Box 144880 Salt Lake City, Utah 84114-4880 Subject: ATK Launch Systems Promontory Facility, Semi-Annual RFI Progress Report for March 2007 - September 2007, Promontory EPA ID #UTD009081357 Dear Mr. Downs Attached, please find the ATK Launch Systems Promontory Facility Semi-Annual Progress Report for March 2007 - September 2007. If you have questions regarding this report, please contact Paul Hancock at (435) 863-3344. Sincerely, David P. Gosen, P.D:, Director Environmental Services c: Walter L. Baker, Direcior, Division of Water Quality SEMI-ANNUAL RFI PROGRESS REPORT 1 March 2007 -1 September 2007 - ATK Launch Systems Promontory Facility 1. Description and estimation of the percentage of the RCRA Facilities Investigation completed New SWMU # 680 An additional new SWMU # 680 was described in a letter sent lo the Division of Solid and Hazardous Waste on August 28, 2007. A release was discovered in the piping in M-115 propellant washout facility. The release likely occurred under the concrete floor and footing ofthe building and is not practical or safe to fiarther investigate al this time. When the leak was discovered the pipe was disconnected and new above ground piping installed. It is unknown what amount was released but il appears lo be minimal as the close loop process did not note a water loss. The constituents in the water are ammonium perchlorate ranging from 3% lo 11 %, wilh two corrosion inhibitors, sodium nitrite al 0.08 %, and ammonium penlaborate al 0.05%. The release area is essentially capped by the building and the thick concrete flooring preventing additional water intmsion. Additionally, concrete covers a large area oulside ofthe building which drains precipitation into a sump system. Therefore, there is little polentiai for waler to drive the contamination deeper. However, we will continue lo monitor wells in the area for any increases in perchlorate. Investigation of potential J-4 TCE Up Gradient Source Area. Recently completed well J-4 has seen significantly increasing levels of TCE with no clear indication ofa source. The canyon directly east of J-4 has several small test facilities and also an area of constmcfion debris. To determine if these areas are potenfial source areas a series of passive soil gas modules were placed in two cross sections within the canyon. The modules were installed the end of August and will be retrieved in September. A report on the results ofthis investigation will be provided in a future progress report. Pilot test for Treatment of Perchlorate Contaminated Soils. As described in the September 2005 RFI semiannual report, a perchlorate in soil treatment pilot test was started. This soil was the result ofthe cleanup of perchlorate spills including SWMU 677. The DSHW approved the test plan entitled Work Plan For a Corrective-Measure Pilot Test lo Evaluate Ex-Silu Remediation of Perchlorate-Contaminated Soil, September 2005. The bio-piles have not appeared to have gone totally anaerobic at this point as perchlorate degradation has been minimal and the use of animal manures has added additional nitrate. ATK has been investigating the mixing of additional simple sugar electron donors and M-705 perchlorate Ireatmenl bio- reactor effluent into the piles lo enhance the biologic acfion and drive the piles anaerobic. It appears that the use of only the bioreaclor effluent is sufficient lo reduce the perchlorate. A modified test plan was approved by DSHW in August 2007. Addition ofthe amendment is now proceeding. Additional Perchlorate Treatment Pilot Testing The DSHW has given approval for the pilot testing to of two groundwater treatment technologies. One is the injecfion of vegetable oil al the source areas of the M-136 bum grounds. This injection is scheduled for implementafion in September. The olher pilot test is the continuation ofthe sparging of electron donor up-gradient of well B-6. In this instance a different donor ethanol, was sparged into the subsurface ground water for the period of June 22 through July 23. A report detailing the results ofthis test will be forthcoming. 2. Summaries of all findings No findings to report at this fime. Work on these projects will begin in the next reporting period. 3. Summaries of all changes made in the RCRA Facility Investigation during the reporting period The ongoing implementation ofthe perchlorate contaminated soil treatment pilot test as a means of treating perchlorate releases to the soil. Additional pilot tests for treatment of contaminated water as specified above. 4. Summaries of all contact with representatives of the local community, public interest groups or State Government during the reporting period Correspondence regarding RFI activities has been limited to the Division of Solid and Hazardous Waste and the Division of Water quality. 5. Summaries of all problems or potential problems encountered during the reporting period There were no significant problems encountered during the reporting period. 6. Actions taken to rectify problems Thiokol continues to review all available information and pursue all avenues to resolve any uncertainty associated with the solid waste management units. 7. Changes in personnel during the reporting period There are no changes in personnel. The existing environmental staff will confinue to conduct the sampling when possible. Contractors will be used when specialized equipment is required. 8. Projected work for the next reporting period Efforts for the next reporting period will focus on receiving approval for voluntary correcfive measures, investigating additional solid waste management units, and report preparation. Pilot tests for perchlorate contaminated soil bio- remediation, vegetable oil injecfion will be ongoing through the next reporting period. 9. Copies of daily reports, inspection reports, laboratory and monitoring data Copies ofthe test data for these pilot tests will be provided to the DSHW as they become available through the next reporting period.
