Mick: I'm working to see if the town has a portable generator that will handle the load for this
station. I think its our best option.

Subject: RE: [External] RE: RE: Nelson Street Pump Station - Pump Replacement
John —Thanks for the call back today. As we discussed, the existing pump station will have an
average daily design flow greater than 15,000 GPD, which requires this project to have a permanent
standby power source or pump per 15A NCAC 02T .0305(h)(1).
Based on a preliminary review, the application package requires the following additional information
before it can be processed further:
• The receiving WWTP permit number needs to be included in Part IV. of Item (1) of the
application.
• The project flow needs to be adjusted in Part VI. Item (7) of the application per your email of
March 10th. In addition, Part VI. Item (8) also needs a project flow value.
• Since the project design flow exceeds 15,000 GPD, the box for standby power source or pump
with automatic activation and telemetry needs to be checked in Part VIII. Item (6) of the
application.

• Additionally, it would be helpful to our understanding if you could provide an explanation as
to why the pump station and force main was oversized to begin with and what the expected
future services will be that become tributary to the pump station over its expected service
life.
Please send me the revised pages of the application once completed. Should you have any
questions, please do not hesitate to contact me. Thanks, Mike.

Mike:
I adjusted the daily flow to 13,200 gallons per day which we think is more in line with what the flow
will be in the near future. This gives us a 2 times per hour cycle time. The system is somewhat
oversized because the force main is existing, and we don't want to replace it. We oversized the
pumps to get the flow up over 2ft/second, which we felt was more important than the cycle time per
hour.
Thanks, John

John —This is a follow-up to the voice mail I left you today regarding the above pump replacement
project. Please see the additional questions below:

• Can you elaborate as to why the pump station and force main are so oversized for 975 GPD?
• Additionally, the application only specifies a portable pumping unit for power reliability. The
regulations require permanent backup power or a permanent standby diesel pump diesel
pump for pump stations with an average daily design flow greater than 15,000 GPD [15A
NCAC 02T .0305(h)(1)(C).
• And lastly, with an oversized PS/FM, will the system be able to meet the required 2-8 pump
cycles per hour for current actual flows?

Mike: The current flow is only 975 gallons per day. The larger number a maximum future flow that
the station could handle. The pumps had to be oversized to get the 2 ft/sec minimum velocity in the
existing 8-inch force main.
