Intermountain ranked 82nd on list of most polluting power plants in terms of coal waste

In January 2009, Sue Sturgis of the Institute of Southern Studies compiled a list of the 100 most polluting coal plants in the United States in terms of coal combustion waste (CCW) stored in surface impoundments like the one involved in the TVA Kingston Fossil Plant coal ash spill. The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.

Intermountain Power Station ranked number 82 on the list, with 333,589 pounds of coal combustion waste released to surface impoundments in 2006.

Coal Supplies

Coal for the Intermountain Power Station is purchased from coal mines in Utah, Colorado, and Wyoming through the LADWP coal business group, and delivered to the plant by the Union Pacific Railroad. In 2010, Intermountain Power Station Corporation (IPSC) announced plans to accommodate changes in coal purchases that will require trains of over 120 cars.

LADWP 2010 Integrated Resource Plan

The 2010 Integrated Presource Plan of the Los Angeles Department of Water and Power (LDWP), a strategic plan for the next 20 years, recommended that LADWP add 630 new megawatts of solar capacity by 2020 and 970 megawatts of solar capacity by 2030. The plan recommended 580 megawatts of new wind power by 2020. The plan designated that 40 percent of solar be in-basin. It recommended incentive programs, feed-in tariff schemes, and other mechanisms for promoting solar. The plan recommended ending purchases of power from the coal-fired Navajo Generating Station by 2014, which is five years ahead of the deadline established by California state law. The plan recommends ending use of power from the Intermountain Power Station by 2020, seven years ahead of the scheduled end of such purchases. The plan states that "LADWP is open to a mutually agreeable early compliance plan between the project participants that preserves the site and transmission for clean fossil and renewable generation."
