Re: Hazardous Materials (HAZMAT) Report Joint Base San Antonio (JBSA) - Camp Bullis Building 5907 5907 Doughboy Path San Antonio, Texas 78257 Astex Project No.: AE2620330

Mr. Martinez:

Pursuant to your request, the following are the results of the Hazardous Materials (HAZMAT) Survey for Lead-Based Paint (LBP) and Asbestos Containing Materials (ACM) conducted by Astex Environmental Services (Astex) representatives. The survey included a lead-based paint inspection and an asbestos survey as well as a cursory review for Polychlorinated Biphenyls (PCBs) and Mercury (Hg).

LBP: This structure is classified as a non-residential facility and does not meet the definition of target housing or a child-occupied facility as outlined by the U.S. Department of Housing and Urban Development (HUD) and U.S. Environmental Protection Agency (EPA) guidelines. Therefore, the requirements of the Texas Environmental Lead Reduction Rules (TELRR), the EPA Renovation, Repair, and Painting (RRP) Rule, and HUD LBP regulations do not apply to this property. However, the Occupational Safety and Health Administration (OSHA) regulations for worker protection during activities that may disturb painted surfaces remain fully applicable and are always recommended to be followed.

ACM: This asbestos survey was conducted in accordance with the Texas Asbestos Health Protection Rules (TAHPR) and applicable federal regulations under the National Emission Standards for Hazardous Air Pollutants (NESHAP) 40 CFR Part 61, Subpart M. The purpose of this survey was to identify the presence, location, and approximate estimated quantity of ACBM prior to planned demolition, as required by state and federal law.

Hazardous Materials (HAZMAT) Report JBSA - Camp Bullis —- Building 5907 5907 Doughboy Path, San Antonio, TX 78257 summary of Results Based on thorough observations made on-site, as well as the comprehensive analysis of the data collected, we have compiled the following detailed results.

Lead-Based Paint (Section A):

o Lead-Based Paint (LBP) identified as “positive” and Paint containing

Lead (PCL) identified as “present” was determined to be on select surfaces.

o While abatement is not mandated for non-residential facilities, OSHA regulations require protective measures for workers during disturbance of these materials.

o All contractors performing work on-site are solely responsible for OSHA compliance, including the imple1mentation of site-specific Health and Safety Plans (HASPs) addressing lead exposure risks.

Asbestos (Section B):

o The building materials tested were laboratory analyzed and determined to be asbestos containing in the tar mastic on the bench and the 6-inch Transite pipe located in the men’s shower room. In accordance with TAHPR, special handling, removal procedures, or regulatory restrictions are required for these materials prior to or during repair, renovation, maintenance or demolition activities.

o This asbestos survey fulfills the regulatory requirements for public buildings prior to any renovation or demolition activities, as mandated by NESHAP. This report must be provided to all contractors and relevant parties involved in the project to ensure the safe and legal handling of any ACBM. Failure to comply with these requirements may result in regulatory enforcement actions and penalties.

Polychlorinated biphenyls (PCBs) (Section D):

o On the date of the inspection (June 26, 2026), fluorescent lights were identified on sight. The dismantling of these lights to reveal the labeling of the transformers will identify the use of PCBs in these products. Contractors removing these fixtures must make that determination prior to disposal and treat the waste materials accordingly.

Mercury (Hg) (Section E):

o No noteworthy building components containing Hg were identified.

Section A: Lead-Based Paint Inspection

On June 26, 2026, Mrs. Leonora Becknal, TDSHS Lead Risk Assessor, No. 2070705, of Astex, TDSHS Lead Firm, No. 2110460, inspected the above-referenced project location for the purpose of performing a lead-based paint (LBP) inspection.

For this survey, Astex conducted lead-based paint (LBP) testing utilizing a Viken Pb200e X-Ray Fluorescence (XRF) portable paint analyzer in accordance with the federal regulations of the Environmental Protection Agency (EPA) Renovation, Repair and

Painting (RRP) and Federal Housing and Urban Development (HUD). Astex secured a total of seventeen (17) individual paint readings from randomly selected exterior surfaces.

Since the buildings at this location are not categorized as “target housing” and/or “a child occupied facility’, in accordance with the HUD Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing (2012 Edition), it is exempt from federal HUD regulations and the Texas Environmental Lead Reduction Rules (TELRR).

This LBP testing was conducted in orderto predetermine the potential representative lead content of the buildings’ components. The EPA and the HUD guidelines, established for testing within child occupied facilities and target housing, categorize paint chip samples with levels at or above 0.5% (5,000 parts per million (ppm)) by weight, positive for LBP.

