Wyoming Must Step Up to Curb Haze Pollution, EPA Says

Agency calls for Tougher Emission Controls, Proposes Partial Disapproval of Wyoming’s Haze Plan

Wyoming – Today marks the conclusion of EPA’s public comment period on its proposal to partially disapprove Wyoming’s regional haze state implementation plan (SIP), meant to show progress towards reducing haze pollution that blurs iconic views in national parks and wilderness areas from Yellowstone National Park to Bridger Wilderness Area. Community members had 30 days to weigh in ahead of EPA’s final decision slated to be issued in November, and supported EPA in its partial disapproval of the plan to enforce stricter controls on emissions. 

EPA’s proposal to partially disapprove the plan came after years of delay and litigation tactics from Wyoming’s worst polluting power plants to avoid regulation, enabled by a previous SIP that required no new emissions reductions. The current plan, submitted by Wyoming’s Air Quality Division to EPA on February 18, 2022, should have met the requirements of the Regional Haze Rule, a program established under the Clean Air Act. But it was a do-nothing, flawed plan that incorrectly concluded that no new reductions in pollution were warranted for any of the state’s industrial sources. 

Wyoming has found itself here before. In 2022, EPA proposed to disapprove an earlier haze  SIP submitted by the state in May of 2020 for evading implementation of pollution control technology. That’s why advocates are now calling on EPA to enact a Federal Implementation Plan (FIP) that includes strong and significant emission-reducing measures for the state’s top haze polluters that include the Jim Bridger, Naughton, Dave Johnston, and Wyodak coal plants – primarily operated by one of the largest utilities in the nation, PacifiCorp. If EPA finalizes its current decision to disapprove the SIP, it has two years to implement a federal plan.

Regional haze pollution in Wyoming muddies scenic views and can travel hundreds of miles from its original source, through communities and neighborhoods, causing serious health impacts like heart and respiratory disease. 

EPA has until November 22, 2024 to issue its final rule based on a consent decree signed by the U.S. District Court in response to legal action by Earthjustice, Environment Integrity Project, National Parks Conservation Association, and Sierra Club to include deadlines for EPA to take action on 32 states’ plans to reduce haze pollution in national parks and wilderness areas.

“Until EPA implements and enforces a Federal Implementation Plan, Wyoming will continue to submit flawed plans that allow our state’s worst polluters off the hook for emission controls,” said Rob Joyce, chapter director of the Sierra Club in Wyoming. “The longer that Wyoming is back at the drawing board, the more our air quality suffers, impacting the iconic and defining landscapes in treasured national parks. It’s urgent that EPA finalizes its proposal to disapprove the state’s flawed plan. In the meantime, it’s vital that community members weigh in, and call for the rejection and replacement of the state plan.”

“Visitors flock from around the world to Wyoming’s incredible national parks and expect clear, stunning scenic views and clean healthy air, yet haze pollution is a leading threat to these cherished experiences,” said Allison Michalski, Northern Rockies Connectivity Program Manager at the National Parks Conservation Association. “As economic engines, we must put these special places and the communities that rely on them first. For parks to thrive, it’s imperative and long overdue for Wyoming polluters to cut emissions causing hazy skies. EPA must hold Wyoming accountable to ensure clear skies and clean air in accordance with the tried-and-true Regional Haze Rule.”

“The people of Wyoming are thankful EPA is following the law and the science and forcing our state leaders to do more to clean up the pollution that mars our skies and hurts our health,” said Shannon Anderson, staff attorney at Powder River Basin Resource Council. “Wyomingites are calling on EPA to act swiftly to finally hold our coal-burning utilities accountable.” 

“National parks in Wyoming, from Devil's Tower to the majestic Tetons and Yellowstone are incredible sights to behold. As are other parks in nearby states like Wind Cave, Badlands, and Rocky Mountain, but not when they all are obscured with regional haze, resulting from coal plants and industrial facilities that lack modern pollution controls. I appreciate efforts by the EPA and my former National Park Service colleagues to ensure cleaner skies in these special places," said Sue Consolo-Murphy, a retired NPS employee and member of the Coalition to Preserve America's National Parks in Wapiti.

“People come to Wyoming for our crystal clear skies and to escape the smog they may live in. They won’t come to Yellowstone and Grand Teton if their views of the Grand are impeded by preventable haze, or if they are forced to breathe air filled with dust and particulates,” said Andrew Salter, Northern Rockies Regional Council Member for National Parks Conservation Association in Jackson. “I have made the choice, like many others, to make this region my home, in the clear air of the Grand Tetons – the backdrop that defines our community. WYDEQ proposed a weak, do-nothing regional haze plan that does not hold our state’s polluters accountable for their haze-causing pollution. Thanks to today's decision, EPA has taken a critical step towards achieving cleaner air in Wyoming."
