Sincerely Paul V. Hancock, Manager Environmental Remediation Enclosures: Notice published in newspapers listed above Fact Sheet for permit modification Monitoring Well Installation Plan FACT SHEET for the CLASS 2 POST-CLOSURE PERMTT MODIFICATION REOUEST by ATK THIOKOL PROPULSION ATK Thiokol Propulsion manufactures and tests rocket motors, propellants, flares and other similar materials at a facility located approximately thirty miles northwest of Brigham City, Utah in Box Elder County. Prior to 1988, waste treatment and disposal practices at the facility resulted in the release of a number of hazardous constituents to the water table aquifer. In September 1992, the Utah Solid and Hazardous Waste Control Board issued ATK Thiokol Propulsion a Post-Closure Permit for the hazardous waste treatment and disposal units that were operated at the facility. This permit outlined the conditions for closure of the units, and groundwater monitoring and corrective action requirements. ATK Thiokol Propulsion has requested to modify the Post-Closure Permit in accordance with Resource Conservation and Recovery Act (RCRA) regulations. The requested permit modification pertains to the expansion of the groundwater monitoring system. ATK Thiokol Propulsion would like to include within our groundwater monitoring system, those wells constructed since the permit was issued in September 1992, and also request authorization to construct six additional wells. These new wells will also be included as part of the groundwater monitoring system. Wells to be included within the system include: LF-1, LF-2, L- 3, and LF-4, completed in 1993; G-1, G-2, G-3, G-4, G-5, G-6, G-7, and G-8, constructed in 1996; and H-l, H-2, H-3, H-4, H-5, H-6, H-7, H-8, H-9, and H-10, completed in 2003. Wells to be completed and included in the monitoring system over the next twelve months are J-1, J-2, J- 3, J-4, J-5, and J-6. Locations and descriptions of these wells are available from both the Utah Division of Solid and Hazardous Waste, and ATK Thiokol Propulsion. None of these listed wells are compliance wells as defined in the Post-Closure Permit. The Division of Solid and Hazardous Waste (the Division) and ATK Thiokol Propulsion both believe that these wells should be included into the permitted groundwater monitoring system. Therefore, the Division is supportive of this requested modification. More detailed information on this Class 2 Modification may be obtained from Mr. Jeff Vandel at the Utah Department of Environmental Quality, Division of Solid and Hazardous Waste, 288 North 1460 West, Salt Lake City, Utah 84114. Mr. Vandel can also be reached at (801)538- 9413. NOTICE On September 1,1992 the Utah Solid and Hazardous Waste Control Board issued a Post- Closure Permit to ATK Thiokol Propulsion for post closure care and corrective action of the M-136 Liquid Thermal Treatment Area and Solid Waste Management Units at their facility located in Box Elder County, Utah. ATK Thiokol Propulsion has submitted a request to modify this permit to include additional groundwater monitoring wells into the monitoring system. A 60 day public comment period will commence on November 13, 2003, and end on January 12, 2004, at 5:00 p.m. MST. A public information meeting will be held on December 11, 2003 at 2:00 pm in the auditorium at the Brigham City Library located at 26 East Forest St. Brigham City, Utah. Information conceming this request can be obtained from ATK Thiokol Propulsion through John Holladay at (435) 863-6895.
