New Polychlorinated Biphenyls (PCB's) Management Policy

Notice to Property Owners, Developers, and Contractors:

New PCBs Screening Requirements Prior to Demolition

The City of Cupertino is required by the Regional Water Board via the Municipal Regional Permit to reduce discharges of polychlorinated biphenyls (PCBs) in stormwater runoff. Applicable commercial, public, institutional, and industrial structures constructed or remodeled between January 1, 1950, and January 1, 1981, may have PCBs in materials prioritized for screening such as caulk, insulation, mastic, and window gaskets. During demolition, PCBs can be released as dust and end up in our water and air.

Applicants proposing to demolish applicable structures built or remodeled between 1950 and 1981 must conduct a PCBs screening assessment before a demolition permit will be issued. Single-family residential and wood frame structures are exempt. The screening assessment guides applicants to:

1) Determine whether the structure is likely to have building materials containing PCBs;
2) Determine whether PCBs are present at a concentration equal to or greater than 50 parts per million (ppm) in prioritized building materials of interest, which include caulk, insulation, mastic, and window gaskets. (To find a contractor to do testing, contact the Association of Environmental Contractors (AEC) at aec-ca.org or the Association of Northern California
Environmental Consultants (ANCEC) at ancec-ncal.com).
3) Follow applicable federal and state laws if PCBs exist in priority building materials. This may include reporting to USEPA, the San Francisco Bay Regional Water Quality Control Board (RWQCB), and the California Department of Toxic Substances Control (DTSC). These agencies
may require additional sampling and abatement of PCBs.
