The Issue The issue for consideration in this hearing is whether the Respondent, W. B. Persico, should be issued a permit to construct a commercial marina as described in the Department's Intent to Issue, in Class III waters of the state in Charlotte County, Florida.
Findings Of Fact At all times pertinent to the issues herein, the Petitioner, Burnt Store Isles Association, Inc., was an association of property owners whose property is located in the Burnt Store Isles subdivision located in Charlotte County, Florida. The applicant, W. B. Persico, is the owner of a piece of property located adjacent to the subdivision and applicant for a permit to construct a marina on his property. The Department of Environmental Regulation is the state agency responsible for the regulation and permitting of dredge and fill activities in the waters of the state. Mr. Persico's property is located on a dead end basin canal in Charlotte County, Florida. The canal is a Class III water but is not classified as an Outstanding Florida Water. On July 31, 1989, Mr. Persico applied to the Department for a permit to construct a 75 slip, 5660 square foot commercial marina on his property within this artificial, dead end basin. Because of objections by the Department to several aspects of the proposed project, on February 27, 1990, Mr. Persico submitted a modification proposal in which he eliminated the use of pressure treated lumber for pilings, substituting concrete pilings; incorporated boat lifts in each slip; reduced the number of slips from 75 to 65; committed himself to installing a sewage pump-out facility at the site; committed to creating an inter-tidal littoral shelf planted with mangroves; agreed to face the existing vertical bulkhead seawall in the basin with rip-rap; and incorporated a commitment to include, as a part of his rental contract, long term agreements prohibiting vessel maintenance and liveaboards on boats at the site, and insuring the perpetual use of boat lifts and pump out facilities provided. He now proposes to market the marina as a condominium ownership operation. The basin in which the Persico project is proposed is 136 feet across at the entrance, (the narrowest point), and 326 feet across at the widest point. The length of the basin is more than 900 feet. The docking structure to be created will have fingers extending no more than 39 feet into the water from the existing vertical seawall. It will have a 4 foot wide walkway parallel to and 10 feet from the existing seawall from which the arms will extend 25 feet into the basin. The basin which is the proposed location for the marina is at the end of the easternmost canal in the Burnt Store Isles subdivision. It is located just west of and parallel to US Route 41, and at the entrance point, joins a perimeter waterway which meanders approximately 1 mile seaward toward a lock which joins that waterway to Alligator Creek which is an Outstanding Florida Water. The waterway from the basin through the lock into Alligator Creek and thereafter to the Gulf provides the only navigable access for most vessels moored in the Burnt Store canals and which would be moored in the proposed marina between Charlotte Harbor and the Gulf of Mexico. The lock which joints the Burnt Store canals to Alligator Creek consists of two hydraulically operated swinging gates which are operated by a boater entering or exiting the canal system. This lock was constructed as a part of a 1973 agreement between Punta Gorda Isles, Inc., a developer, and the state to prevent the construction and runoff polluted waters of the canal from freely mingling with the Outstanding Florida Water in Alligator Creek. The lock is now maintained in an open position from November 15 to May 15 because boaters complained of the inconvenience of having to operate the lock system. Available evidence indicates that a complete passage through the lock, one way when closed, takes 15 minutes. No more than 24 boats can complete a round trip in a 12 hour boating day. When the lock is open there is no appreciable delay. The residential lots which abut the Burnt Store canals are still mostly vacant. The City of Punta Gorda has assumed the responsibility of conducting a 5 year water quality monitoring program which was previously agreed to by Punt Gorda Isles, Inc. when the lock was built. The 1973 agreement was amended in 1984 to permit the operation of the lock in a closed position for an entire year if water quality monitoring should indicate a degradation of water quality in either Alligator Creek of the Burnt Store Isles canals. This has not been necessary. The Petitioners fear that pollution generated by the addition of 65 additional boats moored at and operating from the proposed marina will cause the Department to implement that clause and order the lock to operate from a closed position year round. This does not mean that the lock would not be opened for boats, but that it would be closed when not being used. Petitioners contend that the increased usage would create an intolerable traffic jam at the lock which would, for the most part, make their use of the waterway to the Gulf intolerable. Mr. Persico is a former road and bridge contractor. Though he has never owned a marina, at one time he rehabilitated one in the Chicago area. He has owned the property in question here for four years and now plans to develop a condominium ownership marina. When he decided to do so, he hired Mr. James M. Stilwell, an environmental consultant, to prepare and submit to the Department the application for the required dredge and fill permit. Initial discussions between Mr. Stilwell and the Department dealt with many environmental issues. Mr. Stilwell pointed out that the water in the canal might already be stale and avenues were explored to mitigate that problem. They did not discuss the type of docks to be installed or the potential for destruction of mangrove stands along the seawall, but even though the original plan called for the docks to be placed against the seawall, it was to be done in such a way as not to disturb the mangroves. The modified plan removing the docks to a point 10 feet off from the wall will obviate any damage to the mangroves. Admittedly, the original submittal prepared by Mr. Stilwell contained factors which were considered unacceptable to the Department. These included construction of the finger piers with pressure treated wood. To eliminate possible pollution from leaching, the pressure treated wood was replaced with a floating dock using concrete pilings. Liveaboards, and the potential contamination from that activity, have been prohibited. The provision and required use of a sewage pump-out facility should prevent any escape of polluting sewage into the waters of the basin. The use of power hoists at each slip should prevent pollution from bottom paint leaching, and boat maintenance at the marina is to be prohibited. Fueling of the vessels will not be permitted at the site thereby obviating the potential of polluting fuel spills. The construction of a 10 foot wide littoral shelf, planted with mangroves, between the dock and the sea wall will provide increased water filtration and improve water quality. It would also help the development of the fish and wildlife population and would reduce the flushing time. Air released into the water from the use of the boat lifts should add oxygen and contribute to improved water quality. At the present time, the ambient water quality in the basin, as it pertains to dissolved oxygen, is probably below standards in the lower depths of the basin, and of the outside channels as well, due to poor light penetration. The channel depth is anywhere from 20 to 25 feet. The oxygen level at the bottom is undoubtedly depleted. Mangroves are currently located along 300 feet of the 1,300 foot seawall. Mr. Stilwell's proposal, and that approved by the Department, does not call for removal of the mangroves, but they would be built around or possibly trimmed. Mr. Stilwell is of the opinion that provision for trimming of the mangroves is inherent in the granting of the permit though such permission was not specifically sought. There is no evidence to contradict this thesis. Water quality issues were raised subsequent to the filing of the original application, and the facility as now planned is designed to minimize impacts on the environment as best as can be done. Water quality would be improved, or at worst not adversely affected, by the prohibitions against liveaboards and fueling, the provision of boat lifts and a pump station, and the prohibition against other structures beyond the dock and slips. Flushing of the water is important considering the fact that the dissolved oxygen content in the water is already low. However, Mr. Stilwell is satisfied, and it would so appear, that water quality would be improved by the implementation of the proposals as included in the conditions to the permit. Mr. Stilwell, admittedly, did no dissolved oxygen tests because they were not considered as a part of the permit application. If the Department requests them, they are done, but they were not requested in this case. It is clear that the original application did not address all the environmental concerns that Petitioners feel are pertinent. Nonetheless, those items already discussed were treated, as were turbidity control during construction. As to others of concern to Petitioners, many are included in the state standards and need not be specifically addressed in the application. The Department considered the application in light of the state standards, and by the use of the conditions appended to the Intent to Issue, provided for the water quality and other environmental standards to be sufficiently addressed and met. In his February 22, 1990 letter to the Department, Mr. Stilwell directly addressed the public interest concerns including the mangroves and the construction of the littoral shelf. The Department was satisfied that the public interest criteria were met, and considered the plans to be environmentally sound. They appear to be so. Petitioners have raised some question as to the effect of the 39 foot long dock fingers interfering with navigation within the basin. Mr. Stilwell does not feel that the facility would create this problem, even at the narrowest point, and it is so found. The width of the canal there is 136 feet. The portion of the slip designed to accommodate vessels is no more than 25 feet long, and presumably, vessels of a length much greater than that would not visit the basin. Even subtracting 39 feet from the 136 feet narrow point, 97 feet of turning space remains, and this is almost four times the length of the normal vessel anticipated in the basin. Mr. Stilwell did not address the subject of the lock as it relates to navigation, but primarily as it relates to the impact on water quality and the environment. Nonetheless, he is of the opinion, and there is no evidence to the contrary, that keeping the lock open on a year round basis would not trigger a change to the ongoing program under the agreement between the state and Punta Gorda Isles and result in the lock being closed year round. Mr. Shultz, the environmental specialist with the Department, reviewed the application here initially for file completeness, and when all required information was in, made a site visit. He evaluated the application and the attachments for permitability. For Class III waters, the project must meet water quality standards outlined in the Department's rules. Only one of the water quality criteria, that of dissolved oxygen, was shown to be not met. Since the water was already below that standard, the test to be applied then is whether the project will create some improvement." In Mr. Shultz' opinion, planting the mangroves, as proposed by the applicant, does this, as does the use of the lifts. The existing mangroves will not be impacted by the project as it is proposed, and the use of rip-rap, as proposed, will provide additional surface area for organisms which will improve the water quality. When first reviewed, the Department had some concern about on-water storage of boats. These concerns were treated by the use of hoists to hold the boats out of the water when not in use, and as a result, pollutants will not be introduced by bottom paint leaching and, presumably, bilge pumping. Standard conditions included in all Department Intents to Issue, require the project to comply with applicable state water quality standards or to give assurances that such general standards for surface waters and Class III waters will be met. In this case, Mr. Shultz is satisfied that the applicant has demonstrated that water quality standards will be maintained, and there was no evidence presented by the Petitioners to contradict this. Once water quality standards are shown to be protected, then the project is balanced against the public interest criteria outlined in the statute. Here, the requirement is for a showing that the project is not contra to the public interest. It does not, because of its nature, require a positive showing that the project is in the public interest. In his opinion this project, as modified, will not adversely affect the health, safety and welfare of the public, (it will have no environmental effect on other property). It will not adversely affect the conservation of fish or wildlife in their habitats, (the planting of mangroves will provide a net improvement to species habitat in the area). The project will not adversely affect navigation, flow of water, or erosion, (the width and length of the dock system appear to pose no threat to navigation in the basin and there would appear to be no obstruction or potential therefor as a result of this project; the project is within a no-wake zone; and the size of vessels is limited by the slip size). The permit will not adversely affect marine productivity, (there is currently very little productivity in the area now since waters below 0 depth of 6 feet are already low in oxygen, and the project would, at least minimally, improve this condition). The project is permanent and would not adversely affect historical or archeological resources in the area, (there are no objects or known resources in the area, but a standard condition in the permit requires immediate notification if known resources or objects are found). The project would not adversely affect the current condition and relative value of functions being performed in the area since the area is currently a real estate development which is far from completely built. Based on his consideration of these criteria, Mr. Shultz concludes that the project is not contrary to the public interest and this appears to be a valid conclusion. There appears to be no evidence of sufficient weight, presented by the Petitioners, either through direct evidence or through cross examination of the applicant and Department witnesses that would tend to diminish the credibility of Mr. Shultz' analysis. If there are subsequent violations, the Department has enforcement action available. There is, consistent with the multiple use zoning category applied to the area across the basin from the marina, the potential for up to an additional 100 docks to be constructed in the basin beyond those treated here. Nonetheless, the Department does not consider 165 boats to be a problem either in the basin or at the lock. This is not necessarily a supportable conclusion, however. Those 100 additional docks do not currently exist and their potential should not be considered in determining whether to approve the permit under consideration here. In opposition to the applicant, Mr. Konover and Mr. Forsyth both indicated that the addition of 65 more boats would seriously overtax the operation of the lock and make it difficult, if not hazardous, to operate boats in that area between the Burnt Store Isles subdivision and Alligator Creek. Both individuals agree, and it is so found, that in general, motor boats pollute to some degree the waters on which that are operated as a result of oil leaks from engine operation, leakage of bilge oil, escape of sewage, and leaching of copper paint and other solvents. In addition, manatee have been seen in the area, and the increase of boating operations could present some hazard to the manatee population. There is, however, no indication that a manatee population is permanently in residence there or is even there frequently. It is also accepted that boat wake has an adverse effect on sea walls, and all of these factors should have been and, in fact were, considered in the analysis of the permitability of the project. The concerns of Mr. Konover and Mr. Forsyth were echoed by Mr. Gunderson who, over 30 years operating boats, has seen what he considers to be a definite lack of concern for the environment by many boaters who pump bilges directly into the water, throw debris overboard, and use detergents to wash their boats at marinas. He is of the opinion that renters of slips are generally less concerned about water quality than those who live on the water, and take a more cavalier approach to water quality standards. These sentiments are also held by Mr. Young who, over the years, has owned marinas in Connecticut and has observed the approach of nonowning slip users to the water at their disposal. His concerns could be met by the strict enforcement of standards at the marina. Mr. Powell, a nurseryman who owns the lot across the basin from the site of the proposed marina, fishes from his lot and has observed the an increase of pollution in the canal. He routinely sees floating dead fish, palm leaves, cocoanuts, bottles, slicks and other debris, and though he owns a multifamily lot, would have a difficult time putting in many slips since his lot, at the entrance to the basin at the narrow point, would be across from the slips proposed by applicant and their proximity would, he feels, hinder his ability to build out into the basin as well.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is, therefore: RECOMMENDED that the Department of Environmental Regulation enter a Final Order issuing Permit No. 081679445, to W. B. Persico as modified and outlined in the Intent to Issue dated March 16, 1990. RECOMMENDED this 9 day of November, 1990, in Tallahassee, Florida. ARNOLD H.

Findings Of Fact The Department of Environmental Regulation (hereinafter "DER") issued a letter of "intent to issue" a permit based upon an application submitted by Respondent John H. Voorhees for a weedgate and associated fences to be placed at the mouth of the Hollerich Subdivision canal in Big Pine Key, Monroe County, Florida. The majority of owners of lots in the Hollerich Subdivision are in favor of the gate. The Hollerich Subdivision canal is approximately 1,200 feet long. it is an east-west dead-end canal with its mouth facing east. Floating seaweeds, grasses and detritus (a/k/a wrack are blown into the canal by the prevailing east and southeast winds. Although some surface wrack may blow back out of the canal with the occasional west wind, the sunken weeds will not. The accumulation of windblown wrack results in a stench caused by hydrogen sulfide gas from rotting weeds. The odor causes nausea, sore throats, and sneezing. Water quality tests of dissolved oxygen (DO) taken both in April 1985 and in November 1986 show the water in the canal to be below state standards. The low DO levels found in the canal are primarily due to the rotting weeds although the nutrients leaching from the surrounding yards also contribute to those low levels. The area outside the canal is better able to diffuse and absorb the wrack problem than the area inside the carnal. Accumulations of wrack outside the canal are more temporary and therefore produce less navigational difficulty and less deterioration of water quality. The navigational problems caused by weeds choking the canal range from difficulty in steering to poor visibility. The decaying wrack also causes growth on boat bottoms, can damage boat cooling systems, and turns the water in the canal red. The amount of wrack entering the canal and accumulating there has been increasing over the last five years. The proposed structure will stop wrack from entering the canal and will function as a weedgate. The design of the gate will not cause any navigational hazards, although the weedgate should have navigational aids to assure safety. Although the weedgate will not improve water quality in the canal so as to meet state standards, it will result in an improvement. DER has no jurisdiction to resolve property disputes. The proposed weedgate is to be placed in front of the canal with no on-land attachments, and Respondent Voorhees has given reasonable assurances that the proposed gate is not on privately owned property. The proposed structure will be placed in Class III Outstanding Florida Waters. DER has balanced the positive public interest effects that will accrue to the owners of property along the canal against the' negative public interest effects that may accrue to owners of property at the mouth of the canal. Respondent Voorhees has given reasonable assurances that the project will be clearly in the public interest. Respondent Voorhees has given reasonable assurances that the proposed project will meet all applicable DER rules and standards.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is, RECOMMENDED that a Final Order be entered (1), granting Respondent Voorhees' permit application and (2), authorizing the issuance of a permit subject to all permit conditions contained in the Department's letter of Intent to Issue the permit and also including the condition that no trespassing occur on the property at the mouth of the canal attendant to either the construction or the maintenance of the weedgate and associated fences.

