ATK and its predecessors have been primarily involved in the research, testing and production of rocket motor propellants. The manufacturing processes at ATK - Promontory include the preparation and mixing of high-energy ingredients, casting and curing of the propellant formulations, assembly of rocket motor segments and military flares, and quality control testing of finished products. These activities have included the production and testing of motors for the Space Shuttle, the wash-out and reloading of Minuternan ICBMs, and many other projects for the Department of Defense (DOD). The ATK facility is a 20,000 acre site that is remotely located in Box Elder County, approximately 30 miles northwest of Brigham City, Utah. The ATK plant is divided into four major areas designated as: Defense and Launch Vehicle (DLV), Administrative and Manufacturing Area (or Space), Test Area, and High Performance Propellant Development Area (or Plant III). There are approximately 675 buildings located on the four areas that comprise the ATK plant. The closest inhabitants to the facility live approximately one mile to the west of the adminishation area on a cattle ranch. Currently, ATK's primary activities consist of: military flare production; work on the next generation of the Space Launch System, 5 segment solid rocket motor; restoration of stages one and two of Minuteman motors; destruction of third stage Minuteman motors by open burning; rocket motor casing work for Castor, GEM 40 and GEM 60 motors and production work on Trident D-5 motor nozzles. Facilitv Backsround/Source of Groundwater Contamination In June of 1986, ATK was issued a Notice of Violation for operating surface impoundments without interim status or an approved plan. ATK was disposing of wastewaters and solvents contaminated with propellant in unlined pits at the M-136 Open Bum Grounds. ATK has estimated that approximately 175,000 gallons of wastewater were disposed of per month from 1962 to 1986. Other source areas that existed at the facility include historic drain fields and releases from industrial processes. These practices resulted in the contamination of the regional and perched groundwater aquifers that underlie the facility. Requirements to address violations associated with these pits, or land disposal units, were established in a 1987 Consent Order. ATK closed these units, in accordance with its approved Closure Plan, in May of 1992. A Post-Closure Permit (the Permit) was issued by the Executive Secretary of the Utah Solid andHazardous Waste Control Board on September l,1992, and reissued on September 20,2007. Conditions for groundwater monitoring and corrective action are established in the Permit. Groundwater Monitoring ATK has been conducting semiannual groundwater monitoring at the Promontory facility since 1987. The groundwater protection standard established in the Permit has been exceeded in the compliance wells and contaminants have migrated down-gradient beyond the facility boundary. The primary contaminants that have been detected in groundwater are: TCE, TCA (and their daughter products) and perchlorate. ATK has installed approximately 95 wells since 1987 in order to define the extent of contamination. Based on groundwater monitoring results, it appears that two separate contaminant plumes exist in the regional aquifer in addition to the primary regional plume. Groundwater contamination has also been detected in a perched aquifer zone east of the primary plume in the regional aquifer. Currently, ATK primarily collects water samples using the HydraSleeve, no purge sampling method. As discussed in the 201I O&M Report, the Division approved the use of this sampling method in June, 2008 after ATK completed a study that compared results for samples collected using the conventional, purglng method with sample results obtained by using theHydraSleeve method. In 2008, the Division requested that ATK evaluate the condition of wells containing stainless steel screens since corrosion of dedicated, submersible, stainless steel pumps was observed as they were removed from wells after they quit working. Furthermore, since ATK was switching from a purglng sampling method to the HydraSleeve method, it was thought that the condition of the well screen was an important factor for ensuring unobstructed flow of groundwater through the well screen and for obtaining representative samples. WelI Screen Corrosion Investisation ATK submitted the Coruosion Investigation Reportfur Monitoring Well Screens at ATK Promontory in May, 2013. ATK investigated six wells for the report by using a down-hole qlmera to view the extent of corrosion. The wells that were evaluated were: D-6, A-10, B-4, E-6, F-3 andLF-2. Video of the well investigation was provided on DVDs that were submitted with the report. In the videos, some areas of the well screens appear to be clogged and cauliflower-like growths can be seen on the screen walls. ATK believes that these growths are iron bacteria. They are mainly observed at the joint between the screen and the PVC pipe (see Photo 4 below). For this report, these growths, and clogging of well screen slots is referred to as corrosion. Determining the degree of well screen corrosion based on observing the videos is subjective. ln addition, the down-hole camera provided images looking directly down the well rather than looking directly at the wall of the screen. This made it difEcult to determine how clear the slots in the screen were, but the general degree of corrosion could be observed. Based on these observations, it appears that moderate to heavy corrosion exists at intervals in wells E-6 and F-3. The 88 to 104 foot interval (out of a 20 ft. screen) in the well F-3 screen appears to be clogged. The screen in well E-6 has moderate to heavy corrosion in the 68 to 72 foot interval (out of a 20 ft. screen). Well D-6 was clear since it contains a PVC screen. The other wells that were investigated (A-10, B-4 and LF-2) had intervals of minor corrosion with spots that appeared more moderate in degree of corrosion. After this initial investigation of the well screens, ATK decided to upgrade its down-hole camera so that the wall of the screen could be observed. The new qlmera has the ability to look both directly down the well and directly at the wall of the well. In August, 2014, Jon Parry and I visited the Promontory facility to observe the investigation of wells B-6, B-7, and E-6 using the new camera. Based on this investigation, approximately 70Yo of well 8-6 is clogged. As shown in Photo 2 below, the slots in the screen are not visible. Well B-7 is mostly clear, but has a three foot interval of corrosion. Well E-6 appears less corroded using the upgraded camera than in the previous investigation, although spotty corrosion is apparerrt in the top two to three feet in the screen. 4 Photo 1 - Well 8-6, photo shows visible screen slots at a depth of 105.3 ft.

