Subject: Issuance of NPDES Permit NCO082970
CTI of North Carolina, Inc.
Wilmington Terminal, PC-1
1002 S. Front St, Wilmington, NC 28401
New Hanover County
Director
The Division of Water Resources (the Division) hereby issues the attached NPDES permit for the subject
facility. This permit is issued 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.
The Division understands that you have made no significant changes to your facility since the last permit
renewal. We have made the following updates to your previous permit in the October 19, 2016 draft:
1. added updates to facility map including adjustment of coordinates to the outfalls
o Outfall 001 34e 13' 16", -77e 57' 03"
o Outfall003 34e 13' 20", -77e 57' 04"
2. added monthly effluent Turbidity monitoring for both outfalls including 25 NTU effluent limits
(both daily maximum & monthly average) for salt water along with Footnote 4 regarding receiving
stream turbidity [NCAC 02B. 0220 (19)]
3. added monthly average limit of 30 mg/L for Total Suspend Solids (TSS) for both outfalls
4. the Oil & Grease (O&G) parameter code [00556] remains the same for submitting DMR/eDMR, but
uses test EPA method 1664 (SGT-HEM) with results in mg/L
5. changed toxicity monitoring to Acute Whole Effluent Toxicity (WET) testing [TGE3E], Pass/Fail,
Static 2- hr, Mysid Shrimp (Mysidapsis bahia) with no significant mortality @ 90% which is the
appropriate WET test for saltwater [Condition A. (5.)]
6. inserted Footnote 7 which addresses WET test failures
7. added electronic reporting of discharge monitoring reports (eDMR) in Section A. (6.)
8. added monthly methanol monitoring to Outfall 001 due to the release
9. added monthly BOD, 5-day (20eC) with a daily maximum limit of 45 mg/L and monthly average
limit of 30 mg/L to Outfall 001 due to the methanol release.

Changes made since the October 19, 2016 draft permit include the following:
10. removed footnote regarding samples being collected concurrently with annual Acute Toxicity.
Regarding comments on the October 19, 2016 draft permit please note the following:
The phase "each subsequent discharge" means the next discharge event. At a minimum, the permit
requires that the monitoring frequency be conducted monthly upon failure of a toxicity sample
[Section A. (5.)]. However, it is understood that due to conditions resulting in "no flow" such as
drought that a subsequent discharge may be greater than a month from the initial failure. "No flow"
may be entered on the DMR for months in which no flow occurs as discussed in Footnote 2. Once a
failure occurs, toxicity monitoring reverts to Section A. (5.) with monthly monitoring until a test is
passed and quarterly monitoring for the duration of the permit cycle (second paragraph in bold text).
The permittee may petition to relax monitoring, as data may warrant with the permit renewal
application or submit a major permit modification application. Currently, annual monitoring for this
permit is conditional unless failure occurs.
Typos were corrected for the letter "T" that was inadvertently deleted from the word "There" in the
first condition footnote and the omitted word "unless" in the last footnote condition for both outfall
effluent pages.
Provided that the Permittee can demonstrate with sufficient data to the Division that this facility
no longer has an issue with methanol in the effluent or the potential for another release of
methanol, monitoring for methanol and BOD-5 can be modified by application. A reduction in
monitoring frequency or removal of monitoring maybe petitioned for by submitting an
application for a major permit modification or by request upon the next permit renewal.
Starting December 21, 2016, federal regulations require electronic submittal of all discharge monitoring
reports (DMRs) and specify that, if a state does not establish a system to receive such submittals, then
permittees must submit DMRs electronically to the Environmental Protection Agency (EPA). The final
NPDES Electronic Reporting Rule was adopted and became effective on December 21, 2015.
The requirement to begin reporting discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application has been added to your final
NPDES permit. [See Special Condition A. (6.)] For information on eDMR, registering for eDMR and
obtaining an eDMR user account, please visit the following web page:

