Mass. DEP's Cash says revised carbon plan formula probable in final rule

How should U.S. EPA address stakeholder concerns raised during this week's public and congressional hearings on its Clean Power Plan? During today's OnPoint, David Cash, commissioner at the Massachusetts Department of Environmental Protection, explains why he believes grid reliability, coal plant efficiency and state flexibility concerns will continue to be sticking points for the proposal as the agency accepts comments on the rule. Cash also discusses the likelihood EPA will establish a revised formula for assigning emissions reduction targets to the states.
