(Pitt County, NC) NC Solid Waste Permit #74-07 Dear Ms. Drummond: On behalf of C&D Landfill, Inc., SCS Engineers, PC (SCS) is pleased to present this Source Demonstration at the referenced facility. The Facility entered into Assessment Monitoring in late 2009 (second semi-annual monitoring event) after negotiating an Appendix II sampling protocol based on a preliminary characterization of a ground water impact. The impact appears to focus on an old drainage ditch excavated for prior agricultural use of the site. The detected constituents from the Appendix I sampling list, which triggered the Assessment in accordance with 15A NCAC 13B .0545, appeared to consist of petroleum hydrocarbons and pesticides. Initial site permitting, beginning ca. 2000, and subsequent monitoring oversight was provided by David Garrett & Associates, who initiated the Assessment program. In summary, benzene and vinyl chloride appear to be the only lingering constituents of concern. As both can be monitored using Appendix I protocols, SCS recommends the C&D Landfill be allowed to revert to Appendix I monitoring and the trends for benzene and vinyl chloride will continue to be monitored. Natural attenuation of the ground water impact, with continued monitoring as appropriate, appears to be the appropriate remedial measure. Please contact us if you have any questions regarding this report. Sincerely, Donald M. Cobb, PG Steven C.

Phase 1A of the CDLF opened in 2001, following site characterization studies performed ca. 2000 that characterized the ground water flow conditions. Subsurface conditions within the upper 70 feet consist of two relatively sandy aquifers (fluvial and shallow marine sediments) separated by a partial confining layer (deep marine silt-clay associated with the Yorktown Formation). An upward hydraulic gradient exists beneath much of the site due to mild artesian pressure within the deeper aquifer. Phase 1B opened ca. 2005, and Phase 2 started operation in 2009. Phase 1 covers approximately 15 acres. Ground water is shallow, typically within 5 feet beneath the surface, and is directed to the south, toward large receiving streams (Grindle Creek and/or the Tar River). The downgradient area between the facility and the streams is mostly within the 100-year floodplain and contains extensive wetlands. Grindle Creek has a class C-NSW stream designation (fresh water, supportive of aquatic life and recreation, nutrient sensitive). The nearest receiving streams are not blue-line features. There are no ground water users located down-gradient of the facility and virtually no down-gradient development potential exists. The surrounding area is served by public water supply, derived from wells but which are miles away and upgradient. Past uses of the site include agriculture and recreational hunting and four-wheeling – activities which are potential sources of some of the contaminants observed in excess of the 2L and Solid Waste Section Limits (SWSL) standards. The initial waste material brought to the facility was Hurricane Floyd flood damaged demolition debris, which was collected under emergency management conditions. That is, materials not normally admitted to a CDLF under the Solid Waste regulations may have been introduced and/or one or more historic spills near a drainage feature in a remote corner of the site, southwest of Phase 1, may have caused the impact. Ground water monitoring did indicate certain inorganic background constituents – not the focus of this assessment – which are exacerbated by turbidity. The organic constituents have been detected only sporadically. The Facility entered into Assessment Monitoring in late 2009 (second semi-annual monitoring event) after negotiating an Appendix II sampling protocol based on a preliminary characterization of a groundwater impact. The impact appears to focus on an old drainage ditch excavated for prior agricultural use of the site. The detected constituents from the Appendix I sampling list, which triggered the Assessment in accordance with 15A NCAC 13B .0545, appeared to consist of petroleum hydrocarbons and herbicides. At this time the Assessment Monitoring has shown no new constituents in the groundwater, and the data appear to support the initial presumption regarding the source of the contaminants. Groundwater Source Demonstration 2 1.2 ASSESSMENT MONITORING A summary of the detected constituents in groundwater that triggered the Assessment Monitoring, which were discussed in the 2009 Assessment Work Plan, is provided in Table 1.

