MOORESVILLE REGIONAL OFFICE
We appreciated the opportunity to speak with you concerning the non -compliant issues related to
the recent inspection of the West Stanly WWTP.
Pursuant to that conversation, Stanly County will proceed with the following plan of action to
address the noted violation items noted from the inspection:
01
Q
Potassium Permanganate chemical feed that was installed at the McCoy PS has been
dismantled and removed. It was determined that the chemical injection needed to be
further upstream in order to have any effect on odor control. All chemicals have been
disposed of and equipment removed.
Chlorine contact chamber was noted to have floating debris and grease build up on walls.
The contact chamber was cleaned and all floating solids removed 2/6/2019.
The Secondary Clarifier has not been working for some time from what I being told.
Our plans are to proceed to construction with a new larger clarifier and permanently
remove this the two non -working clarifiers.
Head -works mechanical bar -screen at McCoy PS has been repaired and put back online
on 2/13/2019 and is operating normally.

5. Stanly County Operational Staff has been deployed with vacuum trailer to remove grease
build up and clean out the influent channels. An electrician has been contacted to get a
fan switch installed at the top of the stairs to remove any danger of Hydrogen Sulfide gas
at head -works pump station. Shrubbery along the head -works fence line has been cut
back as requested by NCDEQ inspector. Additional warning signage has been put up at
the pump station. Additional warning and hazard signs will be installed on all sides of
the fence along with emergency contact phone numbers. This will be done at the W WTP
also.

loader provided by the Collection maintenance dept. will be used to remove all full trash
cans and any solids that are lying one the ground.
It is our intent to update you as all remaining item are getting completed.
