10/8/2011 Gallup Independent: Udall urges continued cleanup of area's legacy uranium sites

10/8/2011 Udall urges continued cleanup of area’s legacy uranium sites By Kathy Helms, Dine Bureau, Gallup Independent: WINDOW ROCK – U.S. Sen. Tom Udall, D-N.M., received commitments Thursday from three federal agencies that they will continue to work together to clean up uranium contamination on the Navajo Nation. Officials from the U.S. Environmental Protection Agency, U.S. Department of Energy, and U.S. Nuclear Regulatory Commission testified on the status of cleanup operations at legacy uranium mining and milling operations. The testimony was presented during a federal oversight hearing before the U.S. Senate Environment and Public Works Subcommittee on Children’s Health and Environmental Responsibility, which Udall chairs. The senator stressed that each agency continue ongoing cleanup projects and commit to providing necessary funding for the Five-Year Plan for the Navajo Nation begun in 2007 and a Five-Year Plan begun last year for the Grants Mining District.

“Recently, the Navajo Nation informed EPA that they intend to request a second five-year review plan,” James Woolford, director of Superfund Remediation and Technology Innovation, said. “The agency plans to work with the Navajo Nation and our colleagues to put together that plan over the next year.” EPA is the lead federal agency for the cleanup plan.

EPA has been obligating about $12 million per year for Navajo cleanup efforts. However, the federal government is operating under a continuing resolution so EPA cannot commit to a particular figure for the upcoming year, he said.

David Geiser, director of the Department of Energy’s Office of Legacy Management, said DOE contributes about $4 million for the four legacy uranium mill sites it monitors on Navajo. In 2009, DOE received a $5 million special appropriation for cleanup of the Highway 160 site outside of Tuba City. That work was completed in August, he said.

Udall applauded EPA for its recent announcement of an approved plan to clean up the Northeast Churchrock Mine, the highest-priority abandoned uranium mine on the Navajo Nation, and also raised concerns about Tuba City contamination.

“Since 1995 there have been more than 35 studies conducted on the Tuba City Open Dump,” Udall said. He asked whether they knew the source of contamination or whether there was a cleanup plan.

Woolford said the Hopi Tribe submitted a study to EPA in August which concluded there was groundwater contamination adjacent to the dump. “We’re currently reviewing it and we have plans to meet with the tribe at the end of October to go over the study.”

He said EPA has an enforceable agreement with the Bureau of Indian Affairs to conduct a comprehensive investigation and feasibility study to ascertain whether the dump is contaminating the groundwater. “The groundwater is contaminated. Everyone knows that. We are not 100 percent sure of the source,” he said.

“Does the Tuba City Open Dump site pose a threat to drinking water for the Navajo Nation or the Hopi Tribe?” Udall asked.

“Yes, we believe it does,” Woolford said, however a cleanup remedy is contingent on the outcome of the BIA study.

Geiser said both Navajo and Hopi believe mill tailing material was disposed of in the open dump and that it is the source of the uranium contamination, but he said there is no evidence to support that claim. “There have been over 200 borings taken of the open dump, and none of them found mill material,” he said.

DOE also doesn’t believe there is a hydrological connection between the Tuba City uranium mill tailings disposal cell and the Moenkopi village wells, Geiser said.

Udall asked for further details on the Northeast Churchrock cleanup and a potential time-line. Woolford said they ultimately chose “a pretty simple remedy,” which is to move more than 870,000 cubic yards of contaminated waste rock and more than 100,000 cubic yards of contaminated soil “almost across the street” to the United Nuclear Corp./General Electric Superfund site.

Beginning this fall, community members will be offered relocation opportunities, according to Woolford. Clancy Tenley of EPA Region 9 said Monday that residents could take a temporary move-out of their house during the cleanup, “but that would be in a hotel for potentially years,” or they could take advantage of an EPA “cash-out” offer for a permanent residence of comparable value.

Geiser said EPA approached DOE about two years ago with the idea of combining mine waste with the mill waste. “For the last 10 to 12 years, the department has agreed to accept non-mill waste in the disposal cells under certain conditions,” he said. Northeast Churchrock would be the “single largest volume” of that type material to be put in a disposal cell.

NRC’s Weber said they will prepare an environmental assessment to support a revision to the reclamation plan for UNC’s tailings impoundment and there will be opportunity for public comment on the UNC license amendment. Barring any legal challenges or glitches, cleanup could be done by 2018 or 2019 with DOE’s Legacy Management as the ultimate overseer.

