Georgiaffecific ^ intracompany memo to Mr. M. A. Palnowskl from G. W. Green subject Airborne Asbestos Monitoring at Chicago Joint Ceasnt Plant location location date Chicago Tigard April 29 Three production worker* *t the Chicago Plant were Benito ad for airborne asbestos fibara on April Jr, 1976. All the tin* weighted iverages continn* to be wall below the of 5 fibers per nilllliter. The overall average of 0.57 is slightly higher than the previous entn . The reason for this is explained in the letter fron George Fowler which Is attached to this report. The fiber counts were dene by Dawn Steyaert. GUG/gvp Att. * cc: Mr. J. R. Bnrd - Portland ^ Mr. T.

W. Green from G. F. Fowler subject Chicago Sampling for Airborne Asbestos ^ location location date Tigard Marietta April 6, 1976 On 4/5/76 samples were taken at the Chicago Plant. Production was limited to Ready Mix and Ready Mix Filler. Mike Oravis was a new man doing the dry blending It was noted that due to his inexperience, an excess amount of dust was created. Generally, good housekeeping was observed at most working stations. Production for the day was just slightly down from their average production. Please note that on two of the reports, additional pumps were used. This was due to minor malfunctions. Sample #364 is being returned as a blank. GFF/gp^ $; G. F. F.
