A draft permit dated May 30, 2001 has been submitted to the facility which modified the NPDES permit to increase the hydraulic design capacity from 1.8 MGD to 2.5 MGD as ;per, their request. All other permit conditions will remain the same. The fmal permit is presently under review. 2. The domestic wastewater from this facility is discharged to the City of Lumberton's wastewater treatment plant. 3. Carbon dioxide is added to the influent to neutralize pH when necessary. Carbon Dioxide adjusts a pH of 11.0 in the influent to.10.0 - 10.5. • 1 4. Three main pumps are used to pump the influent into the plant. One pump is used at any given time with the other pumps used as backups. 5. The primary clarifier appeared to be operational with no floatable foam noted on the water surface. Areas in the clarifier appeared to have paint wom from the surfaces and rusty areas were noted. These areas should be repaired in the near future to eliminate further expense to the facility. 6. The aerobic selector is made up of: influent, return activated shidge (RAS), and solids from the secondary clarifiers. The selector was installed to assist with filamentous bacteria reduction. 7. The aeration basin has a capacity of 5.5 MG. Eighteen (18) aerators are located in the basin with six (6) at the head of the basin which are 75 Horsepower and the remaining being 40 Horsepower. Ammonia and Phosphoric Acid is added to the aeration basin at a rate of 20 gallons/day to assist with treatment of the wastewater. The aeration basin appeared to be operating adequately. The most recent Mixed Liquor Suspended Solids (MLSS) result was 5900 mg/L. The MISS is analyzed daily. The optimum range for this facility is 5500-6000 mg/L as per Mr. Laney' Defamer is added to the MLSS to assist with foam reduction. 8. Clarifier #1 had a sludge depth of 10 feet with a tank depth of 15 feet. Clarifier #2 had a sludge depth of 10 feet with a tank depth of 15 feet. Clarifier #3 had a sludge depth�of 4 ''/2 feet with a tank depth of 10 feet. 9. Effluent from the clarifiers was noted on the ground beside the channel 'which flows to the effluent parshall flume. In this area the effluent is aerated before it is discharged to+tLumber River. Plexy glass had been added to different areas of the top of the channel to assist wit1i this problem but it has not eliminated it. Laney Page 4 February 25, 2002 10. The two return pumps located adjacent Clarifier # 1 and #2 were leaking oil. There is containment around this area with a dram which flows to the head of plant. The pumps should be repaired immediately to eliminate oil leakage. This was noted in the last inspection report dated March 13 2001 11. The effluent appeared to be free of solids with a brown color which is representative of this specific type of wastewater. 12. The effluent composite sampler 3710 Isco is flow proportional by constant volume/variable time. The temperature of the effluent composite sampler refrigerator was 2.7 degrees Celsius. The acceptable temperature range of samples during storage and for stored sample extracts, is 1.0 - 4.4 degrees Celsius. 13. The effluent outfall was easily accessible. The effluent discharges directly into the middle of the stream of Lumber River. 14. The effluent Badger Meter Model 2100 Ultrasonic flowmeter is used to report flow on the Discharge Monitoring Reports (DMRs). The flow meter was calibrated August 18, 2001 by facility instrumentation staff. 15. The solids wasted from the system are from the primary and secondary clarifiers. For the month of December 2001, approximately 8000 -14000 pounds per day was wasted. The biosolids are dewatered by polymer and a sludge press. The solids go into the belt press at 1 - 1 Y2 percent and leave the press at 15 - 17 percent. All biosolids are land applied to permitted land. The land application permit # WQ0002932 permits approximately 1684 acres. Approximately 800 acres are owned by the facility and the remainder is leased from other farm owners. A holding tank is located at the permitted site which can hold from 30 - 60 days of sludge. 16. The facility has a certified laboratory on site that analyzes the following NPDES permit required parameters: pH, Temperature, Dissolved Oxygen, Ammonia, BOD, Total Suspended Solids, Total Chlorine Residual and Conductivity. All other required parameters are contracted with the commercial laboratory "TBL". 17. During a tour of the certified laboratory on site, pH buffers' expiration dates were reviewed and the following findings were noted: 10.00 - expires February 2002 7.00 - expires April 2002 4.00 - expires November 2003. 18. Laboratory records were reviewed for the month April 2001 and compared to Discharge Monitoring Records (DMRs). All records reviewed appeared to be adequately reported. 19. The "Backup Operator" for this facility is Kenny Emanuel. He is a Grade III certified wastewater operator. Laney Page 5 February 25, 2002 20. The facility calculates MCRT and F/M ratios to assist with proper treatment of the wastewater as well as tracking trends with BOD and other parameters. A computer program on Microsoft Excel assist with wastewater treatment calculations. 21. Maintenance is tracked by a computer program which allows staff to email a worksheet to the maintenance staff when repairs are needed. There is not a designated maintenance staff for the WWTP. Maintenance staff is basically for the facility as a whole. PLEASE RESPOND IN WRITING TO ITEMS #9 AND #10 BY MARCH 31, 2002. Name and Signature of Inspector Belinda S.

