Promontory Post Closure Permit. ATK Launch Systems Inc is owned by Northrop Grumman Systems Corporation. The purpose of this SAP is to present methodologies that will be used for investigation and closure of SWMU 233 according to Utah Administrative Code (UAC) R315-101. R315-101 and R315-7-14 (which incorporates 40 CFR 265.114 and 265.197, by reference) which outline the processes necessary to evaluate potential risks and options for closure. Once this SWMU has been characterized, it is anticipated that a risk-based closure under a residential scenario will be selected. The final closure solution for the SWMU will be discussed with the Division of Waste Management and Radiation Control (the Division) as the SWMU has been characterized for contamination from constituents of probable concern (COPC), human-health and ecological risk, and soil to groundwater migration potential. RCRA Facility Investigation Sampling and Analysis Plan SWMU 233 Page | 2 July 2024 2.0 FACILITY DESCRIPTION The following sections discuss the general facility and local conditions around SWMU 233. 2.1 GENERAL DESCRIPTION The Facility is located about 18 miles northwest of the Corinne, Utah, and 14 miles southwest of Tremonton, Utah (Figure 1). The Facility operates as a solid-rocket propulsion research, development, testing, and production facility. Additional information regarding production and waste-handling activities at the Facility are provided in a RCRA Facility Investigation Phase 1 (Phase 1 RFI) of the Promontory Facility prepared for the Utah Division of Solid and Hazardous Waste (2000), now the Division of Waste Management and Radiation Control (the Division). SWMU 233 is located along the south end of the South Plant adjacent to Building M-303. The location of SWMU 233 within the Facility is shown on Figure 2. The location of SWMU 233 was based on the 2000 Phase 1 RFI and Google Earth. 2.2 LOCAL GEOLOGIC CONDITIONS SMWU 233 ranges from approximately 30 to 50 feet above groundwater. SWMU 233 is located on a western flank of the Blue Springs Hills. This area is comprised of horst and graben block fault system with two major fault trends: north15 degrees east and east-west. The Blue Springs Hills at this location consists of Paleozoic carbonate units covered with a thin veneer of Quaternary alluvium. The valley is filled with Tertiary and Quaternary sediments which include older fluvial and lacustrine sediments, alluvial fan deposits, Lake Bonniville sediments, and recent alluvium. SWMU 233 is located on a gentle slope of moderately large alluvial fan. Sediments consist of unconsolidated gravels, sands, and clays of colluvial (debris flow), fluvial, and alluvial depositional environments. Groundwater has a general western gradient within the Blue Springs Hills. However, within the valley, flows are generally south towards the Great Salt Lake. RCRA Facility Investigation Sampling and Analysis Plan SWMU 233 Page | 3 July 2024 3.0 SMWU DESCRIPTIONS SWMU 233 is an abandoned burning ground with approximate dimensions of 700 feet by 300 feet, based on historic photographs, see Figure 3. This burning ground operated from 1959 to 1964 and only burned small quantities of waste daily during those years. During the 2000 Phase 1 RFI ten sample locations with samples collected at 2 feet and 5 feet in depth. During the 2000 Phase 1 RFI NGSC asked for closure of SWMU 233 with no further action. April 5, 2024, the Division sent a letter numbered DSHW-2024-005542. The following concerns were asked to be addressed: 1. The SWMU 233 old burn ground was used for open burning of waste reactive materials consisting primarily of waste propellant, propellant contaminated waste, and potentially waste solvents at the ground surface. Therefore, the highest concentration of constituents related to the open burning activities is likely to be in the surface soils. The RFI Report says samples were collected at the two-foot below ground surface (bgs) and five-foot bgs depths at each location. The surface exposure pathway has not been evaluated. Additionally, most sample locations (eight out of ten) were selected from the center line of the burn trench. The remaining two sample locations were chosen at random. Sample locations at the center of the burn trench may potentially represent the worst-case scenario (and therefore the highest concentrations); however, the extent of lateral contamination has not been delineated. Please conduct additional sampling to characterize surface soil and to define the lateral extent of potential contamination. 