SUMMARY: The Environmental Protection Agency (EPA) Region 8 is issuing 
a Notice of Intent to Delete the Operable Unit 1 (OU1) Yak Tunnel/Water 
Treatment Plant; and Operable Unit 3 (OU3), Denver & Rio Grande Western 
Railroad Company (D&RGW) Slag Piles/Railroad Easement/Railroad Yard, 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 OU1 and OU3 under CERCLA, other than operation, 
maintenance, and five-year reviews, have been completed. However, this 
deletion does not preclude future actions under Superfund.

DATES: Comments must be received by March 10, 2016.

SFUND-1983-0002, by mail to Linda Kiefer, Remedial Project Manager,

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 OU1 and OU3 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.
    This partial deletion pertains to all of OU1 and OU3. Operable Unit 
2 (OU2), Malta Gulch Tailing Impoundments and Lower Malta Gulch Fluvial 
Tailing; Operable Unit 4 (OU4) Upper California Gulch; Operable Unit 5 
(OU5), ASARCO Smelters/Slag/Mill Sites; Operable Unit 7 (OU7), Apache 
Tailing Impoundment; Operable Unit 8 (OU8), Lower California Gulch; 
Operable Unit 9 (OU9), Residential Populated Areas; and Operable Unit

Mine Waste Pile; Operable Unit 11 (OU11), Arkansas River Floodplain; 
and Operable Unit 12 (OU12), Site-wide Surface and Groundwater Quality,