1. Starting on December 21, 2016, begin submitting Discharge Monitoring Reports electronically using NC
DWR's eDMR application system. See Condition A. (6).
2. Each discharge event shall be monitored for Flow volume and 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
Page 3 of 10

NPDES Permit NCO082970
4) calculate flow based on total rainfall per unit area draining to the outfall using the Rational Method
[see formula, Section A. (3)].
3. Where possible, the grab sample for Oil & Grease should be skimmed from the water surface of a quiescent
(calm water) zone.
4. Turbidity — Effluent turbidity shall not cause receiving -stream turbidity to exceed 25 NTU. If background
turbidity naturally exceeds 25 NTU, the effluent shall not cause background turbidity to increase. Any
discharge exceeding this permit limit will require sufficient instream sampling (upstream and/or downstream)
to verify compliance (effluent vs. background). [NCAC 02B. 0220(19)]
5. All practical quantitation limits (PQL) must be sufficiently sensitive considering the respective water quality
standard for each parameter [see Part II. Section D. (4.)].
6. 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.
7. If Acute WET -test fails [TGE3E], Mysid Shrimp (Mysidopsis bahia), the Permittee shall test each subsequent
discharge event until testing indicates "pass," after which Quarterly monitoring shall resume in accord with
Section A. (5.). If after a subsequent five (5) consecutive Quarterly events, WET results demonstrate no
toxicity (i.e., "pass"), the Permittee may petition the Division to relax monitoring, as data may warrant.
WET -test samples shall be collected concurrently with other POC samples, as appropriate to monitoring
frequencies.
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, toluene concentration tests less than 370 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.

NPDES Permit NCO082970
A. (5.) ACUTE TOXICITY PASS/FAIL LIMIT (QUARTERLY)
[15A NCAC 02B .0200 et seq.]
The pem- ittee 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.
Should any single quarterly monitoring indicate a f= 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:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dosetresponse 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 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, 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. 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
Page 7 of 10

NPDES Permit NCO082970
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.
A. (6.) 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 and specify that, if a state does not establish a system to receive such submittals, then permittees
must submit monitoring data and reports electronically to the Environmental Protection Agency (EPA).
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.)
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)
Signatory Requirements
Reporting
Records Retention
Monitoring Reports
1. Reporting Requirements (Supersedes Section D. (2.) and Section E. (5.) (a)1
Effective December 21, 2016, 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 DENR / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Page 8 of 10

NPDES Permit NC0082970
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: http://www2.gpa. ov/compliance/final-national pollutant-
dise-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
Page 9 of 10

h
NPDES Permit NC0082970
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:
bftp://d2g.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)1
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part H,
Section B. (I 1.)(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:

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.)l

Facility Summary:
1. This facility is a 100% industrial (flow <1 MGD) Surface -Water Pollution Control System for
stormwater, diesel tank bottoms, boiler blowdown and groundwater remediation system in proximity to
above -ground storage tanks (ASTs), surface bulk -storage of petroleum hydrocarbon fuels in excess of
one million gallons, utilizing;
a treatment system for each of two (2) discharges [Outfalls 001 & 003] consisting of the following
components;
o gravity type oil/water separator
o mechanical skimmers
o product holding/storage tanks
a 0.014 MGD groundwater treatment system combined with Outfall 001 consisting of the following
components;
o an oil/water separator
o air stripper
o particulate filters
o activated carbon
For Renewal: This permit reflects discharge at Outfall 001. DWR updated the following:
1. added updates to facility map including adjustment of coordinates to the outfalls
o Outfall 001 34' 13' 16", -770 57' 03"
Fact Sheet
Renewal 2016 -- NPDES Pennit NCO082970
Page 1

