The SMP was submitted to the Utah Division of Waste Management and Remediation Control (UDWMRC) in April 2018 (ATK, 2018) and approved in May 2018. The SMP was developed to comply with the Permit. The SMP was developed to provide surface soil data in support of the OBOD Human Health Risk Assessment (HHRA) (Geosyntec, 2016), which utilized air dispersion and deposition and the Lakes Environmental risk assessment model (Lakes, 2014) to evaluate risks from constituents of potential concern (COPC) to human health. The Lakes and air quality models identified the point of maximum deposition and risk, based on exposure to off-site residents and farmers. The Lakes model also estimated maximum soil COPC concentrations based on modeled deposition and soil mixing over time. The purpose of the SMP was to collect soil samples from the point of predicted maximum risk, as well as from seven background soil locations. The soil data collected under the SMP are compared to the modeled soil concentrations at the point of predicted maximum risk, for the list of constituents determined to be risk drivers by the Lakes model (Section 2), and to background soil concentrations for the same modeled constituents. In addition, the soil data are compared to risk-based values obtained from the USEPA Regional Screening Levels (RSLs) (EPA, 2018) to determine whether further evaluation of soils is warranted. 2.0 SOIL MONITORING LOCATIONS AND ANALYTES The soil sample locations for both background (Figure 1) and the point of predicted maximum risk (Figure 2) were identified in the SMP. Page 11 IVOR779110P GRUMMAN Soil Monitoring Results Hazardous Waste Storage and Subpart X Treatment Permit Table 1 presents the list of risk drivers from the 2016 HHRA, in order of highest to lowest risk. Hexavalent chromium (Cr(VI)) is the number one risk driver, accounting for 50% of the total risk to an adult farmer at the location of predicted maximum risk. (Note that this is a hypothetical scenario, and there is no farm or residence located at this point.) The remainder of the risk drivers that were also detected in the emissions tests include nine individual congeners of dioxin/furans (D/F), the two polynuclear aromatic hydrocarbons (PAHs) benzo(a)anthracene and benzo(k)fluoranthene, and nickel. These risk drivers are shown in bold in Table 1, and these COPCs were retained as analytes under the SMP. In addition, total chromium was selected as an analyte, for use in interpretation of the Cr(VI) results. 2.1 BACKGROUND SAMPLE LOCATIONS AND ANALYTES A total of seven background surface soil samples were collected on October 29, 2018. The sample locations are consistent with those from the November 2016 sampling event and represent a wide geographical range outside of ATK's property boundary and the OBOD burning grounds (Figure 1). A single sample was collected at each location and it is assumed that the COPC concentrations do not vary significantly at each background location. The analyte list for the 2016 sampling did not include D/F, but did include total chromium, Cr(VI), nickel, benzo(a)anthracene and benzo(k)fluoranthene, and the results are compared to the latest samples. 2.2 PREDICTED OFF-SITE MAXIMUM RISK SAMPLE LOCATIONS A total of eleven surface soil samples were collected on October 30, 2018 at the point of predicted maximum risk identified by the Lakes Model: nine primary samples plus two field duplicates (M- 01A and M-09A), from the square grid pattern rneasuring approximately 200 meters on each side, covering 40,000 square meters (m2) (Figure 2). Page l 2 1VORMRCPP caRtneoirAN Soil Monitoring Results Hazardous Waste Storage and Subpart X Treatment Permit 3.0 SAMPLE COLLECTION METHODS ATK collected the soil samples in accordance with the approved SMP. Sample jars were provided by ALS Environmental (ALS), along with the appropriate preservatives, if required under the analytical method. The samples were collected using a pre-cleaned stainless-steel spoon. Soil was sampled down to a depth of approximately three inches and placed into a pre-cleaned plastic bowl. Plant material, roots, and rocks were manually removed to the extent practicable. The soil was lightly mixed before being placed into the sample jars. The analytes of interest were metals, PAHs/semi- volatile organic compounds, and dioxins/furans; analyte loss is likely insignificant using this collection technique. The jars were labeled, and sample identifications were documented on the chain-of-custody. The samples were stored and shipped in an iced cooler. Any field notes recorded by the sampler are on file with ATK, and available upon request. 