EXECUTIVE SUMMARY

CTA Construction & Environmental, LLC. (CTA), on behalf of Pinyon Environmental, Inc., was retained by General Services Administration (GSA) to perform asbestos re-inspection services at the Missoula Federal Building/Post Office/U.S. Courthouse (GSA Building number MT0017ZZ), located at 200 East Broadway Street in Missoula, MT 59802-4530 (Site).

The building was constructed in 1908 to 1952. The facility inspected is a three-story, steel and concrete structure with a full basement, attic, and stone and brick finishes. It encompasses a total of 144,681 square feet of building space.

The Missoula Federal Building began its existence as a home for the forestry service and postal service. The original portion of the building was completed in 1912. In 1926, a second building was constructed to house a federal court. One year later, these two, three-story structures were connected by a two-story corridor with a greenhouse on its third floor. This connecting structure was wide enough to accommodate additional offices on one side of the first two floor corridors. In 1935, another three-story addition effectively doubled the size of the existing building to accommodate even more office spaces. New mechanical rooms were also added and connected between the building sections via ductwork and a pipe tunnel. In 1952, a one-story addition was built behind the 1927 corridor to provide the post office with additional room.

Extensive renovation activities occurred in 1976 and 1977 to revamp and update the tenant office space.

Because of the extent of this renovation, many of the same building material finishes can be seen throughout the building, regardless of the original construction date.

Typical interior floor finishes include the following: marble; terrazzo; carpet; 9” by 9” or 12” by 12” vinyl floor tiles; vinyl sheet flooring; and, wood. Under all these finishes is a concrete sub floor with a variety of leveling materials. In some areas felt is also present between the concrete and overlying flooring finish. Typical wall finishes consist of the following: concrete; brick; plaster; gypsum wallboard; and, wood paneling. Ceilings are primarily 2’ by 4’, lay-in panels suspended below original plaster ceilings, 1’ by 1’ glued on ceiling tiles, or concrete decking. Janitor closets and store rooms still have the original plaster ceilings in place. Some ceilings have 1’ by 1’ glue on tiles while gypsum wallboard ceilings are present in remodeled areas. Most rooms have either 4” or 6” vinyl base cove finishes though some of the original marble and wood bases are still in place.

The restrooms generally have ceramic tile floor finishes with ceramic tile also extending part way up the plaster or gypsum wallboard walls.

The exterior of the building is finished with granite, limestone and brick. The Post Office and Courthouse roofs have a slight pitch while the 1935 and 1952 additions exhibit flat roofs. The entire roof was refinished in 1993 and is asphalt with a gravel layer finish. Roofing materials were not sampled during this inspection but asbestos-containing materials are assumed to be present under the new roof.

Heat for the building originates from boilers located in the 1935 portion of the building. Perimeter wall heat is provided by radiant or fan coil type units. Heat pumps with fan coils provide forced-air heat to other interior spaces. In 1976, updates to the Heating, Ventilation, and Air Conditioning (HVAC) systems included the installation of many new pre and re-heat coils, heat registers, the evaporative water cooling tower, steam coils, and exhaust air ducts. In 1983, much of the piping was updated, with fiberglass insulation being installed on associated piping’s straight-runs and fittings. In 1992, a boiler replacement project converted the steam heat to hot water heat. At this time, most of the remaining asbestos-containing pipe insulation was removed as the project involved the demolition of the old steam and condensate piping, where accessible. New piping for the heating and chilled water was installed in most cases with no insulation being used. The new boilers were connected to the original breaching, which is assumed to be insulated with asbestos.

February 28, 2014

Though most of the old piping has been removed, the piping in most wall cavities and pipe chases was abandoned in place. There is still original, asbestos-containing pipe insulation located in these areas as well as random locations above suspended ceilings where only portions of the original piping was replaced or re-insulated. In addition, the remaining ends of abandoned cut off steam pipes are still exposed at wall and ceiling penetrations. Some of this, as well as straight-run and fitting insulation observed in the one of the pipe chases, is in poor condition. The original asbestos-containing duct insulation in the 1935 portion of the building is still present in attic spaces off the penthouse. CTA assumes this material is also present in two air shafts in the 1935 construction and on ductwork above third floor plaster ceilings in the 1926 construction. The duct insulation locations and quantities were assumed in these two locations due to limited access.

As discussed in the Executive Summary, there is a substantial quantity of asbestos-containing duct insulation present in the attic of the 1935 construction (38T8.2). CTA visually-verified the presence of this material via two locked access hatches located in Room 401 (Penthouse A). Quantities shown in the room-by-room summary and in the abatement cost estimate were derived from previous similar assessments. While visual inspection confirmed that the material is still present in the 1935 attic space, CTA assumed the material to be present in the two air shafts located in the 1935 building and also in the above ceiling areas of the third floor of the 1926 building.

