Box 17177 Chapel Hill, NC 27516-7177 RE: Proposal for Engineering Services DEQ Site-wide Environmental Monitoring Plan Orange County Eubanks Road C&D Landfill, Permit 68-04 & Closed Landfill Units, Permit Number 68-01 Draper Aden Associates Proposal No. R00592-179N-3 Dear Robert: This letter is to serve as our work order request for the subject task. A scope of work and not-to-exceed fee proposal is presented below. Scope of Work At the request of the County, Draper Aden submitted a permit renewal application on June 27, 2017 for the Eubanks Road C&D Landfill Permit and also submitted a revised Operation Plan for the Closed MSW Landfill and associated operations on October 18, 2017. Both of these packages were prepared based upon the previous renewal applications already approved by NCDEQ. Some of the information for the prior permit applications was prepared and developed by DAA while other portions were prepared by other County-hired engineers. DAA’s most recent submissions were made with the most recent information available to DAA along with the desired modifications to the permit documents to reflect changes in existing conditions and operational practices. On January 25, 2019, Mr. Ming-tai Chao issued an email to the County regarding his review of the documents, copy attached. Given the 2018 North Carolina Legislature’s bill that allowed for landfills to apply for a “life of site” permit, Mr. Chao expressed the Solid Waste Section’s desire to have a comprehensive environmental monitoring plan developed as a stand-alone document for the combined facility. A subsequent meeting was held on February 13, 2019 between County, DAA, and State staff to discuss Mr. Chao’s comments and to discern the impacts of what was being requested. This work order request is for the work necessary to address the State’s comments contained in the January 25, 2019 email referred to above and to develop a stand-alone document for the environmental monitoring plan to be followed at the Orange County Landfill complex. The new plan will incorporate available information from the previously approved permit documents and detail the Groundwater Monitoring program at the closed landfill units and for the operational C&D landfill unit; the landfill gas monitoring program used for the open and closed landfill units; the stormwater monitoring plan followed at the facility; and will provide an updated closure and post closure care (CPCC) cost estimate.
