Limited Asbestos Inspection Report

Safety & Environmental Investigations, (SEI) Inc. was retained by HGL Construction, Inc. to perform a Limited pre-renovation asbestos inspection of the ceilings and HVAC System of Building 335 located at the Little Rock Air Force Base, Jacksonville, Arkansas. On November 29th, 2018, 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 Environmental Quality, Regulation 21.

Background

Building 335 is a single-story, brick structure with a pitched, shingled roof on a concrete slab foundation. The interior of the structure consisted of lay-in ceiling tiles, sheet rock walls and ceilings with carpet, tile and concrete flooring. 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 ceiling and HVAC system.

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 identified areas of the structure. Identified asbestos-containing materials have been quantified.

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

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 BH&M Environmental Consultants, Inc. Millington, Tennessee.

BH&M is accredited by the National Voluntary Laboratory Accreditation Program for Bulk Asbestos Analysis (NVLAP Air and Bulk #201018-0). 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 materials sampled from the structure, along with the analytical results and locations of the materials.

Safety & Environmental Investigations, Inc. has received the analytical results from the samples collected from Building 335 located at the Little Rock Air Force Base in Jacksonville, Arkansas. The analysis revealed No Asbestos Detected in the samples collected. Planned renovations to the HVAC system may proceed without regard to asbestos-containing materials.

Discussion

A 10-Day Notice of Intent (NOI) is also required to be filed with the Arkansas Department of Environmental Quality (ADEQ) for any demolition or the removal of RACM exceeding 160 square or 260 linear feet.

Sample locations and the location of identified asbestos materials are identified on drawings included in the appendices of this report.

Other materials identified on-site but deemed not-suspect includes the following:

fiberglass batt insulation, fiberglass duct insulation and rubber pipe insulation.

Limitations

This report relates to the ceiling and HVAC materials of Building 335 located at the Little Rock Air Force Base in Jacksonville, Arkansas. No other materials were noted or sampled during this investigation. According to the client, the structure is scheduled for future renovations to the HVAC system.

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 BH&M Environmental Consultants, Inc.

Millington. Tennessee. BH&M is solely responsible for all asbestos analytical results contained in and referred to in this report.
