Dear Ms. Kilburn:

On behalf of the Waste Management of Arkansas Inc. (WM) Eco-Vista Class 1 Landfill (the landfill),

FTN Associates, Ltd. (FTN) is submitting this response to the letter sent to Ms. Jodi Reynolds-Coffelt

of WM from the Arkansas Department of Environmental Quality (ADEQ) dated January 7, 2019

(ADEQ Document Identification Number [DIN] 75256).

The ADEQ comments and WM’s responses to each are presented below:

ADEQ Comment 1: In Appendix E Statistical Evaluation, July 2018 Event under Summary of

Statistical Limit Exceedances during the Third Quarter Monitoring Period in 2018 states that “The

resample sulfate concentration at MW-15 (11.0 mg/L) confirms the initial exceedance at LGW-15.”

MW-15 cannot confirm an exceedance at another well. LGW-15 was not even resampled. Please

explain this inconsistency.

WM Response: The inconsistency noted above was a typographical error. The report should

have stated “The resample sulfate concentration at MW-15 (11.0 mg/L) confirms the initial

exceedance at MW-15.” A revised Appendix E correcting the error is included as

Attachment 1 to this letter.

ADEQ Comment 2: Also, in Appendix E, Attachments A through E are not included in the report.

Please resubmit Appendix E with all attachments.

WM Response: A revised Appendix E that includes Attachments A through E is included as

Attachment 1 to this letter.

ADEQ Comment 3: Document ID 74554 states that FTN Associates, Ltd. would submit a NEI work

plan by October 19, 2018. ADEQ has not received this work plan. Please submit a NEI work plan.

WM Response: As FTN discussed with Robert Cramer with ADEQ via telephone on January

18, 2019, the NEI work plan is in progress and WM expects to submit the NEI work plan to

ADEQ in February 2019. WM anticipates submittal of the work plan no later than February

28, 2019.

ADEQ Comment 4: In Section 6.0 Corrective Action Monitoring the report states that “wells NE-6

through NE-13 are not currently required to be sampled as part of the monitoring program.” In

Document ID 74217 ADEQ requested the wells NE-6 through NE-13 to be sampled during semi-

annual groundwater sampling events. It was acknowledged in Document ID 74554 that the facility

would sample the wells as requested. Please amend the text and provide an explanation and correction

for the oversight.

WM Response: Wells NE-6 through NE-13 will be sampled on a semiannual basis beginning

in the first half of 2019. The second half of 2018 sampling event, performed during July 2018,

had already been completed (July 10 to July 18, 2018) when WM committed to semiannual

sampling in Document ID 74554 (September 13, 2018). As requested, page 6 of the report was

revised to reflect this upcoming change and is attached to this letter.

If you have any questions regarding this submittal, please contact me at (314) 786-5855 or

