Approval and Promulgation of Air Quality Implementation Plans Maine; Redesignation to Attainment and PMINF10 Contingency Measures for Presque Isle

Résumé

EPA is proposing full approval of Maine's request to redesignate the Presque Isle area to attainment for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM 10), along a maintenance demonstration and contingency plans which outline Maine's control strategy for maintenance of the PM 10 national ambient air quality standards (NAAQS). Additionally, EPA is proposing full approval of a State Implementation Plan (SIP) revision submitted by the State of Maine to satisfy federal requirements for contingency measures for the Presque Isle initial nonattainment area. In the Final Rules Section of this Federal Register, EPA is approving this redesignation request and SIP revision as a direct final rule without prior proposal because the Agency views this as a noncontroversial revision and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule.
