EXECUTIVE SUMMARY

Jacobs Engineering Group, Inc. (Jacobs) retained Sci-Tek Consultants, Inc. (Sci-Tek) to conduct asbestos and lead-containing paint surveys of the Naval Support Activity, Building 608B, Locomotive and Train Shed located in Mechanicsburg, Pennsylvania. The scope of the surveys was limited to Sci-Tek’s investigation and sampling of suspect Asbestos Containing Materials (ACMs) and lead-containing paints.

The asbestos and lead paint survey was performed on November 13, 2017 by Pennsylvania Licensed Asbestos Building Inspector / Management Planner / Project Designer (PA ID #030760) and Lead-Based Paint (LBP) Inspector / Risk Assessor (PA ID #002454) Paula South, and Pennsylvania Licensed Asbestos Building Inspector / Management Planner (PA ID #054656) and Lead-Based Paint (LBP) Inspector / Risk Assessor (PA ID #057037) Eric Bordenick.

Sampling of suspect ACM was performed in accessible areas throughout the building. Suspect ACM samples included interior and exterior board sheeting, window caulking, door caulking, cove base, floor tile, mastics, sheetrock, and pipe insulation. Analysis of the samples consisted of polarized light microscopy analysis via EPA Method EPA 600/R-93/116, with point counting of samples below 10%.

The survey results are as follows:

Sampled materials that tested positive for asbestos:

• Exterior board sheeting at 20% Chrysotile, approximately 13,000 square feet, located on the exterior siding and soffit.

• Exterior window caulking at 4.4% and 4.7% Chrysotile, approximately 2,000 linear feet, located on the exterior windows.

• Exterior door caulking at 4.6%, 1.4%, and 5.3% Chrysotile, approximately 100 linear feet, located on the front exterior garage door.

• Exterior door glazing at 5.6% and 5.1% Chrysotile, approximately 200 linear feet, located on the rear exterior garage door.

• Interior board sheeting at 30% Chrysotile, approximately 18,800 square feet, located on the interior walls and ceiling.

• 10” pipe insulation at 40% (gray) and 10% (white) Chrysotile, and 20% (white) Amosite, approximately 250 linear feet, located throughout the 10” pipes and elbows on the hot water piping.

• 4” pipe insulation at 40% (off-white) Chrysotile, approximately 500 linear feet, located throughout the 4” pipes and elbows.

Any thermal or mechanical materials housed within wall cavities or mechanical piping / ductwork, valve packing materials, gasketing materials, fire doors, roofing materials, and materials behind utility panels could not be sampled without destruction, inaccessibility, or safety concerns. These materials were visually assessed and presumed to be asbestos-containing materials. Care must be taken when gaining access to these areas during renovation or demolition activities. Where suspect asbestos-containing materials are discovered, a survey will be required.

LBP testing that conforms to the Federal Housing and Urban Development (HUD) Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing was completed on painted surfaces on the interior and exterior of the building. No paint chip samples were taken. A total of 63 tests (assays) were taken on surfaces inside of the building using an X-ray fluorescence analyzer. Lead concentrations that meet or exceed the HUD published levels identified as being potentially dangerous (e. g., greater than or equal to 1.0 milligrams per centimeter square (> 1.0 mg/cm2) were encountered on 17 surfaces:

Sampled materials that tested positive for lead-based paint:

• Cream-colored paint on the exterior window sashes

• Light green and dark green paint on the upper and lower walls of the main room

• Light green on a wall in the hallway

• Blue paint on the walls in the restroom

• Green paint on the door casing and jamb in the main equipment room

• Green paint on the window sashes and aprons in the main equipment room

The Occupational Safety and Health Administration (OSHA) regulates workers’ exposure to lead paint concentrations in any amount. Therefore, in order to satisfy OSHA requirements, worker protection and monitoring may be required for work activities that disturb paints that contain lead, regardless of the amount. It is the responsibility of the contractor to conduct the work in accordance with the OSHA Construction Standard for Lead (29 CFR 1926.62).

