Subject: Electronic Reporting Requirement of Discharge Monitoring Data
Compliance Period Extended to 270 Days
Dear NPDES Pe . ittee:
John P. Skvarla, 111
Secretary
The purpose of this letter is to notify you of the change to the permit condition regarding
Electronic Reporting of Discharge Monitoring Reports. The Division of Water Resources has
imposed a new permit condition into new and re -issued NPDES permits requiring pernuttees to
begin using the Division's Electronic Discharge Monitoring Report (eDMR) internet application.
NPDES permits recently issued contained a compliance period of 90 days to meet this
requirement. This compliance period has been subsequently changed and extended to 270 days.
Beginning no later than 270 days from your NPDES permit's effective date, you shall begin
reporting discharge monitoring data electronically using the Division's eDMR internet
application.
This letter serves to a end your NPDES pernxit as noted above. Please attach this letter to your
NPDES permit
-it.
If you have any questions regarding the contents above, please contact Vanessa Manuel at
919/807-6392 or via email at Vanessa.Manuel(incdenr.gov.

A. (2.) 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, quarterlq monitoring using test procedures
outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised
December 2010, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised- December 2010) or subsequent versions. The tests will be
performed during the months of January, April, July and October. These months signify the
first month of each three month toxicity testing quarter assigned to the facility. Effluent
sampling for this testing must be obtained during representative effluent discharge and 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 -December 2010) 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, using the
parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally,
DWR Form AT-3 (original) is to be sent to the following address:

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 peiinittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month. Assessment of toxicity compliance is
based on the toxicity testing quarter, which is the three month time interval that begins on the
first day of the month in which toxicity testing is required by this permit and continues until the
final day of the third month.

Permit No. NC0036277
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. (4) MERCURY MINIMIZATION PLAN
The permittee will develop and implement a mercury minimization plan during the term of this
permit, The MMP shall be developed 180 days from the effective day of the permit, and shall be
available for inspection on -site. A sample MMP was developed through a stakeholder review
process and has been placed on the Division website for guidance
(http:/ /portal.ncdenr.org/web/wq/swp/psinpdes, under Mercury Minimization Plan). 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.
A. (5) 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.
NOTE: This special condition supplements or supersedes the following sections within Part II of
this permit (Standard Conditions for NPDES Permits):
Section B. Signatory Requirements
(11.)
Section D. (2.) Reporting
Section D. (6.) Records Retention

Beginning no later than 90 days from the effective date of this permit, the permittee shall
begin reporting discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each
month and submitted electronically using eDMR. The eDMR system allows permitted
facilities to enter monitoring data and submit DMRs electronically using the internet. Until
such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic
Reporting Regulation (CROMERR), permittees will be required to submit all discharge
monitoring data to the state electronically using eDMR and will be required to complete the
eDMR submission by printing, signing, and submitting one signed original and a copy of the
computer printed eDMR to the following address:
NC DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
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.

Permit No. NC0036277
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/wo/admin/bo /ipu/edrnr
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.) (d)l
All eDMRs submitted to the peiinit 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,

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 Pennittee'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 0211
.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 Pemiittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatrnent 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 I 5A 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
M903(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-dischargc 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 thc 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 Perrnittee 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.

SUMMARY
The Charlotte Mecklenburg Utility Department (CMUD) operates the McDowell Creek WWTP
with a current permitted flow of 12.0 MGD. The treated domestic wastewaters are discharged to
McDowell Creek in the Catawba River Basin. CMUD submitted an application for renewal on
July 5, 2013. The permit expires on December 31, 2013.
The treatment system consists of: mechanical bar screens, grit removal, five primary clarifiers,
two trains activated sludge using three stage biological nutrient removal, two trains activated
sludge using five stage biological nutrient removal, four final clarifiers, denitrifying filter, UV
disinfection, membrane filtration, sludge thickening, and sludge dewatering.
CMUD has a full pretreatment program through the Division of Water Quality's PERCS Unit for
all five municipalities it operates. McDowell Creek WWTP currently has no industrial users.
RECEIVING STREAM
This facility discharges to McDowell Creek in the Catawba River Basin, classified WS-IV CA
waters. The discharge is 0.5 miles upstream of Mountain Island Lake. McDowell Creek and
Mountain Island Lake are not listed in the 2012 NC 303(d) list.
DMR DATA REVIEW AND VEFIFICATION OF EXISTING CONDITIONS

