Section 1. Facility Activities and Process:
The SePRO Research&Technology Campus is a pesticide formulation, agriculture, and research facility.
Two main product types are produced at the facility: copper-based algaecides and herbicides and
fluridone based herbicides. The copper-based herbicides and algaecides are produced by raw copper
material being conveyed into a reactor and mixed with amine-based chelators and water. Fluridone
based herbicides are produced by fluridone being poured into a diked mixing tank, ground in a liquid
state, then mixed with surfactants and thickeners. The sealed containers are transported off site. The site
also has laboratory activities (for scientific studies and lab assays), a research pond system for testing
chemicals, and row crop production. The pond system is in a grid network where plants are grown and
developed products are tested and interconnected with pipes and can adjust water level within the pond
system. Lower ponds in the grid have water dumped that was produced in the laboratory process.
Per the permit renewal application, the site contains copper as copper sulfate, basic copper carbonate,
and ammonia based chelated copper within outfalls 1 and 2 watershed and an ethylene diamine tank in
outfall 1 watershed.
Since the last permit renewal, the facility has installed rock water breaks in ditches,peat moss was
placed in the last rock water break before entering the main drainage ditch, beaver activity in the
drainage ditches around outfalls 4 and 5 was eliminated, and the truck loading dock was moved from
outside to under a covered building.
Per information in the permit file history:

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
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
Page 2 of 9

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:
• April 2019 to December 2023, benchmarks exceeded for:
o SWOOI: Ammonia nitrogen Ix, TN Ix, TSS 6x, aluminum 24x, copper 34x, zinc Ix,pH
max exceeded Ix
o SW002: TSS IOx, aluminum 27x, copper 42x, pH min not reached I
o SW003: TSS 5x, aluminum 27x, cadmium 2x, copper 17x, zinc Ix, pH min not
reached 1 x
o SW004: TSS 3x, aluminum 6x, cadmium 2x, copper 33x, zinc 12x, pH min not
reached 1 x
o SW005: Aluminum Ix, cadmium Ix, copper Ix, zinc Ix
• O&G only sampled two times (4/2019 and 6/2023)
• Spill occurred June 2021 of 15 gallons of Captain algaecide
• Per information in the permit file history, in 2015/2016 there were issues at the location due to
this unpermitted treatment system and DWR issued NOVs and took enforcement actions. This
led to a settlement agreement that required the facility to obtain coverage under the stormwater
permit.
• Per the March 2024 inspection report, the facility was deemed not compliant:
o Chemicals stored onsite not in secondary containment (either indoors or outdoors) and
have the potential to be exposed to stormwater
■ "The large quantities of chemicals stored on site should be located within
secondary containment or otherwise kept in accordance with your permit."
o SWPPP not complete
o Employees have not been trained
o Inspection program is lacking
Threatened/Endangered Species:
In the nearby vicinity there are threatened/endangered species including the Yellow Lampmussel
(Lampsilis cariosa;NC status: E),Neuse River Waterdog (Necturus lewisi;NC status: T; Federal status:
T), Eastern Lampmussel (Lampsilis radiata;NC status: T), Carolina Madtom(Noturus furiosus;NC
status: E; Federal status: E), and Triangle Floater(Alasmidonta undulata;NC status: T). Additional
species of concern include the Eastern Big-Eared Bat (Corynorhinus rafinesquii macrotis;NC status:
SC) and Roanoke Slabshell (Elliptio roanokensis;NC status: SC).
Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for April 2019 to December 2023. Quantitative sampling included pH, TSS, ammonia
nitrogen, TKN,NO2+NO3, total phosphorus, chloride, aluminum, arsenic, cadmium, calcium, copper,
lead, manganese, magnesium, nickel,potassium, sodium, zinc, and hardness.
Page 3 of 9

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 SePRO Campus 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).
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:

Copper Total 10 /L Acute Aquatic Criterion, 1/2 FAV
Potassium Total 17.14 mg/L 1/2 FAV
Zinc Total 126 /L Acute Aquatic Criterion, 1/2 FAV
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
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.
Page 6 of 9

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:
• Regulatory citations added
• 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
• Annual online SWPPP certification requirement removed per updated stormwater program
requirements
• eDMR requirement updated
• 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 TKN and NO2+NO3 has been replaced by Total Nitrogen
• Monitoring removed for total manganese removed as there are no surface water quality standards
or stormwater benchmarks
• Monitoring removed for total arsenic, total lead, and total nickel as all monitoring data was
below benchmarks (and nearly all data below detection levels) for previous permit cycle
• Monitoring removed for calcium, chloride, magnesium, and sodium as the reported values were
well below benchmarks and industrial processes do not use these pollutants (therefore no
discharge potential due to industrial activity)
• BMP condition added as Appendix Abased on comments from March 2024 inspection report
• Monitoring for BOD and COD added due to the type of materials kept onsite and type of
industrial activity occurring
• Footnote added for total hardness monitoring
• Benchmarks updated for parameters per guidance from DWR Standards group

Section 5. Changes from draft to final:
• None
Section 6. Discussions with the Facility and Regional Office:
• Initial contact with facility: 1/10/2024
• Initial contact with Regional Office: 1/9/2024
• Draft sent to CO peer review: N/A
• Draft sent to Regional Office: 4/3/2024
• Final permit sent for supervisor signature: 8/23/2024
Section 7. Comments received on draft permit:
• Maria Dunn (NCWRC; via email 4/12/2024): NCWRC has reviewed the permit modifications
for SePRO Research and Technology in Nash County and does not have comment on the
modifications to existing permit NC0000594. The modifications should aid in the monitoring of
the discharge and therefore provide a better understanding of potential impacts to receiving
waters and wildlife resources, including threatened and endangered species present in the area.
Improved monitoring may give better understanding of harmful discharge components that may
need to be addressed at a later date.
• Joe Armstrong (SePRO Corporation; via email 4/26/2024):
o We are asking for clarification on the language in Parts D-2 (b) and D-5 (a). Specifically,
we are seeking clarification if Tier status is determined for individual parameters or for
outfall sites. For example, if tier status is determined for individual parameters, is it
possible to sample on a quarterly basis for parameters where we have not observed an
exceedance and on a monthly basis for parameters that are in Tier Two or Tier Three
status?
■ DEMLR response: If a parameter exceeds its benchmark, all parameters at that
outfall will go into Tier I status. If the same parameter exceeds its benchmark
twice in a row, all parameters at that outfall will go into Tier 2 status. If the same
parameter exceeds its benchmark four times in any five (5)year period, all
parameters at that outfall will go into Tier 3 status.
o We request that the benchmark for total copper be increased to 20 µg/L from the stated
10 µg/L (listed in Part D-2, Table 1). We believe the current benchmark is much lower
than the background amount of copper in most soils in our area of 17 ppm or 17,000 µg
Cu/kg (Buchman 2008), making it challenging to achieve levels below the benchmark.
Additionally,background copper concentrations in aquatic ecosystems can be as high as
30 µg/L (Flemming and Treavors 1989).
■ DEMLR response: Benchmarks are based on water quality standards and cannot
be adjusted. Therefore the benchmark for total copper shall remain at 10 µg/L.
o The permit is clear in Part D-3 (d) and(e)that stormwater samples should be collected
during the facility's normal operating hours (business hours for the SePRO Research&
Technology Campus are Monday - Friday from 8 am - 5 pm, excluding major holidays).
However, stormwater samples submitted for biological oxygen demand(BOD) analysis
have a hold time of only 48 hours. As such, samples cannot be collected on a Friday for
BOD analysis since laboratories are not open on Saturday or Sunday to accept samples.
Page 8 of 9

