EHSI Project 11295

1.0 EXECUTIVE SUMMARY

1.1 BACKGROUND

The National Park Service (NPS) plans to renovate Building 721 (B721) at the Fort Vancouver National Historic Site (FV NHS) located at 612 E. Reserve Street, Vancouver, Washington. The NPS has contracted EHS-International, Inc. (EHSI), a hazardous materials and industrial hygiene consulting firm, to conduct a Limited Lead and Asbestos Survey of B721 in preparation for this project. The intent of the survey is to specifically identify and quantify asbestos-containing building materials (ACM), interior lead-containing paint (LCP), other interior lead-containing building materials (LCM), to collect a lead toxicity characteristic leaching procedure (TCLP) sample representative of all materials that may be in the assumed waste stream, and to inspect and quantify fluorescent light fixtures that may contain polychlorinated biphenyl (PCB)-containing ballasts, and mercury (Hg)-containing fluorescent light tubes, compact fluorescent light (CFL) bulbs, and high intensity discharge (HID) lamps, that may be impacted by renovation activities.

1.2 EXTENT OF CURRENT SURVEY

EHSI inspected accessible interior and exterior suspect ACM that may be potentially impacted by future projects. Accessible suspect materials were sampled including, but not limited to:

interior and exterior wall systems, window systems, and mechanical systems. The LCP and LCM survey was limited to the interior of the building only. EHSI accomplished a representative destructive inspection; however, in areas inaccessible for inspection (e.g., energized electrical equipment) suspect materials were assumed to be ACM.

1.4 OPINIONS AND RECOMMENDATIONS

EHSI recommends that all impacted ACM identified in paragraph 1.3 be removed and disposed of prior to any renovation and demolition activities.

Any suspect materials not identified as having been surveyed in this report must be treated as an ACM until determined otherwise by a Certified Asbestos Building Inspector and NVLAP certified laboratory.

Washington State Department of Labor and Industries (L&I) Division of Occupational Safety and Health (DOSH) and the US Occupational Safety and Health Administration (OSHA) require employers to conduct a hazard assessment and take appropriate worker protection precautions whenever building materials are disturbed that have detectable quantities of lead. Since the type of work planned (e.g., demolition or renovation) will disturb the LCP, the contractor will need to perform an initial exposure assessment and lead awareness training in accordance with the regulations. Special care should be taken to reduce potential employee exposure to lead when demolishing porcelain bathroom fixtures and painted metal, including reducing airborne dust (eq., water misting and use of hand tools, and/or local exhaust ventilation).

A select number of fluorescent light fixtures inspected have magnetic ballasts which are assumed to contain greater than two parts per million (> 2 ppm) PCB-dielectric fluid. Magnetic ballasts must be removed from fixtures and disposed of as Washington Department of Ecology (Ecology) Dangerous Waste. All fluorescent tubes and lamps contain mercury; any fluorescent lamps/tubes to be disturbed during the project must be recycled as (Ecology) Universal Waste.

1.5 LIMITATIONS/DISCLAIMER

This report does not represent a comprehensive hazardous materials investigation for the subject property. This investigation has been conducted by EHSI under a specific scope of work authorized by the NPS for a specific purpose. Exterior lead sampling was excluded from the scope of work. All exterior painted surfaces are assumed to have lead-containing paint.

This report and accompanying appendices include the supporting information for this executive summary.

2.0 LIMITED LEAD AND ASBESTOS SURVEY REPORT

2.1 BACKGROUND

The NPS has contracted EHSI to accomplish a pre-renovation limited hazardous materials survey of the existing structure and to collect a lead-TCLP sample representative of the anticipated demolition debris. For the limited hazardous materials survey, EHSI was tasked to use applicable federal, state, and local guidelines in the accomplishment of its survey. EHSI was further tasked to provide a written survey report including: identification of all suspect materials; a determination of whether suspect materials were: ACM, LCP, and LCM, and to provide analytical reports indicating the presence and quantity of the hazardous materials.

On August 27th and 28th, 2019, EHSI conducted a Limited Hazardous Materials Survey that meets the Washington State “Good Faith Survey” requirements as cited in Revised Code of Washington (RCW) 49.26.016 and implemented by L&I DOSH regulation, Washington Administrative Code (WAC) 296-62-07721, and Regulation Section 476-040 of the Southwest Clean Air Agency (SWCAA).

2.2 BUILDING DESCRIPTION

Building 721 (B721) is located at East Vancouver Barracks, Vancouver, Washington and part of the Fort Vancouver National Historic Site. B721 was originally constructed between 1904 and 1905. The building was constructed on a stone foundation with a daylight basement and partial second floor. The wood-framed structure was originally built as a gymnasium, but later used as an event space and kitchen. The building’s envelope is made of wood siding, wood windows and doors with a composite shingle roof. The interior of the building includes hard wood flooring, vinyl composite tile (VCT), painted concrete, wood base, vinyl base, plaster and gypsum wallboard (GWB) walls and ceilings, tin ceiling panels. Heat was provided by a forced-air system in the kitchen area and was once heated by a coal fired boiler and hydronic radiators throughout. Light is provided by fluorescent light fixtures and natural light through the windows.

2.3 SAMPLING METHODOLOGY

2.3.1 Asbestos-Containing Materials

The EHSI field inspectors are asbestos Building Inspectors, certified under the requirements of the United States Environmental Protection Agency (USEPA) AHERA regulation 40 Code of Federal Regulations (CFR) 763, Subpart E. Copies of their certificates are provided in Appendix D. The number of bulk samples collected and their locations are based on the AHERA regulation and the guidelines provided by the USEPA Document 560/5-85-030a, October 1985, Asbestos in Buildings: Simplified Sampling Scheme for Friable Surfacing Materials.

