This Semi‐Annual Operations Report summarizes and evaluates the data associated with the July ‐ December 2021 period of operation of the groundwater remediation systems at DDOU Operable Unit 4 (OU4) in Ogden, Utah. This report presents data generated from 1 July 2021 through 31 December 2021 at the OU4 and OU4 Hotspot (OU4HS) groundwater remediation systems and data from two OU4 semi‐annual compliance sampling and groundwater elevation monitoring events conducted 19 July through 27 July 2021 and 2 December through 16 December 2021. The summer semi‐annual monitoring event at OU4 typically occurs in June; however, due to contractual issues no sampling was conducted in 2020, and the 2021 event was delayed until July. The July 2021 event was performed prior to the systems being returned to operation after they had been shut down for approximately 1 year and 5 months due to contractual issues. The December 2021 event was performed after the system had been returned to operation. 1.1 Project Background The former DDOU is located in Weber County at 500 West 12th Street Ogden, Utah and covers 1,139 acres within the Great Salt Lake Valley. Defense Logistics Agency, an agency of the Department of Defense (DoD), historically used the DDOU facilities as a supply installation. The facility stored, maintained, and issued non‐ordnance supplies including petroleum products, industrial and commercial chemicals, and pressurized gases beginning in 1941. The DDOU site was transferred to Ogden City under the Base Realignment and Closure program in 2003 and has been renamed the Business Depot Ogden. The site has undergone rapid large‐scale redevelopment and currently contains approximately 9.5 million square feet of industrial and office space. Until the late 1970s, liquid and solid materials were disposed of onsite. Oily liquid materials and combustible solvents were incinerated in onsite burning pits or trenches, and solid materials were burned and buried onsite or taken offsite for disposal. The site has volatile organic compound (VOC) subsurface impacts as a result of these historical practices, and in 1984 the U.S. Environmental Protection Agency (EPA) proposed DDOU (then known as the Defense Depot Hill, Utah [DDHU]) for inclusion on the Superfund National Priorities List. DDOU was subsequently added to the National Priorities List in 1987, and disposal areas and groundwater contamination at the site were divided into four OUs, including OU4. Regulatory oversight for investigations and remediation activities is provided by EPA Region 8 and the Utah Department of Environmental Quality (UDEQ). Investigation and remediation activities performed at DDOU as part of a Federal Facilities Agreement fall under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980 whose program requirements apply to all non‐fuel sites that originated before 1980. Under this program, a Record of Decision (ROD) is the decision document that establishes the final remedy under CERCLA and allows a site to proceed to cleanup. 1.1.1 Record of Decision The OU4 ROD, which was signed in September 1992, established soil removal and groundwater extraction and treatment as the OU4 remedy (James M. Montgomery [JMM] 1992). The selected remedy for soil contamination at DDOU OU4 was excavation and offsite landfill disposal of approximately 4,500 cubic yards (cy) of soil and debris. Ultimately, approximately 9,300 cy of contaminated soil was excavated and disposed at an offsite commercial hazardous waste facility by August 1994. Excavation of the soil DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 1‐2 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah continued into the saturated zone to remove as much potential groundwater contamination source material as possible. Construction of a groundwater treatment system at the main OU4 plume took place between January 1994 and May 1995 and the system began operation in July 1995. The OU4 groundwater treatment system was designed to extract contaminated groundwater, treat it to remove VOCs and re‐inject the treated groundwater into the shallow aquifer. The OU4 groundwater treatment system originally consisted of 31 groundwater extraction wells, 28 injection wells, two air‐stripping towers, subsurface conveyance pipelines and a groundwater treatment plant. Two additional extraction wells were installed in the source area in 2005. 1.1.2 Record of Decision Amendment During implementation of the original ROD remedy, a localized groundwater contaminant plume and associated source area were discovered beneath and between Buildings 15C and 16C in the southwestern portion of OU4, an area which became known as the OU4HS. The OU4HS source area consisted of multiple former disposal trenches and a former oil pit. At the OU4HS source area, approximately 3,500 cy of contaminated soil were excavated to the extent possible without undermining the adjacent buildings and Oxygen Release Compound (ORC) was applied to the excavation. The OU4HS groundwater treatment system began full‐time operation in April 1999 and was designed to intercept VOC‐contaminated groundwater originating from the OU4HS source area under Buildings 15C and 16C and to serve as a “fail‐safe” to prevent offsite migration. The OU4HS groundwater treatment system originally included an ozone/hydrogen peroxide treatment system along with the still‐existing groundwater extraction trench. The trench extends 300 feet along the western DDOU property boundary and down into an underlying clay layer. The extraction trench contains one sump equipped with two sump pumps designed to alternately pump the captured groundwater. Treatment of the OU4HS groundwater was added to the OU4 remedy along with treatment of OU4HS soils in a 2000 ROD Amendment (Montgomery Watson 2000). The OU4HS treatment system was plagued with operational issues and shutdowns and was extracting very low‐level contamination. In September 2003, the low‐level concentrations permitted the OU4HS treatment system to be bypassed and the extracted groundwater discharged directly to the sanitary sewer according to terms of Central Weber Sewer Improvement District (CWSID) Permit No. UST002. At that point the OU4HS system became a groundwater discharge system. 1.1.3 Explanation of Significant Differences After 16 years of pump‐and‐treat system operation at OU4, and in order to accommodate the significant reduction in plume size and contaminant concentrations during that time, the 2012 Explanation of Significant Differences (ESD) changed the OU4 requirements established by the ROD from extraction, treatment and injection of groundwater to extraction and direct discharge of extracted groundwater to the CWSID sanitary sewer (USACE 2012). The ESD also included an update to the groundwater monitoring plan, reducing the number of wells sampled to 17 total wells (12 for OU4 area, 5 for OU4HS area) and reducing the list of analytes to benzene, cis‐1,2 dichloroethene (DCE) and vinyl chloride (VC). In December 2013 and in compliance with the ESD, the OU4 treatment system was modified to use six extraction wells that discharge directly to the sanitary sewer. Demolition and removal of the unnecessary portions of the OU4 groundwater treatment system was completed in 2014 (AEEC 2016). At that point the OU4 system became a groundwater discharge system. Discharge to the CWSID is authorized under a CWSID sanitary sewer discharge permit (Permit No. UST002), which was last renewed on 5 January 2020 and expires 5 January 2025. The permit requires DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 1‐3 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah effluent sampling at the OU4 and OU4HS systems on a semi‐annual basis and specifies a combined maximum discharge rate of 200 gallons per minute (gpm) for the two systems. Sampling of the OU4 system and OU4HS system effluents has been performed on a semi‐annual basis since January 2015. In March 2015, CWSID authorized changing the OU4 sampling location from the sampling port inside a confined space to a grab sample from the discharge flow at the adjacent manhole. In June 2015, CWSID replaced a sewer line near the OU4HS. One of the hotspot groundwater monitoring wells, HS‐10, was in the construction pathway and was abandoned. In April 2020, regulatory approval was received to abandon monitoring wells JMM‐14R and JMM‐64 based on historical concentration trends at each location and the wells were subsequently abandoned. As of the start of the July ‐ December 2021 reporting period, the number of OU4 monitoring wells was 10 wells and the number of OU4HS monitoring wells was 4 wells, for a total of 14 wells. In March 2020, the OU4 and OU4HS remediation systems were temporarily mothballed as per instruction from the U.S. Army Corps of Engineers (USACE). Both systems were returned to operation on 13 August 2022. 1.1.4 Remedial Action Report In June 2021, a remedial action report (RAR) was completed which evaluated the remedial progress at OU4 and optimized the OU4 groundwater monitoring program. The RAR determined that the remedial action objectives for the OU4HS had been met and recommended closure and abandonment of the OU4HS groundwater discharge system (USACE 2021). The RAR also recommended reducing the footprint of the OU4 groundwater monitoring program to the area around the main OU4 groundwater extraction system, which was not recommended for closure. Specifically, the RAR recommended that all OU4HS monitoring wells (HS‐03, HS‐05, HS‐06, and HS‐08) and nine OU4 monitoring wells (JMM‐07R, JMM‐14R, JMM‐30, JMM‐42D, JMM‐54R, JMM‐57, JMM‐58, JMM‐64, and JMM‐65) be removed from the sampling program and subsequently abandoned. Monitoring wells JMM‐08, JMM‐09 and JMM‐56 plus five OU4 extractions wells (EW‐1, EW‐2, EW‐6, EW‐32, and EW‐33) were recommended to comprise a new groundwater monitoring program for OU4. The RAR was inconsistent about EW‐4 being included in the new groundwater monitoring program, with the RAR recommendations in Section 4.3 excluding EW‐4 from the program and Figure 3 of the RAR including EW‐4 in the program (USACE 2021). Because sampling of EW‐4 is necessary for operational purposes and would be relatively inexpensive to perform in addition to the other wells, EW‐4 will be included in the new groundwater monitoring program going forward. The RAR received regulatory approval in October 2021 and the recommendations will begin to be implemented in the January ‐ June 2022 period of operation. 