It is important to note that Northern Industrial Hygiene, Inc. (Northern’s) Asbestos Re-Inspection Report, dated 2007, was utilized in the field to complete this 2014 survey; specifically, reviewing the room-by-room summary in conjunction with the associated floor plan figures to ascertain whether or not Asbestos-Containing Building Materials (ACBM) materials had been removed via abatement activities between 2007 and current. If ACBMs were observed where indicated in the 2007 inspection, their condition(s) and approximate quantities were documented on field forms. The aforementioned Northern report is referenced herein as the 2007 inspection.

Abatement History

This 2014 re-inspection report includes the addition of five (5) materials suspected to contain asbestos that were sampled and laboratory-analyzed; resulting as Non-Asbestos-Containing Materials (Non-ACM). This 2014 re-inspection report also includes a summary of the five (5) reports supplied by the onsite GSA property manager, documenting abatement and/or cleanup of ACBMs and associated debris from the site. Additionally, some of the ACBM(s) outlined in the 2007 inspection are no longer present in all, or any, of the locations detailed in that report. This information is summarized below, to extents feasible.

In 2010, Abatement Contractors of Montana (ACM) were contracted to complete “emergency asbestos abatement project”, along the first floor of the Missoula Federal Building. A full detailed scope for this abatement was not described in the Certificate of Completion, provided by the GSA property manager.

According to the Affinity Environmental (Affinity) Inspection & Area Air Sampling for Asbestos Containing Materials report, dated October 19, 2012, ACM was contracted to complete cleaning of ACBMs and associated debris from the Forest Service Storage Room (Room G62), the IT Computer Room (Room G58), and the Freight Elevator Corridor to accommodate a remodeling project involving a pipe chase. The documentation reports a successful clearance testing event.

According to the Affinity Inspection & Air Clearance for Asbestos Containing Materials report, dated December, 27, 2012, ACM was contracted to complete cleaning of ACBMs (floor tile and other debris) from the Third floor, Room #16 of the Missoula Federal Building. CTA opines that Room #16 is actually referring to a stairwell along the northeast portion of the third floor (Room 318A). The documentation reports a successful clearance testing event.

Asbestos Re-Inspection Report Page 3

February 28, 2014

According to the Affinity Inspection & Air Clearance for Asbestos Containing Materials report, dated February 6, 2013, ACM was contracted to complete removal and/or cleaning of ACBMs (floor tile, mastic and other debris

– 08F3.1) from the Third floor 1910 Section hallway; specifically, the Greenhouse. Based on CTA’s field observations, tile and mastic were not present in Room 329C (Greenhouse) and tiles were removed leaving behind ACBM black mastic only in Rooms 329 and 329B. It should be noted that Room 321 has been removed since the 2007 inspection and CTA combined this former space with the hall section denoted now as Room

329. The documentation reports a successful clearance testing event.

According to the Affinity Inspection & Air Clearance for Asbestos Containing Materials report, dated September 5, 2013, ACM was contracted to complete removal and/or cleaning of ACBMs (TSI elbows, mudded-fittings and associated debris – 35T2.1 and 35T3.3) from the Boiler Room (G18) of the Missoula Federal Building. The documentation reports a successful clearance testing event.

Two (2) ACBMs outlined in the 2007 inspection report were not observed by CTA personnel during the 2014 re-inspection. These materials include the following: beige with gray streaks 9-inch by 9-inch floor tiles and mastic (08F3.3); and, straight-run pipe insulation (27T3.1).

Notes:

“ inches ACM Asbestos Containing Material ND None Detected O&M Operations and Maintenance

Most of the asbestos-containing materials throughout the Missoula Federal Building are intact and in generally good condition overall. For this reason, CTA recommends that a formal operations and maintenance program be developed to assist in maintaining the ACBMs within the building. The program would include provisions for the routine re-inspection of the identified ACBM, appropriate maintenance and cleaning procedures for the

Asbestos Re-Inspection Report Page 6

February 28, 2014 facility and a method for informing in-house and contract workers of the hazards associated with the ACBM, as well as proper work methods and personal protective equipment (PPE) to be utilized, if applicable. The presence of ACBM within the building should be included in the hazard communication information provided to all building occupants and GSA personnel.

There are a few exceptions to the aforementioned recommendations. The asbestos-containing materials in one (1) pipe chase (Room G30B) still show signs of damage and deterioration, although the bottom of the chase has apparently been cleaned of associated ACBM debris. As recommended in the 2007 inspection report, pipe chase access points have been secured with a locking hatch as observed during the 2014 re-inspection.

