinated at all times so as to yield the minimum chlorine residual of 0.5 parts per million after a minimum contact period of 15 minutes. (Exhibit 8) Thereafter, on July 21, 1980, petitioner filed the instant application for an operation permit for the facility at a design capacity of 0.60 MGD. On October 7, 1980, Petitioner filed a certificate of completion of construction. By letter of December 16, 1980, Respondent's South Florida Subdistrict Manager advised Petitioner that the application for an operating permit had been denied for the reason that monitoring of the Class III receiving waters by the Broward County Environmental Quality Control Board indicated that the dissolved oxygen concentration was frequently below the minimum of 5 milligrams per liter required by Section 17-3.161(1), Florida Administrative Code, and that Petitioner's plant contributed to the substandard conditions in those waters. Petitioner thereafter requested a Section 120.57(1), F.S., hearing. (Exhibits 1-2, 4, 8) Petitioner's plant discharges into the North New River Canal through a six inch effluent pipe. The canal extends from Lake Okeechobee to the intracoastal waterway approximately five miles in distance from the point of discharge of Petitioner's plant. Monitoring of water quality in the canal for the past several years by the Broward County Environmental Quality Control Board shows that the dissolved oxygen concentrations at various sampling stations have ranged from below one part per million to in excess of five parts per million, depending upon the season of the year. However, at no station did the dissolved oxygen concentration reach an average of five parts per million. In addition, the tests also showed that BOD5 is generally low in the canal waters. (Testimony of Mazzella, Exhibits 1, 3, 5) Petitioner's modified plant is now capable of treating 0.60 MGD and meets current basic state requirements of 90 percent (secondary) removal of BOD and total suspended solids. In fact, the plant has tertiary treatment and can consistently operate at a level of 95 percent treatment. The data submitted by the applicant as to effluent water quality characteristics showed removal of 98 percent BOD, 97 percent suspended solids, 50 percent total nitrogen, and 25 percent total phosphorus with an average chlorine residual in the effluent of 0.2 parts per million. The dissolved oxygen level in the effluent has been established at 6.5 milligrams per liter. (Testimony of Hermesmeyer, Dodd, Exhibit 1) Respondent's district personnel took one 24-hour sample of the effluent from Petitioner's plant in March 1981 and determined that a concentrate of 14.6 milligrams per liter of ammonia was being discharged to receiving waters. Respondent therefore determined that the dissolved oxygen levels of the canal would be further degraded because approximately 48 to 50 parts per million of dissolved oxygen would be necessary to offset the effects of oxygen removal resulting from the ammonia discharge. Respondent further found that, although the effluent from the plant had 6.5 milligrams per liter of dissolved oxygen, the amounts of phosphorus and nitrogen being discharged could lead to algal blooms and consequent eventual eutrophication of its waters. Respondent's reviewing personnel therefore considers that there would be negative impacts upon the receiving waters if Petitioner discharged its prior licensed capacity of 250,000 gallons per day, and that a discharge of 600,000 gallons per day would double such impacts. Respondent's personnel therefore believes that although Petitioner's facility meets the basic secondary treatment requirements of Rule 17-6.01, Florida Administrative Code, it does not meet the water quality-based effluent limitation specified in Rule 17-6.10. In order to meet such requirements, it would be necessary to redesign the plant for more efficient removal of nutrients or to redirect the discharge. (Testimony of Mazzella) Other facilities adjacent to or near the North New River Canal discharge directly or indirectly into the canal waters and contribute to an unknown degree to the poor quality of the canal waters. Additionally, agricultural use of land produces stormwater runoff containing fertilizer residue into the canal in an unknown amount. A sewage treatment plant operates at optimum level of treatment when it discharges at about 50 percent of its treatment capacity. (Testimony of Mazzella) In 1983, Broward County will require Petitioner's plant to conform to state advanced waste treatment criteria which will provide for additional removal of nitrogen and phosphorus from effluent. To meet this requirement, Petitioner, plans to investigate the possibilities of utilizing a landlocked lake on its property near the treatment plant as a seepage pond. Although Petitioner's plant is identified in area regional plans to be diverted to the Hollywood wastewater treatment plant in the future, there is presently no target date for tying in to such a regional facility. (Testimony of Hermesmeyer, Exhibit 1)
Recommendation That Respondent issue a permit to Petitioner for the operation of its sewage treatment plant, with appropriate conditions as designed to protect the receiving waters.

The Issue Did Respondents violate the provisions of Rules 62-550.518(3), 62-555.320(4)(8), 62-560.410(2)(c), 62555.350(2), and 62-555.345, Florida Administrative Code, as alleged in the Notice of Violation and Orders for Corrective Action, Case Nos. 96-653PW2442B and 96- 653PW2442C dated June 9, 1997?
Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant findings of fact are made: At all times pertinent to this proceeding, the Department, through the Polk County Health Department, under the authority of an Interagency Agreement with the Department of Environmental Protection, was the agency of the State of Florida charged with the responsibility for inspecting and clearing Public Water Systems in Polk County Florida under Section 403.121, Florida Statutes. SDS Properties Investors Group, Inc. (SDS) is a Florida corporation authorized to do business as Budget Motel. SDS is owned by Shaikh. Sanitary surveys are conducted by the Department every three years and include the inspection of Public Water Systems (PWS) . On January 26, 1996, the Department conducted a routine sanitary survey of Budget Motel (Budget) located at 1418 Highway 17 South, Lake Wales, Florida, which should have included Budget's public water system, PWS 6532442. However, Polk County's inspector, Henry Tagioff, was shown a well, by a Budget employee, that was located on the adjacent property owned by Smokey's Mobile Home Park (Smokey's) and not a part of Budget's water system. Tagioff was not aware that the well he inspected was owned by Smokey's and not on Budget's property. During the inspection, Tagioff noted several violations and advised the Budget employee that Tagioff needed to discuss these violations with Shaikh. On January 29, 1996, Tagioff and Lee Forgey, another Polk County employee, met with Shaikh to discuss the violations noted by Tagioff on January 26, 1996. During this meeting, Shaikh, Tagioff, and Forgey discussed the violations previously found by Tagioff on January 26, 1996, concerning the well on Smokey's property. At no time during this meeting did Shaikh advise Tagioff or Forgey that neither he nor Budget own the well under discussion. The record is not clear, but sometime between January and May 1996, Budget's well had collapsed and was not useable. Subsequent to Budget's well collapsing, Shaikh contracted with George Dunham, after obtaining Smokey's permission, to connect Budget's water system (PWS6532442) to Smokey's well. At the time of connecting Budget's water system to Smokey's well, Dunham advised Shaikh that this was only a temporary solution and gave Shaikh a proposal for a new well since Budget's old well could not be repaired. On May 2, 1996, Tagioff made a reinspection of Budget's water system and found that Budget's well had collapsed and was inoperable, and that Budget had connected to Smokey's well to furnish water to the motel and its guests. Tagioff advised Shaikh that Budget would need a new well since its old well was inoperable and the connection to Smokey's well was only temporary. On May 21, 1996, Mark Fallah, a Polk County employee, conducted a site inspection and prepared a report for use in connection with Budget's application with Southwest Florida Water Management District (SWFWMD) for a new well permit. In connection with Fallah's site inspection and report, the Department advised Shaikh by letter dated May 21, 1996, of certain things concerning the new well that had to be completed prior to placing the well into public use. The letter provides in pertinent part as follows: Upon completion of the drilling and the verification of the grouting procedure by the Water Management District, the following items, as required by Chapters 62-555 and 62550 of the Florida Administrative Code, are to be completed prior to this water system being placed into public use. * * * 2. A continuous chlorination unit that is electrically interlocked with the well pump circuit. * * * A flow measuring device is required on all Non-Community Water Systems. A copy of the well completion report must be furnished to this office by the well driller within thirty (30) days after the well installation. Bacteriological clearance of the well must be performed by submitting twenty (20) consecutive water samples for analysis to an HRS certified laboratory. A maximum of two (2) samples per day taken at least six hours apart may be collected. Additional samples may be required until twenty (20) consecutive satisfactory samples are received. * * * After the well and plant construction is completed, contact our office for an inspection so that written clearance can be issued. It is prohibited for any Public water system to be placed into use without clearance being issued from this department. (Emphasis Furnished). SWFWMD approved Budget's new well application and issued Budget Permit No. 579811.01 for drilling a new well. However, upon completion of the new well, there were certain conditions that had to be met as indicated in the letter from the Department dated May 21, 1996. On May 31, 1996, and July 10, 1996, Fallah inspected Budget's new water system for compliance and, on both occasions, found that Budget had failed to install the chlorination unit, the flow meter, and had not submitted a well completion report or bacteriological samples. On July 15, 1996, the Department issued a Warning Notice to Shaikh advising him that the system could not be used until approved by the Department. For enforcement purposes, the file was transferred to Lewis Taylor, enforcement officer for drinking water systems for Polk County. On November 14, 1996, Taylor conducted an inspection of Budget's water system and reported that: (1) Budget's well had been placed into service without approval from the Department; (2) there was no chlorinator in operation; (3) there was no flow meter; (4) the Department had not received any bacteriological samples since November 1995; (5) there was no certified operator servicing the motel's water system; and (6) Budget had not provided public notice to its customers of its failure to monitor its drinking water. A second Warning Notice was issued by the Department and furnished to Shaikh on November 22, 19-96, which in substance advised Shaikh that Budget was in violation of Rules 62-550 and 62- 555, Florida Administrative Code, for its: (1) failure to obtain the Department's clearance before placing its new well in service; (2) failure to provide quarterly bacteriological samples; (3) failure to maintain proper chlorine residual in the water system; failure to provide a flow meter in the water system; (5) failure to provide public notification to its customers that its water system had failed to comply with Rule 62-550, Florida Administrative Code; and (6) failure to provide the Department with verification of Budget retaining a certified operator to oversee the operation and maintenance of its water system. On March 3, 1997, Tagioff and John GoPaul, US Environmental Agency, inspected Budget's water system and found that: (1) there was no chlorine residual in the system; (2) the chlorination unit located at the motel was not in use; (3) there was no flow meter within the system; (4) no quarterly bacteriological samples had been furnished to the Department; and the well had not been cleared for use by the Department. Based on the testimony of Lewis Taylor which I find credible, the Department has expended the following in the inspection of Budget's water system: (1) 20.25 hours of professional time at a rate of $30.00 per hour for a total of $607.50; (2) three hours of clerical time at a rate of $15.00 per hour for a total of $45.00; and (3) $27.00 in travel costs and postage. The total amount expended in the inspection of this water system by the Department was $679.50.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Department enter a final order finding Respondents guilty of the violations as charged and requiring Respondents to comply with the Orders for Corrective Action as set out in the Notice of Violation and Orders of Corrective Action in Case Nos. 96-653PW2442B and 96-653PW2442C. It is further recommended that Respondents be required to pay the costs and expenses of investigating the violations and prosecuting this matter in the amount of $679.50.

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