NC Division of Energy, Mineral and Land Resources
Review for Permit Renewal — NCS000304
Gerdau Ameristeel US, Inc.
Charlotte, NC
Facility Activities and Process - SIC 3312 —Steel Manufacturing.
Monitoring —The facility has been monitoring for TSS, BOD, COD, Al, Cd, Cr, Cu, Pb, Ni, Zn, 0&G, and pH. Previous
permit did have tier system.
Data from 2009 — 2013 (in renewal app)
Al, Cu, Pb, Zn and TSS had values consistently above the benchmark numbers through this time period. The
metals results were compared to current benchmark values and not the lower ones that were in the
previous permit.
Cd, BOO and pH has more sporadic benchmark exceedances over the time period.
COD had consistent exceedances up until the middle of 2012.
Cr, Ni and O&G had few or no exceedances over the time period.
2014-present — only a few DMRs submitted? 2014 —1, 2015 —1, 2016 — 0, 2017 — 3. Facility staff are fairly
new and not aware of some past activities but felt that the few DMRs was a result of no discharge from the
facility. Data from this time period show numbers near or over benchmarks only for Cu, Zn and Cd.
Propose removing Cr, Ni, O&G and BOO.
Maintain in permit -> TSS, COD, Al, Cd, Cu, Pb, Zn and pH.
Tier structure adjusted to have the three levels as in current permits.
— Parameter codes added to permit.
Discussions with Facility — Need to check on changes in 2012 that may have resulted in the monitoring result
changes. Check on the ponds onsite and sample locations. Why are they only monitoring outfall 002? Conference
call 9/5/2018 with Bob Churchill, Jill Gee and Kristina Brink (consultant). See second page of this document with
summary email after call. Jill responded 9/14/18 and 9/17/18 through email and with documents. Information is
included in the file and in the Laserfiche folder. Main items from this information.
Facility collects a lot of onsite stormwater for use in their process. They have three onsite ponds and flow
goes through these (pumped, etc.) ultimately to the North pond to be used in their process. No process
water is mixed in the stormwater ponds so any overflow and discharge is stormwater. Exception is the west
pond that collects some slag cooling water and is treated with CO2 as needed. This has been permitted for
some time in the stormwater system and seems okay.
Nomenclature for outfalls and ponds is similar but these aren't really the same. Review the Outfall
Narrative document for clarification.
Discharges are only in larger events as overflow from areas where stormwater is collected for use in
process.
They do not feel that there is any discharge of landfill leachate as questioned in the 2013 inspection.
Oil -Water Separator on site is no longer utilized and may be removed.
— The facility wants to continue to monitor Outfall 4 as their only representative outfall. After clarification in
the outfall narrative it appears that this outfall does handle the major flow across the site and should be
okay as representative outfall. This should be evaluated at the site visit.
— The documents provided — Outfall Narrative, Water Systems Map and Topographic Map are helpful in
understanding the stormwater characteristics at the site.
Surface Water Information - Facility drains to UT to Long Creek Creek in the Catawba River Basin, 11-120-(0.5) , a
class C stream. 2016 Integrated Report does not list this stream segment specifically as having any impairment
issues. There are some parameters noted (Cu, Fe, TSS and Turbidity) as being in Category 3 indicating data is
inconclusive. There is a 2005 TMDL that was developed for various streams in the Catawba basin including Long
Creek. This facility has had some TSS values that exceeded the benchmark, though not in the most recent
monitoring.
NC National Heritage review — NHP report shows no aquatic resources within project area. Within one mile there
are some managed areas like open space. But no areas of concern for the discharge from this facility.
Regional Office Information - MRO — Draft to region and CMSWS on 9/19/2018 by email. MRO inspected 10/17/18
and emailed approval to issue 10/22/18. Talked to James 11/5/18 about sample locations and possible dry weather
flow issues. He seemed ok with sample point but had encouraged them to sample upstream of the 004 location
closer to industrial activity. James want to go out in drier weather to evaluate the possible dry weather flow.

Stormwater Permit Renewal Information —

Text of email sent after call 9116118) and documents provided in
Date: September 6, 2018, 8:46 PM answering these items [Email from Jill
To: [e-mail]; [e-mail] 9-17-181. Copy in file and in Laserfiche
folder.
Bob, Jill,
Thanks for taking the time yesterday for the conference call to discuss this permit renewal. The talk was helpful in the
process. As I indicated I am sending this email to hopefully touch on the points we discussed and highlight (underlined) the
areas where you were going to try and provide additional information.
• Contact updates —you indicated that there where a number of changes that need to be made from the report that I
forwarded previously. Please send me the needed changes and we will set them updated in our database.
• Electronic reporting — EPA regulation do now require electronic reporting of data and some other reports. At this point
our database is not yet ready to support electronic entry of stormwater DMR data. This will happen during the permit
cycle so the language will be in the permit, but at first you will continue to submit DMR data in hard copy form. When
electronic submittal is ready all permitees will be notified. We do still need to gather accurate latitude/longitude for
outfall points.
• Outfalls - We discussed the outfalls at the facility. It was noted that the facility is set up to capture stormwater and reuse
stormwater in the production process. Actual "process water" is handled in a non -discharge closed loop recycle system
that does not over flow to the stormwater ponds. This system is covered by a DWR Recycle System permit
(WQ0006060).
o Outfall listed as 1 in the application material has previously been noted as draining only employee parking area with
no other "industrial area" drainage going through it. As long as this remains the case then this area is not covered by
the stormwater NPDES permit.
o Outfall 2 - From discussions it appears that with some changes to relocate an entrance this outfall may have been
routed (pumped?) to the South pond. The South Pond is pumped to the North Pond. The South Pond may discharge
in some larger storm events. It appears that this outfall should remain in the permit since the discharge would occur
for events smaller than the 25 yr storm event. '
o Outfall 3 — North Pond. This pond is used as make up water for your process and feeds various holding ponds. No
process water is returned to the pond. Outfall location for monitoring should be at the outlet of the North Pond.
Given the use of water in your process this pond will only discharge for larger events like the South Pond.
o Outfall 4 — West Pond. Water from the West Pond is pumped to the South Pond, so it ultimately goes to the North
Pond. West pond receives stormwater flow but also some slag cooling water. Appears that this water is pH adjusted
with lime. The water is diluted through the three -pond system and this was addressed in the previous issuance of
the permit.
Please verify this information and provide narrative information and possibly site drainage info to verify to confirm the
characterization of the outfalls. In our discussions we noted that there are some questions aboutyouroutfalls that
would be best addressed as part of the site visit with our regional office staff.
• Monitoring —As I noted in our call, we have a summary of your monitoring data for 2010-2013 as part of your renewal
application submitted in 2013. Our records show only a few DMR submittals since that time. Can you please provide a
summary of your available data from 2014-the resent?
• You asked about monitoring schedule and if this could be placed on an annual cycle. All of our current permits are set up
this way and your renewed permit will required semi-annual monitoring with the first sampling period January -June and
the second July- December.
• In a 2013 inspection report to your facility it was noted that inspection staff had observed dry weather flow that
potentially came from your capped landfill. The report asked for a response on this issue, but we don't have any record
of a response. In our call youindicated that you had a copy of this report and would review the findings and provide a
response on this issue_
• Oil -Water Separator— It appears that the O/W Separator is no longer in place.
• It doesn't appear that there have been any major operational, process or site changes since the renewal application that
would impact the potential sources of stormwater pollution.
• If there is an updated site map that would help with characterizing drainage areas and outfalls, an electronic copy would
be helpful.

