Subject: Draft NPDES Stormwater Permit
Permit No. NCS000346
Insteel Wire Products
Surry County
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 11, 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.

Page 2
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. Nan -Polar Oil &
Grease [EPA Method 1664 (SGT-HEM)) replaces Gil & Grease/TPH. The benchmark for Non -polar Oil
& Grease using this method is 15 mg1L,. This requirement appears in all individual stormwater permits:
however, it only applies to facilities that perform onsite vehicle maintenance activities. It 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 III,
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 may be emailed to me at bradiey-0-er71 t( mdenr gs. or mailed to my attention at NC
DEMLR, Stormwater Permitting Program, 1612 Mail Service Center, Raleigh, NC 27699-1612. With this
notification the Division will solicit comment on this draft by publishing a notice in a local newspaper. Following
the 30 day public comment period, the Division will review comments and take appropriate action prior to
issuance of the final permit.
If you have any questions, please email me or call me at [phone],
Sincerely,
Bradley Bennett

RE: Insteel Wire Products; NCS000346
Dear Bradley Bennett:
NC N HD E-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 surveys where suitable habitat exists.
In the event that rare species are found within the project area, please contact the NCNHP so that we may
update our records.
The attached 'Potential Occurrences' table summarizes rare species and natural communities that have been
documented within a one -mile radius of the property boundary. The proximity of these records suggests that
these natural heritage elements may potentially be present in the project area if suitable habitat exists 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.butler ncdcr aov or 919.707.8603.
Sincerely,
NC Natural Heritage Program

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

Hi Brad,
Thanks for the detailed response. We will work on collecting the information you requested to allow for a productive
meeting. Unfortunately, our schedule is tight early in the week when you anticipate being in the office —would a call on
Thursday be okay? Otherwise we could speak the following week when you are in the office again.

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 set up 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.

• 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.).
• If there have been and facility changes please provide an updated site map.
• 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.
• 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.
• 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.
• Please provide other information that you think will be helpful in the review for renewal.
Thanks for your help!

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,
Stephanie

Central Office Review Summary:
1. Owner's Other Permits: No other permits in BIMS.
2. General Observations:
Have steel wire stored outside.
3. Impairment: Lovills Creek is on the 303(d) for exceeding the biological criteria. The parameter of interest is
ecological/biological integrity and benthos.
Lovills Creek continues to receive Fair bioclassiftcations in the reach that flows through Mount Airy. This
portion of the watershed is almost completely developed and most certainly is affected by nonpoint source
pollution. However, Proctor Silex, which discharges above the monitoring site, failed 38 percent of chronic
toxicity tests between September 1997 and October 2000. These sporadic toxicity problems could be a large
contributor to impairment as well. Proctor Silex closed in 2001 and no longer discharges to Lovills Creek. The
NPDES permit for this facility will likely be rescinded.
DWQ will continue to monitor Lovills Creek to evaluate any improvement following the closure of Proctor
Silex.. However, local actions are needed to reduce the effects of nonpoint source pollution, particularly from
stormwater runoff, and to restore habitat inthe lower portion of the watershed. In many locations, the stream
may need extensive restoration work in order to fully support aquatic life.
4. Threatened and Endangered: Based on the Natural Heritage Virtual Workroom there are no federally protected
species within two miles of the site.
5. Location: Outfall goes to a classified C stream.
6. Industrial Changes Since Previous Permit: There were no significant changes in industrial activities when the
application was submitted. The vehicle maintenance activities are maintained by an outside company and IWP
cannot track the motor oil usage. They want to no longer do Analytical Monitoring Requirements for On -Site
Vehicle Maintenance and have this section removed from the permit. However, the section is -standard for all
individual permits and analytical monitoring is only for facilities which 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. Therefore, this site still might need to monitor and must ask the outside company how much oil is being
used.
7. Analytical Monitorinjg Notes: The current permit requires monitoring once for the first three years and then four
times during the fourth year. Monitoring data was only submitted two times for two outfalls. The results were
over the current benchmarks for both TSS and COD. After taking to the permit contact, one more set of samples
were submitted. They included TSS, COD, Cd, Pb and Ni. TSS was over the current benchmark for both
outlets.
Sector F of the EPA Multi -Sector General Permit suggests monitoring for Total Aluminum (0.75 mgll) and Total
Zinc (hardness dependent). Al and Zn will be added to the renewed permit.
Monitoring for all the current parameters, TSS, COD, Cd and Pb will remain because of the lack of data.
8. Qualitative Monitoring Notes: The visual monitoring was only submitted once for each outfall. The water was
slightly brown but no other real signs of pollution. The permit requires qualitative monitoring to be done twice a
year.

