1.0 INTRODUCTION

Borton-Lawson (BL), on behalf of the Department of the Army (“the Client”), performed a hazardous materials survey of the Vehicle Maintenance Division facility (Building 14) proposed for renovation (“the project area”) located at the Tobyhanna Army Depot, Tobyhanna Township, Monroe County, Pennsylvania. The project area was surveyed for asbestos-containing materials (ACM’s), lead-based paint (LBP), PCB containing light ballasts, mercury containing components and other possible hazardous materials. BL’s survey team performed the site survey activities on July 29th and 30th, 2020.

The hazardous materials survey was conducted as part of a building renovation project that may require potential hazardous materials to be removed prior to the work. The project area consisted of approximately 26,000 square feet of open work areas, storage areas, an office, breakroom and restrooms. The hazardous materials survey was limited to Building 14 and did not include other buildings at the Tobyhanna Army Depot outside of the Building 14 Renovation project.

2.0 ASBESTOS-CONTAINING MATERIALS (ACM)

Asbestos is a natural, fibrous material occurring in mineral deposits within the earth. Since asbestos fibers are flexible, a good insulator and resistant to heat, water and most chemicals, they have been mined for use in over 3,000 different products, including roofing materials, brake pads and linings, paper products, floor tiles and many heavy industrial products such as sealants, cement pipe, cement sheets, and insulation. Asbestos has been proven to cause lung cancer and mesothelioma in humans through inhalation exposure.

The EPA and the Occupational Safety and Health Administration (OSHA) are responsible for regulating environmental exposure and protecting workers from asbestos exposure. The Asbestos NESHAP regulation was established to protect the public by minimizing the release of asbestos fibers during renovation and demolition activities. The regulation requires that all RACM be removed from a building prior to commencement of renovation or demolition activities when the amount of RACM present is greater than or equal to 160 square feet, 260 linear feet, or 35 cubic feet. A 10-day written notification must also be made to the EPA prior to commencement of the asbestos abatement project.

An asbestos-containing material (ACM) is defined as a material that contains greater than 1% asbestos. Friable ACM is defined as a material which when dry, can be crumbled, pulverized, or reduced to powder by hand pressure. Non-friable ACM is defined as a material which when dry, cannot be crumbled, pulverized or reduced to powder by hand pressure. Non-friable ACM is divided into two separate categories. Category I Non-friable ACM includes asbestos-containing gaskets, packings, resilient floor coverings, resilient floor covering mastics, or asphalt roofing products containing more than 1% asbestos. Category II Non-friable ACM includes all other non-friable ACM such as asbestos cement shingles, asbestos cement tiles, transite wallboards, panels or pipes.

Regulated asbestos-containing material (RACM) is defined under 40 CFR 61.141 of the NESHAP as:

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 a material in the course of demolition or renovation activities.

2.1 METHODOLOGY

BL representatives, Mr. Brian M. Derenick (Certification #26170), and Ms. Leigh Ann Henry (Certification #057412), accredited Asbestos Building Inspectors in the Commonwealth of Pennsylvania, conducted an asbestos survey of the subject site. The purpose of the survey was to determine if special handling and/or disposal procedures of asbestos containing materials (ACM) would be required during any future renovation or demolition activity. BL performed a limited asbestos survey according to AHERA protocols

TYAD – Building 14 Renovations 3 September 21, 2020

P:\TYAD\2017\3101\001\05-REPORTS\HazMat\2 - HAZMAT_Report20200921.docx

(40 CFR 763) to visually assess for the presence of suspected asbestos-containing materials (ACM). BL did not conduct demolition of ceiling and wall surfaces as part of the asbestos survey. Inaccessible areas such as above ceilings or behind walls may not have been surveyed and therefore suspect ACM or other hazardous materials may not have been identified but may be present.

All areas and suspect materials that were readily accessible to the building inspector were assessed for asbestos content. Bulk samples of each suspect ACM encountered by the inspector were collected in randomly located areas. Non-destructive sampling methods were instituted to ensure the structural integrity of the building component was not destroyed. To collect a bulk sample, a clean sampling tool was used to obtain a "thumbnail sized" sample. This sample was placed in a single-use 2-mil plastic bag, sealed and labeled. The sampling tool was cleaned with an amended water solution and dried between each use. The sample was then packaged along with appropriate chain of custody and submitted to an accredited National Voluntary Laboratory Accreditation Program (NVLAP) laboratory for analysis of asbestos content.