Findings Of Fact The Petitioner, Bocilla Waterways, Inc., is a corporate entity formed for the purpose of pursuing the subject project and installing the proposed channel. Randall Craig Noden, secretary- treasurer of that corporation, and a director of it, is a realtor who sells and develops property on Don Pedro Island, in the vicinity of the proposed project. He and other officers and directors of the Petitioner corporation have an interest in property on some, but not all, upland areas adjacent to Bocilla Lagoon, Old Bocilla Pass and Kettle Harbor, the water bodies germane to this proceeding. The Respondent, State of Florida, Department of Environmental Regulation, is a state agency charged with regulating dredge and fill projects in state waters and navigable waters pursuant to Chapters 253 and 403, Florida Statutes, and Rule Chapters 17-3 and 17-4, Florida Administrative Code. The Intervenor, Environmental Confederation of Southwest Florida (ECOSWF), is an incorporated, not-for-profit organization whose membership includes numerous environmentally concerned public interest organizations or associations located throughout southwest Florida. Members of the Intervenor use Old Bocilla Pass, Kettle Harbor, Bocilla Lagoon and Lemon Bay, an adjacent contiguous water body, for boating, swimming, fishing (both recreational and commercial), and collecting shellfish. Some of the membership of the Intervenor live in the immediate area of the proposed project. Project Description The Petitioner submitted a dredge and fill permit application to the Respondent, DER, proposing excavation of an access channel through the uplands of Don Pedro Island and adjacent transitional and submerged lands. The channel would be 100 feet wide, 450 feet long and dredged to a depth of -5.0 feet mean low water, with 2:1 side slopes grading to 3:1 at approximately +0.5 feet NGVD. The channel below mean high water would be 70 feet wide' and 670 feet long to a depth of -5.0 feet mean low water, with 2:1 side slopes. A rip-rap strip five feet wide would be placed in the littoral zone on either side of the channel. As originally proposed, the channel excavation would be performed by dragline and clamshell with spoil placed upon uplands for disposal. The excavation would progress from the west side of the project to the east, with plugs remaining at the eastern terminus of the channel until it stabilizes and the rip- rap is placed along the excavated channel. A turbidity curtain is proposed to be used to maintain water quality above state standards regarding turbidity. The applicant originally proposed to transplant seagrasses, displaced in the excavation process, back into the bottom of the excavated channel. Earthen slopes above mean high water would be vegetated in order to achieve stabilization. Some of these proposals were modified after negotiations with DER staff, such that the seagrass transplanting portion of the project would be accomplished in surrounding areas of the water bottom of Bocilla Lagoon and Kettle Harbor, specifically, bare areas and otherwise degrassed, vegetated flats. The applicant also proposes to install navigation aides in Bocilla Lagoon and Kettle Harbor in order to help maintain boat traffic in the channel, and to facilitate ingress and egress through the proposed channel. Don Pedro Island is a barrier island lying off the coast of Charlotte County, Florida. The only access to the island is by boat or helicopter. Bocilla proposes to excavate the proposed channel in order to, in part, provide better navigational access to Bocilla Lagoon which lies within Don Pedro Island. There is presently a navigational channel in the Bocilla Lagoon through what is called "Old Bocilla Pass," located at the north end of Bocilla Lagoon and communicating with Lemon Bay. Bocilla contends that the channel is somewhat tortuous and subject to shoaling, with concomitant grassbed damage by boat propellers, and that thus, a better navigational access in the form of a shorter, deeper, more direct channel from the southern end of Bocilla Lagoon to Kettle Harbor is required. The project would involve the removal of approximately .18 acres of mangroves (red and black mangroves) and .187 acres of seagrasses. Bocilla has proposed to mitigate the damage involved in the mangrove and seagrass removal by replanting mangroves, on three foot centers, along both sides of the proposed channel, and replanting or transplanting seagrasses in bare areas of Kettle Harbor, near the proposed project. Description of Pertinent State Waters Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass are designated as Class II, navigable waters of the state and are designated for shellfish propagation or harvesting. Shellfish, including clams and oysters, occur in Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass. As demonstrated by Intervenor's witnesses Wade, Cole and Wysocki, shellfish are harvestable and harvested in Bocilla Lagoon and Kettle Harbor at the present time. Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass have also been conditionally approved by DNR for shellfish harvesting. DNR approves or prohibits waters for shellfish harvesting, and as a matter of policy generally prohibits shellfish harvesting in manmade "dead-end" canals. A "conditionally approved" water body, such as those involved herein, is an area approved for shellfish harvesting, but one which is more likely to be affected by pollution events. Thus, they are monitored more closely by DNR. Such events as additional residential development in an area, resulting in more septic tank sewage discharge, on-board toilet discharges from boats or the installation of a water and sewer treatment plant, can result in DNR temporarily or permanently closing a conditionally approved area to shellfish harvesting. Natural phenomenon such as the influx of red tide is also a factor which is considered by DNR in electing to classify a shellfish harvesting area as conditionally approved, and in electing to prohibit shellfish harvesting in an area. It was established through testimony of witnesses Feinstein and Setchfield of DER that long-standing DER policy provides that when DNR conditionally approves waters as being shellfish harvestable, that means they are "approved" for all shellfish harvesting purposes, but simply subjected to closer monitoring and with an increased likelihood of closure due to immediate pollution events. Therefore, the prohibition in Rule 17- 4.28(8)(a), Florida Administrative Code, prohibits issuance of dredge and fill permits in areas approved for shellfish harvesting or "conditionally" approved, since there is no difference in the "shellfish harvestable" nature of the waters until a closure occurs, which may simply occur sooner in conditionally approved waters. Bocilla Lagoon and Kettle Harbor are both naturally- formed water bodies, although some dredging has been allowed to occur in them in the past. They are not manmade, "dead-end" canals. Neither water body has the physical or biological characteristics of a "typical dead-end canal". Both are quite high quality habitats for the natural flora and fauna occurring in the marine environment in that area, and thus the general policy of DNR established by witnesses Cantrell, Fry, Feinstein and Sperling which prohibits shellfish harvesting in manmade, dead-end canals, does not apply to Bocilla Lagoon and Kettle Harbor. The water quality in both bodies of water is good and within DER standards generally. At times however, the water quality in Kettle Harbor suffers from a failure to meet DER dissolved oxygen standards contained in Chapter 17-3, Florida Administrative Code. Indeed, the water quality in Bocilla Lagoon is generally somewhat better than the water quality in Kettle Harbor. Environmental Impacts The project as currently proposed would result in the removal of approximately .18 acres of mangroves and .18 acres of seagrasses. Seagrasses and mangroves are important in providing areas of cover, food, and habitat for various estuarine species. Seagrasses serve to stabilize marine soils resulting in a decrease of suspended solids in contiguous waters with resulting decrease in turbidity in those waters. The loss of seagrasses can result in de- stabilization of the bottom sediment, such that suspended solids or turbidity increases in involved waters, which can result in decreased light penetration to the vegetated bottoms. Decreased light penetration, if of a sufficient degree, can result in the further loss of seagrasses and other bottom flora, causing in turn, increased turbidity and further decreased light penetration, with progressively destructive results to seagrass beds and other marine flora and fauna, with a substantial detrimental effect on the marine biological community in general. Mangroves serve as biological filters, trapping sediments, heavy metals, nutrients and other pollutants, uptaking them through their roots and converting them to usable plant food and thus filtering such harmful elements from state waters and rendering them into environmentally harmless substances. The removal of the mangroves at the proposed channel site will result in a loss of their beneficial effects. These beneficial effects will be absent for a greater period of time than it takes to merely plant replacement mangrove plants, since mature trees will be removed and mangrove seedlings will be replanted in their stead. Maturation of mangroves at this location would take in excess of three years, thus replacement of the beneficial filtering effects of the removed mangroves will take in excess of three years, to which time must be added the time which lapses between the original mangrove removal and the replanting of the seedlings, which would start the maturation period. Bocilla proposes to mitigate the removal of the mangroves by that replanting, as well as to transplant seagrasses removed from the channel site to other nearby areas currently bare of seagrass. Seagrass replanting is not a well-established practice. Compared to mangrove replanting, there is less experience, less information and a lower success ratio historically. Of the hundreds of dredge and fill projects occurring and approved throughout Florida, only three have involved replanting of removed seagrasses. Two of the projects involved the Port of Miami in Dade County and the "New Pass site" in Sarasota County. In both of these cases, seagrass replanting cannot be termed successful. The Port of Miami project resulted in a final survival rate of only twelve per cent of ,the grasses replanted. The New Pass project thus far has resulted in a survival rate of only 39 per cent of the seagrasses replanted, after only nine months. The Petitioner proposes that the replanting be accomplished by Mangrove Systems, Inc. That firm is headed by Robin Lewis, who oversaw the seagrass replanting project at the New Pass area in Sarasota. The location and method of replanting seagrasses at New Pass, as to water depth, type of bottom, type of grass and planting method, was generally similar to that proposed for the Bocilla project. That is, it would be accomplished by "plug planting," of "bald" spots at generally the same latitude and similar water depth. The survival rate at the end of six months at the New Pass project was 73 per cent. The survival rate at the end of nine months was 39 per cent. Mangrove Systems, Inc. and Mr. Lewis acknowledges that it is difficult to attribute the decrease in survival rates and grass shoot densities to any one cause, but that predation and a shift in sediments due to the vagaries of water currents, were probably the chief causes for the decrease in seagrass survival. Mangrove Systems, Inc. and the Petitioner propose a guarantee whereby Mangrove Systems, Inc. would replant more seagrasses, if needed, if a low survival rate occurs, which it defines to mean less than a 70 to 80 per cent survival rate after one or two years. There is no guarantee concerning the survival rate after a second planting, however. It was not established when the survival rate will be measured, in determining whether a 70 to 80 per cent survival is being achieved. In this connection, the central Florida coast where the Bocilla project is proposed, is not as conducive to seagrass growth as other more tropical marine areas, such as in the Florida Keys. In the area of the proposed project, seagrasses do not generally produce a great deal of seed and tend not to grow back very readily, once they are destroyed. Seagrasses in the Florida Keys tend to have, in comparison, much greater seed production and for this and other reasons, tend to reproduce themselves more readily once destroyed. They tend to be more amenable to transplanting in the Florida Keys marine environment. Mangrove Systems, Inc. has conducted a seagrass replanting project in the Florida Keys, however. One-third of the seagrasses planted in that project have not survived after two years. In short, the likelihood of seagrass survival has been insufficiently tested in the geographical area and latitude and in similar soils, water depths and temperatures as those involved in the instant case, such that reasonable assurance of adequate seagrass survival with the replanting project proposed will occur. Hydrographics and Maintenance Dredging The evidence is uncontradicted that the opening of the proposed channel would increase circulation in the southern end of Bocilla Lagoon. Increased circulation tends to have good effects in that it reduces stratification in water bodies. Stratification is a condition which occurs when the deeper waters of a given water body do not interchange with surface waters, but rather stratify or become characterized by layers of differing levels of dissolved oxygen, temperature, pH, etc. Typically, lower levels of a stratified body of water are characterized by low levels of dissolved oxygen. The present water quality of Bocilla Lagoon however, is not characterized by statification in any significant degree. It is very similar in water quality, in terms of dissolved oxygen, temperature, pH and other Chapter 17-3 water criteria, to that water quality of the nearby intra-coastal waterway into which the channel into and through Kettle Harbor would open. The intra-coastal waterway is agreed to be a well- circulated body of water, meeting all current State water quality standards. Accordingly, the opening of the channel and the increased circulation it may cause in the southern end of Bocilla Lagoon would have minimal, positive benefits. The change in circulation and in water current patterns and velocities caused by the opening of the direct, shorter channel from lower Bocilla Lagoon and Kettle Harbor may, negatively affect the present seagrass growth in seagrass beds in Kettle Harbor and Bocilla Lagoon in the vicinity of each end of the proposed channel, due in part to increased current velocities that would result from tidal exchange through the shorter, straight channel which would be opened. The expert witnesses in the area of hydrographics disagreed on the effect of the proposed channel on water circulation in the northern end of Bocilla Lagoon and Old Bocilla Pass, which is the north channel opening into northern Bocilla Lagoon. Witness Sperling for the Department opined that a major reduction in flows through Old Bocilla Pass channel would occur. Witness Tackney for the Petitioner acknowledged there would be some reduction in flow, and witness Olsen opined that a reduction in flow would occur, but there could also be an increase in circulation. Both witnesses Tackney and Olsen, in opining that a flow-through, enhanced circulation and flushing system may result from installing the channel, based that opinion to a significant degree, on their belief on the effects of wind on forcing water through the Pass and Bocilla Lagoon. No wind data or records were adduced however, to show the likely effects of wind on creating the Petitioner's desired "flow-through" system. Witness Sperling disagreed as to the significance of this flow-through effect, but there was no disagreement among the hydrographic experts that reduced flows through Old Bocilla Pass, which all acknowledged can occur to one degree or another, can result in increased sedimentation in Old Bocilla Pass, which can result in turn, in the need for increased maintenance dredging in Bocilla Lagoon and Old Bocilla Pass in the future. Maintenance dredging in Old Bocilla Pass may have to be increased if the proposed channel is constructed. The proposed channel itself will likely have to be periodically maintenance dredged as well. Maintenance dredging can cause environmental problems. Dredging activities result in the loss of marine habitat and the destabilization of marine sediments, with resulting increased turbidity and reduced photic effects, with concomitant detrimental effects on seagrasses and other bottom flora and fauna. Increased turbidity resulting from dredging and destabilization of sediments can directly adversely affect shellfish, including clams and oysters. Dredging impacts and siltation can negatively affect seagrass growth and water quality by increasing turbidity resulting in reduced photosynthesis in seagrass, by smothering the seagrass directly and by silting fauna and vegetation in adjacent productive grassbeds. Persons other than the officers and directors of Bocilla Waterways, Inc. own property and have riparian rights on the Old Bocilla Pass channel. These persons have in the past, and have the right in the future, to use Old Bocilla Pass for navigational purposes and could elect to maintenance dredge Old Bocilla Pass as they have in the past. If the proposed channel is constructed, there is obviously a more direct access and shorter water route between the waters of Bocilla Lagoon and Kettle Harbor. Water quality at times in Kettle Harbor has been worse than that in Bocilla Lagoon, especially in terms of low dissolved oxygen. If poorer water quality exists in Kettle Harbor due to low dissolved oxygen, an influx of red tide or some other cause, the construction of the proposed channel would increase the chance, by the more direct connection and increased flow in the southern end of Bocilla Lagoon, to contaminate the water of Bocilla Lagoon. The Public Interest Public opposition was expressed at the hearing, including that of ECOSWF, the Intervenor, some of whose members include people who live in the area of the proposed channel and use the involved waters. Local fishermen who harvest shellfish and finfish in Bocilla-Lagoon and Kettle Harbor, and use Old Bocilla Pass for navigation between Lemon Bay and Bocilla Lagoon, oppose the project, some of whom are members of the organized Fishermen of Florida, an association of approximately 25,000 members. Residents of Bocilla Lagoon and the immediate area, who habitually navigate Old Bocilla Pass, including local fishermen, have had little trouble navigating Old Bocilla Pass because they are familiar with the channel. Although the Petitioner alleges that the new channel is needed in part for the safety of people living on Bocilla Lagoon to assure quick access to the mainland in case of medical emergencies, the members of the public living on Bocilla Lagoon, (with one exception) and on surrounding areas of the island, do not wish such increased access for medical purposes. The island is presently reached from the mainland by either watercraft or helicopter. Formerly, there was a bridge connecting the island with the mainland which has since been destroyed, and not rebuilt. The residents living on Bocilla Lagoon, either full- time or part-time, buy their homes and choose to live there with knowledge of the present mode of access through Old Bocilla Pass, which is also the means they would achieve access to the mainland in case of medical emergencies or, alternatively, by helicopter transport or by transport over island roads to the ferry landing, with access to the mainland by ferry. The residents, in general, desire to maintain the isolation of life on the island as it presently exists and do not desire enhanced access between the island and the mainland, since part of the charm of having homes and living on the island is its isolation from the more populous mainland. Other than the testimony of Petitioner's witnesses, there was no testimony presented expressing any public need for the proposed channel, as for instance from public officials having knowledge of any medical or public health need for enhanced access to Bocilla Lagoon and the island. The proposed project is contrary to the public interest due to its adverse effects on seagrasses, shellfish, and water quality as delineated above. The adverse effects on seagrasses would result from the dredging itself and the destruction of a portion of the extant seagrass beds, and the resultant likelihood of poor survival rates in the attempted transplanting of seagrass as a replacement for that destroyed by the channel dredging. The proposed project is not in the public interest of those people with riparian rights on Old Bocilla Lagoon and northern Bocilla Lagoon, as there is substantial likelihood the proposed project will reduce flows through Old Bocilla Pass' channel with the resultant increased settling out of sediment and thus increased shoaling of that channel, which would concomitantly increase the need for maintenance dredging in Old Bocilla Lagoon and channel. Additional maintenance dredging and the possible negative effects of such additional dredging on marine, flora and fauna in Bocilla Lagoon and Old Bocilla Pass constitute an additional burden on these riparian owners, the bearing of which is not in their interest. The proposed project is also contrary to the public interest in that the proposed channel is deeper, wider and more direct as an entry into Bocilla Lagoon from Kettle Harbor and Lemon Bay, and would thus allow larger, deeper draft boats to enter Bocilla Lagoon with concomitant increased pollution from oils, greases and possible discharge of onboard sewage, which could have adverse environmental impacts on water quality in Bocilla Lagoon, as well as Kettle Harbor. The use of deeper draft, larger boats with larger propellers and more powerful engines could also result in damage to adjacent grassbeds in the vicinity of either ends of the proposed channel, either through direct propeller contact or through prop wash, when such boats are navigated in areas minimally deep enough to accommodate their draft. Since the installation of the proposed channel would result in a deeper, more readily used access to Bocilla Lagoon by larger boats with the remaining original channel usable also, at least for a time, there is a-substantial likelihood of increased residential development on riparian property around Bocilla Lagoon. This could have the result of reducing water quality in the lagoon, or potentially so, through septic tank leachate, stormwater runoff and other adverse environmental effects, such that the water in the lagoon traditionally approved for shellfish harvesting may be prohibited in the future.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is, therefore RECOMMENDED: That a Final Order be entered by the Department of Environmental Regulation denying both the variance application and the permit application sought by Bocilla Waterways, Inc.

