Two congressional subcommittees are holding a joint hearing Tuesday on the role of a coal-fired power plant on the Navajo Nation.
The hearing comes as the U.S. Environmental Protection Agency considers whether to require further reduction of nitrogen oxide emissions from the Navajo Generating Station in Page.
The plant provides hundreds of jobs to American Indians but spews thousands of tons of emissions that cloud the view at the Grand Canyon and other parks.
Officials from the Navajo Nation, the Hopi Tribe and the Gila River Indian Community are scheduled to testify at the hearing. The witness list also includes the general manager of Salt River Project, which operates the plant.
Two environmentalists say they’ll present information on phasing out coal in favor of renewable energy.
