Findings Of Fact The Applicant, John E. Bravo, applied for a dredge and fill permit to construct a dockage facility. The proposed facility will consist of a 910 foot pier with a "T"-shaped platform structure extending perpendicular in two directions from the seaward end of the pier, all of which is designed to accommodate 56 boat slips, restricted to the use of pleasure boats only. The proposed project site is located on the southeast side of "Long Point" and would extend into the waters of East Bay, which is a tidally influenced water body in Bay County, Florida. The project site lies in Class II waters of the State. The waters involved are not approved for shellfish harvesting, however, but rather are under a shellfish harvesting prohibition imposed by the Department of Natural Resources. The portion of East Bay involved also lies within the Intracoastal Waterway. The waterway is approximately 6,000 feet wide at the site of the proposed docking facility. The water along the shoreline of the area is shallow for a considerable distance waterward. The bay bottom is characterized by profuse seagrass for approximately 500 feet waterward of mean high water. Beyond that point, the seagrass (Cuban Shoal Grass) dissipates and disappears. The first 400 feet waterward of the mean high water line at the location of the proposed dock, is shallow and not truly navigable. The water then deepens to approximately five feet at mean low water some 525 feet from the shore. This distance from the shore marks the beginning of the area where no significant amount of seagrass exists and where the boat docking slips and mooring pilings would be installed in a waterward direction down the remaining length of the proposed dock. The water depth continues to increase to approximately 20 feet at the proposed location of the end of the dock. The dock would be constructed of pilings driven into the bay bottom supporting the decking of the walkway portion and "T" portion of the dock. The "T" would be installed on the seaward end of the dock, perpendicular to the walkway portion of the dock with most of the boat slips installed and operated at that point. The length of the docking facility is dictated by the fact that the Applicant seeks to locate the boat slips in a manner so that all boats will be moored and operated well beyond existing seagrasses. In fact, the length of the dock is more than absolutely necessary to accomplish this purpose since water depth and avoidance of seagrasses could accomplished with the dock ending approximately 700 feet from the mean high water line. In an abundance of caution, however, in order to avoid the possibility of propeller dredging and prop wash damaging the bottom substrates and grasses, and since the Intracoastal Waterway is over a mile wide here, the Applicant elected to design the dock in the length and configuration proposed. Such will cause no unreasonable impediment to navigation. In this connection, the Applicant has agreed to post Coast Guard- approved safety lights on the dock which will warn boats of its presence in hours of darkness. Further, the dock does not extend far enough into the 6,000 foot wide Intracoastal Waterway to pose a hazard to barge and other boating traffic in the Waterway. Some of the Petitioner's witnesses revealed that shrimp boats pull their nets during shrimping operations closer than 900 feet to the shore line and in the vicinity of the grass beds. While the presence of the dock may alter the trawling pattern of shrimp boats and the operations of other commercial fishermen, as well as water skiing and boating by members of the public, this may in fact have a beneficial effect by promoting the public interest in preserving marine habitat and the conservation of marine resources by preventing some damage to the grass beds. Such marine grass beds are valuable nursery areas for fishes and other marine animals, the effects upon which must be considered in weighing the various statutory indicia of the public interest which must be satisfied before granting a dredge and fill permit. Further, because the dockage facility at issue would be an isolated one with no significant similar docks in the immediate vicinity, the likelihood that it would pose a navigational hazard to water skiiers, fishermen, shrimpers, and other commercial and recreational interests is rather insignificant. Water Quality The water quality issues posed by a project such as this typically involve the water quality parameters of dissolved oxygen, nutrients, bacteriological quality, turbidity, oils, greases, fuel, paint or varnish, solvents and heavy metals, as contemplated by the below-cited rules concerning general surface water quality criteria and the specific rules related to Class II surface waters. The project site is located in Class II surface waters of the State. Those Class II waters are classified by the Department of Natural Resources as "not approved" for shellfish harvesting. The zone of the Class II waters of East Bay in which shellfish harvesting is not approved extends some two miles eastward of the project site. Marinas and dockage facilities such as this one, which will accommodate fairly large boats in significant numbers, typically pose potential pollution problems involving deposition of nutrients in State waters in the form of fish carcasses and offal, garbage and human wastes. Additionally, boats can pose pollution hazards because of attendant dumping of grease, oil and fuel residues in marina waters as well as the deposition of trash in various forms such as paper and plastic items as a result of human use of the boats and the marina facility itself. Perhaps the most severe potential problem is the deposition of human fecal matter into the water as a result of the flushing of marine heads on the larger boats, which the dockage facility will accommodate in the slips as designed. The fecal coliform bacteria which emanate from the deposition of human wastes into the waters around such a dockage facility can be concentrated in oysters and other shellfish to such an extent as to cause severe illness, permanent disability or even death in humans. Consequently, in order to avoid this problem in a magnitude which would violate the water quality parameter in the rule cited below for bacteriological quality, substantial measures must be taken with a project such as this to avoid the deposition of human wastes from the dockage facility itself and from the boats using the slips. In furtherance of this end, the Applicant proposes to allow no live- aboard vessels to be occupied over night while moored at the docking facilities. Live-aboard vessels are deemed to be those with sleeping accommodations and marine heads. The Applicant also proposes to employ a full-time dock master seven days a week, eight hours a day to ensure that all dockage users are familiar with dockage rules, and who would enforce them, especially that prohibiting any discharges from vessels using or docking at the marina. The rules would be incorporated in the dockage lease agreements. The dock master would be responsible for the clean up and correction of all unauthorized discharges. In view of the potential for sewage discharges from marine heads, even with sewage pump-out facilities and the other restrictions on the use of live-aboard type boats, the additional protective measure of requiring a sewage pump-out line and pump-out equipment, including a storage tank and a means to direct sewage pumped from boats into the upland sanitary sewer system, should be imposed as an additional condition. Additionally, the restriction against over night stays aboard boats, the discharge of marine heads into the marina waters and the requirement for use of the sewage pump-out system should be publicized on large, easily legible signs at various points on the pier so that all boat slip renters or users can be on notice of the restrictions and the dock master's and the Department's enforcement of them. Additional potential sources of nutrient and bacteriological degradation of the dissolved oxygen content and bacteriological integrity of the surface waters involved can be posed by the deposition of fish carcasses and parts, as well as food wastes and other garbage in the marina waters. In order to prevent this, the Applicant has proposed to provide fish cleaning stations located on the upland and to require all fish carcasses and other related wastes to be placed in upland containers and not disposed of in the Class II waters at the dock site. Additionally, waste containers will be located along the length and perimeter of the dock facility for garbage, with regular emptying of the containers enforced by the dock master to prevent spillage. In connection with the upland fish cleaning sites to be installed, the drainage waters or waste water from fish cleaning stations should be directed into an upland disposal system so that it may be ensured that the water does not get back into the Class II waters of the bay. In addition to the above measures, pump-out facilities and equipment will be provided by the Applicant for used engine oil removed from boats and oil and water from boat bilges. These wastes, under agreed-upon conditions, would be transported by pipeline to the upland to a storage tank pending proper disposal. Trash, garbage and other refuse will be deposited in dumpsters for removal by municipal garbage disposal services. No fueling facilities or fueling of boats will be allowed. Additionally, oil spill clean up materials will be maintained on the marina site in sufficient quantities to allow clean up of the maximum spill expected from the largest boat typically using the marina pursuant to the leases for the boat slips. In order to further lessen the possibility of spills of oils, greases and fuels, the permit should be conditioned (as should the leases) upon no boat maintenance being performed at the marina site other than minor engine adjustments. In this context, an additional enforcement measure will be in the boat slip rental agreements themselves. The agreements will contain restrictive provisions requiring lessees to properly handle and dispose of fish carcasses and wastes, used engine oil, bilge water and requiring them to comply with sewage pump-out and refuse disposal conditions enumerated above. Upon completion of the facility, the dock master will manage and accomplish maintenance of the various items of equipment, such as the pump-out facility, on an eight hour a day, seven day per week basis and will enforce the restrictive provisions incorporating the above conditions in the boat slip rental agreements. Those restrictive provisions should include putting the lessees on notice that violation of any of the conditions enumerated above and in the boat slip leases will result in a breach of the lease and removal of their vessel from the marina and reporting of the violation to regulatory authorities. The various expert witnesses agreed that the proposed permit conditions enumerated above, if enforced, would adequately protect water quality as to the above parameters at issue. The Class II water quality standards will not be violated by the installation and operation of the project as proposed, provided the above conditions are strictly enforced and adhered to. Mr. Jack Taylor, the expert witness for the Petitioner, agreed that the above measures would reasonably ensure that the marina will not cause pollution and contravention of Class II water quality standards, but feared that enforcement problems would prevent such conditions from prevailing. In view of the measures enumerated above which will be undertaken by the Applicant to ensure that water quality standards are adhered to, including the liberal use of warning signs for marina customers and slip lessees, the use of a full-time dock master to enforce the conditions and including the enforcement measure of putting the conditions as restrictions in the slip rental leases, it has been shown that the enforcement will be reasonably adequate. An additional and important enforcement measure can be incorporated into this project, however, by requiring the Applicant to submit an operation and maintenance plan for the marina and requiring a monitoring program under the auspices of the Department for at least a year of operation in order to ensure that the project operates as it is proposed under the above-delineated conditions. The Department has continuing enforcement power and the monitoring program would, with regular monthly inspections, allow early detection and correction of any water quality violations, to and including the voiding of the permit and the closing of the marina operation should violations prove severe and uncorrectable. 1/ Such a monitoring program and marina operation and maintenance plan should be required as a condition to granting of the permit. 2/ Finally, it should be pointed out that the area of East Bay where the project would be built is Class II shellfish prohibited waters. The proposed project itself will not likely adversely affect shell fishing to the extent of closing additional waters if the above water quality safeguards are imposed as conditions on the permit and on the marina operation. This is especially true because the boundary line of the shellfish approved water to the east is at least two miles away, which distance incorporates a substantial mixing zone in the open waters of East Bay to sufficiently dilute pollutants which might emanate from the marina or other sources to levels such that the shellfish waters presently open will not be subject to any further closures by the Department of Natural Resources, as a result of this installation. The primary reason the shellfish waters in the immediate vicinity of the proposed project are closed to harvesting is the presence of the Military Point Sewage Treatment Plant which discharges its effluent into the waters of East Bay, such that the DNR's dye flow studies reveal that a 5.1 square mile buffer zone around that plant is necessary for closure to shellfish harvesting to ensure that the public health is not adversely affected by consumption of shellfish from the waters in that buffer area. That buffer area includes the proposed marina site. Additional significant pollution sources include fecal coliform bacteria, oils and greases and other contaminants associated with rainfall events and resultant urban runoff from the City of Parker and surrounding areas, including septic tank leachate and petroleum residues. These influences also currently add to the reasons why shellfish harvesting is precluded in the area of the proposed facility. It was not demonstrated that the addition of the marina and the boats operating under the above strict conditions will result in any additional closures to shellfish harvesting in surrounding, presently approved areas as a result of any water quality degradation posed by the subject project. Public Interest The public interest criteria-enumerated at Section 403.918(2)(a), Florida Statutes, which are actually at issue in this proceeding concern: (1) whether the project will adversely affect the public health, safety, welfare or property of others, (2) whether it will adversely affect conservation of fish and wildlife, including their habitats, (3) whether the project will adversely affect navigation, water flow or cause harmful erosion or shoaling, (4) whether it will adversely affect fishing or recreational values or marine productivity in its vicinity, and (5) whether the current condition and relative value of the functions of the natural area involved at the project site will be adversely affected by the proposed activity. There is no issue or dispute raised concerning the permanence of the project for purposes of criteria number 5 under this subsection, nor as to number 6, concerning historical and archaeological resources. Concerning criteria numbered 1-4 and 7, of this subsection, it has been demonstrated that the project will not likely affect the public health, safety, welfare or the property of others if constructed and operated according to the conditions delineated herein. Some members of the public testifying on behalf of the Petitioner objected to the interference they feared the dock would cause with their jogging along the shoreline and feared an impediment to their use of the area for water skiing. This is the only dock in this vicinity, however, and such interference is minor. It will be well lit in order to avoid impeding navigation or posing a danger to the public health or safety during hours of darkness in terms of the public's ability to safely operate boats in the area. There is some potential for the project adversely affecting conservation of fish and wildlife or their habitats in that, if boats are permitted to operate in the vicinity of the dock and use the dock for mooring, loading and unloading purposes, and the like, closer than 500 feet off shore, harmful propeller washing or dredging of the bottom sediments and seagrasses growing therein will result. If such erosion of the bottom and seagrass growth begins occurring, it will adversely affect and gradually destroy the area as a habitat for fish and other marine life, which is of particular importance since such Cuban Shoal Grass stands are quite beneficial as nursery areas for fish and other organisms. Thus, if boating activity were allowed unimpeded around the dock, including in the near shore area within 500 feet from the mean high water line, the resultant erosion and propeller damage to the seagrass beds in the bottom would indicate that, as to criteria 2 and 3 of the above subsection, that the project would not be in the public interest and would be contrary to the public interest. This same consideration is true with regard to the fourth criteria concerning whether the project adversely affects fishing and recreational values or marine productivity for similar reasons. If marine habitat is disrupted or destroyed in whole or in part in the vicinity of the dock due to erosion and other damage caused by boat and propeller contacts with the bottom or prop wash near the bottom, then as to this criteria, concerning marine productivity and recreational value, the project will be contrary to the public interest also. To the extent that nursery areas for fish and other valuable marine organisms are destroyed, the recreational value in terms of quality of fishing will certainly be diminished. The "current condition and relative value of functions" being performed by the area of marine habitat affected by this project must also be considered. In a like vein, this particular area constituting dense growths of seagrasses has a relatively high functional value as a marine habitat and, particularly, a nursery for marine animals. This current condition and value of the area should be accorded a fairly high status in weighing and balancing the various considerations used in determining whether the project is or is not contrary to the public interest. If the boats which are to use the marina upon its construction and operation are permitted inside the grass bed area, roughly within 500 feet of the shore, then clearly the considerations mentioned above will be the subject of adverse effects caused by the boats' operation which in turn is a direct result of the installation of this marina, the dock and the slips. In view of the reasonable likelihood of the project causing some of the adverse effects mentioned above, resulting from contact by boat propellers and boat hulls with the grass beds or erosive prop wash caused by operation of boats in water so shallow that the propellers are too near the bottom, the Applicant has agreed to a condition which will effectively remove boats from the seagrass bed area, provided it is strictly enforced. That condition would provide that boats and the slips in which they would be moored cannot be landward of 600 feet off shore of the mean high water line along the sides of the seaward extending dock. All boat slips are to be located seaward of that point. The Petitioners, however, raised a valid point that, the dock being so long, the natural tendency of boat operators would be to moor their boats along the sides of the dock as close into shore as boat operation is possible in order to more easily load and unload their boats. In order to prevent this problem from occurring, therefore, an additional condition should be imposed on the permit which would provide that the sides of the dock be enclosed by a fence out to the 600 foot mark and of such a configuration and type as to prevent boat operators from mooring boats to the sides of the dock and gaining ingress or egress from their boats on the dock shoreward of the 600 foot point mentioned above. In other words, if it is made impossible to enter or leave a boat from the dock in the area of the seagrass beds, this would substantially reduce the likelihood that the seagrass beds would be damaged by boats using the dock. Additionally, prominent signs should be posted on or in the vicinity of the dock announcing the necessity to avoid operating boats landward of the point mentioned above and the necessity of avoiding contacting the seagrass beds with boats or boat propellors. If this condition is adhered to and strictly enforced, as even Petitioner's expert witness concedes, it will prevent the chief source of adverse effects upon the public interest. An additional consideration in determining whether or not this project is contrary to the public interest concerns its effect upon navigation. This has already been discussed in the above Findings of Fact. Since this would be the only dock in the immediate area, it is found that the presence of the dock, even though it extends a significant distance seaward of the shore line, will still not pose a significant impediment to navigation. Additionally, as has been pointed out above, the public interest might be served in a positive way by the installation of the dock to the extent that it might prevent shrimp boats and other fishing boats pulling nets from using the shallow seagrass area which will help prevent uprooting and other damage to the grass beds caused by the nets and associated fishing gear. Finally, it should be pointed out that to a certain extent the project will positively serve recreational values and the public welfare, in the context of balancing the various public interest considerations, because at least half the boat slips will be reserved for public use and because the addition of such a marina or docking facility will enhance the public's ability to obtain recreational value from the State waters involved in East Bay by improving marine access to those waters for fishing, boating, skiing and other purposes. In short, reasonable assurances have been provided that the project is not contrary to the public interest.