Therefore, we request that language be included in the permit to remove the requirement
for BOD testing or, if the requirement cannot be removed, to allow for exemption from
BOD analysis and reporting if a rainfall event occurs on a Friday and samples cannot be
delivered to the laboratory within the recommended holding time of 48 hours.
■ DEMLR response: Samples for BOD are required to be collected as stated in the
permit. Language shall not be added to the permit allowing omission of BOD
monitoring.
o There is a small typographical error in the second sentence of the first paragraph on page
12. The word"is" should be changed to "its."
■ DEMLR response: The error has been corrected.

Thank you for sending the draft NPDES Permit NCS000594 received via email on April 3, 2024
for the SePRO Research & Technology Campus near Whitakers in Nash County, North Carolina.
We have reviewed the draft permit and have some edits to request and questions for clarification.
We are happy to meet virtually or in-person to further discuss these items.
• We are asking for clarification on the language in Parts D-2 (b) and D-5 (a). Specifically,
we are seeking clarification if Tier status is determined for individual parameters or for
outfall sites. For example, if tier status is determined for individual parameters, is it

exceedance and on a monthly basis for parameters that are in Tier Two or Tier Three
status?
• We request that the benchmark for total copper be increased to 20 µg/L from the stated
10 µg/L (listed in Part D-2, Table 1). We believe the current benchmark is much lower
than the background amount of copper in most soils in our area of 17 ppm or 17,000 µg
Cu/kg (Buchman 2008), making it challenging to achieve levels below the benchmark.

Good morning Briana.
NCWRC has reviewed the permit modifications for SePRO Research and Technology in Nash County and does not have
comment on the modifications to existing permit NC0000594.The modifications should aid in the monitoring of the
discharge and therefore provide a better understanding of potential impacts to receiving waters and wildlife resources,
including threatened and endangered species present in the area. Improved monitoring may give better understanding
of harmful discharge components that may need to be addressed at a later date.
NCWRC has reviewed the permit modifications for PCS Phosphate—Morehead City Bulk(Nutrien) in Carteret County
and does not have comment on the modifications to existing permit NC0000520.The modifications should better asses
the more marine conditions and aid in the monitoring of the discharge,thereby providing a better understanding of
potential impacts to receiving waters and wildlife resources, including threatened and endangered species present in
the area. Improved monitoring may give better understanding of harmful discharge components that may need to be
addressed at a later date.
Thank you for the opportunity to review and provide comment on these draft permits.

Here is the report for SePRO Research that I had questions about. My comments to you about the secondary
containment for chemical storage areas were asked because I'm not sure whether we require that of all facilities.
It certainly appears to me they should be according to our requirements, but I'm not sure if that's the norm. Please
add what you think is appropriate for the permit

Permit: NCS000594 Owner-Facility:Sepro Development Company III LLC
Inspection Date: 03/06/2024 Inspection Type:Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
I meet with Sam Mason Director of Manufacturing and Joe Armstrong Director of Research, Regulatory and Innovation and
they provided the documents and showed me around the facility and the following is what I found.
During the site visit I noted that chemicals, including Acetic Acid are being stored in an open shelter that has a high
exposure to stormwater. It was raining moderately during the inspection and the rain was easily reaching the stored
chemicals and the floor around the chemicals was wet from the rain as seen in the photos taken.
We viewed the areas inside where more of the chemicals were stored in poly tanks, woven sacks and drums.
There is a good amount of chemicals stored indoors next to doors and rollup doors were the chemicals can easily run
outdoors if there is a spill. Additionally the base of the building at the floor is not made to contain liquids.
There is a room where chemical samples are stored in an abundance of small containers that have no type of containment
protection.
There are used containers outside in the form of poly tanks, drums and aluminum containers that should be stored inside
There are wood pallets used to receive and haul chemicals stored outside that should be stored inside.
There is a diesel fuel tank and dispenser outside that does have a double walled tank but no shelter or containment for the
dispenser
There is a pipe inlet downhill from the open shelter chemical storage area that discharges in a field next to an onsite pond
with no type of protection or standard operating procedure for what to do if a chemical spill reaches it.
There is a roll-off container that is not covered and should be. When ever there is nothing actively being placed in the roll-off
container, it should be covered.
Documentation:
The site map needs to be reviewed and upgraded to include all the required information required by the permit
Provide a spill list that documents all spills, reportable or not, for the last (3)years
A study of the economic and technical feasibility of altering the facilities ongoing practices for managing, storing, handling
and transporting materials that are exposed to stormwater should be undertaken each year.
The large quantities of chemicals stored on site should be located within secondary containment or otherwise kept in
accordance with your permit***********
The secondary containment areas located outside have a secured valve to release accumulated water, but there is not
documentation of who or when stormwater was released from the containment area or how it was determined there were no
issues with the water being released.
The BMP summery couldn't be found and is required.A list of site structural and non structural BMP's should be kept on
site that is a written record of each BMP and of any changes made to BMP's and the rational for those changes.The BMP
summery should be reviewed and updated annually.
Preventive maintenance and good housekeeping program (PMGHP) is not addressed in the SP3. There is a single sentence
under PMGHP that talks about inspection of areas. There must be a healthy PMGHP put together and the facility
employees should be trained yearly.
Procedures should be developed for all duties on site that have the potential to contaminate stormwater such as: Draining
Page 2 of 4