4.0 ANALYTICAL DATA PACKAGES All soil samples were analyzed by ALS Environmental Laboratories. The metals and PAH analyses were performed at the ALS laboratory in Salt Lake City, Utah; the full data package is provided in Appendix A. Table 2 presents a summary of the metals and PAH results for the individual samples. Total chromium and nickel were analyzed by Method SW 6020 and Cr(VI) was analyzed by Method 7196. The PAHs were limited to the detected risk drivers benzo(a)anthracene and benzo(k)fluoranthene, and the analyses were performed under Method SW 8270 Selective Ion Monitoring (SIM). The D/F analyses were performed using Method 8290 at the ALS laboratory in Houston, Texas and the full D/F data package is provided in Appendix B. Table 3 presents a summary of the D/F results for the nine individual congeners identified as detected risk drivers in the OBOD HHRA. Page 13 IVORTIVROP GRUPOPIAAl Soil Monitoring Results Hazardous Waste Storage and Subpart X Treatment Permit 4.1 DIOXIN/FURAN - CASE NARRATIVE/QUALITY CONTROL SAMPLES The case narrative provided for the dioxin/furan results indicated that the samples were received in good condition and at the proper temperature at the Houston laboratory. The case narrative also presents a discussion of the associated quality control (QC) samples that were analyzed under Method 8290. Quality control samples analyzed under Method 8290 included a method blank, laboratory control sample (LCS) and LCS duplicate (LCSD). The results of the method blank were non-detect, with the exception of low-level detections for 1,2,3,4,6,7,8-Heptachlorodibenzo-p-dioxin (HpCDD) and octochlorodibenzo-p-dioxin (OCDD) (not a risk driver). Samples with results less than ten times the amount of 1,2,3,4,6,7,8-HpCDD found in the blank were flagged with a "B" by the laboratory. All OCDD results were more than ten times the amount found in the blank, therefore no OCDD results were flagged. Results for the LCS and LCSD indicate the recoveries were within established control limits, except for OCDD, 2,3,7,8-Tetrachlorodibenzofuran (TCDF) and 2,3,4,6,7,8-HpCDF, which were slightly low; these QC samples were flagged with a "Y" by the laboratory. ALS indicated in the case narrative that in all cases, the signal-to-noise ratios were greater than 10:1, making the recoveries acceptable. 4.1.1 Dioxin/Furan TEO Appendix B contains the D/F laboratory data package. The laboratory reported results for all of the D/F congeners, not just the risk drivers that were also detected in the emissions tests, shown in Tables 2 and 4. The laboratory also reported a toxicity equivalence quotient (TEQ) for each sample. The TEQ utilizes a toxicity equivalence factor (TEF) based on the relative toxicity of each congener to 2,3,7,8-TCDD, in accordance with EPA risk assessment guidance (EPA, 2003). The TEQs presented in Appendix B provide a measure of toxicity that is based on a sum of 17 individual congeners, not just the nine detected risk drivers identified in the HHRA. The TEQs presented in Appendix B are for informational purposes only. The SMP was written with the intent of screening the nine congeners individually against the risk-based RSLs presented in Tables 2 and 4. In addition, Table Page 14 MOR7WROP CRUMMAIV Soil Monitoring Results --------- 5 presents a summary of the TEQs for the nine congeners of interest and a partial TEQ based on summing the nine TEQs. TEQs were not calculated by the laboratory for congeners with non- detected results. 4.2 METALS/PAH - CASE NARRATIVE/QUALITY CONTROL SAMPLES The case narratives for the metals/PAHs indicates that the samples were received in good condition and at the proper temperature at the Salt Lake City laboratory. 4.2.1 Method SW 6020 The case narrative for Method SW 6020 indicates that all samples were extracted and analyzed within holding times. No target compounds were detected above the reporting limit in the laboratory method blank. Method criteria were met for both initial and continuing calibration verification standards, serial dilution and post digestion spike analysis. One matrix spike and duplicate were prepared with this sample batch. 