Data for CBOD, TSS, ammonia and fecal coliform was reviewed to determine compliance with
the 2012 Guidance Regarding the Reduction of Monitoring Frequencies. The facility meets all
the criteria specified in the guidance. Monitoring frequency for the above mentioned
parameters will be reduced to 2/week. See attached Reduction in Frequency Evaluation.
Reasonable Potential Analysis
A reasonable potential analysis was performed for copper and zinc. Both present reasonable
potential to exceed the standards. Since these parameters are action level standards no limits
are proposed. Monitoring will be required on a quarterly basis. See attached RPA results.
Mercury Evaluation
A mercury evaluation was conducted in accordance with the Permitting Guidance developed for
the implementation of the statewide Mercury TMDL to determine the need for a limit and
Mercury Minimization Plan (MMP). Based on dilution the water quality based effluent limitation
(WQBEL) for mercury is 13.2 ng/1. The technology based effluent limit (TBEL) is 47 ng/1. The
facility had detections above 1 ng/1 over the past five years, therefore a Mercury Minimization
Plan will be required in the permit but no limit will be implemented. A condition will be added
to the permit describing the requirements for the MMP.

B.3. Process Flow Diagram or Schematic
McDowell Creek WWTP is currently designed to treat 12.0 million gallons per day
(mgd) of wastewater. The attached schematics (SC-1, -2, -3) show the process flow
through the facility. A full summary of the process flow is included on the following
page.

Charlotte -Mecklenburg Utilities

NPDES # NC0036277
Process Flow Schematics
12-mgd treatment description
Preliminary treatment:
Wastewater enters the plant through a 36-inch gravity sewer line and splits between
two manholes. Flow then enters the headworks and influent pumping station through two
48-inch gravity sewer lines. Flow entering the head works separates into three screening
channels each sized for 30.0 mgd capacity and passes through mechanical bar screens.
Screenings are compacted and conveyed to a dumpster loading area common with the grit
dumpsters.
Primary treatment:
Following preliminary treatment, the wastewater splits between distribution boxes
(DB), DB-1 and DB-16 and is distributed to the five primary clarifiers (PC-1 through PC-
5). After primary treatment in the clarifiers, a part of the wastewater from PC-1 and PC-2
is directed through DB-4. It continues through DB-4a to combine with wastewater from
PC-3, 4 and 5 in DB-4a and further to DB-5 where it is combined with Return Activated
Sludge (RAS).
Secondary treatment:
The combined flow from PC-1, 2 and 3 through DB-10 is split equally between
biological treatment trains 1 and 2 where it goes through an anaerobic zone, anoxic/oxic
zone and aeration zone with internal recycle. Flow from PC-4 and PC-5 go through a rate
control structure before entering the newly constructed 5-stage BNR basins (BTB-3 and
4) designed for nitrogen and phosphors removal.
Following the aeration basin, flow from anoxic/oxic basins 1 and 2 is combined in
DB-9 and split to final clarifiers (FC) FC-1 and FC-2. Flow from BTB-3 is sent to FC-3
and from BTB-4 is sent to FC-4.
Tertiary treatment:
Combined secondary effluent from all the final clarifiers is sent to effluent filter
structure (EF) EF-1 and EF-2 for filtration and UV disinfection or 3.0 mgd is sent to
microfiltration units. Filtered effluent from the microfiltration system and the effluent
filter structures will be combined and sent to the cascade aeration structure where
aeration takes place. The cascade aeration structure will discharge through a 48" line into
McDowell Creek.

Inflow and Infiltration (I&I) Reduction Practices
Charlotte -Mecklenburg Utility Department (CMUD) has maintained an established evaluation
and rehabilitation program since the early 1990's. The purpose of this program is to restore
and preserve hydraulic capacity, structural integrity, and to reduce corrective maintenance
costs by addressing issues that cause SSOs. This includes maintaining and implementing an on-
going I/1 reduction plan.
Multiple construction contracts are continually in place to address these issues. Through
comprehensive SSES efforts, including manhole inspections, smoke testing, CCTV, flow
monitoring, etc., areas are identified for rehabilitation and work orders assigned to a
contractor. The work may include manhole rehabilitation, point repairs, pipe lining and pipe
replacement.
Since July 2003, CMUDs' Rehabilitation Team has inspected 500 manholes, smoke tested
27,000 ft. of pipe, and performed CCTV inspection on 15,000 ft. of pipe, resulting in the
following; 156 manholes rehabbed/repaired, 68 inflow dishes installed and 7,400 ft. of pipe
rehabbed/replaced throughout the collection system. This does not include similar work
performed by CMUDs' Field Operation Division. CMUD also implemented a chemical root
control program in March 2005 and we continue to maintain and expand that program.
CMUD uses flow monitoring extensively to support engineering analyses, to prioritize sewer
improvements, and to evaluate capacity issues and I/1 loadings in the major trunk lines in the
system. We currently have 52 permanent flow meters installed throughout the service area (3
permanent meters in the McDowell Creek basin) and utilizes temporary flow metering on an as -
needed basis.