2. The RFI Report states that the soil sample analysis was performed by Thiokol’s environmental laboratory using Environmental Protection Agency (EPA)-approved methods but does not list the specific analytical methods used. Please include the analytical methods used to analyze the soil samples in the report. 3. The SWMU 233 RFI Report compares analytical data to EPA Preliminary Remediation Goals from 1999, EPA Proposed RCRA Corrective Action Levels from 1990, United States RCRA Facility Investigation Sampling and Analysis Plan SWMU 233 Page | 4 July 2024 Geological Survey (USGS) Background concentrations of Elements in Soils from 1984, and EPA Soil Screening Levels dilution attenuation factor (DAF) 20 from 1997. The Division acknowledges that the SWMU 233 RFI Report was prepared years ago when these screening levels were current. Please note the following information applies to all current and future investigations: -Analytical data shall be compared to current applicable screening levels. -While the Division acknowledges that soil metals contamination concentrations were historically compared to USGS National Background Ranges, the comparison of soil metals contaminant concentrations to either site-specific or the default county-specific background threshold values for Utah should be conducted, in accordance with the Technical Guide for Risk Assessments: Utah Administrative Code R315-101 (TGRA). -It is appropriate to compare maximum contaminant concentrations to a background threshold value (BTV) (typically the 95% upper tolerance limit derived from the background dataset) or the default county-specific BTV. 4. The RFI Report states that xylene was the only constituent within the area of concern that exceeded the range found in Thiokol (ATK Promontory) background soil. While this appears to be true based on the scatterplots and boxplots provided in the report, the median concentration of xylene appears to be higher than the background xylene concentration. Xylene is also not a naturally occurring compound in the environment. Unless the xylene concentrations detected in the background soils can be attributed to something other than the activities conducted at the ATK Promontory facility, xylene should be retained as a contaminant of potential concern (COPC). Additionally, the cadmium concentrations in the interquartile range (25% to 75%) within SWMU 233 exceeds the concentrations in the background soil interquartile range – even though the highest concentrations were detected in the background soils. In fact, the two interquartile ranges do not overlap, which indicates that the cadmium concentrations in RCRA Facility Investigation Sampling and Analysis Plan SWMU 233 Page | 5 July 2024 SWMU 233 may in fact differ from the background. A quantile-quantile plot may be useful for comparing the two distributions. Please note that any constituent concentrations that are site related must be retained as a COPC, unless they are representative of background. 5. The RFI Report states that the old burn ground was used for open burning of waste reactive materials consisting primarily of waste propellant and propellant contaminated waste and may also have included waste solvents. Based on this information, the constituents of concern have been identified as volatile organics, metals, HMX, and nitroglycerin. However, propellants are commonly mixed with perchlorate containing oxidizers to increase performance. The samples were not analyzed for perchlorate. Please include perchlorate analysis in the analytical suite or provide documentation to show that perchlorate was not treated at this unit. Additionally, open burning of waste explosives and propellant may produce dioxins, furans, and polycyclic aromatic hydrocarbons (PAHs) – depending on the specific characteristics of the waste streams. The samples were not analyzed for these constituents. Please include dioxin/furan and PAH analysis in the analytical suite. 