Findings of Failure To Submit State Implementation Plan Revisions for Nonattainment Areas for the 2010 1-Hour Primary Sulfur Dioxide National Ambient Air Quality Standard

The Environmental Protection Agency (EPA) is taking final action to find that four States failed to submit State Implementation Plan (SIP) revisions required by the Clean Air Act (CAA) in a timely manner for certain nonattainment areas for the 2010 1-hour sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standard (NAAQS). The States that failed to submit the required SIP revisions are Arizona, Louisiana, New York, and Virginia. This action triggers certain CAA deadlines for the imposition of sanctions if a State does not submit a complete SIP addressing the outstanding requirements and for the EPA to promulgate a Federal Implementation Plan (FIP) if the EPA does not approve the State's SIP revision addressing the outstanding requirements.