Permit: NCS000594 Owner-Facility:Sepro Development Company III LLC
Inspection Date: 03/06/2024 Inspection Type:Compliance Evaluation Reason for Visit: Routine
secondary containment located outside. Who is qualified to drain secondary containment and the steps for doing that if
water is clean or contaminated, Cleaning out secondary containment inside and when its cleaned (if not daily) how its
cleaned-what's done with the cleaning materials and chemicals that are cleaned out Loading, unloading, staging and
moving chemicals around the site.
The employees have not been trained on stormwater management strategies. This includes:
Secondary containment requirements and records
Spill prevention and response procedures for all areas of the facility
Preventive maintenance and good housekeeping that is site specific
Facility inspections that identifies all areas of the site that should be inspected and what for
Sample procedures if staff take the samples
The inspection program is not site specific and doesn't include all areas of the site that should be inspected, nor what they
are inspecting for. Some areas should be inspected for spills, some for leaks and some areas should be inspected to be
sure materials are not being stored where they are not supposed to be. The roll-off should be inspected to insure it doesn't
have rust holes, drains or that the door is sealed properly.
The stormwater pollution prevention plan should be reviewed and dated each year

took a number of photos at the SePRO Research Facility which is up for renewal. I have concerns about the
chemicals stored under the open shelter with no secondary containment as well as the large quantity of chemicals
stored indoors with no secondary containment next to rollup doors.The shelter area drains to a pipe inlet that
drains toward an onsite pond which is a concern as well.There are empty and filled to varying levels of drums and
containers around the site that I think should be in secondary containment and there is the diesel tank with no
shelter that I think should at least be sheltered.What are your thoughts on the chemicals under the open shelter
and in quantity indoors and the diesel fueling area.

Please see attachments for the documents and electronic files you requested. We will send the hard copies shortly.
For a description of chemicals stored at the site see section 4.2 and 7.19 of form 2F. Note the industrial activity is at sites
001 and 002, where copper algaecides and herbicides and fluridone based herbicides are produced.That location would
have the typical chemicals used for formulating copper algaecides and fluridone based herbicides. Sites 003, 004, and
005 do not have what I would call industrial activity.The water shed in those sites has a laboratory,turf plots, 0.1 acre
ponds, and fields where we conduct research.
There has not been a change in operations at the facility since the renewal was submitted, so the renewal application is
still complete and correct.
Feel free to call me if you have questions, 252 301 7891.

Subject: Stormwater permit for SePRO Research &Technology Campus (NCS000594)
This message originated from outside your organization
Good morning,
I am working on renewing the individual stormwater permit for the SePRO Research & Technology Campus
(NCS000594). 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:
• Section 5.1 of EPA Form 2F was not signed;
• SWPPP Certification Form was signed by Ben Willis, who does not have permit signature authority.
The form must be signed by Joe Armstrong or someone who has been delegated permit signature
authority;
• Tables A, B, and C do not provide the maximum values. Please resubmit the tables with these values
populated;
• Table C does not have any data provided for outfall 005;
• Description of chemicals stored onsite;
• Description of industrial activity in each drainage area;
• 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 Bethany 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 ePgMent 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.

Chemical hygiene within the facility was increased. Specifically, spills were clean
immediately. Drip pans are used to collect any potential leaks when transferring materials.
Bulk sacks are bagged before removal from manufacturing buildings.
Outside of the manufacturing buildings rock water breaks were placed in the ditches to slow
overland flow of stormwater to reduce erosion potential. Also, peat moss was placed in the last
rock water break before entering the main drainage ditch to prevent non-rainwater materials
from going into the main drainage ditch.
The beaver activity in the drainage ditches around outfalls 4 and 5 were eliminated to prevent
degradation of culverts and allow flow to continue.
Some soil was removed from behind the research ponds and new grass was seeded with grass
and fertilized.

The truck loading dock was moved from outside to under a covered building.

Permit No.NCS000594
PART I INTRODUCTION
SECTION A: INDIVIDUAL PERMIT COVERAGE
During the period beginning on the effective date of the permit and lasting until expiration,
the permittee is authorized to discharge stormwater associated with industrial activity.
Such discharges shall be controlled,limited and monitored as specified in this permit.
If industrial materials and activities are not exposed to precipitation or runoff as described
in 40 CFR§122.26(g),the facility may qualify for a No Exposure Certification from NPDES
stormwater discharge permit requirements. Any owner or operator wishing to obtain a No
Exposure Certification must:
• Submit a No Exposure Certification Notice of Intent (NOI) form to the Division
of Energy, Mineral and Land Resources (Division)
• Receive approval by the Division,
• Maintain no exposure conditions unless authorized to discharge under a valid
NPDES stormwater permit,and
• Recertify the No Exposure Exclusion annually.
SECTION B: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked,the permittee is authorized to discharge
stormwater to the surface waters of North Carolina or separate storm sewer system that
has been adequately treated and managed in accordance with the terms and conditions of
this permit
Any other point source discharge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization,or
approval. The stormwater discharges allowed by this permit shall not cause or contribute
to violations of Water Quality Standards.
This permit does not relieve the permittee from responsibility for compliance with any
other applicable federal,state,or local law,rule,standard, ordinance, order,judgment,or
decree.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN (SWPPP)
The permittee shall develop and implement a Stormwater Pollution Prevention Plan
(SWPPP). The SWPPP shall be maintained on site unless exempted from this requirement
by the Division. The SWPPP is public information in accordance with Part III,Standard
Conditions, Section E,paragraph 3 of this permit. The SWPPP shall include,at a minimum,
the following items:
1. Site Overview. The Site Overview shall provide a description of the physical facility
and the potential pollutant sources that may be expected to contribute to
contamination of stormwater discharges. The Site Overview shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters;the name of the receiving waters to which the stormwater outfalls
discharge, or if the discharge is to a municipal separate storm sewer system,the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the points of stormwater discharge associated with industrial
activity. The general location map (or alternatively the site map) shall identify
whether any receiving waters are impaired (on the state's 303(d) list of impaired
waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are.
(b) A narrative description of storage practices,loading and unloading activities,
outdoor process areas,dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants that
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary;
the stormwater discharge outfalls; all on-site and adjacent surface waters and
wetlands; industrial activity areas (including storage of materials, disposal areas,
process areas, Ioading and unloading areas, and haul roads); site topography and
finished grade; all drainage features and structures; drainage area boundaries and
total contributing area for each outfall; direction of flow in each drainage area;
industrial activities occurring in each drainage area; buildings; stormwater Best
Management Practices (BMPs); and impervious surfaces. The site map must
indicate the percentage of each drainage area that is impervious, and the site map
must include a graphic scale indication and north arrow.
(d) A list of significant spills or leaks of pollutants during the previous three (3) years
and any corrective actions taken to mitigate spill impacts.
Page 3 of 28

