Reference. NPDES Storm Water Permit #: NCS000379
Dear Mr. Bennett,
Nucor Steel Hertford County was issued a new NPDES permit on August 1, 2016 and would like
to start following the new permit monitoring schedule_ This letter is notification of that and what
we have done to meet the permit requirements.
We have been conducting monthly sampling of our storm water for the past five years due to
intermittent exceedances of pH in two of our ponds. In response to this we followed the tier
response program listed in our permit to determine the best route to take in order to mitigate this
issue.
We chose to try two different treatment systems to determine the better option, an acid feed system
and a CO2 feed system. The acid feed system feeds acid into the water as it flows through the
outfall. With a large rainfall creating a large amount of flow, the acid feed system cannot keep up
and thus the water does not get treated with the acid. This system also requires the transport of
acid across our plant site. The CO2 treatment system injects CO2 into the water as it flows through
the outfall. Since installation of this system, we have had no issue with pH. We are in the process
of installing the same CO2 treatment system at the other outfall.
We have submitted a Discharge Monitoring Report for September 2016 and we will consider our
October 2016 sampling event the first sampling event under the new permit monitoring schedule
and will continue to follow this schedule unless we are required to start following Tier Two or
Three monitoring.
If you should have any questions, please contact me at [phone].
Sincerely,
RECEIVED

Permit No. NCS000379
(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• ow�WheTever 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 documentrthe feasibility of diverting the stormwater
run-on away from areas of potential contamination.
Secondary Containment Re uiremeiits a)fd Records. Secondary containment is
required for: bulk storage.of liquidmaterials: storage in any amount of Section 313
of Title III of the SuperndAm`end fuments and Reauthorization Act (SARA) water
priority chemicals: and starage,,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 andatored materials and their associated secondary containment11
areas shall be maintained.Af"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
Part 11 Page 2 of 15

Permit No. NCS000379
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 runoffgrdugh spills or exposure of
materials associated with the facility operations.^The SPRP must be site stormwater
specific. Therefore, an oil Spill Prevention Control an&Countermeasure plan (SPCC)
may be a component of the SPRP, but may not be-suffficient_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,s--
4. Preventative Maintenance and Good,Housekeeping Program. A preventative
maintenance and good housekeeping progra�m,shall be developed and implemented.
The program shall address all.stormwate'r 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,h/ousekeeping 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 SPPP. 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 SPPP.
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, C, and D 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
Part 11 Page 3 of 15

Permit No. NCS000379
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 SPPP shall identify a specific position or positions responsible
for the overall coordination, development, implementation, and revision of the SPPP.
Responsibilities for all components of the SPPP shall be documented and position
assignments provided.
B. SPPP Amendment and Annual Update. The permittee shall amend the SPPP
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 SPPP shall be reviewed and updated on an annu♦al,basis. The annual update
shall include:
(a) an updated list ofsignificantspills orfleaZ-1�nZ
s for the previous three
(3) years, or the notation that no spills,\occurred (element of the Site
Overview);
(b) a written re -certification that the'siormwater outfalls have been evaluated for
ri rr♦ /
the presence of non-stormwat r discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on -site stormwater
BMPs (BMP Summary eleme t(-ofthe Stormwater Management Strategy).
(d) a review and comparison ofsample analytical data to benchmark values (if
applicable) over the-past.yearincluding 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 w,eb�site.(See'Monitoring Farms' here:
mineral-land-permits/stormwater-permits/npdes-industrial-sw).
The Director may notify the permittee when the SPPP 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 SPPP to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part II1, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
9. SPPP Implementation. The permittee shall implement the Stormwater Pollution
Prevention Plan and all appropriate BMPs consistent with the provisions of this permit,
in order to control contaminants entering surface waters via stormwater.
Implementation of the SPPP 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 (S) years and made
available to the Director or the Director's authorized representative immediately upon
request.

Permit No. NCS000379
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 measureable 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
peermittee obtains approval from the local DEMLR Regional Engineer. See Definitions.

sampling) during a measureable 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.
Part II Page 9 of 15

Permit No. NCS000379
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.
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.
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"

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.
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.
Part 11 Page 6 of 15

Permit No. NCS000379
The permittee shall compare monitoring results to the benchmark values in Table 3.
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 3 are not permit limits but should be used as guidelines for
implementation of the permittee's SPPP. 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.
Part H Page 7 of 15

Permit No. NCS000379
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 SPPP. include the date and value of the benchmark
exceedence, 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 parame.ter s Laratel trigger a tiered response.
Tier Two
If: The first valid sampling results from two consecutive mo' n toring periods (omitting periods with no
discharge) are above the benchmark values, or outside o thee etchmark range, for any specific parameter at
a specific discharge outfall;
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tie • One.
2. Immediately institute monthlyAmonitonng 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 (a�nals�ytical nd•qualitative) monitoring shall continue until three
consecutive sample results arelbe ow tfie b nchmark values or within benchmark range.
3. If no discharge occurs duringrhe sampling period, the permittee is required to submit a monthly
monitoring report indicating No Flo -' to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 andff, the permittee may, after two consecutive exceedances, exercise the
option of contacting the DEM 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 SPPP.
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; or
• 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.

Permit No. NCS000379
This site discharges to impaired waters experiencing problems with a fish advisory for
mercury. A Total Maximum Daily Load (TMDL) was approved for this segment of the
Chowan River and Brooks Creek You should continue to monitor for this pollutant of
concern in the future and submit results to the Division. The Division will consider the
monitoring results in determining whether additional BMPs are needed to control the
pollutant of concern to the maximum extent practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a
timetable for incorporation of those BMPs into the Stormwater Pollution Prevention Plan.
SECTION C: QUALITATIVE MONITORING REQUI
The purpose of qualitative monitoring is to evaluate the-effecfiveness of the Stormwater
Pollution Prevention Plan (SPPP) and identify new potential sources of stormwater
pollution. Qualitative monitoring of stormwater outfaIN,must be performed during a
measurable storm event. I-- "1
Qualitative monitoring requires a visual inspection bf dach stormwater outfall regardless of
representative outfall status. Qualitative �monito ng shall be performed semi-annually as
specified in Table 4, and during required analytical monitoring events (unless the permittee
is required to perform further qualitative monitoring per the Qualitative Monitoring
Response, below). Inability to inoni or Uecause of adverse weather conditions must be
documented in the SPPP andf6corded on the Qualitative Monitoring Report form (see
Adverse Weather in Definitions). 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

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'iinonitoring indicates that existing stormwater BMPs are
ineffective, or that significant stormwater contamination is present, the permittee shall

Qualitative Monitorin -Res onsi ..
Qualitative monitoring is for the purposes of evaluating SPPP 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.

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 be begun within
the first 30 minutes, and shall continue until completed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) that discharges
stormwater runoff from area(s) where vehicle maintenance activities occur, unless representative outfall
status (ROS) has been granted. A copy of the letter granting ROS shall be kept on site.
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 guage may
be substituted for an on -site reading.
Failure to monitor semi-annually per permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified time period, as provided in Part lI
Section B.
Monitoring results shall be compared to the benchmark values in Table 6. The benchmark
values in Table G are not permit limits but should be used as guidelines for the permittee's
Stormwater Pollution Prevention Plan (SPPP). Exceedances of benchmark values require
the permittee to increase monitoring, increase management actions, increase record
keeping, and/or install stormwater Best Management Practices (BMPs), as provided in Part
II Section B.

scientific practices shalPbe selecteeand used to ensure the accuracy and reliability of measurements
of the volume of monitored'dischaTEes.
4. Test Procedures
Test procedures for the analysis of pollutants shall conform to the EMC regulations published
pursuant to NCGS 143-215.63 et seq, the Water and Air Quality Reporting Acts, and to regulations
published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as
Amended, and Regulation 40 CFR 136.
To meet the intent of the monitoring required by this permit, all test procedures must produce
minimum detection and reporting levels and all data generated must be reported down to the
minimum detection or lower reporting level of the procedure. If no approved methods are
determined capable of achieving minimum detection and reporting levels below permit discharge
requirements, then the most sensitive (method with the lowest possible detection and reporting
level) approved method must be used.
5. Representative Outfall
If a facility has multiple discharge locations with substantially identical stormwater discharges that
are required to be sampled, the permittee may petition the Director for representative outfall status.
If it is established that the stormwater discharges are substantially identical and the permittee is
granted representative outfall status, then sampling requirements may be performed at a reduced
number of outfalls.

As required by our NPDES Stormwater permit, Nucor is submitting this notification that our
Stormwater Pond Al has exceeded the benchmark value established for pH, for four sampling
events.
We have conducted site inspections to determine if there are any contributing factors. Upon
inspection there have been no instances found that would cause an increase in pH in our
stormwater. With natural pH high in this area we strive to ensure our housekeeping of outside
areas is exceptional to minimize impacting our stormwater.
We have installed an acid feed system and a CO2 feed system on two separate stormwater
outfalls to help control pH. These systems are currently being evaluated on their effectiveness
to determine which system will be added, if needed, to other outfalls.
We have already implemented the Tier One and Tier Two responses, required by the permit
and we have conducted monthly monitoring for all parameters at every outfall since April of
2012 and will continue to do this until agreed otherwise.
If you have any questions, please call me at 252-356-3707.
Very truly yours,

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000379
Nucor Steel
Hertford County
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please
review the draft carefully to ensure thorough understanding of the conditions and
requirements it contains.
The draft permit contains the following significant changes from the facility's current permit:
1. You are required to collect analytical and qualitative monitoring samples during
"measurable storm events" as defined in Part IL Section B. This term is different
from the "representative storm event" in earlier permits.
2. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part H,
Section A.
3. Changes have been made to six monitoring parameters, including a change to five
benchmarks. Stormwater benchmarks are not permit limits, but rather guidelines for
implementing the Stonnwater Pollution Prevention Plan (SPPP). A benchmark
exceedance is not a permit violation; however, the permittee must respond to
exceedances as directed in the Tiers.
• The OR & Grease parameter is changed to Non -polar Oil & Grease [EPA
Method 1664 (SGT-HEM)]; the benchmark for Non -polar Oil & Grease is 15
mg/L.
• The benchmark for Copper is changed from 0.007 mg/L to 0.010 mg/L.
• The benchmark for Lead is changed from 0.003 mg/L to 0.075 mg/L.

• The benchmark for Silver is changed from 0.001 mg/L to 0.0003 mg/L.
• The benchmark for Zinc is changed from 0.067 mg/L to 0.126 mg/L
• Vehicle maintenance monitoring parameters have been revised as follows:
o Non -Polar Gil & Grease [EPA Method 1664 (SGT-HEM)] replaces
Oil & Grease/ T'PH. This requirement appears in all individual
stormwater permits; however, it only applies to facilities that
perform onsite vehicle maintenance activities. If the facility begins
vehicle maintenance during the permit cycle, the requirements shall
apply-
o pH monitoring is no longer required for discharges only associated
with vehicle maintenance activities.
4. A new section on Special Conditions has been added in Part II, Section E to comply
with federal regulations requiring electronic submittal of discharge monitoring
reports. This section of the permit will become effective December 21, 2016.
Please review the draft permit and submit any comments to me no later than 30 days
following your receipt of the draft. Comments may be emailed to me at
iulie.ventaloro(@cdenr.goy or mailed to my attention at NCDEQ, Land Quality Section,

Central Office Review Summary:
1. Special Issues:
o Added anew section on Special Conditions in Part II, Section E to comply with
federal regulations requiring electronic submittal of discharge monitoring
reports.
o Benchmark for silver has been lowered significantly. Benchmarks for lead,
copper and zinc have been increased. Make sure permittee made aware of these
changes.
2. Changes at the facility since previous permit:
o Added CO2 system to 131 pond and a sulfuric acid feed system to the Al pond to
address pH issues. CO2 is now their preferred method and they are looking at

how they could change to a CO2 system at the Al pond. This is complicated by
the rural location, lack of power, and configuration of the actual outfall.
o Added one new Normalizing Line and a DRI conveyor system with silos and day
bins. Also added additional railroad tracks and expansion of a couple buildings.
All of these had stormwater construction permits and the original ponds were
designed for 100% impervious surfaces.
o No changes to the locations of the ponds/outfalls.
3. Receiving Waters: Chowan River and Brooks Creek impaired for mercury; TMDL
approved 2012
4. Threatened and Endangered Species:
o Within 2 miles of the facility, the following aquatic species have been identified
by Natural Heritage Program database as threatened or endangered:
- Atlantic Sturgeon (Acipenser oxyrinchus) - federal endangered
- Eastern Pondmussel (Ligumia nasuta) - state threatened
- Tidewater Mucket (Leptodea ochracea) - state threatened
- Eastern Lampmussel (Lampsilis radiata) - state threatened
- Triangle Floater (Alasmidonta undulata) - state threatened
5. Analytical and jorguualitative monitoring during this past permit g;ycle: See data
provided in renewal application. Multiple exceedances of pH, copper, lead, zinc at
several outfalls. One exceedance of mercury. More recent data can be viewed in
Laserfiche at: hqp://Donal.ncdenr.org/uoup/lr/stormwater-dmrs {search by permit number).
G. Rationale for monitoring parameters:
o The Oil & Grease parameter for Vehicle Maintenance is changed to Non -Polar Oil
& Grease for consistency with other permits.
o Benchmarks for Copper, Lead, Silver, and Zinc were changed to reflect updated
science.
o pH monitoring is no longer required for discharges only associated with vehicle
maintenance activities.
7. Permit. Facility, and Owner Contacts updates:
® Confirmed contact information with permittee and updated BIMS if necessary.
® Obtained e-mail addresses for each contact and updated BIMS.
8. Annual Fees:
® Confirmed in BIMS that permittee does not owe fees.

