Addendum 2 to the Streamlined Approach for Environmental Restoration
Closure Report for Removal of the Use Restriction
This document constitutes an addendum to the Streamlined Approach for Environmental
Restoration Closure Report for Corrective Action Unit 454: Historical Underground
Storage Tank Release Sites, Nevada Test Site, Nevada, April 1998 as described in the
document Supplemental Investigation Report for FFACO Use Restrictions, Nevada Test
Site, Nevada (SIR) dated November 2008. The SIR document was approved by NDEP
on December 5, 2008. The approval of the SIR document constituted approval of each of
the recommended UR removals. In conformance with the SIR document, this addendum
consists of:
* This page that refers the reader to the SIR document for additional information
* The cover, title, and signature pages of the SIR document
* The NDEP approval letter
* The corresponding section of the SIR document
This addendum provides the documentation justifying the cancellation of the URs for
CASs:
* 12-25-08, Spill H950524F (from UST 12-B-1)
* 12-25-10, Spill H950919A (from UST 12-COMM-1)
These URs were established as part of Federal Facility Agreement and Consent Order
(FFACO) corrective actions and were based on the presence of contaminants at
concentrations greater than the action levels established at the time of the initial
investigation (FFACO, 1996).
Since these URs were established, practices and procedures relating to the
implementation of risk-based corrective actions (RBCA) have changed. Therefore, these
URs were re-evaluated against the current RBCA criteria as defined in the Industrial
Sites Project Establishment of Final Action Levels (NNSA/NSO, 2006). This
re-evaluation consisted of comparing the original data (used to define the need for the
URs) to risk-based final action levels (FALs) developed using the current Industrial Sites
RBCA process.
The re-evaluation resulted in a recommendation to remove these URs because
contamination is not present at these sites above the risk-based FALs. Requirements for
inspecting and maintaining these URs will be canceled, and the postings and signage at
each site will be removed. Fencing and posting may be present at these sites that are
unrelated to the FFACO URs such as for radiological control purposes as required by the
NV/YMP Radiological Control Manual (NNSA/NSO, 2004). This modification will not
affect or modify any non-FFACO requirements for fencing, posting, or monitoring at
these sites.
