On February 23, in a settlement between the Environmental Protection Agency and the Independent Petroleum Association of America and the U.S. Oil and Gas Association filed in the U.S. Court of Appeals for the District of Columbia Circuit, the agency agreed to delete language on its website classifying injection wells that use diesel fuel as fracturing additives as “Class II wells” by the agency's Underground Injection Control Program. The suit alleged the online statement was a rulemaking without the public notice and comment required by the Safe Drinking Water Act, and the settlement stipulates that by March 15 the statement must be removed and replaced with a link to another website explaining the new process.
