1.0 INTRODUCTION

This report documents the methods and findings of the NESHAP Pre-Renovation Asbestos Survey for the Bermingham VA Health Care System (Mechanical Rooms), located at 700 South 19th Street in Birmingham, Alabama.

1.1 Scope of Work

The purpose of the survey was to locate, identify, sample, and assess the condition of building materials suspected of containing greater than one percent (>1%) asbestos.

The survey was performed on October 8, 2024 by Charles Yoon, of AEI, an Alabama certified asbestos inspector (Certificate No. AIN1222B1CE4008, Expiration Date: November 14, 2025).

Inspector Certifications are provided as Appendix A to this report. The asbestos inspection was performed in conformance with modified protocols set forth by the Environmental Protection Agency (EPA) Asbestos Hazard Emergency Response Act (AHERA), and the National Emission Standards for Hazardous Air Pollutants (NESHAP) and in accordance with state regulations.

1.2 Site Specific Survey Limitations

The data presented and the opinions expressed in this report are qualified as follows:

• The sole purpose of the investigation and of this report was to assess the Site with respect to asbestos materials as defined in AEI’s Scope of Work and the applicable State, Federal and local environmental laws and regulations.

• The Scope of Services was defined by the requests of the Client, the time and budgetary constraints imposed by the Client, and the availability of access to the Site.

• The collection of bulk building material samples for analysis is a destructive procedure and may cause damage to the integrity of building systems. AEI took normal precautions to minimize damage, however, AEI will not be held responsible for damage to the building systems as a result of sample collection.

1.3 NESHAP Regulations and Guidelines

The Code of Federal Regulations (CFR), 40 CFR 61, Subpart M, NESHAP, classifies asbestos-containing material (ACM) as any material or product that contains greater than one percent (>1%) asbestos. As ACM is identified, it is classified as either friable or non-friable.

Friable materials are more hazardous than non-friable materials since they are more likely to release fibers into the air. Friable is defined as any ACM that when dry, can be crumbled, pulverized, or reduced to powder by hand pressure. Non-friable ACM is classified as either Category 1 or Category 2 material as follows:

• Category 1 – Asbestos containing packings, gaskets, resilient floor coverings (including associated floor mastic) and asphalt roofing products; and

• Category 2 – All remaining types of non-friable asbestos containing material not included in Category 1 that when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure.

Regulated asbestos containing materials (RACM), a hazardous waste when friable, is classified as any manufactured material that contains greater than one percent (>1%) asbestos and is:

1. Friable – The material can be crumbled, pulverized, or reduced to powder by hand pressure.

2. Category 1 that are subjected to sanding, grinding, cutting, or abrading.

3. Category 1 material that has become friable during renovation activities: or

4. Category 2 material that has become friable during renovation activities.

Materials containing greater than 1% asbestos are subject to the NESHAP regulations (40 CFR Part 61, Subpart M). RACM (friable ACM and non-friable ACM that will become friable during renovation/demolition operations) must be removed from structures prior to renovations or demolitions. Certain non-friable ACM and materials containing one percent or less (≤1%) asbestos may remain in structures during renovations/demolitions.

2.0 SITE DESCRIPTION

The site consisted of two mechanical rooms and associated crawl space and roof within a twelve-story medical building, reportedly constructed in 1949. The interior finishing comprised suspected gypsum board wall with joint compound, vinyl floor tile with associated mastic, ceramic floor tile with associated grout, pipe insulations, gypsum wallboard cavity insulation, cove base with associated mastic, concrete masonry unit (CMU) and brick perimeter walls, and bare concrete floor. Thermal system insulation (TSI) which appeared to be fiberglass material was present on pipe runs. The roof finishing comprised of asphalt rolled roofing and associated mastic.

Select Photographs of the Site and identified suspect building materials are included as Appendix B to this report.

3.0 METHODOLOGY

3.1 Material Sampling or Investigation

3.1.1 Asbestos Sampling Procedures

During the survey, AEI visually inspected all readily accessible areas of the subject property and identified homogeneous areas of suspect material (materials that share the same texture, color, use, and appear to have been applied at approximately the same time) and collected representative samples of suspect material for laboratory analysis. The samples collected were placed in plastic bags, sealed, labeled, and transported under chain of custody documentation to an accredited laboratory.

