Ninyo & Moore | Union City Youth Bike Shop, 33629 Mission Boulevard, Union City, California | 404370004 | May 27, 2025 1 1 INTRODUCTION
Ninyo & Moore was retained by the City of Union City Public Works Department (UCPWD/Client) to conduct a hazardous building materials survey (HBMS) at the Union City Youth Bike Shop located at 33629 Mission Boulevard in Union City, California (Figure 1). Our services included the performance of suspect asbestos-containing materials (ACMs) and suspect lead-containing materials (LCMs) surveys and a review and quantification of miscellaneous hazardous building materials (potential mercury-containing thermostats/switches, PCB-containing items [transformers, light ballasts, etc.], fluorescent light tubes, exit signs, air conditioning units, and FreonTM-containing refrigeration systems) within the site building. For the purposes of this assessment, LCM refers to both lead-based paint (LBP), as defined by the California Department of Public Health (CDPH) and U.S. Department of Housing and Urban Development (HUD) and other potential LCMs (including ceramic tile).
The survey sampling activities were performed in accordance with established guidelines for the assessment of ACM and LCM and are based upon conditions at the site building at the time of the surveying/assessment activities. Our objective and scope of work for the sampling activities are presented below.

2 OBJECTIVE AND SCOPE OF SERVICES
The purpose of this study is to provide information regarding current conditions within the site building related to the proposed renovation of the building. Ninyo & Moore personnel performed the following services:
Ninyo & Moore | Union City Youth Bike Shop, 33629 Mission Boulevard, Union City, California | 404370004 | May 27, 2025 2 • Visual reconnaissance of the site building to document homogeneous areas of hazardous building materials and locate suspect ACM and LCMs.
• Collection of 24 bulk samples of suspect ACMs and submittal of these samples to a certified, independent laboratory for analysis of asbestos content via polarized light microscopy (PLM/EPA 600/R-93/116 Method).
• Collection of 13 suspect LCM samples and submittal of these samples to a certified, independent laboratory for analysis of lead content (EPA Method SW-846 3050B/7000B). • Visual assessment and quantification of potential mercury-containing thermostats/switches, PCB-containing items, fluorescent light tubes, exit signs, smoke detectors, air conditioning units, and FreonTM-containing refrigeration systems. • Preparation of this limited HBMS report, which presents our data and summarizes the assessed building materials. The report includes a site description, laboratory testing information, findings, conclusions, and recommendations, sample/site location maps, tables summarizing the building materials assessed, and the estimated quantities of identified materials.
3 SITE DESCRIPTION
The Union City Youth City Bike Shop building encompasses approximately 2,000 square feet (SF), is of wood/concrete construction with exterior concrete walls with rolled-on roofing materials.
Workshop areas, a lobby, a bathroom, a garage and storage areas are located within the site building. Finishes for the lobby, workshops, bathroom, and storages include gypsum wallboard/concrete walls, concrete flooring, and wood ceilings. 4 PHYSICAL LIMITATIONS
No physical limitations were encountered within the site building during our sampling procedures.
Underground utilities, such as suspect cementitious water lines or suspect insulated/coated gas or electrical lines were not assessed during these survey activities. If additional suspect materials and/or surfaces are encountered during site building demolition/renovation activities that have not been assessed, they should be assumed to be asbestos, lead and/or PCB-containing and handled accordingly, or should be sampled and analyzed to assess whether they are asbestos, lead and/or PCB-containing.
5 SAMPLE COLLECTION AND ANALYSES
On May 1, 2025, the site building was assessed for the presence of ACMs, LCMs and miscellaneous hazardous building materials. The ACM and LCM surveys followed United States Environmental Protection Agency (EPA) guidelines, or industry standards, within the limitations of the scope of this assessment. Survey activities are discussed below.
Ninyo & Moore | Union City Youth Bike Shop, 33629 Mission Boulevard, Union City, California | 404370004 | May 27, 2025 3
5.1 Asbestos Survey
A preliminary visual assessment and bulk sampling survey of suspect ACMs were performed by Ninyo & Moore personnel. Representative samples of suspect ACMs were collected after identification of homogeneous sampling areas (areas in which the materials are consistent in color, texture, construction or application date, and general appearance). Each homogeneous area was observed for material type, location, condition, and friability. Representative samples were collected from each area (except from areas that were inaccessible). Samples were collected using EPA-recommended sampling procedures.
