Findings Of Fact As planned, Phase I of Foxwood Lake Estates will consist of 300 mobile homes, which would require treatment of up to 45,000 gallons of sewage per day. The proposed sewage treatment plant would have a capacity of 46,000 gallons per day and would be capable of expansion. It would discharge treated, chlorinated water into a completely clay-lined polishing pond that has been designed for the whole of Foxwood Lake Estates at build-out; capacity of the polishing pond would be three times the capacity necessary for Phase I by itself. From the polishing pond, water is to flow into one or both of two evaporation-percolation ponds, either of which would be big enough for all the sewage expected from Phase I. The sides of these ponds would be lined with clay and a clay plug would constitute the core of the dike on the downslope side of each pond. According to the uncontroverted evidence, effluent leaving the treatment plant for the polishing pond would have been effectively treated by the latest technology and would already have been sufficiently purified to meet the applicable DER water quality requirements. The applicant proposes to dig the triangular polishing pond in the northwest corner of the Foxwood Lake Estates property, some 400 feet east of the western property line. The evaporation-percolation ponds would lie adjacent to the polishing pond along an axis running northwest to southeast. Their bottoms would be at an elevation of 164.5 feet above mean sea level and they are designed to be three feet deep. The evaporation-percolation ponds would lie some 300 feet east of the western property line at their northerly end and some 400 feet east of the western property line at their southerly end. A berm eight feet wide along the northern edge of the northern evaporation-percolation pond would be 50 feet from the northern boundary of the applicant's property. Forrest Sawyer owns the property directly north of the site proposed for the evaporation-percolation ponds. He has a house within 210 feet of the proposed sewage treatment complex, a well by his house, and another well some 300 feet away next to a barn. Two or three acres in the southwest corner of the Sawyer property are downhill from the site proposed for the ponds. This low area, which extends onto the applicant's property, is extremely wet in times of normal rainfall. Together with his brother and his sister, Charles C. Krug owns 40 acres abutting the applicant's property to the west; their father acquired the property in 1926. They have a shallow well some 100 feet from the applicant's western property boundary, and farm part of the hill that slopes downward southwesterly from high ground on the applicant's property. Sweetgum and bayhead trees in the area are also a money crop. Charles C. Krug, whose chief source of income is from his work as an employee of the telephone company, remembers water emerging from this sloping ground in wet weather. Borings were done in two places near the site proposed for the ponds. An augur boring to a depth of six feet did not hit water. The other soil boring revealed that the water table was 8.8 feet below the ground at that point. The topsoil in the vicinity is a fine, dark gray sand about six inches deep. Below the topsoil lies a layer of fine, yellow-tan sand about 30 inches thick. A layer of coarser sand about a foot thick lies underneath the yellow-tan sand. Beginning four or five feet below the surface, the coarser sand becomes clayey and is mixed with traces of cemented sand. Clayey sand with traces of cemented sand is permeable but water percolates more slowly through this mixture than through the soils above it. The applicant caused a percolation test to be performed in the area proposed for the ponds. A PVC pipe six feet long and eight inches in diameter was driven into the ground to the depth proposed for the evaporation-percolation ponds and 50 gallons of water were poured down the pipe. This procedure was repeated on 14 consecutive days except that, after a few days, the pipe took only 36 gallons, which completely drained into the soil overnight. There was some rain during this 14-day period. Extrapolating from the area of the pipe's cross-section, Vincent Pickett, an engineer retained by the applicant, testified that the percolation rate of the soils was on the order of 103 gallons per square foot per day, as compared to the design assumption for the ponds of 1.83 or 1.87 gallons per square foot per day. Water percolating down through the bottoms of the evaporation- percolation ponds would travel in a southwesterly direction until it mixed with the groundwater under the applicant's property. It is unlikely that the ponds would overflow their berms even under hurricane conditions. Under wet conditions, however, the groundwater table may rise so that water crops out of the hillside higher up than normal. The proposed placement of the ponds makes such outcropping more likely, but it is impossible to quantify this enhanced likelihood in the absence of more precise information about, among other things, the configuration of the groundwater table.
Recommendation Upon consideration of the foregoing, it is RECOMMENDED: That DER grant the application on the conditions specified in its notice of intent to issue the same.

The Issue The issue presented here concerns the entitlement of the Petitioner, Turtle Lake Land Trust, to be permitted by the Respondent, State of Florida, Department of Environmental Regulation, to dredge approximately 600,000 cubic yards of material in the area known as Turtle Lake, which is located near Jackson street and Fairfield Drive, Pensacola, Florida. The purpose of this project is to create a manmade lake. The dredged material world be placed on the lake shore.
Findings Of Fact On May 9, 1979, the Respondent, State of Florida, Department of Environmental Regulation, received an environmental permit application from the Petitioner, Turtle Lake Land Trust. The details of that permit application were contained in a form provided by the Department together with attachments to that form. A copy of this permit application may be found as the Respondent's Exhibit No. 2 admitted into evidence. By this application, Turtle Lake requested that it be allowed to dredge approximately 600,000 cubic yards of material in an area known as Turtle Lake, which is located near Jackson Street and Fairfield Drive, Pensacola, Florida. The purpose of the excavation was to establish a manmade lake approximately twelve (12) feet in depth in an area which is a cypress swamp and subject to periodic inundation by water. The materials removed from the dredging would be deposited on the shores of the lake, effectively raising the ground elevation at lakeside. The dredging would intersect the groundwater on the project site. The project is part of an overall development which would involve construction of residential housing and commercial facilities in the vicinity of the lake, with the lake to be used for fishing, sailing and other water recreation. The proposal of the Petitioner was reviewed by the Department and certain timely additional requests were made from the Department to the applicant to provide information necessary to evaluate the request for permit. The exhibits dealing with the request for additional information and responses to those requests may be found as Respondent's Exhibits 3, 5, 8, 9, 10 and 11 admitted into evidence. The Department solicited comments from the Florida Game and Freshwater Fish Commission on this subject and the comments were provided by correspondence from the Executive Director of the Commission. These comments may be found in Respondent's Exhibit No. 6 admitted into evidence, which is a copy of those remarks. The Department of Environmental Regulation, in keeping with the provision Subsection 253.124(3), Florida Statutes, performed a biological survey of the project site and submitted it to the Board of County Commissioners of Escambia County, Florida, for the Board's action. A copy of the survey may be found as Respondent's Exhibit No. 7 admitted into evidence. The Escambia County Board of County Commissioners, by Resolution dated October 11, 1979, approved the project subject to action by the Respondent and the United States Corps of Engineers. A copy of this Resolution may be found as the Respondent's Exhibit No. 12 admitted into evidence. Upon consideration of the permit request, the Department of Environmental Regulation notified the applicant of its intent to deny the permit request. This Letter of Intent to Deny was issued on January 31, 1980, and a copy of it may be found as Respondent's Exhibit No. 13 admitted into evidence. This matter has been presented for consideration before the State of Florida, Division of Administrative Hearings, upon referral by the Respondent of the original Petition and has been heard after opportunity for and amendment to that Petition. The hearing was conducted on September 23, 1980, as scheduled, in keeping with the provisions of Subsection 120.57(1), Florida Statutes. The project site is located in a cypress swamp which has also been referred to as a cypress head. The southern boundary of the project site east of Fairfield Drive has an impoundment area which is fringed by pine trees and other upland species, to include gallberry, southern brackin, blackberry and oak. There is within this area aquatic vegetation dominated by Eleocharis sp. and fragrant waterlily (nymphaea odorata). The cypress head itself, which is bounded on the west by Fairfield Drive, consists of cypress, blackgum, sweetbay and cinnamon fern, fragrant waterlily and pickerel weed (pontederia lanceolata). Within the zone of the cypress head standing water may be found, the dimensions and depths of which were not established at the hearing in sufficient detail to allow further comment in these findings. Fairfield Drive serves to contain the water found in the Turtle Lake swamp on the eastern side of that roadway; however, there is an exit from the cypress head under Fairfield Drive by a series of three 24-inch culverts which connect the manmade ditches. These ditches flow into Bayou Marcus and Bayou Marcus Creek and eventually into Perdido Bay. This water connection is a direct connection and Bayou Marcus, Bayou Marcus Creek and Perdido Bay are waters of the State. Immediately adjacent to Fairfield Drive east of that roadway in the vicinity the culverts water may be found standing and could be navigated and this may be seen by Respondent's Composite Exhibit No. 14. This water which although subject to navigation wad not identified sufficiently at the hearing to establish its length and breadth. The depth was two to three feet. This water adjacent to Fairfield Drive is not within that area of the proposed excavation. At present, the storm water runoff from the Forte subdivision located to the north and east of the project site, enters the cypress head swamp and at times of periodic inundation, this storm water runoff arrives at the area of the culverts into the ditch system and into Bayou Marcus, Bayou Marcus Creek and Perdido Bay. The oils and greases, fertilizers, pesticides, nutrients and other forms of pollutants which make up the storm water constituents are somewhat filtered by the cypress head swamp as it now exists, prior to the entry of those materials into the culvert area adjacent to Fairfield Drive and from there into the transport mechanism constituted of the ditches, bayou, creek and bay. If the project is built out, the dredging will remove those flora mentioned herein and the fauna which inhabit this swamp and will remove the cypress head from future use by the fauna which normally inhabit this form of environment. It would also take away the natural filtration to be provided by the swamp in the way of removing undesirable storm water constituents from the residential runoff in Forte subdivision and the proposed development associated with the lake construction. The removal of the swamp would destroy the capacity to convert raw nutrients into usable sources of food for indigenous dawn stream organisms. As can be seen in the Petitioner's Exhibit No. 1, the existing water table at the site is approximately 23 feet and ordinary highwater elevation has been measured at 24 feet with an existing grade of 21 feet. If the lake were excavated, the lake would show a water table with an elevation of 20 feet. The berm or dykes around the lake would have an elevation of 24 feet. Storm water from the current subdivision and the residential and commercial build-out associated with the project in question would be carried through underground storm water piping into four holding areas which have been referred to by the applicant as drainage corridors and retention area. These areas are separated from the lake by siltation screens and will serve the function of filtering out some storm water constituents which are solid particulates. The constituents which have been dissolved will flow through the siltation screen devices and into the lake proper. When the lake rises to a depth of 23 feet, the excess water will he transported through a proposed ditch into the area of the three culverts under Fairfield Drive and via those manmade conveyances into Bayou Marcus, Bayou Marcus Creek and Perdido Bay. Those storm water constituents such as oils and greases, fertilizers, pesticides, nutrients and other forms of pollutants which have not settled or been filtered will be transported through this system and deposited into waters of the State. In this connection, the drainage corridor and retention areas are not designed for long-term retention; they are primarily for short-term detention, depending on the amount of loading from the storm water runoff. The only pre-treatment associated with the storm water runoff is that filtration that occurs in the drainage corridor and retention area. (There was some discussion of possible gravel filters in conjunction with the drainage corridor and retention area but they were not part of the plan submitted to the Department in the process of project review.) In addition to the introduction of the storm water contaminants into the waters adjacent to Fairfield Drive at the area of the culverts and the bayou, creek and bay, these contaminants will be introduced into the ground water in the lake proper Although some increase in retention of storm water runoff may be expected, if the project were built, there would be a significant increase in the introduction of dissolved contaminants into waters over which the Respondent has jurisdiction, i.e., Bayou Marcus, Bayou Marcus Creek and Perdido Bay. Increases in these areas will occur in biochemical oxygen demand and undesirable nutrient and dissolved oxygen levels will decrease if this project is constructed. In association with this change, an increase in nuisance species would occur. The Petitioner has failed to do any background sampling to establish the natural background levels of the aforementioned conditions in waters of the State in order to identify whether water quality in the receiving waters would be degraded from existing conditions to the extent of violating the Department's water quality criteria.
Recommendation Based upon a full consideration of the facts as presented and the Conclusions of Law reached in this matter, it is RECOMMENDED that the Secretary of the State of Florida, Department of Environmental Regulation, deny the Petitioner a dredge and fill permit pursuant to Rule 17-4.28, Florida Administrative Code; a construction, operating and maintenance permit pursuant to Section 403.087, Florida Statutes; a ground water permit in accordance with Rules 17-3.071, Florida Administrative Code, and 17- 4.245, Florida Administrative Code; and be it further RECOMMENDED that the Secretary take no further action to require a permit(s) as might be indicated in keeping with Chapter 253, Florida statutes. 1/ DONE AND ENTERED this 22nd day of October, 1980, in Tallahassee, Florida. CHARLES C. ADAMS Hearing Officer Division of Administrative Hearings The Collins Building Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 22nd day of October, 1980.
