Approval and Promulgation of Air Quality Implementation Plans; Virginia; Revision of Flow Control Date in Nitrogen Oxides Budget Trading Program

Riepilogo

EPA proposes to convert a conditional approval in the Virginia State Implementation Plan (SIP) to a full approval. As required by the conditional approval, Virginia has submitted a SIP revision pertaining to the change in flow control date in the allowance banking provisions of its NO x Budget Trading Program. In the Final Rules section of this Federal Register, EPA is approving the Commonwealth'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 rationale for the conversion action is set forth in the direct final rule. 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.