6. The RFI Report states that other organic constituents were reported in low parts-per- billion (ppb) concentrations (<10 grams per kilogram, g/kg) in at least one sample. All results were qualified as estimated as they were less than the reporting limit. Many of the results for these organic chemicals were also qualified as being detected in the laboratory blank. Based on this, the results were not considered to be positive results and were eliminated from further consideration. The data should be included in the RFI Report as qualified rather than simply eliminated from consideration. Please follow the 2018 Quality Assurance Project Plan (QAPP) regarding data evaluation for current investigations. Due to the sites historic use and the Division comments mentioned above, specifically comment 5, United States Environmental Protection Agency (EPA) methods 314.0, 6010, 6021, 7471, 8260,8270, 8280/8290, and 8330 will be used to detect perchlorate, metals, volatiles, semi- RCRA Facility Investigation Sampling and Analysis Plan SWMU 233 Page | 6 July 2024 volatiles (PAHs), dioxins/furan, and nitroglycerin and HMX, respectively. A drawing showing the layout and location of SWMU 233 is shown in Figure 3. A direct push drill unit or backhoe will be used to collect soils samples. Additionally, enough samples will be collected to create a statistically significant mean value of contaminants of potential concern (COPC). The EPA has created a computer model (ProUCL) that allows for calculating a mean value with a 95 percent upper confidence limit (UCL). This model typically uses 16, or more, values to create a 95 percent UCL mean. RCRA Facility Investigation Sampling and Analysis Plan SWMU 233 Page | 7 July 2024 4.0 DATA GENERATION AND ACQUISITION 4.1 SAMPLING PROCESS The objective of sampling the SWMU 233 will be to assess the nature and extent of contamination and exposure point concentrations of the COPC. Eight of the sample locations will be based on the 2000 Phase 1 RFI. These are the locations that were believed to be along the centerline of the burn trench. Three cross trench samples will be collected with the samples collected 20 feet adjacent to the trench and then 40 feet, 80 feet, and 120 feet. The sample locations will be as shown on Figures 3. Some adjustment may be made in the field as needed. 4.2 SAMPLING METHODS Sampling using a direct push rig is anticipated for the site. However, a backhoe may be used as needed. Sampling with a direct push rig will commence by pushing a polyethylene- lined, stainless-steel sample probe to 5 feet in depth. In the event that refusal of the direct push probe is encountered at the selected location, the rig may be moved slightly from the original location if debris or rock cause refusal in the probe advancement. After collection of subsurface samples, the liner will be laid on a table where the site geologist/engineer will visually inspect the collected soils. The sample material remaining in the sleeve. A sample hole will be drilled into the sleeve at approximately 2 feet and 4 feet in depth. A sterile syringe will be used to collect 5 to 10 grams of soils from these drilled holes. This soil will be immediately discharged into a 40 ml VOA with DI and a magnetic stirrer. Acid preservation of soils is not effective as soils at the Facility are alkaline and react with acids. The sleeved will then be cut open, and the top portion and bottom portion of soils will be placed in separate stainless-steel bowls and mixed prior to placement into four-ounce or eight-ounce glass jars as specified by the laboratory. All information collected during the field investigation will be maintained in a field log. Field documentation will consist of the information provided in Section C.5.1.4.2 of the RFI Work Plan QAAP, as appropriate. If a backhoe is used for sampling, a small pit will be dug to expose the subsurface soil. This soil will also be logged and inspected for signs of staining or obvious odors. The soil on the RCRA Facility Investigation Sampling and Analysis Plan SWMU 233 Page | 8 July 2024 pit wall will also be observed for signs of staining. At least three samples will be collected for analysis from each sampling location: one form the surface (0 to 6 inches), one from 1 to 3 feet, and one from 3 to 5 feet. All soil will be examined for visual, olfactory and other observations, such as whether the soil is native or fill, to determine which depth interval is the most likely to be contaminated. If observed, this depth interval will be selected. If the side slopes are too steep or the ground is too soft for a direct push drill unit or backhoe, then a hand auger or bucket auger will be used to collect the samples. The material will be placed in a stainless-steel bowl for compositing. The composite sample will be handled as described in the following section. 4.3 SOIL SAMPLING PROCEDURES Sampling at SWMU 233 will be conducted by collecting soil samples from 0 to 6-inch depth using a stainless-steel spoon or trowel for surface samples only. Where samples that include surface and deeper samples to a depth that non-impacted soils are found will use a bucket auger, direct push unit, or backhoe. A list of constituents to be analyzed along with the analytes method detection limit (MDL), estimated quantitation limit (EQL), and minimum reporting limit (MRL) in Table 1. 