1.0 INTRODUCTION

Jacobs Engineering Group, Inc. (Jacobs) retained Sci-Tek Consultants, Inc. (Sci-Tek) to conduct asbestos and lead-containing paint surveys of the of the Naval Support Activity, Building 608B, Locomotive and Train Shed located in Mechanicsburg, Pennsylvania. The scope of the surveys was limited to Sci-Tek’s investigation and sampling of suspect Asbestos Containing Materials (ACMs) and lead-containing paints. The asbestos and lead paint survey was performed on November 13, 2017 by Pennsylvania Licensed Asbestos Building Inspector / Management Planner / Project Designer (PA ID #030760) and Lead-Based Paint (LBP) Inspector / Risk Assessor (PA ID #002454) Paula South, and Pennsylvania Licensed Asbestos Building Inspector / Management Planner (PA ID #054656) and Lead-Based Paint (LBP) Inspector / Risk Assessor (PA ID #057037) Eric Bordenick. David Wilcots, P.G. provided administrative management and quality assurance reviews for the project, and Paula South served as Project Manager for Sci- Tek.

1.1 Asbestos Survey

Suspect ACM materials that were sampled and laboratory tested included interior and exterior board sheeting, window caulking, door caulking, cove base, floor tile, mastics, sheetrock, and pipe insulation. Suspect material samples were containerized, labeled, and delivered to International Asbestos Testing Laboratories (iATL) for polarized light microscopy (PLM) analysis. iATL is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) for analysis of asbestos bulk samples (NVLAP #101165-0). Positive ACM materials that were sampled and tested included interior and exterior board sheeting, window and door caulking / glazing, and 4” and 10” pipe insulation.

When asbestos samples analyzed by PLM yield results between 1 and 10 percent asbestos, it is common practice to verify the low-percentage samples through the use of point counting, in order to provide higher accuracy. Point Counting is approved by the U.S. Environmental Protection Agency (EPA) for confirmation of low concentrations of asbestos in bulk building materials. Point counting was automatically performed by the laboratory on any PLM samples falling under 10% asbestos.

A summary table of all sample materials that have been identified as Asbestos Containing Materials (>1% asbestos minerals) and non-ACM for bulk analyses is presented in Appendix A. This table also illustrates the ACM location, estimated quantity, and condition of each type of material. The ACM identified in this report is categorized as friable material (able to be crushed into powder with hand pressure) and non-friable material, with variable material conditions at the time of the inspection. Appendix B of this report contains the summary table for positive ACM. Appendix C of this report contains laboratory reports of the ACM Analytical Results.

1.2 Visual Observations

The asbestos survey focused on the 608B building and surrounding areas on the property. The square footage of observed materials was estimated based on onsite calculations by Sci-Tek.

Presumed materials include any thermal or mechanical materials housed within wall cavities or mechanical piping / ductwork, valve packing materials, gasketing materials, wiring beneath metal sheathing, vibration dampeners, and materials behind electrical panels. These materials could not be sampled due to inaccessibility, destruction concerns, or safety concerns, and were presumed to be asbestos-containing materials.

1.3 Lead-Based Paint (LBP) Survey

Lead in paint sampling was performed utilizing an RMD Brand, Model LPA-1 (Lead Paint Analyzer), X-Ray Fluorescence Type, direct reading/data-logging instrument (Serial Number 2528). The RMD XRF takes direct LBP samples without damaging the existing condition of the paint. Sample results are electronically stored and downloaded into a spreadsheet format.

A comprehensive list of all samples taken is listed on the “Lead-Based Paint Complete XRF Sample Results” located in Appendix E.

After reviewing the sample data, positive LBP samples were compiled into a second chart.

This chart contains samples that indicated a sample lead content of 1.0 mg/cm2 and greater.

According to the U.S. Department of Housing and Urban Development, any paint containing a lead content of 1.0 mg/cm2 (or 0.5 percent by weight) or greater is considered LBP1.