10/7/2011 Udall Holds Oversight Hearing on Federal Efforts to Clean Up Uranium Contamination

10/7/2011 Udall Holds Oversight Hearing on Federal Efforts to Clean Up Uranium Contamination Original Author: Democracy for New Mexico: U.S. Senator Tom Udall (D-NM), chairman of the U.S. Senate Environment and Public Works Subcommittee on Children’s Health and Environmental Responsibility, held an oversight hearing yesterday on the status of cleanup operations at legacy uranium mining and milling operations in New Mexico and elsewhere in the United States. Officials from the U.S. Environmental Protection Agency (EPA), U.S. Department of Energy (DOE), and U.S. Nuclear Regulatory Commission (NRC) testified before the subcommittee about federal cleanup efforts.

During World War II and the Cold War, the federal government relied on extensive uranium prospecting and development throughout the country and especially in uranium-rich areas of the southwest. The uranium industry emerged overnight, at a time of minimal understanding or protection for individuals and the environment. The resulting radiological contamination created a legacy of sickness and pollution, a statement released about the hearing explained.

“The story of uranium development in the United States is a human story, and a tragic human story,” Udall said. “Even as the understanding of the dangers grew, the federal government failed to ensure that uranium workers and their families were safe from the hazards of exposure to radioactive materials.”

Navajo communities have seen some of the worst contamination. One of the most catastrophic examples, the collapse of the United Nuclear Corporation uranium mill tailings facility near Church Rock, NM, ranks as the largest accidental radiation release in U.S. history.

After Congressional hearings began to shine a light on the radiological contamination decades later, EPA, other agencies, and responsible private sector companies undertook the process of cleaning up thousands of abandoned uranium mines, and numerous mill and mine sites. Much work remains to be done.

Testimony: 3 Federal Officials
Udall questioned three key officials from different federal agencies about their commitment to continuing cleanup operations. All three pledged future support and acknowledged that significant work remains. Video of that questioning is available by clicking here.

“The Department of Energy established the Office of Legacy Management in 2003, with the express purpose of having a long-term, sustainable management of closed sites,” said David Geiser, director of DOE’s Office of Legacy Management. “So today we have 87 sites around the country that Legacy Management is responsible for…The Department set up the office explicitly for that long-term purpose.”

Udall stressed that each agency continue the ongoing cleanup projects and commit to providing necessary funding, especially for the Five-Year Plans for the Navajo Nation and the Grants Mining District.

“EPA has led the development and implementation of a coordinated federal plan to address the uranium legacy on the Navajo Nation,” said James Woolford, director of Superfund Remediation and Technology Innovation for the EPA’s Office of Solid Waste and Emergency Response. “EPA maintains a strong partnership with the Navajo EPA, and, since 1994, EPA has provided technical assistance and funding to assess potentially contaminated sites and develop and implement response actions.”

Woolford reported that the EPA spends $12 million annually for cleanup efforts on the Navajo Nation, in addition to $4 million annually from DOE and a $5 million special appropriation for reclamation of a contaminated site near Tuba City, AZ. Udall commended the EPA for its recently announced plan to clean up the Northeast Church Rock site, the largest abandoned mine on the Navajo Nation and highest risk site in New Mexico, but sought further details on how that plan would be implemented.

Regulating Future Uranium Mining
The hearing also focused on proposed future uranium mining operations. Udall pressed the EPA and NRC, which jointly regulate these kinds of operations, to ensure that new uranium mining does not lead to future contamination. Many communities with legacy contamination are still waiting for cleanup while new mining is being proposed at, or near, the same sites.

“While cleanup is moving decades after the initial contamination, some of these communities are faced with new proposals to re-start uranium mining for energy purposes, opening up old wounds, and arousing new passions,” said Udall. Michael Weber, deputy executive director for the NRC’s Materials, Waste, Research, State, Tribal, and Compliance Programs addressed the regulation of new mining operations.

“The NRC’s comprehensive regulatory framework ensures safe operation and decommissioning of the existing facilities, as well as any planned facilities. The Agency’s standards conform to standards promulgated by EPA,” said Weber. “After a license is issued for a new uranium recovery facility, the NRC or Agreement State provides continued oversight of the operations through periodic licensing reviews, inspections, assessment, enforcement, and investigations.”

