For Operators - Underground Injection Control

​​​​​Owners and operators of UIC wells and facilities in California are required to abide by certain laws and regulations to obtain a permit to operate injection wells. On April 1, 2019, new mandates took effect.

The Department of Conservation's Geologic Energy Management Division (CalGEM, formerly DOGGR) hosted an informational workshop regarding implementation of the new regulations. This UIC Workshop Presentation highlights those requirements and enhancements of prior regulations. 

UIC Program Requirements

*Any injection project requires a review and concurrence from the California Water Boards. CalGEM signed an updated MOA ​(PDF)with the water boards on how UIC projects are documented and processed. Injection projects under review​ (PDF).

**Compliance with the California Environmental Quality Act (CEQA) must be documented if your proposed project requires a discretionary permit or approval from CalGEM.
