This document is a deliverable of the BASMAA project: Managing PCBs−Containing Building Materials during Demolition: Guidance, Tools, Outreach and Training. BASMAA developed guidance, tools, and outreach and training materials to assist with San Francisco Bay Area municipal agencies’ (Permittees) efforts to address the requirements of Provision C.12.f. of the Bay Area Municipal Regional Stormwater Permit (referred to as the MRP). Provision C.12.f of the MRP requires Permittees to manage PCBs–containing building materials during demolition. Specifically, MRP Provision C.12.f.ii (3) requires that Permittees develop an assessment methodology and data collection program to quantify, in a technically sound manner, reductions in PCBs loads to municipal separate storm sewers systems (MS4s) through implementation of a new program for controlling PCBs during demolition of applicable structures.
This document summarizes existing information related to quantifying the potential reduction in PCBs loads to the MS4 that could be achieved through management of PCBs–containing building materials during demolition. It then provides a conceptual approach for developing the assessment methodology and data collection program using (1) existing data and information (e.g., from the literature, technical reports, and the MRP Fact Sheet), (2) information developed as part of other tasks for this project (e.g., the list of priority building materials), and (3) data anticipated to become available as a new program to manage PCBs–containing materials during building demolition goes into effect on July 1, 2019.
