Protest march against White Mesa uranium mill
About 80 protesters opposed to the White Mesa uranium mill in southeast Utah marched three miles along U.S. Highway 191 to the mill's entrance Saturday (May 13).
The protest was organized by members of Ute Mountain Ute tribe, which has a small reservation community three miles from the mill. The mill, which is owned by Energy Fuels, of Toronto, is the only conventional uranium mill operating in the country.
Protesters carried anti-nuclear signs, including "No Uranium, Protect Sacred Lands," "Water is Life," and "No Toxic Waste."
They are concerned about the mill's potential health impacts on air and water quality, and they object to containment cells at the mill that accept radioactive waste from around the country.
Several environmental groups also attended the rally, including Grand Canyon Trust, which sued Energy Fuels in 2015 for allegedly operating too many waste containment cells than allowed for under Environmental Protection Agency regulations. The case is pending.

Leakage from White Mesa uranium mill's tailings impoundments threatens water, Ute tribe
The Ute Mountain Ute Tribe and environmental organizations worry that the White Mesa Uranium Mill, the nation's last conventional uranium mill, threatens the water quality of vital springs and poses a long-term threat to the Navajo Aquifer, the main source of drinking water for southeastern Utah and northern Arizona. These concerns are highlighted in the new film, "Half Life" [12 min], released today.
The mill processes both uranium ore and alternate feed (uranium-bearing radioactive waste) from across North America. The radioactive and toxic waste that remains after processing is disposed of in open pits called "impoundments" that take up about 275 acres [1.1 km2] next to the mill. The older impoundments at the mill are lined with thin layers of PVC, and the RRD International Corp, a team of mining experts, has concluded that these liners had a useful life of 20 years when installed in the early 1980s. The older liners also lack modern leak detection systems that would prevent groundwater contamination.
To date, no contamination has reached the four springs regularly monitored by the tribe, but evidence of growing plumes of contaminants in the perched aquifer below the mill site continues to mount.

Data shows need to continue radon monitoring at White Mesa uranium mill
"In July 2014, the Utah Division Radiation Control (DRC) ordered Energy Fuels Resources (USA) Inc. to monitor the radon emissions from Cell 2 twice yearly and report them in the White Mesa Mill Semi-Annual Effluent Monitoring Report (SAER). The SAER for the Second Half of 2014 includes the results of Cell 2 radon monitoring.
Energy Fuels conducted 2 monitoring events, in July and September. The July test shows a flux of 20.4 pico Curies per square meter per second (20.4 pCi/m2-sec). This is above the 20 pCi/m2-sec limit the DRC established for Cell 2. The DRC determined that Cell 2 was in "closure," so no longer subject to the Environmental Protection Agency 20 pCi/m2-sec standard, so the DRC adopted that standard for Cell 2. In August Energy Fuels added additional materials on the interim cover to reduce the radon emissions, then retested in September. The September radon flux was below the emission limit. This shows that the DRC must require the continued monitoring of the Cell 2 radon emissions during closure.
The mill continues to emit high levels of radon from the radium-laden effluents in Cells 1, 3, 4A, and 4B. The average emissions from Cells 1, 4A, and 4B (~ 135 acres) for 2014 was 1,749 pCi/m2-sec, up from 156 pCi/m2-sec in 2013."

