RE: Closure of Solid Waste Managernent Units #642 and#655 atBuilding M-40
ATK Launch Systerns - Promontory Facility
uTD009081357
Dear Mr. Gooch:
The Division of Solid and Hazardous Waste has completed its review of the Phase I RFI R'eport for
SWMUs t*642 and#655. These two SWMUS were also inspected on November 6,2014. Both of these
SWMUs are located at Building M-40 which was used in the past for gnnding magnesium. It is
understood that ATK is planning to transfer the ownership of this building to its neighbor Autoliv.
SWMU #642isidentified as the former discharge area for wastewater from Building M-40. Wastewater
at the building was generated from the wash down of its interior to prevent the buildup of fine particles
of magnesium. Samples of the wash down water were collected while the building was active in1992.
ATK provided the analytical results for these samples after the site visit in November of 2014.
SWMU #655 is identified as the area on the east side of Building M-40 where a series of cyclones were
located. Fine particles of magnesium from the buildings ventilation system were captured in these
cyclones and collected. Magnesium fines that leaked from this system accumulated on the concrete pad
beneath the cyclones. This material was then swept onto the ground next to the pad.
In the Phase I RFI Report, ATKhas recommended that no further action be taken forboth SWMUs.
Based on our review of the Report, the analytical results for soil samples collected at the sites, the site
visit and the anallical results of the wastewater samples, the RFI Report for SWMUstt642 and #f655 is
hereby approved.

In conjunction with the approval of the RFI Report for these SWMUs, the Division has determined that
these SWMUs meet the requirements for no further action, as outlined in Section VI.F. of ATK's Post.
Closure Permit, since all Contaminants Of Potential Concern detected are either within background
concentrations, below EPA Regional Screening Levels (RSLs) orboth. Therefore, the Division concurs
with ATK's no further action recommendation. Closure of these SWMUs is also approved. In addition,
no land use reshictions apply to the SWMUs.
If you have any questions, please call JeffVandel at [phone].