Positive LBP sample results are listed for each building constituent on the “Lead Based Paint Positive Sample Results Sheet” located in Appendix D.

This survey has found that lead-based paint, as per the EPA definition, was detected in 17 locations, including exterior window sashes, main room walls, a hallway wall, restroom walls, and the main equipment room door and window frames.

1 Department of Housing and Urban Development 24 CFR Part 35 Section C “Definitions”

2.0 SAMPLE METHODOLOGY

2.1 Asbestos Field Sampling Identification

Suspect ACM was categorized into homogeneous areas based on similarity in visual appearance, texture and assumed age. The suspect materials were then listed as friable or non-friable forms of ACM. Friable ACM is any material that can be crushed, pulverized, or reduced to a powder by hand pressure. Non-friable ACM is usually bonded with another substrate and is less likely to become airborne. While a material can be characterized as non-friable ACM, it has the potential to become a friable ACM if severely damaged or disturbed.

The EPA further distinguishes three (3) categories of ACM used in buildings as:

Surfacing Materials, which are sprayed or troweled-on surfaces for acoustical, decorative, or fireproofing purposes (largely friable).

Thermal System Insulation, which is insulation, used on hot and cold water systems and heating, ventilation, and air conditioning (HVAC) systems (largely friable).

Miscellaneous Materials, which are other products and materials such as floor tiles, mastic, caulking, etc. (largely non-friable).

The material bulk samples were collected, placed in resealable bags, labeled, and submitted to a National Voluntary Laboratory Accreditation Program (NVLAP)-accredited laboratory.

2.2 Asbestos Field Documentation

All field observations and laboratory analysis results are summarized in the Asbestos Sample Summary Table (Appendix A). This table provides details on the following parameters:

1. Sampling Frequency – Sampling frequency was based on 40 CFR Part 763

Subpart E, Asbestos Hazard Emergency Reduction Act (AHERA) Protocols.

Random samples were collected from each homogeneous area. The samples collected for this survey were classified as miscellaneous and thermal system insulation materials.

2. Material Location – Location of homogeneous material being inspected.

3. Sample Description – Brief description of the material inspected.

4. Sample Number – A unique sample identification number was assigned by the inspection team to each asbestos bulk sample taken during this survey.

5. Sample Results – Percent and type of asbestos identified by the analytical laboratory for all positive ACM samples (a material is considered positive for asbestos at 1% or greater under PLM and Point Counting). The six types of asbestos minerals are:

Ch = Chrysotile Tr = Tremolite Am = Amosite Ac = Actinolite An = Anthophyllite Cr = Crocidolite

The entry “ND” in a column means None Detected by the laboratory.

6. Quantity – Is defined as linear footage (LF), square footage (SF), or number of each material contained in a room (EA), (N/A) is non-applicable.

7. Condition – Overall condition assessment that is grouped into one of the three following categories:

• Good - The material is well-bonded to an underlying structure. For example, if piping material did not contain breaks, tears, etc. The material is not water damaged and has no exposed surface area.

• Fair - The material is bonded to an underlying structure. For example, if piping material contained some breaks or tears in its covering. Exposed surface area is minimal.

• Poor - The material is not well-bonded to an underlying structure. For example, if piping material is not totally covering the insulation and there are many breaks, tears, etc. The material has some fiber release potential, some water damage, and the amount of surface area exposed is greater than 25%.

8. Friability – A material is considered friable if, when dry, it may be crumbled, pulverized, or reduced to powder by hand pressure.

9. Potential for Disturbance – Potential for material to be damaged based on location, condition, and material type and accessibility. Potential for disturbance is ranked into one of three categories:

• High - The material is readily accessible to the occupants of the building.

• Med - The material is not so readily accessible to building occupants or is only accessible to custodial and maintenance personnel: boiler rooms, storage areas, mechanical rooms, etc.

• Low - The material is not easily accessible to building occupants: tunnels, crawlspaces, plumbing access areas, etc.

