The Uranium Resources Stewardship Act introduced by U.S. Reps. Martin Heinrich and Ben Ray Luján would shift the regulation of uranium mining from the 1872 Mining Law to the Mineral Leasing Act and require royalty payments to federal and state governments similar to those paid by the coal, oil and gas industries.

Last year, Udall introduced SB 796, which would have studied “whether uranium should fall under the Mineral Leasing Act system and be subject to a federal royalty that is shared with the state.” But Senate Majority Leader Harry Reid, D-Nev., has consistently blocked any significant reform of the 1872 Mining Law, which was passed by the Grant administration to encourage settlement of the West by miners in the late 19th century.

“It’s time to seriously consider whether uranium should still be classified as a ‘locatable mineral’ governed by the hard-rock mining laws,” Udall told the Colorado Independent last year. Critics of the U.S. uranium mining industry say it is dominated by foreign companies taking advantage of a lack of royalties on federal lands, and that too often toxic waste has been left for American taxpayers to clean up.

Udall is a proponent of reviving the U.S. nuclear power industry to combat climate change by reducing the amount of fossil fuels being consumed to produce electricity. But members of the Colorado conservation community say the state has for too long been on the hook for the “dirty front end” of the uranium mining industry.

“Taxpayers have been fleeced out of millions of dollars in royalties from uranium companies mining on public lands,” Earthworks Policy Director Lauren Pagel said in a release. “The Uranium Resources Stewardship Act charges a moderate 12.5-percent royalty on uranium, which will allow the industry to contribute to cleaning up old uranium mine sites that continue to pollute water and harm nearby communities.”

Uranium prices have dropped in recent weeks due to the ongoing nuclear crisis in Japan, but they’re still up dramatically over the last decade, and Udall says the United States must continue to pursue new nuclear power facilities. He’s introduced a bill this session that would facilitate the construction of smaller, “modular” nuclear reactors.

Unlike oil and gas extraction, pulling hard-rock minerals like uranium, gold and copper out of the ground is a royalty-free proposition in the United States, despite the often enormous costs of cleaning up public lands after the fact.

The Environmental Protection Agency in a filing on Monday noted that hard-rock mining has impacted 40 percent of all western watersheds and that nationwide 28 percent of the toxic pollution generated in the United States comes from the mining industry –- the most of any sector. The EPA also concluded mining represents a major taxpayer burden because of cleanup costs.

The EPA filing was presented during a hearing Tuesday of the U.S. Senate Energy and Natural Resources Committee chaired by Colorado Sen. Mark Udall. Former Colorado Sen. Ken Salazar, now Secretary of the Interior, testified the Obama administration wants to see the 1872 Mining Law reformed in the current Congress.

Mining reform legislation has been introduced in both the House and the Senate, and both versions would set up some sort of royalty structure for hard-rock mining on federal lands. The 137-year-old system of filing for relatively inexpensive and easy-to-acquire “patents” would be scrapped, and a fund would be set up to pay for massive cleanup efforts that for decades have been passed off to taxpayers when mining companies go bankrupt. [...]

Salazar likely will get a fight from Sen. Majority Leader Harry Reid, D-Nevada, who in the past has blocked reform measures because of gold mining interests in his home state.