Introduction This report contains the results of the statistical analyses used to evaluate the ground water data obtained during the third quarter monitoring event in 2018 at Eco Vista Sanitary Landfill. The ground water monitoring well network at Eco Vista Sanitary Landfill includes MW-1N, MW-2N, MW-3N, MW-7N, MW-8N, MW-10N, MW-11N, MW-15, MW-16, MW-17, MW-19, MW-20, MW-21, LGW-2, LGW-3R, LGW-4, LGW-5, LGW-6, LGW-7, LGW-8R, LGW-9, LGW-10, and LGW-14R. These monitoring wells were sampled during July 10-17, 2018 and analyzed for the parameters required by permit. The statistical plan is designed to detect a release from the facility at the earliest indication so that it is protective of human health and the environment. An intrawell methodology is described and then applied to the Eco Vista Sanitary Landfill data. The statistical plan conforms with USEPA Guidance document (“Statistical Analysis of Ground-Water Monitoring Data at RCRA Facilities, Unified Guidance”, March 2009), and the American Society for Testing and Materials (ASTM) standard D6312-98, Developing Appropriate Statistical Approaches for Ground-Water Detection Monitoring Programs. Ground Water Monitoring Program The groundwater monitoring network for Eco Vista Sanitary Landfill includes the twenty-three wells designated above. Each of the groundwater monitoring wells is to be sampled and analyzed for the detection monitoring parameters listed below. Acetone trans-1,4-Dichloro-2-butene Iodomethane Acrylonitrile 1,1-Dichloroethane 4-Methyl-2-pentanone Benzene 1,2-Dichloroethane Styrene Bromochloromethane 1,1-Dichloroethene 1,1,1,2-Tetrachloroethane Bromodichloromethane cis-1,2-Dichloroethene 1,1,2,2-Tetrachloroethane Bromoform trans-1,2-Dichloroethene Tetrachloroethene Carbon disulfide 1,2-Dichloropropane Toluene Carbon tetrachloride cis-1,3-Dichloropropene 1,1,1-Trichloroethane Chlorobenzene trans-1,3-Dichloropropene 1,1,2-Trichloroethane Chloroethane Ethylbenzene Trichloroethene Chloroform 2-Hexanone Trichlorofluoromethane Dibromochloromethane Bromomethane 1,2,3-Trichloropropane 1,2-Dibromo-3-chloropropane Chloromethane Vinyl acetate 1,2-Dibromoethane Dibromomethane Vinyl chloride 1,2-Dichlorobenzene Methylene chloride Xylenes (Total) 1,4-Dichlorobenzene 2-Butanone Antimony, Total Chromium, Total Selenium, Total Arsenic, Total Cobalt, Total Silver, Total Barium, Total Copper, Total Thallium, Total Beryllium, Total Lead, Total Vanadium, Total Cadmium, Total Nickel, Total Zinc, Total Chloride Sulfate pH Iron Total Dissolved Solids (TDS) Specific Conductance Manganese Total Organic Carbon (TOC)

The ground water data obtained during the third quarter monitoring event in 2018 are summarized in Attachment A. STATISTICAL METHODOLOGIES FOR DETECTION MONITORING The statistical guidance provides several options for statistically evaluating the ground water data at those wells that monitor the open cells or contiguous MSWLF units. The preferred methods for comparing inorganic ground water data are using either prediction limits or using control charts. Both of these methods were initially applied to the Eco Vista Sanitary Landfill data using the DUMPStat® statistical program. DUMPStat® is a program for the statistical analysis of groundwater monitoring data using methods described in “Statistical Methods for Groundwater Monitoring” by Dr. Robert D. Gibbons. The DUMPStat program is completely consistent with all USEPA regulations and guidance and the ASTM D6312-98 guidance. It was previously determined that an intrawell control chart method is the more appropriate statistic for Eco Vista Sanitary Landfill. Ground water statistics are to be done on the inorganic constituents listed. The organic constituents are compared to practical quantitation limits (PQLs), in lieu of statistical comparisons to historical concentrations. Volatile Organic Compounds Volatile Organic Compounds (VOCs) are generally man-made compounds not present in ambient ground water. If VOCs are initially detected above their statistical limit (i.e., the laboratory PQL or reporting limit), a verification resample will be conducted at the next scheduled sampling event. A statistical exceedance will be indicated if the VOC detection is confirmed by the subsequent monitoring. VOCs detected in the ground water at Eco Vista Sanitary Landfill during the third quarter monitoring event in 2018 are summarized in the table below. Acetone was detected at wells LGW-14R, LGW-2, LGW-3R, LGW-8R, MW-10N, MW-11N, and MW-1N, however acetone was also detected in the associated equipment blank and trip blank at similar concentrations. The current acetone detections are likely artifacts of the sampling or analyses. Historical detections are summarized in Attachment B.