Dramatic increase of radium concentrations in White Mesa uranium mill tailings impoundments suggests radon emissions way beyond standards
The 2014 Annual Tailings Wastewater Monitoring Report shows a dramatic increase in the Cells 1, 4A, and 4B radium content. The data in the Report was based on August 2014 sampling events. As shown in the Table , based on the Environmental Protection Agency (EPA) formula for determining radon emissions from the White Mesa Mill liquid impoundments, the radon emissions from Cells 1, 4A, and 4B, have increased dramatically and average ~1,700 pCi/m2-sec (pico Curies per square meter per second), when the standard for older tailings impoundments is 20 pCi/m2-sec.
The 2014 Annual Wastewater Monitoring Report provided the following information regarding the reasons for the increase in gross radium alpha:
These conditions will continue, as Energy Fuels Resources (USA) Inc. has announced that they will put the Mill on standby in early 2015. Therefore, there will continue to be high levels of radon emissions from the solutions in these 4 impoundments. Yet, the EPA and Utah Division of Air Quality (DAQ) have done nothing to address this situation. In fact, the EPA maintains that radon emissions from liquid impoundments are ZERO.
(UraniumWatch Jan. 15, 2015)
- During June, July, and August operating period fresh water was not added to the Mill process. Re-circulated tailings liquids were used for process water. Re-circulated fluids were then returned to the tailings system or evaporation ponds.
- From August 2013 to August 2014, the Mill's production was limited, resulting in less fresh water added to the Mill process and therefore to the cells. The decrease in the addition of fresh water resulted in concentration of existing fluids.
- Drought conditions resulted in less precipitation, therefore, less rainwater and storm water going into the cells. Drought also caused higher evaporation rates.

Data shows unacceptably high levels of radon emissions at White Mesa uranium mill
Recent data shows high levels of radon emissions from processing effluents and other ponded liquids at the White Mesa Mill. The fluids are held in lined impoundments or in ponds on top of solid tailings. The liquids come from the uranium ore processing, dewatering of Cell 2, pumping of contaminated groundwater, and surface runoff.
For years the Environmental Protection Agency (EPA) claimed that these radium-laden liquids did not have to be monitored because the radon emissions were “zero.” Now, putting together an EPA formula that determined that for every 1,000 pico Curies per liter (pCi/l) of radium in the effluents at White Mesa, there were 7 pico Curies per meter squared per second (7 pCi/m2-sec) of radon emissions. Recent Energy Fuels Resources Inc. data on the radium content of the liquids shows that the radon emissions are far greater than the 20 pCi/m2-sec emission standard for the dry tailings in the older (“existing”) impoundments. The emissions from liquid tailings range from 102 to 573 pCi/m2-sec, which is 5 to 28 times the radon emission standard for solid tailings.

WHITE MESA - During an intense community meeting here, environmental groups and the Ute Mountain Tribe warned residents of health dangers if the EPA changes rules governing a nearby uranium mill.
Representatives from Grand Canyon Trust , Information Network for Responsible Mining , Uranium Watch and the tribe are urging the public to oppose removing national radon emission and waste-storage standards affecting the nearby White Mesa Uranium Mill, owned by Energy Fuels.
"Not knowing what the radon emissions are from the mill is a serious risk to public health in Blanding, White Mesa and Bluff," said Anne Mariah Tapp, an attorney for Grand Canyon Trust.
Tapp is concerned that radioactive toxins are released from six impoundments that store wastes from milling uranium ore into yellow cake. The concentrated uranium product is packed in barrels and shipped to make fuel rods for nuclear power plants.
Uranium mill critics are urging the EPA to not remove the 20 pico Curie radon emission standard for impoundments. Radon is a radioactive by-product of the uranium milling process.
Another concern is an EPA proposal to do away with a requirement that only two tailing impoundments can operate at a time, Tapp said.

Group files challenge to Division of Radiation Control order affecting radon emissions from tailings of White Mesa uranium mill
Uranium Watch is challenging the Utah Div. of Radiation Control (DRC) July 23, 2014, Order regarding the closure of tailings Cell 2. The DRC ordered Energy Fuels Resources Inc. (EFRI) to cease placement of tailings and other waste in Cell 2. The DRC ordered EFRI to monitor the radon emissions twice a year and demonstrate compliance with the 20 pCi/m2-sec [0.74 Bq/m2-sec] radon emission standard until EFRI recalculates the dose to the nearest member of the public talking into consideration higher radon emissions from Cell 2. Based on the Order, Cell 2 would no longer fall under the Environmental Protection Agency standard for uranium tailings impoundments that were constructed before December 1989 (40 C.F.R. Subpart W, § 61.252(a)).
Uranium Watch's August 22, 2014, Request for Agency Action questioned the cessation of radon monitoring for Cell 2 as the impoundment continues to dry out. Uranium Watch questioned DRC's claim that Cell 2 is now in closure, yet there is no approved reclamation plan and no reclamation milestones in the White Mesa license, as required by both EPA and DRC regulation.