The Issue The issue in this case is whether the Southwest Florida Water Management District (the District) should grant the application of the Misty Creek Country Club, Inc. (the Club), to modify MSSW Permit No. 400037.
Findings Of Fact Background Petitioners are owners of property adjacent to Lake No. 7 of the Misty Creek Country Club in a development called The Preserves at Misty Creek-- specifically, lot 113 (Robert and Lee Werner), lot 114 (Charles and Rosemary Biondolillo), lots 115 and 115A (Ignatius and Judith Bertola), lots 117 and 117A (Don and Halina Bogdanske), lots 118 and 118A (Louis and Betty Mitchell), lots 119 and 119A (George and Dorothy Holly), lots 120 and 120A (John and Maureen Higgins), and lot 121 (William and June Spence). Respondent, the Misty Creek Country Club (the Club), operates a golf course and country club located at The Preserves at Misty Creek under a 99-year lease with Gator Creek Lands, the developer of The Preserves at Misty Creek. Existing System Design and Application for Permit Modification In 1985, Respondent Southwest Florida Water Management District, issued a surface water management permit for development of a 730-acre residential development and golf course. The District subsequently issued to the Club operation phase authorization for the surface water management system associated with the golf course portion of the development in March of 1992. Under the original permit, Lake No. 7 was part of the overall stormwater management system for the golf course. The lake is approximately seven and half to eight acres in size and is part of a total drainage basin of approximately twenty-eight acres. As originally designed, Lake No. 7 is a detention with filtration system. An underdrain in the side of the bank provides water quality treatment, filtering out oils and greases, fertilizers and other contaminants. A control elevation of 31.02 was established for Lake No. 7 through construction of a weir. Between elevation 31.00 and 31.02, water discharges through the underdrain system providing water quality treatment. Above elevation 31.02, water flows over the control structure into Lake No. 6, and ultimately discharges to Cow Pen Slough, which is Class III waters of the state. The Club presently has a water use permit from the District which allows withdrawal of groundwater for irrigation of the golf course. Groundwater is stored in Lake No. 7 prior to use for irrigation when needed to augment water in the lake. Special Condition Number 2 of the water use permit required the Club to investigate the feasibility of using reclaimed or reuse water in lieu of groundwater for irrigation purposes at the golf course. As a result of the investigation required by Special Condition Number 2 of the water use permit, the Club filed an application with the District to modify its surface water management permit to allow for the introduction of reuse water into Lake No. 7. Under that application, there would have been no significant modifications to the stormwater management system. Reuse water would have replaced groundwater as a source for augmenting water in the lake when needed for irrigation. An eight-inch service line would convey the reuse water to Lake 7, and a float valve would control the introduction of reuse water into Lake No. 7. When water levels in the lake fell below elevation 30.5', the float valve would open the effluent line to allow introduction of reuse water into the lake; when the water elevation in the lake reached 31.0', the float valve would shut off the flow of water. There would be gate valves on either side of the structure that could be manually closed, if necessary, to stop the flow of reuse water into the lake if the float valve malfunctioned. Club personnel would have access to the gate valves and could manually stop the flow of reuse water into the lake if necessary. On August 9, 1995, just days prior to the final hearing in this matter, the Club proposed to modify its application to make certain structural changes in the design of the surface water management system. Specifically, the Club proposed to plug the window in the weir, raise the elevation of the weir or control structure to elevation 33.6, raise the elevation of the berm along the north end of Lake No. 7 adjacent to the weir to elevation 33.6, and plug the underdrain. The purpose of the proposed modifications to the design of the system was to assure that no discharge from Lake No. 7 would occur up to and including the 100-year storm event. A 100-year storm event is equal to 10 inches of rainfall in a 24-hour period. Source and Quality of Reuse Water The Club also entered into an agreement with Sarasota County to accept reuse water from the county's new Bee Ridge wastewater treatment facility. That agreement specifies the terms under which the Club will accept reuse water from the County. The County's Bee Ridge facility is presently under construction and is not yet operating. As permitted by the Department of Environmental Protection, the Bee Ridge wastewater treatment facility will use a Bardenpho waste treatment system which is a licensed process to provide advanced waste treatment. The construction permit establishes effluent limits for the facility that are comparable to a level of treatment known as advanced secondary treatment, but the County Commission for Sarasota County has instructed the County staff to operate the Bee Ridge facility as an advanced waste treatment plant. Advanced waste treatment is defined by the quality of the effluent produced. For advanced waste treatment, the effluent may not exceed 5 milligrams/Liter of biochemical oxygen demand (BOD) or total suspended solids (TSS), 3 milligrams/Liter of total nitrogen, or 1 milligram/Liter of total phosphorus. It also requires high level disinfection. Advanced secondary treatment requires the same level of treatment for TSS but the limit for nitrates is 10 milligrams/Liter. High level disinfection is also required for advanced secondary treatment. In Florida, reuse systems require a minimum of advanced secondary treatment. High level disinfection is the level of treatment that generally is accepted as being a reasonable level of treatment. The Bee Ridge permit issued to Sarasota County identifies the Club as one of the recipients of reuse water for irrigation. Condition Number 21 of that permit provides that the use of golf course ponds to store reuse water is not authorized under the County's permit until issuance of a separate permit or modification of the County's permit. Although the District did not require Misty Creek to submit any information about the modification of the County's permit, there was no basis for assuming that the County permit could not be modified. To the contrary, the permit provides that authorization may be obtained by permit modification. Under the late modification to the Club's application, the reuse water transmission line and float valve system, with backup manual gate valve system, is unchanged. So are the water elevations at which the float valve system will automatically introduce reuse water into Lake 7 and shut off. Sarasota County already has constructed the water transmission system that would deliver reuse water to the Club. At the request of the District, the Club provided copies of the drawings of the float valve structure as permitted by the Department of Environmental Protection. The District did not require certified drawings of that structure. But the District will require the Club to provide as-built drawings following completion of construction prior to the introduction of reuse water into Lake No. 7. Property Ownership Each of the Petitioners owns a residential lot adjacent to Lake No. 7. At the time of the Petitioners' purchase of the individual residential lots, the Club leased certain property immediately west of Lake No. 7 from the developer of The Preserve at Misty Creek. The leased premises included a piece of land extending into the lake known as the 19th green. As a result of negotiations between the Club and the developer, it was determined that the 19th green would be removed and the land between the approximate top of bank of Lake No. 7 and the private residential lots would be released from the Club's lease. The developer subsequently conveyed the property that had been released from the Club's lease to the individual lot owners (the "A" parcels listed in Finding 1). At the time of the conveyance of the additional parcels, the attorney for the developer prepared deeds for each individual parcel with a metes and bounds description off the rear of the residential lots to which they were being added. While the Club's application for modification of its surface water management permit was being processed by the District, counsel for Petitioners provided the District with copies of the individual deeds and questioned whether the Club had ownership or control of the land which was the subject of the application sufficient to meet the District's permitting requirements. In response to a request for information regarding the ownership of the property that was the subject of the application, the Club submitted to the District a topographical survey prepared by Mr. Steven Burkholder, a registered professional land surveyor with AM Engineering. The topographical survey depicted: the elevation of the water in the Lake No. 7 on the day that the survey was conducted, labeled "approximate water's edge"; the elevation of the "top of bank"; and the easternmost line of private ownership by Petitioners. Mr. Burkholder determined the line of private property ownership by reproducing a boundary survey attached to the individual deeds conveying the additional parcels to the Petitioners. He testified that he was confident that the topographical survey he prepared accurately represented the most easterly boundary of the Petitioners' ownership. The elevation of the line of private ownership as depicted on the survey prepared by Mr. Burkholder ranges from a low of approximately 34.5 to 35.2. The elevation of the line labeled "top of bank" ranges from a high of 35.6 to a low of 34.4. The elevation of the water in Lake No. 7 would be controlled by the elevation of the modified control structure which is proposed to be set at elevation 33.6. After modification of the surface water management system to retain the 100-year storm event, at no time would water levels in the lake rise above the existing elevation of the "top of bank." The Petitioners testified that they believed that they owned to the water's edge or edge of the lake, but Mr. Burkholder testified that a property boundary could not be determined based on an elevation depicting the water's edge because that line would change as the level of the water rose and fell. The Petitioners also presented evidence that the developer's attorney made representations to them that their ownership extended to the "approximate high water line." But there appears to be no such thing as an "approximate high water line" in surveying terms. Where the boundary of a lake is depicted on a survey it generally is depicted from top of bank to top of bank. In any event, the legal descriptions of the parcels conveyed to the Petitioners were not based on a reference to either a water line or the water's edge or the lake at all. Instead, the legal descriptions were based solely on a metes and bounds description off the rear of the residential lots. Notwithstanding some contrary evidence, if the Petitioners owned to the water's edge, such ownership would require the Petitioners to consent to or join in the amended application for the modification of the Club's surface water management permit. Information regarding the ownership or control and the legal availability of the receiving water system is required as part of the contents of an application under Rule 40D-4.101(2)(d)6. and 7., Florida Administrative Code. The amended application requires the ability to "spread" Lake 7 in the direction of the Petitioners' property. If the Petitioners own the property on which the Club intends to "spread" Lake 7 in order to make the amended application work, the Petitioners must consent or join. The issue of the legal ownership and control of the Petitioners and the Club currently is in litigation in state circuit court. If the state circuit court determines that the easterly boundary of the "A" parcels lies to the east of the "top of bank," consideration would have to be given to modifying any permit issued to the Club to insure that the designed "spread" of Lake 7 in a storm event up to and including a 100-year storm event does not encroach on the Petitioners' property. District Permit Requirements The District has never before processed an application for a surface water management permit allowing commingling of storm water and reuse water. The District applied Chapter 40D-4, Florida Administrative Code, in reviewing the Club's permit application. There are no specific provisions in Rule 40D-4 or the District's Basis of Review for Surface Water Management Permit Applications that address the commingling of stormwater and reuse water; on the other hand, no rules of the District prohibit the introduction of other types of water into a stormwater treatment pond so long as the requirements of Rule 40D-4 are met. The District has the authority to allow stormwater and reuse water to be commingled. Section 40D-4.301, Florida Administrative Code, contains the conditions for issuance of a surface water management permit. Permitting Criteria In order to obtain a surface water management permit to commingle stormwater and reuse water in Lake 7, the Club must provide reasonable assurances that the proposed modifications to its existing system will provide adequate flood control and drainage; not cause adverse water quality and quantity impacts on receiving waters and adjacent lands; not result in a violation of surface water quality standards; not cause adverse impacts on surface and groundwater levels and flows; not diminish the capability of the lake to fluctuate through the full range established for it in Chapter 40D-8, Florida Administrative Code; not cause adverse environmental impacts to wetlands, fish and wildlife or other natural resources; be effectively operated and maintained; not adversely affect public health and safety; be consistent with other public agency's requirements; not otherwise be harmful to water resources of the District; and not be against public policy. No surface or groundwater levels or flows have been set for this area of the District, so that permit criterion is not applicable to the Club's application. The Club's application will not impact wetlands or fish and wildlife associated with wetlands as described in F.A.C. Rule 40D-4.301(1)(f). There are no wetlands regulated by the District in the project site. The Club has submitted to the District an operation and maintenance plan for the modified surface water management system. The operation and maintenance plan is in compliance with the District's permitting criteria contained in Rule 40D-4.301(1)(g). The District's regulation with respect to the requirement that a project not adversely affect the public health and safety is based on the specific requirements of Chapter 40D-4, Florida Administrative Code, and the Club has complied with this criterion. The permitting criterion that a project must be consistent with the requirements of other public agencies was met by inclusion in the permit of Special Conditions Nos. 5 and 6, Limiting Condition No. 3 and Standard Condition No. 3, which require that the surface water management permit be modified if necessary to comply with modifications imposed by other public agencies. The District's regulation with respect to the requirement that a project not otherwise be harmful to the water resources within the District is based on the specific requirements of Chapter 40D-4, Florida Administrative Code, and the Club has complied with this criterion. The District's regulation with respect to the requirement that a project may not be against public policy is based on the specific requirements of Chapter 40D-4, Florida Administrative Code, and the Club has complied with that criterion. The project will not have an adverse impact on water quality or quantity in receiving waters or adjacent lands. Under the District's regulations, the project would not be permittable if it caused flooding on property owned by other persons. Two concerns regarding off-site flooding were raised by Petitioners: first, the potential for flooding of the Petitioners' property; and, second, the potential for flooding of secondary systems connecting to Lake No. 7 such as private roads in the development. The project would violate the requirements of Section 40D-4.301(1)(a), Florida Administrative Code, which requires that a proposed project provide adequate flood protection and drainage, if raising the weir and berm elevation to 33.6 would cause the level of water in Lake No. 7 to move laterally up the bank and encroach on property owned by Petitioners. However, the Club has given reasonable assurances that the Petitioners own only to the "top of bank" and that raising the weir elevation to 33.6 would not cause water levels to rise above the "top of bank" of the lake. If it is determined in pending state circuit court proceedings that the Petitioners own beyond the "top of bank," any permit for the Club's project might have to be modified to avoid flooding the Petitioners' property. With respect to potential flooding of secondary systems, such as adjacent roadways, raising the elevation of water in Lake No. 7 would decrease the capacity of the storm sewers draining into the Lake. However, the proposed modifications would not increase the area of impervious surface in the drainage basin or decrease the size of the lake, and water levels in the roadways probably would not rise much higher than under present circumstances. The existing storm sewer system is only designed for a 10-year storm event, so the supplemental effect on roadway flooding from retaining a 100-year storm event in Lake No. 7 probably would be negligible. The Club gave reasonable assurances that any increase in water levels on the roadways from the proposed modifications would not be considered a significant adverse effect because it still would not affect public access. Sarasota County's land development regulations allow flooding in streets of up to 12 inches for a 100-year storm event, nine inches for a 25-year storm event, and six inches for a 10-year storm event. No portion of the proposed project area is within the 100-year floodplain. The project will not have an adverse effect on water quantity attenuation or cause flooding of the Petitioners' property or secondary systems, such as adjacent roadways. Petitioners have protested the effect that this project will have on water quality within Lake No. 7, itself. Surface water quality standards do not apply within a stormwater pond. Stormwater ponds are essentially pollution sinks intended to receive polluted runoff. Where there is no discharge from a pond, water quality treatment is irrelevant. Lake 7 is not a "water resource within the District" pursuant to Section 40D-4.301(1)(j), Florida Administrative Code, and potential impact on water quality in Lake No. 7 should not be considered. Section 40D-4.301(1)(j) limits the issues to be considered by the District to downstream water quality, water quantity, floodplain impacts, and wetlands impacts. The commingling of wastewater effluent treated to a level of advanced secondary or advanced waste treatment (reuse water) would improve water quality within a stormwater treatment pond at least 90 to 95 percent of the time. Stormwater is very low quality compared to reuse water. In most respects, reuse water also will be better quality than the well water presently being used to augment the pond. It is expected to be better quality than unimpacted water in the receiving waterbody with respect to nitrogen content and only slightly worse with respect to phosphorus content. The addition of reuse water should not promote more algal growth; rather, it should reduce the likelihood of algal growth. It also should not increase the incidences of fish kills in Lake 7. Nor should it alter the nutrient concentrations in Lake 7 so as to result in an imbalance of the natural population of aquatic flora and fauna. In the draft permit originally proposed to be issued to the Club, permit conditions required that water quality be monitored at the point of discharge to waters of the state. This requirement was eliminated from the revised permit as the District determined that it was not necessary in light of the modification of the system to retain the 100-year storm event. The subject design does not account for recovery of the water quality treatment volume within a specified period of time. However, there is no such requirement in District rules when a pond entirely retains the 100-year storm event, as is the case with this project. Even if there were a discharge from the surface water management system in a storm event up to and including a 100-year storm event, the Club gave reasonable assurances that water quality standards in the receiving waterbody would not be violated because of the effects of dilution. This project will not cause discharges which result in any violations of applicable state water quality standards for surface waters of the state. Based on a number of factors, including the peak rate factor, the curve number and the seasonal high water elevation, the water level in Lake 7 would reach an elevation of 33.57 if a 100-year storm event occurs. This results in the retention of the 100-year storm in Lake 7. The District only considers the 100-year storm event, by itself. It does not consider other rainfall events before or after it. However, the District does presume that ponds are at their seasonal high water level when the 100-year storm event occurs and that the ground is saturated. With respect to the seasonal high water level, there was substantial conflicting testimony. The Club's consultant used a seasonal high water level of 31.0' for Lake No. 7 in his calculations. This was based on a geotechnical engineering report prepared by Ardaman & Associates. A seasonal high water elevation of 31.0' was also used in the original permit application in 1985. In concluding that the seasonal high water level should be 31.0, the Ardaman report relied on several assumptions, including plugging of the underdrain and overflow weir and no discharges into or pumping out of the lake. These assumptions were made to establish an historical water level. The Petitioners' consultant disputed the determination in the Ardaman report that the seasonal high for Lake No. 7 was 31 on the grounds that the report indicated groundwater levels of 32.8 on three sides of the lake. He also felt that water levels would rise in the lake over time as a result of it being, allegedly, a closed system. While he did not have an opinion as to what the appropriate seasonal high should be, he felt it would be higher than 31 but lower than 32.8. However, he did no modeling with respect to calculating a seasonal high water level and would normally rely on a geotechnical engineer, such as Ardaman & Associates, to calculate seasonal high water levels. The District generally does not receive information as extensive and detailed as that included in the Ardaman report when it reviews permit applications. Among other things, the Ardaman report indicates a gradient across Lake No. 7 which makes the determination of the seasonal high for the lake difficult. The groundwater flow gradient results from the fact that the elevation of Lake No. 6 is approximately three feet lower than the elevation in Lake No. 7. The elevation determined by Ardaman may well be conservative in that the seasonal high of 31 is above the midpoint of the gradient. Although Lake 7 will be designed as an essentially closed system, it will have inflow from rainfall, surface runoff, introduction of reuse water and groundwater inflow, and outflows by way of evapotranspiration, withdrawal for irrigation purposes, and groundwater outflows. To alleviate any concerns about the validity of the seasonal high, it would be reasonable to include a permit condition requiring the Club to monitor the water level in Lake 7 on a daily basis, using staff gauges, after modification of the control structure. If such monitoring indicated that the seasonal high water level exceeds 31.0, the District could consider options to address that situation, including reducing the level at which reuse water is introduced into the lake or requiring water quality monitoring at the point of discharge to receiving waters. Groundwater quality is regulated by the Department of Environmental Protection, not by the District. The DEP permit issued to Sarasota County for disposal of reuse water at the Club golf course requires the installation of two groundwater monitoring wells, one in fairly close proximity to Lake No. 7. The Overlooked Pond There is a small retention pond northwest of Lake 7, near lot 113. Neither the Club nor the District considered the effect of the Club's late modification of its application on the retention pond northwest of Lake 7 and adjacent properties. Lake 7 and the retention pond to its northwest are connected by an equalizer pipe. As a result, water levels in the pond will be affected by water levels in Lake 7. There was no evidence as to the elevations of the banks of the retention pond. There was no evidence as to whether the modifications to the Club's application will result in flooding of properties adjacent to the pond. There was no evidence that the Club owns or controls the retention pond or the properties adjacent to it that might be affected by flooding that might result from the modifications to the Club's application.