Permit Renewal Application Addendum
Dear Dr. Chernikov:
As noted in the May 31, 2023 NPDES permit renewal application, Outfall 002 operates seasonally (during
warmer weather typically May to October) based on the Evaporative Cooling System (ECS) being placed
into operation. Samples for the permit application were unable to be collected at the time of the May 31,
2023 submittal, since the ECS was not in operation. The ECS went into operation this summer and
samples were collected on July 12, 2023. The results of this sampling event are on the enclosed Form 2C.
Should you have any questions regarding this submittal or require additional information, please contact
Ms. Teresa Williams at [phone] or Mr. Don Safrit at [phone].
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. 1 am aware that there are significant penalties for submitting false
information, including the possibility of fines and imprisonment for knowing violations
Sincerely,
Keith Douthit
Plant General Manager

Check here if you qualify as a small business per the instructions to Form 2C and, therefore, do not need to submit quantitative data for any of the organic toxic pollutants in Sections 2
through 5 of this table. Note, however, that you must still indicate in the appropriate column of this table if you believe any of the pollutants listed are present in your discharge.
