Organizations from Colorado, Nebraska, and South Dakota that are working against proposed uranium mines held a press conference on Saturday, June 21, 2008. Representatives from North Dakota and Wyoming joined in the press statement, which was issued from Mustang Hollow Ranch in rural Nunn in Weld County, CO. Mustang Hollow Ranch is a small business located immediately adjacent to an area where uranium exploration drilling is occurring as part of a proposed in situ leach uranium mine.

On May 20, 2008 Governor Bill Ritter signed House Bill 08-1161 (), the Land and Water Stewardship Act of 2008, into Colorado law. On June 2nd, Senate Bill 08-228 () was enacted which would increase public disclosure of a notice, by a mining company, of intent to conduct mining operations. While passing this legislation helped tighten uranium mining laws in the state, the struggle to protect Colorado from the possible hazards of uranium mining is far from over.

Denver. May 20, 2008. Gov. Bill Ritter today signed into law a measure that will strengthen water-protection, reclamation and other requirements as the state experiences a resurgence of uranium mining.

House Bill 1161, called the "Land and Water Stewardship Act of 2008" by supporters, was sponsored by Reps. John Kefalas and Randy Fischer and Sens. Steve Johnson and Bob Bacon. It stems from a proposal by a Canadian-based company to begin in situ leach mining in Weld County. The process uses high-pressure water injection to extract uranium from the earth.
