Section 1. Facility Activities and Process:
The Nucor Steel Hertford County facility recycles scrap steel, alloys, and other metals into specified
grades of steel cast into slabs and sheets. A 250-ton direct current electric arc furnace produces molten
steel from steel scrap. The molten steel is refined to produce specified grades of steel and then cast via a
water-cooled continuous slab caster. The slabs are reheated in a furnace and rolled into finished steel
plates of various dimensions. Plate steel that is produced is leveled, sheared, and shipped as discrete
plate via truck and rail car. The facility has vehicle maintenance and slag and mill scale processing. A
COa system is on the B1 pond and a sulfuric acid feed system on the Al pond to address pH issues. The
blast and paint line became operational December 2021, increasing operational capacity but did not
affect any stormwater ditches, basins, or ponds.
Per the July 2023 inspection report, stormwater runoff from processing areas is treated in(4)wet ponds
(A 1, A3, B 1, C 1) that drain into adjacent wetlands and natural drainage ways prior to entering the
Chowan River. The existing grassed swales, vegetated buffers and wet ponds were a part of the original
site design and were approved by State Stormwater Permit SW7990624.
Non-stormwater discharges include:
• Emergency fire-fighting activities and uncontaminated fire hydrant flushings. Water from fire
hydrants comes from groundwater wells. This discharge may be present in all drainage basins,
but most prevalent in Al and Bl drainage areas.
• Flush potable water lines to ensure proper sampling and maintenance in basins Al, A3, Bl, Cl,
and DI. ASK RO ABOUT THIS
Page 1 of 11

• Water from the routine external pressure washing of buildings (without detergents and other
chemicals) in basins Al, A3, B1, Cl, and DI.
• Uncontaminated air conditioner condensate, compressor condensate, steam condensate, and
condensate from the outside storage of refrigerated gases or liquids in basins Al, A3, B 1, Cl, and
DI.
• Basement sumps with uncontaminated water from foundation or footing drains in basins Bl and
Al.
• Water for dust suppression on roadways is taken from the Al stormwater pond and the Fire Loop
system which is supplied by groundwater. This discharge may be present in drainage basins
including Al, A3, Bl, Cl, D1, and D2.
• Cooling Tower Mist: Large, contact and noncontact cooling water towers in the Outfall Al
drainage basin, and two smaller cooling towers in the Bl drainage basin. The water used in the
towers is treated with various chemicals to improve and sustain cooling tower performance.
Deposition of cooling tower mist has been observed in the areas outside the cooling tower basins.
Changes since the last permit renewal include:
• Two (2)new stormwater drainage areas discovered.
• Blast and Paint Building Addition: building addition to the main shipping building to add a paint
line building. The main stormwater drainage area affected by this project was the B1 area.
• Trailer Yard: addition of three (3) small trailer yards. The main drainage areas affected by this
project were the B1 and Cl drainage areas.
• Air Separation Unit Building: new building to house Nucor's Air Separation Plant. The main
drainage area affected by this project was the Bl area.
• Mold and Segment Building: new building to house Nucor's Mold and Segment maintenance
activities. The main drainage areas affected by this project were the Al and A3 areas.

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
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 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for September 2016 to November 2022. Quantitative sampling included pH, TSS, O&G,
COD,Nitrate+Nitrite, total phosphorus, lead, zinc, magnesium, copper, mercury, and antimony.
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 Nucor Steel 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.
Page 7 of 11

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 100 mg/L National Urban Runoff Program(NURP) Study, 1983
Solids TSS
H 6 s.u. —9 s.u. NC Water Quality Standard(Range)

Lead(Total) 75 /L Acute Aquatic Criterion, '/2 FAV
Mercury(Total) 12 ng/L Chronic 02B standard
Zinc Total 126 /L Acute Aquatic Criterion, '/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
Page 8 of 11

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.
Mercury Monitoring Requirements: The proposed permit requires mercury to be measured in
stormwater samples by EPA Method 1631 E,which can detect levels as low as 0.5 ng/l. This requirement
is consistent with recent federal rule-making that requires NPDES permittees to monitor discharges with
sufficiently sensitive test procedures approved under 40 CFR §136. Modifications to 40 CFR §122.44(i)
require a method that has a minimum level (ML) at or below the effluent limit(not applicable here), or
the lowest minimum level (ML) of EPA approved analytical methods for the measured parameter. Based
on results, Method 1631E will be required to quantify levels in these discharges. NC DEMLR
understands that this method is more costly and requires a more intensive sampling protocol than most
other parameters, and that fish tissue sampling will be provided during the permit cycle. Therefore, no
benchmark applies that would trigger tiered response actions. Proposed permit provisions also allow the
permittee to use field blank and/or method blank concentrations to adjust reported mercury levels as
long as documented is submitted with the Data Monitoring Report DMR).
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.
Page 9 of 11

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 lead and zinc has been updated from total recoverable to total
• Monitoring for antimony and magnesium has been removed as they are not used, processed, or
stored onsite
• Monitoring for BOD added for outfalls SWO02 and SWO04 due to presence of railroad ties
stored in these drainage areas
• Monitoring for creosote added for outfalls SWO02 and SWO04 due to presence of creosote
railroad ties
• Monitoring for nitrate+nitrite replaced with total nitrogen in line with SW program changes
• Monitoring for nitrate-nitrite and total phosphorus removed for outfalls SWO02, SWO04, SW005,
and SWO06 as there are no industrial processes present with these pollutants of concern
• Monitoring for total hardness added for all outfalls where monitoring for hardness dependent
metals is required
• Benchmarks updated for parameters per guidance from DWR Standards group on stormwater
benchmarks
Section 5. Changes from draft to final:
• None

