1.0 INTRODUCTION

Mabbett and Associates, Inc. (Mabbett®) performed a survey for hazardous building materials as part of the pre-renovation evaluations of building materials for the B300 Roof and HVAC Repair project at the Portsmouth Naval Shipyard located in Kittery, Maine, Contract No. N40085-21-D-0005. The purpose of the survey was to assess the building for the presence of hazardous and regulated building materials, including asbestos-containing materials (ACMs), lead containing paint (LCP), RCRA 8 metals and other hazardous materials (OHMs). The survey was performed by Mr. Kevin M. Donovan and Mr. Jacob T. Walsh of Mabbett on June 26th, 27th, and 28th, 2023.

Additional survey work was conducted on October 11th, 2023, and consisted of the following activities:

▪ An Asbestos Containing Material (ACM) survey of suspect materials (analysis using polarized light microscopy [PLM]) and PLM NOB with gravimetric reduction preparation method for analysis of Non- Friable Organically Bound (NOB) materials.

▪ Lead Containing Paint (LCP) sampling (analysis by atomic absorption [AA] spectroscopy).

▪ Paint sampling for Cadmium and Chromium (analysis by Inductively Coupled Plasma [ICP]).

▪ Polychlorinated Biphenyls (PCB) Containing Building Materials Sampling (analysis performed by SW-846 Method 8082A).

▪ Dust wipe sampling for RCRA 8 (Resource Conservation and Recovery Act) metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver (analysis by ICP); and

▪ A visual estimation and inventory of universal waste and other hazardous materials (OHM).

At the time of the survey B300 was occupied. Areas that could be affected by upgrades and repairs to the electrical, HVAC and fire protection systems and replacement of the roof were surveyed. Areas and materials outside of this scope of work were not surveyed by Mabbett. All hazardous material investigations, surveying, testing, and reporting comply with Mabbett’s, Hazardous Materials Sampling Plan (HMSP) dated June 15, 2023_Rev 2.

1.1 Purpose and Objectives

This hazardous building material survey was comprised of four primary project tasks including:

▪ Evaluation of existing site conditions and formulation of a sampling plan.

▪ Site survey to collect building material samples for laboratory analysis.

▪ Conduct visual assessment and develop inventory of universal waste and other hazardous materials.

▪ Development of this Hazardous Building Materials Survey Report.

This inspection was designed to accomplish three primary objectives: (1) to collect a representative number of building materials for laboratory analysis and reporting (2) conduct visual assessment and develop an inventory of universal waste and other hazardous material; and (3) to use data from the laboratory analysis efforts to estimate the volume of hazardous and regulated building materials present within the building’s interior and roof for subsequent use in development of an abatement scope. These three objectives were met through a combination of a site inspection to collect building material samples and dust wipe samples for laboratory analysis;

interpretation of qualitative data collected in the field; and the quantitative laboratory data generated from analysis of the building materials samples as summarized in this survey report and create a universal waste inventory.

1.2 Background Information

B300 is a mixed-use building used primarily for industrial manufacturing with an overall area of 168,900 square feet. Plans for the building include upgrades and repairs to the electrical, HVAC and fire protection systems and replacement of the roof.

1.3 Summary of Survey Results

As required by State and Federal regulations, bulk samples of suspected ACM were collected by Mabbett and submitted using chain of custody (COC) procedures to Aerobiology of Woburn, Massachusetts. Aerobiology is a Maine certified asbestos analysis laboratory that is accredited by the American Industrial Hygiene Association (AIHA) and participates in the National Voluntary Laboratory Accreditation Program (NVLAP Lab Code 200090-0).

The Maine Department of Environmental Protection (Maine DEP) define any material that contains greater than or equal to one percent (>1%) asbestos as ACM.

Paint chip samples and dust wipe samples were collected by Mabbett for analysis using AA spectroscopy and ICP and submitted using COC procedures to Scientific Analytical Institute, Inc (SAI) of Greensboro, North Carolina. 19 paint chip samples were not analyzed for Chromium of Hexavalent Chromium and 3 samples were not analyzed for Cadmium due to insufficient amounts of material being collected during initial survey efforts. Follow up visits were conducted with additional tools in order to ensure that the required amount of material was collected for each sample. Similar paint colors and substrates indicated that initial results provided a sufficient amount of data to identify the appropriate level of information for waste characterization and worker protection needed prior to the disturbance of the material during construction/renovation activities, and therefore additional sampling was not warranted during this survey.