Thanks for the info James. It looks like you have communicated directly with them and they are going to email you the
results. Could you forward the results to us when you get them. Also, do you feel that these four outfalls will be the
ones they should be monitoring? If so, we will need to get locations for the outfalls (lat/Long) so we can update the
outfalls in RIMS.

Subject: Four Permit Renewals in Mecklenburg County
Hey Guys,
I have four more Mecklenburg County stormwater permit renewals heading to public notice. These will all appear in a
public notice in the Charlotte Observer on Friday Sept 21st and the comment period will run through October
21". Please take a took at the draft permits at the Laserfiche links below and let us know if you have any

questions/concerns. It would be helpful if you could schedule a site visit for each facility and check these out if possible
over the next 30 days. The Laserfiche links have the draft permit and cover letter and other information that is part of
the renewal file. Let me know if you need any other information or have any problems accessing the files. Below for
each I have included some areas for review.
NCS000040 — Charlotte Pipe and Foundry Co. —1335 S. Clarkson St.
https://edocs.deg.nc.gov/Stormwater/Browse,aspx?id=720757&dbid=0&repo=WaterResou rces
This facility probably needs some review of their outfall locations. They have some areas where they have questions
since at least one outfall (005A) doesn't get much flow. The facility continues to have some issues with some metals
(Cu, Pb and Zn remain in the permit).
NCS000049 — IMG Resins USA, Inc. — 3300 Westinghouse Blvd.
https://edocs.deq.nc.gov/StormwaterZBrowse,aspx?id=720887&dbid=0&repo=WaterResou rces
One big issue with this facility relates again to outfalls. Back in 2010 there was an inspection that found that a perimeter
swale around the facility may instead be a stream segment. They had been monitoring the swale. We asked them to
instead monitor an outfall to the swale. After talking with them I think this really needs to be worked out at the
site. The correspondence from before is in the Laserfiche folder.
NC5000304 — Gerdau Ameristeel US, Inc. — 6601 Lakeview Rd.
https://edocs.dec[.nc.gov/Stormwater/Browse.aspx?id=706112&dbid=0&repo=WaterResources
This facility has a number of ponds onsite and they capture and use a lot of stormwater in their industrial process. The
ponds are pumped from on to another until it gets to the North pond which feeds into their industrial process use. They
also have a closed loop wastewater recycle system. Process water apparently doesn't comingle with the stormwater but
probably a good idea to check that. The stormwater outfalls appear to only discharge when there are larger storms that
lead to overflow from the ponds (they indicated 2yr storm or more). They want to continue monitoring one outfall (4)
as representative. Probably worth reviewing this to make sure it is okay. Look at the review material in the files along
with the documents they provided. They describe their stormwater flow pretty well and give some maps that help
also. There was an issue in a 2013 inspection about potential dry weather flow from their landfill and they never
responded to the regional office's request to provide info on this. The current staff have indicated that they feel that all
of the leachate is properly collected and the flow was from surface runoff that takes a while to work its way to the
outfall. Probably worth check on this also.
NCS000315 — Nexeo Solutions, LLC — 3930 Glenwood Rd
htt s: edocs.de .nc. ov Stormwater Browse.as x?id=721118&dbid=0&re o=WaterResources
Take a look at the review document in the Laserfiche folder. There were some questions we asked that we haven't
heard back on yet. Related to two outfalls that were removed from the most recent site plan and getting more
information on the containment pond onsite and how it functions, when it discharges, etc.
Sorry for the long email. Hope it is some help. Let me know if you have any questions. My time here as a temp is
winding down. I should be here through a good bit if not all of October, so hopefully we can get these moving toward
issuance before then.
Thanks!

Permit No. NCS000304
Gerdau Ameristeel US, Inc.
Mecklenburg County
Dear Mr. Churchill:
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 I1, 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 I1, Section A.
3. Monitoring requirements in the draft permit have changed slightly from the previous permit.
Monitoring is proposed for Total Suspended Solids (TSS), Chemical Oxygen Demand (COD), Total
Zinc (Zn), Total Aluminum (Al), Cadmium (Cd), Total Copper (Cu), Total Lead (Pb), Total Zinc (Zn)
and pH. Monitoring reported in your renewal application and additional information showed
results for Chromium (Cr), Nickle (Ni), Biological Oxygen Demand (BOD) and Oil and Grease (0&G)
below the benchmark level over the last five years. The draft permit proposes to remove these
parameters from the permit. Comments from our regional staff or other information may result in
maintaining these parameters or adding other parameters if it is apparent that your activities in
some way have the potential to release them at levels of concern through stormwater runoff.
Stormwater benchmarks remain in the permit as before. Keep in mind that 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. The draft permit has modified the tiered response process for benchmark
exceedances consistent with other permits in our program. Please become familiar with the tiered
process as proper response under the tiers may be enforceable items under your permit. Response
to the tiered process may include review of onsite conditions, installation of BMPs or requirements
for more frequent monitoring.

4. Vehicle maintenance (Tables 4 & 5) monitoring parameters have been revised. Non -Polar Oil &
Grease [EPA Method 1664 (SGT-HEM)] replaces Oil & Grease/TPH. The benchmark for Non -polar
Oil & Grease using this method is 15 mg/L. 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. Also,
pH monitoring is no longer required for discharges only associated with vehicle maintenance
activities.
The vehicle maintenance language in the permit has also been modified to clarify that these
activities include not just vehicles, but also other similar equipment maintenance activities that
may be exposed to stormwater. This has always been the Division's implementation of this
requirement, but hopefully the adjusted language is a little clearer about this process.
5. Language has been added under Part I1 Section D to address potential responses to qualitative
. monitoring issues.
6. A new section on Special Conditions has been added in Part 11, Section E to comply with federal
regulations requiring electronic submittal of discharge monitoring reports. Our electronic
submittal process is not available for use at this time, but we will continue to provide feedback on
when this process will be available.
7. Civil and administrative penalty amounts have been updated to reflect current federal law in
Part III, Section A, 2 (b) and (g).
8. The definition of Bulk Storage of Liquid Materials was revised in Part IV Definitions to omit the
language "located in close proximity to each other" as it applies to multiple above ground storage
containers having a combined storage of 1,320 gallons.
9. To address workload issues in the Stormwater Program we are working to have similar numbers of
individual permits for renewal over each of the next five years. In order to accomplish this some of
our permit renewals will be issued for time periods shorter than the usual five year cycle. Your
permit renewal is proposed to expire in 2 02 1.
Please review the draft permit and submit any comments to me no later than 30 days following your
receipt of the draft. Comments maybe emailed tome at bradley.bennett@ncdenr,gov or mailed to my
attention at NC DEMLR, Stormwater Permitting Program, 1612 Mail Service Center, Raleigh, NC 27699-
1612. With this notification the Division will solicit comment on this draft by publishing a notice in a local
newspaper. Following the 30 day public comment period, the Division will review comments and take
appropriate action prior to issuance of the final permit.
If you have any questions, please email me or call me at [phone].

