Subject: Final NPDES Stormwater Permit
Permit No. NCS000346
Insteel Wire Products Company
Surry County
Dear Ms. Ellis:
In response to your renewal application for continued coverage under NPDES stormwater permit
NCS000346, the Division of Energy, Mineral and Land Resources 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 no major changes from the draft permit sent to you on April 3, 2018.
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 I11, 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.
Division staff performed a site visit at your facility on June 4, 2018. In this process some questions
were raised concerning the number of stormwater outfal is on your property, drainage areas for the
outfalls and the final discharge locations for the outfalls. The Division's Winston-Salem Regional
Office will be sending you an inspection report detailing the issues from the site visit. You will need
to evaluate these issues and provide the Division with information to better characterize the drainage
and discharge points at your facility. With these issues in mind, the Division feels that your current
representative outfall designation may be inadequate to characterize the discharges from your facility.
With this permit issuance we are requesting that you begin monitoring at all outfalls in accordance
with the analytical and qualitative monitoring requirements of the permit. Once your evaluation is
complete and you have completed one year of monitoring you can request representative outfall status
from our Division.

Permit No. NCS000346
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 (NOI) 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.

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 111, Standard
Conditions, Section B, 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.
Part II Page 1 of 12

Permit No. NCS000346
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The permittee shall re -certify annually that the
stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. The certification statement will be signed in accordance with the
requirements found in Part III, Standard Conditions, Section B, Paragraph 3.
2. Stormwater Management Strategy. The Stormwater Management Strategy shall
contain a narrative description of the materials management practices employed which
control or minimize the stormwater exposure of significant materials, including
structural and nonstructural measures. The Stormwater Management Strategy, at a
minimum, shall incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to rainfall and run-on Flows. Wherever practical, the
permittee shall prevent exposure of all storage areas, material handling operations,
and manufacturing or fueling operations. In areas where elimination of exposure is
not practical, this review shall document the feasibility of diverting the stormwater
run-on away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section 313
of Title III of the Superfund Amendments and Reauthorization Act (SARA) water
priority chemicals; and storage in any amount of hazardous substances, in order to
prevent leaks and spills from contaminating stormwater runoff. A table or summary
of all such tanks and stored materials and their associated secondary containment
areas shall be maintained. If the secondary containment devices are connected to
stormwater conveyance systems, the connection shall be controlled by manually
activated valves or other similar devices (which shall be secured closed with a
locking mechanism). Any stormwater that accumulates in the containment area
shall be at a minimum visually observed for color, foam, outfall staining, visible
sheens and dry weather flow, prior to release of the accumulated stormwater.
Accumulated stormwater shall be released if found to be uncontaminated by any
material. Records documenting the individual making the observation, the
description of the accumulated stormwater, and the date and time of the release
shall be kept for a period of five (5) years. For facilities subject to a federal oil Spill
Prevention, Control, and Countermeasure Plan (SPCC), any portion of the SPCC Plan
fully compliant with the requirements of this permit may be used to demonstrate
compliance with this permit. The Division may allow exceptions to secondary
containment requirements for mobile refuelers, as with the exemption provided by
amendments to federal SPCC regulations, as long as appropriate spill containment
and/or diversionary structures or equipment is used to prevent discharge to surface
waters. Exceptions do not apply to refuelers or other mobile tankage used primarily
as bulk liquid material storage in a fixed location in place of stationary containers.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs
Part 11 Page 2 of 12

Permit No. NCS000346
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.
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 U

Permit No. NCS000346
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.
$. 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 for
the presence of non-stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on -site stormwater
BM Ps (BMP Summary element of the Stormwater Management Strategy).
(d) a review and comparison of sample analytical data to benchmark values (if
applicable) over the past year, including a discussion about Tiered Response
status. The permittee shall use the Division's Annual Summary Data
Monitoring Report (DMR) form, available from the Stormwater Permitting
Program's website (See: https://deq.nc.gov/about/divisions/energy-mineral-
land-resources/npdes-stormwater-individuall.
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 1I1, 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 BM Ps 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
BM Ps 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.
Part II Page 4 of 12

Permit No. N6000346
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 permittee
obtains approval from the local DEMLR Regional Engineer. See Definitions.