4.2.2 Method SW 7196 The case narrative for Method SW 7196 states: -1Iexavalent Chromium concentration was determined by the colorometric analysis for the product formed by a reaction with dephenylcarbazide in an acid solution. It was noted that the prepared soil samples produced colored liquid solutions. The color was not removed from these solutions by either centrifugation or filtration. Absorbance at the same wavelength as the product of interest could bias results high." The Cr(VI) concentrations are elevated for all samples (background and off-site) and are equal to or greater than the total chromium concentrations for most of the samples. Table 4 provides a comparison of the 2016 and 2018 metals concentrations for the background samples. The 2016 and 2018 total chromium and nickel concentrations are similar, while the 2018 Cr(VI) results are approximately 10 - 150 times higher than the 2016 results. Hazardous Waste Storage and Subpart X Treatment Permit Page 15 AfORMROP elltiFINAIV Soil Monitoring Results Hazardous Waste Storage and Subpart X Treatment Permit Based on discussions with the laboratory regarding the analytical interference and the method utilized, ATK plans to resample and reanalyze for Cr(VI) using their on-site laboratory using the method described below. The 2018 Cr(VI) results are considered invalid, and were not carried forward in the summary statistics and data evaluation. 4.2.2.1 Method SW 7196 vs 7199 There are two analytical methods being compared with respect to the Cr(VI) testing: Method 7196 (Hexavalent Chromium by Colorimetry) performed by ALS laboratory; and, Method 7199 (Hexavalent Chromium by Ion Chromatography) performed by NGIS laboratory. Both methods begin with an alkaline digestion, Method 3060, to extract the Cr(VI) from the soil matrix. The Colorimetric procedure, Method 7196, takes a portion of the extracted solution and adds measured reagents that form a colored complex which is then quantified colorimetrically using a UV/Vis spectrometer. This technique has a detection limit on the order of about 0.5 ppm. There are known interference issues with this technique that may have caused the reported results to be biased high. Specifically, any colored species present that absorbs light at the same wavelength as the Cr(VI) colored complex will cause a higher than expected reading. The Ion Chromatography procedure, Method 7199, works on the same principle of taking a portion of the sample then reacting with measured reagents to form a colored complex that is quantified with a UV/Vis Spectrometer. This technique is a bit more sensitive and has a detection under 0.1 ppm. While there are similarities between the techniques there is one main difference and that is the Ion Chromatograph column. The sample is flowed through the chromatographic column which causes the varied analytes in the sample to be spread out over time as the different species flow through the column at different rates. The outcome is that the Cr(VI) , is isolated away from many of the interfering species know to be problematic in the colorimetric method. Page l 6 Soil Monitoring Results Hazardous Waste Storage and Subpart X Treatment Permit 4.2.3 Method SW 8270 The case narrative for Method SW 8270 indicates that all samples were extracted and analyzed within holding times. No target compounds were detected above the reporting limit in the laboratory method blank. Method criteria were met for all surrogates and internal standards, and both initial and continuing calibration verification standards. One sample (BG#5) required a 5X dilution to bring the results for benzo(a)anthracene within range of the instrument calibration. One matrix spike and duplicate were prepared with this sample batch. 4.3 FIELD DUPLICATE SAMPLES Field duplicates M-0 1 A and M-09A were collected from locations M-01 and M-09, respectively, in lieu of the blind duplicates identified in the SMP. Field duplicates are collocated samples utilized to assess the overall precision of the field sampling procedures and analytical method. The relative percent difference (RPD) can be calculated to provide a measure of the variability between primary and duplicate sample pairs when both samples are detected at concentrations greater than the reporting limit. Data validation guidance does not specify an acceptable limit for the RPD of field duplicates. The results of the two field duplicate sample pairs generally show good agreement for all of the D/F risk drivers, which are either non-detects or were reported as low-level detections with concentrations considered to be estimates, (J flag) between the estimated detection limit (EDL) and the method reporting limit (MRL). The RPD is not calculated in these instances. The metals results also show good agreement, with calculated RPDs at 5% or less. RPDs are not calculated for the PAHs, because the results are a combination of non-detects and low-level detections (J flags) for either the primary or duplicate sample. 