The Occupational Safety and Health Administration (OSHA) lead standard for worker protection during lead paint removal or maintenance activities (i.e., 29 CFR 1910.1025 for General Industry and 29 CFR 1926.62 for Lead — Construction), the EPA- Resource Conservation and Reclamation Act (RCRA) and the Texas Commission on Environmental Quality (TCEQ) for disposal of lead-containing (waste) materials, require identification of the lead content prior to demolition/disposal.

Visual Assessment The evaluation of the property consisted of a visual assessment of the area’s components. Overall, the condition of the painted surfaces was determined to be in deteriorated condition due to moisture and weathering.

Astex Project No.: AE2620330 3

5907 Doughboy Path, San Antonio, TX 78257

Inspection A lead-based paint hazard is any condition that causes exposure to lead from dust-lead hazards, soil-lead hazards, or lead-based paint that is deteriorated, or present in chewable surfaces, friction surfaces, or impact surfaces that would result in adverse human health effects.

According to the EPA, Title X (“ten”) of the Housing and Community Development Act of 1992, defines lead-based paint inspection (in two places, with slightly different formatting of the same wording) as:

a surface-by-surface investigation to determine the presence of lead-based paint as provided in section 302(c) of the Lead-Based Paint Poisoning Prevention Act and the provision ofa report explaining the results of the investigation. (15 U.S.C.

2681(7), for use by EPA and its stakeholders; and 42 U.S.C. 4851(12), for use by HUD and its stakeholders)

This definition in Title X is based on, and mentions, the earlier Lead-Based Paint Poisoning Prevention Act (Public Law 91-695), enacted in 1971, which described an inspection in its section 302(c) as being an:

inspection of all intact and nonintact interior and exterior painted surfaces of housing subject to this section for lead-based paint using an approved x-ray fluorescence analyzer, atomic absorption spectroscopy, or comparable approved sampling or testing technique. A certified inspector or laboratory shall certify in writing the precise results of the inspection. If the results equal or exceed a level of 1.0 milligrams per centimeter squared or 0.5 percent by weight, the results shall be provided to any potential purchaser or tenant of the housing. (42 U.S.C.

4822(c))

The sampling and testing protocols in this chapter fulfill the definition of lead-based paint inspection, in providing guidance on selecting building components of housing to sample and/or test them and the methods for determining whether they are coated with lead-based paint.

Astex Project No.: AE2620330 4

Lead Conclusions Based on the above EPA/HUD criteria and XRF testing, the following conclusions AND recommendation are offered:

~ Lead-Based Paint (LBP) identified as “positive” and Paint containing Lead (PCL) identified as “present” was determined to be on select surfaces.

~ While abatement is not mandated for non-residential facilities, OSHA regulations require protective measures for workers during disturbance of these materials.

~ All contractors performing work on-site are solely responsible for OSHA compliance, including the imple1mentation of site-specific Health and Safety Plans (HASPs) addressing lead exposure risks.

~ See XRF Analytical Results (Appendix A)

The Operational Safety and Health Administration (OSHA) does not recognize the EPA/HUD categorizations. Per OHSA’s Lead in Construction standard (29 CFR 1926.62) involving paints having any level of lead, employers/contractors involved in renovation or demolition must comply with the assessment measures and any applicable worker protections of the standard.

The enclosed analytical results have been reported to all of the above standards (EPA, HUD, OSHA).

o Readings at or above 1.0 mg/cm? are identified in red print in the XRF ANALYTICAL RESULTS - attached (Appendix A) with results listed as “Positive.”

~ Of the seventeen (17) readings, six (6) analyzed above 1.0 mg/cm’.

o Readings above 0.2 mg/cm? to 0.9 mg/cm? are identified in bold print in the XRF ANALYTICAL RESULTS- attached (Appendix A) with results listed as “Present.”

~ Of the seventeen (17) readings, six (6) analyzed > 0.2 mg/cm? to 0.9 mg/cm? and have lead present within the painted substrates.

o Readings 0.2 mg/cm? or less are reported as “Negative.”

~ Of the seventeen (17) readings, five (5) analyzed $< 0.2 mg/cm? and are considered to be non-lead-based paint containing.

~ It’s important to note that this building is not categorized as “target housing” and all renovation work that will impact Lead-Based Paint must be performed in accordance with the EPA: 40 CFR Part 74 Lead; Renovation, Repair, and Painting Program (RRP).

LEAD Recommendations No owner requirement from any regulatory entity requires lead painted material to be ‘abated’ prior to disturbance of said materials during the normal course of renovation and/or demolition tasks.

No owner requirement from any regulatory entity requires lead painted material to be ‘abated’ prior to disturbance of said materials during the normal course of renovation and/or demolition tasks.