Footnotes:
1 Measurement Frequency: Twice per year (unless other provisions of this permit prompt monthly
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.
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"
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
Part 11 Page 5 of 12

Permit No. NCS000346
of benchmark comparison and Tiered response actions, the permittee shall use the
analytical results from the first sample with valid results within the monitoring period.

Footnotes:
1 Maintain semi-annual monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded. The permittee must submit an application for renewal of coverage
before the submittal deadline (180 days before expiration) to be considered for renewed coverage
under the permit. The permittee must continue analytical monitoring throughout the permit
renewal process, even if a renewal permit is not issued until after expiration of this permit
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "No Flow" or "No Discharge" within 30 days of the end of the sampling period.
3 Monitoring periods remain consistent through the permit term and through the renewal process.
Failure to monitor semi-annually per permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified time period. "No discharge" from an
outfall during a monitoring period does not constitute failure to monitor, as long as it is
properly recorded and reported.
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 (BM Ps) 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 11 Page 6 of 12

Permit No. N6000346
Tier One
If: The first valid sampling results are above a benchmark value, or outside of the benchmark range, for any
parameter at any outfall;
Then: The permittee shall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving sampling
results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential, and select the specific feasible: source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern, and/or to bring concentrations
within the benchmark range.
4. Implement the selected feasible actions within two months of the inspection.
5. Record each instance of a Tier One response in the 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 parameter separately trigger a tiered response.
Tier Two
If: The first valid sampling results from two consecutive monitoring periods (omitting periods with no
discharge) are above the benchmark values, or outside of the benchmark range, for any specific parameter at
a specific discharge outfall;
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow" to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, exercise the
option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional
Engineer may direct the response actions on the part of the permittee as provided in Tier Three,
including reduced or additional sampling parameters or frequency.
S. Maintain a record of the Tier Two response in the 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;

1 Measurement Frequency: Twice per year during a measureable storm event (unless other provisions of
the permit prompt monthly sampling), until either another permit is issued for this facility or until this
permit is revoked or rescinded. See Table 2 for schedule of monitoring periods through the end of this
permitting cycle. 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 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 gauge 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 II
Section B.
Monitoring results shall be compared to the benchmark values in Table S. The benchmark
values in Table 5 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) in response to a
tiered program. See description of tiers and required response in Part If Section B.

SECTION D: 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.

Footnotes:
1 Monitoring Frequency: Twice per year during a measureable storm event unless other provisions of this
permit prompt monthly monitoring. See Table 2 for schedule of monitoring periods. The permittee must
continue qualitative monitoring throughout the permit renewal process until a new permit is issued.
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.
itative Monitoring Res
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.
SECTION E: SPECIAL CONDITIONS
A (1.) ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)]

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

If a permittee is unable to use the eDMR system due to a demonstrated hardship or due
to the facility being physically located in an area where less than 10 percent of the
households have broadband access, then a temporary waiver from the NPDES
electronic reporting requirements may be granted and discharge monitoring data may
be submitted on paper DMR forms or alternative forms approved by the Director.
Duplicate signed copies shall be submitted to the mailing address above. See "How to
Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DM is due no later than 30 days from
the date the facility receives the sampling results from the laboratory.
2. How to Reguest a Waiver from Electronic RepoEjLug
The permittee may seek a temporary electronic reporting waiver from the Division. To
obtain an electronic reporting waiver, a permittee must first submit an electronic
reporting waiver request to the Division. Requests for temporary electronic reporting
waivers must be submitted in writing to the Division for written approval at least sixty
(60) days prior to the date the facility would be required under this permit to begin
submitting monitoring data and reports. The duration of a temporary waiver shall not
exceed 5 years and shall thereupon expire. At such time, monitoring data and reports
shall be submitted electronically to the Division unless the permittee re -applies for and
is granted a new temporary electronic reporting waiver by the Division. Approved
electronic reporting waivers are not transferrable. Only permittees with an approved

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.
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.

