Re: Response to Notice of Violation & Intent to Issue Civil Penalty
Tracking No. — NOV-2021-DV-0174
Sanitary Sewer Overflows — February 2021
Henderson Collection System
Permit No. — WQCS00055
Dear Mr. Vinson:
I am writing in response to the above mentioned violation that we received on March 30, 2021. The
overflows in each incident were due to inflow and infiltration during extended periods of heavy rainfall.
Once the rain event ended, the overflows subsided. Following the overflows, we cleaned debris and
placed lime as needed. We continue to search for sources of 1/1 via smoke testing and CCTV equipment.
Moving forward, Henderson City Council has approved a CIP project for an EQ basin at the Sandy Creek
Pump Station for fiscal year 2020-2021. This project is contingent on council allocating the funds for the
project. The EQ basin will increase capacity at the pump station to help prevent spills.
Henderson has also hired a consultant, WK Dickson, to assist our efforts in reducing 1/1. WK Dickson has
started a sewer model that will help us assess the problem areas in our system. With their help we have
received a letter of intent for a loan in the amount of $2.5 million from the Clean Water State Revolving
Fund for sewer rehabilitation in an effort to alleviate sources of 1/I. The Henderson City Council voted
unanimously to accept this funding at its March 8, 2021 Council meeting. Further, on April 12, 2021,
the Henderson City Council approved a contract with WK Dickson to begin work on this project.
We take our responsibility to maintain compliance for our collection system very seriously. Public Works
is working closely with Engineering and HWRF to come up with solutions to fight our 1/1 problem. I trust
that you find the City's actions for compliance are satisfactory. Thank you very much for the opportunity
to respond. Please feel free to contact our staff or myself should you need any further information.
Sincerely,
/eeen
Assistant Public Works Director
