Notice of Intent to Revise Nebraska’s Regional Haze State Implementation Plan
Extension of Comment Period
Notice is hereby given to the public that the Department is extending the public comment period for Nebraska’s Regional Haze State Implementation Plan (SIP). The proposed SIP revision addresses the requirements in section 169A of the Clean Air Act (CAA) and the Regional Haze rule, Title 40 Code of Federal Regulations (CFR) 51.308. The revised plan addresses the second implementation period of the Regional Haze rule (2018-2028) and is the second of six ten-year plans required by the CAA; it evaluates Nebraska’s progress in implementing the Regional Haze rule and identifies emission reduction measures, which are necessary for the second implementation period, to make reasonable progress in reaching the Environmental Protection Agency’s (EPA) goal of eliminating man made visibility impairment at federally designated Class I areas by 2064. The revised SIP will be submitted to the U.S. Environmental Protection Agency (EPA) for review and approval following the public notice and comment period.
NDEE consulted with Federal Land Managers (FLMs) from the National Park Service (NPS), U.S. Forest Service, and U.S. Fish and Wildlife Service, and provided to them a copy of its draft Regional Haze SIP on November 17, 2022, for review. FLM feedback and recommendations were provided to NDEE on January 31, 2023, and are summarized as follows:
- NPS supported Nebraska’s selection of two facilities selected for four-factor analysis and encouraged the state to evaluate four additional facilities; Nebraska responded with a detailed explanation of its source selection process and rationale.
- NPS conducted its own analyses of the six facilities to identify cost-effective controls, and encouraged Nebraska to reconsider both sulfur dioxide (SO2) and nitrogen dioxide (NOx) emission measures to require cost-effective controls to reduce the most haze-causing emissions; Nebraska responded with a detailed explanation of its cost analyses and factors considered when determining the necessity and reasonableness of controls.
- NPS had concerns about Nebraska’s rationale for rejecting potential control measures and its consideration of affordability and visibility benefits; Nebraska responded with a detailed explanation of its cost analyses and factors considered when determining the necessity and reasonableness of controls.
- U.S. Forest Service concurred, in general, with the findings and recommendations submitted by the NPS; it also recommended that Nebraska use the EPA Control Cost Manual in its cost analysis, that the state reconsider SO2 and NOx controls, and noted that visibility was not a factor for consideration in this process and the use of the Uniform Rate of Progress (URP) glideslope was not supported by the Regional Haze Rule; Nebraska responded with a detailed explanation of its cost analysis and determination of the necessity and reasonableness of controls.
Documents from this consultation process, including FLM comments/analyses and Nebraska’s responses, are contained in Appendix D of the SIP.
The proposed SIP revision and supporting documents are available for inspection* by the public through 4:00 PM November 8, 2023 at the office of the NDEE, 245 Fallbrook Boulevard, STE 100, Lincoln, Nebraska, and electronically at http://dee.ne.gov.

Box 98922, Lincoln, Nebraska 68509-8922.