Permit No.NCS000594
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The permittee shall re-certify annually that the
stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. The certification statement will be signed in accordance with the
requirements found in Part III,Standard Conditions,Section B, Paragraph 3.
2. Stormwater Management Strategy. The Stormwater Management Strategy shall
contain a narrative description of the materials management practices employed which
control or minimize the stormwater exposure of significant materials, including
structural and nonstructural measures. The Stormwater Management Strategy, at a
minimum,shall incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to rainfall and run-on flows. Wherever practical,the
permittee shall prevent exposure of all storage areas,material handling operations,
and manufacturing or fueling operations. In areas where elimination of exposure is
not practical,this review shall document the feasibility of diverting the stormwater
run-on away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amtount of Section 313
of Title III of the Superfund Amendments and Reauthorization Act (SARA)water
priority chemicals: and storage in any amount of hazardous substances, in order to
prevent leaks and spills from contaminating stormwater runoff. A table or summary
of all such tanks and stored materials and their associated secondary containment
areas shall be maintained. If the secondary containment devices are connected to
stormwater conveyance systems,the connection shall be controlled by manually
activated valves or other similar devices (which shall be secured closed with a
locking mechanism). Any stormwater that accumulates in the containment area
shall be at a minimum visually observed for color, foam,outfall staining,visible
sheens and dry weather flow,prior to release of the accumulated stormwater.
Accumulated stormwater shall be released if found to be uncontaminated by any
material. Records documenting the individual making the observation,the
description of the accumulated stormwater, and the date and time of the release
shall be kept for a period of five (5) years. For facilities subject to a federal oil Spill
Prevention, Control,and Countermeasure Plan (SPCC), any portion of the SPCC Plan
fully compliant with the requirements of this permit may be used to demonstrate
compliance with this permit. The Division may allow exceptions to secondary
containment requirements for mobile refuelers,as with the exemption provided by
amendments to federal SPCC regulations,as long as appropriate spill containment
and/or diversionary structures or equipment is used to prevent discharge to surface
waters. Exceptions do not apply to refuelers or other mobile tankage used primarily
as bulk liquid material storage in a fixed location in place of stationary containers.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs
Page 4 of 28

Permit No.NCS000594
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and on data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Procedures. The Spill Prevention and Response
Procedures (SPRP) shall incorporate an assessment of potential pollutant sources based
on a materials inventory of the facility. Facility personnel responsible for implementing
the SPRP shall be identified in a written list incorporated into the SPRP and signed and
dated by each individual acknowledging their responsibilities for the plan. A
responsible person shall be on-site at all times during facility operations that have
increased potential to contaminate stormwater runoff through spills or exposure of
materials associated with the facility operations. The SPRP must be site stormwater
specific. Therefore,an oil Spill Prevention Control and Countermeasure plan (SPCC)
may be a component of the SPRP,but may not be sufficient to completely address the
stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may
be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed and implemented.
The program shall address all stormwater control systems (if applicable), stormwater
discharge outfalls, all on-site and adjacent surface waters and wetlands,industrial
activity areas (including material storage areas, material handling areas, disposal areas,
process areas,loading and unloading areas, and haul roads), all drainage features and
structures,and existing structural BMPs. The program shall establish schedules of
inspections, maintenance,and housekeeping activities of stormwater control systems,
as well as facility equipment, facility areas, and facility systems that present a potential
for stormwater exposure or stormwater pollution where not already addressed under
another element of the SWPPP. Inspection of material handling areas and regular
cleaning schedules of these areas shall be incorporated into the program. Timely
compliance with the established schedules for inspections,maintenance, and
housekeeping shall be recorded and maintained in the SWPPP.
5. Facility inspections. Inspections of the facility and all stormwater systems shall occur
as part of the Preventative Maintenance and Good Housekeeping Program at a
minimum on a semi-annual schedule, once during the first half of the year (January to
June),and once during the second half(July to December),with at least 60 days
separating inspection dates (unless performed more frequently than semi-annually).
These facility inspections are different from,and in addition to,the stormwater
discharge characteristic monitoring at the outfalls required in Part II B and C of this
permit.
6. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill
response and cleanup, preventative maintenance activities,and for any of the facility's
operations that have the potential to contaminate stormwater runoff. The facility
Page 5 of 28

Permit No.NCS000594
personnel responsible for implementing the training shall be identified,and their
annual training shall be documented by the signature of each employee trained.
7. Responsible Party. The SWPPP shall identify a specific position or positions
responsible for the overall coordination,development,implementation, and revision of
the SWPPP. Responsibilities for all components of the SWPPP shall be documented and
position assignments provided.
8. SWPPP Amendment and Annual Update. The permittee shall amend the SWPPP
whenever there is a change in design, construction, operation,site drainage,
maintenance,or configuration of the physical features which may have a significant
effect on the potential for the discharge of pollutants to surface waters. All aspects of
the SWPPP shall be reviewed and updated on an annual basis. The annual update
shall include:
(a) an updated list of significant spills or leaks of pollutants for the previous three
(3) years,or the notation that no spills have occurred (element of the Site
uverview),-,
(b) a written re-ceri cation that the stormwater outfalls have been evaluated for
the presence of non st rmwater discharges (element of the Site Overview);
(c) a documented re-evaluad: n of the effectiveness of the on-site stormwater
BMPs (BMP of the Stormwater Management Strategy).
(d) a rc;,;ew an a" cQmn ins-on of s�ie analyacui uu benchmark values(if
applicable) over the past year, including a discussion ab k;'iered Response

