1.0 ASBESTOS-CONTAINING MATERIAL SURVEY

The limited asbestos survey was conducted on January 23, 2026, by TDSHS-licensed Asbestos inspectors Deborah Salahuddin (license number 603987), and Nicolas Espino (license number

603646).

1.1 Sampling Methods

TTL performed the limited asbestos inspection survey in general accordance with Texas Department of State Health Services (TDSHS) Administrative Code Title 25, Part 1, Chapter 296, Texas Asbestos

Health Protection Rules (TAHPR), as well as the United States Environmental Protection Agency

(USEPA) National Standards for Hazardous Air Pollutants (NESHAP). Approximate quantities of suspect materials were estimated by field measurements. The condition (e.g., good, damaged, significantly damaged) and friability (i.e., easily crumbled, pulverized, or reduced to powder by hand pressure) of suspect ACM was noted for each material. The friability of each sampled material was determined by hand-touch.

• Surfacing materials, including spray-applied or troweled on wall/ceiling coatings,

• Thermal system insulation (TSI), including pipe insulation, duct insulation, boiler lagging and

• Miscellaneous materials, including ceiling panels/tiles, floor tiles and mastic, gaskets (if accessible), and wallboard/joint compound.

Suspected ACMs were grouped into homogeneous areas (i.e., a material that is uniform in texture, color, date of application, use or system, and appears identical in every other aspect). Homogeneous areas were determined by the TDSHS licensed Asbestos Inspector(s) based upon date of installation and uniformity or color and texture. Fiberglass, foam glass, rubber or wood products, plastic products, glass and steel were not sampled since they are not considered suspect ACM.

1.2 Laboratory Analysis

A total of thirty (30) bulk samples were collected from the selected areas of the interior and exterior of the building. Samples were deposited in secure containers for transport to the analytical laboratory.

Bulk suspect asbestos samples were submitted under secure chain of custody and were analyzed utilizing Polarized Light Microscopy (PLM), following the USEPA PLM Method EPA-600/R-93/116. The bulk samples were analyzed by Moody Labs (Moody), in Farmers Branch, Texas. Moody is accredited by the National Institute of Standards and Technology National Voluntary Laboratory Accreditation

Program (NVLAP No. 102056-0) and licensed by TDSHS (license number 300084).

A summary of TTL’s asbestos sampling, including analytical results, sample number, material descriptions, sample locations, material condition, friability and estimated quantities is provided in

1.4 Asbestos Recommendations

ACMs identified at the building that will be impacted by renovation or demolition should be removed and disposed of in accordance with federal, state, and local regulation, prior to disturbance. It is recommended that the asbestos abatement must be performed by a TDSHS licensed asbestos abatement contractor in accordance with a project design prepared by a TDSHS licensed asbestos consultant. In addition, third party air monitoring should be performed during the abatement. Prior to initiating an asbestos abatement project, written notification must be provided no later than 10 calendar days prior to starting abatement.

TTL Project No. 26-09-00191.00 Page 6 of 14

Contractors should use caution during construction related activities as concealed suspect ACM or other hazardous materials that were not previously analyzed may be encountered. If additional material, not previously sampled are later identified during construction related activities, then supplemental sample should be performed.

Materials that were noted as none-detected for asbestos may be disposed of as general construction debris.

TTL Project No. 26-09-00191.00 Page 7 of 14

2.0 LEAD BASED PAINT SURVEY

As part of the Hazardous Materials Survey, TTL representative Mr. Nicolas Espino, a Texas Department of State Health Services (TDSHS) certified Lead Risk Assessor (license number 2071258) conducted a lead-based paint (LBP) survey at the Site on January 23, 2026.

2.1 Sampling Methods

The LBP sampling was conducted in general accordance with sampling guidelines and methodologies documented in the U.S. Department of Housing and Urban Development (HUD) Guidelines for the

Evaluation and Control of Lead-Based Paint Hazards in Housing, Second Edition dated July 2012 and

EPA Lead: Requirements for Lead-Based Paint Activities in Target Housing and Child-Occupied

Facilities, dated August 1996. Paint chip sampling methods were utilized to complete this survey.