A full record of groundwater sampling data back as far as SCS was reasonably able to obtain as part of this investigation is included in Attachment B. Significant trends relative to the Assessment Monitoring are as follows: Groundwater Source Demonstration 3 • Benzene is holding steady just slightly above the 2L and SWSL standards at MW-3S, detected above 2L and SWSL only once at MW-3A, and detected sporadically with recent non-detects at MW-8. • Constituents listed on the pre-assessment detection list, but are no longer listed, i.e., these have not been detected since the database was updated by SCS, include Chloroethane, Chloromethane, and 1,2-Dichloroethane. • Vinyl chloride has been consistently detected in well MW-12 above the 2L and SWSL standards. 2.0 FIELD INVESTIGATION 2.1 SAMPLING LOCATIONS Seven (7) test pits, designated TP-01 through TP-07, were excavated for soil sampling and in situ observations, with one serving as a background reference point. The test pits were excavated to depths between 48 and 64 inches. An additional six (6) test pits, designated TP-08 through TP-13, were excavated in an attempt to delineate the extent of contamination using field measurements obtained with a photoionization detector (PID). No soil samples were collected from locations TP-08 through TP-13. Test pit locations are shown on Figure 1 in Attachment A. 2.2 TEST PIT SAMPLING In order to establish a baseline of volatile organic compounds (VOCs) and metals present in the soils at the Site, SCS identified an area from which to collect a “clean” soil sample located outside the limits of the drainage feature suspected to be the source of contamination. This location is denoted as TP-07 on Figure 1. Using a RAE Systems MiniRAE 3000 PID, SCS obtained a background reading of VOCs present in native soil and collected a sample from this “clean” soil for laboratory analysis. No waste was observed during excavation of any test pit. Further, no staining of any sort was observed in any test pit. Soil excavated from within the drainage feature had a swampy odor; soil excavated from outside the drainage feature did not exhibit any noticeable odors. At TP-01 through TP-07, SCS obtained readings with the PID at the depth which soil samples were collected. These readings, as well as the test pits analyzed solely with the PID (TP-08 through TP-13) are summarized in Table 2: Groundwater Source Demonstration 4 Table 2 – PID Readings Location ID Depth (bgs) VOCs (ppm) TP-01 4 ft. 0 TP-02 6 ft. 0.4 TP-03 5.5 ft. 0 TP-04 5.5 ft. 0 TP-05 6 ft. 0 TP-06 4.5 ft. 4.2 TP-07 4.5 ft. 0 TP-08 4.5 ft. 0 TP-09 4.5 ft. 0 TP-10 4.5 ft. 0 TP-11 3 ft. 4.5 ft. 6 ft. 0 0 0 TP-12 5 ft. 0 TP-13 5 ft. 0 Three PID readings were taken at location TP-11 as this location is approximately halfway between TP-06, where the highest VOC reading was obtained, and the landfill. The purpose of these extra readings was to explore whether contamination was coming from the landfill. Sampling occurred at each location within the vadose zone at depths between four and six feet below ground surface (bgs), except for location TP-06 wherein PID readings indicated the presences of hydrocarbons above the vadose zone at a depth of 4.5 ft. bgs. 3.0 LABORATORY ANALYSIS The samples collected from each test pit were analyzed with EPA Method 8260B, Volatile Organic Compounds. This method covers all detected constituents listed above, with the exception of Dinoseb and Silvex, both herbicides. To assess the presences of these two constituents, samples were analyzed with EPA Method 8251A, Chlorinated Herbicides. The results of the laboratory analyses are summarized in Table 3. Only analytes detected as present are listed; the full laboratory results can be found in Attachment C. Included in Table 3 are the non-underground storage tank (UST) Soil-to-Water Maximum Contaminant Concentrations, Residential Soil Cleanup Levels, and Industrial/Commercial Soil Cleanup Levels, all in mg/kg. No herbicides were detected in any samples above the method detection limit.

All concentrations given in soil mg/kg. 2. J denotes concentrations detected below reporting limit. 3. ND - Not detected 4.0 DISCUSSION Acetone is a both a manufactured and naturally-occurring compound. The samples with the highest concentrations of acetone, taken from test pits TP-02, TP-03, TP-04, and TP-05, were collected within the drainage feature, wherein the ground was swampy with an abundance of plant life. This, combined with concentrations well below the 2L and SWSL standards, indicates that the acetone detected in the test pits is likely naturally-occurring and does not originate from the Landfill. Benzene is present in many petroleum products, such as fuels and solvents, and is a very common environmental contaminant. Benzene was detected in MW-3S at a concentration of 2.1 µg/l, which exceeds the 2L and SWSL standards of 1.0 µg/l but is below the Maximum Groundwater Source Demonstration 6 Contaminant Level of 5.0 µg/l. Benzene detected in test pits TP-03, TP-4, and TP-5 are well below the Soil-to-Water Maximum Contaminant Concentration of 0.0056 mg/kg. Further, all detections of benzene in the test pit samples have a “J” qualifier, indicating that the listed concentration is below the reporting limit but greater than or equal to the method detection limit and are approximate values. A possible vector for VOC contamination in the vicinity of the MW-3 cluster of wells, corresponding to TP-06, is the past presence of a camp site near the center of the cluster. Site personnel have confirmed that parts of the site have been used for recreational hunting, and past agricultural practices occurred extensively on the premises. It is possible that, at some point fuel may have been spilled in this area. This would at least partially explain the detected presence of VOCs, as measured by the PID, at a higher elevation relative to the water table and vadose zone in TP-06 as compared to the other test pits. No herbicides were detected in any sample above the method detection limit. Dinoseb is considered stable in water. Dinoseb was originally registered for use in 1948. In 1986, EPA suspended commercial use of Dinoseb. These factors, and the former agricultural use of the site, indicate that the Dinoseb detected in MW-3S pre-dates the presence of the landfill, which opened in 2001. EPA cancelled all registered uses of Silvex on January 2, 1985. Silvex is believed to degrade slowly in water. These factors, and the former agricultural use of the site, indicate that the Silvex detected in MW-3S pre-dates the presence of the landfill, which opened in 2001. Although no vinyl chloride was detected in the soil samples collected as part of this investigation, it has been consistently detected in MW-12. Vinyl chloride is near the end of the degradation chain of trichloroethylene (also known as trichloroethene or TCE) and tetrachloroethylene (tetrachloroethene, perchloroethylene, or PCE). Both TCE and PCE have been historically detected in MW-12, though the most recent detected was May 2012 for TCE and May 2011 for PCE. In all cases, TCE and PCE detections were marked with a “J” qualifier, indicating the detection was below the reporting limits. 