NPDES Permit NC0005088
Chemical Amendment Request to Permit Renewal Application
Dear Dr. Chernikov:
Duke Energy Carolinas,LLC submits this letter to amend our existing NPDES Wastewater permit
application. The amendment is to disclose the use of Hydrex 60240 (Aluminum Chloride
Hydroxide Sulfate) for use in the wastewater treatment system. This product will be used to aid in
TSS control. An updated list of chemicals is attached, as well as the Hydrex 60240 SDS. Please
include this with the relevant permit files.
It is our understanding that with this amendment to the existing permit application, no permit
modification would be necessary, and Duke Energy is authorized to utilize the additives to assure
compliance with NPDES permit limits.
If you have any questions, please contact Mr. Randy Hawkins at (864) 356-8257 or
[e-mail].
"I certify, under penalty of law, that this document and all attachments were prepared under my direction
