National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List: Partial Deletion of the Vasquez Boulevard and I-70 Superfund Site

The Environmental Protection Agency (EPA) Region 8 announces the deletion of the operable unit 1 (OU1) of the Vasquez Boulevard and I-70 Superfund Site (Site) located in the City and County of Denver, CO, from the National Priorities List (NPL). The NPL, promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). This partial deletion pertains only to OU1, the residential portion of the Site. The operable unit 2 (OU2) and operable unit 3 (OU3) will remain on the NPL and 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 Environment (CDPHE), have determined that all appropriate response actions under CERCLA, other than operation and maintenance, monitoring and five-year reviews, have been completed. However, the deletion of these parcels does not preclude future actions under Superfund.