Grand Canyon Trust issues legal notice to Energy Fuels over environmental issues with tailings at White Mesa mill
Ongoing violations of the Clean Air Act at the nation's only operating uranium mill have prompted Grand Canyon Trust to file a 60-day notice of intent to sue Energy Fuels Resources, the owner of the White Mesa Mill, located near White Mesa and Blanding, Utah.
In the notice Grand Canyon Trust cites data showing that in 2012 and 2013 the annual average radon-222 emissions at the mill exceeded hazardous air pollutant standards. It further alleges that, during that same time period, mill owners operated six tailings impoundments when only two are allowed, and that two of those are larger than the maximum allowed size of 40 acres.

White Mesa mill to be mothballed due to market conditions
Energy Fuels Inc. plans to fulfill its delivery contracts with stockpiled uranium and uranium purchased on the spot market, allowing it to discontinue current U3O8 production at the White Mesa Mill beginning in August 2014 until the latter half of 2015, at which time the mill is expected to re-commence processing alternate feed materials. The current spot price is lower than the company's production cost.

Radon emission exceeds standard at Tailings Cell 2 of White Mesa mill
The 2012 Annual Compliance Report for the emission of radon from the White Mesa Mill tailings impoundments reported that the radon flux for the 66-acre [27 ha] Cell 2 exceeded the standard in 2012. The Cell 2 emission of radon is 1.59 times the 20 pico Curie per square meter per second (pCi/m2/sec) [0.74 Bq/m2/sec] requirement for a tailings impoundment that exceeds 40 acres. Energy Fuels Resources Inc. (EFR) concluded that the increase in radon-222 flux from Cell 2 was caused by dewatering, and was unavoidable. In 2011 and 2012 EFR adopted an acclelerated dewatering program, based on the Ground Water Discharge Permit requirements. Cell 2 must also be dewatered to settle the tailings before the placement of the final radon barrier. The mill is required to have reclamation milestones for the placement of the interim cover, dewatering, and placement of the final radon barrier, but does not.
Due to the exceedance from Cell 2, EFR will be required to measure and report the radon flux on a monthly basis, starting April 2013.
The radon emissions will continue to increase during the dewatering process, which will take several years. EFR estimates that the radon emission levels will reach equilibrium, due to the depth of the tailings. Placement of additional fill will reduce the radon emissions. EFR estimates that the addition 1 foot to the interim cover reduce the average flux to within the standard, based on the estimated flux over the next year. EFR has proposed test plots with 1 foot of fill to determine if it will bring the emissions below the standard. If the tests are successful, the propose to add 1 foot of fill to the existing cover, to be completed by mid-2014.
They suggest this, even though they estimate that it will take 2 feet of fill to to reduce surface radon flux to below 20 pCi/m2/sec, regardless of the depth of dewatered tails.