2.3 Lead-Based Paint Field Documentation

Sample identification is a key component in the LBP Inspection. Consistent location and identification procedures allow others to readily find specific painted surfaces that were sampled. Sample location and identification methodology is performed as follows:

• All sides of a room being sampled are labeled A, B, C, or D.

• The assignment of the letters depends on the orientation of the wall that is located closest to the main road of the unit’s address.

• Standing in the middle of the room, the wall closest to the main road is labeled as

“Wall A”.

• Going in a clockwise motion, each wall is then labeled in order B, C, and D.

• Features on each wall are labeled by name. Examples: Window Sill, Window Apron, Window Sash, Door Jamb, Baseboard, etc.

• A door or window can have multiple locations along the same wall. Specific locations are designated by L, C, and R (Left, Center, and Right).

2.4 Laboratory Testing Information

Bulk ACM samples were analyzed by International Asbestos Testing Laboratories (iATL) using PLM methods to detect asbestos fibers and distinguish between the following asbestos types: actinolite, amosite, anthophyllite, chrysotile, crocidolite, and tremolite. Samples were analyzed using EPA Method EPA 600/R-93/116. Results were reported as estimates of percent by weight. iATL International is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) for analysis of asbestos bulk samples (NVLAP #101165-0).

When asbestos samples that are analyzed by PLM yield results between 1 and 10 percent asbestos, it is common practice to verify the low-percentage samples through the use of Point Counting, in order to provide better accuracy than direct PLM analysis. Point

Counting is approved by the Environmental Protection Agency for confirmation of low concentrations of asbestos in bulk building materials. Point counting was automatically performed by the laboratory on any PLM samples falling below 10% asbestos.

3.0 ANALYTICAL RESULTS

3.1 Asbestos Analytical Results

The laboratory analytical results revealed that asbestos containing materials were detected in the following materials:

• Exterior board sheeting at 20% Chrysotile, approximately 13,000 square feet, located on the exterior siding and soffit.

This survey has found that lead-based paint, as per the EPA definition, was detected on the following painted surfaces:

• Cream-colored paint on the exterior window sashes

• Light green and dark green paint on the upper and lower walls of the main room

• Light green on a wall in the hallway

• Blue paint on the walls in the restroom

4.0 REGULATORY REVIEW

U.S. Environmental Protection Agency (EPA), National Emissions Standards for Hazardous Air Pollutants (NESHAP), 40 CFR 61, Subpart 1.

NESHAP regulates application and removal and disposal of ACM, as well as the waste shipment records for tracking ACM. The NESHAP requires friable ACM or non-friable ACM that may become friable during renovation or demolition work to be appropriately removed. The NESHAP also requires a ten (10) day written notification prior to building demolition or renovation where projects involve quantities of ACM that are greater than 260 linear feet or 160 square feet. NESHAP has been incorporated by reference into the PA Code, Title 25 Environmental Protection. Under the code, the Pennsylvania Department of Environmental Protection (PADEP) requires notification of any impending asbestos abatement projects.

Occupational Safety and Health Administration (OSHA) Asbestos Standards, 29 CFR 1926-1101 and

29 CFR 1910-1001.

The OSHA Asbestos Standards apply to workers who have potential exposures to asbestos in the workplace. The General Industry Standard (1910.1001) describes the steps an employer must take to reduce exposures in the workplace. The construction industry standard describes safe practices for employees engaged in demolition and construction projects which may contain ACM and the following related activities likely to involve asbestos exposure: removal, encapsulation, alteration, repair, maintenance, insulation, spill/emergency clean-up, transportation, and disposal and storage of

ACM.

OSHA has established a Permissible Exposure Limit (PEL) of 0.1 fiber per cubic centimeter (f/cc) measured over an 8-hour time-weighted average (TWA), and a Short Term Excursion Limit (STEL) of 1.0 f/cc measured over a 30-minute time frame. Any construction work involving ACM, regardless of exposure levels, minimally requires an exposure assessment, worker training, a “competent person” for supervision, mandatory work practices, engineering controls and record keeping. Workers in “Regulated Areas” in excess of the PEL must be part of a medical surveillance program and wear respiratory protection in accordance with the Respirator Standard (29 CFR 1910.134), hazards shall be communicated to workers.