Concerns on Proposed Mine Near Crownpoint
Pressing the NRC on their commitment to ensure safe operation and decommissioning of existing and new uranium processing facilities, Udall raised concerns about a proposal for a new NRC-regulated mine near the community of Crownpoint. In response, the NRC testified that the “unique” requirements of the permit and the regulations in place would ensure a continued and safe drinking water supply for the community of Crownpoint should the proposed mining goes forward.

Working Together
Udall urged federal agencies to prioritize existing cleanup operations and to continue to work together, coordinating with state and tribal governments, to assist communities that have been impacted by uranium contamination. In response, the three federal agencies committed to further public involvement as cleanup plans continue.

DOE: Techlines provide updates of specific interest to the fossil fuel community

DOE: Techlines provide updates of specific interest to the fossil fuel community. Some Techlines may be issued by the Department of Energy Office of Public Affairs as agency news announcements: Projects Aimed at Advancing State-of-the-Art Carbon Capture from Coal Power Plants Selected for Further Development: Washington, D.C. — Four projects aimed at reducing the energy and cost penalties of advanced carbon capture systems applied to power plants have been selected for further development by the U.S. Department of Energy’s Office of Fossil Energy (FE).

Valued at approximately $67 million (including $15 million in non-federal cost sharing) over four years, the overall goal of the research is to develop carbon dioxide (CO2) capture and separation technologies that can achieve at least 90 percent CO2 removal at no more than a 35 percent increase in the cost of electricity. This would represent a significant improvement over projected increases in electricity costs using existing technologies.

Advanced CO2 power plant capture systems are a key element in carbon capture, utilization, and storage (CCUS) technologies, considered by some energy experts to be among the important options for reducing greenhouse gas emissions associated with possible climate change. Existing carbon capture systems currently require large amounts of energy for their operation, resulting in decreased efficiency and reduced net power output when compared to plants without CCUS technology. These penalties can add as much as 80 percent to the cost of electricity for a new pulverized coal plant

Today’s selections focus on slipstream-scale development (0.5 to 5 MWe) and testing of advanced solvent-based post-combustion CO2 capture technologies. Post-combustion capture offers great near-term potential for reducing power sector CO2 emissions because it can be added to existing plants.

The projects, managed by FE’s National Energy Technology Laboratory include:

* Linde LLC (Murray Hill, New Jersey) – Slipstream Pilot Scale Demonstration of a Novel Amine-Based Post-Combustion Process Technology for CO2 Capture from Coal-Fired Power Plant Flue Gas

* The proposed project will use a post combustion capture technology incorporating BASF’s novel amine-based process at a 1 MWe equivalent slipstream pilot plant at the National Carbon Capture Center. This technology offers significant benefits as it aims to reduce the regeneration energy requirements using novel solvents that are stable under the coal-fired power plant feed gas conditions. The Department of Energy will contribute $15,000,000 to the project.

* Neumann Systems Group, Inc. (NSG) (Colorado Springs, CO) – Carbon Absorber Retrofit Equipment (CARE)

* This project, located at the Colorado Springs Drake #7 power plant, will design, construct, and test a patented NeuStreamTM absorber. The absorber will use nozzle technology proven during a recently completed 20 megawatt NeuStream-S flue gas desulfurization pilot project, and an advanced solvent that efficiently captures CO2. This absorber technology is applicable to a variety of solvents and can be added to existing pulverized coal power plants with reduced cost and footprint. Because of the modularity of the NeuStream technology, it can be rapidly scaled to larger size systems and retrofitted into existing plants with little risk. The Department of Energy will contribute $7,165,423 to the project.

* Southern Company (Atlanta, GA) – Development and Demonstration of Waste Heat Integration with Solvent Process for More Efficient CO2 Removal from Coal-Fired Flue Gas

* Southern Company will develop viable heat integration methods for the capture of CO2 produced from pulverized coal combustion using a waste heat recovery technology, High Efficiency System. This technology will be integrated into an existing 25 megawatt pilot amine-based CO2 capture process (KM-CDR) at Southern Company’s Plant Barry. Modeling by Mitsubishi Heavy Industries America indicates that a fully heat integrated High Efficiency System will improve by 26 percent the thermal energy performance of the integrated KM-CDR and plant operation. The Department of Energy will contribute $15,000,000 to the project.

