EXECUTIVE SUMMARY

This executive summary is intended as an overview for the convenience of the reader. The report should be reviewed in its entirety prior to making any decisions regarding this site.

Terracon Consultants, Inc. (Terracon) conducted an asbestos and lead paint inspection for

Building 1103 located at MCAS in Beaufort, South Carolina. The purpose of this inspection was to sample and identify suspect asbestos-containing materials (ACM) and provide information regarding the identity, location, condition and approximate quantities of ACM in building components. In addition, limited paint sampling was performed on various painted components that may be impacted by construction activities within the structure to determine lead content.

The objective of the lead paint evaluation was to identify lead-containing paint systems on building components that may require special handling in accordance with the OSHA Lead in

Construction Standard.

Findings

Asbestos

Based on the results of laboratory analysis, none of the materials were confirmed to contain asbestos at concentrations greater than one percent (>1%).

Lead

Based on the results of laboratory analysis, two (2) paint chip samples were collected from the interior and exterior walls. The paint chip lead analyses were below the laboratory detection limits.

Recommendations

▪ Accumulation of Paint residue/waste (chips, dust, flakes, etc.) - Work involving any paint removal such as blasting or manual scraping may require laboratory testing by TCLP to characterize the waste stream and determine proper disposal requirements identified in SCDHEC solid waste regulations or any MCAS

Base Environmental requirements.

▪ If applicable to this project, a copy of this report must be submitted to SCDHEC at least ten (10) working days prior to demolition, which includes if load bearing walls will be impacted.

1.0 INTRODUCTION

Terracon Consultants, Inc. (Terracon) conducted an asbestos and lead inspection of Building

1103 located on the Marine Corps Air Station (MCAS) in Beaufort, South Carolina. The purpose of this survey was to sample and identify suspect asbestos-containing materials (ACM) and provide information regarding the identity, location, condition and approximate quantities of

ACM in interior building components. In addition, limited paint sampling was performed on various painted components of the structure.

The asbestos inspection was performed on November 9, 2023, by a South Carolina Department of Health and Environmental Control (SCDHEC) licensed asbestos inspector in general accordance with CEMS Project Plan dated July 23, 2023: Repair Building 1103 – BE2054M and the sampling protocols established in EPA 40 CFR 763 (Asbestos Hazard Emergency Response

Act, AHERA) and the SCDHEC Regulation 61-86.1 Standards of Performance for Asbestos

Projects.

2.0 BUILDING DESCRIPTION

Building 1103 is an approximately 1,100 SF structure located on the South end of runway 23-

05. It was constructed in 1986 and houses the Runway Approach Lighting Electrical Equipment and associated emergency generator. The building is constructed with CMU block walls and a steel roof decking ceiling. No other interior finishes are in place. The roof is constructed with a rubber membrane over plywood and steel support system. No roofing felt was observed. The building is unconditioned.

3.0 ASBESTOS SURVEY

The asbestos survey was conducted by SCDHEC licensed Asbestos Building Inspector Mr. Craig

C. Langford (License No. ASB-22775 Exp. 07/19/24). A copy of Mr. Langford’s license is included in Appendix D. The survey was conducted on November 9, 2023, in general accordance with the sampling protocols established by EPA Regulation 40 CFR 763 Subpart E 763.86, AHERA and SCDHEC R. 61-86.1. A summary of survey activities is provided below.

3.1 Historical Data and Reports

No previous asbestos survey reports were available or provided by the Client.

3.2 Regulatory Overview

NESHAP

Environmental Protection Agency (EPA) regulation 40 CFR 61, Subpart M, National Emission

Standards for Hazardous Air Pollutants (NESHAP), prohibits the release of asbestos fibers to the atmosphere during renovation/demolition activities. NESHAP requires that potentially regulated

Facilities | Environmental | Geotechnical | Materials 2 asbestos-containing building materials be identified, classified and quantified prior to planned disturbances or demolition activities. An ACM is defined as any material containing one or more of the six regulated forms of asbestos in an amount greater than one percent (1%). The asbestos NESHAP regulates asbestos fiber emissions and asbestos waste disposal practices.

Under NESHAP, asbestos-containing building materials are classified as either friable, Category

I non-friable or Category II non-friable ACM. Friable materials are those that when dry may be crumbled, pulverized or reduced to powder by hand pressure. Non-friable materials contain asbestos fibers which have been “locked in” by a bonding agent, coating, binder or other materials so that the asbestos is bound and will not readily release fibers during normal handling or use. Category I non-friable ACM includes packing materials, gaskets, resilient floor coverings, asphaltic roofing products and pliable mastics containing more than one percent asbestos. Category II non-friable ACM are non-friable materials other than Category I materials that contain more than 1% asbestos.

