PRE-RENOVATION HAZARDOUS MATERIALS SURVEY

California Veteran Affairs (Cal-Vet) Building 1227 O Street

Sacramento, California

Terracon Project No. NB247034 May 20, 2024

1.0 INTRODUCTION

Terracon Consultants, Inc. (Terracon) conducted a pre-renovation hazardous materials survey of the existing and tentatively planned expanded electrical vault on the ground floor and electrical rooms on the 1st – 6th floors, and roof level at the California Veteran Affairs (Cal-Vet) Building located at 1227 O Street in Sacramento, California (Site). The survey was conducted April 25, 2024, in general accordance with Terracon’s proposal PNB247034, dated March 1, 2024, and the asbestos sampling protocols established in Environmental Protection Agency (EPA) regulation 40 Code of Regulations (CFR) Part 763 Subpart E 763.86, (Asbestos Hazard Emergency Response Act, AHERA). The survey scope included limited invasive sampling methods within the referenced survey area and north and east elevations of the exterior at the ground floor. The remaining interior, exterior and roof of the building were excluded from the scope of the survey. The survey included sample collection of suspect asbestos-containing materials (ACMs), lead containing paints (LCPs) and materials, and polychlorinated biphenyls (PCBs) materials. Other hazardous building materials were noted, if observed.

1.1 Project Objective

The objective of this survey was to identify the presence or absence of suspect ACMs and lead containing paints and materials, PCBs in materials (light ballasts, and building enclosure sealants), universal waste (fluorescent light tubes, mercury containing switches, batteries), tritium (radioactive) emergency egress equipment, and regulated refrigerants in mechanical or building equipment associated within the survey areas of the site structure.

EPA regulation 40 CFR 61, Subpart M, the National Emission Standards for Hazardous Air Pollutants (NESHAP) prohibits the release of asbestos fibers to the atmosphere during renovation or demolition activities. The asbestos NESHAP requires that regulated ACM be identified, classified, and quantified prior to planned disturbances, renovations, or demolition activities.

3.0 FIELD ACTIVITIES

3.1 Asbestos, Lead, PCBs, and Other Hazardous Building Materials

The survey was conducted by Remington Caldwell, California Division of Occupational Safety and Health (Cal/OSHA) Certified Asbestos Consultant (CAC) and California Department of Public Health (CDPH) Lead Inspector/Assessor. Ken Pilgrim, CAC, managed the field survey and preparation of report. Copies of pertinent training certifications are included in Appendix F. The asbestos portion of the survey was conducted in general accordance with the sample collection protocols established in EPA 40 CFR Part 763 Subpart E 763.86, AHERA. A summary of survey activities is provided below.

3.2 Visual Assessment - Asbestos

Survey activities were initiated with visual observation of the survey area to identify homogeneous areas of suspect ACM. A homogeneous area (HA) consists of a building material

Facilities | Environmental | Geotechnical | Materials 3 that appears similar throughout in terms of color, size and texture with consideration given to the date of application. The assessment was limited to the referenced survey area.

3.3 Physical Assessment - Asbestos

A physical assessment of each HA of suspect ACM was conducted to assess the current friability and condition of the materials. A friable material is defined by the EPA as a material which can be crumbled, pulverized, or reduced to powder by hand pressure when dry. Friability was assessed by physically touching suspect materials.

Based on results of the visual observation, bulk samples of suspect ACM were collected in general accordance with EPA AHERA sampling protocols. Samples of suspect materials were collected from representative locations in each homogeneous area. Bulk samples were collected using wet methods as applicable to reduce the potential for fiber release. Samples were placed in sealable containers and labeled with unique sample numbers using an indelible marker.

The selection of sample locations and frequency of sampling were based on Terracon’s observations and the assumption that like materials in the same area are homogeneous in content.

Terracon collected one hundred twenty-six (126) samples from thirty-eight (38) homogeneous areas of suspect ACMs. Laboratory analysis reported that two (2) of the materials sampled contain asbestos. A summary of the materials reported as containing asbestos is included in Table I below and a summary of all suspect ACM samples collected during the survey is included as Appendix A.

3.4 Sample Analysis - Asbestos

Asbestos bulk samples were submitted under chain of custody to Eurofins EPK Built Environment Testing, LLC (Eurofins) in Tustin, California for analysis by polarized light microscopy (PLM) with dispersion staining techniques per EPA methodology 600/R-93/116. The percentage of asbestos, where applicable, was determined by microscopic visual estimation. Eurofins is accredited under the National Voluntary Laboratory Accreditation Program (NVLAP) Accreditation (No. 200757-0).

