Terracon Project No. 92247419

Dear Mr. Baker:

The purpose of this report is to present the results of an interior path-of-construction (POC) asbestos and lead inspection performed on May 6, 2024 at the above-referenced location. This inspection was conducted in general accordance with our proposal dated April 30, 2024. We understand the purpose of this inspection is to identify and quantify accessible asbestos and lead-containing materials in the building prior to renovations.

Asbestos-containing materials were not identified in the materials sampled and submitted for analysis on May 6, 2024. Three out of four paints sampled as part of this inspection were found to contain lead in concentrations below the detection limits. One paint combination was found to be lead-containing and in a concentration that OSHA would consider to present a workforce hazard.

Terracon appreciates the opportunity to provide this service to The Johnson-McAdams Firm, P.A. If you have any questions regarding this report, please contact us at 713-690-8989.

Sincerely, Terracon Consultants, Inc.

Asbestos and Lead Inspection Report

Children’s Nutrition Research Center | Houston, Texas

Facilities | Environmental | Geotechnical | Materials 1

Introduction

Terracon Consultants, Inc. (Terracon) conducted an interior path-of-construction (POC) asbestos and lead inspection of the Texas Children’s Nutrition Research Center, located at 1100 Bates Avenue, in Houston, Texas. The inspection was conducted on May 6, 2024, by a State of Texas licensed asbestos consultant and by a State of Texas licensed asbestos inspector in general accordance with Terracon Proposal No. P92247419 dated April 30, 2024.

Homogeneous areas of suspect asbestos-containing materials (ACM), and lead-based paint (LBP) were visually identified and documented. Although reasonable effort was made to sample accessible suspect materials, additional suspect but un-sampled materials could be located in walls, under carpet, in voids or in other concealed areas. Suspect ACM samples were collected in general accordance with the sampling protocols outlined in EPA regulation 40 CFR 763 (Asbestos Hazard Emergency Response Act, AHERA) and the Texas Asbestos Health Protection Rules (TAHPR). ACM samples were delivered to a State of Texas licensed laboratory for analysis by polarized light microscopy. LBP samples were delivered to an AIHA-accredited laboratory for analysis by Flame

AAS – USEPA SW846 7420/3050B.

Project Objective

We understand this asbestos and LBP inspection was requested because of the planned renovations of select areas of the building. The TAHPR require that an asbestos inspection be performed prior to issuance of a city construction permit (Senate Bill 509) and prior to any renovation within or demolition of a building. 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 or demolition activities. The asbestos NESHAP requires that potentially regulated asbestos-containing building materials be identified, classified and quantified prior to planned disturbances or demolition activities.

OSHA regulations govern exposure of workers to lead regardless of the concentrations of lead identified in paint. The OSHA regulations, which have been established for general and construction industries, cover any type of workplace activity that could expose an employee to potential asbestos or lead contamination (OSHA Standards 29 CFR 1926.1101 and 1926.62).

Building Descriptions

The site building consists of a multi-level federal nutrition research center reportedly built in 1978. The building exterior consists of decorative stone, plaster, concrete and glass. Interior wall finishes consist of gypsum wallboard and wood panels. Floors consist of decorative stone, vinyl floor tile and carpet.

The ceilings consist of 2’x4’ suspended ceiling tile, wallboard and plaster. Based on the information provided by the client, the POC areas were limited to various levels of the building but exclusively to areas above the ceilings/ceiling grid.

Field Activities

The asbestos and lead inspections were conducted by John Stone, a state of Texas licensed asbestos consultant and Aaron Dominguez, a State of Texas licensed asbestos inspector employed by Terracon.

Copies of their licenses are included in Appendix G. The inspection was conducted in general accordance with the sample collection protocols established in AHERA and required by TAHPR.

Additionally, The State of Texas regulations govern lead-based paint activities only in target housing or child-occupied facilities. Since the building is not considered target housing or a child-occupied facility, state certification is not required to collect samples. A summary of inspection activities is provided below.

Visual Assessment

Asbestos

Our inspection activities began with visual observation of the POC areas to identify homogeneous areas of suspect ACM. A homogeneous area consists of building materials that appear similar throughout in terms of color, texture and date of application. Assessment was conducted throughout visually accessible areas of the POC. Materials identified as glass, wood, masonry, metal or rubber are not considered suspect ACM. Assessment was conducted throughout visually accessible areas of the building.

Lead-Containing Materials

Our inspection activities began with visual observation of the POC areas to identify apparent homogeneous areas of suspect LBP. A homogeneous area consists of paints that appear similar throughout in terms of color, texture and date of application.

