1.0 EXECUTIVE SUMMARY

Aerosol Monitoring & Analysis, Inc. (AMA) was contracted to perform a hazardous materials inspection of Building 9H, Generator 344, and the connecting corridor between Building 9H and 314C, located at the VA in Perry Point MD. The purpose of the investigation was to identify potential hazardous materials such as asbestos-containing materials (ACM), lead-based paint (LBP), polychlorinated biphenyls (PCB), mercury containing materials, lead in soil, and other potential hazardous materials that may be disturbed by the proposed demolition activities. Between October 16 and October 31, 2023, AMA representatives Ms. Nyasha Carter, Mr. Rohan McLaughlin, and Mr.

Andrew Washington were on-site to identify and evaluate potential hazardous materials. The inspection was conducted within three designated areas: 1) Building 9H, 2) Generator Building 344, and 3) Connecting Corridor between 9H and 314C.

1.1 ASBESTOS-CONTAINING MATERIALS

AMA collected forty (40) bulk samples of suspect ACMs, which were identified throughout the accessible interior and exterior areas of each of the three areas, which were not previously sampled. Of the 40 bulk samples collected, ten (10) were identified as containing greater than one percent (>1%) asbestos by polarized light microscopy (PLM) analysis. The EPA and the Maryland Department of Environment have determined that materials containing greater than (>) 1% asbestos are considered asbestos containing materials (ACM) and must be treated as such.

Based on the results of the inspection and previous inspection reports, ACM was identified and or assumed within the following materials:

1) Building 9H

Floor tile (Various 12”x12” and 9”x9”) Black floor tile mastic Brown mastic dots Cardboard pipe insulation Cloth duct vibration isolator Fire doors Red floor leveling Exterior stucco Exterior vent caulk White duct seam sealant on foil White duct seam sealant on metal White pipe seam sealant Exterior window and door caulk Window glazing Yellow carpet mastic Elevator cab/door insulation (assumed)

2) Generator Building 344

Gray metal duct seam sealant Gray louver caulk Roof shingle

3) Connecting Corridor Between 9H and 314C

Built-up roofing Window caulk/window glazing

The US EPA and State of Maryland require an inspection for asbestos be performed prior to renovation activities that may disturb such materials (EPA NESHAP 40 CFR Part 61, Subpart M). In addition, the building or facility owners are required to provide information regarding the presence quantity and location of asbestos containing materials to contractors bidding on or performing work at such facilities (OSHA Asbestos in Construction 29 CFR 1926.1101). The asbestos containing materials (ACM) identified throughout the three buildings must be removed if they will be disturbed by demolition activities.

1.2 LEAD-BASED PAINT

One hundred fifty-one (151) surfaces finished with suspect lead-based paint (LBP), including calibrations, were tested during the investigation of Building 9H and the Connecting Corridor Between 9H and 314C with the use of a SciAps X-550 Pb X-Ray Fluorescence (XRF) lead-based paint analyzer. Forty-eight (48) of the tests/surfaces/building components were determined to contain greater or equal to (>0.7) milligram of lead per square centimeter (mg/cm2) of surface area tested, the amount defined as a LBP according to the State of Maryland. The OSHA has determined that surfaces with measurable amounts of lead must be handled in accordance with the OSHA Lead in Construction Standard (29 CFR 1926.62)

In general, the following building components were identified to have LBP:

Metal window frame systems Wood transoms Terracotta walls Metal corner guards Wood window frame systems Metal handrails Concrete window sills Structural steel Metal cage doors Metal tank Metal vents Metal door frame systems Concrete riser Ceramic slop sink Plaster ceilings and walls Metal stall door Metal locker Metal stair systems

Wood door system Wood column

4) Connecting Corridor Between 9H and 314C and Building 344

No LBP identified

There is no regulatory requirement to remove components that have lead-based or lead containing paint prior to demolition. However, if these components are to be removed and disposed of, the Resource Conservation and Recovery Act (RCRA), 40 CFR 260-268 requires Toxic Characteristic Leachate Procedure (TCLP) testing of the waste stream for lead in order to determine if the material must be disposed of as a lead hazardous waste.

