EXECUTIVE SUMMARY

The subject property is improved with the Buildings HP135, HP 136, and SHP135A located at Marine Corps Base (MCB) Camp Lejeune in Jacksonville, North Carolina. The three-story Bachelor's Enlisted Quarters (BEQ) Building HP135 consists of individual living quarters, common areas, laundry rooms, and mechanical chases. The building is serviced by HP136, a stand-alone mechanical building with similar construction. SHP135A is a covered gazebo purposed for outdoor grilling and recreation. The structures are currently in use and are slated for demolition.

The purpose of the survey was to determine if asbestos-containing materials (ACMs) and lead-containing paint (LCP) are present on the subject property. The survey was performed within the interior and exterior areas of the subject buildings as well as the roof.

Asbestos Survey

On April17, 2024, Mr. Braxton B. Dawson, a North Carolina accredited asbestos inspector, performed the asbestos assessment. Bulk samples were submitted to Scientific Analytical Institute, Inc. (SAI) in Greensboro, North Carolina for analysis via Polarized Light Microscopy (PLM) in accordance with the current EPA-600 methodology.

A total of 46 bulk samples from 18 homogeneous areas were submitted to the laboratory of which 48 layers were analyzed. Based on the laboratory analysis of the bulk samples collected during the survey, some of the materials were reported to contain asbestos above the regulatory limit of 1%.

The following materials were reported to be asbestos-containing:

• Built-up roofing material in attic, 14,000 square feet;

• Perimeter flashing material, 1,200 square feet.

Due to inaccessibility or the destructive means that asbestos sampling requires, unseen ACMs may remain within the building hidden behind inaccessible areas that include, but are not limited to, sub-grade walls, structural members, topping slabs, sub-grade sealants, flooring located below underlayments, areas behind exterior walls, pipe trenches, and subsurface utilities, etc.

If suspect materials are discovered during construction activities, they should be presumed to contain asbestos and be treated as ACMs or be sampled immediately upon discovery and prior to disturbance for asbestos content by an accredited or certified asbestos inspector in accordance with 29 Code of Federal Regulations (CFR) 1926.1101.

Lead Paint Survey

The lead paint assessment was conducted by collection of paint chip samples from suspect lead paint materials. The paint chip samples were submitted to a laboratory that participates in the American Industrial Hygiene Association (AIHA) Environmental Lead Proficiency Analytical Testing (ELPAT) Programs for analysis of lead concentration (percent by weight) using Flame Atomic Absorption Spectroscopy.

ii

Based on the laboratory analysis of the paint chips collected during the survey, the following building components were reported as lead-containing paint:

• White/beige metal doors in the common areas;

• Brown metal doors and frames on the exterior of the building;

• Beige CMU walls inside the living quarters; and

• Beige metal doors inside the living quarters.

Paint and surface coatings that contain detectable concentrations of lead are considered “lead-containing paints”. Since OSHA has no specific action level for lead in paint, all paint on the site found to have a measurable concentration of lead should be assumed to be lead-containing. Work performed that may disturb lead-containing paint is regulated under OSHA as referenced under 29

CFR 1926.62.

Recommendations regarding the removal and disposal of the ACM and LCP identified by ECS can be found in Section 5.0 of this report.

The executive summary is an integral portion of this report, however, ECS recommends the report be read in its entirety.

1.0 SITE DESCRIPTION

The subject property is improved with Buildings HP135, HP 136, and SHP135A located at Marine Corps Base (MCB) Camp Lejeune in Jacksonville, North Carolina. The three-story Bachelor's Enlisted Quarters (BEQ) Building HP 135 consists of individual living quarters, common areas, laundry rooms, and mechanical chases. The building is serviced by HP136, a stand-alone mechanical building with similar construction. SHP135A is a covered gazebo purposed for outdoor grilling and recreation. The structures are currently in use and are slated for demolition.

HP135 building construction includes concrete and masonry unit (CMU) walls with brick veneer façade, concrete plank decking, and a wood-framed shingle roof system. The original built-up roofing system is still intact and is located in the attic. The exteriors consist of a brick veneer façade with areas of concrete finishes. Interior finishes include CMU walls, vinyl composite floor tiles (VCT), acoustical ceiling texture, and concrete floor coatings. Mechanical and plumbing systems were observed to be insulated with fiberglass or foam insulations. SHP135A building construction includes a wood-framed shingle roof supported by wood posts on a concrete slab foundation.

2.0 PURPOSE

The purpose of the Asbestos and Lead Paint Assessment was to identify asbestos-containing materials (ACM), lead-containing paint (LCP) which require special handling and/or disposal if disturbed during demolition activities. The identification of ACMs require trained labor, regulated work practices, and special disposal. The identification of LCP or other lead hazards requires disclosure to contractors and monitoring of lead exposure.

3.0 METHODOLOGY

ECS performed the authorized Scope of Services in general accordance with our proposal, standard industry practice(s) and methods specified by regulation(s) for the identification of ACMs and LBPs.

