REGAN senrm,'r LINDA CULPEPPER Diao, NORTH CAROLINA Environmental Quality March 5, 2019 CERTIFIED MAIL, 7016 2140 0000 43710851 RETURN RECEIPT REQUESTED David Hunt Julie Hunt 3007 Redwood Rd Durban, NC 27704 Subject: Request for Additional Information Application for Certificate of Coverage (COC) NCG551755 for proposed domestic discharge Under NPDES General Permit NCG550000 3007 Redwood Rd, Durham 27704 Durham Dear Mr. and Mrs. Hunt: The Division has reviewed your application for the subject permit. To enable our complete review, in accordance with N.C.G.S. 143-215.1 and 15A NCAC 2H.0105, please provide additional or revised information to address the following: 1. Complete an Engineering Alternatives Analysis (EAA): The Division requires applicants to fully document and exhaust all alternatives to surface -water discharge [G.S. § 143-215. 1 (b)(a) and (15A NCAC 211.0105 (c)(2)]. Please evaluate the feasibility of the following alternatives: connection to a municipal or regional sewer collection system, subsurface disposal (including nitrification field, infiltration gallery, etc.), single-family residence wastewater irrigation (drip and spray irrigation), reclaimed water systems, or any combination of the alternatives listed. The EAA should include boring logs and/or other information indicating that a subsurface system is neither feasible nor practical, to include written confirmation indicating that connection to a publically- owned treatment works POTW is not an option. For non -discharge alternatives, please demonstrate whether or not the physical size of the site is prohibitive, and whether or not the resulting loading rate is prohibitive based on site -specific soil conditions. For your reference the "Engineering Alternatives Analysis (EAA) Guidance Document "is enclosed. Please complete and return Attachment A. Local Governments Review Form (page 8). The EAA should also include a present -value costs analysis as outlined in the EAA guidance. Each alternative should be thoroughly evaluated, and each conclusion should be substantiated by appropriate documents and itemized budgets demonstrating that alternatives are cost prohibitive. Alternatives shall be prioritized in a table as "Summary of Discharge Alternatives," sorted by cost. ,_ DE North Carolina Department of Environmental Quality I Division of Water Resources 1617 Mail Service Center I Raleigh, North Carolina 27699-1617 919-707-9125 2. Clarify the exact location of the proposed discharge point: Provide a map with an exact point marking the location of the proposed discharge, and the point at which the discharge would connect to waters of the state. 3. Characterize Flow to Waters of the State: Please describe flow from the discharge point to the fast waters of the state. The potential flow path should include topographic features, ditches and/or conveyances that lead to waters of the state. Please have DWR's local regional office verify this information. 4. Provide a Letter from the County Health Department: New or proposed facilities must include a letter from the local or county health department evaluating the proposed site for all types of ground absorption and innovative non -discharge systems. Document the repair potential of the failed system. 5. Demonstrate Appropriate Easements: Please provide documentation to demonstrate that appropriate right-of-way or easements rights exist. Such right-of-way or easements should allow discharged wastewater to flow across property under separate ownership from the point of discharge to waters of the state. Easement agreements shall be attached to property deeds. 6. Provide Flow Estimate: Since the proposed system is a new discharge to waters of the state, please provide a 7QIO/30Q2 flow estimate at the nearest natural stream to which the discharge is going to from the following contact with the US Geological Survey: J Curtis Weaver, Hydrologist, PE USGS North Carolina Water Science Center 3916 Sunset Ridge Road Raleigh, NC 27607 Phone: (919) 571-4043 // Fax: (919) 571-4041 Email address: jcweaver(a),uses.eov If no response is received within 60 calendar days [per 15A NCAC 2H.0107(b)], the project will be deactivated and withdrawn from our review process, and DWR will recycle the documents.
