SECTION 1

SL0220171156BOI 1-1

Environmental Inspection On December 14 and 15, 2016, Michael Wirtz performed an environmental inspection on Building 2215 for the presence of asbestos-containing building materials (ACBM), lead-based paint (LBP), and sources of mercury, polychlorinated biphenyls (PCB) and refrigerants. Mr. Wirtz is a trained and certified AHERA Building Inspector and U.S. Environmental Protection Agency- (EPA) certified LBP building inspector (see Appendix A).

In total, five rooms (18, 48, 69, 87 and 90) were not accessible during the time of the inspection (see the figures in Appendix C). No inspections were completed within these rooms. If any new building materials are discovered within these rooms, additional samples may be required. However, based on the continuity of building materials present throughout the building, it is unlikely something different is present.

1.1 Asbestos Building Inspection

During the asbestos inspection, Mr. Wirtz performed a visual inspection of Building 2215 to identify suspect ACBM. The inspection included flooring materials and mastics, wall materials, and insulations (pipe wrap). The inspection did not include inspection of the roof; however, the roofing material is metal sheeting. A total of 36 bulk samples were collected, representing one homogeneous sampling area.

Homogeneous sampling areas are areas containing building materials of similar color, texture, and appearance with a common construction area. The asbestos building inspection was performed in accordance with the Guidance for Controlling Asbestos-Containing Materials in Buildings (EPA, 1985).

The bulk samples collected for the presence of asbestos included flooring materials, glues/mastics, pipe insulation, window caulking, and miscellaneous building materials found within the building.

Bulk samples of suspect ACBM were collected using sampling methods to reduce the risk of dust. Each sample was assigned a unique sample identification number based on the homogeneous sampling material and sample location. The location of each sample was logged onto a facility diagram, and a photograph was taken of each suspect building material (Appendix B). Each sample was placed into a clean plastic bag with the sample identification written on the outside of the bag. A diagram showing the approximate location of each suspect ACBM sample collected is included in Appendix C.

All suspect ACBM samples were sent to TestAmerica Laboratory in Nashville, TN (TestAmerica) for analysis along with a chain-of-custody (COC). TestAmerica is a National Voluntary Laboratory Accreditation Program (NVLAP) accredited asbestos laboratory. Laboratory accreditations are provided in Appendix D. Samples were analyzed using polarized light microscopy (PLM), EPA Method 600/R-93/116.

1.2 Lead-Based Paint Building Inspection

A LBP inspection was conducted on Building 2215 utilizing a modified assessment plan following the U.S. Department of Housing and Urban Development (HUD) Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing (1995 and 1997 Revision). The LBP inspection was limited to the building structure only. Thirty-one (31) physical samples of each homogeneous sampling area were collected. Homogeneous sampling areas are areas containing building materials of similar color, texture, and appearance with a common construction area.

SECTION 1 – ENVIRONMENTAL INSPECTION

1-2 SL0220171156BOI

Bulk samples of suspect LBP were collected with a cutter or other tool, as appropriate. Each paint sample was assigned a unique sample identification number. The location of each paint sample was logged onto a facility diagram, and a photograph was taken of each suspect painted building material (Appendix B). Each paint sample was placed into a clean plastic bag with the sample identification written on the outside of the bag. Facility diagrams showing the approximate location of each suspect paint sample collected are included in Appendix C.

All suspect LBP samples were sent to TestAmerica Laboratory in Nashville, TN (TestAmerica) for analysis along with a chain-of-custody (COC) form. Samples were analyzed using EPA Method SW 846 6010B.

1.3 Mercury, PCBs, and Refrigerants Inspection

During the walk-around of Building 2215, Mr. Wirtz also looked for sources of mercury (thermostats and lighting), PCBs (light ballasts), and refrigerants. Mercury inspections included removing the face plates of thermostats and looking for mercury ampules. In addition, observations were made at fluorescent lights for any indication as to whether they contain mercury. PCBs are routinely found in lighting ballasts;

however, taking apart lights is contractually not allowed. Refrigerants can be found in air-conditioning equipment and refrigerators.

The face plates to random thermostats were removed to expose the inside. None of the thermostats inspected contained a mercury ampule. The face plates were replaced once the inside was inspected.

In total, approximately 1,826 fluorescent light bulbs were counted within Building 2215 (the equipment storage bay had approximately 63 fluorescent lights [6 feet in length] that were not visually inspected because of lack of access). The majority of the fluorescent light bulbs inspected were either manufactured by Phillips or General Electric and were labeled as containing mercury. If a fluorescent light bulb was found and the label did not indicate whether it contained mercury, it was assumed to contain mercury.

An assumption was made that every fluorescent light bulb pair has an associated ballast (approximately 913 ballasts). The majority of the light ballasts include a label from the manufacturer on the face plate stating whether or not the ballast contains PCBs. Any light ballast to be removed in the future should be inspected. If the manufacturer face plate clearly identifies the contents are PCB free, they can be disposed. However, if the manufacturer face plate indicates, or there is no reference to the light ballasts containing PCBs, then the ballasts should be disposed of or recycled as being PCB containing.

There was no indication what chemicals were used within the air-conditioning system for Building 2215.

Two refrigerators were found within Building 2215 (rooms 41 and 88). It is unknown what type of coolant was used in either refrigerator.

Results

2.1 Asbestos

All 36 of the asbestos samples collected were reported as nondetect for the presence of asbestos.

Laboratory results and COCs are included in Appendix E.

2.2 Lead-based Paint

The U.S. Department of Housing and Urban Development has defined LBP as any paint, varnish, shellac, or other coating that contains lead equal to or greater than 1.0 milligram per square centimeter as measured by x-ray fluorescence or laboratory analysis, or 0.5 percent by weight (5,000 milligrams per kilogram [mg/kg]) as measured by laboratory analysis. Laboratory results and COCs are included in Appendix E.

One sample exceeded the 5,000 mg/kg standard. The metal piping used for fire suppression, located in the mechanical room, was painted red (Sample ID 2215-LBP-AD) and lead was detected at 58,900 mg/kg. As a result of poor lighting, it is hard to determine how much piping (total length) is associated with the fire suppression system. The remaining 30 homogeneous materials sampled fell below the regulatory level of 5,000 mg/kg and are not considered to be lead-containing by the EPA.

In the Case Narrative (Section 4) of the laboratory analytical report by TestAmerica in Appendix E, the statement “There was insufficient amount of sample provided by the client” was followed by a listing of 21 samples. Ideally, 0.5 grams to 1 gram of material is required to perform an analysis; however, that is not always an option. As the sample weight goes down (less than 0.5 grams), the Reporting Limit (RL) shown in the Client Sample Results (Section 6) goes up. A sample with at least 0.5 gram of material will have a RL of approximately 1 mg/kg (see sample ID 2215-LBP-J with RL of 1.01 mg/kg). The highest RL listed is from sample ID 2215-LBP-A with a RL of 50 mg/kg. All the RLs shown in the analytical report are well within the regulatory limit of 5,000 mg/kg and therefore have no impact on the results.

2.3 Mercury, PCBs, and Refrigerants

There was no evidence of mercury in thermostats in Building 2215.

All 1,826 of the fluorescent light tubes should be considered to contain mercury unless manufacturer labeling indicates otherwise.

Approximately 913 light ballasts are present within Building 2215. Unless indicated on the manufacturer label, all should be considered to be PCB-containing.

Based on the age of the refrigerators located within Building 2215, it is unlikely any carcinogenic refrigerants are within the cooling systems of the refrigerators.
