Abandoned uranium mines in Utah

Abandoned uranium mines near Maverick Point in Manti-La Sal National Forest, San Juan County, Utah

Forest Service invites comment on scope of EIS for reclamation of abandoned uranium mines in Manti-La Sal National Forest: The Forest Service will prepare an Environmental Impact Statement (EIS) to document the analysis and disclose the environmental impacts of the Maverick Point Forest Health Project. This project is designed to achieve goals of increasing aspen and ponderosa pine forest stand resilience and resistance to insects, disease, drought, and wildfire by altering stand density, species composition, and age class structure via use of timber harvesting and prescribed fire.
Project activities also seek to maintain or improve the productivity and diversity of wildlife habitat and improve watershed health through restoring or protecting selected springs or active head cuts, closing unauthorized roads, and reclaiming abandoned uranium mine adits and waste rock. [...]
Comments concerning the scope of the analysis described in this notice must be received by February 14, 2013.

A 71-year-old Navajo woman is partly to thank for the cleanup of an abandoned uranium mine that lies west of Utah's Monument Valley. Elsie Mae Begay has spent more than 30 years living among the remnants of the Skyline Mine, which she says have sickened and killed her family members. She took her story of the dangers of uranium across her reservation, to college campuses and Congress, along with a documentary outlining her family's plight. The federal government now is wrapping up a $7.5 million project that uses a cable system to take the contaminated waste up a mesa [Oljato Mesa] where it came from. The cleanup marks the first significant remediation of a mine site on the country's largest American Indian reservation where abandoned uranium mines number in the hundreds. (AP Sep. 5, 2011)

EPA wraps up cleanup of abandoned Skyline uranium mine: The U.S. Environmental Protection Agency has wrapped up a $7.5 million project that used a cable system to transport uranium waste back up a mesa where it came from. The cleanup of the Skyline Mine near the Arizona-Utah border means residents living below Oljato Mesa no longer have to worry about continued exposure to radiation. It also marks the first significant remediation of a mine on the Navajo Nation, where such sites number in the hundreds.
A lined repository atop the mesa now holds 25,000 cubic yards of uranium waste that was piled up on the valley floor and gathered from around an arroyo. The EPA's Jason Musante says the agency is working with tribal officials on a monitoring plan to make sure the liner holds up as expected. (AP Oct. 19, 2011)

Utah State divisions agree on handling bats in abandoned uranium mines

The state Division of Wildlife Resources, which is charged with managing bats in Utah, and the Division of Oil, Gas and Mining (DOGM), which is responsible for reclaiming abandoned mines, have signed an agreement that lays out ways in which DOGM can seal old mines dangerous to people without hurting any bat populations found inside. In cases where surveys find bats living in an abandoned uranium mine, the agreement specifies that the divisions will confer on an acceptable approach, with Wildlife Resources' officials having the final say. In many cases, the agreement will allow Oil, Gas and Mining officials to use grates to keep people out but let bats enter and exit. (The Salt Lake Tribune Apr. 23, 2010)

USGS report investigates contaminant dispersion from abandoned Fry Canyon uranium/copper project site to surface and ground water

"The Fry Canyon uranium/copper project site in San Juan County, southeastern Utah, was affected by the historical (1957–68) processing of uranium and copper-uranium ores. Relict uranium tailings and related ponds, and a large copper heap-leach pile at the site represent point sources of uranium and copper to local soils, surface water, and groundwater. This study was designed to establish the nature, extent, and pathways of contaminant dispersion."

USGS study finds elevated trace element concentrations in leachate from abandoned uranium waste dumps in the San Rafael Swell, Utah

"During July and August of 2006, 117 solid-phase samples were collected from abandoned uranium waste dumps, geologic background sites, and adjacent streambeds in the San Rafael Swell, in southeastern Utah. The objective of this sampling program was to assess the nonpoint source chemical loading potential to ephemeral and perennial watersheds from uranium waste dumps on Bureau of Land Management property. [...]
Approximately 56 percent (48/85) of the leachate samples extracted from uranium waste dumps had one or more chemical constituents that exceeded aquatic life and drinking-water-quality standards. Most of the uranium waste dump sites with elevated trace-element concentrations in leachates were along Reds Canyon Road between Tomsich Butte and Family Butte. Twelve of the uranium waste dump sites with elevated trace-element concentrations in leachates contained three or more constituents that exceeded drinking-water-quality standards. Eighteen of the uranium waste dump sites had three or more constituents that exceeded trace-element concentrations for aquatic life water-quality standards. The proximity of the uranium waste dumps in the Tomsich Butte area near Muddy Creek, coupled with the elevated concentration of trace elements, increases the offsite impact potential to water resources.

White Canyon uranium mill (also known as Hite, Utah, uranium mill), San Juan County

The small mill, essentially a pilot-scale operation, began operating in mid 1949. The mill was shut down at the end of 1953. Over its operating life, the mill treated 26,358 (short) tons of ore averaging 0.43 percent U3O8. On average, 43 percent of the ore's uranium was not recovered, but remained in the mill tailings impounded at the mill site.
The mill was dismantled by Vanadium Corporation of America (VCA) in about 1954. Based on the quantity of ore treated at the mill, the Atomic Energy Commission (AEC) estimated that some 26,000 tons of tailings were originally impounded at the mill site.
In November 1963, when the future Lake Powell was scheduled to begin forming behind the Glen Canyon Dam, the AEC requested the Department of Health, Education, and Welfare to determine what would be the future radiation effect of the White Canyon mill tailings, which contained an estimated 13 grams of radium-226, when flooded by the lake. The study concluded that, given the isolated location of the site and the dilution factor represented by the large volume of water in the lake, the mill tailings could remain at the former mill site and be inundated by the lake waters. It was postulated that, after a period of years, the natural action of sedimentation in the lake would cover the tailings under several feet of silt. After the study, VCA in the mid 1960s removed some "high grade" tailings material from the former mill site and presumably reprocessed those tailings at its Shiprock, New Mexico, mill.
The former mill site and the old tailings pile were covered by rising waters of Lake Powell in 1965.
Two independent studies of large mouth bass (Micropterus salmoides) from Lake Powell report that selenium concentrations in the fish greatly exceed national averages. This abnormally high selenium concentration in fish reflects the high concentration in the reservoir. Selenium transported from the submerged tailings piles is a likely contributor to the high concentration.

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."
