As town manager and the responsible party for the Tabor City W WTP (NPDES # NC0026000) I herein
request the renewal of our plant's NPDES discharge permit. The plant has not been modified since the
last renewal but repairs to the existing equipment are imminent. We will soon repair the piping associated
with one clarifier to increase its efficiency in solids removal but treatment capacity and functioning of the
plant will remain the same.
Attached are signed originals and the required copies of the completed NPDES application Form 2A with
exhibits, and a statement from our sludge handlers.
Please contact me with any further requirements you may have.
Thank you
Al J. Leonard, .

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/OC 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 I 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 forth to
complete.

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 4o 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 QArQC 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 whale effluent toxicity test
conducted during the past four and one -hall years revealed toxicity, provide any information on the cause of the toxicity or any results of a toxicity
reduction evaluation, it 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 EA 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 biomonitormg data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to

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 EA 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.

Flow Balance Diagram

FLOW BALANCE NOTES:
In calculating the material
bolonce flows for the
Tabor City
WWTP, the WAS
flow is
estimated at 350 GPD. Of
that 350 gallons, the
equivalent
of 300 gallons
per day is
periodically decanted out of
the Sludge Digester
returned to
the headworks.
The remaining
50 gallons per day of thickened
solids remains
in the tank
until hauled. These WAS flows
are insignificant compared
to the plant process
flows and are not included
within the
water balance diagram but
ore contained within
the plant.

PLANT NARRATIVE:
Influent flow foils into the plant influent pump station (ps), excess flow can be
diverted to the equalization basin for later treatment. The influent ps transfers the
untreated waste stream to the headworks where it is screened through either a
mechanical or manual barscreen and metered. The influent flow then posses into a
splitter box where 55% is diverted to Basin #2 and the balance of 45% is
conducted to Aeration Basin #1. These percentage partitions ore proportional to the
size of the respective aeration basin. After the aeration basins the two MLSS flows
enter two clarifiers for solids settling. The flow over the clarifier weirs is
approximately half of the aeration tank flow while the remaining flow exits the
bottom as RAS flow returning to the aeration basin from which it came. The weir
flows from the two clarifiers then flows into o single Chlorine contact chamber for
disinfection. The final course of the Chlorine contact chamber is fitted with a
dechlorinotion feed of Sulfer Dioxide and well mixed by aeration before discharging
from the plant.
