RETURN RECEIPT REQUESTED
Dear Mr. Weavei.
This serves as a request by the City of Wilson to renew NPDES Permit No. NC0023906. Enclosed are one signed
original and two (2) copies of the permit renewal package as required including a Residuals Management Plan. The
City’s permit expires May 31, 2013.
The City of Wilson respectfully requests that the November 9, 2011 version of Part II - Standard Conditions for
NPDES Permits" be incorporated into our renewed permit.
Also, as per NCDENR document “D WQ Guidance Regarding the Reduction of Monitoring Frequencies in
NPDES Permits for Exceptionally Performing Facilities" dated October 22, 2012, we respectfully request that the
monitoring frequencies for BOD5, TSS, NH3-N, and Fecal Coliform be reduced to the recommended twice per week
minimum. The City of Wilson Hominy Creek Water Reclamation Facility is an Exceptionally Performing Facility.
For your review, please see attached document, "Justification for Reduction of Monitoring for City of Wilson
Hominy Creek Water Reclamation Facility, NPDES Permit No. NC0()23906".
In addition, the City of Wilson also requests the following changes be incorporated into the renewed permit:
1. Removal of weekly average and daily maximum limits for Total Cadmium and also removal of the
weekly monitoring requirement. This parameter would continue to be monitored as required during
the Effluent Pollutant Scan (aka: Priority Pollutant Analysis, or PPA).
2. Removal of additional monitoring requirements for Total Copper, Total Zinc, Chloroform, and
Dichlorobromomethane. These parameters would continue to be monitored as required during the
Effluent Pollutant Scan.
3. Reduced monitoring for Dissolved Oxygen, Total Residual Chlorine, Temperature, Conductivity, and
pH from Daily to 2/Week.
4. Reduced monitoring for TKN, NOrN + NO3-N, Total Nitrogen, and Totai aosptorui.fem yeekly to
Monthly.
5. Reduced monitoring for Chronic Toxicity from Quarterly to 2/year.
6. Removal of stream monitoring requirements.

• For BOD5, TSS, NH3-N, and Fecal Coliform, the three year arithmetic mean of effluent data is less than
50% of the monthly average limit.
• No more than 15 daily sampling results over the 3 year review period exceeded 200% of the monthly
average limit for BOD5, TSS, and NH3-N.
As per NCDENR’s document 'DIPQ Guidance Regarding the Reduction of Monitoring Frequencies in NPDES
Permits for Exceptionally Performing Facilities'" dated October 22, 2012, we respectfully request that the
monitoring frequencies for BOD5, TSS, NH3-N, and Fecal Coliform be reduced to the recommended twice per week
minimum.
The City of Wilson Hominy Creek Water Reclamation Facility is an Exceptionally Performing Facility and has
demonstrated consistent, long-term treatment performance at levels far below effluent limitations (<50%) and
should be considered for a reduction in monitoring from existing permit frequencies to a 2/week minimum
frequency for BOD5, TSS, NH3-N, and Fecal Coliform. Our facility meets all of the approval criteria for this request
as outlined in the document:
• The facility has not experienced a civil penalty assessment for permit limit violations for each target
parameter during the previous three years.
• Neither the permittee, nor any of its employees, have been convicted of criminal violations of the Clean
Water Act within the previous five years.

• Reduced effluent monitoring will not impair assessment of sensitive downstream uses, such as endangering
species.
All of the above referenced data has been previously submitted to NCDENR-DWQ as required via monthly DMRs.
However, if needed, the City of Wilson will submit detailed data summaries upon request. If you have questions or
need additional information please contact me at [phone], or via email at [e-mail].
• No more than 20 daily sampling results over the 3 year review period exceeded 200% of the weekly