Lead-based paint (LBP) is defined as paint containing >1.0 milligrams per square centimeter (mg/cm2) as measured by >0.5% of lead by weight as analyzed by Atomic Absorption, for the purposes of renovation and/or demolition work. Occupational Safety and Health Administration (OSHA) defines

LBP as any paint containing detectable amounts of lead.

The scope of work required a visual inspection and sampling of all painted surfaces from the Site.

Paint chip samples were collected from painted areas throughout the Site.

2.2 Paint Chip Sample Summary

A total of ten (10) paint chip samples were collected from painted areas at the Site. The samples were submitted to SanAir Technologies Laboratory, North Chesterfield, Virginia. The samples were analyzed for total lead utilizing EPA Method SW846/M3050B/7000B. A summary of the samples collected, and analytical results are presented in Table 2.

Laboratory analysis indicated that one (1) of the ten (10) samples collected from the Site indicated a concentration of lead of 0.5% concentration by weight or greater, as noted below:

• Gray paint on metal (L-03)

A Sample location map depicting all sampling locations is included in Appendix A. The laboratory results can be found in Appendix B.

2.4 Lead Recommendations

Contractor(s) should be made aware of the results for LBP. LBP that is in poor or deteriorated condition or that is disturbed during renovation by dry sanding, scraping, brushing, or burning can produce dust with lead, which can be inhaled or enter the body from hand-to-mouth contact.

Prior to performing renovation or demolition activities, the contractor should be made aware of the presence of LBP or potential LBP particularly in the areas of observed damaged paint to satisfy the hazard communication requirements set forth by OSHA regulations. Specifically, the contractors should be required to comply with OSHA regulations including 29 CFR 1926.62, Lead Exposure in

Construction: Interim Final Rule and 29 CFR 1926.59, Hazardous Communication for the Construction

Industry.

If any renovation, repair or demolition activity will disturb the LBP, engineering controls such as barriers and water should be used to minimize dust levels. The public should be prevented from unauthorized access to the work area. Ambient air monitoring is recommended to document engineering controls are adequate and that the ambient airborne concentrations do not exceed the permissible exposure levels.

TTL Project No. 26-09-00191.00 Page 9 of 14

3.0 LIMITED HAZARDOUS COMPONENTS SURVEY

As part of this Hazardous Materials Survey, a Limited Hazardous Components Survey was conducted at the Site on January 23, 2026.

3.1 Purpose and Scope

The purpose of the Hazardous Component Survey was to visually identify suspect hazardous components at the Site. This survey included identifying equipment that may contain Polychlorinated

Biphenyls (PCBs) or Mercury that may be handled during renovation. These components may be subject to special handling for recycling or waste disposal prior to demolition activities. A hazardous component location map can be found in Appendix E.

3.2 Polychlorinated Biphenyls

PCBs are a class of man-made organic chemicals manufactured and used from the late 1920s until

1979 when the EPA banned its manufacture. PCBs are stable, resistant to acids and bases, have thermal stability, and fire resistance properties. These special properties led to widespread use of

PCBs in industrial and commercial applications including electrical, heat transfer, hydraulic, and lighting equipment, caulks, paint, coatings, etc. The EPA regulates PCBs through several statutes, the most comprehensive of which is the Toxic Substances Control Act of 1976 codified in 40 CFR Part

761. This regulation governs the use, marking, storage, recording, and disposal of PCBs and PCB wastes. In Texas, PCB waste is regulated by the Texas Commission on Environmental Quality (TCEQ) through 30 Texas Administrative Code (TAC) Chapter 335.

Fluorescent Lamp Ballasts

Fluorescent Lamp Ballasts (FLBs) manufactured prior to July 1, 1979 may contain PBCs. FLB manufactured between July 1. 1978 and July 1, 1998 that do not contain PCBs must be labeled “No

PCBs”. If an FLB is not labeled "No PCBs", it is best to assume it contains PCBs unless it is known to be manufactured after 1979. FLBs manufactured after 1998 are not required to be labeled.

To inspect a light fixture for the presence of PCBs, parts of the fixture were temporarily removed to expose the ballast (if present) and identify a “no PCBs” label. A photograph was taken for every newly encountered ballast before the fixture was reassembled. Details regarding the styles of fluorescent light fixtures identified are provided below.

