Introduction The City of Piedmont retained Forensic Analytical Consulting Services, Inc. (FACS) to perform a comprehensive asbestos-containing materials (ACM) and lead-containing paint identification survey for the Community Pool and Carriage House in Piedmont, California. The survey was performed on March 12th and 16th, 2021 to identify the asbestos and lead content of materials and paint that would be impacted by demolition of the subject buildings. The FACS project management team consisted of Karina Garcia, Associate Project Manager, and Dave Brinkerhoff, Local Director. Ms. Garcia is a California Department of Public Health (CDPH) Certified Lead Sampling Technician (CDPH LRC-00003109) and Mr. Brinkerhoff is a California Division of Occupational Safety and Health (Cal/OSHA) Certified Asbestos Consultant (CAC 16-5645) and a CDPH Certified Inspector/Assessor (CDPH LRC-00002772). Mark Torres, Miguel Coyotl, and Anthony Aguilar conducted the site survey. Mr. Torres is a Cal/OSHA Certified Asbestos Consultant (CAC 18-6369) and a CDPH Certified Inspector/Assessor (CDPH LRC-00000582). Mr. Aguilar is a Cal/OSHA Certified Site Surveillance Technician (CSST 19-6525) and a CDPH Certified Sampling Technician (CDPH LRC-00001334). Mr. Coyotl is a Cal/OSHA Certified Site Surveillance Technician (CSST 18-6253) and a CDPH Certified Sampling Technician (CDPH LRC-00003703). FACS employee certifications are included in Appendix D. Site Characterization The two project buildings consisted of a one-story wood framed Pool House, and a two-story wood framed residence. The interior of the Pool House consisted primarily of painted wood and gypsum board walls, the floors were ceramic tile and concrete, and a painted wood ceiling. The roof of the Pool House was rolled roofing. There is a wood shed adjacent to the Pool House with a composite shingle roof. The interior of the Carriage House consisted primarily of painted wood and concrete walls, the floors were painted wood and concrete, and painted wood ceilings. Demolition is planned for the structures. Scope of Work FACS’ scope of work included a comprehensive bulk asbestos and lead paint survey, laboratory sample analyses, and report generation. This report contains the findings and recommendations from our inspection and the analytical results of samples submitted for laboratory analysis. The purpose of the survey was to identify, sample, and analyze suspect ACM and suspect lead-containing paint that may be disturbed in demolition of the subject buildings, within the limitations described below. Asbestos Survey Methodology Performing an asbestos survey prior to commencement of any demolition and renovation is regulated by the local air quality district. In the San Francisco Bay Area, an asbestos survey is required regardless of the building’s construction date. This asbestos survey was performed in accordance with the Bay Area Air Quality Management District (BAAQMD) Regulation 11, Rule 2. BAAQMD and Cal/OSHA recognize material with more than one percent (1%) asbestos to be ACM. However, Cal/OSHA also requires notification and registration of the contractor when working with materials containing more than one-tenth of one percent (0.1%) asbestos, and requires worker protection and specified work practices whenever materials containing any detectable levels of asbestos are to be disturbed. Our investigation consisted of the following:

• Visual inspection;



3 of 11

• Collection of samples of suspect ACM using the AHERA Survey protocol; • Submitting samples to SGS Forensic Laboratories, Inc. (SGSFL) located in Hayward, California

for analysis by Polarized Light Microscopy (PLM). SGSFL is accredited by the American Industrial Hygiene Association (AIHA) and by the NIST National Volunteer Laboratory Accreditation Program (NVLAP) for asbestos sample analysis; and

• Presenting analytical results, conclusions, and recommendations in a report that can be submitted to the BAAQMD.