o Outfall 003 34° 13' 20". -77" 57' 04"
2. added monthly effluent Turbidity monitoring for both outfalls including 25 NTU effluent limits (both
daily maximum & monthly average) for salt water along with Footnote 4 regarding receiving stream
turbidity [NCAC 02B. 0220 (19)]
3. added monthly average limit of 30 mg/L for Total Suspend Solids (TSS) for both outfalls
4. the Oil & Grease (O&G) parameter code [00556] remains the same for submitting DMR/eDMR, but
uses test EPA method 1664 (SGT-HEM) with results in mg/L
5. changed toxicity monitoring to Acute Whole Effluent Toxicity (WET) testing [TGE3E], Pass/Fail,
Static 2- hr, Mysid Shrimp (Mysidopsis bahia) with no significant mortality @ 90% which is the
appropriate WET test for saltwater [Condition A. (5.)]
6. inserted Footnote 7 which addresses WET test failures
7. added electronic reporting of discharge monitoring reports (eDMR) in Section A. (6.)
8. added monthly methanol monitoring to Outfall 001 due to the release
9. added monthly BOD, 5-day (20°C) with a daily maximum limit of 45 mg/L and monthly average limit
of 30 mg/L to Outfall 001 due to the methanol release.
Changes made since the October 19, 2016 draft permit include the following:
10. removed footnote regarding samples being collected concurrently with annual Acute Toxicity.
Regarding comments on the October 19, 2016 draft permit please note the following:
The phase "each subsequent discharge" means the next discharge event. At a minunum, the permit
requires that the monitoring frequency be conducted monthly upon failure of a toxicity sample
[Section A. (5.)]. However, it is understood that due to conditions resulting in "no flow" such as
drought that a subsequent discharge may be greater than a month from the initial failure. "No flow"
may be entered on the DMR for months in which no flow occurs as discussed in Footnote 2. Once a
failure occurs, toxicity monitoring reverts to Section A. (5.) with monthly monitoring until a test is
passed and quarterly monitoring for the duration of the permit cycle (second paragraph in bold text).
The permittee may petition to relax monitoring, as data may warrant with the permit renewal
application or submit a major permit modification application. Currently, annual monitoring for this
permit is conditional unless failure occurs.
Typos were corrected for the letter "T" that was inadvertently deleted from the word "There" in the
first condition footnote and the omitted word "unless" in the last footnote condition for both outfall
effluent pages.
Provided that the Permittee can demonstrate with sufficient data to the Division that this facility no
longer has an issue with methanol in the effluent or the potential for another release of methanol,
monitoring for methanol and BOD-5 can be modified by application. A reduction in monitoring
frequency or removal of monitoring maybe petitioned for by submitting an application for a major
permit modification or by request upon the next permit renewal.
BOD5 and Methanol Monitoring: The application cover letter for this permit indicated that April 2016
sampling resulted in a COD result of 51 mg/L and a BOD5 result of 13 mg/L. Monthly monitoring is
added for BOD, 5-day (20°C) with a daily maximum limit of 45 mg/L and monthly average limit of 30
mg/L to Outfall 001 due to the methanol release. Since Methanol does not have a standard for salt water,
the parameter will be inserted as monitoring only.
Stream: The stream segment is listed as [ 18-(71)a3] Impaired (Cat 5) for Dissolved Oxygen (5 mg/l, AL,
SW), Fish Tissue Mercury (Nar, FC, NC) and Copper (3 µg/1, AL, SW) in the 2014 Integrated Report
305(b) list.

*Primary Nursery Areas (PNA), as defined by the Marine Fisheries Commission, are those areas in the
estuarine system where initial post -larval development takes place. These areas are usually located in the
uppermost sections of a system where populations are uniformly very early juveniles. The Division of
Marine Fisheries is responsible for preserving, protecting and developing Primary Nursery Areas for
commercially important finfish and shellfish.
RPA: The need for toxicant limits is based upon a demonstration of reasonable potential to exceed water
quality standards, a statistical evaluation that is conducted during every permit renewal utilizing the most
recent effluent data for each outfall. The RPA is conducted in accordance with 40 CFR 122.44 (d) (i). The
NC RPA procedure utilizes the following: 1) 95% Confidence Level/95% Probability; 2) assumption of
zero background; 3) use of V2 detection limit for "less than" values; and 4) streamflows used for dilution
consideration based on 15A NCAC 2B.0206. Effective April 6, 2016, NC began implementation of
dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of
Instream Dissolved Metals Standards, dated June 10, 2016.
A reasonable potential analysis was conducted on effluent toxicant data collected between Jan 2012 -
Jun2016. Pollutants of concern included toxicants with positive detections and associated water quality
standards/criteria. Based on this analysis, the following permitting actions are proposed for this permit:
• Monitoring Only. The following parameters will receive a monitor -only requirement since they did
not demonstrate reasonable potential to exceed applicable water quality standards/criteria, but
remain a parameter of concern in accordance with current permitting strategy: Toluene (Outfall
001), Ethylbenzene (Outfall 001) and Naphthalene (Outfalls 001 & 003 )

