1.0 SUMMARY

From March 23 - 26 2017, GenCorp Services sampled and assessed the compartments listed below on the CGC Sledge. Asbestos Containing Material Bulk Sampling, Asbestos Air Sampling, Lead Paint Bulk Sampling and Lead Dust Wipe Sampling were conducted in these compartments.

SanAir Technologies Laboratory analyzed the samples. The results, summary of the findings, and our recommendations are in the following sections. Not all areas were visible at the time of sampling and the quantities listed may not be an accurate representation.

Note: All samples were below OSHA approved exposure limits and therefore no further action is required.

Recommendations Throughout Area:

• If materials are found and suspected to contain asbestos, they should be tested before disturbed.

• The air sampling results are below the OSHA approved exposure limit of 0.01 fibers/cc and therefore no further action is required.

• The overhead and bulkheads appear to be deteriorated but many areas have been encapsulated. Area should be abated or stabilized if found to contain asbestos.

• The deck appears to be intact.

The final report cannot be reproduced, except in full, without written authorization from SanAir.

Fibers smaller than 5 microns cannot be seen with this method due to scope limitations. The accuracy of the results is dependent upon the client’s sampling procedure and information provided to the laboratory by the client. SanAir assumes no responsibility for the sampling procedure and will provide evaluation reports based solely on the sample and information provided by the client. This report may not be used by the client to claim product endorsement by NVLAP or any other agency of the U.S. government.

For NY state samples, method EPA 600/M4-82-020 is performed.

Polarized- light microscopy is not consistently reliable in detecting asbestos in floor covering and similar non-friable organically bound materials. Quantitative transmission electron microscopy is currently the only method that can be used to determine if this material can be considered or treated as non-asbestos containing.
