Dear Mr. Tankard:
In reference to the Notices of Deficiency and Violation dated February 9, 2021, and received by CWS on February
24th, we offer the following response:
The facility experienced an upset on June 2, 2020 in which three of the five membranes were blinded and flow rates
exceeded the capability of the remaining two. The cause of the upset is believed to be a combination of excessive
discharges of cleaning products from resort properties ahead of a late tourist season start associated with COVID
delays along with floor stripping chemicals from a local shopping center. Operations has contacted those involved in
the discharge to make them aware of alternative disposal methods.
Staff immediately began remedial cleaning of the membranes and diverted flow to upset, but it took several months
to completely remove the foreign substance and recover the treatment process.
If further information or clarification is needed, please contact me or Dana Hill, Operations Director, at 252-269-
2540.
Respectfully,
Brent Milliron
Regulatory Compliance Manager
