1.0 INTRODUCTION

Mabbett and Associates, Inc. (Mabbett®) performed a limited survey for Regulated Building Materials (RBM) as part of the project to Replace Roofs of Buildings 1, 20, 22, 23, 33, and 100 at the Seattle Campus of the VA Puget Sound Health Care System located in Seattle, Washington, VA Project No. 663-18-102. The site survey was performed on June 5 and June 6, 2019 and July 9 and July 10, 2019 by United States Environmental Protection Agency (US EPA) trained asbestos inspector, Mr. Michael F. Delaney, and consisted of the following activities:

A review of previous facility regulated building materials reports;

An Asbestos Containing Material (ACM) survey of suspect roofing materials (Analysis by polarized light microscopy [PLM] and Transmission Electron Microscopy [TEM]); and Limited Lead Containing Paint (LCP) sampling (Analysis by atomic absorption [AA]).

This survey was limited to areas of the roofs of Buildings 1, 20, 22, 23, 33, and 100 that were outlined in the Statement of Work dated August 1, 2018.

2.0 ASBESTOS SURVEY

2.1 Sampling Methodology

Site inspection work was performed on June 5 and June 6, 2019 and July 9 and July 10, 2019 by US EPA accredited asbestos inspectors, Mr. Michael F. Delaney. In accordance with the scope of work, suspect ACM was sampled and collected in general conformance with 40 CFR Part 61 “National Emissions Standards for Hazardous Air Pollutants (NESHAP)”, 40 CFR Part 763 “Asbestos Hazard Emergency Response Act (AHERA)”, and applicable Washington regulations.

The collected bulk samples were submitted under standard chain of custody procedures to ProScience Analytical Services, Inc. (ProScience) of Woburn, MA. ProScience is accredited by the American Industrial Hygiene Association (AIHA) and participates in the National Voluntary Laboratory Accreditation Program (NVLAP). Sample analysis was conducted by PLM, in accordance with EPA Method 600/R-93/116, using stop positive methodology. Confirmatory analysis of some samples by TEM was conducted as required.

All bulk sample results from this inspection are summarized in Appendix A, Summary of Asbestos Sampling Results.

The Environmental Protection Agency (EPA), Occupational Safety and Health Administration (OSHA), and The Puget Sound Clean Air Agency defines ACM as any material that contains greater than one percent (>1%) asbestos. As such, the analytical laboratory identified bulk samples of suspected ACM as positive for asbestos when they met or exceeded the regulatory criteria of greater than one percent (>1%) asbestos. Laboratory reports and the chain of custodies are provided in Appendix B of this report.

2.2 Summary of Asbestos Containing Materials (ACM) Findings

Mabbett identified forty-nine (49) types of homogenous materials and collected one hundred thirty-five (135) representative bulk samples. The laboratory analytical data indicated that twelve (12) of the homogenous areas were identified or assumed to be ACM. All samples were analyzed by PLM. Four (4) samples were re-analyzed by TEM, as recommended by the laboratory. Estimated quantities of materials identified as ACM are presented in Table 1 below:

3.0 LEAD CONTAINING PAINT SURVEY

The limited LCP survey and sampling was conducted on July 9 and July 10, 2019. The limited LCP survey included the collection of paint chips from building surfaces that may be impacted by the proposed work. Paint chip samples were submitted under standard chain of custody procedures to ProScience of Woburn, MA. Analysis was conducted using AA EPA method SW846-7420/3051.

The results of the limited LCP sampling are summarized in Table 2, with laboratory reports provided in Appendix C.

4.0 CONCLUSIONS AND RECOMMENDATIONS

4.1 Asbestos

Identified ACM must be abated and properly disposed of prior to disturbance by state licensed and properly trained contractors. All abatement must be performed in accordance with Federal, State and local requirements. Any suspect materials encountered during demolition or renovation activities that were not identified in this report as being non-ACM, should be assumed to be ACM unless sample results prove otherwise. Suspect ACM that may be present within the walls, above inaccessible hard ceilings, or in other inaccessible locations, should be assumed to contain asbestos if discovered during any demolition or renovation process or until otherwise verified.

4.2 Lead Containing Paint

The purpose of the limited LCP survey was to identify similar areas of LCP. During the on-site survey, representative samples of similar coatings were collected and analyzed for lead content. The regulations addressing LCP in non-residential buildings are focused on occupational exposures involved with paint-disturbing activities and related waste-disposal activities.

Occupational exposure to lead in construction is regulated by OSHA regulation 29 CFR 1926.62 “Lead in Construction”, as well as other applicable state and local regulations. These regulations involve the air monitoring of

Page 4 July 31, 2019 Project No. R2019016.000.001 S:\ADMINA\2019016 Seattle VAMC\000\001\Seattle VAMC Roof Survey Report - Final.doc workers to determine exposure levels when disturbing paint containing measurable concentrations of lead. A LCP survey cannot determine the safe level of lead for the purpose of paint-disturbing activities, but is intended to provide guidance as to the locations of LCP. Employers and contractors may use this information to better determine where worker exposures to airborne lead may occur and, through the interpretation of LCP concentration data, assess the potential magnitude of exposure to their employees and identify the controls necessary to limit health risks.

A concentration of lead greater than or equal to 0.5 mg/Kg percent by weight or 1.0 mg/cm2 exceeds EPA and HUD residential standards is considered an indicator of risk. Representative samples of LCP waste to be generated during building renovation, or following demolition but prior to disposal, should be collected and analyzed using toxicity characteristic leaching procedure (TCLP) in accordance with 40 CFR Part 261. Management and disposal of lead containing waste must be done in accordance with all applicable local, state, and federal regulations.

OSHA regulations may require certain procedures for any paint that contains lead, even if it is below these levels. All LCP identified, regardless of the lead content, should either be sampled and analyzed by TCLP and then handled/disposed of accordingly, or segregated from other large-scale debris and then managed as hazardous waste in accordance with federal, state and local hazardous waste disposal regulations.

5.0 LIMITATIONS

This survey report is the result of a diligent and thorough inspection for regulated building materials of the areas and materials that may be impacted by the proposed roof replacement of Buildings 1, 20, 22, 23, 33 and 100. Inaccessible areas and interior materials were not included in this survey. Although a comprehensive inspection was performed, Mabbett does not claim to have identified all hazardous materials that could be present (for example, materials potentially located within the inaccessible areas). Mabbett has conducted this assessment with reasonable care and has performed this project in accordance with generally accepted industry standards. There can be no assurances, and Mabbett makes no assurances, that the information, research, and technology used to prepare this report may not change in the future, thus affecting the results reported herein.
