Subject: Limited PCB Sealant Survey

Building 1103 Hanscom Air Force Base Bedford, Massachusetts Cardno ATC Project No. 060.75143.0015

Dear Mr. Rice:

Cardno ATC has been retained by Dewberry to perform a limited survey of polychlorinated biphenyls (PCBs) in suspect sealant materials at Building 1103 located at the Hanscom Air Force Base in Bedford, Massachusetts (the “Site”). The survey was conducted in association with the proposed demolition of the building. The survey was performed on November 8, 2012, by Mr.

Chris Amorelli, Cardno ATC Environmental Scientist.

The survey objective was to evaluate for the presence of PCB-containing sealants (i.e. various caulking and glazing compound materials) that would require special management as part of the proposed demolition. This survey only evaluated sealants that were observed on the date of the survey. The survey did not include testing of other surrounding building materials (i.e. masonry surrounds, frames, sills, etc.) adjacent to the sealants.

Following is a summary of the survey field activities, analytical data, and conclusions.

Field Activities

Cardno ATC collected bulk samples of a total of eight (8) suspect sealant materials throughout the building. Duplicate samples of select homogenous materials were collected but at slightly different locations.

Samples were collected via hand tools (i.e. screwdriver, hammer, pliers, chisel, etc.) and the hand tools were decontaminated with hexane between samples. The samples were then transported under chain-of-custody to Con-Test Analytical Laboratory, Inc. (Con-Test) of East Longmeadow, Massachusetts, for PCB analysis. Samples were analyzed following United States Environmental Protection Agency (USEPA) Method 3540C for Soxhlet extraction and Method 8082 for PCB analysis.

PCB concentrations shown in parts per million (ppm) ND = Not detected above the indicated laboratory detection limit Bold = PCBs detected in sample LF = Linear feet *Estimated quantities only provided for material which were determined to contain PCBs and/or asbestos **Asbestos was not detected in any of the materials analyzed for PCBs

PCBs were detected in four (4) of the eight (8) materials sampled. Two (2) duplicate samples were subsequently submitted to confirm the PCB concentrations of the original samples. Although PCBs were not detected in one of the duplicate samples, based on the detection of PCBs in the original sample the material is considered to contain PCBs. Total PCB concentrations ranged from 0.79 to 1.5 parts per million (ppm). PCBs were not detected in the remaining four (4) materials. Aroclor 1248 was the only Aroclor observed in most of the samples, while Aroclor 1254 was observed in one sample. As reported in the laboratory analytical report case narrative summary, all reported results were within laboratory quality control objectives. The laboratory analytical data is further presented in Table 2 and the associated laboratory analytical report is attached.

Conclusions and Recommendations

Based on the findings of the limited survey, PCB concentrations ranging from 0.79 to 1.5 ppm were observed in four (4) separate sealant materials. The low PCB concentrations indicate that adjacent materials (e.g. metal frames, glass, concrete, etc.) are unlikely to be adversely impacted.

The management of PCB-containing materials is regulated by the Toxic Substances Control Act (TSCA) and associated 40 CFR 761 Regulations, as administered by the United States Environmental Protection Agency

(EPA).

The PCB-containing sealants at the Site are classified under TSCA as Excluded PCB Products, which are materials with concentrations between 1 ppm and 50 ppm and which meet the following additional conditions:

• The products or source of the products containing less than 50 ppm concentration PCBs were legally manufactured, processed, distributed in commerce, or used before October 1, 1984;

Page 2 www.CardnoATC.com

• The products or source of the products containing less than 50 ppm concentrations PCBs were legally manufactured, processed, distributed in commerce, or used, i.e., pursuant to authority granted by EPA regulation, by exemption petition, by settlement agreement, or pursuant to other Agency-approved programs; and

• The resulting PCB concentration (i.e. below 50 ppm) is not a result of dilution, or leaks and spills of PCBs in concentrations greater than 50 ppm.

Excluded PCB Products may be managed by any permitted waste management or recycling facility as long as the facility is made aware of the fact that material being sent to them contains PCBs and their permit allows them to accept these types of materials. Many solid waste and recycling facilities cannot accept materials that contain PCBs at 2 ppm or greater. Workers handling Excluded PCB Products must also be made aware that these materials are present.

Materials which were determined to not contain PCBs are not regulated by the Toxic Substances Control Act (TSCA) or state regulations and, if confirmed not to contain asbestos, may be managed as demolition debris.

It should be noted that no sampled sealant materials contained asbestos. Cardno ATC performed a separate evaluation for the presence of asbestos, provided under separate cover.

Cardno ATC recommends incorporating Excluded PCB Product handling and disposal requirements into project Technical Specifications.
