Re: Satellite Accumulation Area Guidance, Bacchus Facility EPA ID #UTD001705029
Dear Mr. Hansen:
This letter is in response to the Division’s request that the Bacchus facility modify the way that
we manage our Slum Sheds or Satellite Accumulation Areas (SAA’s) outside of buildings where
energetic waste is manufactured and handled at the Bacchus facility. NGSC concurs that these
sheds should be managed as Central Accumulation Areas (CAA’s). Our internal Hazardous
Operation Procedures (HOPS) require us to remove any energetic waste placed in a slum shed
within 3 days, so a change to weekly inspection of the slum sheds completed as required by the
CAA rules. Additionally, appropriate modifications to our quick reference guide will be made to
reflect the change from SAA to CAA.
If you have questions or comments, please contact me at 801-251-2166 or Robert Weston at 801-
251-2303.
Sincerely,
Kris H Blauer
