Adams Mayor, Town of Parkton POBox55 Parkton, NC 28371 SUBJECT: Compliance Evaluation Inspection (CEI) Town of Parkton WWTP NPDES Permit No. NC0026921 Robeson County Dear Mr. Adams: William G. Ross Jr., Secretary Alan W. Klimek, P.E., Director Coleen H. Sullins, Deputy Director Division of Water Quality Enclosed you will find a copy of the Compliance Evaluation Inspection for the inspection conducted on December 9, 2003 by Dale Lopez, Division of Water Quality -Fayetteville Regional Office (DWQ-FRO). As part of the inspection, a tour of the Wastewater Treatment Plant was conducted and the records for August 2003 were reviewed. All observations and recommendations are in Part D. Summary of Findings/Comments of this inspection report. Where recommendations are cited, we ask that you respond to the Fayetteville Regional Office by January 12, 2004 concerning how each has or will be addressed. Recommended in the last CEI report (dated June 9, 2003): 1) Please haul the sludge. It Was understood that the ORC was.planning to haul the drying bed sludge (and the stock piled sludge) to the, Robeson County Landfill during the first or second week of June 2003. (STATUS: COMPLETED) 2) Please record the process control clarifier's sludge judge readings along with the date that they were taken. (STATUS: NO SLUDGE RECORDS) 3) Please record on the DMRs all extra testing of chlorine that is performed at the 001 outfall. (STATUS: COMPLETED) Recommendations for this CEI: 1) Please clean the contact chamber; the sludge blanket was approximately one foot deep, and a small amount of bubbles from the sludge denitrification were observed. 2) Please clean the clarifier weirs. There was a moderate amount of debris partially blocking the flow across the weirs of Clarifier #1 and #2. 225 Green Street — Suite 714, Fayetteville, North Carolina 28301-5043 Phone: 910-486-1541 \ FAX: 910-486-0707 \ Internet: www.enr.state.nc.us/ENR/ An Equal Opportunity / Affirmative Action Employer - 50 % Recycled \ 10 % Post Consumer Paper One NorthCarolina Naturally Mayor Adams Page 2 December 12, 2003 If you have any questions or comments concerning this report or require clarification on part(s) of this report, please contact me at (910) 486-1541.
