US EPA Delays Rollout of New Clean Power Rules

On January 7, the EPA announced that it is delaying release of proposed power plant rules. The rules are intended to lower the power sector’s greenhouse gas emissions 30 percent by 2030. EPA states the delay is meant to give states time to develop compliance plans.

The rules for new power plants were originally slated to be released this week, but their release is now postponed to align with the later release of rules governing existing and modified plants. EPA explained that finalizing the rules for all three types of plants concurrently will allow it to consider overlapping issues in a coordinated fashion. Finalization of the rules is set for mid-summer.

One consequence of the delay is that Congress cannot attempt to override the rules under the Congressional Review Act until later this year. Another outcome of releasing all three rules together is that this strategy could make it harder to bring effective legal challenges against rules; EPA could claim that the new rules constitute a single action, and thus must be challenged in a single brief. EPA, however, denies that legal strategy is motivating the delay.

It is unclear whether there could be further delays down the road, but EPA has at least one important reason for getting the rules finalized on schedule: it would be one of the Obama Administration’s last actions.
