Box 144880 Salt Lake City, Utah 84114-4880 Re: Financial Assurance Revision OCT 2 5 2010 UTAH DIVISIUIM u^ SOLID & HAZAROOUS WASTE. c/tOlOiOiL^O^ ATK Launch Systems -Promontory FacilityUTD009081357 ^ ATK Launch Systems - Bacchus Facility UTDOO 1705029 Dear Mr. Anderson: ATK Launch Systems proposes to adjust financial assurance coverage in the amounts shown below. The September 30, 2010 Promontory permit modification increased closure costs to a total of $629,659. We have also re-calculated the Promontory post- closure cost estimate following the requirements in the Post- Closure Permit Module III.D. The post-closure cost estimate was provided by a third party, and is based on hiring a third party to conduct post-closure care activities. A copy of the estimate is attached. The net present value for post-closure care is based on the annual cost of $54,144 for years 18 through 30 of the post-closure care period which started on September 21, 1992. There are no changes in costs for the Bacchus facility. The total cost for both facilities is $1,610,894. EPA ID Number Facility Name and Address Closure Cost Post-Closure Cost UTD009081357 ATK Launch Systems- Promontory P.O.

Box 98 Magna, UT 84044-0098 $396,100 $0 ATK is submitting this request following the requirements in Module II.G.2 for submitting a revised post-closure cost estimate. Since the Post-Closure Permit does not contain a cost estimate, we believe the cost estimate can be revised without modifying the exisfing permit.
