DENVER (Legal Newsline) – Colorado has joined a lawsuit challenging the Federal Bureau of Land Management’s new regulations on hydraulic fracturing, Colorado Attorney General Cynthia Coffman said on Friday.

 Colorado joins Wyoming and North Dakota in the legal action. The lawsuit asks the court to decide whether the Bureau of Land Management can legally impose its own regulations on hydraulic fracturing. The suit contends that the bureau doesn’t have that power because federal law delegates that responsibility to states to regulate such matters.