Findings Of Fact The Petitioner owns property which fronts on Lake Serena in Putnam County, Florida. Petitioner has submitted an application to the Respondent to dredge an area waterward of the ordinary high water line of Lake Serena and to place the dredged material on another area waterward of the ordinary high water line. Approximately 13,000 square feet of surface area presently dominated by wetlands vegetation would be removed by the dredging activity. The Petitioner proposes to cover the area where the fill is deposited with white sand. Petitioner proposes to use the area as a sandy swimming beach. During the summer of 1976 the Petitioner commenced work on his proposed project without receiving a permit from the Respondent. The Respondent, through its agents, stopped the work, and this permit application proceeding ensued. Lake Serena is a relatively pollution-free lake. Most of the littoral or transitional zone Vegetation surrounding the lake has been replaced by sandy swimming beaches. Only approximately forty percent of the shoreline is an aquatic vegetated littoral zone. Aquatic vegetation in the littoral zone surrounding the lake serves an important and natural function in preserving the water quality of the lake, and the natural resources of the lake including fish and wildlife. The aquatic vegetation serves to filter runoff from uplands areas by assimilating nutrients that are in the runoff. Lake Serena is an oligotrophic lake. It is relatively low in nutrients. Aquatic vegetation in the littoral zone serves in part to maintain this condition. If the condition is not maintained the buildup of nutrients would cause an algae bloom, or buildup of algae plants on top of the lake. A buildup of algae on the lake would drastically decrease the oxygen levels of the lake. The algae itself uses oxygen. The algae also kills oxygen producing plants which thrive on the bottom of the lake because the algae cuts off light to these plants. As the algae dies, it sinks and decomposes and uses up more oxygen. An algae bloom of this sort, and the resulting diminishing of oxygen levels in the lake would constitute pollution. Removal of aquatic plants in the lake's littoral zone will also serve to diminish fish populations in the lake. Small fish use such an area as a nursery ground where they can hide from larger predators. The action of aquatic plants on nutrients also serves as an initial step in the food chain for fish. The littoral zone which the Petitioner proposes to dredge and fill is apparently not in its natural state. There was no direct testimony respecting past dredging activity, but there was hearsay testimony to the effect that a previous land owner had dredged what amounts to a sand bar to serve as a boat slip. The entire area is now dominated by aquatic vegetation. It is a viable part of the littoral zone of the lake, and serves the beneficial purposes set out in Paragraph 2 above. There was no evidence offered at the hearing from which it could be determined with any degree of certainty that the Petitioner's proposed project would have any finitely measurable impact upon water quality or wildlife resources in Lake Serena. Removal of all such littoral zones would, however, drastically change the ecology of the lake, and render it polluted. Sixty percent of the lake's shoreline has already been denuded of vegetation. Although it cannot be determined how much more such action the lake will tolerate, it is clear that there is a limit. If the Petitioner's project were granted, other similar projects would also be justified. Inevitably the lake's oligotrophic nature would be destroyed. While it cannot be concluded from the evidence that the Petitioner's project would have any precisely measurable effect upon water quality and upon the natural resources of Lake Serena, it can be determined that the only effect the project could have would be negative. Petitioner has not established that the project would not have an adverse impact upon water quality and natural resources of Lake Serena. Petitioner has apparently concluded that there is no other means for him to have a swimming beach on his property than through the project as he has proposed it. Other witnesses testified, however, that his property includes a site for a swimming beach on land that is not dominated by aquatic vegetation.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is, RECOMMENDED: That a final order be entered denying the Petitioner's application for dredge and fill permit. RECOMMENDED this 8th day of April, 1977 in Tallahassee, Florida. G. STEVEN PFEIFFER, Hearing Officer Division of Administrative Hearings Room 530, Carlton Building Tallahassee, Florida 32304 (904) 488-9675 COPIES FURNISHED: John Mussoline, Esquire CLARK & MUSSOLINE 501 St. Johns Avenue Palatka, Florida 32077 Vance W. Kidder, Esquire Department of Environmental Regulation 2562 Executive Center Circle East Montgomery Building Tallahassee, Florida 32301 Mr. Jay Landers, Secretary Department of Environmental Regulation 2562 Executive Center Circle East Montgomery Building Tallahassee, Florida 32301
Findings Of Fact The Petitioner is the owner of five acres of undeveloped real property in Henderson Creek Basin, Naples, Collier County, Florida. The property is dominated at the tree canopy level by medium-sized cypress. The mid-story plant association is made up of a varying mix of wax myrtle, dahoon holly, seedling cypress, and a lesser amount of slash pine. Hypercium, stillingia, poverty grass, and xyris are the major components of the ground cover. In the vicinity of the proposed homesite, the ordinary mean water depth averages 2-4 inches, as indicated by the water marks on the stems of cypress, stillingia, and cypress knees. Based upon the dominant vegetation, the project site is within the jurisdiction of the Respondent for the regulatory purposes set forth by law. The Petitioner intends to build a house on the property for his personal use. In order to construct the residence, the Petitioner applied to the Respondent for a dredge an fill permit. In the application,, the Petitioner seeks a permit which would allow him to place 1,200 cubic yards of sand fill over a .17 acre area of the submerged land. The proposed location for the housepad, septic tank and drainfield is the center of the five acre parcel. This is the predominant area in which the Petitioner seeks to place the fill. A large portion of this part of the property is low and consists of wetlands. The project, as it is designed in the permit application, does not provide the Respondent with reasonable assurance that the applicable water quality standards for the geographical area will continue to be met. In fact, the proposal demonstrates that a violation of the standards will occur. The Petitioner recently cleared 14,340 square feet of the wetlands in the proposed homesite area. The cypress trees which ware removed acted as a pollution filtration system and aided in the cleansing of the standing waters on site. These waters eventually percolate down to the aquifer to become an important source of fresh water for the state. Without the trees, the water will lose an important aid in the natural purification process. In addition to the adverse impact on water quality, the project will interrupt the natural water flow and filtration which has historically occurred when the water located in the low wetland area on the property has overflowed and eventually run into Henderson Creek. The Respondent is required to consider this natural condition in its determination as to whether or not a permit should be issued. The Respondent has indicated that certain changes should be made to the project in order to make it eligible to receive a permit. The Respondent suggested that the Petitioner relocate the fill area for the house pad eighty- five feet to the west of the proposed site. The septic tank and drainfield should be moved one hundred and ten feet to the west. The drive should be reduced to a single lane which leads directly to the housepad. In addition, three culverts should be placed under the drive. The purpose of these modifications would be to minimize the impact of the project on the wetland site. The movement of the project away from the cypress area would minimize the damage to water quality that would occur if the septic system were placed in the wetlands. If the design for the lane and driveway were modified, the harm to the natural sheet flow of the water through the area on its route to the creek would be greatly reduced. Another suggested modification was to remove exotic vegetation which has been planted or which has begun to dominate in some areas because of the clearing of the property which took place before and after the Petitioner purchased the property. The Respondent also seeks a construction plan from the Petitioner which demonstrates that the fill areas will be adequately stabilized and that turbidity will be controlled during construction. The final modification suggested by the Respondent was for the Petitioner to place a deed restriction on the property which would protect the planting areas and the remainder of the wetlands on the site. The Petitioner's expert, Gary L. Beardsley, has recommended that the proposed circular entrance driveway be eliminated and that a single and straightened lane be substituted its place. He further recommended that one 12" diameter culvert should be installed under the lane near the housepad in order to facilitate or equalize any sheet flow on the downstream side. This recommendation is made to substitute for the agency's proposal that three culverts be placed under the straightened lane. In addition, the Petitioner's expert recommended that the septic drainfield be moved 30 feet westward to reduce the fill slope requirements by abutting the house and septic fill pads. The Petitioner should also be required to replant 5,265 square feet of wetland area that he cleared on site with the approval of the Collier Natural Resource Management Department, but without the approval of the Respondent. The Petitioner has not agreed to any of the proposed modifications, including those proposed by his own expert. The Respondent's request for a deed restriction is not necessary to the agency's regulatory function. There was no reason for the request presented at hearing by the agency.
Findings Of Fact Background Respondent Telese is the owner and developer of Egret Woods Subdivision on real property contiguous to state waters in Pinellas County, Florida. The property is near the incorporated areas of Indian Shores and Largo. A residential subdivision borders the project locale to the east, and tidal mangrove swamps fringe the property to the west. An intracoastal connecting waterway known as the "Narrows" lies to the west of the swamps. These state waters connect Boca Ceiga Bay and Clearwater Harbor. The proposed subdivision area is an upland strip between the existing subdivision and the tidal swamp adjacent to the "Narrows". The uplands are predominantly vegetated by live oak, saw palmettos and slash pines. In order to develop the property, and to reconfigure lots from a previously platted subdivision, Respondent Telese applied for a permit from DER to fill 0.12 acres of DER jurisdictional wetlands located at the development site. The application for the permit represents that 340 cubic yards of clean, non-deleterious sandy loam is needed to fill disturbed high marsh areas and other low areas on the proposed lots. Respondent Telese has also requested permission to install culverts in the two conveyance/mosquito ditches that run through the lots before they reach their discharge points outside of the proposed lot lines. The Petitioners are owners of single-family homes within the subdivision to the east known as Whispering Pines Forest, 5th Addition. These property owners filed a Petition in which they disputed the appropriateness of the Notice of Intent to Issue filed by DER on August 21, 1990. In support of their position, the Petitioners identified a number of areas of controversy they contend should cause DER to reverse its preliminary decision to grant the "dredge and fill" permit on this project. Elimination of Natural Drainage The first area of controversy is the Petitioners' contention that their interests are substantially effected by the elimination of natural drainage from their subdivision into the uplands referred to as Egret Woods Subdivision. The entire area was owned by the same developer prior to the creation of Whispering Pines Forest 5th Addition. Essentially, the Petitioners allege that a subservient estate was created on these adjacent lands for their surface water drainage purposes which the proposed development eliminates. A review of the Notice of Intent to Issue reveals that culverts are to be placed in two of the open conveyance ditches currently transporting surface water runoff from Whispering Pines Forest 5th Addition through the uplands of Egret Woods into the wetlands. While this proposed change in the means of conveyance of the surface water may not affect the volume of water conveyed, it could adversely effect the quality of the water at the discharge points into the wetlands. At hearing, the Petitioners were unable to clearly articulate their concerns about this water quality issue. However, it is intricately interwoven into the surface water management issues. The water quality concern was obliquely referred to in the Biological and Water Quality Assessment Report where DER's application appraiser commented that the proposed conservation easements and the mitigation plantings, which replace the high marsh removed for lot reconfiguration, are sufficient to offset the potential adverse impacts of the requested fill and culvert changes to the existing water quality at the project site. Although this particular water quality issue was properly addressed by DER in its review of the permit application, it was not clearly set forth in the Notice of Intent to Issue. There is no way for a person whose substantial interests are affected by the proposed permitting decision to determine that DER had considered mitigation measures to prevent this adverse effect. A decrease in surface water quality would have been caused by the marsh elimination and the placement of culverts if the marsh had not been replanted, and other mitigative measures had not occurred at the locale. The Petitioners properly requested a formal administrative hearing to address surface water management issues as DER's consideration of the matter was not made clear to them in the Notice of Intent to Issue. The written report that discusses water quality as it relates to the mitigation plan was provided to Petitioner's post-hearing, after a copy of the written appraisal was sent to the Hearing Officer and all parties by DER. Planned Roadway The second area of controversy is the Petitioner's concern about the effects of the planned roadway on their properties. As the planned roadway involves the county, it is not a matter considered in the dredge and fill permit. Neither DER nor the Hearing Officer has subject matter jurisdiction. The Petitioners did not pursue this area of controversy or the road location at hearing based upon the Hearing Officer's ruling that it was not relevant to this permit review. High Water Mark and the Setting of the DER Jurisdictional Line The third area of controversy raised by Petitioners involves their collective concern about a variance in the height of the Mean High Water Line on the property on different documents presented to different agencies. The current survey for DER completed by the surveyor shows the Mean High Water Line at 1.16, while the survey submitted to Pinellas County in 1981 from the same surveyor reads the Mean High Water Line at 1.25. This was explained at hearing by the surveyor. It was his opinion as a professional surveyor that there is no basic difference between these two mean high water lines. Since the survey to the county in 1981, the Mean High Water Line has varied between 3 - 3 1/2 feet in some areas. The same methodology and simple mathematical formula was used by him during the two different surveys which were about eight years apart. The difference in the two surveys is within the tolerance level accepted within the industry and needs no further reconciliation. As a correlative issue, Petitioners raise a concern about the change in DER's jurisdictional line on various documents involving this same site over a number of years. DER's jurisdictional lines have changed since the "Hendersons Wetland Act" enacted on October 1, 1984. The jurisdictional line as depicted on this permit application was established by dominant plant species as defined in Rule 17-301.400, Florida Administrative Code, just prior to the application submission. This was the correct way to determine jurisdiction on the property at this particular point in time. Although the mean high water line may have been determinative of DER's jurisdiction on earlier permits, only the current law applies to the facts of this case. DER reviewed the jurisdictional lines as depicted on the property by Respondent Telese's consultant and found them to be properly placed during the processing of the permit application. Historical DER jurisdictional lines and permit reviews are irrelevant to this permit review as it is based upon the agency's current rules the applicable statutory criteria, and current site conditions. Fill Calculations The fourth area of controversy involves the Respondent's request to place fill on the site. When Petitioners used an engineer's scale to measure the areas to be filled on the permit drawings, their volume calculations reveal that more fill will be needed than represented on the permit application. Petitioners are concerned that this error could cause DER to approve a permit which does not accurately depict site conditions. The actual fill calculations were done by the professional engineer with a computer model based upon average elevations, depth and area. In his professional engineering opinion, his calculations were accurate, which was given great weight by the Hearing Officer. The drawings used by the Petitioners to calculate the required fill for the area were pictorial communications of what the Respondent Telese intended to accomplish at the site. These drawings were designed for descriptive purposes only and were not scaled to the extent that they could be accurately used for fill calculations in the manner applied by Petitioners. The computer modeling used by the professional engineer was the more prudent approach to the on-site fill requirements. De Novo Permit Review Although the wetlands resource permit requested by Respondent Telese is commonly referred to as a "dredge and fill" permit, there is no dredging associated with the project. The proposed placement of fill in the high marsh area of tidal wetlands on the property and the culvert placement requires construction activity in Class III Waters. Water quality impacts to the area will be a short term problem as water turbidity should take place only during construction. Specific conditions regarding construction techniques have been placed in the permit as permit conditions to minimize the impacts. There is no factual dispute as to whether the proposed conservation easement, the replacement and enlargement of the high marsh in another location, the removal of exotics such as Brazilian Pepper trees, and the planting of black mangroves will sufficiently mitigate the adverse impacts on water quality and the public interests at the proposed development. Without the replacement of the disturbed high marsh with high marsh plantings at a 1.91:1 ratio, the enhancement of the property through exotic removal, and the conservation easements at a 132:1 ratio, the Respondent Telese is unable to provide reasonable assurances that the project is not contrary to the public interest under the statutory criteria established in Section 403.918, Florida Statutes. The proposed project will not adversely affect the public health, safety, or welfare or the property of others. The flooding anticipated by the Petitioners is speculative, and has not been directly related to the fill placement and the culverts in the two conveyance/mosquito ditches. Conservation of fish and wildlife and their habitats, will not be adversely affected due to the high marsh replacement and the fact that the area provided only marginal wetland habitat prior to the permit application due to the invasion of exotics at the site. Any impact from the proposed project on this public interest criterion is offset by the mitigation plan. The project will not adversely affect fishing or recreational values or marine productivity in the vicinity of the project. The proposed plantings of black mangroves and the removal of exotics, along with the new high marsh swamp should enhance the productivity of the area. No future projects of a similar nature can be developed at this locale due to the conservation easements the Respondent Telese has consented to provide over the remaining undeveloped property owned by him in the area. These easements will allow the Department to limit and control activities that may be undertaken in these tidal waters to prevent degradation of the site from an environmental standpoint. The mitigation planting schedule provides reasonable assurances that water quality standards will not be violated in the area as a result of culvert placement in the two conveyance/mosquito ditches that transport surface water to Class III waters of the state. Balancing of Interests In the "dredge and fill" permit application appraisal, site review, and Notice of Intent to Issue, DER considered and balanced all of the required statutory criteria to determine that the project is not contrary to the public interest or applicable water quality standards. Area of Controversy All of the areas of controversy raised by the Petitioners which are within the Division of Administrative Hearings' jurisdiction, have been sufficiently met by the reasonable assurances of Respondent Telese and the permit conditions required by DER. Based upon the evidence presented at hearing, it is concluded that the harms anticipated by Petitioners will not occur. Recommendation Regarding the Assessment of Attorneys Fees and Costs Petitioners did not participate in this proceeding for an improper purpose. The Notice of Intent to Issue was vague as to how interests were balanced and how the mitigation would offset the adverse impacts that concerned Petitioners. The petition was filed and prosecuted in good faith and addressed legitimate concerns of concerned citizenry who reside on adjacent lands.
