Section 1. Facility Activities and Process:
The Port of Wilmington is a shipping port that performs import/export of containers, breakbulk, and
bulk materials, ocean vessel docking, loading/unloading, and associated activities. The site contains a
hazardous waste storage area and numerous ASTs containing gasoline, diesel fuel, motor oil,
transmission oil, hydraulic fluid, used oil, lubrication oil, parts cleaning fluid, breakbulk storage, and
receiving hoppers and conveyers. Per information provided with the 2021 permit renewal application,
logs are no longer stored, chipped, debarked or stuffed into containers onsite. There are no open piles of
bulk material being stored outside and if any material is outside or returns in the future, the piles are
required to be fully covered except to load the material into trucks. Two large domes, a truck and rail
unloading facility, and a conveyor system for the storage and export of wood pellets have been installed.
These areas are all indoors or protected from the elements.
Per the 2007 SWPPP, the site consists of undeveloped vegetative areas or gravel storage areas. A small
portion of the northeastern corner of the site drains into Greenfield Creek through a drainage swale.
Approximately 160 acres off site also drain into the drainage swale. Material handling and storage
activities can be classified as one of four categories: container storage, open break bulk storage, open
bulk storage, and enclosed warehouse storage. Cargo shipped in containers is intended for transport by
truck and rail and is stored on paved areas at the port for pickup by truck, rail, or ship. The containers
remain closed throughout the storage and handling process and the contents are not exposed to
stormwater. Cargo shipped in bulk and/or breakbulk form is unloaded and stored inside or on paved or
gravel open storage areas. The material exposed to stormwater throughout its storage period may include
metals, scrap metal, vehicles, etc. Breakbulk material is stored in enclosed warehouses and may consist
of paper products, agriculture products, equipment, etc. All bulk material (except woodchips and salt) is
stored inside. The Port leases space within the terminal to various tenants. Per an email dated 10/2/2012,
Outfalls 103, 902, 1001, 1001A1, 1304, 1704, 2006, and 2501 are tidally affected.
Page 1 of 10

Per the 2016 permit renewal fact sheet, wood products, logs, and woodchips became the prevalent
commodity stored outdoors, and two 4+million gallon ASTs for urea ammonium nitrate (UAN liquid
fertilizer) were installed. Total ammonia and nitrate+nitrite monitoring were added only for SW200.
Vessel and truck loading/unloading systems were fully contained.

Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES regulations define
stormwater discharge associated with industrial activity in 40 CFR §122.26 (b)(14) as: "the discharge
from any conveyance that is used for collecting and conveying storm water and that is directly related to
Page 2 of 10

manufacturing,processing or raw materials storage areas at an industrial plant. The term does not
include discharges from facilities or activities excluded from the NPDES program under this part 122.
For the categories of industries identified in this section, the term includes, but is not limited to, storm
water [sic] discharges from industrial plant yards; immediate access roads and rail lines used or traveled
by carriers of raw materials, manufactured products, waste material, or byproducts used or created by
the facility; material handling sites; refuse sites; sites used for the application or disposal of process
waste waters (as defined at part 401 of this chapter); sites used for the storage and maintenance of
material handling equipment; sites used for residual treatment, storage, or disposal; shipping and
receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and
intermediate and final products; and areas where industrial activity has taken place in the past and
significant materials remain and are exposed to storm water. For the purposes of this paragraph, material
handling activities include storage, loading and unloading, transportation, or conveyance of any raw
material, intermediate product, final product, byproduct or waste product. The term excludes areas
located on plant lands separate from the plant's industrial activities, such as office buildings and
accompanying parking lots as long as the drainage from the excluded areas is not mixed with storm
water [sic] drained from the above described areas."
Section 2. Monitoring Information and Compliance History:
• Facility uses sample locations rather than sampling at each outfall
o Per an email dated 8/29/2023, the outfalls are all under the dock and not accessible except
by boat and at low tide, samples cannot reasonably be taken at the outfall itself, so the
sample locations were set up as close to the outfalls as possible
• June 2017 to May 2023,benchmarks exceeded for:
o SW103: BOD Ix, COD 4x, TSS 4x
o SW200: COD 8x, TSS Ix
o SW206: BOD 2x, COD 4x, TSS 5x, Total Lead 2x, pH Ix
o SW606: COD Ix, TSS 4x, Total Lead Ix,pH Ix
o SW1001: COD 3x, TSS 5x, Total Lead Ix
o SW1304: TSS 5x
o SW 1704: BOD 2x, COD 4x, TSS 5x
o SW2006: COD 4x, TSS 4x
o SW2012: BOD Ix, COD 2x, TSS 3x, pH Ix
o SW2501: COD Ix, TSS 4x, Total Lead Ix
o KM North: BOD Ix, COD 2x, TSS 2x,pH Ix
o KM South: No monitoring data
o Additional exceedances for COD and TSS for outfalls 1704*, 200A1, and 2012
o No monitoring data provided for first half of 2019
• New motor oil usage: DMR should report actual number of gallons used (DMRs provided only
state "> 55 gal/mo")
• During previous permit cycle, tidal conditions were not reported with DMRs as required by the
previously issued permit
• Tiered response not followed for benchmark exceedances
o Semi-annual monitoring maintained despite numerous benchmark exceedances at
multiple outfalls
• Per the August 2023 inspection report: Compilation of the sampling data shows that further
evaluation is needed. The port has not conducted tier response to benchmark exceedances.
Biggest concern is the woodchip storage area. Greater attention to housekeeping and keeping
Page 3 of 10

