EPA is required by Section 109(d) the Clean Air Act to review the adequacy of each National Ambient Air Quality Standard (“NAAQS”) every five years to determine if new scientific evidence justifies a change to the standard.  The current primary[i] NAAQS for nitrogen dioxide (“NO2”) is 53 ppb annual mean and 100 ppb NO2 as

With that in mind, and after careful consideration, I have requested that Administrator Jackson withdraw the draft Ozone National Ambient Air Quality Standards at this time. Work is already underway to update a 2006 review of the science that will result in the reconsideration of the ozone standard in 2013.” 1

The request was delivered to EPA Administrator Lisa Jackson via a letter from Cass Sunstein, Director of the Office of Management and Budget. The letter stated that the decision was based on the President’s Executive Order 13563, which emphasizes that “Our regulatory system must protect public health, welfare, safety, and our environment while promoting economic growth, innovation, competitiveness, and job creation.” The letter from OMB indicated that EPA was already in the process of reviewing the ozone standard again based upon the most recent science and is required to complete that review by 2013. It urged EPA to complete that process. However, OMB indicated that the President requested that EPA “reconsider” its proposed rule in light of the directives of the Executive Order, in particular, to “promote predictability and reduce uncertainty.” The OMB letter flatly stated that President Obama did not support EPA’s proposed rule and that regulatory agencies should take action consistent with the President’s priorities. 2
