EXECUTIVE SUMMARY

The subject property is improved with Building TT-113 located at Iwo Jima Boulevard in Tarawa Terrace, Camp Lejeune, Onslow County, North Carolina. It is slated for interior and exterior renovations. The structure on the property is a single-story building utilized as the Tarawa Terrace II Child Development Center (CDC). The site features paved access from Iwo Jima Blvd, with a parking area to the north of the building. The building is currently occupied and is slated for interior and exterior renovations. ECS was contracted to perform an asbestos, lead paint, and mold assessment at the building prior to the proposed renovations.

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

Asbestos Survey

On August 30, 2024, Mr. Braxton B. Dawson, a North Carolina state-certified 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 twenty-three (23) bulk samples from eleven (11) homogeneous areas were submitted to the laboratory, of which thirty-one (31) layers were analyzed. Based on the laboratory analysis of the bulk samples collected during the survey, none of the materials were reported to contain asbestos.

Due to inaccessibility or the destructive means that asbestos sampling requires, unseen ACMs may remain within the building hidden behind inaccessible areas, which 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.

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.

Based on the laboratory analysis of the paint chips collected during the survey, lead was not detected above the laboratory detection limit.

ii

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.

Visible Mold Assessment

ECS did not observe evidence of visible mold or moisture during our assessment. However, it was reported that ceiling tiles had been replaced due to HVAC condensation as part of routine maintenance activities. ECS does not recommend additional assessment pertaining to mold at this time.

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 Building TT-113 located at Iwo Jima Boulevard in Tarawa Terrace, Camp Lejeune, Onslow County, North Carolina. It is slated for interior and exterior renovations. The structure on the property is a single-story building utilized as the Tarawa Terrace II Child Development Center (CDC). The site features paved access from Iwo Jima Blvd, with a parking area to the north of the building. The building is currently occupied and is slated for interior and exterior renovations. ECS was contracted to perform an asbestos, lead paint, and visible mold assessment in the building prior to the proposed renovations.

The building construction includes concrete masonry unit (CMU) walls with brick veneer façade, light-gauge steel framing, and a pitched standing seam metal roof system on a concrete slab foundation. Interior finishes include CMU walls, suspended ceiling tiles, gypsum upper ceilings, gypsum recessed skylights, aluminum framed windows, sheet vinyl flooring, and various styles of vinyl composite tiles (VCT).

2.0 PURPOSE

The purpose of the Asbestos, Lead Paint, and Mold Assessment was to identify asbestos-containing materials (ACM), lead-containing paint (LCP), and visible mold which may require special handling and/or disposal if disturbed during construction activities. The identification of ACMs requires 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.

3.1 Asbestos-Containing Materials

The asbestos survey was performed by Mr. Braxton B. Dawson (NC Asbestos Inspector No. 12830) on August 30, 2024. The survey consisted of observing the accessible areas of the building for the presence of suspect materials that may contain asbestos. The survey involved detecting both friable materials (materials that can be pulverized or reduced to a powder by hand pressure when dry) and non-friable materials (materials that pose a hazard when sawn, sanded, drilled, or pulverized).

Homogeneous materials (based on material type, color, texture, etc.) were identified during the survey.

The EPA National Emissions Standard for Hazardous Air Pollutants (NESHAP) requires a survey for asbestos before renovation or demolition. Demolition is defined under NESHAP as the removal of a load-bearing structural member, and renovation is an action that disturbs building materials. Based on 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. Samples were

September 24, 2024

ECS Project # 49:23942 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.

Representative bulk samples were collected, placed in sealed packages, 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 collecting multiple samples of each homogeneous area 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 the “Positive Stop” methodology. If one sample of a homogeneous material is reported to contain asbestos, the remaining samples 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 interior and exterior of the building. 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.

3.3 Visible Mold

The assessment included a non-invasive visual and olfactory survey for evidence of mold and moisture within the subject property. The assessment focused on the areas of the building to be renovated. The ECS site personnel observed readily accessible areas and selected building materials to evaluate visible suspect fungal growth and/or moisture-impacted materials. A reasonable effort was made to identify water and mold-impacted areas; however, this does not imply a guarantee that all possible reservoirs of mold were identified because mold or water-impacted building materials may be hidden by walls, flooring, partitions, etc.

As is the case with many assessments of this nature, this evaluation was limited to the areas of the property deemed reasonably accessible by ECS. Reasonable effort was made to identify mold and moisture-impacted areas. However, mold/moisture-impacted areas may remain unidentified.

4.0 RESULTS

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

September 24, 2024

4.1 Asbestos Sampling

A total of twenty-three (23) bulk samples from eleven (11) homogeneous areas were submitted to the laboratory, of which thirty-one (31) 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.

• Category I non-friable ACMs include 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 September 11, 2024. None 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 below. Sample locations can be found in Appendix I and photographs are located in Appendix II.

Analytical results of each material are also summarized in the attached Asbestos Bulk Analysis report in Appendix III.

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.

Based on laboratory analysis of the paint chip samples collected and analyzed for lead content, lead was not detected above the method detection limit.

5.0 RECOMMENDATIONS AND REGULATORY REQUIREMENTS

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

5.1 Asbestos-Containing Materials

None of the bulk samples submitted to Scientific Analytical Institute, Inc. were reported to contain detectable concentrations of asbestos. If additional suspect asbestos-containing materials are uncovered which were not accessible during this sampling event, it is recommended that these materials be sampled or tested immediately 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 results of paint chip sampling, lead was not detected in the samples above the laboratory detection limit.

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.

5.3 Mold and Moisture

ECS did not observe evidence of visible mold or moisture during our assessment. However, it was reported that ceiling tiles had been replaced due to HVAC condensation as part of routine maintenance activities. ECS does not recommend additional assessment pertaining to mold at this time.

Note: The purpose of this survey was to evaluate areas where visible or apparent mold growth and/ or moisture intrusion has occurred and provide findings and recommendations for remedial work efforts. Identification and recommendation(s) for correction of all moisture intrusion concerns were outside of the scope of services for this work.
