John Siciliano of the Washington Examiner explains why the clock starts now for federal lawsuits challenging the Obama administration’s climate plan.

All rules will be published Friday, said EPA Aassistant Administrator Janet McCabe on a call with reporters. She said she is confident the rules are legally defensible and “that our application … conforms with legal precedent.”

A group of 16 states is prepared to sue the agency over the Clean Power Plan, which requires states to reduce emissions by one-third by 2030. The GOP will introduce a resolution of disapproval in attempt to repel the rule on the Hill.

McCabe said she is “confident we will make progress,” despite the opposition.

She also said the EPA will begin working with the states to help them “succeed” in meeting the targets of the rules, beginning a round of meetings with them in November and December on a renewable energy incentive program that seeks to boost solar and wind in the states ahead of Clean Power Plan implementation.

During an interview for the episode of Carolina Journal Radio that airs this weekend, N.C. Department of Environmental Quality Secretary Donald van der Vaart explains why he has concerns about the plan.
