1.0 Executive Summary

Advantage Environmental & Safety Services (AESS) was retained to perform an asbestos- and lead-containing materials survey of designated interior areas at the United States Coast Guard (USCG) Air Station Sacramento, located at 6037 Price Avenue, McClellan Park, California 95652 (the “Site”). The survey was performed on July

13, 2026 by Matt Bailey, Certified Site Surveillance Technician (CSST) and Lead Sampling Technician, of AESS, and consisted of representative bulk sampling of suspect asbestos-containing materials (ACM) and suspect lead-containing building materials within first- and second-floor areas identified on the sample location diagrams provided as Figures 1 and 2 (Section 5.3).

Forty-three (43) bulk samples (representing 91 individual material layers) were collected and submitted for

Polarized Light Microscopy (PLM) analysis of asbestos content – forty-two (42) samples (90 layers) under

Schneider Laboratories Order No. 696941, and one (1) point-count sample (1 layer, concrete) under Order No.

696944. Asbestos was detected in the black, bituminous mastic layer beneath two 12-inch by 12-inch resilient floor tile samples – Sample 071326-CGMC-29 (1st Floor, Men’s Locker Room [MLR], A wall) and Sample 071326-

CGMC-33 (1st Floor, MLR hallway) – each containing 4% chrysotile asbestos. No asbestos was detected in the remaining 89 sample layers. Fourteen (14) bulk samples were collected and submitted for total lead analysis by flame atomic absorption spectroscopy (EPA Method 7000B). Detectable lead was identified in nine (9) of the fourteen samples. Three of those samples – Pb5 (red paint on the concrete kitchen floor, 5,090 mg/kg / 0.509%), Pb10 (white paint on an 8-inch structural steel I-beam, 110,000 mg/kg / 11.0%), and Pb11 (blue paint on the same I-beam, 124,000 mg/kg / 12.4%) – exceeded the federal regulatory definition of lead-based paint (≥ 0.50% by weight / ≥ 5,000 mg/kg). A fourth sample, Pb12 (blue paint on CMU, 1st Floor MLR hallway), was detected at

0.496% (4,960 mg/kg), just below the regulatory threshold. No lead was detected above the laboratory reporting limit in the remaining five samples (Pb1, Pb7, Pb8, Pb9, and Pb14).

A summary of findings and AESS recommendations is provided in Sections 5.0 and 6.0 of this report. Complete laboratory analytical reports, chain-of-custody documentation, and the sample location diagrams (Figures 1 and

2) are included as Appendices A and B, with applicable personnel certifications provided in Appendix C.

2.0 Introduction and Scope of Work

This report presents the results of a limited asbestos- and lead-containing materials survey conducted by AESS at the request of the United States Coast Guard in connection with planned maintenance, renovation, or abatement-related activities at Air Station Sacramento. The purpose of the survey was to identify the presence and approximate concentration of asbestos and lead in designated suspect building materials so that appropriate handling, abatement, and disposal procedures can be planned prior to disturbance of those materials.

The scope of work performed by AESS included the following:

• A visual survey of designated interior spaces to identify homogeneous areas of suspect asbestos-containing and lead-containing materials.

Advantage Environmental & Safety Services | Confidential – Prepared for U.S. Coast Guard | Page 3 of 31

• Collection of forty-three (43) representative bulk samples of suspect ACM in general accordance with 40 CFR

Part 763 (AHERA) and EPA Method 600/R-93/116 sampling protocols.

• Collection of fourteen (14) representative bulk samples of suspect lead-containing materials (paint and ceramic tile/glaze).

• Submission of all samples under chain-of-custody to Schneider Laboratories Global, Inc. (Richmond, Virginia), an AIHA-LAP, LLC and NVLAP accredited laboratory, for analysis.

• Preparation of sample location diagrams and this summary report of findings.

This survey was limited to the specific materials, locations, and areas identified by AESS field staff and shown on the sample location diagrams in Figures 1 and 2 (Section 5.3). AESS did not perform a comprehensive, building-wide hazardous materials survey. Refer to Section 7.0, Limitations, for additional information regarding the scope and applicability of this report.