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Southwest Florida Water Management District enter a final order denying the Club's amended application. RECOMMENDED this 19th day of October, 1995, in Tallahassee, Florida. J. LAWRENCE JOHNSTON Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 19th day of October, 1995. APPENDIX TO RECOMMENDED ORDER, CASE NO. 95-2196 To comply with the requirements of Section 120.59(2), Fla. Stat. (1993), the following rulings are made on the parties' proposed findings of fact: Petitioners' Proposed Findings of Fact. 1.-2. Accepted and incorporated. Accepted and incorporated to the extent not subordinate or unnecessary. However, there was other evidence from which it can be determined that Lake 7 is part of the Club's lease. Accepted and incorporated. However, there was other evidence from which it can be determined that Lake 7 is part of the Club's lease and from which the western extent of the Club's leasehold interests in Lake 7 can be determined. Accepted and incorporated. But the topographic survey, together with other evidence, does show the eastern extent of the Petitioners' property in relation to the "top of bank" of Lake 7 and the western extent of the Club's leasehold interests in Lake 7. Rejected as contrary to the greater weight of the evidence that uses must be "specifically authorized" in that the lease authorizes the use of the premises for a "golf course," which is presumed to include uses inherent to the operation of a golf course that may not be further specified in the lease, such as drainage facilities, like Lake 7, and facilities for irrigation of the golf course. Otherwise, accepted and incorporated to the extent not subordinate or unnecessary. Rejected as contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Rejected as contrary to the greater weight of the evidence that the Club does not pay for the maintenance of Lake 7, at least as between the Club and its lessor, which is the subject of the pertinent lease provision. (There was evidence as to a dispute between the Club and the Petitioners, or at least some of them, as to who is responsible for maintenance of land in the vicinity of the western extent of Lake 7 and the eastern extent of the Petitioners' property. Rejected as contrary to the greater weight of the evidence. Rejected as contrary to the greater weight of the evidence to the extent that there are "A" parcels between lots 115 through 120 and Lake 7. Otherwise, accepted and incorporated. Accepted and incorporated. Not clear whether all of the activities listed in the second sentence are done in the entire area up to the water's edge but, otherwise, accepted and incorporated. Accepted, but subordinate to facts contrary to those found, and unnecessary. Accepted; subordinate to facts found. Rejected. The intent of the parties is not clear and is the subject of litigation in state circuit court. 17.-18. Accepted that some probably used the words "to the water's edge"; others may have said "to the lake" or "to the approximate high water line." Regardless of what they said, the legal consequences are being litigated in state circuit court. Subordinate to facts contrary to those found, and unnecessary. 19.-20. Accepted and incorporated to the extent not subordinate or unnecessary.. Last sentence, accepted but subordinate and unnecessary. The rest is rejected as contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. The evidence was sufficient to place on Exhibit M-16 the boundary lines of the "A" parcels, as depicted on the Alberti boundary survey that was attached to the individual deeds to all of the "A" parcels, in relation to the "top of bank" of Lake 7 and other topographical features depicted on Exhibit M-16. The 0.679 acre total for the "A" parcels was merely transcribed from the Alberti boundary survey (probably incorrectly, as the boundary survey seems to indicate the acreage to be 0.674, plus or minus.) Rejected as contrary to the greater weight of the evidence. The modification itself would not cause the water level to rise. If, due to the combined influence of all the pertinent factors, the water level in Lake 7 rises, it will spread more than before the modifications, up to a maximum spread of approximately ten feet. Rejected as contrary to the greater weight of the evidence. The Club gave reasonable assurances that the spread would be contained within its leasehold interest. However, consideration would have to be given to modifying the permit if the state circuit court determines in the pending litigation that the easterly boundary of the "A" parcels lies to the east of the "top of bank." Accepted and incorporated to the extent not conclusion of law. Accepted. Self-evident and unnecessary. Accepted and incorporated. Accepted, but subordinate, and unnecessary. Accepted and incorporated. Rejected as contrary to the greater weight of the evidence. It does not prohibit it; it just does not authorize it. It provides that authorization may be obtained by permit modification. Accepted and incorporated to the extent not subordinate or unnecessary. 32.-36. Accepted but subordinate and unnecessary. (Evidence was presented at final hearing.) 37. Rejected as contrary to the greater weight of the evidence that discharges will be "likely." (Accepted and incorporated that no discharges are expected as a result of storm events up to and including a 100-year storm event unless preceding conditions predispose the system to discharge during a 100-year storm event.) 38.-39. Accepted but subordinate and unnecessary. (As for 39., very little construction will be required for the proposed project.) Rejected as contrary to the greater weight of the evidence. First, Lake 7 will not be "maintained" at 31'; rather, when it falls below 30.5', a half inch will be added. Second, it is not clear that the Ardaman report established an "artificially low seasonal high water level." (There is a hydraulic gradient across Lake 7 from east to west, approximately. The Ardaman report assumed no flow into or out of Lake 7; it also assumed no pumpage into or out of the lake.) Rejected as contrary to the greater weight of the evidence that it is based "solely" on that assumption. Accepted and incorporated that it is based on that and on other assumptions. Accepted and incorporated. Accepted but subordinate and unnecessary. (Evidence was presented at final hearing.) Rejected as not supported by evidence. Rejected as contrary to the greater weight of the evidence to the extent that the impact is obvious--the water level in the pond will be approximately equal to the water level in Lake 7. Rejected as contrary to the greater weight of the evidence. The modification itself would not cause the water level to rise. If, due to the combined influence of all the pertinent factors, the water level in Lake 7 rises, so will the water level in the pond. 47.-48. Accepted and incorporated. 49.-50. Accepted but subordinate and unnecessary. 51.-52. Accepted and incorporated. Respondents' Proposed Findings of Fact. 1.-7. Accepted and incorporated. 8.

Findings Of Fact Background On January 29, 1981 respondent/applicant, George H. Hodges, Jr. (applicant or Hodges), filed application number 16 39644 with respondent, Department of Environmenta1 Regulation_ (DER), seeking a dredge and fill permit to generally authorize the excavation of 26,000 cubic yards of material from a 3,700 foot portion of an existing channel (Old Pablo Creek) just west of the Intracoastal Waterway (ICW) in Jacksonville, Florida. The channel then proposed was a straight channel along the northern boundary of his property. Hodges also sought to construct two boat slips, three floating docks, an 850 foot vertical bulkhead adjacent to the docks, and to dispose of all dredged material in a diked upland site. Thereafter, DER informally advised applicant that it intended to deny the application for various reasons, including the fact that the dredging would eliminate .75 acres of marsh and wetlands. After receiving this advice, Hodges proposed a series of amendments to his application in 1984 and 1985 in an effort to counter and satisfy DER's objections. The final amendment was made on September 10, 1985. As finally amended, Hodges proposed to confine all dredging to existing salt channels, thereby eliminating the objection that adjacent marshes would be destroyed. Applicant also proposed to restrict his dredging to only 2,250 feet along the northern portion of Old Pablo Creek and to remove 29,250 cubic yards of fill (silt) and sand and place the same in a 12.5 acre upland spoil site. By proposed agency action issued on February 28, 1985, DER announced it intended to issue the requested permit. This prompted a protest and request for hearing from petitioner, Jacksonville Shipyards, Inc. (JSI), which owns and operates a ship repair facility on the ICW just south of the proposed project. In its petition, JSI generally alleged that (a) Hodges had failed to give reasonable assurances that water quality standards would not be violated, (b) the project would adversely affect its property, (c) the project would have an adverse effect on the conservation of fish and wildlife, (d) the project would cause harmful erosion or shoaling, (e) DER failed to consider the long-term effect of the project on marine productivity and the cumulative impact of the project, and (f) the proposed vertical bulkhead did not meet statutory requirements. The Project The project site is a shallow horseshoe shaped creek approximately 3,700 feet in length which meanders through a vegetated salt marsh just west of the ICW in Duval County, Florida. Both ends of the creek connect into the ICW. The site is approximately one-half mile north of the bridge on Atlantic Boulevard which crosses the ICW. The ICW is a man-made channel constructed by the U. S. Corps of Engineers which runs in a north-south direction just east of the project site. It is commonly referred to as Pablo Creek. The channel or creek in which the dredging will occur is known as Old Pablo Creek (creek). An excellent aerial view of the entire area is shown in petitioner's exhibit 4 received in evidence. The creek is a predominately marine water classified as a Class III water of the State. Accordingly, it is subject to DER's regulatory jurisdiction. For purposes of this hearing, the parties have referred to the upper and lower portions of the creek as the northern and southern portions, respectively. Hodges intends to dredge the northern portion of the creek, which measures approximately 2250 feet in length from the ICW to a bend at its western end which crosses Hodges' property and where a residential site is located. According to Hodge's affidavit of ownership, he is the "fee interest owner of adjoining lands except for the dredge channel which is owned by the State of Florida". He acknowledged, however, that the residential site is owned by his superintendent, and that the marshes adjoining the most southern bend in the northern portion of the creek, and the southern portion of the creek, are owned by JSI. Except for the cleared residential site at its western end, the creek is surrounded by vegetation and salt marshes. The vegetated portion of the marsh is marked by a clearly delineated edge which separates it from the creek bottom. The dominant species of vegetation in the marsh are Juncus and Spartina. The marsh serves as a habitat and breeding ground for numerous species, including fiddler crabs, mussels, barnacles, mollusks, faunal communities and gastropods. In addition, the marsh is beneficial because of its biotic productivity and entrapment of nutrients and sediments. For this reason, the habitat should be maintained. Some forty years ago, the portion of the creek that Hodges intends to dredge was eight to twelve feet deep. However, dredging of the ICW by the Corps of Engineers and the placement of fill at the site of the Atlantic Boulevard Bridge have contributed to the shallowing of the creek over time. Today, portions of the creek are exposed and impassable under low tide conditions. Indeed, many parts of the creek are dry during the low tide phase of the ICW. At high tide, the creek is flooded to an approximate depth of four feet. Hodges proposes to dredge the creek channel to a uniform depth of five feet below mean low water (MLW) with side slopes at a 3:1 ratio to restore navigational access from his upland property to the ICW. He has represented that his use of the channel will be restricted to one, or possibly two, small boats for personal use and enjoyment. When completed, the creek channel will have a depth of nine feet at high tide, or an average depth of seven feet over a diurnal cycle. In his amended application, Hodges proposed to confine his dredging to existing creek channels, and to not disturb the actual body of the salt marsh or the vegetation bordering the creek. It is noted that there is no vegetation growing in the existing creek bottom. However, at hearing he conceded that dredging "may include some minor removal of isolated patches of grass growing in the creek channel". One such patch of grass lies in the elbow of the canal which reaches south of Hodges' property, a patch separated from the main body of the marsh by a five foot wide slough deep enough to be navigated at high tide. Hodges estimates this patch of grass to be less than 1/100 of an acre in size (10' x 40') and maintains the effect of its removal would be negligible. The excavation will be effected by means of a Mud Cat hydraulic dredge which operates by suctioning the sediment and water into a pipe. The dredge material (sediment/water mixture) will then be pumped into a series of containment cells on a 12.5 acre upland spoil site that lies approximately one-half mile northeast of the project. Any discharge from the spoil site will be to Greenfield Creek, a tidally influenced creek connected to the St. Johns River. The natural grade of the existing creek bottom is at or below the mean low water datum. At high tide the existing creek is 4.3 feet deep at its deepest point and gradually slopes upward to a depth of 2.4 feet near the marsh. The elevation of the creek where it meets the marsh is close to mean high water. Even so, the channel width does not always correspond with the mean high water line boundaries of the creek, and creek waters sometimes inundate and extend back into the marsh at high tide. Because Old Pablo Creek is tidally influenced, any water quality violations in the northern portion of the creek can be expected to also have an adverse effect in the southern portion as well. Creek Width Petitioner has raised the issue of whether the creek is as wide as Hodges represents it to be on the drawings attached to the amended application. This is significant since (a) the engineering plans are based upon the assumption that the measurements in the application are correct, (b) the proposed dimensions (depth and side slopes) of the new channel are dependent upon the existing creek having a minimum width of from sixty to eighty feet, as represented by Hodges, and (c) any excavation outside of the existing channel will result in the removal (destruction) of vegetation and marsh. In his application, Hodges reflects the top width of the creek to be sixty to eighty feet, which width will enable him to dredge the channel to an average depth of five feet below MLW, and maintain a side slope ratio of 3:1. This ratio is necessary because of the composition of the sediment in the creek. The minimum top width required to excavate a channel with 3:1 side slopes to a depth of five feet below MLW is fifty- four feet. Petitioner's exhibit 4 identifies five points along the eastern half of the northern portion which have been measured by the parties to determine the actual width of the creek. Although only five points were measured, it may be inferred that these distances are representative of the creek's width throughout its eastern half. At points five through eight, the widths are forty-nine, thirty-five, fifty and fifty feet, respectively, which are less than the measurements contained in the application. If the channel is constructed with the minimum top width (54 feet) required to have 3:1 side slopes, it will result in the elimination of 6 feet of marsh at point 5, 19.5 feet of marsh at point 6, and 4.1 feet of marsh at both points 7 and 8. This equates to the elimination of approximately .33 acres of marsh. Since the above measurements are representative of the eastern half of the northern portion, other areas of vegetation, albeit in unknown proportions, would also have to eliminated. If, for example, applicant attempts to construct a channel within the confines of the portion of the creek that has a top width of only thirty-five feet (point 6), the maximum channel that could be constructed would be V-shaped with a depth of one foot at low tide. Assuming the remaining part of the channel was excavated to -5' MLW, a stagnant area would develop in this portion of the channel and adversely affect water quality. However, to counter the problem at point 6, Hodges intends to remove one patch of grass 10' by 40' in size to achieve the desired width. Any adverse effects on the adjacent marsh at that particular point would be negligible. Because the estimated creek width is not accurate, even the agency now concedes the engineering plans are no longer useful. As a condition to the issuance of a permit, DER has suggested that Hodges be required to submit new certified engineering drawings depicting the proposed cross-section of the channel. It also suggests that the proposed cross-section comply with the top-widths depicted in applicant's exhibit 53, and depict side-slopes of three to one. It further suggests that a condition for the issuance of any permit be a requirement that the 3:1 ratio be maintained, and that other than point 6, no other grass be removed. Finally, the agency proposes that if the new plans and conditions do not permit a -5 MLW depth, the proposed depth be reduced accordingly. However, the evidence supports a finding that either vegetation must be removed at various points along the eastern half of the creek in order to maintain a 3:1 ratio for side slopes, or the depth must be reduced. By reducing the depth at certain points, stagnant areas in the creek will develop, thereby adversely affecting the quality of the water. Further, as noted hereinafter, the validity of the flushing analysis performed by applicant's experts rests upon the assumption that a -5' MLW uniform depth will be used. Finally, the applicant has not given reasonable assurance that the marsh and habitat will not be adversely affected by the elimination of the vegetation which is necessary to achieve the desired depth and concomitant 3:1 ratio. Therefore, the alternative conditions suggested by DER are neither reasonable or appropriate. The Spoil Area The spoil area to be used by applicant is a 12.5 acre upland disposal site approximately one-half mile northeast of Hodges' property. Applicant does not own the upland spoil site but has obtained easements from the owner which expire in March, 1987. In other words, he must complete all work on the project by that date or lose access to the property. The proposed spoil site is completely diked, and is sectioned off into three sections by interior dikes with overflow pipes. Internal baffles and silt fences are also designed into the area. Uncontradicted testimony established that the spoil area is "unusually well designed". Any discharge from the spoil area will be to Greenfield Creek, a tidally influenced creek connected to the St. Johns River. Discharge, if any, will be outfall from an overflow structure in the third section of the spoil area to a dump area land then by sheet flow to salt marshes adjacent to Greenfield Creek. The vegetation in Greenfield Creek consists of a salt marsh expanse of Spartina alterniTlora and Juncus roemerianus. Both species survive in and are indicative of regular introduction of saline waters, and show high tolerance to varying salinity levels. If saline waters from Old Pablo Creek were introduced into Greenfield Creek, it would have no adverse impact on the Greenfield Creek ecosystem. The size of the site was originally designed for a project of 100,000 cubic yards. The site will retain all |effluent from the dredging. The expected total effluent, both sediment and water, is roughly 5.3 million cubic feet of material, assuming a ratio of 6.7 cubic feet of water