January 2018 1 1.0 INTRODUCTION On behalf of Burke County, Joyce Engineering (JOYCE) prepared this second Addendum to the Corrective Action Plan (CAP Addendum #2) for the Johns River Waste Management Facility (facility). This is the second addendum since the original CAP was submitted in June 2008. The first CAP Addendum, dated August 2013, was prepared in in response to the Groundwater Protection Standard (GPS) exceedances of volatile organic compounds (VOCs) in piezometers on the northeast side of the landfill. VOCs in exceedance of GPS include: 1,1-dichloroethane; 1,2- dichloroethane; 1,4-dichlorobenzene; benzene; methylene chloride; tetrachloroethene; trichloroethene; and vinyl chloride. The impacted piezometers are located upgradient of the existing waste unit and the exceedances are believed to be the result of cross-media impact to the groundwater by migrating landfill gas (LFG). The 2013 Addendum added control of migrating LFG as a remedial method for the area northeast of the active landfill. The 2013 Addendum proposed installation of several passive gas vents and included as a contingency the option to add a gas extraction unit (GEU) to convert the passive vents into an active gas extraction system. This Addendum #2 has been prepared in response to a March 27, 2017, letter from the North Carolina Department of Environmental Quality (NCDEQ), Division of Waste Management (DWM), Solid Waste Section (SWS), which requested that Burke County implement the contingency. This CAP Addenda has been prepared in accordance with 15A NCAC 13B.1636 of the North Carolina Solid Waste Management Rules (NCSWMR). Note: the NCDEQ was formerly called the Department of Environment and Natural Resource (DENR), and is referenced as such in some parts of this report. 1.1 Site Background The Johns River Waste Management Facility is located in the north-central portion of Burke County, north of Morganton, North Carolina. The 318-acre landfill property is bounded by Lower Creek to the north and east, and the Catawba River to the south. The Johns River flows into the Catawba River near the southwest corner of the landfill property. The Catawba River forms the upper reaches of Lake Rhodhiss along the southeastern property line. The property boundaries are indicated on an excerpt from the USGS topographic quadrangle for Morganton, North Carolina (Figure 1). The site has rolling topography with elevations ranging from 995 feet to 1,160 feet above mean sea level (AMSL). The central portion is generally gently sloping and contains the higher elevations; relatively steep slopes and significant drainage features are located around the perimeter. Properties within 2,000 feet of the landfill boundary are covered by surface water or are heavily wooded. The unlined waste disposal unit consists of 28 acres in the southwest corner of the landfill property. The municipal solid waste (MSW) Landfill began operation in April 1988, but was closed to comply with Rule .1627(c)(10)(A) of the NCSWMR, a regulation governing MSW Landfills units Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 2 that were not designed with a base liner and leachate collection system. Burke County operated a permitted Construction and Demolition (C&D) disposal area on top of the closed portions of the MSW landfill between 1998 and 2015 under Permit # 1203-CDLF-1998. Closure construction for the C&D area was completed in 2016, and the closure was certified by the DEQ in February 2017. A MSW transfer facility is located in the eastern half of the property. The transfer station has operated since 1998 under permit #1205T-TRANSFER-1998. In 2012, JOYCE submitted a Site Plan Application and a Permit to Construct Application for an expansion of the C&D landfill to new cells located northeast of the existing landfill. A Permit to Construct for Phase 1A was issued in March 2014 and the County completed construction of Phase 1A of the C&D landfill expansion in July 2014. A Permit to Operate for Phase 1A was issued to the County by the North Carolina Department of Environment and Natural Resources, now the Department of Environmental Quality (NCDEQ), on August 14, 2014. The C&D Expansion operates under Permit # 1203-CDLF-2014. A site plan showing all the pertinent features of the existing and proposed landfills and associated facilities, as well as the December 2012 groundwater potentiometric contours and flow directions, is provided as Drawing 1. 1.2 Corrective Actions to Date In February 2005, in response to Groundwater Protection Standard (GPS) exceedances of several volatile organic compounds (VOCs), including benzene,1,4-dichlorobenzene, methylene chloride, tetrachloroethylene, and trichloroethylene at the facility, Burke County submitted an Assessment of Corrective Measures (ACM) for the Johns River Landfill to the DENR. The ACM presented an analysis of the effectiveness, performance, reliability, ease of implementation, and potential environmental impacts of potential remedies, including safety impacts, cross-media impacts, and residual contamination exposure control. The ACM also addressed the time required to implement and complete the remediation, the costs of implementation and maintenance, and the institutional requirements such as State or local permit requirements or other environmental or public health requirements that may substantially affect the implementation of the potential remedies. Based on the ACM, four remedial alternatives were selected for further consideration. The four selected remedies were: • Monitored Natural Attenuation with Phytoremediation; • Control of Decomposition Gases (LFG); • Enhanced Bioremediation; and • Soil Vapor Extraction (SVE). In June 2008, the County submitted a Corrective Action Plan (CAP) for the facility, which proposed Monitored Natural Attenuation and Phytoremediation as the selected remedies for the site. The CAP was approved by DENR in a letter dated January 29, 2009. The first Corrective Action Evaluation Report (CAER) for the facility was submitted to DENR in May, 2011. Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 3 The Facility entered the Corrective Action Program following the correspondence received from the DENR Solid Waste Section (SWS) dated August 18, 2003. An Assessment of Corrective Measures (ACM) was submitted to NCDEQ in February 2005. A public meeting was held on May 16, 2006 in order to receive public comments regarding the ACM as required by NCSWMR §.1635 (d). A Corrective Action Plan (CAP) was submitted to DENR in June 2008 and revised in November 2008. The CAP was approved by DENR in a letter dated January 29, 2009. An addendum to the facility’s CAP was submitted to the DENR in August 2013, adding control of landfill gas as a remedy for groundwater impacts on the northeastern side of the landfill between the old landfill and the new C&D expansion area. The 2013 CAP Addendum proposed installation of eight passive gas vents in the MSW waste along the northeast side of the old C&D-over-MWS landfill, between the old landfill and the C&D Expansion Area. In November 2013, JOYCE installed seven passive gas vents at the locations shown on Drawing 5. One of the originally-proposed eight vents turned out to be located on C&D waste and could not be installed. In September 2015, four additional passive gas vents were installed along the top of the landfill as part of closure construction for the C&D portion of the old landfill. The locations of these vents are also shown on Drawing 5. In a letter dated March 27, 2017, the NCDEQ-SWS requested implementation of the County’s corrective action contingency plans, and asked for a proposed alternate remedy and implementation schedule within 90 days. We requested an extension of the due date for our response to July 25, 2017, which was approved in an email dated June 12, 2017. A Proposed Alternate Remedy and Schedule for implementation of an active landfill gas control system was submitted to NCDEQ on July 25, 2017. After reviewing it, the NCDEQ requested some changes to the schedule, and a revised Proposed Alternate Remedy and Schedule was submitted on August 15, 2017. 1.3 Gas Impacts and GPS Exceedances Northeast of the Landfill LFG monitoring has been performed quarterly at the Johns River Landfill since 1993. Since 1994, there have been notable exceedances of the lower explosive limit (LEL) for methane in gas probe GP-2. Gas monitoring probes GP-2S, GP-2I, and GP-2D are nested probes in a single boring that are jointly referred to as GP-2. GP-2 is located near the northeastern corner of the existing landfill, less than 100 feet from the limits of waste and far from any property boundary. Probe GP 1 adequately monitors the nearest property boundary to GP-2, and all other property boundaries are over 2000 feet away and/or are bounded by surface water. The DENR has previously agreed that the exceedances at GP-2 do not indicate methane migrating across or toward a facility boundary (see correspondence between JOYCE and the DENR dated October 6, 2011). There have never been any methane exceedances at any other gas probes or in any structures at the Johns River facility. Concern about LFG exceedances in the vicinity of GP-2 were elevated during the DENR review of the County’s permit application for the C&D expansion to the northeast of the existing landfill. At the DENR’s request, JOYCE conducted a LFG delineation study in the vicinity of GP-2 in November 2012. The results of the LFG delineation study are shown in Drawing 2. The area of Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 4 methane concentrations above the LEL extends 200-350 feet from the edge of waste northeast of the existing landfill, which includes the southwestern portions of the proposed expansion area Phases 1, 2, and 3. LFG is typically composed of roughly 55% methane, 44% carbon dioxide, and 1% other VOCs. It is not uncommon for VOCs in LFG to partition into the ground water where the migrating gas comes into contact with the groundwater. This can happen inside wells, in the vadose zone, or at the groundwater surface. LFG impacts to groundwater have been suspected at the Johns River Landfill in the past. Former upgradient background monitoring wells MW-9 and MW-17, located north of existing waste unit, both exhibited detections of VOCs that were attributed to LFG prior to their being removed from service as background wells. In February 2013, at the DENRs request, JOYCE sampled existing piezometers in the vicinity of the area of methane migration northeast of the existing landfill to determine the extent of groundwater impacts in this area. JOYCE sampled Piezometers PZ-30S, PZ-35, PZ-36, PZ-37, and PZ-38. PZ-36 and PZ-38 are located between the old waste unit and Phase 1 of the proposed C&D expansion. PZ-38 has been designated to become compliance monitoring well MW-23 under the Water Quality Monitoring Plan (WQMP) submitted in August 2012 with the permit-to –construct application for the C&D expansion. PZ-30S, and PZ-35, and PZ-37 are located with the proposed footprint of the C&D expansion. The results of the February 2013 piezometer sampling event were submitted to the DENR in a letter report dated April 23rd, 2013. Results of the February 2013 piezometer sampling indicated several VOCs in exceedance of their respective GPS, including: 1,1-dichloroethane; 1,2-dichloroethane; 1,4-dichlorobenzene; benzene; methylene chloride; tetrachloroethene; trichloroethene; and vinyl chloride. The exceedances were in piezometers PZ-36 and PZ-38, which are located between the existing waste unit and the proposed expansion unit. No VOCs were detected in any of the piezometers located within the footprint of the proposed expansion unit. After reviewing the results of the February 2013 piezometer sampling, the DENR requested two more piezometers be sampled. JOYCE sampled Piezometers PZ-31 and PZ-34 on July 18, 2013. PZ-31 and PZ-34 are located between the piezometers with exceedances (PZ-36 and PZ-38) and the piezometers that were clean (PZ-30S, PZ-35, and PZ-37). The results of the July 2013 piezometer sampling event were submitted to the DENR in a letter report dated July 29th, 2013. Table 1 presents the detected VOCs from the February 2013 and July 2013 piezometer sampling events. Table 2 presents the detected VOCs from the December 2012 semiannual compliance monitoring event. These combined results were used to create the Total VOC Isoconcentration Map shown in Drawing 3. Drawing 4 shows a cross-sectional view of the Total VOC plume. Drawings 3 and 4 show that the highest concentrations of VOCs in the groundwater are in PZ-36, the piezometer closest to GP-2, where the highest methane concentrations are. The VOC plume extends beneath a portion of the Phase 1 footprint in the vicinity of PZ-31. In general, the concentrations of VOCs to the northeast of the existing landfill closely mimic the concentrations of methane in the subsurface. This supports the contention that the VOCs in the groundwater in this area are primarily due to partitioning from the LFG. Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 5 Figure 2 presents a series of charts showing the concentrations of the constituents of concern in MW-36 and MW-38 vs. time from February 2013 through December 2016. The charts show decreasing trends in the concentrations of the COCs since the installation of the gas vents in November 2013. There is evidence that the remedy is reducing the concentrations of COCs in MW-36 and MW-38; therefore, the remedy is working effectively as designed. 