SEMI-ANNUAL RFI PROGRESS REPORT
1 September 2012 - 1 March 2013
ATK Launch Systems Promontory Facility
1. Description Of Work Completed
SWMU Assessment Report Schedule
As required by the Promontory Post-Closure Permit, ATK Launch Systems (ATK) provided
a schedule for submitting SWMU assessment reports or RFI work plans for the SWMUs
listed in Attachment 6 of the permit in to the Division in November 2007. After the Utah
Division of Solid and Hazardous Waste (UDSHW) has approved the schedule, ATK will
proceed with the assessment ofthe remaining SWMUs.
U.S. Air Force Installation Restoration Program (IRP) Report
The United States Air Force submitted an IRP report to the UDSHW in 1992 describing the
results of their investigation of the SWMUs at the old Air Force Plant 78 facility. ATK
purchased this facility in 1995. In a December 18, 2012 letter, the UDSHW recommended
additional characterization of three sites. ATK and the Air Force have an agreement to share
costs for additional environmental work at the facility and ATK needs to obtain concurrence
from the Air Force prior to proceeding. The time needed to resolve this matter is uncertain.
North Plant P Wells Investigation
As part of the corrective action for SWMUs at the North Plant, the UDSHW submitted a
letter on February 3, 2012 requesting that an additional well be installed in the same area as
wells P-2, P-6, and P-7. The intent of the new well, P-10, is to more accurately determine
flow direction in the uppermost perched aquifer. ATK submitted a well completion report to
the UDSHW in May 2012.
As discussed in the completion report, during the well development process, the water level
dropped to only 0.5 ft of water remaining in the well. Approximately five days later, the
water level had not changed. There was sufficient water to collect a grab sample on March
27, 2012 using a disposable bailer. Results of the sample are contained in the completion
report and included a 1,1- DCE concentration at 6.8 ppb and a TCE concentration at 9.5 ppp.
No perchlorate was detected.
As of February 2013, the water level continues to remain at approximately three inches. It is
believed that due to the tight formation, water does not recharge quickly or because it was
completed in a perched aquifer, the producing zone may be limited. Well P-10 indicates that
the perched zones have a limited northern extent. These are perched aquifers that appear to
be separate, isolated, and laterally discontinuous.
In a site visit on August 2, 2012 from Helge Gabert and Jeff Vandel, the decision was made
to wait until the spring of 2013 to see if water recharges back into Well P-10 and then collect
another sample. Based on that result, it will be determined if soil gas sampling will be
required at the site.
2. Summaries of All Findings
No corrective action work on SWMUs has been conducted during this reporting period.
3. Summaries of All Problems or Potential Problems Encountered During the Reporting
Period
There were no significant problems encountered during the reporting period.
4. Actions Taken to Rectify Problems
No problems were identified.
5. Projected Work for the Next Reporting Period
Monitoring the P wells and the Plant 3 Well 3A treatment system will be ongoing through the
next reporting period. ATK will pursue resolution of the Air Force cost sharing agreement
for additional characterization of the three IRP SWMUs on the Air Force Plant 78.