The laboratory reports for the asbestos bulk samples are included as Appendix B.

3.5 Lead Containing Paint and Materials

Terracon collected paint chip, building sealant, ceramic tile, and resilient flooring samples to determine the lead content in parts per million (ppm) of the predominant painted interior and exterior surfaces and materials associated with the survey area. Suspect lead samples were collected in sealable containers and labeled with unique sample numbers using an indelible marker.

3.6 Visual Assessment – Lead Containing Paint and Materials

Inspection activities began with visual observations of painted surfaces to identify unique combinations of paint. A unique combination of paint consists of paint that is applied to a building material and has similar color, substrate, and component. The assessment was conducted throughout the referenced survey areas. Suspect lead containing sealants, ceramic tile, and resilient flooring were observed within the survey area.

Facilities | Environmental | Geotechnical | Materials 4

3.7 Physical Assessment – Lead Containing Paint and Materials

A physical assessment of unique combinations of paint was conducted to assess the condition of the paint. Lead paint chip samples were collected to comply with Cal-OSHA regulations (Title 8 CCR 1532.1 – Lead Exposure in Construction) for the proposed demolition activities. Paint was sampled to identify potential worker exposure and potential disposal restrictions. All interior and exterior painted surfaces were in fair to good condition and generally intact with the building substrates at the time of the survey.

Terracon sampled twenty (20) painted surfaces and building materials during the survey. Thirteen

(13) of the paints and three (3) materials sampled were found to contain lead concentrations in exceedance of the laboratory detection limit. A summary of suspect lead paint and materials collected during the survey is summarized in Table II.

3.8 Sample Analysis - Lead Containing Paint

Paint chip and bulk samples were submitted under chain of custody to Eurofins in Tustin and were analyzed by Flame Atomic Absorption method SW846-7000B. Eurofins is accredited by the American Industry Hygiene Association’s (AIHA) Environmental Lead Laboratory Accreditation Program (ELLAP) (Laboratory Code 178697) to perform Flame Atomic Absorption analysis. The laboratory reports for the lead samples are included as Appendix C.

3.9 PCBs – Sealants

Terracon collected four (4) bulk samples from multiple building enclosure sealants at the north and east elevations of the ground floor during the survey. Sealants associated with building enclosure including windows were assessed for potential PCB content. Bulk sealant samples were collected using a razor knife and were placed into individual containers. Each sample was provided a discrete sample number, which was recorded on a chain of custody form. The samples were preserved on ice and transported under chain of custody procedures to McCampbell Analytical, Inc. in Pittsburg, California. All samples were analyzed for PCB content in accordance with EPA Method SW8082. The laboratory reports for the PCB samples are included as Appendix D. A summary of the PCB materials samples is included in Table III.

3.10 Visual Assessment - Other Hazardous Building Materials

The survey area of the building was visually inspected for the presence of mercury containing products such as fluorescent light tubes, compact fluorescent bulbs, switches, high intensity discharge (HID) bulbs, and thermometers. Lighting fixtures were screened for the potential presence of PCB containing ballasts. Equipment with refrigerants were inspected to identify refrigerant type(s) if labels were present and legible. Emergency egress equipment was identified and assessed for the presence of batteries, light emitting diodes (LEDs) or radioactive material such as tritium gas. All materials were visually assessed and quantified if present. No testing was performed.

4.0 REGULATORY OVERVIEW

4.1 Asbestos

The Asbestos NESHAP program in California is enforced by federal, state, and county Asbestos NESHAP Coordinators. For projects occurring in Sacramento, California, the Sacramento Metropolitan Air Quality Management District (SMAQMD) has been delegated authority from the EPA to enforce the Asbestos NESHAP within its respective jurisdictional boundaries, excluding tribal lands.

The asbestos NESHAP (40 CFR Part 61, Subpart M) regulates asbestos fiber emissions and asbestos waste disposal practices. The asbestos NESHAP regulation also requires the identification and classification of existing ACM according to friability prior to demolition or renovation activity.

Friable ACM is a material containing more than 1% asbestos that, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure. All friable ACM is considered regulated asbestos-containing material (RACM). The NESHAP regulation is implemented locally by the SMAQMD under Regulation 902.

