EXECUTIVE SUMMARY

Partner Engineering and Science, Inc. conducted a Pre-Demolition Asbestos Containing Material (ACM) and

Lead-Based Paint (LBP) Survey of the Shed at Houma Airport located at 10264 East Main Street in Houma, Louisiana. The survey was conducted in anticipated demolition of the shed structure in general conformance with National Emission Standards for Hazardous Air Pollutants (NESHAP).

Federal and State of Louisiana regulations define asbestos-containing material (ACM) as any material containing more than one percent (1%) asbestos. Asbestos was not detected in the materials sampled. If any suspect ACMs not characterized in this report are encountered during demolition activities, all work that could potentially disturb the materials must stop. Uncharacterized suspect ACM must be assumed to be ACM and handled accordingly, pending the completion of additional sampling and laboratory analysis.

The following building materials are not suspected to be asbestos-containing; therefore, the materials were not sampled: metal walls, metal roof, and styrofoam insulation in wall/ceiling joints.

Lead-based paint LBP) is defined by the Environmental Protection Agency (EPA) as paint or other surface coating with lead content equal to or greater than 1.0 milligrams per square centimeter (mg/cm2) of surface area by X-Ray Fluorescence (XRF) analysis or 0.5% by weight (5,000 parts per million (ppm)) by paint chip analysis. LBP was not detected at or above the EPA action level in the paint chip sample collected and submitted for laboratory analysis.

When conducting construction or demolition activities which disturb lead in any amount or create an exposure to workers, the employer is required to provide worker protection and conduct exposure assessments. Employers should consult Federal Occupational Safety and Health Administration (OSHA)

Regulations at 29 CFR 1926.62, Lead in Construction standards for complete requirements.

Surveyed by: Phillip Bellan, J.D., CIH, CSP – LA DEQ Inspector 187169

Survey date: August 22, 2025

1.2 Purpose and Scope

The pre-demolition asbestos-containing materials (ACM) and lead-based paint (LBP) survey was conducted in accordance with the United States Environmental Protection Agency (USEPA) regulation, 40 CFR Part 61, Subpart M, National Emissions Standard for Hazardous Air Pollutants (NESHAP) and additional requirements of the USEPA and State of Louisiana. The purpose of this survey was to identify, sample and analyze suspect

ACM and LBP on a shed, which is scheduled for demolition. The suspect materials sampled during the survey were limited to accessible areas within the interior and exterior of the building.

Asbestos and lead-based paint may be present in materials not sampled, and additional sampling may be warranted in the event of future disturbance of suspect materials. All suspect materials should be managed in accordance with applicable regulations.

Additional services, such as the interview of property management, maintenance personnel, or tenants, review of prior reports, regulatory records, evaluation of compliance, risk assessment, or the development of abatement specifications were excluded from the scope of services, along with all other activities not expressly identified herein. No demolition, destructive testing, or product research was performed in attempts to reveal material compositions.

September 5, 2025

2.0 METHODOLOGY

2.1 Asbestos

2.1.1 Visual Evaluation

Building materials were observed to identify, classify and evaluate the condition of homogenous areas of suspect ACM. The building stood on a concrete slab as a slab-on-grade structure. The building was a sheet metal style shed with sheet metal attached via screws to a metal frame. The size of the shed structure was approximately 50 square feet.

2.1.2 Classification

Asbestos containing building materials are typically classified as surfacing, thermal systems insulation, or miscellaneous ACM.

Surfacing - Material that is sprayed, troweled-on or otherwise applied to surfaces. Examples include acoustical plaster on ceilings, fireproofing on structural members, or similar applications for acoustical, fireproofing, and other purposes.

Thermal Systems Insulation – Materials applied to pipes, fittings, boilers, breeching, tanks, ducts or other structural components to prevent heat loss or gain.

Miscellaneous – All other ACM including taping mud, floor tile mastic, stucco, leveling compound, etc…

2.1.3 Evaluation of Condition

An assessment of the condition of ACM can be useful in deciding how to management materials. The ACM most likely to release asbestos fibers are those which are in a friable state. The definition of friable is any material, when dry, that is capable of being crumbled, pulverized or reduced to powder by hand pressure

(40 CFR 763). Non-friable sources of asbestos are materials containing cement or asphaltic binder which may become friable and release fibers if the sources are exposed to actions such as abrasion, drilling, cutting, fracturing, or hammering. Non-friable sources of asbestos do not typically pose a significant exposure risk if they remain in good condition and are not disturbed. During renovation or demolition activities, or when subject to abrasive action, non-friable sources may become friable, and may pose an exposure risk.

EPA protocols have been used in the evaluation of the condition of observed materials.