chips inside the containment. The port has moved to increased container storage, less bulk
storage.
o WiRO follow email (dated 8/9/2023): The facility contact was very resistant to compiling
the data. WiRO staff inquired about what Tier the port is on for each location, and facility
contact gave a flippant answer that everything is on Tier two. Further questioning was not
pursued even though WiRO staff sure they have not followed the Tier protocols. More
needs to be done to show which tier they are in.
• Per the July 2012 inspection report:
o To alleviate the problem concerning missed opportunities for sampling due to rain events
occurring within 72 hours of a qualifying rain event, WiRO supports the collection of
samples within 72 hours of a qualifying rain event provided the previous rain event was
monitored(inches fallen) and documented and provided the previous rain event was not
of sufficient volume to result in the site being flushed prior to sampling.
o Outfall 1304 does not include an industrial area(consists of NC State Ports Authority
Office area on Barnett Blvd and parking area). The only industrial activity for 1304 is
overseen by Air Quality for an area where aerosol fumigation is taking place for
containers. WiRO supports the elimination of analytical requirements for this outfall.
o Outfall 1704 consistently reflects high COD due to debarking operations in the vicinity.
Debarking operations are consistently generating an extremely poor quality stormwater
discharge that has the characteristics of wastewater rather than impacted stormwater.

Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for June 2017 to May 2023. Quantitative sampling included pH, TSS, BOD, COD, total lead,
ammonia nitrogen, nitrate+nitrite, O&G, and new motor oil usage.
Parameters are based on potential pollutants in the drainage area, sampling results, and in some cases,
dependent upon future activities (e.g., ash removal through the drainage area). Below is a table of the
proposed monitoring for each outfall at the Port of Wilmington site.

Stormwater Benchmarks and Tiered Response: Rather than limits,North Carolina NPDES
Stormwater permits contain benchmark concentrations. Stormwater benchmarks are numerical action
levels for stormwater monitoring. Benchmarks are not effluent limits, and benchmark exceedances are
not permit violations. Benchmarks provide facilities a tool for assessing the significance of pollutants in
stormwater discharges and the effectiveness of best management practices (BMPs). Benchmark
concentrations are intended as guidelines for the facility's development and implementation of the
Stormwater Pollution Prevention Plan(SWPPP).
Page 7 of 10