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 the application of John E. Bravo for the dredge and fill permit at issue be GRANTED, provided that the terms and conditions enumerated in the above Findings of Fact are incorporated in the permit as mandatory conditions. DONE and ORDERED this 29th day of July, 1987, in Tallahassee, Florida. P. MICHAEL RUFF Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 29th day of July, 1987.
Findings Of Fact This hearing was occasioned by the Respondent's denial of (an) environmental permit(s) requested by the Petitioner, Baker Cut Point Company, a corporation owned by James C. Dougherty. The Respondent has asserted permit jurisdiction pursuant to Chapters 253 and 403, Florida Statutes, and attending regulatory provisions of Chapter 17, Florida Administrative Code. The Petitioner requested a formal hearing to consider the matters in dispute, and that hearing was conducted on the dates indicated before and in keeping with Subsection 120.57(1), Florida Statutes. The Petitioner owns land in Monroe County, Florida, identified as Buccaneer Point. This parcel of land is a peninsula which extends from the west side of Key Largo, Florida, and has as its essential features two interior lakes and well-defined mangrove stands to include red mangroves (Rhizophora mangle) and black mangroves (Avicennia germinans). This parcel of land is bordered on the north by Buttonwood Sound and on the south by Florida Bay, navigable water bodies. Respondent's Exhibit No. 1, admitted into evidence, depicts the present condition of the parcel of land, with the exception of proposals involved in the permit review process, which are the subject of this Recommended Order and the companion case of James C. Dougherty v. State of Florida, Department of Environmental Regulation, DOAH Case No. 80-1055. At present, the two lakes do not offer normal access to Buttonwood Sound and Florida Bay, nor do they offer an interior water connection between the two lakes. The southernmost lake does have intermittent water exchange with Florida Bay. Those lakes are identified as North Lake and South Lake. The Petitioner had initially applied for permission to place 75,000 cubic yards of clean limerock fill at the project site and indicated that the fill would be placed landward of the mean high water line. That fill would have covered approximately 17.56 acres in the residential subdivision. The application was made on October 27, 1978. See Petitioner's Exhibit No. 20, admitted into evidence. The Respondent issued an Intent to Deny the permit connected with that request, and that Intent to Deny was issued on April 3, 1980, asserting permit jurisdiction by the Respondent under the provisions of Chapters 253 and 403, Florida Statutes. See Petitioner's Exhibit No. 5, admitted into evidence. The Petitioner modified the permit application effective April 24, 1981. Under the terms of the revised permit application, the Petitioner would place limerock fill over 5.7 acres, including mangroves, constituting approximately 30,000 cubic yards of fill. Additionally, the applicant modified the permit request to include filling the exterior rim of the interior lakes to create a littoral zone and the placement of a berm at that exterior. See Petitioner's Exhibit No. 6, admitted into evidence. The project, as contemplated, allows for a preserve area of mangroves along the northern end of the peninsula and also employs a "pad" concept to preserve the mangrove acreage where fill is to be placed. Those "pads" for houses would be bordered by six- inch dikes to divert upland runoff which might find its way into the interior lakes on the property. The fill material to be placed in those areas, other than the lakes, would be placed above or landward of the line of mean high water, as determined by the mean high water line survey found in Petitioner's Exhibit No. 1, admitted into evidence, dating from December, 1975, and whose methodology was approved on January 15, 1980, for purposes of Chapter 177, Florida Statutes, through the offices of the State of Florida, Department of Natural Resources. This factual determination is also borne out by a review of the Petitioner's Exhibit No. 6, in pari materia with Respondent's Exhibit No. 1 and Petitioner's Exhibit No. 1. As the lakes are now constituted, the placement of the limerock fill at the fringe of the lakes would not be waterward of the line of mean high water; however, when the placement of this fill material is considered in view of the permit request made in Division of Administrative Hearings' Case No. 80-1055, which permit request attempts to open up the lakes by direct water connection to the aforementioned navigable water bodies, then the placement of the fill would be below the line of mean high water. See Petitioner's Exhibit No. 6. Therefore, treatment of the placement of fill for purposes of this case will be considered on a basis that the lakes remain landlocked and the matter of the placement of this fill will be a matter assumed in the Division of Administrative Hearings' Case No. 80-1055, dealing with an attempt to open those lakes by direct water connection to navigable waters of the State. Although the mangrove areas to be filled by the project are landward of the mean high water line, those mangroves are inundated by water at times and considered to be "submerged lands" adjacent to the State water bodies, Buttonwood Sound and Florida Bay. If the mangroves are removed, part of the ecosystem's ability to filter sediments and nutrients contained in stormwater runoff of adjacent upland areas and from tidal flows will be destroyed and will affect water quality considerations for adjacent open bay estuarine or marine systems. The extensive root system of the mangroves and associated vegetation assist in stabilization of estuarine shoreline sediments and attenuation of storm generated tides. Even though some of the mangroves in the proposed area for fill are in a stressed condition, i.e., a condition in which their growth is stunted, if left alone, those mangroves would flourish and provide the same water quality functions as healthy mangroves. A biologist presented by the Petitioner identified the number of mangrove species, the number of mangroves, the diameter of those mangroves and the height of canopies of the mangroves in areas of the project site. These items were summarized through the use of the Holdridge Complexity Index, which measures structural complexity of mangroves within the sites. See Petitioner's Exhibit No. 17, admitted into evidence. In particular, four such station pairs were studied and the pairs were constituted of a station within the basin of the mangrove stand and a station at the fringe of the mangroves. There was a site at each proposed waterway and a site at the northeastern and western points of the peninsula, the area of the proposed mangrove preserve. See Petitioner's Exhibit No. 6, admitted into evidence. This study indicated that fringe mangroves are more developed than the ones in the heart of the basins. This study also revealed that the upland fill would remove primarily black mangroves. The removal of the mangroves and placement of fill would be in furtherance of the creation of twelve to fourteen residential lots, the majority of which would be located on Florida Bay. See Petitioner's Exhibit No. 6. In furtherance of the intention to offer these lots for sale, the Petitioner has sold one of the lots on Florida Bay for $95,000 on or about June 2, 1981. If the proposed utilization of the property in question was not allowed, the Petitioner stands to lose money in his investment in the face of preliminary developmental expenses which, at present, exceed monetary returns from the sale of lots. The area in which the upland fill would be placed is porous limerock, which allows water to seep through and be transported underground to adjoining water bodies, both on site and off site, in addition to the runoff from the upland areas. To address these concerns, the Petitioner has planned for the installation of dikes in the various upland areas which are to be built to prohibit drainage into the remaining mangrove areas and ambient waters. The littoral zones around the edge of the inland lakes would promote marine and wetland vegetation which assists in the function of filtration of sediments and nutrients. On the subject of water quality considerations, the use of the clean limerock fill, which is calcium carbonate, would tend to stabilize seawater at its natural PH level, thereby allowing the specific conductance (measurement of salinity) of the lakes and surrounding ambient waters to remain in a natural state in terms of direct effects of the fill material. On the subject of contamination of water by copper, normally, seawater contains 3 micrograms per liter of copper. In a project such as this one, it is not expected that higher amounts of copper would be found, and the limerock contains only trace amounts of copper, if any. Specific testing done at the project site reveals less than 1 microgram per liter of copper in the North Lake and 4 micrograms per liter in the South Lake. Therefore, the activity is not expected to increase the levels of copper to the extent that measurements exceed 500 micrograms per liter in either the lakes or surrounding waters. In dealing with the substance of zinc, seawater contains as much as 30 micrograms per liter of zinc. Sampling by the Petitioner indicated 2 micrograms per liter in the North Lake and 8 micrograms per liter in the South Lake of that substance. The activity and the development is not expected to increase the levels of zinc to the extent that measurements exceed 1,000 micrograms per liter in either the lakes or surrounding waters. In sampling for lead content, the samples revealed less than 50 micrograms per liter of lead and the placement of limerock fill will not cause the amounts of lead in the lakes and surrounding waters to exceed 50 micrograms per liter. Testing for phenolic compounds at the site revealed that these materials were below established standards of the Respondent, and it is not expected that those standards will be exceeded through activities proposed in this permit process. The testing for oils and greases indicated less than 1 milligram per liter of oils and greases, which is below the State's standard of 15 milligrams per liter, and the activities proposed at the project site are not anticipated to exceed 15 milligrams per liter of oils and greases. Normal PH for coastal waters is 6 to 8.5, and the PH levels of the lakes and ambient waters in the area were in the range of 8, except for measurements done in the winter at the North Lake, where they were shown to be 7.5. The placement of limerock fill will not cause an imbalance in the pH readings. The activity as proposed will not add substances which are created by industrial or agricultural means or cause other discharges, colors or odors, or otherwise promote a nuisance condition in the ambient waters or the lakes. Measurement was made to toxic materials in the way of synthetics, organics or heavy metals. Those tests in the lakes and ambient waters showed heavy metals to be at low levels. There were no sources revealed of synthetics or organics. (The calcium carbonate found in the limerock fill would assist in breaking down lawn pesticides into phosphate.) In summary, the filling, as proposed, is not expected to promote the introduction of toxic substances into the lakes or surrounding waters. The placement of the clean limerock fill in the upland area is not expected to cause problems with turbidity in the lakes or ambient waters, which turbidity would exceed 50 Jackson Units above background. The filling will not affect dissolved, oxygen levels of the surrounding waters. Biochemical oxygen demand, the measurement of demand for oxygen of organic and chemical materials in the water, will not be influenced by the placement of the clean limerock fill related to surrounding waters. The limerock fill is not expected to introduce other oxygen demanding materials into the subject waters, such that dissolved oxygen levels would be lowered by BOD loading. There will be no problem with dissolved solids, in this instance, salts, due to the fact that calcium carbonate fill would not affect the dissolved solids in the ambient waters or in the lakes. Coastal water PH normally measures 6 to 8.5 and PH for open waters in the range of 1. Placement of calcium carbonate fill on the uplands would not cause the PH in the Class II waters in Everglades National Park, which is 300 feet east of Baker Cut Point, to vary above or below normal levels for either coastal or open waters. In addition, there would be no discharge of toxic substances from the calcium carbonate fill into the Class II waters herein described. Tests conducted in the vicinity of homesites utilizing septic tanks, and specifically as sampled in waters adjacent to Buccaneer Point and the subject lakes in a development known as Private Park and Buttonwood Sound , indicated less than one fecal coliform bacterium per 100 milliliters. See Petitioner's Exhibit No. 14, admitted into evidence. Anticipated setbacks for additional septic tanks to be associated with the buildup at the project site would be in keeping with the requirements of Monroe County, Florida, and harmful septic tank leachate is not expected to be a problem.
