This Unit provides assistance to regulatory agencies, land management agencies, and responsible parties to clean up and remediate old landfills and illegal disposal sites.  The programs and assistance provided are as follows:

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.