Revised Permit Recommendations: Analytical Monitoring:
1. Maintain parameters TSS, COD, Cd and Pb. Add Al and Zn.
2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part II
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30 days
of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs) in a tiered program. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier 1 guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
5. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of representative
outfall status.
6. The permittee is responsible for all monitoring until the renewal permit is issued._ See Footnote I of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
S. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part II Section
A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CFR § 122.26(g), the facility may qualify
for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional information
is provided in Part I Section A.

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.

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 Ai, 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)).
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.

Stormwater Permit NCS000346
The stormwater on Insteel's property should be monitored at two
places, minimum. The drainage from one source will go to an
unnamed UT to Lovills Creek - incorrectly identified as class WS-IV
in the Draft Permit; it is class "C". The other source of
stormwater drainage will go to the Ararat River, class "C", via a
drainage ditch.
Insteel should monitor for iron and any other source of
contamination from storing their finished product outside and
exposed.
Insteel has a vehicle maintenance facility and should be required
to monitor accordingly.

Dear Mr. Blood:
The Winston-Salem Regional Office staff have reviewed your request dated February 111h for a determination
that stormwater discharge outfall (SDO) 002 be granted representative outfall status for stormwater outfalls
001, 003, and 004. Based on the information and maps provided and the site visit our office performed on
February 3, 2009, we are approving this request. In accordance with 40 CFR §122.21(g)(7), you are
authorized to sample outfall number 002 as a representative outfall. This approval is effective with the next
sampling event. We also want to remind you that the permit still requires Qualitative Monitoring be performed
at all SDOs, regardless of representative status.
Please remember that any actions you initiate in response to benchmark exceedences as directed in the tiered
response provisions of your permit must address all drainage areas represented by SDO 002, where
appropriate.
-Piease•append this letter to your Stormwater Pollution Prevention- Plan (SPPP) or permit to document that. .
representative outfall status has been approved. If changes in drainage areas, structures, processes; storage
practices, or other activities occur -,that significantly after the basis of this approval, representative outfall,status
may no longer be valid. You should either resume sampling at all SDOs, or reapply to this office for
representative outfall status based on updated information. If you have any questions or comments
concerning this letter, please contact me at (336) 771-5.000.

REPRESENTATIVE OUTFALL STATUS (ROS)
REQUEST FORM
FOR AGENCY USE ONLY
Date Received
Year
Month
Day
If a facility is required to sample multiple discharge locations with very similar stormwater discharges, the
permittee may petition the Director for Representative Outfall Status (ROS). DWQ maygrant
Representative Outfall Status if stormwater discharges from a single outfall are established as
representative of discharges from multiple outfalls. Approved ROS will reduce the number of outfalls
where anal sampling requirements apply.
If Representative Outfall Status is granted, ALL outfalls are still subject to the qualitative monitoring
requirements of the facility's permit. After ROS is granted, the facility must notify DWO in writing if any
changes to the facility or its operations take place that would affect this status. The approval letter from
DINO must be kept on -site with the facility's Stormwater Pollution Prevention Plan.
For questions, please contact the DWO Regional Office for your area (see page 3).

