Easley, Governor William G. Ross Jr., Secretary 'tment of Environment and Natural Resources Coleen H. Sullins, Director Division of Water Quality Below is a list of findings and recommendations developed from the inspections: co >1 O The 1.0 MGD wastewater treatment plant consists of the following units: manual and mechanical bar screens, mechanical grit removal system, influent pump station, influent pumps, aeration unit, dual clarifiers, flow distribution box, chlorine contact tank, dual feed chlorination and dechlorination, aerobic digester, sludge holding basin, sludge loading station, sludge return pump station and effluent pump station. inspections on November 25, 2008, consisting of the NPDES and Stormwater inspections. The assistance of James Pittman, Operator in Responsible Charge, was appreciated. Please review the attached Basinwide Information Management System (BIMS) inspection checklists summarizing the inspections. 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 and sample storage was kept at a temperature of 4.5 degrees Celsius. The effluent composite flow proportional refrigerator temperature was 2.5 degrees Celsius. The influent composite sampler temperature was 2.0 degrees Celsius. Enfield CEI 12.2.08 Page 2 of3 4. 5. 6. 7. 8.The aerobic digester appears to have adequate capacity with acceptable odor. 9. Stormwater Inspection:II. 1. 2.The facility is required to provide and document employee training by the permit. 3.Continue semi-annual qualitative monitoring and document these inspections. 4.All outfalls were inspected and showed no sign of illicit discharges. 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. 10. Standby power is available and was tested and operational during a recent power failure according to Mr. Pittman. The generator has adequate capacity to run the plant, partially, but in a manner to achieve desired results, according to Mr. Pittman. A list of significant spills occurring in the last three years should be included as a part of the Stormwater Pollution Prevention Plan. The disinfection (chlorine) cylinders were secured adequately, but were within 10 feet of the dechlorination cylinders. All of the cylinders were under a shelter but did receive direct late afternoon sunlight. The storage area should be expanded to further separate the cylinders and protect them from direct sunlight. 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 2.5-3 feet, which is in the acceptable range of sidewall depth. The oxidation ditches were being operated properly. Very little foam was noted. The Dissolved Oxygen level was slightly above the acceptable range of 3.0 at 3.06 mg/1. The settelometer results were in the acceptable range at 750 ml/1 in 30 minutes. 12. The effluent pipe is located adjacent to the right of way of a bridge being constructed on US 301. The pipe appears to be unaffected by the construction. The effluent discharging into Fishing Creek appeared clear. The receiving water is free of foam and other debris. 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. Although nutrient removal was not required by the permit, the facility does so in meeting its obligation to the Tar-Pam Association. Enfield CEI 12.2.Page 3 of 3 Attachment cc: Central Files SWP/RRO files Sincerely, Dave Parnell Environmental Specialist Raleigh Regional Office The wastewater treatment plant is considered to be in compliance with the NPDES permit, as well as the general stormwater pemit at the time of these inspections.

Box 699 Enfield, NC 27823-0699 SUBJECT: Advance Notice of Renewal Application Requirements Permit NC0025402 Enfield WWTP Your NPDES permit for a municipally owned/operated WWTP expires on October 31, 2009. This notice is being sent to explain the requirements for your permit renewal application. The U.S. EPA revised and expanded the application requirements for municipal permits, effective August 1, 2001. EPA form 2A is attached to this Notice, and must be used for your permit renewal application. The new application requirements mandate additional effluent testing: 1. Conduct three Priority Pollutant Analyses (PPAs) and submit results with your renewal application. Collect samples for the PPAs in conjunction with sampling for your current quarterly toxicity test. The new PPA requirements differ from previous versions. Each PPA must include: Analyses for all total recoverable metals listed in Part D of form 2A. This includes metals that are not normally monitored through your NPDES permit. Analyses for total phenolic compounds and hardness. Analyses for all of the volatile organic compounds listed in Part D. Analyses for all of the acid-extractable compounds listed in Part D. Analyses for all base-neutral compounds listed in Part D. Analyses for Total Mercury must be performed using EPA Method 1631. Conduct four toxicity tests for an organism other than Ceriodaphnia and submit results with your renewal application. The tests should be conducted quarterly, with samples collected on the same day as your current toxicity test. Call the Aquatic Toxicology Unit at (919) 733-2136 for guidance in conducting the additional tests. _ _OneNorthCarolinaNaturally NCDENR North Carolina Department of Environment and Natural Resources Division of Water Quality Sincerely, o o o o If any wastewater discharge will occur after the current permit expires, this NPDES permit must be renewed. Discharge of wastewater without a valid permit would violate Federal and North Carolina law. Unpermitted discharges of wastewater could result in assessment of civil penalties of up to $25,000 per day. The pollutant and toxicity analyses described above must accompany your permit renewal application, or any major permit modification request. The Division cannot draft your permit without the additional data. Any data submitted cannot be over 4 l/2 years old, and must account for seasonal variation (samples cannot be collected during the same season each year if collected over multiple years). PLEASE NOTE; If your existing permit contains a requirement for annual PPAs, additional PPAs are not required [provided you have conducted at least 3 scans prior to submitting your application]. Use the checklist below to complete your renewal package. The checklist identifies the items you must submit with the permit renewal application. If all wastewater discharge has ceased at this facility and you wish to rescind this permit, please contact me.
