Subject: Draft NPDES Permit Renewal
Permit NCO023973
M'Kean Maffitt (Southside) WWTP
New Hanover County
Class 4, SIC Code 4952
Dear Mr. Flechtner:
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility Please review this
draft carefully to ensure thorough understanding of the requirements and conditions it contains. There are
several changes from the existing permit, including the following:
The receiving stream, the Cape Fear River, is designated a Primary Nursery Area (PNA) in 15A
NCAC 03R .0103(19)(a), which merits High Quality Water (HQW) status with specific water
quality standards for new and expanded discharges per 15A NCAC 02B .0224. Your facility's
current permitted flow of 12 MGD predates the effective date of the PNA designation, so limits are
not affected. However, the HQW-related limits do apply to the expansion phases at 16, 20 and 24
MGD. Limits include BODS = 5 mg/L, TSS = 10 mg/L, NH3-N = 2 mg/L and DO = 6 mg/L; and a
safety factor of % normal standard is included for individual toxics. Coincidentally, equivalent
BOD and DO limits are already in the current permit for the expanded phases, as are lower NH3-N
limits. Therefore, TSS limits of 10 mg/L monthly average and 15 mg/L weekly average have been
added to the permit at 16, 20 and 24 MGD expansion phases.
The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Committee (EMC) on November 13, 2014. The US EPA subsequently
approved the WQS revisions on April 6, 2016 with some exceptions. The NC Division of Water
Resources NPDES Permitting Unit is required to implement the new dissolved metal standards in
all permits public noticed after April 6, 2016. The new standards for most metals include acute
standards. The saltwater standards for several metals are expressed as the dissolved form of the
metals.

Based on the new WQS approved on April 6, 2016 for dissolved metals, a monthly average limit
of 3.7 gg/L and a daily maximum limit of 5.8 gg/L for Total Copper have been added to the permit
at 12 MGD, and samples shall be taken monthly. Results of a reasonable potential analysis on
submitted data at 12 MGD flow indicated a reasonable potential to exceed the instream WQS. To
allow time and actions toward meeting the new Total Copper limits, a 4 -year compliance schedule
has been added to the permit with annual milestones. [See Special Condition A. (9.).]
Based on the PNA designation of the receiving stream, a monthly average limit of 1.8 gg/L and a
daily maximum limit of 2.9 gg/L for Total Copper have been added to the permit at 16, 20 and 24
MGD phases, and samples shall be taken monthly. Results of a reasonable potential analysis on
submitted data at all expanded flow scenarios indicated a reasonable potential to exceed the
instream WQS.
Effluent mercury data was reviewed from June 2014 through September 2017. The Permittee tested
effluent for Total Mercury using EPA test Method 1631E throughout this period. In accordance
with the 2012 Mercury TMDL NPDES Guidance, the Permittee needs to show annual mean
effluent concentrations below the Water Quality Based Effluent Limitation (WQBEL) of 25.0 ng/L
and no exceedance of the Technology Based Effluent Limitation (TBEL) of 47 ng/L A review of
the data at all flow scenarios showed that the annual averages were below the WQBEL and all data
were below the TBEL; therefore, no mercury limitation is required.
Twenty-two (22) out of 23 low-level effluent mercury samples collected were over 1 ng/L. As a
result, a Mercury Minimization Plan (MMP) requirement has been added to this permit renewal.
See Section A (8 ) Please note that the Permittee shall develop and implement a MMP during this
permit term. The MMP shall be developed within 180 days of the NPDES Permit Effective Date,
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/ps/npdes, under Model Mercury Minimization Plan).
Results of a Reasonable Potential Analysis of effluent sampling data for Total Nickel showed no
reasonable potential to violate NC water quality standards instream, but the maximum predicted
value was more than half of the allowable concentration at 12 MGD. A reasonable potential was
detected at the higher tiered flows, but this was based on several non -detects that were above the
allowable discharge concentration of 4.2 gg/L plus two detects that were below this value.
Quarterly monitoring for Total Nickel shall be maintained as part of the Permrttee's Pretreatment
Long Term Monitoring Program (LTMP), and shall be reported via DMRs.
Review of submitted effluent data found 14 non -detects of Total Nickel at < 10 gg/L and two
detections: at 1.6 and 1.8 gg/L. In accordance with 15A NCAC 2B .0500, all test procedures must
produce detection and reporting levels that are below the permit discharge requirements and all
data generated must be reported to the approved detection level or lower reporting level of the
procedure. Currently, DWR's laboratory identifies the Practical Quantitation Limit (PQL) for Total
Nickel at < 2 0 gg/L. The allowable discharge concentration for your facility is 8.3 gg/L Total
Nickel at 12 MGD, and 4.2 gg/L Total Nickel at 16, 20 and 24 MGD flow rates. Therefore, effluent
sampling for Total Nickel as monitored via the Permittee's LTMP and effluent scans, shall be
analyzed down to the lower reporting level of the procedure, which is < 2.0 gg/L, for all permitted
flow rates. Additional monitoring and limits may be added in the next permit renewal if
compliance is not demonstrated.

