Final 2018 Memorandum of Agreement Between the State Water Resources Control Board and the Department of Conservation, Division of Oil, Gas, and Geothermal Resources
The State Water Resources Control Board (State Water Board) and the California Geologic Energy Management Division (CalGEM) have signed the Revised Memorandum of Agreement between the State Water Board and CalGEM regarding underground injection control, discharges to land and other program issues (2018 Revised MOA).
Aquifer Exemption Proposals
The California Geologic Energy Management Division ("CalGEM"), with concurrence of the State Water Resources Control Board ("State Water Board"), is considering proposals to expand current aquifer exemption designations statewide. Subject to approval by the US Environmental Protection Agency ("US EPA"), the proposed aquifer exemptions would allow the State, in compliance with the federal Safe Drinking Water Act, to approve Class II injection into the identified area, either for enhanced oil recovery or for injection disposal of fluids associated with oil and gas production.
Public hearings for each proposal will be held in communities near the aquifer exemption proposals. For updated information on upcoming public hearings and aquifer exemption proposals, please visit https://www.conservation.ca.gov/calgem/Pages/Aquifer_Exemptions.aspx
Performance Measures for Model Criteria: New information is now available
Information on performance measures for the evaluation of the Model Criteria for Groundwater Monitoring in Areas of Oil and Gas Well Stimulation is available here.
Senate Bill 83 - Underground Injection Control and Produced Water Pond Report
Senate Bill (SB) 83 Section 45 (statutes of 2015) requires that the State Water Board submit a status report on the regulation of oil field produced water ponds by January 30, 2016, and every six months thereafter. These reports include the total number of ponds in each region, the number of permitted and unpermitted ponds, enforcement actions, and the status of permitting the unpermitted ponds.
SB 83 also requires CalGEM and the State Water Board to semi-annually report to the relevant committees of the Legislature on the status of the Department of Conservation’s underground injection control (UIC) program. The most recent UIC report can be found in the “Legislative Reports " section under the Reports, Publications tab on the CalGEM website titled "Underground Injection Control Report" https://www.conservation.ca.gov/calgem/pubs_stats/Pages/legislative_reports.aspx
Details on the Water Boards status on regulating activities for Produced Water Ponds are available here.
