Subject: Issuance of NPDES Permit NC0024333
Monroe VVWTP
Union County
Dear Mr. Colbath:
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 17, 2007 (or as subsequently amended.)
This final permit includes the following changes from the draft permit sent to you on September 9, 2009.
> As requested, corrections were made regarding the dates and Permit Cover Sheet changes cited in your
letter dated September 25, 2009.
> Fluoride and selenium do not show a reasonable potential for an instream violation. Fluoride and
selenium NPDES limits and monitoring requirements are being removed from the permit. Both
parameters will remain in the facility's Pretreatment - Long Term Monitoring Program and will be
monitored quarterly.
The remaining changes in the final permit are the same changes recognized in the draft permit
which differed from your current permit as follows:
> Footnote Number 4 was amended under Section A (1.) to include the following
statement: TRC limit and monitoring requirement only apply if chlorine is used for
disinfection. The Permittee shall report all effluent TRC values reported by a NC -
certified laboratory [including field -certified]. Effluent values below 50 µg/L will be
treated as zero for compliance purposes.
> The wording in Section A. (3.) has been changed and the following paragraph added: 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 Discharge Monitoring Report and all AT Forms submitted.

Richardson Creek is listed as an impaired stream on North Carolina's 303 (d) list. Currently, the stream does
not meet all water quality standards. If the limitations in the current permits for facilities discharging to
Richardson Creek do not result in improved water quality, removal of discharges to Richardson Creek may be
necessary for the health of the stream.
Although the Division believes multiple sources of wastewater cause degradation to Richardson Creek, we
will continue to monitor compliance at your facility. If noncompliance with your permit's effluent limits is
shown to be a direct cause of stream degradation, the Division will recommend removal of your facility's
discharge.
Part III of your permit requires you to "continually evaluate all wastewater disposal alternatives and pursue
the most environmentally sound alternative of the reasonably cost effective alternatives" to surface water
discharge. Such an evaluation may help you find an alternative to surface water discharge that is more
appropriate for your facility.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable
to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt
of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North
Carolina General Statutes, and filed with the office of Administrative Hearings, 6714 Mail Service Center,
Raleigh, North Carolina 27699-6714. Unless such a demand is made, this permit shall be final and binding.
Please take notice that this permit is not transferable. The Division may require modification revocation and
reissuance of the permit. This permit does not affect the legal requirements to obtain other permits which may be
required by the Division of Water Quality or permits required by the Division of Land Resources, Coastal Area
Management Act, or any other Federal or Local governmental permits may be required.
If you have questions concerning this permit, please contact Julie Grzyb by e-mail
([e-mail]) or phone at [phone].
Sincerely,

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, DWQ Form AT-1 (original) is sent to the below address. If reporting Chronic Value
results using the parameter code THP3B, DWQ Form AT-3 (original) is to be sent to the following address:
'Attention: NC DENR / Division of Water Quality
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 Quality indicate potential impacts to the receiving stream, this permit may 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.

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.
The current permit was issued on July 19, 2004 and expired on January 31, 2009. The permit has been
administratively extended until a new permit is issued. 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.
The plant has limits of 7.3/1 (BOD5/NH3, which is equivalent to 5/2 limits) at 10.4 MGD and 5/1
(BOD5/NH3) at 12.5 MGD. Essentially, the facility has tertiary limits at both flows. Note that total
residual chlorine is limited as a weekly average and daily average. The weekly average is based on the
chronic standard for chlorine, while the daily average is based on the acute cap. The City requested this
in 1998 and it remains in the drafted permit.
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 biological integrity on the 2006-303(d) list and impaired biological
integrity and impaired for turbidity on the 2008-303(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 and downstream of the discharge for these parameters

Page 2 s
and more. A spread sheet of the data showing Coalition sampling results from January 2006 through
January 2008 is attached to this fact sheet.
Little difference and no trends were noted between upstream and downstream values for dissolved
oxygen, temperature, turbidity and fecal coliform. No depressed dissolved oxygen values were noted
upstream or downstream of the discharge and all DO values were greater than 6 mg/1 during 2006, 2007
and 2008. There were noticeable differences between the upstream and downstream conductivity, TKN
and TP values.
Effluent DMR data from May 2006 through May 2009 were reviewed. Data for conventional parameters
are summarized in Table 1. In addition to the parameters listed in Table 1, the Permittee is also required
to monitor for total nitrogen, total phosphorus, ammonia nitrogen, total residual chlorine and oil &
grease. This data is summarized in Table 2. For all parameters listed in both Tables the Permittee has
complied with permit limitations during the specified timeframe.

Correspondence files and Compliance History
A review of correspondence files for the 2007- June 2009 period revealed no recurring problems or major
deficiencies in Monroe's compliance history. The September 2008 Compliance Evaluation Inspection
noted that the wastewater treatment plant facilities appeared to be in good condition during the site
investigation.
A review of the historical Pretreatment Significant Noncompliance (SNC) Report showed two violations
during 2006 through 2007. Bloomsburg Mills Inc showed one incidence of significant noncompliance
with cyanide during the last half of 2007 and Charlotte Pipe & Foundry Company showed one incidence
of significant noncompliance with copper during the first half of 2006. Neither industrial pretreatment
violation resulted in an effluent violation at the Monroe WWTP.
In March 2008, the Permittee received a Notice of Violation for exceeding the weekly average and daily
maximum limits for Cyanide. The two violations carried an associated civil penalty assessment of
$583.89. Plant personnel believe the violations were due to laboratory errors but no evidence could be
provided to substantiate this claim.

