Fort Vancouver National Historic Site – B752

EHSI Project 11035

December 24th, 2018

1.0 EXECUTIVE SUMMARY

1.1 BACKGROUND

The National Park Service (NPS) plans to renovate Building 752 (B752) at the Fort Vancouver

National Historic Site (FV NHS) located at East Vancouver Barracks, 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 B752 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 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, elevator equipment, unit heaters, and roof vents at peak of roof) 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 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).

96% 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.

One (1) hydraulic elevator reservoir was identified during the inspection as potentially impacted by the project. Sampling these oil-filled components was not within the scope of this inspection.

All oil filled components should be tested for PCBs or assumed to contain oil containing between

50 parts per million (50 ppm) and 500 ppm PCBs until tested. The oil from PCB-oil containing components (≥ 50 ppm PCBs and < 500 ppm PCBs) must be disposed as Ecology Dangerous

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. Energized electrical equipment, elevator equipment, unit heaters, and roof vents at peak of roof were not sampled but were assumed to be present based on the inspector’s experience with similar systems on other projects and are assumed to be ACMs. 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.

From September 11th to 12th, 2018, 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 752 is located at East Vancouver Barracks, Vancouver, Washington. The building is a two-story wood-framed structure with a partial attic/loft. The building sits on a brick and masonry pier foundation. The building’s roof is covered with 3-tab composite shingles. Interior floor finishes include: original tongue and groove hardwood flooring, vinyl composite tile

(VCT), and sheet vinyl flooring (SVF). Interior wall finishes include: original tongue & groove wood walls, painted plywood, painted fibrous wood walls, peg board display wall systems, and gypsum wallboard. Interior ceiling finishes include: textured wood panels, texturing on gypsum wall board (GWB), plywood, and tongue & groove wood planks. Windows throughout the building are operable and wood-framed. Heating is provided by local electric forced air furnaces, electric wall unit heaters and natural gas ceiling mounted unit heaters. There is also evidence that the building was originally heated by wood fired stoves. Hot water is provided by an electric domestic two hot water tanks. Interior lighting consists of incandescent and fluorescent ceiling fixtures and natural light from 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

C. 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). Only materials containing more than 1% total asbestos were classified as “asbestos-containing” based on USEPA, state, and local regulations.

Samples in the report labeled as ##QA are quality assurance (QA) samples. Split samples were taken from the same location and they were sent to separate laboratories. QA samples were submitted to, NVL Laboratories, Inc. (NVL) in Seattle, WA, another NVLAP laboratory.

Copies of both laboratories’ NVLAP certifications are included in Appendix D.

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 and 4, 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

Eighty-eight (88) bulk samples of suspect ACM were collected as part of the survey. Five (5) of those samples were split for quality assurance analyses. 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 and lead sample location drawings are provided in Appendix E. 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.

Preliminary analytical reports indicated that various samples contained approximately 2% chrysotile asbestos (Sample #s 11176-41). EHSI re-submitted this sample 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.

Washington State Department of Labor and Industries Division of Occupational Safety and

Health (L&I DOSH) requires special worker exposure precautions and qualifications when dealing with ACM used on seams and nail holes (refer to L&I DOSH regulations and WISHA

Regional Directives {WRD}). Any “dust creating activity”, such as: sanding, sawing, grinding, or drilling of GWB walls or ceilings shall be accomplished by certified asbestos workers using glove-bag, mini-enclosure and/or negative pressure enclosure engineering controls and work practices. As directed by WRD 23.30, for all other demolition or disturbance of GWB walls/ceilings with ACM JC, employees shall have received at least two hours of asbestos awareness training as specified L&I DOSH Instruction WAC 296-62-07722(5).

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).

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

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

Ninety-five (95) samples were analyzed for lead using the X-Ray fluorescence (XRF) analyzer.

Red bolded results indicate materials containing detectable levels of lead and “lead-based paint” (e.g., >1.0 mg/cm2) as defined by USEPA regulation 40CFR745 and

Washington State Commerce regulation WAC 365-230.