Recommendation Based upon the foregoing, it is recommended: That a Final Order be entered approving Respondent's Telese's dredge and fill permit number 521715273, pursuant to the Notice of Intent to Issue filed August 21, 1990. That Petitioners should not be assessed attorney fees and costs as they did not participate in these proceedings for an improper purpose.

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.
The Issue Whether Petitioners are entitled to validation of an alleged determination by Respondent of the landward extent of its dredge and fill jurisdiction over a portion of Petitioners' Property?
Findings Of Fact Under former DER rules, those using the vegetative index adopted June 10, 1975, as amended March 11, 1981, DER's dredge and fill jurisdiction upland of the mean high water line depended exclusively on the landward extent of waters of the state, as evidenced by the dominance of certain species of plants that thrive under wet conditions. Only if these indicator species, in the aggregate, were not dominant along the edge of a water body would DER's jurisdiction end at the shoreline. In 1977, Petitioners Fabre and Jacobs acquired more than 43 acres of unimproved land on Garcon Point, fronting Blackwater Bay in Santa Rosa County. By the time of the hearing, their original development plans had changed, but Petitioners still held the property in the hope of subdividing part of it for resale. At Petitioners' request, somebody from the Pensacola office of the Department of Environmental Regulation (DER) inspected the site in the fall of 1979, probably Michael C. Applegate on October 3, 1979. Petitioners wanted to know what DER permits, if any, would be required in order for a road to be built on the property. In connection with their inquiry, they furnished DER a legal description of the parcel and an aerial photograph of the area. Whether DER also received a site plan at that time depicting the proposed road is not shown by the record. DER's pre-application file on the parcel has probably been destroyed. At least in the minds of some DER employees, there is a clear difference between advising whether a particular project falls within DER's permitting jurisdiction, based on a site visit; and making a jurisdictional determination, which may involved planting flags that are then surveyed or photographed from the air. Petitioner Fabre received a letter from Michael C. Applegate, at the time DER's dredge and fill supervisor in Pensacola, which stated: RE: Approximate 43.48 acre parcel located between State Road 191 and Blackwater Bay, Garcon, Section 14, Township I s, Range 28 w, Santa Rosa County, Florida Dear Mr. Fabre: The above referenced land parcel (legal description enclosed) was inspected by a member of this Department to determine the necessity of obtaining dredge and fill permits for future construction activities on the site. It is the opinion of the staff that since the site is dominated by upland vegetation (oaks, pines, etc.) and has no water bodies connecting to the adjacent B1ackwater Bay that dredge and fill permits will not be required for construction activities within the interior of the property; however, any construction along the shoreline or any attempt to connect artificial lakes or canals to Blackwater Bay will require prior permit authorization from this Department in accordance with the provisions of Section 403.087, Florida Statutes, 253.123 and 253.124, F.S. and Section 17-4.28, Florida Administrative Code. Further, should your development of the property result in and [sic] increased stormwater discharge, a stormwater permit may also be required. Joint Exhibit No. 4 In the opinion of DER's expert witness, "along the shoreline" usually means to the edge of open water. In surveying, "shoreline" is a term of art meaning mean high water line. As a practical matter, mean high water line surveys are seldom undertaken because they are complex, expensive and time- consuming. Because Mr. Applegatets letter was undated, Mr. Fabre later asked for a dated reiteration, which DER furnished by copy of a memorandum to the file from DER's William H. Daughdri11, stating: SUBJECT: Review of Undated Correspondence to Frank Fabre [sic] (Baskerville Donovan Engineers) Regarding Proposed Construction on a 43.48 Acre Parcel of Property on Blackwater Bay. On June 23, 1980, I received a call from Mr. Prank Fabre, [sic] during which he requested clarification of a letter written by Mike Applegate in October, 1979. I advised Mr. Fabre that my recollection of the proposed project and subsequent letter was that the excavation was on the interior of the property and not subject to Department of Environmental Regulation's permitting jurisdiction. I cautioned Mr. Fabre [sic] to read the letter carefully and proceed accordingly. On June 24, 1980, I reviewed Mile's letter to Mr. Fabre [ sic] (copy) attached). Mike's letter indicated that no permit would be required for construction activities in the interior of the property; however, construction along the shoreline or any attempt to connect artificial lakes or canals to Blackwater Bay would require a valid Department permit. I called Mr. Fabre and advised him of same. Finally, in reviewing Mr. Applegate's letter to Mr. Fabre, I discovered it to be undated. The photograph attached to the letter referenced a date of October 3, 1979. I assume that the letter to Mr. Fabre went out within a week of the inspection and would therefore be properly dated between October 5 and October 10, 1979. Joint Exhibit No. 3. Having received this memorandum, Petitioners filled out a form Army Corp of Engineers/DER joint application for activities in the waters of the State of Florida. They attached an aerial photograph on which a proposed road is shown, lying more than 200 feet inland; and a drawing representing a proposed community building elevated on piling, approximately 50 feet inland of the mean high water line. Joint Exhibit No. 5. On September 24, 1984, copies of the joint form application with attachments were mailed to DER, along with a cover letter stating, "As we discussed, an application fee is not included since D.E.R. does not have jurisdiction based on enclosed letters from Michael Applegate and William Draughdrill [sic]." Joint Exhibit No. 5. In response, W. Richard Fancher, DER's dredge and fill supervisor, wrote Petitioners, on October 9, 1984: I have reviewed your permit application for a fill road leading to Blackwater Bay, along with the accompanying jurisdictional determinations. However, the Department's dredge and fill jurisdiction has changed significantly since Mr. Applegate's and Mr. Daughdrill's determinations, specifically, since October 1, 1984. Unless you have had the old pre- October 1 jurisdiction verified by our Bureau of Permitting in Tallahassee ("grandfathered"), the Department must consider the project under the post-October 1 jurisdiction and permitting standards. Joint Exhibit No. 7 (emphasis supplied.) A DER "completeness summary" also dated October 9, 1984, was included indicating that Petitioners' application was incomplete for failure to pay the application fee, because, "approximate MHW's" had not been labeled, a claim at least partially belied by attachments to the application, and because certain water quality information allegedly had been omitted. Joint Exhibit No. 7. On October 15, 1984, DER received Petitioners' request for validation with supporting papers. Joint Exhibit No. 9.
Findings Of Fact Joyce K. Anderson and Thomas Barnett have filed an application for issuance of a permit to dredge and fill a small area in the littoral, or "near shore," zone of Gillis Pond, a "sandhill lake" lying in what is known as the "sandhill region" of Central Florida, generally northeast of Gainesville. The dredging and filling as now proposed would be on and waterward of two lakefront lots jointly owed by the permit applicants. They seek by their application, authorization to dredge and fill at only one site on the waterward margin of the two lots with that modified project area reduced in size to a dimension of 12 feet by 25 feet. Fifteen feet of the project would be waterward of the shoreline. The Respondent, the Department of Environmental Regulation, is an agency of the State of Florida charged with the duty of enforcing, as pertinent hereto, the provisions of Chapter 403, Florida Statutes, and Chapter 17-3 and 4, Florida Administrative Code, enforcing the water quality standards contained therein as they relate to dredge and fill projects of this sort, with concomitant permitting jurisdiction over such projects. The permit applicants desire this dredge and fill permit in order to make a safe, comfortable swimming area for Mrs. Anderson's family and friends. Mrs. Anderson desires to remove the tree stumps, roots and vegetation existing in the littoral zone area of the above dimensions in order to make access directly from the shore more comfortable and pleasant, especially for small children who are unable to swim in the deep water off the waterward end of the existing dock. Mrs. Anderson already has a 56 foot dock extending from her property into the lake. The water is 7 feet deep at the waterward end of the dock and the littoral zone containing aquatic vegetation extends beyond the length of the dock in a waterward direction. The project area would extend waterward of the shoreline, a distance of 15 feet, and would parallel the shoreline approximately a distance of 12 feet. The littoral zone vegetation at the site, however, extends waterward from the shoreline 50 to 60 feet. The proposed area to be dredged is quite small in size in relation to the total linear shoreline of the subject lake of approximately 4,000 feet. The dredged material would be excavated to a depth of approximately 6 inches over that 12 by 15 foot area and replaced with clean sand fill. The dredged material removed from the site would be secured on an upland site such that nutrient pollutants from that dredged material could not be leached or carried back into the lake through storm water runoff. Approximately one-third of the shoreline of the lake is bordered by a marsh or wet prairie which is approximately as large in area as the lake itself. The dominant vegetative species in the project area and surrounding the lake, including the marsh, are submerged freshwater species listed in Rule 17- 4.02(17), Florida Administrative Code, including maidencane, sawgrass and a rare aquatic plant, websteria confervodies. Gillis Pond is a Class III water of the state, although its water quality parameters, or some of them, clearly exceed in quality, the minimum standards for Class III waters. Gillis Pond is what is termed an "ultra- oligotrophic lake, which means that its waters are characterized by a high level of transparency and very low nutrient content, that is to say that they are essentially pristine in nature. An oligotrophic lake such as this is very sensitive to any addition of nutrient pollutants. Even a small addition of nutrients to such water can cause an imbalance in the fauna and flora which have evolved to become dependent upon a low nutrient aquatic environment. Specifically, the rare aquatic plant named above is very sensitive to any enhanced nutrient levels and thus serves as a barometer of the water quality in this body of water. The addition of any nutrient pollutants to the lake, even in small amounts, might alter the chemical balance of the water in a derogatory manner so that the websteria confervodies might be eliminated. The elimination of this species from the littoral zone vegetation band surrounding the lake would likely result in other forms of vegetation supplanting it, altering the balance and makeup of the community of fauna and flora native to the lake and possibly hastening the progress of the lake toward eutrophication and degradation. The present water quality in the lake is such that dissolved oxygen and other criteria are better than the Class III water quality standards. The vegetation in the littoral zone of the lake and extending out as much as 50 to 60 feet waterward performs a significant function in uptaking and fixing nutrient pollutants that wash into the lake from storm water runoff from the surrounding uplands. Inasmuch as 30 to 40 feet of this belt of littoral zone vegetation would remain waterward of the dredged and filled area if the permit is granted, the nutrient uptake function of the vegetation in the littoral zone would not be significantly degraded. There are two locations where littoral zone vegetation has been removed in a similar fashion and water quality and flora and fauna communities characteristic of an oligotrophic lake are still present and healthy. Further, there is an extremely low nutrient level in the lake at the present time, and no significant amount of nutrient pollutants are leached or washed into the lake through septic tanks, storm water runoff or other sources. There is no question that the project as proposed would result in some slight, transitory degradation of water quality in the form of increased turbidity and reduced transparency. Turbidity will be caused during and shortly after the dredging and filling operation itself, caused by stirring up of bottom peat or sediments and by removal of a 12 by 15 foot area of aquatic vegetation in the littoral zone of the lake. Turbidity curtains in still waters such as involved here, can substantially reduce the spread of turbidity caused by the stirring up of bottom material and can substantially reduce the period of its suspension in the water by containing it at the dredged site. The vast majority of the littoral zone vegetation surrounding and waterward of the area to be dredged will remain such that the nutrient uptake function will be essentially undisturbed, thus any adverse impact on water quality will be insignificant. In terms of cumulative effect of allowing a multiplicity of such projects, not even a 10 percent loss of the littoral zone band of vegetation in the lake, which would be the maximum possible loss if all riparian land owners were allowed a similar size dredged and filled area on the front of their lots, would cause a violation of Department water quality standards. Parenthetically, it should be pointed out that such riparian owners cannot be prevented by any water quality criteria in Chapter 403 or Chapter 17, Florida Administrative Code, from having access to the lake in front of their lots. Such human traffic will have the gradual affect of destroying a significant amount of the littoral zone vegetation on and waterward of those lots (which is a cause and result the Department is powerless to regulate). By confining the destruction of littoral zone vegetation to such a small area as that involved in the application at bar and thus guaranteeing adequate, comfortable access for the riparian owner, the survivability of the remaining critical littoral zone vegetation will be significantly enhanced.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence in the record and the candor and demeanor of the witnesses, it is, therefore RECOMMENDED: That the application of Joyce K. Anderson and Thomas Barnett for a dredge and fill permit as described in the modified and amended application be GRANTED; provided, however, that turbidity curtains are used during all dredging and filling activity and for a reasonable time thereafter until turbidity caused by the project has settled out of the water column.

