City of Wilson Hominy Creek Water Reclamation Facility
NPDES Permit No. NC0023906
As per NCDENR's document"DWQ 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 continued at 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.
• The facility is not currently under a SOC for target parameter effluent limit noncompliance.
• The facility is not on EPA's Quarterly Noncompliance Report for target parameter limit violations.
• 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.
Parameter 3 year arithmetic mean Monthly Avg.Limit %of Monthly Avg.Limit
BOD5 1.1 mg/L 5.0 mg/L 22% (<50%)
TSS 0.14 mg/L 30.0 mg/L 0.5% (<50%)
NH3-N 0.06 mg/L 1.0 mg/L 6% (<50%)
Parameter 3 year geometric mean Monthly Avg.Limit %of Monthly Avg. Limit
Fecal 3 cfu/100 mL 200 cfu/100 mL 1.5% (<50%)
• 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.
o BOD: 200%of Summer monthly average limit of 5.0 mg/L equals 10.0 mg/L.
BOD: 200%of Winter monthly average limit of 10.0 mg/L equals 20.0 mg/L.
During the 3 year review period,no data exceeded 10.0 mg/L during the Summer and no data
exceeded 20.0 mg/L during the Winter.

Part B - Item 8.3.
Plant Description
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 Swamp, Contentnea and Toisnot Swamp interceptors. Flow enters the plant through 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, flow 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.
The two (2)preaeration basins shown on the schematic (Figure 1-2) are no longer in service.

Part B - Item 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.

SUPPLEMENTAL APPLICATION INFORMATION *Refer to previously submitted toxicity test data*
PART E. TOXICITY TESTING DATA *Refer to previously submitted toxicity test data*
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1)POTWs with a design flow rate greater than or equal to 1.0 mgd;2)POTWs with a pretreatment program(or those that are
required to have one under 40 CFR Part 403);or 3)POTWs required by the permitting authority to submit data for these parameters.
• Ata minimum,these results must include quarterly testing for a 12-month period within the past 1 year using multiple species(minimum of two
species),or the results from four tests performed at least annually in the four and one-half years prior to the application,provided the results
show no appreciable toxicity,and testing for acute and/or chronic toxicity,depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition,this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition,submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity,provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation,if one was conducted.
• If you have already submitted any of the information requested in Part E,you need not submit it again. Rather,provide the information
requested in question E.4 for previously submitted information. If EPA methods were not used,report the reasons for using altemate methods.
If test summaries are available that contain all of the information requested below,they may be submitted in place of Part E.
If no biomonitoring data is required,do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to
