Uranium Recovery Sites Undergoing Decommissioning (NRC)
Contaminated groundwater from radioactive waste dump near Tuba City migrating towards Hopi drinking water spring
After years of unsuccessfully petitioning various federal agencies to remove radioactive waste at a dump near Tuba City, Hopi officials now say any cleanup might come too late.
A plume of contaminated water has migrated to within one-third mile of a spring the Hopi village of Lower Moencopi uses for drinking water, new data shows.
But the EPA does not consider the dump an emergency cleanup site, and at this point, village drinking water is still safe, according to EPA standards.
That could change very soon, however. Two out of three testing wells -- those located closer to the dump -- are registering levels of radioactive water slightly above what is federally considered safe in drinking water, according to hydrogeologist Mark Miller, a consultant contracted by the tribe.
One of those wells sits at the same elevation as the spring used by Lower Moencopi.
"This is a major concern of ours," said Bill Havens, special assistant to Hopi Chairman Ben Nuvamsa.
The contaminated water has reached the canyon used to water nearby crops, raising health concerns about potentially tainted corn, beans and melons.
"It's close enough to the water that we irrigate with from Pasture Canyon that we need more conclusive data and some action to start doing something about the cleanup," said Lorena Naseyowma, assistant community services administrator for Lower Moencopi.
The unlined dump was opened by the Bureau of Indian Affairs decades ago and covered over with dirt and sand when it was closed in 1997. Cleanup is estimated to top $23 million and would require pumping contaminated water from the ground.
There is currently no plan to clean up the dump, although meetings are scheduled later this month between Hopi officials and federal regulators.
A chemical analysis has linked waste found in the dump to byproducts of a uranium mill formerly located a few miles from Tuba City.
The Department of Energy has previously dismissed any such link.

House Committee appalled at federal agencies' incompetence to deal with mess left from Cold War era uranium mining on Navajo land
On October 23, 2007, the U.S. House of Representatives Committee on Oversight and Government Reform
held a Hearing on the Health and Environmental Impacts of Uranium Contamination in the Navajo Nation. The Committee was appalled by the obvious incompetence of the involved federal agencies (EPA, DOE, NRC, IHS, BIA) to deal with the legacy left from historic uranium mining on Navajo land, although the situation is notorious for decades. The Committee urged the agencies to tackle the problem without further delay and to identify any areas where Congressional action may be required.

Aerial survey of abandoned uranium mines identifies excess radiation areas
"Aerial radiological surveys of forty-one geographical areas in the Navajo Nation were
conducted during the period of October 1994 through October 1999. [...]
The aerial survey and subsequent processing characterized the overall radioactivity
levels and excess bismuth-214 activity (indicator of uranium ore deposits and/or
uranium mines) within the surveyed areas. A total of 772,000 aerial gamma spectra
and associated position parameters were obtained and analyzed during the multi-year
operation. The survey determined that only 15 square miles (39 square kilometers) of
the 1,144 square miles (2,963 square kilometers) surveyed (approximately 1.3 %) had
excess bismuth indications above the minimum reportable activity, thus reducing the
area requiring further investigation by a nominal factor of 76."

Tribe urges cleanup for radioactive homes
"...thousands of Navajo men who worked in hundreds of
uranium mines across the reservation from the late 1940s through the
1970s, mining the fuel for America's nuclear weapons arsenal.
The miners found that with a little chipping, the waste ore rocks from
mines could be squared up for excellent building material for walls,
floors and foundations." [...]
"The Navajo tribe's office of the Navajo Abandoned Mine Lands
Reclamation Program has identified 1,300 abandoned uranium mines. Since
1989, about half the mines have been sealed with concrete and other
materials. But piles of exposed uranium ore waste rock remain. The rock
can contain 'hot spots' of uranium ore.
Even where mine reclamation has occurred, there are waste rock houses
left standing or only partially dismantled. And because traditional
Navajo families are sheepherders who live spread out from one another –
their high desert homeland covers parts of Arizona, Utah and New Mexico
– the EPA does not know how many uranium homes exist on the reservation."

Forest Service releases cleanup plan for abandoned Juniper uranium mine
The Forest Service today announced that the Engineering Evaluation and Cost Analysis (EC/CA) for the Juniper Uranium Mine Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) project is available for a 30-day public review and comment period, with comments on the document due by August 27, 2005.

