Notice of Violation and Intent to Assess Civil Penalty
Dear Ms. King:
G( JUN 18 2020 f
Aqua North Carolina, Inc. (Aqua) offers the following response to the above referenced Notice of
Violation and Intent to Assess Civil Penalty. This was for violations that occurred in February 2020:
Aaua's Response:
The Beau Rivage wastewater treatment plant effluent does not have a recurring issue or
typically high ammonia concentration. With the fully functional fixed film process, an
elevated ammonia concentration cannot be reasonably explained. There was no known
slug discharge into the facility and no known upset.
The ORC will complete more frequent ammonia process testing and check the process
to determine if this is an emerging problem. July 2018 was the last occasion when we
received an ammonia lab result greater than 10 mg/I at the Beau Rivage W WTF.
If you have any questions or comments, please contact me at [phone].
Sincerely,
/A;7 .