Biosolids generated at the Hominy Creek facility are stabilized to a Class B residual b>
anaerobic digesters or to a Class A residual by an alkaline sludge stabilization process
prior to disposal by land application or disposal to a regional compost facility.
Anaerobically digested sludge (ADS) is pumped from the sludge holding tanks and
conveyed to two (2) belt filter presses (BFP) located in the dewatering building. Liquid
polymer feed facilities provide effective dewatering of the ADS. Dewatered sludge is
discharged from the BFP directly onto a conveyor belt and then to the sludge storage pad
or to the alkaline stabilization facility. The dewatered sludge cake has a solid
concentration of 20 to 25 percent.
Alkaline stabilization is provided in order to produce a Class A biosohds product under
the 40 CFR Part 503 sewage sludge regulations. A series of conveyors deliver the
dewatered sludge cake to the alkaline stabilization facility. Lime and supplemental heat
are added to the sludge cake in a lime-sludge blender to raise the temperature and adjust
the pH. Supplemental heat is added to boost the temperature to pasteurization levels.
Temperature is maintained at or above pasteurization temperature levels during passage
through a plug flow pasteurization vessel conveyor. Lime is stored in a 66-ton lime silo.
Dewatered and stabilized biosolids are land applied to permitted privately-owned
farmland or transported to a privately-owned composting facility. A 32,000 sq. ft.
covered storage pad provides storage for periods when solids cannot be land applied.
Granville Farms, Inc operates the City of Wilson land application program. The program
requires full time operation, normally 5 to 6 days per week and 8 to 12 hours per day.

uncompleted plans for improvements that will affect the wastewater treatment, effluent quality, or design capacity of the treatment works. If the
treatment works has several different implementation schedules or is planning several improvements, submit separate responses to question B.5
for each. (If none, go to question B.6.)
List the outfall number (assigned in question A.9) for each outfall that is covered by this implementation schedule.

Part B., B.3.
Plant Description
The two (2) preaeration basins shown on the schematic (Figure 1-2) are no longer in service.
The Hominy Creek Water Reclamation Facility (WRF) is located south of the City of Wilson on
SR 1602. Plant effluent from the facility is piped through approximately 7,700 feet of 48-inch
outfall to Contentnea Creek. The discharge point is approximately 2.5 miles downstream of the
Wiggins Mill Reservoir dam. Wastewater is conveyed to the Hominy Creek WRF by the
Hominy Swa.np, Contentnea and Toisnot Swamp interceptors. Flow enters the plant tluough the
36-inch Hominy Swamp Interceptor, the 30-inch Contentnea Interceptor and the 20-inch force
main from the Toisnot Pump Station. A separate influent pump station at the treatment plant site
conveys wastewater from the Hominy Swamp and Contentnea Interceptors to the preliminary
treatment facilities.
As shown in Figure 1-2, the Hominy Creek WRF provides tertiary treatment, including nitrogen
and phosphorus removal, for a design capacity of 14 mgd. Raw wastewater from the off-site and
on-site pump stations receives preliminary treatment by screening and grit removal before being
conveyed to the primary clarifiers. From the primary clarifiers, How is distributed to the
biological nutrient removal (BNR) activated sludge stage. Major process units of the BNR
activated sludge stage consist of a biological phosphorus removal (BPR) tank, seven (7) aeration
tanks, five (5) secondary clarifiers and three (3) return activated sludge (RAS) pumping stations.
Secondary clarifier effluent receives tertiary treatment in five (5) effluent filters and is then
aerated and disinfected in two (2) post aeration/chlorine contact tanks to meet DO and fecal
coliform effluent limits. The effluent is then dechlorinated at the end of the post aeration/chlorine
contact tanks to meet a total residual chlorine effluent limit, and is discharged to Contentnea
Creek through the 48-inch outfall.
PartB.,B.3.
The solids handling facilities for the primary and waste activated sludge consist of two (2)
gravity belt thickeners for waste activated sludge thickening, four (4) anaerobic digesters for
solids stabilization, two (2) belt filter presses for dewatering, three (3) liquid sludge holding
tanks, an alkaline sludge stabilization facility capable of producing a Class A stabilized sludge
product and a covered sludge storage pad. The Class A dewatered sludge is disposed of by land
application on privately-owned farm land. The anaerobically digested Class B sludge is land
applied on privately-owned farm land or taken to a privately-owned composting facility.
Existing sand drying beds are available for standby dewatering or for use when draining a
digester for cleaning.