Bulk samples were submitted to AMA Analytical Services, Inc., NVLAP #101143-0, in Lanham, Maryland for analysis via Polarized Light Microscopy (PLM), EPA 600 Method. A positive stop method was performed on duplicate bulk samples that were previously identified as ACM.

2.2 RESULTS

A total of one hundred fourteen (114) suspect ACM bulk samples were collected from building materials located throughout the structures present on the subject site and submitted to an accredited NVLAP laboratory for analysis. A total of three (3) samples or 2% of the 114 bulk samples of suspect ACM collected and submitted for laboratory analysis, were determined to contain ACM. The remaining 111 bulk samples (98%) were found to be Non-ACM. The analytical results, including the laboratory chain of custody, are presented in Appendix B.

The results of the survey, including the estimated quantities and locations of the regulated ACM identified in the specific areas of the bulk sample location are provided in Table 1. Estimated total quantities for ACM identified throughout the structure are provided in Table 2. Photo documentation of site is provided in Appendix A. A complete list of the bulk samples collected from suspect materials during the asbestos survey are provided in Appendix B.

2.3 CONCLUSIONS AND RECOMMENDATIONS

BL recommends that friable and non-friable ACM be removed as part of asbestos abatement activities prior to commencement of any proposed building demolition or renovation activity. Asbestos abatement work should be conducted by an asbestos abatement contractor and workers who are certified to perform said activities within the Commonwealth of Pennsylvania. Asbestos abatement work protocols should also be performed in accordance with all applicable federal, state and local regulations. Asbestos containing waste must be disposed of at an approved waste disposal facility.

3.0 LEAD-BASED PAINT (LBP)

Lead is a highly toxic metal that was used for many years in products found in and around our homes.

Lead may cause a range of health effects, from behavioral problems and learning disabilities, to seizures and death. Children six years old and under are most at risk, due to the rapid development of their bodies and the sensitivity of their brains and nervous systems.

Lead from paint chips and lead dust can be serious hazards in homes where lead-painted surfaces are deteriorated or do not receive proper maintenance. Childhood exposure to lead-based paint in residential homes is most common from paint that is peeling, chipping, flaking, chalking or cracking.

Lead-based paint may also be a hazard when found on surfaces that infant children can chew or which are considered high friction or impact surfaces such as windows and window sills; doors and door frames; stairs, railings, and banisters; and porches and fences.

The U.S. Environmental Protection Agency (EPA), the Occupational Safety and Health Administration (OSHA) and the US Department of Housing and Urban Development (HUD) are responsible for the regulation of lead exposure in the United States including the reduction of risks from lead-based paint and other sources of lead in the workplace and in residential homes. The EPA defined homes built prior to 1978 as “target housing” since many contain lead-based paint. In general, the older the home, the more likely it contains lead-based paint. The federal government banned lead-based paint from housing in 1978.

3.1 METHODOLOGY

BL representative, Mr. Brian M. Derenick, an accredited Lead Risk Assessor in the Commonwealth of Pennsylvania (License#004140), conducted a lead-based paint (LBP) survey at the subject site. BL completed a cursory lead paint survey of the subject site. A surface-by-surface lead paint survey was not conducted in accordance with the US Department of Housing and Urban Development (HUD) Standards as defined under the Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing Chapter 7: Lead-Based Paint Inspection, 2012 Revisions.

Two methods are available to the inspector in the analysis of lead painted surfaces including the use of an X-Ray Fluorescence Analyzer (XRF) or through the collection of paint chip samples. X-ray fluorescence (XRF) technology employs the use of an XRF analyzer, which provides a quick and nondestructive method to determine the presence of lead painted surfaces. X-ray fluorescence technology involves the measurement of characteristic x-rays emitted by different elements, including lead, in the sample material when it is illuminated by high energy photons (x-rays or gamma rays).

