In addition, there are two bulk samples of dust collected from brake drum and clutch housings. These should be analyzed for asbestos content. Upon completion of your analyses, I would appreciate your returning the unused portion of the air samples and bulk dust to me in order that I can send them to our Houston laboratory for collaborative analyses. We will send you a purchase order to cover the cost of these sample analyses. I would appreciate receiving the results by phone prior to your issuance of the written report. Attachment I summarizes the air volumes for the Millipore samples. If there are any questions, please call me (938-2000). Sincerely, Original Signed By. S. E. KiLUANY, JR. S. E.