3.1 Asbestos-Containing Materials

The asbestos survey was performed by Mr. Braxton B. Dawson (NC Asbestos Inspector No. 12830) on April17, 2024. The survey consisted of observing the accessible areas of Building HP135, HP 136, and SHP135A for the presence of suspect materials which may contain asbestos. The survey involved detecting both friable materials (materials which can be pulverized or reduced to a powder by hand pressure when dry) and non-friable materials (materials which pose a hazard when sawn, sanded, drilled or pulverized). Homogeneous materials (based on material type, color, texture, etc.) were identified in during the survey.

The EPA National Emissions Standard for Hazardous Air Pollutants (NESHAP) requires a survey for asbestos prior to renovation or demolition. Demolition is defined under NESHAP as the removal of a load-bearing structural member and renovation is an action which disturbs building materials. On the basis of requirements under NESHAP and North Carolina Asbestos Hazard Management Program (AHMP), administered by the Health Hazards Control Unit (HHCU), for renovation or demolition activities, ECS conducted a limited survey for potential ACM. The ACM survey was limited in that we did not conduct demolition such as jack/sledgehammering to expose potentially concealed materials.

May 1, 2024

ECS Project # 49:22727

Samples were collected in general accordance with Environmental Protection Agency (EPA) Standard 40 CFR 763 Subpart E, Asbestos Hazard Emergency Response Act (AHERA) and Occupational Safety and Health Administration (OSHA) Standard 29 CFR 1926.1101 Inspection Protocol.

In order to determine if the suspect materials observed during the visual survey contained asbestos, representative bulk samples were collected and placed in sealed packages. Samples were collected during the survey and submitted to SAI for analysis using the Environmental Protection Agency (EPA) recommended method of Polarized Light Microscopy (PLM) coupled with dispersion staining (Method No. EPA 600/R-93/116). SAI participates in the National Voluntary Laboratory Accreditation Program (NVLAP). Their NVLAP accreditation number is 200664-0. Several of the samples were layered and analyzed as multiple samples. EPA regulations require that multiple samples of each homogeneous area be collected for laboratory analysis. The material type, sample location, and analytical results of each bulk sample are also summarized in the attached Asbestos Bulk Analysis report in Appendices.

Samples were analyzed using “Positive Stop” methodology. If one sample of a homogeneous material is reported to contain asbestos, the remaining samples of that material are not analyzed. If one sample of a material from a homogeneous area is reported to contain greater than 1% asbestos, then by EPA definition, it is characterized as an ACM regardless of additional analysis.

During the survey, ECS attempted to identify suspect ACMs in readily accessible areas. However, due to the destructive means required to identify some materials, certain areas were deemed inaccessible (i.e. behind walls or sub grade materials) and were not surveyed for suspect ACMs.

3.2 Lead in Paint and Surface Coatings

ECS completed a lead paint screening within the building as part of our assessment activities. The collection of representative paint chip samples was performed throughout the buildings. Samples collected were containerized, labeled, and transported to SAI. Each of the paint chip samples were subsequently analyzed for the presence of lead reported in percent lead by weight via EPA Method SW 846, 7000B (Flame AAS). The chain-of-custody, which includes sample numbers and sample locations, is included in an Appendix of this report.

4.0 RESULTS

The following is a summary of laboratory results, findings and observations.

4.1 Asbestos Sampling

In total, 46 bulk samples from 18 homogeneous areas were submitted to the laboratory of which 48 layers were analyzed.

An ACM is defined as any material containing more than one percent (>1%) asbestos as determined using the method specified in Appendix E, Subpart E, 40 CFR Part 763, Section 1, PLM. Materials are categorized by the U.S. EPA in the following categories:

• Friable ACMs are defined as any ACM that, when dry, can be crumbled, pulverized or reduced to powder by hand pressure. Non-friable ACMs are defined as any ACM that, when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure.

May 1, 2024

• Category I non-friable ACM are listed as following: packings, gaskets, resilient floor coverings, and asphalt roofing products containing more than one percent (>1%) asbestos.

• Category II non-friable ACM are listed as any material, excluding Category I non-friable ACM, containing more than one percent (>1%) asbestos.

Regulated Asbestos Containing Materials (RACM) are friable ACM or non-friable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading or has crumbled, been pulverized, or reduced to powder in the course of renovation and/or demolition operations.

SAI submitted a signed final laboratory report to ECS on April24, 2024. Several of the bulk samples submitted for analysis were reported to contain asbestos in detectable concentrations. A complete list of the sampled materials submitted for analysis and material locations are included in the table below. Sample location figures and photographs are located in Appendix I and II of this report.

