Environmental and landowner groups are celebrating after the Wyoming Supreme Court found a lower court had ruled in error regarding disclosure of the chemicals used in hydraulic fracturing or fracking.

The Wyoming Supreme Court heard a case Wednesday challenging the state’s process for exempting fracking chemicals from public disclosure. Wyoming was the first state in the nation to adopt a disclosure law, but it included what some say is a massive loophole: companies can petition for what’s called a trade secret exemption. They’ve done that more than a hundred times since the law went into effect in 2010.

Several environmental groups went to district court today in Casper to argue that the Wyoming Oil and Gas Conservation Commission must disclose information about chemicals being used in hydraulic fracturing around the state. Wyoming was the first state to require companies to disclose such information, yet since that law went into effect, the Oil and Gas Commission has granted almost all secrecy requests from companies claiming that some of the chemicals are proprietary information.
