The proposed revisions to the NSR program would govern when advance approvals of certain changes would be appropriate. EPA and states have been testing many of the flexible permittingapproaches for more than a decade. Based on the agency's evaluation of pilot projects, EPA expects that these proposed changes will promote significant environmental and economic benefits, while reducing administrative workload for both permitting authorities and facilities.
EPA will accept comment on this proposed rule for 60 days after it is published in the Federal Register. More about the proposal: http://epa.gov/nsr/actions.html#aug07
