| E9-25052 | Approval and Promulgation of Air Quality Implementation Plans; South Carolina; Clean Air Interstate Rule | Proposed Rule | EPA is proposing to approve a revision to the South Carolina State Implementation Plan (SIP) submitted by the State of South Carolina through the South Carolina Department of Health and Environmental Control on December 4, 2008. This revision addresses the requirements of EPA's Clean Air Interstate Rule (CAIR). Although the District of Columbia Circuit Court 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 nitrogen oxides (NO<INF>X</INF>) that significantly contribute to, or interfere with maintenance of, the national ambient air quality standards 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 revision that EPA is proposing to approve, South Carolina will meet CAIR requirements by participating in these cap-and-trade programs. EPA is proposing to approve the full SIP revision, as interpreted and clarified herein, as fully implementing the CAIR requirements for South Carolina. 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 ozone season emissions by South Carolina sources to be automatically withdrawn. This action is being taken pursuant to section 110 of the Clean Air Act. | 2009-10-16 | 2009 | 10 | https://www.federalregister.gov/documents/2009/10/16/E9-25052/approval-and-promulgation-of-air-quality-implementation-plans-south-carolina-clean-air-interstate | https://www.govinfo.gov/content/pkg/FR-2009-10-16/pdf/E9-25052.pdf | Environmental Protection Agency | 145 | EPA is proposing to approve a revision to the South Carolina State Implementation Plan (SIP) submitted by the State of South Carolina through the South Carolina Department of Health and Environmental Control on December 4, 2008.
