In accordance with its prior proposed action, the U.S. Environmental Protection Agency (EPA) has finalized regulatory revisions that relax the ozone-season Reid vapor pressure (RVP) standard for six Florida counties. EPA previously imposed an ozone-season RVP standard of 9.0 psi statewide, except in Broward, Duval, Hillsborough, Miami-Dade, Palm Beach, and Pinellas Counties, which were subject to a more stringent ozone-season RVP standard of 7.8 psi due to having been previously designated as nonattainment areas for the 1979 1-hour ozone national ambient air quality standard (NAAQS). EPA’s revisions relax the ozone-season RVP standard for those six counties to 9.0 psi and follow its recent approval of revisions to Florida’s state implementation plan, which included, an identical relaxation of the ozone-season RVP standard.
The revisions become effective May 30, 2014.
