Dear Mr. Stallings:

Coverage (COC) to discharge under the subject state-NPDES general permit. This permit is issued pursuant
to the requirements of North Carolina General Statue 143-215 .1, the Memorandum of Agreement between
North Carolina and the US Environmental Protection agency dated October 15, 2007 (or as subsequently
amended).
Per your application for surface discharge received November 25, 2019, DWR understands that you have
recently employed an authorized engineering consultant, MacConnell and Associates, P.E. to replace your
aging septic system. We note that you received on October 3, 2019 a Notice of Violation/Intent to Enforce
from NCDENR's Raleigh Regional Office (RRO) for failure to maintain the existing system. This COC
replaces NCG550837 issued January 31, 2017 you assumed with the Change of Ownership signed
10Jan2017.
The document is specific to the Falls Lake Drainage System. Your permit package includes:
o Certificate of Coverage / Authorization to Construct / Operation & Maintenance Instructions
a A copy of General Wastewater Discharge Permit NCG570000
o A copy of the approved plans and specifications (approved 11Jan2020).
• Engineer's Certification form (to be returned to DWR upon project completion).
Your compliance under this COC requires regular treatment -system operation, maintenance and inspections
in accord with this COC and manufacturer's recommendations. You are to keep copies of all records onsite;
analyses and maintenance logs, available for DWR inspection [see Section A. (2.)]. You may comply by
securing manufacture -certified training yourself or by entering an Operations and Maintenance Contract
(OMC) with a qualified contractor.
Please note that the receiving stream is classified Water Supply (City of Raleigh), High Quality Water,
Nutrient Sensitive Waters, and wildlife Habitat Critical Area [WS-II, HQW; NSW; CA]. If your discharge
is found to contribute to any future degradation or impairment of this waterbody, an individual NPDES
permit may be mandatory. Compliance under the subject COC restricts discharge to 360 gpd [120 gal/
bedroom] in support of a three (3) bedroom single family residence (SFR). Expansion of flow to this
receiving stream will not be permitted.
