Approval and Promulgation of Air Quality Implementation Plans; District of Columbia; GSA Central and West Heating Plants

Riepilogo

EPA proposes to approve the State Implementation Plan (SIP) revision submitted by the District of Columbia for the purpose of limiting sulfur dioxide (SO 2 ) emissions at the General Services Administration's Central and West Heating Plants. In the Final Rules section of this Federal Register, EPA is approving the District'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 approval 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 on this action. Any parties interested in commenting on this action should do so at this time.
