1.0 EXECUTIVE SUMMARY

VW International, Inc. (VWI), contracted with CTA Construction & Environmental, LLC (CTA), to complete a limited, Pre-Demolition Asbestos Assessment of the Bioenvironmental Engineering

Facility (Building 1702) located at 7300 N. Perimeter Road, Malmstrom Air Force Base, MT, 59402. The assessment was completed in accordance with VWI’s Purchase Order No. 6458-

12B-3021, Work Order Number 1301031 and associated CTA Work Order GF13076, dated

September 4, 2013.

A total of 24 separate homogeneous areas (HAs) of building materials were identified and sampled as being suspect asbestos-containing materials (ACM) during the assessment. None of the aforementioned HAs were lab-determined to contain asbestos; therefore, these materials have all been lab-determined to be non-ACM.

4.0 REGULATORY CONSIDERATIONS

The Montana Department of Environmental Quality (DEQ) defines ACM as material containing more than 1% asbestos based on laboratory analysis of the material using the EPA Method

600/R-93/116 (“Method for the Determination of Asbestos in Bulk Building Materials”) by

Polarized Light Microscopy (PLM). Three categories of ACM have been defined in the National

Emissions Standards for Hazardous Air Pollutants (NESHAP) standard, which is established in

Title 40, Part 61, of the Code of Federal Regulations (40 CFR 61.141) and adopted by the DEQ in Title 17, Chapter 74, Subchapter 3, of the Administrative Rules of Montana (ARM 17.74.351).

The NESHAP category definitions are as follows:

� Category I Non-friable ACM mean asbestos-containing packings, gaskets, resilient floor coverings, and asphalt roofing products containing more than one (1) percent (%) asbestos as determined using the method specified in appendix E, subpart E, 40 CFR

763, section 1 (PLM).

� Category II Non-friable ACM means any material, excluding Category I Non-friable

ACM, containing more than 1% asbestos as determined using the method specified in appendix E, subpart E, 40 CFR 763, section 1, PLM that, when dry, cannot be crumbled, pulverized or reduced to powder by hand pressure.

� Regulated ACM (RACM) means a) friable asbestos material; b) Category I Non-friable

ACM that has become friable; c) Category I Non-friable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading; or d) Category II non-friable ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder by the forces expected to act on the material in the course of demolition or renovation operations regulated by the subpart.

The definition of RACM includes all ACM associated with a structure or space which will be impacted by renovation and/or demolition activities. In other words, even non-friable

Category I and Category II ACM may become RACM if disturbed during demolition or renovation activities.

An “asbestos project,” as defined by Montana Code Annotated (MCA) 75-2-502, means the encapsulation, enclosure, removal, repair, renovation, placement in new construction, demolition of asbestos in a building or other structure, or the transportation or disposal of asbestos-containing waste. The term does not include a project that involves less than 3 square feet in surface area or 3 linear feet of pipe. Based on DEQ correspondence and CTA’s understanding of DEQ’s interpretation of the MCA, the removal, transport, and/or disposal of

RACM (or ACM which may become friable) in amounts exceeding this threshold value constitutes an “asbestos project.”

Prior to undertaking a renovation or demolition project, DEQ requires an asbestos inspection to be performed for the structure or portion of the structure to be included in the renovation or demolition project, in accordance with ARM 17.74.354. The inspection must be completed by a

Montana-accredited Asbestos Inspector. Following completion of the inspection, DEQ’s notification requirements should be considered, as follows:

CTA Construction & Environmental, LLC 5

� Project Permit Application – This application should be used for a renovation project where quantities of RACM exceeding the “asbestos project” threshold will be or are likely to be dislodged, disturbed, or impacted (or where any non-friable ACM may be made friable). The application must be submitted to the DEQ at least 10 working days prior to initiation of any activities which will dislodge, disturb, or impact RACM (and/or make friable any ACM), including all transport and disposal activities.

� Demolition Notification – This notification must be submitted to the DEQ prior to demolition of a structure in which no ACM was identified by the inspection.

� Project Permit Application & Demolition Notification – This application & notification should be used where an asbestos project and subsequent demolition will be completed, as described above. The application & notification must be submitted to the DEQ at least 10 working days prior to initiation of any activities which will dislodge, disturb, or impact RACM (and/or make friable any ACM), including all transport and disposal activities.

Asbestos projects must be performed by individuals holding current accreditation as Montana

Asbestos Contractor/Supervisors and/or Asbestos Workers, as stipulated under ARM

17.74.362. Asbestos projects are not considered complete until they have been “cleared” in accordance with the requirements set forth in ARM 17.74.357. It is important to note that clearance monitoring must be completed by a party not contractually associated with the asbestos project contractor, and there may not be any common ownership or employment relationship between the person or entity carrying out the asbestos project and the person or entity conducting the final clearance monitoring or sample analyses.

Demolition projects which will include in-place demolition of non-friable ACM (i.e. non-friable

ACM which will not be rendered friable during demolition activities) require the full-time, on-site oversight of an individual holding a current Montana Asbestos Contractor/Supervisor accreditation to ensure any ACM remaining in the structure is not rendered friable during demolition activities. Friable ACM waste (RACM) must be disposed at a Montana-licensed, Class II landfill. Non-friable ACM waste (Category I or Category II ACM) may be disposed at a

Montana-licensed, Class IV landfill. It is important to note, however, that some landfills will not accept asbestos waste, even if it is non-friable. Arrangements should be made with the landfill prior to initiation of abatement and/or demolition activities.