Forest Service closes access to abandoned Juniper uranium mine site
On June 10, 2003, the Forest Service announced the closure of Forest Road 5N33 and the abandoned Juniper Uranium Mine area. New data indicates piles of waste rock emit more radiation than previously detected. At some locations within the site where levels reach 11 mrems an hour [0.11 mSv/h], human exposure to gamma radiation would exceed the EPA's recommended Maximum Dose Limit (MDL) of 15 mrem per year [0.15 mSv/a] when the exposure duration exceeds an hour and a half. The Forest Service has determined that erosion may have exposed gamma-emitting material to the surface, and that water runoff has contaminated about a half mile of Red Rock creek. The Forest Service is closing the area, fencing it off and posting warning signs.
The Juniper Mine site is located at 8,500 feet [2590 m] elevation on the Stanislaus National Forest, south of Sardine Meadow. The mine operated from 1956 to 1966 under private ownership and produced approximately 500 tons of uranium ore for processing in Salt Lake City, Utah. (USDA Forest Service release June 10, 2003 )
Cleaning up the site will take about two years and $2 million dollars from the federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). That cleanup work will involve putting all waste rock left over from the mining process back into the pit and burying it. (Union Democrat June 10, 2003)

Proposal for uranium mill tailings deposit in former Maybell uranium mine
The U.S. Department of Energy has filed an application
requesting the Secretary of the Interior to withdraw from surface entry
and mining and transfer jurisdiction of 160 acres of public land in
Moffat County, Colorado, to be utilized as a uranium mill tailings
disposal site. This notice segregates the land for a period of 2 years
from surface entry and mining.
Comments and requests for a public meeting must be received January 26, 2006.

On Aug. 17, 2005, members of grassroots organization Moffat County Cares submitted a letter to the Colorado State Board of Land Commissioners opposing Standard Uranium's request to lease 1,100 acres north of Juniper Springs. The company's goal is to mine uranium on that lease in conjunction with 15 square miles it already holds the rights to.
(Craig Daily Press, Aug. 18, 2005)
Northwest Colorado Cares is a group of residents that formed after they heard that a Northwest Colorado landowner, Jim Ross, had plans to use the pits left by uranium mining on his property in the 1950s as a dump site for low-level radioactive waste. Ross has said he'd like to fill the pits primarily with spoil piles -- the overburden of dirt that was removed while uranium was being mined. Standard Uranium, a Canadian business, has bought the mining claims to 10,000 acres near Maybell and has the opportunity to lease an additional 2,400.
(Craig Daily Press, July 12, 2005)
A decision by the Colorado Department of Public Health and Environment to encourage Eastern Slope communities to accept low-level radioactive waste has the attention of a Craig group already opposing a proposed site in Moffat County.
Terrie Barrie, chairwoman of Northwest Colorado Cares, said the move could make it easier for local real estate agent Jim Ross to collect low-level radioactive waste in pits in his property that were originally dug to mine uranium.
(Craig Daily Press, June 13, 2005)
A preliminary proposal to retool a defunct uranium mine to accept uranium tailings was presented at the Craig/Moffat County Economic Development Partnership (EDP) meeting on Nov. 17, 2004.
Jim Ross, owner of Intermountain Realty in Craig, received a $6,500 EDP Growing Local Business grant to process more than 25,000 pages of documentation about other repository sites and the history of the former uranium mine located on his property outside of Maybell.

License No.: Colorado RML # 317-02 (Hecla Mining Co.)
NRC demands re-installation of monitoring wells at Durita uranium mill site
In a letter dated December 2, 2005, NRC finds that the Colorado Department of Public Healh and Environment's permission to Hecla Mining Co. to discontinue the groundwater detection monitoring program and plug the wells prior to license termination was premature. The NRC now demands that Hecla installs new monitoring wells.
In a letter dated March 9, 2006, NRC reinforced its view.
CDPHE issues Draft Completion Review Report for decommissioning of Durita heap leach site

Study finds no increased mortality among residents near former Uravan uranium mill
A cohort mortality study was conducted of all adult residents who ever lived in
Uravan, Colorado, a company town built around a uranium mill. Vital status was
determined through 2004 and standardised mortality analyses conducted for 1905
men and women alive after 1978 who lived for at least 6 months between 1936 and
1984 in Uravan.
This community cohort study revealed a significant excess of lung cancer among males who had been employed as underground miners. The authors attribute this excess to the historically high levels of radon in uranium mines of the Colorado Plateau, coupled with the heavy use of tobacco products. There was no evidence that environmental radiation exposures above natural background associated with the uranium mill operations increased the risk of cancer.
Mortality among residents of Uravan, Colorado who lived near a uranium mill, 1936-84, by Boice JD Jr, Cohen SS, Mumma MT, et al., in: Journal of Radiological Protection, September 2007, Vol. 27 (No.3), p.299-319
Funding awarded for Uravan Mine Restoration project
On February 11, 2005, Colorado's Natural Resource Trustees authorized nearly
$2.1 million for three projects designed to enhance natural resources in the Uravan area in western Colorado with funds from the Uravan Superfund cleanup.
One of these projects is the Uravan Mine Restoration project, which receives $852,000 for abandoned uranium mine reclamation and stream restoration adjacent to the Uravan mining and milling site.
The funding for the projects came from an award to the state from the UMETCO Minerals Corporation in a 1987 settlement resulting from environmental damages resulting from mining and milling activity on the site near Uravan.