WET Test Results
Out of the last 18 Whole Effluent Toxicity tests performed, the City of Monroe has passed 16 and failed
two. One failure occurred in September 2005 and the other in December 2008. Both failures were
followed by two consecutive passing toxicity tests.
PERMITTING STRATEGY
Reasonable Potential Analysis (RPA)
Reasonable potential analyses were performed at each of the permitted flows, 10.4 MGD and 12.5 MGD,
using DMR data from June 2006 through June 2009.
Table 3 identifies the parameters the City monitors under its current NPDES permit, the parameters
which currently have limitations, the parameters monitored under the Pretreatment - Long Term
Monitoring Plan (LTMP), and the parameters for which an RPA analysis were performed. Monroe's
WWTP has an instream wastewater concentration (IWC) of 97% at 10.4 MGD and 98% at 12.5 MGD.
The results of the reasonable potential analysis for both flows were identical.

RPA results at 10.4 MGD
Results suggest no reasonable potential for the facility to discharge arsenic, cadmium, chromium,
fluoride, mercury, nickel, selenium, and phenols. It is recommended that the limits for fluoride and
selenium be removed and monitoring be reduced from weekly to 2/month. Monitoring for arsenic,
cadmium, chromium, mercury, nickel, and phenols will continue through the Pretreatment - Long Term
Monitoring Plan (LTMP) as well as the additional toxicants listed in Table 3.
Effluent from the facility did demonstrate reasonable potential to exceed water quality criteria for copper,
cyanide, silver, and zinc.
■ The existing limits and monitoring associated with cyanide will be carried over into this permit
term.
• The copper and zinc maximum predicted concentrations are above the allowable acute and
chronic standards exhibiting some reasonable potential for a violation. Since these are Action
Level standards and should be reviewed in conjunction with toxicity testing, it is recommended
that monitoring for copper and zinc remain in the NPDES permit at a measurement frequency of
2/Month.
• The maximum predicted concentration for silver is above the allowable acute and chronic
standards exhibiting some reasonable potential for a violation. Both the acute and chronic water
quality standards for silver are Action Level standards and a limit is not normally given for this
parameter. There was one significant excursion of silver on 7-2-08 at a concentration of 7.2 ug/l.
No limit is recommended for silver but monitoring should continue at 2/Month.
RPA Results at 12.5 MGD
The results of the reasonable potential analysis for 12.5 MGD were identical to those for 10.4 MGD.
PPA Data
Some volatile organics were above detection level on the permit application; however, all of them were
below the EPA human health criteria and will not be monitored or limited.
PROPOSED PERMIT CHANGES
Remove the fluoride limitation and reduce monitoring to 2/Month.
Remove the selenium limitation and reduce monitoring to 2/Month.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE
Draft Permit to Public Notice:
Permit Scheduled to Issue:
September 15, 2009 (est.)
November 2, 2009 (est.)
NPDES DIVISION CONTACT
If you have any questions on any of the above information or on the attached permit, please contact Julie
Grzyb at [phone].
ADDENDUM TO FACT SHEET:
It is recommended that the NPDES limits and monitoring requirements for fluoride and selenium be
removed from the permit. Monitoring for both parameters will continue through the Pretreatment - Long
Term Monitoring Plan (LTMP) and enough data will be available to perform a reasonable potential
analyses when the permit is up for renewal in 2014.

Dear Ms. Grzyb:
We have received the draft permit for the City of Monroe wastewater treatment plant
which holds Permit Number NC0024333 and have examined the changes from the current
permit and understand the conditions and requirements. We appreciate the removal of
limits for fluoride and selenium and also the reduction of monitoring. We offer the
following minor comments;
• On the cover page of the permit please note the year 2004 needs to be corrected.
• On the Supplement To Permit Cover Sheet under description of facilities please
change the first bulleted item to read "Two influent pump stations with a total of
six pumps." Change the tenth item to read "Five sand drying beds (inactive)."
Change the eleventh item to read "Filter press and bio-solids cake storage bed with
drainage system connected to facility headworks." Remove the last item as the
centrifuges have been removed from service and are no longer at the facility.
Should you require additional information please do not hesitate to call me at (704)-282-
4601 or Kim Hinson at [phone].
Respectful)

Jennifer- I received a hardcopy of the ER Resubmittal (dated 3/20/2009) to CG&L for
the City of Monroe Stewart's Creek Pump Station and Gravity Sewer Outfall. NPDES
offers no comments on this project, which focuses on 20-year flow projections to
assist with design of a pump station. NPDES will ultimately evaluate flow
projections for the entire WWTP service area, when the City comes in for a WWTP
expansion request under NC0024333.

POINT SOURCE BRANCH
The City of Monroe Wastewater Treatment Plant, currently discharging wastewater from
a location at 775 Treeway Drive in Monroe, North Carolina to receiving waters
designated as Richardson Creek in the Yadkin -Pee Dee River Basin in accordance with
NPDES Permit number NC0024333, which will expire on January 31, 2009, does hereby
submit an application for permit renewal. This request is being made in accordance with
Part II (B) (10) of the current discharge permit and 15A NCAC 2H.0105(e).
Since the submittal of the last permit application dated July 29, 2003 the treatment plant
requested and received a re -rating from 9 MGD to 10.4 MGD. This was based on plant
performance and a 4 MG equalization basin expansion. The two centrifuges used for
sludge thickening have been removed from service and replaced with a belt filter press.
All other plant processes remain as before.

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 which contains 3,160.7 acres of privately owned farmland. We
currently meet Class B residual requirements and land apply no more than
3,244 dry tons per year.
