INSPECTION TYPE INSPECTED AREAS INSPECTION DATE

Commercial Maintenance Building January 11, 2022

II. INSPECTION SUMMARY

Samples of building materials considered to be suspect asbestos containing materials* were identified and collected from the inspected renovation areas referenced above to determine their asbestos content. Samples collected from specific areas for the purpose of renovation activities are determined by the client. There maybe areas within the Subject Site that were not inspected and may contain additional suspect asbestos containing materials that were not sampled. Through proper chain-of-custody the collected samples are sent to BEM, Inc Laboratories for polarized light microscopy (PLM) analysis. A summary of all materials sampled and corresponding analytical results are listed below. Detailed information regarding sample number, actual sample location and analytical methods can be reviewed in attachments A and B.

III. DEFINITIONS (*)

Suspect Asbestos Containing Material (ACM) - Local air quality management districts consider a material that is not wood, metal or glass, to be a suspect ACM. All suspect ACMs are assumed to contain asbestos until laboratory analysis confirms that a material has no asbestos content.

Category – ACM’s are classified as either “friable”, material that can be easily crushed or pulverized by normal hand pressure or as “non-friable”, material that cannot be easily crushed or pulverized by normal hand pressure. Friable ACMs are considered a Regulated Asbestos Containing Material (RACM) requiring Class I work practices and engineering controls. Non-friable ACMs are considered either Category I or Category II Asbestos Containing Material requiring Class II work practices and engineering controls.

Trace - Analytical result that is equal to or less than 1.0 percent asbestos by weight, but greater than 0.1 percent. Materials with a trace amount of asbestos have to be removed as asbestos containing construction material (ACCM) according to Cal-OSHA, but can be disposed as non-ACM upon point count analyses according to federal and state EPA regulations.

Homogeneous – Multiple samples collected of a suspect material that is similar in general appearance and from areas that appear to have been constructed at the same time are considered homogeneous. If multiple samples are collected from a similar material within a homogeneous area and only one of the multiple samples is found to contain asbestos, regulations mandate that the entirety of that material with the homogeneous area must be considered an ACM.

VFT – Vinyl Floor Tile TBD – To be determined

IV. ASBESTOS REGULATORY STANDARDS

California Occupational Safety and Health Administration (Cal-OSHA)

▪Friable and Non-Friable ACCMs containing more than 0.1 percent asbestos by weight are regulated.

▪Enforces regulations pertaining to workers performing ACCM removal and workers in close proximity.

▪Contractors who disturb more than 100 square feet or 160 lineal feet of ACCM must be registered by the contractor’s state license board as an asbestos removal contractor.

▪Contractors who disturb any amount of ACCM must ensure employee protection by providing accredited training, medical examinations, personal protective equipment and a negative exposure assessment.

United States Environmental Protection Agency (EPA)

▪Friable and Non-Friable ACMs containing more than 1.0 percent asbestos by weight are regulated.

▪Enforces regulations pertaining to protecting the environment, not workers.

▪Abatement Contractors who disturb more than 160 square feet or 260 linear feet of ACM must comply with the National Emissions Standards for Hazardous Air Pollutants Asbestos Regulations (40 CFR 61, Subpart M) and all state and federal requirements regarding asbestos.

Local Air Quality Control Districts

▪Friable and Non-Friable ACM’s containing more than 1.0 percent asbestos by weight are regulated.

▪Enforces regulations pertaining to local air quality; “No Visible Air Emissions”.

▪Require an asbestos survey prior to renovation or demolition.

▪Abatement Contractors who disturb more than 160 square feet or 260 linear feet of ACM must comply with the National Emissions Standards for Hazardous Air Pollutants Asbestos Regulations (40 CFR 61, Subpart M).

V. RECOMMENDATIONS

BEM recommends compliance with all federal, state and local regulations concerning asbestos.

VI. WARRANTY

Samples of suspect asbestos containing building materials, which could be disturbed during construction activities, are collected by BEM. Site inspections and sample collection methodologies are performed to meet regulatory standards and industry protocols. BEM warrants that the findings contained herein have been promulgated in general accordance with accepted professional practices at the time of its preparation as applied by professionals in the community. There is a possibility that conditions may exist in which suspect ACM’s could not be identified within the scope of the survey or were not apparent or accessible during the site visit. All scheduled work should cease and additional samples should be collected if unidentified suspect ACM’s are discovered during construction activities.

If quantities of asbestos containing materials are stated in this report, they are supplied for budgetary and regulatory notification purposes only. They should not be relied on for abatement bidding purposes.

VII. DISCLAIMER

If asbestos containing materials were impacted and/or damaged during a fire loss, then the soft and/or porous building materials and personal contents should be removed and disposed of as Asbestos Containing Building Materials (ACBM). The hard and/or nonporous building materials and personal contents can be cleaned and decontaminated on site. The locations surrounding the damaged areas should be considered contaminated with asbestos. BEM cannot assume these other areas were not impacted with asbestos. BEM recommends to either assume the building materials and/or personal contents within these surrounding locations are contaminated with asbestos; or micro-vac TEM samples can be collected within these surrounding locations to determine if the asbestos contamination migrated to these surrounding locations adjacent to the known contamination.

Dear Customer:

Enclosed are asbestos analysis results for PLM Bulk samples received at our laboratory on January 12, 2022. The samples were analyzed for asbestos using polarizing light microscopy (PLM) under EPA 600 Method.

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% asbestos by weight as determined by visual estimation.

Kind Regards, Laboratory Director

Samples were received in acceptable condition unless otherwise noted. All samples are received from the client; therefore, BEM Laboratories is not responsible for any of the sampling procedures.

Due to the limitations of the EPA 600 method, nonfriable organically bound materials (NOB’s) such as vinyl floor tiles can be difficult to analyze via polarized light microscope (PLM). EPA recommends that all NOB’s analyzed by PLM, and found not to contain asbestos, be further analyzed by Transmission Electron Microscopy (TEM).

BEM is accredited with the Environmental Laboratory Accreditation Program (ELAP) under Certificate Number 3013.

BEM successfully participates in the American Industrial Hygiene Association’s (AIHA) Bulk Asbestos Proficiency Analytical Testing Program (BAPAT) under Laboratory Identification Number 221538 and the National Voluntary Laboratory Accreditation Program’s (NVLAP) Bulk Asbestos Proficiency Test under Lab Code 901038.

This report applies to the standards and/or procedures identified and to the sample (s) tested. The test results are not indicative or representative of the lot from which the sample was taken or apparently identical or similar products. These reports are for the exclusive use of the addressed client and are released on the condition that they will not be reproduced without special written permission; therefore, BEM laboratories can provide assurance that no parts of the report are taken out of context. Samples not destroyed during testing are retained for a maximum of thirty days. All analyses are derived from calibrated visual estimate unless otherwise noted.
