Mr. Summers:
The Division of Water Resources(DWR or the Division)has noticed an error in your active permit issued
earlier this year, effective February 1,2023.We have attached a corrected permit for your records.
DWR notes that your active Whole Effluent Toxicity(WET), Chronic,parameter code(TGP3E)was
incorrectly applied to your effluent at Outfall 001. The corrected WET test(TGE3E),Acute using Mysid
Shrimp (Mysidopsis Bahia) 24-hour static test, is hereby substituted[see sections A. (L)and A. (5.)].
Please discard your previous permit and replace it with the attached. If you have questions,or if we can
further assist you,please contact Joe R. Corporon,P. G. of my staff [e-mail]].

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.) ACUTE TOXICITY PASS/FAIL MONITORING (QUARTERLY)
[15A NCAC 02B .0500 et seq.]
Except for monitoring approved by DWR as Annually, the permittee shall conduct acute toxicity tests on
a quarterly basis 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.
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,using the parameter code
TGUE. Additionally, DWR Form AT-2 (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(�i),ncdenngov.
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.
Page 6 of 15

DocuSign Envelope ID:Al D7C99B-CD30-4912-9EA6-4CBED33E9C63
NPDES Permit NCO082970
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then
monthly monitoring will begin immediately. Upon submission of a valid test, this monthly test
requirement will revert to quarterly in the months specified above.
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.
USE OF A DIFFERENT TEST ORGANISM
The permittee may request the use of a different test organism upon documentation that the alternate test
organism would provide an equal or greater level of protection and is appropriate based on the
characteristics of the discharge and receiving stream. Such documentation would consist of one of the
following:
1. For saltwater classified streams, a fathead minnow may be assigned as the acute testing species if
the salinity of the receiving stream at the point of discharge is <5 ppt throughout the tidally
influenced cycle. This determination may be based on the best professional judgment of DWQ
staff or data collection provided by the permittee and approved by DWQ staff. This evaluation
should include vertical profiles of salinity/conductivity measurements at both high tide and low
tide over several 24 hr cycles.
2. Three consecutive "side-by-side" tests with results indicating that the alternate test organism is
as or more sensitive to the facility's effluent. Each test series would consist of two separate
toxicity tests conducted on the same sample of effluent with the length of exposure specified by
the permit, the only difference between the tests being the organism used.
3. An alternate plan developed by the permittee and approved by the Aquatic Toxicology Unit that
demonstrates an equal level of protection is offered by the test organism.
For items 2 and 3, it must also be demonstrated that viable and standardized culture techniques are
available for that organism and standardized testing methodologies have been developed and validated.
This demonstration should meet guidance provided by EPA in Section 6 of EPA-821-R-02-012, Short
Term Methods for Estimating the Acute Toxicity of Effluents and Receiving Waters to Freshwater
Organisms. Fifth Edition, 2002. Requests to use a different test organism and supporting documentation
should be sent to NC DWQ, ESS at the address listed above.
A. (6.) ADDITIONAL MONITORING AND REPORTING REQUIREMENTS
[G.S. 143-215.1(B)]
(a.) EPA Method 624.1—Organics,Total Purgeables (VOCs).The permittee shall conduct Semi-annually
effluent pollutant scans using protocols as defined in E.P.A. Document EPA 821-R-16-008 entitled"Method

A. (7.) 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
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
Page 13 of 15

DocuSign Envelope ID:Al D7C99B-CD30-4912-9EA6-4CBED33E9C63
NPDES Permit NC0082970
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).
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-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
Page 14 of 15

DocuSign Envelope ID:Al D7C99B-CD30-4912-9EA6-4CBED33E9C63
NPDES Permit NC0082970
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.ne.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. (I 1.)(a) or by a duly authorized representative of that person as described in Part II, Section
B. (I 1.)(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:

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.