Findings Of Fact Petitioner James C. Dougherty owns property known as Buccaneer Point, which is a peninsula on the western side of Key Largo, Florida. This property is also known as Buccaneer Point Estates, and is a residential subdivision. On June 26, 1979, the Petitioner individually and as a trustee, applied to the Respondent for a permit to conduct dredging and filling activities at the aforementioned property, in particular, the project contemplated dredging access channels in Florida Bay and Buttonwood Sound and the connection of two existing inland lakes on the property site to those water bodies. After review, the Respondent denied the permit request and asserted permit jurisdiction in keeping with Chapters 253 and 403, Florida Statutes, and associated regulatory provisions found in the Florida Administrative Code. Having been denied the permit, the Petitioner requested a formal hearing to consider the matters in dispute and a hearing was conducted on the dates alluded to in this Recommended Order. The hearing was conducted in keeping with Subsection 120.57(1), Florida Statutes. The denial of the permit request was in the form of a letter of intent to deny dated May 27, 1980. See Petitioner's Exhibit No. 4, admitted into evidence. Following the receipt of the letter of intent to deny, the Petitioner commenced a series of revisions to the project leading to the present permit request which is generally described in Petitioner's Exhibit No. 6, admitted into evidence. If the project were allowed, it would call for the dredging of access channels in Florida Bay and Buttonwood Sound, those channels to be 75 feet long and -5 feet N.G.V.D., with side slopes of 1:3. Additional inland canals would be dredged to connect the access channels with the interior lakes, the north channel being 100 feet wide -6 feet N.G.V.D. and 400 feet long, and the south canal being 62 feet wide -6 feet N.G.V.D., and 225 feet long. Side slopes of the canals would be 1:3. The project also intends the connection of the two interior lakes by the excavation of a 162-foot long by 50-foot wide connection or plug at a depth of -5 feet N.G.V.D. The material from this excavation of the plug would be used as ton soil on the uplands. Finally, the permit proposes the shoaling of the North Lake on the property to -15 feet N.G.V.D. by the use of clean limerock fill. Through its opposition to the project, the Respondent has indicated concerns that bay grass beds would be damaged over the long term by boats as a result of the dredging of proposed channels and canals; a concern about increased BOD demands which would lower water quality following the long-term accumulation of organic materials in the channels. The Department also contends that construction of the south channel would destroy productive grass beds and "vegetated littoral shallows," which now serve as a nursery and feeding ground for numerous invertebrates. Respondent believes that the north channel would eliminate an area of mangrove wetlands which filters nutrients and toxic materials and serves as a nursery and feeding ground for estuarine organisms and wading birds. The Respondent also feels that the north channel would disturb a stable mangrove humus peat band, which now supports large numbers of invertebrates and which band extends along the northern shoreline of Buccaneer Point. The Department, in discussing the acceptability of the permit, has expressed concern that bottoms adjacent to the north channel would be harmed by increased erosion and sedimentation of the disturbed mangrove peat. Respondent has further stated that water in both interior lakes is now in violation of water quality standards and that water quality data shows high oxygen demands. The Respondent has put at issue the Petitioner's hydrographic report on the flow-through lake system, citing what it believes to be errors in the report. The Respondent has expressed specific concern about water quality standards as set forth in the following rules: Rule 17-3.121(5), Florida Administrative Code, Bacteriological Quality; Rule 17-3.121(7), Florida Administrative Code, Biological Integrity; Rule 17-3.061(2)(b) Florida Administrative Code, BOD; Rule 17-3.121(14), Florida Administrative Code, Dissolved Oxygen; Rule 17-3.121(20), Florida Administrative Code, Nutrients; Rule 17-3.061(2)(j) Florida Administrative Code, Oils and Greases; Rule 17- 3.061(2)(1), Florida Administrative Code, Phenolic Compounds; Rule 17-3.121(28), Florida Administrative Code, Transparency; and Rule 17-3.061(2)(a), Florida Administrative Code, Substances. The Respondent indicated that it felt the project would be adverse to the public interest because it would cause erosion, shoaling, or creation of stagnated areas of water, would interfere with the conservation of fish, marine life and wildlife or other natural resources, and would result in the destruction of oyster beds, clam beds or marine productivity, including destruction of natural marine habitats or grass flats suitable as nurseries or feeding grounds for marine life, including established marine soils which are suitable for producing plant growth of a type useful as nursery or feeding grounds for marine life. The project was also thought by the Department to be not in the public interest because it would reduce the capability of the habitat to support a well-balanced fish and wildlife population because it would impair the management or feasibility of management of fish and wildlife resources. The Petitioner has employed hydrographic engineers to conduct a study of the flushing characteristics of the system, should the access channels, canals and interior connections be allowed. It is an undertaking on the part of the Petitioner dealing with physical characteristics of the waterway and the forcing conditions in and around the site, which include tidal flow, wind-driven flow and mean sea level changes. The two State water bodies at the site, Buttonwood Sound and Florida Bay, are separated by the project site and other islands at the northern tip of the project. The effects of this separation changes the arrival time of high tide at the northern and southern extremities of the project site promoting a mean sea level surface difference between Buttonwood Sound and Florida Bay. The sea level difference or "head" assists in generating flow in the sense of moving the water from the high to the low elevation. To gain an exact measure of the hydraulic head, tidal gauges were placed at the northern entrance channel and in the southern entrance channel. The use of these gauges over a period of time allowed the determination of the spring and neap tide conditions. The "head" differences finally arrived at by calculations by the Petitioner's experts assisted in the creation of a mathematical model to determine flows in the water system. This lead to an estimate of flushing time of 2 1/2 days. See Petitioner's Exhibits 7-9,admitted into evidence. In turn, an estimation was made that approximately half of the flow which presently flows through Baker Cut, at the project site, would be diverted to the waterway system if constructed and this in conjunction with other calculations led to the conclusion that the flushing time was 3 to 4 days as opposed to the 2 1/2 days arrived at by the mathematical system. See Petitioner's Exhibit 10, admitted into evidence. The estimate of 3 to 4 days was the more current study and was premised upon conditions of an adverse south, southeast wind which would cause the water to move north, absent current conditions, as opposed to this south direction which was the normal direction of movement. The Petitioner also examined the flushing characteristics of similar projects which were not as favorable because of a lack of "head" differences which assisted in the flow of the water. Based upon the results of the studies conducted by Petitioner's experts, the flushing time of the system is found to be 3 to 4 days. While there is some correlation between a short flushing time for a water system and the water quality within that system, examination of other channel systems in the Florida Keys indicates that short flushing times do not always cause the waters to meet State water quality standards. For that reason, water quality considerations must be dealt with bearing in mind the physical characteristics of the system extant and as proposed using flushing time as a part of the equation. Those specific water quality criteria will be addressed in subsequent portions of these findings. Tests conducted by the parties dealt with the amount of dissolved oxygen in waters at the project site, and revealed dissolved oxygen levels of less than 4 parts per million, even when testing at depths less than 15 feet. This condition is one which is not unusual for natural water systems which have remarkable stability and are not the subject of flow or flushing, as example in mangrove forests. If the system were open, dissolved oxygen levels in the interior lakes would improve, though not necessarily to a level which no longer violates State water quality considerations related to dissolved oxygen levels. On the related subject of BOD or biochemical oxygen demand, that demand placed on oxygen in the water biochemicals or organic materials, the system as it exists and as proposed does not appear to cause excessive BOD, notwithstanding an 8 to 12 foot wide band of peat substrate in the area of the North Lake wall. Although the biochemical oxygen demand related to the layer of peat in the lake's system in its present state presents no difficulty, if the water system were open this peat layer would cause a significant amount of loading of biochemical oxygen demand in the lake system and eventually the surrounding water bodies. On the question of nutrients in the marine system, reflected by levels of phosphorus and nitrogen or variations impact the compensation point for the North Lake. In fact, there would be improvement in transparency or clarity for both lakes. Nonetheless, in the short run, the turbidity problems associated with the placement of clean limerock fill over the flocculent peat material would violate the transparency standard in that location. On the subject of toxic substances, meaning synthetic organics or heavy metals in sea water, tests by the Petitioner at the project site and comparison site demonstrated that those substances would not exceed the criterion related to those materials. On the subject of fecal coliform bacteria, water quality samples were taken at the project site and a comparison site. The residences now at the project site and those at a development known as Private Park use septic tanks. In view of the porous nature of the limerock foundation upon which the residences are built and in which the septic tanks are placed, the possibility exists for horizontal movement of the leachate into surrounding waters of the project site and the landlocked lakes; however, this movement is not dependent upon the opening of a flow-through system at the project site. Moreover, tests that were conducted in the comparison site and project site reveal less than one fecal coliform bacterium per 100 milliliters and if the system were open, the circulation in the lakes would lower the residence time of leachate. In describing the habitat afforded by the interior lakes as they now exist, the North Lake does not afford animals or fish the opportunity to colonize, because there are no areas where they may disappear into the lake. This limits the opportunity for habitat to those animals who have their entire life cycle in a landlocked system, and necessarily of those substances in the water, water quality standards for nutrients will not be substantially altered by the proposed project. In other words, the project will not cause an imbalance in natural aquatic flora or fauna population, by way of advent of phytoplankton bloom leading to eutrophy. The nutrient samples taken in the interior lakes demonstrate normal sea water levels and those levels outside the lake were low and the flow-through system is not expected to raise nutrient levels. Sampling for oils and greases in the comparison waterways where residential development had occurred in the lakes and ambient waters at the site, did not indicate problems with those substances in the sense of violation of State water quality standards. Sampling for phenolic compounds at the comparison sites and at the lakes and ambient waters at the project site showed less than .001 micrograms per liter in each instance of the sample. There are no sources or potential sources of phenols at the site. On the question of the State water quality dealing with transparency, that standard requires that the level of the compensation point for photosynthetic activity shall not be reduced by more than ten percent (10 percent) compared to natural background levels. The compensation point for photosynthetic activity is the level at which plant and animal respiration and photosynthetic activity are equal. In static state, the Petitioner's analysis of this criterion revealed that the North Lake compensation point would be below 15 feet and the South Lake would have no compensation point, due to its shallow nature. In the long run, the opening of the proposed connections in the planned development together with the shoaling, would not negatively excludes animals with a long larva stage. Examination of comparison sites pointed out the possibility for colonization at the project site should the waterways be opened. Specific testing that was done related to colonization by fishes, in particular sport and commercial fishes, demonstrated that those species increased in richness, density and diversity if a system was opened by channels and canals. In addition, the comparison of this project site and systems similar to that contemplated by the open waterway indicated that sea grasses would increase after a period of years if the system were open. Sampling was conducted in substrates to gain some understanding of the effect of the proposed project on the Shannon Weaver Index, i.e., whether there would be a reduction by less than 75 percent of established background levels. Although there would be no problem with the biological integrity standard related to South Lake and its waterway, the North Lake and waterway system could be expected to be in violation of that index due to the present circumstance as contrasted with that circumstance at the point when water flowed through. If the waters were opened to the project site, marine biological systems on the outside of the interior lakes would be given an opportunity to use those lakes as a nursery ground or spawning site for fishes, a refuge in cold weather conditions and a site for predators to find prey. If the lakes were opened to the outlying areas, alga, grass populations, mobile invertebra, plankton and other forms of life could utilize the interior lakes. In the area where the north canal or inland canal would be placed are found red mangroves (Rhizophora mangle) and black mangroves (Avicennia germinas) . The mangroves are frequently inundated by tidal waters and are the most mature and productive of the mangroves which are found at the property site. Some of those mangroves are located waterward of the line of mean high water and would be removed if the project is permitted. The mangroves at the project site provide filtration of sediments and nutrients contained in stormwater runoff from adjacent upland areas, as well as from tidal flows. This filtering process is an essential part of the maintenance of water quality in the adjacent open bay estuarine or marine system. Nutrients in the tidal waters, as well as runoff waters, are settled out and in the sediments retained by the mangrove roots and are transformed into vegetative leaf matter by the mangroves as they live and grow. The root systems of the mangroves and their associated vegetation provide stabilization of estuarine shoreline sediments and attenuation of storm-generated tides. These mangrove wetlands provide unique and irreplaceable habitats for a wide variety of marine as well as upland wildlife species. The mangroves also contribute leaf or detrital matter to the surrounding State waters and estuarine system in the form of decayed leaf litter. This organic component forms the basis of the marine food chain and is used directly for food by a variety of marine organisms, including small fish. Commercial and sports fish species feed directly on the mangrove detritous or on the fish or other forms of marine life that feed on that detrital matter. In removing the mangroves, the applicant causes a loss of the function which those plants provide in the way of filtration and the promotion of higher water quality and causes biological impact on marine organisms, to include sports and commercial fishes. In the area of the north access channel, there exists a band of stable mangrove peat which is 50 to 75 feet wide and one to two feet thick. Waterward of this expanse of humus is located a sandy bottom vegetated by turtle grass and other sea grasses and alga. The turtle grass in the area of the proposed north channel serves as a nursery and feeding ground for a rich and diverse aquatic community, including species of oysters, clams and other mollusks, as well as commercial and sports fish. This grass also filters and assimilates contaminants in the water column and serves to stabilize sediments to prevent turbidity. Dredging would destroy the turtle grass beds and their functions. These impacts on mangroves and sea grasses are significant matters, notwithstanding the fact that the possibility exists that mangroves would repopulate in the area of the north channel and North Lake, together with the repopulation of sea grasses in that area after a period of years. The south waterway would cause the removal of certain sea grasses, which could be expected to revegetate. Moreover, at present, the sea grasses in this area are sparse due to the shallow waters in that area, which waters are too warm for sea grasses to thrive. Construction of the access channel would result in increased erosion and sedimentation based upon boat wake wash and in turn allow for adverse impact on the biologically productive bay bottom. Water quality degradation can be anticipated because of the erosion and leaching of dissolved particulate material from the disturbed peat band at the shoreline and into shallow waters in the bay and into the North Lake. Transition from the inland channels to the bay side access channels at the north and south will be box cut at the mean high water line and in view of the fact that the inland channels are 100 feet wide and the bay side access channels are only 50 feet wide, erosion can be expected, causing turbidity.
Recommendation Based upon the findings of fact and conclusions of law recited above, it is recommended that petitioner's application for a permit to connect his canal to the Caloosahatchee River be DENIED. Respectfully submitted and entered this 22nd day of December, 1976, in Tallahassee, Florida. DIANE D. TREMOR Hearing Officer Division of Administrative Hearings Room 530, Carlton Building Tallahassee, Florida 32304 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 22nd day of December, 1976.