Former Uravan residents sue Umetco in suspected radiation-related illnesses
A group of Coloradans has sued Union Carbide, saying the firm failed to protect them from deadly radiation when they lived near a company uranium mine.
The 28-page suit filed on Jan. 23, 2004, in U.S. District Court in Denver accuses the company of causing the death from radiation exposure of four people and illness among more than 70 others.
Union Carbide took over a uranium mine and mill in Uravan in 1928 and ran them until 1984. By 1986, contamination forced evacuation of the town south of Grand Junction along the Dolores River.

Disposal of off-site material at Uravan uranium mill site
Umetco Minerals Corp., a wholly owned subsidiary of Union Carbide , is seeking renewal of its license to dispose of 600,000 cubic yards (460,000 m3) off-site contaminated material at the site of its former Uravan uranium mill. The company plans to bid early in 2001 for an EPA project to remove some 94,000 cubic yards (72,000 m3) of contaminated waste from the old Shattuck Chemical Co. site in Denver and dispose of it at its Uravan site.
The license renewal is being opposed by the environmental group Western Colorado Congress (WCC) .
Public Hearings on the issue were held at Naturita, Colorado, on November 15/16, 2000.
On June 8, 2001, Judge Richard Dana, of Judicial Arbiter Group, Inc., approved the renewal of Umetco's state-issued radioactive material license, but imposed conditions. He concluded that some fears voiced by an environmental group were unfounded.
Western Colorado Congress, which had opposed the license renewal, also claimed victory. It cited license conditions that regulate offsite waste disposal at the facility. (Rocky Mountain News June 8, 2001)
In July 2001, the U.S. Environmental Protection Agency has decided not to truck waste from the Shattuck Chemical Co. site to Uravan. Instead, the waste will be shipped by rail to one of three sites already operating under a federal contract. Those sites are in Idaho, Utah and Texas. (Denver Post July 7, 2001)

High radiation levels from abandoned uranium mines also found in Pryor Mountains (Montana) near Bighorn Canyon
High levels of radioactivity found at abandoned uranium mines in the Pryor Mountains has prompted the Custer National Forest to close one area and the Bureau of Land Management to consider closures at other nearby sites.
The Forest Service took radiation readings at the Sandra and Old Glory mines after an abandoned mines inventory suggested they may have high radiation levels. The mines are just west of Crooked Creek above Demijohn Hollow and southeast of the Red Pryor Ice Cave.
At the Sandra Mine, the Forest Service found readings that ranged from 1.8 times the natural background level to 369 times.
After finding the high radiation levels, the Forest Service notified the BLM. BLM lands in the Pryors also contain abandoned uranium mines.
On July 1, the BLM took readings at the Marie, Lisbon and Dandy mine sites, which are just south of the mines on Forest Service land. The highest readings were found at the Lisbon Mine, where radiation near the mouth of the mine measured 2 rems per hour [?!? presumably should read 2 millirems per hour], said Chuck Ward, a BLM ranger.

State to reclaim abandoned Belfield uranium mine
North Dakota's Public Service Commission's Abandoned Mine Lands Division plans to reclaim an old open pit uranium mine northwest of Belfield in summer 2004, using about $1.5 million from the federal Abandoned Mine Lands program. It is a relatively small mine, about 15 acres [6 ha], and one of the last known uranium mines in southwestern North Dakota, where uranium was mined in several locations in the 1950s and 1960s.

Congo high grade tailings to be trucked to Texas Low-Level Waste site for interim storage
Waste Control Specialists has applied to the Texas Department of State Health Services to amend the license for its Low Level Waste site in Andrews County, Texas, so it can store uranium tailings from a former U.S. Department of Energy uranium processing plant in Fernald, Ohio. Originally, the Department of Energy was going to send the silo waste to the Nevada Test Site. But the State of Nevada has threatened to sue DOE if silo waste is sent there, so DOE is considering other options.