Commonwealth Of Pennsylvania, Department Of Labor and Industry (PADLI), Act of 1990, P.L.

805, No. 194 – Asbestos Occupations Accreditation and Certification Act

Notification must be given to the PA Department of Labor and Industry and any other regional, state, and local authority having jurisdiction prior to the start of the project. All required permits must be secured for the work, including disposal of asbestos in an approved landfill, as well as any required permits. The Contractor will provide the PADLI with all necessary information for the securing of the permit, and will follow all instructions and requirements of the PADLI in performing the work, including but not limited to asbestos removal and transport and disposal of asbestos containing waste.

U. S. Department of Housing and Urban Development (HUD) Title 24 CFR, Part 35 – Lead Based Paint Poisoning Prevention in Certain Residential Structures

US Department of Housing and Urban Development has established specific guidelines and procedures for Lead Based Paint inspections. The inspection protocol in Chapter 7 of HUD Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing (2012 revision) was utilized for the assessment covered in this report.

U.S. Environmental Protection Agency (EPA), Title 40 CFR, Chapter I, Part 745 – Lead-Based Paint Poisoning Prevention in Certain Residential Structures

Both the US EPA and the US Department of Housing and Urban Development define a Lead Based Paint inspection as a surface-by-surface investigation to determine the presence of Lead Based Paint. The latest 2001 Amendment to Part 745 includes definitions of Paint-lead hazards, Dust-lead hazards, and Soil-lead hazards applicable to target housing and child-occupied facilities.

Occupational Safety and Health Administration (OSHA), 29 CFR 1926.62 – Lead Exposure in Construction Rule

Employers subject to this standard are responsible for having a worker protection program. The PEL limits worker exposures to 50 micrograms of lead per cubic meter of air, averaged over an 8-hour workday. The action level of 30 micrograms of lead per cubic meter of air triggers certain compliance activities such as personal air monitoring and medical surveillance.

Commonwealth Of Pennsylvania, Department Of Labor and Industry, PA Title 34, Chapter 203

– Lead-Based Paint Occupation Accreditation And Certification

These regulations, effective in November of 1997, include general administrative requirements, certification procedures, enforcement procedures and penalties, and other pertinent information involving lead-based paint activities. Licensed personnel shall perform Lead Based Paint abatement, inspections and risk assessments.

5.0 RECOMMENDATIONS

5.1 Recommendations regarding asbestos containing materials

This survey has found that asbestos-containing material was detected in the following materials:

• Exterior board sheeting at 20% Chrysotile, approximately 13,000 square feet, located on the exterior siding and soffit.

• Exterior window caulking at 4.4% and 4.7% Chrysotile, approximately 2,000 linear feet, located on the exterior windows.

• Exterior door caulking at 4.6%, 1.4%, and 5.3% Chrysotile, approximately 100 linear feet, located on the front exterior garage door.

• Exterior door glazing at 5.6% and 5.1% Chrysotile, approximately 200 linear feet, located on the rear exterior garage door.

• Interior board sheeting at 30% Chrysotile, approximately 18,800 square feet, located on the interior walls and ceiling.

• 10” pipe insulation at 40% (gray) and 10% (white) Chrysotile, and 20% (white) Amosite, approximately 250 linear feet, located throughout the 10” pipes and elbows on the hot water piping.

The following recommendations are based on the data obtained at the sample locations, laboratory test results, and our observations during the survey.

It is recommended that all positive asbestos-containing material be abated according to federal, state, and local regulations by licensed abatement workers. A licensed asbestos abatement contractor shall be utilized to perform the abatement activities. A licensed project designer shall be utilized to prepare technical specifications for the abatement of ACM. Area air monitoring should be performed during the abatement of ACM and clearance sampling shall be conducted to ensure the integrity of the ACM removal work.