• Results of a Reasonable Potential Analysis of effluent sampling data for Total Phenolic Compounds
showed no reasonable potential to violate NC water quality standards mstream, but the maximum
predicted value was more than half of the allowable concentration at 16, 20 and 24 flow rates.
Quarterly monitoring for Total Phenolic Compounds has been added to the permit at the three
expansion flows.
Review of submitted effluent data found 14 non -detects of Total Silver at < 2 µg2. In accordance
with 15A NCAC 2B .0500, all test procedures must produce detection and reporting levels that are
below the permit discharge requirements and all data generated must be reported to the approved
detection level or lower reporting level of the procedure. Currently, DWR's laboratory identifies
the PQL for Total Silver at < 1.0 µg2 The allowable discharge concentration for your facility is
0.10 µg/L Total Silver at 12 MGD, and 0 05 µg/L Total Silver at 16, 20 and 24 MGD. Therefore,
the best your facility can do is sample for Total Silver down to the lower reporting level of the
procedure, which is < 1.0 µg/L. The Division recommends that the Permittee improves and
implements "clean" sampling techniques. Quarterly monitoring for Total Silver has been added to
the permit, to verify that silver concentrations are consistently less than the allowable
concentrations. If they are not, then increased monitoring or limits will be added to the permit
during the next renewal.
• Results of a Reasonable Potential Analysis of effluent sampling data for Total Zinc showed no
reasonable potential to violate NC water quality standards mstream, but the maximum predicted
value was more than half of the allowable concentration at 16, 20 and 24 MGD flow rates. Quarterly
monitoring for Total Zinc shall be maintained as part of the Permittee's Pretreatment Long Term
Monitoring Program (LTMP), and shall be reported via DMRs.
• Effluent Pollutant Scans shall be sampled in three years within the permit term per 40 CFR 122
The years Effluent Pollutant Scans shall be sampled are 2019, 2020 and 2021. [See Special
Condition A. (6.).]
• The Modeling Requirement [Special Condition A. (7.)] has been revised to include submission of
a Dilution Study Plan to the Division for review and approval. The condition has also been revised
to recognize that a dilution study may be performed at 12 MGD or at a minimum prior to expansion.
As a result, revision to the dilution study will be necessary to reflect any changes to the outfall
structure. Please review it carefully.
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports. The final NPDES Electronic Reporting Rule was adopted and became effective
on December 21, 2015. The requirement to continue reporting discharge monitoring data
electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) mternet
application has been added to your final NPDES permit [See Special Condition A. (12.) —
Electronic Reporting of Monitoring Reports.].

Please note that the receiving stream is listed as impaired for Copper and Dissolved Oxygen on the North
Carolina 2014 303(d) Impaired Waters List. Addressing impaired waters is a high priority with the Division,
and instream data will continue to be evaluated. If there is noncompliance with permitted effluent limits
and stream impairment can be attributed to your facility, then mitigative measures may be required.
Concurrent with this notification the Division is publishing a notice in a newspaper having circulation in
the general New Hanover County area, soliciting public comments on this draft permit. Please provide any
written comments you may have to the following: NCDEQ/DWR, NPDES Permitting Branch, 1617 Mail

