Box 879 • Clayton, North Carolina 27520 • Office (919) 553-5002 • Fax (919) 553-8919 The NPW system components shall consist of a new skid-mounted packaged booster pump station, fiberglass reinforced plastic building with concrete foundation, piping modifications to the existing plant potable water system to fully segregate potable from proposed non-potable sources as described above, site work, electrical and all associated appurtenances. We understand from Susan Wilson of your office that a minor modification to our current NPDES pennit may be sufficient to cover the proposed NPW system improvements. Bruce Thompson TOWN ATTORNEY Steve Biggs TOWN MANAGER Jody L. McLeod MAYOR The Town of Clayton desires to construct an in-plant non-potable water (NPW) system for plant water use at the Little Creek Water Reclamation Facility. The project consists of segregating potable and non-potable uses such that potable water is only used at the existing control building, hand wash sinks, and emergency eyewash/shower locations. Non-potable water will be used for all other plant water needs such as influent bar screen spray wash, clarifier surface spray, chemical solution make-up, sludge thickener spray wash, process unit wash down. etc. We do not intend to utilize NPW for lawn irrigation at this time. This project will provide significant benefit to the Town of Clayton in the form of reduced operating cost and conservation of potable water resource. COUNCIL MEMBERS Robert J.

Should the Town of Clayton wish to use the non-potable water system for on-site lawn irrigation, the Town should contact this office for approval (along with the Division’s Raleigh Regional Office). The Division of Water Quality received the Town's request, dated April 27, 2004, to construct an in-plant non-potable water system using treated wastewater effluent. Authorization is hereby granted for the proposed system and any additional appurtenances associated with the system.

At 12:58 am, the CPL power supply into the Town of Clayton, this power failure and the subsequent power surges caused our emergency generation transfer switch number two to shut down on a ground fault alarm. The power was restored to the switching gear and pump station at 7:50 am, once the plant staff arrived at the scene. The final estimate of the overflow of effluent water was 273.600 gallons. The majority of the discharge percolated and evaporated in the woods behind the station. No environmental impacts were observed in the stream. In order to prevent similar problems in the future a separate power loss relay was installed on the effluent pump station. This relay will send a signal to the auto-dialer and summon on-call personnel. I am also investigating how to tie the switchgear into the facility’s alarm system. kRvn of claytoI?

Mr. Warren is in the process of developing a Stormwater Management Plan. The facility has three discharge outfalls. Gates will need to be installed to make two of the outfalls accessible, but they are all visible from the fence now. No sampling has been done yet as permit was recently issued. Jerry Rimmer performed Pretreatment Compliance Inspection (PCI) at Clayton-Little Creek WWTP facility May 24, 2004. The PCI included a site tour of the wastewater treatment facility. Mr. James Warren provided a tour of the facility. The site was operating properly at time of visit. Primary clarifier and trickling filters were not in service. The influent screens and grit chamber area was clean and no odors present. Two oxidation ditches were in operation. Two secondary clarifiers were operating with weirs level and discharge clear. A third clarifier was empty and ready for startup if needed. The filters were operating adequately. The UV disinfection system was apparently operating properly. The sludge holding tank was operating with a mixer out of service. There was a slight odor at the tank. The new sludge was being filtered in a roll-off type filter box, which was discharging into a sump and returning to the aeration basin feed. The discharge was clear. The sludge was not being hauled at the time of the visit. The sludge drying beds were not being used at this time. Clayton plans to expand both oxidation ditches to allow increased flows and provide an anaerobic and anoxic section for treatment. McGill is to get land application approval and begin hauling sludge. Clayton Manager has approved an additional operator and electrician. r July 22, 2004 Dear Mr. Biggs: 1. 2.Facility cleanliness is to be complimented.
