Colorado officials say they'll keep working on the state's plan to comply with the Obama administration's clean-power regulations despite a U.S. Supreme Court order delaying enforcement of the rules.
The Denver Post reported Wednesday the state Department of Public Health and Environment said Colorado needs to be ready in case the court eventually upholds all or part of the rules.
Kathy Green, a spokeswoman for Gov. John Hickenlooper, says the governor agrees that work on the plan should continue.
Hickenlooper, a Democrat, supports the clean-power rules. Republican Secretary of State Cynthia Coffman opposes them and joined other attorneys general in challenging them in court.
The Supreme Court on Tuesday barred enforcement of the rules while a lawsuit is pending before a federal appeals court in Washington.