5.2 Recommendations regarding lead-based paint

This survey has found that lead-based paint, as per the EPA definition, was detected on the following painted surfaces:

• Cream-colored paint on the exterior window sashes

• Light green and dark green paint on the upper and lower walls of the main room

• Light green on a wall in the hallway

• Blue paint on the walls in the restroom

The following recommendations are based on the data obtained at the sample locations, test results, and on our observations during the survey:

Employers subject to OSHA Lead Exposure in Construction rule (29 CFR 1926.62) are responsible for having a worker protection program. Maximum limits of exposure to lead are set by the permissible exposure limit (PEL) and the action level. The permissible exposure limit limits worker exposures to 50 micrograms of lead per cubic meter of air, averaged over an 8-hour workday. The action level of 30 micrograms of lead per cubic meter of air triggers certain compliance activities such as personal air monitoring and medical surveillance. It is noted that this recommendation applies to all levels of lead content.

At a minimum, a worker protection program for employees exposed to lead should include:

• Hazard determination, including exposure assessment

• Engineering and work practice controls

• Protective clothing and equipment

• Respiratory protection

• Housekeeping

• Hygiene facilities and practices

• Medical surveillance and provisions for medical removal

• Training

• Signs

• Recordkeeping

The worker protection program should be written and overseen by a competent person -one who has specific training in lead hazards and who has the authority to take corrective measures when necessary.

7.0 REPORT LIMITATIONS

Sci-Tek Consultants, Inc. holds that services performed for this survey were conducted in a manner consistent with that level of care and skill ordinarily exercised by members of the profession practicing contemporaneously in the same locality under similar conditions. Sci-Tek used commercially reasonable efforts consistent with local industry standards in place at the time of the survey to identify the suspect hazardous materials found and prepared this report based on the data obtained. Representatives of Jacobs Engineering Group, Inc. and the NAVFAC identified the areas that will be impacted to Sci-Tek representatives, and this report is limited to those areas.

There is a risk that some materials at the site contain ACM, which were not identified during the survey. This is unavoidable because ACM has been used in a wide variety of building materials and it is difficult to distinguish materials based on visual observations. In addition, without a complete and accurate record of repair and remodeling work that has taken place during the building’s history, it is difficult, if not impossible, to visually identify, sample, and test all materials that may be present at the time of the survey. This is especially true in older buildings, which have been repaired and remodeled multiple times with different materials from different sources over the years.

Sci-Tek Consultants, Inc. cannot and will not warrant that the Assessment that was requested by the client will satisfy the dictates of, or provide a legal defense in connection with, any environmental laws or regulations. It is the responsibility of the client to know and abide by all applicable laws, regulations, and standards, including EPA’s Renovation, Repair and Painting regulation.

The results reported and conclusions reached by Sci-Tek Consultants, Inc. are solely for the benefit of the client. The results and opinions in this report, based solely upon the conditions found on the property as of the date of the Assessment, will be valid only as of the date of the Assessment. Sci-Tek Consultants, Inc. assumes no obligation to advise the Client of any changes in any real or potential lead hazards at this location that may or may not be later brought to our attention. Further conditions and limitations to this contracted report are included in the general terms and conditions supplied to the Client with the contract for services.

Information Pertinent to this Report:

Analysis by US EPA 600 93-116: Determination of Asbestos in Bulk Building Materials by Polarized Light Microscopy (PLM).

Certifications:

NIST-NVLAP No. 101165-0• NY-DOH No. 11021• AIHA-LAP, LLC No. 100188•

Quantification at <0.25% by volume is possible with this method. (PC) Indicates Stratified Point Count Method performed. (PC-Trace) means that asbestos was detected but is not quantifiable under the Point Counting regimen. Analysis includes all distinct separable layers in accordance with EPA 600 Method. If not reported or otherwise noted, layer is either not present or the client has specifically requested that it not be analyzed (ex. analyze until positive instructions). Small asbestos fibers may be missed by PLM due to resolution limitations of the optical microscope.
