| Abstract: This guidance, issued by EPA's Office of Air & Radiation, was released for States to use in implementing the Clean Air Act requirements for ground-level ozone and particulate matter during the transition time between implementation of the old and new air quality standards. This guidance is intended to ensure that States maintain the momentum of existing control programs for ozone and particulate matter during the time when they are preparing their plans to implement the new standards. This guidance applies to all areas now subject to EPA's 1-hour standard and the pre-existing particulate matter standards and provides additional flexibility to States to achieve these standards. PLEASE NOTE: EPA will implement the concepts discussed in this guidance through subsequent guidance and rulemaking actions, as appropriate. Such rulemaking actions include approving or disapproving State implementation plan submittals. In a related matter, EPA is releasing a list of all of the counties for which the 1-hour ozone standard has been revoked. The new 8-hour standard remains in effect for these counties. EPA will formally "designate" areas as attainment or nonattainment for the 8-hour standard in the year 2000. (19 pages) |