On April 28, 2005, DOE announced that the silo waste will be stored at the Waste Control Specialists site in Texas. The agreement covers two years of interim storage at the site. DOE still owns the waste and will look for a long-term storage or disposal arrangement. Waste Control also wants to dispose of the waste and has an application pending with the Texas Department of State Health Services.

Cleanup of Silos 1 and 2 begins
The cleanup of Silos 1 and 2 (also known as K-65 Silos) has begun. The silos contain the uranium mill tailings left over from the processing of extremely high grade uranium ores received in the late 1940's and early 1950's from the Shinkolobwe mine in then Belgian Congo (now DR Congo). It is planned to remove the 8,890 cubic yards [6,796 m3] of so-called "high activity low-level waste"(!) from the two concrete silos and store them in steel transfer tanks, then to chemically stabilize the waste and ship it off site for disposal.

It is also estimated that Silos 1 and 2 contain more than 28 t of uranium; other significant metals include more than 118 t of barium, 830 t of lead, and 2.6 t of arsenic (t = metric ton).
Air samples collected in 1987 from the unfilled, upper portions of Silos 1 and 2 showed maximum radon concentrations of 30 million pCi/l [1.11 billion Bq/m3], that is approx. 60 million times background. External radiation monitoring on top of the silo domes showed exposure rates in excess of 200 mrem/h [2 mSv/h], that is approx. 20,000 times background. The silo contents was later covered with a bentonite clay layer to reduce radon emanation and gamma radiation.
Based on the concentrations of Ra-226, the original ore grade of the uranium ore processed can be estimated at approx. 54% U (Silo 1) and 37% U (Silo 2). The total amount of uranium contained in the original ore processed can be estimated at 11,080 t U (t = metric ton).

Reclamation of White King and Lucky Lass mines to start in summer 2005
Cleanup work begins this summer and is expected to take two summer seasons. Kerr-McGee Chemical Worldwide, Fremont Lumber Co. and Western Nuclear will pay the $8 million cleanup cost. Kerr-McGee is the successor to the Lakeview Mining Co., which was formed by Lakeview-area people whom the energy commission recruited to conduct mining activities from 1955 to 1959.
At White King excavation pond, both the surface water and the ground water are contaminated, as are sediments. The pond covers about three acres and is 70 feet deep.
The most contaminated soil from both mines is to be combined and covered. The acidic water in the White King pond is to be neutralized.
About 430,000 cubic yards, from the White King overburden stockpile, 35,000 cubic yards of off-pile material and 15,000 cubic yards of haul road material will be excavated, consolidated and relocated atop a 138,000-cubic-yard stockpile.
The materials will be covered with "clay-like" material. A 2-foot soil cover will be placed over the 25-acre repository. Vegetation will be re-established atop the cover. The pond will be fenced to discourage use.
After excavation, the disturbed areas, which are expected to cover about 36 acres, will be reclaimed and revegetated.

One-man 'occupation' of Slim Buttes protests slow clean-up of old uranium mines
Harold One Feather is waging a one-man protest to spur the U.S. Forest Service into a quicker clean-up of an old uranium mine in the Slim Buttes in northwestern South Dakota.
One Feather, founder of the new Grand River Environmental Equality Network, said he was "occupying" the Slim Buttes, which are part of Custer National Forest.
The Grand River runs from Custer National Forest through several communities on the Standing Rock reservation, about 60 miles to the east.
One Feather and other Standing Rock residents say runoff from uranium mines may be making people on the reservation sick, though the Forest Service denies that charge.

New study shows environmental pollution from abandoned uranium mines in Cave Hills area, but no health problems determined
Abandoned uranium mines in northwestern South Dakota are polluting nearby waters, but a new study doesn't determine if that has caused health problems downstream. A School of Mines engineering professor says creeks flowing out of the Cave Hills north of Buffalo contain greatly elevated levels of uranium and arsenic, but the chemicals are undetectable less than ten miles downstream. The water is not used for drinking, and state data show normal cancer rates in the area. (AP Sep 12, 2006)

