Two Final Rules Related to the 2008 Ozone NAAQS Published in the FR on May 21

On May 21 EPA published two final rules related to the 2008 ozone NAAQS in the Federal Register.

The first of the two rules:

  1. establishes the method for classifying ozone areas for the 2008 ozone NAAQS;
  2. establishes the attainment dates for areas in each classification;
  3. bumps up several areas in California to higher classifications; and
  4. revokes the 1997 ozone NAAQS for transportation conformity purposes.

Also, published today was the final rule that designates nonattainment areas for the 2008 ozone NAAQS.

Both final rules are effective on July 20, 2012.  The one-year conformity grace period starts on the effective of the designations.

Upcoming Webinar: An Introduction to EPA’s Greenhouse Gas Data Publication Tool

Thursday, March 1, 2012

2:00-3:30 PM EST

For the first time, comprehensive greenhouse gas (GHG) data reported directly from large facilities and suppliers across the country are now easily accessible to the public through EPA’s GHG Reporting Program. The 2010 GHG data includes public information from facilities in nine industry groups, including 29 source categories, that directly emit large quantities of GHGs, as well as suppliers of certain fossil fuels and industrial gases. This information can be used by state and local governments to identify nearby sources of GHGs, identify opportunities to improve efficiency and reduce emissions, or to inform policies and programs.

Staff from the GHG Reporting Program will take attendees through EPA’s online data publication tool that allows users to view and sort GHG data for calendar year 2010 from over 6,700 facilities in a variety of ways—including by facility, location, industrial sector, and the type of GHG emitted, and discuss ways in which state and local governments may be able to use this data.