The types, number, and locations of samples were determined based on available information about the subject project provided to FACS, visual observations, regulatory requirements, and other project management considerations. Lead Survey Methodology This survey was conducted by paint chip sampling. The lead survey was intended to assist with compliance with Cal/OSHA worker protection requirements. The lead survey was not a comprehensive lead-based paint survey as detailed in the "Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing" by The National Center for Lead-Safe Housing for HUD. Paint containing lead greater than 0.5% lead by weight (or 5,000 ppm) is considered lead-based paint (LBP) by CDPH and the Environmental Protection Agency (EPA), which regulate the disturbance of LBP. Paint with any detectable level of lead is considered lead-containing paint by Cal/OSHA and is regulated under Title 8 California Code of Regulations (CCR) Section 1532.1, Lead in Construction Standard. Since this paint chip survey sampled only representative components and not every individual component, the lead results are assumed to be the same on like components in the same general area of the representative component that was sampled. The paint chip samples were collected using a sharp scraper to remove all layers of paint down to the substrate material, taking care not to include the substrate in the sample. The detection limit is determined by factors including the size and matrix of each individual sample. Our investigation consisted of the following:

• Visual inspection; • Collection of samples of suspect lead-containing paint; • Submitting samples to SGSFL for analysis by atomic absorption spectrometry (Flame AAS) in

accordance with EPA Methods 3050B and 7000B. SGSFL is accredited by the AIHA Environmental Lead Laboratory Accreditation Program (ELLAP) and by the CDPH for lead analysis; and

• Presenting analytical results, conclusions, and recommendations in a report. The types, number, and locations of samples were determined based on available information about the subject project provided to FACS, visual observations, regulatory requirements, and other project management considerations. Findings and Recommendations Asbestos Survey Results The table below presents a summary of the asbestos findings for each of the homogeneous materials sampled in this survey.

Abbreviations/Acronyms ND – No Asbestos Detected NA – Not Applicable SF – Square Feet LF – Linear Feet CAT 1 Nonfriable – Category 1 Nonfriable Asbestos-Containing Material Asbestos was detected in the following material collected for this survey:

• Roof flashing in Pool House roof These results apply to all locations where the materials listed above are present in the project areas, not just to the sample locations. A table summarizing the laboratory analytical results for each of the bulk samples collected and submitted for asbestos analysis can be found in Appendix A of this report. Samples containing less than 10% asbestos (including Trace) must be further analyzed using the point count method to determine asbestos content more accurately or else must be considered >1% asbestos (ACM). FACS recommends:

1. Develop a specification for removal of ACM prior to disturbance by construction activities. 2. If other suspect asbestos-containing materials not previously tested are uncovered during

construction activities, those materials must be assumed to contain asbestos or must be sampled accordingly prior to their disturbance.

A detectable concentration of lead was reported in the Pool House green metal louvres, white concrete footing, gray metal rails, white gypsum wallboard walls, white metal pipes, off-white ceramic wall tiles, tan with wavy pattern ceramic wall tiles, light blue ceramic wall tiles, in the main pool white and black ceramic floor tiles, and in the Carriage House red concrete floor, and white concrete walls/footing. In the Pool House, all green wooden beams, white wood ceilings, and white wood walls should be considered to be lead-based paint based on these results. In the Carriage House, all white wood walls, white wood ceilings, white wood doors, red wood stairs, tan wood walls, cream stucco walls, cream concrete walls/footings, and brown wood windowsills should be considered to be lead-based paint based on these results. As required by the California Department of Public Health, Title 17, Article 16 Regulations, dated April 20, 2008, FACS will forward Form 8552 to CDPH notifying them of the absence of LBP in the areas tested at the subject property. A copy of the Form 8552 is contained in Appendix C. FACS recommends:

1. Current Cal/OSHA regulations (e.g. 8CCR 1532.1 “Lead in Construction” Standard) apply to all construction work where an employee may be occupationally exposed to lead. Therefore any work performed on a surface containing any amount of lead must comply with this regulation.

2. Any paint not represented by a result that is below the analytical limit of detection should be considered to contain lead and be treated as such until proven otherwise.

3. If other suspect lead-containing materials and/or paint not previously tested are encountered during demolition activities, those materials and/or paint must be assumed to contain lead or must be sampled accordingly prior to their disturbance.

4. Building records should indicate that a complete lead hazard evaluation of the building was not performed. The lead paint sampling was limited to assisting with Cal/OSHA compliance during demolition activities.