A representative number of samples were collected for each Homogeneous Area in accordance with the following:

The following are the Homogeneous Application symbols which were used for identification during the survey:

T = Thermal System Insulation

M = Miscellaneous Materials

S = Surfacing Materials (Troweled or Spray-Applied)

The minimum number of samples collected and analyzed for each homogeneous material was as specified in the following table. This table was developed based on the AHERA Sampling Protocol (40 CFR 763.86).

Homogeneous Material Type Number of Samples

Surfacing Materials Up to 1,000 sq. ft. – 3 Samples 1,001 – 5,000 sq. ft. – 5 Samples 5,001 – 10,000 sq. ft. – 7 Samples Over 10,000 sq. ft. – Minimum 9 Samples

Thermal Systems Insulation Minimum 3 Samples/Material Type

Miscellaneous Materials Minimum 3 Samples/Material Type

Patch Materials Minimum 2 Samples

Previously Sampled Materials Accepted Positive Sample without Further Collection (Inspector Discretion)

Note: Exceptions to numbers of samples may be made at the discretion of the Inspector (typically for materials with limited quantities).

Bulk material samples were collected in 4-mil plastic bags, or through the use of sample coring devices in sealed plastic tubes and sealed for transport to the laboratory. Each sample collected was assigned its own unique coded number. Samples were collected, analyzed, and stored under strict chain-of-custody protocol.

AEI’s approach included a visual assessment of the spaces to locate, as far as practicable, suspect ACM in interior and exterior building or structure locations. Suspect materials were divided into "Homogeneous Areas", building materials which were determined by the inspector to be similar based on their color, texture, and age. In addition, Homogeneous Areas were identified in some cases by function or use, by size, or area/location of the material as well as color, texture, and age or type of material.

AEI collected a total of forty-one (41) bulk suspect asbestos-containing building material samples from the Site which layered out to eighty-four (84) samples during laboratory analysis.

Mechanical and electrical equipment including, but not limited to, boilers, HVAC units, refrigeration units, etc. may have internal parts that are asbestos containing. In some cases, these materials where applicable were assumed to contain asbestos where no prior information related to sampling of these materials was provided or due to the inaccessible nature of the materials for sampling. Prior to renovation or demolition, internal components should be inspected or assumed to contain asbestos.

3.2 Analytical Methods

All samples collected were transported under Chain of Custody documentation to EMLab P&K, LLC in Norcross, Georgia for analysis. EMLab P&K is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP #201060-0). Laboratory certifications are provided as Appendix C of this report.

3.2.1 Asbestos Analysis

All bulk suspect asbestos samples were analyzed using polarized light microscopy (PLM) in accordance with the EPA “Method of Determination of Asbestos in Bulk Samples” (EPA 600/R- 93/116, July 1993). This method is referred to as the “Improved Method” and is recommended by EPA as a preferred substitute to the Interim Method EPA 600/M4-82-020, 1982. The laboratory analytical report is included as Appendix D to this report. It should be noted that some materials are multi-layered and are inseparable during the bulk sample collection process.

Each layer requires specific analysis and reporting by layer (each layer = 1 sample analysis).

In accordance with U.S. EPA guidelines, samples are categorized into “homogeneous groups” by material type. The number of samples to be taken for each group is dictated by the type and quantity of the material. All samples within the homogeneous group must be one percent or less (≤1%) asbestos in order to classify the material as “non-asbestos”. Conversely, the positive result of any single (1) sample dictates that the Homogeneous Group be classified as ACM. Limitations and Service Constraints

• AEI was granted full access within the subject property. Discrete sampling procedures were utilized on request of the client. Access to the two mechanical rooms and associated crawl space and roof was granted by the property management.

• Due to the hidden nature of some building materials, AEI attempted to access suspect materials for sampling through limited destructive inspection methods.

• The inspection of every space or void (inside walls, ceilings, chases, etc.) within a building structure is not feasible or cost effective. Therefore, reasonable attempts were made to investigate a representative number of locations, which allowed for assumptions to be made regarding typical construction of the investigated building/areas.