Intrawell statistics Intrawell statistics are appropriate for facilities where the upgradient wells do not accurately characterize the natural ground water conditions downgradient from the facility. This may be due to different hydrogeological conditions where the wells are screened, having too few upgradient wells to account for the spatial variability, or the site exhibiting no definable hydraulic gradient. Intrawell statistics compare new measurements to the historical data at each ground water monitoring well independently. It is recommended that at least eight background samples be obtained prior to performing the statistics. The most useful technique for intrawell comparisons is the combined Shewhart-CUSUM control chart. This control chart procedure is useful because it will detect releases both in terms of the constituent concentration and cumulative increases. This method is also extremely sensitive to sudden and gradual releases. A requirement for constructing these control charts is that the parameter is detected at a frequency greater than or equal to 25%, otherwise the data variance is not properly defined. The combined Shewhart-CUSUM control chart assumes that the data are independent and normally distributed with a fixed mean and a constant variance. Independent data is much more critical than the normality assumption. To achieve independence, it is recommended that data are collected no more frequently than quarterly to account for seasonal variation. The combined Shewhart-CUSUM control chart is extremely robust to deviations from normality. Because the control charts do not use a specific multiplier based on a normal distribution, it is more conservative to assume normality. It is recommended that at least eight rounds of data be available to provide a reliable estimate of the mean and standard deviation of the parameter concentration, although the control charts will be generated with as few as four data points. Having only four data points may produce greater uncertainty in the mean and standard deviation of the background data, leading to higher control limits, thus having a potentially high false negative rate. Many groundwater monitoring parameters are not detected at a frequency great enough to generate the combined Shewhart-CUSUM control charts. For constituents that are detected less than 25% of the time at a particular well, the data should be plotted as a time series until a sufficient number of data points are available to provide a 99% confidence nonparametric prediction limit. Thirteen independent measurements (with 1 resample) are necessary to achieve a 99% confidence (1% false positive rate) nonparametric prediction limit. Eight independent measurements (for pass 1 of 2 resamples) are necessary to achieve a 99% confidence nonparametric prediction limit. The nonparametric prediction limit is the largest determination out of the data set collected for that well and parameter. If the detection frequency is 0% after thirteen samples have been collected, the practical quantitation limit (PQL) becomes the nonparametric prediction limit. In developing the statistical background, the historical data must be thoroughly screened for anomalous data due to sampling error, analytical error, or simply by chance alone. An erroneous data point, if not removed prior to the mean and variance computations, would yield a larger control limit thus increasing the false negative rate. The DUMPStat® program screens for outliers using the Dixon test. If the Dixon test indicates an outlier, the value is compared to three times the median value for intrawell analyses. If the value fails both criteria of the two-stage screening, the value is considered a statistical outlier and will

not be used in the mean and variance determinations. Anomalous data will still be plotted on the graphs (with a unique symbol) but will not be included in the calculations. The verification resample plan is an integral function of the statistical plan to reduce the probability that anomalous data obtained after the background has been established, is indicative of a landfill release. The background data for each well and constituent is tested for existing trends using Sen's nonparametric estimate of trend. If contamination exists prior to completing the background, the control limits could be potentially high and this control chart method would not be able to detect an increasing trend unless the increase is severe. Results of the Intrawell Statistics for Detection Monitoring The trace metals and inorganic indicator data from wells MW-1N, MW-10N, MW-11N, MW-15, MW-16, MW-17, MW-19, MW-20, LGW-2, LGW-3R, LGW-4, LGW-8R, and LGW-14R were evaluated using the combined Shewhart-CUSUM control chart method. Assessment statistics were performed on the remaining wells due to previous control limit/prediction limit exceedances or VOC detections. The background used to determine control limits includes data obtained from January 2006 through 2012 for well MW-1N; January 2006 through 2014 for wells MW-10N, MW-11N, LGW-2, LGW-4; June 2015 through October 2106 for wells MW-15, MW-16, MW-17, MW-19, and MW-20; and February 2009 through 2014 for wells LGW-8R and LGW-14R. LGW-3R is a replacement well for LGW-3 and is in background monitoring. Upon completion of eight rounds of background, LGW-3R will be statistically evaluated. A summary of the intrawell statistics is included in Attachment C, Table 1 “Summary Statistics and Intermediate Computations for Combined Shewhart-CUSUM Control Charts.” The control charts or prediction limit graphs follow the summary table. Outliers identified on the control charts are summarized in the table below.

