This letter is sent in response to a Notice of Violation (Tracking Number NOV-2020-LV-
00231) issued to the above -referenced facility due to exceedance of permit limits during January
2020.
While ONWASA does not dispute the basis for this NOV (as the test results were self -
reported), facility staff continue to work diligently to adjust what remains a fully manual treatment
process in order to meet permit requirements. These efforts include additional process control
testing at multiple stages in the treatment process, adjusting the duration and number of SBR
batches processed per day, and working with representatives from an outside Professional
Engineering firm (WK Dickson and Company) under multiple contracts to assist with plant
operation as well as design of repairs to various systems damaged by flooding during Hurricane
Florence.
As an update to the flood recovery effort, construction is now underway on the first repair
project (restoration of the plant's disc filtration and UV disinfection systems), with a second
construction contract to restore electrical and control systems planned to be advertised for
competitive bid by the end of May 2020. We hope to have all plant systems and automated
controls fully operational again by July 1, 2021 at the latest.
ONWASA takes permit compliance very seriously and will continue to work concurrently
on both operational issues and recovery projects. If you have any questions of need additional
information please feel free to contact me directly at 910-937-7521 or dmohr(a)-onwasa.com.