Asbestos Regulations The following is a summary of some current regulations that contain requirements related to building surveys for asbestos, worker protection from asbestos exposure, and asbestos as a hazardous waste. These summaries are not intended to be all-inclusive and do not contain every aspect of the regulations discussed. For detailed regulatory requirements in specific situations, FACS may be consulted, and the applicable regulations should be examined. Building Survey US EPA National Emission Standard for Hazardous Air Pollutants (NESHAP), 40 CFR Part 61 and Bay Area Air Quality Management District (BAAQMD) Regulation 11 Rule 2 Under NESHAP’s regulation, no visible emissions are allowed during building demolition or renovation activities that involve regulated asbestos-containing materials (RACM). For this reason, all buildings must be surveyed for ACM prior to demolition or renovation. BAAQMD, which implements NESHAP, must be notified prior to any building demolition even if no ACM are present. BAAQMD must be notified of most renovation projects that disturb RACM. All RACM must be removed from a building prior to demolition. Any disturbance (removal) of RACM during renovation or demolition must be performed according to BAAQMD regulations. RACM is (a) friable ACM; (b) Category I non-friable ACM that has or will become friable; (c) Category I non-friable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading; or (d) Category II non-friable ACM that may become or has become crumbled, pulverized, or reduced to powder by the forces expected to act on the material in the course of demolition or renovation.



9 of 11

Category I non-friable ACM are asbestos-containing packings, gaskets, resilient floor coverings, mastics, and asphalt roofing products. Category II non-friable ACM is any non-friable material not designated as Category I. Per BAAQMD, these products include transite board, pipe, and asbestos-cement products, plaster, stucco, and paint. Asbestos Hazard Emergency Response Act (AHERA), 40 CFR Part 763, Subpart E AHERA requires asbestos surveys and the development of Asbestos Management Plans for all of the nation's primary and secondary schools. The asbestos survey procedures of AHERA are considered the industry standard and are applied to all surveys performed by FACS unless otherwise specified. Samples are analyzed in accordance with EPA Method 600/R-93-116, using PLM with dispersion staining and visual area estimation to determine percent asbestos content. This method allows for identifying the primary types of asbestos used in building materials. All layers in a sample must be analyzed and reported separately. Samples (and layers of samples) containing <1 percent asbestos by PLM are reported as Trace. Samples containing <10 percent asbestos (including Trace) must be further analyzed using the point-count method to determine asbestos content more accurately or be considered >1 percent asbestos (ACM). Composite sampling, which may potentially reduce the total asbestos content of a material, is only permitted by EPA when sampling joint compound, tape, and gypsum wallboard according to Asbestos NESHAP Clarification Regarding Analysis of Multi-Layered Systems (40 CFR Part 61 FRL-4821-7). OSHA does not recognize composite sampling. Worker Protection California Assembly Bill AB3713, Health and Safety Code Division 20, Chapter 10.4, Section 25915-25924 Building owners, employers, lessees, etc., must notify tenants, employees, and contractors of the presence of asbestos in both friable and non-friable forms. Preventive maintenance activities must be developed and communicated to these parties. Notification is required 15 days after the identification of ACM and asbestos-containing construction materials (ACCM, >0.1 percent asbestos) in the building, and annually thereafter. Occupational Safety and Health Administration (OSHA) 29 CFR 1926.1101 and Cal/OSHA 8 CCR 1529 – Asbestos in Construction OSHA and Cal/OSHA require employers to implement specific work practices to protect workers from airborne asbestos exposure. Materials that contain any detectable amount of asbestos are regulated by OSHA and Cal/OSHA. Even building materials that contain low levels of asbestos (<1 percent) can potentially generate significant concentrations of airborne asbestos fibers when disturbed; therefore, control measures should be instituted that adequately address worker health and safety during planned renovation or demolition activities involving these materials. OSHA requires ACM to be categorized into Thermal System Insulation (TSI), Surfacing Materials, and ‘Other’ Materials for the purpose of determining job classification for abatement. TSI is ACM applied to pipes, fittings, boilers, breeching, tanks, ducts, or other structural components to prevent heat loss or gain. Surfacing Material is material that is sprayed, troweled, or otherwise applied to surfaces (such as acoustical plaster on ceilings; fireproofing materials on structural members; or other materials applied to surfaces for acoustical, fireproofing, and other purposes). ′Other′ materials are all ACM not categorized as TSI or Surfacing Material.