EHSI collected samples and obtained analytical data for suspect ACM identified on the property. Once collected, each bulk sample was sealed in an unadulterated plastic bag to eliminate the possibility of cross-contamination. “Chain-of-Custody” tracking was followed to maintain sample integrity during handling and data reporting at EHSI and the analytical laboratory. As specified in 40 CFR Chapter 1 (1-1-87 edition) Part 763, Subpart F, and

Appendix A, each sample was analyzed using polarized light microscopy (PLM) / dispersion staining techniques, in accordance with USEPA Method 600/R-93/116. Samples were analyzed for asbestos content by Seattle Asbestos Test, LLC (SAT) located in Seattle, Washington. SAT participates in the National Institute for Standards and Technology (NIST) National Voluntary Laboratory Accreditation Plan (NVLAP). Laboratory NVLAP certifications are included in Appendix E. Only materials containing more than 1% total asbestos were classified as “asbestos-containing” based on USEPA, state, and local regulations.

2.3.2 Lead-Containing Paint/Lead-Containing Materials

EHSI used a Niton Model XLp x-ray fluorescence (XRF) Spectrum Analyzer to measure lead content on interior paint coatings and other suspect LCM. Measurements were representative of all layers of paint and/or LCM. A summary of Lead Paint XRF results is provided in Table 3.

Bulk quality assurance samples were taken for a representative number of LBP and LCM and were sent to NVL located in Seattle, Washington, an accredited laboratory for Atomic Absorption Spectroscopy (USEPA Method-7000B) by the American Industrial Hygiene Association (AIHA) under the Environmental Lead Laboratory Accreditation Program (ELLAP).

Copies of laboratory reports and field data forms for lead are in Appendix B.

All XRF sample shots are representative of that color on that specific substrate and component. The report user shall deduce from the data in Table 3, if certain building materials throughout the entire building contain lead and should not assume that what is detected is only in the specific location identified in the Table.

2.4 SAMPLING RESULTS

2.4.1 Asbestos-Containing Materials

One hundred and fifty (150) bulk samples of suspect ACM were collected as part of the survey.

Limited destructive inspection was conducted to identify hidden and/or concealed materials.

Copies of the asbestos analytical laboratory results are included in Appendix A. Asbestos sample location drawings are provided in Appendix F. Asbestos sampling information including sample number, material description, sample location, and analytical results are summarized in Table 1. The ACM and assumed ACM identified during this survey, including the quantity and location, is summarized in Table 2. All suspect materials were accessible for sampling.

X When QA lab and primary lab sample results differed, EHSI reported the most restrictive (e.g., highest % asbestos) in Table 1. Analytical results for all analyses are provided in Appendix A.

1 Point Counted Results. Preliminary analytical reports indicated that various samples contained approximately 2% to 3% chrysotile asbestos (Sample #s 74, 144, 145). EHSI re-submitted the samples reported to have greater than 1% asbestos concentration for re-analysis using the more precise EPA “Point Count” method. The “Point Count” analytical method is recommended by the EPA for samples with less than 10% asbestos. Based on the results of that re-analysis, materials found to contain less than 1% (<1%) asbestos were determined to be a non-ACM (e.g., containing < 1% asbestos fibers) and are therefore not ACM. Materials found to contain greater than 1% asbestos are identified and quantified in Table 2 of this report.

Only the “Point Count” re-analysis concentrations are listed in Table 1. Analytical results for all analyses are provided in Appendix A.

Samples containing <1% asbestos fibers are considered to be a non-ACM. Materials that contain <1% asbestos are not regulated for disposal purpose. However, removal of <1% asbestos materials are considered an unclassified asbestos operation by DOSH. As directed by WRD 23.30, for all other demolition of materials with <1% asbestos, employees shall have received at least two hours of asbestos awareness training as specified L&I DOSH Instruction WAC 296-62-07722(5). A list of materials with <1% asbestos is provided below.

<1% ACM JC on non-ACM GWB walls throughout building

Table 2 summarizes materials identified by EHSI as containing greater than 1% asbestos fibers during its survey, and un-sampled materials assumed to be ACM. The Table 2 Summary of Asbestos Containing Materials is for engineering cost estimating purposes and is not intended for bid quantifications.

ACM identified in this survey should not be disturbed unless handled by personnel who are properly trained and certified in asbestos work. Demolition and/or renovation activities by contractors may expose concealed suspect ACM. Contractors should be aware of the potential for concealed suspect ACM and have pre-planned contingencies for the handling of suspect ACM discovered during renovation and/or demolition work. Any concealed suspect ACM material that was not sampled or was assumed to be ACM and included in this report, must be treated as ACM until proven otherwise by a Certified AHERA Building Inspector and a certified laboratory. Contingency plans should include stopping work on identification of concealed suspect ACM, evacuation of the area, and sampling by a Certified AHERA Building Inspector. Concealed suspect material may include but is not limited to: spray-applied coatings, asphalt or paper vapor barriers and mastics.

2.4.2 Lead-Containing Paint and Building Materials

One-hundred seventy (170) samples were analyzed for lead using the X-Ray fluorescence (XRF) analyzer. Results marked with “<LOD” are less than the limit of detection. XRF sample results ranged from 40.4 milligrams of lead per square centimeter (mg Pb/cm2) to < LOD.

Items in Tables 3 and 4 that are bolded in red font will trigger a negative exposure assessment and lead awareness training per WAC 296-155-17609.

Table 3 summarizes XRF lead samples, including sample number, material description, substrate, color, location and analytical results.