The contractor(s) performing renovation and/or demolition tasks are solely responsible for OSHA compliance and administering their site-specific Health and Safety Plan(s) (HASPs) related to LBP and all other regulated materials (ORMs). This responsibility in no manner transfers to the owner, their authorized agent nor Astex.

Texas Environmental Lead Reduction Rules (TELRR) do not require LBP testing prior to demolition of structure(s) currently present. Furthermore, municipal permitting for the structure also does not require LBP testing.

If an employer is working with paint which contains any amount of lead, including those between 0.2 mg/cm? and 0.9 mg/cm?, in such a way that would generate airborne levels to which employees may be exposed, it is the employer's responsibility to conduct exposure monitoring (or use objective or historical data as defined in 29 CFR 1926.62(d)(3)(iii) through 1926.62(d)(3)(iv)(B) and in 29 CFR 1926.62(n)(4)) to demonstrate that the Lead in Construction standard's action level (30 micrograms/cubic meter of air) is not exceeded. The results of the exposure assessment then determine whether the employer would need to apply further protection of that rule. If the levels of lead to which employees are exposed are below the action level (which may occur when the levels of lead in paint are very low and work is being done in such a way as to not disturb the paint and, therefore, generate airborne concentrations of lead), then the further requirements of the standard would not apply.

Protection for workers per OSHA Regulations (29 CFR 1926.62) would be required during maintenance or renovation activities that may disturb materials identified to have paint containing lead present and is the sole responsibility of that specific contractor.

Resource Conservation and Recovery Act (RCRA) requires the demolition contractor to perform a TCLP (Toxicity Characteristic Leaching Procedure) waste characterization sample for landfill verification and RCRA assurances.

This process is solely the responsibility of the contractor conducting the haul-off of project related waste.

Section B: Limited Asbestos Survey

The following report presents the results of an asbestos survey conducted by Ms. Aracely Valdez, a Texas Department of State Health Services (TDSHS) licensed Asbestos Inspector, License No. 603996, at the aforementioned property. The survey was performed on June 26, 2026, during whicha total of twenty-seven (27) samples of suspect asbestos-containing building materials (ACBM) were collected. These samples were submitted to Environmental Analytical Services, LLC, located in Houston, Texas, a

TDSHS-licensed Asbestos PLM Laboratory (License No. 300373), for analysis using Polarized Light Microscopy (PLM) in accordance with EPA Method EPA/600/R-93/116.

This asbestos survey was conducted in accordance with the Texas Asbestos Health Protection Rules (TAHPR) as outlined in 25 Texas Administrative Code (TAC) §295.31- §295.73 and applicable federal regulations under the National Emission Standards for Hazardous Air Pollutants (NESHAP) 40 CFR Part 61, Subpart M. The purpose of this survey was to identify the presence, location, and approximate estimated quantity of ACBM prior to planned renovation, demolition, or maintenance activities, as required by state and federal law.

Asbestos is a naturally occurring group of fibrous minerals that were widely used in building materials and industrial products due to their durability, fire resistance, and insulating properties. Common applications included thermal insulation, flooring materials, roofing products, and textured coatings. However, inhalation of asbestos fibers has been linked to serious health risks, including asbestosis, lung cancer, and mesothelioma.

As a result, the use of asbestos in building products has been strictly regulated, and proper identification and management of ACBMs are required to prevent potential exposure during renovation or demolition activities.

A comprehensive inspection of all accessible areas of the structure was completed, with the collection of representative bulk samples of suspect materials in accordance with the sampling protocols set forth by the Environmental Protection Agency (EPA) in 40 CFR 763, Subpart E, also known as the Asbestos Hazard Emergency Response Act (AHERA) methodology. All collected samples were analyzed by a National Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratory using PLM with dispersion staining.

Asbestos Conclusions and Recommendations To support informed decision-making and regulatory compliance, the following conclusions and recommendations are offered based on laboratory results and site observations.

1. The results of the laboratory analysis confirm the presence of ACM in the following locations (including all similar and visually consistent materials identified elsewhere throughout the project site):

e The Black Tar Mastic on the Bench located in the Men’s Shower Room.

e The 6-inch Transite Pipe located in the Men’s Shower Room.

2. Materials identified as containing greater than 1% asbestos are classified as ACBM in accordance with TAHPR and NESHAP definitions. Any identified ACBM must be managed, handled, or abated (if to be disturbed) in strict compliance with applicable regulatory requirements, and any disturbance or removal must be performed by a licensed asbestos abatement contractor under the oversight of a licensed asbestos consultant (i.e., Astex Environmental Services).