Recommendations:
Based on the documents reviewed, the application information submitted on December 30,
2013 is sufficient to issue an Individual NPDES Stormwater Permit.
Central Office recommends reissuance of this permit with the same monitoring as the
previous cycle except for standard revisions to VMA monitoring for consistency with other
permits. The proposed draft permit reflects the most recent individual stormwater permit
template and boiler plate language, incorporating revisions that are similar to the
industrial general permits issued during 2012-13.

Also, while we were talking I mentioned that we were trying different pH controls on our ponds and to specify, we have
added a CO2 system to our B1 Pond and a sulfuric acid feed system to the Al Pond. The CO2 is now our preferred
method and we are looking at how we might be able to change to a CO2 system at the Al Pond. This is complicated by
the rual location, lack of power and the configuration of the actual outfall.
During our call, you also asked about any other changes at the facility and I mentioned some construction since the
appplication was submitted in 2013. Specifically, around the time that we submitted the application, we added one new
Normalizing Line and a DRI conveyor system with silos and day bins. Since then we have added additional railroad tracks
and an expansion of a couple of buildings. All of these have had stormwater construction permits associated with them
and the original ponds were designed for 100% unpermeable surfaces and the ponds and outfalls are all still in the same
locations.
If you have any questions, you know'how to reach me and if I am not availible, don't hesitate to contact Elizabeth at 252-

Re: Nucor Steel Hertford County
NPDES Storm Water Permit
Permit NCS000379
Dear Mr. Hodge,
RECEIVED
APR - 4 2012
DWQ-WARO
Nucor Steel Hertford County recently discovered that DWQ had issued a new NPDES
Storm Water Permit to our facility, effective August 1, 2009. Previously we had been
operating under a letter issued by the Washington Regional Office in 2006 granting an
extension of our prior permit, issued in 2001.
The reason for this oversight was that we did not realize that the permit had been
issued and did not receive a copy of it. Following our last on -site inspection in February
2010, we followed up on a punch list of items to work on from the inspection. These
items were completed during the spring of 2010. In September of that year we were
asked for an SMP and Annual Storm Water Report but mistakenly believed that this
information was being collected under the 2006 letter authorization since we had yet to
receive a copy of the new permit.
Since learning of the new permit about a week ago, we have reviewed it and would like
to report the following deviations from the permit and ask that you work with Nucor while
we correct them:
a. Missed monitoring for 3 Monitoring Periods — The new permit requires semi-annual
'monitoring while the prior permit required annual monitoring. Consequently, Nucor
sampled once each year from 2009-2011. Under the new permit we will be
sampling twice per year during the time period specified.
b. Since the new permit went into effect, we have missed the benchmark target for Cu
twice at Al Pond, once each for A3 and 131 Ponds. All other sampled parameters
were below the benchmarks or the detection limits used at the time of the sampling.
We are currently working on the Tier One and Tier Two responses required for
missing these benchmarks.

Re: NPDES Tier Three Response
Mr. Hodge,
RECEIVED
JUL - 6 2012
DWQ-WARO
As required by our NPDES Stormwater permit and as discussed during Bill Moore's recent visit,
Nucor is submitting this notification that our Stormwater Pond Al has exceeded the benchmark
value established for copper (Cu) of 7mg11, for four sampling events.
With our June sampling event, we will have our fourth pH at or in excess of 9 for ponds Al and
A3 and continue to see lower but close values in pond B1. We have already implemented the
Tier One and Tier Two responses, required by the permit and we have conducted monthly
monitoring for all parameters at every outfall since April of this year and will continue to do this
until agreed otherwise.
In addition, we have coordinated with the lab to have extra sampling equipment on -site for our
July sampling event, so that we can collect samples from the inlet of each pond. We intend to
use this additional information to better understand the potential sources of the Cu and high pH.
We have also scheduled a visit for next week, to a facility that uses CO2 to treat high pH in their
Stormwater outfalls. Once we learn more about this, we will be back in touch with you and Mr.
Moore, about the possibility of adding one of these systems here. Apparently while the CO2
system is more expensive than an acid feed system, there is less chance of missing on the low
end of the pH scale.
Very truly yours,
Terry Hairston

Site Plan
The site plan shall provide a description of the physical facility and the potential of pollutant sources that may
contaminate storm water runoff and discharges. The site plan contains the following information:
1. General Location Map
2. Narrative Description
3. Site Map
4. List of Significant Spills/Leaks of Potential Pollutants
5. Certification
General Location Map
Two general location maps are included. The first map is a USGS quadrangle map and the second is a drafted equivalent
map of the site and surrounding area. The maps illustrate the facility's location in relation to transportation routes and
surface waters of the state, and the name of the receiving water(s) to which storm water discharged through the outfalls
on site are located.
Nucor Steel is located in Hertford County, North Carolina. This site discharges storm water from four outfalls, which
feed into the Chowan River via wetland routes. Each outfall and its location have been listed in the outfail section of this
document.
This facility acquires scrap steel, melts, casts, and produces a final steel plate that meets the needs of the customer.
Narrative Description
A narrative description of practices that include storage, loading and unloading, outdoor processes, dust/particulate
control, and disposal of wastes is provided within the plan. Storm water is the discharge from any point source, which is
used for the collection, conveyance and is directly related to processing, manufacturing, or raw material storage on an
industrial site. The list of industrial activities can be found in 40 CFR 122.26 (b)(14). A BMP (Best Management Practice)
is required wherever storm water is associated with industrial activities at Nucor, to minimize the potential pollutant
loading to surface water. Storm water that is exposed to a material inventory that is deemed insignificant to the
operation of the facility is not required to have a BMP. Exposure of storm water to a significant material that does not
have a point sources discharge does not require the implementation of a BMP in order to minimize the potential of
pollutant loadings.

Basin Descriptions
Basin Al
The steel slag processing plant is located in this basin as well as storm water pond Al. Steel slag, steel skulls and mill
scale are stored on the ground in an open area adjacent to the processing plant. Steel scrap cutting operations also
occur in this basin. The steel slag, steel skulls and mill scale are directly related to manufacturing as is steel scrap cutting
operations. Therefore, precipitation in this basin is considered to be storm water associated with industrial activity.
Basin A2
Contains plant operational buildings, the main electrical substation, storm water pond A2, alloy and flux handling
operations, equipment/bone yard, finished product, wood, sandblast material, process water, water treatment
chemicals, water treatment sludge, and petroleum filling. If material is stored outside, then this area would be
associated with industrial activity; otherwise storm water from this area does not constitute storm water associated
with industrial activity.
Basin A3
Steel scrap storage area, including pig iron and painted scrap metal, railroad tracks, creosote railroad ties, and storm
water pond A3. The scrap is directly related to manufacturing and the precipitation is considered to be storm water
associated with industrial activity.
Basin B1
Buildings, roads, baghouse, injection carbon handling/storage, baghouse dust unloading operations, spray chamber
material, emergency fire loop pond, refractory operation, and storm water pond Bl are in this area. This basin does not
contain materials or conduct activities that are considered to be storm water associated with industrial activity.
Basin B2A
Contains the main plant areas, buildings, plant trash collection sites, helipad, natural gas valve station, parking lots,
warehouse receiving/unloading, slab handling, oxygen manufacturing facility, electrode storage, storm water pond B2,
and roads. Industrial activities and materials are exposed to storm water so this activity is considered to be storm water
associated with industrial activity.
Basin B2B
This area contains contractors work areas, railroad tracks, creosote railroad ties, storm water pond Cl, the
incoming/outgoing truck staging area and scales for incoming scrap. The scrap steel contained in railcars and on trucks
is directly related to manufacturing and is considered to be storm water associated with industrial activity.
Basin B3
Steel scrap and finished product may be stored outside the facility in this area. Port equipment maintenance/transport
facilities are located in this basin. These areas are directly related to manufacturing and are considered to be storm
water associated with industrial activity.
Basin Bd
Located north of the melt shop. This area contains buildings, roads, electrical secondary substation, and a storage area.
No material is exposed to storm water and the area is not considered to be storm water associated with industrial
activity.

Basin B5
The dock facility and access roads are located here. No active manufacturing or storage takes place in this area,
however, steel contained in barges is unloaded by cranes and transported by trucks and is directly related to
manufacturing. Therefore this area is considered to be storm water associated with industrial activity.
Basin C
Basin C contains a bypass to Bazemore Road and does not constitute storm water associated with industrial activity.
Basin D
This basin is comprised of a utility corridor with power lines, water lines, natural gas lines, and railroad tracks used for
transporting steel scrap and finished product. No active manufacturing or storage takes place in this area; however, the
scrap steel contained in rail cars is directly related to manufacturing and is considered to be storm water associated with
industrial activity.

List of Significant Spills or Leaks of Pollutants
During the previous three years, there have been no significant spills or leaks of pollutants and subsequently no
corrective actions taken to mitigate spill impacts.
Non -Storm Water Discharges
Nucor's Permit requires that separate NPDES permits be obtained for most non -storm water discharges. The permit lists
ten non -storm water discharges that are allowed without obtaining an NPDES permit. They include air conditioner
condensate without added chemicals, uncontaminated ground water, uncontaminated potable water, and discharges
resulting from firefighting.
The permit also requires that the facility be assessed for the presence of non- storm water discharge to the storm water
drainage system. Appendix B contains the non -storm water discharges observed during field assessment. The permit
also requires that a "responsible corporate official," such as the plant manager or vice president, certify by signature the
results of the field assessment.
There were no non -storm water discharges observed during the field assessment. Process water is contained in
separate ponds and is treated on -site. Water is no longer sent to the Town of Winton for treatment.
See attached certification in Appendix B.

Storm Water Management Plan
The purpose of the storm water management plan is to identify site -specific sources of storm water pollution based on
the field assessment and to develop best management practices to decrease and/or eliminate potential pollutant
sources. EPA guidance lists the preferred hierarchy of Best Management Practices (BMPs) which is:
1. Source Reduction: which includes preventative maintenance; spill prevention, chemical substitution,
housekeeping, and training.
2. Containment/Diversion: This includes segregating activities of concern, covering the activity, berming the
activity, and diverting the flow to grassed area.
3. Recycling
4. Storm Water Treatment
The storm water management plan should contain a narrative description of the material management practices
employed which control or minimize the exposure of significant materials to storm water, including structural and non-
structural measures. The storm water management plan, at a minimum, should include the following:

Study of Operation and Storage Practices
This section identifies storm water pollution sources observed during the facility's field assessment, as well as meetings
and discussions with Nucor personnel and consultants and discusses materials management practices for controlling or
minimizing exposure of significant material to storm water.
The basin description section of this plan describes various materials that are stored in the weather that are considered
storm water associated with an industrial activity. Therefore, a reasonable BMP for these activities is to continue to
ensure that the materials are clean when placed into storage and to inspect the storage area at least semiannually to
ensure material that may impact surface water is not being placed outside. The storm water management plan for the
facility includes 16 individual drainage basins. Ten of these basins are divided into four storm water management
systems that utilize wet detention ponds, three individual basins utilized grass swales and vegetative buffers for their
storm water management systems and three basins will not require storm water control measures as they will remain
unimproved.
Drainage basins Al, A2, and A4 form the first storm water system using wet detention pond Al and pond A2. Runoff
from these basins will be collected and transported via swales and culverts to ponds Al and A2. Pond A2 is used as a
forebay to wet detention pond Al in addition to the forebay areas within wet detention pond Al. The forebay areas
within pond Al are located where drainage flows directly from the drainage basins without passing through pond
A2. Pond A2 is connected to pond Al by culverts. Nucor has expanded the facility's alloy storage capacity; this
additional storage area will be an uncovered area approximately sixty feet by eighty feet, located east of the main
substation, which drains to the west. Nucor has constructed a cement pad with concrete walls surrounding the alloys to
minimize the potential amount of storm water contacting the alloy piles and constructed a storm water ditch west of the
alloy storage area to capture all runoff from the alloys.
Drainage basin A3 forms the second storm water system using wet detention pond A3. Runoff from this basin will be
collected and transported via swales and culverts to wet detention pond A3. A forebay is included in pond A3. Please
note the northern most drainage basin, A3, utilizes grass swales and vegetative buffers for its storm water management.
Drainage basins B1, 132A, B3, B4, and B5 form the third storm water system using wet detention pond Bl and pond .
B2. Runoff from these basins will be collected and transported via swales and culverts to ponds B1 and B2. Pond B2 is
used as a forebay to wet detention pond Bl in addition to the forebay areas within wet detention pond Bl. The forebay
areas within pond B1 are located where drainage flows directly from the drainage basins without passing through pond
B2. Pond B2 is connected to pond 131 by culverts. Runoff from basin 85 will be pumped to wet detention pond B1.
Drainage basin B26 forms the fourth storm water system using wet detention pond Cl. Runoff from these basins will be
collected and transported via swales and culverts to detention pond Cl. Forebays are included in pond Cl.
Wet detention ponds are used as the primary storm water treatment method for this mill. Wet detention ponds are
designed and configured to provide significant removal of pollutants from incoming storm water runoff. Design
parameters included were to provide sufficient surface area to allow 90% total suspended solids removal with designed
pool depths of 3-6 feet. Note wet detention ponds B1 and Al have a 7-foot permanent pool depth for storage of the 10
and 100-year storm events but were designed for TSS removal using the corresponding factors for a 6-foot permanent
pool. The wet detention ponds have an outlet orifice designed to remove the runoff from the 1" rain event from 2-5
days.