Installation of Monitorine Well P-10 A new monitoring well, P-10, was drilled and completed in March, 2012. This well was installed northwest of well P-6 and Building M-585 in the Defense and Launch Vehicle (DLV) Plant (see Figure I ). The primary objective for the new well was to provide a third potentiometric surface point (in addition to wells P-6 and P-7) to help determine the direction of groundwater flow in the perched aquifer below Building M-585. This information was needed to help assess the investigation of three SWMUs associated with this building. In addition, TCE has been detected in well P-6 and TCE and perchlorate has been detected in well P-7. Groundwater was intercepted during the drilling of the well at an elevation of 4,445 feet - 94 feet below the ground surface. The total depth of the well is 105 feet. Based on the groundwater elevations of wells P-6,P-7 and P-l0, it appears that groundwater flow is to the east, northeast. However, ATK has reported that after the well was completed, and a sample was collected, the well went dry. ATK has tried on several occasions since then to get a groundwater elevation at the well, but it is only damp and muddy at the bottom. I - Location of New Moni Well P-10 in the DLV orth Area TCE was detected in the sample collected from well P-l0 at 9.5 nglL (J-flagged). Perchlorate was not detected in the sample. In June, 2014, ATK collected a sample from well P-10 using a passive diffusion bag since there wasn't enough water in the well to collect a sample. TCE was detected in this sample at 185 ug/L. ATK submittod a Well Completion Report for Well P-10 on June 13, 2012. The report contains information on the pu{pose for the well, well construction, well development, geology and a well 1og. The driller's daily logs and the initial analyical results are also included in the report. The status of this well and the SWMUs associated with Building M-585 will continue to be assessed by the Division. Total Depth Measurements of Monitoring Wells ATK is required by its Post-Closure Permit to measure the total depth of all groundwater monitoring wells that are completed in unconsolidated sediments, every three years. Measuring the depth of these wells is required in order to determine if sediment is accumulating in the well which may affect the function of the well screen. ATK measured these well depths in 2013. Table 1 below shows the depths measured in20l3 compared to the total depths that were Table 1 - Total Depth of Monitoring Wells Completed in Unconsolidated Sediments - 2013 Well Total Depth When Well Was Completed Total Depth 2013 Well Total Depth When Well Was Completed Total Depth 2013 A-7 242 (1987)241.50 P-1 257 (as of2008)256.71 B-5 r76 (1e8e)t77.60 P-2 178 (as of2008)178.30 B-6 t27 (re8e)12s.60 P-5 r27 (reer)t26.51 B-7 97 (le8e)97.75 P-8 r79 (19et)179.20 B-8 110 (1e8e)112.90 P-9 1e3 (1991)t92.50 c-7 108 (1e88)t07.20 H-l 47 (2002)45.88 E-l 126 (ree})t2s.60 H-2 s6 (2002)58.25 E-2 l20 (1990)120.80 H-3r 82 (2003)79.95 E-4 r32 (1990)131.80 H-4 r01 (2003)102.01 E-5 r22 (ree})r20.71 H-5 48 (2003)48.25 E-8 228 (ree})225.80 H-6 s0 (2003)53.65 E-9 234 (ree0)233.20 H-gt lso (2003)140.30 F-1 r07 (ree2)106.21 H-gt 2s (2003) l2 (as of2008)t2.20 F-2A'1s3 (1991) 1s0 (2008)141.10 H-10 30 (2003)28.30 F-2BI 2r7 (leer) 2t1 (2008\206.80 J-1 t 148 (2004)145.12 F-2CI 322 (reer) 319 (2008)310.50 J-3r r49 (2004)147.25 F-3 r08 (1ee2)107.60 EW-62 206 (as of2008)263.t5 G-1 e7 (ree6)97.70 M508-t 203 (as of2008)202.40 G-2 e8 (1ee6)98.20 M508-2 199 (as of2008)r 99.38 G-3 26 (19e6)26.57 Ms08-3 202 (as of 2008)202.30 G-4 76 (1ee6)76.40 M508-4 200 (as of2008)200.60 LF-1 136 (as of2008)136.80 M508-81 182 (as of2008)l 81 .73 LF-21 153 (as of2008)r49.t0 TCCl 214 (as of2008)214.0s LF-3 148 (as of2008)148.10 t It uppears that silting in these wells may be an issue. ' Not a completed monitoring well. measured when the wells were completed. Based on these measurements, it appears silting may be an issue in the wells identified in the table. As shown in the table, the F-2 nested wells have total depths measured in 2013 that are approximately l0 feet less than the depths measured in 1991. ATK will be asked to check into the accuracy of these depths. On the other hand, wells that appear to have significant silting, and are marked as such in the Table, show an approximate difference of up to 3 feet in depth (e.g. well J-l had a depth of 148 feet when it was completed, and a depth of 145.1 feet in 2013). It was also observed that the list of wells that are completed in unconsolidated sediments (and are measured for depth every three years) is not consistent. Attachment 3 of the Post-Closure Permit contains a table that lists the wells that should be measured, but some of the wells that are listed haven't been measured in the past, while some wells that aren't on the list have been measured. The list of wells in the Permit needs to be reviewed and modified if necessary. ATK will then be expected to measure all of the wells on the list as required by the Permit. In addition, due to poor well logs and spotty records for some wells, the original well depths are unknown. Original well depths for the wells that are measured also need to be established. OA/OC Data for Groundwater Monitorine