Clean air is still out of reach for Southwest national parks.

Two of Utah’s oldest, dirtiest coal-fired power plants — PacifiCorp’s Hunter and Huntington facilities — pollute the air in eight of the region’s national parks: Grand Canyon, Zion, Bryce Canyon, Capitol Reef, Arches, Canyonlands, Mesa Verde and Black Canyon of the Gunnison.

For years, the state of Utah has refused to make the necessary pollution reductions already in place at many other coal plants across the West. Although the state must comply with the Clean Air Act’s Regional Haze Rule, since 2008 it has continued to recycle a do-nothing plan that would allow the Hunter and Huntington plants to keep on spewing preventable haze pollution.

In response to the state’s persistently weak submissions, in June of 2016, the Environmental Protection Agency (EPA) finalized a regional haze plan for Utah that required the state to cut emissions from these coal plants by 76 percent — reducing haze-causing and health-harming nitrogen oxide pollution achievable through modern pollution controls.

In September 2017, the Trump-Pruitt EPA undercut the June 2016 regional haze plan, suspending the requirements that would protect Southwest national parks from coal pollution. In its place, EPA invited the state of Utah to propose yet another plan to replace the one providing these much-needed pollution reductions.

NPCA continues to advocate for the best option to clean the air: the June 2016 Utah haze plan to reduce pollution from the PacifiCorp coal plants. This plan is what is necessary to protect the Southwest’s most stunning national parks, their visitors and surrounding communities.