Hazardous Asbestos Waste US EPA National Emission Standard for Hazardous Air Pollutants (NESHAP), 40 CFR Part 61 and Bay Area Air Quality Management District (BAAQMD) Regulation 11 Rule 2 Hazardous waste in California is regulated by Cal/EPA, Division of Toxic Substances Control (DTSC). In California, friable ACM (>1 percent asbestos) waste is hazardous waste. EPA defines friable ACM waste as asbestos-containing waste but does not consider it to be “hazardous waste”. A waste site must be notified of the asbestos content of waste, including non-hazardous asbestos waste, prior to disposal. Lead Regulations and Guidelines The following is a summary of some current regulations that contain requirements related to worker protection from lead exposure and some regulations and guidelines related lead waste segregation, characterization, and disposal. These summaries are not intended to be all-inclusive and do not contain every aspect of the regulations discussed. For detailed regulatory requirements in specific situations, FACS may be consulted, and the applicable regulations should be examined. Worker Protection Cal/OSHA Lead in Construction Safety Standard (8 CCR 1532.1) The current Cal/OSHA Lead in Construction Safety Standard (8 CCR 1532.1) regulation applies to all construction work where an employee may be occupationally exposed to lead; therefore, work (including manual demolition, scraping, welding, etc.) performed on surfaces containing any detectable concentration of lead must comply with the standard, including exposure assessment monitoring (personal air sampling) to determine if the airborne lead exposure levels are within acceptable limits. For work involving a Cal/OSHA “trigger tasks” (such as sanding, cutting, torch cutting, etc.), workers must be protected during the initial exposure assessment, per the Cal/OSHA Lead Standard requirements, as if they were exposed above the Permissible Exposure Limit (PEL) until actual exposures are determined. With torch cutting, for example, this includes providing supplied air respiratory protection during the initial exposure assessment. Lead Waste Segregation, Characterization, and Disposal Loose and flaking paints should be scraped down to intact paint (and the resulting paint chips captured for disposal) prior to demolition. Only components with intact, well-adhered paint will then remain during demolition. The owner or removal/demolition contractor should conduct appropriate segregation of waste created during the removal or dismantling/demolition process and dispose of the different waste streams in accordance regulatory requirements based on appropriate testing results. Lead waste is considered a hazardous waste if the result of the Toxicity Characterization Leaching Procedure (TCLP) test exceeds 5 milligrams per liter (mg/l), under the Resource Conservation and Recovery Act (RCRA), 40 CFR 261, Appendix II. In California, a waste is also considered hazardous if the result of soluble lead content by a Waste Extraction Test (WET) is greater than 5 mg/l, or if the total lead content exceeds 1,000 milligrams per kilogram (mg/kg) in accordance with Title 22 of the CCR. When TTLC results are below 50 mg/kg, STLC/TCLP limits cannot be exceeded, so the waste is classified as general construction debris. Limitations The results of this survey do not apply beyond the planned demolition activities described above. Suspect asbestos- and lead-containing materials in areas not included in the scope of this survey should be assumed to be ACM and lead-containing, respectively, unless testing is conducted which determines

otherwise. The lead paint sampling was limited only to Cal/OSHA compliance during demolition activities and is not considered to be a complete lead hazard evaluation. If revisions to the demolition project are made that impact additional materials or areas, FACS should be contacted to review the changes and/or to conduct additional survey work to address potential impact to untested materials. This investigation is limited to the conditions and practices observed and information made available to FACS. The methods, conclusions and recommendations provided are based on FACS’ judgment, expertise and the standard of practice for professional service. They are subject to the limitations and variability inherent in the methodology employed. As with all environmental investigations, this investigation is limited to the defined scope and does not purport to set forth all hazards, nor indicate that other hazards do not exist.
