CAMBRIDGE 03633872 to-. M.M. McDaniel - Santa Ana from: T.E. Hamilton cc- J.W. Wolter W.R. Wright R.E. Schneider R.H, Locke Js<w. Farmer - South Gate DATE: October 13, 1976 subject: Air Sampling Results The results of the air sampling for tremolite fibers that I did in your plant on 9-30-76 are enclosed. They are very good and show that you have been able to maintain the low fiber levels for several months. I calculated Time Weighted Averages for the two employees and they show that you are well below the OSHA limit of 2.0 fibers/cc TWA. Employee TWA 1. B. Grant, Bagger D-18 #2, Libby #4................................. 1.08 fibers/cc 2, A. Mejia, Bagger MK, Libby #3 ........................................... 0.09 fibers/cc If you have any questions, please call. TEH:bp Enclosure Thomas E.
