The Environmental Protection Agency announced last week that will need two additional months to finalize air quality standards for ozone, issuing a final rule in September 2014 instead of July. The agency set the ozone national ambient air quality standards at 0.075 parts per million in 2008, but the Obama administration announced that it would reconsider the standards. In September, the administration dropped the reconsideration because it did not want to increase regulatory burdens.