3. This asbestos survey fulfills the regulatory requirements for public buildings in the State of Texas prior to any renovation or demolition activities, as mandated by TAHPR and NESHAP. This report must be provided to all contractors and relevant parties involved in the project to ensure the safe and legal handling of any ACBM.

Failure to comply with these requirements may result in regulatory enforcement actions and penalties.

Limitations: The results, findings, and conclusions documented in this report are based solely on the conditions observed at the subject property on the date(s) of the inspection.

Astex Environmental Services (Astex), and its representatives make no representations or warranties regarding the past, present, or future condition of the premises or building materials beyond what was observed and sampled at the time of inspection. The asbestos survey and sampling included the areas identified and authorized by those requesting the work and focused on building materials that may be impacted by future maintenance, renovation, or demolition activities. Additional suspect materials may exist in areas that were inaccessible, concealed, or outside the defined scope of this inspection.

Section C: PCBs

Polychlorinated biphenyls (PCBs), originally termed "chlorinated biphenyl’s," were commercially produced as complex mixtures containing multiple isomers at different degrees of chlorination. In the United States, commercial production of PCBs was taken over in 1929 by Monsanto Company from Swann Chemical Company. Manufacturing levels increased in response to the electrical industry's need for a "safer" (than flammable mineral oil) cooling and insulating fluid for industrial transformers and capacitors. PCBs were also commonly used as stabilizing additives in the manufacture of flexible PVC coatings for electrical wiring and electronic components to enhance the heat and fire resistance of the PVC.

PCBs were used as coolants and insulating fluids (transformer oil) for transformers and capacitors, especially in components of early fluorescent light fittings and electrical transformers, and as plasticizers in paints and cements, stabilizing additives in flexible PVC coatings of electrical wiring and electronic components, pesticide extenders, cutting oils, reactive flame retardants, lubricating oils, hydraulic fluids, and sealants (for caulking in schools and commercial buildings), adhesives, wood floor finishes (such as Fabulon and other products of Halowax in the U.S.), paints, de-dusting agents, water-proofing compounds, casting agents, vacuum pump fluids, fixatives in microscopy, surgical implants, and in carbonless copy ("NCR") paper. PCB congeners are odorless, tasteless, clear to pale-yellow, viscous liquids (highly chlorinated mixtures are more viscous and deeper yellow). They are formed by electrophilic chlorination of bipheny! with chlorine gas.

PCBs are very stable compounds and do not decompose readily. Their destruction by chemical, thermal, and biochemical processes is extremely difficult, and presents the risk of generating extremely toxic dibenzodioxins and dibenzofurans through partial oxidation.

Intentional degradation as a treatment of unwanted PCBs generally requires high heat or catalysis.

On the date of the inspection (June 26, 2026), fluorescent lights were identified on sight. The dismantling of these lights to reveal the labeling of the transformers will identify the use of PCBs in these products. Contractors removing these fixtures must make that determination prior to disposal and treat the waste materials accordingly.

Section D: MERCURY (Hg)

Mercury (Hg) has many industrial uses and applications. Upon inspection you will find that it is present in several items commonly found in commercial buildings. Most mercury compounds are also toxic and readily absorbed and accumulated by the body. Some common building components and items which contain elemental mercury include thermometers, barometers, switches, thermostats, flowmeters, and laboratory reagents (e.g., mercuric salts and oxides), pesticides, paints and stains, batteries, and fluorescent lamps.

Elemental mercury (Hg) is a volatile toxic heavy metal. Mercury is an unusual metal in that it can evaporate at room temperature. Also, mercury is a neurotoxin which means it can adversely affect the central nervous system. Upon exposure, mercury tends to accumulate quickly in the brain where it tightly binds with the tissue and is released at a very slow rate. In addition, inorganic and organic mercuric compounds are also commonly found in structures. Mercuric compounds can pose the following types of health hazards:

toxic to lethal via ingestion or absorption, toxic to the following organs or systems: central nervous system, digestive system, kidney, liver, and skin. Because mercury and its compounds tend to be readily absorbed and accumulated by the body, it is imperative to identify potential sources of mercury within the building as well as potential activities that could result in the release and exposure to these materials. Due to the pervasiveness of mercury and its compounds in the construction of building materials (e.g., thermostats and fluorescent lights) total elimination is not possible. However, the wisest strategy appears to be that of identification and elimination where possible. Where replacement and elimination is not possible, then efforts should be taken to minimize the risk of release of these materials as well as establishing a contingency plan for properly handling any releases that may occur. If proper spill response is not initiated, then these materials can pose a long-term health hazard to building occupants. The final component would be establishing policies and procedures for promoting the proper recycling and disposal of mercury and its compounds in order to prevent its release to the environment and to promote compliance with state and federal Universal Waste Disposal requirements.

