In 2006, the California Integrated Waste Management Board (now CalRecycle) established a high-level state and local illegal dumping enforcement task force to assess the extent of the illegal dumping problem and develop recommendations to CalRecycle to enhance the effectiveness of local and state responses to the problem. Topics and recommendations addressed include, but are not limited to, legislative, outreach, public education, enforcement, coordination (including regional coordination summits), human resource, budgetary and financial proposals. The task force (now the technical advisory committee) also developed and conducted a survey of local jurisdictions to assess the extent and cost of the illegal dumping problem and identified content for this Illegal Dumping Resources Toolbox. To address the long-term problems associated with illegal dumping, the task force was later changed to a technical advisory committee.


The advisory committee provides ongoing expertise for CalRecycle, is comprised of voluntary members, and is not required to function under the statutory requirements of a legislative or department-created committee.

2020 Work Plan

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

Subcommittees have been created to execute the four Work Plan components: Strategy, Outreach, Standards, and Enforcement. The Work Plan includes elements and expectations of each subcommittee. Subcommittee findings will be vetted through the IDTAC and highlighted in the Toolbox as appropriate.

Task Force and Technical Advisory Committee History

The 21-member task force was selected, and the first meeting was held on March 29, 2006 in Sacramento. At this meeting an initial list of discussion items was presented to the task force. The second meeting was held May 24, 2006, at which time a revised list of discussion items was presented titled "Issues under Consideration for Inclusion in Final Report." The new document represents a work in progress based on review of the previous list of discussion items.

In the ensuing four months, the identified issues were discussed at local task force meetings and regional coordination meetings. The third task force meeting was held on September 14, 2006. At that meeting, task force members agreed to include 24 recommendations in the report to the CIWMB (now CalRecycle), and they prioritized the top six recommendations. They also reviewed the initial results of the fiscal impact surveys and agreed to accepting additional data from counties and cities.

The CIWMB Strategic Policy Development Committee discussed the final report at its March 6, 2007, meeting during Agenda Item 10. The board members were receptive to the idea of the board taking a leadership role in providing technical assistance, coordination, and outreach to local and State agencies. The board also asked that a small group of staff convene to lay out a work plan for implementing the report and return to the board with the proposed work plan within a few months.

The board directed the task force to reconvene at the August 7, 2007 meeting of the Strategic Policy Development Committee, with recognition approval at the August 14, 2007 board meeting. The board asked the task force to meet to review the implementation plan staff developed for the Illegal Dumping Program. The task force reconvened on October 4, 2007. The plan was presented as part of the Strategic Directive Report at the December 4, 2007 Policy Development Committee meeting, and the full board on December 11, 2007. The board directed staff to move forward on developing best management practices for illegal dumping abatement and enforcement and identify what components should be included in an illegal dumping outreach and public awareness program.

Board staff and task force members completed outlines of the Illegal Dumping Toolbox, Rules of Evidence, and a Refuse Hauler Service Provider Program and presented the concepts at the October 22, 2008, meeting of the task force. Board staff and task force members provided five state-wide training sessions on the development of effective local illegal dumping programs in spring 2009. Board staff completed the Illegal Dumping Toolbox and it went online in the fall of 2009.

Following a discussion on waste mattresses at the December 14, 2011 technical advisory committee meeting, CalRecycle staff initiated a limited survey on the problem and cost of handling illegally dumped mattresses and the cost and method of their disposal. In addition, the technical advisory committee members discussed the solid waste disposal issues associated with unregulated waste haulers. The members formed a discussion group that was charged with developing alternative to governing unregulated haulers. Report-backs on these issues were presented at the May 23, 2012 technical advisory committee meeting.

The November 27, 2012 technical advisory committee meeting included a presentation on used mattresses from the sleep products industry, the mattress recycling industry, and the mattress remanufacturing industry. Senate Bill 254, Used Mattresses Recovery and Recycling Program, was also discussed at the meeting, and it was decided that development of local guidelines on the used mattress issue would not be pursued.

Based on requests for discussion and guidance received from members of the technical advisory committee, the June 30, 2013 committee meeting provided a discussion on homeless encampments. Topics included wastes and issues related to homeless encampments, the residents of encampments, and regulation/enforcement issues related to homeless encampments. The technical advisory committee agreed to initiate development of a guidance document that would be added to the Illegal Dumping Toolbox.  CalRecycle staff completed a draft homeless encampment document that was reviewed at the November 13, 2013 technical advisory committee meeting, and approved at the March 13, 2014 technical advisory committee meeting. The homeless encampment reference guide web page was published in September 2013.
