GENERAL INFORMATION

With regard to asbestos, PBS endeavored to locate all the suspect asbestos-containing materials in the building; however, suspect asbestos-containing materials may be present and concealed within wall, ceiling, or floor spaces. If suspect materials are uncovered during demolition activities that are not identified in this report, testing should be performed prior to impact.

PBS has conducted a physical inspection of the building, compiled this report consistent with the survey scope, and certifies that the information is correct and accurate within the standards of professional quality and contractual obligations.

PBS Engineering and Environmental Inc. (PBS) has performed a general asbestos survey of accessible building areas in accordance with WAC 296-62-07721 and compiled a report with the following information:

SURVEY SCOPE

• The type, location, and approximate quantity of suspect asbestos-containing materials

• Bulk sampling of selected suspect building materials

• Inspection summary

• Laboratory analytical data of bulk material sampled

• Probable removal cost estimate

INSPECTION SUMMARY

Architectural Resource Group Pre-Renovation Asbestos Survey Report

The following materials either tested positive, or, based on the experience of PBS field personnel, were not tested and should be considered asbestos-containing. Materials that had mixed results are considered positive. Materials not sampled may contain asbestos and should be tested to verify asbestos content prior to impact through demolition, renovation, etc.

(+) Tested Positive, (M) Mixed Results, (P) Presumed Positive, (T) Previously Tested Positive.

Pre-Renovation Asbestos Survey Report

BACKGROUND

During April 2018 PBS performed a pre-renovation asbestos survey of Building 991 at the Historic Fort Vancouver site in Vancouver, Washington.

The purpose of the survey was to locate, identify, and quantify asbestos-containing building materials that may be impacted by the planned renovations of structure.

The survey is intended to comply with Southwest Clear Air Agency (SWCAA) 476 requirements, satisfy Washington Department of Labor and Industries (L&I) requirements to perform an asbestos survey per Washington Administrative Code (WAC) 296-62-07721, and hazard communication requirements for lead per WAC 296-155-176.

ASBESTOS SUMMARY

A PBS Asbestos Hazard Emergency Response Act (AHERA) accredited inspector inspected the building to determine the presence, location, and approximate quantity of asbestos-containing materials (ACM). Forty bulk samples of building materials, suspected of containing asbestos, were collected and submitted under chain of custody to Lab/Cor Portland Inc. of Portland, Oregon, for polarized light microscopy (PLM) analysis.

The following materials were identified or assumed to contain asbestos:

Multiple layers of asbestos-containing flooring materials were observed on the first and second floors of the building where the exposed surface is floor tile. In those locations, there are three layers of asbestos-containing flooring with asbestos mastic. The bottom layer is tar paper with asbestos mastic that is likely a contaminant from the flooring on top of it. These layers are approximately one inch thick. Asbestos-containing materials associated with these flooring layers are Vinyl Floor Tile/Mastic type 1, 2, and 3, and Asphalt Impregnated Paper Mastic.

Although no asbestos was detected in exposed sheet vinyl, it would be prudent to assume a layer of asbestos flooring is concealed in one of the layers below it.

Asbestos-containing pipe insulation is present and exposed throughout various locations of the basement level. It is likely the pipe insulation is also concealed inside wall cavities of the first and second floor of the building.

Asbestos-containing mill board was discovered inside the wall cavities of the former projector room.

Asbestos-containing skim coat on Firtex wall panels is present in the stage area.

Asbestos-containing plaster was discovered in various locations of the building. Laboratory results were mixed, and the plaster types are visually identical. Consequently, all plaster in the building has the possibility of containing asbestos and should be treated as such.

Please refer to the asbestos bulk sample inventory for more sample details.

Asbestos Regulations EPA, OSHA, and state and local regulations require proper removal and handling of asbestos-containing materials (ACMs) by licensed and trained asbestos abatement contractors prior to building renovations or demolition.

Removal or other impacts to ACMs should be performed by qualified and properly trained personnel in

Project No.: 25676.000 Phase No.: 0002

Fort Vancouver Historic Site Building 991

Pre-Renovation Asbestos Survey Report accordance with applicable local, state, and federal regulations. Work impacting asbestos is subject to the requirements of various regulations, including Tile 40 Code of Federal Regulation (CFR) Part 61, National Emission Standards for Hazardous Air Pollutants (NESHAPS); 40 CFR Part 763, AHERA; WAC 296-62 and 296-65; and SWCAA 476 requirements.

The EPA, Department of Ecology, and OSHA all define ACM as any material containing more than one percent asbestos. Although materials equal to or less than one percent (<1%) asbestos are not considered by regulatory agencies to be an ACM, they still have some asbestos content, and OSHA and the Department of Ecology have specific requirements for situations in which workers may encounter, disturb, or remove materials containing any level of asbestos. For the sake of hazard communication, these materials are included in the asbestos-containing materials section of this report.

This laboratory participates in the National Voluntary Laboratory Accreditation Program (NVLAP). Testing method is per 40 CFR 763 Subpart E, Appendix E, PLM. This report and the data contained therein cannot be used to claim product certification, approval, or endorsement by NVLAP, NIST, or any agency of the U.S. Government.

• "NAD" is No Asbestos Detected.

• Asbestos consists of the following minerals: chrysotile, amosite, crocidolite, tremolite, actinolite, anthophyllite.

• Material binders, such as those found in vinyl floor tiles, may prevent the detection of small diameter asbestos fibers. A gravimetric preparation and point-count is recommended for such samples.

• Quantitative analysis by PLM point count or TEM may be recommended for samples testing at < or = to 1% asbestos.

• The following estimate of error for this method by visual estimation of asbestos percent are as follows:

1% asbestos: 0-3% error, 5% asbestos: 1-9% error, 10% asbestos: 5-15% error, 20% asbestos: 10-30% error.

• This report pertains only to the samples listed on the report. Report considered valid only when signed by analyst.

This laboratory participates in the National Voluntary Laboratory Accreditation Program (NVLAP). Testing method is per 40 CFR 763 Subpart E, Appendix E, PLM. This report and the data contained therein cannot be used to claim product certification, approval, or endorsement by NVLAP, NIST, or any agency of the U.S. Government.

• "NAD" is No Asbestos Detected.

• Asbestos consists of the following minerals: chrysotile, amosite, crocidolite, tremolite, actinolite, anthophyllite.

• Material binders, such as those found in vinyl floor tiles, may prevent the detection of small diameter asbestos fibers. A gravimetric preparation and point-count is recommended for such samples.

• Quantitative analysis by PLM point count or TEM may be recommended for samples testing at < or = to 1% asbestos.

• The following estimate of error for this method by visual estimation of asbestos percent are as follows:

1% asbestos: 0-3% error, 5% asbestos: 1-9% error, 10% asbestos: 5-15% error, 20% asbestos: 10-30% error.

• This report pertains only to the samples listed on the report. Report considered valid only when signed by analyst.
