Colorado oil-gas regulators take rules dispute to high court

DENVER (AP) — The Colorado attorney general asked the state Supreme Court Thursday to settle a dispute over how much weight public health and the environment should have in regulating the booming oil and gas industry.

Attorney General Cynthia Coffman asked the justices to review a decision by Colorado's second-highest court, the Court of Appeals, that said health and environmental protection should have a higher priority than regulators currently give it.

That could significantly change Colorado's long-running battle over the proliferation of hydraulic fracturing wells near fast-growing urban areas, giving opponents more power to argue for safety measures, including restrictions on where wells can be drilled.

Hydraulic fracturing — or fracking — uses a high-pressure mix of water, sand and chemicals to loosen underground formations and release oil and gas. Some say the chemicals are dangerous but the industry says the technique is safe.

The Colorado Oil and Gas Conservation Commission, which regulates the industry, has traditionally said state law requires it to balance public safety and the environment against responsible oil and gas production.

But the Court of Appeals ruled in March that regulators had misinterpreted the law, and that they are required to ensure public and environmental protections, not balance them against other considerations.

Coffman's appeal said the lower court had essentially rewritten state law and contradicted previous Supreme Court decisions.

The Supreme Court did not immediately indicate whether it would hear the appeal.

The case stems from a 2013 request by six young people who wanted regulators to require energy companies to show they would not harm human health or the environment before drilling.
