3 Asbestos and Lead Pre-demolition Survey Report February, 2015 Hinkel Clubhouse Berkeley, CA 1.0 Introduction The purpose of this report is to provide the findings of an asbestos and lead survey Acumen Industrial Hygiene, Inc. (Acumen) conducted at the above referenced facility (John Hinkel Park Clubhouse). It is understood that the Hinkel Clubhouse is scheduled for demolition, due to a major fire, which destroyed the west portion of the structure. Mr. Paul Spillane, CIH, CAC, conducted the investigation at the building(s) on February 3, The inspection was limited to accessible areas of the building(s), which was restricted due to safety concerns. The objectives of this investigation were as follows: To identify regulated asbestos containing materials (RACMs), defined by Bay Area Air Quality Management District (BAAQMD). RACMs and Category I and II materials that will be rendered friable will need to be removed prior to building demolition. To identify other asbestos containing materials that would require compliance with Cal- OSHA asbestos regulations and waste disposal regulations. To identify lead containing paints and ceramic tiles that would require removal prior to demolition to comply with Cal-EPA Department of Toxic Substances Control (DTSC) hazardous waste disposal regulations. Handling of lead containing materials also has Cal-OSHA lead requirements. The evaluation of paints and ceramic tiles was not intended to be either a lead inspection or a lead hazard evaluation as defined by California Department of Public Health (17CCR35001 et seq). To identify other hazardous building materials that would require removal prior to demolition to comply with Cal-EPA DTSC hazardous waste disposal regulations. These materials include universal hazardous wastes including mercury, polychlorinated biphenyls (PCBs) and Freon (chlorofluorocarbons, CFCs). Although not the focus of our survey, we noted other stored universal hazardous wastes such as containers of pesticides and paint. 2.0 Summary of Investigation Asbestos and Lead Containing Materials Inspection Methods The inspection consisted of a walkthrough of accessible areas at the site to identify and sample suspect ACM and lead containing materials. Acumen s standard survey protocol is to conduct asbestos inspections in three steps: conducting a review of existing building survey records and/or drawings; physically surveying structure for suspect materials; and documenting our findings in a written report format. There were no previous survey documents of the building for review. Asbestos and lead bulk samples are physically collected by taking a small core section of the suspect asbestos material using hand tools. Paints are manually collected from architectural components such as walls, and trim. Paints on mechanical components or fixtures are not typically sampled unless requested. Paints are sampled by physically collecting a paint chip and placing the sample into a clean container. Acumen noted significant factors of suspect ACM including conditions, homogeneity, locations, quantity, potential for damage or disturbance, and friability. Friability describes the ability of a material to be crushed or crumbled, when dry, into a powder using hand pressure. Where suspect materials were noted, bulk samples were collected. At the building, Acumen collected samples of various suspect ACM and lead Page 1 of 8

4 Asbestos and Lead Pre-demolition Survey Report February, 2015 Hinkel Clubhouse Berkeley, CA containing materials. We collected twenty-one (21) total asbestos bulk samples, one bulk-paint sample and one bulk lead sample from ceramic tile. Samples were given a unique identification number and submitted with our chain of custody forms to Micro Analytical Laboratories, Inc. (Emeryville, CA) for analysis. Micro Analytical Laboratories, Inc. is accredited to analyze asbestos and lead samples. Micro holds the National Institute of Standards and Technology (NIST)/ National Voluntary Laboratory Accreditation Program (NVLAP) accreditation for Transmission Electron Microscopy (TEM) (ISO/IEC 17025:1999); Polarized Light Microscopy (PLM) (EPA-600/M , ISO 9002:1994) Airborne Asbestos, Lab Code # and; NIST (NVLAP), Bulk Asbestos, Lab Code ; and AIHA ELLAP Industrial Hygiene Laboratory Program, # Lead samples were analyzed by Flame Atomic Absorption (FLAA) or Total Threshold Limit Concentration (TTLC) in accordance with EPA method SW 846. Asbestos samples were analyzed by polarized light microscopy (PLM) per U. S. Environmental Protection Agency (EPA) method 600/R-93/116, The laboratory reports are shown as Appendix A. This analytical method identifies the type(s) of asbestos present in the sample and its corresponding percent concentration(s). The reliable limit of quantification of this method is 1% asbestos by volume. Please refer to the Appendix A for sample chain of custody forms and analytical reports. 