• Initial contact with facility: 3/23/2023
• Initial contact with Regional Office: 3/23/2023
• Draft sent to CO peer review: N/A
• Draft sent to Regional Office: 8/2/2023

Section 7. Comments received on draft permit:
• Michael Sitarski(permittee representative; via email to WaRO 8/29/2023 and 8/31/2023):
o Change#8 states, "Monitoring for creosote and BOD have been added for outfalls
SWO02 and SWO04 due to the storage of railroad ties." If Nucor removes the storage of
railroad ties, may we remove the requirement for creosote and BOD testing? Or will we
still have to test for it because of all the railroad ties in use around the site? If this is the
Page 10 of 11

case, there are railroad ties present around all our stormwater ponds, not just A3 and C 1.
We want to make sure we cover everything.
o Under section D-2: Baseline Sampling Benchmarks, in the footnotes section after Table 1
(page 14), when describing the industrial activity that takes place around the AI and B1
pond basins, cooling towers are mentioned. Is cooling tower mist being considered an
allowable non-stormwater discharge? In Part 4, page 1 of our old NPDES permit,
Cooling Towers are not included in the description.Nucor just wants to clarify this point
and determine that since cooling towers are mentioned in the new permit, the state has
recognized that mist can be an allowable non-stormwater discharge. Is this correct?
o Will the use of a tarp to cover the railroad ties be satisfactory with the state to consider
them"under cover?
• Varun Prakash (WaRO; via email 8/29/2023 and 9/5/2023):
o Does the presence of railroad ties and rail lines at the industrial facility always mandate
creosote monitoring? Or is there something specific about this site that triggered creosote
monitoring? During our other inspections, we have seen other sites with railroad ties
storage without creosote monitoring.
■ DEMLR Response: Since the facility mentioned there was a storage area for
railroad ties treated with creosote, that is why creosote monitoring was included.
If you have other sites with creosote-treated railroad ties that do not include
creosote monitoring,please let me know what those are. I am trying to capture
that information in permits as I renew them, but if I have missed any I would like
to know that. The presence of the railroad Lie storage area is also why BOD
monitoring is required in this permit. If they moved the railroad ❑es to under
cover or removed them from the site, BOD monitoring could be removed, but I
would keep creosote monitoring in for one permit cycle to make sure there is no
legacy contamination(monitoring could be removed in future permits).
o Also, what is the requirement regarding cooling tower mist? I understand EPA guidelines
allow incidental windblown mist from cooling towers that collects on rooftops, but not
intentional discharges from cooling towers.
hgps://www3.epa.goy/npdes/pubs/industrial_swppp guide.pdf
■ DEMLR Response: The cooling towers are mentioned solely because they are
present in the drainage area and incidental mist could occur. Cooling tower
blowdown is not allowed to be discharged under the stormwater permit.
o Does covering railroad ties with tarp is sufficient for removing BOD monitoring? Or does
it still count as `legacy contamination' for the next permit cycle?
■ DEMLR Response: BOD monitoring would not be a legacy pollutant, however,
the use of a tarp would not be sufficient cover to remove BOD monitoring from
the permit. Coverage would need to be to be a storm-resistant shelter.

Subject: RE: [External] Nucor Stormwater Draft Permit questions
Hello Varun,
See below for answers to your questions. Let me know if you need anything else.
Does the presence of railroad ties and rail lines at the industrial facility always mandate creosote monitoring?Or is
there something specific about this site that triggered creosote monitoring? During our other inspections,we have
seen other sites with railroad ties storage without creosote monitoring.
Since the facility mentioned there was a storage area for railroad ties treated with creosote,that is why creosote
monitoring was included. If you have other sites with creosote-treated railroad ties that do not include creosote
monitoring, please let me know what those are. I am trying to capture that information in permits as I renew them, but
if I have missed any I would like to know that.The presence of the railroad tie storage area is also why BOD monitoring is
3

required in this permit. If they moved the railroad ties to under cover or removed them from the site, BOD monitoring
could be removed, but I would keep creosote monitoring in for one permit cycle to make sure there is no legacy
contamination (monitoring could be removed in future permits).
Also,what is the requirement regarding cooling tower mist? I understand EPA guidelines allow incidental windblown
mist from cooling towers that collects on rooftops, but not intentional discharges from cooling towers.
The cooling towers are mentioned solely because they are present in the drainage area and incidental mist could occur.
Cooling tower blowdown is not allowed to be discharged under the stormwater permit.
Thank you,

Brianna,
We got some queries from Nucor as highlighted in the trailing email and thought we should touch base with you before
we responded.
Does the presence of railroad ties and rail lines at the industrial facility always mandate creosote monitoring? Or is there
something specific about this site that triggered creosote monitoring?
During our other inspections, we have seen other sites with railroad ties storage without creosote monitoring.