TYAD – Building 14 Renovations 5 September 21, 2020

P:\TYAD\2017\3101\001\05-REPORTS\HazMat\2 - HAZMAT_Report20200921.docx

The analysis of painted surfaces was performed using an Olympus Delta Professional X-Ray Fluorescence Analyzer (XRF) by personnel specifically trained in radiation safety related to operate the XRF. The instrument was calibrated against a known concentration of lead in paint (generally 1.0 mg/cm2) provided in a Standard Reference Material. The instrument is within calibration limits when the average of three samples is between 1.0 and 1.1 mg/cm2. Instrument calibration was completed prior to commencement of use of the XRF, and repeated between each floor or every two hours, whichever is greater, and at the completion of the survey. A copy of the technical data sheet for the Olympus Delta Professional XRF is included in Appendix C.

The inspector records the sample location and description information for each XRF reading on field data sheets. The sample number and sample result are recorded with the data for each reading. For example, a single reading collected from a red wood door casing is recorded on data sheets in the field as #1 (reading #), wood (substrate), door casing (building material), red (color), office (location),

1.20 mg/cm2 (result), intact (condition). Upon completion of testing for the day, the raw test data is reviewed and modified as necessary to more accurately reflect the testing combination.

In order to ensure accuracy and evaluate the quality of data generated by the XRF instrument, a Performance Characteristic Sheet (PCS) is provided with each instrument. The PCS provides information such as a precision and bias range, which may be experienced for readings dependent on such factors as the type of substrate tested. These ranges are also used to show the variability found between machines of the same model. In addition, a PCS provides information on the range at which positive, negative or inconclusive readings may be encountered.

In this case, the definition for lead-based paint is based upon that defined by the US Environmental Protection Agency (EPA) and US Department of Housing and Urban Development (HUD).

Positive: Lead is present at or above the EPA/HUD standard of 1.0 mg/cm2 by XRF, or 0.5% by dry weight, on one or more of the components.

Negative: Lead is not present on any of the components at or below the EPA/HUD standard of 1.0 mg/cm2 or 0.5%. Note that lead may still be present and hazardous leaded dust may be generated during modernization, renovation, remodeling, maintenance or other disturbances of painted surfaces.

In order to collect a paint chip sample, an inspector utilizes a metal sampling tool to collect a representative sample of all paint layers from a total surface area of 4 square inches (2’x2’ or 1’x4’ sample area). The inspector must ensure that all layers of paint be included in the paint chip sample.

The location, color, condition, component and substrate material are then recorded for each paint chip sample. Laboratory analysis is completed via flame atomic absorption (FAA).

3.2 RESULTS

BL conducted a lead-paint survey via XRF and visual observation of painted surfaces within the subject site. The majority of painted surfaces consisted of walls, window and door components. Painted surfaces on the majority of building components ranged from fair to intact condition. A total of 123 XRF readings (including calibrations) were collected from painted surfaces of the structures on the subject site. Of the 123 XRF readings, 22 readings were found to contain lead-based paint.

3.3 CONCLUSIONS/RECOMMENDATIONS

The following surfaces were positively identified to contain LBP:

• White and Cream metal structural cross and I beams

• Yellow concrete floor strip

• Yellow metal wall transition between work areas 1 and 2

• White metal window sills

• Yellow garage doorway

• Light green wooden door

• Beige metal door jamb and casing

Personnel working on surfaces that contain lead or other similar surfaces, which have similar painting history and which will be disturbed through methods which involve grinding, cutting or sanding, risk the potential of exposure to high levels of lead dust or fumes generated by these activities. Proper removal methods of building components are recommended in order to ensure worker exposure levels are maintained below OSHA and other federal or state regulatory requirements. Adequate personal protection should be provided to personnel working on these surfaces in order to reduce the risk of exposure to lead dust or fumes created during renovation or demolition activities.

During demolition work, environmental controls should be implemented to reduce the potential that lead-contaminated dust is generated. Demolition debris may be required to undergo a Toxicity Characteristic Leaching Procedure (TCLP) test per EPA guidelines to determine the characterization of hazardous waste material and to identify proper disposal methods as general solid waste or as hazardous waste prior to removal to a certified waste handling facility.