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

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 and 4, 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.

In addition to the XRF samples, EHSI collected two (2) bulk QA samples for laboratory analysis. Building materials and paint containing detectable levels of lead are considered regulated by DOSH.

Table 4 summarizes bulk QA lead samples, including sample number, material description, substrate, color, location, and analytical results. Copies of the analytical laboratory report and field data forms for lead paint are included in Appendix B of this report.

DOSH requires employers to conduct a hazard assessment and take appropriate worker protection precautions whenever disturbing materials that have detectable quantities of lead.

Since the type of work planned (e.g., sawing, grinding, demolition) may disturb the lead-containing materials, the contractor will need to conduct lead awareness training and perform an initial exposure assessment in accordance with the regulations.

EHSI also identified three (3) lead-acid batteries inside alarm and fire alarm panels on the 1st floor. If lead-acid batteries are impacted by the proposed renovation, they must be recycled by a licensed facility.

2.4.3 Toxicity Characteristic Leaching Procedure Sampling

At the request of NPS, EHSI accomplished TCLP sampling and analysis of the assumed waste stream for the project and Table 5 summarizes the analytical results. EHSI collected and composited a representative sample of the assumed waste stream for renovation activities that may impact interior building finishes, that included proportionate quantities of all materials expected to be included in the waste stream. Note: Painted metals were not included in the assumed waste stream sampling, because they are expected to be recycled and because there is no limit on metals containing paint on metals being recycled.

Ecology requires testing using the “toxicity characteristic leaching procedure” (TCLP) and segregation of construction debris if it is potentially contaminated with dangerous waste (e.g., hazardous metals-containing paint/hazardous metals-containing materials). Ecology has set a dangerous waste threshold at 5.0 milligrams (mg/L), per liter for arsenic, chromium, lead, and silver, 1.0 Mg/L for cadmium, 100 mg/L for barium and .2 mg/L for mercury.

The TCLP sample for the Project assumed waste stream was analyzed for the USEPA RCRA 8 metals: Lead (Pb), Cadmium (Cd), Chromium (Cr), Silver (Ag), Arsenic (AS), Barium (Ba), Mercury (hg), and Selenium (Se)

It should be noted that this TCLP was done on behalf of NPS for disposal cost estimating purposes. It is recommended that the contractor take their own TCLP test of their demolition waste stream including the option to not TCLP specific materials based on the ability to recycle metal and concrete painted building materials.

2.4.4 Polychlorinated Biphenyls

Ballasts

EHSI inspected every fluorescent light fixture for PCB-containing ballasts. 96% of fixtures were found to contain magnetic ballasts and must be assumed to contain PCB-containing dielectric fluid and may be disposed/recycled as Ecology Dangerous Waste. Electronic ballasts, which contain no dielectric fluid, may be disposed as construction debris. A Summary of PCB-containing ballasts and Hg-containing light tubes, CFL bulbs, and HID lamps is provided in

Table 6.

Equipment with Assumed PCB-containing oil

EHSI identified one (1) oil-containing elevator motor tank that will be removed by the planned project. The oil filled elevator motor reservoir is assumed to contain ≥50 parts per million

(PPM) and ≤500 PPM PCBs. Sampling of oil-filled components was not within the scope of this inspection. All impacted oil filled components should be tested for PCBs or assumed to contain oil containing between 50 ppm and 500 ppm PCBs until tested. The oil from PCB-oil containing components (≥ 50 ppm PCBs and < 500 ppm PCBs) must be disposed/recycled as Ecology

Dangerous Waste in accordance with USEPA regulation 40CFR 761 and Ecology Regulation

WAC 173-303 prior to recycling.

2.4.5 Mercury-Containing Fluorescent Light Tubes, CFL Bulbs, and thermostats

All fluorescent light tubes and CFL bulbs quantified in Table 6 contain Hg. Hg wastes are regulated as “universal wastes” under Ecology’s regulation WAC 173-303.
