6.R. - Page 2 of 9 In 2015, the Regional Water Board reissued the MRP, a National Pollutant Discharge Elimination System (NPDES) permit that regulates discharges of stormwater runoff. The MRP includes provisions that implement the requirements to reduce discharges of PCBs in stormwater runoff to the Bay. These include Provision C.12.f., which requires Permittees to develop new programs to manage PCBs—containing building materials during demolition. Remodeling, partial building, wood framed structure, and single- family residence demolition projects are exempt. The MRP requires that these new programs are adopted and begin implementation by July 1, 2019. ANALYSIS Redwood City along with other jurisdictions subject to the MRP is required by the MRP to reduce PCBs discharges in stormwater runoff. This regulation targets priority -building materials that may contain relatively high levels of PCBs, especially in buildings constructed between 1950 and 1980. The priority building materials are caulking, thermal/fiberglass insulation, adhesive/mastic, and rubber window gaskets. It is recommended that these priority building materials are regulated during demolition to prevent the materials and associated PCBs from potentially being released to the environment and transported to the Bay by stormwater runoff. This regulation requires an assessment process for PCBs in building materials that is analogous in some ways to the process currently implemented for asbestos—containing materials. It requires that Redwood City notify demolition permit applicants about the new requirements to conduct a PCBs in Priority Building Materials Screening Assessment. An application will be required for all building demolition permits. Information provided in the application will indicate whether the demolition is being done on an applicable structure. Applicants who request demolition of applicable structures will need to do additional testing on the priority building materials and provide certification of the testing done. An application package will be made available for all applicants that describes how an applicable structure is determined and the process for testing and certifying the results. The City will then be required to provide the documentation with the annual MRP report. There was extensive outreach to stakeholders including demolition contractors and building groups during the creation of the guidance and tools via the Bay Area Stormwater Management Agencies Association (BASMAA). One representative from the demolition contractor industry was on the technical advisory group for the effort, but no one from real estate or building industry participated, though they were invited to do so. The demolition contractor representative was also invited to stakeholder community meetings (two were held in 2017/2018 and one was focused mainly on industry outreach), and two meetings were held as training opportunities which industry representatives were invited to in fall 2018. There was also a follow-up outreach webinar designed for industry representatives in March 2019 to discuss issues around demolition permit processes and applicable structures/materials under the proposed programs. FISCAL IMPACT There is no fiscal impact to the City as a result of this action. Staff time will be charged to the applicants for review of the demolition permits.
