3 Limited Hazardous Materials Survey Report Contra Costa College C-633 Performing Arts Center Seismic Upgrade 2600 Mission Bell Drive San Pablo, California 1. Executive Summary The following is a report of the limited hazardous materials survey conducted by Mike Bishop, California Certified Asbestos Consultant (CAC) and California Department of Public Health (CDPH) Sampling Technician and Steve Rogers Certified Site Surveillance Technician (CSST) and CDPH Sampling Technician, with RGA Environmental, Inc. (RGA). The survey was performed on December 22, 2015 in the Performing Arts Center of the Contra Costa College Campus located at 2600 Mission Bell Drive in San Pablo, California. The scope of the survey was to identify hazardous materials including asbestos containing materials (ACMs), lead containing paint, and lead containing ceramic tile with the potential to be impacted by the C-633 Seismic Improvement Project as depicted 100% Design Development drawing set dated November 12, 2015 and provided by the District. The survey area was limited to building areas and materials with the potential to be disturbed by the planned project. During the survey, twenty-three (23) homogenous suspect ACMs were identified. Two (2) of the homogeneous suspect ACMs tested positive for asbestos content. One (1) material was assumed to be asbestos containing. Two (2) painted finishes were sampled for potential lead content. None of the painted materials sampled were reported above the laboratory detection limit for lead. Two (2) ceramic tile glazes were sampled for the presence of lead. One (1) of the ceramic glazes was reported above the laboratory detection limit for lead. Table I summarizes the materials identified as ACMs. Table II summarizes the materials that were determined to be negative for asbestos content. Table III summarizes the lead concentrations of the materials sampled. Page 1

Scope of Work The scope of the survey was as follows: Inspect the survey area for the presence of suspect ACMs and lead-containing paints and materials with the potential to be impacted by the planned seismic improvement project. Collect a representative number of samples of suspect ACMs following the National Emissions Standard for Hazardous Air Pollutants (NESHAPs) protocol for sample collection for a renovation survey. Analyze asbestos bulk samples using polarized light microscopy (PLM) in accordance with EPA s July 1993 method for the determination of asbestos in bulk building materials - EPA 600/R-93/116. Collect paint chip samples of the primary painted surfaces and ceramic tile suspected to be lead containing for purposes of compliance with California Department of Occupational Safety and Health (DOSH) Lead in Construction Standard. Bulk samples and paint chips were analyzed at an accredited laboratory by Flame Atomic Absorption (AA) for Total Lead reported in parts per million (ppm). Ceramic Tile glazes were sampled by Total Threshold Lead Concentration TTLC analysis. Submit written report including analytical results, regulatory requirements, conclusions and recommendations. 3. Methods and Sampling Strategy Visual Inspection Accessible materials were visually inspected in the survey area using the methods presented in the federal Asbestos Hazard Emergency Response Act (AHERA) regulations (40 CFR, Part 763) as a guideline. AHERA was originally only applicable to schools, however state and federal Occupational Safety and Health Administration (OSHA) and Asbestos School Hazard Abatement and Reauthorization Act (ASHARA) have adopted the AHERA sampling methodology for all buildings subject to demolition or renovation. Bulk Sampling of Asbestos Bulk samples of all suspect ACM homogeneous materials were collected. A homogeneous material is defined as a surfacing material, thermal system insulation, or miscellaneous material that is uniform in color, texture and age of construction. Examples of homogeneous materials include: Pipe-insulation produced by the same manufacturer and installed during the same time period; Resilient flooring of identical color and pattern; Troweled on surfacing materials located in contiguous areas.

5 Limited Hazardous Materials Survey C-633 Performing Arts Center Seismic Improvement Contra Costa College San Pablo, California The survey area was visually inspected for the presence of suspect materials. As materials were identified, bulk samples were obtained with the aid of a coring device or other hand tool and placed into individual sampling bags. Each sample was given a discrete identification number and recorded on field notes as well as chain-of-custody forms. Refer to accompanying tables and appendices for details on material sample locations and results. Bulk samples were transported to EMLab P&K (EML) in San Bruno, California. Bulk Sampling of Suspect Lead Containing Materials Paint chip and/or suspected lead containing materials were collected using a hand scraper and were placed into individual plastic sampling containers. Each sample was provided a discreet sample number, which was recorded on a chain-of-custody form. Samples were transported to QuanTEM Laboratories (QuanTEM) in Oklahoma City, Oklahoma for analysis. Bulk Sample Analysis - Asbestos EML is accredited under the National Institute of Standards and Technology's National Voluntary Laboratory Accreditation Program (NVLAP) for determination of asbestos fibers in bulk materials. All samples were analyzed using polarized light microscopy (PLM) techniques in accordance with methodology approved by the U.S. Environmental Protection Agency (EPA). As set forth in the Code of Federal Regulations, 40 CFR Part 763, Appendix A to Subpart F, Section 1.2 and , the lower limit of reliability detection for asbestos using the PLM method is approximately one percent (1%) by volume. Cal-OSHA defines asbestos containing construction materials (ACCM) as those materials having asbestos content of greater than one tenth of one percent (>0.1%). When None Detected () appears in this report, it should be interpreted as meaning no asbestos was observed in the sample material above the reliable limit of detection for the PLM method. Note: under EPA assessment criteria, if a single sample of a homogeneous material tests positive for asbestos, all homogeneous materials within that building are considered to be asbestos containing. Bulk Sample Analysis Lead All paint samples were analyzed for lead content using the Flame Atomic Absorption spectroscopy in accordance to EPA Method SW B-7000B. When < appears in the lead sample report, it should be interpreted as meaning below analytical detection limit. Bulk ceramic glazing samples were analyzed by TTLC analysis. Page 4

8 Limited Hazardous Materials Survey C-633 Performing Arts Center Seismic Improvement Contra Costa College San Pablo, California 7. Regulatory Requirements Asbestos Building materials within the Performing Arts Center contain asbestos in concentrations greater than one tenth of one percent (0.1%). Impacting materials containing greater than 0.1% asbestos either through repair, maintenance, renovation or demolition activities triggers numerous regulations enforced by such agencies as OSHA (worker protection) and EPA (environmental exposure, transportation and disposal). Listed below are the regulations that apply if the materials are removed: Any individual who contracts to provide health and safety services relating to ACMs must be certified by Cal-OSHA as either a Certified Asbestos Consultant or a Site Surveillance Technician. The activities they are certified to provide include: conducting asbestos surveys; writing work plans or specifications for abatement; monitoring the work of abatement contractors; collecting air samples; and determining if the work area is safe for re-occupancy by non-asbestos workers. Regulation: Cal-OSHA 8 CCR 1529 (q)(1). If more than 100 square feet of materials that contain greater than 0.1% asbestos will be abated, they must be abated by a Cal-OSHA registered asbestos abatement contractor. Regulation: Cal-OSHA 8 CCR 1529 (R). ACMs that are classified by OSHA as other/miscellaneous materials are present. Removal of these materials is considered a Class II activity according to Cal-OSHA regulations. Work practices and engineering controls for Class II work are specified in Cal-OSHA 8 CCR 1529 (g) (7-8). If more than 100 square feet or 100 linear feet of friable ACM will likely be removed, the abatement contractor must notify the Bay Area Air Quality Management District ten (10) days prior to removing the material. Regulation: BAAQMD Regulation 11, Rule 2. Friable ACMs greater than 1% asbestos must be manifested, transported, and disposed of as hazardous waste in accordance with the Department of Toxic and Substances Control (DTSC), a division of Cal-EPA. DTSC regulates disposal of asbestos waste. DTSC issues U.S. EPA hazardous waste generator identification numbers. Page 7

