1. INTRODUCTION

Credere Associates, LLC (Credere) was retained by AECm (the Client) to conduct a Hazardous

Building Material Survey (HBMS) for Substation 7 and Building 165 at the Portsmouth Naval

Shipyard (PNSY) in the Town of Kittery, York County, Maine (Site). This HBMS was completed in conformance with Credere’s September 6, 2019, proposal for the Site.

1.1 PURPOSE AND STATEMENT OF OBJECTIVES

This section was developed to provide clarity and transparency in communicating and interpreting

HBMS results. The primary purpose of this HBMS is to identify hazardous building materials that may be impacted by future renovations and document their location and quantity.

The following objectives were established to aid in designing the scope of work:

Complete an asbestos-containing materials (ACM) survey to identify ACM that may be impacted by future demolition/renovation

Complete a polychlorinated biphenyl (PCB)-containing building materials survey to assess the need for special handling and disposal of certain demolition/renovation debris

1.2 SITE DESCRIPTION

Substation 7 and Building 165 Site are located in the Controlled Industrial Area (CIA) of the PNSY in Kittery, Maine. Substation 7 is comprised of 2400 square foot gravel area with seven concrete pads and several transformers which supply DC and AC power to submarines under repair.

Substation 7 is currently enclosed by a fence. Building 165 is a brick structure of approximately

450 square feet.

2. SCOPE OF WORK & METHODOLOGY

The following sampling program was developed to investigate hazardous building materials

(HBM) at the Site and meet the objectives identified in Section 1.1.

2.1 ACM SAMPLING

On September 10, 2019, a Credere Maine Certified Asbestos Inspector surveyed the Site for the presence of suspect ACM. A copy of the inspector’s certification is included in Appendix A.

Eight materials of suspect ACM were collected in triplicate (i.e., 24 total ACM samples; CA-

SACM-01[A-C] through CA-SACM-08[A-C]). The sampling was performed in accordance with

Maine Department of Environmental Protection (DEP) Chapter 425: Asbestos Management

Regulations (Chapter 425). Seven of the eight sampled materials were analyzed by EMSL

Analytical, Inc. (EMSL) of South Portland, Maine, using Transmission Electron Microscopy

(TEM) according to the U.S. Environmental Protection Agency (EPA) Method 600/R-93/116b.

One of the materials sampled (CA-SACM-03[A-C]) was not analyzed at the client’s request.

Sample locations are summarized in Table 1 and shown on Figure 1.

2.2 PCB-CONTAINING BUILDING MATERIAL SAMPLING

On September 10, 2019, Credere surveyed the Site building to locate materials that in Credere’s experience are likely to contain concentrations of Toxic Substances Control Act (TSCA)-regulated

PCBs exceeding the PCB bulk product waste criteria as defined by 40 CFR 761.3. Five samples of suspect PCB-containing building materials were collected (CA-PCB-1 through CA-PCB-5) using dedicated sampling tools. Sample locations are summarized in Table 2 and shown on Figure

1.

3. RESULTS

The following subsections present the results of the data collected during this HBMS.

3.1 ACM RESULTS

Laboratory analytical results for asbestos bulk samples were compared to the 1% limit specified in the Maine DEP Chapter 425. Material with concentrations of asbestos greater than 1% are considered ACM and are required to be abated per Maine DEP Chapter 425 prior to demolition or renovation of these materials. Material with concentrations of asbestos less than 1% but greater than 0% is considered asbestos-contaminated material and is not regulated as an asbestos waste.

A summary of collected asbestos sample results is provided in Table 1, and the complete laboratory analytical report is provided in Appendix B. A plan of the Site building and sample locations is attached as Figure 1.

During this survey, the following materials were identified to be ACM:

Approximately 450 square feet (sf) of concrete floor (CA-SACM-05) in Building 165

During this survey, the following materials were identified to be asbestos-contaminated materials:

Approximately 30 linear feet (lf) of black floor seam caulk (CA-SACM-04) in Building

3.2 PCB RESULTS

PCB sample results were compared to the 40 CFR 761.3 definition of PCB bulk product waste (50 milligrams per kilogram [mg/kg]), which are regulated for removal. Materials that have been analyzed to contain total PCBs at a concentration of equal to or greater than 1 mg/kg but less than

50 mg/kg are not regulated by TSCA for disposal as long as they remain in use. However, if these materials are removed from use, such as through demolition or renovation, they must be disposed at a facility that is licensed to accept this waste. Building materials that have been analyzed to contain total PCBs at a concentration of less than 1 mg/kg are unrestricted for future use and/or disposal.

A summary of collected PCB sample results is provided in Table 2, and the complete laboratory analytical report is provided in Appendix B. A plan of the Site building and sample locations is included as Figure 1.

