| E9-20047 | Approval and Promulgation of Air Quality Implementation Plans; Maryland; Clean Air Interstate Rule | Proposed Rule | EPA is proposing to approve State Implementation Plan (SIP) revisions submitted by the State of Maryland on October 24, 2007 and June 30, 2008, except for the 2009 nitrogen oxides (NO<INF>X</INF>) ozone season and NO<INF>X</INF> annual allocations, the 2009 set-aside allocations and the Compliance Supplement Pool (CSP) allocations. These revisions address the requirements of EPA's Clean Air Interstate Rule (CAIR). Although the District of Columbia (DC) Circuit found CAIR to be flawed, the rule was remanded without vacatur and thus remains in place. Thus, EPA is continuing to approve CAIR provisions into SIPs as appropriate. CAIR, as promulgated, requires States to reduce emissions of sulfur dioxide (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 full SIP revisions that EPA is proposing to approve, Maryland will meet CAIR requirements by participating in these cap-and- trade programs. EPA is proposing to approve the full SIP revisions, as interpreted and clarified herein, as fully implementing the CAIR requirements for Maryland, except for the 2009 NO<INF>X</INF> ozone season and NO<INF>X</INF> annual allocations, the 2009 set-aside allocations and the CSP allocations. | 2009-08-20 | 2009 | 8 | https://www.federalregister.gov/documents/2009/08/20/E9-20047/approval-and-promulgation-of-air-quality-implementation-plans-maryland-clean-air-interstate-rule | https://www.govinfo.gov/content/pkg/FR-2009-08-20/pdf/E9-20047.pdf | Environmental Protection Agency | 145 | EPA is proposing to approve State Implementation Plan (SIP) revisions submitted by the State of Maryland on October 24, 2007 and June 30, 2008, except for the 2009 nitrogen oxides (NO<INF>X</INF>) ozone season and NO<INF>X</INF> annual allocations, the... |