2.0 ADDITIONAL REMEDY - CONTROL OF LANDFILL GAS 2.1 Landfill Gas Impact on Groundwater Typically, LFG is made up of approximately 55% methane, 44% carbon dioxide, and 1% other VOC’s, including vinyl chloride and benzene (Allen, et al, 1997; Deipser and Stegmann, 1994; Cowie, 2004). Numerous studies have established that VOC’s present in LFG can readily partition into groundwater. Transfer of VOC’s from gas to groundwater can occur both in the monitor well and/or outside the monitor well. LFG is the most likely source of VOC detections in groundwater located cross-gradient from the landfill The 2005 ACM for this facility concluded that control of decomposition gas (LFG) was an appropriate and viable remedy for groundwater impacts at the Johns River Facility. It is likely VOC exceedances northeast of the existing landfill are related to LFG; therefore, control of LFG migration is an appropriate remedy to address groundwater impacts for this area. 2.2 Passive LFG Control Mechanism The proposed mechanism for control of LFG in the 2013 CAP addendum was installation of passive gas vents in the MSW waste along the northeastern portion of existing landfill, spaced approximately 100 feet apart. The old waste unit consists of a closed MSW landfill with C&D waste on top of it. Seven vents were installed in November 2013 in the MSW waste just beyond the limits of the C&D waste. Locations of the vents are shown on Drawing 5. The vents were installed to the base of waste as determined during drilling. The following table summarizes the total depths (in feet below grade) for each of the seven gas vents installed in 2013: Gas Vent: GV-1 GV-2 GV-3 GV-4 GV-5 GV-6 GV-7 Total Depth: 25.5’ 35.0’ 43.0’ 43.0’ 45.0’ 47.0’ 36.0’ The vents were constructed of perforated 6 inch PVC well screen and riser screened from 5 feet below grade to total depth. The borings were back-filled with gravel to 1 foot above the top of screen, and a minimum 2-foot bentonite seal was placed above the gravel pack. The vents were completed approximately feet above grade and topped with solar turbine heads. Vent construction logs for the seven vents installed in 2013 are included in Appendix A. In September 2015, four additional passive gas vents were installed along the top of the landfill as part of closure construction for the C&D portion of the old landfill. These vents are only in C&D waste and do not penetrate to the MSW waste beneath it. They were not installed as part Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 6 of the remedy for groundwater impacts by landfill gas; however, they may provide some additional gas control that is beneficial to groundwater corrective action. The locations of these vents are also shown on Drawing 5, and their total depths are summarized below: Gas Vent: GV-8 GV-9 GV-10 GV-11 Total Depth: 34.0’ 24.0’ 24.0’ 24.0’ 2.3 GEU Pilot Tests GEU pilot tests were conducted on September 25-26, 2017, to determine the optimal vacuum and flow rates for the proposed permanent GEU. Tests were conducted independently on three of the seven original passive gas vents, GV-4, GV-2, and GV-6. A 2.0 HP portable GEU was used for the pilot tests, with vacuums ranging from -10 to -25 inches of water column (in-wc). A GEM- 2000 was used to measure gas concentrations, pressures, etc., on the tested vent throughout each test, and manual measurements were made periodically at the vents on either side of the tested vent (i.e., on GV-3 and GV-5 for the test on GV-4). The data from the pilot tests was used to constraining the design of the active gas extraction system. The data from the pilot test are presented in Appendix B. 2.4 Active LFG Control Mechanisms In order to control landfill gas migration and lessen cross-media impacts to the groundwater, the passive vents will be converted to an active LFG system with the installation of a gas extraction unit (GEU) and connected to the existing passive vents through a below grade piping system. The proposed layout and details for the GEU and piping system are shown on Drawings 5 and 6, and specifications are included in Appendix C. 2.4.1 GEU The gas extraction unit (GEU) will be a prefabricated, skid mounted unit including: centrifugal blower, condensate knockout tank and air filter. A flare will be installed if odor or emissions control is determined to be necessary. Sufficient area will be left on the skid to allow for flare installation at a later date. Design specifications for the GEU are provided in Appendix C. The GEU shall have a design rating of 140 SCFM at -15 in. w.c, corresponding to an average of 20 SCFM per vent. Typically a system pressure of approximately -10 to -15 in. w.c is desired throughout the collection piping. The gas extraction system was modeled using KYGAS Pipe2018 Gas Network Analysis Software by KYPIPE LLC to determine the necessary vacuum to be supplied by the blower to maintain between -10 and -15 in. w.c at each well. Landfill gas input parameters such as specific gravity, absolute viscosity, density, and molecular weight were estimated by averaging the corresponding values for methane and carbon dioxide assuming a 50%-50% composition in landfill gas. Standard pipes with 4” and 8” internal diameters were used in the model for laterals and header pipes, respectively and assigned a length corresponding to the plan view of the gas extraction system shown on Drawing 5. A default pipe roughness value of 120 millifeet was Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 7 assigned to the modeled pipes. Fittings (elbows, tees, valves) and entrances were incorporated into the model to account for additional losses. Each well node was assigned a flow demand of 20 SCFM. The model demonstrated that -15 in. w.c being supplied at the blower was sufficient to maintain between -10 and -15 in. w.c at each of the wells with the lowest well vacuum value being -14.1 in. w.c. The output report from the KYGAS modeling is provided in Appendix D. A variable frequency drive (VFD) rated electric motor capable of operating with the available single-phase power at the site may be used. If an electric motor requiring 3-phase power is selected, power will need to be brought in to the proposed GEU location from elsewhere on site, or from off-site, if necessary. 2.4.2 Wells Wells will be connected to the gas system using 2” flex hose. A 2” ball valve will be installed between the well head and the flex hose in order to control flow and isolate the wells. A detail showing this well configuration is shown on Drawing 5. 