Re: Irwin Creek Wt TP McDowell Creek WWTP, Whole Effluent Toxicity Violations for
samples collected on January 10th and 12th, 2012.
Dear Sir or Madam:
On January 10th and 12th, 2012, Irwin Creek WWTP (NC0024945) and McDowell Creek WVi
(NC0036277) collected Whole Effluent Toxicity (WET) samples as required by their NPDES
Permits.
The samples were analyzed by Meritech Labs, and both facilities failed with the multi -dilution
samples at low levels. The Irwin Creek WWTP failed at <41.5& and the McDowell Creek
WWTP failed at 55.1%. Irwin Creek has not failed a WET test for greater than five (5) years,
and McDowell Creek has not failed a WET test greater than 10 years. It seems very unusual that
both facilities would have a significant failure at the same time. Both facilities have significantly
different wastestreams and treatment processes.
When we received notification of the WET failures, we reviewed the plant data and
circumstances at the time the samples were collected. Following is the information we found:
At Creek WWTP:
A. Effluent sample results for this week were non -detect for both cBOD and TSS, with
only one detection of ammonia on 1/11/12 at 0.1 mg/1.
B. Effluent Metals were collected on 1/11 and 1/12/12 with all results well within
normal effluent concentrations of metals. We have conducted many WET tests with
metals at these concentrations without any impact on the WET test.
C. A PPA sample was collected on the effluent on 1/11/12. No organics were detected
on the effluent.
D. With everything being well within a normal to low discharge concentration, when we
have passed WET testing at higher concentrations of metals and other pollutants in
the discharge, it is difficult to believe this test failed so significantly.
At McDowell Creek WWTP:
A. Effluent sample results for this week were all below detection for cBOD, TSS and
ammonia.

B. This is a predominantly domestic plant without any Significant Industrial User (SIU)
discharge and a relatively small commercial discharge percentage with tertiary
treatment from nutrients and fine filtration.
C. This facility has not had ANY violations in nine (9) years. The last violations were
for flow and even with the flow excursions, all other pollutant limits were in
compliance with permit limits.
D. ' At this time, there is a significant amount of ceriodaphnia dubia (water fleas) living
on the final clarifiers at the plants. The water fleas are thriving and reproducing. How
is it possible to fail the WET test at 55%, when there is a thriving colony living in the
wastewater at the plant?
After the failure notices were received, we scheduled the plants to sample in February and March
as required. These samples were scheduled on the same dates as two of our other plants were
scheduled to sample. The following week, Meritech Labs called CMUD to ask us to re -schedule
the sampling dates due to an incubator being out of service and did not have the capacity — with
this incubator out of service — to conduct the WET test. We find it interesting that the lab was
having incubator problems close to the time the CMUD plants had the unexplainable WET test
failures.
While we are marking the DMR's non -compliant for, the month of January, 2012, we strongly
object and do not believe this is a true indication that the wastewater discharge from these
facilities had any adverse impact on the water quality. We will be collecting multi -dilution
samples for the next three (3) months as required by the NPDES Permits.
If you have any questions about our objections to this non-compliance, or any other statement in
this report, please give me a call.

MSD = Minimum Significant Difference
PMSD = Percent Minimum Significant Difference
PMSD is a measure of test precision. The PMSD is the minimum percent difference between the control and treatment that can be declared
statistically significant in a whole effluent toxicity test.
Lower PMSD bound detennined by USEPA ()0th percentile) = 13%.
Upper PMSD bound determined by USEPA (90th pereentile) = 47%.
Lower and upper PMSD bounds were determined from the 10th and 90th percentile, respectively, of PMSD data from EPA's WET
lnterlaboratory Variability Study (USEPA, 2001a; USEPA, 2001b).

MSD = Minimum Significant Difference
PMSD = Percent Minimum Significant Difference
PMSD is a measure of test precision. The P
statistically significant in a whole effluent to
D is the in

percent difference between the control and treatment that can be declared
Lower PMSD bound determined by USEPA (10th percentile) = 13%,
Upper PMSD bound determined by USEPA (90th percentile) = 47%.
Lower and upper PMSD bounds were determined from the loth and 90th percentile, respectively, of PMSD data from EPA's WET
Interlaboratory Variability Study (USEPA, 2001a; USEPA, 2001b).

MSD = Minimum Significant Difference
PMSD = Percent Minimum Significant Difference
PMSD is a measure of test precision. The PMSD is the minimum percent difference between the control and treatment that can be declared
statistically significant in a whole effluent toxicity test.
Lower PMSD bound determined by USEPA (10th percentile) = 13%.
Upper PMSD bound determined by USEPA (90th percentile) = 47%.
Lower and upper PMSD bounds were determined from the 10th and 90th percentile, respectively, of PMSD data from EPA's WET
Interlaboratory Variability Study (USEPA, 2001a; USEPA, 2001b);
