Dear Mr. Kanipe:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant
to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as
subsequently amended).
This final permit includes the following changes to its terms from those found in the draft permit sent to
you on October 9, 2013.
• A new condition requiring electronic reporting of data collected pursuant to the terms of this permit
has been added.
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specify that, if a state does not establish a system to receive such submittals, then permittees
must submit DMRs electronically to the Environmental Protection Agency (EPA). The Division
anticipates that these regulations will be adopted and is beginning implementation.
The requirement to begin reporting discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application has been added to your final

Permit NC0021369
A. (2). CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 37%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the
"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent
versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February
1998) or subsequent versions. The tests will be performed during the months of March, June, September, and
December. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent
discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below
the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that
does have a detectable impairment of reproduction or survival. The defmition of "detectable impairment,"
collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase
II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR 1) for the months in which tests were performed. If reporting pass/fail results using the
parameter code TGP3B, DWR Form AT-1 (original) is sent to the below address. If reporting Chronic Value
results using the parameter code THP3B, DWR Form AT-3 (original) is to be sent to the following address:
Attention: NC DENR / DWR / Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is
employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating
the facility name, permit number, pipe number, county, and the month/year of the report with the notation of
"No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences
Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Water Resources indicate potential impacts to the receiving stream, this permit may be re -opened and modified
to include alternate monitoring requirements or limits.

A. (2). CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY), continued
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT
Forms submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, �ininimum control organism reproduction, and appropriate environmental controls, shall
constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day
of the month following the month of the initial monitoring.
A. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specify that, if a state does not establish a system to receive such submittals, then permittees must
submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates
that these regulations will be adopted and is beginning implementation in late 2013.

Permit NC0021369
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements may
be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1, 2, 3)
or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the date the
facility would be required under this permit to begin using eDMR. Temporary waivers shall be
valid for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
electronically to the Division unless the permittee re -applies for and is granted a new temporary
waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr

the wastewater discharged during the sample period.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et.
seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which is
not a designed or established or operating mode for the facility.
Calendar Day

Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval
between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite
samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period
of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with
the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow
measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the
preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system, or

Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample," above.)
Daily Maximum
The highest "daily discharge" during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).

The Division of Water Quality, Depailinent of Environment and Natural Resources.
Effluent
Wastewater discharged following all treatment processes from a water pollution control facility or other point source
whether treated or untreated.
EMC
The North Carolina Environmental Management Commission
EPA
The United States Environmental Protection Agency
Facility Closure
Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this
permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and (j) and 15A NCAC 02H .0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.

(8)
c. The Permittee shall investigate the source of all discharges into the POTW, including slug loads and other
unusual discharges, which have the potential to adversely impact the Permittee's Pretreatment Program and/or
the operation of the POTW.
The Permittee shall report such discharges into the POTW to the Director or the appropriate Regional Office.
Any information shall be provided orally within 24 hours from the time the Permittee became aware of the
circumstances. A written submission shall also be provided within 5 days of the time the Permittee becomes
aware of the circumstances. The written submission shall contain a description of the discharge; the
investigation into possible sources; the period of the discharge, including exact dates and times; if the
discharge has not ceased, the anticipated time it is expected to continue; and steps taken or planned to reduce,
eliminate, and prevent reoccurrence of the noncompliance,

600 KW backup generator.
Update: August 2, 2014
Sludge & grit removal from the aeration basin: a local contractor with an excavator (working with CYP Tryon),
will give the Town a bid for removal of sludge and grit from the aeration basin.
The WWTP site is currently under construction. The engineer / contractor is WK Dickson. They are excavating
the site now.
In addition to the A to C components, they are getting a new potable water well & a new lab/office building.
They will also rewire the blower motor controls & starters. They will have all new electrical system components.
The estimated completion date is May 1, 2014.
The phone line to the WWTP has been destroyed, as a result of construction. Here are the contact numbers:

Bob,
Kim Colson sent a letter of acknowledgement on 12-21-2011 for the Wastewater System Improvements Engineering
Report (SRL Project) submitted by WK Dickson (received by Construction Grants & Loans on June 30, 2011 and by DWQ
ARO on July 11, 2011).
I do NOT think that we need to include a special condition in the next permit regarding an Aeration Basin Hydraulic
Study.
Let me know if this answers your questions. Call or email me anytime.

RE: Town of Columbus, NC
We have had numerous discussions with the Town regarding the project. And, we would be happy to have them
participate in a phone call.
Specifically, we want to discuss the following with you:
1. disposition of the existing aeration basin
2. water at the site.
3. any indication of future nutrient limits

4. anything else that may be of concern or on the Department's radar concerning this facility
However, far your information, other items included in the rehab include the following:
1. Bar Screen / Grit Removal -- A new automated fine bar screen will be added to the WWTP in order to add
redundancy to the existing manual coarse bar screen. In addition, grit removal will be added to the headworks.
2. Aeration Basin -- Solids that have collected over time in the aeration basin will be removed and disposed of
before any further work occurs inside the aeration basin. Upgrades to the basin may indude removal and
replacement of the existing metal bulkhead.- However, removal has -presented an issue because it -would lead
to an extended detention time and result in ultimate additional aeration / additional energy consumption.
3. Existing Clarifier -- The existing clarifier mechanism will be replaced. The interior portions of the existing clarifier
will be coated. A new FRP weir and Stamford baffle will be installed in the clarifier. Minor pumping, valving and
control improvements will also be performed.
4. Proposed Clarifier— A new, second clarifier including additional RAS/WAS pumping and piping and associated
appurtenances to add redundancy.
5. Power Distribution / Motor Control Center (MCC) -- A new, enclosed MCC and electrical building will be
constructed to replace the existing, exposed MCC and the motor controls power distribution equipment
replaced.
6. Demolition — Demolition of existing components will include the sludge drying beds, the sludge
digester/decanter, and sludge storage basin.
7 Sludge Digestion & Storage Tankage -- A new 200,000+ gallon sludge digester tank and sludge storage tank will be
constructed.
8. Disinfection Instrumentation -- Upgrades will include flow proportional control of the addition of disinfectant and
dechiorination.
9. Site Improvements — Improvements will include grading, paving, piping, erosion control, and seeding.
10. Electrical Upgrades — Improvements will include the installation of a SCADA system and permanent, standby
emergency generator with associated electrical
improvements.
11. Redundant Chlorine contact chamber— the Town is considering the addition of a redundant, 2" chlorine contact
chamber in an effort to improve operation and
maintenance.
12. Office / lab — the Town is considering replacing their WWTP office / lab due to O&M concerns associated with the
existing building.
FYI — this project is being funded by an SRF loan.
Again, we can either discuss by phone. Or, if you would prefer, we would be happy to meet with you. Let us know what
is more preferable and two or three times / date that are convenient for you.

