Gov. Bruce Rauner's office says the Illinois Environmental Protection Agency is looking into potential ways to comply with the federal Clean Power Plan, which is set to slash carbon emissions from existing U.S. power plants.
The state's environmental agency "is still reviewing the rule and determining potential compliance pathways," said Rauner spokeswoman Catherine Kelly, the Associated Press reported on Friday.
States are given flexibility to meet carbon standards under the U.S. Environmental Protection Agency's regulations.
When the EPA's finalized regulations were released in August, Rauner's office responded with a one-sentence statement saying that it was reviewing the Clean Power Plan. The August statement didn't say whether Illinois would challenge the Clean Power Plan.
Twenty-four states, not including Illinois, filed lawsuits last week against the Clean Power Plan.