4.4 DECONTAMINATION PROCEDURES Prior to and following the collection of each sample, any sampling equipment coming in contact with the soil will be cleaned with a non-phosphate detergent (e.g., Liquinox®), rinsed with tap water, and final rinsed with distilled water. Wastewater generated during field decontamination will be collected and properly disposed. Since direct push technology recovers soils by pushing a sample liner directly into the subsurface, no cuttings will be generated. If hand auguring, auger drilling, or backhoe sampling methods are used, the cuttings generated will remain within the boundary of the respective site. Any portion of the soil not submitted to the laboratory will be logged and either left within the respective site boundary or stored by NGSC. RCRA Facility Investigation Sampling and Analysis Plan SWMU 233 Page | 9 July 2024 4.5 SITE SURVEY CONTROL Following collection of the soil samples, each sample location will be staked or flagged. If needed, then a sub-meter GPS unit or standard survey equipment will be used to record locations. This will allow sample sites to be re-accessed in the future if necessary. 4.6 SAMPLE HANDLING AND CUSTODY Sample containers will consist of glass jars, with Teflon-lined lids, supplied by a laboratory supplier. The sample will be pressed into the jar in a manner that minimizes air pockets. Only decontaminated stainless steel or clean disposable gloves will contact a sample during placement in a bottle. Disposable gloves will be worn at all times during sample handling to prevent cross contamination between samples and skin contract with potential contaminants. These gloves will be disposed of between each sample. Sample bottle will be placed on ice in waterproof chests for delivery to the analytical laboratory. Glass sample bottles will be placed in protective foam or bubble-pack sleeves if needed. All sample bottles will be placed in re-closable plastic bags to provide protection from other samples and sample handlers in the event of sample-container breakage. Sample labels will be used to identify the samples. These labels will be sufficiently durable to remain legible when wet and will be marked with indelible ink and affixed to the sample container. A chain-of-custody form will be completed to trace sample possession from the time of collection through laboratory analysis. One chain-of-custody form will accompany each shipping container of samples. While the samples are in the custody of the collector, they will not be left unattended at locations where the samples may be tampered with. The analyses to be performed will be indicated on the chain-of-custody form, including the quantity and types of containers that comprise each sample. The completed chain-of-custody form will be sealed in a re-closable plastic bag and placed inside the shipping container. The shipping container will then be securely closed and delivered to the analytical laboratory. All filed data will be recorded in a log book. Information to be recorded in the log book will included the date, time, and depth of sample collection, descriptions of the soils encountered RCRA Facility Investigation Sampling and Analysis Plan SWMU 233 Page | 10 July 2024 at each sampling location, reasons for field decisions concerning sample intervals, reasons for departures from prior plans, general observations, etc. 4.7 ANALYTICAL METHODS All soil samples will be analyzed in accordance with EPA Method 314.0, 6010, 6021, 7471, 8260,8270, 8280/8290, and 8330 (see Table 1). This table also includes anticipated method detection limits and method reporting limit or estimated quantitation limits. Unless interferences preclude attainment of the detection limits, the detection limits are sufficiently low to ensure that RSL values can be appropriately evaluated. Constituents will be reported on dry- weight basis. All non-detects will be treated as recommended by the U.S. Environmental Protection Agency ProUCL Model. Samples will be analyzed by the Northrop Grumman Environmental Laboratory at the Promontory Facility (M-53) and Chemtech-Ford (Chemtech) located in Sandy, Utah. A copy of their quality assurance plan is on file and available upon request. 4.8 QUALITY ASSURANCE/QUALITY CONTROL SAMPLES All Quality Assurance/Quality Control (QA/QC) soil samples will be analyzed for the constituents listed in Table1, except as noted below. QA/QC samples will consist of equipment blanks, field duplicates, and trip blanks. 