This document is an Asbestos Containing Building Materials (ACBM) Inspection Report for Buildings #223 and #224 located at USAG Fort Buchanan in Guaynabo, Puerto Rico, conducted by Zimmetry Environmental Management Corp. on June 24, 2025. The comprehensive inspection involved evaluating interior and exterior areas of the buildings, with laboratory analysis performed by Eurofins using Polarized Light Microscopy (PLM) to identify potential asbestos-containing materials.

The laboratory testing revealed asbestos-containing materials specifically in vinyl tile associated mastic for Building 223, with two samples (25187-223-01 and 25187-223-02) showing 3% Chrysotile asbestos in the black mastic layer. No asbestos was detected in Building 224's samples. The report recommends that if these materials are to be removed, they must be managed and disposed of by a licensed asbestos contractor in an approved asbestos landfill site, following EPA and OSHA regulations. The inspection was conducted by certified environmental asbestos inspectors Miguel A. Peña and Alicia García, with samples collected from various areas including floor tiles, adhesives, drywall, and ceiling tiles.

Section 1: Executive Summary

1.1 Introduction

An Asbestos Containing Building Materials (ACBM) inspection was conducted on June 24, 2025, at the Buildings #223 & #224 located at USAG Fort Buchanan, in the municipality of Guaynabo, Puerto Rico. The asbestos-containing building materials sampling was performed to identify materials that contain asbestos fibers above allowable levels and to assist with compliance with local, state, and federal regulations.

1.2 Summary of Property Evaluation

The inspection consisted of the evaluation of the interior and exterior areas of the buildings mentioned above. The analytical report found that asbestos fibers were present in selective materials. For specific locations and additional details on the location of ACBM, reference Sections 2 and 3. If suspected components and surfaces not previously evaluated are identified in the facilities, they shall be considered to contain asbestos until the appropriate analysis is performed.

1.3 Property Locations of Building Components with Asbestos

Table 1-1 summarizes the buildings components containing asbestos fibers. Details that identify positive asbestos findings within specific areas and on surfaces were provided in the Asbestos Sampling Inspection Report, Section 2. The quantification of positive materials in Table 1-1 is only an estimate. If an abatement of the materials is conducted, the Contractors shall estimate the amount to be abated. If homogeneous materials not accounted for are identified in areas not described in this Report, they shall be managed as asbestos-containing material.

Note:

1. The quantification of positive materials presented in this table is only an estimate. If an abatement of the materials will be conducted, the Contractors shall estimate the amount of materials to be abated.

Section 2: Asbestos Containing Building Materials Inspection Report

2.1 Overview of the Evaluation

This ACBM inspection is an evaluation to identify the location of material containing asbestos that exists within. Our scope of work services for this project consisted of the following tasks.

• A walk-through and observation of the site was performed.

• Bulk sampling of Suspected ACBM within the structure.

• Polarized Light Microscopy (PLM) Analysis of bulk samples.

• Final Inspection Report.

Throughout the inspection, the following suspected ACBM were observed and sampled:

• Ceiling Tile • Joint Compound

• Cove Base Adhesive • Vinyl Tiles

• Drywall Panel • Window Caulk

The sampling was conducted by the Department of Natural and Environmental Resources (DRNA) of Puerto Rico and the United States Environmental Protection Agency (USEPA) accredited Inspectors qualified by experience, education, and training in recognition of potential ACBM and approved bulk sampling techniques. Direct access may have been restricted in certain areas due to physical hazards. In these cases, if any, assumptions were made based on findings from other locations whenever possible. Any such assumptions are duly noted in this report.

The inspection followed the Environmental Protection Agency recommended procedures EPA- 450/2-78-014 (Parts I and II), EPA 560/5-85-024, and 40 CFR 763. These procedures call for the visual inspection of the building for suspect friable material and the collection and analysis of representative samples of suspect material.

2.2 Sampling Procedure and Results Presentation

The bulk sampling procedures utilized for the collection of the ACBM required the establishment of homogeneous sampling areas. A homogeneous sampling area is defined as an area of friable or non-friable material of a similar type that appears to be applied or constructed during the same time.

Samples collected from these predetermined homogeneous sampling areas were labeled and transported for analysis. Sample locations were identified by their current use or functional space name. Each type of asbestos displays a unique property when subject to PLM. Properties are unique to crystalline asbestos form and, therefore, can be used to identify the type of asbestos mineral as chrysotile, amosite, crocidolite, anthophyllite, tremolite, and actinolite.

The percentage of each asbestos mineral type is determined by visual estimation, which is done by mixing the sample thoroughly to provide a more accurate percentage. Any material containing over one percentage (>1%) by weight of any asbestos mineral form is considered by the USEPA to be asbestos-containing material. If disturbed, it must be handled according to specific State and Federal Regulations.

Thirty-Six (36) samples of suspected materials were collected. It is our opinion that an acceptable minimum number of critical areas were sampled in keeping with the homogeneous nature of much of the material that was observed. Non-destructive sampling techniques were used. If they exist, walls, ceilings, columns, and other inaccessible areas were not broken into. It should be noted that these inaccessible areas may contain ACBM, which was not observed during the inspection. Any future construction or renovation should anticipate the presence of these materials.

