NPDES Individual Wastewater Permit NCO021873 NPDES General Stormwater Permit NCG110000 Certificate of Coverage: NCG110142 Mayodan Wastewater Treatment Plant Rockingham County Dear Mr. Brandt: Ms. Aana Taylor -Smith of the Winston-Salem Regional Office of the North Carolina Division of Water Quality (DWQ) conducted compliance evaluation inspections at the Mayodan Wastewater Treatment Plant (WWTP) on 17 April 2013. Inspections were conducted for both the NPDES Individual Wastewater Permit and NPDES General Stormwater Permit. The assistance and cooperation of Mr. Jamie Whitten, Operator in Responsible Charge (ORC) were greatly appreciated. inspection findings are summarized below and checklists are attached for your reference. NPDES Individual Wastewater Permit NCO021873 The plant is located at the south end of Cardwell Road in Mayodan, Rockingham County, North Carolina. The NPDES individual wastewater permit authorizes the Town to operate this 2.5 MGD plant, which consists of a mechanical bar screen, dual path aeration basins, secondary clarifiers, liquid chlorination, gas/liquid dechlorination, sludge thickener, aerobic digester, and sludge drying beds. The plant is currently operating under reduced flow conditions, with an average of about 0.8 MGD. The permit authorizes the Town to discharge treated wastewater into the Mayo River, which is currently classified as Class C wasters in the Roanoke River Basin.. Site Review The facility was clean and well -secured. The treatment system was inspected and found to be operational. The tubing on the influent composite sampler was dirty and will need to be replaced.

Please correct this problem to ensure a level skimmer. Safety measures, secondary containment, and maintenance at the site were excellent. The outfall was also inspected and found to be in good condition. The discharge point appeared free of pollutant indicators. Access to the discharge point was well -maintained. Documentation Review Ms. Taylor -Smith evaluated laboratory data during the inspection. Comparison of lab reports and field monitoring data with discharge monitoring reports (DMRs) showed no concerns or errors. Chain of custody records were available and complete. The ORC visitation and operation/maintenance logs were reviewed and found to be complete and current. Records of sludge hauling and generator service were also available. The NPDES permit NC0021873 expired on 31 May 2012. The NPDES Unit of the DWQ received a renewal application from the Town of Mayodan on 19 December 2011.

Sullins, Director Division of Water Quality 31 December 2008 CERTIFIED MAIL RETURN RECEIPT REQUESTED 7008-0150-0002-7876-8782 Ms. Debra E. Cardwell, Town Manager Town of Mayodan 210 West Main Street Mayodan, NC 27027 SUBJECT: NPDES General Stormwater Permit NCG110000 Town of Mayodan Wastewater Treatment Plant, NCO021873 Rockingham County Dear Ms. Cardwell: It recently came to our attention that the Town of Mayodan does not have a general stormwater permit for its Wastewater Treatment Plant (WWTP). General stormwater permit NCG110000 is specifically for municipal WWTPs that have an industrial pretreatment program or a design flow of 1.0 MGD or greater. The Mayodan WWTP meets these criteria. This Phase I permitting program was established in 1990 for stormwater discharges from various types of industrial facilities. Attached you will find a Notice of Intent form to be used to apply for the permit. Please send the completed form along with the $100 application fee and a USGS topographic map to the Raleigh address listed on page 4 of the application on or before 16 January 2009. Please also send a courtesy copy of the form to the address listed in the footer of this letter so we are aware of your submittal. A Technical Bulletin explaining the requirements of the stormwater permit is also attached from your information. Should you have any questions, please do not hesitate to contact me at (336)771-5000.