Handling of RACM, ACM, and non-ACM materials which contain detectable asbestos is regulated by the Occupational Safety and Health Administration (OSHA), as stipulated in 29

CFR 1926.1101. At all times, such materials must be handled in generally the same fashion as

RACM unless a negative exposure assessment is completed to document workers will not be exposed to airborne fiber concentrations in exceedance of the OSHA permissible exposure limit

(PEL) of 0.1 fibers per cubic centimeter (f/cc) as an eight-hour time-weighted average (8-hour

TWA) and the 30-minute, short term excursion limit (STEL) of 1.0 f/cc.

5.0 METHODS

This assessment, including accessible portions of the exterior and interior, was completed in general accordance with the requirements of the Montana DEQ Asbestos Control Program as established in ARM 17.74.354. In addition to complying with the regulations cited above, CTA’s sampling methods generally conformed to the requirements set forth in the Asbestos Hazard

Emergency Response Act (AHERA) as outlined in 40 CFR 763.86; the AHERA sampling methods are generally accepted as the industry standard for asbestos inspections. CTA’s asbestos inspection was performed by a member of our industrial hygiene staff holding current

DEQ accreditation as asbestos inspector. Observations and sample locations were recorded on field forms. Documentation of our inspector’s DEQ accreditations is presented as Appendix A, and sample locations for suspect ACM are presented as Figure 1 in Appendix B.

Bulk samples of suspect ACM were placed in pre-labeled zip-top bags and shipped to SanAir

Technologies Laboratory, Inc. (SanAir), in Powhatan, Virginia, using chain-of-custody protocol.

CTA requested that SanAir analyze the samples using the EPA Method 600/R-93/116 by polarized light microscopy (PLM), which has an analytical sensitivity of 1% asbestos by visual estimate. Where appropriate, CTA also requested that samples found to contain asbestos in concentrations less than 1% be analyzed using the 400 Point Count stipulation of the EPA PLM method to achieve an analytical sensitivity of 0.25%. All samples were analyzed using positive stop analysis. SanAir 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 DEQ.

6.0 RESULTS

A total of 24 separate HAs of building materials were identified and sampled as being suspect -

ACM during the assessment. None of the aforementioned HAs were lab-determined to contain asbestos; therefore, these materials have all been classified as non-ACM.

A complete summary of all HAs of suspect ACM is presented in Table 1 of Appendix C. The summary tables includes descriptive locations of where each material sampled and additional locations where each was observed. The laboratory analytical reports are presented as

Appendix D.

CTA Construction & Environmental, LLC 8

7.0 RECOMMENDATIONS

Based on the aforementioned findings, and with consideration to the applicable regulations described herein, CTA presents the following recommendations.

CTA recommends that VWI proceed with their future-planned demolition of the site building without any special considerations for asbestos.

CTA further recommends that if additional (i.e materials not identified in this report) suspect materials are encountered (or are likely to be encountered) during future renovation and/or demolition activities, they should be sampled and analyzed to determine whether they are ACM, prior to being impacted by those activities.

Material locations are based on arbitrary room designations assigned in the field by CTA for this assessment. When present, numbers in parentheses indicate the number of items identified in a given room; and fractions indicate an approximate portion of the respective room which contains the material.

The percentage of asbestos is reported based on PLM analysis using the EPA Method 600/R-93/116, with a limit of detection (LOD) of 1% by volume.

The In-Place Condition for each material was determined in the field by CTA's Montana-Accredited Asbestos Inspector(s). Materials are classified as either "F" for

"friable" or "NF" for "non-friable" based on their in-place condition at the time of the assessment , in accordance with the Montana Department of Environmental

Quality (DEQ) definitions for the respective terms.

The Anticipated Abatement Condition is based on the National Emissions Standards for Hazardous Air Pollutants (NESHAP) definitions for Category I (non-friable), Category II (non-friable), and Regulated Asbestos-Containing Material (RACM; friable), which have been adopted by the DEQ. For the purpose of this report, the

Anticipated Abatement Condition represents the anticipated condition of the material during removal . These determinations have been made by CTA based on the in-place condition and the professional experience and judgment of CTA's industrial hygienists. Materials assumed to contain greater than one percent (1%) asbestos may be referred to as Presumed Asbestos-Containing Material (PACM). Materials determined to contain less than 1% asbestos are non-asbestos-containing materials (Non-ACM) unless noted otherwise.

The final report cannot be reproduced, except in full, without written authorization from SanAir.

Fibers smaller than 5 microns cannot be seen with this method due to scope limitations. The accuracy of the results is dependent upon the client’s sampling procedure and information provided to the laboratory by the client. SanAir assumes no responsibility for the sampling procedure and will provide evaluation reports based solely on the sample and information provided by the client. This report may not be used by the client to claim product endorsement by NVLAP or any other agency of the U.S. government.

For NY state samples, method EPA 600/M4-82-020 is performed.

Polarized- light microscopy is not consistently reliable in detecting asbestos in floor covering and similar non-friable organically bound materials. Quantitative transmission electron microscopy is currently the only method that can be used to determine if this material can be considered or treated as non-asbestos containing.