The Issue The issue for determination in this proceeding is whether Respondent, E. Speer and Associates, Inc. (the "Applicant"), should be granted a permit for the construction of a permanent docking facility pursuant to Sections 403.91-403.929, Florida Statutes, and Florida Administrative Code Chapter 17.
Findings Of Fact Whether Quantified Hydrographic Studies Are Necessary For All Marina Applications To Provide Reasonable Assurance That Flushing Is Adequate To Prevent Violations of Water Quality Standards Speer's Exceptions Nos. 1, 4, 5, 6, 7 and 8 in whole or in part take exception to the Hearing Officer's conclusion (stated as a finding of fact) that it is not possible to demonstrate adequate flushing without "quantifying flushing rates and pollutant dispersal rates using objective methods and appropriate hydrodynamic data." (R.O. at 20, 22-24, 47, 49-50, 54, 57-58; F.O.F. Nos. 33, 35, 38-39, 40, 43-45, 64, 66, and 69) It is clear from the tenor of the entire recommended order that the Hearing Officer believes that as a matter of law an expert's opinion is not sufficient to provide reasonable assurances that flushing will be adequate to prevent violations of water quality standards unless that opinion is based on quantified conclusions generated by objective methods and appropriate hydrodynamic data. (R.O. at 47, 49-50, 57-58) Thus, for example, the Hearing Officer opines that quantification of flushing rates and pollutant dispersal rates using objective measurements of appropriate hydrodynamic data is an essential element of the prima facie showing required to be made by the applicant. (R.O. at 47; C.O.L. No. 11) The Hearing Officer places great significance an the following excerpt from the opinion in 1800 Atlantic Developers v. Department of Environmental Reculation, 552 So.2d 946 (Fla. 1st DCA 1989), rev. den., 562 So.2d 345 (Fla. 1990): 1800 Atlantic filed 34 exceptions to the recommended order, most of which were denied in the Department's final order . . . . The final order approved and adopted most of the findings of fact and conclusions of law in the recommended order and denied the permit. The following stated rulings and reasons there for are significant to the issues on this appeal. (emphasis added) We must note at this point that there is no finding of fact in the hearing officer's recommended order that quantifies how productive the marine habitat may be in this case, and no record support for the suggestion that there would be some quantifiable diminution in the quality of the marine habitat attributable to this project [footnote omitted]. (emphasis added) Exception 23 filed by 1800 Atlantic challenged the hearing officer's finding that the project will adversely affect the conservation of fish and wildlife, fishing or recreational values, and marine productivity in the vicinity . . . The Department rejected this exception based upon the hearing officer's general statements, without any quantification whatsoever, of adverse effects upon these matters . . . (emphasis added) 1800 Atlantic, 552 So.2d at 951-952. I do not concur that 1800 Atlantic stands for the proposition that quantified hydrographic measurement of flushing is in all cases an essential element of a prima facie showing that a marina project will not cause violations of water quality standards. Notwithstanding the above noted statement of the court in 1800 Atlantic that "there is no finding of fact . . . that quantifies 'how productive the marine habitat may be' . and no record support . . . that there would be some quantifiable diminution in the quality of marine habitat attributable to [the] project," 552 So.2d 951, the court did not reject the finding that the project adversely affected the conservation of fish and wildlife, fishing or recreation values, and marine productivity. Indeed, had the court rejected the above finding due to lack of quantified findings the court would never have gone on to reach the issue of mitigation because in 1800 Atlantic mitigation could only become relevant if the applicant was unable to provide reasonable assurance that the project satisfies the public interest criteria of Section 403.918(2) (a), Florida Statutes. See Section 403.918(2)(b), Florida Statutes. I do agree that in some cases quantified hydrographic studies of flushing may be required in order to provide reasonable assurances. Thus, in Rudloe v. Dickerson Bavshore, Inc., 10 FALR 3426 (DER Case No. 87-0816, June 9, 1988), my predecessor held that a dye tracer study was necessary to provide quantitative information about dilution rates and directions on dispersion of pollutants emanating from a proposed marina site which was in "close proximity" to Class II waters approved for shellfish harvesting. 10 FALR at 3447-48. However, the need for such quantified studies must be determined on a case by case basis and is not required as a matter of law for all marinas. 5/ Far me to determine as a matter of law that experts may establish a fact only by certain types of evidence would be an unwarranted and unwise intrusion into the scientific domain of the expert. Thus, in Kralik v. Ponce Marine, Inc., 11 FALR 669, 671 (DER Final Order, Jan. 11, 1989), my predecessor held that expert testimony with regard to flushing does not lack credibility just because a hydrographic study had not been conducted. Of course, the finder of fact has the ultimate say on how much weight an expert opinion should be given if it is not based on a quantified study. Thus, whether an expert testifying on adequacy of flushing has conducted a quantifiable hydrographic study merely goes to the weight of the evidence. Kralik, 11 FALR at 671. I only conclude that a quantified hydrographic study for a proposed marina is not in all cases essential for a showing of reasonable assurances that water quality standards will not be violated. Accordingly, to the extent that the Hearing Officer's findings of fact state that a quantified hydrographic study is required in all cases as a prima facie element of a showing of reasonable assurance that a project will not violate water quality standards, I reject such statement as a mislabled and incorrect conclusion of law. Reasonable Assurance That Flushing Is Adequate To Prevent Violations of Water Quality Standards I read Speer's Exceptions Nos. 1, 3, 4, 5, 6, 7 and 8 in whole or in part as taking exception to the Hearing Officer's finding that under the facts of this case a quantified hydrographic study was needed in order to provide reasonable assurance that the project would not cause violations of water quality standards, and that because such a quantified hydrographic study had not been conducted, reasonable assurances had not been provided. (F.O.F. Nos. 33, 35, 38- 39, 40, 43-45, 64, 66 and 69) As noted by the Hearing Officer, the applicant's expert testimony concerning the adequacy of the flushing consisted of general statements describing visual observations of river and tidal flows which, together with past experience and knowledge of the general area of the project, formed the basis for the experts' opinions that a quantified hydrographic study was not necessary for this project. (R.O. at 22-23) Thus, far example, Mr. Charles C. Isiminger, accepted as an expert in marina design and hydrographic engineering testified that based on his knowledge of the area, its riverine and tidal flows, a hydrographic documentation was not needed to provide reasonable assurance that the project would not cause water quality violations. Mr. Isiminger also testified that any pollutants entering the water from the marina would be flushed out of the area within one tidal cycle. (Tr. at 65-66, 70, 77- 79, 93, 110, 125, 128, 134) Mr. Thomas Franklin, an environmental supervisor from the Department testified that: the hydrographic survey was not really necessary due to the location of the project being in open waters and in close vicinity to the Inlet with a large volume of tidal waters moving in this area, plus the fact that it was further enhanced by flushing due to the St. Lucie River being -- basically coming around Hell Gate point [sic] and funneling out into this estuary. (emphasis added) TR at 437. Other experts also testified that the area was well flushed and that a quantified hydrographic study was not needed in this case. (Jacqueline Kelly, Tr. at 187; John Meyer, Tr. at 319, 322, 341; Gerald Ward, Tr. at 44749) 6/ Speer asserts that the Hearing Officer's finding that a quantified hydrographic study is required in this case cannot stand in light of the unrebutted expert testimony that the marina site will be well flushed and that the rate of flushing provides reasonable assurances the water quality standards will not be violated. I have found no competent substantial evidence in the record which would support a finding that under the facts of this case a quantified hydrographic study is required. I did note that in Footnote 21 of the Recommended Order (R.O. at 20) the Hearing Officer states: Tidal range is only one of the types of data used to quantify flushing rates and pollutant dispersal rates. See TR at 78. Other appropriate data include: overall flow rates, mid tide flow, flow amplitude (the magnitude of the flow without regard to direction, i.e., speed as opposed to velocity), horizontal current distribution, downstream plume characteristics, and field verification using a dye tracer. All of this data is needed to fully describe and quantify flushing rates and pollutant dispersal rates. (citing testimony of Mr. Isiminger at Tr. 88-94) At first blush this may appear to be competent substantial evidence supporting a finding that a quantified hydrographic study is necessary in this case. However, when the testimony is read in its complete context, it is clear that Mr. Isiminger is testifying as to what is necessary to do a hydrographic study when one is needed, and is not testifying that such a study is needed in this case. (Tr. 88-94). I also note that the record contains a memo written by Dr. Kenneth Echternacht, a hydrographic engineer employed by the Department. (Tr. at 67-70) This memo was admitted without objection. (Tr. at 23) The memo states in part that "without . . . hydrographic documentation, reasonable assurance cannot be given that the project will not cause problems." (Tr. at 70; Pet. Exh. No. 10) 7/ Dr. Echternacht was not called as a witness at the hearing and the letter was not offered as evidence of the opinion of Dr. Echternacht or the Department at the time of the de novo hearing. To the contrary, the above noted testimony of Mr. Franklin and the testimony of Jacqueline D. Kelly, an environmental specialist of the Department accepted as an expert in evaluating impacts of environmental dredge and fill projects (Tr. at 187, 195; R.O. at 3), clearly establish that at the time of the de novo hearing the Department was of the opinion that further hydrographic documentation was not needed. The Hearing Officer noted that Mr. Meyer testified that the flushing is a "very, very complicated dynamic situation." (Tr. at 320). The testimony was as follows: Q. So you don't know for sure whether the currents here impact this at all or stay offshore from it? A. Oh, the currents definitelv affect it, and you do have interchange -- as I mentioned before, a very high rate of interchange on a daily basis on every tide. Q. Are you saying that the current that flows through here every day flows right through the site? A. We're dealing with two different things here. We're dealing with your currents, your general migration of waters from the estuary from the inland areas down. You're also dealing with tidal effects coming in and out, and it's a very, very complicated dynamic situation. For me to try to tell you exactly how these things work would be impossible without having a very, very long drawn-out expensive study done on the entire area, and I have not reviewed any studies like that. Tr. at 319-20 (emphasis added) When taken in its context it is clear that Mr. Meyer is testifying that there is a very high rate of exchange on a daily basis on every tide. The fact that he viewed the exact details of the flushing as very complicated in no way retracted his statement that there was a very high rate of exchange on every tide. My review of the record leads me to concur with Speer that no testimony, either on direct, cross-examination, or examination by the Hearing Officer, nor any other evidence was introduced to rebut the expert testimony presented by Speer and the Department that flushing on the site was adequate to provide reasonable assurance that water quality standards will not be violated. 8/ As a general rule, the trier of fact may not arbitrarily reject uncontroverted evidence as proof of a contested fact. Merrill Stevens Dry Dock Co. v. G. & J. Investments, 506 So.2d 30 (Fla. 3d DCA 1987), rev. den., 515 So.2d 229 (Fla. 1987); City of St. Petersburg v. Vinoy Park Hotel, 352 So.2d 149 (Fla. 2d DCA 1977); In Re: Estate of Hannon, 447 So.2d 1027 (Fla. 4th DCA 1984). This does not mean that a mere scintilla of unrebutted evidence is sufficient to establish a contested fact in an administrative hearing. At least in the context of administrative proceedings, the unrebutted evidence still must be competent substantial evidence to support a finding of fact. 9/ There is no suggestion that the Hearing Officer rejected the unrebutted testimony of the experts of Speer and the Department as not being competent substantial evidence. In fact, in the light of the testimony of Mr. Isiminger (Tr. at 65- 66), Mr. Ward ( Tr. at 447-449), Mr. Meyer (Tr. at 238- 239), and Mr. Franklin (Tr. at 345-350), it is beyond peradventure that there is competent substantial evidence to support a finding that flushing is adequate to provide reasonable assurance that the marina will not cause violations of water quality standards. It is clear from the context of the Recommended Order that the Hearing Officer believed that reasonable assurance had not been provided only because he believed that a quantified hydrographic study was required as a matter of law. Although I reject the Hearing Officer's conclusion that a quantified hydrographic study must be conducted as a matter of law for all marina applications, I must still determine whether a quantified hydrographic analysis is required under the facts of this case. In Rudloe v. Dickerson Bayshore, 10 FALR 3426 (DER Final Order, June 9, 1988) it was held that a hydrographic study was not adequate because it did not include a quantified dye tracer study. Id., 10 FALR at 3448. In Rudloe, as in this case, the marina was located in Class III waters, but near Class II waters. However, in Rudloe, the marina site was much closer to the Class II waters (approximately 1,700 feet in Rudloe (10 FAIR at 3430) as compared to approximately 8,000 feet in this case). (R.O. at 16, F.O.F. No. 26) Also, the Rudloe case is significantly different from this case in that competent substantial expert opinion was presented in Rudloe that the marina would adversely impact the Class II shellfish harvesting area. See Rudloe, 10 FALR at 3433-35, 3437-38 (testimony of DNR expert that operation of marina would result in closure of waters to the harvest of shellfish; testimony of Dr. Robert Livingston that the hydrographic drogue studies conducted were inadequate.) In this case, neither expert nor lay testimony was offered by Barringer to show that operation of the marina would result in violation of water quality standards or have any adverse impact on the Class II shellfish waters. 