ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 300

[FRL-6119-6]


National Oil and Hazardous Substances Contingency Plan; National 
Priorities List

AGENCY: Environmental Protection Agency.

ACTION: Notice of partial deletion of the Hanford 100-Area (USDOE) 
Superfund site from the National Priorities List.

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

SUMMARY: The United States Environmental Protection Agency (EPA) Region 
10 announces the deletion of portions of the Hanford 100-Area (USDOE) 
Superfund Site. The portions deleted are waste areas located in the 
100-IU-1 and 100-IU-3 Operable Units. The 100-IU-1 and IU-3 Operable 
Units are part of the Hanford 100 Area NPL Site located at the U.S. 
Department of Energy (DOE) Hanford Site, located in southeastern 
Washington State. The NPL constitutes Appendix B of 40 CFR part 300 
which is 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). This partial deletion pertains to all known 
waste areas located in the 100-IU-1 and 100-IU-3 Operable Units. EPA 
and the Washington State Department of Ecology have determined that no 
further cleanup under CERCLA is required and that the selected remedy 
has been protective of public health, welfare, and the environment.

EFFECTIVE DATE: July 8, 1998.

FOR FURTHER INFORMATION CONTACT: Dennis Faulk, Superfund Site Manager, 
USEPA, 712 Swift #5, Richland, Washington 99352; (509) 376-8631.

SUPPLEMENTARY INFORMATION: The partial deletion of the Hanford 100-Area 
(USDOE) NPL Site applies specifically to the 100-IU-1 and 100-IU-3 
Operable Unit waste areas located at the U.S. Department of Energy 
(DOE) Hanford Site, located in southeastern Washington State. The waste 
areas in the 100-IU-1 and 100-IU-3 Operable Units were cleaned up by 
the DOE between 1992 and 1994 using expedited response actions (ERA). 
At the Hanford Site, the term ERA is used to describe actions taken 
under CERCLA removal authority as described in 40 CFR 300.415. In 
February 1996, a no further action record of decision was signed 
documenting that previous ERA's had removed all contaminants from the 
waste areas in the 100-IU-1 and 100-IU-3 Operable Units to below 
cleanup levels for residential use established under the Washington 
State Model Toxics Control Act (MTCA). It should be noted, cleanup 
activities are continuing at other operable units of the Hanford 100 
Area NPL Site.
    This partial deletion 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)).
    A Notice of Intent to Delete for Partial Deletion was published on 
May 22, 1998 (63 FR 28317). The closing date for comments on the Notice 
of Intent to Delete was June 20, 1998. EPA received no comments.
    EPA identifies sites on the NPL that appear to present a 
significant risk to human health or the environment. As described in 
Sec. 300.425(e)(3) of the NCP, sites deleted from the NPL remain 
eligible for remedial actions in the unlikely event that conditions at 
the site warrant such action. Deletion of the waste areas from the NPL 
does not itself
