1. INTRODUCTION

Veterans Affairs, Medical Center, Grand Junction, Colorado, (VAMC Grand Junction) requested

Planate Management Group (Planate) conduct an asbestos containing materials (ACM) survey to identify any potential ACM and locations within the facility buildings.

This report provides the results of the sampling and analysis of ACM at all the buildings at

VAMC Grand Junction in February and September 2021. The purpose of the assessment was to evaluate the presence and extent of ACM throughout the facility.

Field activities conducted for this investigation included the collection of 1,517 ACM samples from VAMC Grand Junction.

2. PURPOSE & LIMITATION

The purpose of this ACM sampling was to provide an understanding of the degree of potential contamination that is on-site and will need to be addressed before any repair or renovation work is initiated. The findings from this testing will give VAMC Grand Junction the foundation needed to identify and recommend the abatement strategy in the event of any operational activities intruding on these material locations.

Planate’s approach was to identify the presence and extent of all previously identified ACM locations and to identify any other ACM locations not previously documented. The data collected was thoroughly analyzed, and locations marked on drawings, to allow an easy pathway for VA personnel to reference the data collected when the information is needed to properly scope future planning and facility renovation activities. The marked-up drawings displaying the raw sampling data are provided as separate attachments.

3. BACKGROUND

The Environmental and Disposal Liabilities (EDL) survey was conducted during May -

September 2019 to develop VAMC Grand Junction’s EDL report. During the EDL survey it was noted that the VAMC Grand Junction was built around 1948 and operational records for that period of time are not available. Based on the site visit in September 2019, there was no visible indication that any environmental contamination existed due to past operations. VAMC Grand

Junction has operated as a hospital since that time. The EDL report identified previously reports that indicated ACM present in buildings 1, 6, 8, 9, 12, and the abandoned steam lines. This ACM survey includes the 20 buildings shown on Figure 1.

4. SITE SAMPLING AND ANALYSIS

During February 2021, Planate collected 755 ACM samples from 19 buildings at select locations across Grand Junction VAMC. During September 2021, Planate collected 762 ACM samples from 8 buildings at select locations across Grand Junction VAMC. The samples were obtained to represent materials that could have ACM present throughout the facility.

5. LABORATORY ANALYTICAL RESULTS

A total of 1,517 building material samples from 20 buildings were collected. Of those samples, 68 came back with positive test results containing either the Chrysotile or Amosite forms of asbestos, or both. The concentration within samples containing asbestos ranged from as low as

<1% up to 30%.

Appendix A provides the listing of all samples collected, their location, and the results of their analysis. The rows that are highlighted in red are the positive samples and the rows that are highlighted in yellow were considered suspect in the first phase of sampling and were resampled or additional samples were taken of the materials that were in question. They were considered suspect when there was a mix of results occurring on the same material or when the result was not consistent with the expected result. The data shown in Appendix A is consistent with the data provided in the laboratory results (Appendix D) and the drawings provided in Appendix C.

Figure 2 details the number of samples containing ACM by building and room.

As shown in Figure 2 and Appendix B, the sampling found the materials to contain asbestos include vinyl floor tile, Terrazzo, transite, drywall taping compound, caulking, window glaze putty, plaster, block steam pipe insulation, floor tile patch material, and insulation pin mastic.

Note that the yellow highlighted samples often came back as having no detected ACM, while similar samples did have ACM detected. This can be caused by inconsistent mixtures in the sampled materials or by different batches of the same materials. Depending on the way remediation is performed, it might be more cost effective to consider these locations as ACM for safety and cost effectiveness.

Some samples were split at the laboratory as a quality assurance measure and show in the laboratory data results as A and B samples. The results were consistent across all of the split samples.

6. RISK ASSESSMENT AND REMEDIAL ALTERNATIVES

6.1 Risk Assessment

Risk assessment is based on a source of potential risk (such as environmental contamination), a route of transport (such as inhalation or ingestion), and a receptor population (facility workers, resident populations, adults, children, etc.). All three elements are needed for a liability to exist and require remedial action.

This project did not include the data collection necessary to perform an in-depth risk assessment since future projects and facility planning needs change over time. It provides information on the potential liabilities from the source of environmental contamination and can be used to derive risk based on anticipated populations being exposed via specific routes of transport.

Based on the sample results, the only potential risk is from direct exposure to the asbestos containing materials that are currently contained within the facility. The only likely way that this will occur is during emergency maintenance situations (i.e., water leak) or during renovation construction.

6.2 Remedial Alternatives

There are always multiple approaches to remedial alternatives and the most cost-effective approach is one that is based on the most specific information on future use of the problem areas and the most effective method for eliminating a potential route of exposure to a potential receptor population. When the least information, is known about future use of problem areas, the most effective method may be to remove the entire source of contamination. But that is likely to be the most expensive approach. If receptor populations can be isolated from the problem areas, then no action could be a viable option. The middle ground in terms of remedial action is to create a barrier to a route of transport by containing or eliminating the potential for exposure.

All of these approaches are site-specific, and costs can be impacted by geographic proximity and construction methods.

In this case, where detailed sampling data is being collected on the location of asbestos containing materials, a reasonable approach would be to incorporate the results of this sampling program into the standard operational procedures for facilities personnel and renovation planning staff. This would allow for proper safety protocols to be in place for staff responding to an operational problem like a water leak or for proper planning for a disturbance of a location containing ACM.

7. CONCLUSIONS AND RECOMMENDATIONS

7.1 Conclusions:

Based on the results of the ACM sampling program, there are potentially 10 materials that are asbestos containing. These include:

• Vinyl Floor Tile

• Terrazzo

• Transite

• Drywall Taping Compound

• Caulking

• Window Glaze Putty

• Plaster

• Block Steam Pipe Insulation

• Floor Tile Patch Material

• Insulation Pin Mastic

All potential materials were sampled and 68 out of 1,517 samples were found to be asbestos containing materials. This report provides the results of a comprehensive survey that documents the materials that were sampled and the materials or locations that were not sampled due to limitations in available access or potential damage to the materials in question (Appendix A, “Negative Space” Tab).

7.2 Recommendations:

This is the final integrated report that includes the data from the phase 1 and phase 2 reports.

The recommendations may differ from the previous reports based on the final analysis of the total data set and should be the most relevant for future action decisions.

• Incorporate the results of this sampling program into the operational standard operational procedures for facilities personnel and renovation planning staff. This would allow for proper safety protocols to be in place for staff responding to an operational problem like a water leak or for proper planning for a disturbance of an location containing ACM.

• Another approach to this would be a stand-alone Asbestos Containing Material

Management Plan that would address the procedures necessary for each potential exposure scenario for each specific material.