10/ I conclude that the facts of this case as found by the Hearing Officer are not sufficiently similar to the facts of Rudloe so as to justify holding as a matter of law a quantified hydrographic study is necessary to establish the required reasonable assurances. Since the record contains competent substantial evidence that flushing is adequate to provide reasonable assurance that the marina will not cause water quality violations, and since there is no competent substantial evidence in the record to support the Hearing Officer's contrary finding, I must accept the exception of Speer and reject the Hearing Officer's findings of fact to the contrary. In this case I note that I am not so much rejecting findings of fact as rejecting a conclusion of law. As I noted, the Hearing Officer's finding is really based on a conclusion of law which I reject. This leaves only unrebutted competent substantial evidence that there will be adequate flushing to provide reasonable assurance that the operation of the marina will not result in water quality violations. There is no rational basis to reject this unrebutted competent substantial evidence. Therefore, I must accept as proven that the applicant has provided the reasonable assurances that operation of the marina will not result in water quality violations. Merrill Stevens Dry Dock; City of St. Petersburg; Estate of Hannon; supra, Effect On Class II Waters Speer's Exceptions Nos. 7 and 8 take exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the marina would not have a "negative effect" an the Class II waters of the St. Lucie Inlet and the Great Pocket. (F.O.F. No. 43) Rule 17-312.080(6)(b), Fla. Admin. Code provides: The Department also shall deny a permit for dredging and filling in any class of waters where the location of the project is adjacent or in close proximity to Class II waters, unless the applicant submits a plan or proposes a procedure which demonstrates that the dredging or filling will not have a negative effect on the Class II waters and will not result in violations of water quality standards in the Class II waters. In this case expert testimony was presented by Speer and the Department that due to the distance of the marina site from the Class II waters (8,000 feet) the marina site was not in close proximity to the Class II waters, and due to the rapid flushing of the area, the construction and operation of the marina would neither have a negative effect nor would result in violations of water quality standards in the Class II waters of St. Lucie Inlet and the Great Pocket. (Isiminger, Tr. at 96, 126-27; Meyer, Tr. at 254-55) I find that the record contains no competent substantial evidence to rebut the evidence introduced by Speer and the Department that the marina will have no negative effect on Class II waters and will not result in violation of water quality standards in Class II waters. Accordingly, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersburg; In Re: Estate of Hannon; supra. Reasonable Assurance That Operation Of The Marina Will Not Result In Prop Dredging Or Violations Of The State Water Quality Criterion For Turbidity Speer's Exceptions Nos. 1, 2, 9-12, and 16 in whole or in part take exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the boat traffic from operation of the marina would not cause prop dredging or violations of the water quality criterion for turbidity. (F.O.F. Nos. 33-34, 45, 48, 52-53, 64, and 67) 11/ On one hand, there was testimony that the depths of the marina, in combination with the size of boats allowed in the various slips, would allow for a one foot clearance from the bottom of the boats to the bottom of the marina, and that this clearance, in combination with speed limits in the marina, would provide reasonable assurance that operation of the marina would not result in prop dredging or turbidity violations. (Isiminger, Tr. at 104-107, 118; Meyer Tr. at 263-65, 299, 304- 305; Kelly, Tr. at 189-190; Ward, Tr. at 460) On the other hand, Bruce Graham, admitted as an expert in marine biology testified that: "A large boat, three feet from the bottom, I think would resuspend sediment." (Graham, Tr. at 378). The Hearing Officer, noting that when asked if one foot clearance is sufficient to prevent prop dredging and resultant turbidity violations, a Department witness, testified: I would have to say that we simply don't have enough documentation to know this for a fact. We know that a foot gives us a degree of comfort that there will not be prop wash. In certain instances -- a tug boat, for instance, you know, with huge engines, you're going to have prop wash over a much -- over a large area and with probably much more than a foot of clearance. But for the normal, typical marina a foot, as I say, gives us a degree of comfort that we have settled on. Neyer, Tr. at 264. The Hearing Officer concluded that the witnesses of Speer and the Department could not explain the reasons or efficacy of the "one foot policy" except to say that in their experience the one foot policy was adequate to prevent prop dredging and turbidity violations. (R.O. at 28 n.35)0 The Hearing Officer thus found that Speer and the Department failed to "prove up" the one foot policy -- i.e., failed to elucidate and explicate the reason for the policy. 12/ Clearly the Hearing Officer placed more weight on the testimony of Mr. Bruce Graham than that of Isiminger, Meyer, Kelly and Ward. Since I cannot say that the testimony of Graham was not competent substantial evidence, I am not at liberty to reweigh the evidence or reject the Hearing Officer's finding of fact. See, Florida Dept. of Corrections v. Bradley, 510 So.2d 1122 (Fla. 1st DCA 1987); Heifetz v. Department of Business Regulation, 475 So.2d 1277, 1281 (Fla. 1st DCA 1985); Sections 120.57(1)(b)10., and 120.68(10), Florida Statutes. Speer contends that Barringer presented no evidence that prop dredging will cause sufficient turbidity to violate the state water quality turbidity criterion of 29 NTUs. 13/ That contention misses the point. The burden is on Speer to establish by the preponderance of evidence that reasonable assurance has been provided that operation of the marina will not result in violations of the water quality criterion for turbidity. Florida Department of Transportation v. J.W.C., Co., 396 So.2d 778 (Fla. 1st DCA 1981). The Hearing Officer, as the finder of fact, concluded that Speer failed to do so. Accordingly, I reject the exception of Speer and accept the Hearing Officer's finding of fact that Speer failed to provide reasonable assurance that operation of the marina would not cause prop dredging or violations of the state water quality criterion for turbidity. Manatee Impacts and the Public Interest Test Speer's Exceptions Nos. 13 and 17 take exception to the Hearing Officer's finding that Speer failed to do a quantified study of impacts to manatees and therefore failed to provide reasonable assurance that the marina will not have an adverse impact on manatees, their migratory patterns, and their habitat. (F.O.F. Nos. 61, 64 and 68) The Hearing Officer reasoned as follows: Instead of a traffic study, the Applicant and DER presented evidence in the form of general statements that manatees need not migrate north and south through the approach channel. According to the Applicant and DER, manatees can migrate across the project site by one of two alternative routes. They can migrate in one or two feet of water under moored boats and then under wave breaks on the north and east piers, or they can migrate in the shallow water landward of the west boundary of the project. That evidence was not persuasive and was controverted by competent, substantial, and persuasive evidence that manatees would be deterred from migrating under the project footprint by substantial obstacles in their path. Manatees migrating under the project footprint would be exposed to 86 or more moving boats with powerful engines and drafts of four to five feet in waters covering approximately 20,800 square feet. It could be argued, or course, that 86 or more boats would not be moving in and out of the marina at one time. However, it is impossible to estimate occupancy rates, length of stay, and frequency of boat trips without a traffic study. (R.O. at 35, n. 51) As Speer's exception notes, there was testimony that because of the width of the river and boat speed restrictions in the project area, there would be no adverse impacts an the manatee from the marina. (Kelly, Tr. at 162; Meyer, Tr. at 255-56, 331- 32; Isiminger, Tr. at 130) The St. Lucie/Jupiter/Hobe Sound waterways are a major travel corridor for manatees. (DER Exh. No. 4) Between 1974 and December 1990, there were ten water craft related manatee fatalities within the boating sphere of influence of the project. (DER Exh. No. 4) In order to reduce impacts on the manatees, the proposed permit contains the following specific conditions: S.C. No. 13: The permittee agrees to install and maintain a minimum of one manatee education/display on the main access pier during and after construction. S.C. No. 15: The permittee agrees that any collision with a manatee shall be reported immediately [to DNR and U.S. Fish and wildlife Service]. S.C. No. 18: The permittee shall post four (4) manatee area/slow speed signs, two of which would be spaced along the perimeter pier and two of which would be located on the outside of the marina for all boating traffic to observe within the marina facility. (DER Exh. No. 3) 14/ There was testimony that the piers, once constructed, would not impair the passage of manatees. (Isiminger, Tr. at 114- 115) On the other hand, there was some testimony that manatees may have to go around the project rather than through it. (Meyer, Tr. at 311) The existing boat traffic past the site of the project to the Inlet was "rough1y estimated" at 50 to 100 boats a day. (Meyer, Tr. at 337) The U.S. Fish and Wildlife Service determined that "while [the project] may negatively affect, it is not likely to jeopardize the continued existence of the West Indian Manatee." (Tr. at 120-21) The Hearing Officer concluded that reasonable assurance as to adverse impacts on manatees could not be provided absent a quantified traffic study. (R.O. at 35, n. 51) In Coscan Florida, Inc. v. Department of Environmental Regulation, 12 FAIR 1359 (DER Final Order March 9, 1990), the Department held that the information needed to determine a marina's impact on manatees and the necessary actions to mitigate such impacts must be decided an a case by case basis. For example, in Sheridan v. Deep Lagoon Marina, 11 FALR 4710 (DER Final Order, Aug. 24, 1989), 15/ a marina sought to expand by adding 113 new wet slips. The marina was required to develop a manatee protection plan far the surrounding portions of the Caloosahatchee River, all new slips were limited to sail boats until the manatee protection plan was implemented and enforced, and power boat occupancy was limited to 75% of the total 174 wetslips in any event. The marina also made available a wet slip for use by the Florida Marine Patrol. In this case there is evidence of significant boat related manatee fatalities in the boating sphere of influence of the proposed marina. There is also evidence of existing traffic of 50-100 boats per day past the project site. In view of the fact that this project would add 86 slips and a public fueling facility, it seems likely that that the project will significantly increase both boat traffic and the threat of manatee collisions. Accordingly, I concur with the Hearing Officer that there is competent substantial evidence to support a finding that further studies are needed to determine what, if any, additional manatee protection conditions are needed to provide reasonable assurance that manatees will not be adversely affected. I conclude that the applicant did not provide reasonable assurance that the operation of the marina will not have an adverse impact on manatees, their migratory patterns, and their habitat, and therefore failed to provide reasonable assurance that the project is not contrary to the public interest. Therefore, I reject the exception of Speer. Cumulative and Secondary Impacts Speer's Exception No. 15 takes exception to the Hearing Officer's finding that the applicant failed to provide reasonable assurance that there will be no adverse cumulative pacts created either by the cumulative effects of the object and existing similar projects, or by secondary pacts of the project itself. (F.O.F. No. 66) 16/ Cumulative impact analysis takes into consideration the cumulative impacts of similar projects which are existing, under construction, or reasonably expected in the future. Conservancy v. A. Vernon Allen Builder, supra; Section 403.919, Florida Statutes. Secondary impact analysis considers the impact of the project itself and of any other relevant activities that are very closely linked or causally related to the permitted project. Conservancy, 580 So.2d at 778; J.T. McCormick v. City of Jacksonville, 12 FALR 960, 980. 17/ Thus, in Conservancy the secondary impact analysis was required to consider the environmental impacts of development of 75 estate homes on an island where the development would be reasonably expected as a result of the permitted laying of a subaqueous sewer line. Similarly, in del Campo v. Department of Environmental Regulation, 452 So.2d 1004 (Fla. 1st DCA 1984), the Department was required to consider the environmental impacts of the foreseeable development of an island facilitated by the permitted building of a bridge to the island. In this case there is competent substantial evidence that there are other marinas located 1,750 feet downstream in Willoughby Creek, and 5,000 feet downstream in Manatee Pocket. (R.O. F.O.F. 31; Isiminger, Tr. at 112; Meyer, Tr. at 261) The record contains competent substantial evidence that the cumulative impact of the project and the existing marinas in Willoughby Creek and Manatee Pocket will not result in violations of state water policy. (Isiminger, Tr. at 125; Kelly, Tr. at 167) I cannot say that the testimony of Isiminger and Kelly on cumulative impacts is not competent, substantial evidence. In light of the fact that there is no competent substantial evidence to indicate that cumulative impacts would result in water quality violations, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersbur; In re: Estate of Hannon; supra. As to secondary impacts, the Hearing Officer pointed out that Speer did not introduce any evidence as to whether there would be secondary impacts to water quality as the result of further development or increased utilization of the uplands facilities. (See F.O.F. 66, n.59, R.O. at 39) Such further development or increased utilization of upland facilities is reasonably foreseeable and would be very closely linked or causally related to the building of an 86 slip marina with public fuel services. As noted above, the applicant has the burden of providing reasonable assurances as to cumulative and secondary impacts. Brown v. DER, supra; Conservancy, supra. However, neither the pleadings nor the pre-hearing stipulation raised the issue of the adequacy of the secondary impact analysis. In a case such as this where the Department's notice of intent to issue a permit has been challenged by a third party, the applicant's prima facie case need only include the application and the accompanying documentation and information relied on by the Department as the basis of its intent to issue. Florida Department of Transportation v. J.W.C., 396 So.2d 778, 788 (Fla. 1st DCA 1981). The petitioner challenging the permit must identify the areas of controversy and allege a factual basis for its contentions that the applicant did not provide the necessary reasonable assurances. J.W.C., 396 So.2d at 789. See also Woodholly Assoc. v. Department of Natural Resources, 451 So.2d 1002, 1004 (Fla. 1st DCA 1984). Since Barringer did not identify this issue and did not allege any factual basis for a contention that the secondary impact analysis was inadequate or incorrect, I may not rule on the issue in this order. Miscellaneous Exceptions To Findings of Fact Speer's Exception No. 14 takes exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the project will have no adverse impact on (1) the relative value of functions being performed by areas affected by the project, including seagrasses, shell fish, and fin-fish, and (2) recreational and commercial values in the vicinity. (F.O.F. No. 64) Speer contends that this finding is not supported in the record by competent substantial evidence and is contrary to unrebutted testimony of Ms. Kelly and Mr. Isiminger. (Kelly, Tr. at 159, 161-62, 165-67; Isiminger, Tr. at 73) I cannot say that the testimony of