Good morning,Varun and Bill,
After reviewing the draft permit that was sent to us a few weeks ago,we had a couple of questions for you before the
final draft gets issued. In the draft permit cover letter that was sent by Brianna Young,the letter lists out 12 significant
changes from our current permit.
Change#8 states, "Monitoring for creosote and BOD have been added for outfalls SWO02 and SWO04 due to the storage
of railroad ties." If Nucor removes the storage of railroad ties, may we remove the requirement for creosote and BOD
testing? Or will we still have to test for it because of all the railroad ties in use around the site? If this is the case,there
are railroad ties present around all our stormwater ponds, not just A3 and C1. We want to make sure we cover
everything.
Under section D-2: Baseline Sampling Benchmarks, in the footnotes section after Table 1 (page 14),when describing the
industrial activity that takes place around the Al and 131 pond basins, cooling towers are mentioned. Is cooling tower
mist being considered an allowable non-stormwater discharge? In Part 4, page 1 of our old NPDES permit, Cooling
Towers are not included in the description. Nucor just wants to clarify this point and determine that since cooling
towers are mentioned in the new permit,the state has recognized that mist can be an allowable non-stormwater
discharge. Is this correct?
Thank you for your time to review our questions.

Permit: NCS000379 Owner-Facility:Nucor Steel
Inspection Date: 07/19/2023 Inspection Type:Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
Inspection was conducted on 7/19/2023. Met with Molly Miller, Environmental Engineer([e-mail], M:
252-356-3795 ) , Michael Sitarski, Environmental Engineer, Environmental Engineer([e-mail], M:
252-377-7189), Christine Ebert, EHS Supervisor, ([e-mail], phone: [phone]). Nucor- Hertford
County facility recycles scrap steel, alloys, and other metals that are refined into specified grades of steel cast into slabs
and sheets. Nucor has a fully implemented Stormwater Management Plan (SWMP) including a site plan showing process
areas, drainage basins, stormwater control measures (SCMs), and stormwater discharge outfalls (SDOs). The SWMP is
updated annually and all records appear to be in good order.
Stormwater runoff from processing areas is treated in(4)wet ponds (Al, A3, B1, Cl)that drain into adjacent wetlands and
natural drainage ways prior to entering the Chowan River. The existing grassed swales,vegetated buffers and wet ponds
were apart of the original site design and were approved by a State Stormwater Permit(see SW7990624) . In general, the
wet ponds are reasonably well maintained. The following observations/comments are provided :
1. Pond Cl: slopes are stable &vegetation is well established; outlet structure with riser boards in good condition. Pond C!
discharges to an adjacent, well-established, constructed wetland area.
2. Pond B1: some of the swale slopes adjacent to the Oxygen Plant are void of vegetative cover& under repair; inspect
outlet structure and remove excess sediment deposits &vegetation as needed; inspect slopes &vegetated buffer along
northern perimeter of pond, repair as needed and maintain.
3. Pond Al: generally well maintained; need to repair&establish vegetation along north perimeter slope.
4. Pond A3: generally well maintained; water level approx. 15-inches below normal pool elev.
5. The dock area is located at the end of Port Rd &adjacent to the Chowan River. Stormwater is captured by perimeter curb
and routed to a collection sump/pit system with dual, float-controlled pumps. One of the sump pumps was out of service for
repairs; the other pump was operating, but with significant leakage back into the pit. Continuous maintenance of this sump
collecton/pump system is crucial to prevent stormwater discharges from the dock area. Repair pumps and restore sump/pit
collection system to full operating mode as soon as possible. O&M of this sump/pit collection system should remain a top
priority, especially for the NUCOR maintenance and environmental staff. In addition, vac/sweeping occurs at the dock
loading area on a weekly basis. Given the continuous & intense industrial activities at the dock area, it is suggested that
closer monitoring and possibly more frequent vac/sweeping be considered.
6. Port Road: This is an existing haul road used by heavy equipment to transport scrap metal from the dock to the main
plant. There are large grass collection swales adjacent to, and along both sides of Port Road. The existing steep slopes &
grades only allow a portion of runoff from Port Rd to enter the grass swales for treatment prior to discharging to the Chowan
River. Based on the intense heavy equipment traffic of Port Rd and the proximity to the Chowan River, the stormwater runoff
from this drainage basin could pose significant problems if not treated adequately. The environmental staff of NUCOR is
proposing to establish (2)additional outfalls [D1 and D2] at these collection swales to more closely monitor this drainage
basin. The grading along Port Rd, the collection swales, the existing rock check dams, the rip-rap outlets at the Chowan
River's edge need to be evaluated for any necessary repairs.
Due to problems maintaining pH within the required 6-9 range in the past, NUCOR installed and maintains a continuous pH
monitor and CO2 feed system at the outlets of Ponds B1 and Al. In reviewing NUCOR's reported sampling data, the pH
values in the discharge from these (2) ponds is typically at, or above 8.5. Currently, the pH system is calibrated on a
monthly basis, with some variations noted between the surface water within the ponds and the resulting discharge. It was
suggested that NUCOR staff might re-evaluate the pH monitor/feed system and consider making adjustments to bring the
pH values closer to the neutral range, rather than remain consistently at the upper range. We will be interested in your
further evaluation and comments regarding this pH system.
Paper DMRs have been received from Nucor, but it is also recommended that eDMRs may be submitted to DEQ-DEMLR.
Here's the link with details how to complete the eDMR registration process:

Good morning,
After reviewing everything provided so far, I have a few follow up questions. See below.
• The information provided does not describe activities taking place in drainage areas D1 or D2 nor other
unidentified basins (C, D, E, F, G, H). Activities taking place in the D1 drainage area include scrap handling,
vehicle traffic, and vehicle maintenance. Activities in the D2 drainage area include only scrap handling and
vehicle traffic. As for basins C, E, F, G, H—these areas are all undeveloped, heavily wooded areas with no
activity taking place in them. I went back to the drawings we submitted with our application and could not find
basin D. There is D1 and D2 which I just mentioned, but no D. Let me know if this is something I've overlooked.
• Information in the permit file history indicates there was a drainage area B5,which contained the dock facility,
where steel contained in barges is unloaded by cranes and transported by trucks, and access roads. Is this
drainage area still active? If so,which outfall does it drain to? Yes, drainage area B5 is still active. After going
through an oil/water separator,the water gets pumped via underground piping to our 131 pond,then flows out
the 131 outfall.
• Please confirm the below are the appropriate industrial activities for each outfall: All is correct except for Outfall
SW003. I've added drainage area B5 to that outfall list.
Outfall SW001: Outfall Al; Drainage Areas Al,A2, and A4
Drainage area consists of the steel slag processing plant, cooling towers, an electrical substation, alloy and flux handling
operations, equipment/bone yard,finished product, wood, sandblast material, process water,water treatment
chemicals, water treatment sludge, petroleum filling, and stormwater ponds Al and A2.
Outfall SW002: Outfall A3; Drainage Area A3
Drainage area consists of scrap handling/processing, an electrical substation, alloy and flux handling, steel scrap storage
area, railroad tracks, creosote railroad ties, and stormwater pond A3.
Outfall SW003: Outfall 131; Drainage Areas B1, B2A, B3, B4, and B5
Drainage area consists of the steel mill main plant areas, roads, parking lots, dumpsters, buildings, cooling towers, an
electrical secondary substation, natural gas valve station, warehouse receiving/unloading, slab handling, oxygen
manufacturing facility, electrode storage, baghouse and dust unloading, spray chamber material, injection carbon
handling/storage, emergency fire loop pond, refractory operation, outdoor storage of steel scrap and finished product,
port equipment maintenance/transport facilities, and stormwater ponds BI and B2.
Outfall SW004: Outfall Cl; Drainage Areas 13213 and C1
Drainage area consists of railway tracks, creosote railroad ties,vehicle maintenance, plate steel Iaydown yard,truck
staging area, scrap scales, and stormwater pond Cl.
Outfall SW005: Outfall D1; Drainage Area D1
Drainage area consists of the port terminal building and an access road.
Outfall SW006: Outfall D2; Drainage Area D2
Drainage area consists of an access road.
Thank you,

Good afternoon, Brianna,
Please see our response to your questions in red below. I was also able to update the various contact information
forms. Unfortunately, our V.P./General Manager who will act as the Signature Authority will be out of town for a couple
of weeks. We had him sign a "Delegation of Signature Authority" back in February, shortly after he became our new V.P.
& General Manager, but the form is not quite the same as the one you provided in the link. Please see his signature
attached to this email and let me know if it will suffice.
Let me know if there is anything else you need from me.
Thank you,

Good afternoon,
After revieing the information provided, I have some follow up questions.
• The coordinates for 4 outfalls were provided, however,the permit renewal application states there are 6
outfalls. Please provide the outfall coordinates of the drainage basins D1 and D2 and a description of industrial
activity that occurs within each basin. D1 = 36.3606, -76.8072, D2 =36.3604, -76.8069
6

• Please provide more information on what contractor activities take place in drainage basin Cl. The contractor
activities that occur in the drainage basin Cl is mainly administrative, storage, and product staging. This area is
where all our contractors have their office buildings or trailers, and any sort of shop/garage where they may do
maintenance on mobile vehicles. This area also contains a large laydown yard where our plate steel is
organized and staged for pickup and delivery.
• There are additional basins in the maps provided with the application. Where does stormwater in each of these
basins discharge to? Drainage areas Al,A2, and A4 all drain to outfall Al. Drainage area A3 drains to outfall
A3. Drainage areas 131, 132A, B3, and B4 all drain to outfall B1. Drainage area 13213 drains to outfall Cl. Drainage
area D1 drains to outfall D1 and drainage area D2 drains to outfall D2.
• Are antimony and magnesium used, stored, or processed anywhere onsite? We do not use, store, or process
antimony or magnesium on site.

Good morning, Brianna,
Please see our response to the questions you requested. Our monitoring data for 2021 and 2022 are attached to this
email.
As Bill had mentioned,we have had some leadership changes over the past three years. When I tried to click on any of
the request forms to update our information, I keep getting a "Service Unavailable" and "HTTP Error 503" message. Is
there another way I can update this information?
Description of industrial activity occurring onsite
Nucor Steel located in Cofield, North Carolina is a steel recycling facility that utilizes a 250 ton direct current (DC) electric
arc furnace (EAF) to produce molten steel from steel scrap. The molten steel is refined to produce customer specified
grades of steel and then cast via a water cooled continuous slab caster. These slabs are then reheated in a natural gas
direct fired reheat furnace and rolled into finished steel plates of various dimentions. The EAF exhausts through a direct
shell evacuation system and through a melt shop roof canopy that vents exhaust into a fabric filter baghouse. One ladle
metallurgical furnace (LMF) also vents into the same fabric filter baghouse. The baghouse is a negative pressure design
whereby emissions exhaust to the atmosphere via a single stack.
Confimation on the number of outfalls and associated coordinates
Currently there are four outfalls. There ID numbers and associated coordinates according to Google Maps are as follows:
Pond Al: 36.35361,-76.80083
Pond A3: 36.35306,-76.80083
Pond 61: 36.35778, -76.80667
Pond Cl: 36.34111, -76.82083
Description of industrail activity in each drainage basin
8