Physical Assessment

Asbestos

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 that can be crumbled, pulverized or reduced to powder by hand pressure when dry. Friability was assessed by physically touching suspect materials.

A physical assessment of each homogeneous area of suspect LBP was conducted to assess the condition of the materials. A visual determination of damage to the materials was performed.

Sample Collection and Analysis

Asbestos

Based on results of the visual observation, bulk samples of suspect ACM were collected in general accordance with AHERA sampling protocols and the TAHPR. Random samples of suspect materials

Facilities | Environmental | Geotechnical | Materials 3 were collected in each homogeneous area. The asbestos inspector collected bulk samples 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.

Thirty (37) bulk samples were collected from nine (9) homogeneous areas of suspect ACM. A summary of suspect ACM samples collected during the inspection is included in Appendix A.

Bulk samples were submitted under chain of custody to Eurofins J3 Resources, Inc. (J3) of Houston, Texas, for analysis by polarized light microscopy per EPA methodology EPA/600/R-93/116. The percentage of asbestos, where applicable, was determined by microscopic visual estimation. J3 is accredited under the National Voluntary Laboratory Accreditation Program (NVLAP Accreditation No.

200525-0) and licensed by the TDSHS (TDSHS No. 30-0273).

Based on results of the visual observation, samples of suspect LBP were collected. Random samples of suspect materials were collected in each homogeneous area. Samples were placed in sealable containers and labeled with unique sample numbers using an indelible marker.

Four (4) bulk samples were collected of suspect LBP. Paint chip samples were collected from the following surfaces:

Tan paint of gypsum wallboard walls in the Calibration Lab

Beige paint on hard plaster ceiling in the Caloric Lab Terrace (sample at this location due to height accessibility concerns in the auditorium)

Green paint on steam pipe insulated valves in the Main Mechanical Plant

Yellow paint on steam pipe insulated valves in the Main Mechanical Plant

Paint chip samples were submitted under chain of custody to Eurofins J3 Resources, Inc. (J3) of Houston, Texas, an American Industrial Hygiene Association (AIHA) accredited laboratory utilizing Atomic Absorption Spectrometry (AAS Flame) methodology SW846 7000B/3050B. A summary of the collected suspect LBP samples is presented in Appendix C.

Regulatory Overview

Asbestos

The Texas Department of State Health Services (TDSHS) enforces the Asbestos NESHAP as adopted by reference at Texas Administrative Code Title 25, Part 1, Chapter 296, Subchapter A, Rule §296.3.

The asbestos NESHAP regulates asbestos fiber emissions and asbestos waste disposal practices. It also requires the identification and classification of existing materials prior to demolition or renovation activity. NESHAP defines ACM as material containing greater than one percent (>1%) asbestos. Under NESHAP, ACM 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. Category I non-friable ACM include packings, gaskets, Facilities | Environmental | Geotechnical | Materials 4 resilient floor coverings and asphalt roofing products containing more than 1% asbestos. Category II are any non-friable materials other than Category I materials that contain more than 1% asbestos.

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

The TDSHS also enforces the Texas Asbestos Health Protection Rules (TAHPR), which defines ACM as a material containing one percent or greater (>1%) asbestos. TAHPR requires that any asbestos-related activity conducted in a public building be performed by personnel licensed by the TDSHS.

RACM must be removed prior to renovation or demolition activities that will disturb the materials.

Asbestos abatement must be performed by TDSHS-licensed asbestos abatement contractors in accordance with a project design prepared by a TDSHS-licensed asbestos consultant. Third-party air monitoring must be conducted prior to, during and following the abatement activities.

Management Plans developed for the in-place management of asbestos-containing materials must be developed by a TDSHS-licensed management planner.

Both NESHAP and TAHPR require that the owner or operator of a building must provide the TDSHS with written notification at least ten working days prior to the commencement of asbestos abatement activities that will disturb any amount of RACM. Written notification is also required for demolition of any building, even those that do not contain ACM. Please note that TAHPR does not apply to federal properties.

The Occupational Safety and Health Administration (OSHA) standards at 29 CFR 1910.1001 and 29 CFR 1926.1101 regulate employee exposure to asbestos. These OSHA standards require that employee exposure to airborne asbestos fibers be maintained below 0.1 asbestos fibers per cubic centimeter of air (0.1 f/cc) as an 8-hour time-weighted average (TWA) and not exceed 1.0 asbestos fibers per cubic centimeter of air (1.0 f/cc) over a 30-minute time period, the excursion limit. The TWA and excursion limit together are known as the OSHA permissible exposure limits or PELs. The OSHA standard 29 CFR 1926.1101 categorizes activities that will disturb ACM into four classes and specifies work practices that must be followed when performing each class of work.

