Subject: Issuance of NPDES Permit
Permit NC0024333
Monroe WWTP
Union County
Facility Class IV
Dear Mr. Colbath:
John-E. Skvarla, III
Secretary
Division personnel have reviewed and approved your application for a 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).
The following changes have been incorporated into this renewal:
• The weekly average limit for cyanide has been changed to monthly average in accordance with
the 40 CFR 122.45 (d) (2), which requires monthly average and daily maximum limits in the
permit.
• The effluent was evaluated in accordance with the Monitoring Frequency Reduction Review Guidance.
The facility has met the requirements of the guidance for BOD, TSS, ammonia nitrogen, and fecal
coliforms. Therefore, monitoring for these parameters will be reduced from daily to 2/Week.
• 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 the permit. [See Special Condition A. (5)]

A. (3.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 90 %.
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 definition 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 / Division of Water Resources

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 permitmay be re -opened and modified
to include alternate monitoring requirements or limits.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such
monitoring shall be included in the calculation and reporting of the data submitted on the DMR and all AT
Forms submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival, minimum 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.

Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that
Municipal facilities that are subject to the Effluent Pollutant Scan requirements listed above are also
subject to additional toxicity testing requirements specified in Federal Regulation 40 CFR
122.21(j)(5). The US EPA requires four (4) toxicity tests for a test organism other than the test
species currently required in this permit. The multiple species tests should be conducted either
quarterly for a 12-month period prior to submittal of the permit renewal application, or four tests
performed at least annually in the four and one half year period prior to the application. These tests
shall be performed for acute or chronic toxicity, whichever is specified in this permit. The multiple
species toxicity test results shall be filed with the Aquatic Toxicology Branch at the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the

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/ipuiedmr
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following
the commencement of discharge.
2. Signatory Requirements [Supplements Section B. (11.) (b) and supersedes Section B. (11.)
All eDMRs submitted to the permit issuing authority shall be signed by a person described in
Part II, Section B. (11.) (a) or by a duly authorized representative of that person as described in
Part II, Section B. (11.)(b). A person, and not a position, must be delegated signatory authority
for eDMR reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North
Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit
the following web page:
http://portal.ncdenr.org/web/wq/adminfbog/ipu/edmr

accordance with the 40 CFR 122.45 (d)(2), which requires monthly average and daily
maximum limits in the permit.
2) We still have an old batch of Standard Conditions, which lists the Division of Water
Quality. We print these documents in bulk to save money. When the old batch runs
out, we will be using a new batch with the new name.
Thank you!

Dear Mr. Chernikov:
CITY
OF
MONROE
a heritage of progress
The City of Monroe would like to thank you for the opportunity to comment on the Draft
NPDES Permit for our Wastewater Treatment Plant, permit number NC0024333. We have
reviewed the draft permit and would like to point out a few minor points for your consideration:
• Limits pages PART I A. (1.) and A. (2.): The limits pages show cyanide has a limit for
monthly average and daily maximum. We believe this was an over -site and should reflect the
limits for monthly average and weekly average.
• NPDES Permit Standard Conditions section; pages 3, 9, 12 and 18 of 18: Should Division of
Water Quality be changed to Division of Water Resources?
Thanks again for the opportunity to comment on this important permit. If you need any
additional information please contact Mr. Kyle Ketchum, WWTP Superintendent at (704) 282-
4612 or me at [phone].
Sincerely,
glemiell ea/lath

Background
The City of Monroe's Wastewater Treatment Plant (Monroe WWTP) is a Class IV facility with a
phased permit allowing flows of 10.4 MGD and 12.5 MGD. The plant treats wastewater from
residential, commercial and industrial sources. Monroe has a Long Term Monitoring Plan
(LTMP) with the Division of Water Quality's Pretreatment Unit that it will continue to
implement in the coming permit term.
On July 19, 2004 the City was also issued an Authorization to Operate granting the Monroe
WWTP a re -rating from 9.0 MGD to 10.4 MGD. As the City lost some industrial users it
decided not to expand the capacity to 12.5 MGD as originally scheduled. However, the City
requested that the phased permit allowing flows of 10.4 MGD and 12.5 MGD be maintained
even though the current economy has slowed and the City does not plan to expand at this
time.
Instream Monitoring, Verification of Existing Conditions and DMR Data Review
This facility discharges to Richardson Creek in subbasin 03-07-14 of the Yadkin -Pee Dee River
Basin. The creek skirts the urbanized areas around Monroe. Richardson Creek is classified C
waters at the point of discharge and is listed as impaired for biological integrity and copper
standard violations on the 2012-303(d) list. The City is required to sample upstream and
downstream of the discharge for dissolved oxygen, temperature, fecal coliform, and
conductivity, but is waived from this requirement as long as the City remains a member of the
Yadkin Pee Dee monitoring Coalition which performs monitoring upstream (station Q8800000)
and downstream (station Q8820000) of the discharge for these parameters.
Little difference and no trends were noted between upstream and downstream values for
dissolved oxygen, temperature, turbidity and fecal coliform (please see attached). No depressed
dissolved oxygen values were noted upstream or downstream of the discharge. There were
noticeable differences between the upstream and downstream conductivity, nitrates/nitrites,
and TP values.

Compliance History
A review of correspondence files for the last five years revealed no recurring problems or major
deficiencies in Monroe's compliance history except for several violations of the cyanide limit,
which only occurred during 2010.
WET Test Results
During the last 5 years the City of Monroe has consistently passed the Whole Effluent Toxicity
(WET) test with 1 exception. The failure was followed by two consecutive passing toxicity tests.
Reasonable Potential Analysis (RPA)
The Reasonable Potential Analysis (RPA) was conducted for Copper, Cyanide, Fluoride, Silver,
Zinc, and Selenium (please see attached. The limits for Copper, Silver, and Zinc are not
required because these parameters have Action Level Standards and the facility is consistently
passing WET test.
The Division also considered data for other parameters of concern in the EPA Form 2C that
facility submitted for the renewal. The majority of the parameters were not detected in the
discharge. The Division reviewed the following parameters that were detected in the discharge
and have applicable state standards or EPA criteria for Class C: Arsenic, Mercury, and Nickel.
All of these parameters were well below the state standards/ EPA criteria.
Mercury Evaluation
The mercury evaluation was conducted in accordance with the Permitting Guidelines for
Statewide Mercury TMDL.
WQBEL allowable concentration for this facility is 12 ng/L. The average mercury concentration
in the discharge was 0.47 ng/L and the highest mercury concentration was 1.22 ng/L. Based
on the Permitting Guidelines for Statewide Mercury TMDL, the facility will be required to
continue mercury monitoring through PPA.
Permit Limits
• BOD limits in the permit are based on the water quality model.
• TSS limits in the permit are based on the requirements of the 40 CFR 133.102.
• Ammonia limits in the permit are based on the water quality model. The Division uses
ammonia criteria that were developed by EPA: 1 mg/ L - summer; 1.8 mg/ L — winter.
• TRC limit in the permit is based on the North Carolina water quality standards [15A
NCAC 2B .0200].
• pH limit in the 'permit is based on the North Carolina water quality standards [15A
NCAC 2B .0200].
• Fecal Coliforms limits in the permit are based on the North Carolina water quality
standards [15A NCAC 2B .0200].
• Cyanide limits in the permit are based on the results of the Reasonable Potential
Analysis
Proposed Permit Changes
• The weekly average limit for cyanide has been changed to monthly average in
accordance with the 40 CFR 122.45 (d)(2), which requires monthly average and daily
maximum limits in the permit.
• The effluent was evaluated in accordance with the Monitoring Frequency Reduction Review
Guidance. The facility has met the requirements of the guidance for BOD, TSS, ammonia

nitrogen, and fecal coliforms. Therefore, monitoring for these parameters will be reduced from
daily to 2/Week.
• 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 the permit. [See Special Condition A. (5.)]

Sludge Management Plan
NPDES NC0024333
Discharge 001
Solids treatment and disposal facilities consist of five aerobic digesters, one
liquid loading station, one two meter belt press, self contained concrete cake
storage pad and all necessary equipment to load, transport and land apply
liquid and/or dewatered cake on privately owned farmland. The aerobic
digesters are used in a series for thickening, stabilization and storage of
sludge. The waste activated sludge is first pumped from secondary clarifiers
via RAS pumps to two 250,000 gallon digesters where it is thickened and
aerated until it reaches about three percent. Thickened solids are then
pumped into a 1,150,000 gallon digester where it is constantly aerated. The
solids are then pumped into a 500,000 gallon aerobic digester and then into a
3,000,000 fine bubble diffused aerated digester where they are held and
aerated until volatile solids reduction is achieved. From this digester the
solids can be loaded onto tanker trucks, hauled and land applied as a liquid
or fed into a two meter belt press, caked, and either hauled directly to the
fields or stored on a concrete storage pad until being hauled and applied.
The City of Monroe currently holds land application permit number
WQ0001346. We currently meet Class B residual requirements and apply no
more than 3,244 dry tons per year.
