1.0 INTRODUCTION

BGES, Inc. (BGES) was retained by the Yukon River Inter-Tribal Watershed Council (YRITWC) to conduct a limited Hazardous Building Materials Inventory (HBMI) of the buildings located at 400 C Street in Beaver, Alaska (hereafter referred to as the “subject property”). The purpose of this assessment was to evaluate the potential presence of hazardous building materials, such as lead-based paint (LBP) and asbestos-containing building materials (ACBM), within the buildings on the subject property.

Photographs of the subject property, and selected sampling/testing locations at the subject property, are included in Appendix A.

This report presents the results of our findings. The presence of LBP was evaluated using an x-ray fluorescence (XRF) field screening instrument, and asbestos was evaluated by collecting samples of potential ACBM (PACBM) and submitting this material to an accredited laboratory for analysis. LBP data and asbestos laboratory results are included in Appendix B.

The limited HBMI was performed during May of 2022. The inspections were performed by Carson Kent, Environmental Scientist II of BGES. Mr. Kent is an AHERA-Certified Building Inspector (Certificate #

TBI24-220-13779) and a United States (U.S.) Environmental Protection Agency (EPA)-Certified Risk

Assessor (Cerificate # LBP-R-I219617-1). Copies of BGES’ certificates are included in Appendix C.

A total of 195 XRF readings were taken from all identified different testing combinations in the inspected areas of the buildings on the subject property from interior and exterior portions of the structures. Testing combinations are comprised of rooms (or room equivalents), building components, and substrates. Thirty-two of the readings, taken from walls and ceilings; porch components; window components within one bedroom, the outbuildings, and within the attic; and exterior doors located on the south side of the building and on the outbuildings, exceeded the EPA regulatory limit of 1.0 milligram (mg) of lead per square centimeter (cm2), or 1.0 mg/cm2.

A total of 92 bulk samples (39 samples with 53 additional layers) were collected from PACBM identified in the inspected areas/locations at the property. The samples were sent to an accredited laboratory and were analyzed using Polarized Light Microscopy (PLM), in accordance with EPA Method 600/R-93/116.

According to the National Emissions Standard for Hazardous Air Pollutants (NESHAP), Asbestos-

Containing Materials (ACMs) are defined as containing at least 1 percent asbestos including, but not limited to, chrysotile, amosite, tremolite, actinolite, and crocidolite asbestos. Samples were collected from wall material, insulation, ceiling material, resilient flooring material, carpet mastic, joint compound, and cove base molding and mastic. Twenty-one of the sample layers collected in the buildings on the subject

Beaver Old Schoolhouse Page 2 of 8 21-090-01 Beaver, AK; Limited HBMI property, from linoleum located within the foyer, hallway, kitchen, bathroom, classrooms, housing kitchen, and bedroom closet; from mastic located on the foyer floor, hallway transition strip, hallway floor, and kitchen cabinets; and from joint compound used throughout the building were found to be “asbestos-containing” according to the NESHAP definition, and the remaining samples were not found to be

“asbestos-containing” according to the NESHAP definition.

Applicable regulations regarding the abatement and disposal of ACM and LBP are described in Section 5.

XRF data and laboratory analytical data pertaining to the PACBM samples are included in Appendix B.

2.0 SITE DESCRIPTION AND SAMPLING TECHNIQUES

The subject property contains a two-story building, currently not in use but used historically as a schoolhouse and as a elder center, which totals approximately 6,000 square feet in size. The building, containing two classrooms, a kitchen, an office, a shower room, a restroom, and several closets as well as an attic and a living space comprising of two bedrooms, a dedicated bathroom, and a combined kitchen/living room was inspected for the presence of LBP and asbestos. Lead sampling was performed by utilizing a Heuresis Pb200i XRF Lead Analyzer to test for the presence of lead in selected painted surfaces. This was accomplished in general accordance with established Department of Housing and

Urban Development (HUD) & EPA guidelines. Sampling of building materials for asbestos content analysis was conducted by removing a small sample of the suspected material, including all associated substrates, with a hammer and chisel. The samples were then placed into sealable plastic bags and sealed for shipment to the laboratory. Samples for laboratory analysis were clearly labeled and submitted to the laboratory under chain of custody protocol.