1.2 Report Objectives The objectives of this semi‐annual report are as follows:  Summarize operational data from the OU4 and OU4HS systems, including system flow rates, volumes discharged, system up‐time, effluent VOC concentrations, operational and maintenance issues, and process observations.  Utilize operational data to evaluate system performance.  Summarize system effluent data collected in December 2021 and groundwater sampling data collected in July and December 2021, including groundwater VOC concentrations in compliance monitoring wells and extraction wells and groundwater elevation data. DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 1‐4 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah  Evaluate groundwater remediation progress utilizing groundwater sampling and monitoring results. To meet the objectives of this report, the following data and information for both OU4 and OU4HS were collected from July through December 2021 and groundwater was sampled in both July and December 2021:  Results of sample analyses including concentrations of contaminants of concern (COCs)  Groundwater elevation data  Volumes of water extracted and discharged to the sanitary sewer at OU4  Volumes of water extracted and discharged to the sanitary sewer at OU4HS  System flow rates  Time spent in operation and system shutdowns  Significant observations made during the July ‐ December 2021 period DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 2‐1 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah 2.0 SAMPLING AND MONITORING PROCEDURES AND RESULTS 2.1 System Effluent Sampling Effluent samples from the OU4 and OU4HS groundwater discharge systems were collected on 2 December 2021. The samples were collected according to procedures described in the DDOU Chemical Data Quality Management Plan (CDQMP; USACE 2004) and the approved Groundwater Monitoring Uniform Federal Policy ‐ Quality Assurance Project Plan Operable Units 04, 04HS, and 01 Defense Depot Hill Ogden, Utah (QAPP; USACE 2019). Each sample was analyzed for VOCs using U.S. Environmental Protection Agency (EPA) Method 624, as required by the CWSID permit. All detection limits (DLs) were below the MCLs for the COCs. Laboratory analytical reports for these sampling events are provided in Appendix A. Table 1 summarizes the concentrations of detectable COCs including benzene, DCE, and VC in the OU4 and OU4HS effluent samples from December 2021. Graphs of the effluent VOC concentrations versus time are included in Appendix B. The plots display concentrations since startup of the OU4 and OU4HS systems. 2.2 Groundwater Sampling Groundwater compliance sampling was performed twice during the July ‐ December 2021 period. Historically, groundwater compliance sampling is performed once during each 6‐month reporting period, typically June and December. However, the June 2021 sampling event was delayed until July 2021 due to contractual issues. Prior to the OU4 and OU4HS groundwater discharge systems being returned to operation, compliance samples were collected from the 14 compliance monitoring wells on 26 July through 27 July 2021. Samples were collected (10 from OU4 and 4 from OU4HS) using the procedures described in the CDQMP (USACE 2004) and the QAPP (USACE 2019). Compliance sampling was conducted again from the 14 compliance monitoring wells on 15 December through 16 December 2021. All compliance locations except for JMM‐42D were sampled using the HydraSleeve sampling method. JMM‐ 42D is an artesian well and is sealed with a cap and valve, so a peristaltic pump was used to facilitate collection of a grab sample following a brief purge. Concentrations of benzene, DCE, and VC detected in the groundwater compliance monitoring wells collected during the July ‐ December 2021 period are presented in Table 2 and shown on Figure 1. Graphs of the VOC concentrations versus time for each well are included in Appendix B. For the July 2021 sampling event, VC concentrations were below the VC MCL of 2.0 µg/L in all of the compliance monitoring wells except for HS‐03, which had a concentration of 6.6 µg/L. HS‐03 is located adjacent to the OU4HS soil source area. All benzene and DCE concentrations were below their respective MCLs. For the December 2021 sampling event, VC concentrations were below the VC MCL of 2.0 µg/L in all of the compliance monitoring wells except for HS‐03 (4.1 µg/L, 4.2 µg/L in field duplicate [FD]) and JMM‐54R (2.8 µg/L, 2.7 µg/L in FD). All benzene and DCE concentrations were below their respective MCLs. Sampling of the six extraction wells was performed on 2 December 2021. The extraction wells were purged for 5 minutes prior to collecting a grab sample via a dedicated sample port. Concentrations of benzene, DCE, and VC detected in the extraction wells collected in December 2021 are presented in Table 2 and shown on Figure 1. All extraction wells except for EW‐04 had VC concentrations above the VC MCL of 2 µg/L. The highest VC concentration was in EW‐32 (24 µg/L). EW‐02 had a benzene concentration of 6.1 µg/L, which was above the benzene MCL of 5 µg/L; all other extraction wells had concentrations below the benzene MCL. DCE concentrations were below the DCE MCL of 70 µg/L at all extraction wells. DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 2‐2 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah 2.3 Chemical Data Quality Control The laboratory data from the groundwater sampling events in July and December 2021 were reviewed to evaluate compliance with quality assurance (QA)/quality control (QC) criteria specified in the approved Groundwater Monitoring Uniform Federal Policy ‐ Quality Assurance Project Plan Operable Units 04, 04HS, and 01 Defense Depot Hill Ogden, Utah (QAPP; USACE 2019). The data were reviewed based on precision, accuracy, representativeness, completeness, comparability, and sensitivity. A detailed Quality Control Summary Report (QCSR) presenting the findings of the data review and any potential usability issues is included in Appendix C. EMAX Laboratories, Inc. (EMAX) in Torrance, CA was the primary laboratory for this project. However, EMAX subcontracted all samples for the July 2021 event to Eurofins TestAmerica Denver (TAMQ) when EMAX temporarily shut down in order to move the laboratory to another building. EMAX and TAMQ hold current State of Utah certification under the National Environmental Laboratories Accreditation Conference (NELAC) and Department of Defense (DoD) Environmental Laboratory Accreditation Program (ELAP) certifications for all requested analyses, and chemical analyses for all parameters were performed in accordance with the DoD Quality Systems Manual for Environmental Laboratories, Version 5.3 (QSM; DoD 2019b). Samples were prepared and analyzed in accordance with analytical methods specified in Test Methods for Evaluating Solid Waste SW‐846 (U.S. EPA 2015) and laboratory standard operating procedures. As previously noted, the MCLs are 2 µg/L for VC, 5 µg/L for benzene and 70 µg/L for DCE. The DoD QSM quantitation requirements for the MCLs were met for all samples. EMAX and TAMQ reported positive sample results to the DL. All samples were extracted and/or analyzed within the recommended holding times and were properly preserved for the analytical procedures used for this project. No results were rejected, and all results are considered usable. The overall project completeness for this event is 100 percent (%). Qualified data are considered acceptable for use with the limitations discussed within the QCSR regarding the qualifiers applied to the results. The following summarizes the results of the QC measurements and discusses the effect of non‐compliant QC results on the associated field samples. Field sample results qualified due to non‐compliant QC results are provided in Attachment C‐2 of Appendix C.  E624 analytes 1,1‐dichloroethene, bromomethane, and chloroethane were recovered less than the lower control limit in the continuing calibration verification (CCV) standard for SDG 21L029. The associated non‐detected results in samples OU4‐EFF‐12022021, OU4‐HS‐EFF‐12022021, and trip blank TB‐20211202‐09 were qualified UJ for estimated potential low bias. A review of the July ‐ December 2021 data compared to historical results, as presented in Appendix B, and a review of the QCSR, presented in Appendix C, concludes there are no use limitations on the data collected during this reporting period. 