for each |cubic foot of sediment dredged. This is slightly lower than the 5.4 million cubic feet total capacity of the site. The supernatant from the discharge being deposited into the first cell of the spoil area will only flow into the next cell when the first cell fills and the level of the supernatant rises above the top of the vertical drain pipe overflow structure. If rainfall events cause the cells to fill with water during dredging and discharge operations, the discharge to the next cell or to Greenfield Creek will be primarily fresh water. This will occur because introduction of fresh rainwater into the brackish water from the dredge area will cause stratification, and the fresh rainwater will form a layer on top that will flow into the overflow structure. Turbidity Effects In removing the mud bottom from the creek to a depth of -5' MLW, some turbidity will occur. This is a natural by- product of using the hydraulic dredge. However, the amount of turbidity, and its effect on the waters at the dredge site and discharge point, are in issue. State water quality standards prohibit the discharge of water with a turbidity level greater than twenty-nine nephelometric units (NTU's) above the background levels of the receiving waters. The evidence indicates that the background turbidity levels at the creek are now in the range of ten to twenty NTV's. Excessive levels can result in adverse effects on local biota such as decreasing productivity by reducing light penetration. Excessive turbidity can also be expected to suffocate organisms. The area to be dredged contains sediment deposited from the surrounding salt marsh and carried in from the ICW. The sediment is composed of 14% clay, with the remainder being sand and silt. This was confirmed by a laboratory analysis conducted by JSI. As a general rule, the coarser the material, the faster it tends to settle out thereby creating less turbidity problems. Therefore, sand, which is of a grain size, can be expected to settle out quickly while silt takes somewhat longer. However, clay size particles are much smaller than silt and do not settle out as easily. Applicant made no laboratory analysis of sediment and consequently he erroneously assumed the mud to be sand and silt, and did not take the clay particles into account. The dredging in the creek will cause the turbidity levels to rise to 150 NTU's. However, the placement of a turbidity screen at the entrance to the ICW will prevent the release of this turbidity into that water body. Therefore, if a permit is issued, such screens should be used by Hodges at the dredge site. At the spoil site, clay size particles will also be included in the matter pumped for discharge. If these particles do not settle out, or are not treated, their discharge into Greenfield Creek (a jurisdictional water) will cause violations of the turbidity standards. To counter their effects, flocculants (chemicals) should be added when necessary to the confined material to aid the particles in settling. If a permit is issued, this should be made a condition in the permit. Dissolved Oxygen Impacts The dissolved oxygen (DO) levels in the creek fluctuate on a daily and seasonal basis. As a general rule, DO levels tend to be lower in warmer weather and during the early morning hours. Therefore, a "worst case" situation will generally occur in the summer months in the early part of the day. State water quality standards contained in Rule 17- 3.121(13), F.A.C., provide that in predominately marine waters, the concentrations of DO "shall not average less than 5 milligrams per liter in a 24-hour period and shall never be less than 4 milligrams per liter." Sampling conducted by petitioner at 5:00 a.m. in early July, 1986 during high tide revealed readings ranging from 3.06 mg/1 in the western portion of the creek to 4.59 mg/1 at the mouth of the creek. Dissolved oxygen levels in the ICW ranged from 3.94 to 4.68 mg/1. Hodges also sampled the creek and ICW in the late morning or early afternoon on August 6,1986 and determined DO levels to be 4.8 mg/1 in the creek and 5.8 mg/1 in the ICW. Testing at that hour of the day produced higher values than those found by JSI. The readings collectively confirm that DO levels in the creek are approximately 1.0 mg/1 less than the DO levels in the ICW. This deficit is primarily caused by the high oxygen demand exerted by the adjacent marsh and muds in the creek. This situation will not be changed by the dredging. The flushing time of the creek channel is an important factor in predicting post-dredging impacts on water quality. Flushing time determines how rapidly waters of the ICW will exchange and mix with the water in the creek channel. Both Hodges and JSI conducted tidal prism studies to determine how many tidal cycles would be required to flush a hypothetical pollutant to 10% of its initial concentration. Under worst case conditions, the channel is expected after dredging to flush every 3 to 4 tidal cycles or 1.6 days. Under more favorable conditions, the creek is expected to flush every 2 to 3 tidal cycles. This compares with the current system which flushes almost 100% every tidal cycle or once every twelve hours. The increased flushing time is due to the significantly greater volume of water that will enter the creek channel after dredging. Because of increased channel depths, the water will move at a slower velocity. Therefore, the oxygen consuming components have a longer period of time to react in the water column. This in turn will cause reductions in DO levels of between .7 mg/l and 1.5 mg/l in the creek. This was confirmed through tidal prism modeling performed by JSI. In this regard, it is noted that JSI's modeling was more sophisticated, better calibrated, and its assumptions were more accurate and reasonable. Consequently, its testing results are considered to be more reliable and persuasive than that of applicant. It must also be recognized that the deepening of those areas that are currently exposed at low tide will allow water to move more easily through the channel and remove some oxygen demanding sediments that now draw from a shallow water column. This will tend to have a beneficial effect on water quality. However, the overall impact of these beneficial effects is unknown, and it was not demonstrated that the otherwise adverse effect on DO will be offset or minimized by the unmeasured impact of deepening the shallow areas. Therefore, applicant has not given reasonable assurance that water quality standards will not be violated by the project. At the same time, it must be further noted that a reduction in the channel depth due to the smaller width of the creek will alter the results of the tidal prism studies, as well as negate some of the beneficial effects caused by deepening the shallow portions of the channel. To what extent the studies are changed, or benefits will be reduced, is not of record. Other Effects of Project As noted earlier, Hodges intends to use one or two boats on the deepened channel. The use of the boats will not introduce pollutants in any significant quantity. Hodges proposes to construct his docks and place rip- rap on the northern side of the widest portion of the creek channel. Little, if any, vegetation will be eliminated by these activities. The use of rip-rap for the construction of the bulkhead is the most environmentally sound means of bulkheading, and will stabilize the shoreline as well as provide habitat for aquatic organisms. The dredging of the creek channel will improve the navigability of the creek, and permit the use of boats in areas where access is now impossible under low-tide conditions. In addition, the sharp bends in the creek will prevent the operation of boats at high speeds. JSI's concern that boats may run aground once they leave the northern portion and enter the southern portion is not meritorious since few, if any, are expected to use the latter part of the creek, and the sharp bends will force boaters to operate at low speeds. Shoaling or erosion of the southern portion will not result from the proposed activities. Indeed, an increased flushing and introduction of new flow into the system may benefit the northern portion. Any situation occurring in that part of the creek should not exceed the rate of siltation occurring under current conditions. The benthic organisms which populate the bottom of Old Pablo Creek include crabs, mussels, barnacles and other species normally associated with estuarine systems. The removal of the mud bottom in the dredging operation may remove some of these organisms. However, this should not significantly change the habitat of these benthic organisms. Rapid recolonization by these species would be expected with recolonization substantially underway within forty-eight hours
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that application number 16-39644 of George H. Hodges, Jr. for a dredge and fill permit be DENIED. DONE and ORDERED this 2nd day of December, 1986 in Tallahassee, Florida. DONALD R. ALEXANDER, Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32399 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 2nd day of December, 1986.
The Issue The issue in this case is whether the Department of Environmental Regulation (Department) should issue permit number 1C53-154132 to the applicant, IMC Fertilizer, Inc. (IMCF), for the modification of an existing industrial wastewater management system by constructing additional phosphogypsum storage capacity, or whether the permit should be denied as maintained by Manasota- 88 (Petitioner).
Findings Of Fact The Parties IMCF is a Delaware Corporation properly registered to conduct business in the State of Florida, which owns real property known as the New Wales Chemical Complex located in western Polk County, Florida, approximately 5 miles southwest of Mulberry, l mile south of State Road 640, and east of the Hillsborough-Polk County line. The New Wales Chemical Complex began operations in April, 1975, and consists of approximately 1600 acres which are located within a 17,000 acre tract owned by IMCF known as the "Kingsford Mine". Generally, the distance from the New Wales Complex boundary to the Kings ford Mine property boundary is from one to two miles. IMCF produces phosphoric acid and other phosphate-related products, including animal feed ingredients, and stores the by-product called phosphogypsum within a gypsum stack or pile. The Department is the administrative agency of the State of Florida having the power and duty to control and prohibit pollution of air and water in accordance with Chapter 403, Florida Statutes, and Chapter 17, Florida Administrative Code. The Department has the authority to consider and act upon the permit application at issue in this case. Petitioner is a public interest environmental protection organization incorporated under the laws of the State of Florida as a not-for-profit corporation, is headquartered in Palmetto, Florida, and is a citizen of the State of Florida for purposes of Section 403.412(5), Florida Statutes. Petitioner has standing to maintain this action. The Application Process On or about August 31, 1988, IMCF filed with the Department an application for a permit to modify its industrial wastewater management system at the New Wales Complex by constructing additional phosphogypsum storage capacity. This permit application was assigned file number 1C53-154132. The Department requested additional information from IMCF concerning this initial application on or about September 29, 1988 and December 16, 1988, and IMCF timely responded on each occasion. On or about July 3, 1989, IMCF submitted an application supplement to the Department which substantially changed the nature and scope of its original application. The project proposed by IMCF for which it has sought the permit at issue in this proceeding is described and set forth in this supplement to IMCF's original application. The Department requested additional information concerning this application supplement on or about August 2, 1989, to which IMCF timely responded. On or about November 6, 1989, the Department filed its Intent to Issue permit number 1C53-154132, and thereafter, Petitioner timely instituted this action to challenge the issuance of this permit to IMCF. The Existing Operation At its New Wales Chemical Complex, IMCF operates sulfuric acid and phosphoric acid plants, granulated triple superphosphate and granulated ammonium phosphate plants, and a uranium recovery plant. The primary raw materials used at the New Wales Complex are sulfur and phosphate rock. Sulfur is used to produce sulfuric acid, which is then used to react with phosphate rock that has been mined by IMCF. This reaction produces phosphoric acid which is then further processed into fertilizer products and animal feed ingredients. Phosphogypsum or gypsum is a byproduct from the production of phosphoric acid. Approximately five tons of gypsum are produced for every ton of phosphoric acid which is produced. Gypsum is slurried and transported to an existing gypsum stack where it is allowed to settle in settling compartments. IMCF's existing gypsum stack is approximately 132 feet high, and it is reasonably estimated that it will reach its maximum useful height of 200 feet by May, 1992, at IMCF's current phosphoric acid production rate of 1.7 million tons per year, which results in approximately 8.5 million tons of gypsum per year. As the gypsum stack grows in height, the surface area on top of the stack that is available for gypsum deposition and management decreases, and at approximately 200 feet above ground surface there will be insufficient retention time for the slurried gypsum to settle out and to be used in continued construction of the stack. Therefore, when IMCF's existing stack reaches 200 feet in height, operations at the New Wales Complex will have to cease unless an alternative gypsum storage location is authorized through the issuance of the permit sought in this proceeding. The existing gypsum stack is unlined. In addition to the storage and management of gypsum, the existing gypsum stack at the New Wales Complex is also used to store rainfall that may fall on the stack and cooling pond. This storage capability allows IMCF to avoid discharging pond water to the surface waters of the State during heavy or extended rainfalls. During low rainfall periods, stored rainwater can be used to supplement pond water, and thereby reduce IMCF's need to pump fresh water from the aquifer to meet its cooling and scrubbing needs. Additionally, during the hot summer months, the area on top of the stack is also used for cooling purposes. A cooling pond approximately 247 acres in size is located to the immediate south of the existing stack, with additional cooling channels encircling the stack on its remaining three sides. This existing, unlined cooling system encompasses a total of approximately 281 acres, and recirculates approximately 150,000 to 170,000 gallons of water per minute through this entire cooling system and back to IMCF's production plants for reuse. Approximately twelve uncapped recharge wells, each eight inches in diameter, were drilled in the area under the cooling pond during mining operations. These recharge wells were broken off during mining operations, and it is estimated that these wells have been filled to the top of the confining layer above the Floridan aquifer by sand and debris. The production of fertilizers generates heat which must be dissipated through cooling, and gasses which must be cleaned by "scrubbing" them with water. IMCF's cooling system at the New Wales Complex carries out these cooling and scrubbing functions. Pond water is used to transport gypsum in slurry from the phosphoric acid plant to the top of the gypsum stack, where it is directed to one of three settling compartments on the top of the stack. Settled gypsum is periodically dredged out, and used to build up the diked area around the edges of the stack. The slurry water is then decanted to the perimeter ditch and returned to circulation. Waters collected at the New Wales Complex which do not come in contact with fertilizer products or raw materials are collected on the site and directed to an impoundment area referred to as "A-11" for recirculation and reuse in the plant. Excess noncontact water may be periodically released to the Kings ford Mine recirculating system during heavy or extended rainfall, and is managed separately from pond water. A 90 acre emergency holding pond is located to the west of the cooling pond and to the south of the production facility. However, IMCF has never had to discharge excess pond water into this emergency area. This emergency holding pond is unlined. IMCF's existing facility is a zero discharge to surface water facility. Other phosphate companies discharge pond waters to surface waters after treatment with calcium oxide or calcium carbonate. This existing facility can also store, without surface water discharge, rainfall and other waters in excess of Departmental and federal effluent guidelines Because IMCF's existing, unlined gypsum stack and cooling pond system release some seepage to the ground water, on or about September 8, 1989, IMCF and the Department executed a Consent Agreement in OGC Case Number 89-0657 pertaining to the operation of the existing gypsum stack and cooling pond, which states in pertinent part: Cooling pond water on the Site contains concen- trations of various constituents in excess of primary drinking water standards. (Finding 4) Contaminant concentrations in groundwater samples collected from the surficial aquifer and the uppermost segment of the intermediate aquifer system at certain locations on the Site are elevated with respect to unaffected groundwater quality. Monitoring well SA-4 . . . is located approximately 400 feet from the cooling pond channel and has indicated concentration levels of certain constituents in excess of primary and secondary drinking water standards . . . Analyses from monitoring well SA-6, located 1600 feet downgradient from well SA-4, have recently indicated sulfate and TDS concentra- tion levels slightly exceeding secondary drinking water standards. Therefore, the vertical and horizontal extent of groundwater contamination and the rate and direction of contaminant transport in groundwater require additional evaluation. (Finding 5) Some evidence indicates elevated contaminant concentrations above background levels in groundwater samples collected from one of seven monitoring wells that draw water from the lower segment of the intermediate aquifer system in a location adjacent to and down- gradient from the cooling pond. Therefore, additional evaluation of the potential impact of abandoned recharge wells underlying the cooling pond is required. (Finding 6) IMCF has collected ground water quality data pursuant to the requirements of Ground Water Monitoring Plan Permit No. MP53-75181, currently in effect, as well as data in connection with this expansion project. This data indicates that two monitoring wells have been impacted by seepage from the existing gypsum stack. Well No. NWC-2-S2A, located approximately 400 feet to the west of the edge of the gypsum stack, contains ground water with elevated levels of sodium in excess of concentrations set forth in applicable ground water quality rules, and has recorded sulfate levels which exceed standards. Well No. SA-4, located approximately 700 feet west of the existing stack, reflects concentrations of sodium, gross alpha, and radium-226 in excess of concentration limits set forth in applicable rules, and has also recorded exceedences for sulfate, total dissolved solids and iron. These two wells are located within the New Wales Complex, and draw water from the upper portion of the intermediate aquifer, probably being impacted by seepage from the stack westward through this zone. In addition, data collected from IMCF monitoring well NWC-5-I4A, located immediately west of, and adjacent to, the cooling pond, show elevated levels of temporary dissolved solids, arsenic, sulfate and sodium above background levels, although the sodium concentrations do not exceed the maximum concentration limits set forth in applicable Departmental ground water quality standards. This well draws water from the major producing zone of the intermediate aquifer system. Finally, water quality impacts are shown as a result of analysis of ground water samples taken from three other wells at the New Wales Complex, wells NWC-2-S1 and NWC-2-SIA which draw water from the surficial aquifer, and well SA-6 which draws water from the uppermost portion of the intermediate aquifer system. However, based upon the evidence and analysis presented by Dr. John Garlanger, who was accepted as an expert in ground water quality impact assessment, and notwithstanding the contrary opinion expressed by Steven R. Boyes, who was accepted as an expert in hydrogeology, it is likely that these impacts come from a source other than the gypsum stack. Based in part upon the findings set forth above, the Consent Agreement provides that IMCF will implement a series of stated corrective actions, including additional monitoring activities, and that IMCF will evaluate pertinent primary and secondary drinking water standard constituents in all potentially affected aquifers within, and/or beyond, its zone of discharge. Once this is done, IMCF may be required to evaluate various remedial action alternatives, and to ultimately implement a remedial action plan. The Consent Agreement also authorizes IMCF to install a slurry wall to the north and northeast of the existing stack to limit any seepage in that area. IMCF has committed to the Department that if ground water quality monitoring indicates significant contamination is approaching the limits of the IMCF production plant, it will also install a slurry wall along the western edge of the plant in order to intercept any such contamination in the surficial and upper intermediate aquifer systems and contain it within IMCF's property. Dr. Garlanger performed a modeling analysis concerning the impact of the existing cooling pond and stack upon the water quality of the major producing zone of the intermediate or Floridan aquifer, given that these existing facilities will not be closed, but will remain in use in connection with the new stack for an additional twenty years beyond 1992. Based upon that analysis, it is found that any seepage through the upper confining unit from either the existing stack or pond would not cause a violation of primary or secondary drinking water quality standards. In addition, even if the twelve recharge wells underlying the cooling pond area were each leaking at the rate of one gallon per minute, which was shown to be an overestimate of any reasonable leakage rate, Dr. Garlanger concluded that insignificant impacts would result in the major producing zone of the intermediate and Floridan aquifer systems. The precise vertical or downward extent of the zone of discharge has not yet been determined for the New Wales Complex, although a zone of discharge horizontally to the IMCF property line has been established. However, the Department has reasonably concluded that the water