the post closure operation and maintenance of a SDU located at the DAK Americas, LLC (DAK Americas) Cape Fear Facility (CFF) in Leland, NC (Figure 1). Since its construction in 1973, the SDU has received stabilized Class B Waste Activated Sludge (WAS) generated by the CFF wastewater treatment plant (WWTP). Production operations at the CFF stopped in December 2013. The SDU has been covered in accordance with the Surface Disposal Unit Closure Plan, DAK Americas LLC Cape Fear Facility (OBG, 201S). The SDU is permitted under the Department of Water Resources, permit number WQ0018087. 1.1 SDU DESCRIPTION The SDU encompasses approximately 12-acres, and consists of a former land application sprayfield that has been bermed and covered to contain solids derived from historical waste water treatment at the CFF (Figure 2). The SDU stopped receiving solids and was covered on August 10, 2015, in accordance with the Surface Disposal Unit Closure Plan, DAKAmericas LLC Cape Fear Facility (OBG, 2015). At the time this Plan was prepared, the underdrain and leachate collection system was continuing to produce a small volume of leachate. Leachate generation has been dropping steadily since the cover was completed, and is anticipated to stop soon. Once leachate generation has stopped, the underdrain system will be capped, in accordance with the Surface Disposal Unit Closure Plan, DAKAmericas LLC Cape Fear Facility (OBG, 2015). The cover system consists of four layers, where each layer provides a distinct function. The four layers and their corresponding functions are listed below, in order from the bottom up: 1) Surface Reinforcement Layer 2) Floating Modular Layer 3) Gas Venting System The gas venting system will vent biogas generated to the air outside the impermeable geomembrane. 4) Impermeable Geomembrane Layer The impermeable layer will prevent infiltration of precipitation and promote runoff of stormwater. The following subsections provide details for each layer of the cover system and discuss how they function. 1.1.1 Surface Reinforcement Layer The purpose of the surface reinforcement layer is to stabilize the SDU surface to facilitate installation of the other three layers of the cover system. The surface reinforcement layer consists of a single layer of biaxial geogrid that covers the entire SDU surface. The biaxial geogrid is a polypropylene mesh with a minimum rib thickness of 1,78 mm and normal aperture (mesh opening) dimension of 25 mm. The biaxial geogrid was placed directly on top of the SDU and anchored into the existing berm. The biaxial geogrid functions to distribute loads over a larger area of the SDU. 1.1.2 Floating Modular Layer The purpose of the floating modular layer is to keep the gas venting system and impermeable geomembrane layer above the SDU surface. The floating modular layer consists of thick panels of insulation individually encapsulated in watertight casings of geomembrane. These modular floats have been arranged in a contiguous grid to cover the entire surface of the SDU. Adjacent modular floats were fastened together by thermally welding a strip of geomembrane between each casing. Floats have also been fastened to cables that secure the floats to the berm. The cables span the entire SDU and are anchored into the berm via the anchor trench. Floats are fastened to the cables with a loop of geomembrane thermally welded to each casing. The boundary between casings has not been sealed so that biogas can travel readily to the biogas collection system. OBG 1 11/4/2015 FINAL I 1 r1J I;\6ak-Americas.14974\51437.Cape-Fear-Deeon\Dots\Reports\0 & M Plan\SDUO M Plan Text 11-4-15.docx 1.1.3 Biogas Venting System Anaerobic decay of the SDU contents and production of biogas is anticipated to continue after installation of the cover system. Biogas is a mixture of methane, carbon dioxide and trace gases such as hydrogen sulfide. The biogas venting system consists of a network of gas collection pipes that passively vent to the atmosphere outside the cover. The network of collection pipes is horizontally sandwiched between the floating modular layer and the impermeable geomembrane layer. 1.1.4 Impermeable Geomembrane Layer The impermeable geomembrane layer consists of high density polyethylene (HDPE) with a nominal thickness of 80-mil (0.08-inch). This layer will be assembled by welding sections of HDPE sheets together, near their edges, to create a single continuous sheet to cover the entire SDU surface. Weighted channels will facilitate the collection and routing of stormwater off of the cover. The perimeter of the impermeable geomembrane layer will be anchored into the existing berm. 1.2 STORMWATER CONTROLS AND CONVEYANCES Several stormwater controls and conveyances have been installed to route stormwater off of the SDU cover. These consist of the following: m channels formed in the SDU cover r channels along the outside of the berm lined with grass and permanent reinforcement matting. Stormwater discharged from the surface of the SDU is discharged in accordance with the requirements of NPDES permit NCS000392, for as long as this permit remains active and this permit is in effect. 1.3 FENCING Once work is completed, a security will encompass the entire SDU. The security fence restricts public and wildlife access, as required by 15A NCAC 02T .1109(c)(2)(G) and (H). The closed SDU will be accessible for maintenance through one locked gate. Signs will be posted at the access gate that warn of hazards within the security fence. Signs will warn of the following hazards: ++ Engulfment Drowning Combustible Atmosphere Snakes. 1.4 OBJECTIVES The purpose of this Plan is to establish a process for post -closure care of the SDU and its related components that is: ■ Protective of human health and the environment ■ Specifically compliant with the requirements of the North Carolina Permit for the Surface Disposal of Residual Solids WQ0018087 (SDU Permit), as well as the North Carolina (15A NCAC 02T.1109) and Federal (40 CFR Part 503 Subpart C) regulations pertaining to Surface Disposal of Sewage Sludge r In accordance with the Guidelinesfor the Closure of Permitted Wastewater Ponds and.Lagoons (NCDENR, June 22, 2012) Generally in accordance with the requirements for RCRA Post -Closure Care (40 CFR Part 264 Subpart G).