PART I INTRODUCTION
SECTION A: INDIVIDUAL PERMIT COVERAGE
During the period beginning on the effective date of the permit and lasting until expiration,
the permittee is authorized to discharge stormwater associated with industrial activity.
Such discharges shall be controlled, limited and monitored as specified in this permit.
If industrial materials and activities are not exposed to precipitation or runoff as described
in 40 CFR §122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES
stormwater discharge permit requirements. Any owner or operator wishing to obtain a No
Exposure Exclusion must submit a No Exposure Certification Notice of intent (N01) form to
the Division; must receive approval by the Division; must maintain no exposure conditions
unless authorized to discharge under a valid NPDES stormwater permit; and must recertify
the No Exposure Exclusion annually.
SECTION B: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater to the surface waters of North Carolina or separate storm sewer system that
has been adequately treated and managed in accordance with the terms and conditions of
this permit. All stormwater discharges shall be in accordance with the conditions of this
permit.
Any other point source discharge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization, or
approval. The stormwater discharges allowed by this permit shall not cause or contribute
to violations of Water Quality Standards.
This permit does not relieve the permittee from responsibility for compliance with any
other applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or
decree.

Permit No. NCS000304 DRAFT
PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and implement a Stormwater Pollution Prevention Plan
(SPPP). The SPPP shall be maintained on site unless exempted from this requirement by
the Division. The SPPP is public information in accordance with Part III, Standard
Conditions, Section E, paragraph 3 of this permit. The SPPP shall include, at a minimum,
the following items:
1. Site Overview. The Site Overview shall provide a description of the physical facility
and the potential pollutant sources that may be expected to contribute to
contamination of stormwater discharges. The Site Overview shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters; the name of the receiving waters to which the stormwater outfalls
discharge, or if the discharge is to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the points of stormwater discharge associated with industrial
activity. The general location map (or alternatively the site map) shall identify
whether any receiving waters are impaired (on the state's 303 (d) list of impaired
waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants that
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary;
the stormwater discharge outfalls; all on -site and adjacent surface waters and
wetlands; industrial activity areas (including storage of materials, disposal areas,
process areas, loading and unloading areas, and haul roads); site topography and
finished grade; all drainage features and structures; drainage area boundaries and
total contributing area for each outfall; direction of flow in each drainage area;
industrial activities occurring in each drainage area; buildings; stormwater Best
Management Practices (BMPs); and impervious surfaces. The site map must
indicate the percentage of each drainage area that is impervious, and the site map
must include a graphic scale indication and north arrow.
(d) A list of significant spills or leaks of pollutants during the previous three (3) years
and any corrective actions taken to mitigate spill impacts.

Permit No. NCS000304 DRAFT
(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.
Z. Stormwater Management Strategy. The Stormwater Management Strategy shall
contain a narrative description of the materials management practices employed which
control or minimize the stormwater exposure of significant materials, including
structural and nonstructural measures. The Stormwater Management Strategy, at a
minimum, shall incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to rainfall and run-on flows. Wherever practical, the
permittee shall prevent exposure of all storage areas, material handling operations,
and manufacturing or fueling operations. In areas where elimination of exposure is
not practical, this review shall document the feasibility of diverting the stormwater
run-on away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section 313
of Title III of the Superfund Amendments and Reauthorization Act (SARA) water
priority chemicals; and storage in any amount Qfhazardous substances, in order to
prevent leaks and spills from contaminating stormwater runoff. A table or summary
of all such tanks and stored materials and their associated secondary containment
areas shall be maintained. If the secondary containment devices are connected to
stormwater conveyance systems, the connection shall be controlled by manually
activated valves or other similar devices (which shall be secured closed with a
locking mechanism). Any stormwater that accumulates in the containment area
shall be at a minimum visually observed for color, foam, outfall staining, visible
sheens and dry weather flow, prior to release of the accumulated stormwater.
Accumulated stormwater shall be released if found to be uncontaminated by any
material. Records documenting the individual making the observation, the
description of the accumulated stormwater, and the date and time of the release
shall be kept for a period of five (5) years. For facilities subject to a federal oil Spill
Prevention, Control, and Countermeasure Plan (SPCC), any portion of the SPCC Plan
fully compliant with the requirements of this permit may be used to demonstrate
compliance with this permit. The Division may allow exceptions to secondary
containment requirements for mobile refuelers, as with the exemption provided by
amendments to federal SPCC regulations, as long as appropriate spill containment
and/or diversionary structures or equipment is used to prevent discharge to surface
waters. Exceptions do not apply to refuelers or other mobile tankage used primarily
as bulk liquid material storage in a fixed location in place of stationary containers.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs
4

Permit No. NCS000304 DRAFT
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and on data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Procedures. The Spill Prevention and Response
Procedures (SPRP) shall incorporate an assessment of potential pollutant sources based
on a materials inventory of the facility. Facility personnel responsible for implementing
the SPRP shall be identified in a written list incorporated into the SPRP and signed and
dated by each individual acknowledging their responsibilities for the plan. A
responsible person shall be on -site at all times during facility operations that have
increased potential to contaminate stormwater runoff through spills or exposure of
materials associated with the facility operations. The SPRP must be site stormwater
specific. Therefore, an oil Spill Prevention Control and Countermeasure plan (SPCC)
may be a component of the SPRP, but may not be sufficient to completely address the
stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may
be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed and implemented.
The program shall address all stormwater control systems (if applicable), stormwater
discharge outfalls, all on -site and adjacent surface waters and wetlands, industrial
activity areas (including material storage areas, material handling areas, disposal areas,
process areas, loading and unloading areas, and haul roads), all drainage features and
structures, and existing structural BMPs. The program shall establish schedules of
inspections, maintenance, and housekeeping activities of stormwater control systems,
as well as facility equipment, facility areas, and facility systems that present a potential
for stormwater exposure or stormwater pollution where not already addressed under
another element of the 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.
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

Permit No. NCS000304 DRAFT
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.
8. 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 annual basis. The annual update
shall include:
(a) an updated list of significant spills or leaks of pollutants for the previous three
(3) years, or the notation that no spills have occurred (element of the Site
Overview);
(b) a written re -certification that the stormwater outfalls have been evaluated far
the presence of non-stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on -site stormwater
BMPs (BMP Summary element of the Stormwater Management Strategy).
(d) a review and comparison ofsample analytical data to benchmark values (if
applicable) over the past year, including a discussion about Tiered Response
status. The permittee shall use the Division's Annual Summary Data
Monitoring Report (DMR) form, available from the Stormwater Permitting
Program's website (See: https://deg.nc.gov/about/divisions/energy-mineral-land-
resources/npdes-stormwater-individual.
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 III, 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 (5) years and made
available to the Director or the Director's authorized representative immediately upon
request.

