Subject: Leachate Tank and Secondary Containment Plan Proposed Dan River Landfill Duke Energy – Dan River Steam Station Eden, North Carolina Amec Foster Wheeler Project No. 7810140065 Dear Ms. Witt: Amec Foster Wheeler is pleased to provide this Leachate Tank and Secondary Containment Plan to Duke Energy (Duke) for the proposed Dan River Landfill at Duke’s Dan River Steam Station. Amec Foster Wheeler is also attaching the Dan River Steam Station legal property description which was prepared for Duke by ESP Associates, P.A. We understand that Duke will provide these documents to the North Carolina Department of Environmental Quality (NCDEQ) Solid Waste Section (SWS). The Leachate Tank and Secondary Containment Plan drawings included with this submittal address the design of the leachate storage tank, secondary containment facility, leachate force main piping, and tie-in into the City of Eden sanitary sewer system. Development of a leachate discharge agreement between Duke and the City of Eden is in progress. Additional information regarding the proposed leachate tank and secondary containment is provided as follows. Leachate Tank The proposed leachate tank will consist of a ModuTank MS110-17 modular-style galvanized steel uncovered tank, or equivalent as approved by the Engineer. Containment will be provided by a geomembrane within the tank. The geomembrane will be anchored at the top of the tank and ballasted at the bottom of the tank; therefore, there is no minimum required depth of water needed to maintain the tank. The tank will have a capacity of 1,000,000 gallons at the service elevation, with an additional two feet of freeboard in accordance with North Carolina solid waste rules for uncovered storage tanks at municipal landfills generally referred to as the .1600 rules. Leachate Tank and Secondary Containment Plan Dan River Landfill Duke Energy – Dan River Steam Station Eden, North Carolina Amec Foster Wheeler Project No. 7810140065 May 17, 2016 2 Modular Tank Anticipated Service A typical landfill is designed, permitted, and constructed to serve as a facility to contain a consistently generated waste stream; therefore, a typical landfill may have an active lifespan on the order of several decades. The proposed Dan River Landfill modular tank is anticipated to have a relatively short service life on the order of ten years due to the following factors:  The Dan River Landfill will not accept waste materials from other steam stations or other off-site sources.  The Dan River Landfill will contain waste materials due to closure of the existing inactive on-site coal combustion residual (CCR) units.  The Dan River Station no longer produces energy by burning coal; therefore, the waste stream is of a finite quantity and no new CCR waste is being generated.  North Carolina’s Coal Ash Management Act (CAMA) requires closure and remediation of the Dan River Station CCR surface impoundments by August 1, 2019.  The Dan River Landfill will be closed upon closure and remediation of on-site CCR units.  Leachate generation is anticipated to decrease following closure of the Dan River Landfill as shown in the “Leachate Generation Calculation” provided in the “Engineering and Facility Plan – Dan River Landfill”, Amec Foster Wheeler, December 24, 2015.  The proposed modular storage tank will be replaced by a smaller storage device with secondary containment upon a demonstration of a sustained decrease in leachate generation and approval by the NCDEQ-SWS. The proposed modular storage tank will be disassembled upon incorporation of the smaller storage device. Modular Tank Liner The proposed ModuTank MS110-17 modular tank will incorporate a 45-mil reinforced polypropylene geomembrane liner, or as proposed by the tank Manufacturer and approved by the Engineer. As previously discussed, the modular tank and tank liner is anticipated to be in service on the order of ten years. During service, the proposed geomembrane tank liner will be inspected, repaired, and replaced in accordance with the Manufacturer’s recommendations. Modular Tank Performance History ModuTank Inc. has been manufacturing above-ground modular storage tanks since 1970 for a variety of applications, and has sold more than 30 modular storage tanks in North Carolina since 1987. Modular storage tanks have been successfully used at the following municipal solid waste (MSW) landfill facilities:  CSS Landfill, Republic Services, Avalon, TX, installed December 2010.  Arlington Landfill, Republic Services, Evless, TX, installed December 2010.  Galveston Landfill, Republic Services, Santa Fe, TX, installed March 2012.  Ellis County Landfill, Republic Services, Ennis, TX, installed May 2013.  Itaska Landfill, Republic Services, Taska, TX, installed May 2013.  McCarty Road Landfill, Republic Services, Houston, TX, installed September 2014. Leachate Tank and Secondary Containment Plan Dan River Landfill Duke Energy – Dan River Steam Station Eden, North Carolina Amec Foster Wheeler Project No. 7810140065 May 17, 2016 3 Secondary Containment A soil berm will provide storage capacity for the leachate tank secondary containment area. The secondary containment area storage volume was designed to be in excess of 1,100,000 gallons, or 110 percent of the leachate tank storage volume as required by the .1600 rules. Containment will be provided by a 60-mil high density polyethylene (HDPE) geomembrane with an anchor trench at the top of the soil berm. The geomembrane will be overlain by an 8 oz/sy non- woven geotextile and at least 12 inches of aggregate to protect the geomembrane. The secondary containment area will be graded to drain to a sump in the southern portion of the containment area. Liquids collected in the sump will either drain to the landfill perimeter channel by gravity via an HDPE pipe if leachate is not present or will be pumped back to the storage tank if leachate is present. Gravity flow through the HDPE pipe will be controlled by a butterfly valve which will be maintained in the closed condition until it can be determined via visual observation that leachate is not present in liquids collected in the secondary containment area sump. Force Main The proposed leachate force main will be located on Duke property and will consist of approximately 2,269 linear feet of dual-contained solid-walled HDPE pipe. The force main will begin at the pump pad on the northeast side of the secondary containment facility. Approximate Stations 0+00 to 2+00 will be located along the outside edge of the proposed landfill perimeter access road. Approximate Stations 2+00 to 5+00 will be located through a wooded area west of the proposed Dan River Landfill. Approximate Stations 5+00 to 20+00 will be located along an existing dirt road near the northern boundary of the Dan River Station property. The proposed leachate force main will cross Edgewood Road between approximate stations 20+00 to 20+50. The force main will cross Edgewood Road on Duke property beyond the limits of the North Carolina Department of Transportation (NCDOT) right-of-way (ROW). Approximate Stations 20+50 to 22+69 will be located along the western side of Edgewood Road on Duke property outside of the NCDOT ROW. The proposed tie-in to the City of Eden sanitary sewer system will be at approximate station 22+69. The force main will include at least one air release valve at a high point along the alignment and one witness manhole at a low point along the alignment. Tie-In to City of Eden Sanitary Sewer System The proposed leachate force main will tie in to the City of Eden sanitary sewer system on Duke property near an existing air release valve on the west side of Edgewood Road approximately 375 feet north of the gated entrance to the Dan River Station. A check valve, gate valve, and flanged outlet tapping sleeve will be utilized at the tie-in between the proposed leachate pipe and the existing City of Eden sanitary sewer force main. The location and configuration of the tie-in was discussed with the City of Eden and their consultants. A manhole will facilitate access, inspection, and maintenance of the tie-in.