Damaged materials as observed during the 2014 re-inspection are as follows:

Room G03 Thermal Systems Insulation (TSI) exposed at previous sample points;

Room G17 TSI breeched at seems and displays signs of possible mold growth;

Room G59 Absent jacketing material on mudded-fittings (residual mud only present);

Room 106 Chipped floor tiles;

Room 127 Chipped floor tiles;

Room 208A Jacket delaminating from pipe insulation;

Room 219 Edges of radiator backing exposed;

Room 221 Edges of radiator backing exposed;

Room 222 Edges of radiator backing exposed;

Room 225B Jacket breeched at seem; and, Room 302A Tears in pipe insulation jacket.

1. Introduction and Scope of Work

CTA Construction & Environmental, LLC. (CTA) was retained by Pinyon Environmental who was retained by General Services Administration (GSA) to perform a re-inspection asbestos survey of the Missoula Federal Building/Post Office/U.S. Courthouse (GSA Building number MT0017ZZ), located at 200 East Broadway Street in Missoula, MT 59802-4530. The purpose of this survey was to identify friable and non-friable suspect asbestos-containing building materials (ACBM).

The scope of this inspection included the following activities:

Surveying, identifying, and sampling suspect friable and non-friable ACBM.

Preparing this comprehensive report documenting the sampling procedures and results of the ACBM survey.

To accomplish this survey, all accessible areas of the building were identified by name and assigned room numbers. A summary of identified functional spaces is presented in Table 3-1.

Within each space, suspect building materials were identified. C T A uses a standardized numbering format to identify suspect building materials, and to identify bulk samples.

The report contains six sections. The six sections are: introduction and scope of work; inspection procedures;

survey findings; conclusions and recommendations; removal cost estimate; and limitations sections. The report also contains seven appendices. Appendix A contains figures, Appendix B contains tables, Appendix C contains the laboratory analysis reports and chain of custodies, Appendix D contains a Photographic Log, Appendix E contains abatement and/or clearance report documents, Appendix F contains general inspection information, and Appendix G contains inspector and laboratory certifications.

2. Inspection Procedures

The asbestos survey was performed using the applicable portions of the currently recognized standard protocol developed for schools under AHERA, as promulgated in Title 40, Code of Federal Regulations (40 CFR), Part 763 and as amended in the Federal Register (EPA, 2011). Since the primary concern for this investigation was to identify potential asbestos hazards in the entire building, CTA representatives visually inspected existing conditions within the entire facility. An overview of asbestos and current regulations and a glossary of common terms are presented in Appendix F.

2.1 Inspection and Sampling

The inspection was conducted by our State certified and AHERA accredited asbestos inspector, and consisted of a detailed visual survey of surfacing materials, thermal system insulation, and miscellaneous materials throughout the building. Suspect ACBM was then grouped into homogeneous materials and sampling plans developed. Components of the inspection included:

Identification of homogeneous suspect materials on a room by room basis (Appendices A and B).

An assessment of known or assumed ACBM, generally classifying the materials using categories defined in the AHERA and National Emission Standards of Hazardous Air Pollutants (NESHAP), for asbestos. A description of NESHAP categories is presented in the Section 3 Room-By-Room Table Key.

Homogeneous suspect ACBM’s were, for the purpose of this study, placed into the following four materials type categories: Thermal System Insulation (TSI), surfacing materials, miscellaneous materials, and floor covering. AHERA sampling protocol specifies sampling procedures for each material type (Appendix F).

Sample locations for this survey were chosen in a non-random fashion, with emphasis placed on obtaining samples of each type of accessible, suspect material and minimizing damage to the material being sampled (Appendix A Figures A-1.1, A-1.2, A-1.3, A-1.4, A-1.5, and A-1.6). Samples were collected by carefully removing small portions of the suspect material in a non-abrasive manner. If possible, samples from existing damaged areas or loose pieces of material were collected. Samples were obtained by using techniques such as wet slicing, wet boring or similar methods designed to limit contamination of the area during sampling. The sampled area was sealed using patching compounds, duct tape, or spray encapsulates as appropriate to the material being sampled.

Immediately after collection, samples were placed in pre-labeled plastic containers. Containers with samples were then placed in a large re-sealable plastic bag for transportation to the laboratory.

Documentation of our inspector’s asbestos accreditations is included as Appendix G.

2.2 Laboratory Analysis

Bulk samples obtained during the inspection were assigned bulk sample numbers and entered on sample chain-of-custody forms, followed by being shipped to EMSL Analytical, Inc. (EMSL) in Cinnaminson, New Jersey.

