Subject: Limited Lead 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 lead-based coatings (LBP) within the Sherriff’s Aviation Flight Line Re-Pavement Project Area (See project area map in Appendix I).

The limited assessment was performed on September 26, 2026, by Joshua Everett, a CDPH Lead Inspector Assessor (CDPH Cert No. LRC-00013124).

2. Lead-Based Paint Assessment

A total of fifty-two (52) XRF readings were collected to test painted and coated surfaces for lead-based paint (LBP). The results are summarized in Section 2.1 and the table of results attached in Appendix II.

2.1 Lead Results Summary

None of the painted components tested by XRF are at or above the respective levels considered to be lead-based paint (LBP); however, paint may contain detectable levels of lead in the coatings which make work impacting those surfaces subject to the OSHA Lead Exposure in Construction Standard (CFR 29 1926.62) and Cal / OSHA Lead in Construction Standard (Title 8 CCR 1532.1).

Sampling for this inspection was representative and any components that were not tested but similar to those components that tested positive for LBP shall be considered and treated as lead laden.

2.2 Methodology

XRF testing of the painted surfaces was patterned after the inspection protocol in Chapter 7 of the HUD Guide Lines for the Evaluation and Control of Lead-Based Paint Hazards in Housing. In every “room equivalent” within the tested property, one representative surface of each “testing combination” was tested. Multiple readings were collected to resolve inconsistencies in the test results.

The method employed was X-ray fluorescence (XRF) using a Heuresis PE 200i Cobalt 57. The instrument was operated in “Quick Mode,” where the duration for each test result is determined by a combination of:

San Bernardino International Airport Limited Lead Assessment

EFI Global Project Number: 045.14911 the actual reading relative to the designated action level;

the age of the radioactive source; and the substrate on which the test was taken.

The instrument’s calibration was verified according to the manufacturer's specifications in compliance with the Performance Characteristic Sheet (PCS) developed for this instrument.

The readings from this instrument produce a 95% confidence level that the “lead” reading accurately reflects the actual level of lead in the tested surfaces, relative to the federal action level.

2.3 Regulatory Limits

Government agencies have promulgated different regulatory threshold levels to classify Lead-Based Paint. Some of the established “levels” are quantified in different units of measurement. Listed below are the current regulatory agencies that have defined LBP, along with the respective action level:

Agency Ordinance # Action level (mg / cm2) Action level (ppm) HUD / EPA 24 CFR 35.86 & 40 CFR 745.103 1.0 mg / cm2 5,000 ppm L.A. County Title 11, 11.28.010 0.7 mg / cm2 Not Specified OSHA / CAL OSHA 29 CFR 1926.62 & Title 8, 1532.1 Not Specified 600 ppm

The Federal threshold for lead-based paint, 0.5 percent by weight, is higher than the local Los Angeles County action level and the lower of the two thresholds is the one that everyone within Los Angeles County must adhere

to. In recognition of the various action levels the testing results are classified as follows for this report:

Painted surfaces with readings at or above 1.0 mg / cm2 are considered - Positive

Painted surfaces with readings below 1.0 mg / cm2 are considered - Negative

The individual readings have been provided in the XRF Results Table located in Appendix IV. Any future change in action levels by one of the regulating agencies may affect the classification of results.

For purposes of this survey, any material containing any detectable level of lead is subject to OSHA’s Lead Exposure in Construction Rule (29 CFR Part 1926) and CAL/ OSHA Lead in Construction Standard (Title 8 CCR 1532.1). Any work that impacts these materials must be performed in accordance with these and any other applicable standards.

2.4 Lead Recommendations

Paint found not to contain lead concentrations considered to be LBP may still contain detectable levels of lead in the coatings which make work impacting those surfaces subject to Cal / OSHA Lead in Construction Standard

1532.1. This standard requires that respiratory protection and containment is used when performing “trigger tasks” until results of personal air monitoring indicate that workers are not exposed to lead above the action level or permissible exposure level. Additionally, the demolition or removal of lead or components with lead coatings is subject to Title 17, Division 1, Chapter 8 of the California Code of Regulations.

Should the contractor choose not to remove the lead-based paint materials and demolish the structure in its entirety with the lead-paint components in place, it is recommended that the contractor stabilize the LBP components prior to demolition and then collect samples representative of the entire mass of the prospective waste stream. These samples should then be analyzed according to the United States Environmental Protection

EFI Global Project Number: 045.14911

Agency (EPA) and the California Department of Toxic Substances Control (DTSC) prior to disposal facility acceptance.

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.

EFI Global has prepared this report for the exclusive use of its client. EFI Global, in performing its professional services, has applied scientific judgment that it believes is consistent with industry standards. EFI Global inspected structures and/or contents in a good faith effort to observe pertinent detail. Due to the limitations of time, access, and other variables, certain details may have been overlooked. EFI Global has relied in good faith upon the information and representations of others in the preparation of this report and the opinions expressed herein. Accordingly, EFI Global accepts no responsibility for deficiencies, omissions, misrepresentations, or fraudulent acts of persons interviewed.

EFI Global assumes no liability for any loss, injury, claim, or damage arising directly or indirectly from any use or reliance on this report or the opinions expressed herein. EFI Global makes no warranty, express or implied. This report is limited only to the samples taken and locations sampled. Additional sampling may be needed to further identify other pollutants or asbestos affected areas inside the property.

Since destructive investigation was not performed during the survey, the report may not reveal concealed asbestos-containing materials. Subsequently, additional investigation including construction documents review and/or destructive investigation is recommended as a precaution to prevent accidental exposure when construction or demolition is planned for this facility.

Thank you for the opportunity to work with you on this project. Please contact the undersigned at (310) 854- 6300, if you have questions or if additional services are necessary.
