If you have any questions or require any farther information, please advise. /DL Enclosures To: Permit and Engineering Unit Water Quality Section Attention: Dina Sprinkle Date: March 9, 2009 NPDES STAFF REPORT AND RECOMMENDATION COUNTY: Moore Permit No. : NC0037508 PART 1— GENERAL INFORMATION 1. Facility and Address: Moore County Water Pollution Control Plant 1094 Addor Road Aberdeen, North Carolina 28315 2. Date of Investigation: February 5, 2009 3. Report Prepared by: Dale Lopez, Environmental Specialist FRO 4. Person Contacted and Telephone Number: Brant Sikes, System Superintendent (910) 281-3146 5. Directions to Site: From Fayetteville, travel on Hwy 401, turn right onto Hwy 211 North, turn left at Army Road, travel straight and cross Hwy 15/501, turn right onto Addor Road, and turn left at the entrance to the Moore County Water Pollution Control Plant. 6. Discharge Point(s), List for all discharge points: 'Latitude: 35°04'04" N Longitude: 78°28'07" W Attach a U.S.G.S. map extract and indicate the treatment facility site and the discharge point on the map. U.S.G.S. Quad No. U.S.G.S. Quad Name: G21SW Pinebluff, N.C. 7. Site size and expansion area consistent with the application? 'Yes. 8. Topography (relationship to the flood plain): 9. Location of the nearest dwelling: Not evaluated Not evaluated 10. Receiving stream or affected surface waters: a. Classification: Little River b. River Basin No. (Lumber River 03-07-50 and Sub basin No.: c. Describe receiving stream features and the pertinent downstream uses: Class C LUM50 The discharge from the Moore County Water Pollution Control wastewater treatment facility flows to Aberdeen Creek, at a point with a 7Q10 of 15.2 cfs flow (as according to the Whole Effluent Toxicity Testing Self -Monitoring Summary --- see attachment). It is classified as Class C,waters, which promotes aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. PART II - DISCRIPTION OF WASTES AND TREATMENT WORKS Volume of wastewater to be permitted: (Ultimate Design Capacity) What is the current permitted capacity of the Wastewater Treatment facility? 6.7 MGD 6.7 MGD Actual treatment capacity of the current facility (current design capacity)? 6.7 MGD Please provide a description of the existing or substantially constructed wastewater treatment facility: Raw wastewater flow enters the headworks of the plant through an influent pump station with four dry pit submersible pumps and two mechanical bar screens. The flow is pumped to the grit removal unit. The settled grit is pumped from the bottom of each chamber by two grit pumps, and into the grit washer. The grit slurry is then dewatered. A screw conveyor carries the grit to a container located outside the grit unit. The grit that is collected is sent to the landfill. Wastewater from the grit unit flows over a wier into the effluent line ensuring a grit free discharge to the two primary clarifiers (each 75 feet in diameter). Settled solids from the primary clarifiers are mechanically collected for pumping to the anaerobic digesters. In the primary clarifier, a skimmer attached to the ann collects scum from the surface and drops it into a scum box that drains outside the tank wall. Pumps located in the grit unit pump the primary sludge from the primary clarifier directly to the anaerobic digesters. The primary clarifier effluent flows to the First Stage Aeration Basins (separated into four rectangular compartments with diffused air). The mixed liquor is continuously transferred to the two Intermediate Clarifier (each 90 feet in diameter) for gravity separation and is returned to the First Stage aeration basins with the excess going to the anaerobic digesters. The wastewater from the Intermediate Clarifiers enters the Second Stage Aeration Basins, and later flows to the Final Clarifiers. The settled sludge in the Final Clarifiers is returned to the Second Stage Aeration Basins, with excess going to the anaerobic digesters. Effluent from the Final Clarifiers flows to the Chlorine Contact Basin. This is followed by dechlorination, and finally the Cascade Step Aeration. The sludge from the two anaerobic digesters is applied to thirty-six drying beds for composting by McGill Environmental. e. Possible toxic impacts to the surface waters: None 2. Residuals handling and utilizing/disposal scheme: a. If residuals are being land applied, please specify the DWQ Permit No. N/A Residual Contractor: Telephone: b. Residual stabilization: c. Landfill: N/A N/A N/A1 N/A f. Other disposal/utilization scheme (specify): The sludge from the two anaerobic digesters is applied to thirty-six drying beds for composting by McGill Environmental. 3. Treatment plant classification (attach completed rating sheet): 4. Alternative Analysis Evaluation: Has the facility evaluated all of the non -discharge options available: Please provide the regional perspective for each of the options that were evaluated. Connection to Regional Sewer System: . Land Application: Water Reuse: none evaluated none evaluated PART IV — EVALUATION AND RECOMMENDATIONS 1. The applicant is not requesting modification of the facility or increasing flow at this time. 2. A review of the compliance data did not reveal any significant violations. In -June 2006 and December 2006 this facility experienced Whole Effluent Toxicity failures. Upon investigation by this Office, the failures appeared to have been caused by the location of the dechlorination injection point too close to, and in the immediate flow path of, the 24- hour composite sample intake. That is to say, the 24-hour composite samples for the Whole Effluent Toxicity analysis contained too much. dechlorination and was not representing the true dilution of the Effluent 001 wastewater with the dechlorination agent. 3. Based upon the previous Compliance Evaluation Inspection (CEI) that was conducted on February 5, 2009, all units. were in service, and "this facility continues to maintain a very high standard for wastewater treatment". 4. This Office recommends continuation of the Special Conditions for the Whole Effluent Toxicity monitoring and the Pretreatment Program. 5. Based upon the above information, this Office recommends reissuance of the said permit for the continued operation of an existing 6.7 MGD wastewater treatment facility consisting of influent pumps, mechanical bar screen, grit removal, primary clarification, first -stage activated sludge, intermediate clarification, second -stage aeration, final clarification, anaerobic sludge digestion, sludge drying beds, and a post aeration cascade aerator, also two anaerobic sludge digesters located at the Moore County Water Pollution Control Plant on Addor Road, south of Aberdeen in Moore.

However, the following observations were noted. This facility had two center flow mechanical bar screens that were dept in the automatic mode; one was out of service. When checked at 1 PM, the 24-hour 001 effluent composite sampler had not collected sample for the morning of 2/5/2009, and the refrigerator temperature was 0 degrees Celius. The aeration in the grit removal unit was operational, however, the screw conveyer was not operational. This repair has been approved in the upgrade. The upgrade will begin in 2010, and finish in 2012. The Sludge Thickener has been out of service for approximately ten years. It will be evaluated for repair in the upgrade. On the day of the inspection, one of the four dry pit submersible pumps was clogged. The flow paced dosage for chlorine and dechlor was out -of -service because of lightning. This facility received wastewater for the following towns: Southern Pines, Aberdeen, Pinehurst, Carthage, and Pine Bluff. Two 1200 HP generators handle the whole plant. They were tested every month (sometimes weekly), and sometimes under load. The influent flow meter (used for reporting in DMRs), was calibrated quarterly.
