RE: Report for the asbestos-containing materials (ACM) investigation for the “SSA NCC Remodel Health Suite” project at the National Computer Center (NCC) located at the Social Security Administration (SSA) Headquarters Campus in Woodlawn, Maryland

Dear Ms. Raab:

Per your request, Aerosol Monitoring & Analysis, Inc. (AMA) is providing the following Hazardous Materials report for the “SSA NCC Remodel Health Suite” project at the National Computer Center (NCC) located at the Social Security Administration (SSA) Headquarters Campus in Woodlawn, Maryland. The purpose of the work was to identify and quantify ACM that may be associated with the “SSA NCC Remodel Health Suite” project.

AMA representatives Mr. Jorge Lopez and Mr. Pat Dincher, who are trained/accredited EPA asbestos inspectors, performed the ACM investigation for the “SSA NCC Remodel Health Suite”” project on April 28, 2017. AMA did not inspect the Health Suite for any other hazardous materials, such as lead or PCB’s.

ASBESTOS CONTAINING MATERIALS INVESTIGATION

The asbestos investigation work was conducted in accordance with the Asbestos Hazard Emergency Response Act (AHERA) 40 CFR Part 763 regulation. Suspect ACM associated with the “SSA NCC Remodel Health Suite”” project were visually evaluated, quantified, and locations documented. For the bulk of this investigation AMA relied on existing documentation, provided by Whitman, Requardt & Associates, LLP (WR&A), concerning ACM at the site.

During AMA’s investigation, a total of three (03) bulk samples of suspect ACM were collected and submitted for laboratory analysis. The samples were placed in sterilized “whirl-pak” bags and assigned unique identifiers, which were recorded on the bags and the bulk survey-sampling sheets.

The bulk samples of suspect ACM were submitted along with a chain of custody to AMA Analytical Services, Inc. in Lanham, Maryland. AMA Analytical Services, Inc. is accredited by the U.S. Department of Commerce, National Institute of Standards and Technology (NIST) through the National Voluntary Laboratory Accreditation Program (NVLAP) for Bulk Asbestos Analysis, (NVLAP #101143), and by the American Industrial Hygiene Association (AIHA #8863).
