RE: PRE-RENOVATION ASBESTOS INSPECTION

THE PA OFFICE, BUILDING 500

MALMSTROM AIR FORCE BASE, MONTANA

TD&H ENGINEERING JOB NO. 24-083-071

Dear Mr. Grundhauser, TD&H Engineering (TD&H) understands Malmstrom Air Force Base (MAFB) plans to repair the floor of the PA Office within Building 500. TD&H performed an asbestos inspection on the building materials on May 2, 2024. This asbestos inspection report must be kept on site during renovation activities. A summary of the asbestos inspection is provided in Appendix A. The Montana Department of Environmental Quality (MDEQ) has recently issued new rules and TD&H has made their best effort to incorporate these rules into new and existing projects.

ASBESTOS INSPECTION

The Administrative Rules of Montana (ARM) 17.74.354 require an asbestos inspection be completed for all building materials prior to scheduled renovation activities to determine if asbestos-containing materials (ACM) are present. ACM is defined as any material or product that contains more than 1% asbestos. The National Emissions Standards for Hazardous Air Pollutants [NESHAP – 40 Code of Federal Regulations (CFR) 61], the Occupational Safety and Health Administration (OSHA), and the ARM regulate asbestos due to the respiratory hazard that airborne asbestos fibers present. The inspection was performed by Mr. Kyle A.

Groves of TD&H, a Montana-accredited asbestos inspector, in accordance with the Environmental Protection Agency (EPA) – Asbestos Hazards and Emergency Response Act (AHERA) regulation 40 CFR 763. Documentation of accreditation is provided in Appendix B.

Building materials were identified, categorized, numbered, and placed into homogeneous areas (HAs) for sample collection and laboratory analysis. The number of samples collected from building materials identified during the inspection is based on the following:

• Surfacing Materials: At least three samples for surfacing materials that are 1,000 square feet (SF) or less, at least five samples for surfacing materials that are greater than 1,000 SF but less than or equal to 5,000 SF, and at least seven samples for surfacing materials that are greater than 5,000 SF.

May 6, 2024 PAGE NO. 2

• Thermal System Insulation: Three samples from each HA of thermal system insulation, which may include but is not limited to boiler insulation, mudded fittings, and expanded vermiculite insulation.

• Miscellaneous Materials: Three samples from each HA of miscellaneous material, such as ceiling tile, wallboard system, cove base mastic, floor tile and mastic, concrete, roofing materials, and brick mortar.

• Materials Less Than Regulated Quantities: At least one sample from each HA of patching material, such as replacement floor tiles or patching plaster, and materials of less than 10 SF in total area, which are not subject to regulation by the MDEQ but may still trigger OSHA requirements.

A total of five suspect building materials were identified during this inspection. Bulk samples were collected from the building in accordance with the currently recognized standard protocol developed under AHERA. Bulk samples were placed into containers and shipped to CA Labs, LLC (CA Labs) in Baton Rouge, Louisiana, for analysis in accordance with the approved QAPP SOP 18 using Polarized Light Microscopy (PLM) in accordance with the EPA Method 600/R-93/116. CA Labs is accredited through the National Institute of Standards and Technology’s (NIST) National Voluntary Laboratory Accred itation Program (NVLAP). The point-counting technique employed by CA Labs in the analysis of these samples has a limit of detection of approximately 0.1% by volume on samples that contained asbestos at concentrations under 1%.

One HA sampled during the inspection was determined by laboratory analysis to contain asbestos in quantities greater than 1%, as shown in Table 1 below. The analytical report provided by CA Labs is provided in Appendix C. Sample identification and locations are shown on Figure 1 in Appendix D.

Also shown in Table 1 is a Condition Ranking as detailed in the Malmstrom Air Force Base

Asbestos Management and Operations Plan. The plan lists four rankings as provided by Mr.

Robert Richards. These are detailed below:

• Ranking 1: Asbestos is damaged and poses a health hazard.

• Ranking 2: Asbestos is damaged but does not pose an immediate health hazard.

