Dear Ms. Ward:

Director
PERCS Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit (IUP)
modification submitted by the City of Eden for the following Significant Industrial User (SIU). The IUP
modification was received by the Division on July 12, 2017.
IUP# SIU
1013 Duke Energy, Dan River Combined Cycle Station
The review indicates, with the observation below, that the IUP is adequate and the minimum
requirements of 15A NCAC 2H .0905 and .0916 and 40 CFR 403.8(f)(1)(iii) are met.
Molybdenum Over Allocation* It is noted that molybdenum is over allocated with the temporary raise of
IUP limit and newly calculated MAHL in the Headworks Analysis This over allocation must be resolved at
the next IUP renewal which is February 28, 2018, unless conditions at the POTW change significantly and
thus warrant an earlier resolution.
Federal and State pretreatment regulations require the local delegated pretreatment program to
effectively control and document the discharge of wastewater from Significant/Categorical Industrial
Users to the POTW It is the POTW's responsibility to ensure that these objectives are consistently met.
Thank you for your continued cooperation with the Pretreatment Program. If you have any questions or
comments, please contact Monti Hassan at [phone] [email- [e-mail]] or
Deborah Gore, Unit Supervisor at [phone] [email: Debora [e-mail]].
