| E9-26090 | Approval and Promulgation of Air Quality Implementation Plans; Maryland; Clean Air Interstate Rule | Rule | EPA is approving State Implementation Plan (SIP) revisions submitted by the State of Maryland, with the exception of its 2009 nitrogen oxides (NO<INF>X</INF>) ozone season and NO<INF>X</INF> annual allocations, its 2009 set-aside allocations and the Compliance Supplement Pool (CSP) allocations. The revisions establish budget trading programs for nitrogen oxides (NO<INF>X</INF>) annual, NO<INF>X</INF> ozone season, and sulfur dioxides (SO<INF>2</INF>) annual emissions to address the requirements of EPA's Clean Air Interstate Rule (CAIR). Maryland will meet its CAIR requirements by participating in the EPA-administered regional cap-and-trade program for NO<INF>X</INF> annual, NO<INF>X</INF> ozone season, and SO<INF>2</INF> annual emissions. EPA is determining that the SIP revisions fully implement the CAIR requirements for Maryland. Although the DC Circuit found CAIR to be flawed, the rule was remanded without vacatur and thus remains in place. Thus, EPA is continuing to take action on CAIR SIPs as appropriate. CAIR, as promulgated, requires States to reduce emissions of SO<INF>2</INF> and NO<INF>X</INF> that significantly contribute to, or interfere with maintenance of, the national ambient air quality standards (NAAQS) for fine particulates and/or ozone in any downwind state. CAIR establishes budgets for SO<INF>2</INF> and NO<INF>X</INF> for States that contribute significantly to nonattainment in downwind States and requires the significantly contributing States to submit SIP revisions that implement these budgets. States have the flexibility to choose which control measures to adopt to achieve the budgets, including participation in EPA-administered cap-and-trade programs addressing SO<INF>2</INF>, NO<INF>X</INF> annual, and NO<INF>X</INF> ozone season emissions. In the SIP revisions that EPA is approving, Maryland will meet CAIR requirements by participating in these cap-and- trade programs. EPA is approving the SIP revisions, with the exceptions noted, as fully implementing the CAIR requirements for Maryland. Consequently, this action will also cause the CAIR Federal Implementation Plans (CAIR FIPs) concerning SO<INF>2</INF>, NO<INF>X</INF> annual, and NO<INF>X</INF> ozone season emissions by Maryland sources to be automatically withdrawn. | 2009-10-30 | 2009 | 10 | https://www.federalregister.gov/documents/2009/10/30/E9-26090/approval-and-promulgation-of-air-quality-implementation-plans-maryland-clean-air-interstate-rule | https://www.govinfo.gov/content/pkg/FR-2009-10-30/pdf/E9-26090.pdf | Environmental Protection Agency | 145 | EPA is approving State Implementation Plan (SIP) revisions submitted by the State of Maryland, with the exception of its 2009 nitrogen oxides (NO<INF>X</INF>) ozone season and NO<INF>X</INF> annual allocations, its 2009 set-aside allocations and the... |