3.0 Site Description

The Site is the USCG Air Station Sacramento facility located at 6037 Price Avenue, McClellan Park, Sacramento

County, California. The areas surveyed include, on the first floor, the kitchen, men’s restroom/shower (MRR) facilities, men’s locker room (MLR) and adjoining hallway, women’s restroom (WRR), and adjacent shop and office areas; and, on the second floor, the crew lounge, duty rooms, snack store, and men’s restroom (MRR) facilities, together with adjoining corridor space, as depicted in the sample location diagrams (Figures 1 and 2, Section 5.3). Suspect materials sampled included ceramic wall and floor tile with associated setting materials

(mortar, thin-set, and grout), painted drywall, painted concrete masonry unit (CMU) walls, painted structural steel (I-beam), 12-inch by 12-inch resilient floor tile and associated black mastic, 2-foot by 4-foot acoustical ceiling tile, epoxy floor coatings and underlying concrete, rubber baseboard and glue, fiberglass-reinforced panel

(FRP) glue, wall panel adhesive, carpet glue, and drywall joint compound/texture systems.

4.0 Survey Methodology

4.1 Asbestos Sampling and Analysis

Suspect ACM was identified by visual inspection and grouped into homogeneous areas based on material type, color, texture, and apparent date of installation. Representative bulk samples were collected from each homogeneous area using wetting techniques and dedicated sampling tools to minimize fiber release, double-bagged, labeled, and submitted under chain-of-custody to Schneider Laboratories Global, Inc. Samples were analyzed by Polarized Light Microscopy (PLM) in accordance with EPA Method 600/R-93/116 and 40 CFR Part

763, Appendix E, Subpart E; one sample (concrete) was additionally analyzed by 400-point count in accordance with EPA Method 600/R-93/116 and California Air Resources Board (CARB) Method 435. Materials composed of multiple layers (e.g., tile / setting bed / grout, or drywall / joint compound / texture) were analyzed and reported by individual layer.

Advantage Environmental & Safety Services | Confidential – Prepared for U.S. Coast Guard | Page 4 of 31

4.2 Lead Sampling and Analysis

Suspect lead-containing painted surfaces and ceramic tile/glaze were sampled by removing a representative bulk chip or section of material. Samples were submitted under chain-of-custody to Schneider Laboratories Global, Inc. and analyzed for total lead content by flame atomic absorption spectroscopy in accordance with EPA

Method 7000B. Results are reported in milligrams of lead per kilogram of sample (mg/kg, equivalent to parts per million) and as percent lead by dry weight.

5.0 Summary of Findings

5.1 Asbestos Analytical Results

Forty-three bulk samples, representing 91 analyzed material layers, were submitted for PLM analysis under

Schneider Laboratories Order Nos. 696941 (42 samples / 90 layers) and 696944 (1 point-count sample / 1 layer, Sample 071326-CGMC-C1, concrete). Asbestos (4% chrysotile) was detected in the black, bituminous mastic layer of two 12-inch by 12-inch floor tile samples: Sample 071326-CGMC-29 (1st Floor MLR, A wall) and Sample

071326-CGMC-33 (1st Floor MLR hallway). No asbestos fibers were detected in any of the remaining 89 analyzed layers. The laboratory noted that three samples (071326-CGMC-19, -20, and -36), submitted as suspect 2-foot by

4-foot acoustical ceiling tile, were received as drywall rather than acoustical tile; these samples were analyzed and reported as received, and no asbestos was detected in these layers. A summary of sampled materials is provided in Table 1; the complete laboratory report is included as Appendix A.

5.2 Lead Analytical Results

Fourteen bulk samples (Schneider Laboratories Order No. 696944) were submitted for total lead analysis.

Detectable lead was identified in nine of the fourteen samples. Three samples – Pb5 (red paint on the concrete kitchen floor, 5,090 mg/kg / 0.509%), Pb10 (white paint on an 8-inch structural steel I-beam, 110,000 mg/kg /

11.0%), and Pb11 (blue paint on the same I-beam, 124,000 mg/kg / 12.4%) – exceeded the current federal regulatory threshold defining lead-based paint (0.50% by weight / 5,000 mg/kg). A fourth sample, Pb12 (blue paint on CMU, 1st Floor MLR hallway), was detected at 0.496% (4,960 mg/kg), just below that threshold. Lower concentrations of lead were also detected in Samples Pb2, Pb3, Pb4, Pb6, and Pb13. No lead was detected above the laboratory reporting limit in Samples Pb1, Pb7, Pb8, Pb9, and Pb14. Results are summarized in Table 2; the complete laboratory report is included as Appendix B.

6.0 Conclusions and Recommendations

6.1 Asbestos

Asbestos-containing material (ACM) was identified in the black, bituminous mastic underlying 12-inch by 12-inch resilient floor tile at two locations on the 1st floor: the A wall of the Men’s Locker Room (MLR) (Sample 071326-

CGMC-29) and the adjoining MLR hallway (Sample 071326-CGMC-33). Both mastic layers contained 4% chrysotile asbestos. No other asbestos-containing materials were identified among the 89 remaining sample layers collected within the areas surveyed.

