NPDES Permit NC0005088
Chemical Amendment Request to Permit Renewal Application
Dear Dr. Chemikov:
Duke Energy Carolinas, LLC submits this letter to amend our existing NPDES Wastewater
permit application. The amendment is to disclose the use of Hydrex 2252 (Amide Hydrolysate)
and Hydrex 2280 TA (Sulfonated acrylate polymer) for use in the Cooling Towers. Hydrex 2252
is a bio-dispersant which prevents organic deposits and fouling. Hydrex 2280 TA is a particle
dispersant to keep solids suspended to prevent fouling of the heat exchangers. Cooling Tower
Blowdown is processed through the site's Wastewater Treatment System before discharge
through Outfall 005. An updated list of chemicals is attached, as well as the Hydrex 2252 and
Hydrex 2280 TA 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 [phone] or
randv.hawk in s(&.du ke-e nerev.com.
V certify, under penalty of law, that this document and all attachments were prepared under my direction
or supervision in accordance with a system designed to assure that qualif ed personnel properly gather and
evaluate the information submitted. Based on my inquiry of the person or persons who manage the system,
or those persons directly responsible for gathering the information, the information submitted is, to the best
of my knowledge and belief, true, accurate, and complete. / am aware that there are significant penalties
for submitting false information, including the possibility of fines and imprisonment for knowing
violations. "