3.0 ACBM AND LBP SAMPLING AND ASSESSMENT

3.1 Description of Assessment

The LBP and PACBM assessments were conducted on May 11, 2022. The walkthrough assessment included a visual inspection of the buildings and collection of LBP data and PACBM samples. This inspection included the collection of building materials such as wall material, insulation, ceiling material, resilient flooring material, carpet mastic, joint compound, cove base molding and mastic.

3.2 PLM and XRF Analytical Techniques

Painted surfaces were analyzed using a Heuresis Pb200i XRF Lead Analyzer. For a complete description of the XRF testing method, please refer to the 1997 HUD Inspection Protocol.

Beaver Old Schoolhouse Page 3 of 8 21-090-01 Beaver, AK; Limited HBMI

PACBM representative bulk samples collected during our inspection activities were analyzed for asbestos content by EMSL Analytical, Inc., a laboratory accredited by the National Institute of Standards and

Technology (NIST), and approved by the National Voluntary Laboratory Accreditation Program

(NVLAP). For a complete description of the PLM method, please refer to EPA Method 600/R-93/116 and

Title 40 Code of Federal Regulations (CFR) Part 763 Appendix A to Subpart E, Section 1.

4.0 RESULTS

The results of the XRF analyses of painted surfaces and PLM analyses of PACBMs are listed below.

4.1 XRF Analysis Results

A total of 195 XRF readings were taken from all identified different testing combinations in the inspected areas of the buildings on the subject property from interior and exterior portions of the structures. Testing combinations are comprised of rooms (or room equivalents), building components, and substrates. Thirty-two of the readings, taken from walls and ceilings; porch components; window components within one bedroom, the outbuildings, and within the attic; and exterior doors located on the south side of the building and on the outbuildings (Photographs 1 through 32 in Appendix A), exceeded the EPA regulatory limit of

1.0 mg/cm2.

Positive XRF reading locations are depicted on Figures 1, 2, and 3 and XRF analytical data are summarized in Table 1.

4.2 PLM Analytical Results

A total of 92 bulk samples (39 samples with 53 additional layers) were collected from PACBM identified in the inspected portions of the buildings on the subject property. Each sample was analyzed by EPA

Method 600/R-93/116. As described above, according to the NESHAP, ACMs are defined as containing at least 1 percent asbestos. Samples were collected from wall material, insulation, ceiling material, resilient flooring material, carpet mastic, joint compound, cove base molding, and mastic. Twenty-one of the sample layers collected in the buildings on the subject property were found to be “asbestos-containing” according to the NESHAP definition, and the remaining samples were not found to be “asbestos-containing” according to the NESHAP definition.

The 21 samples found to be “asbestos-containing” according to the NESHAP definition were from linoleum located within the foyer, hallway, kitchen, bathroom, classrooms, housing kitchen, and bedroom closet; from mastic located on the foyer floor, hallway transition strip, hallway floor, and kitchen cabinets;

and from joint compound used throughout the building (Photographs 33 through 51 in Appendix A).

5.0 APPLICABLE REGULATIONS AND GUIDELINES

5.1 Lead-Based Paint For Federally Owned Or Assisted Housing (Sections 1012 & 1013)

On September 15, 1999, HUD published final regulations to implement Sections 1012 & 1013 of Title X, which set forth specific policies on LBP hazard reduction in federally assisted and federally owned housing

(24 CFR Part 35 — Requirement for Notification, Evaluation and Reduction of Lead-Based Paint Hazard in Housing Receiving Federal Assistance). This rule is a comprehensive amendment of previous federal housing LBP regulations and consolidates HUD LBP requirements into one part of the CFR. HUD guidelines are applicable for a dwelling that contains LBP at 1.0 mg/cm2 or more. In most cases, HUD guidelines also require disclosure of the presence of LBP in building materials to any future tenants or owners of the property.

5.2 U.S. EPA’s Renovation, Repair, & Painting (RRP) Rule (40 CFR 745 Subpart E)

Between 2008 and 2013, the U.S. EPA promulgated the RRP guidelines pertaining to renovation, repair, and painting projects that disturb lead-based paint in homes, child care facilities and pre-schools built before 1978, and it requires contractors to have their firm certified by EPA (or an EPA-authorized state), use certified renovators who are trained by EPA-approved training providers and follow lead-safe work practices.

5.3 US EPA NESHAP Regulations

According to the NESHAP standards, before general demolition or renovation activities within buildings containing asbestos can occur, identified friable and some categories of non-friable ACBMs must be properly encapsulated or abated, as prescribed by NESHAP regulations. NESHAP categorizes ACM analyzed by the PLM method into two main types, friable and non-friable ACM. Friable ACM is a material that when dry, can be crumbled, pulverized, or reduced to powder by hand pressure. Non-friable ACM is further delineated by two different Categories, Category I and Category II non-friable ACM. Category I non-friable ACM is defined as asbestos-containing packing, gaskets, resilient floor covering, and asphalt roofing product. Category II non-friable ACM is any material, excluding Category I non-friable ACM that when dry cannot be crumbled, pulverized, or reduced to powder by hand pressure. NESHAP considers friable ACM, Category I non-friable ACM, and Category II non-friable ACM that is exposed to certain conditions (discussed below), to be Regulated Asbestos Containing Material (RACM). Notification to the

Beaver Old Schoolhouse Page 5 of 8 21-090-01 Beaver, AK; Limited HBMI

U.S. EPA or the state is required before a building containing RACM is demolished or renovated. A material is considered RACM if it fits these criteria:

• Friable ACM.

• Category I non-friable ACM that has been or will be exposed to forces during demolition or removal that may disturb the material and cause it to become friable. This includes, but is not limited to, grinding, cutting, sanding, and abrading.

• Category II non-friable ACM that has been or will be exposed to forces during demolition or renovation that may disturb the material, causing it to become crumbled, pulverized, or reduced to a powdered form.

According to NESHAP regulations, RACM need not be removed before demolition or renovation if it meets the following criteria:

• It is Category I non-friable ACM that is in good condition.

• It is enclosed in concrete or other similarly hard material and is adequately wet when it is exposed during demolition or renovation.

• The RACM was discovered after demolition or renovation began and it cannot be safely removed.

• It is Category II non-friable ACM and there is a low probability that the material will become disturbed during demolition or renovation.

5.4 OSHA Regulations CFR 1910 And 1926

OSHA’s permissible exposure limit (PEL) is 0.1 fiber per cubic centimeter (f/cc) of air as an 8-hour time-weighted average (TWA). The Excursion Limit is 1.0 f/cc averaged over a 30-minute period.

With the exception of agricultural activities, OSHA’s general industry standard regulates all activities related to asbestos that are not covered by the construction and shipyard employment standards. This standard requires employers to provide awareness training to employees who perform maintenance or housekeeping duties where ACM or presumed ACM is located. This includes a mandatory participation-training program for all employees who are exposed to airborne asbestos at or above the PEL and or

Excursion Limit. The program should be instituted and carried out before the employee’s initial exposure to the area and a refresher course must be offered annually.

Under OSHA’s construction standard, OSHA classifies construction activity according to descending degree of risk, with Class I work presenting the greatest potential risk and class IV the lowest.

Beaver Old Schoolhouse Page 6 of 8 21-090-01 Beaver, AK; Limited HBMI

• Class I work involves the removal of Thermal System Insulation (TSI) and surfacing ACM or PACM.