Permit No. NCS000304 DRAFT
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1.
All analytical monitoring shall be performed during a measurable storm event ate c
stormwater discharge outfall (SDO). Only SDOs discharging stormwater associated with
industrial activity must be sampled (See Definitions).
A measurable storm event is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DEMLR Regional Engineer. See Definitions.
The permittee shall compare monitoring results to the benchmark values in Table 1.
Exceedances of benchmark values require the permittee to increase monitoring, increase
management actions, increase record keeping, and/or install stormwater Best Management
Practices (BMPs) in a tiered program. See below the descriptions of Tier One, Tier Two, and
Tier Three response actions below. In the event that the Division releases the permittee from
continued monthly monitoring and reporting under Tier Two or Tier Three, the Division's
release letter may remain in effect through subsequent reissuance of this permit, unless the
release letter provides for other conditions or duration.
The benchmark values in Table 1 are not permit limits but should be used as guidelines for
implementation of the permittee's 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.
Please note that the parameters in the last two rows in Table 1 (non -polar oil and grease
and new motor oil usage) are only required for outfalls that discharge runoff from vehicle
or equipment maintenance areas in which more than SS gallons of new motor oil and/or
hydraulic oil per month is used when averaged over the calendar year.

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

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.
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.
Monitoring periods remain consistent through the permit term and through the renewal process.
Failure to monitor semi-annually per permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified time period. "No discharge" from an
outfall during a monitoring period does not constitute failure to monitor, as long as it is
properly recorded and reported.
Tier One
lf: 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
exceedance, the inspection date, the personnel conducting the inspection, the selected actions, and the
date the selected actions were implemented.
6. Note: Benchmark exceedances for a different parameter separately trigger a tiered res 'onse.
:.. Vert wo'.
If: The first valid sampling results from two consecutive monitoring periods (omitting periods with no
discharge) are above the benchmark values, or outside of the benchmark range, for any specific parameter at
a specific discharge outfall;
Then; The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow" to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, exercise the
option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional
Engineer may direct the response actions on the part of the permittee as provided in Tier Three,
including reduced or additional sampling parameters or frequency.
5. 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
analvtical 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.
This site discharges to a segment of Long Creek that has a Total Maximum Daily Load
(TMDL) approved for turbidity issues. The permitee should assure that all appropriate
BMPs are in place to minimize any impact to this stream segment. This stream segment
also has potential issues with Copper, Iron and total suspended solids. If additional BMPs
are needed to achieve the required level of control for pollutants of concern, the permittee
may 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 REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the Stormwater
Pollution Prevention Plan (SPPP) and identify new potential sources of stormwater
pollution. Qualitative monitoring of stormwater outfalls must be performed during a
measurable storm event.
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed semi-annually
during required analytical monitoring events (unless the permittee is required to perform
further qualitative monitoring per the Qualitative Monitoring Response, below). Inability
to monitor because of adverse weather conditions must be documented in the SPPP and
recorded 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
the discovery. This documentation will be maintained with the SPPP.

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

Effective December 21, 2016 or when the agency's electronic reporting system is able
to accept NPDES stormwater permit monitoring data, the permittee shall report
discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report (eDMR) internet application. NC DEMLR will notify permittees
when eDMR is ready to accept stormwater monitoring data.
Monitoring results obtained during the previous month(s) shall be summarized for each
month and submitted electronically using eDMR. The eDMR system allows permitted
facilities to enter monitoring data and submit DMRs electronically using the internet.
Until such time that the state's eDMR application is compliant with EPA's Cross -Media
Electronic Reporting Regulation (CROMERR), permittees will be required to submit all
discharge monitoring data to the state electronically using eDMR and also will be
required to complete the eDMR submission by printing, signing, and submitting one
signed original and a copy of the computer printed eDMR to the following address;
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due
to the facility being physically located in an area where less than 10 percent of the
households have broadband access, then a temporary waiver from the NPDES
electronic reporting requirements may be granted and discharge monitoring data may
be submitted on paper DMR forms or alternative forms approved by the Director.
Duplicate signed copies shall be submitted to the mailing address above. See "How to
Request a Waiver from Electronic Reporting" section below.

Good catches Bradley — I've updated the narrative to reflect the items below. I'm also sending you an updated topographical map.
We decided we want to include some wording explaining the relationship between the south outfall and the south stormwater
collection pond.
If you have any further questions please let us know.
Thanks,

Subject: RE: [External] FW: Stormwater Permit Renewal Information
Hey Jill,
Thanks for the information. After looking through it real quickly t had a couple of questions.
1.On the Outfall Narrative under South Stormwater Collection Pond it indicates that overflow from the south pond eventually
"..makes its way to Outfall 2:" But the Map of the Water Systems indicates that overflow from the South Pond would go to
the west outfall (Outfall 4). It appears that the narrative should say it flows to Outfali 4? Is that correct? CORRECT, OUTFALL
4.
2. Just making sure about the overflow from the West Pond. Neither the narrative or the water system map indicate anything
about overflow from the west pond but I'm guessing that there is overflow at times from the west pond and it goes out
Outfall 4. Is that correct? We do have a pumping system in the west stormwater collection pared which runs -off of,a level
indicator. When the crater level raises, it pumps over to the south'stormwater collection pond. in the event`thatthe pumps
were to fail, or if we had an extreme weather event, water from the west stormwater collection pond would overflow and
make its way to the.west outfall (outfall 4). This has happened in the past.
3. The Outfall Narrative document seems to indicate that Outfall 4 takes drainage from the overflow from the south pond and
runoff from the top of the landfill. But, the topographic map shows a larger area draining to outfall 4 including much of the
actual plant facility? Could you verify the areas draining to outfall 4? The topographical map'is accurate. The rainfall from
almost the entire mill as indicated on the map is all collected through drainage and basins and is then piped over to. the south
stormwater collection pond where it then follows the narrative for the south stormwater collection pond (i.e. goes to outfall
4 if it overflows). All of this rainfail.capture being sent to the south pond was purposely set up to allow us to capture'this
water for re -use purposes.
Thanks for your help!

Electronic reporting -- EPA regulation do now require electronic reporting of data and some other reports. At this
point our database is not yet ready to support electronic entry of stormwater DMR data. This will happen during
the permit cycle so the language will be in the permit, but at first you will continue to submit DMR data in hard
copy form. When electronic submittal is ready all permitees will be notified. We do still need to gather accurate
latitude/longitude for ou points.

