Subject: Confirmation of Excavation Requirements for the L.V. Sutton Energy Complex — 1984 Basin
Dear Mr. Draovitch:
The purpose of this letter is to confirm excavation requirements are being met in the L.V. Sutton Energy
Complex 1984 Basin based on progress to date. On August 27, 2019, the North Carolina Department of
Environmental Quality (DEQ) received the L. V. Sutton Energy Complex 1984 Ash Basin Documentation for
Closure — Visual Removal of Ash, which includes the 1984 Basin Closure Certification L. V. Sutton Energy
Complex Wilmington, North Carolina by Geosyntec Consultants dated August 16, 2019. The DEQ has
reviewed documentation provided by Duke Energy to assess completion of closure requirements at that portion
of the subject basin. DEQ concurs that the visual confirmation data provided meets the overall objectives of
sample collection and analysis consistent with recommended technical direction outlined in DEQ's Coal
Combustion Residuals (CCR) Surface Impoundment Closure Guidelines for Protection of Groundwater. Soil
analytical results shall be incorporated into the geochemical and transport models that will be included in the
upcoming Corrective Action Plan for the facility.
