Abstract: EPA is proposing action on petitions filed by eight northeastern States seeking to reduce ozone transport across State boundaries through reductions in NOx emissions. These petitions were filed under section 126 of the Clean Air Act, a legal mechanism which authorizes the States to petition EPA to address air pollution transported from upwind States. Each petition specifically requests that EPA make a finding that NOx emissions from certain stationary sources significantly contribute to ozone nonattainment problems in the petitioning State. The eight northeastern States that filed petitions are Connecticut, Maine, Massachusetts, New Hampshire, New York, Pennsylvania, Rhode Island, and Vermont. The States identified by the petitioning States as contributing to the significant transport of NOx include all of the 22 States and the District of Columbia that are subject to the NOx SIP call, plus other States as well. EPA is proposing to find that seven of the eight section 126 petitions have technical merit and that sources in 19 States and the District of Columbia significantly contribute to nonattainment in, or interfere with the ability of States to maintain clean air in, one or more of the petitioning States. For these sources, EPA is proposing the control requirements that would apply if the Agency makes a final finding. In selecting proposed requirements, EPA relied on the analysis for the NOx SIP Call. EPA is proposing to defer granting the approvable portions of the petitions until a later time since the Agency expects State submittals in response to the NOx SIP call, which are due in September 1999, will address the ozone transport identified by the petitioning state. This deferral would allow the affected States and the District of Columbia an opportunity to respond to the NOx SIP call before EPA would make any final finding.