Under 40 CFR Part 61, Subpart M (NESHAP), floor tile and associated mastic of this type is typically classified as

Category I nonfriable ACM in its current, undisturbed condition. Category I nonfriable ACM that is removed intact, without sanding, grinding, cutting, or abrading, and that is not in poor condition, is generally not subject to NESHAP notification and specialized work-practice requirements; however, if the material will be rendered friable during removal (e.g., by mechanical abrasion) or if the quantity disturbed meets the regulatory threshold, Shawn Jenkins Highlight

Shawn Jenkins Highlight

Advantage Environmental & Safety Services | Confidential – Prepared for U.S. Coast Guard | Page 9 of 31

NESHAP notification and handling requirements apply. Independent of NESHAP classification, disturbance of the identified ACM is subject to the Cal/OSHA Asbestos Construction Standard (8 CCR Section 1529), which requires use of a registered asbestos abatement contractor, a Certified Asbestos Consultant-developed removal specification, competent-person oversight, and appropriate engineering controls and personal protective equipment for Class I and Class II asbestos work.

• AESS recommends that the identified floor tile and mastic (Sample locations 071326-CGMC-29 and -33, 1st

Floor MLR) be removed by a licensed and registered asbestos abatement contractor in accordance with

Cal/OSHA and, if applicable, NESHAP requirements prior to any renovation, flooring replacement, or demolition activity affecting these areas.

• Waste generated from removal of the identified ACM should be manifested and disposed of as asbestos-containing waste material in accordance with applicable federal, state, and local regulations.

• The remaining 89 sampled material layers did not contain asbestos above the laboratory reporting limit and are not subject to asbestos-specific handling requirements based on these results; however, three samples

(071326-CGMC-19, -20, and -36) were noted by the laboratory as not matching the material described on the chain-of-custody (submitted as acoustical ceiling tile, received as drywall). The actual acoustical ceiling tile at these locations, if present, has not been characterized and should be sampled prior to disturbance.

• As with all limited surveys, any suspect material encountered outside the scope of this survey, or any location not represented by a collected sample, should be presumed to contain asbestos or should be sampled and analyzed prior to disturbance.

6.2 Lead

Detectable lead was confirmed in nine of the fourteen samples collected. Three samples exceeded the federal regulatory definition of lead-based paint (≥ 0.50% by weight / ≥ 5,000 mg/kg): Sample Pb5 (red paint on the concrete kitchen floor, 1st Floor Kitchen), at 0.509% (5,090 mg/kg); Sample Pb10 (white paint on an 8-inch structural steel I-beam, 1st Floor MLR, C wall), at 11.0% (110,000 mg/kg); and Sample Pb11 (blue paint on the same I-beam), at 12.4% (124,000 mg/kg). A fourth sample, Pb12 (blue paint on CMU, 1st Floor MLR hallway), was detected at 0.496% (4,960 mg/kg) — just below the regulatory threshold, but confirming the presence of lead at a concentration AESS recommends be managed as lead-containing material. Lower concentrations of lead, below the federal LBP threshold but above the laboratory reporting limit, were also detected in Samples

Pb2, Pb3, Pb4, Pb6, and Pb13 (ceramic tile and painted CMU surfaces). No lead was detected above the laboratory reporting limit in Samples Pb1, Pb7, Pb8, Pb9, and Pb14. AESS recommends the following:

• Personnel performing demolition, cutting, grinding, sanding, or removal of the painted I-beam surfaces

(Samples Pb10/Pb11), the painted concrete kitchen floor (Sample Pb5), and the painted CMU wall in the

MLR hallway (Sample Pb12) should be made aware that these materials contain lead at or approaching levels requiring compliance with the OSHA Lead in Construction Standard (29 CFR 1926.62), including exposure assessment, engineering controls, and personal protective equipment as warranted by the specific task performed.

• Debris and waste generated from removal or disturbance of the identified lead-containing paint and coatings should be evaluated for appropriate hazardous waste characterization (e.g., TCLP or California

TTLC) prior to disposal, consistent with California hazardous waste regulations.

Advantage Environmental & Safety Services | Confidential – Prepared for U.S. Coast Guard | Page 10 of 31

• The remaining sampled ceramic tile and painted surfaces with lower detected lead concentrations (Samples

Pb2, Pb3, Pb4, Pb6, and Pb13) should also be handled in accordance with OSHA lead-in-construction requirements when disturbed, notwithstanding that they fall below the federal lead-based paint threshold.

• As with asbestos, any suspect painted, coated, or glazed material outside the scope of this survey should be presumed to contain lead or should be sampled prior to disturbance.