Any work that is conducted on painted surfaces with measurable amounts of lead must be done so in accordance with the OSHA Lead in Construction Standard 29 CFR 1926.62.

1.3 LEAD IN SOIL

While onsite, AMA collected soil samples from four sides of Building 9H. These samples were grab samples that were composites from several locations on each side of the building. The 4 samples were collected in accordance with ASTM Practice E1727-99 “Standard Practice for Field Collection of Soil Samples for Lead Determination by Atomic Spectrometry Techniques”.

The laboratory results for the 4 soil samples collected ranged from 40 mg/Kg to 480 mg/Kg (mg/Kg is also expressed as parts per million (ppm)). The results of the soil sampling indicate that none of the samples were found to have lead levels in excess of regulatory levels.

1.4 POLYCHLORINATED BIPHENYL’S

1.4.1 PCB BALLAST

Small capacitors and fluorescent light ballasts manufactured after 1978 have been labeled "NO PCB's" by the manufacturers. Prior to 1978, small capacitors and fluorescent light ballasts were not labeled as to whether they contained PCBs;

therefore, all unlabeled capacitors and ballasts were assumed to contain PCBs.

AMA identified and quantified light fixture ballasts throughout the site structures. AMA performed visual inspection of representative fluorescent light fixtures and observed the "No PCB's" label present on the assessed ballasts.

AMA does not anticipate ballasts to be PCB containing. Each light fixture should be inspected and appropriately disposed of during renovation/demolition activities if they are to be removed or replaced.

1.4.2 PCB CAULK AND PAINT

AMA collected ten (10) PCB in caulk and paint samples for laboratory analysis.

The PCB in caulk and paint samples were collected from window systems, door systems, exterior vents, and walls. The Toxic Substances Control Act (TSCA) enabled the EPA to enact regulations which control the use of PCBs within various building products. In accordance with 40 CFR 761, building applications containing PCBs at levels > 50 parts per million (ppm) or milligrams per kilogram (mg/Kg) are considered PCB contaminated caulk. Based on the results of the PCB caulk analysis, none of the samples were found to contain detectable concentrations PCBs, indicating that the building caulking and paint applications tested did not contain any regulated amounts of PCBs.

1.5 MERCURY VAPOR LAMPS

Reportable quantities of mercury are often found in fluorescent lamps. Because of this fact, the fluorescent lamps found in Building 9H and surrounding buildings, should be considered a universal waste for mercury lamps under the Resource Conservation and Recovery Act (RCRA); 40 CFR 273. Based on the observations at the site, it was determined that there are approximately one thousand one hundred five (1,105) fluorescent lamps throughout Building 9H and the Connecting Corridor. No fluorescent lamps were observed in Generator Building 344. No mercury switches were observed.

Unless Toxic Characteristic Leachate Procedure (TCLP) testing for mercury is performed, the light tubes located at the property should be assumed to exceed the regulatory limit of 0.2 milligrams per liter for mercury. These tubes must be disposed of as mercury containing (universal waste) unless testing proves otherwise.

1.6 OTHER POTENTIAL HAZARDOUS MATERIALS

Exit signs suspected to contain batteries or potential radioactive tritium sources exist within the building and shall be handled and disposed of properly. Additionally, AMA observed window air conditioning units throughout the building. These units contain refrigerant that will need to be properly extracted and recycled.

2.0 METHODOLOGY

2.1 ASBESTOS-CONTANING MATERIALS

2.1.1 SAMPLE COLLECTION

The initial phase of the evaluation for ACM involved the visual evaluation of the three inspection areas. After reviewing and compiling documentation pertaining to the materials in the buildings, a strategy to sample suspect materials was formulated.

The sampling involved observing accessible areas of the buildings and collecting bulk samples of suspect materials. Sample results can be found in Table I, which is attached to this report.

Samples were collected with a core bore or utility knife which was driven through the suspect material to the substrate to obtain a sample containing each discrete layer. The samples were then placed in sterilized “whirl-pak” bags and assigned unique identifiers, which were recorded on the bags and the bulk survey sampling sheets.