Al Basin: Slag Handling/Processing
A3 Basin: Scrap Handling/Processing
B1 Basin: Steel Mill and Parking Lots
C1 Basin: Railway traffic and Contractor activities
SIC(NAICS) code: 331110
Monitoring data since permit application was submitted (Jan. 2021): See attachments
Verification that information in renewal application is still complete and correct: All is still true and correct
Explanation of any operational changes since renewal application was submitted: Nucor's Blast and Paint line went
operational in December 2021. Although this was an addition to our operational capacity,this change did not affect any
stormwater ditches, basins, or ponds.
Please let me know if you have any questions.

This message came from outside of Nucor.
Good morning,
The Division of Energy, Mineral, and Land Resources (DEMLR) Stormwater Permitting Program
acknowledges receipt of your renewal application for coverage under NPDES Permit Number NCS000379.
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
10

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 Nucor Steel Hertford County facility
(NCS000379). 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 onsite;
• Confirmation on the number of outfalls and associated coordinates;
• 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 Geor og ulias
• 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.

Good afternoon, Brianna,
Please see our response to your questions in red below. I was also able to update the various contact information
forms. Unfortunately, our V.P./General Manager who will act as the Signature Authority will be out of town for a couple
of weeks. We had him sign a "Delegation of Signature Authority" back in February, shortly after he became our new V.P.
& General Manager, but the form is not quite the same as the one you provided in the link. Please see his signature
attached to this email and let me know if it will suffice.
Let me know if there is anything else you need from me.
Thank you,
Mike

Good afternoon,
After revieing the information provided, I have some follow up questions.
• The coordinates for 4 outfalls were provided, however,the permit renewal application states there are 6
outfalls. Please provide the outfall coordinates of the drainage basins D1 and D2 and a description of industrial
activity that occurs within each basin. D1 = 36.3606, -76.8072, D2 =36.3604, -76.8069
• Please provide more information on what contractor activities take place in drainage basin Cl. The contractor
activities that occur in the drainage basin Cl is mainly administrative, storage, and product staging. This area is
where all our contractors have their office buildings or trailers, and any sort of shop/garage where they may do
maintenance on mobile vehicles. This area also contains a large laydown yard where our plate steel is
organized and staged for pickup and delivery.
• There are additional basins in the maps provided with the application. Where does stormwater in each of these
basins discharge to? Drainage areas Al,A2, and A4 all drain to outfall Al. Drainage area A3 drains to outfall
A3. Drainage areas B1, B2A, B3, and B4 all drain to outfall B1. Drainage area B2B drains to outfall Cl. Drainage
area D1 drains to outfall D1 and drainage area D2 drains to outfall D2.
• Are antimony and magnesium used, stored, or processed anywhere onsite? We do not use, store, or process
antimony or magnesium on site.

Good morning, Brianna,
Please see our response to the questions you requested. Our monitoring data for 2021 and 2022 are attached to this
email.
As Bill had mentioned,we have had some leadership changes over the past three years. When I tried to click on any of
the request forms to update our information, I keep getting a "Service Unavailable" and "HTTP Error 503" message. Is
there another way I can update this information?
Description of industrial activity occurring onsite
Nucor Steel located in Cofield, North Carolina is a steel recycling facility that utilizes a 250 ton direct current (DC) electric
arc furnace (EAF) to produce molten steel from steel scrap. The molten steel is refined to produce customer specified
grades of steel and then cast via a water cooled continuous slab caster. These slabs are then reheated in a natural gas
direct fired reheat furnace and rolled into finished steel plates of various dimentions. The EAF exhausts through a direct
6

shell evacuation system and through a melt shop roof canopy that vents exhaust into a fabric filter baghouse. One ladle
metallurgical furnace (LMF) also vents into the same fabric filter baghouse. The baghouse is a negative pressure design
whereby emissions exhaust to the atmosphere via a single stack.
Confimation on the number of outfalls and associated coordinates
Currently there are four outfalls. There ID numbers and associated coordinates according to Google Maps are as follows:
Pond Al: 36.35361,-76.80083
Pond AI 36.35306,-76.80083
Pond B1: 36.35778, -76.80667
Pond Cl: 36.34111, -76.82083
Description of industrail activity in each drainage basin
Al Basin: Slag Handling/Processing
A3 Basin: Scrap Handling/Processing
B1 Basin: Steel Mill and Parking Lots
C1 Basin: Railway traffic and Contractor activities
SIC(NAICS) code: 331110
Monitoring data since permit application was submitted (Jan. 2021): See attachments
Verification that information in renewal application is still complete and correct: All is still true and correct
Explanation of any operational changes since renewal application was submitted: Nucor's Blast and Paint line went
operational in December 2021. Although this was an addition to our operational capacity,this change did not affect any
stormwater ditches, basins, or ponds.
Please let me know if you have any questions.

