"CHEYENNE, Wyo. -- A judge in Casper has sided with the state of Wyoming and ruled against environmentalists who sought to obtain lists of the ingredients that go into hydraulic fracturing fluids."
"Environmental groups had requested the ingredient lists from the Wyoming Oil and Gas Conservation Commission, arguing that the public needs to know what chemicals companies are putting underground.
They were denied on the grounds that the lists are trade secrets that may be withheld under Wyoming's open records law. Natrona County District Judge Catherine Wilking has upheld the denial, ruling that the state official who withheld the information acted reasonably."