Anal*ical Results The Groundwater Monitoring Module of ATK's Post-Closure Permit requires that ATK submit a QA/QC data summary with each Semi-Annual Report. The Permit states that the QA/QC Summary shall be submitted in accordance with the QAPP contained in Attachment 3 of the Permit. After reviewing the QAPP, it is unclear what QA/QC information should be included in the data sufirmary. Based on a review of Semi-Annual Reports for the last few years, it appears that data summaries are not being submitted. The results of trip and field blanks, and surrogate recoveries are reported but MS/MSD recovery results are not reported. In addition, a laboratory control sample results sufirmary and sample extraction and analysis dates and times are also not currently reported. The Division needs to work with ATK to determine what information should be included in QA/QC data summaries that will be submitted with the Groundwater Monitoring Reports. This is an issue that is under discussion with the ATK Bacchus facility as well. Split Samples for Well H-4. Shoteun Sprine and Pipe Sprine In May, 2014,I visited the Promontory facility to collect split samples at Pipe Spring, Shotgun Spring and well H-4. Water samples were collected from these three sources for VOC and perchlorate analyses. Samples were collected from the springs by just dipping the sample bottles into the spring pools near the source of the spring. Samples were collected from well H-4 using a HydraSleeve sampler (see Photo #5). The samples I collected were analyzedby the Utah Department of Health Unified State Laboratory. The results of these samples are compared with the ATK laboratoryresults in Table 2 below.

No obvious discrepancy exists in this limited data set. The springs were selected to sample because they are a potential exposure point - mainly to ecological receptors. Well H-4 was selected because an increasing trend in perchlorate has been observed in this well and it appears that a portion of the regional groundwater plume may split off in the vicinity of this well and flow southwest rather than southeast. Perchlorate concentrations are also going up in Pipe Spring, as expected and predicted by the solute transport model. Graphs of perchlorate concentrations in well H-4 and the springs are shown in Figures 2 and 3 below. The other predominant contaminant that has been observed at Promontory, TCE, is typically detected in both springs at less than 10 ug/L. Since 2008, TCE has either not been detected in well H-4 or it has been detected at less than 10 ue/L.

Based on the investigation ATK has conducted on well screen corrosion, it appears that this is an issue that may impact the function of an unknown number of wells. Out of the eight well screens that ATK has investigated with a down-hole camera, at least one (well 8-6) appears to be heavily corroded. Corrosion also appears to be significant in well F-3. The extent of corrosion, and the degree to which it impacts the function of the well is subjective, however, the corrosion that can be seen in well 8-6 is likely to impact the function of the well. Post-Closure Permit condition IV.D.1.b. states that existing monitoring wells shall be maintained in a fully operational condition for the duration of the Permit. It is apparent that all of the wells at Promontory that contain stainless steel screens should be investigated with the down-hole camera. Wells that have severe corrosion apparent, like well 8-6, should be scrubbed, or redeveloped as needed to remove the corrosion. The Division will continue to work with ATK on this issue. 2. ATK is required to measure the total well depths of all wells at the facility - that are completed in unconsolidated sediments - every three years.

In addition, due to poor well logs and spotty records for some wells, the original well depths are unknown for some wells. The Division will work with ATK to review the list of wells in Attachment 3 and determine if changes should be made to the list. The original well depths for the wells that are measured should also be established and added to the list of wells. ATK is not submitting QA/QC data summaries with the Semi-Annual Groundwater Monitoring Reports as required. The Permit states that the QA/QC Summary shall be submitted in accordance with the QAPP contained in Attachment 3 of the Permit. After reviewing the QAPP, it is unclear what QA/QC information should be included in the data summary. The Division will work with ATK to determine what information should be included in QA/QC data summaries that will be submitted with the Groundwater Monitoring Reports. This is an issue that is under discussion with the ATK Bacchus facility as well. An increasing trend in perchlorate concentration has been observed in well H-4 since 2007. In addition, it appears that aportion of the regional groundwater plume may split off in the vicinity of well H-4 and flow southwest beyond the well rather than southeast. An additional well down-gradient of well H-4 appears to be needed in order to determine the extent of contamination in this area. The area where a new well would be needed is on private property. The Division will request that ATK install the new well and will work with ATK to determine an appropriate location. 4. 13
