August 28, 1991 K.C. Potter Paducah Gaseous Diffusion Plant P.O. Box 1410 Paducah, KY 42001 Dear Mr. Potter, This letter is in response to your letter of July 15, 1991. You have asked what limit to report for asbestos analysis, the quantitation limit or the detection limit. The analytical laboratory should report what it sees within the constraints of the method used. Concentrations below the detection limit are none detected. Other values above that are reported as analyzed. There is no special requirement for results between the detection limit and any quantitation limit. The OSHA Salt Lake Technical Center reports "0.0" for results below the detection limit and the actual result for values greater than the detection limit with no comment otherwise. For your information, a copy of the OSHA method ID 160 has been included. Should you have further question, do not hesitate to call. Sincerely, Daniel T. Crane Supervisory Physical Scientist [(801) 233-4900] July 15, 1991 Mr. Daniel Crane, Supervisory Physical Scientist OSHA Salt Lake Technical Center [8660 South Sandy Parkway Sandy, UT 84070-6424] Dear Mr. Crane: Reporting Limits for Asbestos Air Concentrations Per our recent telephone conversation, I am writing to request written guidance from the Occupational Safety and Health Administration regarding reporting limits for asbestos air concentrations. There seems to be some discrepancy about which reporting limit should be used: (1) limit of detection, or (2) limit of quantitation. Guidance from your agency on this issue would be greatly appreciated. Please forward your response to K. C. Potter, Paducah Gaseous Diffusion Plant, Post Office Box 1410, Paducah, Kentucky 42001. Thank you in advance for your assistance. Sincerely, K. C. Potter, Industrial Hygienist Paducah Gaseous Diffusion Plant [Correction 2/13/04] |