No routine maintenance is anticipated for the fence surrounding the SDU. 3.1 COVER Cover maintenance will consist of removing debris from the cover and stormwater channels. Maintenance will be performed quarterly. Most debris is anticipated to be wind-blown, such as, pollen, dust and landscaping clippings. Debris shall be removed by leaf blowers, spraying with water and by hand. During maintenance, the cover will be inspected for signs of damage, and repairs will be made, if necessary, as described in Section 5.1. 3.2 BIOGAS VENTILATION SYSTEM Normally, maintenance of the biogas ventilation system will be performed quarterly, concurrently with cover maintenance (Section 3.1). Maintenance will consist of removing debris and vegetation from around gas vents. During maintenance, the biogas ventilation system will be inspected for signs of damage, and repairs will be made, if necessary, as described in Section 5.2. 3.3 BERM Berm maintenance will be performed semiannually, and will consist of mowing to suppress the growth of deep rooted vegetation. During maintenance, the biogas ventilation system will be inspected for signs of damage, and repairs will be made, if necessary, as described in Section 5.3. 3.4 STORMWATER CONVEYANCE SYSTEM The stormwater system will be maintained for as long as the stormwater permit (NPDES permit NCS000392) for the site remains active. Maintenance will consist of following activities, at the prescribed frequency: Landscaping of grass lined channels ■ Clearing of debris and sediment from stormwater features (as needed based on inspection). During maintenance, the stormwater conveyance system will be inspected for signs of damage, and repairs will be made, if necessary, as described in Section 5.4. oBG 1 11/4/15 FINAL 1 5 r0i I:\Dak-Americas.14974\51431.Cape-Fear-Decon\Docs\Reports�0 & M Plan\SDU 0 M Plan Text 11-4.15.docx 4.0 MONITORING Groundwater and methane monitoring will be performed throughout the three-year post -closure period, as described in the sections that follow. 4.1 GROUNDWATER Groundwater monitoring will be performed annually, every December, during the three-year post -closure period, for the parameters specified in the SDU Permit. The monitoring network will include two upgradient and four downgradient monitoring wells (Figure 3). Approximately three years after closure, and with the approval of the DWR, groundwater monitoring will cease and the monitoring wells will be closed and abandoned. The property boundary adjacent the SDU will be monitored quarterly during the post -closure period, to ensure the LEL for methane is not exceeded, as required by 15A NCAC 02T.1109(c)(2)(F). The property boundary is closest to the east side of the SDU; therefore, three points east of the SDU, along the property boundary (Figure 4), will be monitored. Monitoring will be performed with a portable gas meter, capable of measuring LEL, and calibrated with methane gas. LEL will be measured at each monitoring point for a duration of 5 minutes. In the unlikely event that the methane LEL is exceeded at the property boundary, a continuous monitoring device will be installed and LEL will be monitored for 48 hours to provide further information regarding the air quality. If the exceedance is confirmed by the continuous monitoring, measures will be taken to reduce ambient biogas concentrations at the property boundary to below the methane LEL. 08G 1 11/4/15 FINAL 1 6 C\Dak-Americas.14974\51431.Cape-fear-Oecon\Docs\Reports\o & M BE Plan\SOU 0 M Plan Text 11-4-15.docx 5.0 REPAIR Repairs to the various elements of the SDU will be performed on an as -needed basis.
