Approval and Promulgation of Air Quality Implementation Plans; Delaware; 2011 Base Year Inventories for the 2008 8-Hour Ozone National Ambient Air Quality Standard for New Castle and Sussex Counties

The Environmental Protection Agency (EPA) proposes to approve the 2011 base year inventories for the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS) for New Castle and Sussex Counties, submitted by the State of Delaware as a revision to the Delaware State Implementation Plan (SIP). In the Final Rules section of this Federal Register, EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. The rationale for the approval is set forth in the direct final rule. A more detailed description of the state submittal and EPA's evaluation is included in a Technical Support Document (TSD) prepared in support of this rulemaking action. A copy of the TSD is available, upon request, from the EPA Regional Office listed in the ADDRESSES section of this document. If no adverse comments are received in response to this action, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time.