5.0 CONCLUSIONS AND RECOMMENDATIONS The data collected during this investigation shows a low-level of benzene contamination in the soils around test pits TP-03, TP-4, and TP-05. Benzene contamination in groundwater has been detected in the MW-3 monitoring well cluster (MW-3A, MW-3D, and MW-3S) and well MW-8. Groundwater flow in this area of the Landfill is generally to the southwest. It is possible that soil contamination in the vicinity of test pits TP-03, TP-04, and TP-05 is transported to MW-8 and the MW-3 cluster. Further, benzene has not been detected in monitoring well MW-11 at any concentration above the detection limit; MW-11 is located in close proximity and hydraulically upgradient of both TP-03 and MW-8. Another factor to consider is that PID readings of test pits TP-02 and TP-06 showed VOC concentrations of 0.4 ppm and 4.2 ppm, respectively. TP-02 is located hydraulically upgradient of both MW-8 and TP-03 and at least hydraulically cross-gradient, if not upgradient, of TP-04 and TP-05. As such, it is possible that contamination above the vadose zone in the vicinity of TP-02 could be transported downgradient to MW-8 and the MW-3 cluster. Groundwater Source Demonstration 7 The PID reading in test pit TP-06 was substantially higher than that measured in TP-02. Further, VOCs were detected above the vadose zone in TP-06. No VOCs were detected at any of three depths in TP-11, located approximately equidistant from the Phase 1 footprint and the MW-3 cluster, nor in TP-08, located approximately equidistant from MW-3D and MW-3S. As previously discussed, this area of the Landfill was previously used as a campsite. A release of gasoline, diesel fuel, kerosene, or similar fuels localized to the vicinity of TP-06, and thus the MW-3 cluster, provides one possible explanation for the consistent detection of benzene in MW- 3S. The low level of benzene contamination must also be considered. The levels detected in the test pits are well below Soil-to-Water Maximum Contaminant Concentration for a non-UST petroleum release, and are substantially below the Residential and Industrial/Commercial soil cleanup levels. Also, the benzene levels detected in wells MW-3A, MW-3S, MW-3D, and MW- 8, when present, are only just above the 2L and SWSL standards and below the Maximum Contaminant Levels for drinking water. Finally, there are no known receptors located within 1000 feet of the impacted wells, and beyond this distance, natural attenuation is likely to reduce the benzene concentration to below the 2L standard. No vinyl chloride was detected in any of the soil samples. However, vinyl chloride has been consistently detected in MW-12. A review of the available historical data shows that TCE and PCE have been previously detected in MW-12. As discussed above, vinyl chloride is near the end of the degradation chain of these compounds. Vinyl chloride also biodegrades, albeit at a slower rate than TCE or PCE. Degradation of TCE and PCE may account for the subsequent increase in vinyl chloride detected in MW-12. Since benzene and vinyl chloride appear to be the only lingering constituents of concern, and since both of these constituents can be monitored using Appendix I protocols, it is recommended that the Landfill be allowed to revert to Appendix I monitoring and the trends for benzene and vinyl chloride will continue to be watched. Based on our understanding of the data, it appears that conditions are appropriate for natural attenuation of the ground water impact with continued monitoring as an appropriate remedial measure. If future Appendix I data show different trends from those now recognized, further recommendations will be considered.

Receipt The samples were received on 3/31/2016 9:50 AM; the samples arrived in good condition, properly preserved and, where required, on ice. The temperature of the cooler at receipt was 5.7º C. GC/MS VOA Method(s) 8260B: The laboratory control sample (LCS) for batch analytical batch 490-328386 recovered outside control limits for the following analytes: Chloroethane. These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. Method(s) 8260B: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with analytical batch 490-328386. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GC Semi VOA Method(s) 8151A: The %RPD between the primary and confirmation column exceeded 40% for Dichloroacetic acid(Surr) for the following samples: TP-07 (490-100651-7). The lower value(s) has been reported and qualified in accordance with the laboratory's SOP. Method(s) 8151A: The laboratory control sample (LCS), laboratory control sample duplicate (LCSD), matrix spike (MS), and matrix spike duplicate (MSD) for preparation batch 490-329808 and 490-329808 and analytical batch 490-330196 recovered outside control limits for the following analyte: Dinoseb. This compound has been identified as a poor performing analytes when extracting using this method; therefore, re-extraction/re-analysis was not performed. These results have been reported and qualified. Method(s) 8151A: Preparation batch 490-329161 is reported without a matrix spike/matrix spike duplicate (MS/MSD). The batch MS/MSD was originally performed on a sample which required re-extraction and re-analysis. The associated laboratory control sample (LCS) met acceptance criteria and provides long-term precision and accuracy for this batch. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. Organic Prep No analytical or quality issues were noted, other than those described in the Definitions/Glossary page. VOA Prep No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.
