ROY COOPER Governor MICHAEL S. REGAN Secretary LINDA CULPEPPER Director NORTH CAROLINA Environmental Quality January 6, 2020 MEMORANDUM To: Jeff Poupart�� Through: John Henness9�l',%_ From: Derek Denard �G Subject: SOC for Review & Approval to Be Sent to Public Notice EMC SOC WQ S19-003 Stanly County / West Stanly WWTP Permit No. NCO043532 Stanly County Please find the attached copy of the SOC for the Stanley County. Timeframe: SOC Effective: January 1, 2020. SOC Expiration: January 31, 2023. Stipulations: County Stanley has requested SOC WQ S19-003 for its West Stanly WWTP, a 0.9 MGD WWTP that discharges treated wastewater to the Rocky River (Outfall 002) and Long Creek (Outfall 001), both Class C in the Yadkin -Pee Dee River Basin. The County is unable to consistently comply with effluent limits for Total Suspended Solids (TSS), Fecal Coliform, BOD, and Ammonia as Nitrogen. Compliance will require preparation and implementation of plans and specifications for construction of additional treatment works and upgrades. Summary of Necessity Narrative: The WWTP serves the Town of Stanfield, Town of Oakboro, City of Locust, Red Bridge Golf Community, the Red Cross Community, and the Ridgecrest Community. The County has no control over the flow from these systems. The permitted capacity is 0.9 MGD with an expansion up to 1.2 MGD. Violations for BOD, TSS, Ammonia, and Fecal Coliform have occurred (see attached) during time periods of high flow. The contributing factor to flow issues is inflow and infiltration (I & 1). There is a design limitation at peak flow that the engineers' report discusses. A peaking factor of 3.6 was determined for the WWTP. Fundins: The County has been awarded a loan from the Clean Water Revolving Fund (CWSRF) in the amount of $3,364,130. ql�� North Carolina Department of Environmental Quality I Division of Water Resources z:.e00_f N 512 North Salisbury Street 11617 Mail Service Center I Raleigh, North Carolina 27699-1617 NORTH CAROI.MA ma.oa. 919.707.9000 MEMO EMC SOC WQ S 19-003 January 6, 2020 Page 2 of 4 Outstanding City Penalties: The county has requested remissions for the following: 04-2019 LV-2019-0262 for BOD & TSS $2,608.75 (costs $108.75) 03-2019 LV-2019-0261 for BOD, TSS & Fecal Coliform $4,358.75 (costs $108.75) 02-2019 LV-2019-0259 for BOD, TSS & Fecal Coliform $3,358.75 (costs $108.75) Total $10,326.25 (costs $326.25) Civil Penalties to be held in absence as stated in the SOC: The County has outstanding civil penalty assessments that total $10,326.25.

BOD and Ammonia were not given interim limits because the Rocky River and Long Creek do not have assimilative capacity. Additional Flow Allocation: An initial allocation of 80,000 gallons of additional wastewater will be allowed on the effective date of this Special Order by Consent. An additional flow allocation of 30,000 gallons of wastewater may be made following the successful completion and placement in service of the new secondary clarifier.