New study finds mild contamination outside White Mesa uranium mill
A new government study has found radioactive contamination just off-site from a controversial uranium mill. But it may not be serious enough to bolster the arguments of the plant's critics.
White Mesa is the nation's only active uranium mill and is currently undergoing relicensing by the state. The Ute Mountain Ute Tribe asked for an independent federal study, apparently because they didn't trust the company or state regulators.
The closest homes are more than a mile away, and those neighbors showed only a mild concern about the mill.
There's no cause for undue alarm, said David Naftz with the U.S. Geological Survey , because there are no people or drinking water sources near the area.
The Ute Tribe has battled the plant for years, insisting it poses a serious health threat on the reservation three miles away. In the latest study, federal scientists sampled dirt, sagebrush and springs. They found some radioactive hits just outside the plant boundary, the chemical fingerprints of uranium ore.
"And all of those fingerprints were high," Naftz said. He says it's probably windblown dust from trucks or the plant site itself.
"It looks like it's coming from uncovered ore storage pads, where they store the ore before it's processed at the mill site," he said.
If some of that contamination came from uncovered trucks, then that part of the problem has be resolved.
"In fact, BLM and the Utah Department of Transportation actually issued a memorandum about three years ago requiring these ore trucks to transport their materials covered," Naftz said.
But the contamination is mild and reaches, at most, a third of a mile from the site and preventing more contamination shouldn't be too hard, according to Naftz.
Naftz said covering the pads, or a more cost-effective remediation might be to install sprinkler systems to wet it down.
The federal scientists recommended drilling more monitoring wells as an early warning system in case there is groundwater contamination. The report also recommended periodic monitoring in areas where the study turned up evidence of off-site migration. It also recommended sampling of sagebrush by the company every three years.

White Mesa mill halts processing of uranium ores
Denison Mines President Ron Hochstein said that Denison's White Mesa Mill, the nation's only operating uranium mill, has ceased its regular milling operations for the remainder of 2009.
"We will stop processing conventional ore through 2009, but will be processing alternate feedstock on a reduced scale, and we'll be laying off some personnel," said Hochstein. "Our costs are higher than the current spot price."

Denison exceeds number of permitted truckloads hauling uranium ore from San Miguel County (Colorado) to White Mesa mill (Utah)
Denison Mines Corporation still has the only operating uranium mill in the country, and it is still pulling ore from just one place: San Miguel County. And according to San Miguel County officials, the company is hauling more than they agreed to in their permit.
Mike Rozycki, the county planner, said that the uranium company has exceeded the maximum number of 12 truckloads of ore per day outlined in their permit. Rozycki said that there had been a "misunderstanding," and that the company believed that the maximum number was an average, and that days with less traffic allowed them to haul more at other times.
"We put them on notice that we thought there was a violation," said Rozycki. "We had issues and concerns, and we will have a public hearing when they submit their amendment to the permit."

Conventional ore processing commences at White Mesa Mill
On Apr. 29, 2008 Denison announced that processing of conventional ore at its White Mesa mill in Utah began on Monday April 28th, 2008.
Over the next 30 to 45 days, the mill will be processing uranium-only ore from the Tony M operation and will then switch to the uranium/vanadium ores from the company's Colorado Plateau mines. Currently, there are approximately 150,000 tons of ore from the various Company owned mines on the stockpile at the mill.
Denison is projecting production of between 1.4 and 1.7 million pounds of U3O8 (538 - 654 t U) and 3.0 to 4.0 million pounds of vanadium pentoxide from White Mesa in 2008.
IUC announces reopening of uranium mines
On June 14, 2006, International Uranium Corp. announced the re-opening of its U.S. uranium/vanadium mines. Mining activity will commence immediately and mined ore will be stockpiled at the Company's wholly-owned White Mesa uranium/vanadium mill in southeastern Utah.
The properties are in three distinct mining districts:
Based on current mine production schedules, processing of the ore would begin late fourth quarter 2007 or first quarter 2008, depending upon securing additional alternate feed material and third party ore. In the initial year, IUC anticipates producing approximately 3.4 million pounds of U3O8 [1308 t U] and 5.9 million pounds of vanadium, thereafter, averaging between 1.5 and 2 million pounds per year of U3O8 and vanadium.
(IUC June 14, 2006)
- Colorado Plateau: IUC intends to immediately commence mining activities at the Pandora, Topaz, Sunday and St. Jude mines. This will be followed by two additional mines in the Colorado Plateau region in early 2007. All of IUC's mines on the Colorado Plateau are fully permitted.
- Henry Mountains area: plans are to complete the permitting on the Tony M mine with production slated for late spring 2007. Development of the Bullfrog property will begin in the spring of 2007 and production is projected to begin mid-year 2008.
- Arizona Strip district: IUC will also review and revise the engineering estimates for the fully permitted Arizona 1 Mine with development scheduled to begin early 2007 and production beginning in late summer 2007.
Leaking barrels with alternate feed material originating from Honeywell Metropolis conversion plant arrive at White Mesa mill
"On January 12, 2017, at approximately 1142 MST, a TAM International van carrying barrels of KOH alternate feed materials from Honeywell International arrived at the White Mesa Mill Scale house. According to Honeywell the materials are basically uranium ore concentrates. The White Mesa employees began unloading the van, but as they began offloading some of the last barrels, they noticed that some of the barrels were leaking. From what they could tell, three barrels were potentially leaking. The barrels were not rusted through, but were 'soft' and allowed liquid contained in the solid materials to leak from the barrel. The material leaked from the barrel onto a plastic sheet; however, the plastic sheet had an opening (rip, tear) through which the material was able to pass. [...] it is likely that only small quantities of materials were leaking from the van.[...]
At the last verification, the Honeywell KOH material contained, approximately 633,000 mg/kg uranium (about 61% uranium), 39 pCi/g Pb-210, 44.6 pCi/g Ra-226, 358 pCi/g Th-230, and 27 pCi/g Th-232."

