Supplemental Asbestos Containing Materials Survey Report

Former USPS Space – 1st Floor

Robert N.C. Nix Federal Building

900 Market Street, Philadelphia, PA

Langan Project No.: 270054302

Dear Ms. Baxter:

Langan Engineering and Environmental Services, Inc. (Langan) has completed a supplemental asbestos containing materials (ACM) at the former US Post Office Building located at the Robert

N.C. Nix Federal Building, 900 Market Street, Philadelphia, Pennsylvania. The purpose of the survey was to confirm the presence/absence of asbestos in suspect materials under hardwood floor on the 1st floor of former USPS space.

SURVEY METHODOLOGY

The asbestos survey was conducted in accordance with the United States Environmental

Protection Agency (USEPA) protocol outlined in the USEPA publication “Asbestos in Buildings”.

Suspect ACM was categorized into various homogeneous materials, and tested for asbestos content. Sampling and analysis was conducted in accordance with EPA protocol 600/M4-82-020 per 40 CFR 763. During the survey, suspect materials observed in the building were documented, assessed, and quantified, and sampled as necessary. Samples collected were properly packaged in individual containers, sealed; catalogued and chain-of-custody documentation was completed.

OBSERVATIONS AND FINDINGS

The survey was conducted on June 5, 2019 by Langan’s Sanjay Patel, a State of Pennsylvania accredited asbestos inspector and Philadelphia asbestos investigator. Suspect materials observed during the survey were documented, assessed, quantified, and sampled as necessary. As required by the USEPA, samples were analyzed by individual layer (i.e., floor tile & the associated mastic were analyzed as two (2) separate samples). Bulk samples of the suspect ACM were analyzed using the Polarized Light Microscopy (PLM) analytical methodology in accordance with

40CFR 763 and NESHAP regulations. The samples were analyzed by AmeriSci Richmond

(AmeriSci) of Midlothian, Virginia.

Four (4) representative bulk samples of suspect felt paper and floor fill materials under hardwood flooring were collected during the survey.

A copy of laboratory test results, chain-of–custody documentation, Langan’s certifications and laboratory accreditations are provided in the Attachments.

CONCLUSIONS

Asbestos was not identified in suspect felt paper and floor fill materials under hardwood flooring and therefore, no abatement actions are necessary.

LIMITATIONS, EXCEPTIONS AND ASSUMPTIONS

Opinions and recommendations presented in this report apply to site conditions and features as they existed at the time of Langan’s site visit, and those reasonably foreseeable. They cannot necessarily apply to conditions and features of which Langan is unaware and has not had the opportunity to evaluate.

Any suspect building material that is not listed in this report must be assumed to be ACM and treated as such unless otherwise confirmed by laboratory testing.

The conclusions presented in this report are professional opinions based solely upon Langan’s visual observations of accessible areas, laboratory test data and current regulatory requirements.

These conclusions are intended exclusively for the purpose stated herein, at the site indicated, and for the project indicated.

It is important to recognize that even the most comprehensive scope of services may fail to detect all ACM that may be associated with the property. Langan cannot, therefore, act as insurers and cannot “certify” that all asbestos containing materials associated with the property have been identified, and no expressed or implied representation or warranty is included or intended in our report, except that our services were performed, within the limits prescribed by our client, with the customary thoroughness and competence of our profession.

If you have any questions or need any additional information, please let us know.

Sincerely, Langan Engineering and Environmental Services, Inc.
