From the Leadville Herald Democrat:
Operable Unit 8 of the California Gulch Superfund Site has officially been deleted from the U.S. Environmental Protection Agency’s National Priorities List. The deletion will be recorded in the federal registry on Jan. 12, according to Commissioner Carl Schaefer. There are 12 total OUs in the Superfund site, with two others deleted: OU 2, which is Malta Gulch west of Leadville, and 10, which is Oregon Gulch south of Leadville. The next to be deleted after OU 8 will be OU 3, said Schaefer. In September, OU 9 should also be deleted. These deletions come with individualized institutional controls in place. These controls protect the remedies done on the mining waste that was left in place on these sites. California Gulch Superfund Site was added to the EPA priority list in 1982.
