Re: Compliance Evaluation Inspection
Henderson Water Reclamation Facility
NPDES Permit NCO020559

Dear Mr. Bolich:
Thank you for the Compliance Evaluation Inspection performed on January 31, 2019 by Vanessa
Manuel of the Raleigh Regional office. In response to follow up information requested for item
number 2 and 10(b), please note the following information:
Item 2 — Abandoned treatment units that are no longer part of the wastewater treatment
process
When the wastewater treatment plant was upgraded, there were insufficient funds to
remove all of the units that would no longer be used. Alternate bids were taken but not
awarded. This has been discussed with the Public Works Committee of the Henderson
City Council, and they have agreed with staff that bidb should be obtained to see what the
demolition cost would be. This will take approximately 45 days to obtain, and once the
figures are obtained the City Council will consider the bids and the appropriate funding
source. An Earlier quote obtained when the initial construction work was being
completed to get this work done was approximately $656,374, so there is significant cost
associated with the demolition. If okay with your office, I would like to report back on a
more definitive date to complete or plan of action, once bids are taken.
Item I0(b) — Secondary Treatment — the depth of clarifiers is as follows per Lamont
Allen:
The clarifiers are 20'-0" deep. It was indicated that #1 was stopping up and this was
corrected and the clarifiers equalized to 5.5 ft. The City is working diligently with
Granville Farms to reduce the level of solids in the clarifiers; however, this has been
tough to fully address due to wet weather.

1f you have further questions or concerns please feel free to call Lamont Allen at 252-431-6081
or via email at lallen'rr'ci.11eiiderson.nc.us or myself at 252-430-5701 or
