RE: Permit Waiver Request
Groundwater Assessment
Mayo Steam Electric Plant Landfill Person County Solid Waste Permit Number 7305-INDUS

Dear Ms. Werner: On January 31, 2017, Duke Energy submitted a Work Plan for groundwater assessment at the
Mayo Steam Electric Plant (Solid Waste permit #7305-INDUS).

The Landfill permit was issued by the Department of Environmental Quality (DEQ) Solid Waste Section on July 10, 2014. Attachment 3, Part IV, #15, states: “A licensed geologist must be present to supervise the installation of groundwater monitoring wells.” With this letter, Duke
Energy requests, for the groundwater assessment, a waiver from the aforementioned requirement.
A Professional Geologist (P.G.) familiar with the geology and layout of the facility, and
approved Water Quality Monitoring Plan, will be on call throughout drilling. A field technician, under the supervision of the P.G., will be present throughout drilling.
Additionally, Attachment 3, Part IV, #21, states: “All well construction records and soil boring
logs for new wells must be submitted to the Solid Waste Section Hydrogeologist for review
within 30 days of completion". Construction records and boring logs require quality assurance prior to distribution with data gathering and verification extending beyond 30 days from individual well installation. Duke proposes that construction records and boring logs for the
aforementioned assessment be submitted to the Solid Waste Section Hydrogeologist in the final
assessment report as one project.
This request is being submitted for incorporation into the pending Work Plan approval.
