LIMITED ASBESTOS SURVEY

Building 6418 - Mexican Fruit Fly Rearing Facility & Colony Holding USDA Moorefield

Texas State Environmental Consult ing

INTRODUCTION

Texas State Environmental Consulting (TSEC) conducted an asbestos survey located at:

Building 6418 - Mexican Fruit Fly Rearing Facility & Colony Holding Rooms

Bulk samples of suspect Asbestos-Containing Building Materials (ACBM) were collected within these areas of the buildings. The scope of work included: Review of previous documentation (if provided), inspecting and sampling for suspect asbestos materials.

SCOPE OF SERVICES

Samples were collected, and analytical tests were performed for determining whether ACBM were present within the building and/or ACM were present from the exterior of the building. The survey follows applicable state and federal regulations governing asbestos work and can be relied on for demolition activities.

TSEC conducted a visual inspection of the building materials. During the walk-through, suspect asbestos materials were noted. Their condition and friability were also noted.

Regarding asbestos, a homogeneous area (an area of material that is uniform in color and texture) shall be determined to contain asbestos if the results of at least one sample collected from it indicate that asbestos is present in an amount greater than one percent (>1%). Once a material has been found to contain asbestos, all such materials in the defined homogenous area are considered to contain asbestos.

SAMPLING

Mr. Jose S. Juarez, Jr., an individual asbestos consultant licensed by the Texas Department of State Health Services (TDSHS License #10-5775) conducted the site sampling survey on October 13, 2025. This survey was conducted in general accordance with the Federal NESHAP and State regulations for the presence of ACMs. The survey was characterized by a visual inspection and sampling of suspect structure components at the subject property to be impacted by demolition or renovation activities. Guidelines utilized in the asbestos survey were established by the Texas Asbestos Health Protection Rules (TAHPR §296). A total 7 Bulk samples of suspect asbestos materials were collected.

Suspect asbestos materials, which are alike in appearance and application, were sampled as a homogeneous area. Suspect homogeneous areas are divided into three classifications:

1. Surfacing materials: Spray-applied or troweled on material.

2. Thermal Systems Insulation: Pipe, boiler, tank, or flue insulation.

3. Miscellaneous: Other suspect material, including floor tile and mastic, sheet vinyl flooring, ceiling tiles, insulation mastics, cove base mastic, window caulking, and exterior siding.

Suspect materials sampled and analyzed should be considered homogeneous area if:

• They exhibit similar physical characteristics.

• The application of the sampled material can be correlated to the application of un-sampled material.

Representative sampling was based on:

• Distribution of the suspect materials throughout the homogeneous area.

• The suspect material’s physical characteristics and application.

• Random sampling patterns determined for each homogeneous area.

ANALYTICAL PROCEDURES

Bulk samples were analyzed under polarized light microscopy (PLM), by Eurofins Houston, Texas, utilizing the Environmental Protection Agency’s Method for the Detection of Asbestos in Bulk Insulation Samples, (Method EPA 600/R-93/116, July 1993).

Eurofins Houston, Texas, is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP# 200525- 0), participates in the NVLAP and AIHA Bulk Asbestos Sample Quality Assurance Programs and is licensed to analyze bulk asbestos samples collected in the State of Texas (TDSHS License #30-0273).

913 White Coating (Layer 1) None Detected 85% Non-Fibrous, 15% Glass Fibers Good

913 (L2) Black Mastic (Layer 2) None Detected 100% Non-Fibrous Material Good

CONCLUSIONS AND RECOMMENDATIONS

No asbestos fibers were detected in the samples retrieved You may proceed with your demolition as planned. All samples analyzed by PLM were reported as “None Detected” for asbestos fibers. Based on EPA and TDSHS regulatory thresholds, no asbestos-containing material (ACM) was identified in the sampled materials.

The building materials tested are non-regulated under NESHAP (40 CFR 61, Subpart M) and TDSHS definitions of ACM (>1% asbestos by weight).

However, during any renovation or demolition, all unassessed materials or newly exposed materials should be assumed suspect until further sampling verifies asbestos content.

WARRANTY

These observations and results are time dependent, are subject to changing site conditions, and revisions to Federal, State, and local regulations. TSEC warrants that these findings have been promulgated after being prepared in general accordance with generally accepted practices in the asbestos testing and abatement industries. TSEC also recognizes that raw laboratory test data are not usually enough to make all abatement and management decisions. No other warranties are implied or expressed.

The total percentage of sample components shown may be greater than 100% when some components are detected at <1%.

The test report shall not be reproduced except in full, without written approval of the laboratory. The report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST, or any agency of the federal government. The Company reserves the right to dispose of all samples after a period of thirty (30) days, according to all state and federal guidelines, unless otherwise specified.

Inhomogeneous samples are separated into homogeneous subsamples and analyzed individually. ND means no fibers of that type were detected.

When detected, the minimum detection and reporting limit is less than 1% unless point counting is performed. Floor tile samples may contain large amounts of interference material and it is recommended that the sample be analyzed by gravimetric point count analysis to lower the detection limit and to aid in asbestos identification.

‡ A "Version" indicated by -"x" after the Lab ID# with a value greater than 1 indicates a sample with amended data. The revision number is reflected by the value of "x".
