Batch *32172, Lab *A20775 Received September 1, 1995 P.0. * B094-1681 Bulk asbestos sample
Dear Mr. Haynes:
Sample A20775 has been analyzed by visual estimation based on EPA-600/M4-82-020 Dec. 1982 optical microscopy test method including phase contrast, polarized light, dispersion staining, and stereo microscopy.
If this sample is related to a demolition or is subject to NESHAPS 40CFR part 61 regulations, these regulations mandate that any sample containing less than 1% asbestos must be analyzed by point count. If asbestos is reported to be between It and 10%, see EPA "Clarification of asbestos NESHAP requirements to perform point counting." (Copy available.)
This report relates only to the items tested. This report must not be used to claim product endorsement by the NVLAP, the National Institute of Standards and Technology, or any agency of the U. S. Government. The results of analysis are as follows:
Lab A20775. Field L951903-1 Bulk asbestos sample This is 70% chrysotile asbestos in gray binder with rust and sand.
Very truly yours,
C-x Willard C. Dixon