2.4 Physical and Chemical Parameters During the July and December 2021 sampling events, the 14 semi‐annual compliance wells (13 wells in the shallow unconfined aquifer and one well in the deeper confined aquifer) were field tested for the following physical and chemical parameters: pH, conductivity, temperature, turbidity, oxidation/reduction potential (ORP), and dissolved oxygen (DO). Sampling logs and field data sheets are contained in Appendix D. The physical and chemical parameters are summarized in Table 3. DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 2‐3 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah In the 13 groundwater monitoring wells in the shallow unconfined aquifer the physical and chemical parameters were consistent with historical values for pH, temperature, conductivity, turbidity, ORP, and DO. For the July 2021 sampling, the pH ranged from 6.60 to 7.50 (JMM‐08 and HS‐03, respectively). Temperature was between 23.88 to 39.10 degrees Celsius (°C) (HS‐05 and HS‐03, respectively). Conductivity was between 688.64 to 2080.60 micromhos per centimeter (μmhos/cm) (JMM‐30 and JMM 07R, respectively). Turbidity ranged from 3.61 to 122.12 nephelometric turbidity units (NTUs) (HS‐03 and JMM‐07R, respectively). ORP values ranged from ‐221.10 to 27.60 millivolts (mV) (HS‐03 and JMM‐65, respectively). DO values ranged from 0.87 to 3.02 milligrams per liter (mg/L) (HS‐05 and HS‐06, respectively). For the December 2021 sampling, the pH ranged from 6.72 to 8.81 (HS‐05 and HS‐08, respectively). Temperature was between 6.68 to 15.19 °C (HS‐05 and JMM‐65, respectively). Conductivity was between 546.77 to 2100.10 μmhos/cm (JMM‐30 and JMM 07R, respectively). Turbidity ranged from 0.13 to 307.33 NTUs (JMM‐58 and HS‐05, respectively). ORP values ranged from ‐17.70 to 247.00 mV (HS‐06 and JMM 09, respectively). DO values ranged from 1.28 to 5.28 mg/L (HS‐06 and HS‐05, respectively). The well screen of JMM–42D is located in the uncontaminated confined aquifer that underlies the contaminated unconfined shallow aquifer containing the OU4 and OU4HS plume. Historically, JMM‐42D has had a significantly higher conductivity than the wells in the shallow aquifer, providing evidence of continuing separation between the two aquifers. The conductivity at JMM‐42D was 4384.3 μmhos/cm in July 2021 and 4289.6 μ mhos/cm in December 2021. The well with the next highest conductivity was JMM‐ 07R with 2080.6 μmhos/cm in July 2021 and 2100.1 μmhos/cm in December 2021. This indicates that the deeper confined aquifer continues to be separate from the contaminated shallow aquifer. 2.5 Groundwater Elevation Monitoring Depth to groundwater was measured in all 13 groundwater monitoring wells in the shallow unconfined aquifer (9 wells from the OU4 system and 4 wells from the OU4HS system) in conjunction with the July and December sampling events. Measurements were collected on 19‐20 July 2021 and again on 15‐16 December 2021. Deep well JMM‐42D is not gauged or used for the development of site groundwater contours. The well is located in the deep aquifer and is sealed with a cap and valve. JMM‐42D is typically artesian with sufficient pressure to produce above‐surface flow. JMM‐42D had artesian flow when sampled on 27 July 2021 and on 16 December 2021. The upward hydraulic gradient between JMM‐42D and the shallow wells provides additional evidence of hydraulic separation between the shallow and deeper aquifers. Groundwater elevation data for compliance monitoring wells for July 2021 and December 2021 are provided in Table 4a. Groundwater elevation data for extraction wells are presented separately in Table 4b to show the drawdown for each extraction well compared to pre‐operational static levels. Figure 1 presents all groundwater elevation data for both events and depicts a groundwater elevation contour map created from the December 2021 data. To account for turbulent well loss/inefficiency in the extraction wells (the groundwater elevation in an extraction well is typically lower than the groundwater elevation in the immediately adjacent aquifer), an assumed efficiency of 75% was used to adjust the measured drawdown and thus the groundwater elevation at each extraction well for creation of the contours. Given the six‐inch well diameters and low pumping rates, turbulent well loss at the extraction wells is expected to be minimal, and the assumed 75% well efficiency is considered conservative (i.e., not likely to overestimate drawdown). Graphs with groundwater elevations and VOC concentrations versus time are included in Appendix B. DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 2‐4 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah Groundwater elevation monitoring results indicate that the dominant groundwater flow direction during this period was to the south‐southwest toward the Great Salt Lake. Groundwater flow direction was uniform across the site. The average hydraulic gradient across OU4 was 0.0018 foot per foot during July 2021 and 0.0020 foot per foot during December 2021. The gradient was calculated by dividing the groundwater elevation difference between wells HS‐06 and JMM‐07R by the distance between the two wells (3,150 ft). HS‐06 is the downgradient well located on the southwest margin of the treatment area and JMM‐07R is the upgradient well located in the northeastern corner of the treatment area. The groundwater elevation difference between the two wells was 5.78 feet in July 2021 and 6.42 feet in December 2021. Historical hydraulic gradients at OU4 are shown in Table 4c. Hydraulic gradients from July and December 2021 are consistent with historical hydraulic gradients. The average groundwater elevation decreased by 0.90 feet from July 2021 to December 2021. This is consistent with historical trends, where groundwater elevations have fluctuated by approximately 1 foot seasonally with the highest groundwater elevations occurring in the summer and the lowest groundwater elevations occurring in the winter. Contaminant concentrations do not appear to have been affected by the seasonal fluctuations in groundwater elevations. 2.6 Preventative Maintenance Activities No monitoring well issues were identified during the July ‐ December 2021 period. DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 3‐1 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah 3.0 OU4 SYSTEM PERFORMANCE 3.1 Effluent Sampling and Mass Removal The OU4 groundwater discharge system extracts groundwater from six extraction wells and discharges it directly to the CWSID sanitary sewer. In the OU4 effluent sample, the concentration of benzene was 1.3 J µg/L, which is below the benzene MCL of 5.0 μ g/L and below the benzene limit of quantitation (LOQ) of 5.0 μg/L. The DCE concentration in the OU4 effluent sample was 11 µg/L, which is below the MCL of 70 μg/L. The concentration of VC was 9.2 μg/L which demonstrates that groundwater contaminated with VC above the MCL of 2 μg/L is still being extracted from the source area. During the July ‐ December 2021 period, the OU4 groundwater discharge system removed an estimated total of 120 grams (g) of VC, 140 g of DCE, and 20 g of benzene from the groundwater. Contaminant mass removed was calculated based on system flow rates as summarized in Table 5. 3.2 Time Spent In Operation The OU4 groundwater discharge system was operational for a total of 3,258.65 hours during the July ‐ December 2021 period. The system uptime represents 96.7% of the period beginning once the system was brought back online on 13 August 2021 and exceeds the contract requirement for 95% on‐line operation. Table 5 summarizes system performance data, including hours of downtime. 3.3 Volume of Water Processed The calculated gallons of groundwater extracted and discharged from the OU4 groundwater discharge system to the CWSID sanitary sewer during the July ‐ December 2021 period was 3,345,222 gallons. At the conclusion of this period, a calculated cumulative volume of 763,517,553 gallons of groundwater has been extracted at the OU4 system since startup in 1995. 3.4 System Flow Rate The average OU4 system flow rate during the July ‐ December 2021 period was 16.5 gpm. This is below the CWSID maximum of 200 gpm. The average flow rate was calculated by dividing the total volume of water extracted between 13 August 2021 and 31 December 2021 by the total number of hours in that same period. The average, therefore, includes any system downtime that occurred once the system was brought back online after the 1‐year, 5‐month shutdown. The average flow rates for the OU4 groundwater discharge system are summarized in Table 5. 3.5 System Shutdowns Two system shutdowns occurred at the OU4 groundwater discharge system during the July ‐ December 2021 period and four partial shutdowns occurred where one or more extraction wells were offline for a period of time. Downtime that occurred for only one or more individual extraction wells was converted into system downtime as follows: number of hours that a well(s) was down multiplied by n/6, where n is the number of extraction wells that were down and 6 is the total number of extraction wells in the system. Table 6 lists the date, duration, and reason for the shutdown and describes the actions taken to restart the system. Detailed records of each shutdown are maintained on file at the site. DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 3‐2 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah 3.6 Maintenance Activities The preventative maintenance program at the OU4 groundwater discharge system includes regular inspection and cleaning of the extraction well vaults. Other tasks include the cleaning, servicing, or replacement of valves, meters, sensors, pumps, and damaged or aged components on an as‐needed basis. Maintenance records for all equipment and components are maintained on file at the site. Table E‐1 in Appendix E presents a summary of the operation and maintenance activities that occurred at the OU4 site throughout the July ‐ December 2021 period. 3.7 Health and Safety There were no reportable injuries at the OU4 site during the July ‐ December 2021 period. DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 4‐1 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah 4.0 OU4 HOTSPOT SYSTEM PERFORMANCE 4.1 Effluent Sampling and Mass Removal The OU4HS groundwater discharge system extracts groundwater from an extraction trench and discharges the water directly to the CWSID sanitary sewer. Benzene, DCE, and VC were not detected in the OU4HS effluent sample collected during the July ‐ December 2021 period, therefore no contaminant mass was estimated as removed by the OU4HS system. As described in Section 4 of the ESD (USACE 2012), the OU4HS system has historically remained operational as a “fail safe” system to ensure no off‐site migration of contaminants above the MCLs. As per the approved OU4/OU4HS RAR, the OU4HS system is no longer required to act as a “fail safe” to prevent off‐site migration of contaminants (USACE 2021). The system will be shut down in the upcoming January ‐ June 2022 period. 