Subject: Draft NPDES Permit NC0004839
Charlotte Terminal 2
Grade I Physical Chemical WPCS
Mecklenburg County
Dear Permittee:
The Division has reviewed your request to renew the subject permit.Enclosed with this letter is a copy of the draft
permit for your facility.Please review this draft carefully to ensure your thorough understanding of the
information,conditions,and requirements it contains.
The draft permit includes the following significant changes from the existing permit:
> The limit for Turbidity has been removed from the Effluent table in Section A. (1.)as this parameter did
not demonstrate reasonable potential to exceed applicable water quality standards/criteria.Monitoring for
this parameter is still required,as per current permitting strategy.
➢ EPA Method 625 has been removed from the Effluent table in Section A. (1.)as no parameters were
detected during the previous permit cycle,per current permitting strategy.
> Section A. (2.)has been updated to include new electronic submission information for testing results.
> Section A. (4.) has been updated regarding electronic submission of effluent data. Federal regulations
require electronic submittal of all discharge monitoring reports(DMRs).
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.
With this notification,the Division will solicit public comment on this draft permit by publishing a notice in
newspapers having circulation in the general Mecklenburg County area,per EPA requirements.Please provide
your comments,if any,to me at the address below no later than 30 days after receiving this draft permit.
Following the 30-day public comment period,the Division will review all pertinent comments and take
appropriate action prior to issuing a fmal permit.If you have questions concerning the draft,please contact me at

Footnotes:
1. The permittee shall submit discharge monitoring reports electronically using the Division's eDMR system [see
Section A. (4)].
2. Flow shall be monitored with each discharge event—During periods of no flow,the Permittee shall submit a
signed, 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, Section A. (3)]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.
3. Effluent turbidity shall not cause receiving-stream turbidity to exceed 50 NTU. If background turbidity
naturally exceeds 50 NTU,the effluent shall not cause background turbidity to increase.Non-compliance
with this standard may require additional stream monitoring and a Turbidity Corrective Action Plan
(TCAP).
4. The Permittee shall acquire samples concurrently with Acute Toxicity sampling.
5. Provided that the Permittee can demonstrate to the Division that its facility does not now,nor has ever,
stored diesel fuel or other heavy fuels, it may petition to remove monitoring for naphthalene.

6. Acute Toxicity(Fathead Minnow—Pimephales promelas)24-hour Annual test. [See Section A. (2).]
7. Where possible,the grab sample for Oil and Grease should be skimmed from the surface of a quiescent
(calm water)zone.
Conditions:
• The Permittee shall discharge no 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.
A. (2.) ACUTE TOXICITY MONITORING(ANNUAL)
[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 results required as part of this permit
condition will be entered electronically using the Division's eDMR system for the month in which it
was performed. Additionally, DWR Form AT-1 (original)is to be sent to the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,NC 27699-1621
Or,results can be sent to the email, ATForms.ATB@a,ncdenr.gov.
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch 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 Quality indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.

NPDES Permit NC0004839
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. (3.) RATIONAL EQUASION FOR CALCULATING FLOW
[G.S. 143-215.1(b)]
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.
A. (4.) 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 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

NPDES Permit NC0004839
1. Reporting Requirements [Supersedes Section D.(2.)and Section E.(5.)(a)l
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
monitoringdata and submit DMRs electronically
e ectronically using the internet. The eDMR may system be
Y Y
accessed at: https://deq.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 21,2025, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• 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.federalregister.gov/documents/2015/10/22/2015-24954/national-pollutant-discharge-
elimination-system-npdes-electronic-reporting-rul e
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
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B.(11.) (d)l