Mr. Summers:
The Division of Water Resources (the Division or DWR)hereby issues the attached NPDES permit
for the subject facility. We issue this pursuant to the requirements of North Carolina General Statute
143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental
Protection Agency dated October 15, 2007, or as subsequently amended.
Comments on Draft--Thanks to CTI for its review and comments on the draft permit(Tom Dolan,
received July15, 2022). DWR addresses these comments as follows.
1. Supplement to Permit Cover Sheet [A. (1.)]:per your request,we have added"steam condensate"
to the description of treated effluent.
2. Turbidity [A. (1.)and A. (2)]:per your request,DWR has corrected the Turbidity footnote to
reflect State regulations. We have also reduced Turbidity limits from 50 NTU to 25 NTU
consistent with the classification of the receiving stream.
3. Total Suspended Solids [A. (1.)] although this parameter was deleted from the draft,it is hereby
reinstated because TSS monitoring is required of all industrial facilities by EPA.
4. Methanol [A. (1)1: per your request,DWR has deleted monitoring as Methanol is no longer a
parameter of concern.
5. BOD-5 [A. (1)]: DWR has discontinued permit limits and reduced monitoring frequency from
Monthly to Quarterly.
6. BTEX [A. (1.)]: These analytes remain parameters of concern (POCs)for ongoing groundwater
remediation at Outfall 001. However,based on the monitoring record(no detection above lab
PQL since March 2018),monitoring is hereby reduced from Monthly to Quarterly.
7. WET testing [A. (1.): Regarding effluent flow,regardless of continuous or episodic,DWR
judges all groundwater remediation effluents statewide to be"complex"wastestreams.
8. Turbidity [A. (L)and A. (2.)]: footnotes and texts for Turbidity have been corrected from 50
NTU to 25 NTU to reflect receiving-stream conditions.

Page 2
Summary of Changes for Renewal:
• updated permit text and Site Map
• Monitoring for BTEX reduced from Monthly to Quarterly
• renewal continues to require test methods EPA 624/625, hereby updated
to 624.1 and 625.1 with revised text [see section A. (L) and related
Special Condition Additional Monitoring and Reporting Requirements A.
(6.)] providing for eDMR reporting of any analyte detected.
• Turbidity limits in the draft permit have been reduced from 50 NTU to 25 NTU
in accord with the stream classification [Sections A. (L) and A. (2.)]
• deleted previous Footnote 6. [Sections A. (L) and A. (2.)] addressing
Naphthalene (no longer a parameter of concern)
• added pH monitoring to both outfalls [required by EPA of industrial permits]
• corrected Oil & Grease (O&G)parameter code from 00556 to 00552 [EPA
method 1664 (SGT-HEM) intended to target petroleum hydrocarbon
products rather than soaps/fats]
• WET Change- Outfall 003 Only—DWR hereby discontinues Whole Effluent
Toxicity(WET) at Outfall 003 [best professional judgement] considering a
stormwater effluent(simple wastestream) and an instream waste concentration
(IWC)ratio of less than 0.25%
• WET Change- Outfall 001 Only - Whole Effluent Toxicity(WET)testing --
DWR hereby replaces Acute TAE6C with Chronic saltwater EPA Method 1007.0
Mysid shrimp, P/F, Limited (see Rationale below). Despite the dilution afforded
(estimated IWC <0.25%), DWR feels WET is warranted due a complex
wastestream.
Rationale for Chronic (WET) Testing at Outfall 001 only:
1. CTI combines remediated groundwater and stormwater discharging continuously at Outfall
001. DWR must therefore define this effluent as chemically complex. Complex wastestreams
with continuous flow require Chronic WET testing [see Director's Memo—Colene Sullins,
1999].
2. 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. IWC
0.0038 %was calculated assuming flow 3,900 MGD (East Cape Fear River).
3. Assigning an alternate WET test method to such effluents may require a dilution study. Upon
request, CTI may initiate this study to establish alternate test species considering saltwater vs.
freshwater if this study is performed in accord with methods establish by the Division
[Director's Memo—Colene Sullins, 1999].