2.4.3 HDPE Pipe & Fittings The gas collection piping shall include an 8” diameter header and 4” diameter lateral lines connecting the header to each gas vent. The header and lateral lines shall be SDR 17 HDPE. The proposed generalized layout of the pipe system is shown on Drawing 5. A detail of the trenching of the landfill gas pipes is also provided on Drawing 5. If the header must cross beneath any roads or areas where vehicles or equipment may need to drive over it, the HDPE pipe shall be encased in a corrugated metal protective sleeve. A cleanout is provided at the end of the header line to allow access to flush or camera the pipes if necessary in the future. Connections of the collection pipe to the wells shall be accomplished with flexible fittings and flex hose, as shown in the detail on Drawing 5. Specifications for the piping, trenching, and connections are included in Appendix C. 2.4.4 Condensate Removal The pipe system shall have a minimum slope of 2% for drainage of condensate to a single condensate trap/sump at the northern, or low, end of the header. A 4” HDPE drain line allows condensate to gravity drain from the header to the trap/sump, with a “J” trap in the sump to maintain the vacuum on the header. The sump will consist of a buried HDPE tank of approximately 4’ diameter by 10’ deep (930 gallons). Based on a conservative condensate generation rate of 0.77 gallons per 1000 CFM of raw landfill gas (Municipal Landfill Gas Condensate, EPA/600/S2-87/090, 1988) and an expected gas system flow rate of 140 CFM, the 930 gallon tank will have a storage capacity of approximately 5.8 days. The tank will have access from the surface for periodic pumping out of the condensate, and for maintenance. Condensate from the knockout pot of the GEU will be designed to gravity drain back to the condensate sump. A detail drawing of the condensate sump is provided Drawing 6 and specifications are included in Appendix C. Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 8 2.4.5 Operation and Maintenance Operation and maintenance of the active LFG system will include: 1) “wellfield”; 2) the GEU; and 3) the condensate sump. The wellfield will be balanced by adjusting the flow at each well to provide an even distribution of flow and maintain appropriate vacuum throughout the system. The well field will be balanced at startup and as necessary thereafter to achieve and maintain optimum system performance. The GEU will be designed to run 24 hours per day, 7 days per week in an outdoor setting. The GEU will require periodic lubrication of the blower, replacement of the air filter, and inspection of the knockout tank to insure proper functioning. The GEU should be checked daily for the first week of operation, and at a minimum, weekly thereafter. A maintenance log for the GEU should be maintained on site. The condensate sump should be checked weekly, at a minimum, and more often if necessary, to gauge the level of condensate in the tank, and be sure the tank remains in good condition is operating properly. When the condensate sump is approaching capacity, the condensate should be pumped out and transported to an appropriate facility for proper disposal. 2.4.6 Odor Control If odor from the landfill gas becomes an issue, a utility flare may be added to the GEU to combust the landfill gas. In the event this becomes necessary, the County will submit details for the design and installation of the flare to DEQ for approval prior to proceeding. 3.0 REMEDY EVALUATION FACTORS 3.1 Long-Term and Short-Term Effectiveness According to 15A NCAC 13B.1636(c)(1), the County is required to evaluate the long-term and short-term effectiveness and protectiveness of the potential remedy, along with the degree of certainty that the remedy will prove successful based on consideration of several factors. These factors are addressed below. 3.1.1 Magnitude of Reduction of Existing Risks Existing risk at the facility is limited to environmental professionals and/or County employees participating in compliance groundwater or LFG monitoring activities. Specifically, the sampling and handling of contaminated groundwater from within groundwater contamination plumes beneath the facility creates risk. Natural attenuation lowers this risk by reducing concentrations of constituents-of-concern (COCs) within the contaminant plume, and the control of LFG will further reduce the COCs, and therefore, the risk. The presence of LFG, especially methane, produces some risk. Methane is migrating in the subsurface in the vicinity of the northeast portion of the existing landfill at concentrations above the lower explosive limit (LEL), so there is some risk of explosion where people and/or equipment Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 9 are disturbing the ground surface; therefore, special care should be taken in conducting any such activities within the area of LFG migration. Once the methane migrates out of the soil into the atmosphere, it is very quickly dissipated and does not pose a significant risk. Control of LFG will significantly reduce the risk from migrating methane. 3.1.2 Magnitude of Residual Risks in terms of Likelihood of Further Releases due to Wastes Remaining Following Implementation of a Remedy The cap above the closed MSW landfill is expected to limit percolation of water through the MSW waste, therefore limiting leaching of waste constituents into the groundwater. Once the C&D unit on top of the closed MSW is closed and capped, this will further reduce water infiltration. Natural attenuation appears to be occurring beneath the facility at a rate that will prevent migration of the COCs beyond the property boundary at concentrations exceeding their respective GPS. In addition, control of LFG will reduce the risk associated with any continued release, either from landfill leachate of from LFG. Wastes anticipated to be produced under the current remedies are limited to purge water associated with performing groundwater monitoring events at the facility. The purge water will be discharged to the ground surface and allowed to naturally infiltrate to the water table. Current impacts to the groundwater are believed to be at least partially from LFG. The proposed LFG control mechanism will reduce potential impacts to the groundwater on the northeast side of the landfill. Wastes associated with implementation of the active LFG control remedy will small amounts of soil during trenching to install pipelines from the existing gas vents to the proposed GEU, and installation and connections for the condensate sump. It is not anticipated that any waste will need to be excavated; however, should any waste be encountered, the waste will be taken to the on-site MSW transfer facility for disposal off site. Soil removed during vent installation or trench excavation is not expected to be contaminated, and will be disposed of on site, possibly as daily cover material. No residual risk is anticipated. After installation of the active LFG control is implemented, condensate from the active LFG system will be an additional waste, which will be pumped out and properly disposed off-site by the County as needed. 