ADEQ issues revised draft Air Permit for Arizona 1 uranium mine:
The Arizona Department of Environmental Quality is still working on developing new, more environmentally protective air quality permits for three uranium mines in the Grand Canyon region.
The action comes after news broke late last year that elevated uranium levels had been measured in soils near Pinenut uranium mine, located 10 miles north of the Grand Canyon and owned by Energy Fuels Resources. In response, ADEQ decided to suspend its work on air quality permit renewals for all four uranium mines operated by Energy Fuels Resources.
ADEQ is now working to complete drafts of the new air quality permits for public review and comment. The revisions include faster execution of enhanced dust control measures if elevated uranium or radium levels are detected and extensive changes to the required soil sampling and radiation survey plan to mitigate potential impacts from high wind.
The state department will host public hearings on the new draft permits in Flagstaff, Tuba City and Fredonia, which it hopes to begin in early summer. (Arizona Daily Sun Apr. 15, 2016)

Mining at Arizona 1 mine to cease due to depletion of resources: Subject to the results of additional underground drilling, mining at the Arizona 1 mine is expected to cease in early FY-2014 due to the depletion of its known resources. (Energy Fuels Inc. Nov. 14, 2013)
Court dismisses appeal against reopening of Arizona 1 uranium mine: A federal appeals court has ruled against conservationists and tribes in their challenge of a uranium mine north of the Grand Canyon. The group had sued the U.S. Bureau of Land Management, alleging the agency relied on an outdated and inadequate environmental analysis in allowing the Arizona 1 Mine to resume operation. The 9th U.S. Circuit Court of Appeals ruled Monday (Feb. 4) that the BLM hasn't made any decisions that would trigger a new analysis and that the 1988 operation plan allows for temporary closures. (AP Feb. 3, 2013)
Appeal challenges Arizona 1 uranium mine threatening Grand Canyon:
On Nov. 28, 2011, Conservation groups and American Indian tribes filed an appeal in the 9th Circuit Court challenging a lower court ruling that allowed a uranium mine near Grand Canyon National Park to re-open without updating decades-old environmental reviews. The Arizona 1 uranium mine is located near Kanab Creek immediately north of Grand Canyon National Park.
In 2010, conservation groups and tribes sued the Bureau of Land Management for failing to modernize 23-year-old mining plans and environmental reviews prior to allowing Denison Mines to resume uranium mining after the mine was shuttered in 1992. A federal judge in Phoenix this fall sided with the Bureau and the uranium industry saying no new plans or reviews were needed, prompting today's appeal.
The Arizona 1 is one of four existing uranium mines located in Grand Canyon's 1-million-acre watershed where the Obama administration has proposed a 20-year ban on new mining claims and uranium development on existing claims lacking valid existing rights. A final environmental impact statement was issued for the 1-million acre ban in October; a decision finalizing those protections could come as early as today. (Center for Biological Diversity Nov. 28, 2011)
Reopened Arizona 1 uranium mine largely left to regulate itself:
Denison Mines began hauling ore out of the first and only uranium mine to reopen so far, 35 miles southwest of Fredonia, in December 2009.
State environmental inspectors didn't arrive for a first inspection at the mine until it had already been open for about nine months.
The Arizona Department of Environmental Quality (ADEQ) had unfilled requests for documents and inspections by engineers that it sought before the mine opened.
Mine operators set to work without answering some of these requests.
The first inspection at the mine came in September, and ADEQ inspected at the ground level only, not traveling into the mine that reaches more than 1,252 feet below. Nevertheless, the inspection yielded what ADEQ deemed four "major violations."
Arizona 1 uranium mine operating illegally, EPA says:
A uranium mine north of the Grand Canyon is operating in violation of the law, and its owner could face thousands of dollars in fines as a result, the U.S. Environmental Protection Agency said.
The agency issued a notice of violation this week to Denison Mines Corp. for its Arizona 1 Mine, which is about 20 miles from the Grand Canyon's northern border.
The EPA said Denison failed to notify the agency as to when it would resume mining and that it did not secure the necessary federal approval before ventilating the mine or testing emissions.
Denison President Ron Hochstein said Tuesday (May 4) that he was surprised by the notice and believed the company was operating within the law. He said he was working with regulators to address those issues. (AP May 5, 2010)

Energy Fuels closes Pinenut mine for good, after increased uranium level found in soil nearby: [The Arizona Department of Environmental Quality] reported that Energy Fuels Resources has ceased operations at Pinenut mine and transported all uranium ore to milling operations in Utah. The company is therefore no longer seeking to renew its air quality permit for that location. Permanent closure of the Pinenut mine is a long-term process and will require working with multiple agencies. (Arizona Daily Sun Apr. 15, 2016)
Renewal process for air-pollution permit of three Grand Canyon mines suspended, as fourfold increased uranium level found in soil near Pinenut mine:
State environmental officials have suspended the air-pollution permit renewal process for three uranium mines near the Grand Canyon. Recent tests showed uranium content in the soil near one of the mines is four times higher than previously measured. Arizona Public Radio's Ryan Heinsius reports.
The tests were conducted in July and October outside the perimeter of the Pinenut Mine facility. The analysis showed uranium in the soil at one out of the five testing sites had spiked since 2011 when the mine reopened.
The Arizona Department of Environmental Quality says the elevated level of the radioactive metal doesn't present an immediate public health risk. But the agency has pushed the mines' owner, Energy Fuels Resources, to boost measures to control radioactive dust. ADEQ has also mandated that the company expand soil testing in the area.
ADEQ is considering the renewal of air-pollution permits for all three mines, but will suspend that process as it evaluates the company's new dust-control plan at the Pinenut Mine. The agency will eventually open a new public comment period and hold meetings for the permit renewals. (KNAU Arizona Public Radio Dec. 30, 2015)

Conservation groups urge BLM to suspend Pinenut uranium mine in response to groundwater contamination:
Conservation groups have sent a letter urging federal regulators to suspend operations at a uranium mine near the Grand Canyon, where millions of gallons of uranium-laced groundwater threaten people and wildlife. Records from the U.S. Geological Survey show that the contaminated groundwater -- 80 times the limit set to protect public health and the environment -- have inundated the Pinenut uranium mine immediately north of Grand Canyon National Park. It is unknown whether deep aquifers and nearby springs in the national park are also being polluted.

Pinenut uranium mine to continue operation into 2015: On Apr. 23, 2014, Energy Fuels announced that it has revised its previous guidance and currently expects to continue mining at its 100% owned Pinenut Mine through 2014 and into the 1st quarter of 2015.
Pinenut mine to be placed on care and maintenance due to market conditions: Mining at the Pinenut mine is expected to continue into the middle of FY-2014 (July 2014), at which point the mine is expected to be placed on care and maintenance. Re-starting mining activities at Pinenut would be evaluated in the context of business and market conditions, including the U3O8 price environment. (Energy Fuels Inc. Nov. 14, 2013)
Energy Fuels Incorporated proposes to open the Pinenut Mine in Mohave County late this month or in early June, according to a statement from the Bureau of Land Management. (Arizona Daily Sun May 9, 2013)

Geologist raises concern over potential groundwater contamination at Crow Butte uranium ISL mine: Hannan LaGarry, a Chadron State geology instructor, said the Crow Butte mine has ignored recent studies that show faults and fractures in underground layers of rock that could carry contaminants to aquifers used for drinking and livestock. LaGarry said he's not opposed to uranium mining but is concerned that the mine is relying on outdated studies of underground rock. "In recent years, we've found that the assumptions made by previous workers were false and that newer detailed work shows a different story," he said. (Omaha World-Herald Dec. 14, 2008)

On Aug. 11, 2011, the Nebraska Department of Environmental Quality issued the permit for the construction and operation of the North Trend Expansion Area of the Crow Butte uranium in situ leach mine.
Opposition to aquifer exemption for North Trend expansion of Crow Butte uranium in situ leach mine:
Uncertainties regarding the presence of faults and factures in the land underlying northwest Nebraska are a major reason that the Crow Butte Resources uranium mine should not receive an 'aquifer exemption' for its proposed North Trend expansion project, opponents of the mine said Monday (Aug. 23).
Making a decision now to allow use of the estimated 1.85 billion gallons [7 million cubic metres] of water in the lower portions of the Chadron formation under the expansion area would be premature, countered David Frankel, an attorney representing mine opponents in hearings before the Nuclear Regulatory Commission. Detailed research by Chadron geologist Hannan LaGarry indicates that faults and fractures common in the area could link the Chadron aquifer to other water bearing layers, including the Brule and Arikaree, which are used for drinking water, he said. (Rapid City Journal Aug. 25, 2010)
The Nebraska Department of Environmental Quality has scheduled a public hearing regarding a proposal to exempt a portion of the Chadron Aquifer north of Crawford. This portion of the aquifer is associated with a proposed expansion area for the Crow Butte Resources (CBR) uranium mining facility. The proposed exemption would prevent that designated area of the aquifer from being used as a drinking water source in the future.
The public hearing is scheduled for Monday, August 23, 2010.