PCB building material samples were collected and submitted under COC procedures for PCB extraction using Analytical method 3660B to Alpha Analytical of Westborough, Massachusetts. Alpha is certified by the National Environmental Laboratory Accreditation Program (NELAP).

Current survey efforts yielded the following results:

▪ Ninety-nine-nine (99) bulk samples for suspect ACM were collected for laboratory analysis and reporting.

Two (2) materials were determined to contain asbestos.

▪ Twenty-nine (29) paint chip samples were collected from painted building surfaces for laboratory analysis and reporting. Zero (0) revealed concentrations of lead in paint that exceed the U.S. Department of Housing and Urban Development (HUD) threshold of 0.5 percent by weight.

▪ 15 Dust wipe samples analyzed for RCRA 8 metals.

▪ Eight (8) suspect PCB building material samples were collected and submitted for laboratory analysis as part of this survey. Based on laboratory analysis the materials were non-detect for PCBs above the TSCA regulated material threshold.

▪ An Inventory of universal waste and other hazardous materials was developed and provided in this inspection report in Section 5. An Inventory of other hazardous materials can be found in Table 4, Inventory of OHMs.

2.0 ASBESTOS CONTAINING MATERIAL SURVEY

The asbestos survey was performed from June 26th to June 28th 2023, and on October 11th, 2023 by Mabbett’s Maine licensed asbestos inspectors, Mr. Kevin M. Donovan (AI-0415) and Mr. Jacob T. Walsh (AI-0917). Prior to collecting samples, a visual screening assessment was conducted to identify locations of suspect ACM and develop a sampling plan. Only areas that were accessible during the field work phase were included in the survey, with reasonable efforts made to access areas needed to complete the asbestos survey and sampling program. Any unsampled or new suspect materials discovered during demolition activities must be sampled and submitted to a laboratory for analysis. Destructive investigation of operating equipment was not conducted.

2.1 Sampling Methodology

Mabbett complied with the following requirements:

▪ Samples were collected in accordance with applicable EPA, OSHA, and state regulations preventing airborne exposure to asbestos fibers to the extent possible. The sampling locations were repaired by Mabbett.

▪ The amount of sample collected was of sufficient size for analysis. Each layer was analyzed separately.

▪ Field personnel properly donned and doffed appropriate PPE where hazards existed and were identified.

▪ Mabbett performed the inspection between normal duty hours of 8:00 a.m. and 4:00 p.m.

▪ Bulk samples for asbestos analysis were collected using EPA National Emissions Standards for Hazardous Air Pollutants (NESHAP), 40 CFR Part 763, and Asbestos Hazard Emergency Response Act (AHERA) protocols. Bulk suspect ACM sampling was conducted according to the following standard sampling protocol:

▪ Friable surfacing material:

▪ At least three bulk samples shall be collected from each homogeneous area of surfacing material that is 1,000 ft2 or less.

▪ At least five bulk samples shall be collected from each homogeneous area of surfacing material that is greater than 1,000 ft2 but less than or equal to 5,000 ft2.

▪ At least seven bulk samples shall be collected from each homogeneous area of surfacing material that is greater than 5,000 ft2.

▪ Thermal system insulation:

▪ At least three bulk samples shall be collected from each homogeneous area of thermal system insulation.

▪ At least three bulk samples shall be collected from each homogeneous patched area of thermal system insulation.

▪ Sufficient samples shall be collected from elbows and fittings.

▪ Bulk samples shall not be collected from any homogeneous area where the state-licensed asbestos inspector determines that the thermal system insulation is fiberglass, foam glass, rubber, or other non-

ACM.

▪ Miscellaneous material (e.g., joint compound, roofing, gaskets, floor coverings, decorative coatings, wire insulation):

▪ At least three bulk samples shall be collected from each homogeneous area of miscellaneous material that is less than 100 ft2.

▪ At least three bulk samples shall be collected from each homogeneous area of miscellaneous material that is greater than 100 ft2.

