| 2011-27620 | Approval of Air Quality Implementation Plans; California; South Coast; Attainment Plan for 1997 PM2.5 Standards | Rule | EPA is approving in part and disapproving in part state implementation plan (SIP) revisions submitted by California to provide for attainment of the 1997 fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards in the Los Angeles-South Coast area (South Coast). These SIP revisions are the South Coast 2007 Air Quality Management Plan (South Coast 2007 AQMP) (revised 2011) and South Coast-related provisions of the 2007 State Strategy (revised 2009 and 2011). EPA is approving the emissions inventory; reasonably available control measures/reasonably available control technology demonstration; the reasonable further progress and attainment demonstrations and associated air quality modeling; and the transportation conformity motor vehicle emissions budgets. EPA is also granting California's request to extend the attainment deadline for the South Coast to April 5, 2015 and approving commitments to measures and reductions by the South Coast Air Quality Management District and the California Air Resources Board. Finally, we are disapproving the SIP's contingency measures and issuing a protective finding under 40 CFR 93.120(a)(3), and we are rejecting the assignment of 10 tons per day (tpd) of nitrogen oxide (NO<INF>X</INF>) reductions to the federal government. | 2011-11-09 | 2011 | 11 | https://www.federalregister.gov/documents/2011/11/09/2011-27620/approval-of-air-quality-implementation-plans-california-south-coast-attainment-plan-for-1997-pm25 | https://www.govinfo.gov/content/pkg/FR-2011-11-09/pdf/2011-27620.pdf | Environmental Protection Agency | 145 | EPA is approving in part and disapproving in part state implementation plan (SIP) revisions submitted by California to provide for attainment of the 1997 fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards in the Los... |
