Fort Vancouver National Historic Site – B748

EHSI Project 11035

December 24th, 2018

1.0 EXECUTIVE SUMMARY

1.1 BACKGROUND

The National Park Service (NPS) plans to renovate Building 748 (B748) at the Fort Vancouver

National Historic Site (FV NHS) located at 611 Fort Vancouver Way, 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 B748 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. In addition, EHSI also collected sludge samples from interior and exterior drains to identify the presence of Benzene, Toluene, Ethylbenzene, and Xylenes, total petroleum hydrocarbons (TPH) as diesel and motor oil, and Resource

Conservation and Recovery Act (RCRA) metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver).

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. The sludge sampling was limited to drains that were accessible and representative of the interior and exterior drainage system in and around B748. EHSI accomplished a representative destructive inspection; however, in areas inaccessible for inspection (e.g., energized electrical equipment and unit heaters) 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 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 should 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).

All 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.

Ecology’s Model Toxics Control Act (MTCA) (Chapter 70.105D RCW) cleanup standards and law administer cleanup and prevention of contaminated sites. A representative number of interior and exterior drain sludge was sampled and compared to MTCA Method A and Method B cleanup levels. Based on the results, the sludge and surrounding soil should be cleaned up in accordance with MTCA standards.

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 and unit heaters 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 18th and 19th, 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 748 is located at the East Vancouver Barracks site in Vancouver, Washington. The building is a single-story wood-framed structure with a partial basement. The building sits on a concrete slab foundation. The building’s roof is covered with 3-tab composite shingles.

Interior floor finishes include: vinyl asbestos tile (VAT), carpet, and painted concrete floors.

Interior wall finishes include: original tongue and groove wood wall panels, and painted plywood, and gypsum wallboard. Interior ceiling finishes include: wood panels, exposed tongue and groove wood decking, texturing on gypsum wall board (GWB), and plywood.

Windows throughout the building are operable and wood-framed. Heating is provided by natural local electric base board heaters, and natural gas fired ceiling mounted unit heaters.

There is also evidence that the building was originally heated by a coal fired furnace system.

Hot water is provided by an electric domestic hot water tank. 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.

2.3.3 Petroleum Hydrocarbon Contaminated Sludge

EHSI collected eight (8) sludge samples using three (3) volatile organic analysis (VOA) vials and one, four (4) ounce glass jar container. The VOA vials were filled using EPA 5035 – purge and trap techniques. The four-ounce jars were filled using the same method. Following collection, the filled sample containers were placed in a cooler with ice until delivery to the analytical laboratory. EHSI field personnel checked all sample containers for completeness and cap tightness. The sample cooler was then placed in a field vehicle to await transportation to Freidman and Bruya, Inc. located in Seattle, Washington, a National Environmental

Laboratory Program (NELAP) accredited laboratory for Ecology Method NWTPH-Dx, USEPA

Method 8021B, and USEPA Method 6020B. Not all samples were submitted for each analysis.

Selected samples were submitted based upon the primary contaminants of concern. A summary of the analytical results is provided in Table 7,8, and 9 and associated laboratory report is provided in Appendix G.

2.4 SAMPLING RESULTS

2.4.1 Asbestos-Containing Materials

Ninety (90) bulk samples of suspect ACM were collected as part of the survey. Six (6) 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. Suspect materials not sampled were assumed to be ACM.

X When QA lab and primary lab sample results differed, EHSI reported the most restrictive

Appendix A.

1 Point Counted Results. Preliminary analytical reports indicated that various samples contained approximately 2% chrysotile asbestos (Sample #s 11176-315QA). 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.

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

One hundred thirteen (113) samples were analyzed for lead using the X-Ray fluorescence

(XRF) analyzer. Results marked with “<LOD” contain less lead than the limit of detection. 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.

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 three (3) 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 s perform an initial exposure in accordance with WAC 296-155-17609 and hazard communication DOSH regulations.

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 per liter (mg/L), for arsenic, chromium, lead, and silver, 1.0 mg/L for cadmium and selenium, 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), Selenium (Se). Copies of the analytical laboratory report and field data forms for the TCLP sample are included in Appendix F of this report.

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 all fluorescent light fixtures for PCB-containing ballasts. All 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.

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. Hg-containing building materials must be recycled or disposed of as hazardous waste. One (1) Hg-containing thermostat was identified in the structure.
