Solid Waste Disposal and Codisposal Site Cleanup Program

For over 30 years this program has facilitated the cleanups of legacy landfills and illegal disposal sites where:

  • The responsible party either cannot be identified or is unwilling or unable to pay for timely remediation, and
  • The cleanup is needed to protect public health and safety and/or the environment.

Funding in the form of grants and loans to eligible applicants to finance a wide range of remediation projects is available.

The program is also unique in that CalRecycle can provide direct cleanup assistance utilizing its own contractors in specific circumstances.