3.0 Findings and Discussion The subject site was originally constructed pre-1918 as a rustic red-wood cabin with a stone fireplace by John Hinkel. The building is constructed of red-wood framing and red-wood siding on a concrete mudsill and pier-block foundation (Photo 1). The building consists of great room with a high ceiling, a kitchen and storage on the main-floor. At the ground floor there are several storage rooms, two restrooms and a mechanical room. There is one antique stove that contains asbestos padding (assumed ACM, Photo 2). The duct insulation and seam tape both contain up to 40% asbestos and these were severely damaged in the furnace room (Samples NEM A, NEM B, NEM C, NEM A and NEM B, Photo 3). There is a gas water heater at the ground floor with un-insulated galvanized metal pipes. Acumen sampled an unknown box of white powder in the furnace room and some of the debris, which tested negative for asbestos (Samples NEM A, NEM B). Additional analysis is required on the box of powder (about 3 cubic feet, Photo 4), and the debris pile is assumed to be contaminated with friable asbestos due to the ducting (Photo 5). Fortunately, the exterior paints and interior walls/ceilings do not contain asbestos. Acumen sampled paint, plaster with skim coating and drywall with taping mud, and these were none-detected (Samples NEM A, NEM A, NEM B, NEM A, NEM A and NEM C). The paint however contains lead, up to 620 parts per million (ppm) in the exterior brown paint (Sample NEM15129-Pb01). The lower floor restrooms have 1x1 ceramic floor tiles with brown mastic/grout which also do not contain asbestos, but also contains 110 ppm lead (Samples NEM A, and NEM15129-Pb02). Baseboard mastics sampled also do not contain asbestos (Sample NEM A). The roofs are plywood covered with a tar-paper and shingle roofing system that do not contain asbestos (Samples NEM A). There is one section of asbestos flue pipe that extends from the furnace room to the roof (about 20 linear feet, Photo 6). We also sampled the imported rock and foundation concrete, Page 2 of 8

5 Asbestos and Lead Pre-demolition Survey Report February, 2015 Hinkel Clubhouse Berkeley, CA which do not contain asbestos (Samples NEM A, NEM B, NEM C and NEM A). Universal hazardous wastes are also present in the building that will require removal prior to building demolition. These would include one mercury thermostat, and seven fluorescent lighting fixtures, which may contain polychlorinated biphenyls (PCBs) and mercury vapor. We inspected several fluorescent lighting ballasts and 5 of the 7 do not contain labeling to exclude PCBs (Photo 7). Stored chemicals included herbicides (about one gallon), ammonia (2 gallons), oil/grease (<1 gallon), several cans of spray paint, a metal gasoline container and the 3 cubic feet of unknown powder (mentioned above). Additional universal hazardous wastes may be present buried under debris. 4.0 Summary of Findings 4.1 Asbestos Related Findings The results of this investigation sampling determined that ACM materials are present at the following locations. These materials must be removed prior to demolition. Asbestos Containing Materials Antique stove padding (assumed ACM, Photo 2): This is located in the ground floor storage room. We estimate about 4 square feet will need to be abated. The material is considered RACM. Duct insulation and seam tape (Photo 3): This is located in the furnace room and extends through the crawl space and ground floor storage room. We estimate about 60 linear feet will need to be abated. The material is considered RACM. Crawl Space and Furnace Room Debris (Photo 5): This is located in the furnace room and the crawl space. We estimate about 300 square feet of debris, which is considered RACM. The waste may not be hazardous waste (if <1% as a composite), but will still require handling per EPA regulations as RACM. Asbestos-cement flue pipe that extends from the furnace room to the roof (Photo 6): There are about 20 linear feet that extend from the furnace room to the roof. The material is considered Category II non-friable ACM. Materials that were sampled and do not contain asbestos include the following: Exterior Brown Paint 1x1" Brown Ceramic Floor Tile Ceramic Tile Mastic/ Mortar/ Grout Plaster, Skim Coating and Paint Drywall/Taping Mud and Paint Brown Baseboard Mastic Unknown White Powder Roofing Shingle and Tap paper Exterior Decorative Stone Foundation Concrete 4.2 Lead Related Findings The results of this investigation determined that lead containing materials are present. Lead containing paint must be stabilized prior to demolition. Lead containing materials require separate disposal. The investigation found the following lead-containing paints/materials are present: Exterior Brown paint on siding: 620 ppm (Sample# NEM15129-Pb01) Ground Floor Women s and Men s Rooms: Brown 1x1 Ceramic Tile: 110 ppm (Sample# NEM15129-Pb02) Page 3 of 8

6 Asbestos and Lead Pre-demolition Survey Report February, 2015 Hinkel Clubhouse Berkeley, CA There are two consequences associated with the presence of lead containing paints/ceramic tiles in the building. The first is that any construction work that disturbs these materials (including demolition) will need to be conducted in accordance with Cal-OSHA's lead in construction regulations (8CCRI532.l). These regulations apply to any material that contains detectable amounts of lead. In theory, this should not pose a significant problem as this regulation has been in effect since The deteriorated paint results suggest that most coatings contain lead. Cal-OSHA's lead in construction standard (8 CCR ) requires a contractor whose work involves disturbing lead containing materials to develop and implement a lead compliance plan, conduct employee exposure assessment to determine appropriate protective measures, including medical surveillance and personal hygiene facilities, and to provide employee training on the hazards of lead related work. Note that lead related work in public building