Benchmark exceedances require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater BMPs in a tiered program. The permit establishes a
tiered approach to specify actions the permittee must take in response to analytical results above
benchmark concentrations. The tiered structure of the permit provides the permittee and DEMLR wide
flexibility to address issues that may arise with one or more parameters and/or outfalls.
Metals benchmarks are calculated to mimic acute water quality standards and with the guidance of
DWR. NC DWR follows established federal procedures for calculating acute standards when developing
the benchmarks. Just like the acute standards, metals benchmarks normally reflect one half of the
calculated Final Acute Value (the "1/2 FAV"). In most cases, translation into total recoverable values is
based on an assumed hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L.
Acute standards protect aquatic life from negative impacts of short-term exposure to higher levels of
chemicals where the discharge enters a waterbody. The Stormwater Permitting Program applies this
approach because of the ephemeral nature of rainfall events.
The Division may evaluate results to determine if a smaller suite of parameters for some outfalls is
adequate to characterize potential pollution or BMP effectiveness. For example, one or more metals or
other parameters may serve as an adequate tracer for the presence of ash pollution during disturbance or
ash removal in specific drainage areas at this site. For parameters that do not have a stormwater
benchmark, the Division may develop a benchmark value if appropriate toxicity data become available
or if rising trends in concentrations suggest a persistent source.
A summary of the benchmarks in the draft permit, and their basis, is below:
Parameter Benchmark Basis
Total Suspended 50 mg/L National Urban Runoff Program(NURP) Study, 1983
Solids TSS
H 6.8 s.u. —8.5 NC Water Quality Standard(Range)
p S.U.

COD - No saltwater benchmark; Monitor only
Total Nitrogen - No saltwater benchmark; Monitor only
Ammonia Nitrogen - No saltwater benchmark; Monitor only
Summer
Ammonia Nitrogen - No saltwater benchmark; Monitor only
Winter
Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the EPA and NC's
pollution prevention approach to stormwater permitting. The Division's maintains that implementation
of Best Management Practices (BMPs) and traditional stormwater management practices that control the
source of pollutants meets the definition of Best Available Technology (BAT) and Best Conventional
Pollutant Control Technology(BCT). The permit conditions are not numeric effluent limitations but are
designed to be flexible requirements for implementing site-specific plans to minimize and control
pollutants in stormwater discharges associated with the industrial activity. Title 40 Code of Federal
Page 8 of 10

Regulations (CFR) §122.44(k)(2) authorizes the use of BMPs in lieu of numeric effluent limitations in
NPDES permits when the agency finds numeric effluent limitations to be infeasible. The agency may
also impose BMP requirements which are "reasonably necessary" to carry out the purposes of the Act
under the authority of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included
under the authority of both of these regulatory provisions. In essence, the pollution prevention and BMP
requirements operate as limitations on effluent discharges that reflect the application of BAT/BCT.
Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee to propose an
alternative monitoring plan for approval by the Region:
• Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances,
exercise the option of contacting the DEMLR Regional Engineer as provided below in Tier
Three. The Regional Engineer may direct the response actions on the part of the permittee as
provided in Tier Three, including reduced or additional sampling parameters or frequency.
• If pursuing the alternative above after two consecutive exceedances, the permittee may propose
an alternative monitoring plan for approval by the Regional Engineer.
The permit therefore allows the permittee to petition the Regional Office for monitoring changes sooner
than Tier Three (upon any four benchmark exceedances) and gives guidance on one option to take. For
example, the permittee may request that mercury only be monitored semi-annually under the tiers, or
that only parameters over the benchmark be monitored more frequently. In this way, changes to the
monitoring scheme for any outfall could be handled outside of a permit modification.
Other Proposed Requirements:
• It is standard for Stormwater Pollution Prevention Plan(SWPPP)requirements to include an
annual certification that stormwater outfalls have been evaluated for the presence of non-
stormwater discharges, and if any are identified, how those discharges are permitted or otherwise
authorized.
• Requirement to submit a request for permit modification if the facility identifies or creates any
new outfalls, removes outfalls, or alters any drainage area that changes potential pollutants.
• The Division expects the permittee to apply best professional judgment and consider the safety
of its personnel in fulfilling sampling obligations under the permit.
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). If a
state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the EPA.
• Quarterly QualitativeNisual Monitoring to assure regular observation of outfalls throughout
year.
Section 4. Changes from previous permit to draft:
• Monitoring increased from semi-annually to quarterly for all parameters (qualitative and
quantitative)
• "No discharge" clarifications made
• Feasibility study requirement removed per updated stormwater program requirements
• eDMR requirement added
• Boilerplate language moved into body of the permit; boilerplate no longer attached
• Outfall-specific monitoring been implemented to reflect industrial activity and potential
pollutants specific to each discharge area