quality impacts at the site resulting from the existing stack and cooling pond, referred to above, are not violations of IMCF's current permit, or of applicable rules and standards. The Department does not currently have sufficient information to determine what, if any, remedial action would be appropriate for impacts resulting from the existing stack and cooling pond, but this information will be developed pursuant to the Consent Agreement. The Department has not ruled out any eventual remedial action alternative, including closure of the existing gypsum stack. The Proposed Project IMCF proposes to construct an additional 415 acres of gypsum storage capacity, including permimeter ditching, in a total project area of 520 acres which will be located immediately south of, and adjacent to, the existing cooling pond that is used in connection with the existing gypsum stack or pile. It is reasonably estimated that this new stack will be in operation for twenty years. A 60-mil high density polyethylene liner is to be installed over the entire base area, and the upstream slope of the perimeter dikes. The proposed liner will be chemically and physically compatible with conditions that will be encountered in the expanded gypsum stack area, and will be of sufficient strength to prevent failure during installation and operation. Textured liner material will be used around the outer edges of the stack area underlying the projected stack slope, while smooth material will be used under the remainder of the stack. The textured material provides an additional safety factor to prevent slope stability failure. IMCF's proposed gypsum stack is designed with a factor of safety significantly greater than that which is provided in other stack projects. The liner material will be delivered to the site in sheets which will be rolled out on site, overlapped, and bonded with adjacent sheets using an extrusion-fusion welding process. IMCF will follow an extensive quality assurance and control program to insure that the contractor installing the liner follows all required procedures, including inspections and evaluations, random destructive testing, and vacuum testing of every inch of liner welds. Three concentric rings of perimeter gravel drains with polyethyline collector pipes will be installed over the liner and beneath the projected slope of the gypsum stack in order to reduce the hydraulic head on the liner and improve the stability of the stack. The materials used in the drain system will be compatible with the environment which they will encounter in the gypsum stack. IMCF proposes to separate the existing cooling pond and the proposed new gypsum stack with a 2.5 foot thick soil-bentonite slurry wall constructed along and within the entire length of the northern perimeter dike of the expansion area, and keyed approximately 30 feet into the underlying bedrock- bedclay complex. This slurry wall will provide a barrier to lateral seepage from the existing cooling pond into the expansion area, and will effectively function as a vertical liner. Materials used to construct the slurry wall will not be adversely impacted by seepage from the cooling pond. Two culverts for routing the seepage, runoff and decant water from the gypsum stack perimeter collection ditch into the existing cooling pond are to be installed. An additional syphon spillway is to be constructed at the southwest corner of the existing cooling pond and directed into the emergency holding pond. There is no proposal to cap the twelve uncapped recharge wells located under the existing cooling pond. The existing cooling and emergency holding pond will remain in operation with the new proposed gypsum stack. Gypsum will be slurried by pipeline from the phosphoric acid plant to the proposed new stack after its completion, where it will be managed in a manner similar to that practiced on the currently operating stack. The transport water will be returned to the cooling pond system for recirculation. IMCF proposes to use the top of the existing stack for the storage of rainfall and for cooling purposes during times of excessive heat. The geology of the gypsum stack expansion project site is appropriate and suitable for this proposed use, as established through an evaluation of regional and site-specific information, including prospecting data collected by IMCF prior to mining this area and geophysical logging information from wells that have been installed in the area. Site-specific geological tests performed by IMCF included the drilling and evaluation of five core holes around the area of the expansion project, and evaluation of the geological conditions encountered during the drilling of thirty-one ground water monitoring-wells installed in the vicinity of the proposed project area, and an evaluation of soil borings taken from within the project site. Surface depressions and lineaments shown on pre-mining aerial photographs of the area were also evaluated. The physical evaluation and examination of the former locations of surface depressions was conducted, as was a sinkhole probability assessment. The hydrogeology underlying the site of the proposed expansion area does not contain any features which would adversely affect the siting of the expanded stack in this proposed location. There are three major aquifer systems underlying the proposed project area, including the surficial, intermediate and Floridan aquifer system. The surficial aquifer, extending from the top of the water table to a depth of approximately 60 feet, contains overburden and sands that have replaced the original "matrix" formation of phosphate ore which has been mined. The intermediate aquifer system underlies the surficial aquifer, with its upper portion having very low permeability, extending approximately 125 feet in thickness, and containing some water bearing zones which are not laterally continuous in the project area. The major producing zone, consisting of sandy limestone material, is located in the lower portion of the intermediate aquifer. There is a confining unit approximately ten feet in thickness, known as the "Tampa clay", at the very bottom of the intermediate aquifer, separating it from the Floridan aquifer. The Floridan aquifer system is a highly productive limestone aquifer, several hundred feet in thickness, that is the primary source of municipal drinking water and industrial water supplies in the area. The preparation of the site will begin with the removal of various materials deposited in the area during mining operations which have already taken place, and the diversion of surface water from the area. The site will be dewatered by allowing water to flow from the site into other mined-out portions of the Kingsford Mine further to the south. This dewatering process will not discharge any water to the waters of the State. After dewatering, the site will be graded to remove any materials that could potentially puncture the liner. The presence of existing wells in the project site will also be addressed by IMCF as part of its site preparation activities. Thirty-eight wells were previously installed in the project area, thirty-three of which were recharge wells that were used to drain water from the surficial aquifer system down to lower aquifer systems prior to mining. Twenty of these wells have been physically located, and IMCF will insure that these wells are abandoned and plugged in accordance with currently applicable regulatory requirements. The remaining eighteen wells in the project area cannot be physically located and plugged because they have been destroyed or otherwise impacted by mining operations. IMCF will install circular concrete caps, three feet in thickness and of varying diameters, over the former locations of these wells which have been determined using an analysis and evaluation of historical surveys and aerial photography, as well as computer modeling. It was established through the testimony of Richard Fountain and Dr. Nadim Fuleihan, who were accepted as experts in geological evaluation and consultation, and civil and geotechnical engineering, respectively, that these caps will reliably encompass the locations of these eighteen former wells, and will, further, maintain the structural integrity and stability of the lined gypsum stack. IMCF has provided reasonable assurances to the Department that the construction and operation of the proposed additional gypsum stack will not result in discharges that will cause pollution in violation of statutory provisions or Departmental rules or standards designed to protect surface and ground water quality. As discussed elsewhere herein, IMCF will include an extensive groundwater quality containment/protection system in this project, the essential elements of which include the slurry wall, synthetic liner and underdrain system. Surface waters will not be adversely affected by dewatering of the project area prior to construction, nor by rainfall that strikes disturbed areas during construction due to the diversion of such waters into the Kings ford Mine water recirculation system, thereby preventing direct discharge to surface waters of the State. Construction of the new gypsum stack will increase the area at the New Wales Complex that will catch rainfall and direct it towards the pond water recirculation system. However, based on the evidence presented by Dr. Fuleihan, even under extreme rainfall conditions there is a very low probability that IMCF would have to discharge pond water from the emergency holding pond, and even under this unlikely condition, IMCF has the capability of implementing a program to treat and reuse pond water in its production processes, and will not have to discharge pond water to surface waters of the State. The proposed one layer synthetic liner which IMCF will install with the new stack can reasonably be expected to prevent pollution of the ground water which would violate applicable statutory provisions, rules or standards. It was established through the testimony and evidence presented on behalf of IMCF, and particularly the evidence presented by Dr. Fuleihan, that the proposed liner to be used by IMCF is at least five times more protective (less permeable) than clay liners, and eight times more protective (less permeable) than the design liner which would be required by the Department's policy statement concerning the lining of gypsum stack expansion projects. This project will essentially involve zero discharge to ground water due to the extremely low permeability of the liner material. Based upon the testimony of Dr. Garlanger, any impacts reasonably expected to occur through liner seepage and defects would not result in an exceedence of applicable primary drinking water quality standards at the base of the surficial aquifer underlying the gypsum stack expansion area. No impacts at all were projected at any point lateral to the edge of the gypsum stack expansion area. In accordance with the terms of the permit the Department proposes to issue, IMCF will be required to monitor ground water quality in order to demonstrate compliance with all applicable standards. IMCF has provided reasonable assurance that it can locate and cap all uncapped recharge wells in the project area, and has proposed a method for capping such wells which is appropriate, and which can reasonably be expected to be effective in preventing the intrusion of pollutants into the ground water through these presently uncapped recharge wells.
Recommendation Based upon the foregoing, it is recommended that Department enter a Final Order approving IMCF's permit application and issuing permit number 1C53-154132.

The Issue The issue is whether Respondent Koreshan Unity Foundation, Inc., is entitled to a environmental resource permit for the construction of a wooden footbridge over the Estero River east of U.S. Route 41 and authorization to obtain by easement a right to use sovereign submerged lands.
Findings Of Fact Respondent Koreshan Unity Foundation, Inc. (Koreshan) is a not-for-profit corporation dedicated to the preservation of the Koreshan heritage. Koreshan derives its heritage from a largely self-sufficient community that occupied land in south Lee County. For several years, Koreshan has owned a parcel of 14.56 acres at the southeast corner of U.S. Route 41 and the Estero River. This parcel is bounded on the south by Corkscrew Road and contains an amphitheater and historical house, midway between the river and Corkscrew Road. The south end of this parcel contains a museum and parking area with access to Corkscrew Road. The approximate dimensions of the 14.56-acre parcel are 544 feet along the river, 496 feet along Corkscrew Road, and about 1273 feet along the west and the east property lines. The west property line is U.S. Route 41. The right-of-way for U.S. Route 41 is wider at the southern two-thirds of the parcel than the northern one-third of the parcel. A sidewalk runs on the east side of U.S. Route 41 from north of the river, across the U.S. Route 41 bridge, along the west boundary of Koreshan's property, at least to an entrance near the middle of the 14.56-acre parcel. In October 1996, Koreshan acquired 8.5 acres of land at the northeast corner of the U.S. Route 41 and the river. The purpose of the acquisition was to provide parking for persons coming to Koreshan-sponsored events, such as music performances, at the 14.56-acre site. Koreshan rents a small portion of this northerly parcel to a canoe-rental business, which operates where the bridge and river meet. To assist their visitors-some of whom are elderly and disabled--in gaining access to the 14.56-acre site, on November 26, 1996, Koreshan filed an application for a permit and authorization to construct a wooden footbridge across the Estero River about 315 feet east of the U.S. Route 41 bridge. The source of the Estero River is to the east of the U.S. Route 41 bridge and the location of the proposed bridge. After passing under the U.S. Route 41 bridge, the river runs along the Koreshan state park, which is a short distance east of U.S. Route 41, before it empties into the Gulf of Mexico at Estero Bay, which is a state aquatic preserve. The portion of the river at the site of the proposed bridge is an Outstanding Florida Waterway (OFW) and a Class III water. The river is popular with canoeists and kayakers. Persons may rent canoes and kayaks at the canoe rental business operating on the 8.5-acre parcel or the Koreshan state park. Although most canoeists and kayakers proceed downstream toward the bay, a significant number go upstream past the U.S. Route 41 bridge. Upstream of the bridge, the river narrows considerably. Tidal currents reach upstream of the U.S. Route 41 bridge. At certain tides or in strong winds, navigating a canoe or kayak in this area of the river can be moderately difficult. Even experienced canoeists or kayakers may have trouble maintaining a steady course in this part of the river. Less experienced canoeists or kayakers more often have trouble staying on course and avoiding other boats, the shore, vegetation extending from the water or shoreline, or even the relatively widely spaced supports of the U.S. Route 41 bridge pilings, which are about 30 feet apart. Mean high water is at 1.11 feet National Geodetic Vertical Datum. The deck of the proposed footbridge would be 9 feet, 6 inches wide from rail to rail and 16 feet wide in total. The proposed footbridge would extend about 180 feet, spanning 84 feet of water from shore to shore. The bridge- ends would each be about 50 feet and would each slope at a rate of 1:12. The proposed footbridge would rest on nine pilings: four in the uplands and five in the submerged bottom. The elevation of the bottom of the footbridge from the water surface, at mean high water, would be 8 feet, 8 inches. The distance between the centers of the pilings would be 14 feet, and each piling would be of a minimum diameter of 8 inches. According to a special permit condition, the pilings would be treated with chromated copper arsenate, as a preservative, but they would be wrapped in impermeable plastic or PVC sleeves so as, in the words of the proposed permit, "to reduce the leaching of deleterious substances from the pilings." The proposed permit requires that the sleeves shall be installed from at least 6 inches below the level of the substrate to at least 1 foot above the seasonal highwater line and shall be maintained over the life of the facility. The proposed permit also requires that the footbridge be limited to pedestrian traffic only, except for wheelchairs. The permit requires the applicant to install concrete-filled steel posts adjacent to the bridge to prevent vehicles from using the bridge. The proposed permit requires that Koreshan grant a conservation easement for the entire riverbank running along both shorelines of Koreshan's two parcels, except for the dock and boat ramp used by the canoe-rental business. The proposed permit also requires Koreshan to plant leather fern or other wetland species on three-foot centers along the river banks along both banks for a distance of 30 feet. The proposed permit states that the project shall comply with all applicable water quality standards, including the antidegradation permitting requirements of Rule 62-4.242, Florida Administrative Code. Respondents did not raise standing as an affirmative defense. It appears that Petitioners or, in the case of corporate Petitioners, members and officers all live in the area of the Estero River and use the river regularly. For instance, Petitioner Dorothy McNeill resides one mile south of the proposed bridge on a canal leading to the Estero River, which she uses frequently. She is the president and treasurer of Petitioner Estero Conservancy, whose mission is to preserve the Estero River in its natural state. Petitioner Ellen W. Peterson resides on Corkscrew Road, 300-400 feet from the proposed footbridge. For 26 years, she has paddled the river several times weekly, usually upstream because it is prettier. She formerly canoed, but now kayaks. The record is devoid of evidence of the water- quality criteria for the Estero River at the time of its designation as an OFW or 1995, which is the year prior to the subject application. Koreshan has not provided reasonable assurance that the proposed footbridge would not adversely affect the water quality of the Estero River. Although the site of the proposed footbridge is devoid of bottom vegetation and there is no suggestion that this is anything but a natural condition for this part of the riverbottom, there is evidence that the proposed footbridge would adversely affect the water quality in two respects: turbidity caused by the pilings and leaching from the chromated copper arsenate applied to the pilings. The turbidity is probably the greater threat to water quality because it would be a permanent factor commencing with the completion of the installation of the pilings. The leaching of the heavy metals forming the toxic preservative impregnated into the pilings is probable due to two factors: damage to the PVC liner from collisions with inexperienced boaters and high-water conditions that exceed 1 foot over mean high water and, thus, the top of the liner. Both of these factors are exacerbated by flooding, which is addressed below. Koreshan also has failed to provide reasonable assurance that the proposed footbridge is clearly in the public interest under the seven criteria. The proposed footbridge would adversely affect the public health, safety, or welfare and the property of others through exacerbated flooding. South Lee County experienced serious flooding in 1995. In response, Lee County and the South Florida Water Management District have attempted to improve the capacity of natural flowways, in part by clearing rivers of snags and other impediments to flow, including, in the case of the Imperial River, a bridge. One important experience learned from the 1995 floods was to eliminate, where possible, structures in the river, such as snags and pilings, that collect debris in floodwaters and thereby decrease the drainage capacity of the waterway when drainage capacity is most needed. Longer term, the South Florida Water Management District is considering means by which to redirect stormwater from the Imperial River drainage to the Estero River drainage. The addition of five pilings (more as the river rose) would exacerbate flooding. On this basis alone, Koreshan has failed to provide reasonable assurance. Additionally, though, the HEC II model output offered by Koreshan does not consider flooding based on out-of-banks flows, but only on the basis of roadway flows. In other words, any assurances as to flooding in the design storm are assurances only that U.S. Route 41 will not be flooded, not that the lower surrounding land will not be flooded. Koreshan failed to provide reasonable assurance that the proposed activity would not adversely affect the conservation of fish and wildlife, for the reasons already stated with respect to water quality. Koreshan failed to provide reasonable assurance that the proposed activity would not adversely affect navigation or the flow of water. The flow of water is addressed above. Navigation is best addressed together with the next criterion: whether the proposed activity would adversely affect fishing or recreational values or marine productivity in the vicinity of the activity. Despite the presence of only two public launch sites, boating is popular on the Estero River. Reflective of the population growth of Collier County to the south and the area of Lee County to the north, the number of boaters on the Estero River has grown steadily over the years. The canoe- rental business located on the 8.5-acre parcel rented canoes or kayaks to over 10,000 persons in 1996. Many other persons launched their canoes or kayaks for free from this site and the nearby state park. Lee County businesses derive $800,000,000 annually from tourism with ecotourism a growing component of this industry. The Estero River is an important feature of this industry, and the aquatic preserve at the mouth of the river and the state park just downstream from the proposed footbridge provide substantial protection to the scenic and environmental values that drive recreational interest in the river. It is unnecessary to consider the aesthetic effect of a footbridge spanning one of the more attractive segments of the Estero River. The proposed footbridge and its five pilings effectively divide the river into six segments of no more than 14 feet each. This fact alone diminishes the recreational value of the river for the many canoeists and kayakers who cannot reliably navigate the U.S. Route 41 bridge pilings, which are more than twice as far apart. As to the remaining criteria, the proposed footbridge would be permanent and the condition and relative value of functions being performed by areas affected by the proposed activity is high. There is conflicting evidence as to whether the proposed footbridge would adversely affect the remnants of an historic dock, but it is unnecessary to resolve this conflict. The mitigation proposed by Koreshan does not address the deficiencies inherent in the proposed activity.
