Steve,
Thanks for sending the MSDS for the flocculant. I understand from our telephone conversation that Duke Energy
received a permit from the USAGE to dredge around the Dan River Plant's intake structure. DWR's General Certification
(GC) #3888 did not require written approval for the project. The work was planned to occur in three phases, and the
first phase is complete. However, Duke Energy can no longer pump the dredge slurry to the coal ash pond for disposal
and is looking at two options for treatment of the return water prior to discharging it to the river or other jurisdictional
surface water. One option is to utilize a Geotube that would require the use of a flocculant. The second option is to
utilize large plastic containers that are capable of holding 500,000 gallons of slurry for settling. You contacted me to
determine if either of these two options would require written approval of GC #3888.
Without reviewing a specific plan, we are uncertain as to whether the Geotube or large plastic container option would
meet Conditions 16 and 17 of the General Certification (GC) for the concentration of settleable solids in the effluent and
turbidity water quality standard.
FLOPAM C -6207 Polymer is not listed as an approved PAM. Please see the attached list of approved PAMs and memo
regarding the use of PAM products. The memo states that only anionic PAMs should be used. FLOPAM C -6207 Polymer
is a cationic PAM, which may violate Condition 9 of the GC for toxic pollutants.
Although not specifically required by the GC if you are able to use an approved PAM with Geotubes or the large plastic
containers without PAM, we recommend submitting a PCN for written approval since you are proposing an alternative
design that is not addressed in the General Certification. Additionally, the discharge water may require an NPDES
permit. Please contact Corey Basinger at (336) 771 -4963 in the Winston -Salem Regional Office for more information
regarding the permitting requirements for discharging to surface waters.
Thanks,
Jennifer

Jennifer,
Attached is the MSDS sheet for the flocculant we propose to use at Dan River. The flocculant will be used to help settle
out solids in a geotube and prevent clogging of the geotube pores.
If this flocculant is not acceptable, we would be open to looking at using another flocculant that has been approved by
DENR, provided that the approved flocculant(s) can meet the project's needs.
Thanks for your help.
