EXISTING FACILITIES: CITRUS GROVE: Presently, the proposed 604.5 acre citrus grove site, located in north central Okeechobee County, consists of approximately 340 acres of improved pasture, 115 acres of native/transitional grasslands, 23 acres of palmetto prairie, 47 acres of oak ha11111ock, and 78 acres of freshwater marsh. Lands to the east and south of this project are dominated by improved pasture for cattle grazing or dairy cattle. The project is adjacent to the southern boundary of the National Audubon Society's (NAS) Kissimmee Prairie Sanctuary, which is approximately 7500 acres of palmetto prairie, hamocks, wet prairies and deeper marshes. The project is separated from the Kissi11111ee Prairie Sanctuary by an old military grade that runs east to west along the . boundaries of both properties. A portion of the Sanctuary was acquired by the National Audubon Society from the applicant. Subsequently in 1984, a Reciprocal Water Use and Drainage Agreement was created between the applicant and th~ National Audubon Society, which stated that risers be installed on three culverts -which historically drained portions of the Kissinunee Prairie Sanctuary into Fish Slough (via this project) through the military grade. The existing culverts and risers, have deteriorated and currently allow small amounts of .flow to occur from the Sanctuary south, through this project, to the Fish Slough ditch. Fish Slough runs from northwest to southeast along the southern boundary of the Haynes Williams property (refer to Exhibit No. 4). Fish Slo~gh is a major tributary of Cypress Slough, which converges approximately .11 miles to the south with Ash Slough, to form Chandler Slough, . a major tributary to the Kissimmee River. Historically, Fish Slough consisted of a mosaic of marshes which flowed southeast to the Kissimee River. Past channelization of Fish Slough has altered the hydroperiod of adjacent marshes by facilitating runoff into the channel, and by providing a conveyance route off-site. SHELL MINING OPERATION: The proposed mining site consists primarily of improved pasture and has been used for cattle grazing. The mining site contains a previously permitted 1.92 acre mine and an existing detention area that was completed. Lands located in the vicinity of the mining operation are primarily improved pasture for cattle grazing. z ' I . I

PROPOSED FACILITIES: CITRUS GROVE: Proposed is the Construction and Operation of a surface water management system to serve a 604.5 acre agricultural project, whic~ includes 361.2 acres of citrus. The proposed citrus grove is to consist of four basins (One thru Four). Storm water runoff is pumped into two reservoirs (referred to as Detention Areas "A" and "B") that gravity discharge into Fish Slough located on the west boundary of the grove. Basin One (1), which is 36.6 acres, is proposed to be controlled at elevation 64.0' NGVD via three secondary control structures (SCS's l, 2, and 3). These three secondary control structures are to consist of 1.5' wide semicircular weirs with a crest at elevation 66.0' NGYD, rectangular bleeders 0.8' wide by 2.0' high with inverts at elevation 64.0' NGVD, and 40 LF of 18" diameter CMP culverts discharging into Basin Four (4). Basin Two (2), which is 51.4 acres, is also proposed to be controlled at elevation 64.0' NGVD utilizing three secondary control structures (SCS's 4, 5, and 6). These secondary control structures are to consist of 2.0' wide semicircular weirs with a crest at elevation 66.0' NGVD, 1.8' wide by 2.0' high rectangular bleeders with invert elevations at 64.0' NGVD, and 40 LF of 24" diameter CMP culverts discharging into Basin Four (4). Basin Three (3), which is 5.7 acres located at the southern most part of this proposed project, is proposed to be controlled at elevation 64.0' NGVD using one secondary control structure (SCS number 7). Secondary control structure number 7 is to consist of a 1.5' wide semicircular weir with a crest at elevation 66.0' NGVD, a 0.5 foot wide by 2.'0' high rectangular bleeder with an invert at elevation 64.0' NGVD, and 40 LF of 15" dia1111ter CMP culvert discharging into Basin Four (4). Basin Four (4), which is . 311.2 acres, is proposed to collect surface water runoff from the other basins for pulllf)ing into the detention system. Basin Four (4) has a control elevation, controlled by the pump system off-elevation, of 62.0' NGVD. The proposed pump system is to consist of one 12,000 gpm pump located on the west side of the detention system (into Detention Area "A") and a 9,000 gpm pump located on the east side pf the detention system (into Detention Area "B"). Both pumps have an on-elevation of 62.5' NGVD and an off-elevation of 62.0' NGVD. The detention system consists of two reservoirs, "A" arid "B" (48.4 and 71.5 acres, respectively), that are connected by. a gravity . structure. Detention Area "A" is controlled at elevation 68.5' NGVD by control structure number two (refer to Exhibit No. 5). Control structure number two (2) is a gravity structure consisting of a 3.0' wide semicircular weir with a crest at elevation 71.0' NGVD, a 0.4' wide by 2. _ 5' high rectangular bleeder with a crest at elevation 68.5' NGVD, and 60 If af 36" dia1111ter CMP culvert discharging into Detenti !on Area "B". Detention Area •e• is controlled at "eilvatlon 6/.5' NGVD by 1 ccinol structure numberone (1), which is the final 3

