About this file
This is a Polarized Light Microscopy (PLM) Bulk Asbestos Analysis Report from Micro Analytical Services, Inc. for Cherokee Nation 35, LLC, analyzing samples from Building 1441 at Fort Bliss, Texas. The report covers 12 samples collected on 04/10/2025 and analyzed on 04/17/2025, including black fibrous roof shingles, black fibrous penetrations, and off-white non-fibrous duct mastic. Notably, none of the samples tested positive for asbestos.
The analysis was conducted using EPA-approved methods for asbestos detection, specifically EPA - 40 CFR Appendix E to Subpart E of Part 763 and EPA - 600/R-93/116. The laboratory is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) with Lab Code 200618-0 and holds a Texas Department of State Health Services (TDSHS) License No. 30-0341. The samples were examined using polarized light microscopy with dispersion staining, and the results indicate various non-asbestos constituents such as aggregate, fibrous glass, asphalt, mastic, and cellulose.

TEST METHOD: Polarized Light Microscopy with Dispersion Staining EPA - 40 CFR Appendix E to Subpart E of Part 763, Interim Method of the Determination of Asbestos in Bulk Insulation Samples EPA - 600/R-93/116: Method for the Determination of Asbestos in Bulk Building Material
STATEMENT OF LABORATORY ACCREDITATION
These samples were analyzed at Micro Analytical Services, Inc. in the Asbestos Laboratory at 11301 Richmond Ave. Suite K100B, Houston, Texas, 77082. The Laboratory holds accreditation from the National Institute of Standards and Technology under the National Voluntary Laboratory Accreditation Program (NVLAP). This laboratory is also licensed and authorized to perform as an Asbestos Laboratory in the State of Texas within the purview of Texas Civil Statutes, Article 4477-3a, as amended, so long as this license is not suspended or revoked and is renewed according to the rules adopted by the Texas Board of Health.
The samples were analyzed in general accordance with the procedures outlined in the EPA - 40 CFR Appendix E to Subpart E of Part 763, Interim Method of the Determination of Asbestos in Bulk Insulation Samples, EPA - 600/R-93/116: Method for the Determination of Asbestos in Bulk Building Material, under AHERA, for the analysis of asbestos in building materials by polarized light microscopy. The results of each bulk sample relate only to the material tested as submitted to the laboratory and the results shall not be used to claim product endorsement by NVLAP or any agency of the U.S.
Government.
Specific questions concerning bulk sample results shall be directed to the Asbestos Bulk Laboratory at Micro Analytical Services, Inc.
