From the Denver Business Journal (Kathy Proctor):
The new rules require uranium companies planning an “in-situ leach” operation — a process that injects chemicals to leach the uranium from the ground without resorting to strip mining — to protect groundwater. Powertech proposed using such an in-situ mining technique on its Centennial project in Weld County, believed to hold 12.8 million pounds of uranium.
The new rules also requires applicants for in-situ uranium mining to get information on groundwater quality prior to prospecting for uranium. In an Aug. 6 filing to the reclamation board, Powertech said requiring pre-prospecting groundwater studies “economically and technically impracticable at best — impossible at worst” because the prospecting has to happen in order to study the groundwater. “This results in an obvious Catch 22 which would be fatal to any serious potential in-situ recovery project,” said the filing by Powertech President Richard Clement and attorney John Fognani with Denver’s Fognani & Faught PLLC…
Environmental groups involved in the rulemaking said they, too, approved of the board’s decision. “The state mining board took decisive action to protect our water and land from uranium pollution,” said Matt Garrington, program advocate of Environment Colorado, in a statement. “Today is a triumph for our land and water.”
