RE: PRE-RENOVATION ASBESTOS AND LEAD-IN-PAINT

INSPECTION - BUILDING 610, MAFB

MAFB OPPORTUNITY NO. 1053500

TD&H ENGINEERING JOB NO. 19-047-070

Dear Mr. Kaltenbach, In accordance with our Agreement for Engineering Services, TD&H Engineering, Inc.

(TD&H) performed a pre-renovation asbestos and lead-in-paint inspection of Building 610, located on MAFB, on May 22nd and 23rd, 2019. The asbestos and lead-in-paint inspections were performed in accordance with the Statement of Work (SOW) as detailed in the August 13th, 2018, document entitled "Add/Alt OSI, Bldg. 610”, Opportunity No. 1053500. This asbestos inspection report must be kept on site during all renovation activities.

PROJECT DESCRIPTION

The building is an approximately 7,200-square-foot, single-story building with a slab-on-grade foundation commonly known as Building 610. The floors are bare concrete or are covered by floor tile, ceramic tile, or carpet. Walls are either concrete masonry unit (CMU) or wood-framed and covered by drywall or ceramic wall tile. The ceilings are drywall or covered by a lay-in ceiling panel system.

Building 610 is scheduled to undergo possible renovations to meet the needs of the Air Force Office of Special Investigations (AFOSI) in fulfilling their mission. Asbestos and lead-in-paint inspections are required prior to the start of any renovation activities.

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. The National Emissions Standards for Hazardous Air Pollutants (NESHAP – 40 CFR 61) and the ARM regulate asbestos due to the respiratory hazard that airborne asbestos fibers present. The inspection was performed by Mr. Deven Vignali and Ms. Laura Hart of TD&H, both Montana-accredited asbestos inspectors, 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 A.

June 21, 2018 PAGE NO. 2 t d h e n g i n e e r i n g . c o m

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: Three samples for spray-applied and trowel-applied surfacing materials between 10 and 1,000 square feet (SF), five samples for surfacing materials between 1,000 and 5,000 SF, and seven samples for surfacing materials over 5,000 SF.

• Thermal System Insulation: Three samples from each HA of thermal system insulation, which may include 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 10 SF: 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.

A total of 31 suspect building materials were identified during the inspection. Bulk samples were collected from the materials 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), located in Baton Rouge, Louisiana, for analysis 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 Accreditation 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%.

Three locations in the exterior CMU walls and two locations in the interior CMU walls were inspected for vermiculite insulation. No vermiculite was encountered, and the wall cavities had been filled with grout.

All the samples collected during the inspection were determined by laboratory analysis to be non-asbestos containing and were listed in the report as “None Detected”. These HAs are shown in Table 1. The analytical report provided by CA Labs is provided in Appendix B, and sample locations are shown on Figure 1 in Appendix C.

LEAD-BASED PAINT INSPECTION

A lead-based paint (LBP) survey was conducted to identify painted components that may require specialized handling to comply with Occupational Safety and Health Association (OSHA) requirements or special disposal under the Resource Conservation and Recovery Act (RCRA), which is administered by the EPA. The survey was performed by an experienced technician with training as an LBP risk assessor.

Lead-Based Paint LBP is of concern both as a source of direct exposure through ingestion of paint chips and as a contributor to lead in interior dust and exterior soil. Regulatory agencies which have addressed lead-based paint include the EPA, Department of Housing and Urban Development (HUD), OSHA, and the Consumer Products Safety Commission (CPSC).

There is no state program for lead.

HUD guidelines define lead-based paint as:

• Paint in liquid form which contains 0.06%, by weight, calculated as lead metal in total nonvolatile content of the liquid paint, or

• Paint already applied which tests equal to or greater than 1.0 milligrams per square centimeter (mg/cm2) when using X-Ray Fluorescence (XRF) technology, or 5,000 milligrams per kilogram (mg/kg) (0.5% by weight) when using atomic absorption spectroscopic analysis (AA).

Lead-Containing Paint The term “lead-containing paint” (LCP) is used for paint that contains lead at concentrations less than the HUD guidelines or EPA disposal regulations. The OSHA standard for lead in the construction industry does not recognize a minimum safe concentration of lead. If any painted surface has any detectable level of lead, it must be presumed to present an occupational exposure to lead for OSHA-regulated construction work until a negative exposure assessment or exposure monitoring establishes otherwise.

June 21, 2018 PAGE NO. 5

Methods A Niton X-ray fluoroscope (XRF) was used to test paint for lead. The XRF instrument provided a real concentration of LBP based on the generated spectra and an algorithm programmed into the instrument. The XRF was standardized prior to the start, at mid-day, and after the conclusion each day of LBP surveying against lead-based paint standards provided by the manufacturer of the XRF.

Painted surfaces were placed into HAs by identical colors, substrates, and building component types.

Results One HA tested positive for lead-based paint, and nine HAs were analyzed as lead-containing and are shown in Table 2. Results of all painted surfaces analyzed are contained in Appendix D, and XRF sample locations are shown in Appendix E.

RECOMMENDATIONS

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

Asbestos Since none of the materials suspect for asbestos were determined by laboratory analysis to be ACM, no further action is required regarding asbestos. Additional sampling may be necessary if site activities expose other suspect materials not described in this report.

June 21, 2018 PAGE NO. 6

Lead Work involving components covered with paint containing lead is governed by OSHA regulations. Disposal of lead, paint containing lead or building materials covered with paint containing lead is governed by EPA regulations.

Environmental Protection Agency. EPA’s Lead-Based Paint Renovation, Repair and Painting Program Rule contained in 40 CFR Part 745, Subpart E, requires workers to be trained to use lead-safe work practices and requires renovation firms to be EPA-certified;

these requirements became effective April 22, 2010. Since the building involved in the renovation is not a child occupied facility or pre-1978 housing, only the EPA regulations described below will apply.

EPA Regulations for Disposal of Lead-Based Paint Components. When a waste stream with a concentration of 5 milligrams per liter or more when tested using the Toxicity Characteristic Leaching Procedure (TCLP) exceeds the Resource Conservation and Recovery Act (RCRA) TCLP Rule (40 CFR 261.24) regulatory standard for hazardous waste disposal, then disposal of lead-based painted components will require specialized handling and disposal in landfills classified to accept the hazardous waste. LPB surfaces should not be sanded or handled in such a way that lead could be liberated from the painted surfaces.

Occupational Safety and Health Administration. The lead-based and lead-containing surfaces found in this survey are intact and if not disturbed do not present a hazard to employees involved in the renovation. If these components are disturbed in a manner such as described below, then a hazardous condition may result and will need to be addressed according to OSHA regulations.

The OSHA standard for Lead in Construction, 29 CFR 1926, does not recognize a safe level of lead in dried paint to which workers may be exposed in an occupational setting.

Consequently, any disturbance to painted surfaces which contain a measurable quantity of lead must be considered as having the potential to create a risk to workers.

The OSHA standard cites a Permissible Exposure Level (PEL) of 50 micrograms of lead per cubic meter of air (μg/m3) and an Action Level (AL) of 30 μg/m3. Any amount above these levels triggers several safety and health provisions, including, but not limited to:

1. A respiratory protection program

2. Personal protective clothing and equipment

3. Changing areas including segregated storage of work and non-work clothing

4. Hand-washing facilities

5. Blood testing

6. Employee training

Also, if an employee is performing any of the following tasks:

1. Manual demolition, dry scraping, or dry sanding

2. Heat gun applications

3. Power tool cleaning

4. Other industrial operations involving lead as specified in the OSHA standards, then all of the above-mentioned safety items must be provided to the employees. If it is found that either the AL or the PEL is being exceeded, then other safety requirements must be met.

June 21, 2018 PAGE NO. 7

A negative exposure assessment (NEA) should be completed on employees that are performing the work. The NEA would ensure that good work practices may prevent employee exposure to elevated concentrations of airborne lead. The NEA should be performed on the same employees, using the same methods and using the same tools that will be used for the duration of the project.

Recommended Response Actions. TCLP sampling of the waste stream may be required by

High Plains Sanitary Landfill which serves the Great Falls area if LBP is present. If results are greater than 5.0 milligrams per liter, either removal of LBP or chemical fixation may be needed. If neither of these solutions is practical, the components must be disposed of in a

Class I landfill.

Any work with LBP and LCP that has the potential to expose workers to airborne lead at or above the PEL should be performed by a certified lead abatement contractor.

LIMITATIONS

This asbestos and lead-in-paint inspection report was prepared based on information gathered during two site visits and interpretations of laboratory analytical results provided by CA Labs. The inspection report has been prepared to provide information concerning the various types of building materials that were considered suspect for containing asbestos or lead-in-paint and to inform you of which building materials tested positive.

Most building components were visible and accessible at the time of our site visits.

However, additional suspect materials may be encountered during renovation activities.

TD&H should be contacted if work will disturb materials in addition to those included in this report. TD&H may need to be present during work activities if the potential exists to disturb materials that were not accessible during our site work.

This asbestos and lead-in-paint inspection report is intended for use by Coffman Engineering, Inc. and its clients. The scope of services performed by TD&H Engineering 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.

Qualifications

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.

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.

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.

Materials Characterization - Bulk Asbestos Analysis

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.