During this survey, none of the materials tested exceeded the laboratory reporting limits; therefore, none exceeded the 50 mg/kg threshold for bulk product waste under TSCA.

4. CONCLUSIONS & RECOMMENDATIONS

Credere has performed a HBMS of Substation 7 and Building 165 at the PNSY in Kittery, Maine.

The primary purpose of this HBMS was to identify HBM that may be impacted by future demolition/renovation and document their location and quantity. The HBMS has met the following objectives:

Complete an ACM survey to identify ACM that may be impacted by future demolition/renovation

Complete a PCB-containing building materials survey to assess the need for special handling and disposal of certain demolition/renovation debris

4.1 SUMMARY

Credere’s conclusions considering the results of this HBMS include the following:

The following ACM were confirmed present during this HBMS:

o Approximately 450 square feet (sf) of concrete floor (Sample Identification

CA-SACM 5) in building 165.

No PCB-containing building materials exceeded the laboratory reporting limits and none exceeded the 50 mg/kg threshold for bulk product waste under TSCA.

4.2 RECOMMENDATIONS

Based on the findings and conclusions of this HBMS, Credere makes the following recommendations:

Properly remove and dispose the identified ACM during redevelopment of the Site.

Because no destructive methods were used to complete this survey, if any suspect untested

ACM are identified during renovation or otherwise, a supplemental asbestos survey should be performed.

5. LIMITATIONS

This report has been prepared as part of a contract agreement between Credere and the Client. This agreement was established in order to provide the Client with information upon which they can rely concerning the existence or likely existence of HBMs at the Site. This report does not reflect:

Conditions in inaccessible and/or otherwise untested areas

Variations in contaminant concentrations that can occur between sample locations

The potential presence of analytes that were not analyzed for or that may be present below the Practical Quantification Limits for the analytical method

Variations in conditions that occurred at a time other than when the Site inspection was completed

In the event that any conditions different from those described herein are encountered at a later time, Credere Associates, LLC requests an opportunity to review such differences and modify the assessment and conclusions of this report. This report was prepared expressly for the purpose described. The information in this report may not be suitable for any other use without adaptation for the specific purpose intended. Any such reuse of this report, without adaptation, shall be at the sole risk and liability of the party undertaking the reuse.

The ACM survey portion of this project was completed in accordance with relevant, applicable, and appropriate standards and was performed by exercising the degree of care and skill ordinarily exercised by a duly qualified or Certified Asbestos Inspector. However, there is a possibility that hidden, inaccessible, or otherwise unassessed ACM may exist at the Site. If suspect ACM is identified during any future Site operations including maintenance, renovations, housekeeping, or general demolition, the party performing these activities should first refer to this report. If conclusive results cannot be obtained, additional sampling and analysis must be conducted by a duly qualified or Certified Asbestos Inspector prior to the initiation of any activities that may impact or in any way disturb potential unassessed ACM.

Results contained within this report relate only to the samples submitted under this Alpha Lab Number and meet NELAP requirements for all

NELAP accredited parameters unless otherwise noted in the following narrative. The data presented in this report is organized by parameter

(i.e. VOC, SVOC, etc.). Sample specific Quality Control data (i.e. Surrogate Spike Recovery) is reported at the end of the target analyte list for each individual sample, followed by the Laboratory Batch Quality Control at the end of each parameter. Tentatively Identified

Compounds (TICs), if requested, are reported for compounds identified to be present and are not part of the method/program Target

Compound List, even if only a subset of the TCL are being reported. If a sample was re-analyzed or re-extracted due to a required quality control corrective action and if both sets of data are reported, the Laboratory ID of the re-analysis or re-extraction is designated with an "R" or "RE", respectively.

When multiple Batch Quality Control elements are reported (e.g. more than one LCS), the associated samples for each element are noted in the grey shaded header line of each data table. Any Laboratory Batch, Sample Specific % recovery or RPD value that is outside the listed

Acceptance Criteria is bolded in the report. In reference to questions H (CAM) or 4 (RCP) when "NO" is checked, the performance criteria for CAM and RCP methods allow for some quality control failures to occur and still be within method compliance. In these instances, the specific failure is not narrated but noted in the associated QC Outlier Summary Report, located directly after the Case Narrative. QC information is also incorporated in the Data Usability Assessment table (Format 11) of our Data Merger tool, where it can be reviewed in conjunction with the sample result, associated regulatory criteria and any associated data usability implications.

Soil/sediments, solids and tissues are reported on a dry weight basis unless otherwise noted. Definitions of all data qualifiers and acronyms used in this report are provided in the Glossary located at the back of the report.