that exceeds Cal-OSHA's permissible exposure limit requires that the training be accredited lead worker training. Cal-OSHA notification 24 hours in advance of removal work would not be required because the paint tested contains less than 0.5% lead. The written lead compliance plan would essentially acknowledge the presence of lead and would describe procedures to minimize airborne lead exposures (e.g. use of dust control, clean up debris daily with a HEPA vacuum, and use good personal hygiene procedures, etc.) consistent with either assumed or known airborne lead exposures. The second consequence associated with the presence of lead in deteriorated paint/ceramic tile is that they may meet Cal-EPA's criteria for hazardous waste classification. These would need to be removed and disposed of separately from other building debris. Cal-EPA's criteria for hazardous waste classification based on lead content are that the waste must contain more than 1,000 parts per million of lead. Fortunately this was not the case with paints/tiles at the building. Wastes that contain less than 1,000 ppm but more than 50 ppm should be analyzed for soluble lead content. If the soluble lead content exceeds 5 mg/liter, then the waste would be classified as a hazardous waste. Alternatively, the deteriorated paints that contain less than 1,000 ppm lead could be handled as hazardous waste instead of being re-tested. As indicated above lead-containing paint or materials were found on many of the areas tested. Areas of flaking paint should be stabilized before demolition. Lead-containing materials at a concentration above 50 ppm would require segregated disposal. We estimated the following quantities: Brown deteriorated paint (exterior walls ): about 1,000 square feet; Brown Ceramic Tile: about 180 square feet (two restrooms). 4.3 Universal Hazardous Wastes: The DTSC has adopted regulations (SB 20 Electronic Waste Recycling Act) for the handling of universal waste or E-Waste. This category is a subset under all hazardous wastes. Universal wastes encompass a variety of electronic devices (including fluorescent lamps, light ballasts, mercury thermostats, cathode ray tubes, batteries, etc.) that usually contain mercury, lead, cadmium, chromium and copper. These materials are considered toxic and are banned from landfill disposal. These materials should be collected and recycled prior to demolition in lieu of disposal. Fluorescent light tubes/ mercury thermostats should be carefully removed without breaking and packaged for recycling. At a minimum the universal hazardous wastes present include: One mercury thermostat; Page 4 of 6

7 Asbestos and Lead Pre-demolition Survey Report February, 2015 Hinkel Clubhouse Berkeley, CA Seven fluorescent lighting fixtures, plus about a dozen stored lighting tubes; Fluorescent lighting ballasts (which do not exclude PCBs, Photo 7); Stored chemicals including herbicides (about one gallon), ammonia (2 gallons), oil/grease (<1 gallon), several cans of spray paint, a metal gasoline container and the 3 cubic feet of unknown powder (mentioned above). Additional universal hazardous wastes may be present buried under debris. 5.0 Recommendations for ACM/LBP During Building Demolition (or Renovations) 1. Notify potential renovation contractors of the presence of ACM in the building. Disturbance of ACM requires special training and procedures. BAAQMD regulations require that ACM be properly removed and disposed, prior to demolition or renovation where they would be disturbed. A Cal-OSHA registered asbestos contractor is required and this work requires notification to the BAAQMD 10-days prior to removal, since RACM is removed (duct wrap, tape and crawl space debris). 2. Prior to building demolition, have a competent lead-abatement contractor or licensed hazardous materials contractor stabilize deteriorated leaded paints (e.g. exterior walls). 3. Notify potential renovation or demolition contractors of the presence of lead-containing paints in the building. Disturbance of these materials requires compliance with Cal-OSHA s lead in construction regulation. 4. The fluorescent light fixtures and mercury thermostats in the building will require dismantling and recycling. The ballasts likely contain PCBs, which require disposal as hazardous wastes. 5. The hazardous materials contactor will need to remove all stored chemicals. Additional chemicals may be present, hidden in the substantial debris. 6. Although there is no regulatory requirement for it, it would be advisable to develop either a work plan or specification for the handling of asbestos and leaded paints during abatement. The demolition contractor can recycle some universal hazardous wastes, (such as lighting tubes and hydraulic oils), if specifically included in their work scope. 6.0 Conclusions Acumen has completed an asbestos and lead survey of John Hinkel Clubhouse in Berkley, California. This investigation found asbestos thermal system insulation and debris, one antique stove and an asbestos flue pipe. Lead containing paint will need to be stabilized and ceramic tiles removed. Universal hazardous waste will also need to be separated and removed. Demolition that disturbs leaded paint left in place will require actions to comply with Cal-OSHA lead regulations. If the building is not demolished, the lead and asbestos that would not be abated at this time would need to be managed under an O&M program, (if the building is to remain in use).