The asbestos NESHAP regulation classifies ACM as either RACM, Category I non-friable ACM or Category II non-friable ACM. RACM includes all friable ACM, along with Category I and Category II non-friable ACM that has become friable, will be or has been subjected to sanding, grinding, cutting, or abrading, or ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder during renovation or demolition activity. Category I non-friable ACM are exclusively asbestos-containing packings, gaskets, resilient floor coverings, and asphalt roofing products that contain more than 1% asbestos. Category II non-friable ACM are all other non-friable materials other than Category I non-friable ACM that contain more than 1% asbestos.

Friable ACM, along with Category I and Category II non-friable ACM, which is in poor condition and has become friable or which will be subjected to drilling, sanding, grinding, cutting, abrading and which could be crushed or pulverized during anticipated renovation or demolition activities are considered regulated ACM (RACM).

Building materials confirmed to be ACM through the collection of bulk sampling and subsequent laboratory analysis, or presumed ACM, must be removed prior to intentional disturbance during the planned demolition activities. Asbestos abatement must be conducted by California licensed and registered abatement contractors and workers with Cal/OSHA-accredited training. Third-party air monitoring is recommended during the abatement activities.

Cal/OSHA requires that only properly licensed and certified asbestos abatement contractors be allowed to remove ACM. As per NESHAP, all RACM shall be removed from a facility being demolished or renovated before any non-burning demolition or renovation begins that would break up, dislodge, or similarly disturb the material or preclude access to the material for subsequent removal. According to the SMAQMD Regulation 902, if more than 160 square feet or 260 linear feet of any RACM is to be stripped, removed, dislodged, cut, drilled, or similarly disturbed, or for any demolition, the asbestos abatement contractor or facility owner must submit an Asbestos Notification of Demolition and Renovation form to the SMAQMD along with the appropriate fees within at least 10 working days prior to the scheduled asbestos removal activity or demolition start date. Planned renovations that do not meet the definition of ‘demolition or renovation of a facility’ per SMAQMD and where no ACM exists do not require notification to

NESHAP.

The Cal-OSHA asbestos standard for construction (Title 8 CCR 1529) regulates workplace exposure to asbestos. The Cal-OSHA standard requires that employee exposure to airborne asbestos must not exceed 0.1 fibers per cubic centimeter of air (0.1 f/cc) as an eight-hour time weighted average (TWA) and not exceed 1.0 fibers per cubic centimeter of air (1.0 f/cc) over a 30-minute time period known as an excursion limit (EL). The TWA and EL are known as Cal- OSHA’s asbestos permissible exposure limits (PELs). The Cal-OSHA standard classifies construction and maintenance activities which could disturb ACM and specifies work practices and precautions which employers must follow when engaging in each class of regulated work.

Asbestos containing construction materials (ACCM) is a term developed by Cal/OSHA out of concern for non-hazardous building materials used inside and outside a building that contain less than 1% asbestos. The definition of ACCM includes any manufactured building material that has more than one-tenth of 1% (>0.1%) asbestos content. The SMAQMD requires point counting of friable samples of ACM at concentrations of less than 10% to determine more accurately the content of asbestos and proper classification of the material for proper abatement and disposal requirements. Alternatively, materials may be presumed as ACMs. If the material is less than one tenth of 1%, the material is not regulated by the EPA however Cal/OSHA worker protection regulations apply if any asbestos is detected.

4.2 Lead Containing Paint/Materials

Personnel performing demolition activities that may disturb painted components or materials with concentrations of lead above the designated analytical detection limit should comply with all current Cal-OSHA regulations in order to minimize employee exposure. Cal-OSHA defines lead containing paint as a paint, which contains lead, regardless of the concentration. Currently, any proposed renovation/demolition is subject to the Cal-OSHA regulations (Title 8 CCR 1532.1 – Lead Exposure in Construction). The Cal-OSHA regulation defines specific training requirements, engineering controls and working practices for construction personnel subject to this standard.

Occupational exposure to lead occurring during construction work, including maintenance activities, painting, alteration, and repairs is subject to the Cal-OSHA Lead Exposure in Construction standard.

Construction work covered by Title 8 CCR 1532.1 includes any repair or renovation activities or other activities that disturb in-place lead-containing materials. Employers must assure that no employee will be exposed to lead at concentrations greater than 50 micrograms per cubic meter ( g/m3) averaged over an eight-hour period without adequate protection. The Cal-OSHA Standard also establishes an action level of 30 g/m3 which if exceeded triggers the requirement for medical monitoring.

