The latest print edition of National Review offers this blurb:

President Obama postponed the drafting and implementation of a broad range of environmental regulations until after the 2012 election, and then until after the 2014 election. Now many of them are finally getting done, but on at least one of them, he should have waited forever. A new rule capping the levels of ozone, a component of smog, may be the most expensive single environmental regulation in history. And yet it’s being implemented after the amount of ozone in the atmosphere has decreased across the United States consistently over the past 30 years, reaching levels comfortably below what the EPA heretofore considered safe. The regulation could cost the American economy tens of billions of dollars per year in exchange for dubious environmental benefits. That kind of bargain, however, increasingly looks like the Obama EPA’s favorite blueprint.

Ill-considered ozone policies extend beyond the federal government’s misadventures. Roy Cordato recently discussed with Donna Martinez for Carolina Journal Radio/CarolinaJournal.tv dubious claims about the links between North Carolina’s ozone levels and the state’s so-called “Clean Smokestacks” law.