Review of Permit Renewal — NCS000346
Insteel Wire Products Company
• SIC 3315 — Steel Wiredrawing, Steel Nails and Spikes. Facility produces steel wire reinforcing materials for concrete
construction.
• Monitoring — The facility's last permit required monitoring for TSS, COD, Cd, Pb, Al, Zn, Oil & Grease and pH.
Monitoring reported as part of the renewal showed cadmium, lead and oil & grease numbers consistently below the
benchmark values. These parameters have been removed from the permit. Previous permit did have tier system.
o TSS benchmark exceeded three times since the last permit. This is a base parameter, maintain.
o COD has also exceeded a few times and should be maintained.
o Al has consistently been above the benchmark value and should be maintained.
o Zinc numbers exceed the old benchmark a few times. Benchmark value was recently increased and this
would result in no exceedances. Maintain for this permit cycle.
o Maintain pH as a base parameter.
o Parameters remaining in permit — TSS, COD, Total Recoverable Al, Total Recoverable Zn and pH
o Tier structure adjusted to have the three levels as in current permits.
o Parameter codes added to permit.
o Note that facility provided summary of monitoring data but it doesn't appear that monitoring information
has been coming to Central Files accurately. No DMRs for 2016, 17 or 18 and 2013 and 14 in LF were just
the chain of custody forms.
• Facility drains to a UT to Lovills Creek in the Yadkin Pee -Dee River Basin, a class C stream. 2014 Assessment Report
12-72-14-2 shows no impairments except for the statewide mercury listing but no indication of concerns from this
facility. File review of the outfalls indicate that the facility may also have a discharge to Ararat River (12-72-(4.5)j.
Asked region to check this on site visit to confirm.
• Facility has four outfall points but three appear to combine to discharge at one point from the facility (Outfall 002)
• Facility monitors Outfall 002 as representative outfall (approved in 2009). This discharges to Lovills Creek.
• NC National Heritage review — Report shows no record of species of concern.
• Owner and facility name in BIMS was Insteel Wire Products. NC Sec of State did not show this company. Did have
Insteel Wire Products Company. Stephanie Ellis confirmed that this should be the Owner. Leave Facility name as is.
• WSRO — Draft permit and related information sent to the region for comment by email on 4/3/18. Region was asked
to check on the outfalls to multiple streams issue. WSRO has limited staff available at the present time and Sue
White has taken a job in the Central Office. Email to Matt and Sue on status 5/23. Matt responded that Central
Office should handle permits. 5/29 —Sue will inspect this and Southeastern Foundries. Maybe a few others.
Sue White, Alaina Morman and Brandon Wise inspected the site on June 4, 2018. They found issues with the outfall
locations. There appear to be more outfalls than are indicated on the plans and there is some uncertainty about the
drainage areas and discharge points. The inspection report will ask that the facility evaluate these issues. It may be
possible that some extra outfalls can be eliminated with berms, etc. to send flow to existing outfalls. There is a
concern that previously approved ROS may not accurately characterize the discharges. Brandon will work with Sue
to develop an inspection report that goes through the issues and goes through the process with them. The facility
should monitor all outfalls for the first year and can then go through the ROS process again down the road. This
issue has been addressed in the permit issuance cover letter.

Dear Ms. Ellis:
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 It, 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 11, Section A.
3. Monitoring requirements in the draft permit have changed slightly from the previous permit.
Monitoring is proposed for Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Total
Recoverable Aluminum (At), Total Recoverable Zinc (Zn) and pH. Monitoring reported in your renewal
application showed results for Cadmium (Cd) and Lead (Pb) below the reportable limit from 2009
through 2017. The draft permit proposes to remove these parameters, Comments from our regional
staff or other information may result in maintaining these parameters if it is apparent that your activities
in some way have the potential to release them.
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.

Please note that our records for the last few years do not show accurate submittal of monitoring results.
The only records on file are two submittals that were copies of the chain of custody form for the
sampling. Final monitoring results should be submitted on Discharge Monitoring Report (DMR) forms as
outlined in the permit conditions.
4. Vehicle maintenance (Tables 4 & 5) monitoring parameters have been revised. Non -Polar Oil &
Grease [EPA Method 1664 (SGT-HEM)] replaces Oil & Grease/TPFf_ 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.
5. Language has been added under Part 11 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 111,
Section A, 2(b) and (g).
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 bra_ diey_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 noticein 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].