Lead

OSHA regulations govern exposure of workers to lead regardless of the concentrations of lead identified in paint. The OSHA regulations, which have been established for general and construction industries, cover any type of workplace activity that could expose an employee to potential lead contamination (OSHA Standards 29 CFR 1926.62 and 1910.1025).

The OSHA standards for lead require that employee exposure to airborne lead be maintained below 50 micrograms of lead per cubic meter of air calculated as an eight-hour time-weighted average (TWA). The OSHA construction standard classifies construction activities that could result in exposure to airborne lead and specifies training requirements, engineering controls and work practices that must be followed when engaging in those activities.

Facilities | Environmental | Geotechnical | Materials 5

EPA’s Renovation, Repair and Painting (RRP) Rule addresses lead-based paint hazards created in target housing and child-occupied facilities. Target housing is a home or residential unit built before 1978. There are exceptions for elderly and disable persons and zero-bedroom dwellings. A child-occupied facility is a pre-1978 building that is visited regularly by the same child (under 6 years of age), for at least two different days during the week, and each visit lasts at least 3 hours. The combined weekly visits must be at least 6 hours, and the combined annual visits must be at least 60 hours. The RRP Rule Requires:

Renovators (individuals) performing work in target housing or child-occupied facilities must be trained and certified.

Renovation firms must be certified.

Non-Certified workers must work under and be trained on-the-job by a certified renovator.

Lead safe work practices must be followed.

Certified renovators must educate owners/occupants.

Training providers must be accredited.

The requirements listed above are triggered if renovation, repair, or painting activities will disturb more than 6 square feet of interior lead-based paint or 20 square feet of exterior lead-based paint in target housing or child-occupied facilities. Please note that the RRP does not replace lead-based paint abatement regulations (40 CFR 745.223) or the OSHA Lead in Construction Standard (29 CFR 1926.62). Federally assisted target housing must address lead hazards under the U.S. Department of Housing and Urban Development (HUD) Guidelines.

In the State of Texas, the Texas Environmental Lead Reduction Rules govern lead-based paint (containing 0.5% or greater lead by weight) in target housing (built before 1978) or child-occupied facilities such as day-care centers. Lead-containing paint in other types of facilities is not covered by state regulations in Texas.

Findings and Recommendations

Asbestos

Asbestos was not identified in the samples collected on May 6, 2024. A summary of the classification, condition and quantity of the sampled suspect ACM is presented in Appendix A. The Laboratory analytical report is included in Appendix B.

If suspect asbestos-containing materials are discovered during the course of the demolition that were not sampled as part of this inspection, they should not be disturbed until the presence of asbestos is either confirmed or ruled out by laboratory analysis.

Lead

Three out of four paints sampled as part of this inspection on May 6, 2024 were found to contain lead in concentrations below the detection limits. One paint combination was

Facilities | Environmental | Geotechnical | Materials 6 found to be lead-containing and in a concentration that OSHA would consider to present a workforce hazard.

It is recommended that contracting personnel who may disturb the lead-containing paint and/or coatings that are present on-site structures be made aware of the lead content in the materials so that they may exercise proper OSHA procedures for personnel protection and/or possibly employ protective procedures (US EPA Lead-Safe Work Practices) when working with the materials.

It is recommended that any metal components associated with the site structures that will be removed be segregated from the waste stream and be recycled rather than disposed of.

Compliance with applicable OSHA lead regulations is the responsibility of the contractor performing the work, and it is recommended that they be required to communicate potential lead hazards to their workforce and utilize lead-safe work practices such as outlined in the EPA Renovation, Repair, and Painting Final Rule (40 CFR 745) or applicable portions of the Structural Steel Painting Council (SSPC) Guidelines.

It is further recommended that activities such as flame/torch dismantling, dry sanding and/or dry grinding of any components with lead-containing paint materials applied should be prohibited as part of any repair, renovation or demolition activity.

The identified lead-containing paint may become a source of lead-containing dust during demolition/renovation activities. Activities that generate airborne dust from paint containing any concentration of lead are regulated under the OSHA Construction Standard 29 CFR 1926.62.

If additional suspect lead-based paint is discovered during the course of renovation or demolition work that were not sampled as part of this inspection, they should not be disturbed until the presence of lead is either confirmed or denied by laboratory analysis.

A summary of the lead paint samples is presented in Appendix C. The Laboratory analytical report is included in Appendix D.