The survey included accessible interior areas, the roof, and materials associated with the upgrades and repairs to the electrical, HVAC, and fire protection systems of the building.

Areas with limited access or where the survey was limited to visual observation only:

▪ within enclosed pipe/duct chases

▪ inside mechanical equipment

▪ energized electrical equipment

2.2 Analytical Methodology

Ninety-nine (99) bulk samples were collected from twenty (20) homogeneous areas from B300 and submitted using COC procedures to Aerobiology. Bulk samples were analyzed by PLM using EPA Method 600/R-93/116 using stop positive methodology and PLM NOB with gravimetric reduction preparation method for analysis of Non- Friable Organically Bound (NOB) materials, as required by the State of Maine Department of Environmental Protection. Sampling locations are depicted in Figures RBM-1, 2 ,3, & 4.

2.3 ACM Results

The EPA, Occupational Safety and Health Administration (OSHA), and the Maine Department of Environmental Protection (Maine DEP) define any material that contains greater than or equal to one percent (>1%) asbestos as ACM. Three (3) of the materials sampled and analyzed by PLM as part of this survey effort were found to contain greater than or equal to one percent (>1%) ACM. Bulk Sample Results are provided in Appendix A. The laboratory report and COC documentation are provided in Appendix B.

Estimated quantities of materials identified as ACM during this survey are presented in Table 1.

3.0 LEAD, Cadmium, and Chromium CONTAINING PAINT SAMPLING

Lead, Cadmium, and Chromium sampling was conducted by collecting and analyzing paint chips from painted surfaces and systems that may be impacted by the planned renovation.

3.1 Sampling Methodology

Paint chip samples were collected using a sharp hand tool to score and peel paint off an approximate 1 square inch area of the substrate. Different tools such as chisels, putty knives, and hammers may also be needed in the collection of paint chips. All tools were cleaned after each sample to prevent cross contamination. Collected paint chip samples were submitted under COC procedures to an accredited laboratory and analyzed via flame atomic absorption (AA).

3.2 Analytical Methodology

The regulations addressing Lead, Cadmium, and Chromium in non-residential buildings are focused on occupational exposures involved with paint-disturbing activities and related waste-disposal activities.

Occupational exposure to lead is regulated by OSHA regulation 29 CFR 1926.62, Lead in Construction, as well as other applicable state and local regulations.

A paint chip survey cannot determine a safe level of lead for the purpose of paint-disturbing/waste-disposal activities but is intended to provide guidance as to the locations of surfaces containing lead, cadmium, and hexavalent chromium.

Contractors may use this information to better determine where worker exposures to airborne lead and other hazards may occur. They can then assess the potential magnitude of exposure to their employees and identify the controls necessary to limit health risks. This information can also be used for pre-characterization of demolition waste streams prior to toxicity characteristic leaching procedure (TCLP) sampling in accordance with 40 CFR Part 261.

Twenty-nine (29) samples, each from a different homogenous areas were collected during this survey. Paint chip samples were submitted using COC procedures to Scientific Analytical Institute (SAI) for analysis. Analysis was conducted using EPA SW-846 Test Method 7000B: Flame Atomic Absorption Spectrophotometry and EPA SW-846 3050B: Inductively Coupled Plasma (ICP).

3.3 Sampling Results

OSHA regulations have no low-level threshold, therefore any result above the detection limit should be given proper consideration for worker safety and potential for risk. The results of this LCP sampling survey identify samples that indicate risk and are presented in Table 2. The laboratory report and COC documentation are provided in Appendix C.

4.0 DUST SAMPLING (RCRA 8 METALS)

Dust sampling for RCRA 8 metals was conducted by collecting and analyzing dust wipes from the interior, exterior, and on top of HVAC systems that may be impacted by the planned renovation.

4.1 Sampling Methodology

Dust wipe sampling for RCRA 8 metals was conducted on representative surface areas of the B300 ductwork utilizing a 10cm x 10cm template (100 square centimeters). Each sample was collected by wiping in a back and forth “S” pattern over a measured sampling area using a method approved “Ghost Wipe”. Then, the wipe was folded over itself, and the area was wiped again in a direction perpendicular to the first wipe orientation. The wipe sample was then placed into a labeled, clean bag for laboratory analysis. Samplers changed gloves between each sample. The proposed sampling scheme, the number of samples, the sample distribution and general methodology was developed by Mabbett and Associates and is documented in the Hazardous Materials Sampling plan. Specific sample locations were determined by field personnel while on-site prior to sample collection. Ducts were sampled approximately 10-15 feet off the ground and were accessed utilizing a step ladder and cordless drill.

