By Notice of Public Hearing

A public hearing by the Environmental Protection Agency for Approval, Disapproval and Promulgation of Air Quality Implementation Plans; Partial Approval and Partial Disapproval of Air Quality Implementation Plans and Federal Implementation Plan; Utah; Revisions to Regional Haze State Implementation Plan; Federal Implementation Plan for Regional Haze; Proposed Rule this proposal is scheduled to be held on Tuesday, January 26, 2016, at the Salt Lake City Public Library, Main Library, from 1 p.m. until 5 p.m., and again from 6 p.m. until 8 p.m.
The Environmental Protection Agency (EPA) is proposing to take action pursuant to section 110 of the Clean Air Act on State Implementation Plan revisions submitted by the State of Utah on June 4, 2015, and October 20, 2015 to implement the regional haze program. The State’s SIP revisions establish an alternative to best available retrofit technology (BART) controls that would otherwise be required to control nitrogen oxides (NOX) at PacifiCorp’s Hunter and Huntington power plants.
The June 2015 SIP revision also includes BART determinations for particulate matter with an aerodynamic diameter of less than 10 micrometers at these power plants and provisions for making the NOX and PM 10 BART emission limits federally enforceable. The CAA requires states to prevent any future and remedy any existing man-made impairment of visibility in national parks and wilderness areas designated as Class I areas.
Air emissions from the four electric generating units at the two plants affected by this action cause or contribute to visibility impairment at nine Class I areas including Grand Canyon, Arches, Bryce Canyon and Zion National Parks. The EPA is issuing two co-proposals in order to fully evaluate the State’s submittals and the public’s input thereon. The EPA would work with the State on a revised State plan should a partial disapproval and FIP be finalized. Written comments must be received on or before March 14
