The Environmental Protection Agency (EPA) proposes to approve the state implementation plan (SIP) revision submitted by the Maryland Department of the Environment (MDE) on behalf of the State of Maryland in response to EPA's February 3, 2017 Findings of Failure to Submit for various requirements relating to the 2008 8-hour ozone national ambient air quality standards (NAAQS). This SIP revision is specific to nonattainment new source review (NNSR) requirements. 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. A 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.