Don,
We would like to talk to you about our current project with the Town of Columbus. As you may or may not be aware,
the town has a contract to design SRF funded improvements / rehabilitation to upgrade their WWTP. The project will
add no new capacity. Currently, we wanted to discuss the disposition of the current aeration basin with you.
Can you please let us know a convenient time to get in touch with you and we will give you a call? Thanks.

Hi Folks,
I'm working on the renewal of the permit for the Columbus WWTP (NC0021369). Y'all were shown on BIMS to be the
last inspectors of the facility, so I'm throwing this question your way.
The existing permit has a special condition that called for an Aeration Basin Hydraulic Study to be submitted to ARO by
November 1, 2008. Do you know if it was submitted? If it wasn't, does it matter now? Does such an issue exist that
we'd want to include the condition again in the next permit? We've got copies of recently issued AtoCs in our file.
There's one from February 2013 that appears to supersede one issued in September 2012. The earlier one called for
installation of new aerators in basin 2 (among other items). The later one included d authorization for installing some of
—the same equipment, some new units, but did not mention the aerators.
Bottom line: should I leave the condition in the permit?
Thank you,
Bob

The Town of Columbus WWTP is a minor municipal facility, currently with no significant industrial discharges
and no pretreatment program. The Town's permit includes monitoring for a variety of metals and toxicity
because in the past industrial discharges did flow to the WWTP. The pretreatment program has been inactive
for about 19 years:
A RPA was performed using data provided by the facility from January 2010 through April 2013. Its results
yielded the following changes to the permit's terms
Cadmium: Limit removed; monitoring reduced to quarterly.
Copper: Althou0 RP was noted in the analysis, monitoring was reduced to quarterly because the parameter
has an action level.
Cyanide: Limit removed; monitoring reduced to quarterly.
Lead: Limit removed; monitoring reduced to quarterly.
Silver: Although RP was noted in the analysis, monitoring was
has an action level.
Zinc: Although RP was noted in the analysis, monitoring was
has an action level.
The limit for mercury was removed pursuant to application of guidance for implementation of the statewide
mercury TMDL. However, because an incorrect mercury limit (32.3 µg/L) was included in the 2008 permit, the
facility did not report any values during the permit cycle using the low level method, and the results (all reported
as <0.2 µg/L) were of no use in the evaluation. Therefore, data from the previous permit cycle were reviewed.
reduced to quarterly because the parameter
reduced to quarterly because the parameter
IWC = 37% Dilution Factor = 2.7
Allowable Hg = 32.4ng/L Pre 2009 average Hg = 9.6 ng/L
No value > 47 ng/L
Because there is no recent good data from the facility, an annual monitoring requirement was added rather than
the once per the permit cycle monitoring suggested by the guidance. This will provide a few more data points to
review at the time of the next renewal.

A.Procedure to Determine if Annual Average Limit Required:
� 4
Step 1- WQBEL Evaluation
• Evalu to need for Water Quality Based Effluent Limit (WQBEL)
• Calculate Allowable mercury concentration using dilution (12 ng/1 x 7Q10 dilution factor)
• Compare Annual effluent concentrations to Allowable Conc. for each of last 5 years
• If any Annual Avg > Allowable Conc., then add Annual Avg WQBEL.
Step 2- TBEL Evaluation
• Evaluate need for Technology Based Effluent Limit (TBEL)
• Compare all individual values to TBEL of 47 ng/1
• If any single value > 47 ng/1, then add Annual Avg TBEL of 47 ng/1.
Step 3- Compare WQBEL to TBEL
• If datairiggers need for WQBEL and TBEL, select most stringent of the two limits.
• The Annual Avg limit will be capped at 47 ng/1 based on TBEL.
Step 4- If NEW limit, delay effective date
• Addition of new limit will become effective in 5`h year of permit, with mercury minimization plan
development/implementation required for first 4 years (see MMP below).
B. Mercury Minimization Plan (MMP). If an MMP is required, add the following Special Condition to
the permit:
A(x). Mercury Minimization Plan (MMP). The permittee will develop and implement a mercury
minimization plan during this permit term. Guidelines for MMP development will be placed on the
Division website following a stakeholder review process. The MMP should place emphasis on
identification of mercury contributors and goals for reduction. Results shall be summarized and
submitted with .the next permit renewal. The MMP must be available for inspection on -site.
C. New/Expanding Dischargers- will be allowed as long as the overall aggregate point source load
allocation is not exceeded.
D. Special Situations- Additional site -specific information, such as fish tissue and water column data
when available, will be considered in assigning limits and MMP requirements. Also, limits > TBEL may
be considered on case -by -case basis due to extenuating circumstances.
