Report: EPA climate rules for power plants likely delayed

Rewriting the proposal would significantly delay any action, and might allow the agency to set a separate standard for coal-fired power plants, which are roughly twice as polluting as those fueled by natural gas.

While the move could bolster the administration’s legal justification for regulating power plants’ carbon emissions, any retreat on the rules would be a blow to environmental groups and their supporters, who constituted a crucial voting block for President Obama and other Democrats in last year’s elections.

EPA did not respond to an inquiry from The Hill Friday afternoon.

The potential changes and delays for the rules for new plants come as green groups are strongly pressing the agency to impose restrictions on existing coal plants, a major source of greenhouse gas emissions.
