EPA Approves Plan to Retire Coal-fired Unit in Arizona
LCG, July 30, 2014-The Environmental Protection Agency (EPA) approved on Monday a plan to retire a coal-fired unit at the Navajo Generating Station in 2019. The 750-MW unit is one of three units at the 2,250-MW electric generating station. The station is located on the Navajo Indian Reservation near Page, Arizona, approximately 20 miles from the Grand Canyon.
In July 2013, the plant owners proposed retiring a unit by 2020 to avoid an EPA requirement to install pollution-control devices to reduce nitrogen oxide emissions. The plan approved by the EPA further includes the retirement of the Navajo Generating Station by 2044.
The owners of the Navajo Generating Station are Los Angeles Department of Water and Power (477 MW), NV Energy (254 MW), Bureau of Reclamation (547 MW), SRP (488 MW), Arizona Public Service (315 MW) and Tucson Electric Power (169 MW). Retirement of the 750-MW unit aligns with intent of Los Angeles Department of Water and Power and NV Energy to divest from coal-fired power generation assets.
The Navajo Generating Station is the largest coal plant in the U.S. West and began operations in the mid-1970s.
