On March 30, 2018, U.S. Department of Energy Office of Legacy Management employee Mark Kautsky spoke briefly at a groundbreaking celebration for the Las Colonias Business Park in Grand Junction, Colorado. The business park repurposes a former uranium processing site, which was cleaned up as part of the Uranium Mill Tailings Radiation Control Act of 1978. Remediation of over 4,000 vicinity properties and the former processing site was completed in 1998. The scope of remediation involved transportation of 4.4 million tons of spent mill tailings to a licensed disposal facility southeast of Grand Junction.

The City of Grand Junction’s master plan for Las Colonias Park includes an amphitheater and other attractions.