The Director giay nofify the permittee when the SWrrP does not meet one or more of
the n-+inimum requirements of the permit Within 30 days of such notice,the permittee
shall submit a time schedule to the Director for modifying the SWPPP to meet minimum
requirements. The permittee shall provide certification in writing(in accordance with
Part III,Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
9. SWPPP Implementation. The permittee shall implement the SWPPP and all
appropriate BMPs consistent with the provisions of this permit, in order to control
contaminants entering surface waters via stormwater. Implementation of the SWPPP
shall include documentation of all monitoring, measurements,inspections, maintenance
activities,and training provided to employees,including the log of the sampling data
and of actions taken to implement BMPs associated with the industrial activities,
including vehicle maintenance activities. Such documentation shall be kept on-site for a
period of five (5) years and made available to the Division immediately upon request

Permit No.NCS000594
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1.
All analytical monitoring shall be performed during a measurable storm event at each
stormwater discharge outfall (SDO). Only SDOs discharging stormwater associated with
industrial activity must be sampled (See Definitions).
A measurable storm event is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a
shorter interval is representative for local storm events during the sampling period,and the
permittee obtains approval from the local DEMLR Regional Engineer. See Definitions.
The permittee shall compare monitoring results to the benchmark values in Table 1.
Exceedances of benchmark values require the permittee to increase monitoring, increase
management actions, increase record keeping,and/or install stormwater Best Management
Practices (BMPs) in a tiered program. See below the descriptions of Tier One,Tier Two,and
Tier Three response actions below. In the event that the Division releases the permittee from
continued monthly monitoring and reporting under Tier Two or Tier Three,the Division's
release letter may remain in effect through subsequent reissuance of this permit, unless the
release letter provides for other conditions or duration.
The benchmark values in Table 1 are not permit limits but should be used as guidelines for
implementation of the permittee's SWPPP. An exceedance of a stormwater benchmark
value is not a permit violation; however, failure to respond to the exceedance as outlined in
this permit is a violation of permit conditions.
Please note that the parameters in the last two rows in Table 1 (no-polar oil and grease and
new motor oil usage) are only required for outfalls that discharge runoff from vehicle or
equipment maintenance areas in which more than 55 gallons of new motor oil and/or
hydraulic oil per month is used when averaged over the calendar year.

1 Measurement Frequency: Twice per year(unless other provisions of this permit prompt monthly
sampling)during a measurable storm event,until either another permit is issued for this facility or
until this permit is revoked or rescinded. If the facility is monitoring monthly because of Tier Two or
Three response actions under the previous permit,the facility shall continue a monthly monitoring
and reporting schedule in Tier Two or Tier Three status until relieved by the provisions of this
permit or the Division.
2 Grab samples shall be collected within the first 30 minutes of discharge. When physical separation
between outfalls prevents collecting all samples within the first 30 minutes,sampling shall begin within
the first 30 minutes,and shall continue until completed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall(SDO)unless
representative outfall status(ROS)has been granted. A copy of the Division's letter granting ROS shall
be kept on site. Samples shall also be collected at an in-ditch monitoring point downstream of the
discharge from the facility's riser structure below the pond system.
4 For each sampled measureable storm event,the total precipitation must be recorded. An on-site rain
gauge is required. Where isolated sites are unmanned for extended periods of time,a local rain gauge
reading may be substituted for an on-site reading.
5 This parameter is only required for outfalls that discharge runoff from vehicle/equipment maintenance
areas in which more than 55 gallons of new motor oil per month is used when averaged over the
calendar year.
The permittee shall complete the analytical samplings in accordance with the schedule
specified below in Table 2,unless adverse weather conditions prevent sample collection
(see Adverse Weather in Definitions). Sampling is not required outside of the facility's
normal operating hours. A minimum of 60 days must separate Period 1 and Period 2
sample dates, unless monthly monitoring has been instituted under a "Tier Two"
response. Inability to sample because of adverse weather conditions must be documented
in the SWPPP and recorded on the DMR. The permittee must report the results from each
sample taken within the monitoring period (see Part III, Section E). However, for purposes
Page 8 of 28

Permit No.NCS000594
of benchmark comparison and Tiered response actions,the permittee shall use the
analytical results from the first sample with valid results within the monitoring period.

Period 1 January 1 June 30
Period 2 July 1 December 31
Footnotes:
1 Maintain semi-annual monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded. The permittee must submit an application for renewal of coverage
before the submittal deadline(180 days before expiration)to be considered for renewed coverage
under the permit. The permittee must continue analytical monitoring throughout the permit
renewal process,even if a renewal permit is not issued until after expiration of this permit.
2 If no discharge occurs during the sampling period,the permittee must submit a monitoring report
indicating"No Flow"or"No Discharge"within 30 days of the end of the sampling period.
3 Monitoring periods remain consistent through the permit term and through the renewal process.
Failure to monitor semi-annually per permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified time period. "No discharge' from an
outfall during a monitoring period does not constitute failure to monitor,as long as it is
properly recorded and reported.
Tier One
If:The first valid sampling results are above a benchmark value,or outside of the benchmark range,for any
parameter at any outfall;
Then:The permittee shall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving sampling
results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential,and select the specific feasible:source controls,operational controls,or physical
improvements to reduce concentrations of the parameters of concern,and/or to bring concentrations
within the benchmark range.
4. Implement the selected feasible actions within two months of the inspection.
5. Record each instance of a Tier One response in the SWPPP. Include the date and value of the benchmark
exceedance,the inspection date,the personnel conducting the inspection,the selected actions,and the
date the selected actions were implemented.
6. Note: Benchmark exceedances for a different parameter separately trigger a tiered response.
Page 9 of 28

