Limited Asbestos Inspection Report Building 259

Jacksonville, Arkansas 72078

Safety & Environmental Investigations, (SEI) Inc. was retained by the Little Rock Air Force Base in Jacksonville, Arkansas to perform a limited pre-renovation asbestos inspection of the flooring in the packing bay of Building 259 located on the Little Rock Air Force Base, Jacksonville, Arkansas. On August 24th, 2023, Mr. Joshua Roberson (Certification #015183) of SEI, Inc. (License #000260) performed the on-site inspection and sampling of the structure for the presence of suspect asbestos-containing materials.

The inspection was performed following EPA AHERA guidelines (40 CFR 763) and NESHAP (40 CFR 61, Subpart M) and the Arkansas Department of Entergy and Environment, DEQ, Regulation 21.

Background

The structure is a single-story metal framed structure with a pitched, metal roof set on a concrete slab foundation. The interior finishes of the structure included fiberglass batt insulation, sheet rock walls and various floor coverings throughout the Packing Bay of the Structure. The structure was occupied and in good condition at the time of the inspection. The date of construction was unknown and according to the client, the structure is scheduled for future renovations to the flooring throughout the Packing Bay only.

Purpose of Study

The purpose of this study was to identify and collect samples of suspect asbestos-containing materials from the structure for laboratory analysis. At the client’s request, an inspection for the presence of suspect asbestos-containing materials was performed of the flooring in the packing bay of the structure.

Sampling was performed in accordance with guidelines published in the Asbestos Hazard Emergency Response Act (AHERA), 40 CFR Part 763. Suspect asbestos-containing materials were divided into three different categories: surfacing, thermal system insulation, and miscellaneous materials. Each category of materials was divided into homogeneous areas, which are defined as materials similar in appearance, color, texture, and installation date. Samples were collected from each homogeneous area according to the following scale:

Surfacing Materials: <1000 sq. ft. 3 Samples

1,000 – 5,000 sq. ft. 5 Samples >5,000 sq. ft. 7 Samples Thermal System Insulation any amount 3 Samples Minimum Miscellaneous Materials any amount 2 Samples Minimum

Building 259 SEI Job # 23125 Page 4

The Environmental Protection Agency defines an asbestos-containing material as any material which contains greater than one percent (1%) asbestos by weight. The entire homogeneous area is classified as asbestos-containing if any one (1) of the samples collected from that area is found to contain more than 1% asbestos. All samples collected from a homogeneous material must reveal a result of one (1) percent asbestos or less for a material to be considered non-asbestos containing.

The condition of suspect homogeneous areas was assessed to determine if the materials were friable (RACM) or non-friable. Friable materials (RACM) are materials that when dry can be crumbled, pulverized, or reduced to powder by hand pressure. Non-Friable materials are materials that cannot be crumbled, pulverized, or reduced to powder by hand pressure when dry. Non-Friable materials are divided into two categories, Category I Non-Friable materials, (asbestos-containing packing, gaskets, resilient floor coverings, and asphalt roofing products that contain >1% asbestos), and Category II Non-Friable materials (any material, excluding category I non-friable ACM, containing >1% asbestos that cannot be crumbled, pulverized, or reduced to powder by hand pressure).

Asbestos samples were analyzed via Polarized Light Microscopy utilizing EPA Method 600/R-93/116 by Crisp Analytical, LLC in Carrollton, Texas. CA Labs is accredited by the National Institute for Standards and Testing, National Voluntary Laboratory Accreditation Program for Bulk Asbestos Analysis (NVLAP Air and Bulk #200349-0). It should be noted EPA NESHAPS recommends point-counting of positive asbestos results revealing less than 10% asbestos content by visual estimation.

Findings

The following table provides a summary of the suspect asbestos-containing materials sampled from the structure, along with the analytical results and locations of the materials.

Asbestos samples were collected from materials identified as Homogeneous Materials based upon visual inspection of the site. SEI, Inc. is not responsible for assumptions on homogeneity which prove to be incorrect. In addition, samples collected represent only that portion of the entire homogeneous material. SEI, Inc. is not responsible for materials not identified and sampled due to the restraints on accessibility of the material. No warranties, expressed or implied, relate to the previous and/or future conditions.

During any operations involving renovation or demolition, suspect asbestos materials may be encountered which were not identified in this inspection. Work should immediately cease, and a certified inspector contacted for further sampling to identify those additional materials.

Asbestos Analysis was performed by Crisp Analytical, LLC in Carrollton, Texas. CA Labs is solely responsible for all asbestos analytical results contained in and referred to in this report.

Summary of polarized light microscopy (PLM / Stereomicroscopy bulk asbestos analysis) using the methods described in 40CFR Part 763

Appendix E to Subpart E (Interim and EPA 600 / R-93 / 116 (Improved). The sample is first viewed with the aid of a stereomicroscope. Numerous liquid slide preparations are created for analysis under the polarized microscope where identifications and quantifications are preformed. Calibrated liquid refractive oils are used as liquid mouting medium. These oils are used for identification (dispersion staining). A calibrated visual estimation is reported, should any asbestiform mineral be present. Other techniques such as acid washing are used in conjugation with refractive oils for detection of smaller quantities of asbestos. All asbestos percentages are based on calibrated visual estimation traceable to NIST standards for regulated asbestos. Traceability to measurement and calibration is achieved by using known amounts and types of asbestos from standards where analyst and laboratory accuracy are measured. As little as 0.001% asbestos can be detected in favorable samples, while detection in unfavorable samples may approach the detection limit of 0.50% (well above the laboratory definition of trace).

Vermiculite containing samples may contain trace amounts of actinolite/tremolite. When not detected by PLM, these samples should be analyzed using TEM methods and / or water separation techniques. Suspected actinolite/vermiculite presence will be indicated through the sample comment section of this report.

Fibrous talc containing samples may contain a regulated asbestos fiber known as anthophyllite. Under certain conditions the same fiber may actually contain both talc and anthophyllite (a phenomenon called intergrowth). Again, TEM detection methods are recommended. CA Labs PLM report comments will denote suspected amounts of asbestiform anthophyllite with talc, where further analysis is recommended.

Some samples (floor tiles, surfacings, etc.) may contain fibers too small to be detectable by PLM analysis and should be analyzed by TEM bulk protocols.

A "trace asbestos" will be reported if the analyst observes far less than 1% asbestos. CA Labs defines "trace asbestos" as a few fibers detected by the analyst in several preparations and will indicate as such under these circumstances.

Since allowable variation in quantification of samples close to 1% is high, <1% may be reported. Such results are ideal for point counting, and the technique is mandatory for friable samples (NESHAP, Nov. 1990 and clarification letter 8 May 1991) under 1% percent asbestos or "trace asbestos".

In order to make all initial PLM reports issued from CA Labs NESHAP compliant, all <1% asbestos results (except floor tiles) will be point counted at no additional charge.

CA Labs is accredited by the National Voluntary Accreditation Program (NVLAP) for selected test methods for airborne fiber analysis (TEM), and for bulk asbestos fiber analysis (PLM). CA Labs is also accredited by AIHA LAP, LLC. in the PLM asbestos field of testing for Industrial Hygiene. All analysts have completed college courses or hold a degree in a natural science (geology, biology, or environmental science). Recognition by a state professional board in one these disciplines is preferred, but not required. Extensive in-house training programs are used to augment the educational background of the analyst. The Laboratory Director and Quality Manager have received supplemental McCrone Research training for asbestos identification.