4.2 Time Spent In Operation During the July ‐ December 2021 period, the OU4HS groundwater discharge system was operational for a total of 3,232 hours. The system uptime represents 95.9% of the period beginning once the system was brought back online on 13 August 2021, which meets the performance requirement of 95% for system operation. Refer to Table 5 for a summary of OU4HS system performance data. 4.3 Volume of Water Processed Approximately 2,813,000 gallons of groundwater were extracted and discharged to the sanitary sewer during the July ‐ December 2021 period. At the conclusion of this period, a calculated cumulative volume of 145,033,916 gallons of groundwater has been extracted at the OU4HS system since startup in 1999. 4.4 System Flow Rate The average flow rate for the OU4HS groundwater discharge system was 13.9 gpm during the July ‐ December 2021 period. This meets the minimum target extraction rate of 10 gpm. The average flow rate was calculated by dividing the total volume of water discharged between 13 August 2021 and 31 December 2021 by the total number of hours in that same period. The average, therefore, includes any system downtime that occurred once the system was brought back online after the 1‐year, 5‐month shutdown. Average flow rates for the OU4HS groundwater discharge system are summarized in Table 5. 4.5 System Shutdowns Three system shutdowns occurred during the July ‐ December 2021 period. Table 7 lists the date, duration, and reason for the shutdown and describes the actions taken to restart the system. No scheduled shutdowns occurred during the July ‐ December 2021 period. The OU4HS groundwater discharge system does not have an alarm call out system, so system shutdown times are estimated based on pump operation hours. Detailed records of each shutdown are maintained on file at the site. 4.6 Maintenance Activities Routine corrective and preventative maintenance was performed on system components as recommended by the manufacturers, or more frequently when necessary, based on experience with the system. Typical maintenance activities included cleaning and servicing various system components and DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 4‐2 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah pumps. Maintenance records for all equipment and components are maintained on file at the site. Table E‐2 in Appendix E presents a summary of the operation and maintenance activities that occurred at the OU4HS site throughout the July ‐ December 2021 period. 4.7 Health and Safety There were no reportable injuries at the OU4HS site during the July ‐ December 2021 period. DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 5‐1 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah 5.0 REMEDIATION PROGRESS EVALUATION 5.1 VOC Mass Removal During the July ‐ December 2021 period, approximately 120 g of VC, 140 g of DCE, and 20 g of benzene were removed from the groundwater at the OU4 groundwater discharge system. No COCs were detected at the OU4HS groundwater discharge system and thus the mass removed for each COC was zero for that system. The VOC masses removed for both systems were calculated based on system flow rates and measured contaminant concentrations in the system effluents. Mass removal calculations are summarized in Table 5. Historical mass removal for the OU4 system since July 2004 is presented in Table 8 and displayed in Figure 2. VC mass removed has trended downward for the last 14 years since a high of approximately 3,940 g in December 2007 and has been below 200 g since December 2018. DCE mass removal has trended downward for the last 11 years since a high of approximately 4,670 g in June 2010 and has been below 300 g since December 2018. In general, more DCE mass has been removed from the OU4 system than VC mass. Since the last full semi‐annual period (July‐December 2019), VC mass removal dropped from 180 g to 120 g and DCE mass removal dropped from 290 g to 140 g. This drop in mass removal could be attributed to the fact that the OU4 system wasn’t brought online until forty‐four days into the July‐ December 2021 semi‐annual period. Average flow rates for the OU4 system since July 2004 are also shown in Figure 2. The average system flow rate of 16.5 gpm for the July ‐ December 2021 period is either similar to or greater than the flow for the three periods prior to the shutdown in March 2020. Historical VOC mass removed and average flow rates for the OU4HS system since July 2004 is shown in Table 9 and displayed in Figure 3. VC mass removed has essentially been zero since July 2004 with the exception of two semi‐annual periods where small amounts of VC mass were removed. DCE mass removal fluctuated between zero and 15 g from July 2004 to December 2015 and has been zero since then. In general, much more DCE mass has been removed than VC mass. No mass removal of either COC has occurred from the OU4HS system since January 2016. 5.2 VOC Concentrations in Groundwater VOC concentration data taken from the 14 compliance monitoring wells during the July ‐ December 2021 period are summarized in Table 2. Only two monitoring wells had COC concentrations above their applicable MCLs during the July ‐ December 2021 period: HS‐03 and JMM‐54R. The VC concentrations at HS‐03 were 6.6 µg/L and 4.1 µg/L in July 2021 and December 2021, respectively. Historically the VC concentrations at HS‐03 have been near or below the MCL of 2.0 µg/L with the highest concentration recorded prior to this period at 3.2 µg/L in July 2005 (Figure B‐3). Although the VC concentration at HS‐03 increased to above the MCL, VC does not appear to persist in the aquifer beyond HS‐03 as evidenced by the non‐detect VC concentrations at HS‐08, which is located directly downgradient from HS‐03. HS‐08 VC concentrations were non‐detect in both July 2021 and December 2021 and have been below the VC MCL since June 2007. Evaluation of the geochemical data from HS‐03 indicate that the aquifer environment is reducing in the vicinity of HS‐03 as evidenced by the low DO and negative ORP. The geochemical data from HS‐08 indicate the aquifer environment is more oxidizing in the vicinity of HS‐08 which is more conducive to the degradation of VC. The increase in the VC concentration at HS‐03 could possibly be related to the recent excavation in the former OU4HS source area for water line and storm drain upgrades. Regardless, the increase in VC DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 5‐2 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah concentration at HS‐03 is likely temporary based on historical trends in the data where the concentration increased above the MCL and then dropped off quickly (e.g., the 2.7 µg/L concentration in June 2018 was immediately followed by concentrations below the MCL). Recent trends in ORP and DO at both HS‐03 and HS‐08 indicate that both ORP and DO values are increasing and the aquifer environment is becoming more oxidizing and therefore more conducive to VC degradation. Additionally, the VC concentration at HS‐03 has already decreased from July to December 2021 by 38 percent. The VC concentration at JMM‐54R was non‐detect in July 2021 but increased to 2.8 µg/L in December 2021. The December 2021 VC concentration is the first time that VC has been detected at a concentration above the MCL at JMM‐54R. The shutdown of the OU4 system for 1 year and 5 months may have allowed VC to spread beyond its usual extent. JMM‐54R is located within the zone of influence of the extraction wells near the OU4 source area and any VC in this monitoring well is expected to be captured by the extraction wells. 5.3 Plume Extent The extent of the VOC plume is typically illustrated by creating isoconcentration contour maps. The plume in Figure 1 was created with the December 2021 data and includes 2 µg/L and 20 µg/L isoconcentration contours. In December 2021, VC was detected above the VC MCL of 2 µg/L at HS‐03 and JMM‐54R. VC was also detected above the VC MCL in all extraction wells except for EW‐04. Benzene and DCE were not detected above their respective MCLs at any of the groundwater monitoring wells during the December 2021 sampling so plumes for those COCs have not been depicted. The December 2021 VC plume has two segments delineated by the 2 µg/L contour: the larger main segment in the OU4 source area and the smaller segment surrounding HS‐03. The main segment of the plume is oblong and bean‐shaped and is approximately 630 feet long and 255 feet wide. The smaller segment of the plume exists only in the area surrounding HS‐03. Compared to the last VC plume depiction from December 2019, the extent of 2 µg/L contour in the December 2021 main VC plume has expanded to the north by approximately 100 feet to include JMM‐54R. The extent of the 20 µg/L contour in the main plume segment has lengthened to the south by approximately 250 ft to include EW‐32. The smaller plume segment surrounding HS‐03 did not exist in the December 2019 depiction. 