We have scheduled an on -site inspection of your laboratory for approximately 9:30 a.m., September
12, 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 1, 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 [phone] (extension 273), if you
have questions.
Sincerely, i�
