The USDA Forest Service of Missoula, Montana, contracted Mountain Consulting Services, LLC (Mountain Consulting) to provide a good-faith asbestos materials and lead coatings survey for the 3-story; 39,000 ft²; Historic Building 26 located on the Fort Missoula facility addressed at 322 Fort Missoula in Missoula, Montana.

This project was conducted to facilitate new occupancy phased renovations for the Building 26 structure. The survey services included: Good-faith asbestos building materials survey; and, Good-faith lead coatings survey. No prior survey documentation was provided for this project.

The field survey activities for this project were conducted on March 5th & 6th of 2014 by Mr. Samuel W. Bailey Jr., MDEQ/AHERA Building Inspection MTA-3565; and, Mr. David A. Jones, Montana State/EPA Lead Risk Assessor MT-R-14998-2, of Mountain Consulting.

SURVEY DESCRIPTION

Building 26 is one of the two largest structures present with the Fort Missoula facility. The structure is a 2-story concrete, masonry & wood framed government use building built on a full concrete daylight basement foundation. The structure was originally built around 1910 with 1 generation of building addition construction and moderate interior renovation projects.

The facility is comprised of the original 27,300 square feet (ft²) 1910 3-story building; with an 11,700 ft² building addition construction era (3-story northeast & southeast wing ends) of the building. The facilities combined square footage that includes the original building and additions is approximately 39,000 ft².

Interior finishes consist of original plaster walls & ceilings with newer generations of gypsum wallboard systems and some ceramic wall tiling; suspended ceilings are either suspended lay-in-tiles or fastened to wood stringer tiles; floorings consist mostly of original 9” vinyl tiles either exposed, hidden under carpeting or hidden under wood sub-flooring & newer 12” vinyl tile system with some ceramic tiling.

Exterior finishes consist of plaster skim coated concrete walls with wood framed window & door units and ceramic tile roofing with membrane roofing on covered porch areas. Walls do not appear to be insulated and the attic space has rot wool type blown-in present over vermiculite insulations.

Heating is supplied by upgraded modern type natural gas fired steam boilers and cast iron room radiators. The building is not equipped with any localized air conditioning (HVAC) systems. Hot water is supplied by either electric or steam hot water tanks.

March 25, 2014 S-1 Mountain Consulting Services, LLC

The facility property is located in the western central light industrial portion of Missoula, Montana.

The structure is bounded by Fort Missoula G Road to the north, Fort Missoula F Road to the east, Building 24 to the south and Fort Missoula H Road to the west. The closest main arterials are US Highway 93 to the east and US Highway 12 to the south.

ASBESTOS SURVEY SUMMARY

Mountain Consulting performed destructive bulk materials testing of suspect building materials present throughout the facility, to determine the presence or absence of asbestos minerals. Mountain Consulting collected 165 bulk material samples from 52 different homogeneous suspect building materials or material systems identified during survey activities. Laboratory analysts sub-divided 15 submitted samples, and did not analyzed 2 submitted samples, resulting in a total of 178 samples analyzed for this project.

REGULATED ACM MATERIALS

The following homogeneous building materials were found to contain greater than one percent (>1%) asbestos content by laboratory analysis and are considered to be (Regulated ACM) requiring proper abatement prior to being impacted by renovation or demolition activities:

9”x 9” Vinyl Floor Tiling (VFT) (Green & Black in Colors-Checkered Pattern) located throughout the majority of the 1st and 2nd floors of the building either exposed, hidden under carpeting, hidden under vinyl sheet flooring (VSF), hidden under newer VFT or VSF & wood sub-flooring systems was found to contain asbestos. The class II, non-friable, miscellaneous materials contain 4-6% chrysotile asbestos. The total quantity of material present is 22,600 ft².

The quantities break for overlaid material types is as follow: There is approximately 1,360 ft² of this material exposed (1st floor NE office and the 2nd floor NE dormitory); approximately 5,780 ft² of this material present hidden under ACM-Free vinyl sheet flooring (VSF) (1st & 2nd floors; N & W wings); approximately 9,800 ft² of this material present hidden under carpeting (1st floor N, W & S wings; 2nd floor N & W wings); and, approximately 5,660 ft² of this material present hidden under ACM-Free VFT or VSF and wood sub-flooring (1st floor S wing hallway & 2nd floor entire S wing). It should be noted that the associated black flooring mastic material was proven to be ACM-free. Represented by bulk samples 14-037.1-72, 73 & 74.

Exposed Silver Painted Tar Coating Layers associated with the built-up tar adhered corkboard wall paneling system present within the old cooler rooms of the northeast and southeast center end rooms of the 1st floor within the building was found to contain asbestos.

The class II, non-friable, miscellaneous coatings material contains 7-10% chrysotile asbestos. It should be noted that this material is present with the walls, ceilings and assumed to be present under the elevated concrete floors within each room. Also the interior of southeast wing cooler has been remodeled with newer over installed ACM-Free sheetrock, carpeting & suspended ceiling system. The underlying cork & tar layers were proven ACM-Free. There is approximately 1,450 ft² of this material present with both rooms. Represented by bulk samples 14-037.1-99, 100 & 101.

March 25, 2014 S-2 Mountain Consulting Services, LLC

White Non-Pliable Caulking Sealant located present between the wood doorframes to exterior concrete wall joints of the exterior entry door units of the building was found to contain asbestos. This class II, non-friable, miscellaneous material contains 1-2% chrysotile asbestos. There is approximatly 440 linear feet (lf) of this material present with 24 exterior entry door units. Represented by Bulk Samples 14-037.1-129, 130 & 131.

MATERIALS ASSUMED TO BE REGULATED FOR ASBESTOS

The following homogeneous materials present with the facility are being assumed to contain asbestos based on inspector expertise, age of construction, material type and/or inaccessible suspect material (Regulated ACM):

Boiler Segments Sealant associated with enclosed cast iron segments of the 2 small boilers present within the basement mechanical rooms of the north & south wings of the building is ASSUMED to contain asbestos. This material is a class I, friable, thermal systems insulation (TSI) type. If present, there should be approximately 224 lf of material within the boilers.

Vermiculite Attic Insulation located under ACM-Free rot wool type blown-in insulation throughout the attic crawl space of the building was found to contain TRACE amounts of actinolite asbestos. There is approximately 13,000 ft² of this material present ranging in depths from 1” to 3” inches. This material has a history of producing false negative results by polarize light microscopy (PLM) and causing environment and health hazards when disturbed.

Although this material is not regulated for asbestos content by MDEQ, it should not be considered a safe material and it is recommended that this material be handled as a regulated Asbestos Containing Material. Represented by Bulk Samples 135, 136 & 137.

SUSPECT MATERIALS PRESENT BUT NOT TESTED

The following suspect building materials present with the structure were intentionally not tested for asbestos content at this time, due to either water damage intrusion potentials or warrantee voiding situations. These materials must be tested for asbestos content prior to any future impacting for renovation or demolition:

Black Membrane Roofing System (present w/flat roof decks) Red Ceramic Tile Roofing

MATERIALS PROVEN TO BE ASBESTOS-FREE

No other suspect building materials associated with the structure were identified to be tested for asbestos content during this survey. The building owner or tenant is responsible, under OSHA regulations, to notify all maintenance and custodial workers of the presence and location of ACM.

Asbestos containing materials must be handled and disposed of in accordance with OSHA, NESHAP, and local regulations.

LEAD COATINGS SURVEY SUMMARY

Mountain Consulting used a “Dynasil, RMD, LPA-1” X-ray fluorescence (XRF) lead spectrum analyzer, Serial Number 3627, for nondestructive sampling for suspect lead based paints and lead glazed ceramic tile materials present throughout the building for this project. Mountain Consulting collected a total of Three-Hundred-&-Forty-Five (345) XRF suspect lead coating assays & calibration readings for this project.

Any paint films or ceramic tile glazing’s with lead concentrations of 1.0 mg/cm² (milligrams per square centimeter) or greater were classified as Regulated Lead Containing Materials. In addition, the substrate condition was visually assessed at each assay test site. Any paint or glaze coatings that produced results below the 1.0 mg/cm² threshold were bulk sampled using destructive methods to verify the actual lead content in parts per million (ppm).

The paint or ceramic tile glaze coatings associated with the following components are considered to be regulated lead containing materials by XRF Assay testing. These materials are potential lead hazards, contractors working on or around these materials should be informed of the lead content and potential lead hazard:

Any coating that contain lead concentrations greater than 100 parts per million (ppm); proven to be LBP by XRF Assay Testing; or, assumed to be a lead coating associated with this project are regulated by Federal and/or Montana State regulations.

Explanations of regulations are detailed as follows:

The Occupational Safety and Health Administration (OSHA) 29 CFR 1926.62 lead in construction standard does not define a definition for lead based coatings or materials, but does establish safe airborne exposure limits for employees working with lead containing materials, by permissible exposure limit (PEL). So in summation; if any material or coating contains lead above 100 ppm then abatement, renovation or demolition contractors must demonstrate worker health and safety due diligence.

This includes lead awareness training for all affected employees, establishment of proper employee personnel protective equipment (PPE), proper demarcation of effected work area(s), and performance of negative exposure assessment (NEA) lead air monitoring prior to downgrading any established PPE.

The Federal Dangerous Waste Regulation (40 CFR Part 261) requires that lead containing materials with a lead content above 5,000 ppm threshold be treated as lead hazardous waste, until toxic characterization leeching procedure (TCLP) bulk waste stream sampling prove otherwise. The TCLP lead characterization threshold is 5 ppm. TCLP lead waste stream bulk sampling and analysis was not conducted as part of this survey project.

GOOD-FAITH ACM SURVEY

GOOD-FAITH ASBESTOS MATERIALS & LEAD COATINGS SURVEY; HISTORIC

BUILDING #26; FORT MISSOULA FACILITY; MISSOULA, MONTANA

ASBESTOS CONTAINING MATERIALS SURVEY REPORT

1.0 INTRODUCTION

The USDA Forest Service of Missoula, Montana, contracted Mountain Consulting Services, LLC (Mountain Consulting) to provide a good-faith asbestos materials survey for the suspect building materials present with the 3-story; 39,000 ft²; Historic Building 26 located on the Fort Missoula facility addressed at 322 Fort Missoula in Missoula, Montana.

This project was conducted to facilitate new occupancy phased renovations for the Building 26 structure. No prior survey documentation was provided for this project.

The field survey activities for this project were conducted on March 5th & 6th of 2014 by Mr. Samuel W. Bailey Jr., EPA Accredited AHERA Building Inspector; Certification: BIR-13-038/MTA-3565;

Expiration: October 8, 2014. (See Appendix A for inspector and laboratory certifications.)

2.0 SCOPE OF WORK

The scope of work was designed to meet the requirements for asbestos inspection and due diligence notification in the Occupational Safety and Health Administration (OSHA) Asbestos Standard (29 CFR 1926.1101); the National Emission Standards for Hazardous Air Pollutants (NESHAP 40 CFR 61); applicable portions of the Asbestos Hazardous Emergency Response Act (AHERA) & regulations in 40 CFR 763; and, the Administrative Rules of Montana, Title 17, Chapter 74, Subchapter 3, governed by the Montana Department of Environmental Quality (MDEQ).

The survey was conducted through visual evaluation, classification and analysis of suspected asbestos-containing materials (ACMs) used in the construction or remodeling of the surveyed building. The survey included the following tasks:

Visual survey and assessment of the location and condition of suspected materials.

Collection and analysis of bulk samples from suspected asbestos containing materials.

Preparation of a report summarizing the identification and assessment of any asbestos containing materials and material found not to contain asbestos.

3.0 ASSESSMENT SURVEY PARAMETERS

3.1 HOMOGENEOUS AREAS

Homogeneous materials are those considered to be consistent throughout an area based on color, texture, and construction era. For the purpose of this survey, homogeneous areas were delineated using the construction era, material composition, and material location as the primary considerations.

Material appearance, texture, size, color, and analytical results may support assumptions about each material’s homogeneity.

3.2 BULK SAMPLING

Suspected ACMs were collected according to guidelines in 40 CFR 763.85 and were sampled to determine the type and percentage of asbestos by volume. At least three (3) samples were collected from each selected miscellaneous and thermal system insulation materials. Suspect surfacing materials were sampled according to the AHERA “3/5/7 rule.”

For other types of suspect materials, or materials assumed to be non-ACM, regulations require the on-site AHERA building inspector to determine the appropriate number of samples. The quantity of material present, manufacturer’s labels, appearance, construction or renovation era, and inspector’s expertise were used to determine the number of samples. A homogeneous material is considered to be an ACM if one or more sample results are equal to or greater than 1% asbestos.

The EPA recommends that at least three samples be analyzed by polarized-light microscopy (PLM) for the following types of materials in order to prevent false negative results (less than 1% asbestos):

Materials that contain low concentrations of asbestos fibers (less than 10%);

Materials with asbestos fibers tightly bound in a matrix;

Materials with milled asbestos fibers (fine fibers);

Materials with hand-mixed asbestos fibers; and Materials with a combination of these characteristics.

All bulk samples must have results below 1% asbestos before the material may be classified in accordance with AHERA rules as not being an ACM. However, if asbestos is detected in the material at less than 1%, OSHA worker health and safety due diligence regulations may still apply.

3.3 LABORATORY AND ANALYTICAL METHODS

Mountain Consulting performed destructive bulk materials testing of suspect building materials to verify the presence of asbestos minerals or prove asbestos-free content. Mountain Consulting collected 165 bulk material samples from 52 different homogeneous suspect building materials or material systems identified during survey activities. Laboratory analysts sub-divided 15 submitted samples, and did not analyzed 2 submitted samples, resulting in a total of 178 samples analyzed for this project.

March 25, 2014 ACM - Page 2 Mountain Consulting Services, LLC

All samples were submitted for analysis to Mountain Laboratories of Spokane, Washington using chain of custody procedures. Mountain Laboratories participates in the national voluntary laboratory accreditation program (NAVLAP) and is a NAVLAP accredited asbestos testing laboratory, NAVLAP code: 101890-0. All samples were analyzed to determine asbestos type and content using PLM with dispersion staining in accordance with the following methods:

EPA EPA 600/R-93/116, “Method for the Determination of Asbestos in Bulk Building Materials” (July 1993).

EPA “Interim Method for the Determination of Asbestos in Bulk Insulation Samples” (40 CFR Part 763, Subpart F, Appendix A; May 27, 1982).

ASTM Draft “Standard Method of Testing for Asbestos Containing Materials by Polarized Light Microscopy” (ASTM Committee D22.05; January 14, 1988).

4.0 RESULTS

This section describes suspect materials that were proven to be asbestos containing (Regulated ACM) or proven to be free of asbestos minerals (ACM-Free). (Refer to the bulk sample analysis report in Appendix B for specific sample composition and Appendix C for sample location drawings).

4.1 REGULATED ASBESTOS CONTAINING MATERIALS

ACMs are materials proven to contain at least 1% asbestos or greater. AHERA (asbestos hazards emergency response act) and NESHAP (national emissions standard for hazardous air pollutants) regulations distinguish between friable and non-friable forms of ACM. A friable material is defined as one that can be “crumbled, pulverized, or reduced to powder by hand pressure when dry.” Friability is an indication of a material’s ability to release asbestos fibers into the air.

Regulated ACMs are defined by NESHAP as all friable ACM and non-friable ACM that may be disturbed by renovation or demolition.

The following homogeneous building materials were found to contain greater than one percent (>1%) asbestos content by laboratory analysis and are considered to be (Regulated ACM) requiring proper abatement prior to being impacted by renovation or demolition activities:

9”x 9” Vinyl Floor Tiling (VFT) (Green & Black in Colors-Checkered Pattern) located throughout the majority of the 1st and 2nd floors of the building either exposed, hidden under carpeting, hidden under vinyl sheet flooring (VSF), hidden under newer VFT or VSF & wood sub-flooring systems was found to contain asbestos. The class II, non-friable, miscellaneous materials contain 4-6% chrysotile asbestos. The total quantity of material present is 22,600 ft².

The quantities break for overlaid material types is as follow: There is approximately 1,360 ft² of this material exposed (1st floor NE office and the 2nd floor NE dormitory); approximately

March 25, 2014 ACM - Page 3 Mountain Consulting Services, LLC

5,780 ft² of this material present hidden under ACM-Free vinyl sheet flooring (VSF) (1st & 2nd floors; N & W wings); approximately 9,800 ft² of this material present hidden under carpeting (1st floor N, W & S wings; 2nd floor N & W wings); and, approximately 5,660 ft² of this material present hidden under ACM-Free VFT or VSF and wood sub-flooring (1st floor S wing hallway & 2nd floor entire S wing). It should be noted that the associated black flooring mastic material was proven to be ACM-free. Represented by bulk samples 14-037.1-72, 73 & 74.

Exposed Silver Painted Tar Coating Layers associated with the built-up tar adhered corkboard wall paneling system present within the old cooler rooms of the northeast and southeast center end rooms of the 1st floor within the building was found to contain asbestos.

The class II, non-friable, miscellaneous coatings material contains 7-10% chrysotile asbestos. It should be noted that this material is present with the walls, ceilings and assumed to be present under the elevated concrete floors within each room. Also the interior of southeast wing cooler has been remodeled with newer over installed ACM-Free sheetrock, carpeting & suspended ceiling system. The underlying cork & tar layers were proven ACM-Free. There is approximately 1,450 ft² of this material present with both rooms. Represented by bulk samples 14-037.1-99, 100 & 101.

White Non-Pliable Caulking Sealant located present between the wood doorframes to exterior concrete wall joints of the exterior entry door units of the building was found to contain asbestos. This class II, non-friable, miscellaneous material contains 1-2% chrysotile asbestos. There is approximatly 440 linear feet (lf) of this material present with 24 exterior entry door units. Represented by Bulk Samples 14-037.1-129, 130 & 131.

4.2 MATERIALS ASSUMED TO BE REGULATED ACM

The following homogeneous materials present with the facility are being assumed to contain asbestos based on inspector expertise, age of construction, material type and/or inaccessible suspect material (Regulated ACM):

Boiler Segments Sealant associated with enclosed cast iron segments of the 2 small boilers present within the basement mechanical rooms of the north & south wings of the building is ASSUMED to contain asbestos. This material is a class I, friable, thermal systems insulation (TSI) type. If present, there should be approximately 224 lf of material within the boilers.

Vermiculite Attic Insulation located under ACM-Free rot wool type blown-in insulation throughout the attic crawl space of the building was found to contain TRACE amounts of actinolite asbestos. There is approximately 13,000 ft² of this material present ranging in depths from 1” to 3” inches. This material has a history of producing false negative results by polarize light microscopy (PLM) and causing environment and health hazards when disturbed.

Although this material is not regulated for asbestos content by MDEQ, it should not be considered a safe material and it is recommended that this material be handled as a regulated Asbestos Containing Material. Represented by Bulk Samples 135, 136 & 137.

March 25, 2014 ACM - Page 4 Mountain Consulting Services, LLC

4.3 SUSPECT MATERIALS PRESENT BUT NOT TESTED

The following suspect building materials present with the structure were intentionally not tested for asbestos content at this time, due to either water damage intrusion potentials or warrantee voiding situations. These materials must be tested for asbestos content prior to any future impacting for renovation or demolition:

Black Membrane Roofing System (present w/flat roof decks) Red Ceramic Tile Roofing
