The statement assesses impacts associated with mining up to 11 million tons of oil shale and subsequent construction and operation of a full-size oil shale module at the Anvil Points Oil Shale Facility in Garfield County, Colorado. Modeling results predict that the facility will comply with all Federal ambient air quality standards. Land disturbance during the 18-month construction period is expected to cause 600 to 80,000 tons of sediment loading in the Colorado River, depending upon the use of runoff control techniques. Retort process water will be deposited in the Balzac Gulch retorted shale disposal site.