• Where concrete substrates were encountered below floor finishes or behind wall finishes, they were considered to be the lowest flooring substrate or outer wall substrate. No coring through identified concrete substrates was performed as part of this survey.

• Where carpeting or other floor coverings exist, AEI attempts to determine substrates or other suspect asbestos-containing flooring materials which may have been covered.

However, without removing all carpeting or other flooring materials from a facility, it cannot be guaranteed that other layers of flooring materials do not exist. Should materials be identified under carpets or other flooring materials during a renovation or demolition activity they should be sampled and analyzed to determine asbestos content prior to disturbance or removal.

• Mechanical and electrical equipment including, but not limited to, boilers, HVAC units, refrigeration units, etc. may have internal parts that are asbestos-containing. No investigation inside equipment was performed.

• An inspection below grade on the building foundation or other Site areas was not performed as part of AEI’s scope of work.

• AEI derived the data in this report primarily from visual inspections, interviews with individuals with information about the Site and a limited number of environmental samples. The passage of time, manifestation of latent conditions, or occurrence of future events may require further exploration at the Site, analysis of the data, and re-evaluation of the findings, observations, conclusions, and recommendations expressed in the report.

• In preparing this report, AEI has relied upon and presumed accurate certain information (or absence thereof) about the Site provided by the Client, and others identified herein.

Except as otherwise stated in the report, AEI has not attempted to verify the accuracy or completeness of such information.

• The data reported and the findings, observations, conclusions, and recommendations expressed in the report are limited by the Scope of Services, including the extent of environmental sampling and other tests.

• Asbestos surveys are considered destructive in that the collection of multiple bulk building material samples must be performed for subsequent laboratory analysis and may cause damage to the integrity of building systems. Multiple samples of each suspect building material are collected utilizing hand tools via chipping, cutting, gouging, coring, or scraping. Samples may vary in size depending upon the type of material(s) being collected and the location of the material. Larger samples are sometimes required to access layered materials (i.e., multiple layers of flooring or roofing). Repairs via patching will only be performed for friable thermal insulation materials. AEI took normal precautions to minimize damage, however, AEI will not be responsible for the minor damage caused by sampling of suspect building materials.

5.0 SUMMARY AND RECOMMENDATIONS

This report documents the methods and findings of the NESHAP Pre-Renovation Asbestos Survey for the Bermingham VA Health Care System (Mechanical Rooms), located at 700 South 19th Street in Birmingham, Alabama.

5.1 Summary of Findings

Based upon the laboratory analytical results, the sampled materials did not identify the presence of asbestos in any of the building materials sampled.

5.2 Recommendations

Based on the results of the Pre-Renovation Asbestos Survey Report, AEI makes the following recommendations:

1. Should the scope of the renovation be altered from the original plans, AEI recommends that the areas and/or materials not investigated as part of this inspection including the roofs and any remaining hotel rooms be surveyed by an EPA certified asbestos inspector.

2. If suspect materials that are not referenced in this report are identified during renovation/demolition activities, regulations require, and AEI recommends that the materials be sampled and analyzed to confirm or deny the presence of asbestos prior to disturbance of the materials.

3. Where carpeting or other floor coverings exist, AEI attempts to determine substrates or other suspect asbestos-containing flooring materials which may have been covered.

However, without removing all carpeting or other flooring materials from a facility, it cannot be guaranteed that other layers of flooring materials do not exist. Should materials be identified under carpets or other flooring materials during a renovation or demolition activity they should be sampled and analyzed to determine asbestos content prior to disturbance or removal.

4. An inspection below grade on the building foundation was not performed as part of our scope of work. Prior to disturbance, all building foundations should be inspected for suspect waterproofing materials or other suspect materials.

All components not quantified as asbestos content and non-asbestos content are considered to be non-fibrous matrix components. Matrix components may include, but are not limited to, gypsum, paint, silicate minerals, vinyl, binder, calcium carbonate, tar, and foam.

Inhomogeneous samples are separated into homogeneous subsamples and analyzed individually. ND means no fibers were detected. When detected, the minimum detection and reporting limit is less than 1% unless point counting is performed. Floor tile samples may contain large amounts of interference material and it is recommended that the sample be analyzed by gravimetric point count analysis to lower the detection limit and to aid in asbestos identification.