PAGE 4

outfall for the project. Control structure number 1 consists of a Z.O' wide semicircular weir with a crest at elevation 69.5' NGVD, a 1.4' wide by Z.O' high rectangular bleeder with an invert at elevation 67.5' NGVD, and 120 LF of 24" diameter CMP culvert discharging to Fish Slough. The emergency overflow structure serving the reservoir system is located on the east side of Detention Area •e• and consi'sts of a 4.5' diameter drop inlet with a crest at elevation 70.0' NGVD discharging back to Basin Four. SHELL MINING OPERATION: The proposed mining operation is proposed to be undertaken in four phases. Phase 1 excavation will be approximately 4.17 acres in size (approximately 20.0 feet deep). Phase 1 will be dewatered with a 1500 GPM pump (Thompson 6 HT 287 centrifugal pump) . into the 6.41 acre Phase 2 land area for retention. Phase 2 will serve as the wetretention area for Phase 1 construction. Overflow structures will be installed to allow overflow {via two. structures) during extreme rainfall events. The overflow structures will consist of 1.25' wide weirs with crest elevations at 71.7' NGVD and 40 LF of 15" CAP culverts with invert elevations at 67.0' NGVD which tie into recharge swales around the perimeter of the site. A water level of 69;0' NGVD shall be maintained within the perimeter dispersion swales (refer to Special Conditiqn No. 33). Phase 2 mining, which is 6.41 acres in size, will co•ence at the completion of Phase 1 and will utilize Phase l's excavation for wet retention. Phase 3, which is 6.5 acres in size, will utilize both Phase 1 l 2's excavations for retention (culvert connection between 1 l 2 will be provided). Phase 4, which is 6.86 acr.es in size, will utilize Phase 1, Z l l's excavations for retention (culvert connectiqn between Phases 2 & 3 will be added). Dispersion swales are utilized to discourage drawdown impacts on adjacent wetland areas. Overflow i . s to adjacent wetlands that tie into the Fish Slough system which eventually discharges into the Kissi11111ee Rher. The applicant will construct the retention area (Phase 2) prior to any excavation of Phase 1 or overburden removal. An area will be set aside for the storage of the overburde~ material that contains, around the permimeter, a perimeter swale system which will allow treatment of runoff prior to any offsite discharge. Following the completion of the mining activity, the excavations will be filled with the stored overburden material to a 4:1 sideslope to two feet below the control elevation and will remain as lakes (refer to Exhibit No. 9).

---. ----------------III. PROJECT EVALUATION Di$charge Rate: The property currently has a system of internal ditches which route storm water runoff from the site to Fish slough. Fish slough is a major receiving body for this area ~nd during major storm events its.ability to accept gravity discharge is poor. This project proposes a minimal discharge of 5.0 cfs during the 25 year-3 day event. The 25 year-3 day stage in reservoir •e• is 68.6' NGVD. Design Storm Frequency: 25 YR-3 DAY Design Rainfall: 6.00 inches WATER QUALITY: CITRUS GROVE: The proposed citrus grove is providing d tention in excess of 1.0• over the project area, within the reservoir system (•A• I •a•) prior to off-site discharge to Fish Slough. SHELL MINING OPERATION: The mining site will provide water quility treat11ent within the unused cells prior to overflowing to the dispersion swales on the east and west sides of the site. Turbidity will be the primary water quality problem associated with the construction of this project. Turbidity fr011 the mining activity will be controlled by utilizing the detention basins for water quality treatment. Turbidity from the overburden mater1al will be controlled by a swale that surrounds the area were the overburden will be located. This swale will function to reduce turbidity prior to discharging into the low areas surrounding the project site.

