SEMI-ANNUAL RFI PROGRESS REPORT
1 March 2010 -1 September 2010
ATK Launch Systems Promontory Facility
1. Description Of Work Completed
SWMU Assessment Report Schedule
As required in the ATK Launch Systems, September 20, 2007 Promontory Post-Closure
Permit, ATK submitted a schedule for submitting SWMU Assessment Reports or RFI work
plans for the SWMUs listed in Attachment 6 of the permit. Upon Utah DSHW approval of
the schedule, ATK will proceed with the assessment of the remaining SWMUs.
Vegetable Oil Injection Pilot Testing
The DSHW gave approval for a pilot test of vegetable oil injection at the source areas in the
M-136 bum grounds. This injection was completed in September 2007. Summaries of the
interim testing results have been provided in previous progress reports. A final report was
submitted to the Division on June 7, 2010. The conclusion of the report was that using
vegetable oil as a substrate to stimulate biological degradation is a viable way to treat volatile
organic compounds and perchlorate at M-136 and that a broader application would be
successful. Samples will continue to be collected to assess the long term effects of the
treatment.
Plant 3 Well 3A Treatment Summary Reports
The treatment system at the Promontory Plant 3 well 3A has been monitored quarterly
according to the Division approved plan. The plan includes a request for a summary of the
previous year to date monitoring data be included in the Semi-Annual report. This summary
is included as an attachment to this report The treatment system continues to remove TCE
to below detection limits with a carbon replacement interval of every 6 months. In addition,
perchlorate removal in the two septic tanks, M-201 and M-205, continues to be effective.
2. Summaries of all findings
Summary tables of the Plant 3 well treatment are attached.
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
ATK continues to review all available information and pursue all avenues
to resolve any uncertainty associated with the solid waste management units.
5. Projected work for the next reporting period
Efforts for the next reporting period will focus on receiving approval for voluntary corrective
measures, investigating additional solid waste management units, and SWMU Assessment
report preparation. Monitoring at the vegetable oil injection wells, and the Plant 3 treatment
system monitoring will be ongoing through the next reporting period.