• Class II work involves removal of any other ACM that is not TSI or surfacing ACM.

• Class III work includes repair and maintenance activities where employees are likely to disturb ACM.

• Class IV work is defined as maintenance and custodial activities during which employees contact

ACM or PACM, including waste and debris cleanup.

Employers must institute a training program for all workers who install asbestos-containing products and all workers who perform Class I, II, III, or IV work. Medical surveillance is required for all workers who engage in class I, II, or III work for a combined total of 30 days or more per year. Medical surveillance is also required for those who are exposed above the PEL or the excursion limit of 1.0 f/cc. Employers and building owners must communicate the hazard to employees and the contractors when ACM or PACM is present in their facilities or if their employees will work with ACM.

OSHA requires a competent person to be designated by the employer. The competent person must have qualifications and the authority for ensuring worker health and safety. This includes identifying existing asbestos hazards in the workplace and selecting the appropriate control strategy to reduce asbestos exposure with the authority to take prompt corrective action. Class I and Class II construction work requires the USEPA’s Model Accreditation Plan (40 CFR 763) training or its equivalent for the project designer or supervisor. Class III and Class IV construction work requires completion of a 24-hour

Operation and Maintenance (O&M) course developed by the U.S. EPA (40 CFR 763.93) or its equivalent.

The duties of the competent person include regular inspections of the job site, equipment, and materials as part of the required safety and health program.

6.0 CONCLUSIONS AND RECOMMENDATIONS

A total of 195 XRF readings were taken from all identified different testing combinations in the inspected areas of the buildings on the subject property from interior and exterior portions of the structures. Testing combinations are comprised of rooms (or room equivalents), building components, and substrates. Thirty-two of the readings, taken from walls and ceilings; porch components; window components within one bedroom, the outbuildings, and within the attic; and exterior doors located on the south side of the schoolhouse building and on the outbuildings, exceeded the EPA regulatory limit of 1.0 mg/cm2.

A total of 92 bulk samples (39 samples with 53 additional layers) were collected from PACBM identified in the inspected portions of the buildings on the subject property. Twenty-one of the sample layers were found to be “asbestos-containing” according to the NESHAP definition. Linoleum located within the

Beaver Old Schoolhouse Page 7 of 8 21-090-01 Beaver, AK; Limited HBMI foyer, hallway, kitchen, bathroom, classrooms, housing kitchen, and bedroom closet was found to contain between 3 percent and 20 percent chysotile asbestos; mastic located on the foyer floor, hallway transition strip, hallway floor, and kitchen cabinets was found to contain between 5 percent and 7 percent chrysotile asbestos; and joint compound used throughout the building was found to contain between 2 percent and 3 percent chrysotile asbestos.

The linoleum flooring materials in the foyer, hallway, kitchen, bathroom, classrooms, housing kitchen, and bedroom closet and the mastics on the foyer floor, hallway transition strip, hallway floor, and kitchen cabinets should be considered Category II non-friable ACMs. The joint compound present in the walls and ceilings throughout the building, as represented by these samples, should be considered to be friable

ACM, and is therefore RACM, as defined by NESHAP.

While an industry and regulatory-accepted method, use of the PLM method without a point count (for example the 400 or 1,000 point count) may result in estimated asbestos concentrations that are higher or lower than the material’s actual asbestos content. Other analytical procedures (for example, cleanup of the sample via gravimetric reduction) may also improve the accuracy of the laboratory results.

The conclusions and recommendations presented in this report are based on prevailing site conditions during the sample collection period. The inspector did not demolish walls, chases, or any other building spaces while performing this assessment. Consequently, ACMs and LBP may be present in other areas that were not inspected during this survey.

This report was prepared for our client, YRITWC. The scope of work was defined in our written proposal dated September 27, 2021. It is not intended for third parties to rely on the information provided in this report, except at their own risk.
