National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List

The Environmental Protection Agency (EPA) Region 8 announces its deletion of Operable Unit 2 (OU2) of the California Gulch Superfund Site (Site) from the National Priorities List (NPL) and requests public comment on this action. The NPL constitutes appendix B of 40 CFR part 300, the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), which EPA promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended. This partial deletion of the California Gulch Site is in accordance with 40 CFR 300.425(e) and the Notice of Policy Change: Partial Deletion of Sites Listed on the National Priorities List, 60 FR 55466 (Nov. 1, 1995). This partial deletion pertains to the area addressed by OU 2, and includes the Malta Gulch Fluvial Tailing, Leadville Corporation Mill, Malta Gulch Tailing Impoundment, and the Malta Tailing Impoundment. EPA has issued a Record of Decision (ROD) for OU 2. EPA bases its partial deletion of this area on the determination by EPA and the State of Colorado, through the Colorado Department of Public Health and Environment (CDPHE), that all appropriate actions under CERCLA have been implemented at these sites. The California Gulch Site has been divided into 12 operable units. This partial deletion pertains only to OU 2 of the Site. Response activities will continue at the remaining OUs.