Findings Of Fact The Respondent/Applicant, Jeffrey David Evans, applied to the Department of Environmental Regulation and the Army Corps of Engineers for a permit to construct a dock and boathouse as depicted on Respondent's Exhibit 1. The proposed length of the dock and boathouse is sixty feet from the seawall marking the landward boundary of the Halifax River and the waterward boundary of the Respondent/Applicant's property. The Department of Environmental Regulation advised Evans as well as the protesting Petitioner on March 9, 1981, of its intent to issue the permit. The Army Corps of Engineers issued a general permit numbered SAJ-20(MOD) on September 4, 1979, also authorizing construction of the proposed dock with the condition that it not extend in a waterward direction to a water depth contour deeper than four feet at mean low water. The Petitioner herein timely petitioned for a hearing protesting the decision by the DER to grant the permit. The parties do not dispute and indeed have stipulated that there will be no adverse impact on the conservation of fish and wildlife in the area and no significant chemical, biological or physical alteration of the state waters and marine or aquatic life involved. In short, it was stipulated that there are no adverse environmental impacts of any kind to be occasioned by construction of the project. Mr. James Morgan of the Department staff was qualified as an expert witness in aquatic ecology and the evaluation of dredge and fill projects. He testified at the hearing and established that the Respondent/Applicant had provided affirmative reasonable assurances to the Department that the proposed project would not result in any violations of state water quality standards and that the proposed project would not result in interference with the conservation of fish and wildlife in the subject area or the capability of the local aquatic habitat to support such fish and wildlife. Mr. Morgan also testified that reasonable assurances had been provided by the Respondent Applicant that the proposed project would not create a navigational hazard or a serious impediment to navigation, and that an unobstructed navigable channel would remain after the project was constructed. There being no question that affirmative reasonable assurances have been provided that no state water quality standards will be violated and that no other adverse environmental impacts will occur within the purview of Chapter 403, Florida Statutes, or Chapter 17, Florida Administrative Code; the permit in this regard should be granted. A question remains, however, regarding the maximum length the dock should achieve in a perpendicular direction from the seawall of the Respondent/Applicant's property out into the river. Evidence propounded by the Department regarding a six-foot water depth off the end of the proposed sixty- foot dock site is based upon hearsay information received from a Department employee other than the witness who testified, who in turn received it through a telephone conversation with, another party with no evidence that soundings or other types of survey were made. Mr. Evans' own testimony establishes that he measured some six and eight-foot depths in the natural channel involved herein, but his testimony is not specific enough in reflecting at what points in that channel, in relation to the site of the proposed dock, he measured those depths nor at what stage of the tide he measured them. It is established in the record that there is approximately a one-foot rise and fall between mean low water and mean high water at the subject site. The only access by navigation to the Petitioner's home from the main channel of the Intracoastal Waterway is by means of a natural channel running in a northerly direction parallel and immediately in front of the Petitioner's home and the applicant's home and inshore from a large sand bar covered with oysters which is a permanent oyster bar protruding from the water at low tide. The channel continues from the Petitioner's home northerly and parallel to the applicant's home and seawall until it reaches the northern terminus of the sand bar. From that point a boat navigating the channel can turn out into the main channel of the Intracoastal Waterway. Unrefuted evidence propounded by the Petitioner in the form of a "multi-sounding" depth survey established that the channel's depth at mean high tide ranges from four to five feet in front of the Respondent/Applicant's property (See Exhibit 13) The Petitioner established that access to the Intracoastal Waterway is only feasible through the subject channel running in front of the Respondent/Applicant's property. The Petitioner established that the channel begins with a depth of four feet at low tide or five feet at high tide as its landward boundary which lies fifty-two feet from the Respondent/Applicant's seawall. Thus, a dock extending the proposed sixty feet from the seawall would approach the middle of the subject historic channel and would constitute an impairment to navigation of that channel. In apparent recognition of the question of navigability of this historic channel, which was shown to have a depth of five feet at mean high tide, the Corps of Engineers has issued a permit to the Respondent/Applicant to construct his dock to a point no farther waterward than the four-foot mean low water depth contour of the river. This would allow the dock to extend to the boundary of the channel and would thus allow a dock to be constructed fifty-two feet in a perpendicular direction from the Respondents Applicant's seawall. The parties agree that four feet of water is required for navigability in and around the subject, historic channel. Thus, if the dock extended to the depth of four feet at low tide, which would be five feet at high tide, it would extend into the navigable channel and not allow a sufficiently safe distance waterward of the end of the dock for boats to turn around the end of the dock to negotiate the canal adjacent to the Petitioner's home, especially if Evans' boat is moored at the end of the dock. Accordingly the dock should only extend to that point, denominated on Exhibit 13, which is characterized by a depth at high tide of four feet and which lies six feet landward from the fifty-two-foot extent of dock which the Corps of Engineers' permit would allow. Thus, if the dock were to be built forty-six feet in a perpendicular direction from the seawall an additional six feet would be allowed for the mooring of the Respondent/Applicant's boat off the end of that dock without unduly obstructing navigation in the channel. It is noteworthy in this regard that no witness from the Corps of Engineers, or who was instrumental in the approval of the Corps of Engineers permit, testified at the hearing.
Recommendation In consideration of the foregoing findings of fact and conclusions of law, the evidence in the record, the candor and demeanor of the witnesses and pleadings and arguments of counsel, it is RECOMMENDED: That the Department enter a Final Order granting the requested permit authorizing construction of a private dock and boathouse on the Halifax River in Port Orange, Volusia County, Florida, by Jeffrey David Evans, provided however, that said dock shall not extend a greater distance than forty-six feet in a direction perpendicular to the Respondent/Applicant's seawall on the waterward margin of his property on the Halifax River.

The Issue The issues to be resolved in this proceeding concern whether the Respondent Gate Petroleum Company (Gate) has provided reasonable assurances that Water Quality Standards will not be violated by the proposed modification of Gate's dredge and fill permit No. 160462149 and whether Gate has provided reasonable assurances that the proposed modification of that permit will not be contrary to the public interest, nor be the occasion of adverse cumulative impacts to water quality or public interest considerations so as to make this project contrary to the public interest.
Findings Of Fact The Respondent Gate Petroleum Company, by and through its wholly-owned subsidiary, Gate Maritime Properties, Inc., proposes to construct a ship- berthing facility for two ships adjacent to Blount Island Channel, along the southeastern portion of Blount Island, in the St. Johns River, in Duval County, Florida. The proposed facility would provide for the berthing of two ships of the United States Navy Military Sea-Lift Command in conjunction with the mission of the Navy's Rapid Deployment Force. The proposed facility would be located along the southeasterly portion of "Cut A" of the Blount Island Channel and will consist of a "T-head Pier", a breasting dolphin and cat walk and two mooring dolphins. The pier would be connected to the land by an approach trestle. The facility involved will be constructed by the insertion of concrete pilings into the bottom of the Blount Island Channel and in the adjacent upland, which would support concrete decks and caps. Removal of dredged material will be necessary to accomplish the project and will be performed by a floating hydraulic dredge with associated "Cutter Head." The resulting dredged material would be disposed of in a diked spoil area on either Blount Island or at the Dayson Spoil Site adjacent to the mouth of Clapboard Creek. The Respondent Gate currently holds a DER dredge and fill permit, No. 160462149, authorizing the removal of approximately 3.4 million cubic yards of dredged spoil and the installation of an associated 5,000 feet of shoreline bulkhead. The proposed installation of the pier and mooring facilities would result in a modification of that permit so that approximately 1,000 feet of shoreline bulkhead and most of the related dredging will be unnecessary and not performed. Instead, approximately 7,100 cubic yards of dredging would be necessary, without the necessity for bulkheading. The remaining shoreline bulkhead and dredging authorized under the above permit would be rendered unnecessary and replaced by the addition of two additional T-head piers and associated dredging at some indefinite time in the future. The additional piers and dredging are not involved in this permit modification application and are not before the Hearing Officer at this time. The Blount Island Channel of the St. Johns River, the St. Johns River and Clapboard Creek are classified as Class III surface waters of the state pursuant to Sections 17-3.081 and 17-3.121, Florida Administrative Code. It has been established by stipulation of the parties that the proposed modification of the dredge and fill permit will not adversely affect navigation nor the flow of water in the Class III state waters involved. It is also stipulated that the proposed modification will not adversely affect historical and archaeological resources pursuant to Section 267.061, Florida Statutes. It is stipulated as well that the discharge of effluent from the Dayson spoil site will not violate water quality standards at the point of discharge in the Fulton-Dames Point Cut. On March 22, 1989, the Florida Department of Environmental Regulation issued its intent to approve the proposed permit modification so as to allow the elimination of the previous requirement in the permit to monitor for copper at the site of the effluent discharge; the relocation of the Blount Island spoil site effluent discharge and the construction of a T-head pier on the southeast side of Blount Island adjacent to the Blount Island Channel. The Department did not initially grant the request to relocate the Dayson spoil site effluent discharge from the Corps of Engineer Channel (Dames Point Cut) to the mouth of Clapboard Creek. On January 31, 1986, Gate was issued permit No. 160462149, pursuant to Chapters 403 and 253, Florida Statutes, with an expiration date of January 31, 1991. It authorizes the dredging and filling on and adjacent to Blount Island referenced above. The permit authorizes those operations in two phases, consisting of new dredging of approximately 300,000 cubic yards in the existing slipway and test area to obtain a project depth of 40.2 feet mean low water. Maintenance dredging was authorized in the amount of approximately 1,850,000 cubic yards in the slipway to maintain the above-noted project depth. New dredging of no more than 3 million cubic yards from the northeastern and southern margins of Blount Island to a depth of 38 feet mean low water (MLW) and 20 feet MLW on the northeastern and southern portions of Blount Island respectively, with attendant maintenance dredging, was authorized. The permit also allowed he construction of shoreline bulkheads along the eastern and southern margins of Blount Island. That 1986 permit also required disposal of dredged material from both phases of the project into diked areas on Blount Island and the existing diked off-site disposal area known as the Dayson Site, near the mouth of Clapboard Creek. Effluent from both sites was to be discharged to the Fulton-Dames Point Cut. Effluent from the Dayson site was to be discharged to the Fulton-Dames Point Cut or routed by pipeline to the Blount Island disposal site for additional treatment prior to discharge. All dredging under the 1986 permit was to be done via a suction, cutter-head dredge apparatus, with the speed of the cutter-head to be controlled so as to prevent excessive turbidity; and with all dredged material to be placed in diked areas, with the effluent discharge being conducted over adjustable weirs. The dredging of the approximately 7,100 cubic yards of material associated with the modification application at issue will be performed with the same type of equipment. Both spoil disposal sites have sufficient capacity for disposal of the material involved with the construction of the T-head pier. The effluent or "de-watering water" generated from the disposal of the dredged material at the Dayson on site will be discharged through a pipe under the St. Johns River to a point near the confluence of the Dames Point Cut and the Old River Channel. That material will consist of approximately 10 percent dredged solid material and 90 percent water. The Dayson disposal site is surrounded by dikes 24 feet high and 120 feet wide at their base. They are so constructed that there will be no discharge of effluent from the Dayson disposal site to Clapboard Creek. Since 1974, over four and one-half million cubic yards of material have been disposed of at the Days on site without any violation of state water quality standards in the creek or the adjacent salt marsh. The entire 7,100 cubic yards of dredged material, together with related water could be placed in the Dayson disposal site without causing any discharge. Gate Maritime Properties, Inc. has a five-year lease agreement with Leadermar, Inc. which will operate the T-head pier as a berthing facility for the two ships. The lease was scheduled to commence July 22, 1989. Under the terms of the contract awarded by the Navy to Leadermar, Inc., Gate, or its lessee, is required to maintain a 110 foot, safe working area surrounding the vessels for operation of tugs, lighterage vessels and fendering operations. The contract with the Navy does not require, however, that the safe working area be maintained at a depth of minus 32 feet "mean lower low water" as shown by Gate Exhibit 6 in evidence. 1/ Given the findings made infra., concerning the lack of adverse water quality or public interest impacts caused by the dredging, and the paucity of any attendant suspension of bottom materials in the operation of the ships to be berthed at the proposed facility, the issue of whether the contract with the Navy requires a depth of minus 32 feet "mean low water" or "mean low low water", a reputed difference of 1.03 inches according to the rebuttal exhibit of Respondent Gate, neither Gate's position nor the Navy's reputed position regarding this apparent contractual dispute item, if carried out, would have any adverse water quality or public interest impact in the context referenced in these findings of fact and conclusions of law. The fact remains that Gate has applied for authority to recede from the massive dredging project presently authorized in the existing permit, to stipulate by this modification application that it only seeks to dredge 7,100 cubic yards of material in the area involved. Based upon the depth established by the marine survey conducted by Bennett, Wattels and Associates, there will be an adequate safe working area for tug boats, fuel barges and lighterage vessels, as well as the ships themselves, for operations involving the berthing facilities. See Gate Exhibit 5 in evidence. If the requested modification is granted, Gate will not dredge more than 7,100 cubic yards of material for construction of the pier and related facilities and in order to provide a safe working area as required under Leadermars contract with the Navy. Indeed the amount of material to be dredged for the construction and operation of the T-head pier was based upon the above- referenced Marine survey, unrefuted evidence in this record. The volume of material was calculated by using the Marine Survey depths and the "average end area method," a widely accepted method of such calculation in the marine engineering and construction field. Further, Gate adduced the only substantial evidence in this record concerning the issue of the amount of dredging involved or the extent of the dredged area, as that relates to the "safe working area" and other issues. Water Quality Gates' consulting experts performed various chemical and sediment analyses in the project area in order to establish a general composition of bottom sediments and to establish the likelihood of suspension of any toxic substances or pollutants in those sediments as a result of the dredging operation or the operation of the ships and berthing facilities. Those analyses, and their results, in evidence in this record, were unrefuted. The bottom sediments in the vicinity of the project area are predominantly fine sand with small fractions of silt. In general, the dredged material is most likely to be free from chemical or biological pollutants where it is composed of sand, gravel or other naturally occurring inert materials, as opposed to large percentages of organic materials, which were not shown to exist in the vicinity of the project site. Based upon the characteristics of the bottom sediments in the project area, there will be no re-entrainment of toxins or pollutants which night presently be sequestered in the sediments due to construction, dredging operations or the operations of the berthing facility and ships involved. An elutriate test was performed to predict the effect on water quality from temporary suspension of the bottom sediments during the dredging operation itself. Elutriate testing is a widely recognized, conservative estimate of contaminant releases, caused by dredging, into a water column. The parameters tested for are those specified in the Department's rules for Class III waters and include cyanide, mercury, silver cadmium, selenium, barium, beryllium, nitrogen, (unionized NH3, NO2, total TKN), fluoride, copper, iron, nickel, zinc, aluminum, pesticides, herbicides and PCBs (polychlorinated biphenyls). The elutriate test results did not reveal any excess ion of any of these parameters in terms of the state water quality standards or as to prevailing natural background levels. There are no PCBs, hydrocarbons, heavy metals or pesticides shown to be sequestered in the bottom sediments of the Blount Island Channel in the vicinity of the proposed project. The chemical analyses was performed on composite elutriate samples of sediments which came from the area of the T- head pier location and the area north of the pier, where the propellers of the ships will be located and operated during test trials, after the ships are berthed at the site. Site specific chemical analyses and core borings were