Asbestos Report 1800 Cabrillo Memorial Drive San Diego, CA

1. Overview

Mike Anderson, an EPA AHERA-accredited building inspector representing San Diego Testing, performed limited asbestos testing at 1800 Cabrillo Memorial Drive, San Diego, CA 92106 on 07/05/2023. The property owner is Cabrillo National Monument, which can be reached at (619) 523-4285. The site is a national park facility. Testing included exterior suspect roof surfaces expected to be impacted by an upcoming renovation.

Test methods used for asbestos testing by San Diego Testing included bulk sample collection and analysis at Eurofins EMLab P&K, an accredited laboratory in San Diego.

2. Regulatory Background

The Cal/OSHA Asbestos in Construction Standard, CCR Title 8 Section 1529 applies when asbestos containing material is removed or disturbed in any quantity during construction related activities (except when a home-owner is doing work inside his own home). Materials found to contain asbestos with concentrations above 0.1% must be handled by an asbestos abatement contractor.

The San Diego County Air Pollution Control District (APCD), Rule 1206, applies to institutional, commercial, public, or industrial facilities, as well as residential buildings, condominiums, or apartments that contain more than four dwelling units. Additionally, a group of residential buildings located on the same property, managed by a common entity, falls under the Rule, such as a single-family home with a granny flat. The Rule requires that a facility survey be conducted prior to renovation or demolition of 100 square feet or more in 365 days or one calendar year, and prior to submitting a "Notice of Intention Form" to the APCD. A complete copy of the facility survey must be maintained onsite for the duration of any renovation and/or demolition operation, and be made available to APCD upon request. There are no exclusions related to construction date(s) of the structure(s).

The EPA's National Emission Standards for Hazardous Air Pollutants (NESHAP) standard requires an owner or operator of a renovation or demolition activity occurring in an institutional, commercial, public, or industrial structure, installation, or building to thoroughly inspect the affected facility or part of the facility where the demolition or renovation operation will occur for the presence of asbestos. There are no exclusions related to construction date(s) of the structure(s).

4. Summary and Recommendations

No asbestos was detected in any of the samples collected. No recommendations are warranted.

5. Limitations

This assessment was limited to specific exterior areas/materials to be impacted by an upcoming project at the direction of the property representative. Additional asbestos materials may be present at the property and this report should not be used for the purposes of a different renovation or demolition project in place of a comprehensive asbestos/lead survey for regulatory compliance.

In the event untested suspect asbestos materials are discovered during the course of demolition they should be sampled or assumed to be above regulatory thresholds.

The test report shall not be reproduced except in full, without written approval of the laboratory. The report must not be used by the client to claim product certification, approval, or endorsement by any agency of the federal government. The Company reserves the right to dispose of all samples after a period of thirty (30) days, according to all state and federal guidelines, unless otherwise specified.

Inhomogeneous samples are separated into homogeneous subsamples and analyzed individually. ND means no fibers were detected. When detected, the minimum detection and reporting limit is less than 1% unless point counting is performed. Floor tile samples may contain large amounts of interference material and it is recommended that the sample be analyzed by gravimetric point count analysis to lower the detection limit and to aid in asbestos identification.

‡ A "Version" indicated by -"x" after the Lab ID# with a value greater than 1 indicates a sample with amended data. The revision number is reflected by the value of "x".