A control chart factor was selected to provide a balance of the site-wide false positive and false negative rates. A statistical power curve indicates the expected false assessments for the site as a whole. The site-wide false positive rate is 6% and the test becomes sensitive to 4 standard deviation units over background. Increasing trends detected in the background data include sulfate at MW-16, sulfate at MW-17, sulfate at MW-1N, and zinc at MW-1N. Monitoring well LGW-14R was resampled on October 2, 2018 and analyzed for TDS and zinc. The resample TDS concentration at LGW-14R (230 mg/L) confirms the initial exceedance at LGW-14R. The resample zinc concentration at LGW-14R (<5 μg/L) does not confirm the initial exceedance, therefore it is not statistically significant. Monitoring well MW-15 was resampled on October 2, 2018 and analyzed for sulfate. The resample sulfate concentration at MW-15 (11.0 mg/L) confirms the initial exceedance at MW-15. Monitoring well MW-1N was resampled on October 3, 2018 and analyzed for zinc. The resample zinc concentration at MW-1N (47.0 μg/L) confirms the initial exceedance at MW-1N.

STATISTICAL METHODOLOGIES FOR ASSESSMENT MONITORING Wells currently in assessment monitoring for past statistical exceedances or verified VOC detections include LGW-5, LGW-6, LGW-7, LGW-9, LGW-10, MW-2N, MW-3N, MW-7N, MW-8N, and MW-21. Volatile Organic Compounds VOCs detected in the ground water at Eco Vista Sanitary Landfill during the third quarter monitoring event in 2018 are summarized in the table below. Acetone was detected at wells LGW-10, LGW-7, LGW-9, MW-21, MW-2N, MW-7N, and MW-8N, however acetone was also detected in the associated equipment blank and trip blank at similar concentrations. The current acetone detections are likely artifacts of the sampling or analyses. Historical detections are summarized in Attachment B.

GWPS – Groundwater Protection Standard. Proposed in Document No. 65838 and approved in Document No. 65893. The current verified VOC detections were evaluated against the ground water protection standards (GWPS) using confidence limits (Attachment D). The 95% lower confidence limit (LCL) for the mean of the data was used to evaluate whether the regulated unit is in compliance with the approved ground-water protection standards (e.g. whether the verified constituent is detected at a significant level above the GWPS). An exceedance is verified if the LCL is above the Regulatory GWPS. The calculated LCLs for historically detected VOCs are below the respective GWPS. Trace Metals and Inorganic Compounds The current verified control limit/prediction limit exceedances and GWPS exceedances were evaluated against the approved GWPS using confidence limits (Attachment E). The 95% lower confidence limit (LCL) for the mean of the data was used to evaluate whether the regulated unit is in compliance with the groundwater protection standards (e.g. whether the verified constituent is detected at a significant level above the GWPS). An exceedance is verified if the LCL is above the GWPS. The 95% LCL for cobalt at LGW-10 (44.196 μg/L) exceeds the GWPS of 11 μg/L. The 95% LCL for cadmium at LGW-6 (57.541 μg/L) exceeds the GWPS of 5 μg/L. The 95% LCL for cadmium at LGW-7 (25.049 μg/L) exceeds the GWPS of 5 μg/L. The 95% LCL for cadmium at LGW-9 (34.045 μg/L) exceeds the GWPS of 5 μg/L. The 95% LCL for cobalt at MW-21 (14.467 μg/L) exceeds the GWPS of 11 μg/L.

The 95% LCL for cadmium at MW-3N (17.069 μg/L) exceeds the GWPS of 5 μg/L. The 95% LCL for cadmium at MW-8N (14.986 μg/L) exceeds the GWPS of 5 μg/L. The remainder of the calculated 95% LCLs are below the respective GWPS. CONCLUSIONS This document describes a comprehensive statistical plan designated for the Eco Vista Sanitary Landfill. The groundwater monitoring network for Eco Vista Sanitary Landfill includes wells MW-1N, MW-2N, MW-3N, MW-7N, MW-8N, MW-10N, MW-11N, MW-15, MW-16, MW-17, MW-19, MW-20, MW-21, LGW-2, LGW-3R, LGW-4, LGW-5, LGW-6, LGW-7, LGW-8R, LGW-9, LGW-10, and LGW-14R. These wells were sampled during July 10-17, 2018 and analyzed for the parameters required by permit. There are verified detections of 1,1-dichloroethane, 1,4-dichlorobenzene, benzene, and cis-1,2-dichloroethene at LGW-10, 1,4-dichlorobenzene at MW-21, and vinyl chloride at LGW-2. None of the VOCs exceeded GWPS. The trace metals and inorganic indicator data were statistically compared to background using control charts/prediction limits. For the most current data, there are verified statistical limit exceedances for TDS at LGW-14R, arsenic, iron, TDS, and TOC at LGW-2 and TDS at LGW-8R. Due to verified statistical limit exceedances, GWPS exceedances, and confirmed VOCs, select wells and parameters were evaluated using assessment statistics. The 95% LCL exceeded the GWPS for cobalt at LGW-10, cadmium at LGW-6, cadmium at LGW-7, cadmium at LGW-9, cobalt at MW-21, cadmium at MW-3N, and cadmium at MW-8N.