5.4 Hydraulic Control of VOC Plume The groundwater elevation contour map created from the water levels collected in December 2021 (Figure 1) indicates that the groundwater extraction wells at OU4 are affecting groundwater flow patterns in the OU4 source area. Analysis of the flow patterns indicate that the extraction wells are drawing in groundwater from beyond the entire extent of the VC plume and are thus providing hydraulic control of the plume. Direction of groundwater flow displayed on Figure 1 shows groundwater flowing toward the extraction wells in the vicinity of the OU4 source area. The hydraulic gradient in the area of the extraction wells is 0.0334 foot per foot (from JMM‐07R to EW‐06 and using the EW‐06 groundwater elevation at 75% drawdown). The gradient in the area of the extraction wells is nearly 17 times greater than the sitewide gradient of 0.0020 foot per foot, offering additional evidence that the extraction wells at the OU4 system are affecting groundwater flow patterns. Further evidence that shows plume control and optimization of source area extraction is that OU4 system effluent concentrations of all VOC COCs are greater than any monitoring well concentration. DDOU OU4 and OU4 Hotspot Semi‐Annual Operations Report, 1 July 2021 to 31 December 2021 6‐1 Environmental Remediation Tooele Army Depot, Utah and Defense Depot Ogden, Utah 6.0 CONCLUSION 6.1 OU4 Groundwater Discharge System Performance Groundwater contaminated with VC above the MCL of 2 μg/L is still being extracted from the OU4 source area, as evidenced by a concentration of 9.2 μg/L in the OU4 system effluent in December 2021. The OU4 extraction wells also continue to have VC concentrations above the MCL. The OU4 system has been effective at removing mass from the aquifer, although VOC mass removal has been decreasing over time. The average flow rate of the system has decreased over time but remains sufficient to maintain hydraulic control over the plume. The system uptime of 96.7% for the July ‐ December 2021 period exceeds the contract requirement of 95%. The system is operating as intended and it is recommended that the system continue operating as is. 6.2 OU4 Hotspot Groundwater Discharge System Performance Mass removal at the OU4HS groundwater discharge system was zero for each COC during the July ‐ December 2021 period because no COCs were detected in the system effluent. Mass removal has been zero for this system since January 2016. The average flow rate for the OU4HS for the July ‐ December 2021 period was similar to or greater than flows throughout historical operation of the system. The system uptime of 95.9% for the July ‐ December 2021 period meets the contract requirement of 95%. As per the approved OU4/OU4HS RAR, the OU4HS system has met its remedial action objectives and has been recommended for closure and abandonment (USACE 2021). The system will be shut down in the upcoming January ‐ June 2022 period and the recommended abandonment of the OU4HS building and monitoring wells are in the planning stages. 6.3 Remediation Progress Evaluation Two monitoring wells had COC concentrations above their applicable MCLs during the July ‐ December 2021 period: HS‐03 and JMM‐54R. The increase in VC concentration at HS‐03 is not significant because the VC does not appear to persist in the aquifer as evidenced by non‐detect VC concentrations at HS‐08 directly downgradient from HS‐03 and the increase is likely temporary based on historical trends. VC concentrations at monitoring well JMM‐54R may have increased from historical ranges due to the shutdown of the OU4 system for 1 year and 5 months. Any VC concentrations currently at this well are expected to be captured by the extraction wells. The December 2021 groundwater elevation contour map indicates that the groundwater extraction wells at OU4 are affecting groundwater flow patterns in the OU4 source area. Analysis of the flow direction indicates that the extraction wells are drawing in groundwater from beyond the entire extent of the VC plume and are providing hydraulic control of the plume. Based on VC, DCE, and benzene concentrations in the monitoring wells, contamination continues to be contained and isolated in the OU4 source area where the extraction wells are actively extracting contaminated groundwater. All COC concentrations in the monitoring wells, including the anomalously high result of HS‐03, demonstrate the assumptions and conclusions of the RAR, including that VC concentrations degrade in the aquifer between HS‐03 and HS‐08. The decisions set forth in the RAR remain valid and the sampling recommendations to remove multiple wells including HS‐03 and HS‐08 from the optimized monitoring network should be implemented as directed.

JMM-42D is located in the deep aquifer, not the shallow, contaminated aquifer and is not used in the contour analysis. 2. Monitoring well water levels were measured 19-20 Jul 2021 and 15-16 Dec 2021. Extraction well water levels were measured 30 Jul 2021 and 2 Dec 2021. The July water levels are pre-operational (i.e., static). The Dec 2021 water levels were used to create the potentiometric surface contours. 3. The Dec 2021 extraction well groundwater elevations were adjusted to account for well inefficiencies prior to creating contours by using only 75% of drawdown. (Drawdown = static elevation - operational elevation.) 4. Monitoring well sampling was conducted 26-27 Jul 2021 and 15-16 Dec 2021. Extraction well sampling was conducted 2 Dec 2021. The Dec analytical results were used to create the vinyl chloride plume. Results are in units of μg/L. 5. JMM-14R and JMM-64 were abandoned.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. REVISION 1 - CREATED 9/1/21 The sample ID for sample number (280-151342-7) was adjusted from "DDOU-07-21-Jmm-54R-HS-11.95" to "DDOU-07-21-Jmm-54R-HS-11.95A" per client instruction on 8/27/21. The sample ID for sample number (280-151342-16) was adjusted from "TB20210721" to "TB20210727" to match the ID on the COC. This sample ID was not caught at the time of login review. RECEIPT The samples were received on 7/30/2021 9:20 AM. Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved and on ice. The temperature of the cooler at receipt was 5.4º C.

Individual Location Tables and Graphs Effluent samples are analyzed using EPA Method 624. Method 624 results were reported using DoD-ELAP criteria. Groundwater Monitoring samples are analyzed using EPA Method 8260C. Method 8260 results were reported using DoD- ELAP criteria, which uses DL, LOD, and LOQ. As of 01 NOV 2017, non-detect analytical results are reported as less than the LOD per DoD Quality Systems Manual. Prior to this, non-detect analytical results were reported as less than the MDL as reported by the laboratory. An apparent increase in the groundwater ND concentrations in samples collected after 01 NOV 2017 are due to the change in reporting to the LOD and not an actual increase in contaminant concentration.

These data have been reviewed to evaluate compliance with QA/QC criteria based on data quality objectives (DQOs) specified in the approved Groundwater Monitoring Uniform Federal Policy – Quality Assurance Project Plan Operable Units 04, 04HS, and 01 Defense Depot Hill Ogden, Utah (USACE, 2019a), hereafter referred to as the QAPP. This quality control summary report (QCSR) includes the report narrative; a sample summary, including all samples collected and submitted to the laboratory for the associated sample delivery group (SDG) in Attachment C‐1; complete analytical results presented in crosstab format in Attachment C‐2; and an evaluation of field duplicates (FD) relative percent differences (RPDs) in Attachment C‐3; and data validation reports in Attachment C‐4. 2.0 DATA VERIFICATION, DATA QUALITY REVIEW, AND QUALIFICATION EMAX Laboratories, Inc. (EMAX) in Torrance, CA was the primary laboratory for this project. However, EMAX subcontracted all samples for the July 2021 event (SDG 280‐151342‐1) to Eurofins TestAmerica Denver (TAMQ) when EMAX temporarily shut down in order to move the laboratory to another building. EMAX and TAMQ hold current State of Utah certification under the National Environmental Laboratories Accreditation Conference (NELAC) and Department of Defense (DoD) Environmental Laboratory Accreditation Program certifications for all requested analyses, and chemical analyses for all parameters were performed in accordance with the DoD Quality Systems Manual (QSM) for Environmental Laboratories, Version 5.3 (DoD 2019b). Samples were prepared and analyzed in accordance with analytical methods specified in Test Methods for Evaluating Solid Waste SW‐846 (U.S. Environmental Protection Agency [EPA] 2015) and laboratory standard operating procedures (SOPs). The data quality review and assessment were performed by an experienced QA chemist at Synectics in Sacramento, CA who is independent of the analytical laboratory. This evaluation included a review of the analytical data including lab and field QC sample results, field and laboratory documentation, and Stage 4 data submittals. At a minimum, the level of review was Stage 2B, with a minimum of 10 percent of the samples collected for the project reviewed at Stage 4. Groundwater analytical results were compared to project action limits (PALs), which were defined as the EPA maximum contaminant level (MCL) and the Central Weber Sewer Improvement District (CWSID) permit levels as shown in Attachment C‐2. All project data were reviewed on an analytical‐batch basis by assessing QC samples and associated field sample results. Data quality review and usability assessment were performed using the QC criteria defined in the QAPP (USACE, 2019a); DoD QSM (DoD 2019b); DoD General Data Validation Guidelines (DoD 2019c); Test Methods for Evaluating Solid Waste SW‐846 (EPA 2015); and the laboratory SOPs, in that order. The following information was reviewed as part of the data quality review and assessment:  Sample handling and chain‐of‐custody (CoC)  Sample preservation and holding time compliance  Field QC samples, including trip blanks (TBs), equipment blanks (EBs), and FDs Appendix B – Chemical Data Quality Report C‐2 Operable Unit 4 and Operable Unit 4 Hotspot Semi‐Annual Operations Report July to December 2021 Defense Depot Ogden, Utah  Laboratory reporting limits, including limits of detection (LODs) and limits of quantitation (LOQs)  Method blanks (MBs)  Laboratory control sample (LCS) and laboratory control sample duplicate (LCSD) recoveries  Surrogate spike recoveries  Matrix spike (MS) and matrix spike duplicate (MSD) recoveries  Initial and continuing calibration summary information  Internal standards performance (gas chromatography/mass spectrometry [GC/MS])  Precision, including RPD values for duplicate analyses  Case narrative review, laboratory flagging review, and other analytical method‐specific criteria The data quality review and assessment identified results requiring qualification and potential effects on data usability based on the measurement performance criteria (MPC) defined in the QAPP. The following MPC were used for this data quality review and assessment:  Precision is a measure of the reproducibility of measurements, which can be used to verify laboratory procedures, determine matrix effect, or sample homogeneity. Precision was measured by the RPD between LCS and LCSDs, MS and MSDs, or primary and FD results.  