Recommendation It is RECOMMENDED that the Department of Environmental Protection enter a final order dismissing the petition of Petitioner Council of Civic Associations, Inc., and denying the application of Respondent Koreshan Unity Foundation, Inc., for an environmental resource permit and authorization to obtain an easement for the use of sovereign land.

The Issue Whether Southern Hy Power Corporation (Hy Power) has provided reasonable assurance, based on plans, test results, or other information, that its proposed hydroelectric facility will comply with the Management and Storage of Surface Water (MSSW) statutes and rules of Southwest Florida Water Management District (SWFWMD) and the Wetland Resource Management permit (WRM)/water quality certification statutes and rules of the Florida Department of Environmental Protection (DEP).
Findings Of Fact By Joint Prehearing Stipulation the parties agreed to the following description of the parties and the project: PARTIES: The Department of Environmental Protection (the Department) is a government agency in the State of Florida existing by virtue of Section 20.255, Florida Statutes, and operating pursuant to Chapters 253, 373, 376, and 403, Florida Statutes, and Title 62, Florida Administrative Code. Under an interagency agreement with SWFWMD, the Department also implements Title 40D, Florida Administrative Code. The Department is located in Tallahassee, Florida, and it has a district office in Tampa, Florida, which district includes Levy County. Southern Hy Power Corporation is a Florida Corporation whose principal offices are located at 7008 Southwest 30th Way in Gainesville, Florida. Betty Berger is an interested party with a mailing address of Post Office Box 83, Inglis, Florida. The Campbells are an interested party with a mailing address of 245 Palm Street, Inglis, Florida. Hy Power applied on August 31, 1993, to the Department for a WRM permit/water quality certification to construct a hydroelectric facility on the Inglis By-Pass Channel. The project is located in Section 12, Township 17 South, Range 16 East, within the town of Inglis in Levy County. The facility consists of a powerhouse located on the south side of the channel measuring about 28 feet wide by 115 feet long, drawing water from the Inglis By-Pass Channel, passing it through a single-pit type turbine and discharging downstream of the Inglis By-Pass Spillway Dam. Hy Power applied on August 4, 1998, to the Department for a MSSW permit for the same proposed hydroelectric facility on the Inglis By-Pass Channel. DESCRIPTION OF PROPOSED PROJECT The project involves the construction of an intake structure, powerhouse, and tailrace on a 0.61-acre area located on the south side of the existing Inglis By-Pass Spillway. The facility will take advantage of the existing hydrostatic head that exists on either side of the Spillway Dam, to generate electricity. The powerhouse will be constructed below grade and will contain a single megawatt turbine and generating unit. The intake structure will divert flows from the upstream side of the Spillway Dam through the powerhouse and back into the By-Pass Channel. A small one-story control building and low profile substation will be constructed above grade within the boundaries of the project area. The hydroelectric project is considered to be a "Run of the River" type of facility because it can only use that water which flows down the existing channel. The geometry of the channel restricts flow to a certain amount, therefore the project cannot create or use flows above those that the By-Pass Channel can provide. The overall authority for control of water levels in Lake Rousseau and flow to the lower Withlacoochee River will remain with the DEP. Lake Rousseau was created in 1909 when the Inglis Dam was constructed across the Withlachoochee River for the purposes of hydroelectric generation. The dam impounds over 11 miles of the Withlachoochee River and forms a lake approximately 3,000 to 4,000 acres in size. Prior to construction of the Barge Canal, water released from the Inglis Dam would flow down the lower portion of the Withlachoochee River about 10 miles before entering into the Gulf of Mexico. In the mid to late 1960's the Army Corps of Engineers (ACOE) built a portion of the Cross Florida Barge Canal between the Gulf of Mexico and Lake Rousseau. The canal severed the Withlachoochee River downstream of the Inglis Dam causing its flow to be diverted into the Barge Canal and then into the Gulf. In order to maintain the flow of freshwater from Lake Rousseau to the lower segment of the River, the 8,900-foot long Inglis By- Pass Channel and Spillway were constructed. The resulting downstream flow ensures navigation in the lower portion of the River and sustains its freshwater and estuarine environment. The water level in Lake Rousseau is generally maintained at an elevation of 27.5 feet above mean sea level (msl) by a combination of the Inglis Dam, the Inglis Lock, which is located in the Barge Canal, and the By-Pass Channel Spillway. These water control features are known collectively as the Inglis Project Works. The water levels in the lower Withlachoochee River immediately to the west of the By-Pass spillway are close to sea level. The resulting head provides the potential energy needed to drive the proposed generator turbine. Under normal conditions the majority of water released from Lake Rousseau flows over the Spillway Dam into the lower segment of the River. According to the DEP Office of Greenways and Trails (OGT), the maximum capacity of the existing By-Pass Channel Spillway is 1,540 cubic feet per second. The hydroelectric project will divert whatever flow is allowed around the existing spillway through the turbine and back into the channel. When the Cross Florida Barge Canal project was cancelled in the 1990's, the ACOE transferred ownership of the property to the State of Florida Board of Trustees, who in turn has leased the property to the DEP for use as the Cross Florida Greenbelt State Recreation and Conservation Area. Management of this property, the control of river flow and lake levels, and operation of the Inglis Project Works are exercised by the DEP's OGT. The OGT utilizes a document entitled "Water Control Plan for Inglis Project Works," dated September 1994, as a guide to operating the structures. The Water Control Plan is incorporated as part of the MSSW intent to issue. On or about April 25, 1995, the Governor and Cabinet, sitting as the Board of Trustees of the Internal Improvement Trust Fund ("Trustees"), approved a request from Hy Power to sublease 0.61 acres of Greenway property at the project site for the purpose of providing electric power. The request was challenged by Berger and the Campbells, and resulted in an administrative hearing held on November 3, 1995. As a result of the hearing, Administrative Law Judge Larry Sartin entered a Recommended Order on July 12, 1996, that the Board enter an order approving execution by the DEP of the proposed sublease and dismissing the petition of Berger and the Campbells. The Recommended Order was approved by the Trustees in its entirety in a Final Order dated April 12, 1996 ("Final Order"). Berger v. Southern Hy Power Corporation et al., Case No. 95-3589. A copy of the Final Order is listed as an exhibit to this Stipulation, and the Findings of Fact and Conclusions of Law contained therein are adopted herein. As previously ruled by the undersigned, the previous Final Order is res judicata as to Petitioners in this case, who are collaterally estopped from challenging any of the findings of fact or conclusions of law contained in the previous Final Order. Petitioners reserve the right to litigate issues of fact and law not addressed in the Findings of Fact or Conclusions of Law contained in that Final Order with regard to the permittability of this project under the WRM and MSSW permitting proposals, and to raise objections as to relevance to this proceedings of any of the Findings of Fact or Conclusions of Law in the Final Order. On February 21, 1995, Hy Power filed application with the Federal Energy Regulatory Commission (FERC) for a conduit exemption from the licensing requirements of Part I of the Federal Powers Act (FPA) for the proposed project. Petitioners and various other persons filed protests with FERC in opposition to the project. On April 21, 1997, FERC issued an Order Granting Conduit Exemption, a copy of which is listed as an exhibit to this Stipulation. Petitioners in this case are collaterally estopped from challenging any of the findings or conclusions contained in that Order Granting Conduit Exemption. Petitioners reserve the right to litigate issues of fact and law not addressed in the Findings of Fact or Conclusions of Law contained in that Order Granting Conduit Exemption with regard to the permittability of this project under the WRM and MSSW permitting proposals, and to raise objections as to relevance to this proceedings of any of the findings or conclusions in the Order Granting Conduit Exemption. FACTS ADDUCED AT HEARING OUTLINE OF PROJECT The proposed project calls for the construction of a water retention structure along the existing By-Pass spillway, the excavation of a large hole in which the powerhouse and turbine would be constructed "in-the-dry" south of the existing dam, and a millrace below the proposed project to return the water back into the existing water course. Conflicting testimony was received regarding the facts surrounding the construction of the project. These included: whether the proposed project will touch the existing wing walls of the existing dam; whether the water retention structure is a coffer dam; whether the proposed water retention structure will safely retain the water; whether the powerhouse and turbine have sufficient negative buoyancy to stay in the ground; whether the proposed excavation will weaken the existing dam; and whether the de-watering of the excavation site will adversely impact ground and surface water. PROJECT DESIGN AND ENGINEERING Engineering for the project was directed by witness Richard A. Volkin, a professional engineer and president and CEO of Engineering Company, Inc., based in Canton, Massachusetts. Mr. Volkin has extensive national and international experience in the design, management, and operation of hydroelectric facilities. Other engineers in Mr. Volkin’s firm worked on the project under Mr. Volkin’s direct supervision, including John May, who became registered as a professional engineer in Florida in order to sign and seal the engineering drawings for the project, which he initially did around 1994. Mr. May became ill and retired in 1998. Because of the length of time the application process has taken and the fact that Mr. May retired, there was a time while the application was pending, when Hy Power's design team was without a registered Florida engineer. When this was brought to the attention of Hy Power, Hy Power substituted Steven Crockett for Mr. May as the Florida-registered professional engineer of record for the project. DEP routinely accepts an applicant’s changing its engineer of record during the course of permit application or construction. Mr. Crockett is a civil and structural engineer who has considerable experience in preparing dam structural designs. Mr. Crockett independently reviewed and evaluated the engineering drawings for the project. Mr. Crockett resealed the drawings by using his drawn seal and signing the plans because his embossed seal was not readily available and time was of the essence. Mr. Crockett has advised DEP that he is now engineer of record for the project, using the appropriate DEP forms. Mr. Volkin’s firm performed all of the studies required by the various agencies, including a geotechnical study of the area, a 50-year analysis of water flow in and out of the Lake Rousseau regime, and water quality evaluations of water in the By-Pass Channel. The ACOE performed deep hole borings of the soils (approximately 36-40 feet below sea level) in the area of the project site to determine soil stabilization conditions at the site when they were constructing the Inglis Project Works. The soil conditions found can reasonably be expected to be similar today. Mr. Volkin’s company also took its own eight-foot deep surface core samples. The purpose of those samples was to verify the ACOE data. The new core samples verified the original core samples. Mr. Volkin also reviewed the ACOE’s engineering drawings developed from construction of the Spillway Dam. These show that the dam is founded on limestone bedding that has been stabilized with concrete. The hydroelectric facility will be constructed adjacent to and south of the dam structure and adjacent to and north of the barge canal. The same type of limestone bedrock is found in the area of the proposed construction. The facility design includes an intake channel on the upstream channel and a tailrace downstream. Those are the only structures that will be constructed next to the By-Pass Channel. The construction of the facility itself will be "in the dry." Hy Power will use coffer dams to seal off the construction site from the By-Pass Channel, so that there will not be water leakage from the Channel into the construction site. Water from the By-Pass Channel will enter the power plant when the coffer dams are lifted and the water is allowed to flow into the facility. The Petitioners presented the testimony of Bill Edwards, an individual with considerable experience in the construction of bridges, cofferdams, and similar concrete structures in aquatic and semi-aquatic conditions. Mr. Edwards is a former hard-hat diver who worked all over the world and worked in Florida for many years prior to his retirement. Based upon his experience and expertise in construction related to projects of this type, his testimony is credible and worthy of consideration. Mr. Edwards pointed out that if the proposed water retention structure did not touch the wing wall of the existing dam, it could not keep the water out and would not have the strength that it needed to retain the water. Hy Power’s witnesses explained that the retention structure would be set close enough to the existing wing wall that waterproofing materials could be placed between the two structures to keep the water out. Further, that the existing plans did not show interior bracing which would be included for structural strength and integrity. In sum, the retention structure will be in contact with existing dam’s wing wall, but will be free standing and not dependent upon the strength of the wing wall for its strength. Mr. Edwards pointed out that a cofferdam by definition has walls on all sides of the structure. The structure proposed by Hy Power did not have walls all the way around the proposed excavation. In rebuttal, Hy Power presented evidence that its plans were conceptual, design drawing and not construction plans. Hy Power represented that in actuality it would put as many walls as were necessary to keep the water out of the hole it intended to excavate. Trash racks will be constructed at the intake structures to protect aquatic life and make sure that trash and vegetation do not enter the intake structure or go down river. The trash rack bars will be two inches on center, which the U.S. Fish and Wildlife Service has determined as the appropriate size for the protection of fish. The turbine blades are "double regulated," and operate generally between 60 and 90 revolutions per minute. The design enables the turbine to operate at a constant speed to generate a consistent flow of electricity, notwithstanding the fact that the flow of the water may vary. The blade speed is not very fast, and the 2.5-meter blades provide a two to three-foot opening. This design acts to prevent fish mortality. There are four ways to shut off the flow of water through the proposed structure: close the pitch of the blades, close the wicket gates, allow the counter balance to the wicket gates to kick in and automatically close the gates, and close off the main gates. This is a fail safe system ("four level redundancy") designed to work upon any failure. Once water goes through the generator, its velocity is reduced to no greater than its intake rate which is a maximum of three feet per second. This prevents the water being discharged from the tailrace from causing erosion. If the head of water in the dam produces a flow exceeding three feet per second, it can be diverted over the other dams which will be functional. The power plant will be encased in concrete, except for a small access way that enables a person to go down a set of stairs to the plant. It will be a sealed, waterproof structure, as required by FERC and the ACOE. This will prevent penetration of groundwater, or flood waters in the event a massive flood overtops the plant. The only water entering the powerhouse will be through the turbine tunnel for power generation purposes. Mr. Edwards pointed out that the powerhouse was a closed structure and as such would have positive buoyancy, that is, it would float. Mr. Edwards pointed out that the proposed site is between the barge canal and By-Pass spillway and there is a great deal of groundwater and potentiometric pressure in the existing water table. In sum, there is a unlimited supply of groundwater at the site, and powerhouse could float out of the ground just like an empty swimming pool. Hy Power presented rebuttal evidence that the weight of the building, the turbine, and the water flowing through the turbine would be close to negative buoyancy, and they would add additional weight to the structure as necessary to keep it in place. The project is designed to generate three megawatts of electric power which is enough electricity to serve between 300 and 3000 homes, depending on usage. The project is designed to be unmanned. This is common for facilities such as this. The plant can be operated by remote control, unlike the existing controls at the By-Pass Dam, which are operated manually. DEP can access, monitor, and control remotely the generator's operation to include shutting the facility down at any time. There will be remote sensors to monitor water elevations. Flood protection will improve because of the ability of DEP to manage water flow from a remote location. If there is any major disruption, the plant will shut itself down. The project is classified as "green power." In other words, it generates natural energy without any disruption to the environment. The project will have minimal to no impact on the environment. There will be no significant changes in water quality compared to existing conditions as a result of either construction or operation of the facility. WRM Permit Criteria Hy Power has provided reasonable assurances that the proposed project will not cause a violation of state water quality standards of Section 403.918(a), Florida Statutes (1991). The parties stipulated that turbidity and dissolved oxygen were the two surface water quality issues of concern in this proceeding. The receiving water body is the Inglis By-Pass Channel. The Inglis By-Pass Channel is a Class III surface water. The project is not located in a OFW. While the lower Withlacoochee River is an OFW, the OFW designation runs up the natural river itself, and does not include the Spillway Dam, tailrace, or the remainder of the By-Pass Channel. There would be no degradation of water quality at the point of contact with the Withlacoochee River OFW. The DEP and FERC looked specifically at potential for turbidity and dissolved oxygen in determining whether the project would violate state water quality standards. The standards for turbidity and dissolved oxygen will not be violated. Because the By-Pass Dam is an under flow structure, a minimum of oxygenation currently occurs as water flows through the existing dam. The proposed project runs the water underground through the generator; however, Hy Power will measure the dissolved oxygen below the dam in the Lower Withlacoochee River. In the event there is any lowering of dissolved oxygen, Hy Power can install a "sparge ring" to reoxygenate the water going through the turbine so that dissolved oxygen remains at current levels. No turbidity will be added to the receiving water as a result of the project, because water velocity is low and the structure is encased in concrete and rip-rap. The only other potential for turbidity would occur when the coffer dams are removed after construction is complete. The coffer dams can be removed with the generator closed to permit any turbidity to settle. The amount of siltation that might occur when the generator is opened would be insignificant. Where a project is not in a OFW, an applicant must provide reasonable assurance that the project will not be contrary to public interest. See Section 403.918(2), Florida Statutes (1991). Hy Power has provided such assurances. The project will not directly affect public health, safety or welfare, or the property of others. See Section 403.918 (2)(a)1., Florida Statutes. There are concerns relating to the structural integrity of the proposed facility and adjacent structures which are discussed extensively below. The project will have no adverse impact upon