2.1.2 BULK SAMPLE ANALYSIS

Bulk samples were submitted to AMA Analytical Services, Inc. in Lanham, Maryland. AMA Analytical Services, Inc. is accredited by the National Institute of Standards and Technology (NIST) through the National Voluntary Laboratory Accreditation Program (NVLAP #101143) for bulk sample analysis and by the American Industrial Hygiene Association (AIHA #8863.)

Samples of bulk material were analyzed using PLM following the EPA, “Method for the Determination of Asbestos in Bulk Building Materials" (EPA/600/R-93- 116). PLM is an optical microscopic technique used to distinguish the different types of asbestos fibers by their shape and unique optical properties. The technique is based on the refraction of light from the various crystalline asbestos structures and observing the corresponding color changes through the microscope.

Sample analysis results are listed in Table I of this report.

2.1.3 CHAIN OF CUSTODY

A chain of custody form was completed for the bulk samples. The samples were logged in and assigned unique laboratory numbers. Upon completion of analytical services, AMA Analytical Services, Inc. retained the remaining sample materials.

2.2 LEAD-BASED PAINT

2.2.1 TESTING STRATEGY

The initial phase of the evaluation for LBP involved a visual evaluation of painted surfaces. After reviewing and compiling documentation pertaining to the materials inside the building, a strategy to test suspect surfaces was formulated.

2.2.2 XRF TESTING

The lead testing was performed with a direct reading instrument, the SciAps X- 550 Pb X-Ray Fluorescence (XRF) lead-based paint analyzer. This XRF contains a gold x-ray tube anode that releases radiation while energized when the instrument is pressed flatly against a surface and the operator engages the trigger.

If the paint contains lead, the radiation will stimulate the lead atoms to re-emit x-rays that are sensed by a detector in the unit. The XRF then converts these signals to a final reading in milligrams of lead per square centimeter of surface area (mg/cm2). The SciAps XRF is capable of achieving a ninety-five percent (95%) confidence level in the readings.

Calibration of the SciAps X-550 was conducted in accordance with the manufacturer’s instructions. Prior to obtaining readings from suspect surfaces, three (3) calibration readings taken in Quick Mode were performed on a calibration sheet and recorded. The calibration films used contain approximately

1.0 mg/cm2.

2.3 LEAD IN SOIL

The sampling was performed with a plastic centrifuge tube. The tube was pushed, with hand pressure, into the soil and the material was scooped into the tube and then deposited into a separate polyethylene bag and sealed. Sample numbers were recorded on the bags and on the “Lead in Soil” sampling survey sheet with the appropriate sample locations. Upon completion of the sample collection, the samples were submitted to AMA Analytical Services, Inc. located in Lanham, Maryland. The samples were analyzed for lead utilizing EPA Method 600/R-93/200(M)-7420. This method provides a result in milligram per kilogram (mg/Kg, parts per million) on a dry weight basis.

2.4 POLYCHLORINATED BIPHENYL’S

2.4.1 PCB BALLAST

A visual assessment of fluorescent light fixtures that may contain PCB was made by AMA throughout the VA Perry Point buildings. During the assessment, AMA dismantled and visually inspected representative fluorescent light fixtures and identified the "No PCB's" label present on the fluorescent light fixture ballasts assessed.

2.4.2 PCB CAULK/PCB PAINT

The window system, door system and vent caulk samples were collected with an unused utility knife and pliers which were driven through the material to obtain a sample. The paint samples were collected with a paint scrapper which was scrapped across the paint to obtain a sample. The samples were then placed in sterilized “whirl-pak” bags and assigned unique identifiers, which were recorded on the bags and the bulk survey sampling sheets.

PCB samples were submitted to Eurofins Analytics, Inc., located at 10329 Stony Run Lane, Ashland, Virginia. Bulk samples were analyzed for PCBs utilizing EPA method SW-846 8082. A chain of custody form was filled out for the bulk samples. The samples were logged in and assigned unique lab numbers. Upon completion of analytical services, Eurofins Analytics Inc. retained the remaining sample materials.

2.5 MERCURY VAPOR LAMPS

A visual assessment of equipment and articles that may contain hazardous materials was made by AMA throughout the building. During the assessment, AMA observed and quantified suspect mercury bulbs and mercury vapor lamps associated with fluorescent light fixtures. No sampling was performed of the lamps.

