Brownfields Funding

Targeted Site Investigation (TSI) Program

The TSI Program has been suspended for 2020 – Currently soliciting input for TSI+ Program

Since 2004, the TSI Program has been part of DTSC’s CERCLA 128(a) State and Trial Response Program Grant, funded by the United States Environmental Protection Agency (U.S. EPA). DTSC provided environmental services to local governments, school districts, and non-profit organizations to facilitate the return of brownfields to safe and productive uses. The program focused on properties with a clear need for redevelopment, strong redevelopment potential, real or perceived contamination, and municipal/community support for redevelopment. Assessment, investigation, and cleanup planning have been provided to over 100 projects, in 68 cities, and 30 counties, throughout the State of California. Although the TSI Program has been suspended for 2020, here are the links to the 2019 Application and Guidelines, for reference.

Why has the TSI Program been suspended?

Unfortunately, due to uncertainty caused by COVID-19, the TSI Program has been suspended for 2020. However, this time will be used to innovate and transform the TSI Program into the TSI+ Program.

What will we be doing during the hiatus?

Building on the success of the TSI Program, DTSC envisions an enhanced TSI+ Program to support local governments, school districts, tribes, and non-profit organizations as they return brownfields to safe and productive uses. We will use the hiatus to examine, experiment and innovate, and hopefully return with a program that better facilitates development of brownfields and supports Californian communities.

How can you help?

If you have suggestions for an innovation for the TSI+ Program, please forward your suggestions, with “TSI+ Innovation” in the subject line of your email, to TSI Program Coordinator,

U.S. Environmental Protection Agency (EPA) Brownfields Grant Support

The U.S. EPA offers a variety of grant and loan programs and technical assistance to help communities assess and clean up brownfields and prepare them for redevelopment. Information on U.S. EPA brownfields grants is currently available at U.S. EPA’s Brownfields Grants page. The application deadline is December 3, 2019. In order to develop a complete proposal package, the U.S. EPA requires a letter of acknowledgement from a state agency. Learn how to obtain a Letter of Acknowledgment from DTSC.

DTSC helps U.S. EPA grant applicants and recipients access federal brownfields funding by determining eligibility of petroleum-contaminated brownfields sites, under CERCLA section 101(39)(D). This is not a regulatory determination. A petroleum eligibility determination by DTSC, under CERCLA section 101(39)(D), for the purpose of brownfields funding does not release any party from obligations under any federal or state law or regulation, or under common law, and does not impact or limit EPA or state enforcement authorities against any party. Refer to the following guidelines and application to request this grant support from DTSC.
