The permittee shall begin construction of this upgraded facility within sixty (60) days of the thirty (30) day average exceedance of 80 percent of the design capacity of the plant currently in operation. Eighty (80) percent of the design capacity is 40,000 gpd, therefore, 83 bedrooms at 120 gallons/bedroom is the allowable connections to be made once 40,000 gpd is reached. Any additional connections made to this facility will be a violation of North Carolina General Statute 143-215.1 and is enforceable by the Environmental Management Commission. 52. Within 90 days of receipt of this permit and prior to any increase in the wastewater flow rate beyond 50,000 gpd, the permittee shall submit a hydrogeologic report, based on site specific data and utilizing computer modeling or predictive calculations, demonstrating that the facility will function properly with the existing ponds which interconnect to form a line sink. This evaluation shall be conducted without the ponds constructed after September, 1989 or any proposed addtional ponds that have not been constructed. This report will then be evaluated and the permittee advised of any further actions and /or alternate wastewater disposal options that must be investigated or pursued. Please be advised that issuance of this permit does not relieve the permittee of any responsibility of enforcement for construction of any additional ponds without appropriate approval at this site. Representatives of Kinnekeet Partners were advised in the meeting of September 29, 1989 by Ms. Debra Sawyer of the Washington Regional Office that construction in and/or excavation of wetlands could not be continued - Permit issued this the 5th day of February, 1990 N04TH CAROLINA ENVIRONMENTAL MANAGEMENT COMMISSION George T.

Vegetation Report: Evaporation and transpiration from plant communities is frequently termed evapotranspiration, to describe the combined plant- soil nature of the evaporating surface. Evaporation from soil and transpiration from plants involve basically similar processes, and soil and plants may be thought of as alternative paths through which water moves on its way to the surface, from which it finally diffuses into the bulk air. Under field conditions leaves vary widely in size and in orientation with respect to heat energy and air movement. Moreover, on any one plant and in any plant community there is a vast array of leaves of different ages and structure, located in a range of microenvironments. The leaf area of stands of plants is often three to six times the area of the land on which the plants grow (leaf - area index of 3 to 6). As most leaves lose water from both surfaces, the total external area should be regarded as twice that amount. Therefore, evaporation from a plant community never exceeds that from a similar area of wet soil or water with the same exposure. RUSSNOW. KANE & ANDREWS, INC. There is a complex interaction among the factors affecting the rate of transpiration. The chief environmental factors are light intensity, vapor pressure and temperature of the air, wind and water supply to the root. Plant factors include the extent and efficiency of the root system as an absorbing surface, leaf area, leaf arrangement and structure, and stomatal behavior. If any one of these factors is altered enough to cause a change in rate of transpiration, other factors will be changed, causing further adjustments in the transpiration rate. In this study one of the plant species that will be recommended for planting around the rotary distributors will be Southern Wax Myrtle (Myrica cerifera). An average four foot tall wax myrtle has an approximate leaf and twig surface area of 50 square ft. With a documented transpiration rate of 10.8 grams of water per square decimate of leaf surface per day (G/DM2), which translates to 10.8 grams of water per 0.11 square feet of leaf surface per day. The total uptake would be: 10.8 grams * DM * 50 ft2 * 0.3527 Oz. DM2 .11ft2 1 lgram = 1731.44 oz. 128 oz./gallon 13.52 GALLONS / DAY / PLANT RUSSNOW. KANE & ANDREWS, INC. With approximately 280,000 sq.ft. of plantable area available planting 0 5 foot on center, (each plant has approximately 25 square feet of planting area) 11,200 plants will be needed transpiring about 151,000 gallons of water per day., Taking into account the nature of the coastal plain environment i.e., high amounts of radiation and steady winds this figure seems conservative from March to November. The wax myrtle would be the ideal plant for this environment. Transplanted as a balled and burlapped or as a container plant the wax myrtle thrives in poor, sterile, sandy soil as. well as in heavy clay soil. It is fully adaptable in its soil types as well as its location in full sun to half -shade. This is a beautiful, rather wispy broadleaf evergreen that will grow 10 to 15 feet high and wide and is very tolerant of salt spray as evidenced by its natural proximity to the sea. As the wax myrtle grows, it could be thinned by removal and planting around the project or off site. Signature: F Title: Date: �AA`/
