NPDES Permit #NC0026921
Robeson County
Dear Permitting Unit:
The Town of Parkton is submitting the renewal application package for NPDES permit
#NC0026921. The permit expiration date is July 31, 2019. The permit application
package consists of:
- Cover letter
- One original of Form 2A—NPDES Application for Permit Renewal, Parts: A, B, C and E
- Topographic Map
- Process Flow Schematic and Narrative
- Two additional copies of Renewal Package
The Town would like to request the following changes to the permit:
• The permit currently contains a quarterly monitoring requirement for mercury. We are
requesting that the monitoring be changed to reflect the monitoring requirements per the
NC DWR Mercury Post-TMDL Permitting Strategy (September 12, 2012). Based on
our understanding of the strategy, as a minor municipal facility, we should only have to
monitor once every five years. The wastewater flow to the plant is entirely
domestic/commercial with no known contributors of mercury, such as dental offices.
• The Town requests that quarterly monitoring for Chronic Toxicity be removed from the
peilnit. In your online guidance, there is an August 2, 1999 memorandum that states that

toxicity testing will be required at "major" facilities or those facilities discharging
"complex"wastewaters. The flow to the WWTP is a combination of domestic discharges
from residential and commercial sources with no industrial contributions and should not
be subject to the toxicity requirement.
• It is requested that the upstream and downstream monitoring requirements for Dissolved
Oxygen and Temperature be removed from the permit. The receiving stream flows through
swampland/woodland that is bordered by farmland. The testing of DO and Temperature
at the two monitoring sites has no correlation to the discharge from the wastewater plant.
DO in the stream is more likely to be affected by agricultural runoff,natural decay,rainfall,
etc. and any increase or decrease in DO cannot be definitely attributed to the treatment
plant. Again,since the wastewater flow is domestic in nature with no industrial dischargers
that could potentially discharge high temperature waste it is improbable that the discharge
will affect stream temperature.
• It is requested that conductivitymonitoringbe removed from the permit. A review of test
q
results shows that the conductivity of the effluent is consistently in the range for domestic
wastewater. As the wastewater is purely domestic, any changes in the conductance of the
water would be attributable either to temperature or potable water characteristics. Current
permit required testing for BOD5,TSS,and NH3 are sufficient to determine effluent clarity.
• We request that condition A. (3.)Sludge Monitoring Requirements be removed from the
permit. This requires the Town to test the biosolids twice per year for mercury. Any waste
sludge generated by the WWTP is dewatered on the sand drying beds and then taken to a
landfill for final disposal. The presence or absence of mercury in the biosolids can have
no environmental impacts. Secondly, due to the low influent BOD5, the plant may not
produce waste sludge for years at a time. With no waste sludge,the Town could not meet
this requirement.
We appreciate your consideration of these requests. If you have any questions or
comments, please contact Roy Lowder, WWTP Operator in Responsible Charge, at
910-975-4715.
Sincerely,
Al McMillan, Mayor

Treatment Plant Narrative
NPDES NC0026921
The Town of Parkton WWTP consists of the following units:
• Barscreen
• Two parallel operating oxidation ditches
• Two parallel operating secondary clarifiers
• Two sludge recirculation and waste pump stations
• Parshall flume and flow meter
• Chlorine contact basin
• Post aeration
• Aerobic sludge digester
• Sludge drying beds
The Parkton WWTP is an activated sludge system using oxidation ditches for aeration and
conventional clarifiers for sedimentation. Each clarifier is equipped with a sludge pumping
station which can be used to recycle the activated sludge to the aeration process or waste the
sludge to the aerobic digester. Effluent from the activated sludge process is disinfected in the
chlorine contact basin and then dechlorinated. After disinfection,post aeration is accomplished
by cascade steps to insure maintenance of minimum dissolved oxygen levels.

SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING 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.
• At a 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 alternate 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
complete.