Permit No. NCS000346 DRAFT
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 [NO[) 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.

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 I11, 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 Iist of significant spills or leaks of pollutants during the previous three (3) years
and any corrective actions taken to mitigate spill impacts.
Part I I Page 1 of 13

Permit No. NCS000346 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.
2. Stormwater Management Strategy. The Stormwater Management Strategy shall
contain a narrative description of the materials management practices employed which
control or minimize the stormwater exposure of significant materials, including
structural and nonstructural measures. The Stormwater Management Strategy, at a
minimum, shall incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to rainfall and run-on flows. Wherever practical, the
permittee shall prevent exposure of all storage areas, material handling operations,
and manufacturing or fueling operations. In areas where elimination of exposure is
not practical, this review shall document the feasibility of diverting the stormwater
run-on away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section 313
of Title III of the Superfund Amendments and Reauthorization Act (SARA) water
priority chemicals; and storage in any amount of hazardous substances, in order to
prevent leaks and spills from contaminating stormwater runoff. A table or summary
of all such tanks and stored materials and their associated secondary containment
areas shall be maintained. If the secondary containment devices are connected to
stormwater conveyance systems, the connection shall be controlled by manually
activated valves or other similar devices (which shall be secured closed with a
locking mechanism). Any stormwater that accumulates in the containment area
shall be at a minimum visually observed for color, foam, outfall staining, visible
sheens and dry weather Flow, prior to release of the accumulated stormwater.
Accumulated stormwater shall be released if found to be uncontaminated by any
material. Records documenting the individual making the observation, the
description of the accumulated stormwater, and the date and time of the release
shall be kept for a period of five (5) years. For facilities subject to a federal oil Spill
Prevention, Control, and Countermeasure Plan (SPCC), any portion of the SPCC Plan
fully compliant with the requirements of this permit may be used to demonstrate
compliance with this permit. The Division may allow exceptions to secondary
containment requirements for mobile refuelers, as with the exemption provided by
amendments to federal SPCC regulations, as long as appropriate spill containment
and/or diversionary structures or equipment is used to prevent discharge to surface
waters. Exceptions do not apply to refuelers or other mobile tankage used primarily
as bulk liquid material storage in a fixed location in place of stationary containers.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs
Part 11 Page 2 of 13

Permit No. NCS000346 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.
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.
S. Facility Inspections. Inspections of the facility and all stormwater systems shall occur
as part of the Preventative Maintenance and Good Housekeeping Program at a
minimum on a semi-annual schedule, once during the first half of the year (January to
June), and once during the second half (July to December), with at least 60 days
separating inspection dates (unless performed more frequently than semi-annually).
These facility inspections are different from, and in addition to, the stormwater
discharge characteristic monitoring at the outfalls required in Part II B, 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 i I Page 3 of 13

Permit No. NCS000346 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.
S. 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 for
the presence of non-stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on -site stormwater
BMPs (BMP Summary element of the Stormwater Management Strategy).
(d) a review and comparison of sample analytical data to benchmark values (if
applicable) over the past year, including a discussion about Tiered Response
status. The permittee shall use the Division's Annual Summary Data
Monitoring Report (DMR) form, available from the Stormwater Permitting
Program's website (See'Monitoring Farms' here:
http://deq.nc.gov/about/divisions/energy-mineral-land-resou rces lenergy�
mineral -land- ermits stormwater- ermits n des-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 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. NCS000346 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 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 permittee
obtains approval from the local DEMLR Regional Engineer. See Definitions.

1 Measurement Frequency: Twice per year (unless other provisions of this permit prompt monthly
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.
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"
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
Part II Page 5 of 13

Permit No. NCS000346 DRAFT
of benchmark comparison and Tiered response actions, the permittee shall use the
analytical results from the first sample with valid results within the monitoring period.