Outfalls - We discussed the outfalls at the facility. It was noted that the facility is set up to capture stormwater and
reuse stormwater in the production process. Actual "process water" is handled in a non -discharge closed loop
recycle system that does not over flow to the stormwater ponds. This system is covered by a DWR Recycle System
permit (WQ0006060). - Correct
Please verify this information and provide narrative information and possibly site doinage info to verify to confirm
the characterization of the outfalls. In our discussions we noted that there are some questions about your outfalls
that would be best addressed as part of the site Yisit with our regional office staff,
*Some, of the narrative provided in your email was incorrect mainly in that it intertwined our outfalls and ponds —
the attached narrative should help clear things up. We have 3 outfalls and 3 stormwater collection ponds. Though
they are named similarly, they are very difi'erent entities. Please reference the attached map and narrative of our
water systems to more clearly understand the flow.
• Monitoring —As 1 noted in our call, we have a summary of your monitoring data for 2010-2013 as part of your
renewal application submitted in 2013. Our records show only a few DMR submittals since that time. Can you
pleases provide a summary of our available data from 2014-the present?
Please see the attached DMR results pdf. All results from 2017 and on were taken by either Bob or myself. Periods
where there is no sample data indicate a period during which there was no discharge.
You asked about monitoring schedule and if this could be placed on an annual cycle. All of our current permits are
set up this way and your renewed permit will required semi-annual monitoring with the first sampling period
January -June and the second July- December.
Sounds good to us — thanks!
In a 2013 inspection report to your facility it was noted that inspection staff had observed dry weather flow that
potentially came from your capped landfill. The report asked for a response on this issue, but we don't have any
record of a response. In our call ygu indicated that you had a copy of this report and would review the findings
Md rovip de a resonse on this issue,
Bob and I started working at the Charlotte Mill in 2017 and were not present for this inspection. We therefore are
not familiar with the specific circumstances of the area at the time of the inspection. To provide an explanation,
we have done some investigation into this situation. We believe the investigation may have seen the very
common dry weather flow that occurs at our landfill after a rain event. Due to the large surface area of the
landfill, it may take several days for all of the surface runoff to make its way to the outfall. We have also done a
review of our landfill inspections and found there to be no indication of any wet or seeping areas. Today, the
landfill and outfall are performing well.
• Oil -Water Separator— It appears that the O/W Separator is no longer in place.
Correct, this oil water separator is out of commission. There are discussions about pulling the equipment out but
for now it has been idled.

.�. ­i It doesn't appear that there have been any major operational, process or site changes since the renewal
application that would impact the potential sources of stormwater pollution. Correct.
• If there is an updated site map that would help witih characterizing rainage areas and outfalls,_an_electrnnic copy.
would be helpfUL
Attached topographical map as well as a water flow map.
You can provide any of the above additional information directly to my attention. There is no need for a formal
application modification submittal. As I•mentioned, once we have a draft permit we will forward toy you for your
comment. Our regional office will also contact you to set up a site visit and it is likely that the Charlotte -Mecklenburg
Stormwater Services staff will participate as well.

OUTFALL NARRATIVE
OUTFALLS --- Our 2009 permit lists 4 outfalls, with the removal of the parking lot outfall we
will have 3 outfalls:
• OUTFALL 1(aka SOUTHEAST OUTFALL): As noted in your email this outfall collects
rainwater strictly from non -industrial activities (i.e_ parking lot and landscaped areas).
We,therefore agree that it should not be covered under the NPDES permit. Our
attached•new topographical.map now notes that this area is 'Non Industrial Activity'.
• OUTFALL 2 faka SOUTH OUTFALL): As indicated in your email there was a project years
ago to help us capture more Stormwater for recycling purposes. This project installed a
pump system at the OUTFALL 2 area which'can handle a 2 year, storm event. The water
' from this outfall is therefore collected and pumped over to the SOUTH STORMWATER
COLLECTION POND. Since the collection/pumping system is only built to withstand a 2
year event, we agree that it should still be;captured in the NPDES permit.
• ' OUTFALL 3 (aka NORTH OUTFALL): The North Outfall is set back in'the woods as
indicated on the attached map. This outfall discharges into a' creek that runs through our
property. ln'the past, we'have not been able to gather samples from this outfall. Due to
the lay of the land, the outfall only discharges during extreme weather events. Last year,
we spoke with Bethany Georgoulias in regards to sampling this outfall. She informed us
tliat•the state -does not require us to go outt into extreme weather events to gather

S►� representative data for this outfall (as well as for Outfall-2 in the'event that we had a
greater than 2 year storm event and it discharged), We discussed this with you as well
and you also referred to 'a 'representative' status for this outfall. We understand that
the permit will not list the outfall as a 'representative' status, but that we can note the
representative status on our DMRs.
• OUTFALL 4 (aka WEST OUTFALLI: The West Outfall is located back in the woods. It is
made up of a culmination of overflow from the South Pond as well as runoff from the
top of the landfill. This runoff and overflow goes through a culvert where it is treated
with CO2, if needed, and then flows into the woods. We sample this outfall at the edge
of our property where it is most accessible.
STORMWATER COLLECTION PONDS — Our site captures Stormwater through the
use of 3 stormwater collection ponds. These are separate and not to be confused with our
outfalls. These ponds are strictly for capturing and holding STORMWATER (except for
the west pond which also collects slag cooling water runoff), they do not hold process
water of any kind. In the event of a severe weather event, the ponds may overflow.
Overflow water will flow to one of our 3 OUTFALLS.
• SOUTH STORMWATER COLLECTION POND: The South Stormwater Collection collects
rainfall runoff from storm drains as well as water from the West Stormwater Collection
Pond. Water from this collection pond is pumped to the North Stormwater Collection
Pond. In the event that this South pond overflows, excess water will pass under a
culvert in the road, flow down the drainage area around the landfill, be treated with
CO2 as needed and then make its way back to DUTFALL �(

RE: Ameristeel Corporation; NCS000304
Dear Bradley Bennett:
NCNHDE-6520
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information
about natural heritage resources for the project referenced above.
Based on the project area mapped with your request, a query of the NCNHP database, indicates that there are
no records for rare species, important natural communities, natural areas, and/or conservation/managed areas
within the proposed project boundary. Please note that although there may be no documentation of natural
heritage elements within the project boundary, it does not imply or confirm their absence; the area may not have
been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists.
In the event that rare species are found within the project area, please contact the NCNHP so that we may
update our records.
The attached `Potential Occurrences' table summarizes rare species and natural communities that have been
documented within a one -mile radius of the property boundary. The proximity of these records suggests that
these natural heritage elements may potentially be present in the project area if suitable habitat exists. Tables of
natural areas and conservation/managed areas within a one -mile radius of the project area, if any, are also
included in this report.
If a Federally -listed species is found within the project area or is indicated within a one -mile radius of the project
area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for guidance. Contact
information for USFWS offices in North Carolina is found here:
https:Nwww.fws.goy/offices/Directo IListO Icg,§.r,fm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation planning, project
review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions.
Information provided by the NCNHP database may not be published without prior written notification to the
NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP
data may not be redistributed without permission.
The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature
Preserve, Registered Heritage Area, Clean Water Management Trust Fund easement, or Federally -listed
species are documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance, please
contact Rodney A. Butler at rodney.butler ncdcr.gov or 919-707-8603.
Sincerely,
NC Natural Heritage Program