On Sep. 8, 2006, the Utah Radiation Control Board cleared the way for the Glen Canyon Chapter of the Sierra Club to challenge the "alternate feed" rule that allows the International Uranium Corp. mill to recycle material from FMRI Inc., in Muskogee, Okla.
Sarah M. Fields of the Sierra Club has said the Oklahoma material is not "alternate feed." It contains high radium concentrations - as much as 85 times the concentrations federal and state laws allow - so International Uranium should be regulated like a radioactive waste disposal site, she said.
The material also contains large quantities of highly toxic contaminants - including cyanide, lead and tin - that require the site to be regulated as a hazardous waste facility, she said.

The Utah Department of Environmental Quality is Soliciting Comments on a Proposed Amendment to International Uranium (USA) Corporation's Radioactive Materials License UT1900479 to Allow Acceptance and Processing of an Alternate Feedstock Material. The IUSA submitted a License amendment application to amend its State License to receive and process alternate feed material from Fansteel’s FMRI facility located near Muskogee, Oklahoma (the "Muskogee Facility"). The proposed amendment would allow IUSA to receive and process up to 32,000 short tons of alternate feed material from the Muskogee Facility for its uranium content. The FMRI alternate feed materials are residues resulting from ore processing for the extraction of tantalum and niobium, i.e. byproducts of FMRI processing operations.