A total of 24 bulk suspect asbestos samples were collected and analyzed. Building materials that were sampled and analyzed for the presence of asbestos are presented in Table 1.
After collection, the suspect ACM samples were transferred to EMSL Analytical, Inc., (EMSL) of San Leandro, California for analysis. EMSL is a laboratory accredited in the National Voluntary Laboratory Accreditation Program (NVLAP) for bulk asbestos fiber analysis. The samples were analyzed for the presence and quantification of asbestos fibers, using polarized light microscopy with dispersion staining (PLM/ds), in general accordance with EPA Method 600/R-93/116. The lower limit of reliable detection for asbestos using the PLM method is approximately 1 percent by volume. Currently, the EPA and the State of California stipulate that materials containing more than 1% asbestos constitute an ACM and the State of California stipulates that a material containing greater than 0.1% asbestos constitutes an asbestos-containing construction material (ACCM). Building materials that were sampled and analyzed for the presence of asbestos are presented in the attached Table 1, and the locations from which bulk asbestos samples were collected are shown on Figures 2 and 3. Materials in which no asbestos was detected are defined in Table 1 as “ND” (for “None Detected”) in the “Asbestos Content” column. Copies of the laboratory analytical reports and chain-of-custody records for suspect ACMs are presented in Appendix B. ACMs reported in the Ninyo & Moore survey are listed in Section 6.1 below.
5.2 Lead-Containing Materials Survey
After collection, the suspect LCM samples were also transferred to EMSL for analysis of total lead content by Flame Atomic Absorption Spectroscopy (Flame AAS/SW 846 3050B/7000B). EMSL is an American Industrial Hygiene Association-accredited Environmental Lead Laboratory (AIHA ELLA). Currently, the EPA stipulates what concentrations of lead in non-volatile components of surface coatings or materials indicate whether a material is considered to be lead-containing. The EPA stipulates that paint containing an amount equal to (or in excess of) 1 milligram per square centimeter (1.0 mg/cm2
), or more than half of one percent (0.5%) by weight (or 5,000 milligrams per kilogram [mg/kg]), constitute a lead-based paint (LBP). Coatings with any detectable amount of reported lead would be considered lead-containing paint (LCP).
Ninyo & Moore | Union City Youth Bike Shop, 33629 Mission Boulevard, Union City, California | 404370004 | May 27, 2025 4 The analytical results associated with paint chip samples collected from the site building are summarized in Table 2 and copies of the laboratory analytical report and chain-of-custody record are presented in Appendix C. Sample locations are shown on Figures 2 and 3.
5.3 Miscellaneous Hazardous Building Materials Survey
A visual assessment of potential mercury-containing thermostats/switches, PCB-containing items (transformers, light ballasts, etc.), fluorescent light tubes, exit signs, smoke detectors, air conditioning units, and FreonTM-containing refrigeration systems was performed at the site building. Materials observed within the site building are listed in Table 3. 6 FINDINGS
A limited HBMS was performed at the site building to evaluate if potential hazards associated with the building materials, paint or other suspect LCMs and/or miscellaneous hazardous building materials may exist.
6.1 Asbestos-Containing Materials
Based upon the analytical results associated with these sampling activities, the following ACMs were identified:
• Approximately 20 linear feet of gray roof penetration mastic (samples ASB-21 and ASB22) collected from north and east roof penetrations were both reported to contain 3% chrysotile asbestos.
6.2 Lead-Containing Materials
Thirteen paint chip samples were collected for analysis of lead content. Five of the paint chip samples were reported with lead concentrations at >0.5% by weight (or >5,000 mg/kg). Blue paint located on an east wall of the northwest work shop area (sample PB-01) was reported with a lead concentration of 2.6% by weight (or 26,000 mg/kg). Cream paint on the ceiling of the northwest workshop area (sample PB-05) was reported with a lead concentration of 5.3% by weight (or 53,000 mg/kg). Green paint as observed as part of on an exterior wall mural (sample PB-11) was reported with a lead concentration of 5.8% by weight (or 58,000 mg.kg). Blue paint observed as part of an exterior wall mural (sample PB-12) was reported with a lead concentration of 4.4% by weight (or 44,000 mg.kg). White paint observed as part of an exterior wall mural (sample PB-13) was reported with a lead concentration of 4.3% by weight (or 43,000 mg.kg). These paint samples are considered LBP.