Dear Mr. Churchill:
?145 Suttl.e Avenue
Charlotte, NC 2,1208-5237
On October 23, 2017, Matthew Storosh, Chad Broadway and Kristen O'Reilly of
Charlotte -Mecklenburg Storm Water Services (CMSWS) conducted an inspection of the above
referenced facility as a requirement of the City of Charlotte's NPDES Permit, NCS000240, Part II
Section H. Inspection authority is granted by Charlotte City Code Chapter 18, Article III, Section
18-82. At the time of inspection, the facility was observed to be in compliance with the City of
Charlotte Storm Water Pollution. Control Ordinance.
The inspection was also conducted as part of a cooperative working agreement between
Mecklenburg County and the North Carolina Department of Environmental Quality (NCDEQ) ---
Division of Energy, Mineral and Land Resources (DEMLR). NCDEQ W DEMLR has been copied
on this report and made aware of the following observations regarding the facility's NPDES
stormwater permit:
1) Stormwater Pollution Prevention Plan (SPPP)
A Stormwater Pollution Prevention Plan (SPPP) has been developed, recorded, and implemented.
However, several components were missing from the SPPP that are required under NPDES
Individual Permit NCS00034. The facility's SPPP should indicate the year the spill reports are
for, records of annual non-stormwater discharge evaluation of outfalls forms, and secondary
containment discharge lag forms that specify the location of the discharge.
2) Qualitative Monit�rin
Qualitative monitoring has been conducted and recorded.
3) Analytical Monitoring
Analytical monitoring has been conducted and recorded.

DESCRIPTION OF INDUSTRIAL CHANGES

Description of Significant Industrial Changes
The Gerdau Long Steel North America facility has not implemented any significant
changes in industrial activities, during the term of the existing permit, that could
potentially affect the stormwater discharge. There is currently a closed and
capped landfill located on -site. Gerdau plans to pave the landfill to create an
additional parking lot within the duration of the subsequent permit. The new
parking lot will not have an effect on stormwater discharge since the landfill area
is capped, and therefore already considered impervious.

Difficulties with permitting site
Slag quench water- The west pond onsite collects slag quench water which is
combined with the stormwater and pH adjusted. The water from the west pond
eventually ends up in the North Pond. The discharge of the North Pond will be
monitored in this permit.
Slag quench water was treated as a non -issue.
- Feasibility study was done to create a closed loop system and found it
would have a high cost.
Expected parameters in the water are Ca, Mg, and Al. Al is in the
analytical monitoring.
- The quench water is diluted in all three of the ponds onsite.
Based on the site visit and regional office comments we believe the permit
will be protective of surface waters.
2. Capped Landfill- The capped landfill has water draining from it into a stream in
drainage area 3.
- The stormwater is pH adjusted but this would be similar to using a BMP to
remove TSS.
- Outfall will be monitored in the renewal permit to see if any problems
exist.

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000304
Gerdau Ameristeel US Inc.
Mecklenburg County
Dear Mr. Read:
Dee Freeman
Secretary
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.
Outfall 001 has been removed from the monitoring as asked for in the representative outfall letter with the
renewal package because the area is an employee parking that is elevated from industrial activates.
However, the other request in the representative outfall letter for Outfall 004 to represent Outfall 002 will not
be granted. This is because the analytical monitored showed values approaching, or in excess of current
stormwater program benchmarks for BOD, COD, Cd, Cu, Pb, TSS and Zn for Outfall 002 and these values
were even higher than Outfall 004.
The site visit on November 11, 2008 was conducted to evaluate the outfall locations. As far as sampling
locations please do not continue sampling in stream. Instead, samples will be taken in the following places:
Outfall 002 (Southeast): same location as previous permit.
Outfall 003 (North): previous samples were taken in stream at the property line. Now, samples will be taken
at the outlet of the North Pond for drainage area 3.
Outfall 004 (West): previous samples were taken in stream at the property.Iine. Now, samples will be taken
at the outlet near the capped landfill for drainage area 4.
If you have further questions about the sampling locations, please request, again, assistance from the
Mooresville Regional Office.
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
1. Analytical monitoring parameters, BOD, COD, Cd, Cu, Pb, Ni, TSS and Zn, have been maintained in
this permit. Al and Cr have been added to the permit.
2. From the 2008 EPA Multi -Sector General permit, Sector F for Primary Metals recommends adding Al
and Zn based on the SIC code of 3312.

3. Oil & Grease were added.
4. Phenol was removed from the permit because the monitoring results were significantly under the
current benchmarks.
5. Chromium was also added based on the report that it is present in the Electric Arc Furnace Dust
onsite.
G. pH has been added to the analytical monitoring requirements.
7. All analytical monitoring has been set to quarterly 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 three-month sampling period.
8. 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 outfaIl 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 outfaII 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 outfalI where a sampling result exceeded the benchmark
value for two consecutive samples.
9. You are required to conduct aII of the analytical and qualitative monitoring during representative storm
events as defined in Part II Section B. Qualitative monitoring is required regardless of representative
outfall status.
10. In the event that this permit expires, you are responsible to continue all monitoring until the renewal
permit is issued. See Footnote 1 of Tables 1, 4, and 5.
11. The flow reporting requirement has been removed per DWQ's revised strategy. (The total rainfall
parameter is still required in this permit, however.)
12. 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 conduct vehicle maintenance. If the facility begins vehicle maintenance
during the permitted timeframe then the requirements in Section ILD shall apply.
Other permit changes:
1. 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.
2. 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 tAat 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 II Section A.
3. AdditionaI requirements for the Stormwater Management Plan have been specified in Part Il Section A.
More details regarding secondary containment are provided. .
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part I1 Section A.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft. If no
adverse comments are received from the public or from you, this permit will likely be issued in about two
months.

