I will confirm your <br /> conversation with Mae. Feel free to continue emailing me with your <br /> questions, and I will coordinate a response with our staff as <br /> necessary. <br /> Jim Barton <br /> >>> "Vicki McCartney" <vmccartney@sjcehd.com> 02/10/03 03:18PM >>> <br /> Jim, <br /> 1 from Mae Hoe this afternoon concerning I had a cal g methods used for <br /> analyzing air samples, and EPA method 8015B for analyzing diesel and <br /> motor oil. I want to thank Mae Hoe for the quick response to my e-mail. <br /> It is my understanding that the following information is correct based <br /> on our telephone conversation. <br /> Mae Hoe agreed that EPA methods 8021, 8260B, and LUFT are not <br /> appropriate methods for analyzing air samples. I plan to contact the <br /> consulting firms and request that the laboratory reports be revised to <br /> indicate the appropriate methods. <br /> Mae Hoe indicated that a laboratory must run a curve for diesel and <br /> another curve for motor oil as opposed to running a single curve <br /> containing carbon 8 through carbon 40 and reporting quantities for <br /> diesel and motor oil based on the response factors generated from the <br /> carbon 8-40 curve. I plan to contact the consulting firm and request <br /> that the laboratory provide a five-point curve for diesel and a <br /> five-point curve for motor oil and report the results based on the <br /> appropriate curves. <br /> Please confirm with Mae Hoe that these conclusions are correct. <br /> Thank you, Jim. <br /> Vicki McCartney, SJCEHS <br /> 304 E.
