His help was appreciated. The plant was compliant with both permits. Please see the attached inspection checklists for specific comments. The following observations were noted: NCO020834 The plant consists of an influent pump station with three pumps, a mechanical bar screen followed by a manual bar screen in series, vortex grit removal; dual oxidation ditches, only one of which is in use; two secondary clarifiers, four tertiary sand filters, gas chlorination followed by sulfur dioxide dechlorination; two aerobic digesters used in an alternating pattern, a lime silo and slurry mixer; cascade post aeration, and effluent flow measurement. Plans are underway to upgrade nearly all parts of this aging plant. So far, money has been obtained to replace the SCADA system and to replace the mechanical parts of both secondary clari Piers. Appropriate levels of nitrification are being achieved, as well as operational efforts to affect biological nutrient removal. The plant is part of the Tar -Pam Basin Association. Standby generator power has been expanded since the last inspection to include the disinfection system.

Sullins Director March 16, 2009 Subject: Compliance Evaluation Inspections Warren County Wastewater Treatment Plant NPDES Permit NCO020834 and Stormwater Permit NCGI 10087 Warren County Dear Mr. Freeman: Natural Resources Dee Freeman Secretary I, Dave Parnell of the Raleigh Regional Office of the Division of Water Quality, conducted two inspections on March 11, 2009, consisting of the NPDES and Stormwater inspections. The assistance of Mr. Bill Perkinson, Operator in Responsible Charge, was appreciated. Please review the attached Basinwide Information Management System (BIMS) inspection checklists summarizing the inspections. Below is a list of findings and recommendations developed from the inspections: I. NPDES Permit NCO020834 Inspection: 1. The current permit was reissued November 1, 2004 and expires October 31, 2009 2. The 2.0 MGD wastewater treatment plant consists of the following units: influent pump station, influent pumps, manual and mechanical bar screens, mechanical grit removal system, duel oxidation ditches (one in use), two secondary clarifiers, four tertiary sand filters, gas chlorination, chlorine contact tank, de -chlorination (sulfur dioxide), aerobic digester, cascade post aeration and effluent flow measurement. 3. The inspection began in the treatment plant office. All paperwork was well organized and easily accessible. Discharge Monitoring Reports were reviewed for compliance with permit limits and monitoring requirements. Chain of custody records were available and in order. The facility uses a contract laboratory. Sample storage was kept at a temperature of 4.5 degrees Celsius. The effluent composite flow proportional refrigerator temperaturewas kept at 2.0 degrees Celsius.

Overall maintenance was above average. The manual and mechanical bar screens were in acceptable condition. Grit removal was free of organic matter and excessive odor. One, of two, oxidation ditches is currently being operated. The second is not needed and is available as storage during extreme storm events Very little foam was noted. The Dissolved Oxygen level was within the acceptable range of 1.0 to 3.0 at 1.2 mg/l. The settleometer results were in the acceptable range at 650 ml/I in 30 minutes. 6. Nutrient removal is not required by the permit, since the facility is a partner in the Tar -Pam River Association. 7. The clarifiers were functioning properly and were free of weir blockages and showed no sign of short-circuiting. The sludge blanket was reported to be 2.5 feet, which is in the acceptable range of sidewall depth. 8. The aerobic digester appears to have adequate capacity with acceptable odor. 9. The disinfection (chlorine) cylinders were secured adequately, and were a safe distance from the dechlorination cylinders. All of the cylinders were under a shelter and out of direct sunlight. 10. Standby power is available and was tested during the inspection. The generator has adequate capacity to run the plant. The chlorination system is now integrated into the standby power system. 11. The effluent pump station appears to be in good operational condition. Pumps and float controls are operable. The effluent composite sample is flow proportional and collected below all treatment units. 12. The effluent pipe discharges into Fishing Creek adjacent to the plant. Access to the pipe is well maintained. The effluent appeared clear. The receiving water is free of foam and other debris. II. Stormwater Permit NCGI 10087 Inspection: A Iist of significant spills occurring in the last three years must be included as a part of the Stormwater Pollution Prevention Plan. PIease implement this requirement immediately. 2. No method of secondary containment is required at this facility. 3. Continue semi-annual qualitative monitoring and document these inspections. Warrenton WWTP CEI Page 3 4. All outfalls were inspected. Outfall #4 has been impacted by sediment from erosion occurring above the outfall. This situation must be corrected by removing the sediment from the outfall, as well; correcting the erosion on the hillside. The wastewater treatment plant is considered to be in compliance with the NPDES permit, as well as the general stormwater permit, at the time of these inspections.

Woe is me!! Actually, I don't mind. I've become more and more immersed in the SW program over time. As for Warrenton, I am pleased to know their NOI has come through the system because I communicated to them recently to submit it. I have no reason to see the NOI, so please proceed with the permit. Forward all other applications to my attention. I am always especially interested in the Concrete, Salvage Yd and Mining sectors, anyway. Myrl Ken Pickle wrote: Myrl, Are you the contact for Stormwater applications now? If not, may I ask you to please forward this request to the proper person in RRO? I have an application for a stormwater general permit, NCG11 for the Warren County WWTP in Warrenton. Surface drainage from their facility would flow into Fishing Creek, a class C NSW water in the Tar -Pamlico basin. Their NOI is in order, and I intend to issue them NCG110087, pending your oat. Do we have any problems with this site or this owner? Do you want to see the NOI? Thanks, Ken Myrl A. NiselV <. -_ < Environmental Chernist II TIC DERR - Div.
