On June 21, EPA extended the comment period by 30 days for its proposed utility MACT, but EPA Administrator Lisa Jackson said that extending the comment period “will not impact” plans to issue a final rule to reduce emissions of mercury and other air toxics from power plants in November 2011. Former House Energy and Commerce Chairman John Dingell (D-MI.) and 27 House Democrats called on Jackson earlier this month to provide 60 more days for the comment period, citing the complexity of the rule requiring coal-fired power plants and other power generators to use maximum achievable control technology (MACT) to curb emissions. EPA Deputy Administrator Robert Perciasepe, implied that EPA will likely resist calls for delaying the regulations, noting that there will be three years to fully comply and that states can provide industry an additional year after that. On June 21st, more than one hundred House Democrats including Reps. Lois Capps (CA), Edward Markey (MA), and Bobby Rush (IL) signed on to a letter urging Jackson to move forward on the rule.