5.0 RESULTS AND SUMMARY STATISTICS The results of the individual samples for both the background locations and the predicted maximum off-site risk locations are presented in Tables 1 and 2, for the PAH and metals data, and the D/F data, Page 17 AFORMRCPP GRUOINIZAA, Soil Monitoring Results Hazardous Waste Storage and Subpart X Treatment Permit respectively. In addition, the modeled concentrations presented in the HHRA are presented in Tables 1 and 2. Table 7 provides summary statistics including the minimum and maximum detected concentrations, the number of detected results and the calculated 95 percent upper confidence level (95UCL), if applicable. For those analytes with at least four detected results, 95UCLs were calculated. Table 7 also presents the RSL for each of the risk drivers. The detected concentrations reported in Tables 1 and 2 for the individual samples collected from both the background locations and the point of maximum off-site risk are greater than the modeled concentrations from the HHRA, but well below the risk-based RSLs. Note that the modeled concentrations are well below the detection limits for all analytes. Therefore, any detected result would be above the modeled result. 5.1 BACKGROUND A review of the 2018 data for the background locations identified two samples (BG#5 and BG#6) with elevated concentrations for PAHs and D/Fs, compared to the other five background samples. Benzo(a)anthracene and benzo(k)fluoranthene concentrations for samples other than BG#5 are less than the RSLs; BG#5 concentrations are 1300 and 460 pg/kg, respectively (Table 2). While the source of the PAHs at this location is not known, there are many anthropogenic sources of PAHs that could have contributed to the elevated oncentrations reported in BG#5, as described below. 5.1.1 Anthropogenic Sources of PAHs Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the environment and, in many cases, the result of combustion or burning processes, including: • Wood burning, including home heating, camp fires, agricultural burning and forest fires, • Volcanic eruptions, • Municipal and industrial waste incineration, • Coal combustion (e.g., historical manufactured gas plants, steam engines), • Car, truck, and train exhaust, and Page 18 Soil Monitoring Results Hazardous Waste Storage and Subpart X Treatment Permit • Cigarette smoke Once airborne, PAHs may be transported great distances before deposition occurs (ATSDR, 1995). In addition, PAHs are present in many of the following consumer and commercial products: • Coal and coal tar, • Fumigants (e.g., moth balls), • Asphalt and asphalt sealants, • Creosote-treated wood products, and • Wetting agents (ATSDR, 1995; Mahler et al, 2005; Mauro et al., 2006) Finally, PAHs are present in various industrial processes, such as waste water treatrnent plants, petroleum refining facilities and wood preserving facilities (e.g., creosote-treated wood products) (ATSDR, 1995). At one time waste oil was used to suppress road-side vegetation, which also contributed to the general background level of PAHs in the environment. Historically the area to the west of ATK has multiple PAH sources, including railroad transport by coal-burning steam engines, which historically generated a large amount of smoke, which settled across the railroad right of way and vicinity. Modem rail transport uses diesel locomotives, which generates PAHs in the exhaust. Wooden rail ties are treated with creosote and likely contribute to soil impacts near the right of way. In addition, historical agricultural burning and residential waste incineration (barrel burning) has been noted in the area. Therefore, PAHs are ubiquitous in the environment and in both urban and rural areas there is likely no location that has not been impacted in some way by PAHs. 5.1.2 Anthropogenic Sources of Dixon/Furans Similarly, for BG#6, the D/F results for four of the congeners were elevated compared to the other background samples (shown shaded in Table 3). Subsequent to receiving