taken and compared with historical data or studies for these sites and found to be consistent with them. There is no likelihood of sequestered contaminants in the bottom sediments which would be released, with deleterious effect on water quality, as a result of the action of the dredge equipment or the operation of the ships after the facility is installed. Cutter-head, hydraulic pipeline dredges are not significant generators of turbidity. They are an efficient means of performing dredging and are designed to loosen and remove material from the bottom substrate, without disturbing or redistributing the dredged material around the dredge apparatus in the water column. The use of the hydraulic pipeline dredge will result in minimal water quality disturbance and any dredge-induced turbidity will be of a transitory, short-term nature. It would be localized in the immediate vicinity of the dredge's cutterhead in any event. Ambient water quality conditions can be expected to return to normal background levels in a matter of hours following cessation of the dredging activity. It is estimated by Gate's consultant witnesses that the dredging activity might be accomplished in approximately one day. It has thus been established that the relevant stage water quality standards will not be violated by the action of the dredging equipment and the dredging operation itself. Water Quality Impacts of Facility Operation The two ships of the military sealift command which are to be berthed at the proposed T-head pier are 948 feet in length and approximately 105 feet in beam. They are equipped with two main engines and two propellers. The propellers are 22 feet, 11 and 9/16 inches in diameter. The ships will be in what is known as "reserved operating status". The ships will go through a dry- docking procedure at a local shipyard approximately every two years for major overhauls, repairs and painting. Such maintenance work will not be performed at the project site. The ships will, however, undergo periodic "dock trials" while berthed at the facility. The dock trials will be conducted on a quarterly basis if the vessels have not been out on a mission in that quarter of the year. The dock trial procedure calls for the main propulsion powerplants of the ships to be put into operation and evaluated. Both main engines are tested under this procedure for approximately one hour, at ten revolutions per minute (rpm) ahead and astern. The tests are to be conducted by civilian personnel retained by the Navy or its contractor, with all appropriate safety precaution being taken. These include, but are not limited to, the manning of the bridge during tests by a master or chief mate and by rotating one engine ahead simultaneously with the other engine being rotated astern. The ships are also equipped with onboard, internal sewage treatment plants so as to prevent the discharge of pollutants to state waters. Only routine maintenance or repair work will be performed on the ships at the lay birth facility. The ships will be refueled at the facility from time to time with "bunker c" or diesel fuel brought in by barges. The barges will be conveyed by tugboats of no more than 16 feet draft. The fueling operation will be governed by the U.S. Coast Guard regulations and are performed by Coast Guard certified and licensed personnel. Dr. Neal Boehnke was accepted as an expert in the field of chemical analysis of water and testified on behalf of the Petitioner. In his opinion, water quality in the facility of the proposed project is poor and may contain elevated hydrocarbon levels. His opinions, however, are based upon 1982 and 1983 reports of sampling results allegedly obtained by the City of Jacksonville Bioenvironmental Services Division and the DER, as well as the study entitled "Survey of Hydrocarbons and the Lower St. Johns River in Jacksonville." These documents were not introduced into evidence. While it is true that an expert may base his opinion on facts and data made known to him in the normal course of his practice at or before trial and that those facts or data may be relied upon by him in formulating his opinions, it must be demonstrated that those facts and data are "of a type reasonably relied upon by experts in the subject to support the opinions expressed." See Section 90.704, Florida Statutes. In this proceeding, it was not established by competent evidence or testimony at hearing that the facts or data derived from these documents were of such a type as to be encompassed by this statutory section and thus they cannot serve as a legitimate basis for Dr. Boehnke's opinion. They otherwise constitute inadmissible hearsay, not sufficient to support a finding of fact on the water quality impacts from the proposed project and they do not constitute corroborative or explanatory hearsay related to any accepted, competent, substantial evidence in this record for purposes of the hearsay admissibility provision in Section 120.58, Florida Statutes. Therefore, Dr. Loehnke's opinion concerning alleged elevated levels of hydrocarbons in the water at the project site is not credited and is rejected. Dr. Allan Niedororda was accepted as an expert in the fields of oceanography, hydrology and hydrologic assessment. He conducted a study on the potential impact to water quality in the Blount Island Channel which might result from the dock trials to be carried out as a part of the routine maintenance and testing of the ships. His study evaluated the degree to which the propeller wash from the dock trials might entrain and transport bottom sediments, any related pollutants and the effect of this entrainment on water quality in the surrounding water column. His study consisted of field sampling and measurements of currents in the area, laboratory analysis and related data analysis. Bottom sediment samples from the project area were analyzed for particle size and grain size distribution according to standard, scientifically accepted procedures. The bottom sediments in the area of the project site are characterized by a sandy sediment of a fine to medium particle size characteristic. The bottom sediments largely consist of clean sand and small gravels, with some silt composition. The propeller wash which will be generated by the testing of the ships engines was computed to have a speed of approximately one half foot per second. Maximum speed will occur about three propeller diameters behind the plane of the propeller itself or about 72 feet behind the propellers. The bottom tip of the propeller with which the ships are equipped will be six feet off the bottom of the channel at low tide. At the point the propeller wash contacts the bottom, its speed will be approximately two tenths of a foot per second. Such a velocity will not be of sufficient force to produce such sheer stress on the bottom sediments as to entrain them or, that is, to displace them upward into the water column. Dr. Niedororda established that, even if the propeller wash is added to the natural velocity of the water currents at the project site, there would be no entrainment of the bottom sediments which he sampled in the project area. It has also been established that the routine, minor maintenance of the ships and dockage facilities involved in the permit application and the fueling and other operations associated with the berthing, testing, entry and egress of the ships from the proposed berthing facility will occasion no water quality violations, so long as appropriate Coast Guard regulations attendant to fueling and the prevention of the deposition of refuse and other wastes into the waters involved are observed. Any grant of the proposed permit modifications should be conditioned upon the strict observance of those regulations and procedures, especially with regard to the potential for spillage during fueling operations. Public Interest Standards Section 403.918(2), Florida Statutes provides that a permit may not be issued unless the applicant provides the department with reasonable assurances that the project is not contrary to the public interest. In determining whether this is the case, the Department must consider and balance the following criteria: Whether the project will adversely affect the public health safety or welfare or the property of others; Whether the project will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; Whether the project will adversely affect navigation or the flow of water or cause harmful erosion or shoaling; Whether the project will adversely affect the fishing or recreational values or marine productivity in the vicinity of the project; Whether the project will be of a temporary or permanent nature; Whether the project will adversely affect or will enhance significant historical and archaeological resources under the provisions of Section 267.061; The current condition and relative value of functions being performed by areas affected by the proposed activity. It has been established by stipulation that the project will not adversely affect navigation or the flow of water and that the project will not adversely affect significant historical or archaeological resources. Unrefuted evidence adduced by Gate and the Department have established that the project will not adversely affect the public, health, safety, welfare or the property of others, if the project is constructed, installed and operated as proposed in the modification application and as proved in this case. The conservation of fish and wildlife, including endangered or threatened species, or their habitats, as well as fishing and recreational values and marine productivity in the project area will not be adversely affected. No harmful erosion or shoaling will be caused by the installation or operation of the project facility. In this connection, Dr. A. Quinton White, a member of the Board of Directors of the Petitioner, C.E.S., acknowledged in his testimony that the Manatee Protection Plan and Manatee Watch Program proposed to be inaugurated by Gate will adequately protect any Manatees frequenting the area. Manatees are an endangered species, but it has been established that the permit modification proposed, if installed and operated, will not adversely affect the conservation of Manatees or their habitat. The Petitioner adduced no evidence on this issue or any of the public interest criteria enumerated above. The area at the project site is characterized by fairly firm consolidated bottom substrata, characterized by very few submerged grasses. Due to the sandy, hard bottom in the project vicinity, there is a paucity of marine grass upon which Manatee could feed. Consequently, Manatees do not and are not likely to frequent the area involved at the project site as that might reflect on the likelihood of their injury or destruction due to operation of the ships and any attendant vessels. Dr. Niedoroda established that the project and the attendant operations of the ships will not cause harmful erosion or shoaling and witness Gary Tourtellotte, testifying for Gate, established that the effects of the construction and operation of the T-head pier on the benthic community and marine productivity in the vicinity of the project will not induce any adverse effect on those elements of the public interest standards involved. The Petitioner offered no credible or credited evidence of equivalent value which could contradict the evidence adduced by Gate on this aspect of the public interest standards. It is true that dredging of the bottom substrata will temporarily eliminate the benthic community within the dredged area itself. It was established by expert testimony, however, that the benthic community will rapidly re-colonize itself with similar organisms to a naturally occurring degree within approximately 6-12 months. The benthic community in the project vicinity is of a low density nature, with a low diversity of organisms. Those organisms occurring in the project site area are estuarine, marine benthic species commonly associated with sandy or silty bottom substrates. Because the area to be dredged is quite small or approximately .25 acres, and the dredging operations will be of short duration, approximately one day, the dredging operations will not have a significant adverse effect on the benthic communities occurring in the project area or in the adjacent St. Johns River. The dredging associated with the project will likewise not have a significant long-term adverse impact on fisheries resources or marine productivity of the Blount Island Channel or the St. Johns River. This is because the area to be dredged is minimal in size and does not contain critical marine benthic habitat. The turbidity generated will be minimal because the sediments are predominantly coarse sands and gravels. Because of this, any turbidity occasioned by the installation and operation of the proposed facility will be very brief and not of a sufficient significance as to violate water quality standards. In view of the hydrologic analysis in evidence concerning propeller wash effects, the bottom sediments at the ship mooring area will not be entrained or suspended in the water column to any significant degree due to propeller operation of the ships. Thus the benthic community in the mooring area for the ships will not be disturbed due to currents created by the operation of the propellers. In a similar vein, it has been shown that the dredging and operation of the T-head pier and mooring facilities, including the attendant conduct of periodic dock trials and the entry and egress of the ships will not violate the water quality criteria for biological integrity. Indeed, the periodic dock trials are shown to have no impact on the benthic community, the fisheries or marine habitat involved at the project site. It was neither shown that the dredging associated with the construction of the pier and berthing facilities will have any adverse impact on fin fish or shellfish in the project area. It has been established that the project will be of a permanent nature, but it has not been established that the current condition and relative value of the functions being performed by the areas affected by the proposed activity in terms of their functions as productive marine habitat, as furnishing fishing or recreational values and the like, will be adversely affected by the proposed project and attendant activity. Deletion of Copper Monitoring Requirement The 1986 permit authorizing the removal of approximately 3.4 million yards of dredged material with attendant extensive bulkheading in the Blount Island Channel requires also that Gate Monitor for copper every two weeks during discharges at the downstream boundary of the mixing zone for each point of a effluent discharge. Effluent from both the Blount Island and Dayson Disposal Sites is discharged into the Fulton Dames Point Cut. The Petitioner has stipulated that the discharge of effluent from the Dayson Spoils Site will not violate any water quality standard at that discharge point. Elutriate testing and other analyses submitted in support of the permit modification request to delete the copper monitoring requirement in the present permit have shown that there will be no violation of water quality standards as to copper, or any of the other water quality parameters involved due to any re-suspenions of bottom sediment during dredging. There will be no violation of water quality standards for copper, caused by the deposition of spoil, consisting of those bottom sediments, and the draining of effluent from the spoils site into the Dames Point Cut. The Department has independently verified the data submitted by Gate as a result of this testing and it has been established that there is no occurrence of any man induced pollutants in the sediments at the project site which will be deposited in the spoil site, (from which the effluent will be disposed of in the Dames Point Cut) which represents any elevation over natural background levels. The sediments to be dredged from the berthing area are not distinguishable from naturally occurring sediments and the copper values in the sediments to be dredged are no higher than those naturally occurring throughout the area. Thus there will be no adverse impact on the water quality occasioned by discharge of the effluent from the spoil site to the Dames Point Cut area due to copper occurring in the sediments or as to any of the other pollutants enumerated above. Thus, there has been no demonstrated necessity to continue monitoring the effluent from the spoil site for copper. In this regard, the Petitioner presented no evidence at hearing concerning the issue of whether copper monitoring should be continued or not. Cumulative Impact Blount Island was created in the 1950's and 1960's by the filling of its area with spoil material during the U.S. Army Corps. of Engineers' construction of the Fulton-Dames Point Cut-Off Channel. Since that time, port facilities and an industrial complex have been constructed on Blount Island. It is one of the principle port facilities for the City of Jacksonville. Under the 1982 DER dredge and fill permit issued to Off-Shore Power Systems, and later transferred to Gate in 1986, the developed area of the island adjacent to the original St. Johns River Channel (the Blount Island Channel) was required to be bulk-headed and the channel dredged to -38 feet MLW. The amount of material to be dredged in the old channel of the St. Johns River for construction of the vertical shoreline bulk head totalled approximately 3.4 cubic yards. The T-head pier involved in this modification proceeding, if constructed, would replace 1,000 linear feet of that shoreline bulkhead authorized by the present permit and would substantially reduce the amount or quantity of material to be dredged. Construction of the T-head pier, instead of the permitted shoreline bulkhead, will minimize dredging and the environmental impact of the facility. Gate has elected to rescind its plans to construct the shoreline bulkhead along the eastern shore of Blount Island, as authorized under the existing dredge and fill permit. Gate instead intends to seek future modification of its existing dredge and fill permit to substitute at least 2 additional T-head piers for all of the shoreline bulk head authorized for the eastern shore of Blount Island. The construction of the additional T-head piers will require substantially less dredging than is authorized under the existing permit. Instead of the 3.4 million cubic yards of dredged material authorized under the existing permit, associated with installation of the shoreline bulkhead, the amount of material to be dredged, if indeed 2 additional T-head piers were applied-for and constructed, would amount to only 269,000 estimated cubic yards, as opposed to the originally authorized 3.4 million. Kevin Pope, the DER witness, established that there are no other projects in the area, or reasonably expected to be located in the project area, which would create impacts in addition to or cumulative with the proposed permit modification project so as to create adverse water quality impacts or which would make this project, because of cumulative impact, contrary to the public interest. There are no other dredge and fill projects in the area of the proposed T-head pier which would adversely impact the waters of the Blount Island Channel and the St. Johns River. The proposed modifications are shown not to likely cause any adverse environmental results and, in fact, will result in an environmental benefit as represented by the agreed-upon recession from the extensive dredging and bulkheading authorized by the present permit. No evidence was adduced by the Petitioner to contravene that adduced by Gate and the Department, which establishes the lack of any adverse cumulative impacts to be occasioned by the proposed project, both as to water quality standards and the public interest standards involved in this proceeding.
