They rolled out legislation, immediately opposed by industry, that would require mining companies to make reclamation plans that include an end date for water treatment to remove pollution.
Proponents say this would force a responsible assessment, before mining begins, of how best to minimize harm. The bill also would force companies to post better financial assurance to cover costs of cleanup. For companies to operate in the Cowboy State, whether pumping uranium or digging coal, they have to set aside money for the environmental cleanup of the site. Firms can do that in a number of ways, from traditional insurance to posting collateral to applying for self-bonds. However, the practice of self-bonding, which critics say is simply an IOU to the state, would be greatly restricted under the proposed rules, a win for environmental groups that fought the practice during the coal bankruptcy period and a headache for firms that want self-bonding to remain an option in Wyoming.
Companies would only be able to apply for self-bonding for mines with more than 10 years of operations left. The amount a company is allowed to self-bond is tied to credit ratings from reputable firms like Moody’s Investment Service, Standard and Poor’s Corporation or Fitch Ratings. No company can self-bond more than 75 percent of its reclamation obligations. Submit comments by March 19, 2018.
Global competition in a glutted uranium market has pressured some companies to cut staff, defer expansion and produce only enough uranium to meet long- term contracts. A sliding scale on taxes, with lower prices meaning little to no payments to the state, could alleviate strain on industry, companies argued before the Joint Minerals Committee in Casper. The industry could strengthen despite the downturn, representatives argued, and offer more to the state in the long run. Lawmakers were not convinced a tax cut would benefit the state, however, given the choked revenue streams from Wyoming’s oil, gas and coal industries in recent years, all of which have higher tax burdens than uranium. Texas to amend in situ leach rules at request of uranium industry On Dec. For Classes of Facilities in the Hardrock Mining Industry, on December 1, 2016.
By requiring owners and operators of hardrock mining facilities to demonstrate financial responsibility, this proposed rule would increase the likelihood that those owners and operators will have funds necessary to address the CERCLA liabilities at their facilities, thus preventing the burden of cleanup from falling to other parties, including the American taxpayer.

The petition focuses on so-called “zombie mines” that have been reopened after long periods of inactivity.
It asks for limits on how long a mine can remain on standby, as well as new environmental reviews when an old mine reopens. It also proposes regular inspections of inactive mines, long-term water monitoring and firm deadlines for reclamation. The Grand Canyon Trust prepared the petition with the support of environmental groups, native nations and local governments, including the Havasupai Tribal Council and Coconino County. Energy Fuels Resources, a Colorado-based company, has reopened two uranium mines in the Grand Canyon area in recent years , and plans to open another this fall. View Grand Canyon Trust release Aug.

But the standards need to be clarified in order to ensure that the quality of the underground water is documented before mining — and they need to be strengthened to ensure protection of groundwater quality in surrounding aquifers.