the analytical data, ATK revisited the location and learned that BG#6 was collected from an area that was formerly an unpermitted landfill, which caught on fire at some point (ATK, 2019). When ATK collected the sample, there was no indication of a former landfill and the vegetation and soil appeared to be typical Page 19 Al01177~ OFICAMMAN Soil Monitoring Results Hazardous Waste Storage and Subpart X Treatment Permit for that area. Burning trash at landfills is known to be a source of D/Fs (EPA, 2003). Similar to PAHs, chlorinated dibenzo-p-dioxins (CDDs) and chlorinated dibenzofurans (CDFs) are ubiquitous in the environment and the result of combustion, burning or incineration and a number of chemical manufacturing processes, including: • Wood burning, including agricultural burning and forest fires, • Volcanic eruptions, • Municipal, medical, and industrial waste incineration, • Coal, oil, and natural gas combustion (e.g., modern power plants, historical manufactured gas plants, steam engines, home-heating systems), • Chlorine bleaching process used in pulp or paper industry • Burning chlorine-containing materials (e.g., plastics, treated wood, pesticide-treated waste, bleached paper), • Chlorinated pesticides/herbicides • Burning electrical equipment containing polychlorinated biphenyls (PCBs) (e.g., equipment malfunction), • Car, truck, and train exhaust, • Cigarette smoke (ATSDR, 1994 and 1998; USEPA, 2006), and • Associated with pentachlorophenol (PCP) manufacturing and PCP treated products (such as railroad ties, agricultural and residential fencing and telegraph poles) (ATSDR, 1994 and 1998; USEPA, 2006). Once airborne, CDDs and CDFs present in smoke, ash or particulates will travel some distance via air dispersion before deposition occurs; whereas CDDs/CDFs present as vapors will travel great distances before deposition occurs. Note, 20-60 percent (%) of airborne 2,3,7,8-TCDD is typically present in the vapor phase (ATSDR, 1994 and 1998). As discussed in Section 5.1.1, the historical railroad and agricultural activities that occurred in the vicinity of ATK have likely contributed to the presence of CDD/CDF in the soil. Specifically, railroad transport by coal-combustion steam engines, which historically generated a large amount of smoke, which settled across the railroad right of way and vicinity. Modern rail transport uses diesel locomotives, which may also generate CDDs and CDFs in the exhaust. In addition, historical Page I 10 NORMROP GRUPIIMAN Soil Monitoring Results Hazardous Waste Storage and Subpart X Treatment Permit agricultural burning of crops/weeds likely treated with chlorinated pesticides or herbicides has been noted in the area, as well as residential backyard barrel burning. The elevated D/F concentrations reported in sample BG#6 are likely related to a historical fire(s) which burned at the former private landfill that is located there. Therefore, while samples BG#5 and BG#6 do not represent clean, unimpacted areas. However, they do serve as Reference Samples for the area, and they demonstrate anthropogenic impacts independent of ATK. Samples BG#5 and BG#6 are reported in Tables 1 and 2, and summary statistics are presented for all seven background/reference samples in Table 6. These data are included for comparison to the five selected background samples (BG#1 — BG#4 and BG#7) summarized in Table 7. The following sections present a discussion of the selected set of five background samples. 5.1.3 PAH Results The background results for benzo(a)anthracene ranged from 0.63 — 1.8 pg/kg. The calculated 95UCL is 1.56 pg/kg. The results for benzo(k)fluoranthene were mostly non-detect, with one detection at 0.79 pg/kg. 95UCLs were not calculated for benzo(k)fluoranthene because there were too few detections. 5.1.4 Total Chromium and Nickel Results The background results for total chromium ranged from 12 to 17 milligrams per kilogram (mg/kg) and the 95UCL is 16.46 mg/kg. The background results for nickel ranged from 11 to 21 mg/kg and the 95UCL is 20.07 mg/kg (Table 7). Table 4 presents the total chromium and nickel results for both the 2016 and 2018 background locations BG#1 through BG#7 and the calculated 95UCLs. The 2018 results are very comparable, and on the same order of magnitude as the 2016 results. Note that samples BG#5 and BG#6 were removed from the 2018 background dataset, as discussed in Section 5.1. Therefore, the 95UCLs for both 2016 and 2018 were based