2.6 OTHER POTENTIAL HAZARDOUS MATERIALS

A visual assessment was conducted within the building and exit signs which may contain batteries or tritium were located throughout hallways and other areas of the building.

Additionally, window air conditioning units were observed throughout the building.

AMA did not perform sampling of any exit signs or the refrigerant used within the window air conditioning units.

3.0 RESULTS

3.1 ASBESTOS-CONTAINING MATERIALS

AMA collected 40 bulk samples of suspect ACMs, which were identified throughout the accessible interior and exterior areas of each of the three buildings. These ACMs had not been sampled in previous inspection reports. Of the 40 bulk samples collected, 10 were identified as containing greater than one percent (>1%) asbestos by polarized light microscopy (PLM) analysis. The EPA and the Maryland Department of Environment have determined that materials containing greater than (>) 1% asbestos are considered asbestos containing materials (ACM) and must be treated as such.

Based on the results of the inspection, ACM was identified and or assumed within the following materials:

12”x12” Brown with yellow streaks floor tile 12”x12” Tan with brown streaks floor tile 9”x9” Beige with brown streaks floor tile 9”x9” Brown with beige streaks floor tile 9”x9” Red with white streaks floor tile 9”x9” Tan with red streaks floor tile 9”x9” White with black streaks floor tile 9”x9” White with red streaks floor tile Black floor tile mastic Cloth duct vibration isolator Brown mastic dots Cardboard pipe insulation Fire door Red floor leveling Exterior Stucco Vent caulk White duct seam sealant on foil White duct seam sealant on metal White pipe seam sealant Exterior window and door caulk Window glazing Yellow carpet mastic Elevator cab/door insulation (assumed)

3) Connecting Corridor Between 9H and 314C

Built-up Roofing Window caulk/window glazing

3.2 LEAD-BASED PAINT

One hundred fifty-one (151) surfaces finished with suspect lead-based paint (LBP), including calibrations, were tested during the investigation of Building 9H and the Connecting Corridor Between 9H and 314C with the use of a SciAps X-550 Pb X-Ray Fluorescence (XRF) lead-based paint analyzer. Forty-eight (48) of the tests/surfaces/building components were determined to contain greater or equal to (>0.7) milligram of lead per square centimeter (mg/cm2) of surface area tested, the amount defined as a LBP according to the State of Maryland. The OSHA has determined that surfaces with measurable amounts of lead must be handled in accordance with the OSHA Lead in Construction Standard (29 CFR 1926.62)

In general, the following building components were identified to have LBP:

Metal window frame systems Wood transoms Terracotta walls Metal corner guards Wood window frame systems Metal handrails Concrete window sills Structural steel Metal cage doors Metal tank Metal vents Metal door frame systems Concrete riser Ceramic slop sink Plaster ceilings and walls Metal stall door Metal locker Metal stair systems Wood door system Wood column

2) Connecting Corridor Between 9H and 314C and Building 344

No LBP identified.

Refer to the Field Forms for a description of the location of the tests, components tested, color of paint, substrate, condition of paint, and results of the tests located in Appendix B of this report. Components finished with LBP are listed in the Positive XRF Readings Table II.

3.3 LEAD IN SOIL

The laboratory results for the 4 soil samples collected ranged from 40 mg/Kg to 480 mg/Kg (mg/Kg is also expressed as parts per million (ppm)). The results of the soil sampling indicate that none of the samples were found to have lead levels in excess of regulatory levels. These results are listed in Table 1, which is attached to this report.

For comparison purposes, the Maryland Department of the Environment has established the following standards for soil:

Residential Soil Screening Concentration - 200 mg/Kg Commercial Soil Screening Concentration - 550 mg/Kg

The laboratory results indicate that samples from all areas are below the clearance criteria established by the State of Maryland. Table IV, attached to this letter, lists the results for the lead soil samples.

Also enclosed, please find copies of the lead in soil sampling survey sheet and Lead in Soil Laboratory Certificate of Analysis.

