Limited Asbestos Survey Travis Air Force Base Building 549 - Stairs & Entry Way Travis, California Page 1 of 6

SECTION I EXECUTIVE SUMMARY

On November 9, 2022, American Compliance Services, LTD (ACS) conducted a limited asbestos survey of the stairs & entry way in Building 380B, at Travis Air Force Base, in Travis, California.

David Kummer and Sofia Kummer, Asbestos Certified Site Surveillance Technicians (CSSTs) conducted the survey.

SECTION II SCOPE OF WORK

The purpose of this survey was to test the drywall, flooring and ceiling for asbestos prior to disturbance of the material. Should the final construction plans change and require penetration into materials not included in this report, additional sampling and analysis will be required at this site.

SECTION III DEFINITIONS

ASBESTOS

A material is considered by the EPA and the State of California to be an Asbestos Containing Material (ACM) if at least one sample collected from the homogeneous area shows asbestos present in an amount greater than one percent (>1%) https://www.dir.ca.gov/title8/ch3_2sb2a2_5.html. California Code of Regulations (CCR) 1529 defines Asbestos Containing Construction Material (ACCM) as materials containing greater than one-tenth of one-percent (0.1) asbestos by weight. Under 1529 CCR, materials containing between 0.1 % and 1 % asbestos are still regulated as “other” operations by this standard. The ACCM designation is applicable only to reporting (user registration, temporary worksite notification, and incident reporting). https://www.dir.ca.gov/title8/1529.html

The removal or disturbance of 100 square feet or more of ACM or ACCM must be performed by a contractor certified by the California Contractor's State License Board to conduct asbestos-related work and/or an employer/contractor registered with the California Division of Occupational Safety and Health (DOSH) to perform asbestos-related work.

OSHA CLASSIFICATIONS

"Class I asbestos work" means activities involving the removal of TSI and surfacing ACM and

PACM.

"Class II asbestos work" means activities involving the removal of ACM which is not thermal system insulation or surfacing material. This includes, but is not limited to, the removal of asbestos-containing wallboard, floor tile and sheeting, roofing and siding shingles, and construction mastics.

"Class III asbestos work" means repair and maintenance operations, where "ACM", including TSI and surfacing ACM and PACM, is likely to be disturbed.

“Class IV asbestos work” means maintenance and custodial activities during which employees contact but do not disturb ACM or PACM and activities to clean up dust, waste and debris resulting from Class I, II, and III activities.

“Disturbance” means activities that disrupt the matrix of ACM or PACM, crumble or pulverize ACM or PACM, or generate visible debris from ACM or PACM. Disturbance includes cutting

Travis, California Page 2 of 6 away small amounts of ACM and PACM, no greater than the amount which can be contained in one standard sized glove bag or waste bag in order to access a building component. In no event shall the amount of ACM or PACM so disturbed exceed that which can be contained in one glove bag or waste bag which shall not exceed 60 inches in length and width.

NESHAP CATEGORIES

Friable Materials (RACM) NESHAP defines a friable ACM as any material containing more than one percent asbestos that when dry, can be crumbled, pulverized, or reduced to powder by hand pressure.

Category I Non-friable NESHAP defines a Category I non-friable ACM as packing, gaskets, resilient floor covering (except sheet flooring products which are considered friable), and asphalt roofing products which contain more than one percent asbestos.

Category II Non-friable NESHAP defines a Category II non-friable ACM as any material, except for a Category I non-friable ACM, which contains more than one- percent asbestos and cannot be reduced to a powder by hand pressure when dry.

SECTION IV ASBESTOS INSPECTION RESULTS & FINDINGS

ACS collected nine (9) asbestos samples from the building for laboratory analysis. EPA guidelines were used to determine the sampling protocol. Asbestos was detected in the flooring under the carpet. The results are summarized in the table below:

The Contractor must obtain all building and special permits required for the asbestos abatement work. When removing 100 square or linear feet or greater of asbestos containing material with an asbestos content of greater than one-tenth of one-percent (0.1) asbestos by weight., the work must be performed by an entity that holds a current, valid asbestos handling license issued by the California State Contractor’s Licensing Board (SCLB) and a current valid Certificate of Registration for Asbestos-Related Work issued by the California Department of Industrial Relations-Division of Occupational Safety and Health (DOSH), unless otherwise specified.

SECTION V METHODS

Asbestos Inspection and sampling procedures were performed in general accordance with the guidelines published by the Environmental Protection Agency (EPA) in 40 CFR Part 763 Subpart E, October 30, 1987. The survey consisted of three major activities: visual inspection and physical assessment, sampling, and quantification of building materials.

ASBESTOS BULK SAMPLE ANALYSIS

Micro Analytical Laboratory in Emeryville, California performed the Asbestos analysis. A chain-of-custody form submitted with the bulk samples, documented the possession of the samples from the time they were collected until they were analyzed. The original chain-of-custody accompanied the samples at all times. Custody documentation began at the time the sample was collected and a copy of the chain-of-custody record was retained by each transferor. The laboratory performed the asbestos analysis using the bulk sample for visual observation and slide preparation(s) for microscopic examination and identification. They mounted samples on slides and then analyzed the samples for asbestos (chrysotile, amosite, crocidolite, anthophyllite, and actinolite/tremolite), fibrous non-asbestos constituents (mineral wool, paper, etc.) and non-fibrous constituents. Asbestos was identified by refractive indices, morphology, color, pleochroism, birefringence, extinction characteristics, and signs of elongation. The same characteristics were used to identify the non-asbestos constituents. The microscopist visually estimated relative amounts of each constituent using a stereoscope to determine the volume of each constituent in proportion to the total volume of the sample.

All bulk samples were analyzed by Polarized Light Microscopy (PLM) with dispersion staining as described by the method of the determination of asbestos in bulk insulation, EPA/600/R-93/116, July 1993. This is a standard method of analysis in optical mineralogy and the currently accepted method for the determination of asbestos in bulk samples. A suspect material is immersed in a solution of known refractive index and subjected to illumination by polarized light. The characteristic color displayed enables mineral identification. It should be noted that some ACM might not be accurately identified and/or quantified by PLM. As an example, the original fabrication of vinyl floor tiles routinely involved milling of asbestos fibers to extremely small sizes.

As a result, these fibers may go undetected under the standard polarized light microscopy method. Transmission Electron Microscopy (TEM) is required for a more definitive analysis of these materials.

QUANTIFICATION

The material location maps display the location of the asbestos containing material. Please see the available plans for the quantity of material included in the scope of work.
