Approval of Missouri's Air Quality Implementation Plans, Operating Permits Program, and 112(l) Plan; Construction Permits Required

Environmental Protection Agency (EPA) is taking direct final action to approve revisions to Missouri's State Implementation Plan (SIP), Operating Permits Program, and 112(l) Plan. The April 6, 2016, request from Missouri revises fees for permitting services provided by the air quality program, including construction permit applications and operating permit applications. Missouri also removed the basic operating permit requirement in their ``Operating Permits'' rule for incinerators with emissions less than the de minimis levels. While EPA has never approved the basic operating permit program into Missouri's SIP or Missouri's Operating Permits Program, one statement on incinerators in the approved SIP and Operating Permits Program is removed by the submission. This statement applied the ``Operating Permits'' rule to all incinerators within the State. Any permittees with incinerators already required to have either Intermediate State Operating Permits or part 70 Operating Permits will still have the same permitting requirements. This revision does not exempt any incinerators from appropriate permitting. Likewise, any future permittees with incinerators under the former version of the SIP and Operating Permits Program would have required either an Intermediate State Operating Permit or a part 70 Operating Permit will still have the same permitting requirement under the revised SIP and Operating Permits Program. Finally the submission from Missouri makes non-substantive style changes.
