VAN DER VAART S. JAY ZIMMERMAN SUBJECT: North Carolina Wastewater/Groundwater Laboratory Certification (NC WW/GW LC) Maintenance Inspection Dear Mr. Crowder: Enclosed is a report for the inspection performed on February 3, 2016 by Anna Ostendorff, Gary Francies and Todd Crawford. Since the Finding(s) cited during the inspection were all corrected prior to the completion of the enclosed report, a response is not required. The staff is commended for taking the initiative in correcting the Findings in such a timely manner. For Certification maintenance, your laboratory must continue to carry out the requirements set forth in 15A NCAC 2H .0800. Copies of the checklists completed during the inspection may be requested from this office. Thank you for your cooperation during the inspection. If you wish to obtain an electronic copy of this report by email, or if you have questions or need additional information, please contact me at (828) 296-4677. Sincerely, Gary Francies, Technical Assistance/Compliance Specialist Division of Water Resources Attachment cc: master file Anna Ostendorff On -Site Inspection Report LABORATORY NAME: NPDES PERMIT #: ADDRESS: CERTIFICATE M DATE OF INSPECTION: TYPE OF INSPECTION: AUDITOR(S): LOCAL PERSON(S) CONTACTED: INTRODUCTION: Town of Weldon WWTP NCO025721 PO Box 551 Weldon, NC 27890 5041 February 3, 2016 Field Maintenance Anna Ostendorff, Gary Francies, and Todd Crawford Donald Crowder, Bill Hux, and Bobby Lyons This laboratory was inspected by a representative of the North Carolina Wastewater/ Groundwater Laboratory Certification (NC WW/GW LC) program to verify its compliance with the requirements of 15A NCAC 2H .0800 for the analysis of environmental samples. GENERAL COMMENTS: The facility has all the equipment necessary to perform the analyses. The system for traceability of standard and reagent preparation is effective, thorough and easy to follow. The Laboratory has done a very good job of keeping up with and implementing regulatory changes since the last inspection. Proficiency Testing (PT) samples have been analyzed for all certified parameters for the 2015 proficiency testing calendar year and the graded results were 100% acceptable. Contracted analyses are performed by Meritech, Inc. (Certification #165). Current Quality Assurance Policies for Field Laboratories and Approved Procedures for the analysis of the facility's currently certified parameters were provided at the time of the inspection. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS: Documentation Recommendation: It is recommended that the ditto marks be eliminated from the standard true value column of the Total Residual Chlorine (TRC) benchsheet. This could be replaced with a down arrow to prevent possible issues with data defensibility and/or transcription errors. Comment: The laboratory benchsheet was lacking pertinent data: Instrument identification. The NC WW/GW LC Approved Procedure for the Analysis of Total Residual Chlorine, NC WW/GW LC Approved Procedure for the Analysis of pH, and NC WW/GW LC Approved Procedure for the Analysis of Temperature documents state: The following must be documented in indelible ink whenever sample analysis is performed: Instrument Page 2 #5041 Town of Weldon Identification. Acceptable corrective action (instrument ID was added to the TRC and pH/Temperature benchsheet master copies) was performed by the laboratory and observed by the inspector to be adequate during the inspection. No further response is necessary for this Finding. pH — Standard Methods, 4500 H+ B-2000 Comment: An Automatic Temperature Compensation (ATC) check on the pH electrode is no longer required. IV. PAPER TRAIL INVESTIGATION: The paper trail consisted of comparing original records (e.g., laboratory benchsheets, logbooks, etc.) and contract lab reports to Discharge Monitoring Reports (DMRs) submitted to the North Carolina Division of Water Resources. Data were reviewed for February, June and October, 2015. The following errors were noted: Date Parameter Location Value on Benchsheet Value on DMR 2/6/15 pH Effluent 6.08 S.U. 6.8 S.U. 6/3/15 Temperature Influent 21.1 °C 22.1 °C 6/24/15 pH Effluent 6.8 S.U. 6.5 S.U. 6/26/15 Temperature Effluent 25.7°C 23.7°C 6/29/15 Temperature Influent 24.5°C 25.1 °C To avoid questions of legality, it is recommended that you contact the appropriate Regional Office for guidance as to whether an amended DMR will be required. A copy of this report will be made available to the Regional Office. V. CONCLUSIONS: All Findings noted during the inspection were adequately addressed prior to the completion of this report. The inspector would like to thank the staff for its assistance during the inspection and data review process. No response is required.
