Subject: Compliance Evaluation Inspection Response
Benson WWTP
NPDES Permit NCO020389
Johnston County
Dear Mr. Thomas
Please accept this
written response to the inspection
letter and EPA report received on February 25 ,
2020. The compliance inspection of the Town of Benson WWTP conducted by yourself and Jason
Robinson on Monday, February 17, 2020 was an opportunity for the plant staff to highlight the vast
amount of time and effort put into improving the equipment and operations at our facility. We believe
that the current condition of the facility, combined with the successful compliance record over the last
year, reflect well on the commitment the Town of Benson and the WWTP staff have towards
maintaining this facility both now and into the future. You were thorough in this inspection, and I
believe that your report accurately reflects the status of the plant. As we continue to work, we
appreciate your assistance and support in achieving our goals.
l
The following are the requested responses to the items outlined in the inspection report:
7. b) Grit removal system: This unit was reassembled by the contractor on February 17, 2020. On

and in use.
7 . d) Screw pumps : The motor for screw pump #3 was received at the plant on March 6, 2020 and 4

7 . e) Rotor #1 in Ditch #1 : Our electrician arrived on Thursday, February 20, 2020 and installed

7 . 1) Standby Power : A logbook has been created to track the plant generator usage and function.
The generator will be tested at a minimum of once per month if not having already been used
for emergency power or load management in that month. The logbook will also contain all
regularly scheduled servicing, emergency service repair calls, fuel contact infonnation and
refuel dates .
7 . m) Treatment lagoons : Plant operators utilize stationary staff gauges to measure the level of the
treatment lagoons daily. The locations of the staff gauges are shown on the inserted map as
marked by the yellow arrows .
