Operator Requirements for Water Reporting

The Division of Oil, Gas, and Geothermal Resources (Division) has developed an interim process for collecting detailed water use information in response to Senate Bill 1281 amendments to Public Resources Code (PRC) Section 3227. The interim process is a Microsoft Excel report form which will be pre-populated with oil and gas operator well information. This form will be referred to as the quarterly water report. The pre-populated quarterly water report will be emailed to individual operators at the end of each quarter. Operators who do not have a valid email address on file with the Division will have to make an appointment with their local Division District office to file their report. District office information can be found at the Division Contacts link on the right side of this page. Operators who want to establish an email address with the Division, or change an existing address, can call the Division’s Electronic Data Processing (EDP) unit at (916) 323-0426 or (916) 323-0427. They can also email the change to SB1281Reporting@conservation.ca.gov.

Existing law gives oil and gas operators one month after the quarter to file the quarterly water report. Operators are to email their completed reports to SB1281Reporting@conservation.ca.gov. Operators who must file their report at the local District office will, on the day of their appointment, utilize the Division’s public use computer to access, complete, and file their report.

As mentioned above, the process described is an interim solution for meeting the requirements of Senate Bill 1281. After a period of adjustment, the Division will begin meeting with oil and gas operators, and other stakeholders to develop a permanent online access and reporting system. It’s anticipated this process will take one to two years to complete.