4.8.1 Field Quality Control Samples Equipment Blanks are designed to verify the effectiveness of procedures for cleaning the sampling equipment between individual samples. Several equipment blanks will be collected during the sampling event, following the collection of each field duplicate sample. These blanks will be analyzed for the same constituents as the soil samples-of-record. Equipment Blanks are designed to verify the effectiveness of procedures for cleaning the sampling equipment between individual samples. Several equipment blanks will be collected during the sampling event, following the collection of each field duplicate sample. These blanks will be analyzed for the same constituents as the soil samples-of-record. RCRA Facility Investigation Sampling and Analysis Plan SWMU 233 Page | 11 July 2024 Field Duplicate samples are analyzed to check the reproducibility of sampling and analytical results of samples collected from same location. Field duplicates (representing about 10% of the total samples sent for analysis) will be collected for COPC analysis from randomly- selected locations during the sampling campaign. However, in cases where no or COPC are suspected in the sample field duplicates maybe biased toward locations where COPC will be present. A subsurface sample selected for duplication will be obtained by removing half of the sample following mixing. The duplicate sample will be given a designation that will differentiate the duplicate from the original sample. The field duplicates will be submitted to the laboratory for analyses of the same constituents for which the original sample is being analyzed. All field duplicates will be delivered to the laboratory under chain-of-custody as outlined. Trip Blanks will be included with this investigation. Trip blanks are only used to evaluate the possible contamination from volatile organic compounds (VOCs) during field work or transport of samples. These blanks are then analyzed for VOCs. A trip blank will accompany each sample set that will be analyzed for VOCs. 4.8.2 Laboratory Quality Control Internal laboratory quality control checks will be performed in accordance with best practices. 4.9 DATA MANAGEMENT Field data (e.g.visual observations, lithologic information, etc.) will be recorded in a field log-book. These data will be maintained in project files for future reference. Hard copies of laboratory data will be maintained in project files and will be entered into a Microsoft-based spreadsheet and/or database to aid in evaluation. Electronic data will be stored indefinitely. Hard-copy data will be maintained for a period of at least 3-years. RCRA Facility Investigation Sampling and Analysis Plan SWMU 233 Page | 12 July 2024 5.0 DATA VALIDATION AND USABILITY 5.1 DATA REVIEW, VERIFICATION, AND VALIDATION Data review, verification, and validation will occur as outlined in Section C.5.1 of the RFI Work Plan QAPP (ATK, 2010). All data will be provided to the Division in a searchable Excel format. 5.2 RECONCILIATION WITH USER REQUIREMENTS Data will be reconciled as outlined in Section C.5.2 of the RFI Work Plan QAPP (ATK, 2010). Data that does not meet the accuracy and precision goals as presented will be qualified and flagged. RCRA Facility Investigation Sampling and Analysis Plan SWMU 233 Page | 13 July 2024 6.0 DECISION STATEMENT In accordance with R315-101-6, the decision rule for this site will involve clean closure, corrective action, and/or site management. To provide the information needed to make this decision, the UCL will be calculated for each contaminant identified during sample collection activities, where adequate data is available. Each sampling location will be evaluated individually. Calculation methods and selection of an appropriate UCL will be in accordance with guidelines published by the U.S. Environmental Protection Agency (2016). The data will be evaluated for the COPCs. The Regional Screening Levels (RSLs) for Contaminants of Concern at Superfund Sites, May 2024, or the most up to date RSLs, will be used under for residential land-use scenario to screen the data collected for potential risk to human health. If the analytical results for the soil confirmation samples report concentrations less than the published RSLs for the residential land-use scenario, then NGSC may elect to approach the Division for a No Further Action determination. If the analytical data indicates that corrective action is required to meet the selected closure criteria, NGSC will submit a corrective measures plan after concurring with the Division.
