Subject: Compliance Evaluation Inspection
Gastonia — Two Rivers WTP
NPDES Permit No. NCO040070
Gaston County
Dear Mr. Peoples:
Enclosed is a copy of the Compliance Evaluation Inspection for the inspection conducted
at the subject facility on February 21, 2018, by Mana Schutte and On Tuvia. Christopher High's
cooperation during the site visit was much appreciated. Please advise the staff involved with this
NPDES Permit by forwarding a copy of the enclosed report.
The main area of concern discovered at the time of the inspection was that the facility
chlorine sampling method is inadequate due to the fact it can only detect chlorine level under 50
ug/L, while the permit limit is 17ug/L.
The report should be self-explanatory; however, should you have any questions
concerning this report, please do not hesitate to contact Ori Tuvia at [phone], or at
ori.tuviat�D ncdenngov .
Sincerely,
1�
