Approval of Nebraska Air Quality Implementation Plans, Operating Permits Program, and 112(l) Program; Revision to Nebraska Administrative Code

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the State Implementation Plan (SIP), Operating Permits Program, and 112(l) Program submitted on July 14, 2014, by the State of Nebraska. This action amends the SIP to revise two chapters, "Definitions" and "Operating Permit Modifications; Reopening for Cause". Specifically, these revisions incorporate by reference the list of organic compounds exempt from the definition of volatile organic compound (VOC) found in the Code of Federal Regulations; notification requirements for the operating permit program are being amended to be consistent with the Federal operating permit program requirements; the definition of "solid waste" is being revised by the state, however, because the state's definition is inconsistent with the Federal definition, EPA is not approving this definition into the SIP. Finally, the state is extending the process of "off-permit changes" to Class I operating permits. Additional grammatical and editorial changes are being made in this revision. Approval of these revisions will not impact air quality, ensures consistency between the state and Federally-approved rules, and ensures Federal enforceability of the state's rules.
