Sincerely, Anna Ostendorff Technical Assistance & Compliance Specialist Division of Water Resources Attachment cc: Todd Crawford, Jason Smith, Master File #5681 On-Site Inspection Report LABORATORY NAME: Lake Toxaway Country Club NPDES PERMIT #: WQ0000731 ADDRESS: 111 Old Tom Morris Way Lake Toxaway, NC 28747 CERTIFICATE #: 5681 DATE OF INSPECTION: August 16, 2022 TYPE OF INSPECTION: Field Initial AUDITOR(S): Jason Smith LOCAL PERSON(S) CONTACTED: Gary Norton I. 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 facility is neat and well organized and has all the equipment necessary to perform the analyses. The analyst was forthcoming and responded well to suggestions from the auditor. All required Proficiency Testing (PT) Samples for the 2022 PT Calendar Year have not yet been analyzed. The laboratory is reminded that results must be received by this office directly from the vendor by September 30, 2022. The laboratory is reminded that any time changes are made to laboratory procedures, QA/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 SOP, based on the Findings, Comments and Recommendations within this report must be submitted to this office by March 1, 2023. The laboratory is also 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”. Page 2 #5618 Lake Toxaway Country Club Contracted analyses are performed by Environmental Testing Solutions, Inc. (Certification # 600). The Approved Procedure document for the analysis of the facility’s currently certified Field Parameter was provided at the time of the inspection. III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS: Documentation Comment: The Water Pollution Control System Operator's Certification number is listed on the benchsheet where the laboratory certification number (5681) is intended to be documented. A. Finding: Error corrections are not properly performed. Requirement: All documentation errors shall be corrected by drawing a single line through the error so that the original entry remains legible. Entries shall not be obliterated by erasures or markings. Wite-Out®, correction tape, or similar products designed to obliterate documentation are not to be used; instead the correction shall be written adjacent to the error. The correction shall be initialed by the responsible individual and the date of change documented. Ref: 15A NCAC 02H .0805 (g) (1). Comment: Error corrections are not consistently dated, and some overwriting was observed. B. Finding: The laboratory benchsheet is lacking required documentation: the sample collector. Requirement: All laboratories shall use printable laboratory benchsheets. Certified Data shall be traceable to the associated sample analyses and shall consist of: the sample collector. Each item shall be recorded each time samples are analyzed. Analyses shall conform to methodologies found in Subparagraph (a)(1) of this Rule. Ref: 15A NCAC 02H .0805 (g) (2) (D). Proficiency Testing C. 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 log 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, however the instructions must be maintained. Ref: Proficiency Testing Requirements, February 19, 2020, Revision 5, Section 3.6. Comment: Dating and initialing the instruction sheet for each prepared PT Sample would satisfy the documentation requirement. D. 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, February 19, 2020, Revision 5, Section 3.6. Page 3 #5618 Lake Toxaway Country Club Requirement: The laboratory shall retain all records necessary to facilitate historical reconstruction of the analysis and reporting of analytical results for PT Samples. This means the laboratory must have available and retain for five years [pursuant to 15A NCAC 02H .0805 (a) (7) (E) and (g) (1)] all of the raw data, including benchsheets, instrument printouts and calibration data, for all PT Sample analyses and the associated QC analyses conducted by all parameter methods. Ref: Proficiency Testing Requirements, February 19, 2020, Revision 5, Section 4.0. Requirement: The analysis of Proficiency Testing (PT) Samples is designed to evaluate the entire process used to routinely analyze and report Compliance Sample results. PT Samples must be analyzed the same as Compliance Samples. Also, documentation must be made on the same benchsheets used for Compliance Samples. Ref: NC WW/GW LCB Proficiency Testing Samples Analyzed and Documented Same as Compliance Samples Policy. Comment: The analyst documented the calibration on the benchsheet and only documented the results on the PT vendor paperwork. E. Finding: PT Samples are not being analyzed in the same manner as routine Compliance Samples. Requirement: Laboratories are required to analyze an appropriate PT Sample by each parameter method on the laboratory’s CPL. The same PT Sample may be analyzed by one or more methods. Laboratories shall conduct the analyses in accordance with their routine testing, calibration and reporting procedures, unless otherwise specified in the instructions supplied by the Accredited PT Sample Provider. This means that they are to be logged in and analyzed using the same staff, sample tracking systems, standard operating procedures including the same equipment, reagents, calibration techniques, analytical methods, preparatory techniques (e.g., digestions, distillations and extractions) and the same quality control acceptance criteria. PT Samples shall not be analyzed with additional quality control. They are not to be replicated beyond what is routine for Compliance Sample analysis. Although, it may be routine to spike Compliance Samples, it is neither required, nor recommended, for PT Samples. PT sample results from multiple analyses (when this is the routine procedure) must be calculated in the same manner as routine Compliance Samples. Ref: Proficiency Testing Requirements, February 19, 2020, Revision 5, Section 3.6. Comment: The laboratory is analyzing the PT Sample multiple times and averaging the results, which is not how Compliance Samples are treated. Sample duplicates are not required for Field Parameters. IV. PAPER TRAIL INVESTIGATION: The paper trail consisted of comparing original records (e.g., laboratory benchsheets, logbooks, etc.) and contract laboratory reports to Non-Discharge Monitoring Reports (NDMRs) submitted to the North Carolina Division of Water Resources. Data were reviewed for the Lake Toxaway Country Club (Water Quality permit # WQ0000731 for January, March and May 2022. The following error was noted: Date Parameter Location Value on Benchsheet Value on NDMR 05/19/2022 Chlorine, Total Residual Effluent 1.6 mg/L 1.8 mg/L Page 4 #5618 Lake Toxaway Country Club To avoid questions of legality, it is recommended that you contact the appropriate Regional Office for guidance as to whether an amended NDMR 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.