3.1.3 Type and Degree of Long-term Management Required, including Monitoring, Operation, and Maintenance MNA will not require long-term operation and maintenance activities; however, long-term monitoring of facility compliance wells and performance/sentinel wells will be required. The Corrective Action Monitoring Plan (CAMP) included in the 2008 CAP will continue until no NCSWMR Appendix II constituents have been detected in groundwater above GPS for three consecutive years. The current passive LFG control mechanism is a passive system which requires little or no maintenance. Once the active LFG system is implemented, significantly more operation and maintenance will be needed, as described in Section 2.3.5. The LFG system will be inspected regularly to be sure that the system has not been damaged and is operating as designed. Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 10 3.1.4 Short-term Risks that Might be Posed to the Community, Workers, or the Environment during Implementation of such a Remedy, including Potential Threats to Human Health and the Environment Associated with Excavation, Transportation, and Redisposal or Containment; Short-term risk associated with MNA is limited to environmental professionals and/or County employees participating in MNA groundwater monitoring activities. Specifically, the sampling and handling of contaminated groundwater from monitoring wells constructed within groundwater contamination plumes create risk; however, the potential for human exposure to landfill contaminants by environmental personnel and/or County employees will be low as long as standard health and safety procedures are followed. Short-term risks associated with the implementation of the LFG control mechanism include potential exposure to organic gases, including methane and hydrogen sulfide. The methane could be vented at possibly explosive concentrations. There may also be physical risks associated with trenching and construction of the LFG system. Gas monitoring will be performed during construction activities to insure worker safety. A site-specific health and safety plan (HASP) will be implemented to insure adherence to OHSA safety standards and related regulations during construction and other phases of this project. 3.1.5 Time until Full Protection is Achieved; A schedule for achievement of the final remedial objective (COC levels below the GPS at all points within the plume beyond the point of compliance) is dependent upon independent factors within the uppermost aquifer that were measured during the NES activities. Any prediction of a timeframe for achievement of concentration levels below the GPS at this time would be an estimate based on available data and professional judgment. Groundwater quality will be monitored in accordance with the facility’s CAMP, and will be completed when no NCSWMR Appendix II constituents have been detected in groundwater above GPS for three consecutive years. 3.1.6 Potential for Exposure of Humans and Environmental Receptors to Remaining Wastes, Considering the Potential Threat to Human Health and the Environment Associated with Excavation, Transportation, Redisposal, or Containment; Water quality and LFG monitoring will be performed by environmental personnel trained to minimize their exposure to COCs by using appropriate personal protective equipment and by avoiding contact with contaminated groundwater, vapors, and gas. Wastes associated with implementation of the LFG control mechanism will include soil removed during trench excavation, which is not expected to be contaminated or to contain any solid waste material. It will be disposed of on site, possibly as daily cover material. No exposure potential is anticipated. Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 11 Facility workers do not come in contact with contaminated media during day-to-day landfill operations. The general public is not expected to come in contact with contaminated media since access to the contaminated media is restricted. 3.1.7 Long-term Reliability of the Engineering and Institutional Controls Natural attenuation is a proven remedy for facilities similar to the Johns River Landfill (i.e., a facility with low contaminant concentrations and low risk associated with the delineated contamination). In addition, results from the biodegradation screening suggest that natural attenuation is occurring at a rate that will prevent further off site migration of the delineated contaminant plume, and will begin reducing concentrations of constituents-of-concern to concentrations below their respective GPS. Therefore, MNA is considered a reliable remedy to meet clean-up goals at the facility. The current control mechanism for LFG is a passive system that requires little or no maintenance and will continue to intercept gas migrating from the landfill for several decades. It is considered to have excellent long-term reliability. If the contingency active LFG system is implemented, more maintenance will be required, and mechanical components of the system may need repair or replacement every few years; however, active LFG systems have well-established long-term reliability. 3.1.8 Contingency Plans and Potential need for Replacement of the Remedy. Replacement of MNA and/or the LFG control mechanism as part of the facility remedy will be performed upon determining that they are not preventing migration of constituents-of-concern beyond the property boundaries. This will be determined by monitoring groundwater sampling locations downgradient of the impacted monitoring wells within the plume of contamination in accordance with the facility’s CAMP. In the event that monitoring indicates that natural attenuation is inadequate for controlling the plume, enhanced bioremediation may be implemented to accelerate the rate of attenuation/mitigation, as described in the 2008 CAP. If the proposed active LFG system is demonstrated to be ineffective at controlling LFG migration and reducing LFG impacts to groundwater on the northeast side of the existing landfill, a new contingency action may be implemented. The new contingency may include installation of additional gas vents or a gas intercept trench between the active gas vents and the C&D expansion area, which could them be connected to the active gas extraction system. If LFG is demonstrated to be a significant source of groundwater impacts for other areas of the landfill away from the proposed LFG system, the proposed system may be extended, and/or additional vents may be installed. 