The ownership of the Crow Butte Resources uranium mine near Crawford by a Canadian mining company is a legitimate issue for argument in deciding whether the mine should be allowed to expand its operation to a nearby site, a three-member panel of Nuclear Regulatory Commission judges has ruled.
In a decision issued Jan. 27, 2009, the NRC judges also said that questions of the impact of low levels of arsenic in water returned to aquifers during mining operations, the relationship between arsenic exposure and diabetes and information about an alleged cluster of pancreatic cancer in the Chadron area can also be raised during hearings on the mine's proposed North Trend expansion.

Environmental groups fight against state permit for reactivation of Mt. Taylor uranium mine:
Environmentalists are seeking to keep an idle uranium mine in western New Mexico from becoming active again, saying the designation will allow it to delay cleanup.
The Multicultural Alliance for a Safe Environment and Amigos Bravos are asking the New Mexico Mining Commission to review a recent decision by state Mining and Minerals Division Director Fernando Martinez to allow the Mount Taylor mine to return to "active," or operational, status, the Gallup Independent reports.
The groups say there is no realistic likelihood that mining will take place for the foreseeable future. "The director's decision directly contradicts the New Mexico Mining Act's plain language, which restricts 'operational' mines to those that are producing minerals," said Eric Jantz, staff attorney at the New Mexico Environmental Law Center, which is representing the groups. "The director has unilaterally created an entirely new category of mine activity - 'zombie mines' - that have been given new life in an effort to avoid cleanup."
The Mount Taylor Mine has been on standby status for more than 20 years. Its owner, Rio Grande Resources, announced in 2014 that it planned to ask regulators to change the status to active. (Albuquerque Journal Mar. 19, 2018)
State issues permit for reactivation of Mt. Taylor uranium mine: On Nov. 22, 2017, Rio Grande Resources notified NRC that the New Mexico Environment Department (NMED) issued a mine active permit the same day, and that the company plans to submit the application for a uranium mill in the fourth quarter of 2022.

Court orders new hearing in Mt. Taylor uranium mine permit:
In a hearing this morning, state District Court Judge Raymond Ortiz handed a victory to community groups in a case concerning Rio Grande Resources' Mount Taylor uranium mine near Grants. In a ruling from the bench, he agreed that the New Mexico Mining and Minerals Division (MMD) failed to provide the public with meaningful opportunities to participate in the process to renew the mine’s standby mining permit.
He focused on three issues:
Group seeks public hearing over proposed reactivation of Mt. Taylor uranium mine after 23 years of inactivity: Today, the New Mexico Environmental Law Center (NMELC) filed a request for a public hearing regarding a proposed permit revision to put the Mt. Taylor uranium mine on active status. The mine, near Grants, NM, has been inactive (on "standby" status) without cleanup for 23 years. The mine's owner, Rio Grande Resources, received a fourth renewal for the standby permit in January 2012, but on April 12, 2013 it notified the public it was seeking a revision to change the mine's status to "active". The NMELC filed the hearing request on behalf of its clients, Amigos Bravos and the Multicultural Alliance for a Safe Environment (MASE). (NMELC May 10, 2013)
Mine agency to take input on renewal of standby permit requested for Mount Taylor uranium mine:
The New Mexico Mining and Minerals Division has set a public hearing for Rio Grande Resources Corporation's application to renew "Standby Status" for its Mount Taylor Mine on Wednesday, Aug. 17, at 5 p.m. in the Cibola County Convention Center.
A standby permit allows the mine operator to let the mine remain inactive without having to do any clean up. The permit lasts for five years. The Mount Taylor mine is located one mile northeast of San Mateo. The mine is an existing underground uranium mine that extracted uranium ore from depths of more than 3,000 feet below ground surface using room-and-pillar and stope mining methods. Uranium ore was produced from the mine from 1979 to 1982 and from 1985 to 1990. The mine has been inactive since January 1990. A copy of Rio Grande Resources' application for the renewal of Standby Status is available at the Mother Whiteside Memorial Library and in Santa Fe at the Mining and Minerals Division's office. These documents are also available for viewing on the MMD website . (Cibola Beacon Aug. 15, 2011)
Rio Grande Resources Corporation (RGR) submitted a Standby Status Renewal Application for its Mt. Taylor Mine.
The mine is an existing uranium mining operation using underground mining techniques to extract uranium ore from depths of over 3000 feet below ground surface using room-and-pillar and stope mining methods. There are no milling facilities within the proposed Standby area.
The Mine has been inactive since January 1990 until the present.

