About ESI

In September 2004, the State Water Resources Control Board (SWRCB) adopted regulations that require Electronic Submittal of Information (ESI) for groundwater cleanup programs. For several years, parties responsible for cleanup of leaks from underground storage tanks (USTs) have been required to submit groundwater analytical data, surveyed locations of monitor wells, and other data to the Geotracker database over the Internet. As of January 1, 2005, electronic submittal of information has been be required by all groundwater cleanup programs including UST, Non-tank Site Cleanup (SCP), Military Sites, and Land Disposal Sites. These regulations also added new Data Dictionaries (the format for electronic data submittals) to Title 27, CCR, in coordination with existing Cal/EPA Unified Program Data Dictionaries.

As of January 1, 2005, electronic submittal of a complete copy of all necessary reports has been required in Geotracker (in PDF format). The electronic copy is intended to replace the need for a paper copy and is expected to be relied upon for all public information requests, regulatory review, and compliance/enforcement activities.

The Geotracker system is capable of accepting this electronic information and currently has information submitted by responsible parties for over 20,000 LUST, SCP and Military Sites statewide. The process of claiming a site, formatting and uploading data, and other technical information can be found under the “ESI Overview” section.

Benefits of Electronic Reporting

The implementation of electronic reporting has provided benefits for both the SWRCB and the public.

Electronic reporting provides decision makers with accurate, up to date, accessible, and complete statewide information concerning cleanup sites where there has been a chemical release.

Enhances the capabilities of the SWRCB, Regional Water Quality Control Boards (RWQCB), and local regulatory agencies in monitoring and assessing the contaminant threat to drinking water wells.

Facilitates public access to information: instead of having to physically travel to a government building to review a paper copy of the case file, concerned individuals can review and analyze information over the Internet.
