Important SOC, JOC or Compliance Schedule dates (please indicate): N/A Date Submission of Plans and Specifications N/A Begin Construction N/A Complete Construction N/A PART III - OTHER PERTINENT INFORMATION (continued) 4. Other Special Items: Soils Information: The site was also investigated on the same day by Mr. Vincent Lewis, Soil Scientist, Division of Soil and Water, Wilmington Regional Office. The 'soils evaluated were the Wagram series with water table greater than 48 inches. Mr. Lewis indicated that the soil could take greater than 2 inches / acre / week but gave a conservative rate of 1.75 inch / acre / week. Land Use: All land is owned by Lake Creek Corporation. The site was previously pine forest which has been cleared, grubbed and sprigged with Coastal Bermuda grass. Description of Proposed System: The subject facility is a resort communitywhich has a year round population of approximately 63 customers ,(75%). There are 84 lots including a fire station and the Lake Creek Corporation office complex. The domestic wastewater from this resort flows to the existing WWT Plant and discharges into Colly Creek. The proposed modifications to this system is to basically utilize 'the same system, expand it by 20,000 gpd and discharge into the existing waste stabilization lagoon which will now have a 30 day storage volume. The wastewater will then flow from the lagoon to a chlorine contact chamber and spray irrigated onto a 5.08 acre Coastal Bermuda field. Land Limiting Constituent Analysis: Assuming a 40,000 gpd flow rate, the annual flow to this facility would be 14,600,000 gallons. Utilizing the nutrient analysis provided in the package, the PAN concentration is 3.192 mg/l. This equates to 1.06 lbs PAN / per 40,000 gallons of wastewater or 388.7 1b PAN per year. Thus, PAN is not a limiting factor. All metalsand phosphorous are not limiting. The calculated SAR is 1.26. It appears that the limiting constituent is hydraulics. The soils scientist's report provided in the package by Land Management Group, Inc., of Wilmington, North Carolina, modeled two design flows of 30,000 gpd and 60,000 gpd. Both models were based on a 200,000 sq. ft. area (4.59 acres) assuming a continuous 200 day wet season with no evaptranspirational effects. The projected flow over the next decade is not anticipated to exceed 40,000 gpd. Based on the 60,000 gpd model, the 200,000 sq. ft. area (4.59 acres) can assimilate the water volume if proper management of spray facility is implemented. This model was also performed on the wet portion of the spray acreage. The soil type, as previously stated, is the Wagram series which is well drained deep sands in the Coastal Plain area of North Carolina. Mr. Lewis indicated in his evaluation that this soil could take much more than a 2 in. / acre / week hydraulic rate. As previously stated, the annual calculated volume based on a 40,000 gpd flow rate is 14,600,000 gallons. This equates to 105.8 in / acre / yr. Assuming a 52 week year, this calculates to PART III - OTHER PERTINENT INFORMATION (continued) , be 2.03 in / acre / week. This is not taking into ,consideration wet weeks when spraying is not possible or the facility's storage capabilities. This is within recommendations by the soil scientist (Land Management Group, Inc.) provided in the land application package and Mr. Vince Lewis' recommendations. From a hydrological standpoint, this acreage can handle the projected flow rate. Also, adjacent land is available should future expansion be necessary. Also due to the low nutrient content of this wastewater, it is recommended that the residuals be allowed to be land applied on the same acreage to reduce commercial fertilizer costs to maintain a healthy crop. Crop Management Plan: The crop, as previously stated, is Coastal Bermuda grass. j' The effluent will be spray irrigated onto the acreage and the. nutrients, of this effluent wastewater, will be agronomically applied. Other nutrient supplements will be the responsibility of Lake Creek Corporation. Records Management: i' All records will be the responsibility of Lake Creek Corporation. Accessibility: Access is controlled by fences and gates. All land area is owned by Lake Creek Corporation. PART IV - EVALUATION AND RECOMMENDATIONS It is the recommendation that the subject application be processed and the; appropriate Permit issued. The existing NPDES Permit cannot consistently meet final effluent parameters and the proposed spray system should be better for the environment and give this facility more flexibility.

There is potential for the sludge basin to contaminate ground water, however the basin is located near a wetland discharge which minimizes the impact of any contamination. No supply wells are located in the path of the potential contaminant plume. We did not receive a laboratory analysis for the sludge hutcontaminant concentrations are typically higher in sludge than in waste water. Therefore groundwater monitoring is recommended as a precautionary measure. Issue the permit ` -Zo6. Hya.