the conservation of fish and wildlife, including threatened and endangered species and their habitat. See Section 403.918 (2)(a)2., Florida Statutes. While manatees are not likely to be found at the project site, the installation of the trash racks will eliminate any potential adverse impact on manatees. In fact, the racks will be an improvement over the current unprotected Spillway Dam. DEP procedures require a specific manatee control plan be implemented to deal with site specific concerns. The project will not adversely affect navigation or the flow of the water or cause harmful erosion or shoaling. See Section 403.918(2)(a)3., Florida Statutes. The project will not adversely affect fishing or recreation values or marine productivity in the vicinity of the project. See Section 403.918(2)(a)4., Florida Statutes. The permanent project and its construction will cause no significant environmental impacts. See Section 403.918(2)(a)5., Florida Statutes. There will be no adverse impacts to significant historical and archeological resources. Section 403.918(2)(a)6., Florida Statutes. With regard to the impact on current conditions and relative value of functions being performed by the areas affected by the proposed activity, there will be no negative impacts. See Section 403.918(2)(a)7., Florida Statutes. Improvement will result from better control of water flow at the project site, installation of trash racks and implementation of green power. THE FORESEEABLE ADVERSE SECONDARY OR CUMULATIVE IMPACTS Potential adverse secondary impacts related to power transmission are addressed through the fact that there is an existing power line corridor that can be used to transmit the electricity. Any need to change the corridor could be addressed by subsequent DEP permitting. Cumulative impacts are not at issue. Mr. Gammon, with Florida Power, acknowledged that the current electric company, presumably Florida Power, would be required by FERC to transport the electricity generated by Hy Power over its existing corridor and poles. No final decision has been made regarding how to access the site with equipment during construction. Several feasible construction options exist, and there are several ways of accessing the site with heavy equipment vehicles and without impacting wetlands. Any final decision would be subject to DEP approval. Since the project meets the public interest criteria of Section 403.918(2)(a), Florida Statutes, and wetland impacts are minimal, the project is permittable without the need for mitigation. See Section 403.918(2)(b), Florida Statutes. The ACOE has issued a permit for the facility. The permit varies slightly from the DEP intent to issue in the use of reinforced concrete rather than rip-rap on the bottom half of the intake channel. This is to comply with ACOE preference, but the variation has only an environmental benefit. Counsel for Petitioners sought to elicit testimony from Linda Sloan, Executive Director of the Withlacoochee Regional Planning Council, with regard to compliance of the proposed project with the Town of Inglis Comprehensive Plan and Land Development Code. Such compliance is not relevant to this proceeding. At any rate, Ms. Sloan conceded that any prohibition that might apply in the Land Development Code to construction of the proposed facility could potentially be alleviated by exemption or variance provisions in the Code. MSSW PERMIT CRITERIA The project will provide adequate flood protection and drainage in the conventional sense. See Rule 40D-4.301(1)(a), Florida Administrative Code. Because the amount of impervious area is minimal, runoff from the project will not in any way contribute to increased flooding or adversely impact drainage patterns. The total amount of impervious area of the facility is less than that of a single-family residence. SWFWMD rules do not even require MSSW permits for single-family residences because the impact is not significant. The only purpose for requiring a MSSW permit for the project is to review the project’s potential downstream impacts to the watershed, not stormwater runoff from the facility itself. The project will not cause adverse water quality or water quantity impacts on adjacent lands in violation of Chapter 373, Florida Statutes, or cause a discharge that violates state water quality standards. See Rule 40 D-4.301(1)(b), Florida Administrative Code. As indicated by the WRM water quality findings above, the project will not generally violate state surface water quality standards. See Rule 40 D-4.301(1)( c), Florida Administrative Code. The project will not generally cause adverse impact on surface or groundwater levels or flows. See Rule 40 D- 4.301(1)(d), Florida Administrative Code. Since the project is a run-of-the-river, it will not diminish the capability of a lake or other impoundment to fluctuate through the full range established for it under Chapter 40D-8, Florida Administrative Code. The project will not cause adverse environmental impacts, or adverse impacts to wetlands, fish, and wildlife or other natural resources. The project can be effectively operated and maintained. See Rule 40D-4.301(1)(g), Florida Administrative Code. The project is a slow speed, low maintenance facility. The design concept is well established and has been successfully used for many years. Possible adverse affects to public safety are discussed below. The project is consistent with the requirements of other public agencies. See Rule 40D-4.301(1)(i), Florida Administrative Code. Potential harm to water resources within the SWFWMD are discussed below. See Rule 40D-4.301(1)(j), Florida Administrative Code. The proposed project generally will not interfere with the legal rights of others. See Rule 40D-4.301(1)(k), Florida Administrative Code. The proposed project is not against public policy. See Rule 40D-4.301(1)(l), Florida Administrative Code. The project complies with the requirements contained in the Basis of Review. See Rule 40D-4.301(2), Florida Administrative Code. There is a dispute as to whether the project was within or at the edge of the 100-year flood plain. This dispute is related to how one interprets the rule as it relates to the millrace and the location of the facility which is under ground. In the conventional sense, the project is not in the flood plain. Further, the project is designed in such a way, that it is waterproof if it were topped with water. While in the past SWFWMD may have had concerns that the project might cause downstream flooding, SWFWMD currently has no such concerns, given the run-of-the-river status of the proposed project. The operation of the project will not cause downstream flooding. The DEP included in its intent to issue, conditions contained in the sublease between Hy Power and the DEP in order to ensure that the facility would remain run-of-the-river, would comply with the water control plan, and would otherwise comply with the terms of the sublease. The DEP has final control over water flow and can revoke the permit or otherwise take enforcement action against Hy Power if Hy Power fails to comply with the water control plan. GROUNDWATER IMPACTS Operation of the project will not cause groundwater contamination or otherwise have adverse groundwater impacts. Some concerns about groundwater during excavation of the construction site were raised. The conflicting evidence received regarding them is discussed below. An area of concern was the de-watering plan for the project. Everyone agrees there will be some water seepage into the construction site that will have to be pumped out. The parties disagree regarding the amount of water that will have to be removed. Their estimates of amount of water to be removed vary because their estimates of size and over-all depth of the site vary. Petitioners presented credible evidence that a potential exists for the construction site to have a large quantity of water because of its location between two sources of surface water (the By-Pass Channel and Barge Canal), because of the makeup of the subsurface, and because of the depth of the construction. Hy Power credibly represents that if excessive groundwater is found, it can address the adverse impacts through its de-watering plan that would have to be filed with FERC and DEP. The technology exists to address the de-watering of the project. Such plans are routinely considered by DEP after a construction permit is issued and before de-watering occurs. There is very little evidence of sinkhole activity in the project area, and the construction activities are not expected to cause any sinkhole activity. NOISE POLLUTION Mr. Bitter expressed concerns that FERC would require the facility to install a very loud siren that would result in sudden noise adverse to the well-being of neighbors. Mr. Bitter is unfamiliar with FERC siren requirements at run-of the-river hydroelectric facilities. In contrast, Mr. Volkin, who has substantial experience in this area, testified that the only alarm device that would be required would be for the protection of the workers during construction. The purpose of the alarm is to warn persons below a dam spillway of a change in the volume of water being let out of the impoundment. In the case of a run-of-the-river facility, the volume is near constant, changing only gradually. Therefore, even if a warning siren had to be installed its use would be limited to significant changes in flow or testing. This would not constitute a nuisance. Further, the facility is located in the vicinity of the Crystal River Nuclear Power Plant which has its own warning sirens. It would be prudent to make any warning devices required for this structure significantly different from those at the nuclear plant and to limit their use. DAM SAFETY AND FERC REVIEW In reviewing whether Hy Power’s applications complied with the relevant permitting criteria, the DEP took into consideration the review of the facility already performed by FERC. FERC will also be responsible for reviewing the project as it is being constructed. Mr. Edwards also raised concerns about the structural stability of the By-Pass Dam itself. This has been a subject of concern by those responsible for the dam, and a survey of the structure was conducted in 1993, referred to as the Greiner Report. The Greiner Report identified specific maintenance problems that have been and are being addressed by the DEP. However, DEP’s maintenance plan does not address specifically the possibility that the weight of the dam over time has caused some shifting in the dam. Hy Power has only a few core borings and only one at the location of the generator. Hy Power is using the ACOE’s original borings, as confirmed by several new ones, to develop its preliminary plans. The DEP considered FERC and the ACOE as responsible agencies for determining the structural integrity of the dam. DEP has taken FERC’s review of this facility into consideration as part of DEP’s own permitting review. It is normal for DEP to rely on outside sources and agencies for assistance in determining compliance with DEP permitting criteria such as public health and safety, and it is reasonable for DEP to do so in this instance. Most states do not have the full capability to evaluate dam safety, and so they rely on FERC and ACOE. On April 21, 1997, the project received a conduit exemption from FERC. The application process is illustrated in Hy Power Exhibit 11. Hy Power submitted to DEP detailed information about the dam, the associated structures and the proposed project which had been reviewed by FERC and the ACOE, the two agencies in the United States who are responsible for dam structure design, control, and administration. Included in the package was the Greiner Report and Hy Power’s review of it. FERC evaluated the project, the Inglis By-Pass Dam structure, and the proximity of the project to the Dam in relation to structural impact, upstream and downstream impacts, water quality, and environmental issues. Mr. Edwards raised concerns regarding the ability of the limestone bedrock to sustain additional construction in the area of proposed construction. This is a material issue in the controversy which impacts several aspects of the proposed construction. Mr. Edwards pointed out that the barge canal channel was constructed with the use of explosives that caused a fracturing of limestone bedrock. He pointed out that the steel panels, which Hy Power proposes to drive into the bedrock to construct the water retention structure necessary to excavate the hole into which the turbine and powerhouse would be placed, will further fracture this bedrock. This creates two potential dangers. It could permit water to move under and around the bottoms of the panels, potentially scouring the loosened material from the base of the panels and making them unstable and subject to failure. It could weaken the entire southern wing of the existing spillway dam. Mr. Edwards opined that this could result in catastrophic failure of the dam or the coffer dam. Such a failure would cause major destruction and loss of life to those persons living and working in and along the lower Withlacoochee River. Hy Power presented rebuttal evidence that it could and would, if necessary, inject concrete into the limestone to stabilize it and avoid the concerns raised by Mr. Edwards. FERC specifically evaluated concerns raised by project opponents over the poor physical condition of the By-Pass Channel Spillway structures, relying particularly on the 1993 Greiner Report. FERC noted that the DEP had entered into a contract to correct any deficiencies listed in the Greiner Report, which "did not conclude that the deficiencies at the By-Pass Spillway threaten downstream life and property." The FERC review concluded that the dam was safe. To ensure safety, FERC is requiring that Hy Power do a complete stability analysis of the dam prior to any construction. Articles 301 and 302 of the FERC exemption ensure that all final drawings and specifications be submitted to FERC prior to construction, along with a supporting design report consistent with FERC’s Engineering Guidelines; that FERC can require changes to assure a safe and adequate project; and that Hy Power must also submit approved coffer dam construction drawings and specifications at least 30 days prior to starting construction. FERC has its own engineering staff who will go to the site and do their own analysis, along with the ACOE, of the dam and structures, prior to any construction commencing. This is a detailed design review evaluation so that the latest information on the dam will be made known immediately prior to construction, and will prevent any catastrophic event from happening. Under FERC procedures, FERC requires the applicant to obtain the DEP permits prior to requiring applicant to submit more detailed construction designs for FERC's consideration. These more detailed designs in turn will be subject to further review by DEP and FERC. It is assumed that Hy Power will comply with the post- permitting procedures and requirements, and will present complete, detailed construction drawings for FREC and DEP approval. Hy Power’s failure to complete the process would result in denial of a construction permit.

Findings Of Fact Petitioner owns a parcel of land including 24 lots that front on an L- shaped canal 1,520 feet long that is landlocked at both ends. At the top, the L-shaped canal is 40 feet across. It has almost perpendicular sides and is eight to ten feet deep. Petitioner proposes to dredge with a steel-track dragline in order to connect the landlocked canal to a canal system that is connected to Kings Bay in Citrus County. Culverts would be placed at the north end of the canal, and earth at the other end would be permanently removed, extending the canal. One result of such dredging would be that two additional lots would abut the L-shaped canal. Even before he bought the property, petitioner discussed some of the problems this project might entail with Alan Burdett, a DER employee. In order to minimize turbidity in open waters, petitioner proposes to dredge outward from the L-shaped canal. Only after the sand from the initial dredging had settled would the final increment of earth be excavated and then only on an incoming tide. Part of the fill would be placed on the bottom of the L-shaped canal to decrease its depth to roughly five feet, more nearly approximating the depth of the canal system to which it would be connected. The water in the L-shaped canal has a high biochemical oxygen demand. The surface is covered with mats of water hyacinths. Floating vegetation intercepts sunlight and interferes with photosynthesis in plants underneath, decreasing their oxygen output. Levels of dissolved oxygen in the water fall as a result. At night, moreover, floating plants may use dissolved oxygen from the water. Dissolved oxygen levels vary diurnally and decrease with depth where water strata are undisturbed. In general, dissolved oxygen levels vary inversely with water temperature. On June 11, 1980, a water sample taken from the bottom of the L-shaped canal was found to be devoid of dissolved oxygen, while a sample from the surface contained 0.4 milligrams per liter of dissolved oxygen. One of petitioner's witnesses described the water in the L-shaped canal as very foul. On the morning of August 21, 980, a dissolved oxygen level in the L-shaped canal of two milligrams per liter was measured. DER's Exhibit No. 2. Sampling of water in the L-shaped canal by petitioner's agent on October 4 and 5, 1979, indicated dissolved oxygen levels of 4.1 milligrams per liter at high tide and 0.5 milligrams per liter at low tide. Petitioner's Exhibit No. 5, Table 3. A witness who reported seeing fish in the L-shaped canal testified that introducing water from the L-shaped canal into the existing canal system could cause a localized fish kill. This danger is evidently not very great, but the evidence did establish that the high level of biochemical oxygen demand and low level of dissolved oxygen found in the L-shaped canal are harmful rather than helpful to fish. The canal system which would receive the water now contained in the L- shaped canal, opens into Kings Bay, the spring-fed source of Crystal River, which one of the petitioner's witnesses characterized as a "complex and sensitive estuarine system." Kings Bay, Crystal River, and the canals into which petitioner proposes to open the L-shaped canal constitute Class III waters. Water in this vicinity is high in chlorides but is classified as fresh water. In the canal system to which petitioner proposes to add the L-shaped canal, rafts of water hyacinths are present. Water quality in the canal system is poor, according to petitioner's expert witness. Measured level of dissolved oxygen in this canal system ranged from 9.0 milligrams per liter in early October of 1979, Petitioner's Exhibit No. 5, Table 3, to 1.9 milligrams per liter on June 11, 1980. Petitioner's Exhibit No. 6. It takes some four days to flush the existing canal system. The time necessary for flushing the canal system would increase if it is enlarged as proposed by petitioner, even though flushing action in one part of the present canal system would be facilitated. Crystal River is subject to tidal influence. Notwithstanding the 600 million gallons of water entering Kings Bay daily from springs, the incoming tide causes a current upriver. As a result, as much as five percent of a substance flushed out of a canal system like the one petitioner proposes to enlarge can be reintroduced into the canal system when the tidal flow reverses. The fecal coliform count in a sample of water taken from the L-shaped canal was very low, 10 per 100 milliliters. A water sample taken nearby downstream, in the vicinity of residential development, contained 850 fecal coliform bacteria, per 100 milliliters. There was no evidence, however, that these bacteria were attributable to human excreta rather than to the excreta of some wild animal. According to petitioner, persons who live in the area hope this project will go forward because they believe that the stagnant water in the L- shaped canal is a breeding place for mosquitoes. No witness reported seeing mosquito larvae in the L-shaped canal, however, and a biologist who had observed the canal was questioned on this point. Testimony was uncontradicted that small fish of a kind that feed on mosquito larvae inhabit the L-shaped canal. The evidence did not establish that mosquitoes breed in the L-shaped canal. Manatees winter in Kings Bay and Crystal River. These vegetarian mammals are members of an endangered species. Of 34 animals in Kings Bay "sampled [in the fall of 1979] . . . [26] . . . had prop scars, and 10 . . . had wounds in a stage of healing that suggested they were less than two months old." Petitioner's Exhibit No. 3. Efforts to protect the manatees include strict speed limits and a recently constructed structure around a favorite spot to act as a barrier for motor boats. A purpose of making the canal connections petitioner proposes is to make Kings Bay and Crystal River more accessible to motor boats.
Recommendation Upon consideration of the foregoing, it is RECOMMENDED: That respondent deny petitioner's application for permit.
