To enable us to complete our review in accordance with N.C.G.S. 143-215.1 and 15A NCAC 02H .0105, DWR needs additional or revised information to address the following comments: 1. Plans and Specifications indicate the location of an off -site well on an adjacent property with a 50-foot buffer and an on -site well indicated with a 50-foot buffer. In accordance with 15A NCAC 02T .1006, the setback for treatment/storage units is 100-feet. Please indicate whether these wells are in use as water supplies and whether both properties are severed by a public water supply. If possible, the treatment units need to be placed at least 100-feet from any well. Please update plans and specifications accordingly for a 100-foot well setback. 2. Please submit a final electronic copy of plans and specifications to derek.denard@ncdenr.gov. 3. Engineering Alternatives Analysis (EAA). The EAA was incomplete for the following items. Please refer to the attached "Engineering Alternatives Analysis (EAA) Guidance Document" for the Present Value of Costs Analysis (PVCA). a) Assess the availability of land. If insufficient land is available onsite, assume that the necessary land can be purchased and estimate the land purchase cost based on local real estate prices. Alternatively, provide documentation to demonstrate that insufficient land is available for sale in the project area (ex. include letters from adjacent property owners indicating no interest in selling property). Please re-evaluate the following alternatives considering the cost of acquiring land: i. Land Application — Assess the land application disposal alternatives such as spray irrigation, drip irrigation, individual/ community onsite subsurface systems, and/ or innovative ground - absorption. ii. Wastewater Reuse — Wastewater Reuse Evaluate reusing all or a portion of the wastewater generated, such as for golf course irrigation, crop irrigation (e.g., hardwood or pine plantation, grasses), athletic field irrigation, landscape uses, and/ or commercial/ industrial uses. £ D_E NORTH CAROLINA Department of Environmental Quality North Carolina Department of Environmental Quality I Division of Water Resources 512 North Salisbury Street 11617 Mail Service Center I Raleigh, North Carolina 27699-1617 919.707.9000 b) Direct Discharge to Surface Waters. The EAA was missing a cost analysis for the discharge alternative. Provide the PCVA for the discharge alternative with an itemized budget. c) PVCA Summary Table. The EAA must include a Summary Cost Table, which summarizes present worth costs developed for all technologically feasible wastewater alternatives. The summary should include a breakdown of capital costs and recurring costs. Most importantly, all alternatives should be included for the comparison to the Direct Discharge to Surface Waters. Please submit the additional information requested by one of the following: Electronically: derek.denard@ncdenr.gov Address For USPS: Attention: Derek Denard Division of Water Resources WQ Permitting Section — NPDES 1617 Mail Service Center Raleigh, NC 27699-1617 Physical Address for parcel packages: Attention: Wren Tredford Division of Water Resources WQ Permitting Section — NPDES 512 N.
