Colorado Supreme Court overturns Summit County’s cyanide ban
Summit County, CO Colorado
SUMMIT COUNTY, Colorado “-The Colorado Supreme Court Monday essentially overturned Summit County, Colorados ban on cyanide heap-leach mining, ruling that the state has a “dominant interest” in ensuring orderly regulation of mining activities.
Joined by environmental groups, Summit County had argued that the practice of drizzling a diluted cyanide solution over low-grade piles of ore posed a serious threat to water quality.
Summit County adopted the regulations in 2004.
The Colorado Mining Association fought the ban through several court levels and won its first appeal in Summit County District Court. A subsequent Colorado Court of Appeals decision reinstated the local ban, leading to the Colorado Supreme Court.