Isiminger and Kelly is not competent, substantial evidence, and I find no evidence in the record to rebut the testimony of Kelly and Isiminger. Therefore, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersburg; In re: Estate of Hannon; supra. Speer's Exception No. 3 takes exception to the Hearing Officer's finding that Speer failed to provide a current water quality analysis. (F.O.F. No. 35) A water quality analysis was submitted in April of 1990, shortly after the permit application was filed. (R.O. at 2, 19; F.O.F. No. 34) I find no competent substantial evidence in the record to suggest any reason for believing that the water quality has changed since April of 1990. I agree with Speer that, absent some specific reason for believing that the water quality has changed since the date of a study conducted contemporaneously with the permit application, there is no requirement to provide an updated water quality analysis. RULINGS ON EXCEPTIONS TO CONCLUSIONS OF LAW Need For Quantified Hydrographic Study Speer's Exceptions Nos. 1, 7 and 9, in whole or in part, take exception to the Hearing Officer's conclusions of law that a quantified hydrographic study was needed to provide reasonable assurances that the operation of the marina would not result in violations of water quality standards and would would not have a negative effect on Class II waters. For the reasons stated in Parts III(1), (2) and (3) above, I accept this exception and reject the above noted conclusions of law. Introduction Of Issues Not Set Forth In Pleadings Or Pre-Hearing Stipulations Speer's Exceptions Nos. 1, 2, 3, and 5, in whole or in part, take exception to the Hearing Officer's consideration of issues of (1) the need for a quantified hydrographic study, (2) the proximity of the site to Class II waters, (3) turbidity and prop dredging, (4) cumulative impacts, and (5) the need for a quantified study on manatee impacts. For the reasons set forth in Part 111(6) above, I agree that, absent waiver, a petitioner challenging an intent to issue a permit may not raise issues at the hearing which were not raised in the pleadings or pre-hearing stipulations. However, in this case the issue of manatee impacts was raised in the pleadings, and Speer was on notice that it had the burden of proof on that issue. As to the other issues, even if I accepted far the sake of argument that they were not raised in the pleadings or pre-hearing stipulations, Speer failed to timely object to the raising of these issues at the hearing and therefore waived any objection. See Sarasota County and Midnight Pass Society v. Department of Environmental Regulation, 13 FAIR 1727 (DER Final Order, April 4, 1991). Therefore, I reject the above exceptions. Proximity To Class II Waters Speer's Exception No. 2 takes exception to the Hearing Officer's conclusion of law that Speer was required to submit a plan which demonstrated that the marina would not have a negative effect on Class II waters. (C.O.L. Nos. 12 and 13) I do not agree that where a proposed marina site is 8,000 feet from Class II waters and where the site is rapidly flushed as noted in Parts 111(1), (2) and (3) above, that the site is in close proximity with the Class II waters within the meaning of Rule 17-312.080(6), Fla. Admin. Code. Accordingly, I accept this exception and reject the above note conclusion of law. Public Interest Test Speer's Exception No. 4 takes exception to the Hearing Officer's conclusion of law that Speer failed to provide reasonable assurance that the project was not contrary to the public interest. (C.O.L. Nos. 17 and 20) For the reasons set forth in Parts III(4) and (5) above, I reject this exception. Cumulative Impacts Speer's Exception No. 5 takes exception to the Hearing Officer's conclusion of law that Speer failed to provide reasonable assurances that cumulative impacts would not result in water quality violations, and that such assurances could only be provided by a quantified study. For the reasons set forth in Parts III (1), (2), (3) and (6) above, I accept this exception and reject the above noted conclusions of law. Modification Of Permit Conditions Speer's Exception No. 6 takes Exception to the Hearing Officer's conclusions of law Nos. 24-34. These conclusions of law concern questions of the authority of the Hearing Officer and me to modify the conditions of the permit. I agree with Speer that since none of the parties have requested any modifications, these conclusions of law are irrelevant. 18/ Therefore I accept the exception and reject the above noted conclusions of law as irrelevant. Miscellaneous Speer's Exception No. 8 in part takes exception to the Hearing Officer's conclusion that Speer and the Department failed to provide reasonable assurance as to prop dredging and turbidity violations because neither Speer nor the Department sufficiently proved the basis for the one-foot clearance policy. For the reasons set forth in Part III(4) above, I reject this exception. Speer's Exception No. 8 in part takes exception to the Hearing Officer's conclusion that the question of whether mitigation is adequate is a question of law. I agree with the Hearing Officer and reject this exception. See 1800 Atlantic Developers v. Department of Environmental Regulation, 552 So.2d 946, 955 (Fla. 1st DCA 1989).
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is recommended that Respondent, Department of Environmental Regulation, enter a Final Order denying the application for a permit to construct the proposed project and denying the request for determination of improper purposes. RECOMMENDED in Tallahassee, Leon County, Florida, this 16th day of June, 1992. DANIEL MANRY Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399 1550 (904) 488 Filed with the Clerk of the Division of Administrative Hearings this 16th day of June, 1992.
The Issue Respondent Jacksonville Shipyards, Inc. (JSI) filed a permit application with the State of Florida, Department of Environmental Regulation, (DER), for permission to conduct maintenance dredging in a basin associated with its shipyard operation. This permit application was made in accordance with Chapter 403, Florida Statutes, and Chapter 17, Florida Administrative Code. In the face of DER's statement of intent to grant this permit, George H. Hodges, Jr., (Petitioner), has petitioned in protest. Therefore, the issues to be considered in this dispute concern the entitlement of JSI to the grant of an environmental permit for maintenance dredging of its shipyard basin.
Findings Of Fact DER is an agency of the State of Florida charged with the environmental protection of waters within Florida. Its authority includes regulatory powers announced in Chapter 403, Florida Statutes, and Chapter 17, Florida Administrative Code. Certain activities involving state waters require permission from DER before they be lawfully undertaken. Among those activities are dredge projects such as contemplated by JSI in its pending request to be allowed to maintenance dredge as much as 66,000 cubic yards of material per year from its shipyard basin located in Jacksonville, Duval County, Florida. This is an undertaking which is envisioned by Chapter 403, Florida Statutes, related to the permit responsibility of DER. It is specifically addressed by Rule 17-4.28, Florida Administrative Code, in which is found the statement of permit requirements for dredge and fill activities. JSI, the applicant, operates a facility known as Bellinger Shipyard, which is engaged in the repair and maintenance of commercial and naval vessels. This enterprise includes the drydocking of vessels upon which repairs are effected, through the use of several drydock chambers in shipyard basin. In the course of the maintenance, a technique known as "gritblasting" is employed. The purpose of this "gritblasting" is to clean the ships in anticipation of repainting. On occasion the "gritblasting" would remove all coats of paint down to the metal finish of the ship. The paints being removed contain antifouling and anticorrosive materials. Those materials have, among other properties, the ability to repel marine organisms, causing their mortality. The "gritblasting" process utilizes a material known as "black beauty." This is a waste product from firing power plant boilers and it contains iron, silica, aluminum, titanium, magnesium, lime, penta oxide (P2O5), sodium oxide, sulfur trioxide and potassium oxide. The "black beauty" is applied through the use of a pressurized system which forces the material onto the treated surface under pressure of 70 to 85 pounds per square inch. After the preparation is made, vessels under repair are repainted, and similar paint with antifouling and anticorrosive properties is reapplied. During the "gritblasting" process, dust is generated and a portion of that material finds its way into the water within the basin. Other particles being removed drop to the deck surface of the drydock. When paint is reapplied to the surface of a vessel undergoing repair, it is given the opportunity to dry and the vessel is then refloated and removed from the drydock. To do this, the drydock itself is submerged. When the vessel has exited the drydock facility, the drydock resurfaces and is allowed to dry out. The material which has been removed from the surface of the repaired vessel is then shoveled into containers and transported to an offsite sanitary landfill for disposal. This material removed includes the "gritblasting" compound and paint which has been stripped from the surface of the vessel. When the drydock is submerged following vessel servicing, the inference can be drawn that a certain amount of the materials on the drydock deck surface will be introduced into the water within the basic before the drydock is resurfaced. The arrangement for refloating the vessel is the reverse of the technique employed in lifting the vessel out of the water for maintenance. When the vessel is brought in for service, it is guided into a submerged drydock. Water is then pumped out of the hollow drydock walls and deck to raise the vessel out of the water, allowing access to the vessel, which is completely above the water surface, as is the drydock work deck. The basin in which the business activities of JSI take place is located on the western shore of the Intercoastal Waterway. The Waterway and basin are part of an estuarine system, as these water bodies are tidally influenced. The basin and the Intercoastal Waterway constitute Class III waters of Florida. The configuration of the basin is as found in JSI Exhibit 16, an aerial photograph of the site. Moving from east to west within the basin, it is approximately one thousand feet from the Intercoastal Waterway to the back of the basin in its western-most extremity. In the back area of the basin the north- south axis is 250 feet. The interface between the basin and the Intercoastal Waterway on the eastern reach north-south axis is approximately 625 feet. There are no obstructions to the confluence of the Intercoastal Waterway and the eastern side of the repair basin. The southern-most reach of the basin is approximately 350 feet in length running east to west. On the eastern side of the basin there is a pier area which is roughly 360 feet north-south by 60 feet east-west. As described before, the pier is not a solid structure extending to the bottom of the water. Thus, water can be exchanged between the basin and the Intercoastal Waterway beneath the pier. JSI had acquired the Bellinger Shipyard in 1974. At that time environmental permits had been issued allowing for the maintenance dredging of the basin. These permits were valid through 1975. In 1975, JSI obtained a dredge and fill permit from the Florida Board of Trustees of the Internal Improvement Trust Fund, as well as a dredge and fill permit from the United States Corps of Engineers. These permits were for a ten-year period. They allowed maintenance dredging in the amount of 66,000 cubic yards per annum and for the disposal of the dredged material in an EPA-approved offshore site. In 1980 DER confirmed the dredge and fill permit that had been obtained from the Florida Board of Trustees. This permit by DER required JSI to conduct monitoring of turbidity during dredging, but did not require employment of turbidity screens. In 1979 the Army Corps had required JSI to conduct bioassay analysis in furtherance of the federal dredge and fill permit. In the face of the results obtained in that bioassay analysis, the Army Corps continued the dredge and fill permit to JSI dating from August 14, 1980. A subsequent extension of the federal permit was given through August 14, 1986. Contemporaneous with the present permit application before DER, JSI has requested further permission from the Army Corps related to the ability to excavate as much as 66,000 cubic yards of material on an annual basis. JSI has not been cited by any regulatory agency related to water quality violations associated with its dredging activity. The present DER permit application is for renewal of the 1980 Permit No. 16-21380 and is being processed under the DER File No. 161071139. This application for permit renewal was submitted on July 16, 1985. The application requests permission to maintenance dredge for a period of ten years. If granted, it is the intention of the applicant to use a closed clam shell bucket to excavate the material in the basin. This choice is in furtherance of the suggestion of DER and is a departure from the applicant's initial intention to use an open bucket to excavate. JSI also intends to employ turbidity curtains during the dredge activities. The applicant intends to transport the dredged material to the aforementioned EPA disposal site which is at sea. In doing so, a hopper barge is propelled by a towing vessel. Both the barge and towing vessel are inspected and certified by the United States Coast Guard. The crews involved in the transport of the material are qualified and licensed. In the past, transport of the material has been done under fair weather and smooth sea conditions, and it is intended that the transportation be done in that same setting if the permit is granted. The barge would not be loaded fully, thereby minimizing spillage. This was the arrangement in the past. The United States Coast Guard will be apprised of the departure time of the voyage in transport of the material, certain activities within that transport and upon return. The hopper barge has a bottom dump which is closed during transport and is opened at the bottom in disposing the dredge material. After satisfying DER about its proposal, JSI was informed that DER intended to grant the dredge permit requested. When Petitioner, George H. Hodges, Jr., the owner of real property adjacent to the site of the project, learned of the stated intention to grant the maintenance dredging permit, he offered a timely petition in opposition to the proposed agency action. This property of Petitioner is in Jacksonville, Duval County, Florida. It is located north of the JSI property at issue. Petitioner's real property is connected to the Intercoastal Waterway. Petitioner has filed this action in opposition to the grant of the permit upon the expressed belief that the dredging activity will cause pollution at his property. In particular, it is JSI's intention at various times in the calendar year to do maintenance dredging in the entire basin. In addition to using a closed clam shell bucket, a system of turbidity barriers or curtains will be employed in segmented dredge areas. Those several locations within the basin which are cordoned off with the turbidity curtains are as depicted in JSI's Exhibit 9 admitted into evidence. The design maintenance depths for the dredging project are set forth in JSI's Exhibit 4 admitted into evidence. They vary from -17 to -37.5 feet, with the greatest depth being contemplated under drydock number 1 in the northwestern corner of the basin. Near the Intercoastal Waterways the depth sought is -17 feet, transitioning to -21.5 feet moving toward the back of the basin at the western extreme and outside of the area dredged beneath drydock number 1. The depths sought under