b) Once the model is reviewed and approved by the Division, the dilution factor determined by the model will
be used to establish limits for toxicants and Whole Effluent Toxicity testing.
2. Dilution Study for expanded flows:
a) The model used to determine dilution for Outfall 001 at 12 MGD shall be updated to evaluate dilution for
the proposed expanded flows (16 MGD, 20 MGD, and 24 MGD). However, if a model was not developed
for 12 MGD, then the Permittee shall sub imt a Dilution Study Plan for 16 MGD to the Division for review
and approval prior to expansion. Guidelines detailed in Subsection A. (7.)(1.) above, shall be followed for
the 16 MGD dilution study and model.
The Permittee shall submit a revised model providing additional information regarding end -of -pipe dilution
at the same time as the' ATC application is submitted. The model shall address dilution at the approved
increased flow rate into the Cape Fear River at M'Kean Maffit WWTP's for the proposed discharge
configuration. The model report shall be submitted to the following address:
NC Division of Water Resources
NPDES Complex Permitting Branch
1617 Mail Service Center
Raleigh, NC 2699-1617
b) Once the model is reviewed and approved by the Division the dilution factor determined by the model will
be used to establish limits for toxicants and Whole Effluent Toxicity testing.
A. (8.) MERCURY MINIMIZATION PLAN (MMP) [G S. 143-215.1 (b)]
The Permittee shall develop and implement a Mercury Mmimization Plan (MMP) during this permit term The
MMP shall be developed within 180 days of the NPDES Permit Effective Date, 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://deq.nc.gov/about/divisions/water-resources/water-resources-
permits/wastewater-branch/npdes-wastewater-permits, under Model 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. Performance of the MMP will meet the requirements of
the TMDL (Total Maximum Daily Load) for mercury approved by USEPA on October 12, 2012, unless and until
a Waste Load Allocation specific to this facility is developed and this NPDES permit is amended to require further
actions to address the Waste Load Allocation.

Upon approval of the Corrective Action Plan by the Division, the report and actions become an enforceable part
of this permit Any modifications to the schedule shall be requested to the Division at Jeast nmety (90) days before
the deadline. Modifications to the schedule in excess of four (4) mo the will be subject to public notice
A. (10.) HISTORICAL PERMIT LIMITS
The Division recognizes that,pnor to issuance of this permit; the M'Kean Maffitt (Southside) WWTP was
permitted to discharge with/secondary limits of 25.0 mg/L CB0135, 30.0 mg/L,TSS, and no limit for NH3-N. At
the permitted flow of 12.0 MGD, these limits translate approxunately to mass loads of 457 tons per year (tpy)
BODS, 548 tpy TSS, and 365 tpy NH3-N,(assuming 20 mg/L). The mass loads described in this paragraph will be
one factor the Division considers when developing future wasteload allocations resulting from the TMDL process
or when considering future expansion requests for,the M'Kean Maffitt WWTP.
A. (11.) ANTI -BACKSLIDING
The BODS and NH3-N limits in this permit may be replaced with less stringent limits without violating state and
Federal anti -backsliding provisions if
3
1. Material and substantial alterations or additions to the permitted facility occurred after permit issuance
that justifies less stringentlimits;
2. Events occurred beyond the Permittee's control for which there is no reasonably available remedy;
3. Permittee has properly installed and operated required treatment equipment that cannot achieve permit
limits; or
4. New information (other than revised regulations, guidance, or test methods) is available that justifies less
stringent limits;
and provided that the Division deems such modification appropriate and consistent with applicable laws and
regulations.

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. See "How to Request
a Waiver from Electronic Reporting" section below.
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.
Starting on December 21, 2020, the Permittee must electronically report the following compliance monitoring
data and reports, when applicable:
Sewer Overflow/Bypass Event Reports;

3. How to Request a Waiver from Electronic Reporting
The Permittee may seek a temporary electronic reporting waiver from the Division. To obtain an electronic
reporting waiver, a Permittee must first submit an electronic reporting waiver request to the Division.
Requests for temporary electronic reporting waivers 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
submitting monitoring data and reports. The duration of a temporary waiver shall not exceed 5 years and shall
thereupon expire. At such time, monitoring data and reports shall be submitted electronically to the Division
unless the Permittee re=applies for and is granted a new temporary electronic reporting waiver by the Division
Approved electronic reporting waivers are not transferrable. Only Permittees with an approved reporting
waiver request may submit monitoring data and reports on paper to the Division for the period that the
approved reporting waiver request is effective.