If a painted surface does not meet the definition of lead-based paint (i.e., 1.0 mg/cm2) based on EPA and HUD Standards, it may still contain lead, which when disturbed may generate lead dust greater than the maximum exposure concentration of 30 micrograms per cubic meter (30 ug/m3) of air established by the Occupational Safety and Health Administration's (OSHA) "Lead Exposure in Construction Rule (29 CFR 1926.62)."

BL recommends that a renovation/demolition contractor be informed of the presence of lead-based paint in the work area. Workers involved in demolition activities should have appropriate lead awareness training in accordance with all applicable regulations. If the removal of lead-based paint is the primary scope of the renovation/demolition project, it is recommended that only an accredited abatement contractor licensed in the Commonwealth of Pennsylvania perform the work. It is further recommended that environmental and personal monitoring be conducted during the removal process to determine the actual amount of worker exposure to lead dust during demolition activity and to establish the appropriate type and level of personal protection and environmental controls required. Generally, the demolition contractor performing the work should determine, through monitoring, the levels of personal protection and environmental controls needed for their work.

4.0 PCB CONTAINING LIGHT BALLASTS

Polychlorinated biphenyls (PCB’s) are a group of toxic, organic compounds, which were used in the manufacture of plastics and as insulating fluids in electrical transformers and capacitors. The use of PCB's was banned in the United States in 1979. PCB’s have been demonstrated to cause a variety of adverse health effects. PCB’s have been shown to cause cancer in animals and studies in humans raise further concerns which support the belief that PCB’s are a probable human carcinogen.

4.1 METHODOLOGY

Light ballasts are the electrical components at the end of fluorescent light fixtures under a metal overplate. Prior to 1978, ballasts were commonly manufactured with polychlorinated biphenyls (PCBs).

PCBs were used in fluorescent light ballasts because of their good electrical insulating capabilities.

Ballasts made after 1978 are usually marked "Non-PCB." BL conducted a cursory inspection of random light fixtures located throughout the building to identify light ballasts that may contain PCB’s.

4.2 RESULTS

During the completion of the hazardous materials survey, a number of light ballasts were randomly selected to ascertain the potential for PCB content. The overplate was removed from some of the light fixtures to determine if they were labeled non-PCB. Based on observations made, all (100%) of the light ballasts inspected were found to be labeled as “non-PCB” and it can be assumed that the majority of the light ballasts are non-PCB. Approximately three (3) light ballasts were inaccessible and appeared to have been part of the original construction. These ballasts should be assumed to contain PCB’s.

Building 14: Approximately 349 non-PCB light ballasts; 3 PCB-containing ballasts

4.3 CONCLUSIONS/RECOMMENDATIONS

The disposal of fluorescent light ballasts should be based upon the presence or lack thereof of PCBs and the condition of the ballasts (leaking, etc.). Individual light ballasts should be inspected prior to removal to determine if the ballast is labeled as “Non-PCB”. Ballasts not labeled as such should be assumed to contain PCB’s. The best option for Non-PCB ballasts is recycling. Ballasts labeled as “Non- PCB” may be handled and disposed of as non-hazardous waste if recycling is not the preferred option.

The best alternative for non-leaking PCB ballasts is to recycle them at an EPA-approved recycling facility. Non-leaking PCB ballasts that are not recycled must be handled and disposed of as hazardous waste. Leaking PCB ballasts should be handled with extreme caution to avoid exposure, contamination and liability and also must be managed as PCB waste and disposed in a facility regulated under the federal Toxic Substances Control Act (TSCA). All applicable federal, state and local regulations should be followed in the handling and disposal of both Non-PCB and PCB containing ballasts.

5.0 MERCURY CONTAINING COMPONENTS

Mercury is a naturally occurring, silver metallic substance which occurs in deposits throughout the world and it is harmless in an insoluble form, such as mercuric sulfide. Mercury is poisonous in soluble forms such as mercuric chloride or methyl mercury. Mercury is considered to be a probable human carcinogen and human exposure is most prevalent through inhalation of mercury contaminated dust or fumes or skin absorption.