drydock numbers 2 and 3 are -26.5 feet and -20 feet respectively. These desired elevations correspond to conditions at mean low water. The tidal range in the Intercoastal Waterway adjacent to the basin, which would promote an influence in the basin proper, is in the neighborhood of 4-foot intervals, with two tidal cycles a day. This would mean, as example, that at the high tide range, the shallowest design depths for dredging of -17 feet become -21 feet in the transition from mean low water to mean high water. Those 4-foot variations would pertain to the other design depths contemplated in the dredging as described in the preceding paragraph as well. The turbidity barriers contemplated for use will extend from the surface through the water column to depths near the bottom. See JSI Exhibits 4 and 9. It is desirable, according to Dr. Gregory Powell, witness for JSI, a reliable expert in describing the effectiveness and use of turbidity curtains, to have those curtains extend to an area just above the bottom. Dr. Powell's education includes a Masters Degree in coastal and oceanographic engineering and a Ph.D. Degree in engineering mechanics, with emphasis on coastal and oceanographic engineering. In consideration of his remarks, under the influence of high tide there could be as much as a 4 foot gap between the curtain and the bottom. Powell and other experts who offered testimony agreed that turbidity screens can have effectiveness in areas of low current velocity, assuming the proper installation, maintenance and extension to a location near the bottom of the water body. If mismanaged, turbidity screens are not effective in controlling turbidity. Moreover, they are less effective in areas where significant current velocities are experienced. This would include the circumstance in which a foot and a half or more per second of flow was being experienced, according to Dr. Powell, whose opinion is accepted on this point. He also indicated that the quiescent areas in the basin, toward the back of the basin or western dimension of the basin, would show a flow regime in a rate of one centimeter per second. This expression is credited. Although, as described by Dr. Powell, the currents in the Intercoastal Waterway are moving at a rate approximating nine feet per second on ebb time at the bridge located on the Intercoastal Waterway to the south of the project site, these current velocities are not expected in the area where the dredging is occurring. Dr. Powell is correct in this assessment. As he describes, and in acceptance of that testimony, eddies from the current from the Intercoastal Waterway at peak flood tide could come into the basin and temporarily show velocities of one foot per second; however, these velocities are within the acceptable range of performance of the turbidity barrier. Dr. Powell's conclusion that wind would have no significant effect on the current velocity, given the depth of this basin, is also accepted. The remaining flow regime in the basin is not found to be a detriment to the function of the turbidity barriers. The use of turbidity curtains in this project is not found to be a "placebo" to placate DER as suggested by Erik J. Olson, engineering expert who testified in behalf of the Petitioner The monitoring that is intended in the course of the dredging activities would call for examination of background turbidity levels at three sites in the Intercoastal Waterway prior to commencing of dredging and twice daily at each of these sites during dredging. Should a violation of state water quality standards for turbidity be detected, dredging will cease until the problem with turbidity can be rectified. To provide ongoing assurances of compliance with water quality standards, JSI will analyze the sediment in the basin for the parameters of cadmium, copper, aluminum, lead, mercury, oil and grease every two years. Dr. Powell, expert in engineering and recognized as an expert in the matter of transport of the resuspended sediment associated with the dredging, as well as David Bickner, the project review specialist for DER, believe that the use of the closed clam shell bucket technique and employment of siltation screens or barriers, together with turbidity monitoring, will effectively protect against turbidity violations in the Intercoastal Waterway adjacent to the basin. This opinion is accepted. Bickner brings to his employment a Bachelor of Science degree in biology and a Master of Science degree in ecology. Bickner identified the principal concern of DER related to this project as the possibility of release of resuspended sediments into the Intercoastal Waterway. With the advent of the techniques described in the previous paragraph, only minimal changes in background conditions related to turbidity are expected. Although there would be turbidity violations within the confines of the areas where the dredging occurs, the principal influence of that turbidity will be confined in those regions. This speaks to dredge areas I, 2 and 3. According to Bickner, whose opinion is accepted, the turbidity changes within the dredge areas in relationship to background conditions do not require a mixing zone permit, nor do they constitute a basis for denial of the permit. As alluded to before, and as described by Dr. Powell, the basic nature of the basin in question is one of quiescent conditions with low current velocity. He points out that the layout of the basin is such that it is a sediment trap allowing the deposit of silt, in particular in the deeper sections of the basin near the western side. The greatest influence by resuspension of sediment in the dredging activities can be expected in the back portions of the basin and it is in this area that the silt barrier can be expected to be most efficient, based upon Powell's remarks. Dr. Powell indicated that there is the expectation of increased efficiency in turbidity control when a closed clam shell bucket is used, as opposed to the open style of clam shell bucket. Those efficiencies range from 30 to 70 per cent. There is some risk of increased turbidity near the bottom of the water column in the use of a closed clam shell bucket, and for that reason the applicant should monitor the activities of the operator of the excavation machinery to guard against inordinate disturbance of the area being excavated. On balance, the closed clam shell bucket is a superior technique to the open style of clam shell bucket excavation when those alternatives are compared. As Dr. Powell explained, the segmentation of the dredge area allows the resuspended sediment to be confined in more discrete circumstances and to be controlled. The location of the silt barriers behind the pier structure guard against the effects of eddying. The silt barriers can be properly anchored and will not be unduly influenced by current velocity. Dr. Powell believes that the use of silt barriers, taking into account a low velocity of current in the basin, and the proper deployment of the siltation screen could bring about a reduction of the resuspended solids by 80 to 90 per cent on the outside of the barrier. To calculate the influence or the environmental significance of that remaining 10 to 20 per cent of resuspended solids at the Intercoastal Waterway, Dr. Powell testified that the suspended load behind the silt curtain resulting from the dredging is expected to average from 100 milligrams per liter to a peak amount of 500 milligrams per liter. He believes that, depending on which methods of calculation is used, the dilution factor in the Intercoastal Waterway ranges from 330:1 to 600:1. In using an environmentally conservative assessment, that is 80 per cent effectiveness of the silt curtain with a 330:1 ratio, Powell calculated that the release of resuspended materials into the Intercoastal Waterway would be approximately .3 to 1.5 milligrams per liter. This translates to less than 1 NTU against background conditions. This result would not exceed the 29 NTU limit against background that is described as the standard for turbidity control. Dr. Powell's opinion of turbidity results based upon the dredge activity is accepted. There is exchange of water between the basin and the Intercoastal Waterway and to accommodate this influence, the turbidity curtains would be placed in such a fashion that they would not compete with the ebb and flow of the tide. Dr. Powell's assessment of the circumstance in describing the effectiveness of turbidity barriers takes into account the tidal conditions and the inappropriateness of trying to have the silt curtains prohibit the flow conditions during these tidal changes. In order to promote maximum effectiveness of the turbidity barriers during the entire course of excavation of materials, the length of, the silt screen must be adjusted as desired elevations are approached. Erik J. Olson is an expert in civil engineering with an emphasis on hydraulics and the holder of a Masters Degree in coastal and oceanographic engineering. As alluded to before, he questions the validity of the use of siltation barriers as an effective protection against the implications of turbidity. He properly points out that the curtains will not extend to the region of the interface of the basin and the water column at all times. He describes the exchange of water between the basin and the Intercoastal Waterway, to include the unrestricted sediment transport beneath the turbidity curtain. He believes that wind can cause changes in current velocity as great as .2 foot per second, activities within the basin an additional .3 foot per second, and eddying .3 foot per second. All of these taken together do not exceed the range of effective response of the turbidity barriers. On balance, Olson's criticism of the benefit of turbidity curtains is unconvincing. Arlynn Quinton White, Jr., who holds a Bachelor of Science Degree, a Master of Science Degree in biology and a Ph.D. in matters related to marine biology, offered his testimony in support of Petitioner. He believes that as much as 2 to 3 per cent of the resuspended sediment related to the dredging activities would reach the Intercoastal Waterway under the best of conditions. It is difficult to translate that testimony into a measurement of changes in turbidity levels against ambient conditions in the Intercoastal Waterway. In any event, as already indicated, the changes in turbidity levels are not expected to exceed 29 NTU against background. It is evident that the turbidity curtains are necessary and their proper use must be assured to protect against problems associated with turbidity and the implications of the constituents of the resuspended particulate matter related to possible toxicity. Therefore, the close monitoring suggested in the statement of intent to grant the dredge permit is viable. Another matter associated with the implications of turbidity pertains to the fact that when the dredge material has been resuspended, as much as two days could pass before the basin returns to background conditions, given the high content of silt with its attached metals. This becomes significant given the uncertainty of the location of the dredge equipment during the course of excavation, i.e., inside the barrier or outside the barrier. Final choice about the placement of the dredge equipment will have to be made at the time of the excavation. Should the dredge equipment be inside of the cordoned area while excavation is occurring, it would be necessary to allow turbidity conditions to achieve background levels before opening up the barrier for the exit of the hopper barge which contains the excavated material. Otherwise, the estimates as to the influence of the dredging activities in the Intercoastal Waterway are unduly optimistic. Likewise, if the excavation platform is placed outside of the work site, that is to say, on the outside of the siltation curtain, extreme caution must be used to avoid spillage of the excavated material when being loaded onto the hopper barge. The occasions in which the excavation is being made from this side of the barrier should be minimized. These safeguards are important because any changes in sediment loading within the Intercoastal Waterway promote an influence in the area immediately adjacent to the basin and other sites within the Intercoastal Waterway as well. The subject of the use of a hydraulic dredge as an alternative to excavation by use of a closed clam shell bucket was examined in remarks by the witnesses appearing at hearing. Olson believes that there are hydraulic dredges which can achieve the design depth contemplated by the project and which equipment could fit inside the basin area. This is contrary to the opinion of witnesses for the applicant and DER who do not believe that the hydraulic dredging equipment which would be necessary to achieve the design depths would fit into the basin area. On balance, the record does not establish that such equipment with the appropriate capability and size does exist. More importantly, the proposed method of excavation is environmentally acceptable when examined in the context of the permit sought in this case. Finally, it was not essential for the applicant to make a detailed investigation of availability of hydraulic dredging equipment and it is not determined that failure to make this investigation warrants the denial of the requested permit. Although an hydraulic dredge is more desirable from the standpoint that it causes less turbidity through resuspension of sediments, it is not the only plausible method of excavation in this instance. Raymond D. Schulze testified in behalf of JSI. He holds a Bachelor of Science Degree and a Master of Science Degree in environmental engineering sciences. In particular, he established the fact that the amount of resuspended solids that would be introduced into the Intercoastal Waterway associated with the dredging activity would not result in the smothering of organisms or to clogging of gills of fish. In addition to the possible problems with turbidity, there is the additional issue of violation of water quality standards in the several parameters associated with concentrations of metals in the water column within the basin and in the sediments or related parameters such as dissolved oxygen and biological integrity. Having considered the testimony, the facts do not point to water quality violations for any parameters occurring in the Intercoastal Waterway as a result of the dredging. To arrive at this factual impression, the testimony of Dr. Pollman and Schulze is relied upon. Water quality sampling done by JSI in locations within the basin and in the Intercoastal Waterway, that by Dr. Pollman and Schulze, supports their impression of the acceptability of the dredge activities. This water quality data was admitted as JSI's Exhibit 18. Additionally, the field conditions existing at the time of testing, to include water temperature, weather conditions, tidal cycle, ph and dissolved oxygen were also made known. This water quality data and other information examined by these witnesses points to the fact that no increases in concentrations of metals are occurring within the Intercoastal Waterway as a result of the business activities of the applicant, nor are they to be expected while dredging operations are under way. Dr. Pollman correctly identifies the fact that there will not be significant degradation of water quality, above DER's minimum standards, related to the Intercoastal Waterway based upon the dredging activities within the basin, dealing with the water quality parameters of mercury, zinc, cadmium, chromium, lead, aluminum, iron and copper, substances which are within the basin. Dr. Pollman also examined sediment data collected by DER, and that data tended to confirm his assessment of the influences of the dredging activity related to these parameters. Dr. Pollman does not believe that metal concentrations contained in the sediment of the basin are leaching into the water column in quantities sufficient to cause violation of water quality standards. His opinion is accepted. Pollman had collected water quality samples in the two locations where the greatest