ATK Launch Systems, Report for December 2,2014 M81B Deluge Water Spill
The name, title, address and telephone number of the person reporting:
Jason Wells
Environmental Engineer

A description including the date, time, location and nature of the reported incident:
On December 2,2014, a 1 to 1.5 pound coin of propellant was being cut using a diamond-wire saw
in building M81B. As the cut was completed, the propellant ignited causing the automated deluge
system to activate. Deluge water flowed directly onto the sample at a rate of approximately 80
gallons/min for 10 min. The fire was quickly extinguished resulting in no damage to the structure
and minimal damage to the equipment. The deluge water exited the building at two points under
exterior walls. Most of the water exited under the south wall and infiltrated into a gravel roadway in
area directly adjacent to the building and up to 25 yards to the southwest. Water was also observed
exiting under the east wall of the building and across a concrete sidewalk before infiltrating into the
ground. The affected area was much smaller and was approximated at five feet by five feet. A
sample was taken of standing water inside the building and sent for perchlorate analysis.
Extent of injuries, if any:
There were no injuries associated with the spill and no immediate hazards to human health or
environment were present
The name and quantities of material(s) involved in the spill:
Approximately 800 gallons of water were released. The constituent of concern is ammonium
perchlorate (AP). The concentration of perchlorate detected in the water was 7 ppm.
An estimated quantity and disposition of the recovered material:
Approximately 800 gallons of water were released. Approximately 99% of the water flowed out of
the building at two exit points and soaked into the surrounding soil.
An assessment of actual or potential hazards to human health and the environment where applicable:
No immediate hazards to human health or environment were present.
Clean up status:
Soil in the affected area was sampled to determine perchlorate concentration. Two soil samples
were taken from the area to the southwest of the building that received the most water. One sample
was taken from the area to the east. The highest concentration of perchlorate detected in any of the
samples was 2.03 mg/kg. Using the EPA Region 9 May 2014, Regional Screening Level Industrial
Soil Table (THQ=0.1), the soils affected by the deluge water are lower than the published
ammonium perchlorate RSL of 82 mg/kg. No further action is planned at the site.
Steps taken to prevent recurrence:
An investigation of the incident is ongoing to determine root cause and corrective actions.