Laboratory analysis was performed in accordance with EPA Method 600/R-93/116, which employs polarized light microscopy (PLM) with dispersion staining for identification of mineral forms of asbestos, and has a limit of detection (LOD) of approximately 1%, by volume. Where appropriate, CTA requested that samples confirmed to contain asbestos in concentrations less than 1%, be analyzed further using the 400 Point Count Stipulation of the EPA PLM method to achieve an analytical sensitivity of 0.25%.

February 28, 2014

EMSL is accredited by the National Institute of Standards and Technology’s (NIST) National Voluntary Laboratory Accreditation Program (NVLAP) for PLM analysis, and therefore meets the proficiency requirements of the Department of Environmental Quality (DEQ). Documentation of EMSL’s laboratory certifications is included as Appendix G.

2.3 Quality Assurance and Quality Control

Quality Assurance and Quality Control (QA/QC) measures adopted by CTA involved both field and office components. Key parameters are summarized below:

Field QA/QC

Review inspection forms for completeness

Check homogeneous materials listing for sufficient number of collected samples

Verify locations of major mechanical components

Office QA/QC

Review lab results for completeness

Ensure appropriate cross-referencing of results, forms for given ACBM

Ensure drawings are updated as necessary following field QC

Verify approximate quantities of ACBM based on drawing review

Review recorded field comments for meaning, incorporate as necessary into report

Some of this, as well as straight-run and fitting insulation observed in the one of the pipe chases, is in poor condition. The original asbestos-containing duct insulation in the 1935 portion of the building is still present in attic spaces off the penthouse. CTA assumes this material is also present in two air shafts in the 1935 construction and on ductwork above third floor plaster ceilings in the 1926 construction. The duct insulation locations and quantities were assumed in these two locations due to limited access.

As discussed in the Executive Summary, there is a substantial quantity of asbestos-containing duct insulation present in the attic of the 1935 construction (38T8.2). CTA visually-verified the presence of this material via two locked access hatches located in Room 401 (Penthouse A). Quantities shown in the room-by-room summary and in the abatement cost estimate were derived from previous similar assessments. While visual inspection confirmed that the material is still present in the 1935 attic space, CTA assumed the material to be present in the two air shafts located in the 1935 building and also in the above ceiling areas of the third floor of the 1926 building.

Table 3-1 summarizes each room/functional space by floor, room number, description, and additional comments as necessary.

3.2 Findings

CTA conducted an asbestos re-inspection at the Missoula Federal Building/Post Office/U.S. Courthouse on January 13-15, 2014. Materials assumed to contain asbestos were not sampled to protect structural integrity.

While the five (5) suspect homogeneous materials, sampled during the 2014 re-inspection, were confirmed not to contain asbestos, the following materials were previously assumed and/or confirmed to contain asbestos:

Table B Key

The following is an explanation of each column listed in Table B:

Floor No.

The floor level of the building.

Room No.

A list of all spaces in numeric order. Due to the need for each inspected space to have a unique identifying number, the room numbers in this column may differ from the actual room numbers used in the building. The drawings in Appendix A are annotated with the assigned numbers from the inspection and can be used to resolve any questions.

Room Description

A general description for the use of the room at the time of the inspection.

Homogeneous Material Number and Description

This column provides a number and description of all suspect ACBM in each functional space/room. A summary of homogeneous ACBM types can be found in Appendix B, Table 1. A list of non-asbestos containing homogeneous materials can be found in Appendix B, Table 2.

Bulk Sample No.

Bulk samples collected during this current inspection are listed in this column. Sample location within the room and sample analysis can be found in Appendix B, Table 3.

ACBM

This column either lists “Yes” for suspect materials determined to be an ACBM or “No” if analysis of the suspect material comes back negative for the presence of asbestos.

Friable

If a suspect material can be reduced to powder with hand pressure, “Yes” will be typed into this column.

Otherwise, “No” will be typed into the column.

ACBM Quantity

The quantity of a specific ACBM located within a room will be listed in this column.

Units

This column lists how the ACBM was measured (SF = square feet; EA = each; LF = linear feet).

February 28, 2014

Hazard Rank and Removal Priority

Per AHERA regulations, each known and/or assumed friable asbestos-containing material is assessed for condition and is assigned a Hazard Rank number and Removal Priority number which are listed in these two columns. The Hazard Rank and Removal Priority for Friable ACBM table is located on the following page as a supplement to Table B and details the procedure for assigning AHERA Hazard Ranking and Removal Priorities for materials based on the degree of damage observed.
