Additional information
8/1/2018: The Pretreatment analyst performed the 2nd semi-annual sampling event at Cormetech.
During this event, Cormetech was found in violation for Arsenic. The result of this sampling was 6.0598
Ibds/day. Cormetech's arsenic limit is 2.2 lbs/day.The follow-up response to the violation stated they
believe a holding tank was discharged during the sample event that wasn't scheduled for discharge.
Since then, operators have been retrained with operating procdures.
10/03/2018: Phone conference with Cormetech to discuss arsenic violation(s) and thallium reduction
at their facility.
10/17/2018: Met with a rep from Sherwin Williams about coating the trofts inside of the clarifiers at
Pilot Creek.
12/17/18: Ricky Duncan onsite at Pilot Creek to discuss process improvements needed at the
facility to produce a higher quality effluent. We have come to the conclusion, Pilot Creek would benefit
by having a grit removal system. It is in the works on obtaining quotes for the systems.
A new conveyor belt and rollers were installed on the belt press at Pilot Creek. Belt press begin running
again on 01/3/19.
Pilot Creek WWTP continues to operate the belt press as much as possible to remove metals in the
system(s). During the timeframe of January-August, we have disposed of 854.4 tons of solids to the
Cleveland County Landfill. We will continue to operate the press in order to reduce the amounts of
solids in the system.

If you have any questions,feel free to contact me anytime.
Sincerely,
Richelle Meek