• Ranking 3: Asbestos is in good condition, does not pose a hazard, but is vulnerable to damage or wear.

• Ranking 4: Asbestos is in good condition and does not pose a hazard under normal conditions.

Following receipt of the laboratory report, building materials containing asbestos were placed into one of the following three categories using NESHAP criteria:

• Category I: Non-friable 1 asbestos-containing packings, gaskets, resilient floor coverings, and asphalt roofing products – all containing more than 1% asbestos.

• Category II: All non-friable materials containing more than 1% asbestos except those found in Category I.

• Regulated Asbestos-Containing Materials (RACM): Friable materials, Category I non-friable materials that will or may be subjected to sanding, grinding, cutting, or abrading; or Category II non-friable materials that have a high probability of becoming or have become crumbled, pulverized, or reduced to powder by forces expected to act on the material in the course of renovation/renovation operations.

According to NESHAP regulation 40 CFR 61.145 (c)(1)(i) and ARM 17.74, any RACM or Category I or II ACM that may be rendered friable during renovation or renovation activities must be properly abated prior to beginning the project, which must be overseen by someone with training as a “competent person” per OSHA. NESHAP also requires that any renovation or renovation activities be free of visible dust or fugitive emissions from any regulated substances, including asbestos. All building materials should be adequately wetted to

1 Friable means able to be crushed or reduced to powder by hand pressure when dry, or similarly broken or pulverized mechanically.

May 6, 2024 PAGE NO. 4 prevent the release of particulate. Depending on the type of renovation planned, OSHA and state regulations may require personal air monitoring and the use of engineering controls.

It is a requirement under NESHAP regulations that at least ten working days prior to an asbestos abatement project, a written notification must be provided to the EPA. In the State of Montana, notification of asbestos abatement is sent to the MDEQ, Permitting and Compliance Division – Asbestos Control Program.

RECOMMENDATIONS

The following recommendations for materials containing asbestos are based on our observations and the anticipated scope of renovation.

One area of ACM was identified.

The Category I black and tan mastic was non-friable at the time of the inspection and, if maintained in a non-friable state, may be removed in an unregulated fashion under state and federal law. Any grinding sawing, abrading, or pulverizing of the Category I or Category II -containing material will render those materials friable and regulated (RCAM).

Per OSHA, asbestos removal for Category I or II ACM in a non-friable “intact” condition must be overseen by a “competent person” holding current Montana accreditation as an Asbestos Contractor/Supervisor. If these materials are removed in a non-friable manner, asbestos abatement permitting will not be required. Limited air monitoring may be necessary for OSHA compliance.

Asbestos abatement for RACM must be performed by a Montana-accredited abatement contractor. All personnel involved in the disturbance or removal of building components assumed to contain asbestos, or identified as asbestos containing, must be trained according to the requirements set forth in 29 CFR 1926.1101 (k)(9) and 75-2-511, Montana Code Annotated (MCA).

The MDEQ considers all categories of asbestos-containing material to be “special waste” under Montana Solid Waste Rules. Transport of RACM waste is regulated and will require a permit. RACM waste must also be segregated from the general renovation waste for disposal in the designated asbestos disposal area at a local landfill that is licensed to accept asbestos-containing material. Many landfills require that all categories of ACM be segregated from the general demolition waste stream. RACM must be double-bagged or double-wrapped in 6-mil plastic sheeting; non-RACM may be single-wrapped. All material must be wrapped “burrito style” with taped seams. The name and contact information of the owner must be provided on each waste package. We recommend that potential landfills be contacted prior to bidding or disposal for clarification of disposal requirements.

Malmstrom Air Force Base Asbestos Management and Operations Plan as described above also includes recommendations for performing Operations and Maintenance (O&M) for each

HA identified as ACM. The recommendations as supplied by Mr. Richards are as follows:

May 6, 2024 PAGE NO. 5

• Ranking 1: Coordinate immediate removal or abatement.

• Ranking 2: Qualified personnel to control or encapsulate as soon as possible.

