Mecklenburg County
Dear Mr. Krejci:
Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft very
carefully to ensure thorough understanding of the conditions and requirements it contains. Your
permit is among several in the Catawba River Basin that the Division has targeted for expedited
renewal.
This draft contains the following changes from the existing permit:
• The outfall description on the supplement to cover page is updated to include the
HUC.
• Parameter codes in the effluent tables have been corrected.
• The language in section A.(5) has been updated to be consistent with the finalization
of federal requirements for electronic reporting.
• Toxicity reporting requirements have been updated in A (3) and A (4) to include
guidance for electronic submission.
• Previously, footnote 5 of Section A (1)/(2) required toxicity tests to be collected
concurrent with BTEX samples. Concurrent sampling is no longer a DWR
requirement. This footnote has been removed.
• The footnote corresponding to the oil and grease parameter has been removed. This
footnote does not apply to the current method.
• A new footnote (footnote 4) was added to Section A(1)/(2). This footnote clarifies
how to correctly report results for EPA method 625 (Semi Volatile Organic
Compounds).
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. The latest version is available at https://bit.ly/2BZ4xxx and can be viewed online
or downloaded as a PDF file.

Permit NCO032891
Footnotes for A. (1.) / A. (2.)
1. The permittee shall submit discharge monitoring reports electronically using the Division's eDMR system [see A. (5)].
2. Flow —shall be monitored with each discharge event— During periods of no flow, the Permittee
shall submit a monthly electronic Discharge Monitoring Report (eDMR) indicating "No discharge."
Flow may be monitored using any one of the following four methods:
a) measure flow continuously;
b) calculate flow (see Rational Equation below) based on total rainfall per unit area
draining to the outfall; exclude built -upon areas (best method for facilities with large
runoff -collection ponds);
c) estimate flow at 20-minute intervals during the entire discharge event; or
d) report flow based on discharge pump logs."
The Rational Equation: Q=KuCIA, where:
Q = flow (peak flow rate (cfs or m3/sec)
Ku = units conversation factor = 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 of 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 the
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.
3. Turbidity — Effluent shall not cause receiving stream turbidity to exceed 50 NTU. If receiving stream
background turbidity exceeds 50 NTU, effluent shall not cause this background value to increase.
4. For the eDMR application system, any detections shall be reported by entering "1" [Yes (Y) = 1 ] and no detection
shall be reported by entering "0" [NO (N) = 0]. Any detections for Total Purgeables Organics (EPA Method 624)
or Base Neutrals & Acids (EPA Method 625) shall be noted in the comments section by recording the compound
detected and reported concentration. Laboratory reports shall be kept on file in accordance with records retention
requirements found in Part II. Section D. 6.
5. Acute Toxicity Outfall 001 (Fathead Minnow, 24-hour), Annual [see Special Condition A. (3.)]
If any annual WET tests "fail", the Permitee shall immediately revert to Quarterly testing in accordance
with A (4.).
6. Acute Toxicity Outfall 002 (Fathead Minnow, 24-hour), Annual [see Special Condition A. (4.)].
If any annual WET tests "fail", the Permitee shall immediately revert to Quarterly testing in accordance
with A (4.).
Additional Requirements
• There shall be no discharge of floating solids or foam visible in other than trace amounts.
• There shall be no direct discharge of tank solids, tank bottom water, or the rag layer.
• There shall be no direct discharge of tank (or pipe) contents following hydrostatic testing unless benzene
concentration is less than 1.19 µg/L and toluene concentration is less than 11 µg/L.

Permit NCO032891
A. (3.) ACUTE TOXICITY MONITORING (Annually) — OUTFALL 001
[15A NCAC 02B .0500 et seq.]
The Permittee shall conduct annual toxicity tests using protocols defined as definitive in EPA Document
EPA/600/4-90/027 entitled "Methods for Measuring the Acute Toxicity of Effluents 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 below all waste
treatment. The permittee will conduct one test annually, with the annual period beginning in January of
the calendar year of the effective date of the permit. The annual test requirement must be performed and
reported by June 30. If no discharge occurs by June 30, notification will be made to the Division by this
date. Toxicity testing will be performed on the next discharge event for the annual test requirement.
The parameter code for this test is TAE6C. All toxicity testing required as part of this permit will be
entered electronically using the Division's eDMR system 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 Division of Water Resources
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Or, results can be sent to the email, ATForms.ATB(&ncdenr.gov.
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 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 data from either these monitoring requirements 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.
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.

Permit NCO032891
A. (4.) ACUTE TOXICITY MONITORING (Quarterly) — OUTFALL 002
[ 15A NCAC 02B .0500 et seq.]
The Permittee shall conduct quarterly acute toxicity tests [Except when relaxed to Annually] using
protocols defined as definitive in E.P.A. Document EPA/600/4-90/027 entitled "Methods for Measuring
the Acute Toxicity of Effluents 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 below all waste treatment. The tests will be performed on a
discharge event during each quarter (January -March, April -June, July -September, October -
December) [Except when relaxed to Annually].
Should there be no discharge of flow from the facility during a quarter 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 below.

A. (5) ELECTRONIC REPORTING OF 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 11 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)1
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 internet. The eDMR system may be
accessed at: https:Hdeq.nc.gov/about/divisions/water-resources/edmr.
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
following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service 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 the following compliance
monitoring data and reports, when applicable:
Sewer Overflow/Bypass Event Reports;
Pretreatment Program Annual Reports; and
Page 7 of 9

• Clean Water Act (CWA) Section 316(b) Annual Reports.
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(1)(9), the permittee must identify the initial recipient at the time of
each electronic submission. The permittee should use the EPA's website 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 entity
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.federalre isg ter.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 the "Reporting Requirements" section above.
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.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
http://deq.nc.gov/about/divisions/water-resources/edmr