3.2 Controlling the Source According to 15A NCAC 13B.1636(c)(2), the County is required to evaluate the effectiveness of the remedy in controlling the source to reduce further releases based on consideration of the following factors. Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 12 3.2.1 The Extent to which Containment Practices will Reduce Further Releases The closed Johns River MSW landfill is unlined; however, it was closed with a low-permeability soil cap, which acts as a base to the active C&D landfill. The low-permeability cap is expected to limit percolation of water through the MSW, therefore limiting leaching of waste constituents into the groundwater. Furthermore, upon closure, the C&D landfill will also be capped with a cap of equal or lower permeability. The installation of an LFG vents will not affect generation of additional LFG by the landfill, but it will prevent it from migrating away from the landfill and it will reduce LFG impacts to groundwater. 3.2.2 The Extent to which Treatment Technologies may be Used MNA and Phytoremediation use natural processes to treat releases of solid waste constituents to the groundwater. The LFG control system will not treat the groundwater directly, but will prevent or lessen future cross-media impacts to the groundwater by LFG. 3.3 Remedy Implementation According to 15A NCAC 13B.1636(c)(3), the County is required to evaluate the ease or difficulty of implementing a potential remedy based on consideration of the following types of factors. 3.3.1 Degree of Difficulty Associated with Constructing the Technology Installation of the proposed active LFG control mechanism will be a relatively easy and routine construction project involving purchase and installation of a turn-key GEU, installation of a condensate sump, and installation of piping to connect the existing passive gas vents to the GEU and to the condensate sump. 3.3.2 Expected Operational Reliability of the Technologies Natural attenuation is considered a reliable remedy for facilities that have contaminant plumes that: 1) have low level concentrations of organic solid waste constituents; 2) are contained within the facility boundary; 3) are stable or shrinking in size; and/or 4) have low levels of risk. The contaminant plume at this facility has all of these characteristics; therefore, MNA is a reliable remedy for reported contamination at the landfill. The proposed control mechanism for LFG is a passive system that will require little or no maintenance and will continue to intercept gas migrating from the landfill for several decades. It is considered to have excellent operational reliability. If the contingency active LFG system is implemented, more maintenance will be required, and mechanical components of the system may need repair or replacement every few years; however, active LFG systems have well-established reliability. Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 13 3.3.3 Need to Coordinate with and Obtain Necessary Approvals and Permits from Other Agencies; None of the proposed remediation activities will require approvals or permits from other agencies at this time. 3.3.4 Availability of Necessary Equipment and Specialists Natural attenuation processes and LFG control are monitored by readily available laboratory and field procedures and equipment. The monitoring may be conducted by any properly-trained environmental field technicians or consultants. Installation of the LFG vents may be accomplished by any licensed driller a bucket rig, or with an auger rig, for vents outside of waste. If the contingency active LFG system is implemented, there are several venders who build turn-key GEUs that will be acceptable for this application, and any construction contracting firm experienced in trenching and pipe installation will be able to do the installation work. 3.3.5 Available Capacity and Location of Needed Treatment, Storage, and Disposal Services No treatment, storage, or disposal services are required to implement the proposed corrective actions. 3.4 Owner/Operator Capability According to 15A NCAC 13B.1636(c)(2), the County is required to evaluate the practicable capability of the owner or operator, including a consideration of the technical and economic capability of the owner/operator, to construct and/or maintain the proposed remedy. The County anticipates continuing its use of a qualified environmental consulting firm to perform and/or coordinate implementation of the proposed corrective actions and monitoring and reporting activities associated with the landfill. In addition, the County has budgeted for additional monitoring requirements associated with this remedy; therefore, the County is capable of performing the proposed remedy. The financial assurance mechanism for this work will be or has been submitted under separate cover. 3.5 Community Concerns According to 15A NCAC 13B.1636(c)(5), the County is required to evaluate the degree to which community concerns raised as the result of the public meeting are addressed by the potential remedy. In accordance with 15A NCAC 13B.1635(4)(d), Burke County held a public meeting on May 16, 2006 to discuss the results of the ACM. The proposed remedies, including control of LFG, were discussed in the public meeting. The County did not receive any comments during the required public meeting and public comment period; therefore, there were no community concerns to address. Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 14 4.0 WATER QUALITY MONITORING PLAN Groundwater was formerly monitored in accordance with the September 1996 Water Quality Monitoring Plan (WQMP), and the Corrective Action Monitoring Plan (CAMP) included in the 2008 CAP. In August 2012, the County submitted a new WQMP as part of the Permit to Construct Application for the C&D expansion. The 2012 WQMP covers both the existing landfill and the proposed C&D expansion and replaced the previous WQMP and CAMP. In the 2012 WQMP, piezometer PZ-38 was designated to be converted to a compliance monitoring well to monitor Phase 1 of the C&D expansion after it was constructed. The 2013 CAP Addendum added provisions to monitor and evaluate the effectiveness of the proposed control of LFG remedy. Under the 2013 CAP addendum, piezometers PZ-36 and PZ-38 were converted to permanent monitoring wells MW-36 and MW-38 to act as performance wells for the control of LFG remedy for the northeastern part of the existing landfill. MW-38 now plays a duel role as a compliance well and a performance well. MW-36 and MW-38 are located between the existing landfill and Phase 1 of the C&D Expansion, within the zone of methane migration. Groundwater from these two piezometers show GPS exceedances believed to be due to LFG impacts. After installation of the passive LFG vents, MW-36 and MW-38 have been sampled semiannually in conjunction with the routine semiannual water quality