Revised 7/16/01 by Belinda Henson BUCKEYE 1000 EAST NOIR ST., P.O. BOX 1305 LUMBERTON, NORTH CAROLINA 28359 TEL 910.737.3200 FAX 910.737.3248 Belinda Henson North Carolina Department of Environment and Natural Resources Division of Water Quality Fayetteville Regional Office 225 Green Street Suite 714 — Systel Building Fayetteville, NC 28301-5043 Subject: NPDES Compliance Inspection Report Belinda: This letter will serve as a response to the NPDES Compliance Inspection Report for the inspection of the Buckeye Lumberton Incorporated wastewater treatment plant performed February 1, 2002. Your first finding was in regards to the aerated effluent channel that flows to the Lumber River. At the time of the inspection, there were a couple of small puddles of treated effluent on the ground beside the channel. This problem began last spring when we replaced the blower that provides the air stream to some diffusers located in this channel. The diffusers are there for when we need to increase the, dissolved oxygen in the final effluent. The new blower has an increased output, and when combined with an increased flow through the channel, causes effluent to bubble over the side of the effluent trough. We had originally placed small lexan sheets over specific areas of the channel to prevent splashout, but this did not eliminate the problem. Temporarily, we intend to attach lexan sheets to the inside of the concrete wall on both sides to effectively raise the wall approximately one (1) foot. Longer term, we intend to raise the concrete formed wall of the effluent trough by approximately the same height. Additionally, we are evaluating the placement of additional diffuser stones in the trough to spread out the airflow to the channel. I have attached the work order that has been submitted to put up the sheets of Texan in the short term, and will be soliciting quotes for permanently raising this effluent trough wall. I am confident this will fix the problem. At the time of the inspection, the two return pumps (Fairbanks Morris pumps) located adjacent to the #1 secondary clarifier at the South end of the basin were also BUCKEYE LUMBERTON INC. leaking. These pumps are used to pump effluent from the aeration basin to the #3 secondary clarifier located at the North end of the basin. Again, the pumps are in secondary containment, and are functioning properly, however we do recognize this as a housekeeping issue. We have decided to put these pumps on a monthly preventive maintenance schedule so that we can tighten the packing and seals on both of these pumps at least monthly. I have attached the work order request for this task. While we are evaluating other options such as running a seal water line to this location, we have already rebuilt the #1 pump and are in the process of rebuilding the #2 pump. The maintenance depadinent replaced the bearing, seal, and sleeve on !the #1 pump as well as repacked this pump. We had to order some items for the #2 pump, so an overhaul of this pump is scheduled for when the replacement parts come in. I will follow-up with you by e-mail once this has been completed. The environmental department will also begin washing down this area weekly and noting any problems in the form of work orders that will be submitted to maintenance on a timely basis. If you have any questions, comments, or would like any additional information, please give me a call at (910) 737 — 3243. Thanks, Bryan A.