Accuracy is a measure of the correctness or closeness to the true value. Accuracy was evaluated by reviewing the following elements: calibrations, surrogates, LCS, LCSD, MS, MSD, MBs, relative response factors and relative standard deviations (RSD), tune criteria, second column confirmations, and internal standards.  Representativeness is a measure of the degree to which the samples reflect the site characteristics. Representativeness was measured by reviewing sampling design, sampling procedures, sample documentation, holding times, and preservations.  Completeness is a measure of the amount of valid data obtained compared to the amount that was expected to be obtained under correct, normal conditions. For completeness requirements, valid results were all results not rejected and determined to be usable in the context of the DQOs. Completeness was evaluated for each analytical method for a particular sampling event with respect to each DQO or end data use. The completeness goal is 95 percent (%) for this project.  Comparability is a measure of the confidence with which one data set can be compared to another. The following were reviewed to ensure comparability: use of standard methods for sampling and analysis, reporting in standard units, operating instruments within calibrated ranges, and using standard and comprehensive reporting formats.  Sensitivity is a measure of the ability of a method or instrument to detect the target analyte at the level of interest. The laboratory‐specific limits were evaluated against the project PALs to determine whether the analytical methods and/or laboratory procedures were able to meet the project DQOs. The qualifiers listed in Table 1 were applied to the analytical data set, as appropriate. Appendix B – Chemical Data Quality Report C‐3 Operable Unit 4 and Operable Unit 4 Hotspot Semi‐Annual Operations Report July to December 2021 Defense Depot Ogden, Utah Table 1 Data Qualifiers QUALIFIER DESCRIPTION U The analyte was analyzed for, but not detected, or the analyte was detected in the sample at a concentration less than or equal to five times (10 times for common laboratory contaminants) the blank concentration. J The analyte was positively identified, and the quantitation is an estimation because of discrepancies in meeting certain analyte‐specific QC criteria. Or the analyte was positively identified, but the associated concentration is estimated above the detection limit (DL) and below the LOQ. J+ The analyte is considered an estimated value with a possible high‐bias due to a QC deviation. J‐ The analyte is considered an estimated value with a possible low‐bias due to a QC deviation. UJ The analyte was not detected; however, the result is estimated because of discrepancies in meeting certain analyte‐specific QC criteria. X The sample results were affected by serious deficiencies in the ability to analyze the sample and to meet published method and project QC criteria. The presence or absence of the analyte cannot be substantiated by the data provided. Acceptance or rejection of the data should be decided by the project team, but exclusion of the data is recommended. Notes: For definitions, refer to the Acronyms and Abbreviations section. Qualification was not required in the following circumstances:  Surrogate or MS recoveries were outside QC limits, and dilution of the sample resulted in surrogate or spike dilution to a level beyond quantitation.  MS recoveries were outside QC limits, and the spiked concentration was less than four times that of the parent sample.  An analyte was detected in the associated blank, but there was no detection in the associated sample.  MS/MSD or LCS/LCSD recoveries exceeded upper control limits (UCLs) and there was no detection in the sample(s). Data were considered for rejection on the following grounds:  Initial calibration (per compound) criteria not met  Continuing calibration (per compound) not verified  All non‐detects with the continuing calibration recovery less than control limits  All non‐detects with the LCS recovery less than control limits  Any compound with LCS recovery less than 10%  Missed holding times greater than two times the method‐specified holding time  Surrogate recovery of less than 10% and a dilution factor of 5 or less Data quality exceptions that do not result in qualifications are not discussed in this report. Appendix B – Chemical Data Quality Report C‐4 Operable Unit 4 and Operable Unit 4 Hotspot Semi‐Annual Operations Report July to December 2021 Defense Depot Ogden, Utah 3.0 CHEMICAL DATA QUALITY REVIEW The data verification and QCSR were performed to assess the overall quality and usability of the data collected during the annual groundwater monitoring event. Complete details for the review and evaluation of field samples and associated QC samples are included in this QCSR. During the data quality review, analytical results or recoveries that fell outside acceptance criteria were identified and qualifiers were applied to the results, where appropriate, in accordance with the project QAPP. Qualified results are considered estimated, and whenever possible, direction of potential bias was assigned and effects on usability are discussed. 3.1 Analytical Sample and Field Quality Control Sample Summary A total of 28 primary groundwater samples, 3 FD groundwater samples, and 4 TBs were collected and analyzed in support of project activities. The sample summary table in Attachment C‐1 includes all field samples submitted to the analytical laboratory. The overall project‐required frequency of one FD for every 10 or fewer primary samples, per analyte, per matrix, was met for the semi‐annual groundwater sampling events. MS/MSDs were collected and submitted to the laboratory at the project‐required frequency of one set for every 20 or fewer project samples (5%) and one for every preparatory batch (designated MS/MSD samples were included with each shipment) for the semi‐annual groundwater sampling events. No FD or MS/MSDs were collected during the sampling of the six extraction wells and the two effluent samples do not require the collection of field QC. Historically, no field QC were collected during the extraction well sampling event as the data were not validated or reported and was used internally for system optimization. As a result of historical practices, the field crew inadvertently forgot to collect field QC during the extraction well sampling event. Field QC will be collected from the extraction wells during future sampling events. EBs were not collected as all samples were collected with disposable sampling equipment. A TB was included in each cooler containing samples for volatile organic analysis (i.e. SW8260C and E624). 3.2 Sample Handling and Chain‐of‐Custody The CoC form and the laboratory case narrative were reviewed to assess sample handling procedures that may affect the integrity of the samples and quality of the resulting data. The CoC and cooler receipt form are included in the final laboratory report. Samples were required to be maintained at 0 to 6 degrees Celsius (°C) following collection, during storage, and upon receipt at the laboratory. Samples were packed with frozen gel packs in accordance with the Brice packaging and shipping SOP, BE‐ SOP‐03 Labeling, Packaging, and Shipping Samples. Groundwater samples for SDGs 21L028 and 21L029 were shipped to Torrance, CA via FedEx and were delivered to EMAX. The samples in SDG 21L205 were shipped to Los Angeles, CA via Alaska Air Cargo where they were picked up by EMAX Laboratories personnel and transported to the laboratory in Torrance, CA. The samples in SDG 280‐151342‐1 were shipped to Arvada, CO, via FedEx and were delivered to TAMQ The sample coolers containing the groundwater samples were received with temperature blanks and ambient cooler temperatures between 0 and 6°C. Appendix B – Chemical Data Quality Report C‐5 Operable Unit 4 and Operable Unit 4 Hotspot Semi‐Annual Operations Report July to December 2021 Defense Depot Ogden, Utah For SDG 21L029 there was a difference in the sample ID between the sample label and the CoC. The label had the sample ID listed as OU‐4‐EFF‐12022021 and the CoC had the sample ID as OU4‐EFF‐12022021. The sample on listed on the CoC was correct and was used. The CoC for SDG 280‐151342‐1 contained two samples with a sample ID of DDOU‐07‐21‐Jmm‐54R‐HS‐ 11.95. The project chemist confirmed with the field crew that the second sample ID collected on 07/27/21 at 9:50 a.m. was a FD. The laboratory was contacted and instructed to add the letter “A” to the end of the sample ID to make it unique. The CoC for SDG 21L205 contained a row that was not expanded enough to allow the entire sample ID for sample DDOU‐12‐21‐JMM7R‐HS‐17.5 to be shown. EMAX contacted the project chemist and the sample ID was confirmed with the field crew and then provided to EMAX. 3.3 Sample Preservation and Holding Time Compliance All samples were extracted and/or analyzed within the recommended holding times and were properly preserved for the analytical procedures used for this project. 