Black Mesa Trust, an indigenous grassroots Hopi environmental, education and advocacy group serving the Native peoples of Black Mesa in northern Arizona, has called on Environmental Protection Agency Region 9 to support its efforts to require that the coal-based 2250-megawatt Navajo Generating Station (NGS) in Page, Ariz., and the Central Arizona Project that carries water from the Colorado River to Phoenix and Tucson, operate in an environmentally sound and culturally equitable manner.
