6/15/99 - Section 126 Petitions

On June 11, 1999, EPA temporarily stayed the effectiveness of its final action on the Section 126 petitions submitted by eight northeastern states. The stay is effective until November 30, 1999. It separates the Section 126 petitions from the recent court decisions so that EPA can proceed with regional reductions of ozone under the 1-hour national ambient air quality standards. On June 14, EPA sent letters to Governors of several northeastern states notifying them of this action.

Also on June 14, EPA issued a final rule extending the timeframe for consideration and action on the Section 126 petitions submitted by Delaware, New Jersey and Maryland. The six month extension allows EPA adequate time to develop its' proposed action and provide time for public comment.

On June 15, EPA proposed to amend the April 30, 1999 rule on Section 126 petitions to remove the link between the NOx SIP call deadlines and the final action granting the Section 126 petitions from the eight northeastern states. In this notice, EPA is proposing to indefinitely stay the determinations of technical merit based on the 8-hour ozone standards, pending further developments in the litigation of the national ambient air quality standards for ozone.

See EPA's Fact Sheet summary for all three rule actions signed on June 11, 14, and 15.

5/25/99 - On May 25, 1999, a 3-judge panel of the US Court of Appeals for the DC Circuit issued an order partially staying the implementation of EPA's plan to reduce the state-to-state transport of smog ("NOx SIP call"). This is not a ruling on the merits of the plan, but a delay to allow all parties to argue their case before the court. EPA is evaluating the order, and, in the fall, will join a number of states in arguing before the court the need to move forward with these important health protections.

5/14/99 - Published in the Federal Register May 14, 1999: "Technical Amendment to the Finding of Significant Contribution and Rulemaking for Certain States for Purposes of Reducing Regional Transport of Ozone. "This action revises the SIP call's Statewide NOx emissions budgets.