4. Therefore, until the Permittee may request approval for further study, DWR hereby replaces
acute WET test TAE6C with Chronic WET test EPA Method 1007.0 -Mysid Shrimp
(Mysidopsis bahia), Pass/Fail,permit limited for saltwater, monitored Quarterly [see permit
section A. (1.) and A. (5)].
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 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 -7Q10 stream flow estimated only). IWC
has not been established 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, 19991.
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 sections
A. (1.) and A. (5.)].
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. (7.)].
If any parts,measurement frequencies, or sampling requirements contained in this permit are unacceptable,
you have the right to an adjudicatory hearing,upon written request submitted within thirty(30)days after
receiving this letter. Your request must take the form of a written petition conforming to Chapter 150B of
North Carolina General Statutes, and you must file it with the Office of Administrative Hearings, 6714 Mail
Service Center,Raleigh,North Carolina 27699-6714.Unless such a demand is made,this permit shall remain
final and binding.

2. The Permittee shall monitor each discharge event recording flow volume and flow duration. During
periods of no flow,the Permittee shall submit a signed,monthly Discharge Monitoring Report(DMR)
indicating"No discharge."Flow may be documented using any one of the following four(4)methods:
1) measure flow continuously via weir or flow meter(totalizer preferred)
2) estimate flow at 20-minute intervals during the entire discharge event
3) report flow based on discharge pump logs; or
4) calculate flow based on total rainfall per unit area draining to the outfall using the
Rational Method[see formula, Section A. (3)].
3. Turbidity: the turbidity in the receiving water shall not exceed 25 NTU; if turbidity exceeds this level due to
natural background conditions,the existing turbidity level shall not be increased. (NCAC 02B. 0220(19).
4. All laboratory practical quantitation limits(PQLs)must be sufficiently sensitive to consider each
parameter's respective surface water quality standard[see Part II. Section D. (4)].
Conditions:
• There shall be no discharge of floating solids or foam visible in other than trace amounts.
• Direct discharge of tank solids,tank-bottom water,or the rag layer is not permitted.
• Hydrostatic Tank Testing: the Permittee shall discharge no tank solids,no tank bottom-water,no tank rag-
layer, no tank [or pipe] contents unless Toluene concentrations test less than 370 µg/L 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.

[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 0.0038 %.
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 0.0038 % effluent concentration
("pass/fail,") or a control and five effluent concentrations, one of which will be 0.0038 %
and one of which will be 0.0019 %.
• 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. EPA821-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-82 1-R-02-014, October 2002.
• Fecundity will not be evaluated.

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.

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).
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-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. (I 1.)(a) or by a duly authorized representative of that person as described in Part II, Section
B. (I 1.)(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:

"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.

the Permittee's(or any satellite POTW's,if different from the Permittee)NPDES,collection system,or non-discharge
permit. [15A NCAC 02H.0903(b)(23)]
Publicly Owned Treatment Works(POTW)
A treatment works as defined by Section 212 of the CWA,which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage,treatment,recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system,as defined in 15A NCAC 2T
.0402,only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization,or municipality, as defined in section 502(4)of the CWA,which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context,the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a"satellite POTW organization." [15A NCAC 02H.0903(b)(26)]
"Significant Industrial User" or"SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H

noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non-discharge permitted
flow limit or organic capacity of the POTW treatment plant.In this context, organic capacity refers to BOD,TSS
and ammonia;or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement,or the POTW's effluent
limitations and conditions in its NPDES or non-discharge permit,or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b),the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement,the POTW's effluent limitations and
conditions in its NPDES or non-discharge permit,or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User(SIU);or
6. Subject to approval under 15A NCAC 02H .0907(b),the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2)and thus is a