Friable ACM, Category I and Category II non-friable ACM which is in poor condition and has become friable or which will be subjected to drilling, sanding, grinding, cutting or abrading and which could be crushed or pulverized during anticipated renovation/demolition activities are considered regulated ACM (RACM). RACM must be removed prior to renovation or demolition activities.

State of South Carolina

In the state of South Carolina, asbestos activities are regulated by SCDHEC under the SCDHEC

Regulation 61-86.1 Standards of Performance for Asbestos Projects. SCDHEC require that any asbestos-related activity conducted in a public building be performed by personnel licensed by

SCDHEC. The owner or operator must provide SCDHEC with written notification of planned abatement and removal activities prior to the commencement of those activities. SCDHEC requires four-day notification for non-friable projects and 10-day notification for RACM projects.

Asbestos abatement must be performed by SCDHEC-licensed asbestos abatement contractors.

A SCDHEC-licensed Project Designer shall prepare a written abatement design for each abatement renovation project involving the removal of greater than 3,000 square, 1,500 linear, or 656 cubic feet of RACM. Third-party air monitoring must be conducted during the abatement of friable (regulated) ACM. The SCDHEC asbestos regulations can be found at https://scdhec.gov/environment/your-home/asbestos/asbestos-regulations.

SCDHEC defines a renovation as “altering a facility or one or more facility components in any way, including the stripping or removal of RACM from any facility component.” A demolition is defined as “wrecking or taking out any load-supporting structural member of a facility together with any related handling operations, the burning of any facility, or moving of a structure.”

OSHA

The Occupational Safety and Health Administration (OSHA) Asbestos Standard for Construction

Industry (29 CFR 1926.1101) regulates workplace exposure to asbestos. The OSHA standard requires that employee exposure to airborne asbestos fibers be maintained below 0.1 asbestos fibers per cubic centimeter of air (0.1 f/cc). The OSHA standard classifies construction and maintenance activities, which could disturb ACM, and specifies work practices and precautions https://scdhec.gov/environment/your-home/asbestos/asbestos-regulations

Facilities | Environmental | Geotechnical | Materials 3 which employers must follow when engaging in each class of regulated work. A full copy of the

OSHA asbestos standard for general industry may be found at OSHA’s website (www.osha.gov) and should be referred to for specific information.

3.3 Visual Assessment

Our survey activities began with visual observation of the interior of the unit within the renovation scope to identify apparent homogeneous areas of suspect ACM. A homogeneous area consists of building materials, which appear similar throughout in terms of color, texture and date of application. Building materials which were not identified as concrete, glass, wood, masonry, metal or rubber were considered suspect ACM.

3.4 Physical Assessment

A physical assessment of each homogeneous area of suspect ACM was conducted to assess the friability and condition of the materials. A friable material is defined by the EPA as a material, which can be crumbled, pulverized or reduced to powder by hand pressure when dry. Friability was assessed by physically touching suspect materials.

3.5 Sample Collection

Based on our observations, bulk samples of suspect ACMs were collected in general accordance with SCDHEC and EPA sample collection protocols. Random samples of suspect materials were collected in each homogeneous area. Bulk samples were collected using wet methods as applicable to reduce the potential for fiber release. Samples were placed in sealable containers and labeled with unique sample numbers using an indelible marker.

The selection of sample locations and frequency of sampling was based on Terracon’s observations and the assumption that like materials in the same area are homogeneous in content.

A brief summary of suspect ACMs observed and sampled throughout the structure were:

◼ CMU block coating

Non-suspect materials observed include silicon caulking and the rubber membrane roof system.

Table 1 in the Appendix A which summarizes the bulk samples collected from the structure, the results of the visual inspection, estimated quantities, and laboratory analyses. Photograph documentation is presented in Appendix B.

3.6 Sample Analysis

Facilities | Environmental | Geotechnical | Materials 4

Bulk samples were submitted under chain of custody to EMSL Analytical Laboratories in

Pineville, North Carolina for analysis by Polarized Light Microscopy (PLM) with dispersion staining techniques per EPA EPA/600/R-93/116. The percentage of asbestos, where applicable, was determined by microscopical visual estimation. EMSL is accredited under the National

Voluntary Laboratory Accreditation Program NVLAP.