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 approving the proposed modification to permit number 160462149 with the proviso that the conditions contained in the above findings of fact and conclusions of law be incorporated as specific conditions in the modified permit, including the additional condition agreed to at Final Hearing that the Manatee Protection Plan and Manatee Watch Program will be inaugurated and be incorporated as a specific condition in the modified permit. DONE and ENTERED this 11th of October, 1989, at Tallahassee, Florida. P. MICHAEL RUFF 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 12th day of October, 1989.
Findings Of Fact The Respondent Debra Flynn has submitted an application to the DER to construct a dock extending 190 feet waterward of the mean high water line of waters of the state, which would also extend 80 feet landward of the mean high water line through a transitional wetland area. The landward extent of the dock will completely span the DER's wetland jurisdiction at the project site. A raised "pad" of fill upon which the applicant's house would be constructed and a filled driveway, although originally a part of this application, has been altered in design by the applicant such that those two items have been removed from the geographical extent of the DER's jurisdiction and those two items in the proposed project are no longer at issue. The applicant's lot is approximately 300 feet deep by 100 feet wide. This lot is one of many similarly sized lots which border Niles Channel on the east and Nyles Road on the west, on Summerland Key. These lots vary in nature from tidally inundated mangrove wetlands to a combination of upland and transitional wetlands fringed by mangroves along the water's edge. The portion of the applicant's lot nearest to Nyles Road is primarily characterized by upland vegetation extending approximately 75 to 100 feet in an easterly direction from the road. The elevation gradually decreases toward the waterfront of the lot on Niles Channel, with buttonwood (Conocarpus erecta), dropseed (Sporobolus sp.), key grass (Monanthochloe littoralis), and sea daisy (Borrichia sp.) being the dominant species over most of the applicant's lot. Over the northern side of the property adjacent to adjoining lot 34, a pocket of black mangroves (Avicennia germinans) extends inland, nearly to the upland area described above. As the lot elevation drops toward the shoreline, mangrove growth occurs more frequently, culminating in a dense mangrove fringe bordering Niles Channel. This mangrove fringe becomes well established some 30 feet landward of the approximate mean high water line, being dominated by black and white mangroves. Waterward of the mean high water line, red mangroves dominate for a distance of approximately 30 feet out into Niles Channel. The landward portion of the dock would have only minimal environmental impacts on the transitional wetlands as established by DER's expert witness Meyer and witness Kephart. No contradictory evidence was submitted in this regard. The bottom of Niles Channel extending 65 feet waterward of the mangrove fringe area is characterized by a hard caprock substrate covered with somewhat coarse sediments and loose algaes. In addition to the loose algae, the bottom, attached marine life communities are characterized by red, brown and green algae, sponges, anemones and hard corals. Waterward of this initial 65 foot zone, a relatively narrow zone of seagrasses is encountered. This zone of seagrass extends about 15 to 20 feet in width, forming a somewhat broken, noncontinuous band extending from north to south across the front of the property. Within this seagrass band, the primary growth is turtlegrass (Thalassia testudinum). There are smaller amounts of Cuban shoalweed (Halodule wrightii). Continuing waterward of this seagrass growth, the vegetative bottom coverage decreases with sandy patches becoming larger and more frequent. The bottom profile also becomes more rough and irregular, characterized by the presence of dissolved limerock holes as well as outcroppings. These holes and outcroppings provide excellent habitat for shelter-dependent fish and invertebrate species, such as spiny lobster and stone crabs. The area constitutes-prime nursery habitat for spiny lobsters and stone crabs. Water depth where the dock, as originally proposed, would terminate, which is in the area of the lobster and crab habitat, is approximately one and one-half to two feet deep at mean low water. The dock as presently proposed would extend some 30 feet beyond that area, or about 160 feet from the waterward edge of the shoreline mangrove fringe, or 190 feet from the mean high water line. Thus, the dock as presently proposed would terminate in a flat or sandy area which is somewhat deeper or about two to two and one-half feet deep at mean low water. Termination of the dock at that point, with boat traffic involved with the dock beginning and ending at that point will result in less likelihood of damage to the lobster and crab and other more fragile marine life habitat which occurs landward of the 190 foot termination point. At this point, the dominant marine species are patchy growths of red algae (Laurencia sp.). These growths are less susceptible to damage from prop-wash and wakes of boats than are the more landward areas characterized by turtlegrass, Cuban shoalweed and the "hole and outcrop" nursery habitat area for fish, lobsters and stone crabs. The physical and biological characteristics of the water bottom at this 190 foot distance offshore are more compatible with boat usage. The bottom here is characterized by hard caprock close to the surface, with a shallow overlying layer of inorganic, coarse-grained sediment consisting primarily of pulverized rock. There are very little or no seagrasses at this point. The applicant's boat draws approximately 12 inches of water underway and 18 inches at rest, and the dock is for the private use of the applicant only. The water depth at the termination point of the dock effectively precludes the applicant from navigating to and from the proposed dock with a significantly larger, more powerful boat and thus the physical characteristics of the water depth and hard bottom existing at the dock site themselves effectively limit the likelihood of harmful prop scouring or boat grounding damage. Impacts on water quality caused by the installation and operation of the proposed dock to the extent of its use by the applicant's private boat only, will be minimal. Some turbidity and disruption of marine life will inevitably occur during construction, but this will have no serious impact on either water quality or marine resources. The dock, as it is proposed to be constructed, will be at least three feet above mean high water level. It will be sufficiently narrow in width so as to preclude significant shading of seagrasses from sunlight and resultant death or damage to the seagrass beds between the end of the dock and the mean high water line, such that no water quality violation or harm to these marine resources will ensue. The proposed construction will not eliminate valuable marine resources in Niles Channel and will have no immediate or long-term adverse impact on the quantity or quality of the State's natural marine resources through the loss of habitat in the Niles Channel area involved. Because of the varying amounts of wetlands encompassed in the lots in the Niles Channel subdivision, it is unlikely that all of the lots in the area will be developed, or that a great number of docks similar to the proposed dock will be constructed. The Petitioner's expert witness, Mr. Robertson, established that less than half of the lots in this subdivision are suitable for or likely to be developed. The Petitioner's own witness, Fahrer, also established that Monroe County is planning to restrict development in this area through their zoning power. Accordingly, there is no reasonable expectation that many similar docks will be constructed in the Niles Channel area. Further, the recent amendments to the DER's organic statutes and related rules which took effect on October 1, 1984 mandate consideration of additional restrictive criteria involving effects of such projects on wildlife habitat, which will further serve to restrict development along the shoreline in this area. The shoreline in this subdivision is essentially undeveloped, with only one other dock presently in place, which is longer and extends further into Niles Channel than does the proposed dock. Although there was testimony by witnesses for Petitioner that the proposed dock would entail bone fishermen having to navigate out and around the dock, this testimony does not establish the premise that the dock will pose a serious impediment to navigation. The proposed dock may add slightly to the disruption of some recreational fishing navigation, however, since the adjacent property has the longer dock already in place, any disruption caused by this proposed shorter dock will not be significant and will not be contrary to the public interest in terms of navigation impediment.
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 the State of Florida, Department of Environmental Regulation grant the application of Debra Flynn for a dock construction permit in accordance with the conditions delineated above.

MICHAEL RUFF Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 9th day of April, 1985.

Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant facts are found: On May 3, 1978, the petitioner filed with the respondent an application for dredge and fill permits and a water quality certificate to allow petitioner to complete its planned residential community on and adjacent to Marco Island, Florida. the petitioner expended in excess of $100,000.00 in preparing the permit application. The proposed project involves some 4,000 acres of development on approximately 17,000 acres of land owned by the petitioner. On November 28, 1979, after seeking and obtaining additional information from the petitioner, the respondent issued its notice of "intent to deny" the permit application. The Department claims jurisdiction over the proposed project pursuant to Chapter 253 and 403, Florida Statutes, and Section 17-4.28 and 17-4.29, Florida Administrative Code. The nine page "intent to deny" specifically cites Rule 1704.28(3), Florida Administrative Code, and concludes that state water quality standards will be violated. Beyond that regulatory citation, the "intent to deny" does not specify by rule number which of the water quality standards the Department feels would be violated by the proposed project. However, the "intent to deny" does conclude that the area proposed for development will include "approximately 1,500 acres of uplands and approximately 2,600 acres of waters of the State, submerged lands of waters of the State, and transition zone of submerged lands of waters of the State. In discussing the overall impact from the project as a whole, the respondent notes that the intertidal shoreline areas are utilized by wading birds and that the mangrove tidelines provide a vital habitat for fish and wildlife. In discussing the specific work areas, the respondent concludes that the destruction of the extensive freshwater marsh system would eliminate a significant habitat intensely utilized by a wide variety of birds. The "intent to deny" further concludes that the development of the proposed work area would be expected to violate state water quality standards for dissolved oxygen. The respondent's "intent to deny" is the subject of a pending administrative proceeding between these same parties in Case Numbers 79-2471 and 80-683. In those proceedings the petitioner is contesting, inter alia, the respondent's application of the rules under challenge in this proceeding. Although petitioner challenges other rules of the Department, the testimony adduced at the hearing concerned only those rules relating to water quality standards; to wit: Rules 17-3.05, 17-3.08(4) and 17-3.09(3). Dissolved oxygen concentrations are an important gauge of the existing quality of water and the ability of a water body to support a well-balanced aquatic animal life. A concentration of at least 5.0 parts per million (or milligrams per liter) is needed to support a well-balanced fish population, and a concentration of 4.0 mg/1 is about the lowest which will support a varied fish population. There are numerous natural factors which affect the concentration of dissolved oxygen in surface water bodies. Such factors include physical transfer between the water and the atmosphere (aeration), the limit of a water body's ability to absorb oxygen (saturation value), the amount of oxygen used to decompose dead material, photosynthesis of aquatic plants and the actual vertical location of the sampling. These factors are influenced by many variables, such as wind, temperature, stratification, salinity, the season of the year, the time of the day, rainfall, water clarity, mixing and flushing. The level of dissolved oxygen can vary significantly in the same body of water during one twenty-four hour period. A balance of dynamic, natural processes causes dissolved oxygen levels to vary extensively in different water bodies and within the same water body during different times of the day and during different seasons of the year. Some of the water bodies in the Marco Island area contain dissolved oxygen values below 4.0 parts per million (or milligrams per liter) during at least a portion of a twenty-four hour period. This is due to natural, as opposed to manmade, causes. A water body containing levels of dissolved oxygen less than 4.0 milligrams per liter does not necessarily indicate a discharge of contaminants into that water body. The parties have stipulated that the Final Order rendered by the Department of Environmental Regulation in the case of Capeletti Brothers, Inc. v. Dept. of Environmental Regulation, Case No. 79-1602R (July 7, 1980), accurately represents the Department's position with respect to its authority to consider wildlife and other biological factors in reviewing permit applications pursuant to Chapter 403, Florida Statutes.