Loading and unloading operations for the mill occur both indoors/under cover and outside. Transfer operations taking
place under roof have adequate containment. Those operations taking place outdoors have secondary containment.
The used oil, hydraulic oil, and fuel tanks are either located indoors or in areas with secondary containment. There is a
potential for spills of these liquids if a tanker or connecting hose ruptures during a filling event. An attendant can
monitor all tank filling activities and be prepared to shut off all pumps and close all valves in the event of a tank or hose
rupture. Monitoring of the filling event constitutes a BMP for these sources.
Scrap metal is stored outside. Scrap is graded upon arrival and is returned if there is too much wood, fines, oil, or other
contaminants present or if radiation is detected. The scrap yard is segregated by type of scrap and all storm water
drains to ditches carrying flow to storm water Pond A3 for treatment. Based on the facility inspection, it appears that
these materials are being handled in a way that minimized exposure to storm water. The BMP options for these
potential sources of storm water contamination include preventative maintenance of transport equipment, good
housekeeping, and training. These BMPs include inspection of all scrap metal for contamination prior to outside storage
in the scrap yard.
Slag pots are loaded under a shelter to minimize exposure to storm water prior to being transferred to the slag
processing area (Basin Al). Steel slag and mill scale are stored on the ground in an open area adjacent to the processing
plant. Storm water runoff from this area flows to storm water Pond Al. The BMP options for these potential sources of
storm water contamination included preventative maintenance of transport equipment, good housekeeping, and
training.
The baghouse is located in Basin Bl. Nucor utilizes a screw conveyor at the bottom of the baghouse bin to a bucket
elevator storage silo that is an integral part of the baghouse. The screw conveyor is covered to minimized exposure to
storm water. The baghouse dust is transferred to railcars for transport via flexible hoses. The ground is paved and
swept as needed. There is a potential for spills of baghuse dust if a connecting hose ruptures or a rail car overflows
during a filling event. An attendant can monitor all rail car filling activities and be prepared to shut down the operations
in the event of a flex hose rupture or overfill. Monitoring of the filling equipment constitutes a BMP for these
sources. Based on the facility inspection, it appears that these materials are being handled in a way that minimizes
exposure to storm water. The BMP options for these potential sources of storm water contamination also included
preventative maintenance of equipment, good housekeeping, and training.

Environmental Management System: We Do It Right - It's Our Nature
Schedule for Secondary Containment
A schedule for secondary containment is required by Nucor's storm water permit. A schedule for secondary
containment is required for bulk storage of liquid materials, storage of any Section 313 water priority chemicals, or
storage of hazardous material to prevent leaks and spill from contaminating storm water runoff. If the secondary
containment devices are connected directly to storm water conveyance systems, the connection shall be controlled with
a manually activated valve or other similar devices (which shall be secured with a locking mechanism) and any storm
water that accumulates in the containment area shall be at a minimum, visually observed prior to release of the
accumulated storm water. Accumulated storm water shall be released if found to be uncontaminated. Records
documenting the individual making the observation, the description of the accumulated storm water and the date and
time of the releases shall be kept for a period of 5 years.
All outdoor bulk storage containers are double walled for containment and safety purposes. In addition, trenching
surround the storage containers to provide additional containment in the event of a spill or leak. Bulk storage
containers located within buildings at the mill are either double walled or utilize the building structure to provide
containment in the event of a spill or leak and protect water quality.
In appendix D of this plan is a list of the Section 313 water priority chemicals. if any additional chemicals are stored
outside in the future, secondary containment must be provided.
The following water priority chemicals are on site at the Nucor facility:
CAS NUMBER
COMMON NAME

Xylene (Paint Thinner)
7440-66-6
Zinc (EAF Dust)

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 filter strips, infiltration, storm water 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 storm water discharges and data collected through monitoring and auditing.
Good Housekeeping:
The existing housekeeping practices observed at the Nucor facility are generally very good. In general the facility has a
large amount of material stored outside. The material should not have a negative impact upon surface waters. In
addition, much of the material is being stored temporarily awaiting processing or shipment. However, the volume of the
material stored outside increases the likelihood that an item placed outside in the future may impact surface
waters. Therefore, ensuring that any material or scrap metal that is stored outside is free from radiation and is as clean
as possible, though not a requirement of the SP3 plan, is a good long term material management strategy. The scrap
management plan is located in Appendix E.
Minimize the quantity of pallets, equipment, and other materials stored outside to maximum extent possible.
Ali drums containing any chemical, oil, fuel, or hazardous waste shall be properly secured and labeled.
Trash dumpsters on the site will be routinely pulled before the contents spill out. Free liquid material shall not be placed
in these dumpsters.
Toxic and hazardous materials shall be stored inside, if safety provisions allow, or in a covered area.
The facility should be kept clean by regularly picking up trash and litter.
The facility shall use fertilizer, herbicide and pesticides in a judicious manner to prevent overuse of these materials.
Paved areas should be swept on a regular basis. Dust control such as water and asphaltic emulsion shall be applied to
unpaved travel roads as needed.
Pollution prevention concepts shall be regularly publicized to employees.
Painting Operations:
• Inspect and properly prepare parts for painting.
• Contain and properly dispose of or reuse sanding and sandblasting materials where possible.
• Prevent paint waste from contacting storm water.
• Properly store paint and solvents under cover.
• Make sure paint equipment is operating efficiently and does not leak.
• Recycle paint, paint thinner, and solvents.

It's Our 1\7ature'
Environmental Management 5ystem: We Do It Right -- It's Our Nature
Vehicle and Equipment Washing:
• Oily equipment and vehicles are not to be washed or steam cleaned outside without appropriate controls for
wash waters.
• Use phosphate free biodegradable detergents.
• Wash over impervious surfaces.
Loading and Unloading Materials:
• Loading areas should be swept on a regular basis.
• Grade, berm or curb area around loading area to prevent storm water runoff contamination.
• Inspect trucks for leaks.
• Clean loading areas of accidental spills immediately.
Outside Storage of Raw Materials, By -Products or Finished Products:
• Store all materials indoors to the extent practicable.
• Prevent storm water runoff by enclosing area or building a berm around the area.
Preventative Maintenance:
Containment berms and aboveground storage tanks should be inspected monthly for leaks, cracks, and other signs of
deterioration.
Material storage areas should be inspected monthly for corroded and damaged drums, boxes, crates, and bags, or other
potential causes of leaks and spills. Items identified should be repaired or contained, and any spillage immediately
cleaned up.
A preventative inspection and testing program shall be developed for all major equipment use or stored outside
(including vehicles) that could lead to storm water runoff contamination. The program shall include:
Service checklists and maintenance logs for each piece of equipment.
Employee education and instruction materials; and

Vehicle and Equipment Maintenance:
• Prevent spills and drips of solvents and cleaners on the shop floor.
• Check for leaking oil and fluids.
• Use nontoxic or low toxicity materials and solvents when possible.
• Use recycled or recyclable products when possible.
• Avoid hosing down work areas unless spilled materials are cleaned up first.
• Do not pour liquid waste in floor drains, sinks, or outdoor storm drains.
• Drain oil filters before disposal or recycling.
Spill Prevention and Response:
Facilities should adopt spill control measures that require repair of any damaged container prior to outdoor transport
and immediate cleanup of spilled material to the greatest extent possible.
Any observed leak or spill should 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 an 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 of.
An adequate amount of dry absorbent should be stored near fuel pumps, tanks, and other areas prone to spills, and
used as needed to contain and cleanup spills.
Berms and curbing may be constructed to contain areas prone to spills.
Proper compatible storage containers should be used for materials stored outside. Any damaged containers should be
repaired or the materials in the damaged containers transferred to a new undamaged container. All containers should
be clearly labeled.
Drums containing liquids, including oil and lubricants, shall be stored indoors, in a bermed area; in overpack containers
or spill pallets; or in similar containment devices.
Where practicable, a containment system such as a concrete pad or double walled tanks shall be provided around all
tanks/containers located outside.
Where practicable a containment system such as a concrete pad with berms -shall be provided under the hydraulic
systems of equipment located outside.
Special care should be taken to prevent and immediately clean up any leaks or spills that occur in recessed loading dock
areas that drain to a sump. The sump water should, where practicable, be discharged to the.facility's water treatment
plant or sanitary sewer (with permission).
Absorbent pads and blankets may be placed in, or around, storm drains to collect sediments and oily substances.

Liquid Storage in Aboveground Tanks:
• Comply with existing spill prevention, cleanup and countermeasures plans (SPCC) and incorporate by reference.
• Employ engineering safeguards to prevent accidental releases of pollutants.
• Install overflow protection devices on tank systems to warn operator or to automatically shut down transfer
pumps when tank reaches full capacity.
• Place protective guards around tanks and piping to prevent vehicle or forklift damage.
• Clearly tag or label valves to reduce human error.
• Visually inspect tank system to identify problem areas.
• Provide secondary containment system around both permanent and temporary tanks.
Fueling Stations:
• An automatic shut-off device should be installed on all gasoline and diesel fuel pumps.
• Install spills and overfill prevention equipment on fuel storage tanks and pumps.
• Avoid "topping off' vehicle fuel tanks.
• Paving fuel areas with concrete, where possible.
• Covering fuel areas with roofs, where possible.
Grading, berming or curbing fueling area to avoid storm water runoff.
• Store sorbent material near fueling areas to absorb spills.
Sediment and Erosion Prevention:
The topography at the Nucor facility is primarily flat with dense vegetation typical of the North Carolina coastal region.
Unpaved yard/operation areas should be periodically re -graded to prevent the formation of ruts and gullies. Gravel and
stone aggregate placement at the sites should be coarse, with a minimum amount of fine particles, which would be
easily flushed by runoff.
A good vegetative cover should be maintained in non -operational unpaved areas.
Any observed erosion, scouring or sedimentation should 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.

Implement Best Management Practices
Use BMPs as a guide for housekeeping, maintenance, and operation to prevent storm water pollution.
Employees shall be given annual awareness training. New employees shall receive storm water pollution prevention
training as part of their orientation program.
The storm water pollution prevention team shall periodically meet and review the SWPPP.
The storm water pollution prevention team will submit all recommendations to the Team Leader for evaluation.
The storm water pollution prevention team recommends that at least 1-2 associates be employed full time at the facility
for cleanup.
The storm water pollution prevention team recommends proper training and inspection to ensure compliance with
guidelines for storm water.
Management of Runoff
Management of runoff involves storm water treatment measures. Source reduction and containment/diversion BMPs
are preferred to storm water treatment. Even though most of the storm water issues at Nucor are well suited to source
reduction and containment/diversion BMPs, storm water treatment is provided as an additional source of control to
ensure protection of water quality.
Nucor's storm water system exceeds all State requirements. The storm water 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`Yo 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.

Spill Prevention and Response Plan
The Permit requires that this plan incorporate a risk assessment of potential spill sources to surface waters based on the
materials inventory of the facility. The permit also requires that a responsible person shall be on site at all times during
facility operation that have the potential to contaminate storm water. The most significant potential spill source to
surface waters at Nucor is from the bulk storage tanks and material handling operations. In the event that a spill of
sufficient quantity occurs outside or that reaches the outdoors, the spill would be channeled to the storm water system
described earlier. There is sufficient capacity and residence time to contain any spill prior to it reaching surface
waters. Operating procedures are in place so that, if necessary, any spill could be contained in the forebays to the storm
water ponds.
Spill Prevention Control and Countermeasures Program
In order to prevent accidental spillage of cleaning components, additives, maintenance and water treatment chemicals,
the following steps will be taken.
1. All chemicals will be stored in the appropriate storage area until needed.
2. Chemicals will not be moved from the storage area until needed. They will then be placed within the contained
area at the proper location.
3. All associates will be familiar with spill control and countermeasures.

