This final rule is effective on Oct. 24…
This partial deletion pertains to the Operable Unit 4, Upper California Gulch (media of concern–waste rock and fluvial tailing piles); Operable Unit 5, ASARCO Smelters/Slag/Mill Sites (media of concern–slag and soil); and Operable Unit 7, Apache Tailing Impoundment (media of concern–tailing and soil), of the California Gulch Superfund Site (Site). Operable Unit 2, Malta Gulch; Operable Unit 8, Lower California Gulch; Operable Unit 9, Residential Populated Areas; and Operable Unit 10, Oregon Gulch were partially deleted by previous rules. Operable Unit 1, the Yak Tunnel/Water Treatment Plant; Operable Unit 3, the Denver & Rio Grande Western Railroad Company Slag Piles/Railroad Easement/Railroad Yard; Operable Unit 6, Starr Ditch/Penrose Dump/Stray Horse Gulch/Evans Gulch; Operable Unit 11, the Arkansas River Floodplain; and Operable Unit 12 (OU12), Site-wide Water Quality will remain on the NPL and is/are not being considered for deletion as part of this action. The EPA and the State of Colorado, through the Colorado Department of Public Health and the Environment, have determined that all appropriate response actions under CERCLA, other than operation, maintenance, and five-year reviews, have been completed. However, the deletion of these parcels does not preclude future actions under Superfund.”