• Monitoring for nitrate+nitrite replaced by total nitrogen for outfall SW206
• Benchmarks updated for parameters per guidance from DWR Standards group on stormwater
benchmarks
o pH and lead benchmarks updated to saltwater benchmarks
o BOD, COD, and ammonia nitrogen benchmarks removed as there are no saltwater
benchmarks
Section 5. Changes from draft to final:
• None

RE: NCS000174; NCS000174
Dear Brianna Young:
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, and/or conservation/managed areas within the proposed project
boundary. These results are presented in the attached 'Documented Occurrences' tables and map.
The attached 'Potential Occurrences' table summarizes rare species and natural communities that
have been documented within a one-mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one-mile
radius of the project area, if any, are also included in this report.
If a Federally-listed species is documented within the project area or indicated within a one-mile
radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service
(USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here:
https://www.fws.gov/offices/Di rectory_/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
Also please note that the NC Natural Heritage Program may follow this letter with additional
correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Land and Water Fund
easement, or an occurrence of a Federally-listed species is documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact Rodney A. Butler at rod ney.butler(c)ncdcr.gov or 919-707-8603.

Permit: NCS000174 Owner-Facility:North Carolina State Ports Authority
Inspection Date: 08/03/2023 Inspection Type:Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
Met with Todd Walton, representing the Port of Wilmington. Discussed oproblems with the permit and if there is anything
that needs to be altered. Discussed sampling data. Discussed the basic operations of the port.
Complilation of the sampling data shows that further evaluation is needed. The port has not conducted tier response to
benchmark exceedances.
Biggest concern is the woodchip storage area.Greater attention to housekeeping and keeping chips inside the containment.
The port has moved to increased container storage, less bulk storage. Overall, not much has changed.

Brianna,
Here is the info you requested. Note that 1001 and 1001A both drain to outfall 1000.
I mentioned KMS1 and KMN1 for Kinder Morgan locations. Feel free to use those or make up new ones.
Kinder Morgan is a liquid tank farm that is surrounded by dyke walls. All of their products are stored in tanks and no
exposure to the environment occurs.
MHC info will be to you by the end of the week or next week.

I apologize for the back and forth. Based on information provided,there are 23 outfalls identified (not including the KM
outfalls), but only 12 sampling locations. Can you confirm which outfalls are associated with which sampling location? Or
of the identified outfalls, are only 12 are sampled?

In addition, please provide a description of industrial activity in the KM North and KM South drainage areas, as I did not

Hi Brianna,
So SW103, SW206, SW606, SW1001, SW1304, SW1704, SW2006, SW2012, SW2501, KM North, KM South are all
sample locations, not outfalls.
The outfalls are 100, 200,300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800,
1900, 2000, 2300, 2400, 2500 and have drainage areas associated with them. You requested "Description of
industrial activity in each drainage area" so the list has the activities that are taking place in that drainage
area. The outfalls are all under the dock and not accessible except by boat and at low tide,samples cannot reasonably
be taken at the outfall itself, so the sample locations were set up as close to the outfalls as possible.
I attached a map that should help you understand.

I am fine with KMS1 and KMN1 if you are.

Hello Todd,
After reviewing all the information provided, I have a few follow-up questions.
Information previously provided indicated the facility has the following outfalls:
SW103, SW20, SW206, SW606, SW1001, SW1304,SW1704, SW2006, SW2012, SW2501, KM North, KM South
The information you provided in your email below stated the following drainage areas:
100, 200, 300,400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2300,
2400, 2500
Please confirm which drainage areas go to which outfalls. In addition, provide a desired outfall number for KM North and
KM South.The eDMR reporting database requires numerical outfall numbers, so KM North and KM South must be
assigned a numerical number in addition to their text name. Please let me know if you have any questions.