County SR 1606) are rated Impaired due to turbidity and exceedances of the manganese water quality standard.
Ambient data from the current assessment period indicate that the turbidity readings remain in violation of the
state standard. Fecal coliform concentrations are also above the state standard, but Long Creek is not used for
primary recreation. There are no NPDES discharges to this stream, suggesting that impairment is likely a result
of urban runoff, construction and agriculture in the watershed. Many general recommendations were provided
in Section A, Chapter 4, Part 4.13. Part 4.13 focuses on habitat degradation.
http://h2o.enr.statc.ne.us/basinwide/documents/CTBA-4.pdf
4. Threatened and Endangered: On the National Heritage map there is one species (Villosa vaughaniana or
Carolina Creekshell) that is state regulated (E).
5. Location: This discharges to a UT to a classified C stream.
6. Industrial Chances Since Previous Permit: Replaced existing baghouse with a new enclosed baghouse to
control particulates. Upgraded glycol -water recycle cooling system. System is installed in secondary
containment tanks to prevent stormwater contamination, Installation of new co -product hauling road.
7. Analytical Monitoring_ Notes: Samples were taken at four outfalls during the fourth year of the permit. The
benchmarks were exceeded for BOD, Cd, COD, Cu, Pb, TSS and Zn. The values were the highest for outfall
002.
From the 2008 EPA Multi -Sector General permit, Sector F for Primary Metals recommends adding Al and Zn
based on the SIC code of 3312. There is scrap yard onsite that can have 30,000 tons of scrap metal.
Therefore, monitoring for Cd, Cu, Pb, TSS and Zn was maintained for the permit and Al was added. Phenol
was removed from the permit because the monitoring results were under the current benchmarks. Removing
Page 4 of 10

NCS000304
Nickel was considered, but Ni was maintained because of the scrap metal yard onsite and having only 4 data
points. BOD and COD remained in the monitoring because of values over the current benchmarks. Chromium
was also added based on it being in the Electric Arc Furnace Dust onsite. pH is important to include because of
the lime storage.
The representative outfall letter asked for Outfall 004 to represent Outfall 002 and for Outfall 001 to not be
monitored because it has no industrial activity. Outfall 002 has a drainage area that is primarily a road however
the monitoring data is higher for 002 than for 004. The drainage area for Outfall 001 does look to only include
the employee parking lot and no industrial activity. A site visit will probably be necessary to determine
representative outfall status.
Be sure to verify roads and parking area draining to 001 do not include industrial -related traffic (hauling,
loading, etc.).
8. Qualitative Monitoring Notes: The qualitative monitoring was recorded 1 1 times from 9/19/00 to 9/27/04.
Outfall 001 — Some dirt coming from roadway (Lakeview and HW l 15). Event on 3/16/04 had 9s for clarity,
floating solids, and suspended solids. Blue/black color recorded on event. .
Outfall 002 — Dirt from road in many event comments. Red/Black color on 7/25/02 which was from heavily
travelled road for trucks.
Outfall 003 — Light grey color in two events supposedly from slag haul road. The application stated there was a
new slag road created for co -product hauling road.
Outfall 004 — 12/13/01 muddy water from construction operation. Reddish Brown Color.

Revised Permit Recommendations: Analytical Monitoring:
1. Maintaining BOD, Cd, COD, Cu, Pb, Ni, TSS and Zn. Removing Phenol. Al and Cr are added to the
monitoring.
2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part 11
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.
4. 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 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.
5. The,pennittee is required to collect all of the analytical and qualitative monitoring samples during
representative storm events as defined in Part 11 Section B. Qualitative monitoring is required regardless of
representative outfall status.
6. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote I of Tables 1,
4, and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
8. 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 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 II
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.

Discussions with permittee: Permit Contact Timothy L. Keesling 704-596-0361 x 3048
Renewal Application and Request for Representative outfall:
Timothy Keesling left the company in the spring but is still helping out with questions as they look for a new
environmental manager. Talked with Timothy Keesling on 09/29/08.
Corporate contact is Sunny Crews 813-505-2864
Plant Manager is Casimro Lidorio 704-596-0361
1. Have there been any changes since the application was submitted? No
2. What type of steel plant is it? They use 100% recycled scrap. Melted and alloys are added. They make billets
and then store them. Billets are sold or made into rebar, channels, etc. Biggest stormwater issue onsite would
be the scrap yard that can have 30, 000 tons of scrap metal.
3. Is there any discharge from any of the three ponds? Some discharges in very wet weather.
4. It looks like there are some high values in your analytical monitoring, especially at Outfall 2. Any reason for that?
The drainage area is primarily road and there used to be sediment and materials on the road. Since the
monitoring, they have increased their maintenance of the road
5. What materials are stored outside? What is the co -product? Scrap metal and carbon and lime in bags. The co -
products are steel slag and mill scale (rust). The mill scale is sold to the cement industry.
6. Asked for representative outfall for outfall 002. The analytical monitoring shows outfall 002 as the worst outfall.
Why would that be? They had poor maintenance that has supposedly changed.
7. Vehicle Maintenance? Yes. It is contracted out but the contractor comes to the vehicle.
8. What is your SIC code? 3312

NCS000304
Site Visit 11/6/08
Mike Parker, Brian Lowther, Ken Pickle, and Cory Larsen met with Charlie Blubaugh of Gerdau Ameristeel
The main purpose of the site visit was to examine the stormwater outfalls. Currently, the permittee was using two
streams to collect their samples for outfalls 003 and 004.
Issues that was raised at the site visit:
Outfall 001 and 002 were evaluated. Outfall 001 was employee parking that was elevated from other industrial
activates and will not require analytical sampling. Outfall 002 was primarily a haul road. The analytical
monitoring was high for this area. This is probably because of the trucks dropping off loads of scrap metal and then
leaving on the haul road. Outfall 002 will need to be sampling in the renewal permit.
Water is pumped from the West pond to the South pond and then to the North pond. The water from the North
pond is being used in a couple different ways. One is to be pumped to the slag staging area where it is used as a
contact coolant. The water sprayed on the slag then drains into the west pond. West pond is also added CO, in
order to treat the water. Therefore, there is some comingling of process water and stormwater.
Where should the samples locations be for drainage areas 3 and 4? Sample the outlet of the North pond for
drainage area 3 and sample the outlet near the capped landfill for drainage area 4.
The capped landfill has water draining from it into a stream in drainage area 3
Oil & Grease was added to the analytical monitoring.
Special Issues Explanation:
This permit will be renewed as an individual NPDES stormwater permit. The west pond onsite collects slag
quench water which is combined with the stormwater and pH adjusted. The water from the west pond
eventually ends up in the North Pond. The discharge of the North Pond will be monitored in this permit. Also,
the facility operates near zero discharge operation. During a site visit on November 11, 2008 there was a
discharge coming from the North Pond but this event was atypical because the plant was not running.

Just following up on our conversation. I am concerned about the fact that the slag quench water is not specifically
mentioned in the permit as an allowable non-stormwater discharge or in some other way addressed by the permit
or supporting documentation. I think we all have a mutual understanding of the situation but I am concerned about
the possibility of a misunderstanding with future inspectors and permit writers. I am also concerned about the
permit requirement to certify that outfalls are free of non-stormwater in this situation.
Please take some time to review this issue and let us know what the best approach would be. I will follow up'in a
week.

Enclosed with this letter is a copy of the draft stormwater per it for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditi s and requirements it contains.
Outfall 001 has been removed from the monitoring as asked for in a representative outfall letter with the
renewal package because the area is an employee parking that is ele 4esorBOD,COD,Cd,Cu,Pb,TSSand

However, the other request in the representative outfall letter for Out4 to represent Outfall 002 will not
be granted. This is because the analytical monitored showe h val
Zn for Outfall 0 1'these values were even higher than-Outfall 004. 1 t
The site visit on November 11, 2008 was conducted to evaluate the outfall locations. As far as sampling
locations please do not continue sampling in stream. Instead, sample e taken in the following places:
Outfall 002 (Southeast): same location as previous permit.
Outfall 003 (North): previous samples were taken in stream at the property line. Now, samples will be taken
at the outlet of the North Pond for drainage area 3.
Outfall 004 (West): previous samples were taken in stream at the property line. Now, samples will be taken
at the outlet near the capped landfill for drainage area 4.