Findings Of Fact The applicant currently operates a 58 slip marina Village at the proposed site, which was constructed under a modified permit from the Department in 1980 by Sunset Realty. Subsequent to that construction, the Petitioner commenced its Marina Village project on uplands adjacent to the existing dock facility and entered into a lease with Sunset Realty to operate the present marina as part of its "Boca Grande Club." The operative portion of the existing marina, that is, where boats are moored and operate, is in water eight feet or greater in depth. The marina provides fuel service at a separate fuel dock as well as electric and telephone service at the individual slips, thus permitting boats using the slips to hook up to on- shore electrical and telephone service. Sewage pump-out equipment is available at the fuel dock and a portable sewage pumping facility is available to be moved to each slip as necessary. Boca Grande Club employs a full time dock master who lives aboard a boat at the existing facility. The facility presently generally serves larger craft, that is, boats generally larger than 25 feet in length and serves some vessels in excess of 60 feet in length. The marina village portion of Boca Grande Club is a condominium, residential development, which is nearly completed and will consist of 48 residential units. A second portion of the Boca Grande Club is located on the Gulf of Mexico some 2,000 feet away from the marina village. The entire project employs slightly more than 100 people. The Petitioner contends that the existing marina of 58 slips is not sufficient to provide adequate dock space for the residents of the development, as well as members of Boca Grande Club. It also contends that the existing dock elevations are such as to make access from small boats to the dock difficult. The number of residents or club members requiring boat slips was not established, nor was it shown that efforts to modify existing dock elevations have been attempted unsuccessfully. In any event, the Petitioner applied to the Department on February 15, 1985, to construct the approximate 3450 square feet of additional dock facility. This would include a "T" shaped structure with an access ramp or walkway extending approximately 189 feet toward the existing channel from the shore. The waterward "T" portion will be 237 feet ~n length. Additionally,. an "L" shaped structure with two sections, each approximately 75 feet in length, would be constructed which would accommodate six boat slips. The "T" shaped dock will accommodate 19 boat slips at its waterward end. The docks proposed will contain ten 3' X 15' finger piers with regard to the "T" shaped dock and two 3' X 15' finger piers attached to the "L" shaped dock. The applicant would install 42 mooring pilings in the bottom of Gasparilla Sound for the mooring of boats using the docks. Thus, the applicant proposes the addition of approximately 25 boat slips with the proposed docks, all of which will be located within Gasparilla Sound, in the Charlotte Harbor Aquatic Preserve, an Outstanding Florida Water (OFW). This is a Class II water body pursuant to Chapter 17-3, Florida Administrative Code, and has also been designated an outstanding Florida water, pursuant to Rule 17-3.041, Florida Administrative Code. The docking facility will be located in an area vegetated by sea grass, including turtle grass and associated algae. The access ramp for the "T" dock would be through a mangrove fringe including red, white and black mangroves. The Department's appraisal recommended denial of the application unless certain modifications to the "T" shaped dock are accomplished, including omitting the "T" shaped docking structure or relocating it to an area without grass beds; that the pilings should be driven into place rather than placed in augured holes; that turbidity screens should be installed and staked around the proposed piling site and that no boats over 25 feet in length or equipped with heads or toilets should be allowed to moor at the docking facility, nor should boats be permitted with people living aboard them. On September 5, 1985, the Respondent issued its Intent to Deny indicating that the project was expected to violate water quality standards and that the construction of the dock and the presence of the moored boats attendant to use of the dock would lower existing water quality in terms of turbidity, biological integrity, bacteriological quality, especially as to fecal coliform and total coliform bacteria and based upon the DER's position that the "T" shaped dock would not clearly be in the public interest in several respects. The Department has no objection and proposes to issue a permit for construction of the smaller, "L" shaped dock. In response to the Intent to Deny, the Petitioner resurveyed the seagrasses in the area and located a site where the water depths sloped to deeper water and seagrasses were sparser. It modified its application, moving the waterward extension of the dock over the deeper water in the less dense seagrasses, but could not move the dock to a location to avoid seagrass since to do so would not allow maneuvering room for larger boats utilizing the existing dock. The applicant agreed to the other suggestions of modification by the Respondent. Thus, the applicant subsequently modified the application to include "bow-in" mooring of boats so as to place boat propellors over the deepest possible waters at the mooring site, as well as raising the central portion of the access ramp leading waterward from the shore, to provide for greater light penetration and less shading of seagrasses, as well as narrowing the dock to five feet in width where it passes through the mangrove fringe, so as to limit alteration of the mangroves at the site to only three trees. The Department continues to take the position that the permit should be denied, however, on the basis that the construction of the dock and the presence of the boats attendant to the dock will lower existing water quality in terms of the above particulars and based upon the DER's evaluation that the "T" shaped dock will not clearly be in the public interest. AMBIENT WATER QUALITY The Petitioner tendered C. W. Sheffield, professional engineer, and Dr. Martin Roessler as experts in the field of water quality and they were accepted without objection. The respondent tendered the expert testimony of Mr. Doug Frye and William Porter, respectively a dredge and fill specialist and supervisor and an environmental specialist with the Shellfish Monitoring Program for the Department of Natural Resources, who were accepted as expert witnesses in the areas of water quality and, with regard to Mr. Porter, the impacts of water quality on shellfish. It was thus established that the ambient water quality in the cove which contains the present marina and where the proposed docking facilities would be is generally good. The water meets all relevant State regulatory standards with the exception of fecal coliform and total coliform bacteriological standards for Class II waters. In that regard, repetitive samples have shown violations of the fecal coliform and total coliform bacteriological standards for Class II waters on a number of occasions. The data relied upon concerning fecal coliform organism levels at the project site was collected and analyzed over approximately a one year period during which time the samples were shown to contain fecal coliform and total coliform bacteria in violative concentrations a number of times. Marinas are known discharge sources for fecal coliform organisms. This is especially true of moored boats in marinas which often have toilets or heads which are illegally flushed into the State waters within the marina. The presence of moored boats with heads are known discharge sources of fecal coliform organisms and the boats utilizing the present marina and the proposed project do, and likely will, have toilets on board, which can be improperly discharged into the waters of the marina. This marina has been established to be a source of discharge of fecal coliform organisms in violation of the relevant standard for Class II waters of the State. There presently exists relatively high levels of fecal coliform organisms ranging up to 50 organisms per 100 milliliters of water in the area of the existing marina. This level of concentration exceeds the regulatory standard for fecal coliform bacteria in the Class II water quality rules. Although Mr. Porter discussed the possibility that high levels of coliform bacteria could be caused by birds or animals depositing fecal material in the water, he established that the likely source of elevated levels of this bacteria was improper operation of heads aboard boats, as pointed out by the fact that samples taken in other areas of the Gasparilla Sound away from marina sites do not exhibit the high coliform levels found on repeated occasions at the subject site. Thus, it has been established that the ambient water quality is within State standards for all parameters with the exception of fecal and total coliform bacteria for Class II waters. The Petitioner contends that Class III water standards are appropriately applied herein inasmuch as the Department placed the Class III standards rather than the Class II standards at issue in its Intent to Deny, albeit mistakenly. There is no question, however, that there are Class II waters of the State involved at this site and the subject area is within the aquatic preserve and outstanding Florida waters. The Petitioner is charged with knowledge of this inasmuch as the aquatic preserve boundaries are delimited in the Department's above-cited, published rule. In preparing and processing its application and electing to proceed with this project, the Petitioner is charged with knowledge that these are Class II waters and that the water quality criteria and considerations applicable to Class II outstanding Florida waters are the appropriate parameters with which it must comply. In any event, this is a de novo proceeding and the Department's initial position with regard to this application is not binding in favor of or to the prejudice of any party to the Section 120.57(1), Florida Statutes proceeding. IMPACT ON BENTHIC COMMUNITY ยท9. There is a moderate stand of seagrass at the proposed site of the "T" portion of the dock or waterward end of the dock, with dense seagrass beds existing toward the shore, over which the narrower walkway portion of the dock will traverse. Seagrass beds are an especially productive marine community which contribute greatly to the biological diversity in surrounding waters because of their important function in the marine food chain. That function is involved with the seagrasses production of detrital matter consisting of seeds and vegetative material which marine organisms feed upon and upon which organisms larger fish, including commercial and sport fish species, feed upon. Potential adverse impacts caused by a project of this type on the Benthic Community at the project site and especially the seagrass beds involve the potential shading of seagrasses caused by the location of the dock over them, as well as the mooring of boats over them which shading retards or eliminates photosynthesis, which ultimately can kill the seagrass and thus reduce marine productivity in the area. The concentration of boats at such a mooring site as the end of this "T" dock will concentrate the effects of prop scouring, washing and prop dredging, which will have a destructive effect on seagrasses as well as the settling out of sediment from propellor wash or disturbance of the bottom on the seagrasses which can ultimately smother them as well as other marine life forms. In discussing these considerations, it should be pointed out that the "T" portion of the dock would be oriented in a general north-south direction which causes the shadow of the dock to move rapidly as the sun passes overhead in a general east to west direction. This would tend to minimize the effect of shading on the seagrass of the dock itself, particularly with regard to the approach ramp portion of the dock which is relatively narrow. That portion of the dock extending toward the shore runs in an east to west direction and would not exhibit the same rapidly moving shadow, but the central portion of the approach walkway has been elevated to such an extent that light reaching under the dock from both sides will be sufficient to allow photosynthesis of the seagrasses under the dock, although not for as long a period of the day nor at the same rate as would be the case if the dock were not present. The Petitioner asserts that its voluntary relocation of the "T" shaped portion of the dock from an area of dense sea grass to a moderately populated sea grass bed plus the proposed bow-in mooring of boats so as to alleviate propellor damage to the seagrass, together with its view concerning the prevailing water depth at the end of the dock, will serve to prevent damage to the seagrass at the end of the "T" dock where the boats will be moored. It has been shown, however, that the mooring of boats whether bow-in or otherwise will still create a significant amount of shading of the bottom which, together with the shading caused by the "T" dock as well as the associated finger piers will retard or prevent photosynthesis to some extent, especially where boats are moored for days at a time without moving. This will significantly reduce the marine productivity attributable to the seagrass by retarding its natural function or, in some cases, killing it with the resultant loss of the detrital production as well as carbon production, the former being crucial to the proper functioning of the marine food chain in the area. If the seagrass is damaged or extinguished by the shading effect, prop scouring and washing, and/or settlement of turbidity on the seagrass, or a combination of these factors, not only will its productivity be lost, but the biological diversity of marine life in the area will be reduced as it relates to those vertebrate and invertebrate marine animals which depend on seagrass as a food source either directly or indirectly. Dr. Roessler, for the Petitioner, opined that the attached biological communities or "fouling" organisms such as barnacles which would form on the dock pilings, if they were installed, would provide habitat for marine life and invertebrates and thus enhance the biological diversity of the area. These fouling organisms which attach to pilings, however, represent a very narrow portion of the potential marine biological diversity of life forms in an area such as this. Their advent on the pilings, should the pilings be installed, would not mitigate for the loss of important marine habitat and resultant species diversity that elimination of this portion of the seagrass beds would pose. Thus, reasonable assurances have not been established that significant adverse impact to the Benthic Community in the form of damage or elimination of the seagrass beds and their dependent biota will not occur due to shading and propellor scouring, dredging and washing occasioned by the installation of the docking facility. Respondent's expert witnesses Sheftal, Barth, and Dentzau uniformly expressed a concern for propellor scarring, dredging and prop washing of the seagrass beds caused by an improper operation of boats in the project area where water is too shallow over the grass beds to protect them from the resultant propellor damage. In this regard, the Petitioner's own experiments with actual boats indicated that approximately one to 1 1/2 feet of water will remain between the bottom of the sound and the boat propellors at the end of the "T" dock for the general type and size of boats which will use the dock, even assuming that the boats are moored bow inward, thus taking maximum advantage of the deepest water possible under the propellors when a boat engine is started. Respondent's witness Dentzau performed a test with a 21 foot boat with an approximately 100 horsepower outboard engine running it in both forward and reverse at the "T" end of the dock. He was able to readily generate a "plume" of turbidity consisting of sand and other bottom material suspended in the water by the scouring action of the propellor. Although it was demonstrated for water quality parameter considerations that this turbidity plume did not violate the water quality standards for turbidity, it obviously shows that over time the turbidity suspended by boat propellors will settle on the seagrasses and other bottom dwelling biota to their detriment and, more immediately important, demonstrates that prop washing and scouring will occur by boats even if moored bow-in at the presently proposed site of the "T" shaped portion of the dock. The Petitioner proposes by the configuration of its "L" shaped dock in conjunction with the IT" shaped dock, as well as with buoy lines, to keep boat traffic away from the dense grass beds surrounding the proposed dock site and over which the walkway will extend. The Petitioner will mark the entrance channel to the marina itself to keep boats from straying over adjacent grass beds. It has not been demonstrated, however, what steps can be taken to effectively prevent boats from approaching the side of the proposed dock around the ends of the buoy lines and over the dense grass beds toward prohibitively shallow water where prop scouring and scarring will occur. Further, although the Petitioner will mark the entrance channel to the marina itself to keep boats from straying over adjacent dense grass beds, the likelihood of propellor damage to the grass beds in the vicinity of the end of the "T" dock has been exacerbated by the concentration of boat traffic which will result by installation of that dock, over waters at the mooring site which are of insufficient depth to protect the grass bed at that location from scouring and washing from boat propellors. In view of these reasons, significant adverse impacts to the Benthic Communities and especially to the grass beds themselves will result by installation of the docking facility at the site proposed, primarily because of insufficient water depth for safe operation of boats in relation to the well-being of the grass beds in the vicinity of the end of the dock and because of the shading which will result by installation of the "T" shaped portion of the dock in conjunction with the boats to be moored to it and the finger piers between the boat slips attached to it. WATER QUALITY The Respondent, through its water quality expert witness, Doug Frye, expressed the concern that the proposed project would violate Rule 17-3.051, Florida Administrative Code, which requires that the State's waters be free from pollutants above a certain level measured by various accepted and codified scientific methods of measurement. In this regard, the primary concern of the Department is bacteriological quality as well as turbidity resulting from boat operation. The turbidity standards contained in the above Rule provides that State waters not exceed 29 nephelometric turbidity units above the natural background level. The Respondent contends that this level will be exceeded as a result of operation of boats in the vicinity of the dock. The Petitioner, however, presented a soils analysis and silt settling study which showed that bottom materials in the area involved consist of sand, with some finely pulverized shell and that this material settles very rapidly after being disturbed with little silt remaining in suspension a significant period of time after the disturbance. This is primarily because the level of organics in the bottom substrate is very low at this site. In this connection, the Petitioner's expert witness, Mr. Sheffield, anchored a 16 foot boat with a 40 horsepower