INTRODUCTION: This laboratory was inspected by a representative of the North Carolina Wastewater/Groundwater Laboratory Certification Branch (NC WW/GW LCB) to verify its compliance with the requirements of 15A NCAC 02H .0800 for the analysis of compliance monitoring samples. II. GENERAL COMMENTS: The analyst was forthcoming and responded well to suggestions from the auditor. The laboratory has all the equipment necessary to perform the analyses. All required Proficiency Testing (PT) Samples have been analyzed for the 2023 PT Calendar Year and the graded results were 100% acceptable. Any time changes are made to laboratory procedures, Quality Assurance (QA) and/or Standard Operating Procedure (SOP) document(s) must be updated and relevant staff retrained. Staff must acknowledge that they have read and understand the changes as part of the documented training program. The same requirements apply when changes are made in response to Findings, Recommendations or Comments listed in this report, to ensure the methods are being performed as stated, references to methods are accurate, and the QA and/or SOP document(s) is in agreement with each approved practice, test, analysis, measurement, monitoring procedure or regulatory requirement being used in the laboratory. In some instances, the laboratory may need to create an SOP to document how new functions or policies will be implemented. Revisions to the SOPs, based on the Findings, Comments and Recommendations within this report must be submitted to this office by March 1, 2023. The laboratory is reminded that SOPs are intended to describe procedures exactly as they are to be performed. Use of the word “should” is not appropriate when describing requirements (e.g., Quality Control (QC) frequency, acceptance criteria, etc.). Evaluate all SOPs for the proper use of the word “should”. Contracted analyses are performed by Earth Environmental Services (Certification #352). Page 2 #5778 TVA Chickamauga Power Service Center III.
