6.R. - Page 8 of 9 building is an applicable structure .4 It is anticipated that many projects will not involve the demolition of applicable structures. Demolition permit applicants for projects that don't involve applicable structures will only need to address the initial screening questions and certify the answers. 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 (BASMAA 2018). Per the Applicant Package, for certain types of buildings built between 1950 and 1980, the Applicant must conduct further assessment to determine whether or not PCBs are present at concentrations >_ 50 ppm.5 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 having the samples analyzed 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. 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 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 USEPA before building demolition. Even in circumstances where advance notification to or approval from USEPA is not required before the demolition activity, the disposal of PCBs waste is regulated under Toxic Substances Control Act (TSCA). Additionally, the disposal of PCBs waste is subject to California Code of Regulations (CCR) Title 22 Section 66262. Additional information is provided in the Applicant Package. The focus of this regulation is on PCBs runoff prevention to protect water quality. The regulation does not: • Ask for municipal oversight or enforcement of human health protection standards. • Ask for municipal oversight of PCBs abatement or remediation of materials or lands contaminated by PCBs. 'Applicable structures are defined as structures built or remodeled from January 1, 1950 to December 1, 1980, with remodeling, partial building, wood framed structure, and single-family residence demolition projects being exempt. 5 MRP Provision C. 12.f states: "Permittees shall develop and implement or cause to be developed and implemented an effective protocol for managing materials with PCBs concentrations of 50 ppm or greater in applicable structures at the time such structures undergo demolition so that PCBs do not enter MS4."
