Approval of Nebraska's Air Quality Implementation Plan, Operating Permits Program, and 112(l) Program; Revision to Nebraska Administrative Code; Withdrawal of Direct Final Rule

Due to adverse comments, the Environmental Protection Agency (EPA) is withdrawing the direct final rule for "Approval of Nebraska's Air Quality Implementation Plan, Operating Permits Program, and 112(l) Program; Revision to Nebraska Administrative Code," published in the Federal Register on October 5, 2017. Nebraska's SIP revision revised two chapters, "Definitions" and "Operating Permit Modifications; Reopening for Cause". Specifically, these revisions incorporated 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 were amended to be consistent with the Federal operating permit program requirements, and the definition of "solid waste" was revised by the state. However, because the state's definition is inconsistent with the Federal definition, EPA was not approving the definition into the SIP. Finally, the state extended the process of "off-permit changes" to Class 1 operating permits. Additional grammatical and editorial changes were made in this revision.
