Pre-Renovation Hazardous Building Materials Survey Report

BACKGROUND

On February 27, 2024, PBS Engineering and Environmental Inc. (PBS) performed a pre-renovation hazardous building materials survey at the Oregon Military Department Owen Summer Building located at 1776 Militia Way

SE in Salem, Oregon. The purpose of the survey was to locate, identify, and quantify asbestos -containing building materials, lead-based paint, and other regulated hazardous building materials that may be impacted by planned facility improvements.

The survey is intended to satisfy the Oregon Department of Environmental Quality (DEQ) requirements to perform an asbestos inspection prior to renovation or demolition activities under Oregon Administrative Rule (OAR)

340-248-0270 and Occupational Safety and Health Administration (OSHA) hazard communication.

This survey report is not suitable nor is it intended to be used as an asbestos abatement project design or an abatement bid document.

BACKGROUND

1. 4

1776 Militia Way SE

Oregon Military Department

Oregon Military Department

Pre-Renovation Hazardous Building Materials Survey Report

The building was inspected by a PBS Asbestos Hazard Emergency Response Act (AHERA) accredited inspector to determine the presence, location, and approximate quantity of asbestos-containing materials (ACMs).

Sixty-three bulk samples of building materials, suspected of containing asbestos, were collected and submitted under chain of custody to Eurofins LabCor of Portland, Oregon, for polarized light microscopy (PLM) analysis. The following materials were found to contain asbestos.

⦁ The black sealant on the exterior windows contains asbestos. The material is a black putty -type material applied between the glass and aluminum frames of the exterior windows and storefront assemblies. The material was observed both on the interior and exterior of the windows. The material is playable, non -friable, and was observed in good condition. The rubber molded seals are not asbesots -containing.

⦁ The roofing is composed of a newer, TPO-type single-ply membrane roof on flat areas and metal roofing at pitched areas. White asbestos-containing sealant was identified on the metal roofing. The asbestos-containing sealant was observed on the ridge cap of the sloped metal roofing. Samples of similar sealant located on screwheads, roof penetrations, metal flashing, and seams consistently tested negative for asbestos. The asbestos-containing roof sealant is very limited in quantity and only appears to be at the ridge cap.

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

Asbestos Regulations

Oregon DEQ, Environmental Protection Agency (EPA), and OSHA regulations require proper removal and handling of ACMs by licensed and trained asbestos abatement contractors prior to building renovations or demolition.

The EPA, DEQ, and OSHA all define ACM as any material containing more than 1% asbestos. Although materials equal to or less than 1% are not considered by regulatory agencies to be an ACM, they still have some asbestos content, and Oregon OSHA has 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.

In 1995, Oregon OSHA adopted 29 Code of Federal Regulations (CFR) Part 1926.1101 governing asbestos under

OAR 437-003-1926.1101. The regulation has made significant changes in work procedures and how asbestos materials are managed. OSHA believes that the single biggest risk of asbestos exposure is to workers who unknowingly or improperly disturb ACM. Hazard communication, training, personal protection, work practices, exposure monitoring, and recordkeeping are all major components of the regulation.

DEQ’s OAR 340, Division 248 also covers asbestos abatement requirements, removal notifications, licensing, and certifications for contractors.

For more information regarding the removal of ACMs, please refer to the following:

1. Oregon Occupational Safety and Health Administration, OAR 437-003-1926.1101

2. Department of Environmental Quality, OAR-340, Division 248

LEAD-BASED PAINT

The building exterior is unpainted brick. Paint chip samples were collected from representative interior painted building components. The samples represent the major painted components of the building. The paint samples were submitted under chain of custody to RJ Lee Group in Monroeville, Pennsylvania, for lead analysis by flame atomic absorption (FLAA).

The paint samples tested below the limit of detection for lead. Painted surfaces were observed in good condition throughout the building. No lead-based paint hazards were identified.

For reference, the EPA uses 5,000 parts per million (ppm) as the threshold limit for the definition of lead -based paint. However, lead in any concentration may become airborne above the OSHA action level during certain trigger activities. Lead-safe work practices should always be employed when impacting paint that contains lead in any concentration.

Refer to the lead sample inventory for specific lead paint sample locations and the associated lead concentrations.

Lead-Containing Paint Regulations

The Consumer Product Safety Commission limit for lead in consumer paint products is 0.009% or 90 ppm or greater. The Department of Housing and Urban Development (HUD) and the EPA define lead-based paint as that which contains 0.5% or 5,000 ppm. Under OSHA, any lead concentration in paint that may become airborne during construction operations triggers requirements in the OSHA Lead in Construction Standard 29 CFR 1926.62 to protect employees impacting the paint.

In 1993, Oregon OSHA adopted the federal OSHA Lead Standard for the Construction Industry Title 29 CFR

1926.62 under Oregon Administrative Rule 437 Division 3 1926.62. This standard outlines worker exposure limits, personal protection requirements, and employer responsibility for exposure assessment, training, housekeeping, and recordkeeping. OSHA’s lead standard applies to all work where employees may be exposed to lead in construction, alteration, or repair activities. This includes demolition or renovation of structures where lead -containing materials are present.

Disposal

According to DEQ’s Hazardous Waste/Toxics Reduction Policy Clarification, disposal of building demolition waste coated with lead-based paint generally will not require a hazardous waste determination (i.e., Toxicity

Characteristic Leaching Procedures [TCLP] testing) if demolition debris is disposed of at a DEQ -permitted solid waste landfill that meets the current design standards for municipal solid waste disposal facilities of 40 CFR Part

258.

Refer to the DEQ hazardous waste reduction policy and follow all requirements under the DEQ, Management of

Building Demolition Waste, 97-002A for proper disposal of lead-based painted demolition waste.

PCB/MERCURY VAPOR TUBES

MERCURY LAMPS AND POLYCHLORINATED BIPHENYLS (PCBS) SUMMARY

Fluorescent light fixtures that appear to use mercury-containing lamps are present throughout. However, close inspection revealed that the light tubes are LED. LED fixtures do not use polychlorinated biphenyl (PCB) containing ballasts.

Although the lighting appeared to be upgraded to LED, care should be taken if lamps are to be removed to ensure that legacy mercury-containing lamps are not present in isolated fixtures.

Fluorescent mercury vapor light tubes are categorized as a universal waste. They should be carefully handled, packaged, and recycled or disposed of appropriately according to guidelines stipulated under 40 CFR 273.

BULK POLYCHLORINATED BIPHENYLS SUMMARY

Samples of exterior building sealants, suspected of containing PCBs, were collected. The samples revealed no concentrations of PCBs.

Remove material as needed in conjunction with facility improvements.

The test report shall not be reproduced except in full, without written approval of the laboratory. The report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST, or any agency of the federal government. The Company reserves the right to dispose of all samples after a period of thirty (30) days, according to all state and federal guidelines, unless otherwise specified.

Inhomogeneous samples are separated into homogeneous subsamples and analyzed individually. ND means no fibers were detected. When detected, the minimum detection and reporting limit is less than 1% unless point counting is performed. Floor tile samples may contain large amounts of interference material and it is recommended that the sample be analyzed by gravimetric point count analysis to lower the detection limit and to aid in asbestos identification.

‡ A "Version" indicated by -"x" after the Lab ID# with a value greater than 1 indicates a sample with amended data. The revision number is reflected by the value of "x".