9 Limited Hazardous Materials Survey C-633 Performing Arts Center Seismic Improvement Contra Costa College San Pablo, California Lead-Containing Materials Lead-containing ceramic tile glaze was identified during the survey. Impacting leadcontaining materials either through renovation or demolition activities triggers numerous regulations enforced by such agencies as OSHA (worker protection), EPA (environmental exposure, transportation and disposal), and Department of Public Health (DPH). Listed below are the regulations that apply if the lead containing materials are impacted during renovation activities: Federal OSHA as well as California OSHA regulates all worker exposure during construction activities that impact lead-containing materials. California OSHA enforces the Lead in Construction Standard in Title 8 CCR The scope covers construction work where employees may be exposed to lead during such activities as demolition, removal, surface preparation for re-painting, renovation, clean-up and routine maintenance. The OSHA specified method of compliance includes respiratory protection, protective clothing and equipment, housekeeping, hygiene facilities, medical surveillance, and training, among other requirements. California OSHA requires Department of Public Health Lead-Related Construction training if any lead related construction work in public buildings will exceed OSHA s permissible exposure limit (PEL) for lead. Disposal of all lead-containing paint and bulk materials is regulated at concentrations at or exceeding 1,000 ppm as stated in 40 Code of Federal Regulations (CFR) Part Land Disposal Regulations and Title 22, Division 4 Environmental Health of the California Administrative Code. Lead containing materials that exceed 50 ppm must be additionally analyzed to determine possible waste disposal restrictions with respect to lead. However, lead related work at any lead concentration is regulated under the OSHA statutes. 8. Recommendations to Implement Regulatory Requirements Asbestos Develop a performance abatement specification or work plan for the removal or impact of the ACMs identified in the survey that will likely be disturbed by the planned seismic improvement project. The purpose of an abatement specification is to clearly define the scope of work for more competitive and accurate bidding as well as to reduce the number of costly delays and change orders during the project. Conduct a pre-bid job-walk for abatement contractors in order to obtain the most competitive pricing. Page 8

10 Limited Hazardous Materials Survey C-633 Performing Arts Center Seismic Improvement Contra Costa College San Pablo, California Retain a Certified Asbestos Consultant or Site Surveillance Technician to provide onsite construction supervision of the asbestos abatement contractor to ensure utilization of proper work practices as stated in the work plan or specification. The Consultant also ensures that all local, state and federal regulations are followed and that the project remains on schedule. The on-site Consultant generates documentation of contractor work practices and training, and asbestos air sampling results. The on-site Consultant also ensures that all asbestos materials are removed by the abatement contractor and properly manifested. Request the Asbestos Consultant to collect a sufficient number of air samples on a daily basis to validate that the abatement contractor is not causing any releases of airborne asbestos fibers outside their work area. Request the Asbestos Consultant to visually review the work of the abatement contractor to verify that all the ACMs are abated. If the work areas pass the visual clearance, then final air clearance samples are collected to ensure that the area is safe for re-occupancy, or unregulated work. Request a final written report outlining all activities that transpired throughout the course of the abatement project. Lead-Containing Ceramic Glazing Lead containing debris that will be landfilled 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 containing waste as a hazardous waste if lead concentration exceeds 1,000 ppm by TTLC or 5 milligram per liter by STLC or TCLP. Solubility testing (STLC and TCLP) is required if the lead containing material exceeds 50 ppm by TTLC. We recommend the following actions prior to the start of renovation: Use only trained workers for disturbance of building components containing lead. All demolition work should be performed in accordance with the OSHA Lead in Construction Standard, Title 8 CCR Removal of lead-based paint should be performed by Department of Public Health Lead Related Construction trained workers. Worker exposure, environmental monitoring, and proper engineering controls should be implemented throughout the lead related work. Contractor should adhere to OSHA and other applicable state and local regulations for worker protection, hazard communications, work practices, engineering controls and proper waste disposal. Page 9

11 Limited Hazardous Materials Survey C-633 Performing Arts Center Seismic Improvement Contra Costa College San Pablo, California Proper waste stream categorization is required for the disposal of lead-containing materials such as paint debris, ceramic tile, and painted building components (intact) in accordance with the Department of Toxic Substance Control (DTSC). The disposal of lead-containing materials shall be coordinated with the landfill. 9. Limitations RGA Environmental Inc.