Attachment 2 — Revised Page 6, Second Half 2018 Groundwater Monitoring

Report

Groundwater Monitoring Report (Revised January 22, 2019) Eco-Vista Landfill, Arkansas 6

On June 12, 2014, a letter detailing the ongoing gas extraction efforts at the facility was submitted to ADEQ (Document 66045). Document 69516 “Approval of Plan for Modification to the Gas Extraction System at the Eco-Vista Landfill” was received on May 5, 2016. ADEQ approved the final nature and extent work plan (Documents 70569 and 70585) and well installation began in December 2016. The installation of the eight new nature and extent wells (NE-6 through NE-13) at the site was completed in December 2016 and a field activity report was submitted to ADEQ (Document 71488). Quarterly monitoring was conducted in 2017 and a report that discussed the findings of the nature and extent investigation was submitted to ADEQ on January 19, 2018 (Document 73049). As stated in the January 2018 report, current corrective action at the site is based on impacts to groundwater from landfill gas. Based on the results of the investigation, the CAMP for the facility will be updated and include representative sampling from select nature and extent wells to monitor the effectiveness of corrective action measures. Upon ADEQ approval of the January 19, 2018 report, the facility anticipates submitting the updated CAMP. Beginning with the First Half 2019 monitoring period, wells NE-6 through NE-13 will be sampled semi-annually (per Document 74554). In correspondence dated July 18, 2018, ADEQ issued comments (Document 74217) on the Nature and Extent Report (Document 73049). In correspondence dated September 12, 2018, FTN issued a response (Document 74554) to the ADEQ comments. In correspondence dated September 28, 2018, ADEQ issued a response (Document 74635) to FTN’s comments. The site is currently compiling a Nature and Extent Investigation Work Plan to address the ADEQ comments.

7.0 CONCLUSIONS The following conclusions are based on the results of the Second Half 2018 groundwater sampling events and analytical testing: Groundwater Flow The water level data for the third quarter (July 2018) and fourth quarter (October 2018) sampling events indicated that the groundwater flow direction within the uppermost aquifer was to the southeast across the site, consistent with past events. The groundwater flow rate was 1.43 feet/day (July 2018) and 1.43 feet/day (October 2018), consistent with past events. Analytical Results The GWPSs were exceeded for cobalt at MW-21, LGW-10, and NE-5; and cadmium at MW-3N, MW-8N, LGW-6, LGW-7, and LGW-9 during the July 2018 and October 2018 events, consistent with recent events. During the July 2018 event, VOCs were detected above the PQLs at quantified concentrations at MW-21, LGW-10, and NE-5, consistent with past events. Vinyl chloride was detected for the first time at LGW-2 during the July 2018 event. None of the July 2018 VOC detections exceeded a GWPS. Acetone was detected at quantified concentrations at various wells; however, was also detected in the Equipment Blank and Trip Blank 1. Acetone is a known laboratory contaminant and may represent a laboratory artifact. During the October 2018 event, VOCs were detected above the PQLs at quantified concentrations at LGW-2, LGW-10, and NE-5. Acetone was detected at quantified concentrations at various wells but was also detected at quantified levels in the Equipment Blank and laboratory Method Blank. With regards to acetone detections, as noted above, acetone is a known laboratory contaminant and may represent a laboratory artifact. The VOC detections at LGW-10 and NE-5 were consistent with previous events. Vinyl chloride was verified detected at LGW-2 during the October 2018 event.
