Subject: Limited Asbestos Assessment San Bernardino International Airport - Sherriff’s Aviation Flight Line Re-Pavement Project 199 Hangar Way, San Bernardino, CA 92415 EFI Job Number: 045.14911

1. Introduction

San Bernardino County, Project and Facilities Management Department (referred to hereunder as the client) retained EFI Global to perform limited sampling of suspect asbestos containing materials (ACM) within the Sherriff’s Aviation Flight Line Re-Pavement Project Area (See project area map in Appendix I).

Per the client, the assessment was limited to the asphalt and concrete materials only located in the project area only.

The limited assessment was performed on September 18, 2025, by Joshua Everett, a DOSH Certified Asbestos Consultant (DOSH Cert No. 19-6687).

2. Asbestos Assessment

The purpose of this assessment was to conduct bulk sampling in order to determine the presence or absence of Asbestos Containing Material (ACM) in at the subject property. The scope of this assessment included reviewing any provided building records and/or previous investigation records, visually identifying homogeneous sample areas, collecting bulk samples of suspect ACM / ACCM, recording the friability and condition of suspect ACM/ACCM, interpreting the laboratory results, and producing a written report of findings and recommendations.

The sampling was performed in accordance with requirements of the following regulations:

Asbestos Hazard Emergency Response Act (AHERA); 40 CFR 763 Subpart E

Asbestos School Hazard Abatement Reauthorization Act (ASHARA); Section 206 of the Toxic Substance Control Act

National Emissions Standards for Hazardous Air Pollutants (NESHAPS); 40 CFR 61 Subpart M.

This report is a record of activities, observations, analytical results, and recommendations performed to date.

2.1 Asbestos Results Summary

The laboratory results indicate that the materials sampled during this assessment were found to be None Detected for asbestos content.

San Bernardino Internation al Airport Limited Asbestos Assessment

EFI Global Project Number: 045.14911

No other materials were sampled as part of this assessment.

Please refer to the Homogenous Material Sampling Table and Appendices for Materials, their locations, and approximate quantities.

2.2 Methodology

All samples were collected using a clean knife, chisel or the appropriate tools. Each sample was extracted carefully so as not to disturb adjacent materials while still penetrating through all layers of the material sampled.

Each sample was sealed in the appropriately sized plastic zip lock bag and the bag then labeled with a unique identification number. The sample number, description and location were then recorded on a log and plotted on a floor plan of the structure or area. Sampling tools were cleaned after collecting each sample. Any excess dust or debris from the sample location was cleaned using a moistened cloth. Whenever possible, samples were collected from previously damaged portions of the material in order to minimize damage to the material.

A total of seventeen (17) samples were submitted to AIH Laboratory in Anaheim, CA which is accredited under the NIST/NVLAP program for asbestos in bulk material by polarized light microscopy and the State of California for asbestos analysis. AIH Laboratory is NIST/NVLAP and California ELAP certified.

The analyses of the samples in this report were performed using polarized light microscopy using the EPA method 600/R-93/116. The phase abundances provided are visually estimated and expressed as percent area.

Total percentage of sample constituents may total greater than 100 due to trace amounts. The limit of detection for this analytical method is less than one percent. In multilayer samples, unless otherwise specified, the asbestos concentration is reported for the layer where asbestos is found. These results lie within the statistical limits of variability calculated for standard reference samples routinely analyzed in the laboratory. On a per sample basis, the accuracy and precision of the results depend on the type of sample and its asbestos content.

2.3 Regulatory Limits

Government agencies have promulgated different regulatory threshold levels to classify materials containing asbestos. The levels of asbestos content and the terms used to classify them differ. Listed below are the current regulatory agencies that have defined materials containing asbestos, along with the respective action levels, regulatory terminology and applicability:

2.4 Homogeneous Sample Materials Table

Homogeneous materials are defined as surfacing materials, thermal system insulation materials or miscellaneous materials that are uniform in color and texture. Homogenous sample areas are the areas where homogenous materials are located. Multiple sample locations are selected within each homogenous sample area to be a true representation of each homogenous material. Typically, a minimum of three (3) samples must be collected from each homogeneous area when sampling materials that may have variable asbestos content because it was batch mixed or applied by different contractors. High asbestos content variability is especially true of surfacing materials (sprayed-on and troweled on materials like plaster, fireproofing, acoustic ceiling, plaster) and thermal system insulation (TSI) used to insulate pipes, boilers, tanks or ducts to prevent heat loss.

As many as 9 samples may be collected of surfacing materials when they cover large surface areas.

Materials that appear to be homogeneous may in fact be different materials, installed at different times and have different material content in terms of asbestos; only laboratory testing can determine whether they are really the same homogeneous area. The below table presents the homogenous materials identified during the assessment and the asbestos content of those identified materials. The homogenous materials found to contain asbestos are listed in bold type.

2.4 Asbestos Recommendations

No recommendations regarding the material sampled during this assessment are provided in this report.

Any suspect materials, that are not identified above and may be impacted during work activities, must be presumed to contain asbestos until laboratory analysis of an adequate number of samples proves otherwise.

3.0 Limitations

The inspection and testing report is based on the condition of the subject property existing and apparent on the precise time and exact date of the inspection. Not all conditions may be apparent on the inspection and testing date due to weather conditions, inoperable systems, inaccessibility of areas of the subject property, or for other reasons.