siltation rate was expected and as a consequence the greatest concentration of metals would be expected. The water quality samples were taken at several depths to reach an opinion as to the matter of leaching of metals into the water column and the possibility of those metals dissolving in the water column. If leaching had been occurring, a concentration of metals expressed as a gradient would be expected. The greatest concentration in this instance would be near the sediment interface with the water column. No such gradation was detected and the idea of leaching was ruled out. Bickner's testimony established that testing for the exact amount of iron present at the dredge site was not required, given the nature of the iron source being introduced into the water within the basin. Bickner did not find that type of iron to be toxic. As stated before, Pollman agrees that no violation of state water quality standards as a result of the presence of iron associated with the maintenance dredging should be expected. There is some data which shows water quality violation for mercury in the basin and the Intercoastal Waterway. Subsequent water samples collected by Schulze in the westerly portion of the basis did not show detectable levels of mercury. Moreover, data taken by Pollman and Schulze and compared with the DER sediment data shows that the concentration levels of mercury are greater in the Intercoastal Waterway than in the basin, thereby suggesting that there is no concentration gradient for mercury which would lead to the belief that the basin contributes to the amount of mercury found in the Intercoastal Waterway, nor is the mercury believed to be leaching into the water column in the basin. The explanation of the differences in measurements of the amount of mercury in the basin, depending upon the point in time at which analysis was made, may be attributable to a natural phenomenon, given numerous sources of mercury within the environment. Whatever the explanation of these changes, Dr. Pollman does not believe that the release of mercury associated with the resuspended sediments that may find their way into the Intercoastal Waterway would show a violation of the state water quality standard for mercury in that water body and his opinion is credited. Data collected by Pollman and Schulze did not show water quality violations for aluminum and the DER test data described before indicated aluminum levels lower in the basin than in the Intercoastal Waterway. Some data collected by Technical Services, Inc., an environmental consulting firm in Jacksonville, Florida, which was reviewed by Pollman, Schulze, and Bickner showed a substantial violation of the water quality standard related to aluminum in sediment sampling that was done. The origin of that amount of aluminum found on that occasion was not clear. It is possible, as described by Bickner, Pollman and Schulze, that the level detected In the Technical Service report could have occurred based upon natural phenomena such as storm water runoff from uplands. Bickner also questioned the findings of Technical Service and felt like the determination might be influenced by some intervening circumstance which would promote the need for re-analyzing that parameter. Whatever the explanation of the findings in the Technical Service report, it does not point to any water quality violation of the standard related to aluminum based upon the dredging activities, given the limited amount of total suspended solids that would be introduced into the Intercoastal Waterway. Schulze, in his assessment of the implications of metal concentrations in the sediment transported to the Intercoastal Waterway, did not find them to cause concern about toxicity to marine life in the Intercoastal Waterway. This point of view is accepted. In trying to understand the implications of metal concentrations, Schulze believed that the biologically available fractions of those metals in the sediment is not very high, and when the dilution of the sediments which occurs in these circumstances is examined, no toxicity is expected. Moreover, as Dr. Pollman described related to the parameter aluminum, it is not a toxic material at the ph levels found in the basin, and the resuspension during dredging will not cause it to gain toxicity. This opinion of Dr. Pollman is supported by Bickner and Schulze. The opinion of Dr. White that the amount of aluminum, copper and zinc within the sediment found in the basin would eventuate in the violation of water quality standards for those parameters when introduced into the Intercoastal Waterway is rejected. The information available to Pollman, Schulze and Bickner which describes their opinion about water quality standards was sufficient to reach an opinion, the position of Petitioner's witness Sanford Young, holder of a Bachelor of Science Degree in civil engineering and a Master of Science Degree in zoology notwithstanding. As Bickner indicated in his testimony, it is essential that an applicant give reasonable assurances of compliance with all parameters listed in Chapter 17-3, Florida Administrative Code, dealing with water quality. However, this does not mean that testing must be done for each parameter set forth in that chapter. Reasonable assurance has been given that water quality parameters as identified in that chapter will not be violated. Bickner indicates the biological integrity standard is not one of concern in that given the nature of business operations within the basin, there is no expectation of a stable benthic community which might be disturbed by dredging. From the remarks of Schulze, there is no prospect of danger to benthic communities within the Intercoastal Waterway. These impressions by Bickner and Schulze are accepted. Under the facts of the case, the failure of the DER permit appraisers to discover benthic organisms in the sample grabbed at the site is not unexpected. There is also some question about whether that sample is representative of the circumstance at the site, given the limited sampling. On the topic of normalization of the DER data which was described in the course of the hearing and is identified by Dr. Pollman, the value of that information is seen as establishing the relative quantities of certain metals within the basin as compared with other sites throughout the Intercoastal Waterway. Twenty-one different locations were involved in this analysis. Concentration ratios using aluminum to normalize the data are as reflected in JSI's Exhibit 17 admitted into evidence. The significance of this information as it grossly describes whether the basin routinely contributes to increases in the amounts of these metals within the Intercoastal Waterway. Overall, basin activities are not shown to have promoted such an outcome. This normalization comparison does not address the issue of site specific water quality violations; however, no such violations are expected associated with the dredging activities within the basin as it relates to violations in the adjacent Intercoastal Waterway. Schulze had made sampling related to dissolved oxygen within the basin and the Intercoastal Waterway. As Schulze describes, the levels of dissolved oxygen seem to be at their lowest point just prior to the dawn hours. Sampling which he did was done at 5:00 a.m. in order to obtain the lowest dissolved oxygen readings. Three sites were sampled within the basin and an additional site was sampled in the Intercoastal Waterway. Readings were taken at varying depths at each site to gain an impression of the overall water column. The mean reading for the circumstance was in excess of the required range for state water quality, that is 4.0 per million. Having considered the evidence, no problems with dissolved oxygen are expected in that deficit contribution is in the range of .1 milligram per liter, per Pollman. In addition, Dr. Powell, through modeling, examined the implications of long-term dredging activities on the topic of dissolved oxygen. He employed field data gathered by Schulze in this assessment. This modeling established that decreases in dissolved oxygen levels would range from .1 to .15 milligrams per liter. Given the average of 4.5 parts per million oxygen in the basin at present, the incremental decreases in dissolved oxygen levels related to the dredging would not pose a problems with state water quality standards for dissolved oxygen other than short-term effects in the immediate vicinity of the dredge area, which is an acceptable deviation. As the Petitioner urges in its fact proposal, a 1983 report of Technical Services, Inc., JSI Exhibit 4, and a 1985 report of that firm, JSI Exhibit 7, were made available as part of the application. Officials within Technical Services, Inc. did not appear at the hearing and offer testimony related to the specific findings found in those reports. This information was used by the experts who did testify on behalf of the applicant, in particular Dr. Pollman, as data to question, his assumptions made about the implications of the project in terms of water quality concerns. Pollman also utilized DER data taken from a source known as Storette, and this pertains to the 21 sampling stations involved in the preparation of JSI Exhibit 17, the graphing document related to concentrations of various metals. Again, this was in furtherance of the basic underlying opinion which Pollman had about the project. The Storette data as such was not offered into evidence. Witnesses for the Petitioner, namely Olson and White, were aware of the two reports of Technical Services, Inc. and the use of the DER Storette data and offered their criticism of the project taking into account this information. Petitioner points out that there is no indication as to how far below the sediment/water interface the Technical Services, Inc., and DER sediment samples related to reports of the consultant and the Storette information of DER were extracted. Therefore, it only reflected one portion of the sediment at a depth of extraction. A more complete understanding of the sediment characteristics would have been shown through a core sample, especially in the area to be dredged, but that understanding was not essential. The suggestion by the Petitioner that it was inappropriate to normalize data for purposes of describing the relative concentrations of the metals parameters is not accepted. The preparation of JSI's Exhibit 17 does not point to abnormally high amounts of aluminum, such that the use of aluminum as a known commodity in carrying out the normalization would be contraindicated. As identified by the petitioner in its proposal, sediment sizes within the strata found in the basin depicts higher percentage of silt and clay-size sediments in the back end of the basin with lesser amounts of the silt- and clay-size sediments in the southern reach of the basin and at the intersection of the basin with the Intercoastal Waterway. The smaller the particles, such as silt and clay, will remain suspended for a longer period of time and have a tendency to promote bonding with heavy metal. Nonetheless, this information does not change the impression that the turbidity barriers will be effective. The 1983 Technical Services, Inc., information related to the settling of resuspended sediment and similar information imparted in the 1985 report by that organization tend to confirm that approximately two days should be necessary to allow the area of excavation to return to background conditions related to turbidity. This is in corroboration of remarks by Dr. Powell. These time projections are not found to be inadequate when taking into account other factors such as tidal changes, boat traffic, other activities within the basin, wind and weather events. As White described, the antifouling properties of the paint involved in the business activity of the applicant can be expected to adversely impact any larval forms of marine organisms when introduced into the basin. Nonetheless, this toxicity is not expected to pose a danger to marine organisms in the Intercoastal Waterway given the percentage of resuspended sediment that will escape capture by the sediment barriers and the dilution factor before introduction of those resuspended sediments into the Intercoastal Waterway. Petitioner questions the acceptability of evidence of the findings set forth by E G & G Bionomics, a firm which performed an examination to determine existing diversity of benthic macroinvertebrates. Those results are reported in Petitioner's Exhibit 13, a 1980 report. They were not accepted as evidence of the specific findings within that report in that they were not the subject of discussion by persons who authored that report. The use was limited to corroboration of the opinion by Dr. Pollman and Schulze as to water quality considerations and they were not Crucial to their opinions. Moreover, it was not necessary for the applicant to perform a more recent bioassay in order to give reasonable assurance to DER concerning water quality matters or to establish the implications of the influence of contaminants within the sediment found in the basin related to benthic macroinvertebrates. The biological integrity of the basin area was at risk prior to the proposal for maintenance dredging. The relevant inquiry is the influence of the dredging activities on the biological integrity in the Intercoastal Waterway and those activities do not place organisms within the Intercoastal Waterway in peril. Any synergistic aspects of metals which act as toxins, for example, the increase in the aggregate value of the toxicity of zinc and cadmium, compared to their individual implications as toxins, will not present problems with water quality in the Intercoastal Waterway. Petitioner takes issue with the proposed disposition of the dredge material at an ocean site. While an appropriate upland disposal site would be preferred, it is not mandated. The approved EPA disposal site within federal jurisdiction is acceptable. Petitioner in its fact proposals found at paragraphs 36-39 (incorporated by this reference) points out violations of water quality standards for cadmium, mercury, and aluminum, and other possible violations of the standard for mercury. This information does not cause a change of opinion about the acceptability of the project in terms of reasonable assurances. There is no indication that oils and greases will present a problem related to water quality standards. The project is not contrary to public interest in that: (a) the project will not adversely affect the public health, safety, welfare or the property of others; (b) the project will not adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitat; (c) the project will not adversely affect navigation or the flow of water or cause harmful erosion of shoaling; (d) the project will not adversely affect the fishing or recreational values or marine productivity in the vicinity of the project; (e) the project will be of a temporary nature; (f) the project will not adversely affect significant historical and archaeological resources under the provisions of s. 267.061; (g) the project is in no other way contrary to the public interest. The purpose of this fact finding does not include the issue of whether there are ongoing violations of state water quality standards associated with the business activity of the applicant, that not being the subject of the hearing. In any event, the testimony of Dr. Pollman established that the operations of JSI are not causing water quality problems associated with the parameters of cadmium, copper, aluminum, mercury, lead, chromium, tin, zinc or iron related to the Intercoastal Waterway. The influences of the business activities associated with those parameters within the basin are not understood when the evidence presented is examined but are not found to be essential to the resolution of this dispute.
Recommendation Having considered the facts, and the conclusions of law, it is, RECOMMENDED: That DER issue a final order which grants the requested maintenance dredging permit in keeping with the safeguards described in the fact finding of this recommended order.