3.4 Sample Limits of Detection and Limits of Quantitation Sample LOQs and LODs for non‐detects were compared to PALs to determine whether the laboratory data met the MPC for sensitivity. PALs for groundwater analytical results were compared to EPA MCLs and CWSID discharge permit limits, if available. All reported LODs for non‐detect results met project MPC for sensitivity. 3.5 Blanks The following sections describe the results of the review and assessment of data for each analytical method. QC parameters met project MPCs and DoD QSM v.5.3 criteria except where noted. 3.5.1 Method Blanks An MB was included with each preparatory batch of 20 or fewer samples, as required. MB detections are indicative of laboratory cross‐contamination. No target analytes were detected in the MBs. 3.5.2 Trip Blanks A TB was included with each cooler containing volatile samples, as required. TB detections are indicative of shipment and storage cross‐contamination. No target analytes were detected in the TB. 3.6 Laboratory Control Samples An LCS or LCS/LCSD pair was included with each preparatory batch, as required. LCS and LCSD %R and LCS/LCSD RPD were compared to the project MPC. All LCS/LCSD recoveries were within control limits and LCS/LCSD precision was within the RPD limit. Appendix B – Chemical Data Quality Report C‐6 Operable Unit 4 and Operable Unit 4 Hotspot Semi‐Annual Operations Report July to December 2021 Defense Depot Ogden, Utah 3.7 Matrix Spike Samples and Duplicates Project‐specific MS/MSD samples were collected and submitted at the project‐required frequency of one for each preparatory batch and one MS/MSD per 20 or fewer samples. MS and MSD samples were prepared and analyzed for each laboratory batch. MS/MSD recoveries and MS/MSD RPD were compared to project MPCs and met acceptance criteria. 3.8 Surrogates Surrogates were included with all laboratory QC and field samples, as required. Surrogate recoveries were reviewed and compared to project MPC. All surrogate recoveries were within control limits for laboratory QC and field samples. 3.9 Field Duplicate Precision FD precision was evaluated by calculating the RPD between the parent sample result and the FD result when both results were above the LOQ, and when one result fell between the LOD and the LOQ. Acceptance criteria were less than 30% for water results. A total of 3 FD samples were submitted and analyzed for 28 primary groundwater samples (requiring FDs). The FD pairs were analyzed by method SW8260C. Attachment C‐3 summarizes the field duplicate detections that were included in precision evaluations. 3.10 Additional Quality Control Discrepancies E624 analytes 1,1‐dichloroethene, bromomethane, and chloroethane were recovered less than the lower control limit in the continuing calibration verification (CCV) standard for SDG 21L029. The associated non‐ detected results in samples OU4‐EFF‐12022021, OU4‐HS‐EFF‐12022021, and TB TB‐20211202‐09 were qualified UJ for estimated potential low bias. No additional QC items that required data qualification were identified. 4.0 COMPLETENESS Completeness is a measure of the amount of valid data obtained compared with the amount that was expected to be obtained under correct, normal conditions. For completeness requirements, valid results are all results not rejected and determined to be usable in the context of project DQOs. Completeness was evaluated using the formula below. The goal for completeness was 95% for all methods and matrices. % 𝐶𝑜𝑚𝑝𝑙𝑒𝑡𝑒𝑛𝑒𝑠𝑠 ൌ 100 𝑥 ሺ𝑉 𝑛 ሻ Where: V = number of measurements judged valid n = total number of measurements No results were rejected and all results were considered usable. The overall project completeness for this event is 100%. Appendix B – Chemical Data Quality Report C‐7 Operable Unit 4 and Operable Unit 4 Hotspot Semi‐Annual Operations Report July to December 2021 Defense Depot Ogden, Utah 5.0 OVERALL DATA QUALITY AND USABILITY ASSESSMENT The overall quality of the project data was acceptable and completeness goals were met. The most significant issue identified during the data quality review and assessment were the low recoveries of 1,1‐ dichloroethene, bromomethane, and chloroethane in the CCV for method E624 resulting in data qualification as noted in Section 3.10. Qualified data are considered acceptable for use with the limitations discussed within this QA/QC report regarding the qualifiers applied to the results.

This assessment has been made through a combination of automated data review (ADR) and supplemental manual review, the details of which are described below. The approach taken in the review of this data set is consistent with the requirements contained in the TEAD Chemical Data Quality Management Plan 2017, QSM 5.1, Post Closure Permit 2017 and the additional guidance documents incorporated by reference to the extent possible. Where definitive guidance is not provided, results have been evaluated in a conservative manner using professional judgment. Sample collection was managed and directed by Brice Environmental Services Corporation, Salt Lake City, UT; analyses were performed by Eurofins Environment Testing TestAmerica, Arvada, CO and were reported under sample delivery group (SDG) 2801513421. Data have been evaluated electronically based on electronic data deliverables (EDDs) provided by the laboratory, and hard copy data summary forms have also been reviewed during this effort and compared to the automated review output by the reviewers whose signatures appear on the following page. Findings based on the automated data submission and manual data verification processes are detailed in the ADR narrative and throughout this report. All quality control (QC) elements associated with this SDG have been reviewed by a project chemist in accordance with the requirements defined for the project. This review is documented in the attached Data Review Checklists. The QC elements listed below were supported by the electronic deliverable and were evaluated using ADR processes. Results of the ADR process were subsequently reviewed and updated as applicable by the data review chemists identified on the signature page. Quality control elements that were not included in the electronic deliverable were reviewed manually and findings are documented within this report. Summaries of findings and associated qualified results are documented throughout this report. A total of 0 results (0.00%) out of the 64 results (sample and field QC samples) reported are qualified based on review and 0 results (0.00%) have been rejected or deemed a serious deficiency (X qualifier). Trace values, defined as results that are qualified as estimated because they fall between the detection limit and the reporting limit/limit of quantitation, are not counted as qualified results in the above count. The qualified results are detailed throughout this report and discussed in the narrative below, where appropriate.

No issues. 12/20/2021 The system was found down. Multiple system components had failed. There was no indication that a power outage caused the shutdown. No alarms appear to have been triggered. As part of a system check, the system was accessed remotely during the morning and the system indicated no flow from EW- 6. A technician mobilized to the site and just before arrival the entire system went down. The HMI had stopped displaying data from the extraction wells, and the PLC would not stay powered on. The VFD for EW-6 did not show power, and all other VFDs had power but were not operating. The PLC would not stay powered on. 12/21/2021 Was able to get the PLC to stay powered on, however all VFDs failed to communicate with the PLC and HMI. EW-2, EW-4, and EW-33 were restarted in a manual mode which bypassed the PLC and HMI. 12/22/2021 Champion Technology on site to troubleshoot the PLC. The PLC programming had to be re-uploaded to the PLC from a backup version because the programming had been deleted during the system failure. The PLC would not receive information from the VFDs. Was able to restart EW-1 and EW-32 in a manual mode which bypassed the PLC and HMI. 12/23/2021 Replaced VFD at EW-6, but could not get the pump running. Pulled EW-6 pump and motor and found that the wire leads at the motor had severed and had caused an electrical short when they touched the pump. The cause of the exposed wire is not known. The electrical short is believed to be the cause of the operational issues that began on 20 December 2021. 12/24/2021 System check. EWs 1, 2, 4, 32, and 33 are operating well in manual mode. EW-6 still down. 12/26/2021 System check. EWs 1, 2, 4, 32, and 33 are operating well in manual mode. EW-6 still down. 12/27/2021 Tested wiring from VFD to the motor at EW-6; wiring ok. Tested the motor at EW-6 and determined it has failed. Will obtain replacement. EWs 1, 2, 4, 32, and 33 are operating well in manual mode. 12/28/2021 Replaced the pump and motor at EW-6. Removed old splice kit from wiring on motor and replaced with new. Brought EW-6 back on line in a manual mode which bypassed the PLC and HMI. Champion Technology on site to perform further troubleshooting. All EWs running in manual mode. The VFDs at EW-1 and EW-32 will not communicate with provided VFD keypad, indicating issues with them. 12/29/2021 System check. All EWs operating in manual mode. Energy Management on site to troubleshoot VFD/PLC issues. 12/30/2021 System check. All EWs operating in manual mode with total flow rate of 15.6 gpm. 12/31/2021 Collected weekly data. All EWs operating in manual mode with total flow rate of 15.47 gpm. Notes: For definitions, refer to the Acronyms and Abbreviations section.