5. Chromium was also added based ot�he Electric Arc Furnace Dust onsite.
6. pH has been added to the analytical monitoring.re�quirements.
7. All analytical monitoring has been setquarterly during a representative storm event as defined in fart
II Section B. The permittee must also documOnt the total precipitation for each event. If no discharge
occurs during the sampling period, the permit�ee must submit a monitoring report indicating "No Flow"
within 30 days of the end of the three-month s pling period.
8. Benchmarks for analytical monitoring have bee added to this draft permit. Exceedances of benchmark
values require the permittee to increase monitor ng, increase management actions, increase record
keeping, and/or install stormwater Best Manage Zent Practices (BMPs) in a tiered program. If the
sampling results are above a benchmark value, o outside of the benchmark range, for any parameter at
any outfall then the facility shall follow the Tier 1 7uidelines 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.
9. You are required to conduct all of the analytical and ualitative monitoring during representative storm
events as defined in Part II Section B. Qualitative monitoring is required regardless of representative
outfall status.
10. In the event that this permit expires, you are responsible to continue all monitoring until the renewal
permit is issued. See Footnote I of Tables 1, 4, and 5.
11. The flow reparting requirement has been removed per + WQ's revised strat g-(=I= , o a •rainfall
parameter is still required in this permit, however.)
12. Vehicle maintenance monitoring has been revised semi-annttall in order -to coincide with analytical
and qualitative monitoring. This requirement appears in all Individual-Stormwater permits, ho.. -. -. jt
only applies to facilities that conduct vehicle maintenance. If the facility begins vehicle maintenance
during the permitted timeframe then the requirements in Section II.D shall apply.
Other permit changes:
1. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part lI
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.
2. 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 II Section A.
3. Additional requirements for the Stormwater Management Plan have been specified in Part lI Section A.
More details regarding secondary containment are provided.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in ]'art II Section A.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft. If no
adverse comments are received from the public or from you, this permit will likely be issued in about two
months.

Dear Mr. Read:
The Division of Water Quality's Stormwater Permitting Unit (SPU) acknowledges receipt of
your renewal application for coverage under NPDES Permit Number NCS000304 on January 24, 2005.
We apologize for the lengthy delay in responding to your submittal and are now making every effort to

progress on individual permits over the next six'months to reduce our backlog.
We are currently beginning our review of your renewal application. Please continue to comply
with all conditions and monitoring requirements in your expired NPDES stormwater permit. As
long as you have submitted a complete renewal request package and maintain compliance with those
permit conditions, stormwater discharges from this facility are authorized by that permit until the
Division issues a renewal permit or notifies you of an alternative action.
No additional information is required at this time, but we may contact you in the future. Please
notify us if any significant changes have taken place at this facility since you submitted the renewal

Re: NPDES Permit No. NCS000304 — Renewal Application and Request for Representative
Outfall Status
Gerdau Ameristeel US Inc.
Mecklenburg County
Dear Mr. Bennett:
Enclosed herewith are two (2) copies of the Renewal Application for the above referenced
permit.
Please note that analytical and qualitative monitoring was performed at all outfalls as required in
the previous permit.
We currently have four (4) stormwater outfalls. Based on our review of drainage patterns,
storage locations of significant materials and process activities, we hereby request that the South
outfall 002, be granted "Representative Outfall" status. Based on our review of the drainage
areas, runoff at Outfall 004 is representative of stormwater discharged from Outfall 002 at the
Gerdau Ameristeel site. Another stormwater outfall, the Southeast Outfall 001, consists solely of
the employee parking lot and drainage from the public roads bordering the facility, and therefore
we request that monitoring requirements for Outfall 001 be eliminated, as there are no activities
associated with industrial activity in this drainage area.
A description of the materials and industrial activities within each of the areas draining to
Outfalls 001, 002, 003 and 004 is provided below. Please refer to the attached Stormwater
Drainage Map (Figure 5) and Figure 6, Location of Significant Materials.
Charlotte Steel Mill
P.O. Box 481980 - 6601 Lakeview Road - Charlotte, North Charlotte 28269 - (704) 5964)361 - Fax: [phone]

Southeast Outfall 001
Southeast Stormwater Outfall 001 is located along the Southeast corner of the Gerdau
Ameristeel property and drains 2.6 acres. This drainage area consists solely of the
employee parking lot, along with drainage for the roadway right-of-way areas of Old
Statesville Road and Lakeview Road not owned by Gerdau Ameristeel. As defined in 40
CFR 122, Stormwater Discharge Associated With Industrial Activity "excludes areas
located on plant lands separate from the plant' s industrial activities, such as office buildings
and accompanying parking lots as long as the drainage from the excluded areas is not mixed
with stormwater drained from the above described areas".
Based on the attached drainage map, the Southeast Outfall 001 at Gerdau Ameristeel does
not drain any plant lands associated with industrial activity, therefore, we request that this
outfall excluded from additional qualitative monitoring or analytical monitoring
requirements.
South Outfall 002
South Stormwater Outfall 002 is located along the South border of the Gerdau Ameristeel
property and drains 4.2 acres. This drainage area consists of the right-of-way along
Lakeview Road, as well as plant drainage along the truck roadway and rail spurs along the
South edge of the plant building. There is no storage of significant materials in this
drainage area. Process activities in this drainage area consist solely of truck and rail traffic
to/from storage areas draining to the West Stormwater Outfall 004.
North Outfall 003
North Outfall 003 is located along the Northwest corner of the Gerdau Ameristeel property.
This outfall compresses one of the two main stormwater outfalls for the facility, and drains
49.1 acres. Significant materials stored in this drainage area include equipment storage, co -
product storage, oil storage, steel billet storage, as well drainage from production areas and
undeveloped property (approximately 32 acres) drainage, including right-of-way drainage
along Old Statesville Road.

West Outfall 004
West Stormwater Outfall 004 is located along the West border of the Gerdau Ameristeel
property. This comprises one of the two main stormwater outfalls for the facility, and drains
56.2 acres. Significant materials stored in this drainage area include finished steel product,
scrap metal raw material, co -product storage areas, as well as rail yard, production area, and
fuel oil storage area drainage.
Based on the activities and storage of materials within each outfall drainage area, we feel that .
analytical stormwater sampling conducted at Outfall 004 would provide worst -case
representative quantitative stormwater data from Outfall 002, as Outfall 004 includes outdoor
storage areas, truck traffic,, and rail traffic areas for raw material, co -product and finished product
which is only transported through the Outfall 002 drainage area.
If you have any questions or comments on the above, please do not hesitate to contact me at
[phone] x 3048.