A groundwater discharge permit is being sought for Mount Taylor Uranium Mine and Mill owned by Rio Grande Resources, according to the New Mexico Environment Department .
Gerald Schoeppner of NMED's Groundwater Quality Bureau said Wednesday that the company has an existing discharge plan for its mine that it's trying to renew, "but that's one of the pieces of the puzzle that's missing - how they're planning to treat their mine water for the dewatering to meet standards."
The Mount Taylor mine previously was a conventional mining operation "and they plan to operate it as a conventional mine in the future," Schoeppner said. The mine site is located just outside the 8,000 foot elevation boundary established in the June 2008 emergency designation of Mount Taylor as a Traditional Cultural Property.
Rio Grande Resources controls uranium operations and mineral resources acquired by General Atomics from Chevron Resources in 1991. The Mount Taylor project, a conventional underground mine, contains the largest uranium resource in the United States and is currently on standby, according to the company's Web site. Chevron began commercial production at Mount Taylor in 1986, initially shipping the ore to its Panna Maria mill in south Texas for processing. The mine was placed on standby in 1989.

"[...] The bleed at PA-3 [production area three] did not contain the increased pressures caused by injection of leaching fluids. A hydraulic gradient was rapidly established between the injection wells and the mine boundary, as shown by a rise in water levels in monitor wells surrounding PA-3. This gradient drove mining solution beyond the mine boundary. These excursions affected a well on the Garcia property, approximately 300 m down gradient of the mine. Since mining began, uranium concentrations in the Garcia well have increased from less than 200 µg/L, to more than 600 µg/L.
This is the first time that contaminants in an off-site domestic well have been linked to ISL uranium mining in the United States of America."

Mine Safety and Health Administration settles with Reliance Resources on penalties for fatal accident at Pandora mine in 2010: Mine Safety and Health Administration (MSHA) has settled with Moab based Reliance Resources LLC for penalties associated with the fatal mine accident at the Pandora Mine on May 26, 2010. Reliance Resources operated the mine in La Sal, Utah, for Denison Mines Corporation, a Canadian company. Hunter Diehl was killed when large rock fell on him. He was manually scaling loose material from the rib when it fell.
Pandora mine to be shut down: On Oct. 17, 2012, Energy Fuels Inc. announced that it will cease mining at the Pandora property during the second quarter of FY 2013, pending the depletion of its identified uranium and vanadium resources.
Pandora mine operator fined $92,600 for fatal accident: The Mine Safety and Health Administration (MSHA) has issued a penalty of $92,600 to Reliance Resources, LLC, for two violations from the fatal accident on May 26, 2010, at the Pandora Mine (Mine ID 4200470), La Sal, San Juan County, Utah. (UraniumWatch May 7, 2011)
More worker health and safety violations at La Sal mines:
The January 2011 Mine Safety and Health Administration (MSHA) inspections resulted in 5 worker health and safety violations at the Pandora Mine for Reliance Resources LLC and 6 violations at the Beaver Shaft for Denison Mines (USA) Corp. All MSHA violations were associated with the failure of the mine operators to properly protect the workers from exposure to radon daughters (short lived, highly radioactive particulates from the decay of radon) in the mines.
Both Denison Mines and Reliance Resources were cited for exposure of workers to air with concentrations of radon daughters exceeding 1.0 working level (WL) in active workings and for the failure of workers to wear respirators in areas where the radon daughters exceed 1.0 WL. Reliance Resources was also cited for improper ventilation, not posting inactive workings where radon daughter concentrations are about 1.0 WL, and failure to calculate and record complete individual exposures in active working areas with radon daughter concentrations are more than .03 WL. This followed an inspection of December 20 when Denison was fined $6,000 for exposure of workers to radon daughters above the acceptable level, improper ventilation, and failure to calculate and document worker exposure to radon daughters, or progeny.
At the beginning of December, Denison was citied for 12 other violations, some for the same violations that Reliance Resources was cited for after Hunter Diehl was killed at the Pandora Mine 2010. Denison failed to correct hazardous conditions associated with scaling and support and failed to have a competent person examine each working place at least once each shift for conditions that may adversely affect safety or health.
In 2009 Denison received 13 citations; Reliance Resources received 14; total penalties for all were $3,629. In 2010, Denison received 34 citations and orders; total penalties of $18,304. Reliance Resources received 18 citations and orders; total penalties of $2,664 (this does not include any penalties associated with the fatal Pandora Mine accident on May 26, 2010).
Denison has been ajusting its ventilation system to reduce radon emissions so that they do not exceed the standard for doses to the nearest residents, La Sal School, and road maintenance shed. It is difficult for Denison to meet both the dose standard for off-site exposures to radon and the underground worker exposure standards.

