Subject: Gypsum Pad Assessment Work Plan Comments — Allen Steam Station
Dear Mr. Draovitch:
On June 12, 2019, the North Carolina Department of Environmental Quality Division of Water
Resources (Division) received the proposed Gypsum Pad Assessment Work Plan for the Allen Steam
Station. The Division has reviewed and hereby approves the proposed assessment activities under the
condition that the following items are addressed as part of the plan implementation and the results
reported in the comprehensive site assessment concerning the subject area.
• Please provide a map showing the extent of any liners or concrete pads beneath the gypsum
pad.
If applicable, the results should also be incorporated into the updated CAP's revised geochemical and
groundwater fate and transport models. If the results of the modeling show current or future impacts
to groundwater and/or surface water from this area, then appropriate remedial strategies shall be
proposed in the CAP.
If you have any questions, please contact Brandy Costner (Mooresville Regional Office) at (704) 235-
2185 or Steve Lanter (Central Office) at [phone].