Samples were taken inside of the duct and directly off the duct grille.

4.2 Analytical Methodology

Dust samples were analyzed utilizing Inductively Coupled Plasma (ICP) NIOSH 7303/EPA SW-846 3050B and Cold Vapor Atomic Absorption OSHA ID -145. The purpose of this testing was to characterize the presence and concentration of RCRA 8 metals in areas of the building that may impact the project.

4.3 Dust Sampling Results

Any surfaces with heavy metal containing dust present should be managed in accordance with PNSY guidelines, PSHA worker safety rules, and State and EPA regulations. OSHA construction rules do not specify acceptable levels of heavy metals within dust for occupational exposure. Construction work involving heavy metals in dust must be completed in accordance with OSHA regulations. Contractors conducting work in areas where heavy metals are present should be notified, and proper work protocols should be used. Sampling yielded the following results presented in Table 3.

Polychlorinated Biphenyls (PCBs) can be found in some common building materials manufactured during the1950s, 1960s and 1970s. If PCB concentrations in building materials exceed regulatory thresholds, abatement is typically required when the use of PCBs in building materials is defined by the EPA to be an “unauthorized use”.

Disposal of materials with regulated concentrations of PCBs is governed by TSCA regulations. In many cases, if PCBs are discovered in building materials, a remediation work plan for these materials must be approved by the EPA prior to implementation. Based upon the age of the buildings, the building materials most likely to contain PCBs are window or other caulking materials, and waterproofing paints or sealants. PCBs in transformer fluid represent an authorized use under the TSCA regulations and must also be disposed of as PCB waste. Releases of transformer fluids to building materials must be assessed, and remediation plans developed and approved by the EPA prior to implementation.

Inspection and representative sampling of suspect building materials was conducted as part of this hazardous building materials survey. The survey for PCBs included the sampling of paint and mastic materials that may be impacted by the proposed work. Collected samples were submitted using COC procedures to Alpha. Analysis was conducted using Extraction Method EPA 3540C. Laboratory analytical reports are included in Appendix E. Results of the PCB sampling are presented in Table 4.

6.0 INVENTORY OF OTHER HAZARDOUS MATERIALS

A visual screening was conducted by Mabbett to identify quantities of universal waste and other potential hazardous materials in order to define an inventory of these materials for future relocation or disposal purposes.

The survey included a visual estimation of the following suspect materials:

▪ Light Ballasts (associated with fluorescent light tubes)

▪ Light Tubes (e.g., fluorescent light tubes and HID lamps that may contain mercury or lead)

▪ Switches (i.e., mercury switches or gauges)

A summary of this visual inventory is presented in Table 5.

7.0 RECOMMENDATIONS

This section presents a summary of the conclusions and recommendations from the pre-renovation hazardous building materials survey at the Portsmouth Naval Shipyard, B300. Prior to initiating plans for renovation activities, survey results for the Pre-Renovation Services presented herein should be reviewed to determine whether any of the identified regulated building materials will be disturbed by proposed work activities.

7.1 Asbestos

The planned renovation of B300 will disturb the ACM listed in Table 1 and will require removal of these materials by a licensed asbestos abatement contractor prior to being disturbed. The survey included accessible interior areas, the roof, and materials associated with the upgrades and repairs to the electrical, HVAC, and fire protection systems of the building. Any suspect materials encountered during renovation activities that were not identified in this report as being non-ACM should be assumed to be ACM unless sample results prove otherwise.

7.2 Paint

The purpose of the Lead, Cadmium, and Chromium screening survey was to identify patterns of lead, cadmium, and chromium containing paint. For the purpose of this screening survey a limited amount of representative interior building components were tested. The regulations addressing heavy metals in paint in non-residential buildings are focused on protecting workers involved with paint-disturbing activities and related waste-disposal activities.

