Subject: Asbestos Survey Report of Findings - Vacant Residential Structures Located at 3399 Hero Way, Leander, Texas

Limited Pre-Demolition Asbestos Survey Atlas Project Number 350SCF0039

Dear Ms. Dworaczyk:

Atlas Technical Consultants, LLC (Atlas) was retained by Sheets and Crossfield, P. C. to perform a limited pre-demolition asbestos survey of the accessible suspect asbestos-containing building materials within vacant residential structures located at 3399 Hero Way, Leander, Texas. This survey included a visual inspection and physical assessment to identify suspect asbestos-containing materials (ACMs), including the sampling and laboratory analysis of suspect friable and non-friable ACM within the residential structures.

Site Description The vacant structures were surveyed on August 19, 2025, and bulk samples of ACMs expected to be disturbed during any future demolition were collected. Results for suspect sampled ACM’s are included in Table 1. The property includes one vacant residential, two garages and a shed consisting of single-story wood frame with exterior wood and transite panel veneers on a slab foundations. The vacant residential structures have conventional wooden truss pitched roofs with asphalt shingle coverings. Interior walls and ceiling systems are comprised of drywall/joint compound with texturing and wood wall paneling. The flooring throughout consists of carpeting and vinyl tile with associated mastics and exposed concrete. No central heating/cooling systems were present.

ACM Survey Bulk sampling was conducted in general accordance with procedures outlined in the Asbestos Hazard Emergency Response Act (40 CFR 763.86), Texas Department of State Health Services (TDSHS) Texas Asbestos Health Protection Rules (TAHPR) and the U.S. Environmental Protection Agency (EPA) guidance document entitled Guidance for Controlling Asbestos- Containing Materials in Buildings (Document No. 560/5-85/024). The asbestos survey was performed by Mr. Adrian Galaviz with Atlas (TDSHS Asbestos Inspector License No. 604014) on August 19, 2025.

On August 19, 2025 Atlas collected thirty-five (35) bulk samples of suspect ACMs from the surveyed areas of the vacant residential structures. These materials and locations are listed in Table 1.

3399 Hero Way, Leander, Texas

The collected samples were analyzed by Omni Environmental, Inc. (TDSHS Laboratory License No. 30-0087) in Round Rock, Texas using approved polarized light microscopy with dispersion staining (PLM/DS) methods. Omni Environmental is accredited with the EPA Interim Asbestos Bulk Sample Analysis Quality Assurance Program and the National Voluntary Laboratory Accreditation Program (NVLAP Code No. 102061-0). The PLM/DS analytical method is modeled after U.S. EPA Publication EPA/600/R-93/116: Test Method for the Determination of Asbestos in Bulk Materials, July 1993. If a material is identified as containing equal to or greater than 1% asbestos, it is considered to be an ACM. The Bulk Sample Analysis Reports, Atlas Chain of Custody, and applicable licenses/certifications, are attached.

Conclusions-ACM Survey A material is considered by the TDSHS, TAHPR, and USEPA to be asbestos-containing if at least one sample collected from the homogeneous area has asbestos present in concentrations equal to or greater than one percent (>1.0%). Atlas conducted condition assessments and collected bulk samples of suspect ACMs. Table 1 presents a summary of laboratory analysis of the sampled suspect ACMs.

No asbestos (greater than 1%) was identified in any of the sampled materials.

Recommendations Based on the results of the limited asbestos survey, Atlas makes the following recommendations:

All sampled building materials that may be impacted by any upcoming demolition may be disturbed and/or demolished and disposed of as common construction/demolition debris as they all tested non-detect for asbestos.

If any additional materials are discovered during demolition activities, such materials must be assumed to contain asbestos until sampling and analysis proves otherwise.

Efforts were made to locate all suspect asbestos containing materials within the subject site. If additional suspect ACM is encountered during demolition or renovation activities, these materials should be assumed to be ACM until bulk sampling proves otherwise.

ANALYTICAL METHOD: EPA Method for the Determination of Asbestos in Bulk Building Materials (EPA 600/R-93/116) and EPA Interim Method for the Determination of Asbestos in Bulk Insulation Samples (EPA 600/M4-82-020).

Percentages are visual estimates based on sample volume. Limit of Detection: <1%. Limit of Quantification: 1%.

Negative results of resinously bound materials such as roofing material or floor tile may be inconclusive. NAD means No Asbestos was Detected in the sample or layer. The term texturizer (where applicable) may include wall texturizing, tape and bed, and/or joint compound. This report relates only to the item tested as received. It may not be used to claim product endorsement by NVLAP, NIST or any agency of the federal government.

This report may not be reproduced, except in full, without the expressed written consent of laboratory management. Subsamples of layers or other inhomogeneities were analyzed separately and their results combined in proportion to the quantity of each layer to obtain quantitative results for the sample as a whole. All samples are stored for 1 month from the original analysis date before being disposed of.

The following procedures were used in sample analysis unless otherwise noted.
