On March 26, OMB Watch, along with the Powder River Basin Resource Council, Wyoming Outdoor Council, and Earthworks, filed a petition requesting that the Wyoming Oil and Gas Conservation Commission (WOGCC) disclose information about chemicals used in hydraulic fracturing, also known as fracking. The case, now before Wyoming's Seventh District Court, could set the tone for future cases in the more than 10 states with chemical disclosure rules similar to Wyoming's.
