SB 4 Resources

SB 4 regulates well stimulation treatments in California, including hydraulic fracturing and acid well stimulation. The law creates a permitting system, builds in water testing and monitoring components for surface and groundwater near the treatment site, and it places obligations on state agencies to study any environmental effects of well stimulation treatment. SB 4 also obligates the Division of Oil, Gas & Geothermal Resources ("DOGGR") to finalize and implement permanent regulations, which are due by January 1, 2015, and gives DOGGR emergency regulatory authority to issue regulations for the 2014 interim period. Stoel attorneys Michael Mills and Tom Henry have prepared a primer to aid operators in their efforts to comply with SB 4 and its new permitting scheme.
