A letter supported by 91 House members urged EPA’s Administrator Lisa Jackson to combine its reconsideration of the national ambient air quality standards for ozone with its regular five-year review of the standards. The EPA will soon complete a final rule to revise the ozone standards set in 2008, even though it has already begun the scheduled five-year review, which is to be completed in 2013 and could lead to further changes in the standards. The letter was signed by a bipartisan group of legislators.
