Area Source MACT Guidance On August 5, 2010 Ohio EPA provided guidance for implementing Area Source MACT’s – Ohio EPA has not accepted delegation of the recent area source MACT standards – Adding a permit term that states an area source MACT may apply – U.S. EPA will be responsible for enforcement of the rule

11. Area Source MACT Guidance – De Minimis determinations are done without considering the area source MACT’s – Area Source MACT does not affect permit exemption determinations in OAC rule 3745-31-03 – DO/LAA are not responsible to perform inspections for area source MACT’s – Initial notifications should be sent to U.S. EPA with Ohio EPA Central Office and DO/LAA copied
