Subject: Permit Application Return
NPDES No. NC0020389
Town of Benson WWTP
Wake County
Dear Mayor Johnson:
I received your request for modification of your NPDES permit to discharge. Specifically, you requested
that consideration be given to allow this discharge to be increased from 1.5 million gallons per day (MGD)
to 1.732 MGD. After discussions with Mr. Keith Langdon (Town Administrator) and Eric Mills (The Wooten
Company), the Division is hereby returning this request with the following comments.
First, as you may know, the water quality in the Neuse River basin has prompted the Division to
reevaluate the existing Nutrient Sensitive Waters Management Strategy. The modified strategy has not
been finalized, but will likely include limits for total nitrogen for any expanding discharge. The town
should consider this when making future plans to expand above 1.5 MGD.
Furthermore, the town should perform an alternatives analysis as described in the attached document
for any expansion. Please note that there is a provision for the requirements regarding soils analyses for
expanding discharges greater than 1.0 MGD.
Finally, the Town of Benson will need to submit a completed NPDES application form (Standard Form
A) with any resubmittal. If you have any questions or comments, please do not hesitate to contact me at
(919)-733-5083, extension 517.
Sincerely,
David A. Goodrich
NPDES Group Supervisor

The Town of Benson hereby requests that the above referenced permit, issued to the Town, be modified
to allow an average monthly discharge of 1.732 million gallons per day. This is the maximum monthly average
discharge rate that an engineering study shows our treatment plant can handle without any physical
modifications. Infiltration and inflow have caused plant flows to reach, and, at times, exceed our currently
permitted capacity of 1.500 million gallons per day. Increasing the permitted capacity of the plant will allow the
Town to continue to grow and to operate its treatment plant without permit violations while it continues to work
to eliminate infiltration and inflow sources. A $400.00 check for the permit modification fee, and three (3)
copies of the aforementioned engineering study, are enclosed in support of this request.
If any additional information is required, please let us know.
Sincerely
ael(11/
