Subject: Completion of Permanent Alternate Water Supply Requirements Under General
Statute 130A-309.211(cl)
Mayo Steam Electric Plant
Dear Mr. Draovitch:
On August 31, 2018, the North Carolina Department of Environmental Quality (DEQ) received a
request from Duke Energy for Mayo Steam Electric Plant for confirmation of completion of the
permanent alternate water provision under the Coal Ash Management Act (CAMA) General
Statute (G.S.) 13OA-309.211(c1). Based on our review of the submitted documentation, DEQ
hereby confirms that Duke Energy has satisfactorily completed the alternate water provision under
CAMA G. S. 13 OA -3 09.211(c 1) at the Mayo facility.
Please note that, since Duke Energy is still in the process of submitting or finalizing the Corrective
Action Plan for the Mayo Steam Electric Plant and the results of groundwater modeling have not
yet been received, DEQ reserves the right to determine that additional households are eligible and
shall be provided permanent alternate water solutions per G. S. 13 OA -3 09.211(c 1) based on any
new information provided. Any future determination of additional eligible households by DEQ
will not affect this confirmation of Duke's compliance with the October 15, 2018 deadline in G.S.
130A-309.21 l (cl). Further, this confirmation letter does not constitute a final classification for
any impoundment under G.S. 130A -309.213(d).
