EHSI Project 11295

1.0 EXECUTIVE SUMMARY

1.1 BACKGROUND

The National Park Service (NPS) plans to renovate Building 410 (B410) 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 B410 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 (BTEX), 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, energized air handling unit and fire door cores) 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.

The United States Environmental Protection Agency (EPA) recommends mitigation of radon gas if the average of two short-term tests taken in the lowest level of the building suitable for occupancy show radon levels that are equal to or greater than 4.0 picoCuries per liter (pCi/L).

Only one of the two radon canisters submitted for analysis registered at or above the action level and therefore no remedial actions for mitigation of radon gas are recommended at this time.

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.

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. The following samples exceeded MTCA Method A or Method B cleanup levels:

11295-B410-S1 for motor oil range, cadmium and lead 11295-B410-S2 for lead 11176-B410-S3 for cadmium 11176-B410-S4 for motor oil range and lead

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, energized air handling units, fire door cores and some roofing materials 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, whether drain sludge contained BTEX, TPH as diesel and motor oil, RCRA metals, and characterization of ionizing radiation concentrations and to provide analytical reports indicating the presence and quantity of the hazardous materials.

On September 3rd & 4th, 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

B410 is located in Vancouver, Washington at the Fort Vancouver National Historic site and part of the East Barracks portion of the site. B410 was originally constructed in 1935 with alterations and repairs made in 1987, 1990, and 2005. The building is a single-story structure on a slab-on grade foundation with a mezzanine and attic space. The building has been used as a former auto maintenance facility. Currently, it is largely unoccupied with a small area of the maintenance bay is used by a local bicycle group. The exterior of B410 is made up of wood siding, wood windows, metal doors and a composite shingle roof. Interior finishes include; bare concrete floors, vinyl composite tile (VCT), wood base, gypsum wallboard (GWB), and wood wall panels. The building is currently heated by a forced air system in the office area of the building while the auto maintenance bays are heated with natural gas ceiling mounted unit heaters. Fluorescent light fixtures provide light throughout the building.

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 F. 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 G. 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.

2.3.3 Ionizing Radiation

EHSI used a Ludlum 2241 Geiger Counter to measure for the presence of ionizing radiation levels above background on the interior and exterior of the building. Interior measurements were recorded in uniformly sized partitions of the building footprint (roughly 12’x12’ in dimensions) as well the expansion joint in the middle of the building floor foundation running east and west. Exterior measurements were generalized over roughly 10’ intervals and were taken along the ground adjacent to the building foundation. A summary of Geiger Counter readings is provided in Table 6. EHSI used Radon Testing Corporation of America (RTCA) Professional Radon Test kits, each containing one 4-inch charcoal canister in accordance with the manufacturer’s recommendations to collect a representative measure of the radon level present inside Building 410. After collection, the test kits were submitted to RTCA, a certified member of the National Radon Safety Board (NRSB) for laboratory analysis. Copies of the laboratory report and field data forms for radon are in Appendix D.

2.3.4 Petroleum Hydrocarbon Contaminated Sludge

EHSI collected four (4) sludge samples using three (3) volatile organic analysis (VOA) vials and one-two (1-2), four (4) ounce containers. 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 E.

2.4 SAMPLING RESULTS

2.4.1 Asbestos-Containing Materials

One hundred and three (103) 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 H. 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.

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

Eighty (80) 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 31.4 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.

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.

In addition to the XRF samples, EHSI collected two (2) bulk QA samples for laboratory analysis. The bulk sample results ranged from less than the reporting limit (<RL) to 0.046 percent lead by weight (%Pb/wt.). Building materials and paint containing detectable levels of lead are considered regulated by DOSH.

Table 4 summarizes bulk QA lead sample, 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.

L&I 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, select demolition) may likely 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.

In addition to XRF and bulk samples, EHSI observed two (2) lead-acid batteries inside the fire alarm control panel in Corridor 8 and three (3) lead vent pipes on the roof during the inspection.

These batteries must be disposed of in accordance with the Washington State Department of Ecology (Ecology) dangerous waste regulations or recycled at an approved 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 per liter (mg/L), 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 was analyzed for Lead (Pb) only. Copies of the analytical laboratory report and field data forms for the TCLP sample are included in Appendix C of this report.

Based on the representative waste stream that was submitted for TCLP by EHSI, this waste stream passed TCLP testing for lead (did not exceed the threshold of 5.0 ppm). If the client were to have a waste stream with similar percentages as indicated above, the waste stream would likely pass.

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.