The above provided approximate quantities of the identified ACMs are for informational purposes only and should not be used for bidding purposes. ECS does not warranty or guarantee the estimated quantities provided. The contractors bidding on asbestos abatement work should visit the site prior to bidding to field verify the estimated quantities of ACMs and become familiar with the site conditions and address any technical or engineering

May 1, 2024 considerations with respect to asbestos removal in their bids or estimates. Any similar materials located on the property should also be assumed to contain asbestos unless tested and the laboratory analysis indicates that asbestos is not present.

4.2 Suspect or Assumed Asbestos-Containing Materials

Due to the inaccessibility or the destructive means that asbestos sampling requires, additional suspect ACMs may remain within the building hidden behind inaccessible areas that include, but are not limited to, sub-grade walls, structural members, topping slabs, sub-grade sealants, flooring located below underlayments, areas behind exterior walls, pipe trenches, and subsurface utilities, etc.

These areas were deemed inaccessible and were not assessed.

If these materials are discovered during construction activities, they should be presumed to contain asbestos and be treated as ACMs or be sampled immediately upon discovery and prior to disturbance for asbestos content by a certified asbestos inspector in accordance with 29 CFR 1926.1101.

4.3 Lead in Paint and Surface Coatings

Paint and surface coatings which contain detectable concentrations of lead considered “lead-containing paints” (LCP). Since OSHA has no specific action level for lead in paint, all paint on the site found to have a measurable concentration of lead should be assumed to be lead containing.

Work performed which may disturb lead-containing paint is regulated under OSHA as referenced under 29 CFR 1926.62.

Lead was detected in the paint chip samples analyzed. Lead-containing paints identified are summarized in the table below and photographs are located in the Appendix.

5.0 RECOMMENDATIONS AND REGULATORY REQUIREMENTS

Based on our understanding of the purpose of the Asbestos and Lead Paint Assessment, the results of laboratory analysis, and our findings and observations, ECS presents the following recommendations.

5.1 Asbestos-Containing Materials

ECS recommends where a material type has been identified as asbestos-containing that other materials with similar color, texture, age, and size throughout the building’s interior and exterior be assumed to contain asbestos. Please refer to Section 4.1 for a complete list of building materials that were reported positive for asbestos and to Section 4.2 for materials that were assumed to contain asbestos. Identified ACMs should be removed, encapsulated, or enclosed prior to disturbance of the materials.

May 1, 2024

If ACMs are to be removed, an accredited asbestos abatement contractor should perform the removal. it is recommended that an industrial hygienist monitor the project. This involves collecting air samples from within and outside abatement work areas to monitor the asbestos abatement contractor’s work practices over the course of the project. The industrial hygienist should evaluate if the asbestos abatement work is in accordance with project specifications, U.S. EPA regulation 40 CFR Part 61-NESHAP Subpart M: National Emission Standard for Asbestos, and OSHA regulation 29 CFR 1926.1101 – Asbestos in Construction. The industrial hygienist should assess each work area to monitor the removal of ACMs. Only after the industrial hygienist has determined the identified ACMs have been removed should final clearance air samples be collected (if necessary).

Suspect ACMs not observed due to inaccessibility or not sampled due to the destructive means that sampling would require may also be encountered during construction activities. At the time of the survey, only limited destructive means were used to locate or sample suspect ACMs; therefore, additional suspect ACMs may remain within inaccessible areas that include, but are not limited to, sub-grade walls, structural members, topping slabs, exterior areas, sub-grade sealants, flooring located below underlayments, vapor barriers, pipe trenches, and other subsurface utilities, etc. If additional suspect ACMs are uncovered which were not accessible during this survey, it is recommended that these materials either be assumed to contain asbestos or be sampled prior to disturbance upon discovery for asbestos content by an asbestos inspector in accordance with 29 CFR 1926.1101.

5.2 Lead in Paint and Surface Coatings

Based on the findings of the lead survey, detectable concentrations of lead were identified on some paints and surface coatings.

The presence of lead is a concern primarily when conditions exist where it may be inhaled or ingested.

Regardless of the analytical results of a material, all painted and/or glazed surfaces may still contain concentrations of lead in the paint, which when disturbed, may generate lead dust greater than the Permissible Exposure Limit (PEL) of 50 micrograms per cubic meter (ug/m3) as an 8-hour Time Weighted Average (TWA) established by the OSHA “Lead Exposure in Construction Rule (29 CFR 1926.62).”

The OSHA standard gives no guidance on acceptable levels of lead in paint at which no exposure to airborne lead (above the action level) would be expected. Rather, OSHA defines airborne concentrations, and references specific types of work practices and operations from which a lead hazard may be generated (reference 29 CFR 1926.62, section d). Environmental and personnel monitoring should be conducted during any removal/demolition process (as appropriate) to verify that actual personal exposures are below the Permissible Exposure Limit (PEL) of 50 micrograms per cubic meter (µg/m3) as an 8-hour Time Weighted Average (TWA). Under OSHA requirements, the contractor performing renovation work will be required to conduct this monitoring and follow applicable requirements under 29 CFR 1926.62 if disturbing lead-containing paint.
