3 Pre-Demolition Hazardous Materials Survey Report Contra Costa Community College Health and Science Building 2600 Mission Bell Drive San Pablo, California 1. Executive Summary The following is a report of the pre-demolition hazardous materials survey conducted by Remington Caldwell, Certified Asbestos Consultant (CAC) and California Department of Public Health (CDPH) Inspector/Assessor and John Alexander, Certified Asbestos Consultant (CAC) and California Department of Public Health (CDPH) Inspector/Assessor with RGA Environmental, A Terracon Company (RGA). The survey was performed on April 3, 18 and May 9, 2017 at the Health and Science building located at 2600 Mission Bell Drive, San Pablo, California. The survey scope included the interior, exterior, and all roof levels of the Health and Science building and the attached corridor connecting to the vacant Liberal Arts building. A total of thirty-four (34) suspected asbestos containing materials (ACMs) were identified and sampled throughout the interior, exterior, and roof of the captioned structure and attached corridor connector. Seven (7) of the materials were confirmed to be positive for asbestos content upon laboratory analysis. Due to the current occupancy, six (6) suspect materials were assumed to be asbestos containing. Three (3) painted surfaces and one (1) window sealant were sampled for potential lead content. Three (3) of the painted surfaces were found to contain lead content above the laboratory detection limit. The window sealant sample was found to contain lead above the laboratory detection limit. One (1) of the paint samples were found to contain lead in concentrations exceeding 5,000 parts per million (ppm), the threshold for designation of leadbased paint. Due to the occupancy, four (4) suspect ceramic tiles were observed and assumed to be lead containing. Three (3) suspect exterior sealants were sampled for potential polychlorinated biphenyl (PCB) content. PCBs were reported in two (2) of the samples. One (1) roof mounted mechanical unit was observed on the main roof level of building. The unit was marked as containing R-22 refrigerant, a hydrochlorofluorocarbon (HCFC) based refrigerant. One (1) chilled water cooler was identified in the first floor hallway. Page 1

4 Pre-Demolition Hazardous Materials Survey Report Health and Science Building 2600 Mission Bell Drive San Pablo, California Mercury containing fluorescent light tubes and compact fluorescent lamp (CFL) bulbs were present throughout the interior and exterior of the building. Four (4) high intensity discharge (HID) fixtures were observed on the exterior of the building. Representative lighting ballasts inspected in the building were labeled as containing No PCBs. All ballasts not specifically labeled as No PCBs are assumed to contain polychlorinated biphenyls (PCBs). Seven (7) exit signs with backup batteries were confirmed present on the ground and first floor, however, no tritium exits signs were observed. One (1) emergency egress lighting unit with backup batteries was observed within the structure. 2. Scope of Work The scope of the survey was as follows: Inspect the subject property for the presence of suspect ACMs, lead-containing paint and materials, mercury-containing products, PCB lighting ballasts and sealants, chlorofluorocarbon (CFC) or hydrochlorofluorocarbon (HCFC) containing equipment, tritium exit signs, and universal wastes. Collect samples of suspect ACMs following a National Emissions Standards for Hazardous Air Pollutants (NESHAPS) protocol for sample collection for a demolition survey. Asbestos bulk samples will be analyzed using polarized light microscopy (PLM) in accordance with the EPA s July 1993 method for the determination of asbestos in bulk building materials - EPA 600/R-93/116. Collect bulk paint chip samples of primary painted surfaces and other materials suspected to be lead containing. Bulk samples will be analyzed at an accredited laboratory by Flame Atomic Absorption (AA) for Total Lead reported in parts per million (ppm). Collect bulk samples of suspect PCB containing sealants on exterior of buildings if present. PCB samples will be analyzed by analytical method SW8082. Submit written report including analytical results, regulatory requirements, and conclusions. 3. Methods and Sampling Strategy Visual Inspection Accessible building materials on the interior and exterior of the structure were visually inspected 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 Reauthorization Act (ASHARA) have adopted the AHERA sampling methodology for all buildings subject to demolition or renovation.

5 Pre-Demolition Hazardous Materials Survey Report Health and Science Building 2600 Mission Bell Drive San Pablo, California Visual Inspection for Mercury Containing Materials Approximately two hundred and eighty (280) fluorescent light tubes (mercury containing) were identified in the building. Approximately Ten (10) CFLs and (4) HID bulbs were noted on the interior and exterior of the building. All of the light tubes, HID, and CFL bulbs should be removed without breakage prior to removal of fixtures and managed as a universal waste. Visual Inspection for PCB-containing Equipment and Materials Approximately one hundred and sixty-five (165) fluorescent light ballasts were identified on the interior of the structure. Ballasts observed were labeled as No PCBs. All ballasts should be inspected prior to disposal to verify the presence/absence of PCBs. Ballasts should be assumed to be PCB-containing unless specified by the manufacturer s label as containing No PCBs. Visual Inspection for Tritium-containing Exit Signs Seven (7) exit signs with backup batteries were identified on the ground and first floor levels. Exit sign were lit with either incandescent or LED bulbs. No tritium-containing exits signs were observed within the building. Visual Inspection for CFC Containing Equipment One roof-top mechanical system was observed on the main roof level. The refrigerant type was confirmed as R-22 on the identification labels on the exterior of the unit. The R-22, an HCFC refrigerant, should be captured from the unit prior to disposal or disconnecting close-loop pressurized lines. A chilled water cooler was observed in the first floor hallway. The refrigerant type could not be determined. No testing was performed. Bulk Sampling of Asbestos Bulk samples were collected of homogeneous suspect ACMs from the on the subject building. A homogeneous material is defined as a surfacing material, thermal system insulation, or miscellaneous material that is uniform in color, size, texture and age of construction. Examples of homogeneous materials include: Resilient flooring of identical color and pattern; Troweled on surfacing materials located in contiguous areas; Acoustical ceiling material produced by the same manufacturer and installed during the same time period. The building 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 discreet 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. Page 3

