Baker, Division Director, Utah Division of Water Quality Orbital ATK, Inc. • P.O. Box 707, Brigham City, UT 84302 • 435-863-3511 SEMI-ANNUAL RFI PROGRESS REPORT March 1, 2017 - September 1, 2017 ATK Launch Systems Promontory Facility 1. Description Of Work Completed SWMU Investigations and Closures this Reporting Period In a March 10, 2017 letter the UDWMRC closed with no further action 15 SWMUs. These SWMUs are associated with water discharge sites and old mining prospects. Jeff Vandel with the UDWMRC has reviewed the RFI reports and inspected each of these sites. These inspections were conducted in July of 2016. Photographs, descriptions and other historical information were provided in reports from ATK to the UDWMRC. The letter also had additional questions on 9 other SWMUs that had been investigated. ATK submitted more information and responses to these questions in a May 1st 2017 letter. This additional information supports a no further action disposition for these SWMUs. SWMU 208 The area called M-136 at the ATK facility was historically used to dispose of waste materials and is currently permitted to treat reactive wastes. One of the locations at M-136 was a shallow depression called a pit that was used to dispose of waste oils. This pit was designated as SWMU #208. The operation of the pit was approximately from the early 1960s to the early 1970s. The pit was also periodically burned as was customary for the time period. In August 1994 the oil pit was sampled as part of the site RFI program. A report of the investigation was included in Thiokol Propulsion RCRA Facility Investigation Source and Contamination Characterization Phase 1 SWMUs, August 2000 (2000 RFI report). The conclusions of the study were that additional investigation was warranted. In May 2017, after discussions with the Division, an effort was made to precisely locate the pit that had been previously covered with about a foot of soil. With Division of Waste Management and Radiation Control representative Jeff Vandel present, a backhoe was used to pull back the soil until the visible dark surface soil layer was found and the pit boundary was determined. Two soil samples were collected at that time of the approximately 3 inch wide dark soil layer from two locations and submitted for VOC and semi-volatile analysis. The results from these samples is found in Table 1. These results show that in this assumed worst case dark layer of soil that there are two primary hazardous constituents, hexachlorobutadiene and trichloroethylene. Of these two only hexachlorobutadiene had a value that exceeds a residential RSL. Hexachlorobutadiene is a known constituent of hydraulic oil and according to an ATSDR reference is readily broken down in soil.

Plant 3 Well 3A Treatment Summary Reports The treatment system at the Promontory Plant 3 well 3A has been monitored quarterly according to the UDWMRC approved plan. The plan includes a request that a summary of the previous year to date monitoring data be included in the September Semi-Annual report. This summary is found in Table 1. The treatment system removes TCE to below the 5p/L health based limit with a carbon replacement interval of every 6 + months. Water usage at Plant 3 has diminished with lower production. Therefore, ATK is finding that TCE removal extends significantly beyond the initial 6 month carbon replacement interval. During this sampling period the M-53 environmental laboratory experienced breakdowns of the gas chromatograph and the March sample went out of hold time. Samples were resent sent to Chemtech Ford for VOC analysis however a labeling error resulted in no value being reported for TCE from the second quarter sampling. The third quarter VOC sampling was collected earlier in May to avoid similar issues. In addition, perchlorate removal in the two septic tanks, M-201 and M-205, is being monitored for effectiveness. Samples showed some perchlorate detections in M-201 or M-205. These samples are collected from the septic tanks where biological treatment is in process and where conditions are present to remove perchlorate. The detections and subsequent non-detects demonstrate treatment is taking place. However, ATK is reevaluating the sampling rational and would like to discuss options with UDWMRC. Ways to optimize removal conditions in the septic tanks are also being determined.

This SWMU is related to a former photographic X-ray development process at building M-19A that historically discharged photographic fixer waste water to a storm drainage channel. Using an approved plan from the UDWMRC and with Jeff Vandel at the site, soil samples were collected within the drainage channel. Samples were collected from the surface to three feet in depth and screened in the field with an XRF. The highest values were then analyzed using standard EPA laboratory methods. These samples showed that the values within the drainage channel were below the EPA Regional Screening Level (RSLs) for residential exposure. The constituents of concern were silver, cadmium, chromium and Cr (VI). However a change to the sampling plan was made in the field and samples were also collected along the banks of the channel which showed that two locations had higher concentrations of Cr (VI). Additional samples were later collected to characterize these two sites. Based on these results some soil removal will be needed at the two locations. A separate report has been submitted to UDWMRC with additional details and a request to conduct the removal. Figure 1 shows the results of the sampling at SWMU 553.

Summaries of All Findings The summaries of the corrective action work conducted on SWMUs during this reporting period are found in section 1 above. 3. Summaries of All Problems or Potential Problems Encountered During the Reporting Period There were no significant problems encountered during the reporting period. 4. Actions Taken to Rectify Problems No problems were identified. 5. Projected Work for the Next Reporting Period Monitoring the P-10 well and the Plant 3 Well 3A treatment system will be ongoing through the next reporting period. Additional work at SWMU #553 at building M-19A and SWMU #201 at M-136 will be conducted. There will be continuing work with UDWMRC in investigating and closing other SWMUs currently under review.
