Docusign Envelope ID: 3713C5F7-2612-47EB-8930-D61 C6FA121 BC Dublin Municipal Code Chapter 7.29 MANAGEMENT OF PCBs DURING BUILDING DEMOLITION PROJECTS A. Determine whether the building proposed for demolition is high priority for PCBs - containing materials based on the structure age, use, and construction (i.e., whether the building is an applicable structure); and if so, B. Demonstrate the presence or absence and concentration of PCBs in priority building materials through existing information or representative sampling and chemical analysis of the priority building materials in the buildings. -and, C. Document that priority building materials with PCBs concentrations equal to or greater than 50 ppm in demolished applicable structures are disposed of appropriately and according to state and federal regulations; and D. Document that enhanced construction site best management practices during the demolition process to minimize migration of PCBs into the municipal separate storm sewer system shall be implemented by the applicant. Enhanced construction site best management practices include the following: 1. Inspect demolition projects during the dry season (May 1 through September 30 of a given year); 2. Conduct additional wet season inspections, as necessary (beyond the once per month minimum required by the MRP); 3. Perform street sweeping daily throughout demolition and construction activities; and 4. Cover demolition debris with an impermeable liner until debris is removed from the project site. Applicants shall follow the directions provided in the PCBs in priority building materials screening assessment applicant package (applicant package), which includes an overview of the process, applicant instructions, a process flow chart, a screening assessment form, and the Protocol for Assessing Priority PCBs -Containing Materials before Building Demolition. Per the applicant package, for certain types of buildings built within a specified date range, the applicant must conduct further assessment to determine whether or not PCBs are present at concentrations greater than or equal to fifty (50) parts -per million. This determination is made via existing data on specific product formulations (if available), or, more likely, via conducting representative sampling of the priority building materials and analyzing the samples for PCBs at a certified analytical laboratory. Any representative sampling and analysis must be conducted in accordance with the Protocol for Assessing Priority PCBs -Containing Materials before Building Demolition. The applicant package provides additional details. 7.29.060. Agency notification, abatement, and disposal for identified PCBs. The Dublin Municipal Code is current through Ordinance 2-24, passed June 25, 2024. Docusign Envelope ID: 3713C5F7-2612-47EB-8930-D61C6FA121 BC Dublin Municipal Code Chapter 7.29 MANAGEMENT OF PCBs DURING BUILDING DEMOLITION PROJECTS When the PCBs in priority building materials screening assessment identifies one or more priority building materials with PCBs, the applicant must comply with all related applicable federal and state laws, including potential notification of the appropriate regulatory agencies, including the EPA, the Regional Water Board, and/or the DTSC. Agency contacts are provided in the applicant package. Additional sampling for and abatement of PCBs may be required. Depending on the approach for sampling and removing building materials containing PCBs, the applicant may need to notify or seek advance approval from the EPA before building demolition. Even in circumstances where advance notification to or approval from the EPA is not required before the demolition activity, the disposal of PCBs waste is regulated under Toxic Substances Control Act. Additionally, the disposal of PCBs waste is subject to California Code of Regulations (CCR) Title 22 Section 66262. Official documentation shall be provided to the city of Dublin demonstrating proper disposal of PCBs containing building materials. 7.29.070. Compliance with California and federal PCBs laws and regulations. Applicants must comply with all federal and California laws and regulations, including but not limited to health, safety, and environmental laws and regulations, that relate to management and cleanup of any and all PCBs, including but not limited to PCBs in priority building materials, other PCBs -contaminated materials, PCBs -contaminated liquids, and PCBs waste. 7.29.080.

Owner and project information, including location, year building was built, description of building construction type, and anticipated demolition date. 2. Determination of whether the building proposed for demolition is high priority for PCBs - containing building materials based on the structure age, use, and construction. 3.

If PCBs concentrations are determined via representative sampling and analysis, include a contractor's report documenting the assessment which includes the completed quality assurance/quality control checklist from the Protocol for Assessing Priority PCBs - Containing Materials before Building Demolition and the analytical laboratory reports. 4. For each priority building material present with a PCBs concentration equal to or greater than fifty (50) parts -per million, the approximate amount (linear feet or square feet) of that material in the building. B. Applicant's certification of the accuracy of the information submitted. The appropriate authority may specify a format or guidance for the submission of the information.
