REGAN LINDA CULPEPPER Subject: North Carolina Wastewater/Groundwater Laboratory Certification (NC WW/GW LC) Maintenance Inspection Dear Mr. West: Enclosed is a report for the inspection performed on August 23, 2018 by Jason Smith. Where Finding(s) are cited in this report, a response is required. Within thirty days of receipt, please supply this office with a written item for item description of how these Finding(s) were corrected. Please describe the steps taken to prevent recurrence and include an implementation date for each corrective action. If the Finding(s) cited in the enclosed report are not corrected, enforcement actions may be recommended. For Certification maintenance, your laboratory must continue to carry out the requirements set forth in 15A NCAC 21-1.0800. A copy of the laboratory's Certified Parameter List at the time of the audit is attached. This list will reflect any changes made during the audit. 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.

Main St. Old Fort, NC 28762 5109 August 23, 2018 Field Municipal Maintenance Jason Smith Tony West and Aaron Vess 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 compliance monitoring samples. II. GENERAL COMMENTS: The facility is neat and well organized and has all the equipment necessary to perform the analyses. Benchsheets are well designed, easy to follow and concise. Records are well organized and easy to retrieve. All required Proficiency Testing (PT) Samples have been analyzed for the 2018 PT Calendar Year and the graded results were 100% acceptable. Contracted analyses are performed by Water Tech Labs, Inc. (Certification #50) and Environmental Testing Solutions, Inc. (Certification #600). Quality Assurance Policies for Field Laboratories and Approved Procedure documents for the analysis of the facility's currently certified Field Parameters were provided at the time of the inspection. Requirements that reference 15A NCAC 2H .0805 (g) (1), stating "Data pertinent to each analysis must be maintained for five years. Certified Data must consist of date collected, time collected, sample site, sample collector, and sample analysis time. The field benchsheets must provide a space for the signature or initials of the analyst and proper units of measure for all analyses", are intended to be a requirement to document all pertinent information for historical reconstruction of Page 2 #5109 Town of Old Fort WWTP data. It is not intended to imply that existing records are not adequately maintained unless the Finding speaks directly to that. III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS_ Documentation A. Finding: The laboratory needs to document traceability information of purchased materials and reagents. Requirement: All chemicals, reagents, standards and consumables used by the laboratory must have the following information documented: Date Received, Date Opened (in use) Vendor, Lot Number, and Expiration Date. A system (e.g., traceable identifiers) must be in place that links standard/reagent preparation information to analytical batches in which the solutions are used. Consumable materials such as pH buffers and lots of pre - made standards are included in this requirement. Ref: Quality Assurance Policies for Field Laboratories. Requirement: Data pertinent to each analysis must be maintained for five years. Ref: 15A NCAC 2H .0805 (g) (1). Proficiency Testing B. Finding: The laboratory is not documenting the preparation of PT Samples. Requirement: PT Samples received as ampules are diluted according to the Accredited PT Sample Provider's instructions. It is important to remember to document the preparation of PT Samples in a traceable loq or other_ traceable format. The diluted PT Sample then becomes a routine Compliance Sample and is added to a routine sample batch for analysis. No documentation is needed for whole volume PT Samples which require no preparation (e.g., pH), but it is recommended that the instructions be maintained. Ref: Proficiency Testing Requirements, May 31, 2017, Revision 2.0. Comment: This Finding only applies to Total Residual Chlorine for the laboratory's currently certified parameters. Dating and initialing the instruction sheet for each prepared PT Sample would satisfy the documentation requirement. C. Finding: The laboratory is not documenting PT Sample analyses in the same manner as routine Compliance Samples. Requirement: All PT Sample analyses must be recorded in the daily analysis records as for any Compliance Sample. This serves as the permanent laboratory record. Ref: Proficiency Testing Requirements, May 31, 2017, Revision 2.0. Comment: The analysis of PT Samples is designed to evaluate the entire process used to routinely report Compliance Sample results; therefore, PT Samples must be analyzed and the process documented in the same manner as Compliance Samples. Comment: The laboratory was only documenting the results on the form submitted to the vendor. Page 3 #5109 Town of Old Fort WWTP M D. Finding: The laboratory is not analyzing PT Samples in the same manner as routine Compliance Samples. Requirement: All PT Samples are to be analyzed and the results reported in a manner consistent with the routine analysis and reporting requirements of Compliance Samples. Laboratories must document any exceptions. All PT Sample analyses must be recorded in the daily analysis records as for any Compliance Sample. This serves as the permanent laboratory record. Ref: Proficiency Testing Requirements, May 31, 2017, Revision 2.0. Comment: The laboratory's common practice was to analyze a known standard along with the PT Sample as additional QC. Since this is not performed with all Compliance Samples, it is considered additional QC. However, additional QC is recommended as part of the troubleshooting and corrective action process, prior to analyzing remedial PT Samples. Comment: The laboratory was also analyzing PT Samples multiple times and reporting an average of all results. Compliance samples are not analyzed and reported in this manner. 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 the Town of Old Fort WWTP (NPDES permit # NC0031879) for January, March and June 2018. The following error was noted: Date Parameter Location Value on Value on eDMR Benchsheet 6/26/2018 pH Effluent 7.2 S.U. 7.4 S.U. To avoid questions of legality, it is recommended that you contact the appropriate Regional Office for guidance as to whether an amended DMR(s) will be required. A copy of this report will be made available to the Regional Office. V. CONCLUSIONS: Correcting the above -cited Findings will help this laboratory to produce quality data and meet Certification requirements. The inspector would like to thank the staff for their assistance during the inspection and data review process. Please respond to all Findings and include supporting documentation, implementation dates and steps taken to prevent recurrence for each corrective action.