Good morning, Brianna,
Please see our response to the questions you requested. Our monitoring data for 2021 and 2022 are attached to this
email.
As Bill had mentioned,we have had some leadership changes over the past three years. When I tried to click on any of
the request forms to update our information, I keep getting a "Service Unavailable" and "HTTP Error 503" message. Is
there another way I can update this information?
Description of industrial activity occurring onsite
Nucor Steel located in Cofield, North Carolina is a steel recycling facility that utilizes a 250 ton direct current (DC) electric
arc furnace (EAF) to produce molten steel from steel scrap. The molten steel is refined to produce customer specified
grades of steel and then cast via a water cooled continuous slab caster. These slabs are then reheated in a natural gas
direct fired reheat furnace and rolled into finished steel plates of various dimentions. The EAF exhausts through a direct
shell evacuation system and through a melt shop roof canopy that vents exhaust into a fabric filter baghouse. One ladle
metallurgical furnace (LMF) also vents into the same fabric filter baghouse. The baghouse is a negative pressure design
whereby emissions exhaust to the atmosphere via a single stack.
Confimation on the number of outfalls and associated coordinates
Currently there are four outfalls. There ID numbers and associated coordinates according to Google Maps are as follows:
Pond Al: 36.35361,-76.80083
Pond A3: 36.35306,-76.80083
Pond B1: 36.35778, -76.80667
Pond Cl: 36.34111, -76.82083
Description of industrail activity in each drainage basin
Al Basin: Slag Handling/Processing
A3 Basin: Scrap Handling/Processing
131 Basin: Steel Mill and Parking Lots
C1 Basin: Railway traffic and Contractor activities
SIC (NAICS) code: 331110
1

Monitoring data since permit application was submitted (Jan. 2021): See attachments
Verification that information in renewal application is still complete and correct: All is still true and correct
Explanation of any operational changes since renewal application was submitted: Nucor's Blast and Paint line went
operational in December 2021. Although this was an addition to our operational capacity,this change did not affect any
stormwater ditches, basins, or ponds.
Please let me know if you have any questions.
Thank you,

This message came from outside of Nucor.
Good morning,
The Division of Energy, Mineral, and Land Resources (DEMLR) Stormwater Permitting Program
acknowledges receipt of your renewal application for coverage under NPDES Permit Number NCS000379.
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 Nucor Steel Hertford County facility
(NCS000379). 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 onsite;

• Confirmation on the number of outfalls and associated coordinates;
• 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

Nucor Steel— Hertford
Renewal Application Form
Facility/Activity Changes
There are two categories of facility/activity changes at the Nucor Steel—Hertford facility that we would
like to address in the NPDES permit renewal process. First,we have discovered two new stormwater
drainage areas along Port Road that discharge at the Dock Port on the Chowan River.Second,through
performance of our visual observations we have noticed the potential for several non-stormwater
discharges at the site that we would like to be considered allowable, non-stormwater discharges. Each
of these proposed changes are discussed below in more detail.
1. New Stormwater Discharges
Nucor Steel—Hertford discovered two new stormwater drainage areas along Port Road at the north end
of the facility.There are drainage ditches on both sides of Port Road that collect and channel
stormwater runoff from industrial activities to two point-source discharges at the Dock Port on the
Chowan River.The discharge areas are similar in nature and effluent quality is expected to be similar.
We would like to have these two outfalls added to the renewed permit.We understand that once these
outfalls are permitted,we can prepare and submit a Representative Outfall Status(ROS) Request Form
(Form No.SWU-ROS-2009)which will allow Nucor Steel—Hertford to analytically monitor one of these
two representative outfalls. Furthermore, if ROS is granted for these two outfalls,we understand both
outfalls will still be subject to qualitative monitoring requirements outlined in the permit.
2. Non-Stormwater Discharges
We understand several of these non-stormwater discharges(i.e.,fire-fighting activities,fire hydrant
flushings, potable water, potable water line flushings,air conditioning condensate,foundation drains,
and water from footing drains) described below are already considered allowable non-stormwater
discharges per the definition of allowable non-stormwater discharges in Part IV of the current permit,
however,we listed them here for completeness.
a. Fire-Fighting Activities-Discharges from emergency fire-fighting activities and uncontaminated
fire hydrant flushings (excluding discharges of hyperchlorinated water unless the water is first
dechlorinated and discharges are not expected to adversely affect aquatic life). Nucor flushes
fire hydrant lines once annually.Water from fire hydrants comes directly from groundwater
wells.This discharge may be present in all drainage basins, but most prevalent in Al and Bl
drainage areas.
b. Potable Water-Potable water sources(excluding discharges of hyperchlorinated water unless
the water is first dechlorinated and discharges are not expected to adversely affect aquatic life).
Occasionally Nucor must flush potable water lines to ensure proper sampling and maintenance.
This discharge may be present in drainage basins including Al,A3, 131,C1,and D1.
c. Pressure Washing Buildings-Water from the routine external washing of buildings,conducted
without the use of detergents and other chemicals.This discharge may be present in drainage
basins including Al,A3, B1,C1,and D1.
EHS Support LLC 1