Hazard cleanup at abandoned uranium mines in Harding County may cost $20 million
The clean up at abandoned uranium mines in Harding County will cost an estimated $20 million, according to the U.S. Forest Service.
The agency hopes to have the Riley Pass Uranium Mines site included in the Environmental Protection Agency's Superfund program.
Hazardous materials contaminate 12 bluffs in the Sioux Ranger District of Custer National Forest, said Laurie Walters-Clark, on-scene coordinator of the project.
In the 1950s, uranium mining claims were filed on the 65,000 acres of the North Cave Hills, South Cave Hills and Slim Buttes areas. By 1965, the mining companies had left.
In 1989, the Forest Service built five catch basins to trap sediment washing down from the former mine sites. By the next year, the Forest Service removed more than 6,700 cubic yards of sediment from the basins. With an estimated $2 million price tag, Forest Service officials decided against further reclamation efforts.
Later soil testing showed the bluffs as sources of hazardous substances.
The Forest Service is taking public comment on its plan and will hold public meetings to explain the clean up measures that were chosen, Walters-Clark said.

Group calls for action on abandoned uranium mines
Uranium mines in northwestern South Dakota that were abandoned decades ago without being cleaned up pose health threats and other problems, residents and others say.
Defenders of the Black Hills , a group of volunteers that works to ensure that the United States government upholds the Fort Laramie Treaties of 1851 and 1868, sponsored a meeting on Feb. 26, 2005, to learn more about the mines. The mines are located in the Cave Hills area northwest of Buffalo in Harding County, considered sacred by many American Indians. They are located on public lands managed by the Custer National Forest .
Beginning in the late 1940s, more than 200 uranium mines were dug in South Dakota. The Cave Hills area contains 27 which were abandoned by the companies that originally dug them. They have been polluting the air, land and water for the past 50 to 60 years, members of the group said.

Plateau Resources to decommission Shootaring Canyon uranium mill
On October 24, 2002, Plateau Resources requested a change in its License status from operational to reclamation and submitted a Reclamation and Decommissioning Plan (RDP) for its Shootaring Canyon uranium mill. The mill had been in operation during 76 days in 1982 only and has since been held on stand-by.
"Plateau Resources, Ltd. is planning to decommission its uranium mill, referred to as the
Shootaring Canyon Uranium Project. The mill is licensed to operate under a U. S. Nuclear
Regulatory Commission (NRC) source material license (SUA-1371). The mill operated for a
very limited period of time and the tailings facility contains only 25,000 C.Y. of tailings
material. An additional volume of 39,100 (18,907 tons Hanksville and 26,500 C.Y. Hydro-Jet)
C.Y. of 11.e(2) material exist in the east and north dikes from the cleanup of the Hanksville
buying station and the Hydro-Jet plant. Interim cover placed over the tailings is 39,310 C.Y. An
additional 114,000 C.Y. of contaminated materials are planned to be added to the tailings cell."
[1 C.Y. = 0.765 cubic meters]

NRC approves relaxed groundwater standards for Lisbon mill site
In a draft Environmental Assessment (EA) of January 2004, NRC concludes that the relaxed groundwater standards would have no significant impact:
"On the basis of the draft EA, NRC concluded
that there would be no significant environmental impacts from the proposed action.
Accordingly, the staff has determined that there is no need to prepare an Environmental Impact
Statement for the proposed action. A Finding of No Significant Impact will be published in the
Federal Register if there are no significant concerns noted by the consulted agencies."
By letter dated Feb. 3, 2004, NRC requested the Utah Department of the Environment to provide any comments within 30 days.

WA Dept. of Health and NRC terminate Sherwood license
The Sherwood uranium mill near Wellpinit, operated by Western Nuclear, Inc. from 1978 to 1984, on March 9, 2001, received license termination by the state Department of Health.
> View WA DOH release March 9, 2001
On March 9, 2001, the U.S. Nuclear Regulatory Commission (NRC) concurred with the State of Washington’s decision to transfer the Sherwood Uranium Mill Tailings Radiation Control Act of 1978 (UMTRCA) Title II Site to the U.S. Department of Energy (DOE) Grand Junction Office (GJO) for long-term custody.

Open questions related to proposed License Termination
"On June 21, 2000, staff from the Division of Fuel Cycle Safety and
Safeguards (FCSS) met with state of Washington personnel to determine if
the Sherwood tailings embankment located near Spokane, Washington, should
be classified as a dam under the Federal Guidelines for Dam Safety.
Contractors from the Federal Energy Regulatory Commission (FERC)
accompanied FCSS staff. If the structure meets the Federal definition for a
dam, procedures for license termination and costs for long-term
surveillance and monitoring may be affected.
Embankment design information was reviewed, and questions related to dam
stability, liquefaction, and surface disruption from seismic events were
discussed. A preliminary determination of the dam classification will be
made, and the FERC report will identify additional information that may be
required for the final assessment."