Judge approves drilling at Pandora uranium mine in Manti-La Sal National Forest: A federal judge will allow a uranium mining company to drill several new holes in the Manti-La Sal National Forest. Three Moab conservation groups had asked Judge Dale A. Kimball to halt the drilling planned by Denison Mines Corp. at its Pandora Mine, claiming the U.S. Forest Service permitted the project without an adequate environmental study. Uranium Watch, Center for Water Advocacy and Living Rivers argued that Denison would create radioactive air emissions and heavy metal contamination if it drills 16 exploration holes and two radon vent holes, a project approved by the Forest Service. Kimball gave more weight to Denison's environmental expert, who said there was no significant risk of environmental harm. Kimball also wrote that the Forest Service followed procedural rules when it allowed the project without environmental assessments or impact statements. (Salt Lake Tribune Sep 14, 2010)
Groups file suit to stop expansion of Pandora uranium mine in La Sal, Utah:
Uranium Watch, Center for Water Advocacy, and Living Rivers, conservation groups located in Moab, Utah, yesterday (July 29) filed suit in federal district court in Salt Lake City to halt uranium exploration and the construction of radon vent holes on U.S. Forest Service land in the Manti-La Sal National Forest in La Sal, Utah.
The complaint filed with the United States District Court for the District of Utah challenges a decision by the Moab/Monticello Ranger District to permit the drilling of 16 exploration drill holes and 2 radon vent holes as part of the expansion of the Pandora Uranium Mine.
Radon is vented to the surface from the underground mine operations so that the miners will not breath in the radon gas and be exposed to the short-lived highly radioactive particles that are produced when radon decays. The proposed radon vents would add to the amount of radon gas and radioactive particulates released in the vicinity of the community of La Sal, on the south slope of the La Sal Mountains. In 2009, the amount of radon released from the uranium mines in La Sal jumped from 300 Curies to over 4,500 Curies, according to Denison's annual reports to the Utah Division of Air Quality. Radon is released from vents near the Beaver Shaft not far from the La Sal Elementary School. (Uranium Watch, July 30, 2010)
Uranium miner dies in rockfall accident in Pandora mine:
A 28-year-old uranium miner from Moab died Wednesday (May 26) morning after he was hit by falling rock in the Pandora mine near LaSal, San Juan County.
(The Salt Lake Tribune May 26, 2010)
Federal regulators faulted a Utah company for safety lapses in the death of a uranium miner who was killed by a large rock slab he was peeling off a tunnel wall near La Sal. A Mine Safety and Health Administration report released Thursday (Sep. 23) said Reliance Resources LLC of Moab was cited for inadequate worker training and failing to test a tunnel wall for loose rock. The citations were rescinded after the company took corrective measures. The report says 28-year-old Hunter Diehl ("deal") of Moab was using a pry bar to pull off loose slabs May 26 when one fell on top of him. He was pronounced dead later at a hospital.