Preventive Maintenance
The permit requires the development of a Preventative Maintenance Program to document schedules of inspections
and maintenance activities of storm water control systems, plant equipment, and systems. Preventative maintenance
should be performed at all areas where good housekeeping practices can minimize exposure to storm water. The
Preventative Maintenance Program is built around the premise that areas with a potential for significant exposure to
storm water should be inspected on a semi-annual basis. The inspection and maintenance activities are explained in
more detail below.
The storm water drainage system should be inspected semi-annually for the following:
1. The drainage pathways should be inspected for the presence of dry weather flow. If dry weather flow is
observed, the flow should be traced to determine the source.
2. Basins should be inspected for objects that may block flow and for signs of non -storm water discharges such as
oil stains.
3. The building perimeter should be inspected for additional pipe penetrations.
4. The drainage system should be inspected for signs of soil erosion.
5. Inspect all outdoor handling, storage, and other operations to ensure that the material exposed to storm water
is clean and does not have significant materials/chemicals on the surface, which may contaminate the storm
water.
Appendix G contains an inspection and maintenance form that can be used to document the results of the semi-annual
inspections. The form should be placed into the SP3 files and be readily available.
Good Housekeeping
Nucor conducts monthly housekeeping and safety inspection of the entire facility. This is done to help insure the facility
is kept clean, safe and environmentally sound. These inspections are documented and kept on the computer for
use. These inspections are conducted by a manager and supervisor each month.

2. Familiarize employees with past spill events -why they happened and the environmental impact.
3. Post warning signs in spill areas with emergency contacts and telephone numbers.
4. Drill on spill clean-up procedures.
5. Post the locations of spill clean-up equipment and the person responsible for operating the equipment.
Materials Handling and Storage
1. Be sure employees are aware which materials are hazardous and where these materials are stored.
2. Point out container labels.
3. Tell employees to use the oldest materials first.
4. Explain recycle practices.
5. Demonstrate now valves are tightly closed and how drums should be sealed.

Nucor Steel — Hertford County
Pollution Prevention/Scrap Management Plan for the Control of Contaminants in Scrap
under the Area Source Rule for Electric Arc Furnace (EAF) Steelmaking Facilities
Contaminants such as chlorinated plastics, free organic liquids, lead (except for leaded steel) and
mercury are not appropriate or desired for the production of steel in EAF facilities. However, these
contaminants are found in the scrap metal that is the basic feedstock for the production of new steel.
EPA has identified EAF facilities as potential sources of HAP emissions and, on December 28, 2007,
promulgated final regulations (codified at 40 CFR Part YYYYY) intended to control or minimize such
emissions.
The regulations require EAF facilities, among other things, to restrict the use of certain scrap or follow a
pollution prevention plan (PPP) for scrap purchased as production feedstock to minimize the amount of
specified contaminants in such scrap.
Nucor Steel - Hertford County ("Nucor") is committed to complying with the requirements of the EAF Area
Source Rule and to the goal of removing at least 80% of mercury convenience -light switches from motor
vehicle scrap. Nucor is also committed to minimizing to the extent practicable the presence of other
contaminants in scrap that may result in the emission of hazardous air pollutants (HAP).
Accordingly, Nucor has adopted and will comply with the provisions of this PPP designed to control the
presence of such contaminants in scrap that is consumed in the EAF by adopting:
1. A specification for scrap that addresses contaminants identified by EPA
2. Procedures for verifying compliance with the specification
3. Procedures for taking corrective action against vendors who do not comply with the specification
4. Program policies, implementation elements, and training and outreach materials sufficient to
demonstrate how Nucor will appropriately implement its responsibilities under the EPA approved
National Vehicle Mercury Switch Recovery Program (NVMSRP) or other EPA approved program.
The terms used in this Pollution Prevention Plan and in the outreach materials attached and
incorporating to the PPP shall have the same definitions as those enumerated in EPA's Final Area Source Rule
found at 40 CFR Part 63 Subpart YYYYY. As outlined in the final rule, the term "mercury switch" denotes
only mercury switches that are part of a convenience light switch mechanism installed in a vehicle.
I. General Scrap Specifications:
UNCONTROLLED DOCUMENT IF PRINTED

It's OurAfature`4
Environmental Management System: We Do It kight - Et 5 Our Nature
The following restrictions apply to all scrap steel purchased or used by Nucor in its EAF steelmaking process:
A. Scrap materials must be depleted to the extent practicable of undrained used oil filters, chlorinated
plastics, and free organic liquids at the time of charging to the furnace.
B. Lead -containing components of scrap, such as batteries, battery cables, and wheel weights, must be
removed, to the extent practicable, prior to charging in the furnace unless the scrap is used to produce
leaded steel.
C. Motor vehicle scrap must be purchased from providers that have minimized the presence of mercury in
scrap through participation in the NVMSRP or another EPA -approved program.
IL Verification of Compliance with Specifications
A. Free Organic Liquids, Chlorinated Plastics, Lead and Lead -Containing Components:
a. Visual Inspection: Nucor conducts a visual inspection of incoming scrap loads to ensure that the
scrap meets existing quality and/or purchase order specifications for grade, type, density, and
content. Scrap inspection will be required also to determine whether there is an obvious presence
of free organic liquids, chlorinated plastics, or lead -containing components. Records of scrap
inspections will be maintained on site for one year. Scrap inspection records shall include the
identity of the scrap provider for any load that fails visual inspection. Foreign materials will be
removed to the extent practicable prior to charging to the furnace, and the scrap supplier will be
subject to corrective action.
b. Inspection for Free Organic Liquids: Turnings, borings, and other forms of scrap that were
generated as a result of the processing of metal with use of cutting, lubricating or cooling fluids
will be visually inspected prior to charging to the furnace to ensure that such scrap does not
contain free organic liquids.
c. Depletion of Lead and Chlorinated Plastics from Shredded Scrap: Scrap that has been processed
through a shredder that utilizes magnetic or density separation techniques to separate ferrous and
non ferrous materials will be presumed to be depleted scrap of chlorinated plastics and lead to
the extent practicable.
d. Inspections: Nucor shall identify any scrap provider whose scrap (except as described in
Paragraph (e) below) is not subject to inspection pursuant to this plan. Nucor shall audit or
inspect the facilities from which such uninspected scrap is provided on a periodic basis at a rate
of not less than 10-25% of such facilities each year.
e. Unrestricted Scrap: Certain types of scrap, including "factory bundles," "demolition debris,"
"home scrap," "return scrap", "rail," and "flashings," as defined by common industry practice, as
well as similar uncontaminated scrap, are not expected to contain free organic liquids,
chlorinated plastics, or lead and will be presumed to be free of these contaminants. This scrap is
not subject to the inspection and verification requirements of this plan.
f. Baghouse Bags, Internal Process and Maintenance Materials: Baghouse bags and baghouse
maintenance materials that are routinely recycled by charging to the electric arc furnace,
including personal protective equipment (PPE) and baghouse dust, are exempt from this PPP and
not subject to the inspection and verification requirements of this plan.

it's Our Aature.�*�
Environmental Management System: We Do It Right - R 5 Our Nature
B. Mercury
a. Nucor shall ensure that motor vehicle scrap providers are participating in the National Vehicle
Switch Recovery Program (NVMSRP) by conducting a review of the End of Life Vehicle
Solutions (ELVS) database to confirm that the motor vehicle scrap provider is enlisted as a
participating member. Nucor will conduct a semi-annual review of the ELVS database to
determine whether the provider remains identified as an NVMSRP participant;
i. Nucor may not be able to confirm that some motor vehicle scrap providers such as
Brokers are enlisted as a participating member in the NVMSRP through the ELVS
database. In these cases Nucor will confirm that the broker is participating in the
NVMSRP or another EPA -approved program by obtaining from the broker written
assurance that any motor vehicle scrap provided by such broker to Nucor was procured
from other suppliers who are signed up for and are participating in the NVMSRP or
another EPA -approved program;
ii. Nucor will require motor vehicle scrap brokers to confirm such written assurance on a
semi-annual basis.
b. Nucor will conduct a semi-annual review the ELVS database to corroborate that the participant is
implementing appropriate steps to minimize the presence of mercury in scrap from end -of -life
vehicles by turning in mercury switches.
i. Some motor vehicle scrap providers participating in the NVMSRP or another EPA -
approved program may not be able to demonstrate their participation in NVMSRP or
another EPA -approved program to minimize the presence of mercury in the motor
vehicle scrap from end -of -life vehicles by turning in mercury switches because they
refuse to accept motor vehicle scrap that contains mercury switches. Examples would be
a broker who purchases motor vehicle scrap from program participants, or a shredder that
accepts only flattened vehicles from which the mercury switches already have been
removed to the extent practicable prior to delivery to the shredder. For these motor
vehicle scrap providers, Nucor will obtain written assurances from the provider or obtain
other means of corroboration to verify that the participant is implementing appropriate
steps to minimize the presence of mercury in the scrap from end -of -life vehicles. Written
assurance will be confirmed on a semi-annual basis.
c. If a motor vehicle scrap provider does not participate in or demonstrate through written
assurance that it purchases motor vehicle scrap through NVMSRP or another EPA approved
program for the removal of mercury switches, Nucor shall only purchase motor vehicle scrap
from such provider pursuant to an EPA -approved facility -specific program for the removal of
mercury switches.
III. Corrective Action
A. Lead, Chlorinated Plastics, Free Organic Liquids
a. If, during inspection of scrap pursuant to Part II(A) above, Nucor determines that the scrap
provider has not met the specifications in part I, the scrap provider will be subject to corrective
action.
i. A nonconforming scrap load will be rejected unless contaminants causing the failure can
be removed to the extent practicable. The vendor may ship Unrestricted Scrap so long as
it adheres to the provisions outlined in Part II(A)(e).
UNCONTROLLED DOCUMENT IF PRINTED

It's OurNlature`.r d
Environmental Management System: We Do It Right - It's Our Nature
ii. After a failure to meet the scrap specifications in Part I, the scrap provider must sign a
statement acknowledging the requirements of the scrap specifications and provide either
certification or another comparable form of reasonable assurance that the scrap
specifications will be met in the future.
iii. If the vendor continues to fail to meet the scrap specifications, Nucor will consult with
the scrap provider on the cause or reasons why the scrap loads are nonconforming and
will inform the scrap provider that it may be suspended (for a period to be determined on
a case -by -case basis) if the problem is not resolved.
B. Mercury
a. If Nucor reasonably believes, either as a result of inspection, site visits to a scrap yard, or review
of the ELVS database or by other means, that a scrap supplier is not taking appropriate steps to
minimize the presence of mercury switches in scrap from end -of -life vehicles, the facility shall:
i. Issue a letter to the scrap provider reiterating the requirements of the NVMSRP or
another EPA -approved program and threatening suspension if the scrap provider fails to
fulfill its responsibilities under the NVMSRP or another EPA -approved program.
ii. Suspend the scrap provider if, within six months of receipt of the letter described above,
the scrap provider again fails to show that it is aware of the need for and is implementing
appropriate steps to minimize the presence of mercury switches in auto shred. The
suspension shall only apply to shipments of motor vehicle scrap. The provider will then
have to re -qualify by demonstrating that it has cured the defect that caused the failure to
meet the scrap specification.
iii. For purposes of Section III A and B, if the nonconforming scrap is purchased through a
broker, Nucor will require the broker to provide written assurances that the broker
implemented corrective action as set forth in Section III of this plan with respect to the
supplier of such non -conforming scrap.
IV. Program Policies, Implementation Elements, and Training and Outreach Materials
A. The following materials are hereby incorporated by reference into this plan.

Dear Mr. Diggs,
This letter is in response to your request for additional information. The reason that we did not
submit a narrative on any significant changes is that we are a new facility and we -have made no
significant changes since start-up in 2000. Our industrial activities, work processes, material
handling practices, material storage processes, and raw materials used are all the same as
represented in the original permit. Our equipment is relatively new and Best Management
Practices (BMPs) were implemented during start-up and have changed very little since that time.

Hi Terry,
The final NPDES stormwater permit has been issued for the Nucor Steel facility in Cofield, NC. It will be effective as of
August 1, 2016. There was one major change from the draft permit which was to remove the silver parameter from
analytical monitoring requirements.
A hard copy is in the mail to Robert McCracken, along with some extra monitoring forms. I've attached a scan of the
final permit, cover letter, and monitoring forms to this email. Responses to your questions are below in red.

Thanks for the opportunity to review the draft permit. We probably have more questions than corrections, to help us
understand how to comply with the new permit. I will try to keep them brief and will follow-up with a telephone call
and I'm sure that David May's visit will help also. With that in mind, I am copying David May, because of the compliance

Part II, Section B
a. "measurable storm events" vs. "representative storm events"
i. The new definition refers to, "...a storm event that results in an actual discharge from the
permitted site outfall." This gets a little tricky with our storm water ponds.
1. If we have been a long period without rain, we could have a significant rainfall event and
still not have flow through the outfall.
2. On the other hand, if our ponds are full and the ground in the area is saturated, we may
discharge for a long period of time without any rainfall
3. This makes it tough to tell when a rainfall event results in an actual discharge. Sampling
within the first 30 minutes of a discharge from the pond is okay. If the pond doesn't
discharge, then sampling at that outfall is not required.
ii. The old definition referred to a rainfall event of 0.1" or more.
1. The old definition was better from the standpoint of determining a significant rainfall
event.
2. While there are times when a 0.1" rainfall will not result in flows, usually this is a good
indicator for our location
3. Less than this is probably would not result in flow through our ponds If the pond
doesn't discharge, then sampling at that outfall is not required.
iii. While the new definition doesn't specify an rainfall amount, are there any concerns with us
continuing to use this definition? We made this change to all permits in order to include sites
with small drainage areas that can see flow even with rainfalls less than 0A." But if 0.1" is a
good indicator for when your site will have a discharge, then it makes sense for you to continue
to use that definition.
b. Table 1, Footnote 2. Grab samples shall be collected within the first 30 minutes of discharge.
i. Concerns
1. We may have continuous flow throughout the entire year from some of these ponds (It
is hard to determine when a storm event reaches the outfall)
2. We operate 24/7, 364 (We takeoff Christmas Day)
a. Many storm events occur at night and this posses a hazard accessing these
outfalls in the dark
b. If we collect a sample on a weekend or even a Friday, we exceed the holding
times, due to shipping
3. We normally look for a rainfall event Sunday night to Wednesday morning (So that the
sample shipping works for holding times)
The following section that states, "Sampling is not required outside the facility's normal
operating hours."
iii. Possible solution:
1. Our office hours and the normal hours for the individual taking the samples is M-F
07:00-16:00.
2. Due to the retention time that our ponds create, it realistically take more than 30
minutes for first flush to reach the outfalls
3. If we sample during the office hours following a measurable storm event, we should be
able to capture actual storm flow and meet the required sample holding times. Ok
2. Section B, Table 3 Benchmark Values for Analytical Monitoring
a. Copper, Lead & Zinc benchmarks were eased shouldn't be a problem
b. Non -Polar Oil & Grease

i. This is a new method and it is half of our existing limit
ii. Based on past monitoring, this should not be an issue
iii. We need to discuss with our lab
e. _Zinc, total Fe Fable ilver
L This is 30% of our current detection limit
ii. Based on current detection limit, we do not know how this will affect us
iii. We need to discuss with our lab
iv. What is the basis for this significant change? The benchmark for silver was changed to reflect
Final Acute Value (FAV) plus a safety factor. The FAV is estimated by a statistical analysis of
acute toxicity data and protects 95 percent of the species tested.
v. What do you see as the source for Silver in storm water? In general, silver can be found in
'stormwater coming off coal piles, diesel fuel, various other types of industrial waste piles.
vi. As far as I am aware, we shouldn't have any Silver about naturally occurring levels. Because
silver is not part of your process, there are no exposed coal piles, and silver levels were below
detection limits in nearly all samples, we have removed this parameter from your revised
permit.

Dear Mr. McCracken:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please
review the draft carefully to ensure thorough understanding of the conditions and
requirements it contains. .
The draft permit contains the following significant changes from the facility's current permit:
1. You are required to collect analytical and qualitative monitoring samples during
"measurable storm events" as defined in Part II, Section B. This term is different
from the "representative storm event" in earlier permits.
2. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part II,
Section A.
3. Changes have been made to six monitoring parameters, including.a change to five
benchmarks. Stormwater benchmarks are not permit limits, but rather guidelines for
implementing the Stormwater Pollution Prevention Plan (SPPP). A benchmark
exceedance is not a permit violation; however, the permittee must respond to
exceedances as directed in the Tiers.
The Oil & Grease parameter is changed to Non -polar Oil & Grease [EPA
Method 1664 (SGT-HEM)]; the benchmark for Non -polar Oil & Grease is 15
mg/L.
• The benchmark for Capper is changed from 0.007 mg/L to 0.010 mg/L.
• The benchmark for Lead is changed from 0.003 mg/L to 0.075 mg/L.

• The benchmark for Silver is changed from 0.001 mg/L to 0.0003 mg/L.
• The benchmark for Zinc is changed from 0.067 mg/L to 0.126 mg/L
• Vehicle maintenance monitoring parameters have been revised as follows:
o Non -Polar Oil & Grease [EPA Method 1664 (SGT-HEM)] replaces
Oil & Grease/TPH. This requirement appears in all individual
stormwater permits; however, it only applies to facilities that
perform onsite vehicle maintenance activities. If the facility begins
vehicle maintenance during the permit cycle, the requirements shall
apply.
o pH monitoring is no longer required for discharges only associated
with vehicle maintenance activities.
4. A new section on Special Conditions has been added in Part II, Section E to comply
with federal regulations requiring electronic submittal of discharge monitoring
reports. This section of the permit will become effective December 21, 2016.
Please review the draft permit and submit any comments to me no later than 30 days
following your receipt of the draft. Comments may be emailed to me at

Dear Mr. McCracken:
In response to your renewal application for continued coverage under NPDES storrnwater permit
NCS000379, the Division of Energy, Mineral and Land Resources (Division) is forwarding herewith the
subject state - NPDES permit. This permit is issued pursuant to the requirements of North Carolina General
Statute 143-215 .1 and the Memorandum of Agreement between North Carolina and the U.S:
Environmental Protection Agency dated October 15, 2007 (or as subsequently amended).
This final permit includes one major change from the draft permit sent to you on April 8, 2016. The
silver parameter has been removed from your permit. It is our understanding that silver is not a part of your
facility's process, and there are no exposed coal piles which can leach silver. Further, silver levels were
below detection limits in almost all of the 30+ samples taken between 2002-2013.
The monitoring strategy remains the same (semi-annual) as the previous term of the permit. Please note
that analytical and qualitative monitoring is required in this permit. Failure to complete the monitoring as
required is a violation of the permit and any permit noncompliance constitutes a violation of the Clean
Water Act. Reference Part III, Section A, Item 2 "Duty to Comply", Item 9 "Penalties for Tampering" and
Item 10 "Penalties for Falsification of Reports" of your permit for further information.
If any parts, measurement frequencies or sampling requirements contained in this modification are
unacceptable to you, then you have the right to file a petition for a contested case with the Office of
Administrative Hearings within thirty (30) days following receipt of this letter. This petition must conform
to the requirements of Chapter 150B of the North Carolina General Statutes. Petitions must be timely filed
with the Office of Administrative Hearings, Post Office Drawer 11666, Raleigh, North Carolina 27604. If
you do not file a petition within the required time, the agency decision shall be final and binding.
Please take notice this permit is not transferable. Part III, B.2. addresses the requirements to be followed in
case of change in ownership or control of this discharge. This permit does not affect the legal requirements
to obtain other permits which may be required by this Division, or permits required by the Division of
Water Resources, Coastal Area Management Act or any other federal or local governmental permit that
may be required.

And new coal pile
Stormwater discharge permit
Nucor Steel - Hertford County
Thank you for your letter of December 15, 2005. We appreciate your notification of a change in
activity at the subject site, including your planned new coal pile. You also specifically requested
confirmation from us concerning continued sampling. We have several comments related to the
points presented in your letter.
1. As to the change in operation, please note that coal pile runoff is a wastewater, and
consequently its discharge is not permitted under your stormwater permit, NCS000379.
You will need to obtain NPDES wastewater permit coverage for any discharge of coal pile
runoff.
2. As to your request for confirmation of DWQ's expectation with regard to continued sampling
beyond the fourth year of the permit, the permit language does appear to omit fifth year
sampling. DWQ's preference would be that Nucor to revert to annual sampling in the fifth
year of the expired permit, and our expectation is that Nucor will continue with annual
sampling after that until we have worked through our backlog and renewed NCS000379.
3. You report that Nucor "has continued to operate and comply with the 2000 permit while
awaiting a final action on its pending permit renewal application." Based on your timely
renewal application, your expired permit continues in effect until we can renew it. With the
exception of the fifth year sampling, it appears that Nucor has approached its continuing
obligation under NCS000379 in accordance with DWQ expectations.
Please contact me with any questions or comments.

Re: Notification of Process Change
NPDES Stormwater Permit Number NCS000379
Dear Mr. Pickle:
We are writing this letter to notify the Stormwater and General Permits Unit of Nucor
Steel — Hertford County's (Nucor's) planned change in operation which may potentially affect
discharges authorized by its NPDES Storm Water Permit at the facility. Specifically, Nucor
Tans to store coal in a small uncovered coat pile at the facifily. In addition, Nucor is seeking
confirmation that it has met sampling requirements imposed under the 2000 NPDES permit and
that it is not required to conduct additional monitoring
As you are aware, Nucor obtained NPDES permit number NCS000379 which became
effective on June 1, 2000 and expired on May 31, 2005 (the 2000 permit).. Nucor submitted a
timely permit renewal application on November 19, 2004 which the Department deemed
complete in December, 2004. At the Department's instruction, Nucor has continued to operate
and comply with the 2000erm1t while awaiting a final action on itspending permit renewal
application_
Notification of Coal Pile Storage
Until now, Nucor has stored coal in a covered storage area which precluded precipitation
and runoff from contacting the coal. Nucor is now planning to expand the facility's coal storage_
capacity, which requires that coal be stored in an uncovered area approximately sixty feet by
eighty feet at the facility. The coal pile is located east of the main substation, which drains to the
west. Nucor is in the process of updating its Storm Water Pollution Prevention PIan (SWPPP) to
include best management practices for coal pile runoff reduction and management. These
practices include constructing a berm around the coal pile storage area to minimize the potential
amount of stormwater contacting the coal pile and constructing a stormwater ditch west of the
coal pile storage area to capture all runoff from the coal pile. The stormwater ditch is designed
with a check dam prior to discharging into the rest of the facility's stormwater management
system in order to reduce the amount of solids in the discharge.

Analytical Monitoring Since Expiration of the 2000 Permit
As stated above, Nucor was told by the Department to continue to comply with the
conditions set forth in the 2000 permit in effect at the time of the permit expiration until the
Department has taken a final action on the permit renewal application. Under Part RD of the
2000 permit, analytical monitoring was to be conducted annually in the first, second and third
year of the permit and quarterly in the fourth year. Nucor complied with these monitoring
requirements and submitted the appropriate data to the Department. However, there is no
analytical monitoring requirement for the fifth year of the permit (i.e., from June 1, 2004 to May
31, 2005). Nucor therefore has interpreted the permit as not requiring further analytical. -'sampling
in the fifth succeeding year. Hence, no analytical monitoring has been conducted while Nucor
awaits its permit renewal. Nucor has continued to conduct the qualitative monitoring, as
required under the permit. Nucor seeks confirmation that this is the Department's intended
interpretation. �^
As always, please contact me if you have any questions regarding the expansion of the
coal pile storage area. Also, please confirm our understanding that Nucor is not required to
conduct analytical monitoring while it is awaiting the issuance of its permit renewal. We look
forward to hearing from you.

Brian,
Below is a short description of our facility including some changes in operation that are in the works. If
you get the opportunity, I encourage you to pay us a visit. A few hours on -site will assist you in
understanding our operation more than days of correspondence.
If you do have more questions, you can contact me or Elizabeth, our Environmental Engineer.

Nucor Steel — Hertford County is a steel recycling facility that receives scrap steel, alloys
and other raw material. These materials are stored and then charged to an electric arc
furnace (EAF) that melts the steel. We then tap the molten steel from the EAF into a
ladle, transfer it to a ladle metallurgy furnace (LMF) to adjust the chemistry then transfer
it again to a continuous caster where we cast 6" slabs up to 10' wide. The slabs are
then reheated to the proper temperature and hot rolled to produce plate steel 3/8" to 2"
thick. The plates are then leveled, sheared and shipped as discrete plate via truck and
rail car. Other activities on -site, include vehicle maintenance, slag and mill scale
processing and other general maintenance and repair.
The facility is located on 984 acres in the Chowan River Basin. We have constructed
four storm water ponds that drain 517 acres, encompassing the developed portion of the
property. The remaining 467 acres are undisturbed areas consisting mostly of
woodlands and preserved wetlands. These undisturbed acres do not drain to the storm
water ponds.
Changes in Operation
We have submitted an air permit application (PSD) for a plate heat treating facility that
will have an annual capacity of 120,000 tons. The heat treat line will include a natural
gas -fired austenitizing furnace (36 MMBtu/hr), a natural gas -fired tempering furnace (37
MMBtu/hr), a shot blaster, two plate cutting bed systems and a cooling tower (3,000
gallons per minute). As part of the same permitting process, we are seeking an increase
in allowed slag processing from 262,000 tons per year to 360,000 tons per year.