Per the SCDHEC Regulation 61-86.1 Standards of Performance for Asbestos Projects, negative results for non-friable organically bound (NOB) materials such as flooring and roofing shall be verified with at least one TEM analysis. The additional analysis was performed by TEM in accordance with EPA/600/R-93/116 Section 2.5.5.1.

3.7 Findings and Recommendations

Terracon collected a total of three (3) bulk samples of suspect ACMs. Based on the results of laboratory analysis, none of the materials were identified as asbestos containing materials

(ACMs) defined as containing >1% asbestos.

Asbestos laboratory analytical reports, certificates of analysis with the chain of custody, are included in Appendix C.

Recommendations

▪ If applicable to the project, a copy of this report must be submitted to SCDHEC at least ten (10) working days prior to demolition, which includes interior load-bearing walls when applying for a demolition permit.

Should suspect materials other than those which were identified during this survey be uncovered during or prior to the renovation process, those materials should be assumed asbestos-containing until sampling and analysis can confirm or refute their asbestos content.

Should future sampling indicate that the other material is asbestos containing, Terracon recommends removal of the asbestos-containing materials by a South Carolina licensed asbestos abatement contractor prior to renovation/demolition of the building.

4.0 LEAD-BASED PAINT SURVEY

4.1 Regulatory Overview

Lead is regulated by the EPA, SCDHEC and OSHA. The EPA and SCDHEC regulate lead use, removal, and disposal, and OSHA regulates lead exposure to workers. The EPA defines LBP as paint, varnish, stain, or other applied coating that contains lead equal to or greater than

1.0 mg/cm2, 5,000 mg/kg, or 0.5% by dry weight as determined by laboratory analysis.

Facilities | Environmental | Geotechnical | Materials 5

In accordance with SCDHEC solid waste regulations, accumulations of paint wastes (chips, dust, flakes, etc.) and lead contaminated products or other debris shall be tested by the

Toxicity Characteristic Leachate Procedure (TCLP) prior to disposal to determine is the waste is classified as hazardous, which would require disposal in a Subtitle C Landfill. Landfills should be contacted to determine their specific disposal requirements.

For the purpose of the OSHA lead standard, lead includes metallic lead, all inorganic lead compounds, and organic lead soaps. The complete OSHA standard for compliance can be found on OSHA’s website (www.osha.gov). A synopsis of the OSHA regulations (29 CFR

1926.62) and the applicability are as follows:

The OSHA Lead Standard for Construction (29 CFR 1926.62) applies to all construction work where an employee may be occupationally exposed to lead. All work related to construction, alteration, or repair (including painting and decorating) is included. The lead-in-construction standard applies to any detectable concentration of lead in paint, as even small concentrations of lead can result in unacceptable employee exposures depending upon on the method of removal and other workplace conditions. Under this standard, construction includes, but is not limited to, the following:

▪ Demolition or salvage of structures where lead or materials containing lead are present

▪ Removal or encapsulation of materials containing lead

▪ New construction, alteration, repair, or renovation of structures, substrates, or portions containing lead, or materials containing lead

▪ Installation of products containing lead

▪ Lead contamination/emergency clean-up

▪ Transportation, disposal, storage, or containment of lead or materials containing lead on the site or location at which construction activities are performed

▪ Maintenance operations associated with construction activities described above.

4.2 Sampling and Analytical Protocol

Mr. Langford of Terracon conducted the lead-based paint (LBP) sampling on November 9, 2023. The LBP sampling was conducted by collecting paint chip samples. The paint chip samples were collected from painted or lacquered surfaces of building components likely to contain LBP, based on apparent date of application. The paint samples were collected down to the surface substrate so as to include any underlying paint systems in the analysis. The random paint chip samples were selected based on current paint schemes and may not be inclusive of old paint systems covered with paneling, or existing painted systems. The paint chip samples were submitted to an ELAP approved laboratory for analysis of lead by NIOSH

Method 7082M (atomic absorption).

Facilities | Environmental | Geotechnical | Materials 6

4.3 Findings and Recommendations

Based on the results of laboratory analysis, two (2) paint chip samples were collected from the interior and exterior walls. The paint chip lead analyses were below the laboratory detection limits.

Based on the scope of services, limitations, and findings of this assessment, Terracon recommends the following:

▪ Accumulation of Paint residue/waste (chips, dust, flakes, etc.) Work involving any paint removal such as blasting or manual scraping may require laboratory testing by

TCLP to characterize the waste stream and determine proper disposal requirements identified in SCDHEC solid waste regulations or any MCAS Base Environmental requirements.

The analytical report is included in Appendix C.