ENVIRONMENTAL: The project sites are located in northern Okeechobee County, just south of the National Audubon Society's Kissi11111ee Prairie Sanctuary. Several upland vegetation co11111unity types exist within .the proposed citrus project boundaries including improved pasture, transitional grassland, . palmetto prairie, and o ak ha11111ock. Four wetland conwnunity types are found on-site including: 1) freshwater marsh, which is dominated by maidencane, pickerelweed, sawgrass, smartweed, and beakrush; 2) wet prairie systems typified by St. John's wort, beakrush, panic grass, and other grasses and sedges; 3) mixed forested wetland characterized by a canopy of maple, laurel oak, and bay, with wax myrtle, ferns, and sawgrass in the understory; .and 4) sawgrass marshes." The tot a 1 wetland acreage of all co11111unity types within the proposed citrus grove is 77.21 acres (see Exhibit #11). Similar upland and wetland co11111unity types exist adjacent to the proposed shell pit location, in addition to an existing reservoir and pit-that was constructed as part of a previous short tem-mining pemit. The proposed location for the four phase shell mining operation is currently improved pasture, with freshwater .marshand wet prairie . wetlands nearby {see Exhibit #3). Wetlands range from good to poor condition at both the proposed mining operation and citrus grove location. Those wetlands in poor and fair condition have been hydrologically impacted as a result of past agricultural practices including drainage improvements, and physically impacted by mowing and reseeding for cattle grazing. Those wetlands considered to be in good condition tend to have good quality central cores with some minor disturbance of the outer transitional areas and wetland edges. CITRUS GROVE: Approximately 21.5 acres of wetlands will be protected outside the limits of the grove development area. Each of these wetlands have been provided with a 200 foot setback from all proposed excavations and grove development areas. The applicant proposes to protect an additional 38.24 acres of wetland habitat within the reservoir system. The project as proposed will impact 14.54 acres . of various quality freshwater marsh wetlands and 2.93 acres of a mixed forested wetland {see Exhibit IS). The 111ajority of the wetlands proposed for impact are of poor quality or could not feasibly be incoporated into the reservoir system. Approximately 0.47 acres of the 14.54 acres of freshwater marsh consists of one. small wetland. According. to Appendix 7 criteria, wetlands less than 0.5 acres \in size can be impacted without mitigation, provided that the wetlands are not utilized by endangered, threatened, or species of special concern. According to the applicant's submitted information, utilization of this wetland by endangered, thteatened, or species of special concern was not evident throughout the environmental evaluation. Alternative designs were evaluated by: the permittee. The current proposal inlcudes a system designed to accomodate wetland and u pland preservation. The proposed detention areas are larger than the minimum size required for 8

PAGE 9

stormwater and water quality management:These detention areas have been designed to maintain and improve wetland-upland ecosystem values on the site through incorporation of existing wetlands and an oak ha11111ock area. The project is adjacent to the southern boundary of the National Audubon Society's {NAS} Kissimmee Prairie Sanctuary, which is approximately 7500 acres of palmetto prairie, hammocks, wet prairies and deeper marshes (see Exhibit #2 for location}. The project is separated fr011 the Kissinnee Prairie Sanctuary by an old military grade that runs east to west along the boundaries of both properties. A portion of the Sanctuary was acquired by the National Audubon Society from the applicant. Subsequently in 1984, a Reciprocal Water Use and Drainage Agreement was created between the applicant and the National Audubon Society, which stated that risers be installed on three culverts which historically drained portions of the Kissi11111ee Prairie Sanctuary into Fish Slough (via this project} through the military grade. The existing culverts and risers, have deteribrated and currently allow small amounts of flow to occur from the Sanctuary south, through this project, to the Fish Slough ditch. The military grade tends to hold water in the Sanctuary at a higher elevation than the water table in the project site. Soil borings near the military grade indicate that natural ground elevation is approximately 69.0' NGVD. The water table elevation at the northern end of the proposed project was measured by District staff at 66.5' NGVD in April of 1992. The surface water level in the Sanctuary was measured at 67.5' NGVD at the same time. The project as currently designed provides for a setback of 200' between the existing military grade and all proposed grove. construction. No citrus production, excavation or other associated activities will occur within th~ setback area. In addition to th~ 200' setback, • seepage analysis was submitted to determine the effect of the grove operation on the adjacent wetlands in the Kissimee Prairie Sanctuary. The proposed control elevations for the developed grove in the northern basins are 64.0' NGVD. The gradient created between the developed grove area and the Sanctuary will be approximately 3.5'. The 200' setback between the northern edge of the project and the military grade reduces the flow gradient that would occur if the setback was not provided. In addition, detention area A, which abutts the Sanctuary, will be controlled at an elevation of 68.5' NGVD. which should further reduce the gradient. Information submitted by the applicant indicates that the proposed rate of seepage, based on a field determination of the hydraulic conductivity, would be approximately 0.77 cfs across the length of the military grade (5000'). For a 90-day no rainfall condition, the 0.77 cfs seepage rate would impact the 7500 acre sanctuary by less that one quarter of an. inch. T~o Special Conditions are included requiring surface and groundwater m~nitoring to evaluate the effect of the developed project on water levels in the Kissimmee Prairie Sanctuary. Water level readings in the swale on the south side of the military grade ar~ . required, pursuant to Special Condition #38, at each of the three culverts. A surficial aquifer observation well is also required within the 200' setback area between the proposed grove and the military grade (see Special Condition i 9