2. General Observations:
3. Impairment: The site is on the 25a2b section of the Chowan River -and is not rated for the aquatic life rating.
The Chowan River (25al) is on the 303d list for a Standard violation: low dissolved oxygen and a fish advisory:
Mercury. Possible sources are agriculture and intensive animal feeding. operations. The Chowan River 25a2 is
on the 303d list for a fish advisory: Mercury. Possible sources are industrial, municipal and atmospheric
deposition. The Chowan River (25b, 25c) is on the 303(d) list for Historical Listing decision: Nutrients. Chowan
Basinwide Plan recommendation for 2007: DWQ.recommends that the upper Chowan River [AU# 25a1I be -
removed from the 2008 303(d) list of impaired waters for water quality standards. Ambient monitoring indicates
that no criteria, were exceeded beyond natural conditions. Benthic sampling also shows that the biological
community has improved since the previous assessment period.
4.. Threatened and Endangered: Based on the Natural Heritage Virtual Workroom there are no federally threatened.
or endangered -species within 2 miles of the facility. .
5. Location: -The outfalls are located at a B; NSW and a C; NSCW.
6. Industrial Changes Since Previous Permit: There have been no changes since start-up in 2000. (Based on a letter
December 15, 2004) ;
On December 15, 2005, Nucor submitted a letter to Ken Pickle explaining the addition of Coal Pile Storage.
Nucor used to store coal in a covered storage area which precluded precipitation and runoff from contacting the
coal. Nucor is planning to expand the facility's coal storage capacity, which requires that coal be stored in an
uncovered area approximately sixty feet by eighty feet at the facility. A stormwater ditch was designed with a
check dam prior to discharging into the rest of the facility's stormwater management system in order to reduce
the amount of solids in the discharge. Update: The coal pile was not put outside (April 2009).,
Changes in Operation
We have submitted an air permit application (PSD) for a plate heat treating facility that will have an annual
capacity of 120,000 tons. The heat treat line will include a natural gas -fired austenitizing furnace (36 ,
MMBtu/hr), a natural gas -
fired tempering furnace (37 MMBtu/hr), a shot blaster, two plate cutting bed systems
and a cooling tower (3,000 gallons per minute). As part of the same permitting process, we are seeking an
increase in allowed slag processing from 262,000 tons per year to-360,000 tons per year.
7. Analytical Monitoring Notes: Analytical monitoring included pH, Oil and Grease, BOD, COD, TSS, TKN,
Nitrate plus Nitrite Nitrogen, Total Phosphorus, Lead, Zinc, Barium, Magnesium, Manganese, Beryllium,
Cadmium, Thallium, Copper, Mercury, Selenium, Silver, Phenols, Naphthalene, Trichloroethylene, Antimony,
Arsenic, and Tetrachloroethylene. Sampling was to be done annuallyfor'the first 3 years and quarterly during
the fourth year.. Eight different samples were taken at each outfall Al and A3. Ten samples .were taken at
outfall B1 and eight samples were taken at outfall Cl._ At each outfall there were a couple values that were
outside the current benchmarks for pH and Copper.
The facility is included in the EPA multi -sector general permit for SIC 3312 under Sector F: Primary Metals.
The monitoring recommendations are total aluminum and total zinc'.
Maintain monitoring for pH, COD, TSS, Nitrate -Nitrite, P, Oil&Grease, Antimony, Copper, Lead, Magnesium,
Mercury, Silver, and Zinc. BOD, TKN, Phenol, Arsenic, Barium, Beryllium, Cadmium, Manganese, Selenium,
Thallium, Napthlene, Trichloroethylene; and Tetrachloroethylene have been removed from the monitoring. The
parameters were removed from the monitoring because the reported data were either not detected or less than
Page 4 of 9

NCS000379
Revised Permit Recommendations: Analytical Monitoring:
1. Maintain monitoring for pH, COD, TSS, Nitrate -Nitrite, P, Oil & Grease, Antimony, Copper, Lead, Magnesium,
Mercury, Silver, and Zinc. BOD, TKN, Phenol, Arsenic,. Barium, Beryllium, Cadmium, Manganese, Selenium,
Thallium, Napthlene, Trichloroethylene, and Tetrachloroethylene have been removed from the monitoring.
2. All analytical monitoring has been set to semi-annually during a representative storm.event as defined in Part lI
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" 30 days -
of the end. of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2.
3. Benchmarks for analytical monitoring have been added to this draft permit. 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. If the sampling results are above -a.
benchmark value', or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier I guidelines, which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the.benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier I and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples. .
4. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of representative
outfall status.
5. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall. parameter is in
this permit, however.)
7. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan. requirements. The site map must now identify if the
receiving stream is impaired and_if it has a TMDL established. It must also describe potential pollutants in'cach
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part lI Section
A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part U. Section A. More
details regarding secondary containment are provided.
3. AdditionaI requirements for the Stormwater Pollution Prevention Plan have been -specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify.that the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater .
Management controls as'specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft 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 Exclusion from NPDES stormwater discharge permit requirements. Additional information
is provided in Part I Section A.

Discussions with permittee: Giffin Daughtridge — moved to a different facility, talked with Terry Hairston,.
Environmental Manager, 252-356-3700, 4/15/09
1. General description of on site industrial activities? Steel Recycling facility. Use electric arc furnaces and
produce steel plats. Bring is scrap that is stored outside. 1.6 million tons of end product were produced last
year.
2. Have there been any changes since the application was filed? No. However, the proposed coal pile was not put in
outside but under roof. A heat treat facility is planned that will include two small natural gas furnaces that will be
located under roof.
3.. Where is the stormwater from the coal pile going? A letter was sent on April 25, 2006 saying the coal pile runoff
needed an NPDES wastewater permit. Was this permit ever obtained? The pile was not put outside.
4. Do you have a waste water permit? No. They have an Industrial User permit with Winton but have not sent water to
them in years. Slag quench water is in a closed system pond. -
5. Do you have onsite vehicle maintenance? Yes, mostly indoors.

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000379
Nucor Steel
Hertford County
Dear Mr. Daughtridge:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
1. Analytical monitoring parameters, pH, COD, TSS, Nitrate -Nitrite, P, Oil & Grease, Antimony, Copper,
Lead, Magnesium, Mercury, Silver, and Zinc, have been maintained in this permit. BOD, TKN, Phenol,.
Arsenic, Barium, Beryllium, Cadmium, Manganese, Selenium, Thallium, Napthlene, TrichloroethyIene,
and Tetrachloroethylene have been removed from the monitoring.
2, All, analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part II Section B. The permittee must also document the total precipitation for each event. If no discharge
occurs during the sampling period, the permittee must submit a monitoring report indicating "No Flow"
within 30 days of the end of the six-month sampling period. Additionally, samples must be taken a
minimum of 60 days apart as specified in Table 2.
3. Benchmarks for analytical monitoring have been added to this draft permit. 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. If the
sampling results are above a benchmark value, or outside of the benchmark range, for any parameter at
any outfall then the facility shall follow the Tier 1 guidelines which require a facility inspection within .
two weeks and implementation of a mitigation plan within two months. If during the term of this permit,
the sampling results are above the benchmark values, or outside of the benchmark range, for any specific
parameter at a specific discharge outfall two times in a row (consecutive), then the facility shall follow the
Tier 2 guidelines which require a repetition of the steps listed for Tier 1 and also immediately institute
monthly monitoring for all parameters at every outfall where a sampling result exceeded the benchmark
value for two consecutive samples.
4. You are required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part U Section B. Qualitative monitoring is required regardless of
representative outfall status.

Mr. Griffin Daughtridge
Nucor Steel
Permit No. NCS000379
5. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.)
7. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical
and qualitative monitoring. This requirement appears in all Individual Stormwater permits, however it
only applies to facilities that do vehicle maintenance. if the facility begins vehicle maintenance during the
permitted timeframe then the requirements shall apply.
Other Rermit changes: -
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants
in each outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of
significant spills that have occurred in the past three years and also must certify that the outfalls have
been inspected to ensure that they do not contain non-Stormwater discharges. Additional information is
provided in Part 11 Section A.
2. -Additional requirements for the Stormwater Management Plan have been specified in Part II Section A.
More details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II
Section A. The plan must also be updated annually to include a list of significant spills and to certify that
the outfalls do not contain non-Stormwater discharges.
4. The facility must now implement a semi-annual Facility. Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft 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 Exclusion from NPDES stormwater discharge permit
requirements. Additional information is provided in Part I Section A.
Please submit any comments to me no later than thirty (30} days following your receipt'of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] or

Special Issues Explanation:
a Nucor planned to store coal in a small uncovered coal pile at the facility (2005). We told the facility
they will need an NPDES permit if they will have coal pile runoff(2006 email Gil Vinzani to Ken Pickle).
Update: The coal pile was not put outside (April 2009). +
Description of Onsite Activities:-
0 Nucor Steel — Hertford County is a steel recycling facility that receives scrap steel, alloys and other raw
material. These materials are stored and then charged to an electric arc furnace (EAF) that melts the steel.
We then tap.the molten steel from the EAF into a ladle, transfer it to a ladle metallurgy furnace (LMF) to
adjust the chemistry then transfer it again to a continuous caster where }we -cast 6" slabs up to 10' wide. The
slabs are then reheated to the proper temperature and hot rolled to produce plate steel 318" to 2" thick. The
Page 1 of 9

NCS000379
' plates are then leveled, sheared and shipped as discrete plate via truck and rail car. Other activities on -site,
include -vehicle maintenance, slag and mill scale processing and other general maintenance and repair.
• The facility is located on 984 acres in the Chowan River Basin. They have constructed four storm
water ponds that drain 517 acres, encompassing the developed portion of the property. The remaining 467
acres are undisturbed areas consisting mostly of woodlands and preserved wetlands. These undisturbed
acres do not drain to the storm water ponds.

Central Office Review Summary:
1. Owner's Other Permits:
• Air — 3709100099, NE12NC100099
• RCRA—NCR000011197
2. General Observations:
3. Impairment: The site is on the 25a2b section of the Chowan River and is not rated for the aquatic life rating.
The Chowan River (25al) is on the 303d list for a Standard violation: low dissolved oxygen and a fish advisory:
Mercury. Possible sources are agriculture and intensive animal feeding operations. The Chowan River 25a2 is
on the 303d list for a fish advisory: Mercury. Possible sources are industrial, municipal and atmospheric
deposition. The Chowan River (25b, 25c) is on the 303(d) list for Historical Listing decision: Nutrients. Chowan
Basinwide Plan recommendation for 2007: DWQ recommends that the upper Chowan River [AU# 25al ] be
removed from the 2008 303(d) list of impaired waters for water, quality standards. Ambient monitoring indicates
that no criteria were exceeded beyond natural conditions. Benthic sampling also shows that the biological
community has improved since the previous assessment period.
4. Threatened and Endangered: Based on the Natural Heritage Virtual Workroom there are no federally threatened
or endangered -species within 2 miles of the facility-.
5. Location: The outfalls are located at a B; NSW and a C; NSCW.
6. Industrial Changes Since Previous Permit: There have been no changes since start-up in 2000. (Based on a letter
December 15, 2004)
On December 15, 2005, Nucor submitted .a letter to Ken Pickle explaining the addition of Coal Pile Storage.
Nucor used to store coal in a covered storage area which precluded precipitation and runoff from contacting the
coal. Nucor is planning to expand the facility's, coal storage capacity, which requires that coal be stored in an
uncovered area approximately sixty feet by eighty feet at the facility. A stormwater ditch was designed with a
check dam prior to discharging into the rest of the facility's stormwater management system in order to reduce
the amount of solids in the discharge. Update: The coal pile was not put outside (April 2009).
Changes in Operation
We have submitted an air permit application (PSD) for a plate heat treating facility that will have an annual
capacity of 120,000 tons. The heat treat line will include a natural gas -fired austenitizirig furnace (36
MMBtu/hr), a natural gas -fired tempering furnace (37 MMBtu/hr), a shot blaster,: two plate cutting bed systems
and a cooling tower (3,000 gallons per minute). As part of the same permitting process, we are seeking an
increase in allowed slag processing from 262,000 tons per year to.360,000 tons per year.
7. Analytical Monitoring Notes: Analytical monitoring included pH, Oil and Grease, BOD, COD, TSS, TKN,
Nitrate plus Nitrite Nitrogen, Total Phosphorus, Lead, Zinc, Barium, Magnesium, Manganese, Beryllium,
Cadmium, Thallium, Copper, Mercury, Selenium, Silver, Phenols, Naphthalene, Trichloroethylene, Antimony,
Arsenic, and Tetrachloroethylene. Sampling was to be done annually for the first 3 years and quarterly during
the fourth year. Eight different samples were taken at each outfall Al and A3. Ten samples were taken at
outfall B I and eight samples were taken at outfall C 1. At each outfall there were a couple values that were
outside the current benchmarks for pH and Copper.
The facility is included in the EPA multi -sector general permit for SIC 3312 under Sector F: Primary Metals.
The monitoring recommendations are total aluminum and total zinc.
Maintain monitoring for pH, COD, TSS, Nitrate -Nitrite, P, Oil&Grease, Antimony, Copper, Lead, Magnesium,
Mercury, Silver, and Zinc. BOD, TKN, Phenol, Arsenic, Barium, Beryllium, Cadmium, Manganese, Selenium,
Thallium, Napthlene, Trichloroethylene, and Tetrachloroethylene have been removed from the monitoring. The
parameters were removed from the monitoring because the reported data were either not detected or less than
Page 4 of 9

NCS000379
10% of the benchmark. Barium and Manganese were removed from the monitoring because the values were
low and there are no current benchmarks created for them.
S. Qualitative Monitoring Notes: Visual monitoring was done from 08/29/02 to.10/27/04 for all four outfalls. A
few entries _had tan colored water. Notes show that a couple times an overflow pipe broke.

'NCS000379
Revised Permit Recommendations: Analytical Monitoring.
1. Maintain monitoring for pH, COD, TSS, Nitrate -Nitrite, P, Oil & Grease, Antimony, Copper, Lead, Magnesium,
Mercury, Silver, and Zinc. BOD, TKN, Phenol, Arsenic, Barium, Beryllium, Cadmium, Manganese, Selenium,
Thallium, Napthlene, Trichloroethylene, and TetrachloroethyIene have been removed from the monitoring.
2. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part Il
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must. submit a monitoring report indicating "No Flow" within 30 days
of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2.
3. Benchmarks for analytical monitoring have been added to this draft permit. 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. If the sampling results are above a
benchmark value, or Outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier I guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
4. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of representative
outfall status.
5. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote I of Tables 1, 4,
and 5.
6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
7. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
Additional guidance is provided about the Site Plan. requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part 11 Section
A
2. Additional requirements for the Stormwater Management Plan have been specified in Part II. Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been -specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify.that the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part ll Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft 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 Exclusion from NPDES stormwater discharge permit requirements. Additional information
is provided in Part I Section A.