on five samples. Page I 11 IVORTAIROP GRIA41144Pi Soil Monitoring Results Hazardous Waste Storage and Subpart X Treatment Permit 5.1.5 Dioxin/Furan Results The range of detected results for the D/F risk drivers in the five valid background samples are provided in Table 6. There were too few detected results to calculate 95UCLs. 5.1.6 Hexavalent Chromium Results As discussed in Section 4.2, the laboratory indicated there was a problem with the Cr(VI) analysis and a positive interference led to results that are biased high. The Cr(VI) results are two to three orders of magnitude higher than those reported in 2016 (Table 4). ATK intends to resample background locations BG#1-4 and BG#7 and reanalyze for Cr(VI). 5.2 PREDICTED MAXIMUM OFF-SITE RISK Results are presented for 11 samples (M-01 to M-09 and two field duplicates) collected from the point of predicted maximum off-site risk, in Tables 1 and 2. The summary statistics including the minimum and maximum detected concentrations, the number of detected results and the calculated 95UCL, if applicable are presented in Table 7. In the subsections below the results are compared to both the background samples and the RSLs. 5.2.1 PAH Results The results for benzo(a)anthracene range from 0.63 — 4.5 ptg/kg. The calculated 95UCL is 4.04 lig/kg. The results for benzo(k)fluoranthene range from 0.83 — 2.7 pig/kg. The calculated 95UCL is 1.75 lig/kg. The range of detected results overlap with the background dataset, although the maximum detected concentrations and the 95UCLs are slightly higher for the point of predicted maximum off-site risk. Both the maximum detected concentrations and the 95UCLs are well below the RSLs for the PAHs. Page 112 a Atnce cart.mogram Soil Monitoring Results Hazardous Waste Storage and Subpart X Treatment Permit 5.2.2 Metals Results The results for total chromium range from 12 to 19 mg/kg and the calculated 95UCL is 16.9 mg/kg. The results for nickel range from 9.7 to 14 mg/kg and the calculated 95UCL is 13.5 mg/kg. Total chromium and nickel results for the predicted maximum off-site risk locations overlap with the background concentrations, and the 95UCLs are similar, although the 95UCL for nickel in background is higher than the 95UCL for the predicted maximum off-site risk location. As noted in Section 4.2, Cr(VI) results were determined to be invalid due to an interference with the analytical method. ATK plans to resample and reanalyze for Cr(VI). 5.2.3 Dioxin/Furan Results The range of detected results for the D/F risk drivers in the predicted maximum risk samples are provided in Table 7. Three of the nine D/F congeners were non-detect, and three more had too few detections to calculate 95UCLs. Three congeners had sufficient detections to calculate 95UCLs: 1,2,3,4,7,8-Hexachlorodibenzofuran, 1,2,3,6,7,8-Hexachlorodibenzofuran, and 2,3,4,6,7,8- Hexachlorodibenzofuran. The range of detected results was comparable to the background dataset, - although the maximum detected concentration for the point of predicted maximum risk was slightly higher than the background dataset for four of the congeners. The remaining congeners were slightly higher in the background samples (after the elevated background samples were removed from the dataset). Both the maximum detected concentrations and the 95UCLs are well below the RSLs for the individual congeners. 6.0 CONCLUSIONS Soil samples were collected in October 2018 in support of the OBOD HHRA. The maximum detected concentrations and 95UCLs were compared to both the modeled concentrations presented in the HHRA and risk-based screening levels. Two of the background samples (BG#5 and BG#6) Page l 13 1VORM GREMOIAIV Soil Monitoring Results Hazardous Waste Storage and Subpart X Treatment Permit were identified as Reference Samples, due to elevated concentrations of PAHs and D/Fs, likely due to anthropogenic sources independent of ATK. The PAH concentrations in BG#5 exceed the RSLs, but all other reported concentrations are well below their respective RSLs. The five remaining background samples were summarized and compared with those from the point of predicted maximum risk; both of which had comparable results and both were greater than the modeled concentrations. After removing BG#5 from the background dataset, constituent concentrations in soil in the remaining datasets were well below the RSLs in all cases. Due to a laboratory analytical issue, the results for Cr(V1) were found to be invalid and while presented here for transparency, they were not utilized in decision making. ATK proposes to resample background and the predicted maximum locations and reanalyze Cr(VI) in 2019 and submit an addendum to this report. Based on the low concentrations detected in surface soil, the low level of predicted constituent deposition and low level of facility use compared with the permit limits, ATK proposes to resample soil in five years and reevaluate at that time.