HOLD POLICY - For samples submitted on hold, Alpha's policy is to hold samples (with the exception of Air canisters) free of charge for 21 calendar days from the date the project is completed. After 21 calendar days, we will dispose of all samples submitted including those put on hold unless you have contacted your Alpha Project Manager and made arrangements for Alpha to continue to hold the samples. Air canisters will be disposed after 3 business days from the date the project is completed.

Please contact Project Management at 800-624-9220 with any questions.

PCBs

L1941126-01 and -02: The sample has elevated detection limits due to the dilution required by the sample matrix.

L1941126-01: The surrogate recoveries are below the acceptance criteria for 2,4,5,6-tetrachloro-m-xylene

(0%) and decachlorobiphenyl (0%) due to the dilution required to quantitate the sample. Re-extraction was not required; therefore, the results of the original analysis are reported.

I, the undersigned, attest under the pains and penalties of perjury that, to the best of my knowledge and belief and based upon my personal inquiry of those responsible for providing the information contained in this analytical report, such information is accurate and complete. This certificate of analysis is not complete unless this page accompanies any and all pages of this report.

Limit of Quantitation: The value at which an instrument can accurately measure an analyte at a specific concentration. The LOQ includes any adjustments from dilutions, concentrations or moisture content, where applicable. (DoD report formats only.)

Method Detection Limit: This value represents the level to which target analyte concentrations are reported as estimated values, when those target analyte concentrations are quantified below the reporting limit (RL). The MDL includes any adjustments from dilutions, concentrations or moisture content, where applicable.

Matrix Spike Sample: A sample prepared by adding a known mass of target analyte to a specified amount of matrix sample for which an independent estimate of target analyte concentration is available. For Method 332.0, the spike recovery is calculated using the native concentration, including estimated values.

Matrix Spike Sample Duplicate: Refer to MS.

Not Applicable.

N-Nitrosodiphenylamine/Diphenylamine.

Not Ignitable.

Non-Plastic: Term is utilized for the analysis of Atterberg Limits in soil.

Reporting Limit: The value at which an instrument can accurately measure an analyte at a specific concentration. The RL includes any adjustments from dilutions, concentrations or moisture content, where applicable.

Relative Percent Difference: The results from matrix and/or matrix spike duplicates are primarily designed to assess the precision of analytical results in a given matrix and are expressed as relative percent difference (RPD). Values which are less than five times the reporting limit for any individual parameter are evaluated by utilizing the absolute difference between the values; although the RPD value will be provided in the report.

Standard Reference Material: A reference sample of a known or certified value that is of the same or similar matrix as the associated field samples.

Semi-dynamic Tank Leaching Procedure per EPA Method 1315.

Toxic Equivalency Factors: The values assigned to each dioxin and furan to evaluate their toxicity relative to 2,3,7,8-TCDD.

Toxic Equivalent: The measure of a sample's toxicity derived by multiplying each dioxin and furan by its corresponding TEF and then summing the resulting values.

Tentatively Identified Compound: A compound that has been identified to be present and is not part of the target compound list (TCL) for the method and/or program. All TICs are qualitatively identified and reported as estimated concentrations.

Spectra identified as "Aldol Condensates" are byproducts of the extraction/concentration procedures when acetone is introduced in the process.

The analyte was detected above the reporting limit in the associated method blank. Flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x) the concentration found in the blank. For MCP-related projects, flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x) the concentration found in the blank. For DOD-related projects, flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x) the concentration found in the blank AND the analyte was detected above one-half the reporting limit (or above the reporting limit for common lab contaminants) in the associated method blank. For NJ- Air-related projects, flag only applies to associated field samples that have detectable concentrations of the analyte above the reporting limit. For NJ-related projects (excluding Air), flag only applies to associated field samples that have detectable concentrations of the analyte, which was detected above the reporting limit in the associated method blank or above five times the reporting limit for common lab contaminants (Phthalates, Acetone, Methylene Chloride, 2-Butanone).

Co-elution: The target analyte co-elutes with a known lab standard (i.e. surrogate, internal standards, etc.) for co-extracted analyses.

Concentration of analyte was quantified from diluted analysis. Flag only applies to field samples that have detectable concentrations of the analyte.

Concentration of analyte exceeds the range of the calibration curve and/or linear range of the instrument.

The concentration may be biased high due to matrix interferences (i.e, co-elution) with non-target compound(s). The result should be considered estimated.

The analysis of pH was performed beyond the regulatory-required holding time of 15 minutes from the time of sample collection.

The lower value for the two columns has been reported due to obvious interference.

Estimated value. This represents an estimated concentration for Tentatively Identified Compounds (TICs).

Reporting Limit (RL) exceeds the MCP CAM Reporting Limit for this analyte.