Proper waste stream categorization is required for the disposal of all lead containing materials and painted construction debris with total lead content that exceeds 50 ppm. The debris should be classified as hazardous waste if lead waste concentrations exceed either the total lead concentration or soluble lead concentration regulatory limits. Total lead concentration is determined by Total Threshold Limit Concentration (TTLC). Soluble or leachable lead is determined by the Soluble Threshold Limit Concentration (STLC, California required test) and/or Toxicity Characteristic Leaching Procedure (TCLP) (Federal EPA required test). Regulatory limits characterize a lead waste as a hazardous waste if lead concentrations exceed 1,000 ppm by TTLC or 5 milligram per liter by STLC or TCLP.

The above overview is not intended to be inclusive of all potentially pertinent regulatory information. The relevant EPA and OSHA standards should be consulted prior to undertaking

Facilities | Environmental | Geotechnical | Materials 7 activities involving the demolition, renovation, or maintenance of surfaces coated with lead containing paints.

4.3 Refrigerants

The use, management, and release of ozone depleting substances used as refrigerants are regulated under the Clean Air Act (CAA) of 1990. Section 608 of the CAA forbids the venting of regulated refrigerants such as chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), and blended refrigerants. All regulated refrigerants associated with the building and equipment must be recovered prior to severing pressurized systems or disposal of equipment.

4.4 Universal Waste

Universal wastes are common wastes with hazardous properties that must be managed and have landfill disposal restrictions. Examples include electronic devices, batteries, and mercury containing equipment or lighting. Handling, transportation, and disposal is simplified under the universal waste regulation in the California Code of Regulations Title 22, Division 4.5 Chapter 11.

All materials in the buildings meeting the definition of the universal waste must be removed prior to demolition and handled, transported, and disposed through an appropriate vendor.

4.5 PCBs

PCBs are regulated by the EPA under 40 CFR 761. The production of PCBs has been banned since 1979 and may be present in electrical capacitors, sealants, hydraulic oils, and transformers commonly found in buildings. Materials with greater than 50 ppm PCB content are considered PCB contaminated waste while materials with greater than 500 ppm PCB are considered PCB containing.

PCB containing equipment and/or contaminated materials must be removed and disposed properly prior to demolition of a building. PCB containing lighting ballasts may be present in some lighting fixtures and must be verified by labeling. All PCB containing materials must be removed and disposed prior to building demolition.

It should be reemphasized that although reasonable efforts were made to survey accessible suspect materials, additional suspect but un-sampled materials could be located under existing building materials, inside walls, above ceilings, in isolated areas, in other concealed areas, or areas of the building outside of the defined survey area. Therefore, if suspect materials are encountered during abatement and demolition activities that do not appear to have been characterized as ACM or non-ACM, these materials must be assumed to be ACM until samples are collected and analyzed to prove otherwise. Any assumed material should be treated as asbestos or sampled to determine asbestos content before disturbing the material.

5.2 Lead Containing Paint/Materials

Terracon sampled fifteen (15) painted surfaces and five (5) bulk materials during the survey.

Sixteen (16) of the paint and building material samples were reported with lead content. A summary of sample locations and analytical results is below in Table II. Samples reported with “<” are below the laboratory analytical reporting limit for the sample submitted. The laboratory report is in Appendix C.

5.4 Other Hazardous Building Materials

Terracon visually assessed survey area for the presence of mercury containing products such as fluorescent light tubes, HID bulbs, mercury switches, thermostats, and compact fluorescent light bulbs. Mercury-containing tubes, bulbs, switches, and thermostats should be removed from the fixtures or equipment without breakage and packaged for mercury reclamation as a universal waste through an appropriate vendor prior to removal of any fixtures. Additionally, the building was inspected for the presence of exit signs and emergency lighting with backup batteries. No testing was performed.

Select lighting ballasts were inspected for labeling indicating the absence of PCBs. Ballasts observed were labeled as non-PCB ballasts. All ballasts should be inspected prior to disposal to verify the presence or absence of PCBs. Ballasts should be assumed to be PCB-containing unless specified by the manufacturer’s label as containing “No PCBs”. Table IV provides a summary and estimated quantity of materials observed within the survey area of the building. No testing was performed.