sampling, for the COC list, plus dissolved methane and dissolved carbon dioxide. It was expected that the gas vents would decrease the LFG impacts to groundwater beneath the northeastern portion of the landfill, and with time, the concentrations of VOCs and dissolved gases in MW-36 and MW-38 will decrease. Such a decrease was to be considered evidence of the effectiveness of the passive vents at remediating the groundwater impacts. If after an extended period of monitoring, no significant decrease in concentrations of COCs was observed in MW-36 and MW-38, recommendations were to be made to implement the contingency active LFG remedy. Figure 2 presents a series of charts showing the concentrations of the constituents of concern in MW-36 and MW-38 vs. time from February 2013 through December 2016. The charts show decreasing trends in the concentrations of the COCs since the installation of the gas vents in November 2013. This constitutes evidence that the remedy is reducing the concentrations of COCs in MW-36 and MW-38; therefore, the remedy is working effectively as designed. However, in a letter dated March 27, 2017, the NCDEQ-SWS requested implementation of the County’s corrective action contingency plans, and asked that the proposed alternate remedy be implemented. After implementation of the active gas extraction alternate remedy, the GWMP will remain the same. MW-36 and MW-38 will continue to be monitored as performance wells for the control of landfill gas remedy. Continued decreases in the concentrations of VOCs and dissolved gases in MW-36 and MW-38 will be considered evidence of the effectiveness of the active gas extraction system at remediating the groundwater impacts. Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 15 5.0 EVALUATION OF EFFECTIVENESS AND REPORT SUBMITTALS 5.1 Physical and Chemical Changes in Aquifer Conditions Data obtained from the semiannual sampling events, including groundwater elevation and flow, groundwater field and indicator parameters, and constituent concentrations will be evaluated with regard to the physical and chemical conditions in the uppermost aquifer at the site. Any significant changes in the conditions in the aquifer will be reported with recommendations on corrective actions, changes in the monitoring program, or other appropriate responses. 5.2 Physical and Chemical Changes in Plume Characteristics Data obtained from semiannual water quality sampling will be used to re-evaluate the risk posed by the residual plume in accordance with the CAMP included in the 2008 CAP. If COC concentrations are observed to be less than the established GPS in sentinel wells, no action will be required, and the routine compliance and corrective action monitoring will continue until the remedial objective is achieved and the Corrective Action Program is suspended. Performance wells MW-36 and MW-38 will be sampled semiannually in conjunction with the routine semiannual water quality sampling for the COC list, plus dissolved methane and dissolved carbon dioxide. Observed decreases in VOC concentrations and/or decreases in dissolved methane and carbon dioxide will constitute evidence that the control of LFG remedy is effectively controlling gas migration and reducing gas impacts to groundwater. Increases in concentrations of VOCs or methane and carbon dioxide will be considered evidence that the remedy is not effective. 5.3 Refining the Site Conceptual Model Any new information that comes to the attention of the facility, either from the data collected on site or other sources, which impacts the site conceptual model will be reported and evaluated. This includes data on site or regional geology, hydrogeology, or other aspects of the site conceptual model. The site conceptual model will be refined in response to the new information as needed and appropriate. 5.4 Evaluation of Remedy Effectiveness The MNA plus phytoremediation remedy will be evaluated based on analytical results obtained from the performance wells MW-11, MW-12, MW-16S, and MW-17, and sentinel wells MW-18 and MW-19, in accordance with the CAMP. Data obtained from these wells will be tracked using moving average concentration trend graphs to evaluate the effectiveness of the MNA remedy. The concentration trend graphs will provide a visual means for evaluating the effectiveness of the MNA plus phytoremediation remedy. In addition, evaluation of MNA indicator parameters will be used to evaluate the natural attenuation process. Evaluation of the control of LFG remedy will be based primarily on semiannual sampling of MW-36 and MW-38 as performance wells. Observed decreases in VOC concentrations and/or Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 16 decreases in dissolved methane and carbon dioxide in PZ-36 and PZ-38 will constitute evidence that the control of LFG remedy is effectively controlling gas migration and reducing gas impacts to groundwater. Increases in concentrations of VOCs or methane and carbon dioxide will be considered evidence that the control of LFG remedy is not effective. In addition, methane, carbon dioxide, and oxygen concentrations will be monitored at the existing permanent and temporary gas probes in the vicinity of the passive gas vent system. This will include GP-2S, GP-2M, & GP-2D, TGP-1, TGP-2, TGP-3, TGP-4, TGP-6, TGP-7, and TGP-9. These probes will be monitored prior to installation of the passive gas vents, approximately one month after installation of the gas vents, and quarterly after that. The temporary gas vents will be monitored quarterly until they need to be abandoned for construction of the C&D landfill expansion, or until the NCDEQ agrees that they no longer need to be monitored. The LFG monitoring data will be used to supplement the groundwater data in evaluation of the effectiveness of the passive vent remedy. The data from the two performance wells (MW-36 and MW-38) will be evaluated to determine the effectiveness of the passive vent system in the CAER for the preceding CAER period. If the CAER concludes that the control of LFG remedy is not effectively controlling gas migration and reducing gas impacts to groundwater, the CAER may recommend modifications to the existing remedy to improve its effectiveness. For example, the CAER may recommend hooking gas vents GV-8 through GV-11 to the active system, or it may recommend installation of additional vents or gas intercept trenches. If necessary, the CAER may recommend that new or additional remedies be evaluated, and if appropriate, implemented. 