Facility Summary:
CTI of North Carolina-Wilmington Terminal(herein CTI) is a hydrocarbon fuel, surface bulk-storage
facility,a 100%industrial,minor discharger[flow<1 MGD]. The permit renewal application for this
Surface Water Pollution Control Program states that the Permittee has"...made no significant changes to
the treatment systems..."since last renewal. This discharge combines stormwater and treated groundwater
held in proximity to aboveground storage tanks(ASTs). Because surface bulk storage exceeds one million
gallons,treated effluents do NOT qualify for the Division's Stormwater Permit. Currently active point-
source facilities are described as:
• Both Outfalls 001 & 003 -treatment systems consisting of
o gravity-type oil/water separator
o mechanical skimmers
o waste-product holding/storage tanks
• Outfall 001 ONLY-a groundwater remediation system [design flow 0.014 MGD,no
permit limit];this discharge combines stormwater and remediation wastewater utilizing
o an oil/water separator
o air stripper
o particulate filters
o activated carbon

Summary of Changes for Renewal:
1. updated permit text and Site Map
2. BTEX monitoring reduced from Monthly to Quarterly [not detected above
lab PQL since March 2018]
3. 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 related Special
Condition Additional Monitoring and Reporting Requirements A. (6.)]
providing for eDMR reporting of any analyte detected.
4. Turbidity limits in the draft permit have been reduced from 50 NTU to 25 NTU in
accord with the stream classification [Sections A. (1.)and A. (2.)]
5. deleted previous Footnote 6. [Sections A. (1.)and A. (2.)] addressing
Naphthalene(no longer a parameter of concern)
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 [EPA
method 1664(SGT-HEM)intended to target petroleum hydrocarbon products
rather than soaps/fats]
8. WET Change-Outfall 003 Only—DWR hereby discontinues Whole Effluent
Toxicity(WET) at Outfall 003 [best professional judgement] considering a
stormwater effluent(simple wastestream)and an instream waste concentration
(IWC)ratio of less than 0.25%
9. WET Change-Outfall 001 Only-Whole Effluent Toxicity(WET)testing--DWR
hereby replaces Acute TAE6C with Chronic saltwater EPA Method 1007.0 Mysid
shrimp,P/F,Limited(see Rationale below).Despite the dilution afforded(estimated
IWC<0.25%),DWR feels WET is warranted due a complex wastestream.
Rationale for Chronic (WET)Testing at Outfall 001 only:
1. CTI combines remediated groundwater and stormwater discharging continuously at Outfall 001.
DWR must therefore define this effluent as chemically complex. Complex wastestreams with
continuous flow require Chronic WET testing [see Director's Memo—Colene Sullins, 1999].
2. 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 7Q 10 stream
flow)where the IWC has not been quantified and may not be quantified without CTI's further
study. IWC 0.0038 %was estimated assuming flow 3,900 MGD (East Cape Fear River).
3. Assigning an alternate WET test method to such effluents may require a dilution study.Upon
request, CTI may initiate this study to establish alternate test species considering saltwater vs.
freshwater if this study is performed in accord with methods establish by the Division
[Director's Memo—Colene Sullins, 1999].
4. Therefore,until the Permittee may request approval for further study,DWR hereby replaces
acute WET test TAE6C with Chronic WET test EPA Method 1007.0-Mysid Shrimp
(Mysidopsis bahia),Pass/Fail,permit limited for saltwater,to be performed at 0.0038%
effluent concentration,monitored Quarterly [see permit section A. (1.)and A. (5.)].

Impaired Receiving Stream: The receiving-stream segment [18-(71)a3] is listed as Impaired for aquatic
life,2020 Integrated Report 303(d) list.
Monitoring for BOD5 and Methanol: The renewal application reports Methanol detected in 3 instances
during the previous permit cycle. In two of these reports,B0135 was also elevated. The Permittee perceives
this to indicate organic concentrations related to Methanol,therefore the Permittee requests that monitoring
of 130135 continue. Considering that Methanol has no surface water quality standard,DWR has no objection
to renewing the Permittee's request.

