Project: Building 1300 Pre-renovation Survey

MR. SHOEMAKER:

Atlas Technical Consultants, LLC (Atlas) has conducted a client-directed asbestos survey, including approximately 5,200 square feet of office space on the west portion of Building 1300 located at Mountain Home AFB. The survey was conducted on October 23, 2023 prior to renovation.

At the time of the survey, the building was occupied and furnished. Portions of the structure may not have been accessible, specifically wiring. Our survey identified the following Asbestos Containing Materials (ACM):

*Atlas sample ID numbers referenced above represent the homogenous materials in an area followed by a sequential sample number. For example, sample 2-3 represents homogenous area two (2) with a sequential sample number of three (3). During this inspection, Atlas observed 16 homogenous materials with a total of 48 samples collected.

1 Category, as defined by NESHAP, below.

2 Friability of building material as it exists in the building, as installed, and as observed during the inspection. Condition may change depending upon demolition or renovation techniques.

3 Quantities are estimations only and must be verified by the Abatement Contactor.

4 Asbestos containing 9” x 9” vinyl floor tile was found beneath carpet through the planned renovation space. Atlas was unable to verify the amount of vinyl floor tile present without removing carpet throughout the area. Approximately 4,400 square feet of carpet was observed throughout the renovation space that may conceal asbestos containing vinyl floor tile.

The United States Environmental Protection Agency’s National Emission Standard for Hazardous Air Pollutants (NESHAP), Asbestos Final Rule currently classifies asbestos under three separate categories; they are as follows:

Category I Non-friable ACM: This category includes all asphalt roofing products and resilient flooring products (floor tile and sheet flooring). In theory, these materials consist mostly of cohesive elements which rarely release significant numbers of asbestos fibers into the air, even when they are damaged. In practice, however, roofing and flooring can become brittle or crumbly with age and be damaged enough by construction equipment to release fibers into the air during removal. At this point, the EPA requires special methods during removal and handling of the materials to protect people against fiber release. If, on a specific renovation or demolition project, there is a chance of

2791 S. Victory View Way Boise, ID 83709

208.376.4748 | oneatlas.com fiber release associated with roofing or flooring, we assume that special methods (abatement by removal) will be required. In the case of intentional burning, all ACM, friable or non-friable, must be removed prior to any such activities.

Category II Non-friable ACM: This category includes all other non-friable asbestos containing materials. These materials must always be removed using special abatement methods if they are expected to be disturbed or damaged in any way during renovation or removal activities.

Regulated Asbestos Containing Materials (RACM): All friable asbestos containing materials, including Category I and II materials that have become or will become friable due to renovation or demolition activities. Friable asbestos is defined as any material containing more than one percent asbestos that, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure.

These materials must always be removed using special abatement methods prior to any renovation or demolition activity.

Atlas was able to perform some limited destructive sampling, which included exposing walls, ceilings, removing floor coverings, etc. However, Atlas cannot guarantee that hidden ACM is not still present in the building without complete deconstruction of the structure. Additional sampling may be necessary if demolition or renovation activities expose previously unidentified suspect materials. During demolition or renovation activities, a National Emission Standard for Hazardous Air Pollutants (NESHAP) Competent Person must be on site in the event additional ACM is discovered and/or disturbed as outlined in Environmental Protection Agency (EPA) regulations 40 CFR Part 61.

A representative sample of the building materials will need to be collected prior to demolition or renovation activities in order to perform lead waste characterization for disposal. Additionally, the contractor will need to follow OSHA’s Lead in Construction Rule and either provide historical data no older than one (1) year that shows similar techniques, equipment, and the same personnel completing the present tasks, or an initial exposure assessment will need to be performed during demolition or disturbance of painted components.

Atlas is pleased to have this opportunity to serve you and looks forward to a continuing relationship as your environmental consultant. If you have any questions regarding this letter or the attached analytical results, please feel free to contact Atlas at (208) 376-4748.

Sampled by: Caleb Gans

Analyzed by: Thomas Johnson Microscopist

Sample components are identified using polarized light microscopy (PLM) coupled with dispersion staining methods as determined by visual estimation.

Small asbestos fibers may not be detected by PLM due to the resolution limitations of the optical microscope. Detecting asbestos in non-friable organically bound materials is not consistently reliable using PLM analysis. The non-detection of asbestos fibers in floor tile by PLM is of itself inconclusive. Confirmation by Transmission Electron Microscope (TEM) is recommended for negative floor tile samples. This test report relates only to the items tested in the sample as submitted to the laboratory.