5.5 Corrective Action Program Reporting The routine compliance monitoring for this site shall continue to be reported semiannually in accordance with NCSWMR §1634 (Assessment Monitoring Program) and the WQMP and CAMP for the facility. The additional data gathered for the performance wells and sentinel will be included in the semiannual Water Quality Monitoring Reports (WQMRs). In addition to the semiannual WQMRs, the performance criteria for the groundwater corrective action remedies will be evaluated and presented to the NCDEQ every five years in a Corrective Action Evaluation Report (CAER). The first CAER for the facility was submitted to NCDEQ in May 2011 and covered the MNA and phytoremediation remedies. The second CAER for the facility was submitted to NCDEQ in April 2016 and covered the MNA and phytoremediation remedies as well as the passive control of LFG remedy. The April 2016 CAER was approved by the NCDEQ in a letter dated April 19, 2016. The next CAER is due after the second semiannual sampling event of 2020 and will also include evaluation of the active control of LFG remedy. The CAER may provide recommended modifications to the CAP, recommendations to initiate alternative remedies, recommendations to suspend CAP monitoring, or other actions, as appropriate. The CAER shall include, at a minimum, a summary report, data tables, laboratory reports (if not previously submitted), groundwater elevation contour maps, isoconcentration contour maps, cross sections showing groundwater elevations and isoconcentration contours, an Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 17 evaluation of the effectiveness of the corrective action, and graphs illustrating trends of key indicator parameters and/or constituents from key/representative monitoring stations. In the event that a GPS exceedance is confirmed in one or more sentinel well samples based on routine MNA monitoring results pursuant to the CAP, Burke County will notify NCDEQ in writing of: (1) the confirmed exceedance; and (2) the County’s intended course of action to address the GPS exceedance. After the remedial objectives of the CAP have been obtained for the required time period, Burke County will notify the NCDEQ of its intent to suspend the monitoring requirements of the CAP and of its intent to revert to Assessment or Detection Monitoring, as appropriate, in accordance with the NCSWRM and the facility’s WQMP. 6.0 SCHEDULE AND MAINTENANCE 6.1 Schedule Considerations According to 15A NCAC 13B.1636(d), the owner/operator is required to specify, as part of the selected remedy, a schedule for initiating and completing remedial activities. Such a schedule shall require the initiation of remedial activities within a reasonable period of time, taking into consideration the factors set forth in §.1637(d). 6.2 Timeline 6.2.1 Monitoring Schedule Upon considering the factors set forth in §.1637(d), and based on the results of the natural attenuation scoring results, natural attenuation is occurring at a rate that will prevent the migration of solid waste constituents beyond the landfill property boundary at concentrations exceeding the GPS. This portion of the proposed remedy is already in place at the landfill. Monitoring and reporting will proceed semiannually in accordance with the CAP and the CAMP. Similarly, monitoring for the passive control of LFG remedy has been ongoing in accordance with the 2013 CAP Addendum, and this revised addendum does not add any additional monitoring requirements. 6.2.2 Active GEU Implementation Schedule The following timeline is proposed for implementation of the active control of LFG remedy: Activity Schedule Prepare construction plans and bid documents for purchase and installation of the active GEU system. Within 60 days of approval of the CAP Addendum by the NCDEQ Obtain approval of Burke County Board of Commissioners to go to bid Within 120 days of approval of the CAP Addendum by the NCDEQ Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 18 Obtain bids for purchase and installation of the gas extraction system Within 45 days of Board approval Select contractor, negotiate contract, and get Board of Commissioners' approval of the contract Within 45 days of obtaining bids Begin construction/installation of the system Within 60 days of Board Approval Complete construction/installation of the system and bring online Within 45 days of beginning Construction Prepare Gas Extraction System Construction Report with construction drawings and specifications and submit to NCDEQ Within 30 days of completing Construction 6.3 Operations and Maintenance (O&M) The facility shall establish a site-specific, routine inspection schedule, the frequency of which shall be appropriate for the maintenance requirements of the monitoring network and the LFG control system. Inspection results shall be recorded and placed in the facility’s Operating Record. 6.4 Safeguards and Safety The facility shall establish a site-specific health and safety guidelines for the monitoring system and monitoring activities, including installation of gas vents, sampling of monitoring wells, and monitoring of LFG. The guidelines shall include appropriate security for the monitoring wells and vents, such as locked protective casings and/or access restrictions, as well as descriptions of appropriate personal protective equipment for routine and anticipated activities. 6.5 Modification of Corrective Action or Schedule Any requests for modifications of the approved corrective action and/or the implementation schedule must be submitted in writing to the Solid Waste Section, and the requested modifications may not be implemented until approved in writing by the Division of Waste Management. 7.0 FINANCIAL ASSURANCE Burke County’s financial assurance information has or will be submitted under separate cover. 8.0 COMPLETION OF CORRECTIVE ACTION Once concentrations of the constituents of concern are below established GPS at and beyond the relevant point of compliance as defined in 15A NCAC 13B.1631(a)(2) for three consecutive years, the corrective action will be considered complete. If the facility is in the post-closure care period at the end of the Corrective Action Program, Assessment Monitoring will be continued. After the Addendum to Corrective Action Plan Joyce Engineering Johns River Waste Management Facility, Permit 12-03 August 2013, Rev. January 2018 19 remedial objectives of the CAP have been obtained for the required time period, Burke County will notify the DEQ of its intent to suspend the monitoring requirements of the CAP and of its intent to revert to Assessment or Detection Monitoring, as appropriate, as defined in the facility’s Transition Plan and WQMP. In accordance with 15A NCAC 13B.1637(f), a certification that corrective action has been completed in compliance with the requirements of 15A NCAC 13B.1637(e) will be submitted to NCDEQ. 9.0 REFERENCES The references cited below were used to prepare this document and may or may not be cited in the text of this report.