Six of the 13 paint samples were reported with lead concentrations at less than their associated lead detection limits. The other two paint samples (PB-02 and PB-03) were reported with lead Ninyo & Moore | Union City Youth Bike Shop, 33629 Mission Boulevard, Union City, California | 404370004 | May 27, 2025 5 concentrations of 0.0092% by weight (or 92 mg/kg) and 0.034% by weight (or 340 mg/kg), respectively. These paint samples are considered LCP.
Occupational Health and Safety Administration (OSHA) regulations apply whenever materials with any detectable amounts of lead are disturbed. A copy of the CDPH form 8552 “Lead Hazard Evaluation Report” for the project area is included in Appendix D.
6.3 Miscellaneous Hazardous Building Materials
Miscellaneous hazardous building materials observed within the site building included fluorescent lights and associated ballasts and an air conditioning/heating unit. 7 RECOMMENDATIONS
Since ACMs, LCMs and miscellaneous hazardous building materials have been reported within the site building the following recommendations and precautions are provided:
• The identified ACMs within the site building should not be disturbed. Any ACMs in damaged condition should be promptly repaired or abated. Prior to renovation or demolition work that would disturb the ACMs, a licensed asbestos abatement removal contractor should remove the ACMs in compliance with the most recent applicable federal, state, and local laws, regulations, standards, and/or codes governing abatement, transport, and disposal of ACMs. The removal work scope and requirements should be included in a work plan/specification developed by a California Certified Asbestos Consultant (CAC). It is also recommended that all abatement activities should be conducted under the observation of a CAC. While Ninyo & Moore provided an estimate of the quantity of ACMs within the site building (Table 1), it is the abatement contractor’s responsibility to assess the actual ACM quantities present. • The identified LCMs reported within the site building should not be disturbed. Any LCMs found in a damaged or non-intact condition should be abated and/or stabilized. Prior to renovation or demolition work that would disturb the identified LCMs a licensed lead abatement removal contractor should stabilize and/or remove the identified LCMs in compliance with the most recent applicable federal, state, and local laws, regulations, standards, and/or codes governing abatement, transport, and disposal of LCMs. All lead waste must be properly characterized prior to disposal to determine waste classification, packaging, transportation, and disposal requirements. While Ninyo & Moore provided an estimate of the quantity of LCMs present within the site building (Table 2), it is the abatement contractor’s responsibility to assess the actual LCM quantities present.
Ninyo & Moore | Union City Youth Bike Shop, 33629 Mission Boulevard, Union City, California | 404370004 | May 27, 2025 6 • Prior to demolition or renovation activities, potential mercury-containing thermostats/switches, PCB-containing items (light ballasts, transformers, etc.), fluorescent light tubes, exit signs, air conditioning units, and FreonTM-containing refrigeration systems should be removed and properly recycled or disposed of by a licensed contractor according to applicable federal, state, and local laws/regulations. Light fixtures should be visually inspected, prior to disposal, to determine if they contain PCBs (checked for “No PCBs” or “PCB free” stickers). While Ninyo & Moore provided an estimate of the quantity of miscellaneous hazardous building materials present within the site structure (Table 3), it is the abatement contractor’s responsibility to confirm the quantities of items present.
• There is a possibility that additional suspect ACMs, LCMs or other miscellaneous hazardous building materials may be discovered during building renovation and/or demolition activities. Therefore, Ninyo & Moore recommends that, should additional suspect materials not sampled or assessed in this report be uncovered during demolition/renovation activities, (a) samples of suspect materials should be collected for laboratory analysis and activities that may impact the materials should cease until laboratory analytical results are reviewed or (b) the materials should be assumed to be hazardous and handled as such.
8 LIMITATIONS
Ninyo & Moore's opinions and recommendations regarding environmental conditions, as presented in this report, are based on limited sampling and chemical analysis. Further assessment of potential adverse environmental impacts may be accomplished by conducting a more comprehensive assessment. The samples collected and used for testing, and the observations made, are believed to be representative of the areas evaluated. However, if additional suspect hazardous building materials are encountered during renovation/demolition activities, these materials should be sampled by qualified personnel, and analyzed for content prior to further disturbance. In addition, please note that quantities of identified hazardous building materials are approximate. It is the contractor’s responsibility to assess the actual quantities of hazardous building materials present.
The environmental services described in this report have been conducted in general accordance with current regulatory guidelines and the standard of care exercised by environmental consultants performing similar work in the project area.