* University of Kentucky Research Foundation (Lexington, KY) – Application of a Heat Integrated Post-Combustion CO2 Capture System with Hitachi Advanced Solvent into Existing Coal-Fired Power Plant

* Researchers plan to use an innovative heat integration method that uses waste heat from a Hitachi H3-1 advanced solvent carbon capture system while improving steam turbine efficiency. The proposed process also implements a process concept (working with the heat integration method) that increases solvent capacity and capture rate in the CO2 scrubber.

* The novel concepts and advanced solvent used in this study will significantly improve the overall plant efficiency when integrated with CO2 capture systems, and can be applied to existing coal-fired power plants. The Department of Energy will contribute $14,502,144 to the project.

4/20/2011 Gallup Independent article: Delegate concerned about cleanup of Highway 160 site

Delegate concerned about cleanup of Highway 160 site, By Kathy Helms, Dine Bureau, Gallup Independent, 4/20/2011, WINDOW ROCK – Navajo Nation Environmental Protection Agency has selected a contractor to begin cleanup of the “Highway 160 Site” in Tuba City and will host a Radiation Awareness Workshop next week at To’Nanees’Dizi Chapter House to educate the public, according to Navajo Nation Council Delegate Joshua Lavar Butler. “Area residents need to be reassured that the cleanup and transport of radioactive material is done in an effective and efficient manner without causing further harm to the surrounding area. During the summer it’s windy, and anyone downwind could be affected,” Butler, who represents To’Nanees’ Dizi, said.

“It is vitally important federal and tribal officials begin educating and notifying people of concerns for safety and activities associated with this cleanup. I will continue to keep our people informed and will urge the agencies involved to take all safety precautions to ensure it is done in a manner to protect the health of our people and of our environment,” he said.

The Radiation Awareness Workshop will be held 8 a.m.-5 p.m. April 27-28, with three sessions April 27 for the general public, and two more in-depth sessions April 28 for emergency and public safety personnel, according to Butler.

The Highway 160 Site is located about 5 miles east of Tuba City along Arizona Highway 160. It is directly north of the former Rare Metals uranium mill owned by El Paso Natural Gas and managed by U.S. Department of Energy’s Legacy Management.

According to an October 2010 statement of work, the Highway 160 site was discovered by Navajo EPA in 2003. The agency conducted radiological and soil analysis the following May and released a final report in September 2004. The site was found to have high radiological readings, including a finding of more than 1 million counts per minute.

In 2006 and 2007, Navajo EPA contracted William Walker of Walker & Associates, Inc., to conduct further site investigation. Walker found evidence that linked the contamination to Rare Metals, including ceramic tumblers and Normandy pebbles possibly used in the mill processing operation. Radiological levels ranged from 400 counts per minute to more than 10,000 counts per minute.

Analysis was performed on 47 soil samples and Walker released a final report in 2007 identifying radiological concerns that are affecting the immediate environment as well as health and safety concerns for humans, animals and plants. Groundwater at the Highway 160 site has not been characterized, according to Navajo EPA.

Hopi Tribal Chairman LeRoy Shingoitewa, who lives in the Upper Village of Moenkopi, is concerned, according to Butler. The Highway 160 Site is in close proximity not only to Rare Metals – where DOE has been treating contaminated groundwater for nearly a decade – but also another site known as the Tuba City Open Dump, where radioactive contamination also was found.

“There is some radioactive contamination that is showing up in a plume that is coming off the Tuba City Open Dump,” Shingoitewa said. “The plume is also moving into the drinking water, so both the Hopi Tribe and Navajo Nation are working as partners very closely to make sure that the open dump site will be cleaned up.”

The Highway 160 Site is within the customary use area of a family who used the area to graze their livestock. In late 2007, El Paso provided further surveys of the site and confirmed the presence of buried debris up to 13 feet deep. El Paso fenced nearly 8 acres of the 16-acre site and applied a polymer cover to prevent windblown contamination.

Stephen B. Etsitty, who has been executive director of Navajo EPA since 2003 and was confirmed again Wednesday by Council, said they fought DOE for years for recognition of the site, and finally in Fiscal Year 2009 received congressional authority and a $5 million appropriation through DOE to clean up the site. DOE will keep $500,000 of that amount for oversight of the project. “It will be a clean closure,” Etsitty said, meaning that all contaminated soil will be removed and transported away from the Navajo Nation to an approved disposal facility.

Cassandra Bloedel of Navajo EPA, in an exit interview in January with the 21st Council’s Resources Committee, said the waste will be removed this year, possibly by August, and transported on state highways for final disposal at the “Cheney Cell,” about 12 miles southeast of Grand Junction, Colo.