Turned on main culinary water to the plant to test the backflow preventor, was ok. Turned off water after testing. Performed inventory of the OU4HS system components. 8/10/2021 The OU4 HS building and the extraction vault were cleaned. The flow meter in the extraction vault was disassembled, cleaned, and re-installed. 8/13/2021 Went through pre-startup checklist. Turned on necessary breakers. Verified power to flow meter in extraction vault. Extraction pumps P-1A and P-1B were cycled to inspect for solids. Both pumps functioned normally and no solids were visible. The system was brought online. Tested P-1A and P-1B to ensure they operated well. Pump P-1B placed as lead pump for now. 8/14/2021 System check. No issues. 8/15/2021 System check. No issues. 8/16/2021 The system was found shut down due to a pump failure alarm for P-1B. The system was brought back online using P-1A. Later in the day the system was found shut down due to a pump failure alarm for P- 1A. The cause for the alarms could not be determined and the alarms could not be duplicated while on site. Both pumps were observed to operate normally while in “Hand” mode and each pump produced up to 12 gpm. The system was brought back online with P-1A operating. Estimated downtime was 22 hours. 8/17/2021 System check. No issues. 8/18/2021 System check. No issues. Performed weekly data collection. Switched from P-1A to P-1B. 8/21/2021 System check. No issues. 8/21/2021- 8/23/2021 The system shut down 21-22 August 2021, likely due to power failure as a result of a severe thunderstorm. The system was brought back online on 23 August 2021. Estimated downtime was 36 hours. 8/24/2021 System check in morning found no issues. The system was found down in the afternoon, with both P-1A and P-1B showing a pump failure alarm. Both pumps failed to produce any flow and faulted immediately after attempts to restart. It was determined that both pumps needed to be replaced before the system could be brought back online. 8/25/2021 P-1A and P-1B pumps and motors were pulled and inspected. P-1A had a hole in the galvanized fitting connecting the discharge piping to the pump head. The P-1B pump was fouled and the impeller shaft was difficult to spin. The motors for both P-1A and P-1B were confirmed to function normally. Old broken sandbags were removed from around the extraction vault and disposed of. The rotted wood shoring between the extraction vault and the surrounding asphalt surface was removed and replaced with new shoring. 8/27/2021 New pumps were installed at P-1A and P-1B and the system was brought back on line. During pump installation, the galvanized fitting connecting the discharge piping to the pump head was replaced with a new stainless-steel fitting on both P-1A and P-1B. Estimated downtime was 80 hours. 8/28/2021 System check. No issues. 8/29/2021 System check. No issues. 8/30/2021 System check. No issues. 8/31/2021 System check. No issues. 9/1/2021 System check.

Both FYRs indicated that wastes were set on fire in the OU4 area to provide training for the Depot’s fire department. The presence or absence of PFAS compounds due to possible use of AFFF in addition to the potential waste source areas that remain in place below Buildings 359 (15C) and 367 (16C) has not yet been confirmed. EPA contends that an investigation should be conducted for the potential presence of PFAS and include sampling of the existing groundwater well network to ensure that groundwater is not contaminated with PFAS compounds. EPA’s comments on the Sixth Five-Year Report (August 11, 2022) recommended the Army to include PFAS investigation as an issue or recommendation. Your comment has been submitted to the BRAC Environmental Office for consideration of contracting an investigation of DDOU OU4 for PFAS. The Boyer Company is planning to develop the OU1 and OU4 property beginning in spring of 2023. They have requested that wells within the footprint of new construction be abandoned and new wells drilled if necessary in parking and landscaping areas. Additional groundwater samples can be taken during a PFAS investigation using a hydropunch method. EPA looks forward to scoping the PFAS investigation at DDOU with the Army. Yesterday, 14 Feb 2023, EPA issued relevant guidance entitled “EPA Guidance Clarifying the Use of CERCLA RIs for Scoping Releases and Defining the Nature and Extent of PFAS and other Contamination at Federal Facilities on the NPL” Regarding the proposed construction at this site, further dialogue will be necessary to ensure proper LUC implementiation, the construction does not exacerbate mobilization of contaminants, or present unacceptable risks to human health and the environment. Page 2 of 3 Item # Reviewer Reference Comment Response Backcheck Comments (15 Feb 2023) General Comment #2 EPA N/A In September 2021, EPA approved recommendations for removal of sampling and later abandonment of wells solely associated with OU4 HS based on the data presented in the June 2021 Remedial Action Report. However, groundwater samples collected at HS-03 well since that time in July 2021 and December 2021, indicates that Vinyl Chloride (VC) is exceeding the maximum contaminant level (MCL). Based on these newer data, EPA does not recommend the removal of sampling wells HS-03 and JMM-54R from the monitoring network. Additionally, EPA notes that laboratory samples for HS-03 in July 2021 and December 2021 were conducted at different laboratories, which could have affected the reported levels for VC during the separate events. EPA recommends that these wells continue to be sampled on the current schedule until a modification is approved by EPA and it is clear that the anomalous readings have returned back to previous concentration levels below MCLs and are and continuing to meet site groundwater cleanup standards and MCLs. Concur. Monitoring wells HS-03 and JMM-54R will be included in the monitoiring well network moving forward (starting December 2022). The monitoring wells will remain part of the monitoring well network until statistical analysis confirms that vinyl chloride concentrations have decreased to below MCLs and meet site groundwater cleanup standards. Concur. General Comment #3 EPA N/A EPA requests regulator comments to be included in the document as part of the administrative record for future project planning needs and assessments and documenting both EPA and State involvement. Please include an additional Appendix to the OU4 and OU4HS Semi-Annual Operations Report for regulator comments. Concur. This response to comments (RTC) matrix containing regulator comments will be included in the Final report in a new appendix (Appendix F). Concur. Specific Comment #1 EPA Section 2.2, page 2-1 EPA requests that the report specify within the text what sampling method was used to sample the extraction wells and compliance well JMM-42D. Note that data for sampling this well for future sampling events should be included on a separate field form from the HydraSleeve field form included in Appendix D so that all relevant sampling information can be reviewed. Concur. The first paragraph of Section 2.2 has been updated to specify which sampling method was used to sample JMM-42D and the third paragraph of Section 2.2 has been updated to specify which sampling method was used to sample the extraction wells. For future sampling events, a different field form will be used to document sampling of extraction wells. JMM-42D was removed from the monitoring network per the monitoring well network optimization in the June 2021 Remedial Action Report. Concur. Page 3 of 3 Item # Reviewer Reference Comment Response Backcheck Comments (15 Feb 2023) Specific Comment #2 EPA Section 2.3, page 2-2, and Appendix C, Section 2.0, page C-3. The sections on data quality control indicates that samples in sample delivery group 280-151342-1 were run by a contract laboratory other than EMAX Laboratory, Inc. (EMAX) due to a laboratory shutdown. EPA suggests for clarity purposes that the report text identify that all of the samples for the July 2021 event were submitted to Eurofins TestAmerica Denver (TAMQ). Concur. Section 2.3 of the main report and Section 2.0 of the Quality Control Summary Report in Appendix C were revised to state that all of the samples for the July 2021 event were subcontracted to TestAmerica Denver. Concur. Specific Comment #3 EPA Section 2.5, page 2-3. EPA requests that the section on groundwater elevations include a summary comparison of water levels to previous sampling events and description of any deviations within the report text. Additionally, please specify within the report text if there are any known seasonal affects at any of the wells currently being monitored and if so, how these appear to affect contaminant concentrations. Concur. The following text has been added to Section 2.5: “The average groundwater elevation decreased by 0.90 feet from July 2021 to December 2021. This is consistent with historical trends, where groundwater elevations have fluctuated by approximately 1 foot seasonally with the highest groundwater elevations occurring in the summer and the lowest groundwater elevations occurring in the winter. Contaminant concentrations do not appear to have been affected by the seasonal fluctuations in groundwater elevations.” Concur. Comment #1 DERR Section 5.1 VOC Mass Removal, page 5-1, second paragraph, sixth sentence The sentence states that “This drop in mass removal could be attributed to the fact that the OU4 system wasn’t brought online until forty-four days into the July-December 2022 semi-annual period.” The time frame provided appears to be an error and the time frame corrected from July-December 2022 to July- December 2021. Please review the documents for the OU4 extraction system and provide the correct time frame for when the system was brought online. Concur. The timeframe has been corrected in this sentence from July- December 2022 to July-December 2021. Concur. This page intentionally blank