The samples were received and analyzed by Eurofins Atlanta in Atlanta, GA (Certified Proficient by the National Institute of Standards and Technology (NIST) NVLAP program for bulk sample asbestos analysis; Laboratory Id 102082-0). The analysis method was polarized light microscopy with dispersion staining, as recommended by the US EPA. This survey focused on the building materials, which are present throughout the interior and exterior of the building structure.

2.3 Findings and Recommendations

2.3.1 Introduction

This section describes the asbestos-containing building materials (ACBM) observed in the inspection. Please note that the recommendations given are the minimum required action, which should be taken based on our professional judgment.

There was one type of Asbestos Containing Building Materials found within the evaluated buildings:

• Vinyl Tile Associated Mastic

If this material is to be removed, they should be managed and disposed of by a licensed asbestos contractor and disposed of as contaminated waste in an approved asbestos landfill site.

2.3.2 Specific Findings

The following ACBM was found to contain more than one percent (1%) of asbestos by weight and are listed according to their homogeneous area:

1. Vinyl Tile Associated Mastic Samples: 25187-223-01 & 25187-223-02

These materials are in a non-friable condition, and the analytical result range is 3% Chrysotile asbestos.

2.3.3 Homogeneous Areas with Special Considerations

2.3.5 Inaccessible Areas

2.4 Conditions and Limitations—Disclaimer

Zimmetry Environmental Management Corp. has performed this asbestos-containing building materials inspection thoroughly and professionally, consistent with commonly accepted industry standards. The Preparer cannot guarantee and does not warrant that this evaluation has identified all adverse environmental factors and/or conditions affecting these buildings on the date of the evaluation. If suspected materials are identified, they shall be managed as containing asbestos until the appropriate laboratory analysis is performed. The quantification of positive materials in Table 1-1 is only an estimate. If an abatement of the materials is conducted, the Contractors shall estimate the amount to be abated.

The results reported, and conclusions reached by the Preparer are solely for the benefit of the Owner and occupants. The results and opinions in this report, based solely on the conditions found at the buildings on the date of the evaluation, are valid only on that date. The Preparer assumes no obligation to advise the client of any changes in any actual or potential asbestos hazards at these buildings beyond the date of the evaluation.

2.5 Abatement Conditions

The US Environmental Protection Agency rules concerning the application, removal, and disposal of Asbestos Containing Building Materials (ACBM) were issued under the asbestos NESHAP (U.S. EPA National Emission Standards of Hazardous Air Pollutants, 40 CFR 61 Subpart M, October 30, 1987). The asbestos N.E.S.H.A.P. regulation governs asbestos demolition and renovation projects in all facilities. The NESHAP rule usually requires owners or operators to have all friable ACBM removed before a building is demolished, and it may require removal before a renovation. The Department of Natural and Environmental Resources (DRNA) of Puerto Rico requires inspecting the presence of asbestos-containing materials before building demolition.

If the identified materials are to be removed, they shall be managed following the work practices and procedures for the removal and disposal of asbestos-containing materials by a licensed asbestos contractor and disposed of as contaminated waste in an approved asbestos landfill site.

The Contractor shall comply with all the Department of Natural and Environmental Resources (DRNA) of Puerto Rico requirements. The Contractor has to submit the abatement work plan to the DRNA for approval. The asbestos abatement is classified as Class II for the miscellaneous materials by OSHA, which includes the abatement, packing, and storage of asbestos. The abatement has to be performed without damaging any structure or adjacent area and protecting the safety and health of the employees and the general public.

Due to the limitations of the EPA 600 / R93 / 116 method, nonfriable organically bound materials (NOBs) such as vinyl floor tiles can be difficult to analyze via polarized light microscopy (PLM). EPA recommends that all NOBs analyzed by PLM, and found not to contain asbestos, be further analyzed by Transmission Electron Microscopy (TEM). Please note that PLM analysis of dust and soil samples for asbestos is not covered under NVLAP accreditation. Estimated measurement of uncertainty is available on request.

Dear Andres, Enclosed are asbestos analysis results for PLM Bulk samples received at our laboratory on June 26, 2025. The samples were analyzed for asbestos using polarizing light microscopy (PLM) per the EPA 600/R-93/116: Method for the Determination of Asbestos in Bulk Building Materials and EPA 40 CFR Appendix E to Subpart E of Part 763: Interim Method of the Determination of Asbestos in Bulk Insulation Samples.

Sample results containing >1% asbestos are considered asbestos-containing materials (ACMs) per EPA regulatory requirements. The detection limit for the EPA 600 Method is <1% by calibrated visual estimate.

Thank you for your business and we look forward to continuing good relations.

Kind Regards, Dana Till, QA Manager

Due to the limitations of the EPA 600 / R93 / 116 method, nonfriable organically bound materials (NOBs) such as vinyl floor tiles can be difficult to analyze via polarized light microscopy (PLM). EPA recommends that all NOBs analyzed by PLM, and found not to contain asbestos, be further analyzed by Transmission Electron Microscopy (TEM). Please note that PLM analysis of dust and soil samples for asbestos is not covered under NVLAP accreditation. Estimated measurement of uncertainty is available on request.
