NPDES General Permit NC500000 Notice of Intent Renewal Application
Dear Mr. Weaver:
By this correspondence, Progress Energy respectfully requests continued coverage under the National
Pollution Discharge Elimination System (NPDES) General Permit NCG500000 for the referenced
hydroelectric facilities. Enclosed are three copies of the completed Notice of Intent renewal application
form with supporting documentation for each facility. The reported volume of discharge for each
discharge point represents the average instantaneous flow during sampling. Sampling is conducted only
during flow events and flow only occurs during plant operation.
Please note that these Notices of Intent do not require a separate application fee as indicated on the
checklist. Each permitted facility pays the annual fee for continued coverage under this NPDES General
Permit. Also note that because none of these facilities are new nor are expanding with this application, no
alternatives analyses are required.
If there are any questions regarding our requests or the enclosed application information, please contact
Ms. Robin Bryson at [phone] or email at [e-mail].
I 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
qualified 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. I am aware that there are significant
penalties for submitting false information, including the possibility of fines and
imprisonment for knowing violations.