Footnotes:
1 Maintain semi-annual monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded. The permittee must submit an application for renewal of coverage
before the submittal deadline (180 days before expiration) to be considered for renewed coverage
under the permit. The permittee must continue analytical monitoring throughout the permit
renewal process, even if a renewal permit is not issued until after expiration of this permit.
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "No Flow" or "No Discharge" within 30 days of the end of the sampling period.
3 Monitoring periods remain consistent through the permit term and through the renewal process.
[May consider adding comment if permit is issued with little time to conduct monitoring during one
of the listed periods.]
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.
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.
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 parameter separately trigger a tiered response.
Tier Two
If: The first valid sampling results from two consecutive monitoring periods (omitting periods with no
discharge) are above the benchmark values, or outside of the benchmark range, for any specific parameter at
a specific discharge outfall;
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No 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 D6MLR 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.
Part 11 Page 7 of 13

107117[i►lam►DR11IlhICf,h'f 11MA21
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 DEM LR 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.
SECTION C: ON -SITE VEHICLE MAINTENANCE MONITORING REQUIREMENTS
Facilities that have any vehicle maintenance activity occurring on -site which uses more
than 55 gallons of new motor oil per month when averaged over the calendar year
shall perform analytical monitoring as specified below in Table 4. All analytical
monitoring shall be performed during a measureable storm event at all stormwater
discharge outfalls (SDOs) that discharge stormwater runoff from vehicle maintenance areas,
and in accordance with the schedule presented in Table 2 (Section B).

permitting cycle. 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 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.
Part 11 Page 8 of 13

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 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 II
Section B.
Monitoring results shall be compared to the benchmark values in Table 5. The benchmark
values in Table 5 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) in response to a
tiered program. See description of tiers and required response in Part If Section B.

SECTION D: 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.
ve Monito
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.

Part III of this permit (Standard Conditions far NPDES Permits):
• Section B. (3.) Signatory Requirements
• Section D. (6.) Records Retention
• Section E. (1.) Discharge Monitoring Reports
• Section E. (2.) Submitting Reports
1. Reporting Requirements [Supplements Section E. (1.) and Supersedes Section E.
L"
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

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.

Permit No. NCS000346 DRAFT
Regardless of the submission method, the first DMR is due no later than 30 days from
the date the facility receives the sampling results from the laboratory.
2. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To
obtain an electronic reporting waiver, a permittee must first submit an electronic
reporting waiver request to the Division. Requests for temporary electronic reporting
waivers must be submitted in writing to the Division for written approval at least sixty
(60) days prior to the date the facility would be required under this permit to begin
submitting monitoring data and reports. The duration of a temporary waiver shall not
exceed 5 years and shall thereupon expire. At such time, monitoring data and reports
shall be submitted electronically to the Division unless the permittee re -applies for and
is granted a new temporary electronic reporting waiver by the Division. Approved
electronic reporting waivers are not transferrable. Only permittees with an approved
reporting waiver request may submit monitoring data and reports on paper to the
Division for the period that the approved reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver
are found on the following web page:
http: //deq.nc.gov/about/divisions/water-resources/edmr
3. Signatory Requirements (Supplements Section B. (3.) fb) and Supersedes Section
B. (3.] [dl�
All eDMRs submitted to the permit issuing authority shall be signed by a person
described in Part III, Section B. (3.)(a) or by a duly authorized representative of that
person as described in Part 111, Section B. (1)(b). A person, and not a position, must be
delegated signatory authority for eDMR reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an

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.
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.

Q,.

The maps below show the two different HUCs that cross the site. I think that three of the outfalls
probably go to Lovills Creek in the NE part of the map (see first map that shows the stream names).
Outfall 001 may drain to the Ararat River in the SE part of the map (see above)

Bradley,
Please see my comments below in red in response to your information requests. I've attached a redlined copy of the contact
sheet in regards to your last question. We'll speak with you tomorrow morning.
I'd like to have information about your industrial process and whether any things have changed at the facility
since the renewal request was submitted in 2013. Including process changes or facility changes (new
construction, etc.). There have been no process or product changes since the 2013 renewal request was
submitted. New equipment has been installed inside the facility under roof for production capacity and yield
improvement purposes; this equipment does not change the core process and does not introduce new
materials that affect Stormwater discharges.
If there have been and facility changes please provide an updated site map. There have been no external
facility changes.
We'd like to get an updated summary of your analytical data from your monitoring efforts since the previous
renewal application - 2014 through 2017. Also, if there are new activities or materials that would make
new pollutant parameters available to be introduced to Stormwater, please let me know about those.
Summary data for 2014 — 2017 are listed below. There have been no new processes, activities or materials
that would make new pollutant parameters available to be introduced since the 2013 renewal submittal.

