Subject: AnodamineTM Use at NC Facilities
NPDES Permit application amendment
Dear Mr. Belnick:
RECEIVED/NCDEQ/DWR

Writer Quality
Pertnitting Section
Duke Energy Carolinas, LLC and Duke Energy Progress, LLC (collectively, "Duke Energy") are
seeking your concurrence in the use of AnodamineTM for equipment maintenance at the stations
listed below, under existing NPDES permits. The use of AnodamineTM is not anticipated to be a
material or substantial alteration or addition that requires a permit modification under 40 C.F.R.
122.62 or a change in condition that requires a limitation of the permitted discharge under 15A
N.C.A.C. 021-1.0114.
Duke Energy routinely uses water chemistry products for the maintenance of equipment
components at our generation sites. Facilities require scheduled maintenance at routine
intervals (outages). During outage maintenance activities or extended periods where units are
not in demand, boilers are placed in a layup mode. In order to protect the internal metal
surfaces, AnodamineTM will be introduced to establish a protective coating or barrier, which in
turn reduces corrosion during startup. While most of the AnodamineTM will be consumed in the
process, there may be trace amounts remaining in the boiler and associated blowdown water as
the boiler unit starts up and comes online. The Safety Data Sheet for AnodamineTM is attached.
Note that Section 12 - Ecological Information, indicates that the LC50 for the most sensitive
organism tested (Pimephales) is 49,210 mg/I. At Duke Energy plants, AnodamineTM will be
introduced into the boiler chemistry cycle at an initial concentration of 1.0 mg/l, and the
concentrations in effluent (if any) will be lower. Thus, to the extent AnodamineTM is found in
effluent, it is not expected to have any impact on receiving waters.
Duke Energy further requests that the Division accept this letter as a modification to all pending
NPDES permit applications; specifically, we request that AnodamineTM be added to our EPA
Form 3510-2C Section VI: "Potential Discharges not covered by Analysis". Future NPDES
renewal applications will explicitly include this maintenance product, if its use is still anticipated.
This communication covers use at the following stations:
