National Oil and Hazardous Substances Pollution Contingency Plan; 
National Priorities List: Partial Deletion of the California Gulch 
Superfund Site

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule; notice of intent.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) Region 8 is issuing 
a Notice of Intent to Delete the Operable Unit 4, (OU4) Upper 
California Gulch; Operable Unit 5 (OU5), ASARCO Smelters/Slag/Mill 
Sites; and Operable Unit 7 (OU7), Apache Tailing Impoundment, of the 
California Gulch Superfund Site (Site), located in Lake County, 
Colorado, from the National Priorities List (NPL) and requests public 
comments on this proposed action. 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). 
The EPA and the State of Colorado, through the Colorado Department of 
Public Health and the Environment, have determined that all appropriate 
response actions at OU4, OU5 and OU7 under CERCLA, other than 
operation, maintenance, and five-year reviews, have been completed. 
However, this deletion does not preclude future actions under 
Superfund.

[[Page 47044]]

    This partial deletion pertains to all of OU4, OU5 and OU7. Operable 
Unit 2 (OU2), Malta Gulch Tailing Impoundments and Lower Malta Gulch 
Fluvial Tailing; Operable Unit 8 (OU8), Lower California Gulch; 
Operable Unit 9 (OU9), Residential Populated Areas; and Operable Unit 
10 (OU10), Oregon Gulch, were previously partially deleted from the 
NPL. Operable Unit 1 (OU1), the Yak Tunnel; Operable Unit 3 (OU3), 
D&RGW Slag Piles and Easement; Operable Unit 6 (OU6), Stray Horse 
Gulch; Operable Unit 11 (OU11), Arkansas River Floodplain; and Operable 
Unit 12 (OU12), Site-wide Surface and Groundwater Quality, are not 
being considered for deletion as part of this action and will remain on 
the NPL.

SUPPLEMENTARY INFORMATION: In the ``Rules and Regulations'' Section of 
today's Federal Register, we are publishing a direct final Notice of 
Partial Deletion for all of OU4, OU5 and OU7 of the California Gulch 
Superfund Site without prior Notice of Intent for Partial Deletion 
because EPA views this as a noncontroversial revision and anticipates 
no adverse comment. We have explained our reasons for this partial 
deletion in the preamble to the direct final Notice of Partial 
Deletion, and those reasons are incorporated herein. If we receive no 
adverse comment(s) on this partial deletion action, we will not take 
further action on this Notice of Intent for Partial Deletion. If we 
receive adverse comment(s), we will withdraw the direct final Notice of 
Partial Deletion and it will not take effect. We will, as appropriate, 
address all public comments in a subsequent final Notice of Partial 
Deletion based on this Notice of Intent for Partial Deletion. We will 
not institute a second comment period on this Notice of Intent for 
Partial Deletion. Any parties interested in commenting must do so at 
this time.
    For additional information, see the direct final Notice of Partial 
Deletion which is located in the Rules section of this Federal 
Register.
