This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status.

The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.
Environmental Protection Agency.
The Environmental Protection Agency (EPA) Region 8 announces the deletion of the remaining portions of Operable Unit 9 (OU9), the Residential Populated Areas, of the California Gulch Superfund Site (Site), located in Lake County, Colorado, 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 to the remaining portions of OU9. Operable units 1, 3, 4, 5, 6, 7, 11 and 12 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, 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.
Effective Date: This action is effective September 21, 2011.
Information Repositories: EPA has established a docket for this action under Docket Identification No. EPA-HQ-SFUND-1983-0002.

The portion of the site to be deleted from the NPL is: the remaining portions of OU9 of the California Gulch Superfund Site, located in Leadville, Lake County, Colorado. A Notice of Intent for Partial Deletion for this Site was published in the Federal Register on May 24, 2011 FR Doc No: 2011-12766.
The closing date for comments on the Notice of Intent for Partial Deletion was June 23, 2011. Three public comments were received: two requesting continuation of the voluntary investigation/remediation program and one recommending that, because OU12, Site-wide Water Quality, is not ready for deletion, OU9 should not be deleted. The deletion is still appropriate, because all appropriate response actions have been completed, and the operable unit is in operations and maintenance. The current operations and maintenance program, the Lake County Community Health Program Phase 2, provides opportunities for investigation and soil remediation, if the Program's Work Group determines that lead in residential soil is contributing to an elevated blood lead in a child or pregnant/nursing woman. Under current EPA policy for partial deletion, one operable unit or environmental medium can be deleted irrespective of the readiness for deletion of other operable units or the site as a whole. A responsiveness summary was prepared and placed in both the docket, EPA-HQ-SFUND-1983-002, on http://www.regulations.gov, and in the local repositories listed above.
EPA maintains the NPL as the list of sites that appear to present a significant risk to public health, welfare, or the environment. Deletion of a site from the NPL does not preclude further remedial action. Whenever there is a significant release from a site deleted from the NPL, the deleted site may be restored to the NPL without application of the hazard ranking system. Deletion of portions of a site from the NPL does not affect responsible party liability, in the unlikely event that future conditions warrant further actions.Start List of Subjects
