Approval and Promulgation of Implementation Plans and Approval of 112(l) Authority; Lincoln-Lancaster County Health Department (LLCHD) and City of Omaha (Nebraska)

This final action approves the State Implementation Plan (SIP) submitted by the state of Nebraska on behalf of the two local air pollution control agencies. The state has an approved program (published in the Federal Register on January 4, 1995), and the local agencies have adopted the same regulatory framework in order to issue Federally enforceable Class II permits. This request is sound, since the local agencies will administer independent Title V programs and should also offer relevant sources the alternative Class II permits. Furthermore, all applicable sources in the state (and in the local agencies' jurisdiction) are already subject to the requirements of the Class II operating permit program. Therefore, the only practical change created by this SIP revision for sources in Omaha or Lincoln-Lancaster County is that these Class II permits will be issued by the local agencies instead of the state. This revision includes the creation of a Class II operating permit program and adopts the state's Part D (nonattainment) new source review rule changes, SO<INF>2 rule corrections, and provisions for compliance and enforcement information. These revisions are identical to those adopted by the state and have been approved by EPA in the January 4, 1995 Federal Register. The EPA's rationale for that approval is contained in the cited Federal Register document and in the ``Technical Support Document (TSD) for a Revision to the Nebraska SIP and Request for Approval under Section 112(l)'' dated August 12, 1994, which is also part of the rationale for this approval. The creation of a Class II operating permit program enables the local agencies, like the state, to have a Federally enforceable program for sources not covered by the requirements for Title V sources under the Clean Air Act Amendments of 1990 and part 70 of the Code of Federal Regulations (CFR), and for sources not subject to Title V because they are able to obtain a Class II permit.