Occupational exposure to lead in construction is regulated by OSHA regulation 29 CFR 1926.62 “Lead in Construction”, as well as other applicable state and local regulations. These regulations involve the air monitoring of workers to determine exposure levels when disturbing paint containing measurable concentrations of heavy metals. A paint chip survey cannot determine the safe level of lead for the purpose of paint-disturbing activities but is intended to provide guidance as to the locations of heavy metals in paint. Exposure to heavy metals may cause a wide range of health effects, from behavioral problems, learning disabilities, seizures, and death.

Employers and contractors may use this information to better determine where worker exposures to airborne heavy metals may occur and, through the interpretation of heavy metals concentration data, assess the potential magnitude of exposure to their employees and identify the controls necessary to limit health risk.

Representative samples of heavy metals waste to be generated during building renovation, or following demolition but prior to disposal, should be collected and analyzed using toxicity characteristic leaching procedure (TCLP) in accordance with 40 CFR Part 261. Management and disposal of lead containing waste must be done in accordance with all applicable local, state, and federal regulations. OSHA regulations may require certain procedures for any paint that contains heavy metals, even if it is below these levels. All materials identified, regardless of their heavy metals content, should either be sampled and analyzed by TCLP and then handled/disposed of accordingly, or segregated from other large-scale debris and then managed as hazardous waste in accordance with federal, state, and local hazardous waste disposal regulations.

7.3 Dust Sampling (RCRA 8 Metals)

Surfaces sampled contained varying amounts of lead, cadmium, chromium, and other hazardous metals that may be regulated by RCRA and OSHA when disturbed by renovation, alteration, repair, or demolitions activities.

Thresholds, exposures, and engineering controls for cadmium, chromium, or other hazardous metals differ depending on factors including, but not limited to, whether paints are used in operational processes, are painted surfaces of building components or exterior coatings and are disturbed during construction activities. Most of the dust observed during sampling was observed to be non-oily. An image of the typical dust observed is provided in Appendix D. The sample collected at Column D19 was observed to be oily at the time of the investigation. No

© 2023, Mabbett & Associates, Inc. Page 16 September 11, 2024 other notable characteristics were observed during sampling efforts. When investigation, sampling, renovation, or demolition occurs, there are hazards associated with the generation of dust, debris, and fumes. The OSHA Standards cite requirements for work activities that can create an unsafe condition with regards to worker protection. These include, but are not limited to manual demolition, paint scraping, power tooling without dust collection, cleanup activities with dry abrasives, movement or removal of enclosures, abrasive blasting, welding, cutting, and burning on steel structures. Samples contained concentrations of RCRA 8 metals above laboratory reporting limits. Based on the dust wipes and lead sampling results and to limit personnel exposure to dust during duct removal activities a Mabbett’s staff CIH believe that, while we can’t say what the airborne concentrations of these metals will be during demolition, dust will present some hazards. Some recommendations that can be used in various combinations based on the chosen work will be the use of half-face respirators with P100 cartridges (purple) during activities where dust may be generated. Without conducting air sampling when the project starts, this would just cover the worst-case scenario of at least one metal’s concentration would be above OSHA’s PEL or any other government recommended levels. The use of HEPA-filtered vacuum cleaners to remove the dust without releasing back into the air and HEPA filtration for exhausted air. Wet methods for demolition, wetting the dust will keep most of it from becoming airborne. Sealing off the work area with appropriate sheeting (6-mil should be sufficient). After the work is completed, clean the area using wet mop methods and conduct clearance wipe sampling.

7.4 Polychlorinated Biphenyls

Materials containing PCBs were identified. None of the materials sampled contain greater than 50 parts per million PCB. These materials are considered non-TSCA regulated PCB Bulk Product Waste and to meet the TSCA Excluded PCB Product definition. Excluded PCB Product waste can be managed as solid waste at any landfill permitted to accept waste with PCB levels up to those observed.

7.5 Other Hazardous Materials

The purpose of the inventory for other hazardous materials as completed by Mabbett was to identify potential hazardous, and non-building material substances that may require special handling consideration prior to any planned building renovation. Mabbett identified items, that if removed, should be disposed of or recycled in accordance with applicable Federal and State rules for regulated materials. Examples of such materials are light ballasts and fluorescent light tubes.