Daphne Robinson 29 January 2019 AALS Case Narrative Method: 8270D Client: Northrop Grumman - Analysis: 8270 SIM, PAH Orbital ATK Propulsion SOP ref: OE-SW-3550, OS-SW-8270D Systems Set ID: 1830599 Matrix: Soil General Set Information: There are eighteen field samples in this reporting group. Method Summary: This is a GC/MS method for determination of polynuclear aromatic hydrocarbon (PAH) compounds in extracts prepared from soil according to the SW-846 Guidelines. A thirty gram portion of the sample is spiked with surrogates, extracted by sonication, and concentrated to a final volume of one milliliter. The resulting extract is analyzed using an Agilent model 5975 GC/MS system with an electron impact ionization source and a quadrapole mass-filter detector in the selected ion monitoring (SIM) mode. Sample Preparation: All samples were prepared in accordance with methods 3550 and 8270D. Dilutions: Sample 1830599001 required a 5x dilution to bring the result for benzo(a)anthracene within range of the instrument calibration. Holding Times: All samples were extracted and analyzed within holding times. Method and Sample QC data: The method blank met method criteria with no target compounds detected above the reporting limit. All samples met internal standard area criteria. Surrogates pass method criteria in every sample. All compounds were within QC limits in the LCS. MS/MSD Analysis: An MS/MSD was prepared using sample 1830599001. Instrument QC: An eight-point initial calibration curve was analyzed prior to sample analysis. The concentrations of the standards were: 0.01, 0.05 (RL), 0.2, 0.5, 2, 5, 10 and 20 µg/mL. A calibration verification standard at a concentration of 2 lig/mL was analyzed to verify instrument response against the initial calibration. The initial calibration passed method criteria for all compounds. The Continuing Calibration Verification passed method criteria for all compounds. Sample Calculations: Relative Response Factor: RRF = [Ax / Ais] [Cis / Cx] Where Ax is the area of the characteristic ion for the compound to be measured, Ais is the area of the characteristic ion for the internal standard, Cis is the concentration of the internal standard, and Cx is the concentration of the compound to be measured.

Service Request No.: E1801011 Project: 1830602 Date Received: 11/06/18 Sample Matrix: Soil CASE NARRATIVE All analyses were performed in adherence to the quality assurance program of ALS Environmental. This report contains analytical results for samples designated for Tier II. When appropriate to the method, method blank results have been reported with each analytical test. Sample Receipt Eighteen samples were received for analysis at ALS Environmental in Houston on 11/06/18. The samples were received at 4.7 °C in good condition and are consistent with the accompanying chain of custody form. The samples were stored in a refrigerator at 4°C upon receipt at the laboratory. Data Validation Notes and Discussion B fins — Method Blanks The Method Blank EQ1800473-01 contained low levels of various dioxins furans compounds below the Method Reporting Limit (MRL). The associated compounds in the samples are flagged with 'IV flags where the sample result is less than ten times the level detected in the method blank. MS/MSD EQ1800473: Laboratory Control Spike/Duplicate Laboratory Control Spike (LCS/DLCS) samples were analyzed and reported in lieu of an MS/MSD for this extraction batch. Y Baas — Labeled Standards Quantification of the native 2,3,7,8-substituted congeners is based on isotopic dilution, which automatically corrects for variation in extraction efficiency and provides accurate values even with poor recovery. Samples that had recoveries of labeled standards outside the acceptance limits are qualified with 'Y' flags on the Labeled Compound summary pages. In all cases, the signal-to-noise ratios are greater than 10:1 and detection limits were below the Method Reporting Limits. K flags EMPC - When the ion abundance ratios associated with a particular compound are outside the QC limits, samples are flagged with a 'K' flag. A 'K' flag indicates an estimated maximum possible concentration for the associated compound. Detection Limits Detection limits are calculated for each analyte in each sample by measuring the height of the noise level for each quantitation ion for the associated labeled standard. The concentration equivalent to 2.5 times the height of the noise is then calculated using the appropriate response factor and the weight of the sample. The calculated concentration equals the detection limit. E1801011 3 of 126 2378-TCDF Samples analyzed on the DB-5MSUI column were analyzed under conditions where sufficient separation between 2,3,7,8-TCDF and its closest eluter was achieved. Confirmation of this result was not required. The TEO Summary results for each sample have been calculated by ALS/Houston to include: WHO-2005 TEFs, The 2005 World Health Organization Reevaluation of Human and Mammalian Toxic Equivalency Factors for Dioxins and Dioxin-Like Compounds (M. Van den Berg et al., Toxicological Sciences 93(2):223-241, 2006) Non-detected compounds are not included in the 'Total' The results of analyses are given in the attached laboratory report.

Cooler Custody Seals (desirable, mandatory if specified in SAP): • Intact on outside of cooler, signed and dated Chain-of-Custody (COC) documentation (mandatory): The following is required on each COC. • Sample ID, the location, date and time of collection, collector's name, preservation type, sample type, and any other special remarks concerning the sampleThe COC must be completed in ink. • Signature and date of relinquishing party. In the absence of a COC at sample receipt, the COC will be requested from the client. Sample Integrity (mandatory): Samples are inspected upon arrival to ensure that sample integrity was not compromised during transfer to the laboratory. ✓ Sample containers must arrive in good condition (not broken or leaking). ✓ Samples must be labeled appropriately, including Sample IDs, and requested test using durable labels and indelible ink. ✓ The correct type of sample bottle must be used for the method requested. ✓ An appropriate sample volume, or weight, must be received. ,4 Sample IDs and number of containers must reconcile with the COC. ✓ Samples must be received within the method defined holding time. Temperature Requirement (varies by sample matrix): • Aqueous and Non-aqueous samples must be shipped and stored cold, at 0 to 6°C. ✓ Tissue samples must be shipped and stored frozen, at -20 to -10°C. ✓ Air samples are shipped and stored cold, at 0 to 6°C ✓ The sample temperature must be recorded on the COC All cooler inspections are documented on the Cooler Receipt Form (CRF). A separate CRF is completed for each service request. Any samples not meeting the above criteria are noted on the CRF and the Project Manager notified. The Project Manager must resolve any sample integrity issues with the client prior to proceeding with the analysis. Such resolutions are documented in writing and filed with the project folder. Data associated with samples received outside of this acceptance policy will be qualified on the case narrative of the final report E1801011 20 of 126 Enutroromental Preparation Information Benchsheets ALS Environmental - Houston HRMS 10450 Stancliff Rd., Suite 210, Houston, TX 77099 Phone (713)266-1599 Fax (713)266-0130 www.alsglobal.com E1801011 21 of 126 ilklEILILIPAPAntillAf4AsIPett Prep Run#: 326543 Team: Semivoa GCMS/ALOPEZ Lab Code Client ID E1801011-001 BG#5 2 E1801011-002 BG#7 3 E1801011-003 BG#6 4 E1801011-004 BG#4 5 E1801011-005 BG#1 6 E1801011-006 BG#2 7 E1801011-007 BG#3 8 E1801011-008 M-01 9 E1801011-009 M-01A 10 E1801011-010 M-02 11 E1801011-011 M-03 12 E1801011-012 M-06 13 E1801011-013 M-09 14 E1801011-014 M-09A 15 E1801011-015 M-08 16 E1801011-016 M-05 17 E1801011-017 M-04 18 E1801011-018 M-07 19 E1801015-001 2348123001 2ð E1801015-002 2348123002 21 EQ1800473-01 MB 22 EQ1800473-02 LCS 23 EQ1800473-03 DLCS Spiking Solutions I Name: 1613B Matrix Working Standard EQ1800473-02 100.001.iL EQ1800473-03 I Name: 1613B Labeled Working Standard E1801011-001 1,000.001.tL E1801011-002 E1801011-007 1,000 00AL E1801011-008 E1801011-013 1,000.004, E1801011-014 E1801015-001 1,000.001.tL E1801015-002 13# Prep WorkFlow: Prep Method: Method /Test pH CI OrgExtDioxS(30) Method Matrix Amt.