EPA passed rules a few years ago requiring electronic reporting of monitoring data. We are working to get
our system to handle this, so hard copy DMRs are still required right now. We are collecting info to help us
as we move toward electronic reporting. So, we will need to get accurate locations (latitude and longitude)
for all of your outfall points. Outfall point locations are listed below. Please note that Outfall #2 serves as
the Representative Outfall for the facility as approved in April 2009 by NCDENR

I have attached a file with what we currently have in our database for contact information. Please look at
this and let me know about any updates/additions. Redlined contact list attached to this email. Please note
that the address of the site changed from 129 Carter St to 1510 Carter St a few years ago when the local
postal authority renumbered the street. The facility has not moved nor have the outfalls. This change is
noted in the contact list.
Please provide other information that you think will be helpful in the review for renewal.
We can discuss any questions you have tomorrow in our meeting.

Stephanie,
Thanks forgetting back in touch. First let me apologize for how long it has taken us to get going on your permit renewal.
A number of issues over the last few years have led to a backlog on renewal of our Individual permits. I will be working on
the renewal and I would like to have a chance to talk about any potential updates/changes since the previous renewal
application came in back in 2013. would like to setup a time where I can call and talk about your facility and the renewal.
I work part time so I'm not in the office every day. I'm out of the office tomorrow. Next week, it looks like I will most likely be
in the office Monday, Tuesday and Wednesday, but I can be available other days for a call if needed. Please let me know
when we may be able to talk. Also let me know the best number that I can call you at.
Below are some potential items for discussion.

Hi Brad,
We received your voicemail today regarding the stormwater permit renewal for our Mount Airy facility. We
weren't able to connect on the phone, so please let us know when you would like to meet to discuss information
and the process for renewing the permit. I am the new EHS lead for the company and Greg Brown (whom you
called and is copied on this email) is the General Manager for the Mount Airy facility; we are both the appropriate
contacts for the permit.
If there are specific items or information you would like for us to have available prior to the meeting, please advise
as that will allow Greg and me to collect that in advance.
We look forward to your response.
Thanks,

RE: Insteel Wire Products; NCS000346
Dear Bradley Bennett:
NC N H DE-5628
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information
about natural heritage resources for the project referenced above.
A query of the NCNHP database, based on the project area mapped with your request, indicates that there are
no records for rare species, important natural communities, natural areas, 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 surreys 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 and is
included for reference. Tables of natural areas and conservation/managed area within a one -mile radius of the
project area, if any, are also included in this report.
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 (DNP), Registered Heritage Area (RHA), Clean Water Management Trust Fund (CWMTF) 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 rod ney.butlerO-ncdcr.gov or 919.707.8603.
Sincerely,
NC Natural Heritage Program

Best Management Practices
1.) Spill prevention and response — an emergency response plan has been established to address
and respond to any spills from oil or hazardous materials either on or off the property.
2.) Preventative maintenance and good housekeeping — this is designed to maintain a clean, orderly
facility. These two subjects shall provide some degree of environmental protection, with special
focus on the IWP storm water system.
3.) Employee Training — the purpose is to teach personnel at all levels of responsibility the
components and goals of the SWP3. When properly trained, personnel are more capable to
prevent spills, respond safely and effectively to an accident when one occurs, and recognize
situations that could lead to storm water contamination.
4.) Visual Inspections — Inspection of the facility will occur on a semi-annual basis. It will include but
not limited to areas around equipment, material storage, material handling areas, outdoor
processing areas, waste generation and storage ares, storm water management devices such as
ditches, etc, wash pits and cooling towers.
5.) Record keeping and reporting — complete records will be kept for each measurement, sample,
inspection or maintenance activity performed or taken pursuant to the requirements of the
permit.