outboard motor in the docking area of the proposed project. He operated the boat at 1,000 RPM for an extended period of time while measuring the resultant turbidity. The results of his measurements showed turbidity to be in the range of 5-11 NTUs. The Respondent's witnesses, however, operated a larger 21 foot boat at the location of the "T" shaped portion of the dock maneuvering it back and forth with a fairly large outboard motor in the 100 horsepower class, which might be presumed to be typical of the boats which will be using the proposed facility. The maneuvering of the boat with the larger engine in this shallow water created a clearly visible plume of turbidity shown by photographs introduced into evidence by the Respondent. In fact, however, although the turbidity plume was clearly visible, the Respondent's own direct measurement of turbidity taken from within the plume immediately after it was generated was 23.8 NTUs, still below the State standards for violations as to turbidity. The existing marina facility has a fuel dock and has adopted a fuel spill contingency plan. There will be no fueling of boats nor fuel kept at the proposed docks. Nevertheless, marinas were established to be a known source of discharge of oils and greases and the presence of more boats utilizing all the dock facilities, especially during fueling and maintenance procedures, will result in additional oils and greases being deposited in the water. Even if there is no fueling facility planned for the proposed docks, the additional boats represented by the 25 additional slips sought to be approved will have to be fueled and likely at the existing facility. This will heighten the risk of fuel, oil and grease spills. In this regard, it must be remembered that the present marina and the proposed docking facilities are in outstanding Florida waters in which no degradation of ambient water quality is permitted. In this context then, the Petitioner/Applicant has, not provided reasonable assurances that pollution levels for oils and greases will not increase as a result of the potential addition of 25 boats to this marina facility. A substantial issue has been raised in this proceeding concerning water quality as it relates to the bacteriological standard. It has been established that this marina is presently a source of discharge of fecal coliform organisms which frequently are present in sufficient concentrations so as to violate the standard for that organism for Class II waters. Fecal coliform bacteria are accumulated in the bodies of shellfish. The shellfish themselves are not harmed, but contaminated shellfish can accumulate concentrations of as much as 100 times the ambient fecal coliform bacterial levels present in the waters they inhabit. Fecal coliform bacteria can cause extreme illness in human beings, sometimes even paralysis and death. Fecal coliform bacteria in State waters results from the deposition therein of human or animal waste. The Petitioner maintains a sewage pumpout station located at its fuel dock with a direct connection to its sanitary upland sewer system, as well as a portable sewage pump that can be moved to each boat slip for pumping out of toilets or "heads" on boats. Upland fish cleaning stations will additionally be provided with the proposed docks so as to prevent refuse from fish cleaning activities being deposited into the waters of the cove. The fact remains, however, that there presently exist high levels of fecal coliform organisms in the waters of the cove at the marina site, in the above noted violative concentrations on repetitive occasions. The presence of boats moored in the marina with "heads" aboard are a known discharge source of fecal coliform organisms. The Petitioner proposes to restrict boats using the facility to those boats without marine heads aboard or requiring those with heads to keep them locked or otherwise not discharge them into the waters of the marina. If boats utilizing the marina have toilets aboard, however, there is a substantial likelihood that at some point those toilets will be discharged into the waters of the cove before any of the Petitioner's monitoring personnel are aware of it. The problem is thus one of enforcement. In this regard, it is established that even with the sewage pumpout station and the portable sewage pumpout device, that there are a number of "live-aboard" boats with marine heads in the marina at the present time and customarily. This has caused the above found violations of fecal coliform, Class II water standards. Although the Petitioner proposes to restrict boats at the proposed docking facility to those less than 25 feet in length and to establish a monitoring program by the marina management personnel to assure that the boats with heads only contain heads approved by Coast Guard regulation, reasonable assurances have still not been established that the enforcement plan proposed can be effective in ensuring that no marine heads or other sources of coliform bacteria will be discharged into the waters of the cove at the project site. The plan proposed by the Petitioner simply did not ensure that boats having marine heads will not use the marina and that those persons using boats so equipped will not, on some occasions, discharge the heads into the waters of the marina at the project site nor that spills will not result in the sewage pumping-out process. The Respondent's expert witness, Mr. Porter, confirmed that most fishing boats of the open "center console" variety of 25 feet length or less do not contain marine heads, nevertheless, he established that in his experience monitoring marinas of this sort, the restrictions against marine heads of the non-approved variety and the attempted restriction against boats discharging the contents of their heads into the waters of the marina cannot be effectively enforced nor was it established that fishing boats without marine heads will be the only type of boat to use the proposed docking facilities. Accordingly, the waters of the cove at the marina site and project site are in frequent violation of the fecal coliform and total coliform parameter for Class II waters and reasonable assurances have not been provided that the fecal coliform bacterial levels will not increase as a result of the installation and operation of the proposed facility with its attendant boats. Because of the likelihood of shellfish contamination by fecal coliform bacterial levels which will likely increase if the proposed project is constructed and operated, together with the loss of marine habitat and productivity posed by the harm likely to result to the seagrass beds in the vicinity of the proposed facility due to attendant boat operation, it has been shown that the water quality parameter for biological integrity in these Outstanding Florida Waters will likely be degraded. The "Diversity Index" of marine microinvertebrates in the area of the affected seagrass beds will likely be reduced below 75 percent of background levels. Therefore, in the context discussed above, the proposed construction and operation of the 25-slip marina facility with the "T" dock will lower ambient water quality in these outstanding Florida waters and will result in violations of State water quality standards for Class II waters in the above particulars. SHELLFISH HARVESTING Mr. William Porter of the Department of Natural Resources Bureau of Shellfish Sanitation established that the cove where the project would be located is closed to the taking of shellfish as a result of the contamination or potential for contamination of shellfish by coliform bacteria contained in fecal material. His Department's water quality sampling confirmed the elevated levels of fecal coliform bacteria in the cove on repetitive occasions. This elevated level of coliform organisms was shown to result from improper operation of marine toilets upon vessels using the marina at the present time. Because of the potential for contamination from vessels discharging fecal material, Mr. Porter established that the Department would likely close an area 50 percent larger than the present shellfish harvest closure area as a result of a 50 percent increase in the number of boats capable of using the marina if the proposed project is built. Mr. Porter acknowledges that if it could be assured that boats using the marina did not contain heads, the increased area of closure might be lessened after this project were built. He also established as pointed out above that such restrictions on boats containing heads from using the proposed boat slip is very difficult to enforce. Even with the present central sewage pumpout facilities and portable pumpout equipment at the existing marina, the marina still has failed to comply with fecal and total coliform standards for Class II waters on a repetitive basis. The management of the present marina has allowed live-aboard boats at the marina even though it has posted warning signs against boat owners discharging toilets in the cove waters. Mr. Porter also acknowledged that the Boca Grande North Marina, owned by Gasparilla Pass, Inc., was recently permitted by the DER and constructed and has not yet resulted in the Department's closing an additional area to the taking of shellfish. The area the marina is situated in, however, is only "conditionally approved" for the taking of shellfish, meaning that it is subject to closer monitoring by the DNR with a view toward the possible necessity of closing waters in the area of that marina. It was not established, however, how the fecal coliform or total coliform levels in the waters adjacent to that marina compare to the existing marina or the site of the proposed docking facilities at the existing marina, nor what conditions might prevail which would render that other marina a comparable site to -be used as a relevant demonstration of what conditions might be expected at the present marina if the proposed project were built and operated. Thus it has been shown that even though the Petitioner proposes limiting the size of boats at the proposed facility and closely inspecting and regulating any marine heads on boats using the facility to make sure they comply with Coast Guard regulations, it has not been demonstrated that the additional deposition of fecal coliform bacteria in the waters often the cove will be adequately prevented by the proposed enforcement measures. It is thus reasonably likely that the construction of the proposed project will lead to the closing of an additional area of water which is presently approved for shellfish harvesting. The closure of shellfish harvesting in waters is contrary to the public interest in terms of recreational values, fishing and marine productivity and others of the seven public interest criteria quoted below. Further, the contamination of shellfish, which can cause severe illness or even death in human beings, is clearly contrary to the public interest and there is a substantial likelihood that shellfish contamination is already occurring in the area due to the characteristic of shellfish by which they accumulate or store fecal coliform organisms to reach injurious levels for human consumption even though the shellfish themselves appear to be healthy. The area of the proposed project is extensively used for commercial and recreational shellfish harvesting at the present time, outside the immediate closed waters of the marina within the cove. PUBLIC INTEREST Section 403.918(2) (a) (1-7) requires that the Petitioner provide reasonable assurances that the proposed project will be clearly in the public interest. The public interest considerations of those seven criteria concern whether the project will adversely affect public health, safety or welfare or property of others: whether it will adversely affect conservation of fish and wildlife or their habitats; whether it will adversely affect the fishing or recreational values or marine productivity in the project vicinity; whether it will be of a temporary or permanent nature; and the effect on the current condition and relative value of functions reformed by areas affected by the project. Although Petitioner's witness, Dr. Roessler, related that the attached fouling communities, such as barnacles, which would form on the proposed docks and pilings would increase the diversity of marine habitat available, that will not offset the loss of marine habitat occasioned by the increasingly detrimental effect imposed by the project and the operation of it on the seagrass beds, in the manner discussed above. The fouling communities expected by Dr. Roessler to occur on the pilings to be installed, will not provide, nor replace the value of, the detritus (seeds and leaves) produced by the seagrass which would be lost, which is an important food source for marine organisms in the upper portion of the food chain in the area, some of which organisms include fish and have a high recreational value and commercial value. The importance of detrital production by the seagrass beds outweigh the value of the addition of the fouling communities on the pilings. In fact, the total diversity of marine species actually might decline even though the fouling organisms would be added with the installation of the pilings, once the harmful effects on the seagrass beds begin to occur after installation and operation of the proposed facility and over the life of the marina. Thus, in this regard, the project is contrary to the public interest and certainly not clearly in the public interest. Additionally, there is a substantial likelihood that shellfish may be contaminated which, in turn, will have an adverse effect on the public health, safety and welfare. The harvesting of shellfish has a substantial recreational and commercial value and is an important aspect of the marine productivity in the vicinity of the project. The heightened coliform bacteria production caused by the resultant expansion of the marina will adversely affect fishing and recreational values and marine productivity and will degrade the current condition and relative values of the functions performed by the marine habitat in the vicinity of the proposed dock. Finally, there is no question that the project will be of a permanent nature. The various detrimental effects on the public interest consideration found herein are rendered more critical by the fact that there is no truly redeeming public purpose or use for this project. This will be essentially a private docking facility designed to serve the residents of the applicant's attendant real estate development. The upland development is a condominium development and the slips will be owned by the condominium owners and not open to the general public, although the Petitioner did make vague reference to an idea that some slips might be rented to members of the public. This was not established to be the case and, in any event, the primary purpose of the boat slips is to enhance the desirability of the upland development. Although the Petitioner emphasizes that the advent of the additional slips might help attract as much as $1,000,000 additional revenue to the Boca Grande area by assisting the applicant in hosting the Annual Tarpon Release Fishing Tournament, it is also true that any development in a coastal area will likely represent some economic benefit to that area, but there is also a substantial economic and recreational benefit to maintaining the outstanding Florida waters involved in an undegraded condition and maintaining the present Class II, approved shellfish harvesting area unimpaired. Thus, although the proposed docks might be used for sponsorship of the subject fishing tournament and it can be said that that would enhance fishing and recreational value to some extent, it was not established that the tournament will not occur and that the extra revenue and enhancement of fishing and recreational value it will generate will not occur in the Boca Grande area anyway. The potential detrimental effects of the proposed project, delineated above, will also decrease fishing and recreational value over many years and for the life of this project in terms of harm to the marine habitat occasioned by the constant deposition of oils, greases and fuel and coliform bacteria in the Class II waters involved, as well as the other detrimental aspects of the project discussed above. It has not been established that the economic benefits of the fishing tournament and the addition of the boat slips will not occur but for the installation of this proposed docking facility. Although it may help relieve a shortage of marina slips in the area, it was not shown that this is the only alternative to relief of that shortage. ALTERATION OF MANGROVES The original site for the access ramp or walkway to the "T" shaped portion of the dock was selected through an on site inspection conducted in part by Respondent's witness, Andrew Barth. The mangrove area is less dense at the site of the walkway's penetration of the mangrove belt than surrounding mangrove areas. Petitioner's witness, Dr. Roessler, has participated in many studies involving mangroves in South Florida. He identified each tree within the proposed dock pathway. Through narrowing of the dock walkway to five feet and the relocation agreed upon by the Petitioner and Mr. Barth, it has been established that only three mangrove trees will be removed by the construction of the dock. Thus, there will be no substantial alteration or degradation of the mangrove fringe area at the project site. DOCK CONSTRUCTION Mr. C. W. Sheffield was accepted as an expert witness in the field of marine engineering. He established that the pilings will be installed using a 6 to 8 inch chisel point driven into the bottom of the sound with an air hammer. There will be no augering or other means of excavation used which would generate a substantial amount of turbidity. The air hammer will result in compaction of sediments by forces radiating out from the piling as it is driven, with the counteracting sheer force caused by the piling installation causing a slight bulging in the bottom around each piling, but nothing more. There will be no significant movement of sediment in the water column. The construction of the dock will take place moving from the land waterward, utilizing equipment mounted on the dock. Thus, construction barges will not be required to come into the shallow grass bed area with the potential for its damage. Small barges would be used in the deeper waterward portions of the project to install the mooring pilings off-shore from the end of the "T" dock. Turbidity curtains will be used during all construction, surrounding all phases of the construction work. In Mr. Sheffield's experience, such measures have resulted in no violation of the State turbidity standards at other similar projects, and are not likely to with this one. CUMULATIVE IMPACT A number of permits have been issued by the Department for docking facilities to the north of this proposal and other facilities are already in existence. Dr. Roessler opined that the geographic location of these, as well as that of this project, in light of the numerous inlets and high degree of tidal flushing and exchange through the inlets, will not result in any adverse cumulative impact occasioned by the addition of the proposed dock with 25 slips to those already existing in the Sound. It is noteworthy that, with regard to the potential this project poses for damage to the seagrass beds and for heightened production of fecal coliform bacteria, with the environmental damage attendant thereto, no proof was offered by either party concerning those considerations or effects to the extent that they might or might not exist at other marinas or docking facilities in the Gasparilla Sound area. There has been no proof to establish any cumulative impact.