Approximately four (4) individual ceiling mounted FLBs were observed inside the building.

Approximately 10% of these fixtures were disassembled. The “No PCBs” label was not observed on the

FLBs. Additional investigation is required to determine the presence of PCBs in the dielectric fluids therein.

Electric Transformers

Dielectric fluids in electrical transformers may contain PCBs. Pad mounted transformers were observed along Walker Avenue to the east of the building. The labels did not indicate the presence or absence of PCBs – additional investigation is required to determine the presence of PCBs in the dielectric fluids therein.

3.3 Mercury

Mercury is found in thermostats, switches, thermometers, compact fluorescent bulbs and fluorescent and high-intensity discharge lamps.

All four (4) ballasts at the Site were equipped with two (2) mercury containing fluorescent tube bulbs.

They should be disposed of in accordance with applicable rules and regulations. All fluorescent bulbs must be disposed of as a Universal Waste at an EPA approved recycling facility prior to any renovation

/ demolition activities.

TTL Project No. 26-09-00191.00 Page 10 of 14

The building is conditioned with a wall mounted unit with a built-in thermostat. The thermostat is electric and does not contain mercury. All thermostats must be disposed as a Universal Waste at an

EPA approved recycling facility prior to any renovation / demolition activities.

4.0 LIMITED MOLD ASSESSMENT

As part of the Hazardous Materials Survey, On January 23, 2026, TTL representative Mr. Nicolas

Espino, a Texas Department of Licensing and Regulation (TDLR) licensed Mold Assessment Consultant

(MAC) completed a limited mold assessment and sampling of the Site area, which included the following.

4.1 LIMITED MOLD ASSESSMENT METHODS

TTL conducted a limited mold assessment in accordance with TDLR Texas Mold Assessors and

Remediators Administrative Rules (TMARR) as well as applicable portions of the Institute of Inspection, Cleaning and Restoration Certifications (IICRC) Standard and Reference Guide for Professional Water

Damage Restoration, Fourth Addition and the American Society for Testing and Materials (ASTM)

D7338-14 Standard Guide for Assessment of Fungal Growth in Buildings. The assessment included the following:

4.1.1 Building Materials Moisture Assessment

The relative moisture content (MC) of building materials potentially affected by moisture/water intrusion were measured by a moisture meter and or an infrared (IR) camera to identify temperature differentials that may be associated with wet building materials.

4.1.2 Indoor Air Parameters

TTL collected measurements of indoor relative humidity and temperature concentrations, as well as outdoors for comparison purposes utilizing a hand-held direct read instrument.

4.1.3 Bioaerosol Samples

Samples were collected in accordance with the American Council of Government Industrial Hygienist

(ACGIH) protocol outlined in “Bioaerosols: Assessment and Control”. Samples were collected by drawing air across an adhesive material within a “spore trap” cassette. Ambient air is drawn over the spore trap using a high-volume vacuum pump, calibrated to draw 15 liters of air per minutes, for five minutes.

4.2 MOLD ASSESSMENT FINDINGS

4.2.1 Visual Observations and Building Materials Moisture Assessment

Areas of suspect water damage were observed on the east side interior of the building. Water intrusion appears to originate from roof leakage.

Moisture meter readings were taken from the building materials at the Site indicated the materials were dry at the time of the assessment.

4.2.2 Indoor Air Parameters

The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) Standard

62.1-2016, Ventilation for Acceptable Indoor Mold recommends an indoor temperature of 680

Fahrenheit (F) to 740F in the winter and 720F to 800F in the summer, and an indoor relative humidity

(RH) level of <65% to reduce the likelihood of conditions that can lead to microbial growth. Table 3, found below, lists the conditions observed during the assessment.

The RH reading taken at the Site showed RH was significantly above normal range, which could be attributed to faulty seals on doors and windows in the building. The temperature throughout the building was below industry standards.

4.2.2 Bioaerosol Sample Results

One (1) indoor spore trap sample was collected from the Site, and one (1) outdoor sample for comparison. Samples were submitted under chain of custody to Moody Labs (Moody) located in

Farmers Branch, Texas. Moody is a TDLR license Mold Lab (LAB0117) and accredited by the American

Industrial Hygiene Association (AIHA) (102577). Summary of sample results can be found on the table below:
