Interim Measures Report ^^^^ ^^^^^^^^ ^^
SOLID & HAZARDOUS WASTE
INTRODUCTION
Water testing at ATK Launch Systems' Promontory Plant 3 facility indicated trichloroethylene
(TCE) and perchlorate present in groundwater extracted from Well 3A. TCE and perchlorate
concentrations were approximately 10 ppb and 60 ppb, respectively. Well 3A is the source water
for all Plant 3 operations. However, the water is not used for human consumption. In 2007, a
new pump-house was designed and constructed that used granular activated carbon (GAC) to
remove TCE from Well 3A water. The system was brought online at the beginning of 2008.
This report summarizes construction and startup activities and provides data indicating the
success ofthe treatment system thus far.
FACILITY CONSTRUCTION
Initial groundbreaking for the new pump-house began in August 2007 with building construction
beginning in late November 2007. The system was tumed on for the first time at the end of
December 2007. From January 2008 to April 2008, the system was operated under manual
control only. At the end of April 2008, instrument connections to the PLC and subsequently
PLC programming were completed. However, PLC data commimications to the central SCADA
unit has yet to be established. As-built drawings for the Well 3 A pump-house and GAC
treatment system can be found in Appendix A.
DATA COLLECTION
The first post-treatment sample was collected on January 8, 2008. However, due to manual
operation ofthe treatment system and the expectation that the automated system would be online
shortly, inaction ofthe sampling plan was postponed until the system was deemed fully
operational. Unexpected construction delays in January and early Febmary warranted a
modified monitoring program to ensure GAC treatment was effectively removing TCE. From
mid-Febmary to mid July, samples were taken weekly when possible. Post-GAC sample data is
reported in Appendix B.
Due to constmction delays and the postponement ofthe original sampling plan, a phone
conversafion was held between Jason Wells and Paul Hancock of ATK and Jeff Vandel of
DSHW on May 15, 2008. The call centered on the recent completion, as of late April 2008, of
the pump-house system to where it was now rurming automatically instead of manual control.
During the conversation it was agreed that constmction delays and partial completion ofthe
system had warranted modification to the sampling plan. The new plan agreed upon was to
continue weekly monitoring of perchlorate and TCE levels in post-GAC samples. When the
Page
existing GAC was exchanged for fresh material, the approved sampling campaign could be
implemented. It was agreed upon that the sampling campaign could be modified to exclude
collection of daily samples following initial startup. This was justified due to the large data set
already generated during the initial startup in January 2008 where no traces of TCE were
detected in a total of 20 samples. It was also agreed that the new sampling campaign would be
an initial sample taken after GAC exchange and then weekly samples taken for the first month of
operation. Continuous biweekly sampling has commenced as of September 5, 2008 per the
original sampling plan.
TREATMENT EFFECTIVENESS
As shown in Appendix B, the GAC treatment system has been very effective in removing TCE.
Initially, GAC appeared to remove some perchlorate. However, as expected, perchlorate
concentrations rebounded to historical levels as constituents with stronger affinity to the GAC
out-competed perchlorate for active sites. However, quarterly sample data from the M-201 and
M-205 septic tanks have generally shown no perchlorate residuals. One sample taken in October
2007 showed low levels of perchlorate in the M-201 septic tank effluent. The exact cause for the
detectable concentration is still unknown. However, it was hypothesized that it may have been
due to acute cleaning activities (i.e. hand washing, showering) from persormel that may have
been in contact with ammonium perchlorate. Also, the M-201 septic tank had noticeable solids
build up. This in combination with a temporarily increased flow may have led to less time for
complete biological reduction of perchlorate. To ensure appropriate residence time in cases of
increased flow, the M-201 septic tank was pumped and cleaned following the March 2008
sampling.
GAC EXCHANGE AND EMERGENCY OPERATION PROCEDURES
Each bed of GAC was expected to last approximately 3 months before TCE breakthrough was
observed. However, the original bed of GAC used in the system since startup showed no TCE
breakthrough after 6 months. Nevertheless, the GAC was exchanged on July 24, 2008 to ensure
unintermpted treatment of TCE. GAC was exchanged on-site without decoupling the carbon
vessel from the pump-house plimibing.
Originally, it was anticipated that the carbon vessel would be decoupled from the pump-house
plumbing and transported to the M-705 facility where GAC exchange commonly takes place.
However, a risk analysis revealed that this procedure posed threats to the water supply at Plant 3
if the carbon vessel should be seriously damaged during decoupling or transportation. This
consideration led to development of a new procedure that would allow the GAC to be exchanged
on-site whhout the need for decoupling or transportation. Furthermore, an emergency bypass
system is being considered as a final mechanism to supply water to Plant 3 to maintain volumes
required for fire suppression.

TREATMENT SUMMARY
To date the new Well 3 A pump-house has operated as expected with effective removal of TCE.
Perchlorate concentrations in septic tank effluent have been generally not detectable. Continued
attention will be focused on the ability ofthe septic tanks to treat acute perchlorate sources
originating in M-201 sanitary water.
