Wilmington Terminal, WPCS PC-1
1002 S. Front St, Wilmington, NC 28401
New Hanover County
Mr. Summers:

On July 7, 2021, The Division of Water Resources (DWR or the Division) received your
application to renew the subject permit for discharge to surface waters of the State. We hereby
provide this draft for your review and comment.

Please review this draft carefully to ensure your understanding of its limits and monitoring
requirements. Concurrent with this transmission, the Division will solicit public comment by
publishing a notice in newspapers having circulation in the general New Hanover County area, as
required by the NPDES Program. Please submit your written comments (if any), attention
NCDEQ / DWR / NPDES, attention Wren Thedford, no later than July 12, 2022 (approximately
30 days after receiving this document). We welcome your written comments, but they are not
mandatory.

Please note that the receiving stream, the Cape Fear River, is listed as impaired for aquatic life on
the North Carolina 2020 303(d) Impaired Waters List. Addressing impaired waters is a high
priority with the Division as we continue to evaluate instream data. If you report noncompliance
with permitted effluent limits and stream impairment may be attributed to your facility, DWR
may require mitigative measures.

Monthly Report Submittals: Federal regulations require electronic submittal of all program
reports and Monthly Discharge Monitoring Reports (DMRs). Please note that CTI must continue
to report using the Electronic Discharge Monitoring Report (eDMR) programs permit [see permit
section A. (8.)].

Renewal - Draft Permit Review
Jun2022
Page 2

Summary of Changes for Renewal:
1) updated Site Map and permit text for Electronic Reporting [section A. (8.)]
2) renewal continues to require test methods EPA 624/625, hereby updated to 624.1 and
625.1 with revised text [see section A. (1.) and Special Condition Additional Monitoring
and Reporting Requirements A. (7.)]. For your convenience, this Special Condition
provides a reference for reporting parameters on monthly eDMRs, if detected.
3) discontinued monitoring for Total Suspended Solids (TSS) because the receiving stream is
not impaired for TSS
4) revised Turbidity units from 25 NTU to 50 NTU because the receiving steam is classified
SC and it is not impaired for Turbidity
5) deleted previous Footnote 6. [Sections A. (1.) and A. (2.)] addressing Naphthalene (not
applicable)
6) added pH monitoring to both outfalls [required by EPA of industrial permits].
7) corrected Oil & Grease (O&G) parameter code from 00556 to 00552 [reference EPA
Method 1664 (SGT-HEM) intended to target petroleum hydrocarbons rather than soaps/fats]
8) Outfall 001 Only - Whole Effluent Toxicity (WET) testing -- DWR hereby replaces Acute
TAE6C with saltwater Chronic EPA Method 1007.0 Mysid shrimp, P/F Permit Limited
(see Rationale below).
Rationale for Chronic Whole Effluent Toxicity (WET) Testing at Outfall 001:
a. CTI combines remediated groundwater and stormwater discharging continuously at Outfall 001.
In accord with permitting guidance, DWR defines this effluent as chemically complex. A
Complex wastestream with continuous flow requires a Chronic WET test [see Director’s Memo –
Colene Sullins, 1999].
b. DWR evaluates WET using aquatic test species and the flow ratio of effluent vs. the receiving
stream, or the instream waste concentration (IWC) expressed as a percentage. However, CTI
discharges to SC waters (influenced by ocean tides - no evident 7Q10 stream flow) where the
IWC has not been quantified and may not be quantified without CTI’s further study.
c. Assigning an alternate WET-test method may require a dilution study to establish an IWC.
Upon request, CTI may initiate this study to establish alternate testing considering saltwater vs.
freshwater to be performed in accord with methods establish by the Division [see Director’s
Memo – Colene Sullins, 1999].
d. It follows therefore, that until the Permittee may request approval for further study, DWR shall,
for renewal at Outfall 001 only, replace acute test TAE6C with Chronic test EPA Method
1007.0 - Mysid Shrimp (Mysidopsis bahia), Pass/Fail, permit limited for saltwater. This test is
performed at 90% effluent concentration, monitored Quarterly [see permit section A. (1.) and
A. (5.)].

layer; no tank [or pipe] contents unless Toluene concentrations test less than 370 and Benzine
concentrations are below 1.8 µg/L.

A. (3.) FLOW MEASUREMENT RATIONAL [G.S. 143-215.1(b)]
The Rational Method - Determination of Peak Runoff:
[REF: FHWA Urban Drainage Design Manual, 3.2.2. Rational Method (3-1)]
Q=KuCIA, where:
Q = flow (peak flow rate in cfs or m3/sec)
Ku = unit conversation factor = 1.008 for U.S. standard units (usually ignored
because it is so close to 1), or 0.278 for metric 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 beginning rainfall excess when all portions of
the drainage basin are contributing simultaneously to outlet flow).
A = area of tributary watershed (acres or km2)
The rational equation is used to calculate the runoff from a region, given:
• the runoff coefficient (accounts for infiltration losses in the region),
• the rainfall intensity to the region,
• the time for runoff to travel from the region's upper reaches to its outlet, and
• the region's drainage area.

A. (4.) PERMIT RE-OPENER: TMDL IMPLEMENTATION
[G.S. 143-215.1(b)]

The Division may upon written notification to the Permittee, re-open this Permit in order to incorporate or modify
effluent limitations, monitoring and reporting requirements, and other permit conditions when it deems such
action is necessary to implement TMDL(s) approved by the U. S. EPA.

A. (5.) CHRONIC TOXICITY PASS/FAIL (QUARTERLY) – Outfall 001
[15A NCAC 02B .0500 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of growth or significant mortality to
Mysidopsis bahia at an effluent concentration of 90%.

The permit holder shall perform at a minimum, quarterly monitoring using procedures described below
to establish compliance with the permit condition. 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 EPA Method 1007.0, Mysid, Mysidopsis bahia,
Survival, Growth, and Fecundity Test, as described in Short-Term Methods for Estimating the
Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms, Third
Edition, EPA821-R-02-014, October 2002.

The test procedure will be based on EPA Method 1007.0, Mysid, Mysidopsis bahia, Survival, Growth,
and Fecundity Test, as described in Short-Term Methods for Estimating the Chronic Toxicity of Effluents
and Receiving Waters to Marine and Estuarine Organisms, Third Edition, EPA-821-R-02-014, The
procedure will be performed as written with the following exceptions:
• The test treatments will consist of a control and a (put IWC here)_% effluent
concentration (“pass/fail,”) or a control and five effluent concentrations, one of which
will be _(put IWC here)_% and one of which will be (1/2 the IWC)__%.
• Mortality for pass/fail tests will be evaluated using the t test described in Section 11.3 in
Methods for Measuring the Acute Toxicity of Effluents to Freshwater and Marine
Organisms, Fifth Edition. EPA—821-R-02-012, October 2002, applying an alpha level of
0.05.
• The growth endpoint for pass/fail tests will be determined using Appendix G of Short-
Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to
Marine and Estuarine Organisms, Third Edition, EPA-821-R-02-014, October 2002,
applying an alpha level of 0.01.
• Mortality and growth endpoints for multiple-concentration tests will be determined using
hypothesis testing as described in EPA Method 1007.0, Mysid, Mysidopsis bahia,
Survival, Growth, and Fecundity Test, as described in Short-Term Methods for
Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and
Estuarine Organisms, Third Edition, EPA-821-R-02-014, October 2002.
• Fecundity will not be evaluated.
NPDES Permit NC0082970

All toxicity testing results required as part of this permit condition will be entered electronically using
the Division’s eDMR system for the months in which tests were performed. For pass/fail results, report
using the parameter code TGP3E and for reporting Chronic Value results use the parameter code
THP3E. Additionally, DWR Form AT-4 (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, [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, 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
Water Sciences Section at the address cited above.

Should the permittee 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.

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.

NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism growth, 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. (6.) ACUTE TOXICITY PASS/FAIL LIMIT (QUARTERLY) – Outfall 003
[15A NCAC 02B .0200 et seq.]

The permittee shall conduct acute toxicity tests on a Quarterly basis [except when approved Annually]
using protocols defined in the North Carolina Procedure Document entitled “Pass/Fail Methodology For
Determining Acute Toxicity In A Single Effluent Concentration” (Revised December 2010 or subsequent
versions). The monitoring shall be performed as a Mysid Shrimp (Mysidopsis bahia) 24-hour static test.
The effluent concentration at which there may be at no time significant acute mortality is 90% (defined
as treatment two in the procedure document). 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.

Should any single quarterly monitoring indicate failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.

All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code
TGE3E. Additionally, DWR Form AT-2 (original) is to be sent to the following address:

A. (8.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORT S [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 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 DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
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. 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
· 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).
NPDES Permit NC0082970
Page 16 of 17

2. Electronic Submissions
In accordance with 40 CFR 122.41(l)(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-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
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)]
All eDMRs submitted to the permit 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, please visit the following web
page:
http://deq.nc.gov/about/divisions/water-resources/edmr

Certification. Any person submitting an electronic DMR using the state’s eDMR system shall make the
following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION WILL BE
ACCEPTED:
"I certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or persons
who manage the system, or those persons directly responsible for gathering the information, the
information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am
aware that there are significant penalties for submitting false information, including the possibility of
fines and imprisonment for knowing violations."
5. Records Retention [Supplements Section D. (6.)]
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR submissions.
These records or copies shall be maintained for a period of at least 3 years from the date of the report.
This period may be extended by request of the Director at any time [40 CFR 122.41].
