Approval and Promulgation of Air Quality Implementation Plans; District of Columbia; Approval of Minor Clarifications to Municipal Regulations

Résumé

EPA is taking direct final action to approve revisions to the District of Columbia State Implementation Plan (SIP). The revisions include minor changes to clarify that the allowable emission rates for particulates and nitrogen oxides (NO X ) are expressed in pounds of pollutant per million BTUs (lbs/MMBTUs) of heat input in District of Columbia Municipal Regulations (DCMRs). 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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. Any parties interested in commenting on this action should do so at this time.