IUC forms joint venture with NFS to recycle DOE's contaminated low enriched uranium
"International Uranium Corporation
(the "Company") is pleased to announce that it has formed a 50/50
joint venture company, "Urizon Recovery Systems, LLC", with
Nuclear Fuel Services, Inc. ("NFS") to pursue the development of
a new, long-term, alternate feed program (the "USM Ore(TM)
Program") for the Company's White Mesa Mill that, if successful,
is expected to result in the Mill producing two to three million
pounds of yellowcake [containing 769 to 1154 metric tonnes U] per year over at least a six-year period. [...]
The USM Ore(TM) Program that Urizon is pursuing involves the
development of a process and construction of a plant at NFS' facility in Erwin, Tennessee, for the blending of contaminated
low enriched uranium with depleted uranium to produce a natural
uranium ore ("USM Ore(TM)"). The USM Ore(TM) will then be further
processed at the Company's White Mesa Mill to produce
The primary source of feed for Urizon will be the significant
quantities of contaminated materials within the DOE complex. [...]"
(IUC Nov. 14, 2002)
However, on Jan. 29, 2004, IUC announced that DOE had refused Urizon's request to fund the design costs of the USM Ore(TM) processing facility.
Alternate feed processing run at White Mesa Mill underway
The White Mesa Mill has begun processing the Ashland 1 FUSRAP (Formerly Utilized Site Remedial Action Program) material. As of mid August 2002, the Mill had processed over 40,000 tons of material. Currently the Mill has additional stockpiles of over 200,000 tons of Ashland 1 and Linde material, which will be processed during this mill run.
In addition, IUC has a contract with Molycorp, Inc. for receipt and processing of approximately 10,000 tons of uranium-bearing material. This material may begin arriving at the Mill in mid-September 2002, pending resolution of a regulatory hearing. (IUC Aug. 29, 2002)
EPA expresses concerns about expansion of alternate feed business
In a letter to NRC dated Jan. 16, 2002, the U.S. Environmental Protection Agency expresses concerns about the proposed expansion of the processing of alternate feed at uranium mills and calls for a thorough review:
"[...] Mill tailings impoundments were designed to serve as a long-term control measure for radon and other hazardous emissions from source material extraction wastes, and to prevent radiation exposures resulting from inadvertent uses of these wastes by members of the public. It appears that these impoundments are being suggested by the petitioner to serve in a different capacity than for which they were designed and approved. Additional uses as a long-term repository (disposal) for a wide variety and volume of low-level, mixed, and hazardous wastes require appropriate consideration. Such consideration would include a formal review of the new uses for these facilities under the National Environmental Policy Act and possibly licensing and authorization under other relevant environmental statutes. To the extent that some of these suggested wastes might not be regulated under the Uranium Mill Tailings Radiation Control Act (e.g., pre-1978 mill tailings), other environmental authorities might still apply.
> Download EPA comment (1215k PDF)
Such a review may very well conclude that these additional new wastes have no significant impact on the impoundment designs and that environmental authorities are satisfied. However, suggested uses such as 'new alternatives to current disposal options' for large volumes of low-level radioactive waste, and other wastes, deserve a thorough review to ensure the uranium recovery facilities continue to be protective, and the public is aware of the proposed change in the use of these facilities.

IUC requests license amendment to process material from Maywood FUSRAP Site, NJ
By letter dated June 15, 2001, IUC requests a license amendment for processing of up to 600,000 cubic yards (840,000 short tons) of Uranium Material from the Maywood FUSRAP site in New Jersey. The Uranium Material at this site originated from uranium and thorium-bearing monazite sands. Its uranium content ranges from non-detectable to approximately 0.06 weight percent uranium (0.072 weight percent U308), or greater, with an estimated average grade of 0.0018 percent uranium (0.0022 weight percent U308) for the entire Maywood Site. However, IUC intends to accept Uranium Material for processing at the Mill only if a cut-off level of 0.01 weight percent uranium is satisfied (IUC letter Aug.3, 2001).

Walk Against Nuclear Waste
Citizens and environmental groups in southern Utah held a "Walk Against Nuclear Waste" in the last week of May 2001. More than 40 individuals walked simultaneously from Blanding (San Juan County) to Moab. The eighty-mile walk, led by longtime San Juan County activist Ken Sleight, followed U.S. Highway 191. Cosponsoring groups included Moab-based Living Rivers, Glen Canyon Action Network, and the Sierra Club Glen Canyon Group, as well as HEAL-UTAH from Salt Lake City. The groups opposed IUCs recent application to process radioactive lead waste from a site in California. They fear the White Mesa site will end up in similar mess as the Atlas Moab uranium mill tailings site. The groups demanded the closure of the mill and the cleanup of the mill site.

Tailings capacity at White Mesa mill insufficient for proposed processing of more alternate feed
At the request of NRC, IUC had to admit that the currently available tailings capacity at its White Mesa mill is not sufficient for the requested processing of more alternate feed material.
The currently licensed activities would result in 1,150,550 tons of tailings, while the current capacity is 1,174,000 tons, leaving 23,450 tons of remaining capacity. The requested processing of the W.R. Grace material would add 108,000 tons, and potential alternate feed material from other sources (i.e. Linde, Molycorp and Heritage Minerals) would add another 146,200 tons.