3.4 POLYCHLORINATED BIPHENYL’S

3.4.1 PCB BALLAST

Small capacitors and fluorescent light ballasts manufactured after 1978 have been labeled "NO PCB's" by the manufacturers. Prior to 1978, small capacitors and fluorescent light ballasts were not labeled as to whether they contained PCBs;

therefore, all unlabeled capacitors and ballasts were assumed to contain PCBs.

AMA performed a visual evaluation of representative light fixture ballasts utilizing a random selection method. Any ballast absent of the “No PCB’s” label was assumed to contain PCBs. Based on this assessment, the ballasts observed by AMA had the “No PCB’s” label in various locations. No sampling was performed of the electric fluid within the equipment.

3.4.2 PCB CAULK/PAINT

The Toxic Substances Control Act (TSCA) enabled the EPA to enact regulations which control the use of PCBs within various building products. In accordance with 40 CFR 761, caulking or paint containing PCBs at levels > 50 parts per million (ppm) or milligrams per kilogram (mg/Kg) is considered PCB contaminated caulk or paint.

Based on the results of the PCB caulk and paint analysis, none of the samples collected from the building contained ≥50 ppm PCB, indicating that the caulking and paint are not PCB containing.

The comprehensive table, contained within this report, lists the sample number, the type of material collected, sample location, and the results of the laboratory analysis (See Table III). For a detailed description of the locations where the bulk samples were collected, refer to the “PCB Bulk Sampling Survey Sheets” located in Appendix C of this report.

3.5 MERCURY VAPOR LAMPS

Reportable quantities of mercury are often found in fluorescent lamps. Because of this fact, the fluorescent lamps found in Building 9H, Building 344, and the connecting corridor between 9H and 314C, should be considered a Universal Waste for mercury containing lamps under the Resource Conservation and Recovery Act (RCRA); 40 CFR

273. Based on the observations at the site, it was determined that there are approximately 1,105 fluorescent lamps throughout Building 9H and the Connecting Corridor. No fluorescent lamps were observed in Generator Building 344.

3.6 OTHER POTENTIAL HAZARDOUS MATERIALS

The EPA requires proper removal and disposal of exit signs that contain tritium. If batteries exist within these signs instead of tritium, the disposal will depend on the type of battery. A total of 35 exit signs were observed within the building.

EPA regulations (40 CFR Part 82, Subpart F) under Section 608 of the Clean Air Act include requirements for the safe disposal of refrigeration and air-conditioning equipment. These requirements are designed to minimize refrigerant emissions when these appliances are disposed. AMA observed 33 window air conditioning units at the building.

4.0 CONCLUSIONS

4.1 ASBESTOS-CONTAINING MATERIALS

The US EPA and State of Maryland require an inspection for asbestos be performed prior to renovation activities that may disturb such materials (EPA NESHAP 40 CFR Part 61, Subpart M). In addition, the building or facility owners are required to provide information regarding the presence quantity and location of asbestos containing materials to contractors bidding on or performing work at such facilities (OSHA Asbestos in Construction 29 CFR 1926.1101). Based on the results of the asbestos inspection, the identified materials must be abated if those materials will be impacted by renovation or demolition activities.

In dealing with asbestos materials during demolition projects, the Environmental Protection Agency (EPA) regulation 40 CFR Part 61, Subpart M (NESHAP), the Occupational Safety and Health Administration (OSHA) 29 CFR 1926.1101 (Asbestos in Construction Standard) and the COMAR 26.11.21: Control of Asbestos would be the primary regulations impacting the work.

Regulated asbestos-containing material (RACM) means (a) Friable asbestos material, (b) Category I non-friable ACM that has become friable, (c) Category I non-friable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading, or (d) Category II non-friable ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder by the forces expected to act on the material in the course of demolition or renovation operations regulated by this subpart.

Within the EPA’s National Emissions Standards for Hazardous Air Pollutants (NESHAP) Asbestos Regulations (40 CFR 61, Subpart M), all regulated asbestos-containing materials must be removed prior to renovation or demolition of a building if they are to be impacted by the renovation/ demolition activities.

The Occupational Safety and Health Administration (OSHA,) in 29 CFR 1926.1101.

