Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.E. Director Division of Water Quality 3GL� We have scheduled an on -site inspection of your laboratory for approximately 9:30 a:m., September 19, 2002. The scope of,the inspection will include all methods marked on Attachment I of the laboratory's current North Carolina Wastewater /Groundwater Certificate and /or marked on the application for NC Wastewater/Groundwater Laboratory Certification. A copy of the current Attachment I is enclosed for your reference. The purpose of the inspection will be to verify the laboratory's documented quality control/quality assurance procedures and adequacy in meeting the requirements of 15A NCAC 2H .0800. Enclosed are inspection checklists for the upcoming inspection. Prior to the on -site inspection, excluding the data review sections, please have your analysts complete each checklist. Any checklists that your laboratory is unable to complete, or any specific items that you do not understand, will be completed during the inspection. Completion of these checklists prior to the on -site audit, with comments by analysts relating to specific procedural differences, will help avoid any unnecessary interruption of the analyst's schedule. Please return these completed checklists, with 5 copies of completed benchsheet data for each inorganic parameter listed on your Attachment I. The checklists and requested data are to be received by this office on or before September 5, 2002. Please have available the DMR report sheets and corresponding bench data available for the months of January and March and July 2002 for us to review. If further data or report sheets are required, we will notify you during the inspection. These data sets will be used to assess the quality of your data during the inspection. Review your last inspection report to assure that all deficiencies have been corrected. If the deficiencies cited in the inspection report have not been corrected, enforcement action will be recommended. Thank you for your time and cooperation. I can be contacted at (919) 733-3908 (extension 273), if you have questions. Frederick L. Bone Laboratory Section Enclosures 1 cc: James W.

Water Pollution ADDRESS: P.O. Box 813 1060 Addor Road Pinebluff, NC 28373 CERTIFICATE NO: 134 DATE OF INSPECTION: September 20, 2002 TYPE OF INSPECTION: Maintenance EVALUATOR: Frederick L. Bone LOCAL PERSON(S) CONTACTED: Lillian Stevens I. INTRODUCTION: This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for the analysis of environmental samples. II. GENERAL COMMENTS: The laboratory is spacious and well equipped. All facilities and equipment are well maintained. Records are well kept and most data looked good. Some further quality control procedures need to be implemented. III. DEFICIENCIES, RECOMMENDATIONS, REQUIREMENTS, AND COMMENTS: General: 1. DEFICIENCY: The laboratory is not making corrections to the data in an approved manner. Cited as a comment in last years report Note: There are numerous errors in each logbook and worksheet that are not corrected in an acceptable manner. Many of the data entries are written over or scribbled out. Data entry points corrected in this manner can cause the laboratory results to be suspect. REQUIREMENT: If a mistake is made in data recording, the mistake must be removed by making a single line through the incorrect entry, recording the correct entry beside mistake, and initialing and dating the error. Ref: SW 846 Sept. 1994 Test Methods for Evaluating Wastes, Chapter One pg. 13 A. COMMENT: Some of the daily benchsheets used by the laboratory do not contain all of the necessary labeling information. No units of measure are associated with some of the data values listed on the plant bench worksheets. REQUIREMENT: The laboratory must review all benchsheets and logbooks to ensure that every entry is parked with the appropriate units of measure. Every number recorded on a benchsheet or logbook must have an appropriate unit assigned to it. y Page 2 Residual Chlorine and COD: Action taken: The laboratory requested that its method for COD analysis be changed from 5220 C to HACH 8000. In addition, the laboratory is now performing residual chlorine analysis by method 4500 G instead of method 4500 D. These corrections have been made to the laboratory certified parameter list. A copy of the updated parameter list is attached to this report. Please review this updated list to ensure that all method citations are accurate. Dissolved Oxygen: C. COMMENT: The field personnel perform and document the air calibration of the dissolved oxygen meter at the beginning of each analysis day. Samples are analyzed for dissolved oxygen in the early morning and then again in the early afternoon. The laboratory field personnel do not recalibrate the dissolved oxygen meter prior to the afternoon analysis. The field personnel do not recalibrate the meter throughout each analysis day. Calibration information is kept on a separate log from the recorded dissolved oxygen data values. RECOMMENDATION: It is strongly recommended that the meter be calibrated throughout each analysis day. This will ensure the accurate measurement of dissolved oxygen for this facility. It is further recommended that the calibration information be recorded on the same bench worksheet as the data that is being reported. This will allow for immediate verification that the meter is within proper calibration specifications. REQUIREMENT: Calibration: Follow manufacturer's calibration procedure exactly to obtain guaranteed precision and accuracy. Generally, calibrate membrane electrodes by reading against air or a sample of known DO concentration. Preferably calibrate with samples of water under test. Check one or two points frequently to confirm original calibration. If calibration changes, the new calibration should be parallel tothe original, provided that the same membrane materials are used. Ref: Standard Methods 18th Edition 4500-0 (2) and (3) p. 4-104. IV. PAPER TRAIL INVESTIGATION:. This consisted of comparing data reported on DMR's submitted' to this Division with the values obtained on laboratory bench worksheets. Data reviewed for the months of January, March, and July 2002 indicated no problems in proper data reporting. V. CONCLUSIONS: Correcting the above deficiencies and comments will help the laboratory to produce quality data and meet certification requirements. Please respond to all Deficiencies and lettered Comments cited in .this report. Report prepared by: Frederick L.
