Eight states blame upwind sources. Agency to revisit emissions targets.
The U.S. Environmental Protection Agency's Sept. 24 rule for 22 eastern states to file plans to reduce nitrogen oxide emissions would ostensibly reduce transport of ground-level ozone, or smog, in so-called "nonattainment areas." But eight of these affected states have filed petitions arguing that NOx emissions blowing in from nearby jurisdictions must be controlled before they can comply.
So far, in preliminary statements, the EPA has indicated that at least some of these petitions have merit.