“Asbestos in Construction” regulation, defines work involving the removal of asbestos-containing thermal system insulation (TSI) and surfacing material as Class I work. All other asbestos removal work would be defined as Class II work.

State of Maryland asbestos regulation requirements, COMAR 26.11.21 must be adhered to during asbestos abatement. In summary, these requirements include licensing of the abatement contractor, supervisor and workers, posting caution signs, establishing a regulated work area, utilization of personal protective equipment, utilization of a decontamination area, and notifying the Maryland Department of the Environment (MDE) 10 days in advance of an abatement project.

As the identified materials will be impacted by the demolition activities, then the asbestos materials would be required to be removed prior to disturbance. The removal would have to be conducted by trained and licensed asbestos abatement personnel utilizing approved engineering controls and personal protective equipment (PPE) established under the regulations.

AMA recommends all asbestos containing materials be removed by an accredited and licensed asbestos abatement contractor prior to the demolition of the building. The EPA will allow nonfriable asbestos containing materials to remain in place during demolition, however, the entire waste stream (to include concrete and steel) would be required to go to a landfill that accepts non-friable waste and no recycling of any of the building materials could occur.

While some destructive assessments behind walls and above ceilings occurred, AMA cautions that additional forms of asbestos may be located within inaccessible areas of the building not typically accessible without demolition occurring. Additional materials may be encountered during demolition activities.

4.2 LEAD-BASED PAINT

For projects which will disturb lead containing paint, the paint must be handled in accordance with the requirements established by the EPA and OSHA.

There is no federal requirement to remove lead paint prior to demolition activities, only that painted components be tested to determine the disposal requirements and that contractors be made aware of the existence of any paint containing lead in detectable amounts (lead containing paint, LCP), so their workers can be adequately protected.

Regulations established in OSHA’s “Lead in Construction Standard” (29 CFR 1926.62) must be adhered to during demolition and renovation of the surfaces finished with paint containing lead in detectable amounts. This standard established the permissible exposure level (PEL) for lead at 50 micrograms per cubic meter (ug/m3) as an eight-hour time weighted average (TWA); the action level has been established at 30 ug/m3 as an eight-hour TWA. This regulation also requires employers to use engineering controls and special work practices to reduce worker lead exposure to, at, or below the PEL. It also triggers several requirements regarding exposure monitoring, biological monitoring, and employee training when a worker is exposed to airborne lead levels at or above the action level.

All lead-containing waste is to be handled and disposed of as hazardous waste unless TCLP

(toxic characteristic leaching procedure) testing is performed and indicates otherwise. The waste shall be considered as hazardous when the concentration of lead exceeds 5 parts per million (ppm) by the TCLP.

4.3 LEAD IN SOIL

None of the composite soil samples were found to be elevated above the State of Mayland threshold for a commercial/public building of 550 mg/Kg of lead. No remediation of the soil is required for lead.

4.4 POLYCHLORINATED BIPHENYL’S

4.4.1 PCB BALLAST

No PCB PCB-containing light ballasts were observed at the site.

4.4.2 PCB CAULK/PAINT

Based on the results of the testing conducted by AMA, the caulk at the site was not PCB containing, therefore no further action is necessary.

4.5 MERCURY VAPOR LAMPS

The fluorescent lamps found at the site should be considered a Universal Waste for mercury containing lamps under the Resource Conservation and Recovery Act (RCRA); 40 CFR 273.

There are no specific training requirements for PCB and MVL removal and packaging, however, all workers should be trained in the hazards of mercury, as well as handling procedures. All thermostats within the building were observed to be spring operated and did not have mercury switches.

4.6 OTHER POTENTIAL HAZARDOUS MATERIALS

During removal of the exit signs, the demolition contractor shall determine if these signs have batteries or tritium. If batteries are found, a determination of the battery type shall be completed, and proper disposal of the batteries shall be made. If no batteries are found and tritium is the determined source, the signs must be removed intact and disposed of at a facility that handles radioactive waste.

All window air conditioners (and the ice machines) have refrigerant that must be removed and disposed of (or recycled) by trained employees. These units can not be disposed of until the refrigerant is extracted.
