(Ross D. Franklin | The Associated Press) This Sept. 4, 2011 file photo shows the main plant facility at the Navajo Generating Station, as seen from Lake Powell in Page, Ariz. The plant's operator says it and other owners are considering options that include keeping it open but also shutting down the massive coal-fired power plant in northern Arizona within a few years. Salt River Project spokesman Scott Harelson says SRP officials recently met with Navajo Nation officials to discuss the plant located on the Navajo reservation near Page.
