Technical Advisory Committee

IDTAC logoBackground

The Illegal Dumping Technical Advisory Committee (IDTAC) provides ongoing expertise for CalRecycle and the state of California, is comprised of voluntary members, and is not required to function under the statutory requirements of a legislative or department-created committee. Started as a Task Force in 2006, the group evolved into today’s technical advisory committee and relative subcommittees given the long-term problems associated with illegal dumping. The IDTAC continues to assess the extent and cost of the illegal dumping, while sharing their findings, best practices, and strategies in the Illegal Dumping Resources Toolbox.

2020 Work Plan

The IDTAC identified the need to update its original work plan. The 2020 Work Plan entails developing fresh resources and tools for jurisdictions, communities, contractors, and others to assist in addressing current illegal dumping issues.

Focused Topics have included Homeless Encampments and Abandoned Vehicles.

Subcommittees

Subcommittees are comprised of IDTAC members and interested persons who assist the IDTAC on specific illegal dumping issues. Updates on subcommittee activities are provided during IDTAC meetings. To get involved in a subcommittee, please contact the subcommittee chair (see contact info in Committee Member table below) or IllegalDumping@calrecycle.ca.gov.