Subject: Final NPDES Stormwater Permit
Permit No. NCS000346
Insteel Wire Products
Surry County
In response to your renewal application for continued coverage under NPDES stormwater permit
NCS000346, the Division of Energy, Mineral and Land Resources 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 no major changes from the draft permit sent to you on April 3, 2018.
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.
Division staff performed a site visit at your facility on June 4, 2018. In this process some questions
were raised concerning the number of stormwater outfalls on your property, drainage areas for the
outfalls and the final discharge locations for the outfalls. The Division's Winston-Salem Regional
Office will be sending you an inspection report detailing the issues from the site visit. You will need
to evaluate these issues and provide the Division with information to better characterize the drainage
and discharge points at your facility. With these issues in mind, the Division feels that your current
representative outfall designation may be inadequate to characterize the discharges from your facility.
With this permit issuance we are requesting that you begin monitoring at all outfalls in accordance
with the analytical and qualitative monitoring requirements of the permit. Once your evaluation is
complete and you have completed one year of monitoring you can request representative outfall status
from our Division.

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 (N0I) 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.

structural and nonstructural measures. The Stormwater Management Strategy, at a
minimum, shall incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to rainfall and run-on flows. Wherever practical, the
permittee shall prevent exposure of all storage areas, material handling operations,
and manufacturing or fueling operations. In areas where elimination of exposure is
not practical, this review shall document the feasibility of diverting the stormwater
run-on away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section 313
of Title III of the Superfund Amendments and Reauthorization Act (SARA) water
priority chemicals; and storage in any amount of hazardous substancesin 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
Part li Page 2 of 12

Permit No. NCS000346
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.
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 11 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 1Z

Permit No. NCS000346
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 annual basis. The annual update
shall include:
(a) an updated list of significant spills or leaks of pollutants for the previous three
(3) years, or the notation that no spills have occurred (element of the Site
Overview);
(b) a written re -certification that the stormwater outfalls have been evaluated for
the presence of non-stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on -site stormwater
BMPs (BMP Summary element of the Stormwater Management Strategy).
(d) a review and comparison of sample analytical data to benchmark values (if
applicable) over the past year, including a discussion about Tiered Response
status. The permittee shall use the Division's Annual Summary Data
Monitoring Report (DMR) form, available from the Stormwater Permitting
Program's website (See: https:/fdeg.nc.g_ov/aboutt/divisions./energy-mineral-
land-resources/npdes-stormwater-individuall.
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 I11, 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.

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 permittee
obtains approval from the local DEMLR Regional Engineer. See Definitions.

1 Measurement Frequency: Twice per year (unless other provisions of this permit prompt monthly
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.
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"
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
Part 11 Page 5 of 12

Permit No. NCS000346
of benchmark comparison and Tiered response actions, the permittee shall use the
analytical results from the first sample with valid results within the monitoring period.

Footnotes:
1 Maintain semi-annual monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded. The permittee must submit an application for renewal of coverage
before the submittal deadline (180 days before expiration) to be considered for renewed coverage
under the permit The permittee must continue analytical monitoring throughout the permit
renewal process, even if a renewal permit is not issued until after expiration of this permit
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "No Flow" or "No Discharge" within 30 days of the end of the sampling period.
3 Monitoring periods remain consistent through the permit term and through the renewal process.
Failure to monitor semi-annually per permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified time period. "No discharge" from an
outfall during a monitoring period does not constitute failure to monitor, as long as it is
properly recorded and reported.
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 (SMPs) 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 it Page 6 of 12

Permit No. NCS000346
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 parameter separately trigger a tiered response.
Tier Two
If: The first valid sampling results from two consecutive monitoring periods (omitting periods with no
discharge) are above the benchmark values, or outside of the benchmark range, for any specific parameter at
a specific discharge outfall;
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow" to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, exercise the
option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional
Engineer may direct the response actions on the part of the permittee as provided in Tier Three,
including reduced or additional sampling parameters or frequency.
S. Maintain a record of the Tier Two response in the 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.

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 gauge 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 I1
Section B.
Monitoring results shall be compared to the benchmark values in Table 5. The benchmark
values in Table 5 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 permttee to increase monitoring, increase management actions, increase record
keeping, and/or install stormwater Best Management Practices (BMPs) in response to a
tiered program. See description of tiers and required response in Part 11 Section B.

SECTION D: 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.

(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.
itative Monitori
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.
