Site Mitigation Program

Last modified: 1/30/2015 9:46 AM

Treat the earth well: it was not given to you by your parents, it was loaned to you by your children. We do not inherit the earth from our ancestors, we borrow it from our children."

- An Ancient American Indian Proverb


Our Mission

The Site Mitigation Program addresses the protection of the County of Santa Clara's water resources, specifically groundwater basins, through the prevention and cleanup of adverse environmental factors, preservation and improvement of beneficial environmental factors that affect our community's health and safety and the minimization of the economic costs to the general public and business community of our County.


Local Oversight Program (LOP)

Since July 1, 2004 the Department of Environmental Health (DEH) has served as the oversight agency for investigations and clean-up of petroleum releases from underground storage tanks through implementation of the Local Oversight Program (LOP) contract with the State Water Resources Control Board (SWRCB). The program services all cities and unincorporated areas within Santa Clara County. Prior to July 1, 2004 the Santa Clara Valley Water District served as the oversight agency.

LOP documents (electronic case files) received prior to April 1, 2014 are posted on the LUSTOP website. Documents relating to site cases and other related reference information are available for online viewing by clicking on the link provided in our Quick Links on the right side of our page. Contact information is available through the links to the right or at the bottom of our page.

NOTE: Effective April 1, 2014, the DEH will no longer be updating the LUSTOP website (electronic case files for fuel leak cases) and will not require a separate submittal to LUSTOP for reports. We will continue to maintain the historical documentation for each case file. All correspondence and reports issued after April 1, 2014 can be found on Geotracker at (


Voluntary Cleanup Program (VCP)

The VCP oversees the cleanup of properties contaminated by hazardous materials not from underground petroleum storage tanks. The California Health & Safety Code Sections 101480 through 101490 provides that a Responsible Party (RP) for a contaminated site may request our oversight of a site investigation and any remediation necessary to mitigate the site. Oversight activities include review of Phase I and Phase II investigations, required site assessment and remediation work plans, review of required sampling operations, analysis of sampling data, and establishment of site cleanup criteria. VCP caseworkers can provide speedy review times, generally within a few weeks.

The VCP requires Responsible Parties (RPs) to enter into a Remedial Action Agreement (RAA). This RAA must be in place prior to our oversight on any project. A sample RAA is available below for reference. Do not complete this form and submit to our office. We will generate the RAA after all required notifications have been made.

Please refer to the VCP brochure available below for download to understand the process of entering into our VCP program. You will also find a VCP Application, which needs to be completed and submitted to the email address below.  Do not send money with your application.

We suggest that you contact us directly to discuss your project prior to submitting an application to expedite the process. A link below will provide you with phone numbers of our staff.
