EPA is finalizing a revision to the long-term strategy portion of the Nevada federal implementation plan (FIP) for Class I visibility protection. This revision concerns emissions reduction requirements for the Mohave Generating Station (MGS) located in Clark County, Nevada. The new requirements are based on a consent decree entered into by the owners of MGS and the Grand Canyon Trust (GCT), the Sierra Club, and the National Parks and Conservation Association (NPCA). The emissions reductions resulting from compliance with the consent decree will address concerns raised by the Department of the Interior (DOI) regarding MGS's contribution to visibility impairment at the Grand Canyon National Park (GCNP) due to sulfur dioxide (SO<INF>2</INF>) emissions. In addition, incorporating the requirements of the consent decree into the long-term strategy of the Nevada Visibility FIP will allow for reasonable progress toward the national visibility goal with respect to the MGS's contribution to visibility impairment at GCNP due to SO<INF>2</INF> emissions according to the criteria set forth in Section 169A(g)(1) of the Clean Air Act.
