2017-21109: Approval and Promulgation of Air Quality Implementation Plans; Maryland; 2011 Base Year Inventory for the 2008 8-Hour Ozone National Ambient Air Quality Standard for the Baltimore, Maryland Nonattainment Area

Summary

The Environmental Protection Agency (EPA) proposes to approve, as a state implementation plan (SIP) revision, the 2011 base year inventory for the Baltimore, Maryland moderate nonattainment area for the 2008 8-hour ozone national ambient air quality standard (NAAQS) submitted by the State of Maryland through the Maryland Department of the Environment (MDE). In the Final Rules section of this issue of the 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. 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 or is also available electronically within the Docket for this rulemaking action. 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.