Whole Effluent Toxicity OWM: This facility is stormwater-only [episodic/simple wastestream]. Currently
WET testing is Acute WET [TAE6C] Fathead Minnow (Pimephales promelas), 24-hr definitive, LC-50
>100%. Acute test history demonstrates no toxicity issues [See attached data summary].
Acute WET testing is deemed appropriate to evaluate end -of -pipe short-term impacts of episodic
discharges. Chronic WET testing is applied to onsite groundwater remediation because these wastestreams
are deemed complex and can be non -episodic. These facilities typically discharge under zero flow
conditions (IWC=100%), therefore WET testing is conducted @ 90% effluent concentration. [REF Memo:
Coleen Sullins, DWQ, 1999].
For renewal quarterly toxicity monitoring to Acute Whole Effluent Toxicity (WET) testing [TGE3E],
Pass/Fail, Static 2- hr, Mysid Shrimp (Mysidopsis Bahia) with no significant mortality @ 90% for January,
April, July, October which is appropriate for saltwater. The following Footnote 6 was inserted: If Acute
Whole Effluent Toxicity (WET) test fails [TGE3E], the Permittee shall test each subsequent discharge event
until testing indicates "pass," after which Quarterly monitoring shall resume in accord with Section A. (5.).
If after a subsequent five (5) consecutive Quarterly events, WET results demonstrate no toxicity (i.e.,
"pass"), the Permittee may petition the Division to relax monitoring, as data may warrant. WET -test
samples shall be collected concurrently with other POC samples, as appropriate to monitoring frequencies.

Re: Comments to Draft NPDES Permit NCO082970
CTI of North Carolina, Inc.
Dear Mr. Denard:
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 10): 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.), Acute WET Testing (page 3 of 10 and 5 of 10): As
specified in these sections, Acute Wet Testing is to be completed annually. However,
Part 1.A.(5.) (page 7 of 10) states that the permittee shall conduct acute toxicity tests
on a quarterly basis. Please verify that the annual sampling frequency, which is the
same frequency we currently have, is correct
Further, Part 1.A.(1.), Footnote 7 (page 4 of 10) and Part 1.A.(2.), Footnote 7 (page 6
of 10) states that if the Acute Wet -test fails, the permittee shall test each "subsequent
discharge event' until testing indicates pass, after which quarterly monitoring shall
resume in accordance with Part 1.A.(5.). Can you please define "subsequent discharge
event". We assume this means the subsequent quarterly sampling events. Further,
these footnotes reference that we will resume quarterly monitoring, however, Part
1.A.(1.) and Part 1.A.(2.) both indicate this sampling is to be conducted annually.
Part 1.A.(1.), Footnote 5 (page 4 of 10) and Part 1.A.(2.), Footnote 5 (page 5 of
10): This footnote is not clearly written. The parameters referenced in Footnote 5
are to be sampled on a monthly basis, whereas WET -test samples are collected
1002 South Front Street, Wilmington, NC 28401 Office: 910.762.2271 Fax: [phone]
colonialgroupi nc.com

