SEMI-ANNUAL RFI PROGRESS REPORT
1 March 2008 -1 September 2008
ATK Launch Systems Promontory Facility
1. Description Of Work Completed
SWMU Assessment Report Schedule
As required in the ATK Launch Systems INC. 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 ofthe permit. Upon Utah DSHW approval of
the schedule, ATK will proceed with the assessment ofthe remaining SWMUs.
Pilot test for Treatment of Perchlorate Contaminated Soils.
As described in the September 2005 RFI semiannual report, a perchlorate in soil treatment
pilot test was started. This soil was the result ofthe cleanup of perchlorate spills including
SWMU 677. The DSHW approved the test plan entitled Work Plan For a Corrective-
Measure Pilot Test to Evaluate Ex-Situ Remediation of Perchlorate-Contaminated Soil,
September 2005. The bio-piles showed slow degradation of perchlorate and a modified plan
was developed. ATK investigated the mixing of additional simple sugar electron donors and
M-705 perchlorate treatment bio- reactor effluent into the piles to enhance the biologic action
and drive the piles anaerobic. The findings showed that the use of only the bioreactor
effluent is sufficient to reduce the perchlorate. A modified test plan was approved by DSHW
in August 2007. Addition ofthe amendment took place in September 2007, with
encouraging results. Beginning in April 2008 sealed roll-off dumpsters were used to contain
the soil and bio-reactor effluent for the treatment process. Since that time approximately 300
yards of soil have been treated with treatment to below detection limits occurring in as little
as two weeks. At this time almost the entire amount of soil has been treated. A summary
table results is attached. A complete report will be forthcoming once all treatment is
completed.
Vegetable Oil Injection Pilot Testing
The DSHW has given approval for the pilot testing ofthe injection of vegetable oil at the
source areas ofthe M-136 bum grounds. This injection was completed in September 2007.
A summary of results ofthe testing is attached showing results from the injection well (Al)
and nearest down gradient well (T-2). These results indicate degradation ofthe perchlorate is
proceeding. The monitoring shows that the process will take additional time for the oil to
spread and for the microbial population to increase for degradation to occur. A report
detailing the results ofthis test will be forthcoming.
2. Summaries of all findings
Summary tables ofthe findings for the treatment perchlorate in soil of pilot test and the
vegetable oil injection pilot test are attached. Work on these projects is still ongoing and a
final or interim report detailing the results including raw data will be submitted in
forthcoming reports.
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
Thiokol 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. Pilot tests for perchlorate contaminated soil bio-remediation, vegetable
oil injection will be ongoing through the next reporting period.
