The City of Kings Mountain holds NPDES Permit NC0020737. On July 18, 2016, the City (Pilot
Creek WWTP) received the signed Special Order by Consent by the Environmental Management
Commision. This Order states Status Reports are due on the 111 day of Jan., April, July and
October of every year until May 31, 2018 in the Scheduled Activity section, Section 2. (b).
As you are aware, Steag Energy Services' is the only SIU that is known to release thallium into
the City of Kings Mountain's collection system. According to permit #0032, issued by the City of
Kings Mountain, Steag is to monitor thallium at their final discharge point monthly. Depending
on the results obtained from an approved contracted laboratory, this monitoring frequency is
subject to change.
Pilot Creek will continue to monitor for thallium, as instructed on the Special Order by Consent,
to obtain compliance with the formentioned consent.
The following data has been obtained for thallium from Pilot Creek for comparrision to the
monthly data received from Steag Energy Services:

Pilot Creek is continuously running the onsite belt press in order to reduce the amount of
thallium in the effluent. Steag Energy informed the City that they will send the products that
they believe contains the higher levels of thallium to their Charlotte facility. This should help
reduce the amount of thallium in the effluent at Pilot Creek.
The City of Kings Mountain will continue to work diligently toward the removal of thallium at
the Pilot Creek WWTP through disposal (to the Cleveland County landfill) of sludge from the
belt press. We have decided to have quarterly meetings with Steag to discuss steps they are
making to reduce thallium in their effluent.
If you have any questions, feel free to contact me anytime Monday -Friday 7:30a-4:OOp
Sincerely,
Richelle Meek
