    The Colorado Canyons National Conservation Area (CCNCA) is located about 7 miles west of Grand Junction, Colorado. The CCNCA includes rolling saltbush-covered hills, pinyon-junpier and sagebrush-covered mesas, a 24-mile corridor along the Colorado River through Horsethief and Ruby Canyons, and over 70,000 acres of sheer-sided, red-rock canyons, natural arches, caves and alcoves. The 75,550-acre Black Ridge Canyons Wilderness comprises the heart of the CCNCA, with another 5,200 acres stretching into Utah. The CCNCA was given a high priority for land health assessment, a valuable tool in developing the CCNCA Resource Management Plan (RMP)

    This decision document presents the selected interim remedial action for Operable Unit (OU) Ill surface water and ground water at the Monticello Mill Tailings Site (MMTS) in San Juan County, Utah. The selected interim remedial action was chosen in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act as amended by the Superfund Amendments and Reauthorization Act of 1986 and, to the extent practicable, with the National Oil and Hazardous Substances Pollution Contingency Plan (NGP). This decision is based on the administrative record for this site. The State of Utah concurs with the selected interim action. The selected alternative for the interim remedial action for OI Ill surface water and ground water at the MMTS is Alternative 2-implementing institutional controls, continuing Millsite dewatering and treatment of excavation water and surface runoff, continuation of ongoing monitoring efforts, and evaluation of a permeable reactive treatment (PeRT) wall through the use of a pilot-scale treatability study. The PeRT wall is an enhancement to the interim remedial action. This remedial action is only an interim measure. If monitoring results indicate that the interim remedial action is not achieving the objectives of preventing exposure to and reducing contaminants in contaminated ground water, other alternatives will be evaluated from the OU Ill feasibility study. The final remedy for the site surface water and ground water will be documented in the final Record of Decision (ROD) for OU Ill
