Site Mitigation & Restoration Program

We protect and maintain California’s land and places
by setting strict standards for land restoration and cleanup

Evaluation

The Quick Reference Guides focus on aspects on environmental investigation and evaluation, and include information on Preliminary Endangerment Assessments, Supplemental Site Investigations, and the Remedial Investigation process. California Land Reuse and Revitalization Act (CLRRA) related information is also presented, particularly since CLRRA has some unique aspects that are important to highlight. The DTSC Human and Ecological Risk Office (HERO) has provided abbreviated information on the human health risk assessment process, with links to more detailed information. DTSC partnered with the United States Environmental Protection Agency to outline information on managing polychlorinated biphenyl (PCB)-impacted properties in California. Additional Quick Reference Guides are under development, and the website will be updated on a routine basis. The Guides can be found in a panel to the right.

During this entire process, Public Participation Activities and Tribal Consulation is included, as needed. Possible End Points: 1) Based on site evaluation, projects may conclude without need for any further action; 2) Based on site evaluation, projects may conclude with the need for a Land Use Covenant, in which case a public notice process will be implemented through a Preliminary Endangerment Assessment, Report of Findings, or equivalent documents; and 3) Cleanups may either be conducted to unrestricted land use levels, or may require long term stewardships.
