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

摘要

EPA is fully approving 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). EPA is also approving 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. This action is being taken under the Clean Air Act.