Permit No.NCS000594
Tier Two
If:The first valid sampling results from two consecutive monitoring periods(omitting periods with no
discharge)are above the benchmark values,or outside of the benchmark range,for any specific parameter at
a specific discharge outfall;
Then:The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples. Monthly(analytical and qualitative) monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period,the permittee is required to submit a monthly
monitoring report indicating"No Flora'to comply with reporting requirements.
4. 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.
5. Maintain a record of the Tier Two response in the SWPPP.
6. Continue Tier Two response obligations throughout the permit renewal process.
- - -- - ----- - -- -- Tier Three
If:The valid sampling results required for the permit monitoring periods exceed the benchmark value,or
are outside the benchmark range,for any specific parameter at any specific outfall on four occasions,the
permittee shall notify the DEMLR Regional Engineer in writing within 30 days of receipt of the fourth
analytical results;
Then:The Division may but is not limited to:
• require that the permittee revise,increase,or decrease the monitoring and reporting frequency for
some or all of the parameters herein;
• require sampling of additional or substitute parameters;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize impacts on
receiving waters;
• require the permittee implement site modifications to qualify for a No Exposure Exclusion;
• require the permittee to continue Tier Three obligations through the permit renewal process.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the SWPPP and
identify new potential sources of stormwater pollution. Qualitative monitoring of
stormwater outfalls must be performed during a measurable storm event.
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed semi-annually
during required analytical monitoring events (unless the permittee is required to perform
further qualitative monitoring per the Qualitative Monitoring Response,below). Inability
to monitor because of adverse weather conditions must be documented in the SWPPP and
recorded on the Qualitative Monitoring Report form (see Adverse Weather in Definitions).
Page 10 of 28

Permit No.NCS000594
Only SDOs discharging stormwater associated with industrial activity must be monitored
(See Definitions).
In the event an atypical condition is noted at a stormwater discharge outfall,the permittee
shall document the suspected cause of the condition and any actions taken in response to
the discovery. This documentation will be maintained with the SWPPP.

2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(00)regardless of representative outfall status.
A minimum of 60 days must separate monitoring dates, unless additional sampling has
been instituted as part of other analytical monitoring requirements in this permit.
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are
ineffective, or that significant stormwater contamination is present,the permittee shall
investigate potential causes, evaluate the feasibility of corrective actions, and implement
those corrective actions within 60 days, per the Qualitative Monitoring Response, below.
A written record of the permittee's investigation, evaluation,and response actions shall be
kept in the SWPPP.
Page 11 of 28

Permit No.NCS000594
uali#ative Monitoring Response
Qualitative monitoring is for the purposes of evaluating SWPPP effectiveness, identifying new
potential sources of stormwater pollution, and prompting the permittee's response to pollution. If
the permittee repeatedly fails to respond effectively to correct problems identified by qualitative
monitoring, or if the discharge causes or contributes to a water quality standard violation, the
Division may but is not limited to:
• require that the permittee revise,increase,or decrease the monitoring frequency for some
or all parameters (analytical or qualitative)
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters;or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.
SECTION D: SPECIAL CONDITIONS
ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)]

When eDMR is initiated, 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 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 no later than 30 days from
the date the facility receives the sampling results from the laboratory.
2. 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.

PART II MONITORING, CONTROLS,AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN (SWPPP)
The permittee shall develop and implement a Stormwater Pollution Prevention Plan
(SWPPP). The SWPPP shall be maintained on site unless exempted from this requirement
by the Division. The SWPPP is public information in accordance with Part III,Standard
Conditions, Section E, paragraph 3 of this permit. The SWPPP shall include,at a minimum,
the following items:
1. Site Overview. The Site Overview shall provide a description of the physical facility
and the potential pollutant sources that may be expected to contribute to
contamination of stormwater discharges. The Site Overview shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters; the name of the receiving waters to which the stormwater outfalls
discharge, or if the discharge is to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the points of stormwater discharge associated with industrial
activity. The general location map (or alternatively the site map) shall identify
whether any receiving waters are impaired (on the state's 303(d) list of impaired
waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas,dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants that
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary;
the stormwater discharge outfalls; all on-site and adjacent surface waters and
wetlands; industrial activity areas (including storage of materials, disposal areas,
process areas,loading and unloading areas,and haul roads); site topography and
finished grade; all drainage features and structures; drainage area boundaries and
total contributing area for each outfall; direction of flow in each drainage area;
industrial activities occurring in each drainage area; buildings; stormwater Best
Management Practices (BMPs); and impervious surfaces. The site map must
indicate the percentage of each drainage area that is impervious,and the site map
must include a graphic scale indication and north arrow.
(d) A list of significant spills or leaks of pollutants during the previous three (3)years
and any corrective actions taken to mitigate spill impacts.
Page 3 of 28

Permit No.NCS000594
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The permittee shall re-certify annually that the
stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. The certification statement will be signed in accordance with the
requirements found in Part III, Standard Conditions,Section B, Paragraph 3.
2. Stormwater Management Strategy. The Stormwater Management Strategy shall
contain a narrative description of the materials management practices employed which
control or minimize the stormwater exposure of significant materials,including
structural and nonstructural measures. The Stormwater Management Strategy, at a
minimum,shall incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to rainfall and run-on flows. Wherever practical,the
permittee shall prevent exposure of all storage areas,material handling operations,
and manufacturing or fueling operations. In areas where elimination of exposure is
not practical,this review shall document the feasibility of diverting the stormwater
run-on away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section 313
of Title III of the Superfund Amendments and Reauthorization Act (SARA)water
priority chemicals: and storage in any amount of hazardous substances,in order to
prevent leaks and spills from contaminating stormwater runoff. A table or summary
of all such tanks and stored materials and their associated secondary containment
areas shall be maintained. If the secondary containment devices are connected to
stormwater conveyance systems,the connection shall be controlled by manually
activated valves or other similar devices (which shall be secured closed with a
locking mechanism). Any stormwater that accumulates in the containment area
shall be at a minimum visually observed for color,foam, outfall staining,visible
sheens and dry weather flow,prior to release of the accumulated stormwater.
Accumulated stormwater shall be released if found to be uncontaminated by any
material. Records documenting the individual making the observation, the
description of the accumulated stormwater, and the date and time of the release
shall be kept for a period of five (5) years. For facilities subject to a federal oil Spill
Prevention, Control,and Countermeasure Plan (SPCC), any portion of the SPCC Plan
fully compliant with the requirements of this permit may be used to demonstrate
compliance with this permit. The Division may allow exceptions to secondary
containment requirements for mobile refuelers,as with the exemption provided by
amendments to federal SPCC regulations,as long as appropriate spill containment
and/or diversionary structures or equipment is used to prevent discharge to surface
waters. Exceptions do not apply to refuelers or other mobile tankage used primarily
as bulk liquid material storage in a fixed location in place of stationary containers.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs
Page 4 of 28

