ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 300

[EPA-HQ-SFUND-1999-0010; FRL-9999-76-Region 8]


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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: 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.

DATES: This action is effective September 20, 2019.

ADDRESSES: EPA has established a docket for this action under Docket 
Identification No. EPA-HQ-SFUND-1999-0010. All documents in the docket 
are listed on the http://www.regulations.gov website. Although listed 
in the index, some information is not publicly available, I.e.,

SUPPLEMENTARY INFORMATION: The portion of the site to be deleted from 
the NPL is: the residential portion of the site, identified as OU1, of 
the Vasquez Boulevard and I-70 Superfund Site, Denver CO. A Notice of 
Intent for Partial Deletion for this Site was published in the Federal 
Register (84 FR 2116) on February 6, 2019.
    The closing date for comments on the Notice of Intent for Partial 
Deletion originally was March 8, 2019; this date was extended to April 
8, 2019 on www.regulations.gov, by email to interested community 
members, at public meetings, and by publication of notices in local 
newspapers. Twenty-seven public comments were received and expressed 
concerns about non-Superfund projects in the area, the extent of the 
remedy, and the source of the contaminants. The non-Superfund projects 
in the area are overseen by other agencies. The properties that were 
remediated under the Superfund process do not have additional 
restrictions placed on them. EPA investigations identified possible 
sources of contamination and the residential properties that needed 
cleanup. The remedy implemented removed the contaminants associated 
with the site. Institutional controls are in place for those properties 
that did not provide access to sample or cleanup. A responsiveness 
summary was prepared and placed in both the docket, EPA-HQ-SFUND-1999-
0010, on 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.
