The White House Office of Information and Regulatory Affairs (OIRA) is reviewing under Executive Order 12866 a revised air pollutant rule. The rule is the National Ambient Air Quality Standard for ozone, a.k.a. smog. Over the past several months, Reg•Watch has been tracking the growing support for tightening this critical air pollution standard. Scientists and medical professionals have been lining up to voice their support, but EPA has been cautious in expressing its opinion on more protective smog regulation. Considering the environmental track record of the current administration, experts are skeptical. Frank O'Donnell at Clean Air Watch is framing the revision of the standard as a science vs. politics showdown. Read his breakdown here. OIRA should complete its review within 90 days. Reg•Watch hopes science prevails and the proposed rule calls for tighter standards. If not, who will be to blame: EPA, the White House or both?