d. Air Conditioning Condensate-Uncontaminated air conditioner condensate,compressor
condensate,steam condensate, and condensate from the outside storage of refrigerated gases
or liquids.This discharge may be present in drainage basins including Al,A3, B1,Cl,and D1.
e. Water in Basement Sumps-Water from foundation or footing drains where flows are not
contaminated with pollutants(e.g., process materials,solvents,and other pollutants). Nucor has
a procedure outlined in its SWPPP including the mandatory inspection of stormwater in
basements before sumps are allowed to discharge.This discharge may be present in drainage
basins B1 and Al.
f. Dust Suppression-Uncontaminated water used for dust suppression. Nucor is required under
its Title V air permit to conduct dust suppression of its roadways.Water for dust suppression on
roadways is taken from the Al stormwater pond and the Fire Loop system which is supplied by
groundwater.This discharge may be present in drainage basins including Al,A3, B1, Cl, D1,and
D2.
g. Cooling Tower Mist-Nucor Steel operates large,contact and noncontact cooling water towers
in the Outfall Al drainage basin, and two smaller cooling towers in the B1 drainage basin.The
water used in the towers is treated with various chemicals to improve and sustain cooling tower
performance.Table 1 is a list of the chemicals used in the water systems. Each cooling tower is
equipped with drift eliminators to minimize cooling tower mist deposition in the stormwater
drainage areas.The drift eliminators are thoroughly inspected on an annual basis, and
preventive maintenance is conducted in accordance with established schedules. Repairs, if
needed, are conducted in a timely manner. Nucor Steel has observed the deposition of cooling
tower mist in the areas outside the cooling tower basins.A portion of the mist evaporates and
the balance is absorbed by the soil or pavement during dry conditions. During precipitation
events the mist will commingle with the stormwater runoff and discharge to Outfall Al and
Outfall B1. Based on analytical data collected over the current permit cycle(August 2016 to
October 2020),the cooling tower mist does not appear to negatively impact the water quality at
Outfall Al and Outfall B1.
Based on this information,we respectfully request the above listed non-stormwater discharges to
be considered allowable, non-stormwater discharges in the renewed permit.

EXCERPTS OF BEST MANAGEMENT PRACTICES FROM NUCOR STEEL HERTFORD'S
STORMWATER POLLUTION PREVENTION PLAN, REVISION 5, December 23, 2019
6.4 Best Management Practices
BMPs are measures used to prevent or mitigate pollution from any type of activity. BMPs have
a very broad definition and may include materials management practices, housekeeping,
preventative maintenance, inspections,spill prevention/response,sediment and erosion control,
and management of runoff. Other BMPs include,but are not limited to debris control,vegetative
ground cover, infiltration, stormwater detention or retention where necessary and sediment
catch basins. The need for BMPs will be based on the assessment of the potential of sources
contributing significant quantities of pollutants to stormwater discharges and data collected
through monitoring and auditing.
6.4.1 Scrap Processing BMPs
NSHC produces high quality steel and imposes strict limitations on the quality of scrap metal it
purchases. To this end, NSHC places restrictions on all scrap steel purchased and used in its
manufacturing operations. NSHC's scrap specification minimizes the potential for contaminants
being present in the scrap, and thus, minimizes the potential for releases to the environment. All
scrap materials must be depleted to the extent practicable of free organic liquids such as oils,
greases, hydraulic fluids and other liquid contaminants. Lead and mercury-containing
components, such as batteries, battery cables, wheel weights from vehicle rims and mercury
switches are also removed from scrap to the extent practicable. All scrap loads are visually
inspected prior to unloading and NSHC rejects any load with visible free liquids or other apparent
contamination. Routine inspections of the scrap yard are also conducted to monitor for visible
signs of oil and grease or other contamination. Awareness training provided to the scrap yard
team members emphasizes immediate cleanup of any identified pollutant release, either from
the scrap itself or the scrap handling equipment. Last, the stockpiles are not covered but are
underlain by slag that is porous and generally impedes solids transport. Erosion from hauling
activities is minimized by the placement of slag on exposed ground surfaces. See Appendix D of
SPPP for more information on NSHC's Scrap Management Plan.
6.4.2 Slag Processing BMPs
Analytical test results support the fact that the metals in the slag are generally not leachable as
determined by TCLP, SPLP, and ASTM Methods. Further studies on the beneficial reuse of slag
have also been conducted by the Steel Manufacturers Association and support this conclusion.
The resultant lime content of slag could contribute to an elevated pH in stormwater; as a result,
the facility conducts semi-annual pH monitoring in required by the current NPDES Permit.
Because slag is heavy, it is unlikely that the material itself would be washed away with
stormwater flow from an area with such flat topography. Routine inspections of the slag
processing area are conducted,and general awareness training is provided to the slag processing
contractors that emphasizes immediate clean-up of any identified release from slag processing
equipment.

