Book excerpt: 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).

Available in PDF, EPUB and Kindle. Book excerpt: Surface remedial action at the Gunnison Uranium Mill Tailings Remedial Action Project site began in 1992; completion is expected in 1995. Ground water and surface water will be sampled semiannually at the Gunnison processing site (GUN-01) and disposal site (GUN-08). Results of previous water sampling at the Gunnison processing site indicate that ground water in the alluvium is contaminated by the former uranium processing activities. Background ground water conditions have been established in the uppermost aquifer (Tertiary gravels) at the Gunnison disposal site. Semiannual water sampling is scheduled for the spring and fall. Water quality sampling is conducted at the processing site (1) to ensure protection of human health and the environment, (2) for ground water compliance monitoring during remedial action construction, and (3) to define the extent of contamination. At the processing site, the frequency and duration of sampling will be dependent upon the nature and extent of residual contamination and the compliance strategy chosen. The monitor well locations provide a representative distribution of sampling points to characterize ground water quality and ground water flow conditions in the vicinity of the sites. The list of analytes has been modified with time to reflect constituents that are related to uranium processing activities and the parameters needed for geochemical evaluation.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report evaluates potential impacts to public health or the environment resulting from groundwater contamination at the former uranium mill processing site. The tailings and other contaminated material at this site are being placed in an off-site disposal cell by the US Department of Energy's (DOE) Uranium Mill Tailings Remedial Action (UMTRA) Project. Currently, the UMTRA Project is evaluating groundwater contamination. This is the second risk assessment of groundwater contamination at this site. The first risk assessment was performed primarily to evaluate existing domestic wells to determine the potential for immediate human health and environmental impacts. This risk assessment evaluates the most contaminated groundwater that flows beneath the processing site towards the Gunnison River. The monitor wells that have consistently shown the highest concentration of most contaminants are used in this risk assessment. This risk assessment will be used in conjunction with additional activities and documents to assist in determining what remedial action is needed for contaminated groundwater at the site after the tailings are relocated. This risk assessment follows an approach outlined by the US Environmental Protection Agency (EPA). The first step is to evaluate groundwater data collected from monitor wells at the site. Evaluation of these data showed that the main contaminants in the groundwater are cadmium, cobalt, iron, manganese, sulfate, uranium, and some of the products of radioactive decay of uranium.

This book was released on 2003 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1995 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Uranium Mill Tailings Remedial Action (UMTRA) Project consists of the Surface Project, and the Ground Water Project. For the UMTRA Project site located near Naturita, Colorado, phase I involves the removal of radioactively contaminated soils and materials and their transportation to a disposal site at Union Carbide Corporation's Upper Burbank Repository at Uravan, Colorado. The surface cleanup will reduce radon and other radiation emissions from the former uranium processing site and prevent further site-related contamination of ground water. Phase II of the project will evaluate the nature and extent of ground water contamination resulting from uranium processing and its effect on human health and the environment, and will determine site-specific ground water compliance strategies in accordance with the US Environmental Protection Agency (EPA) ground water standards established for the UMTRA Project. Human health risks could occur from drinking water pumped from a hypothetical well drilled in the contaminated ground water area. Environmental risks may result if plants or animals are exposed to contaminated ground water or surface water that has mixed with contaminated ground water. Therefore, a risk assessment was conducted for the Naturita site. This risk assessment report is the first site-specific document prepared for the Ground Water Project at the Naturita site. What follows is an evaluation of current and possible future impacts to the public and the environment from exposure to contaminated ground water. The results of this evaluation and further site characterization will be used to determine whether any action is needed to protect human health or the environment.

This book was released on 1994 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This baseline risk assessment of ground water contamination at the uranium mill tailings sites near Slick Rock, Colorado, evaluates potential public health and environmental impacts resulting from ground water contamination at the former North Continent (NC) and Union Carbide (UC) uranium mill processing sites. The tailings at these sites will be placed in a disposal cell at the proposed Burro Canyon, Colorado, site. The US Department of Energy (DOE) anticipates the start of the first phase remedial action by the spring of 1995 under the direction of the DOE's Uranium Mill Tailings Remedial Action (UMTRA) Project. The second phase of the UMTRA Project will evaluate ground water contamination. This baseline risk assessment is the first site-specific document for these sites under the Ground Water Project. It will help determine the compliance strategy for contaminated ground water at the site. In addition, surface water and sediment are qualitatively evaluated in this report.

This book was released on 1996 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is the second site-specific risk assessment document prepared for the Ground Water Project at the Gunnison site. A preliminary risk assessment was conducted in 1990 to determine whether long-term use of ground water from private wells near the Gunnison site had the potential for adverse health effects. Due to the results of that preliminary risk assessment, the residents were provided bottled water on an interim basis. In July 1994, the residents and the nearby Valco cement/concrete plant were given the option to connect to anew alternate water supply system, eliminating the bottled water option. This document evaluates current and potential future impacts to the public and the environment from exposure to contaminated ground water. The results of this evaluation and further site characterization will be used to determine whether more action is needed to protect human health and the environment and to comply with the EPA standards.

Book excerpt: 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.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The US Department of Energy (DOE) Uranium Mill Tailings Remedial Action (UMTRA) Project consists of the Surface Project (Phase 1) and the Ground Water Project (Phase 2). Under the UMTRA Surface Project, tailings, radioactive contaminated soil, equipment, and materials associated with the former uranium ore processing sites are placed into disposal cells. The cells are designed to reduce radon and other radiation emissions and to prevent further ground water contamination. The Ground Water Project evaluates the nature and extent of ground water contamination resulting from the uranium ore processing activities. Two UMTRA Project sites are near Rifle, Colorado: the Old Rifle site and the New Rifle site. Surface cleanup at the two sites is under way and is scheduled for completion in 1996. The Ground Water Project is in its beginning stages. A risk assessment identifies a source of contamination, how that contamination reaches people and the environment, the amount of contamination to which people or the environment may be exposed, and the health or environmental effects that could result from that exposure. This report is a site-specific document that will be used to evaluate current and future impacts to the public and the environment from exposure to contaminated ground water. This evaluation and further site characterization will be used to determine if action is needed to protect human health or the environment.