6 Pre-Demolition Hazardous Materials Survey Report Health and Science Building 2600 Mission Bell Drive San Pablo, California Bulk Sample Analysis - Asbestos Bulk samples were analyzed by EMLab P&K (EML) in Henderson, Nevada and Arvado, Colorado. EML is accredited under the National Institute of Standards and Technology's National Voluntary Laboratory Accreditation Program (NVLAP). 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 areas of that homogeneous material are considered to be asbestos containing. Bulk Sampling of Lead Paint and Suspect Bulk Materials Paint chip and bulk samples were collected using a hand scraper or chisel 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. The samples were transported under chain-of-custody procedures to QuanTEM Laboratories (QuanTEM) in Oklahoma City, Oklahoma. Please refer to Table III for details on sample locations and sample results. All samples were analyzed for lead content in accordance to EPA Method 7000B. 4. Asbestos Results During the survey, a total of thirty-four (34) suspected asbestos containing materials (ACMs) were identified. Seven (7) materials were confirmed positive for asbestos content upon laboratory analysis. Six (6) suspect asbestos-containing material were assumed to contain asbestos. The confirmed and assumed asbestos containing materials are listed in Table I below.

Conclusions and Recommendations Based upon the survey results, RGA concludes the following: Asbestos was detected in various materials including floor tile mastics, cove base mastics, drywall finishing compounds, and exterior stucco. The grout/mastics associated with the ceramic tiles in the restrooms, mechanical pipe valve flange gaskets, and 9 grey vinyl floor tile and associated mastics are assumed to contain asbestos. If additional suspect materials that have not been characterized as ACM or non-acm in this report are discovered during demolition, these materials should be assumed to Page 7

10 Pre-Demolition Hazardous Materials Survey Report Health and Science Building 2600 Mission Bell Drive San Pablo, California contain asbestos and be treated accordingly until proven otherwise by appropriate sampling and laboratory analysis. Lead was detected above the laboratory detection limit in the painted surfaces tested. One (1) of the painted surfaces was found to contain lead in concentrations exceeding 5,000 parts per million the threshold for lead based paint. Four (4) ceramic tile samples were assumed to be lead containing. Mercury-containing fluorescent-light tubes, HID bulbs, and CFL bulbs and were identified throughout the survey area. Mercury-containing tubes and bulbs 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. Suspect PCB-containing ballasts associated with the fluorescent lights were observed throughout the structures. Each ballast label should be inspected for the phrase No PCBs prior to disposal. Ballasts not labeled as such should be assumed to contain PCBs. PCB ballasts should be removed from fixtures and disposed of as PCB-containing materials prior to disposal of the fixtures. One roof-top HVAC system was confirmed to contain R-22 refrigerant. One (1) chilled water-fountain was observed in the 1 st floor corridor. The refrigerant type for the waterfountain could not be confirmed. 8. Regulatory Requirements Asbestos Impacting materials containing greater than 0.1% asbestos either through repair, maintenance, 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, the materials must be abated by a Cal-OSHA registered asbestos abatement Page 8

11 Pre-Demolition Hazardous Materials Survey Report Health and Science Building 2600 Mission Bell Drive San Pablo, California 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). Removal of friable ACMs greater than 100 square feet or 100 linear feet requires notification of the Bay Area Air Quality Management District ten (10) working days in advance of intended removal. 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. Lead Impacting lead materials or lead-containing paint either through repair, maintenance, 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 lead regulations that apply: There are presently no federal, state or local regulations limiting the concentration of lead in public sector buildings, however several regulations established for the private sector as well as for government subsidized housing are used industry wide as guidelines for assessing exposure to lead. The Consumer Product Safety Commission (CPSC) has set a maximum limit of 90 ppm in paint used for residential purposes. The Department of Housing and Urban Development (HUD) requires abatement of lead hazards involving paint in concentrations exceeding 5,000 ppm. 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 milligrams per liter by STLC or TCLP. Page 9

12 Pre-Demolition Hazardous Materials Survey Report Health and Science Building 2600 Mission Bell Drive San Pablo, California Federal OSHA as well as California OSHA regulates all worker exposure during construction activities that impact lead-containing paint. 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. 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. Universal Waste and Other Potential Hazardous Materials Universal waste are common wastes with hazardous properties that must be managed and have landfill disposal restrictions. Example of universal waste 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. Refrigerants The use, management, and release of ozone depleting substances used as refrigerants are regulated under the Clean Air Act (CAA) of Section 608 of the CAA forbids the venting of regulated refrigerants such as CFC, HCFC, blended refrigerants. All regulated refrigerants associated with the buildings and equipment must be recovered prior to severing pressurized systems or disposal of equipment. Page 10