6.4.3 Bone Yard BMPs
All liquids contained in equipment, including hydraulic line fluid,coolant and any other liquid that
could become a pollutant source, are drained prior to placing the equipment in bone yard areas,
thus minimizing potential pollutant sources. Generally these area are surrounded by good
vegetative buffers allowing any sediment in the stormwater to settle out before reaching the
outfall.
6.4.4 Fueling Stations:
Fueling stations are located around the NSHC site and can be located on the maps within the
SPCC Plan in Appendix B of the SPPP. All fuel tanks are double-walled with an automatic shut-
off device shall be installed on all gasoline and diesel fuel pumps. General BMPs for fueling
stations include:
• Spills and overfill prevention equipment shall be installed on tanks and pumps
• Team members shall avoid "topping off"vehicle fuel tanks
• Located on paved concrete pads where possible
• Grading, berming or curbing fueling areas to avoid stormwater runoff.
• Spill kits with absorbent materials are placed near each fueling station around the site.
Spill kits are inspected quarterly by the environmental department to ensure supplies are
fully stocked.
6.4.5 Baghouse Maintenance and Dust Handling BMPs
During loading of baghouse dust to rail car the rail car loader shall sweep up any spilled dust in
the silo area. The swept up dust shall be placed in the satellite drums located at the silo. Labels
and covers shall be kept on the satellite drums at all times. When performing work on the screw
conveyors, the dust shall be run out of the conveyors and conveyed to the silo. Any remaining
dust shall be vacuumed or swept and placed in the labeled satellite drums. During cleaning or
scraping of the fan wheels the scraped dust and materials shall be kept inside the fans to be
conveyed to the baghouse, with exception of the main air fans. Used filter bags will be placed in
a sealed plastic bag for disposal. When performing maintenance in a baghouse compartment,
any dust found on the floor is swept down a filter bag hole in a cell plate(after removal of a filter
of course).
6.4.6 Dock Area BMPs
No discharge of liquid material from either barges or tug is allowed at or around the dock facility
at NSHC. Proper removal of this material is the responsibility of the transport company. No
maintenance of barges or tug is to be performed, unless in an emergency, at the dock facility at
NSHC. Maintenance of barges and tug is the responsibility of the transport company and should
be scheduled at deep-water ports.Any observed leak or spill shall be immediately contained and
cleaned up. The cause of the problem should be repaired as soon as possible. Drip pans or similar

containers shall be placed under any leaking piece of stationary equipment until the leak is
repaired. Dry cleanup methods, using absorbent material shall be utilized where appropriate on
all significant leaks and spills. An adequate supply of absorbent materials shall be maintained
and used absorbent material shall be swept up and properly disposed.
Oily equipment and vehicles are not to be washed or steam cleaned on the dock area. Loading
areas should be swept on a regular basis, and equipment shall be inspected regularly for leaks.
5.4.7 Loading/Unloading BMPs
All loading and unloading of tank vehicles takes place only in the designated, secure
loading/unloading areas. Loading and unloading areas are graded, bermed or within a curb area
around loading area to prevent stormwater runoff contamination. Trucks shall be inspected
regularly for leaks and any accidental spills will be cleaned up immediately.
6.4.8 Container Protection BMPs
Warning signs are posted at appropriate locations throughout the facility to prevent vehicles
from damaging aboveground piping and appurtenances. Most of the aboveground piping is
located within areas that are not accessible to vehicular traffic (e.g., inside diked area).
Additionally, concrete blocks and other guards are placed where needed to protect equipment
from vehicular collisions.
6.4.9 Sediment and Erosion Prevention BMPs
The topography at the Nucor facility is primarily flat with dense vegetation typical of the North
Carolina coastal region. Unpaved yard/operation areas are periodically re-graded to prevent the
formation of ruts and gullies. Gravel and stone aggregate placement at the sites are coarse,with
a minimum amount of fine particles, which would be easily flushed by runoff.A good vegetative
cover shall be maintained in non-operational unpaved areas. Vegetation around the 4
stormwater ponds and ditches leading to the ponds is encouraged as long as flow is not impeded.
Any observed erosion, scouring or sedimentation shall be controlled using appropriate
vegetative, stabilization, or structural measures. Vegetative filter strips may be installed to
provide a buffer area around the facility operation areas.Grassed swales may be used to stabilize
eroded ditches or channels.
Management of runoff involves stormwater treatment measures. Source reduction and
containment/diversion BMPs are preferred to stormwater treatment. Even though most of the
stormwater issues at Nucor are well suited to source reduction and containment/diversion BMPs,
stormwater treatment is provided as an additional source of control to ensure protection of
water quality.
Nucor's stormwater system exceeds all State requirements. The stormwater system utilizes
grassed swales and 4 wet detention ponds. The dense growth of vegetation is used to absorb
pollutants and filter sediment. Pond surface areas exceed requirements by 41-110% and have
the capacity to detain runoff from a 100-year storm event. In addition, forebays are used and in
many cases are larger than required.

6.4.10 pH Control
Due to high pH levels from the 61 and Al ponds,a pH control system has been installed to ensure
levels are within the benchmark of 6 to 9. A permanent system which includes an addition of
carbon dioxide just before the B1 and Al outfall is able to monitor the current pH level, and add
carbon dioxide as necessary.

PLANNED BEST MANAGEMENT PRACTICES
Nucor Steel Hertford plans on having their slag processing contractor, Harsco Environmental,
install a wash pad for large off-road trucks and equipment by the end of calendar year 2021. The
wash pad will use potable water and eco-friendly detergents and will be equipped with an
oil/water separator. The oil/water separator will discharge to the sanitary sewer system to the
Town of Winton's publicly owned treatment works(POTW). Preliminary estimates of wastewater
discharge volume are 6,000 gallons per week (based on 20 hours per week at 5 gallons per
minute).
