Wyoming promulgates new rules (2010)

Wyoming Oil and Gas Conservation Commission (WOGCC) Rules and Regulations, August 2010. On August 16, 2010, by his signature, Governor Dave Freudenthal approved new rules, which cover a variety of drilling practices including hydraulic fracturing. Operators must now provide the names of chemical additives and the Chemical Abstracts Service number, compound type, and compound concentrations or rates proposed to be mixed and injected as part of the hydraulic fracturing process.


Operators must also provide the actual names of chemical additives and Chemical Abstracts Service number, compound type, and concentrations or rates post well stimulation treatment.  The rules also allow state regulators to hold confidential “trade secret” information if operators can prove it meets the statutory requirements. The disclosure rules went into effect September 15, 2010. Rules can be accessed at the WOGCC Web site: http://wogcc.state.wy.us