NPDES Implementation of Instream Dissolved Metals Standards — Freshwater
The NC 2007-2015 Water Quality Standard(WQS) Triennial Review was approved by the NC
Environmental Management Commission(EMC) on November 13,2014. The US EPA subsequently
approved the WQS revisions on April 6,2016,with some exceptions. Therefore,metal limits in draft
permits out to public notice after April 6,2016 must be calculated to protect the new standards -as
approved.
Table 1 Notes:
1. FW=Freshwater, SW= Saltwater
2. -=Hardness dependent standard
3. Only the aquatic life standards listed above are expressed in dissolved form. Aquatic life standards
for Mercury and selenium are still expressed as Total Recoverable Metals due to bioaccumulative
concerns(as are all human health standards for all metals). It is still necessary to evaluate total
recoverable aquatic life and human health standards listed in 15A NCAC 213.0200(e.g., arsenic at
10 µg/l for human health protection; cyanide at 5 µg/L and fluoride at 1.8 mg/L for aquatic life
protection).

General Information on the Reasonable Potential Analysis(RPA)
The RPA process itself did not change as the result of the new metals standards. However, application of
the dissolved and hardness-dependent standards requires additional consideration in order to establish the
numeric standard for each metal of concern of each individual discharge.
The hardness-based standards require some knowledge of the effluent and instream(upstream)hardness and
so must be calculated case-by-case for each discharge.
Metals limits must be expressed as `total recoverable' metals in accordance with 40 CFR 122.45(c). The
discharge-specific standards must be converted to the equivalent total values for use in the RPA
calculations. We will generally rely on default translator values developed for each metal(more on that
below),but it is also possible to consider case-specific translators developed in accordance with established
methodology.
RPA Permitting Guidance/WQBELs for Hardness-Dependent Metals-Freshwater
The RPA is designed to predict the maximum likely effluent concentrations for each metal of concern,
based on recent effluent data, and calculate the allowable effluent concentrations,based on applicable
standards and the critical low-flow values for the receiving stream.
If the maximum predicted value is greater than the maximum allowed value(chronic or acute),the
discharge has reasonable potential to exceed the standard,which warrants a permit limit in most cases. If
monitoring for a particular pollutant indicates that the pollutant is not present(i.e. consistently below
detection level),then the Division may remove the monitoring requirement in the reissued permit.
1. To perform a RPA on the Freshwater hardness-dependent metals the Permit Writer compiles the
following information:
• Critical low flow of the receiving stream, 7Q 10(the spreadsheet automatically calculates
the 1 Q 10 using the formula 1 Q 10=0.843 (s7Q 10, cfs)0.993
• Effluent hardness and upstream hardness, site-specific data is preferred
• Permitted flow
• Receiving stream classification
2. In order to establish the numeric standard for each hardness-dependent metal of concern and for
each individual discharge,the Permit Writer must first determine what effluent and instream
(upstream)hardness values to use in the equations.

Page 6

DocuSign Envelope ID:A1D7C99B-CD30-4912-9EA6-4CBED33E9C63
The permit writer reviews DMR's,Effluent Pollutant Scans, and Toxicity Test results for any
hardness data and contacts the Permittee to see if any additional data is available for instream
hardness values,upstream of the discharge.
If no hardness data is available,the permit writer may choose to do an initial evaluation using a
default hardness of 25 mg/L(CaCO3 or(Ca+Mg)). Minimum and maximum limits on the
hardness value used for water quality calculations are 25 mg/L and 400 mg/L,respectively.
If the use of a default hardness value results in a hardness-dependent metal showing reasonable
potential,the permit writer contacts the Permittee and requests 5 site-specific effluent and upstream
hardness samples over a period of one week. The RPA is rerun using the new data.
The overall hardness value used in the water quality calculations is calculated as follows:
Combined Hardness(chronic)_
(Permitted Flow, cfs *Avg.Effluent Hardness,mg/L)x(s7Q10, cfs *Avg. Upstream Hardness,mg/L)
(Permitted Flow, cfs+s7Q 10,cfs)
The Combined Hardness for acute is the same but the calculation uses the IQ 10 flow.
3. The permit writer converts the numeric standard for each metal of concern to a total recoverable
metal,using the EPA Default Partition Coefficients(DPCs) or site-specific translators, if any have
been developed using federally approved methodology.
EPA default partition coefficients or the"Fraction Dissolved"converts the value for
dissolved metal at laboratory conditions to total recoverable metal at in-stream ambient
conditions.This factor is calculated using the linear partition coefficients found in The
Metals Translator: Guidance for Calculating a Total Recoverable Permit Limit from a
Dissolved Criterion(EPA 823-B-96-007,June 1996)and the equation:
Cdiss - 1
Ctotal 1 + { [Kpo] [ss("'] [10-6] l
Where: I
ss=in-stream suspended solids concentration[mg/1],minimum of 10 mg/L used,and
Kpo and a=constants that express the equilibrium relationship between dissolved and
adsorbed forms of metals.A list of constants used for each hardness-dependent metal can
also be found in the RPA program under a sheet labeled DPCs.
4. The numeric standard for each metal of concern is divided by the default partition coefficient(or
site-specific translator)to obtain a Total Recoverable Metal at ambient conditions.
In some cases,where an EPA default partition coefficient translator does not exist(i.e. silver),the
dissolved numeric standard for each metal of concern is divided by the EPA conversion factor to
obtain a Total Recoverable Metal at ambient conditions. This method presumes that the metal is
dissolved to the same extent as it was during EPA's criteria development for metals. For more
information on conversion factors see the June 1996 EPA Translator Guidance Document.

5. The RPA spreadsheet uses a mass balance equation to determine the total allowable concentration
(permit limits) for each pollutant using the following equation:
Ca=(s7Q 10+Qw) (Cwgs)-(s7Q I O) (Cb)
Qw
Where: Ca=allowable effluent concentration(µg/L or mg/L)
Cwqs=NC Water Quality Standard or federal criteria(µg/L or mg/L)
Cb=background concentration: assume zero for all toxicants except NH3* (µg/L or mg/L)
Qw=permitted effluent flow(cfs,match s7Q 10)
s7Q 10=summer low flow used to protect aquatic life from chronic toxicity and
human health through the consumption of water,fish,and shellfish from
noncarcinogens (cfs)
* Discussions are on-going with EPA on how best to address background
concentrations
Flows other than s7Q 10 may be incorporated as applicable:
IQ 10=used in the equation to protect aquatic life from acute toxicity
QA=used in the equation to protect human health through the consumption
of water,fish, and shellfish from carcinogens
30Q2=used in the equation to protect aesthetic quality
6. The permit writer enters the most recent 2-3 years of effluent data for each pollutant of concern.
Data entered must have been taken within four and one-half years prior to the date of the permit
application(40 CFR 122.21). The RPA spreadsheet estimates the 95th percentile upper
concentration of each pollutant. The Predicted Max concentrations are compared to the Total
allowable concentrations to determine if a permit limit is necessary. If the predicted max exceeds
the acute or chronic Total allowable concentrations,the discharge is considered to show reasonable
potential to violate the water quality standard, and a permit limit(Total allowable concentration)is
included in the permit in accordance with the U.S. EPA Technical Support Document for Water
Quality-Based Toxics Control published in 1991.
7. When appropriate,permit writers develop facility specific compliance schedules in accordance with
the EPA Headquarters Memo dated May 10,2007 from James Hanlon to Alexis Strauss on 40 CFR
122.47 Compliance Schedule Requirements.
8. The Total Chromium NC WQS was removed and replaced with trivalent chromium and hexavalent
chromium Water Quality Standards.As a cost savings measure,total chromium data results may be
used as a conservative surrogate in cases where there are no analytical results based on chromium
III or VI. In these cases,the projected maximum concentration(95th%)for total chromium will be
compared against water quality standards for chromium III and chromium VI.

Re: Comments to Draft NPDES Permit NCO082970
CTI of North Carolina, Inc.
Ms. Thedford:
The following comments are being provided in response to the Draft NPDES Permit, NC0082970,
issued to the CTI of North Carolina, Inc. terminal in Wilmington.
Supplement to Permit Cover Sheet,#1 (page 2 of 17): To clarify this condition, boiler blowdown
includes steam condensate from traps on the steam circulation system.
Part 1.A.(1.) and Part 1.A.(2.), Total Suspended Solids (page 3 and 4 of 17): As stated in the
summary of changes for renewal, total suspended solids (TSS) needs to be removed from the
effluent limitations and monitoring requirement tables for Outfalls 001 and 003. TSS monitoring
is being discontinued because the receiving stream is not impaired for TSS.
Part 1.A.(1.), Methanol and BOD-S testing requirement (page 3 of 17): Due to a methanol
release that occurred on November 29, 2015, monitoring for methanol and BOD5 were added to
the monitoring requirements for Outfall 001 in the permit that became effective January 1, 2017.
There has been no monthly sample collected with detectable levels of methanol in Outfall 001
since February 2020. Results from the BOD5 analysis conducted over this same period also show
results well under the daily and monthly average maximum. There no longer exists a concern
with methanol being discharged. As such, we request that the methanol and BOD-5 testing
requirements be removed from the permit for Outfall 001.
Part 1.A.(1.), Benzene, Toluene, Ethyl Benzene and Xylene (page 3 of 17): Benzene, Toluene,
Ethyl Benzene and Xylene monthly results from Outfall 001 have been under the detection limit
since March 2018. Based on these monthly results, there is no reasonable potential for these
parameters to be discharged from this outfall. We request that these parameters be reduced in
monitoring frequency to semi-annual to match Outfall 003's monitoring requirements.

DocuSign Envelope ID:Al D7C99B-CD30-4912-9EA6-4CBED33E9C63
Part 1.A.(1.), Chronic WET Testing (page 3 of 17): WET testing for Outfall 001 was changed from
Acute WET testing to Chronic WET testing with the rationale that Outfall 001 is a complex waste
stream with continuous flow. Outfall 001 does not have continuous flow. The flow is episodic
and is largely dependent on rainfall. Therefore, based on the definition given, Outfall 001 should
continue with Acute WET testing.
Part 1.A.(1.)and Part 1.A.(2.) Footnotes,Turbidity(page 3 and 4 of 17): In footnote 4 for Outfall
001 and footnote 3 for Outfall 003, the turbidity limits are listed as 25 NTU. This is incorrect and
the limit should be listed as 50 NTU to reflect the change made to the turbidity limit. The footnote
should read, "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."
If you have any questions concerning this submittal, please contact me at 912-443-6645. We
would appreciate a response during the comment period, which would afford us the ability to
correct issues of concern before the permit is issued.

Dear Mr. Denard:
Please find attached NPDES Permit Renewal Application for the CTI of North Carolina, Inc.
terminal located at 1002 South Front Street, Wilmington. The terminal is a bulk liquid
petroleum/chemical storage terminal and has no refining or production capability. There have not
been any significant changes at the terminal since the last permit was issued.
Methanol monitoring was added to the 2017 permit as a result of a release that occurred in 2015.
Over the period,eriod Methanol has been nondetect except for 3 instances. In 2 of these cases,
p
BOD5 was also elevated. We request that Methanol be removed as a monitoring parameter and
allow BOD5 to be an indication of organic concentration in the effluent.
Please feel free to call me at [phone] with any questions you may have concerning this
