Dear Ms. Chen:

Attached is the hazardous building materials (hazmat) survey for the Junipero Serra Building located at 320 West 4th Street in Los Angeles, California (the “property” or “site”). The survey was completed pursuant to a request from the State of California, Department of General Services (DGS) for a hazmat survey related to the access barrier removal project. Avocet Environmental, Inc. subcontracted Advantage Environmental Consultants, LLC (AEC) to complete the survey.

AEC collected seven samples of buildings materials and had them analyzed for asbestos.

Samples of building materials included fire proofing, vinyl floor tile and mastic, ceiling tile, vinyl flooring, and leveling compound. The results of the analyses indicated that none of the samples contained asbestos.

A total of 15 x-ray fluorescence (XRF) readings were obtained during the survey for lead, none of which were found to contain lead at concentrations greater than the California Occupational Safety and Health Commission action level of 0.7 milligrams per square centimeter.

If you have any questions regarding the survey attached to this report, please do not hesitate to contact the undersigned at (949) 296-0977 Ext. 111 or at dsiren@avocetenv.com.

Junipero Serra Building 512 Hazardous Building Materials Survey Los Angeles, California AEC Project No. 18-119SD

1.0 Purpose and Methodology

The purpose of the Hazardous Building Material Survey was to locate and identify visible and accessible potentially hazardous materials that would require abatement prior to selective demolition to be completed at the property. The survey focused on asbestos containing materials (ACMs) and lead-based paint (LBP). The client directed sampling was completed to supplement the findings of a prior survey completed by others at the subject building in August 2013.

A State of California Certified Asbestos Consultant and United States Environmental Protection Agency (USEPA) certified building inspector for Asbestos- Containing Building Materials and a California Department of Health Services Certified Lead Inspector/Assessor performed the field inspection on March 27, 2018. Potential ACM and LBP identification was performed by evaluating each targeted work area as designated by a representative of the State of California Department of General Services. The physical conditions, friability, accessibility, activity and damage of suspect ACM was also assessed and documented. Readings for potential LBP were obtained from each building component identified within each room equivalent by the use of a hand held X-Ray Fluorescence (XRF) lead-based paint analyzer. Each reading location and condition of paint was documented.

The ACM survey methodology is summarized below:

Each suspect ACM was sampled in accordance with sampling guidelines established by the

USEPA. The following summarizes the sampling procedures utilized:

Building materials were categorized into homogeneous materials. A homogeneous material is defined as being uniform in texture, color, and date of application.

A sampling scheme was developed based upon the location and quantities of the various homogeneous materials.

Bulk samples were collected by extracting a representative section of the selected material, placing it in a sampling container and assigning a unique sample number. The samples were placed into a sealed shipping container for delivery to an accredited laboratory for analysis by polarized light microscopy (PLM).

The personnel performed proper decontamination procedures to prevent the spread of secondary contamination.

Each bulk sample was recorded on a bulk sample log and possession of the samples was tracked by a chain of custody record. The laboratory analyzed the building material samples and reported results in accordance with State of California protocol. The lower limit of reliable detection for this method is 1%. Samples that contain more than 1% of asbestos are reported in 5% ranges. Samples which contain asbestos in a concentration lower than the limit of reliable detection (<1%) are considered "Trace."

All bulk samples were analyzed by PLM in accordance with the "Interim Method for the Determination of Asbestos in Bulk Insulation Samples EPA - 600/M4-82-020" dated December 1982 and adopted by the National Voluntary Laboratory Accreditation Program (NVLAP) Title

15, part 7 of the Code of Federal Register as affiliated with the National Institute for Standards and Testing (NIST).

Seven (7) samples were obtained and analyzed for asbestos content by Eurofins CEI of Cary, North Carolina. Eurofins CEI is accredited by the American Industrial Hygiene Association, NVLAP, NIST, and is a successful participant in the Proficiency Analytical Testing Program

(PAT).

The LBP survey methodology is summarized below:

As stated previously, LBP readings were collected utilizing an XRF analyzer. Readings were collected in accordance with Chapter 7 of the HUD Guidelines for Evaluation and Control of Lead-Based Paint Hazards in Housing and U.S. Environmental Protection Agency (EPA) 40 CFR part 745 and Title X of the 1992 Housing and Community Development Act. A total of 15 XRF readings were obtained during the survey.

The California Department of Health Services standard for the definition of LBP is 1.0 mg/cm2.

However, the California Occupational Safety and Health Commission (CALOSHA) standard for the definition of LBP is 0.7 mg/cm2 and requires that all workers be properly protected when working with building components containing any level of lead in accordance with Title 8 CCR Section 1532.1.

The information above is designed to aid the building owner, architect, construction manager, general contractor of potential abatement contractors in locating affected building materials within the scope of work and access constraints identified in this report. Other lead containing building components may exist at the property within concealed areas of the property or outside the scope of work. All conditions of components identified in the above table were identified during the time of the survey.

3.0 Conclusions and Limitations

Neither ACM nor LBP were identified in the building materials sampled during this survey.

AEC warrants that our services are performed within the limits prescribed by our client with the usual thoroughness and competence of the engineering profession. Any recommendations in this report are professional opinions based solely on visual observations and analytical analyses, as described in this report. The scope for this assessment included visual observations and sampling of suspect ACM and LBP in designated accessible areas of the building. Non-repairable finishes are typically not penetrated and materials behind or underneath these finishes are considered inaccessible. In addition, subgrade sealants and suspect ACMs located behind brick, plaster, concrete masonry units (CMU), concrete, or behind and/or above solid walls and ceilings are not assessed to minimize damage (i.e. non-destructive) as a result of the bulk sample collection process.

Destructive investigative techniques were not conducted. Because the scope of services was limited to accessible and visible materials and intrusive investigative techniques were not contracted for or allowed, it is possible that unrecognized hazardous materials might exist. Any unassessed materials present in inaccessible locations that are discovered at a later time must be sampled prior to disturbance. Opinions and recommendations presented herein apply to site conditions existing at the time of our investigation and cannot necessarily apply to site changes of which AEC is not aware and/or has not had the opportunity to evaluate.

Due to the limitations of the EPA 600 method, nonfriable organically bound materials (NOBs) such as vinyl floor tiles can be difficult to analyze via polarized light microscopy (PLM). EPA recommends that all NOBs analyzed by PLM, and found not to contain asbestos, be further analyzed by Transmission Electron Microscopy (TEM). Please note that PLM analysis of dust and soil samples for asbestos is not covered under NVLAP accreditation. Estimated measurement of uncertainty is available on request.
