The U.S. Department of Energy (DOE) is proposing a ground water compliance strategy for the Uranium Mill Tailings Remedial Action (UMTRA) Project site near Durango, Colorado. DOE has prepared this environmental assessment to provide the public with information concerning the potential effects of this proposed strategy.

Download Baseline Risk Assessment of Ground Water Contamination at the Uranium Mill Tailings Site Near Durango, Colorado. Revision 1 Book in PDF, Epub and Kindle
For the UMTRA Project site located near Durango, Colorado (the Durango site), the Surface Project cleanup occurred from 1986 to 1991. An evaluation was made to determine whether exposure to ground water contaminated by uranium processing could affect people's health. Exposure could occur from drinking water pumped from a hypothetical well drilled in the contaminated ground water area. In addition, environmental risks may result if plants or animals are exposed to contaminated ground water, or surface water that has mixed with contaminated ground water. This risk assessment report is the first site-specific document prepared for the UMTRA Ground Water Project at the Durango site. The results of this report and further site characterization of the Durango site will be used to determine what is necessary to protect public health and the environment, and to comply with the EPA standards.

The U.S. Department of Energy (DOE) is in the process of selecting a ground water compliance strategy for the Gunnison, Colorado, Uranium Mill Tailings Remedial Action (UMTRA) Project site. This Environmental Assessment (EA) discusses two alternatives and the effects associated with each. The two alternatives are (1) natural flushing coupled with institutional controls and continued monitoring and (2) no action. The compliance strategy must meet U.S. Environmental Protection Agency (EPA) ground water standards defined in Title 40 ''Code of Federal Regulations'' Part 192, Subpart B, in areas where ground water beneath and around the site is contaminated as a result of past milling operations. It has been determined that contamination in the ground water at the Gunnison site consists of soluble residual radioactive material (RRM) as defined in the Uranium Mill Tailings Radiation Control Act (UMTRCA).

Download Environmental Assessment of Ground Water Compliance at the Naturita, Colorado, UMTRA Project Site Book in PDF, Epub and Kindle
This Environmental Assessment addresses the environmental effects of a proposed action and the no action alternative to comply with U.S. Environmental Protection Agency (EPA) ground water standards at the Naturita, Colorado, Uranium Mill Tailings Remedial Action Project site. In 1998, the U.S. Department of Energy (DOE) completed surface cleanup at the site and encapsulated the tailings in a disposal cell 15 miles northwest near the former town of Uravan, Colorado. Ground water contaminants of potential concern at the Naturita site are uranium and vanadium. Uranium concentrations exceed the maximum concentration limit (MCL) of 0.044 milligram per liter (mg/L). Vanadium has no MCL; however, vanadium concentrations exceed the EPA Region III residential risk-based concentration of 0.33 mg/L (EPA 2002). The proposed compliance strategy for uranium and vanadium at the Naturita site is no further remediation in conjunction with the application of alternate concentration limits. Institutional controls with ground water and surface water monitoring will be implemented for these constituents as part of the compliance strategy. This compliance strategy will be protective of human health and the environment. The proposed monitoring program will begin upon regulatory concurrence with the Ground Water Compliance Action Plan (DOE 2002a). Monitoring will consist of verifying that institutional controls remain in place, collecting ground water samples to verify that concentrations of uranium and vanadium are decreasing, and collecting surface water samples to verify that contaminant concentrations do not exceed a regulatory limit or risk-based concentration. If these criteria are not met, DOE would reevaluate the proposed action and determine the need for further National Environmental Policy Act documentation. No comments were received from the public during the public comment period. Two public meetings were held during this period. Minutes of these meetings are included as Attachment 1.

Download UMTRA Project Water Sampling and Analysis Plan, Durango, Colorado. Revision 1 Book in PDF, Epub and Kindle
Planned, routine ground water sampling activities at the US Department of Energy (DOE) Uranium Mill Tailings Remedial Action (UMTRA) Project site in Durango, Colorado, are described in this water sampling and analysis plan. The plan identifies and justifies the sampling locations, analytical parameters, detection limits, and sampling frequency for the routine monitoring stations at the site. The ground water data are used to characterize the site ground water compliance strategies and to monitor contaminants of potential concern identified in the baseline risk assessment (DOE, 1995a). Regulatory basis for routine ground water monitoring at UMTRA Project sites is derived from the US EPA regulations in 40 CFR Part 192 (1994) and EPA standards of 1995 (60 FR 2854). Sampling procedures are guided by the UMTRA Project standard operating procedures (SOP) (JEG, n.d.), the Technical Approach Document (TAD) (DOE, 1989), and the most effective technical approach for the site.
