EPA Signs Final Rule Partially Rejecting Wyoming's Regional Haze Plan

January 17, 2014 —

On Friday, January 10, 2013 EPA Regional Administrator for Region 8, Shaun McGrath, signed a final decision partially rejecting Wyoming’s regional haze state implementation plan (“SIP”). EPA’s final 714 page decision partially rejects Wyoming’s SIP due to deficiencies in Wyoming’s plan and imposes a Federal plan to cover the portions of the rejected state plan.  In its proposed rule released this summer for public comment, EPA proposed rejecting Wyoming’s determination of best available retrofit technology (“BART”) improvements to address nitrogen oxide (NOx) emissions at several coal-fired power plants: Laramie River Station, Wyodak, Naughton, Jim Bridger and Dave Johnson. EPA’s final action approved Wyoming’s plan for Jim Bridger and Naughton.  However, EPA disapproved Wyoming’s plan, and imposed a Federal plan for the Dave Johnson, Wyodak and Laramie River plants.  

Please look for CLERR Deputy Director Temple Stoellinger’s article on Wyoming’s regional haze plan in the upcoming February issue of the Wyoming Lawyer

An advance copy of the final rule is available on the EPA Region 8 website, it has not yet been published in the federal register.