PAGE 10

#39). Data collected is required to be submitted to Audubon Research Center and the District on a semi-annual basis. Monitoring will continue for a period of five years. Several species of wildlife were encountered on the project, including sandhill cranes, deer, caracara, wood storks, and herons. In addition, the applicant submitted a wildlife survey which included kestrels, alligators, limpkins, and snowy egrets. Prior to construction, the applicant will be required to survey for wetland-dependent species nesting activity. Should any of the wetlands be found to support wetland-dependent species nests or any other endangered, threatened, or species of special concern, the applicant will be required to temporarily discontinue construction until such time that the young have fledged (see : Special Condition #36). An abandoned caracara nest was observed in a portion of the site that contained scattered cabbage palm trees. Due to the project's location, south of the Kissin111ee Prairie Sanctuary; wildlife may travel back and forth from the preserve. In addition, the Florida Game and Fresh Water Fish Connission has requested that the permittee maintain a 200 meter buffer between any heavy equipment operation or construction, if an active caracara nest is observed (see Special Condition #37). It will be the applicant's responsibility to coordinate with the Florida Game and Fresh Water Fish Co11111ission and/or the U.S. Fish and Wildlife Service for appropriate guidance, reco11111endations and/or necessary permits to avoid impacts to listed species during construction and operation (see Special Condition #31). To offset the proposed 17.0 acres of impacts to wetlands larger than 0.5 acres, the applicant will create 21.7 acres (21.7 acres 9 1.5:1 ratio• 14.5 acres of credit) of wetland habitat within the surface water management reservoirs in areas that are currently transitional grasslands (see Exhibit #5 for location). The grassland areas, defined by the applicant as low prairies of carpet grass, coinwort, broomsedge, low panicum, tumble grass, buttonweed, and heliotrope, were probably wet prairie systems prior to the drainage . improvements created to provide cattle grazing opportunities. By providing the necessary inundation levels and hydroperiods indicative of the local wetland systems, the grassland areas should revert to historic wet prairie habitat. Control elevations have been set -at 6~.5' NGVD i~ the north detention ~rea (A) and 67.5'NGVD in the southern detention area (8)~ Wetland elevations, based on submitted topographic infomation, are approximately 1.0 to 1.5' below the control elevations, effectively allowing for the restoration of the degraded wetlands to occur and providing the necessary -inundation levels required for wetland creation. In addition to the creation of wetland habitat, the applicant will set aside as upland compensation 11.8 acres of oak hannock within the southern detention area (11.8 acres@ 3:1 ratio• 3.93 acres credit) (see Exhibit #5 for location). The oak ha11111ock is in good condition • as it h as not been heavily damaged by cattle grazing. It consists of live oak and cabbage palms and occassional laurel oaks. The lowest ground elevation in the ha11111ock is 68.0' NGVD. Based on the applicant's submitted routing information, the peak stage in the southern detention area for a 25 year, 3 day storm event is 68.56' 10

PAGE 11

NGVD, and the area will require approximately 7 days to return to a pre-event elevation. Impacts to the hammock due to altered levels of inundation in the southern detention basin are not anticipated. A wetland monitoring program will be implemented in accordance with Special Condition #27 and Exhibits 12A, 128, and 13. This plan includes three vegetation transects which bisect the existing wetlands, the created wetland areas, and the upland preservation area within the two detention basins. Panoramic photographs, staff and rain gauges are also required. Monitoring reports will be submitted to the District' on an annual basis for five years. SHELL MINING OPERATION: The shell mining operation is proposed on the western portion Qf the permittee's property. The four phase operation is setback 200' from the adjacent wetlands including Company Slough. In addition to the setback, the applicant has designed a recharge ditch or dispersion swale around the edge of the four phased shell pit to provide a constant head or hydraulic barrier, between the pit and the adjacent wetland systems {see Exhibit #8). The swale will be constructed for phases 1, 2 and 3 in conjunction . with the construction of phase 1 and 2, and then will be expanded with phase 4 of the shell pit. The water levels in the swale will be maintained at 69.0' NGVD, an elevation that corresponds to the adjacent wetland rim elevations {see Special Condition #33). Following completion of the shell pit, the permittee will contour _ the side slopes and replace the overburden along the banks of the pit. Final side slopes wi)l be in accordance with Special Condition IS. A water level monitoring program will be implemented in accordance with requirements of the concurrent mining/dewatering application and Exhibits 14A and 148. Three wells will be installed in conjuction with phase 1 to monitor: 1) if the dispersion swale: operates as permitted; 2) if a positive gradient was created between the wetlands and the mining pit by maintaining the constant headin the dispersion swale; and 3) to estimate the areal extent of potential drawdowns created by the dewatering operation. During 'each of phases 2, 3, and 4, a well will be installed to monitor ground water elevations adjacent to the active dewatering pit. In addition to the six wells, si~ staff guages will be installed to monitor surface water levels: three in adjacent wetlands, two in the dispersion swale, and one in the active dewatered pit (see Exhibits 14A and 148). 11
