The EPA is taking direct final action to grant full approval for the Guam operating permit program and an associated State Implementation Plan (SIP) revision submitted by the Territory of Guam (Guam). These submittals correct deficiencies identified in EPA's direct final interim approval rulemaking of January 9, 2003 (68 FR 1162). Final approval of Guam's alternate permit program and associated SIP revision will allow sources to be permitted under an approved alternate permit program. This alternate program fulfills all of the requirements that Guam adopt and submit an alternate local permitting program as part of a conditional exemption under section 325 of the Clean Air Act (Act) from Title V of the Act.
