Well Stimulation Treatment Permitting Phase-OutPre-Rulemaking
The Geologic Energy Management Division has publicly released pre-rulemaking draft regulations for the purpose of receiving public input on the development of a rule that ends permitting for well stimulation treatments in 2024. Comments received during the current comment period will be reviewed and considered in developing proposed regulations for formal rulemaking. Written submissions may be provided by July 4, 2021, by email at CalGEMRegulations@conservation.ca.gov.
SB 463 Chemical Inventory & Root Cause AnalysisPre-Rulemaking (Underground Gas Storage Facilities)
On September 28, 2021, CalGEM released a pre-rulemaking discussion draft of regulations for the purpose of receiving public input. The proposed regulations are intended to meet requirements of Senate Bill 463 (Stern, 2019) for operators to submit a chemical inventory of materials that could be emitted from a gas storage well in the event of a reportable leak. In addition, these regulations identify specific mitigation activities, including cathodic protection, well-specific well control plans, and the reporting of off-normal occurrences, that are responsive to the independent root cause analysis of the Aliso Canyon well leak in 2015.
Gas Pipeline Mapping System
(for active gas pipelines in sensitive areas)
On May 17, 2019, DOC's Geologic Energy Management Division (CalGEM) released pre-rulemaking discussion drafts of regulations and specifications for the purpose of receiving public input on the development of digital submission guidelines for mapping of active gas pipelines in sensitive areas. DOC staff is reviewing public feedback on the drafts.
From February 16 - March 30, 2018, CalGEM accepted public comment on a pre-rulemaking draft (discussion draft) of proposed Statewide Geothermal Regulations, including two proposed forms. DOC staff is reviewing public feedback on the draft and forms.