On the date of the inspection (June 26, 2026), no noteworthy building materials containing Hg were identified.

BACKGROUND INFORMATION

EVALUATION DATA SOURCE AND DATE:

This sheet is supplemental information to be used in conjunction with Chapter 7 of the HUD Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing, 2012 Edition ("HUD Guidelines"). Performance parameters shown on this sheet are calculated using test results on building components in the HUD archive.

Testing was conducted on 146 test samples in January 2020 and January 2021, with four separate instruments running software version Pb200i 5.0 (DEBUG version) in Action Level test mode. The actual source strength of each instrument in 2020 was approximately 2.9 mCi; source ages were approximately 9 months. The 2021 sources were new with source strength 5 mC1.

OPERATING PARAMETERS

Performance parameters shown in this sheet are applicable only when properly operating the instrument using the manufacturer's instructions and procedures described in Chapter 7 of the HUD Guidelines.

XRF CALIBRATION CHECK:

The calibration of the XRF instrument should be checked with the Action Level set to 1.0 mg/cm? using the paint film nearest 1.0 mg/cm? in the NIST Standard Reference Material (SRM) used (e.g., for NIST SRM 2579, use the

1.02 mg/cm? film; for NIST SRM 2579a, use the 1.04 mg/cm? film).

If the average (rounded to 1 decimal place) of three readings is outside the acceptable calibration check range, follow the manufacturer's instructions to bring the instrument into control before XRF testing proceeds.

EVALUATING THE QUALITY OF XRF TESTING:

Randomly select ten testing combinations for retesting from each house or from two randomly selected units in multifamily housing.

Conduct XRF re-testing at the ten testing combinations selected for retesting.

Determine if the XRF testing in the units or house passedor failed the test by applying the steps below. Compute the Retest Tolerance Limit by the following steps:

Determine XRF results for the original and retest XRF readings. In single-family and multi-family housing, a result is defined as a single reading. Therefore, there will be ten original and ten retest XRF results for each house or for the two selected units.

Calculate the average of the original XRF result and the retest XRF result for each testing combination.

Square the average for each testing combination.

Add the ten squared averages together. Call this quantity C.

Multiply the number C by 0.0072. Call this quantity D.

Add the number 0.032 to D. Call this quantity E.

Take the square root of E. Call this quantity F.

Multiply F by 1.645. The result is the Retest Tolerance Limit.

Compute the average of all ten original XRF readings.

Compute the average of all ten re-test XRF readings.

Find the absolute difference of the two averages.

Viken Detection Pb200i PCS September 2022 Action Level: 0.5 mg/cm?

If the difference is less than the Retest Tolerance Limit, the inspection has passed the retest. If the difference of the overall averages equals or exceeds the Retest Tolerance Limit, this procedure should be repeated with ten new testing combinations. If the difference of the overall averages is equal to or greater than the Retest Tolerance Limit a second time, then the inspection should be considered deficient.

Use of this procedure is estimated to produce a spurious result approximately 1% of the time. That is, results of this procedure will call for further examination when no examination is warranted in approximately 1 out of 100 dwelling units tested.

TESTING TIMES:

The nominal reading time recorded in Archive tests averaged 5.39 seconds in fixed time mode and 2.67 seconds in variable-time mode. Nominal reading time means the time the instrument’s shutter is open when the §’Co source’is new. Actual reading time depends on the age of the source. Since 5’Co has a half-life of approximately 9 months, reading time doubles for every 9 months of source age.

CLASSIFICATION OF RESULTS:

XRF results are classified as positive if they are greater than or equal to 0.6 mg/cm?, negative if they are jess than or equal to 0.4 mg/cm? and inconclusive if they are equal to 0.5 mg/ cm?.

DOCUMENTATION:

This XRF Performance Characteristic Sheet (PCS) was developed by QuanTech, inc., under a contract with the U.S. Department of Housing and Urban Development, Office of Lead Hazard Control and Healthy Homes.

A report titled Methodology for XRF Performance Characteristic Sheets (EPA 747-R-95-008) provides an explanation of the statistical methodology used to develop Performance Characteristic Sheets at the Federal standard (Action Level) of 1.0 mg/cm?2, and provides empirical results from using the recommended inconclusive ranges or thresholds for specific XRF instruments. The report may be downloaded at http:/Avww2.epa.gov/lead/methodology-xrf-performance-characteristic-sheets-epa-747-r-95-008-september- 1997. The methodology was subsequently generalized by QuanTech for application to other Action Levels.