r
annually. To clarify this condition, the first sentence of Footnote 5 could be written
as follows, "WET -test samples shall be collected concurrently with a monthly
sampling event."
Part 1.A.(1.), Conditions (page 4 of 10) and Part 1.A.(2.), Conditions (page 6
of 10): The third bullet appears to be missing wording. The following is possible
wording which clarifies the condition; "Hydrostatic Tank Testing: the Permittee shall
discharge no tank solids, no tank bottom -water, no tank rag -layer, no tank (or pipe)
contents, unless the toluene concentration tests less than 370 ug/l."
Part 1.A.(2.), Conditions (page 6 of 10): The first bullet appears to be missing the
word "There" at the beginning of the sentence.
Part 1.A.(1.) Methanol and BOD-5 testing requirement (page 3 of 10): Methanol
and BOD-5 testing is to be completed monthly. This requirement is from the permit
application dated June 8, 2016, in which we discuss the methanol spill which occurred
onsite in late 2015. In the permit application, we requested approval to discharge
stormwater containing what we believed would become deminimus levels of
methanol through our NPDES outfall (001). In the 5 months that have passed since
the permit application was submitted, the stormwater being collected onsite no
longer contains methanol. Attached are the 2 most recent sample results collected
from the 001 outfall collected on August 31 and November 8. Both results show non -
detect for methanol and the November 8 result shows a BOD-5 result of 7 mg/l. We
believe there no longer exists a concern with methanol being discharged. As such, we
are requesting that this requirement be removed from the permit.
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.
Sincerely,
Tom Dolan

Subject: CTI (NC0082970) Issues
Hey Tom, Jim Gregson wanted me to send you an email concerning an issue in the Wilmington region. CTI of North
Carolina is a petroleum/fuel terminal along the Cape Fear River, they had a methanol spill a couple of weeks ago from a
tank overflow that did not reach surface waters. This site has an NPDES permit (NC0082970) with 2 outfall locations,
one being a groundwater remediation outfall and the other being a stormwater outfall from a tank farm area. They have
been working with UST and Inactive Hazardous Sites on this spill so far.
I spoke with Jim Baker from Colonial Group Inc. yesterday, it seems that they are developing a plan for disposing of the
collected wastewater from the event. They have approximately 30,000-40,000 gallons of collected water with up to
2,000 mg/I methanol in a storage tank(s) that they are planning to haul away for treatment. What they are working on is
how to handle water collected in the future that may have much lower concentrations of methanol in it from
surrounding soil contamination. Mr. Baker indicated they are considering processing this water with low methanol
concentration through their existing groundwater remediation system and discharging it. I reminded Mr. Baker that
since an event occurred that may effect the quality and quantity of the wastewater generated at the site, additional
sampling may be involved with this scenario.
After speaking with Jim Gregson this morning, we were wondering if this is something that could be conducted under
their existing permit if we added some additional sampling parameters and frequencies? Let us know what you think.
Thanks

Re: NPDES Permit Renewal Application Water Quality
CTI of North Carolina, Inc. — Wilmington Terminal Permitting Section
Existing NPDES Permit No. NCO082970
New Hanover County
Dear Mr. Thedford,
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, except for a methanol
release which occurred on November 29, 2015. As a result of the release, we have stormwater
which has contacted the contaminated soil in the tank fields and contains very low levels of
methanol. We request approval to discharge stormwater containing what we believe will become
deminimus levels of methanol through our existing NPDES outfall (001).
Analysis from stormwater collected in late April indicates methanol levels of 4 mg/l. Further, the
COD level of the late April sample was 51 mg/I and the BOD5 level was 13 mg/l. These levels
have decreased substantially since the November 2015 release. To date we have pumped all
contaminated stormwater to an onsite holding tank and intend to have that transported and treated
offsite. As we continue to receive methanol contaminated stormwater at diminishing
concentrations, the cost per unit will become extraordinarily high.
We understand that a discharge limit might be 30 mg/1 BOD5 as a daily average. Considering our
current BOD5 level of 13 mg/1 which is steadily decreasing, would we be allowed to discharge
stormwater collected at that concentration?
The facility does not generate any sludge from the wastewater treatment process and thus
does not maintain a sludge management plan.