USACE agrees to request State approval before sending further material for alternate feed processing at White Mesa mill
The Army Corps of Engineers has now agreed to not send additional shipments of radioactive mill tailings to the White Mesa uranium mill near Blanding without prior approval of the State of Utah. The agreement, however, does not extend to the Army Corp's current contract with International Uranium Corp., the owners of the White Mesa mill, to reprocess thousands of tons of radioactive soils from the FUSRAP site in Tonawanda, New York. (Deseret News, April 25, 2000)
Questions raised about quality of alternate feed material from Tonawanda FUSRAP site
"Meanwhile, the Environmental Protection Agency has launched a criminal investigation into early disposal efforts in Tonawanda, probing whether the contractors hired by the Corps mishandled waste and even manipulated data to disguise radioactive material as less dangerous garbage. California regulators are investigating, too; they claim that more than 2,000 tons of Tonawanda debris was buried illegally at a San Joaquin Valley dump without a federal radioactive waste license. On Wednesday, a Senate committee will hold a hearing on the broader Corps decision to dispose of many of its Manhattan Project leftovers in such landfills." (Washington Post, April 10, 2000)
Note: the hearing on "Low activity radioactive waste" before the Senate Committee of Environment and Public Works had been scheduled for April 12, 2000, but was postponed.
"Some of those materials have made it to the White Mesa mill near Blanding where they are reprocessed for uranium left behind from the original processing." (Deseret News, April 25, 2000)

State complaints about the planned processing of uranium contaminated material from Tonawanda, NY, at the White Mesa uranium mill near Blanding are unfounded, a federal administrative judge ruled on February 9, 1999 (LBP-99-5).
Utah State officials objected to the shipments, noting IUC received $4,050,000 to handle a material that contained no more than $600,000 worth of uranium. Bill Sinclair called this "sham disposal" because uranium extraction was only a pretext to dispose of the waste in the mill's tailings pond.

Uranium Recovery Licensee Meeting with Deputy Executive Director for Regulatory Programs
"On May 12, 1998, the Deputy Executive Director for Regulatory Programs, the
Directors of the Office of Nuclear Material Safety and Safeguards and
Division of Waste Management, and staff from the Uranium Recovery Branch,
met with representatives of International Uranium (USA) Corporation (IUC).
The purpose of this Meeting was to discuss IUC's proposal to modify the
staff's "Final Position and Guidance on the Use of Uranium Mill Feed
Materials Other Than Natural Ores," which was published in the Federal
Register on September 22, 1995. IUC officially submitted the proposed
modifications to the Commission on May 6, 1998.
IUC's presentation focused on two aspects of the staff's "alternate feed"
guidance: (1) the prohibition of uranium mill licensees to receive and
process materials containing hazardous wastes regulated by the
Environmental Protection Agency (EPA); and (2) the need for mill licensees
to address financial considerations in support of any application to
receive and process alternate feed materials. When the staff raised
concerns about the potential for dual regulation with EPA at mill sites,
IUC stated its willingness to have issues related to hazardous materials
addressed at some later Time. If this component was removed from IUC's
proposal, the staff expressed some question about the need for the proposal
given that IUC has received license amendments in the past allowing it to
process alternate feed materials at the White Mesa uranium mill. The staff
also noted that, while it agreed with many of IUC's points concerning the
requirement to address financial considerations, a Presiding Officer's
decision on an earlier Hearing matter raised the need to consider an
economics test in the processing of alternate feed materials.
Also in attendance at this Meeting were representatives from the U.S. Army
Corps of Engineers (USACE), which manages the Formerly Utilized Sites
Remedial Action Program (FUSRAP ). Much of the material on FUSRAP sites can be considered as alternate feed materials, and the USACE sees recycling this material as a cost-effective way of cleaning up FUSRAP sites." (U.S. NRC Weekly Information Report for the Week Ending May 15, 1998)
