Subject: Draft NPDES Permit NC0021971
Charlotte Terminal
Grade I Physical Chemical WPCS
Mecklenburg County

Dear Ms. Brown:

The Division has reviewed your request to renew the subject permit. Please review this draft carefully to
ensure a thorough understanding of the information, conditions, and requirements it contains.

The draft permit includes the following significant changes from the existing permit:
1. The facility classification Grade I Physical Chemical Water Pollution Control System (WPCS) was
added to the effluent page for Outfalls 009 & 010.
2. A monthly average limit of 30 mg/L was added for Total Suspend Solids (TSS).
3. The Oil & Grease (O&G) parameter code [00556] remains the same for submitting DMR/eDMR,
but uses test EPA method 1664 (SGT-HEM) with results in mg/L .
4. Since Gum Branch is not currently listed on the 2018 303(d) List as impaired for Turbidity, the
limit and footnote for this parameter has been removed.
5. Concurrent sampling for BTEX and Acute Toxicity is no longer required by the Division. The
footnote referring to this requirement was removed .
6. The acute toxicity monitoring Special Condition A. (3.) was updated to include guidance for
electronic submission of toxicity tests.
7. The electronic reporting permit Special Condition A. (5.) was updated to be consistent with the
finalization of federal requirements for electronic reporting.
8. The permit map was updated.

The NPDES standard conditions (Parts II, III, and IV) that are a part of the permit are not included in
this draft document (cover, map, and Part I). The conditions are the same as in your current permit
except that agency and division names have been updated. The latest version is available at
https://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF file.

A. (3.) FLOW MEASUREMENT RATIONAL [G.S. 143-215.1(b)]

The Rational Equation: Q=KuCIA, where:
Q = flow (peak flow rate (cfs or m3/sec) Ku = units conversation f actor = 1.008 for U.S. standard units (usually ignored
because it is so close to 1), or 0.278 for SI units
C = dimensionless runoff coefficient for the watershed, loosely defined as the ratio of runoff to rainfall I = intensity o f rainfall taken from the intensity -duration -frequency curves for the specified design return period at the time of concentration, tc (in/h
or mm/h). tc = time of concentration (time after the beginning of rainfall
excess when all portions of the drainage basin are contributing
simultaneously to flow at the outlet).
A = area of tributary watershed (acres or km2) The rational equation is used to calculate the runoff from a region, given:
• the runoff coefficient which accounts for infiltration and other potential
losses in th e region,
• the rainfall intensity to the region,
• the time it takes for runoff to travel from the region's upper reaches to its outlet, and the region's drainage area.

A. (4.) ACUTE TOXICITY MONITORING (ANNUAL)
[15A NCAC 02B .0500 et seq.]

The permittee shall conduct acute toxicity tests on an annual basis using protocols defined as definitive
in E PA Document EPA-821-R-02-012 entitled “Methods for Measuring the Acute Tox icity of Effluents and Receiving Waters to Freshwater and Marine Organisms.” The monitoring shall be performed as a
Fathead Minnow (Pimephales promelas) 24 hour static test. Effluent samples for self -monitoring
purposes must be obtained during representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge below all waste t reatment processes.

The parameter code for Pimephales promelas is TAE6C. All toxicity testing results required as part of
this permit condit ion will be entered on the Effluent Discharge Form (MR-1) for the month in which it was performed, using the appropriate parameter code. Additionally, DWR Form AT-1 (original) is to be
sent to the following address:
Attention: North Carolina Divisio n of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Or, results can be sent to the email, [e-mail].
Completed Aquatic Toxicity Test Forms shall be filed with the Water 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 and accurate and include all supporting chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine
of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of
the waste stream.
Should any test d ata f rom either these monitoring requirements 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.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival 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. (5.) ELECTRONIC REPORTING - DISCHARGE MONITORING REPORTS [G.S. 143-215.1(b)]

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.

NOTE: This special condition supplements or supersedes the following sections within Part II of this permit (Standard Conditions for NPDES Permits):

• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)]
The permittee shall report 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 int ernet. Th e eDMR system may be accessed at: https://deq.nc.gov/about/divisions/water-resources/edmr.

If a permittee is unable to use the eDMR system due to a demonstrat ed 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 D MR forms (MR 1, 1.1, 2, 3) or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the following address:

NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central File s
1617 Mail S ervice Center
Raleigh, North Carolina 27699-1617
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 t he following compliance monitoring data and reports, when applicable:

NPDES Permit NC0021971
Page 9 of 10

• Sewer Overf low /B ypass Event Report s;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA ) Section 316(b) Annual Reports.

 NPDES Electronic Reporting Rule – Phase 2 Extension. EPA is proposing to extend
the Phase 2 deadline from December 21, 2020 until at least D ecember 21, 2023. The
current compliance date will be extended if t he implementation date is extended as a final regulation change in the federal register.

The permittee may seek an electronic reporting waiver from the Division (see “How to Request a
Waiver from Electronic Reporting” section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(l)(9), the permittee must identify the initial recipient at the t ime
of each electronic submission. The permittee should use the EPA’s w ebsite resources to identify the
initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated ent ity
for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA’s NPDES
Electronic Reporting Rule is found at: https://www.federalregister.gov/documents/2015/10/22/2015-
24954/national-pollutant -discharge-elimination -system-npdes-electronic-reporting-rule
Electronic submissions must start by the dates listed in t he “Reporting Requirement s” section above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary elect ronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an elect ronic reporting w aiver 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 und er 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 t he Division unless the permittee re-applies for and is granted a new t emporary electronic reporting waiver by the Division. Approved electronic reporting
waivers are not transferrable. Only permittees with a n approved reporting waiver request may
submit monitoring data and reports on paper to t he Divisio n for the period that the approved reporting waiver request is effective.

Information on eDMR and the application f or a temporary electronic reporting waiver are found on
the following web page: http://d eq.nc.gov/about/divisions/water-resources/edmr