Good – Little or no visible damage or deterioration.

Damaged – Some insulation jackets are missing; water staining; crushing, gouges, punctures, or marring is evenly distributed.

Significantly Damaged – Damaged materials where the damage is extensive or severe. More than

10% of insulation jackets are missing; material is crushed, heavily gouged or punctured more than

10% of pipe runs, risers, boilers, tanks, ducts, etc..

The condition of materials is based upon observations at the time of the assessment, and is independent of the friable or non-friable nature of the materials.

September 5, 2025

2.1.4 Homogenous Areas

The US EPA defines a homogeneous area as “an area of surfacing material, thermal system insulation material, or miscellaneous material that is uniform in color and texture” (40 CFR 763). The collection of a minimum number of representative samples from each homogeneous area is generally required for compliance with federal regulations. If asbestos is identified in any sample from a homogeneous area, then the entire homogeneous area is considered to contain asbestos.

2.1.5 Asbestos Sampling and Laboratory Analysis

A total of six (6) bulk samples of suspect asbestos containing materials were collected for analysis. Selected materials were submitted to Eurofins Built Environment Testing East, LLC for analysis by Polarized Light

Microscopy (PLM) in accordance with EPA Method 600/R-93/116, Method for the Determination of

Asbestos in Bulk Building Materials. Eurofins Built Environment Testing East, LLC is accredited by the

American Industrial Hygiene Association (AIHA) and the National Volunteer Laboratory Accreditation

Program (NVLAP).

2.2 Lead-Based Paint

2.2.1 Lead-Based Paint Sampling and Laboratory Analysis

The exterior and interior of the shed were assessed to evaluate for the presence of presumed LBP. Suspect painted surfaces observed at the time of the inspection were sampled and analyzed for lead content. One

(1) paint chip sample was collected and submitted to EHS Laboratories, a certified laboratory accredited with the Environmental Lead Laboratory Accreditation Program (ELLAP), for analysis by EPA SW-846 Method

7000B: Flame Atomic Absorption Spectrophotometry for Determination of Lead Content in Paint Chip

Samples.

September 5, 2025

3.0 ANALYTICAL RESULTS

Documentation of the laboratory results should be retained as a reference for future renovation and/or demolition activities.

The following building materials are not suspected to be asbestos-containing; therefore, the materials were not sampled: metal walls, metal roof, and styrofoam insulation in wall/ceiling joints.

3.2 Lead-Based Paint Results

Lead-based paint LBP) is defined by the Environmental Protection Agency (EPA) as paint or other surface coating with lead content equal to or greater than 1.0 milligrams per square centimeter (mg/cm2) of surface area by X-Ray Fluorescence (XRF) analysis or 0.5% by weight (5,000 parts per million (ppm)) by paint chip analysis. LBP was not detected at or above the EPA action level as summarized in Table 2 below.

The lead concentration of the sample submitted for analysis was below the regulatory level and is considered negative for LBP. The laboratory results are contained in Appendix A. Sample locations are depicted on the diagram contained in Appendix B.

4.0 CONCLUSIONS/RECOMMENDATIONS

4.1 Conclusions

Asbestos was not detected in the materials sampled.

LBP was not detected at or above the EPA action level in the paint chip sample collected and submitted for laboratory analysis.

4.2 Recommendations

Based on the observations made, the noted limitations and the analytical results, Partner recommends the following: File Form AAC-2(b) with the Louisiana Department of Environmental Quality prior to beginning demolition activity.

If any suspect ACMs not characterized in this report are encountered during demolition activities, all work that could potentially disturb the materials must stop. Uncharacterized suspect ACM must be assumed to be ACM and handled accordingly, pending the completion of additional sampling and laboratory analysis.

All construction work where an employee may be occupationally exposed to lead must comply with

Occupational Safety and Health Administration (OSHA) requirements set forth in 29 CFR 1926.62. This regulation requires initial employee exposure monitoring to evaluate worker exposure during work that disturbs lead-containing materials (lead present in detectable levels). Partner suggests that engineering controls, respiratory protection and personal protective equipment be employed at the start of a project in the presence of lead-containing materials.

Waste items generated during an abatement or demolition project should be properly sampled and profiled to determine the final disposition of the waste. Characterization and disposal of lead-containing waste materials (LCWM) must comply with federal, state and local authorities. Contractors must maintain current licenses as required by applicable state or local jurisdictions for the removal, transport, disposal of LCWM, or other regulated lead-based paint activities.

The potential exists for additional suspect lead-containing materials to be exposed during demolition and/or renovation activities. Such materials should be sampled and analyzed for lead content prior to any renovation and/or demolition activities that could impact these materials.