Discussions with permittee: Giffin Daughtridge — moved to a different facility, talked with Terry Hairston,
Environmental Manager, 252-356-3700, 4/15/09
1. General description of on site industrial activities? Steel Recycling facility. Use electric arc furnaces and
produce steel plates. Bring iAscrap that is stored outside. 1.6 million tons ofend product were produced last
year.
2. Have there been any changes since the application was filed? No. However, the proposed coal pile was not put in
outside but under roof A heat treat facility is planned that will include two small natural gas furnaces that will be
located under roof.
3. Where is the stormwater from the coal pile going? A letter was sent on April 25, 2006 saying the coal pile runoff
needed an NPDES wastewater permit. Was this permit ever obtained? The pile was not put outside.
4. Do you have a wastewater permit? No. They have an Industrial User permit with Winton but have not sent water to
them in years. Slag quench water is in a closed system pond.
5.. Do you have onsite vehicle maintenance? Yes, mostly indoors.

(e) Certification 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 5. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
2. Stormwater Management Plan_ . The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following: � .
(a) Feasibility Study. A review of the tcchnical'and`economic feasibility of changing
the methods of operations and/or storage practic&.& eliminate or reduce exposure
of materials and processes to stormwater. 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, the stormwater managemeritplan shall document the feasibility of
diverting the stormwater runoff away frbrfi areas of potential contamination.
(b) Secondary Containment<Re`tq'uirements and Records. Secondary containment is
required for: bulk`sforag of liquid materials; storage in any amount of Section
3.13 of Title III of the•Supe rfuid Amendments and Reauthorization Act (SARA)

I'll' -
order to prevent leaks and spills from contaminating stormwater runoff. A table
or summary of all.sucetanks. and stored materials and their associated secondary
containment areas shall be maintained. If the secondary containment devices are .
connected directly 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), and 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 the material stored within the containment area. 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 years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and 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.
Part II Page 4 of 10

inventory of the facility. Facility. personnel (or the team) 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 the 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 programshall;be developed. The program shall list
all stormwater control systems, 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.
Inspection of material handling, areas and regular cleaning schedules of these areas shall
be incorporated into the pr ograrriXTimely compliance with the established schedules for
inspections, maintenance, and Housekeeping shall be recorded in writing and maintained
in the SPPP.
5, 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. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training
shall be documented by the signature of each employee trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of Stormwater
Pollution Prevention Plan shall be reviewed and updated on an annual basis. The annual
update shall include an updated list of significant spills or leaks of pollutants for the
previous three years, or the notation that no spills have occurred. The annual update shall
include re -certification that the stormwater outfalls have been evaluated for the presence
of non-stormwater discharges. Each annual update shall include a re-evaluation of the
Part II Page 5 of 10

effectiveness of the BMPs listed in the BMP Summary of the Stormwater Management Plan. .
The Director may notify the permittee when the Plan 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 Plan to meet minimum
requirements.. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 5) to the Director that the changes
have been made.
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
required in Part H B and C of this permit.
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
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 years and made available to the Director or the Director's authorized representative
immediately upon request.
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 representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted- over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.

bag.
When performing maintenance in a baghouse compartment, any dust found on the floor
shall be swept down a filter bag hole in a cell plate (after removal of a filter of course).

SWPPP -- Best Management Practices
Fueling Stations:
• An automatic shut-off device should be installed on all gasoline and diesel fuel
pumps.
• Install spills and overfill prevention equipment on fuel storage tanks and pumps.
• Avoid "topping off' vehicle fuel tanks.
• Grading, berming or curbing fueling area to avoid storm water run off.
• Store sorbent material near fueling areas to absorb spills.
Sediment and Erosion Prevention
Unpaved yard/operation areas are periodically regraded to prevent the formation of ruts .
and gullies. Gravel and stone aggregate placement at the sites should be coarse, with a
minimum amount of fine particles, which would be easily flushed by runoff.
A good vegetative cover is maintained in non -operational unpaved areas.
Any observed erosion, scouring or sedimentation should 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.
Scrap, Slag, and Mill Scale Storage and Processing Areas
Prevent storm water run off by:
• Storing scrap and slag on more elevated portions of the facility; or
• Constructing curbs, berms, or storm water conveyance ditches around the elevated
or higher portion of the scrap yard or slag storage area.
Construct slag aggregate piles to maintain a steep slope so as to minimize the area
exposed to rainfall.
Install grass or other vegetation buffer strips to promote filtration and remove solids.
Ba house Operations
During loading of baghouse dust to rail car the rail car loader shall sweep up any spilled
EAF dust in the silo area and dispose of as hazardous waste.
Labels and covers shall be kept on the satellite drums at all times.

Nucor Steel — Hertford County
SWPPP — Best Management Practices
Spill Prevention and Response
Any observed leak or spill should 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.
We repair any damaged container prior to outdoor transport.
Whenever possible we collect free liquids using various types of pumps and then use dry
cleanup methods, such as absorbent materials, on all significant leaks and spills. An
adequate supply of absorbent materials is maintained, and used absorbent material shall
be swept up and properly disposed of
An adequate amount of dry absorbent is stored near fuel pumps, tanks, and. other areas
prone to spills, and used as needed to contain and cleanup spills.
Berms and curbing may be constructed to contain areas prone to spills.
Proper compatible storage containers should be used for materials stored outside. Any
damaged containers should be repaired or the materials in the damaged containers
transferred to a new undamaged container. All containers should be clearly labeled.
Drums containing liquids, including oil and lubricants, shall be stored indoors, in a
bermed area; in overpack containers or spill pallets; or in similar containment devices.
Special care should be taken to prevent and immediately clean up any leaks or spills that
occur in recessed loading dock areas that drain to a sump. The sump water should, where
practicable, be discharged to the facility's water treatment plant or sanitary sewer (with
permission).
Absorbent pads and blankets may be placed in, or around, storm drains to collect
sediments and oily substances.
Liquid Storage in Aboveground Tanks:
• Comply with existing spill prevention, cleanup and countermeasures plans
(SPCC) and incorporate by reference.
• Employ engineering safeguards to prevent accidental releases of pollutants.
• Install overflow protection devices on tank systems to warn operator or to
automatically shut down transfer pumps when tank reaches full capacity.
• Place protective guards around tanks and piping to prevent vehicle or forklift
damage.
• Clearly tag or label valves to reduce human error.
• Visually inspect tank system to identify, problem areas.
• Provide secondary containment system around both permanent and temporary
tanks.

Nucor Steel — Hertford County
SWPPP — Best Management Practices
Outside Storage of Raw Materials, By -Products or Finished Products:
• Store all materials indoors to the extent practicable.
• Prevent storm water run off by enclosing area or building a berm around the area.
Preventative Maintenance
Containment berms and aboveground storage tank_ s are inspected monthly for leaks,
cracks, and other signs of deterioration.
Material storage areas are inspected monthly for corroded and damaged drums, boxes,
crates, and bags, or other potential causes of leaks and spills.- Items identified are
repaired or contained, and any spillage immediately cleaned up.
A preventative inspection and testing program has been developed for all major
equipment use or stored outside (including vehicles) that could lead to storm water runoff
contamination. The program includes:
T
• Service checklists and maintenance logs for each piece of equipment.
• Employee education and instruction materials; and
• Review of manufacturer -recommended frequency of parts replacement and
maintenance activities.
Major equipment used or stored outside is kept clean by frequently removing
accumulated oil and grease that may be exposed to storm water or that may hide
equipment trouble spots.
Scheduled maintenance of vehicles and major equipment (except cranes, locomotives and
stationary equipment), shall be conducted in a covered or bermed area.
Storm water management devices (e.g. cleaning oil/water separators, cleaning catch
basins, cleaning sumps) are inspected regularly and properly maintained.
Vehicle and Equipment Maintenance:
• Prevent spills and drips of solvents and cleaners on the shop floor.
• Check for leaking oil and fluids.
• . Use nontoxic or low toxicity materials and solvents when possible.
• Use recycled•or recyclable products when possible.
• Avoid hosing down work areas unless spilled materials are cleaned up first.
• Do not pour liquid waste in floor drains, sinks, or r outdoor storm drains.
• Drain oil filters before disposal or recycling.

General - Good Housekeeping
Store supplies, equipment, and other materials under roof to maximum extent possible.
All drums containing any chemical, oil, fuel, or hazardous waste shall be properly
secured and labeled.
Trash dumpsters on the site will be routinely pulled before the contents spill out. Free
liquid material shall not be placed in these dumpsters.
Toxic and hazardous materials shall be stored inside, if safety provisions allow, or in a
covered area.
The facility is kept clean by regularly picking up trash and litter.
The facility shall use fertilizer, herbicide and pesticides in a judicious manner to prevent
overuse of these materials.
Paved areas are swept on a regular basis during the summer months. Dust control such as
water and asphaltic emulsion shall be applied to unpaved travel roads as needed.
Pollution prevention concepts shall be regularly publicized to employees.
Painting Operations:
• Inspect and properly prepare parts for painting.
• Contain and properly dispose of or reuse sanding and sandblasting materials
where possible.
• Prevent paint waste from contacting stormwater.
• Properly store paint and solvents under cover.
• Make sure paint equipment is operating efficiently and does not leak.
• Recycle paint, paint thinner, and solvents whenever possible and dispose of
properly when recycling is not feasible.
Vehicle and Equipment Washing:
Oily equipment and vehicles are to be washed or steam cleaned inside contained
areas only.
Use phosphate free biodegradable detergents.
Loading and Unloading Materials:
• Loading areas should be swept on a regular basis.
• Grade berm or curb area around loading area to prevent storm water runoff
contamination.
• Inspect trucks for leaks.
Clean loading areas of accidental spills immediately

Permit No. NCS000379
PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan 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 water(s) to which the
stormwater outfall(s) discharges, 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 point(s) of discharge.
(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.
(c) A site map drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials, disposal areas, process areas
and loading and unloading areas), drainage structures, drainage areas for each
outfall and activities occurring in the drainage area, building locations, existing
BMPs and impervious surfaces, and the percentage of each drainage area that is
impervious. For each outfall, a narrative description of the potential pollutants
which could be expected to be present in the stormwater discharge.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
(e) Certification 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 Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
Part 11 Page t of 8

Permit No. NCS000379
(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 stormwater. 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, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous substances to prevent leaks and spills from
contaminating stormwater runoff. If the secondary containment devices are
connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be
secured with a locking mechanism] and 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 the material stored within the containment area. 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 years.
(c) BMP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be
based on the assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, a SPCC plan 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 program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.
Part II Page 2 of 8

Permit No. NCS000379
5. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel
(or team) responsible for implementing the training shall be identified.
6. Responsible Party, The Stormwater Pollution Prevention PIan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
The Director may notify the permittee when the Plan 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 Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part 1I1, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
8. Facility Inspection Program. Facilities are required to inspect all stormwater systems on
at least a semiannual schedule, once in the fall (September -November) and once in the
spring (April - June). The inspection and any subsequent maintenance activities
performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control
systems, plant equipment and systems. Records of these inspections shall be
incorporated into the Stormwater Pollution Prevention Plan.
Stormwater discharge characteristic monitoring as required in Part II of this permit shall
be performed in addition to facility inspections.
9. Implementation. The permittee shall document all monitoring, measurements,
inspections and maintenance activities and training provided to employees, including the
log of the sampling data and of activities 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 years and made available to the Director or his
authorized representative immediately upon request.

year of the permit term. A year is defined as the 12 month period beginning on the month and day of issuance of
the Permit. See Table 2 for schedule of monitoring periods.
2 If the stormwater runoff is controlled by a stormwater detention pond, a grab sample of the discharge from the
pond shall be collected within the first 30 minutes of discharge. If the detention pond discharges only in response
to a storm event exceeding a ten year design storm, then no analytical monitoring is required and only qualitative
monitoring shall be performed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless representative
outfall status has been granted,
4 For each sampled representative storm event the total precipitation, storm duration, and total flow must be
monitored. Total flow shall be either; (a) measured continuously, (b) calculated based on the amount of area
draining to the outfall, the amount of built -upon (impervious) area, and the total amount of rainfall, or (c)
estimated by the measurement of Flow at 20 minute intervals during the rainfall event.

representative outfall status and shall be performed as specified below in Table 3. Qualitative
monitoring is for the purpose of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assessing new sources of stormwater pollution. No analytical tests
are required. Qualitative monitoring of stormwater outfalls does not need to be performed during
a representative storm event.
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 Stormwater Pollution Prevention
Plan.
All qualitative monitoring will be performed twice per year, once in the spring (April - June) and
once in the fall (September - November).

