Final Second Five-Year Review Report Fort Ord Superfund Site ...

10.0 INTERIM ACTION SITES ROD
This section presents background information on the IA Sites ROD; a summary of remedial actions and a
technical assessment of the actions taken at these sites; identifies any issues related to the protectiveness
of the remedies based on the review; presents recommendations and follow-up actions, if needed, to
address issues identified during the review; and provides a statement regarding the protectiveness of the
site remedies.
10.1 Background
An IA ROD (IAROD) was signed in March 1994 (Army, 1994a). The IAROD was based on the IA FS
and proposed plan (HLA, 1993a; HLA, 1993b). The IAROD defined criteria that a site must meet to
qualify as an IA site, and described the approval process for implementing IAs. The primary criteria
include: (1) the maximum depth of affected soil that could be addressed as an IA was 25 feet bgs, and
(2) the volume of affected soil that could be addressed as an IA was limited typically to between 500 and
5,500 cy. The cleanup goals and approach for these sites were consistent with those presented for the
OUs and RI sites at Fort Ord.
For each proposed IA (IA) site, the process began with a site characterization investigation and report.
The regulatory agencies reviewed the report and approved it after their comments were addressed. If the
site met the criteria, an IA approval memorandum was submitted for regulatory agency approval. The
public was notified that an approval memorandum was submitted, and if the approval memorandum was
approved, public notice of the proposed action was provided two weeks before work began. The IA was
then implemented and a Confirmation Report was prepared. If the report was approved, the site was
included in the IAROD process. If the confirmation report was not approved, it was resubmitted after
additional action was taken to address agency concerns. If it was determined that the contamination was
too extensive to be remediated under the IAROD, then the site was transferred to the RI sites category.
An RI/FS report would then be prepared for the site and it would be included in the Basewide RI Sites
ROD.