5.1 METHODOLOGY

Mercury is used in several building components including fluorescent lamps and liquid thermometers. In fluorescent light fixtures, mercury-containing dust forms when mercury vapor found within the lamps is excited by an argon or neon gas that produces a visible fluorescent light. The mercury dust then collects inside the fluorescent lamp bulb and can be released during breakage into the environment.

BL inspected the structures for the presence of fluorescent lighting and mercury containing thermometers.

5.2 RESULTS

Based upon completion of the hazardous materials survey, it was observed that the following conditions were found in regards to fluorescent lamps in the buildings:

Building 14: Approximately 649 fluorescent light bulbs

5.3 CONCLUSIONS/RECOMMENDATIONS

The mercury containing fluorescent lamps should be removed and recycled according to regulatory guidelines at an appropriately licensed recycling facility. Mercury containing waste components are considered a universal waste in the Commonwealth of Pennsylvania. Fluorescent lamps that are not recycled should be disposed of as hazardous waste, if not determined to be non-hazardous through TCLP analysis, at an approved disposal facility in accordance with all applicable federal, state and local regulations.

6.0 OTHER HAZARDOUS MATERIALS

A hazardous material is defined as a material that can be described as corrosive, explosive, reactive, flammable or toxic. Hazardous materials in various forms can cause death, serious injury, long-lasting health effects to humans, and damage to buildings, homes, and other property. Many products containing hazardous chemicals are routinely used and stored in industrial facilities, commercial businesses and homes. These products are also transported daily on the nation's highways, railroads, waterways, and pipelines. Chemical manufacturers are one source of hazardous materials, but there are many others, including service stations, hospitals, dry cleaners and hazardous materials waste sites.

6.1 METHODOLOGY

BL inspected the subject site for the presence of hazardous materials that may be present, including substances such as paints, refrigerants, coolants, petroleum products and sealants.

6.2 RESULTS

BL observed various hazardous substances within the project area, including household cleaners, hydraulic fluid, diesel oil, used oil, antifreeze, rock salt, coolant and vehicle batteries. The substances ranged from household sized containers to 55-gallon drums. A 55-gallon drum labeled as non-friable asbestos was observed in the project area. This drum was not sampled due to it being part of the facility operations and proper handling and disposal process, as well as, it not being of the building renovation project. It is assumed the drum contains asbestos containing materials that are encountered during the routine vehicle maintenance services (i.e., brakes) conducted on site.

P:\TYAD\2017\3101\001\05-REPORTS\HazMat\2 - HAZMAT_Report20200921.docx

6.3 CONCLUSIONS/RECOMMENDATIONS

Hazardous materials present on the subject site would be anticipated to consist of those types, sizes and quantities of those compounds that are used in typical maintenance activities for a vehicle maintenance facility. Hazardous substances present on the subject site should be disposed of properly as hazardous or non-hazardous waste at an approved recycling or disposal facility. The treatment, storage, disposal and use of these materials should be maintained in accordance with all applicable federal, state and local regulations.

7.0 ABATEMENT COST ESTIMATION

The following cost estimations are for the abatement of hazardous materials identified during the survey of the subject site. Cost estimation for the hazardous materials identified provides unit costs and estimated total costs for the removal and disposal of identified materials. The cost estimation is based on current industry pricing and standards for the abatement of hazardous materials under similar market conditions. However, the costs provided are based on our professional opinion and should be used for approximate budgetary purposes only. Formal cost estimates should be field verified and obtained from a certified abatement contractor(s) prior to the commencement of abatement activities. Actual quantities included in the abatement cost estimation may vary based upon materials identified during the future renovation or demolition of the structure present on the subject site.

The following abatement costs are for the removal and disposal of asbestos containing materials identified within the subject site:

The following footnotes only apply to those samples which the total asbestos result is flagged with a note number.

TEM RECOMMENDATION - Please note, due to resolution limitations with optical microscopy and/or interference from matrix components of this sample, results which are reported via PLM as negative or trace (<1%) for asbestos may contain a significant quantity of asbestos. It is recommended that the additional analytical technique of TEM be used to check for asbestos fibers below the resolution limits of optical microscopy.

MATRIX REDUCTION RECOMMENDATION - Please note, due to interference from the matrix components of this sample, results which are reported via PLM as negative or trace…
