Subject: Request for NPDES Renewal
NPDES Permit#NC0048861
Town of Creswell
Creswell WWTP
Washington County
Dear NPDES Unit:
The Town of Creswell is submitting the renewal application package for NPDES#NC0048861. The permit
expiration date is December 31,2022. The renewal application package consists of:
• Cover letter
• Renewal application form—Application Form-2A(Revised 3-19)with tables A,B,and D
• Topographic map
• Schematic of WWTP(with water balance)
• Plant Narrative
The Town would like to make the following comment regarding the permit renewal:
• The current permit has a quarterly monitoring requirement for Mercury. We request that
monitoring for mercury be reduced to once per permit cycle per the Division's Mercury Post-
TMDL Permitting Strategy (September 12, 2012) for minor municipal systems. Test
results for mercury during this permit cycle have all been below the detection limit.
• The following corrections are needed for the Supplement Page for authorized components:
o Two lagoons in series—Can be removed from the permit as they have been abandoned
o Two mechanical fine bar screens—there are three(3)bar screens
o Two 42,300 anoxic basins each with a 2.3 hp submersible mixer— Should be removed,
there is not a second set of anoxic basins
We thank you for your consideration in these matters. If you have any additional questions or comments,
please call contact Ryan Swain,WWTP Superintendent at 252-796-7957 or [e-mail].

Creswell WWTP
NPDES NC0048861
Plant Narrative
The Creswell WWTP is an advanced WWTP utilizing the Membrane Bioreactor(MBR) process.
The influent flow to the WWTP is from the Town of Creswell and Tyrell County Water and
Sewer Districts 1 & 2. Both sewer collection systems are Septic Tank Effluent (STEP) systems
that greatly reduces the amount of solids from the influent flow stream. The current average
daily flow is 0.03 MGD and the facility is permitted for 0.20 MGD.
Flow from both systems enter the Influent Flow Splitter Box via forcemains. The fixed weirs
direct flow to either the WWTP or to the equalization pond. The flow continues to the influent
force main where the flow is metered and pumped to two mechanical screens.
After screening, the flow proceeds to the influent splitter box where the flow can be directed to
the two treatment trains. Each train consists of:
• Anoxic Basin with mixers
• Aerobic Basin(BODS and Ammonia Nitrogen removal)
• MBR Tanks (separation of solids from treated wastewater)
Support equipment for the treatment process include: Permeate Pumps, Internal Recirculation
Pumps, Return Activated Sludge Pumps, Waste Activated Sludge Pumps, Blowers for the
Aerobic Basin and MBR system.
The filtrate from the MBR flows to the UV disinfection system flows to the Cascade Type Post
Aeration System and to the Effluent Pump Station for final discharge to the receiving stream.
Waste Activated Sludge is pumped to the two Aerobic Digesters/Stabilization Tanks and are land
applied as needed.
