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.
