Dear Mr. Tharrington,
The Town of Lake Waccamaw is in receipt of your NOV & Intent to Assess Civil Penalty dated November 30,
2020. The NOV is for exceeding the weekly limit of Fecal Coliform at the effluent of our WWTP. We are
requesting that no civil penalty be assessed to the Town. We offer the following comments in support of our
request:
The Town of Lake Waccamaw surpassed its permitted weekly limit for Fecal Coliform during the week of
October 18, 2020 through October 24, 2020. However, the Town was well within its limit for the entire month.
The Town is not sure of what exactly caused the spike in fecal coliform but thinks it may have been caused by
a low level of chlorine in the contact chamber. Total chlorine is checked on testing days at effluent to ensure
wastewater is being treated. On October 20 and 21 the total chlorine test showed chlorine in wastewater. On
October 22, it was found that the chlorine cylinder needed to be changed out. As soon as it was discovered,
the cylinder was changed. The very next time samples were taken at the effluent fecal levels were back to
normal. The Town sends fecal samples to Environment One Inc. and therefore does not know results of
samples for several days. The Town was not aware of the spike in fecal until test results came back. Since then,
fecal levels have been normal along with all other test and there was no environmental damage caused by this
incident.
We thank you for your consideration of this matter. If you have any questions or comments, please call Kevin
Powell at 910/625-9771.
Si rely,
Damon mps n Manager
Town of Lake Wacca aw