Permit No.NCS000594
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and on data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Procedures. The Spill Prevention and Response
Procedures (SPRP) shall incorporate an assessment of potential pollutant sources based
on a materials inventory of the facility. Facility personnel responsible for implementing
the SPRP shall be identified in a written list incorporated into the SPRP and signed and
dated by each individual acknowledging their responsibilities for the plan. A
responsible person shall be on-site at all times during facility operations that have
increased potential to contaminate stormwater runoff through spills or exposure of
materials associated with the facility operations. The SPRP must be site stormwater
specific. Therefore,an oil Spill Prevention Control and Countermeasure plan (SPCC)
may be a component of the SPRP,but may not be sufficient to completely address the
stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may
be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed and implemented.
The program shall address all stormwater control systems (if applicable),stormwater
discharge outfalls, all on-site and adjacent surface waters and wetlands,industrial
activity areas (including material storage areas, material handling areas, disposal areas,
process areas,loading and unloading areas, and haul roads), all drainage features and
structures, and existing structural BMPs. The program shall establish schedules of
inspections, maintenance, and housekeeping activities of stormwater control systems,
as well as facility equipment,facility areas, and facility systems that present a potential
for stormwater exposure or stormwater pollution where not already addressed under
another element of the SWPPP. Inspection of material handling areas and regular
cleaning schedules of these areas shall be incorporated into the program. Timely
compliance with the established schedules for inspections,maintenance,and
housekeeping shall be recorded and maintained in the SWPPP.
S. Facility Inspections. Inspections of the facility and all stormwater systems shall occur
as part of the Preventative Maintenance and Good Housekeeping Program at a
minimum on a semi-annual schedule, once during the first half of the year(January to
June),and once during the second half(July to December),with at least 60 days
separating inspection dates (unless performed more frequently than semi-annually).
These facility inspections are different from,and in addition to,the stormwater
discharge characteristic monitoring at the outfalls required in Part II B and C of this
permit.
6. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill
response and cleanup, preventative maintenance activities,and for any of the facility's
operations that have the potential to contaminate stormwater runoff. The facility
Page 5 of 28

Permit No.NCS000594
personnel responsible for implementing the training shall be identified,and their
annual training shall be documented by the signature of each employee trained.
7. Responsible Party. The SWPPP shall identify a specific position or positions
responsible for the overall coordination,development, implementation,and revision of
the SWPPP. Responsibilities for all components of the SWPPP shall be documented and
position assignments provided.
8. SWPPP Amendment and Annual Update. The permittee shall amend the SWPPP
whenever there is a change in design, construction, operation, site drainage,
maintenance, or configuration of the physical features which may have a significant
effect on the potential for the discharge of pollutants to surface waters. All aspects of
the SWPPP shall be reviewed and updated on an annual basis.The annual update
shall include:
(a) an updated list of significant spills or leaks of pollutants for the previous three
(3) years, or the notation that no spills have occurred (element of the Site
Overview);
(b) a written re-certification that the stormwater outfalls have been evaluated for
the presence of non-stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on-site stormwater
BMPs (BMP Summary element of the Stormwater Management Strategy).
(d) a review and comparison of sample analytical data to benchmark values (if
applicable) over the past year,including a discussion about Tiered Response
status. The permittee shall use the Division's Annual Summary Data
Monitoring Report (DMR) form,available from the Stormwater Permitting
Program's website (See: https://deq.nc.gov/about/divisions/energy-mineral-land-
res ources/npdes-stormwater-individual).
The Director may notify the permittee when the SWPPP does not meet one or more of
the minimum requirements of the permit Within 30 days of such notice,the permittee
shall submit a time schedule to the Director for modifying the SWPPP to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions,Section B, Paragraph 3) to the Director that the changes
have been made.
9. SWPPP Implementation. The permittee shall implement the SWPPP and all
appropriate BMPs consistent with the provisions of this permit,in order to control
contaminants entering surface waters via stormwater. Implementation of the SWPPP
shall include documentation of all monitoring, measurements,inspections,maintenance
activities,and training provided to employees,including the log of the sampling data
and of actions taken to implement BMPs associated with the industrial activities,
including vehicle maintenance activities. Such documentation shall be kept on-site for a
period of five (5) years and made available to the Division immediately upon request.

Permit No.NCS000594
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1.
All analytical monitoring shall be performed during a measurable storm event at e r
stormwater discharge outfall (SDO). Only SDOs discharging stormwater associated with
industrial activity must be sampled (See Definitions).
A measurable storm event is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a
shorter interval is representative for local storm events during the sampling period,and the
permittee obtains approval from the local DEMLR Regional Engineer. See Definitions.
The permittee shall compare monitoring results to the benchmark values in Table 1.
Exceedances of benchmark values require the permittee to increase monitoring, increase
management actions, increase record keeping,and/or install stormwater Best Management
Practices (BMPs) in a tiered program. See below the descriptions of Tier One,Tier Two,and
Tier Three response actions below. In the event that the Division releases the permittee from
continued monthly monitoring and reporting under Tier Two or Tier Three,the Division's
release Ietter may remain in effect through subsequent reissuance of this permit, unless the
release letter provides for other conditions or duration.
The benchmark values in Table 1 are not permit limits but should be used as guidelines for
implementation of the permittee's SWPPP. An exceedance of a stormwater benchmark
value is not a permit violation; however,failure to respond to the exceedance as outlined in
this permit is a violation of permit conditions.
Please note that the parameters in the last two rows in Table 1 (no-polar oil and grease and
new motor oil usage) are only required for outfalls that discharge runoff from vehicle or
equipment maintenance areas in which more than 55 gallons of new motor oil and/or
hydraulic oil per month is used when averaged over the calendar year.

1 Measurement Frequency: Twice per year(unless other provisions of this permit prompt monthly
sampling)during a measurable storm event,until either another permit is issued for this facility or
until this permit is revoked or rescinded. If the facility is monitoring monthly because of Tier Two or
Three response actions under the previous permit,the facility shall continue a monthly monitoring
and reporting schedule in Tier Two or Tier Three status until relieved by the provisions of this
permit or the Division.
2 Grab samples shall be collected within the first 30 minutes of discharge. When physical separation
between outfalls prevents collecting all samples within the first 30 minutes,sampling shall begin within
the first 30 minutes,and shall continue until completed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall(SDO)unless
representative outfall status(ROS)has been granted. A copy of the Division's letter granting ROS shall
be kept on site. Samples shall also be collected at an in-ditch monitoring point downstream of the
discharge from the facility's riser structure below the pond system.
4 For each sampled measureable storm event,the total precipitation must be recorded. An on-site rain
gauge is required. Where isolated sites are unmanned for extended periods of time,a local rain gauge
reading may be substituted for an on-site reading.
5 This parameter is only required for outfalls that discharge runoff from vehicle/equipment maintenance
areas in which more than 55 gallons of new motor oil per month is used when averaged over the
calendar year.
The permittee shall complete the analytical samplings in accordance with the schedule
specified below in Table 2,unless adverse weather conditions prevent sample collection
(see Adverse Weather in Definitions). Sampling is not required outside of the facility's
normal operating hours. A minimum of 60 days must separate Period 1 and Period 2
sample dates, unless monthly monitoring has been instituted under a "Tier Two"
response. Inability to sample because of adverse weather conditions must be documented
in the SWPPP and recorded on the DMR. The permittee must report the results from each
sample taken within the monitoring period (see Part III,Section E). However, for purposes
Page 8 of 28

Permit No.NCS000594
of benchmark comparison and Tiered response actions,the permittee shall use the
analytical results from the first sample with valid results within the monitoring period.

Footnotes:
1 Maintain semi-annual monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded. The permittee must submit an application for renewal of coverage
before the submittal deadline(180 days before expiration)to be considered for renewed coverage
under the permit. The permittee must continue analytical monitoring throughout the permit
renewal process,even if a renewal permit is not issued until after expiration of this permit.
2 If no discharge occurs during the sampling period,the permittee must submit a monitoring report
indicating"No Flow"or"No Discharge"within 30 days of the end of the sampling period.
3 Monitoring periods remain consistent through the permit term and through the renewal process.
Failure to monitor semi-annually per permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified time period."No discharge' from an
outfall during a monitoring period does not constitute failure to monitor, as long as it is
properly recorded and reported.
Tier One
If:The first valid sampling results are above a benchmark value,or outside of the benchmark range,for any
parameter at any outfall;
Then:The permittee shall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving sampling
results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential,and select the specific feasible:source controls,operational controls,or physical
improvements to reduce concentrations of the parameters of concern,and/or to bring concentrations
within the benchmark range.
4. Implement the selected feasible actions within two months of the inspection.
S. Record each instance of a Tier One response in the SWPPP. Include the date and value of the benchmark
exceedance,the inspection date,the personnel conducting the inspection,the selected actions,and the
date the selected actions were implemented.
b. Note: Benchmark exceedances for a different parameter separately trigger a tiered response.
Page 9 of 28

Permit No.NCS000594
Tier Two
If:The first valid sampling results from two consecutive monitoring periods (omitting periods with no
discharge)are above the benchmark values, or outside of the benchmark range,for any specific parameter at
a specific discharge outfall;
Then:The permittee shall:
I. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples. Monthly(analytical and qualitative)monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period,the permittee is required to submit a monthly
monitoring report indicating"No Flow"to comply with reporting requirements.
4. 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.
S. Maintain a record of the Tier Two response in the SWPPP.
b. Continue Tier Two response obligations throughout the permit renewal process.
- _ Tier Three
If The valid sampling results required for the permit monitoring periods exceed the benchmark value,or
are outside the benchmark range,for any specific parameter at any specific outfall on four occasions,the
permittee shall notify the DEMLR Regional Engineer in writing within 30 days of receipt of the fourth
analytical results; - - --- -
Then:The Division may but is not limited to:
• require that the permittee revise,increase,or decrease the monitoring and reporting frequency for
some or all of the parameters herein;
• require sampling of additional or substitute parameters;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize impacts on
receiving waters;
• require the permittee implement site modifications to qualify for a No Exposure Exclusion;
• require the permittee to continue Tier Three obligations through the permit renewal process.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the SWPPP and
identify new potential sources of stormwater pollution. Qualitative monitoring of
stormwater outfalls must be performed during a measurable storm event.
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed semi-annually
during required analytical monitoring events (unless the permittee is required to perform
further qualitative monitoring per the Qualitative Monitoring Response,below). Inability
to monitor because of adverse weather conditions must be documented in the SWPPP and
recorded on the Qualitative Monitoring Report form (see Adverse Weather in Definitions).
Page 10 of 28

Permit No.NCS000594
Only SDOs discharging stormwater associated with industrial activity must be monitored
(See Definitions).
In the event an atypical condition is noted at a stormwater discharge outfall,the permittee
shall document the suspected cause of the condition and any actions taken in response to
the discovery. This documentation will be maintained with the SWPPP.

ual#ative Monitoring ReVonse
Qualitative monitoring is for the purposes of evaluating SWPPP effectiveness, identifying new
potential sources of stormwater pollution, and prompting the permittee's response to pollution. If
the permittee repeatedly fails to respond effectively to correct problems identified by qualitative
monitoring, or if the discharge causes or contributes to a water quality standard violation, the
Division may but is not limited to:
• require that the permittee revise,increase,or decrease the monitoring frequency for some
or all parameters(analytical or qualitative)
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters;or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.
SECTION D: SPECIAL CONDITIONS
ELECTRONIC REPORTING OF 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 III of this permit(Standard Conditions for NPDES Permits):
• Section B. (3.) Signatory Requirements
• Section D. (6.) Records Retention
• Section E. (1.) Discharge Monitoring Reports
• Section E. (2.) Submitting Reports
1. Reporting Requirements
[Supplements Section E. (1.) and Supersedes Section E. (2.11
When the Division's electronic reporting system is able to accept NPDES stormwater
permit monitoring data,the permittee shall report discharge monitoring data
electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR)
internet application. The Division will notify permittees when eDMR is ready to accept
stormwater monitoring data.
Until the Division's eDMR application is compliant with EPA's Cross-Media Electronic
Reporting Regulation (CROMERR),permittees will be required to submit discharge
monitoring data to the state electronically using eDMR and also 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:

When eDMR is initiated, 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 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 no later than 30 days from
the date the facility receives the sampling results from the laboratory.
2. 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.