Special Issues Explanation: ,
• Nucor planned, to store coal in a small uncovered coal pile at the facility (2005). We told the facility
they will need an NPDES permit if they will have coal pile runoff (2006 email Gil Vinzani to Ken Pickle).
Update: The coal pile was not put outside (April 2009).
Description of Onsite Activities:
• Nucor Steel — Hertford County is a steel recycling facility that receives scrap steel, alloys and other raw
material. These materials are stored and then charged to an electric are furnace (EAF) that melts the steel.
We then tapthe molten steel from the EAF into a ladle, transfer it to a ladle metallurgy furnace (LMF) to
adjust the chemistry then transfer it again to a continuous caster where we cast 6" slabs up to 10' wide. The
slabs are then reheated to the proper temperature and hot rolled to produce plate steel 3/8" to 2" thick. The
Page 1 of 9

r
NCS000379
plates are then leveled, sheared and shipped as discrete plate via truck and rail car. Other activities on -site,
include vehicle maintenance, slag and mill scale processing and other general maintenance and repair.
• The facility is located on 984 acres in the Chowan River Basin. They have constructed four storm
water ponds that drain 517 acres, encompassing the developed portion of the property. The remaining 467
acres are undisturbed areas consisting mostly of woodlands and preserved wetlands. These undisturbed
acres do not drain to the storm water'ponds.

Central Office Review Summary:
1. Owner's Other Permits:
+ Air — 3709100099, NE12NCI00099
• RCRA — NCROOOO 11197
2. General Observations:
3. Impairment: The site is on the 25a2b section of the Chowan River and is not rated for the aquatic life rating.
The Chowan River (25al) is on the 303d list for a Standard violation: low dissolved oxygen and a fish advisory:
Mercury. Possible sources are agriculture and intensive animal feeding operations. The Chowan River 25a2 is
on the 303d list for a fish advisory: Mercury. Possible sources are industrial, municipal and atmospheric
deposition. The Chowan River (25b, 25c) is on the 303(d) list for Historical Listing decision: Nutrients. Chowan
Basinwide Plan recommendation for 2007: DWQ recommends that the upper Chowan River [AU# 25al ] be
removed from the 2008 303(d) list of impaired waters for water quality standards. Ambient monitoring indicates
that no criteria were exceeded beyond natural conditions. Benthic sampling also shows that the biological
community has improved since the previous assessment period.
4. Threatened and Endan erect: Based on the Natural Heritage Virtual Workroom there are no federally threatened
or endangered species within 2 miles of the facility...
5. Location: The outfalls are located at a B; NSW and a C; NSCW.
6. Industrial Changes Since Previous Permit: There have been no changes since start-up in 2000. (Based on a letter
December 15, 2004)
On December 15, 2005, Nucor submitted.a letter to Ken Pickle explaining the addition of Coal Pile Storage.
Nucor used to store coal in a covered storage area which precluded precipitation and runoff from contacting the
coal. Nucor is planning to expand the facility's coal storage capacity, which requires that coal be stored in an
uncovered area approximately sixty feet by eighty feet at the facility. A stormwater ditch was designed with a
check dam prior to discharging into the rest of the facility's stormwater management system in order to reduce
the amount of solids in the discharge. Update: The coal pile was not put outside (April 2009).
Chany,es in Operation
We have submitted an air permit application (PSD) for a plate heat treating facility that will have an annual
capacity of 120,000 tons. The heat treat line will include a natural gas -tired ;austenitizing furnace (36
MMBtulhr), a natural gas -fired tempering furnace (37 MMBtulhr), a shot blaster, two plate cutting bed systems
and a cooling tower (3,000 gallons per minute). As partof the same permitting process, we are seeking an
increase in allowed slag processing from 262,000 tons per year to.360,000 tons per year.
7. Analytical Monitoring Notes: Analytical monitoring included pH, Oil and Grease, BOD, COD, TSS, TKN,
Nitrate plus Nitrite Nitrogen, Total Phosphorus, Lead, Zinc, Barium, Magnesium, Manganese, Beryllium,
Cadmium, Thallium, Copper, Mercury, Selenium, Silver, Phenols, Naphthalene, Trichloroethylene, Antimony,
Arsenic, and Tetrachloroethylene. Sampling was to be done annually for the first 3 years and quarterly during
the fourth year. Eight different samples were taken at each outfall Al and A3. Ten samples were taken at
outfall BI and eight samples were taken at outfall Cl. At each outfall there were a couple values that were
outside the current benchmarks for pH and Copper.
The facility is included in the EPA multi -sector general permit for SIC 3312 under Sector F: Primary Metals.
The monitoring recommendations are total aluminum and total zinc.
Maintain monitoring for pli, COD, TSS, Nitrate -Nitrite, P, Oil&Grease, Antimony, Copper, Lead, Magnesium,
Mercury, Silver, and Zinc. BOD, TKN, Phenol, Arsenic, Barium, Beryllium, Cadmium, Manganese, Selenium,
Thallium, Napthlene, Trichloroethylene, and Tetrachloroethylene have been removed from the monitoring. The
parameters were removed from the monitoring because the reported data were either not detected or less than
Page 4 of 9

NCS000379
10% of the benchmark. Barium and Manganese were removed from the monitoring because the values were
low and there are no current benchmarks, created for them.
8. Qualitative Monitoring Notes. Visual monitoring was done from 08/29/02 to.10/27/04 for all four outfails. A
few entries had tan colored water. Notes show that a couple times an overflow pipe broke.

Revised Permit Recommendations: Analytical Monitoring:
1. ain—t`ditt'monitoring-for'p%i; COD—TSSWNitrate-1 il:rite P`Oi1:8 Grease—A�}timor Lopper;�ead,�IYJagnes um,
ercurY� ilver,—any inc. BOD, TKN, Phenol, Arsenic, Barium, BerJllium, admiu ,Manganese, Selenium,
Thallium Napthlene Trichloroethylene, and etrachloroethylene have been removed from the monitoring.
2. All analytical itorin has been sett semi-annua during a representative storm event as defined in Part lI
ection ie permi ee must also docume al precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30 days
of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2.
3. enchmarks for anal ical monitoring have been added to t is raft perms . Exceedam es of benchmark values
require the permittee to increase monitoring, increase managerneritacLions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs) in a iered progra4 If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier I guidelines which require a facility inspection within two weeks and implementation of
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific pararietdr at a specific discharge outfall
two times in.a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples. .
4. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part 1I Section B. Qualitative monitoring is required regardless of representative
outfall status.
5. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
6. The flow reporting requirement has been removed per DWQ revised strategy. {The total "rainfall parameter is in
this permitloowever.)
7. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
I . Additional guidance is provided about the Site Plan.requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that, they do not contain non-stormwater discharges. Additional information is provided in Part 11 Section
A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II. Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify .that. the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a serni-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part 11 Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft 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 Exclusion from NPDES stormwater discharge permit requirements. Additional information
is provided in Part I Section A.

produce steel plates. Bring *scrap that is stored outside. 1.6 million tons of end product were produced last
Year.
2. Have there been any changes since the application was filed? No. However, the proposed coal pile was not put in
outside but under roof. A heat treat facility is planned that will include two small natural gas furnaces that will be
located under roof.
3. Where is the stormwater from the coal pile going? A letter was sent on April 25, 2006 saying the coal pile runoff
needed an NPDES wastewater permit. Was this permit ever obtained? The pile was not put outside."
4. Do you have a waste water permit? No. They have an Industrial User permit with Winton but have not sent water to
them in years. Slag quench water is in a closed system pond. (-O— ,�

SECTION B: ANALYTICAL- MONITORING REQUIREMENTS

0
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted- over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example,.if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.

water quality assessment that provides the scientific foundation for an implementation plan. The
implementation plan outlines the steps necessary to reduce pollutant loads in a certain body of water to
restore and maintain water quality standards in all seasons. TheOC.lean Water Act, Section 303, establishes
the water quality standards and TMDL programs. U P
33. Toxic Pollutant

Nucor Steel -- Hertford County
SWPPP -- Best Management Practices
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.
When changing filter bags in the baghouse, place filters inside a plastic bag and seal the
bag.
When performing maintenance in a baghouse compartment, any dust found on the floor
shall be swept down a filter bag hole in a cell plate (after removal of a filter of course).

Nucor Steel — Hertford County
SWPPP — Best Management Practices
Fueling Stations:
• An automatic shut-off device should be installed on all gasoline and diesel fuel
pumps.
• Install spills and overfill prevention equipment on fuel storage tanks and pumps.
• Avoid "topping off"vehicle vehicle fuel tanks.
• Grading, berming or curbing fueling area to avoid storm water run off.
• Store sorbent material near fueling areas to absorb spills.
Sediment and Erosion Prevention
Unpaved yard/operation areas are periodically regraded to prevent the formation of ruts
and gullies. Gravel and stone aggregate placement at the sites should be coarse, with a
minimum amount of fine particles, which would be easily flushed by runoff.
A good vegetative cover is maintained in non -operational unpaved areas.
Any observed erosion, scouring or sedimentation should be controlled using appropriate
vegetative, stabilization, or structural measures.
Vegetative filter strips maybe installed to provide a buffer area around the facility
operation areas.
Grassed swales may be used to stabilize eroded ditches or channels.
Scrap, Slay, and Mill Scale Storage and Processine Areas
Prevent storm water run off by:
• Storing scrap and slag on more elevated portions of the facility; or
• Constructing curbs, berms, or storm water conveyance ditches around the elevated
or higher portion of the scrap yard or slag storage area.
Construct slag aggregate piles to maintain a steep slope so as to minimize the area
exposed to rainfall.
Install grass or other vegetation buffer strips to promote filtration and remove solids.
Baghouse Operations
During loading of baghouse dust to rail car the rail car loader shall sweep up any spilled
EAF dust in the silo area and dispose of as hazardous waste.
Labels and covers shall be kept on the satellite drums at all times.

Nucor Steel — Hertford County
SWPPP — Best Management Practices
Spill Prevention and Response
Any observed leak or spill should 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.
We repair any damaged container prior to outdoor transport.
Whenever possible we collect free liquids using various types of pumps and then use dry
cleanup methods, such as absorbent materials, on all significant leaks and spills. An
adequate supply of absorbent materials is maintained, and used absorbent material shall
be swept up and properly disposed of.
An adequate amount of dry absorbent is stored near file] pumps, tanks, and other areas
prone to spills, and used as needed to contain and cleanup spills.
Berms and curbing may be constructed to contain areas prone to spills.
Proper compatible storage containers should be used for materials stored outside. Any
damaged containers should be repaired or the materials in the damaged containers
transferred to a new undamaged container. All containers should be clearly labeled.
Drums containing liquids, including oil and lubricants, shall be stored indoors, in a
bermed area; in overpack containers or spill pallets; or in similar containment devices.
Special care should be taken to prevent and immediately clean up any leaks or spills that
occur in recessed loading dock areas that drain to a sump. The sump water should, where
practicable, be discharged to the facility's water treatment plant or sanitary sewer (with
permission). '
Absorbent pads and blankets may be placed in, or around, storm drains to collect
sediments and oily substances.
Liquid Storage in Aboveground Tanks:
• Comply with existing spill prevention, cleanup and countermeasures plans
(SPCC) and incorporate by reference.
• Employ engineering safeguards to prevent accidental releases of pollutants.
• Install overflow protection devices on tank systems to warn operator or to
automatically shut down transfer pumps when tank reaches full capacity.
• Place protective guards around tanks and piping to prevent vehicle or forklift
damage.
! Clearly tag or label valves to reduce human error.
• Visually inspect tank system to identify problem areas.
• Provide secondary containment system around both permanent and temporary
tanks.

Nudor Steel — Hertford County
SWPPP -- Best Management Practices
Outside Storage of Raw Materials, By -Products or Finished Products:
• Store all materials indoors to the extent practicable.
• Prevent storm water run off by enclosing area or building a berm around the area.
Preventative Maintenance
Containment berms and aboveground storage tanks are inspected monthly for leaks,
cracks, and other signs of deterioration.
Material storage areas are inspected monthly for corroded and damaged drums, boxes,
crates, and bags, or other potential causes of leaks and spills.. Items identified are
repaired or contained, and any spillage immediately cleaned up.
A preventative inspection and testing program has been developed for all major
equipment use or stored outside (including vehicles) that could lead to storm water runoff
contamination. The program includes:
• Service checklists and maintenance logs for each piece of equipment.
• Employee education and instruction materials; and
• Review of manufacturer -recommended frequency of parts replacement and
maintenance activities.
Major equipment used or stored outside is kept clean by frequently removing
accumulated oil and grease that may be exposed to storm water or that may hide
equipment trouble spots.
Scheduled maintenance of vehicles and major equipment (except cranes, locomotives and
stationary equipment), shall be conducted in a covered or bermed area.
Storm water management devices (e.g. cleaning oil/water separators, cleaning catch
basins, cleaning sumps) are inspected regularly and properly maintained.
Vehicle and Equipment Maintenance:
• Prevent spills and drips of solvents and cleaners on the shop floor.
• Check for leaking oil and fluids.
• . Use nontoxic or low toxicity materials and solvents when possible.
• Use recycled or recyclable products when possible.
• Avoid hosing down work areas unless spilled materials are cleaned up first.
• Do not pour liquid waste in floor drains, sinks, or outdoor storm drains.
• Drain oil filters before disposal or recycling.