• Ranking 3: Schedule periodic re-inspection to ensure the area remains stable. This applies particularly to potentially friable asbestos, such as mechanical room TSI.

• Ranking 4: Schedule periodic re-inspection to ensure the area remains stable.

As listed in Table 1, the ACM received a Condition 4 Ranking. The recommended O&M ranking will also be Ranking 4.

LIMITATIONS

This asbestos inspection report was prepared based on information gathered during one site visit and interpretations of laboratory analytical results provided by CA Labs. The inspection report is intended to provide information concerning the various types of building materials that were considered suspected of containing asbestos and to inform MAFB of which building materials tested positive.

Most building components were visible and accessible at the time of our site visit. Additional suspect materials may be encountered during renovations activities. If work will disturb materials in addition to those included in this report, TD&H should be contacted and may need to be present during these activities.

This asbestos inspection report is intended for use by MAFB and their clients. The scope of services performed by TD&H may not be appropriate to satisfy the needs of other users, and any use or re-use of this document, or the findings presented herein, is at the sole risk of the user.

Analysis and Method

Discussion

Qualifications

Some samples (floor tiles, surfacings, etc.) may contain fibers too small to be detectable by PLM analysis and should be analyzed by TEM bulk protocols.

A "trace asbestos" will be reported if the analyst observes far less than 1% asbestos. CA Labs defines "trace asbestos" as a few fibers detected by the analyst in several preparations and will indicate as such under these circumstances.

Quantification of <1% will actually be reported as <=1% (allowable variance close to 1% is high). Such results are ideal for point counting, and the technique is mandatory for friable samples (NESHAP, Nov. 1990 and clarification letter 8 May 1991) under 1% percent asbestos and the "trace asbestos". In order to make all initial PLM reports issued from CA Labs NESHAP compliant, all <1% asbestos results (except floor tiles) will be point counted at no additional charge.

CA Labs is accredited by the National Voluntary Accreditation Program (NVLAP) for selected test methods for airborne fiber analysis (TEM), and for bulk asbestos fiber analysis (PLM). All analysts have a college degree in a natural science (geology, biology, or environmental science) or are recognized by a state professional board in one these disciplines .Extensive in-house training programs are used to augment education background of the analyst. The group leader of polarized light has received supplemental McCrone Research training for asbestos identification. This report is not covered by the scope of AIHA accreditation. Analysis performed at CA Labs, LLC 12232 Industriplex, Suite 32 Baton Rouge, LA 70809.

Summary of polarizing light microscopy (PLM / Stereomicroscopy bulk asbestos analysis) using the methods described in 40CFR Part 763

Appendix E to Subpart E (Interim and EPA 600 / R-93 / 116 (Improved). The sample is first viewed with the aid of stereomicroscopy. Numerous liquid slide preparations are created for analysis under the polarized microscope where identifications and quantifications are preformed. Calibrated liquid refractive oils are used as liquid mouting medium. These oils are used for identification (dispersion staining). A calibrated visual estimation is reported, should any asbestiform mineral be present. Other techniques such as acid washing are used in conjugation with refractive oils for detection of smaller quantities of asbestos. All asbestos percentages are based on calibrated visual estimation traceable to NIST standards for regulated of asbestos. Traceability to measurement and calibration is achieved by using known amounts and types of asbestos from standards where analyst and laboratory accuracy are measured. As little as 0.001% asbestos can be detected in favorable samples, while detection in unfavorable samples may approach the detection limit of 0.50% (well above the laboratory definition of trace).

Vermiculite containing samples may have trace amounts of actinolite-tremolite, where not found be PLM should be analyzed using TEM methods and / or water separation techniques. Suspected actinolite/vermiculite presence will be indicated through the sample comment section of this report.

Fibrous talc containing samples may even contain a related asbestos fiber known as anthophyllite. Under certain conditions the same fiber may actually contain both talc and anthophyllite (a phenomenon called intergrowth). Again, TEM detection methods are recommended. CA Labs PLM report comments will denote suspected amounts of asbestiform anthophyllite with talc, where further analysis is recommended.