Subject: RE: NCS000174 outfalls
Good afternoon Todd,
I have updated the monitoring required for the outfalls. As I stated in a previous email, a monitoring suspension was
previously added for SDO 01A1, however, it was made active for 6/1/2023 for our system to be able to handle it. It will
appear in the drop down for any reports created for months before June 2023, so you may get warnings that data is
missing when you try to submit the data, but this will not prevent you from submitting the report. Please let me know if
you have any other question or problems.
Thank you,

Subject: NCS000174 outfalls
Good morning,
As we discussed on the phone, below is a list of the outfalls currently in our database. It appears placeholders were put
in for the coordinates as all are the same. Please provide the correct outfall coordinates for each outfall so that this
information can be updated. Once I have this information, I can verify/correct the monitoring for each outfall based on
the current permit.

Todd was very resistant to compiling the data. I inquired about what tier the port is on for each location. He gave a
flippant answer that everything is on tier two. I did not pursue this line of questions even though I am sure that he has
not followed the tier protocols. I quickly compiled some of the data, but more needs to be done to show which tier they
are in.

Good afternoon,
The Division of Energy, Mineral, and Land Resources (DEMLR) Stormwater Permitting Program
acknowledges receipt of your renewal application for coverage under NPDES Permit Number NCS000174.
2

Please continue to comply with all conditions and monitoring requirements in your current NPDES stormwater
permit. As long as you have submitted a complete renewal request package and maintain compliance with those
permit conditions, stormwater discharges from this facility are authorized by that permit until the Division
issues a renewal permit or notifies you of an alternative action.
I am working on renewing the individual stormwater permit for the Port of Wilmington (NC S000174). I need
additional information in order to 1) confirm that the information I have is correct and 2)make sure the permit
adequately serves the needs of the facility. Please provide the following:
• Description of industrial activity occurring and chemicals stored onsite;
• Description of industrial activity in each drainage area;
• SIC (NAICS) code;
• An electronic spreadsheet summarizing all of the monitoring data that has been collected since the
effective date of the current permit;
• Verification that the information in the renewal application is still complete and correct; and
• An explanation of any operational changes since the renewal application was submitted.
Enter your stormwater permit number into the Stormwater Permit Summary Report and you will see a form that
includes the address of the facility,contact information for the permit, and the regulated stormwater outfall(s)for the
facility. Please review the facility information to make sure it is correct. Information can be updated using the links
provided below,where applicable:
• Facility/Company name or ownership: Name/Ownership Change Form
• Owner Affiliation (Legally responsible person; i.e., someone with the company who is designated to
represent the company per signatory requirements or another authorized representative): Permit Contact
Update Request Form
• Delegation of Signature Authority (DOSA): Permit Contact Update Request Form
• Billing contact: Permit Contact Update Request Form
• Permit contact: Permit Contact Update Request Form
• Facility contact: Permit Contact Update Request Form
• Facility address only: Email Bethanyy og ulias
• Stormwater outfall information: Email Bethany Georgoulias
• Visit the eDMR Six Steps website and complete Steps 1 and 2.
• Pay outstanding permit fees: Stormwater ePayment website
Once I have the above listed information, I can continue my review. You will receive a draft permit for a 30-day
comment period. During this time we will be able to address any comments or concerns you have. During the
same 30-day period, the draft will be sent to a Regional Office staff member for review as well as out to public
notice. Once all comments and concerns are addressed, you may be issued a final permit.
Please contact me if you have any questions.
Thank you,
Brianna Young, MS (she/her)

Summary of best management practices- Port of Wilmington (POW)
All tenants and POW departments located on the Port facility are required to fill out monthly
housekeeping forms after performing an inspection of their leased areas. Weekly and daily visual
inspections are performed by the POW environmental department and deficiencies are noted and
corrected immediately. When outdoor storage piles are present,they are required to be covered at all
times except when loading into trucks. Contracts with safety clean and noble oil are maintained to
dispose of any waste products in a swift,efficient, and environmentally friendly manner. Catlin
engineering is under contract to do annual inspections and interviews in order to update both the
required stormwater pollution prevent plan and best management practices manuals.
Pictures are included for some of the BMP's here at the POW.

Significant Changes to Industrial Activities—Port of Wilmington
Logs are no longer stored, chipped, debarked or stuffed into containers onsite. There are no open piles
of bulk material being stored outside and if any material is outside or returns in the future the piles are
required to be fully covered except to load the material into trucks.
Two large domes, a truck and rail unloading facility and a conveyor system for the storage and export of
wood pellets has been installed. These areas are all indoors or protected from the elements.
