Environmental Protection Agency Administrator Gina McCarthy on Monday said her agency would give states great flexibility in meeting new requirements for carbon emissions from power plants.
"EPA next June will propose new standards that will also provide significant flexibility to the states that will protect public health from carbon pollution from existing power plants," McCarthy said on Monday at the liberal Center for American Progress event.
"That will give opportunities to reduce power plant emissions."
McCarthy said the agency would be "really flexible on the implementation of these standards" with states.
And nine Northeastern and Mid-Atlantic states are asking for just that.
The Regional Greenhouse Gas Initiative called on the EPA on Monday to allow states to follow "flexible market-based carbon pollution programs."
