Subject: Mann-Grandstaff Veterans Administration (VA) Roofing Project “Good Faith” Asbestos Investigation- Building 31

4815 North Assembly Street, Spokane, Washington Med-Tox Northwest Project No. 9139.1

Dear Ms. O’Brien, On April 24, 2025, Anthony Fullerton of Med-Tox Northwest (MTNW) visited the Mann- Grandstaff VA Medical Center located at 4815 North Assembly Street in Spokane, Washington to conduct asbestos sampling of the roof systems. This survey was completed as part of the Mann- Grandstaff VA Roofing Project under a contract with MA Architects for VA Project Number 668-24-103. MTNW was contracted to survey several buildings as part of this project (Building 1, Building 2, Building 3 and Building 31). This report focuses on the results of the sampling conducted at Building 2. The remaining buildings will be submitted in separate reports.

Building 2 is a support building. This building has two different construction dates, so the roof sections were sampled independently of one another. On the day of the survey, Devin Dalcher, the COR for the VA escorted Mr. Fullerton to each of the areas to be sampled.

The following roof sections were identified and sampled at Building 31:

• Building 31, new-white membrane roofing over insulation board on metal pan decking.

• Building 31, old- white membrane roofing over insulation board on metal pan decking.

MTNW sampled each section independent from one another. Core samples from each of the roof sections along with a sealant. MTNW collected the cores for the project and then patched the sample location and painted an orange circle around the repair for easy identification of the sample location.

Asbestos Bulk Sampling Summary

There were five (5) samples collected from four (4) homogeneous materials (HM) identified during the survey. The core samples collected from both roof sections were determined to be negative for asbestos.

Samples were collected from the white rubber membrane roofing and off-white roof top unit (RTU) curb flashing sealant. Both were determined to be negative for asbestos.

For a complete list of all samples collected, please refer to the attached Summary of Materials Sampled for Asbestos as they pertain to Building 31.

The purpose of the survey was to provide a “Good Faith Survey” (per Washington Administrative Code (WAC) 296-62-07721, (1)(c)(ii)) and to identify the materials stated above which may require removal and/or special handling before any demolition activities.

As required by 29 Code of Federal Regulations (CFR), WAC 296-62-077 and Spokane Regional Clean Air Agency (SRCAA), building inspectors certified under the Asbestos Hazard Emergency Response Act (AHERA) and employed by MTNW conducted the survey.

Med-Tox Northwest employs inspectors certified by an Environmental Protection Agency (EPA)-approved training provider to provide Asbestos Hazard Emergency Response Act (AHERA) building surveys, including renovation and demolition surveys. A copy of Mr.

Fullerton’s certificate is attached.

Table 1 provides a complete list of suspect materials determined greater than 1% asbestos as they pertain to Building 31.

Lead Containing Paint Summary

Lead was commonly used in most paint products until 1978, when it was banned from residential paints at concentrations greater than 600 parts per million (ppm); however, commercial applications with lead were still utilized and are still available. Lead is poisonous to the human body and presents a potential health hazard during any kind of disturbance (such as maintenance, including grinding, welding, and cutting) and if improperly disposed, where lead can enter drinking water supplies.

EPA defines lead-containing paint (LCP) as a concentration of 1.0 milligrams per centimeter squared (mg/cm2) or greater by X-Ray fluorescence (XRF) or 0.5 percent by weight (% wt.) or greater by total lead analysis; equivalent to 5,000 milligrams per kilogram (mg/kg). This EPA action level triggers requirements for protection of the environment, maintenance workers, and building occupants in child occupied facilities as defined by 40 CFR 745. Additionally, building components exceeding EPA lead levels may cause demolition waste streams to fail waste designation sampling performed for compliance with

WAC 173-303.

Occupational Safety and Health Administration (OSHA) and Washington Department of Occupational Safety and Health (DOSH) worker protection regulations have not defined a minimum concentration for regulating lead and has clarified that lead at any detectable concentration shall be considered regulated by 29 CFR 1926.62/WAC 296-155-176, Lead.

Paint sample results can be expressed in mg/kg (same as ppm), % wt. or mg/cm2 by area depending on the type of analytical methods used. Any positive result, regardless of the reporting method by the laboratory, will require compliance with 29 CFR 1926.62/WAC 296- 155-176.

Lead in Painted Surfaces

There were no painted components observed that will be impacted by the project.

Summary of Analysis

Asbestos-Containing Materials

A total of five (5) bulk samples were analyzed by Polarized Light Microscopy (PLM) dispersion staining EPA Method 600/R-93/116 by Seattle Asbestos Test, LLC. (SAT). SAT is accredited through the National Voluntary Laboratory Accreditation Program (NVLAP) administered by the National Institute of Standards and Technology (NIST), a division of the U.S. Department of Commerce. This accreditation does not constitute endorsement, May 12, 2025

S:\MTNW\ALLJOBS\9000-9999\9243\REPORT\Mann-Grandstaff Roof Project Letter Building 31 MTNW 9243.1 -.doc but rather a finding of laboratory competence. The NVLAP participant number for SAT is 200768-0 (certification copies and analytical results are attached.

Comments and Recommendations

Asbestos-Containing Materials

There were no asbestos containing materials identified.

We recommend that this survey report be placed on-site during renovation and/or selective demolition and copies provided to the contractor(s) bidding and performing work. DOSH, OSHA and SRCAA require that the report be on-site and available for review during the entire project duration.

1. The roof sections were sampled independently from one another. If additional materials are observed during the course of the project, they should be sampled by an AHERA inspector and analyzed by an accredited NVLAP laboratory.

This survey is not intended for use as abatement plans and/or specifications.

If you have any questions or require additional information, please call me at (253) 351- 0677.

Sincerely, Anthony Fullerton Senior Project Manager