Representative Outfall Status Request
4) Detailed explanation about why the outfalls above should be granted Representative Status:
(Or, attach a letter or narrative to discuss this information.) For example, describe how activities and/or
materials are similar.
The facility produces welded wire products. All materials stored on the property are of
the same material type and are stored outside the facility where contact with storm water
takes place. A site location and drainage map is attached to this request form. All
outfalls, 1 through 4, receive storm water from similar sources such as: product and raw
material storage areas; roof drainage; and natural and impervious ground cover.
Results from storm water monitoring for Outfalls 1 and 2 have had similar results. _
Outfalle 3 and 4—are new thus there is no_monitoring data. A monitoring results summary
of the past three years is attached to this request form.
5) Certification:
North Carolina General Statute 143-215.6 B(i) provides that:
Any person who knowingly makes any false statement, representation, or certification in any application, record, report, plan, or other
document filed or required to be maintained under this Article or a rule implementing this Article; or who knowingly makes a false
statement of a material fact in a rulemaking proceeding or contested case under this Article; or who falsifies, tampers with, cr knowingly
renders inaccurate any recording or monitoring device or method required to be operated or maintained under this Article or rules of the
[Environmental Management] Commission implementing this Article shall be guilty of a Class 2 misdemeanor which may include a fine
not to exceed ten thousand dollars ($10,000).
I hereby request Representative Outfall Status for my NPDES Permit. I understand that ALL outfalls are still
subject to the qualitative monitoring requirements of the permit. I must notify DWQ in writing if any changes to
the facility or its operations take place after ROS is granted that may affect this status. If ROS no longer
applies, I understand I must resume analytical monitoring of all outfalls as specified in my NPDES permit.
I certify that I am familiar with the information contained in this application and that to the best of my
knowledge and belief such information is true, complete, and accurate.

Subject: Draft NPD)S Stormwater Permit
Permit No. NCS000346
Insteel Wire Products
Surry County
Dear Mr. Cockerham:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
-1. Analytical monitoring parameters, TSS, COD, Cd and Pb, have been maintained in this permit.
Additional monitoring will include Al and Zn.
2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part Il Section B. The permittee must also document the total precipitation for each event. If no discharge
occurs during the sampling period, the permittee must submit a monitoring report indicating "No Flow"
within 30 days of the end of the six-month sampling period: Additionally, samples must be taken a
minimum of 60 days apart, as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark
values require the permittee to increase monitoring, increase management actions, increase record
keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered program. If the
sampling results are above a benchmark value, or outside of the benchmark range, for any parameter at
any outfall then the facility shall follow the Tier 1 guidelines which require a facility inspection within
two weeks and implementation of a mitigation plan within two months. If during the term of this permit,
the sampling results are above the benchmark values, or outside of the benchmark range, for any specific
parameter at a specific discharge outfall two times in a row (consecutive), then the facility shall follow the
Tier 2 guidelines which require a repetition of the steps listed for Tier 1 and also immediately institute
monthly monitoring for all. parameters at every outfall where a sampling result exceeded the benchmark
value for two consecutive samples.
5. You are required to conduct all of the analytical and qualitative monitoring during representative storm
events as defined in Part II Section B. Qualitative monitoring is required at every outfall regardless of
representative outfall status.
6. In the event that this permit expires, you are responsible for all monitoring until the renewal permit is
issued. See Footnote 1 of Tables 1, 4, and 5.

7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is still required in this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical
and qualitative monitoring. This requirement appears in all Individual Stormwater permits, however it
only applies to facilities that do vehicle maintenance. If the facility begins vehicle maintenance during the
permitted timeframe then the requirements in Section ILD shall apply.
Other permit changes:
1. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II
Section A. The plan must also be updated annually to include a list of significant spills and to certify that
the outfalls do not contain non-stormwater discharges.
2. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants
in each outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of
significant spills that have occurred in the past three years and also must certify that the outfalls have
been inspected to ensure that they do not contain non-stormwater discharges. Additional information is
provided in Part II Section A.
3. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A.
More details regarding secondary containment are provided.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial
materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the
facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit
requirements. Additional information is provided in Part I Section A.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] or

Central Office Review Summary:
1. Owner's Other Permits: No other permits in BIMS.
2. General Observations:
Have steel wire stored outside.
3. hnpairment: Lovills Creek is on the 303(d) for exceeding the biological criteria. The parameter of interest is
ecological/biological integrity and benthos.
Lovills Creek continues to receive Fair bioclassifications in the reach that flows through Mount Airy. This
portion of the watershed is almost completely developed and most certainly is affected by nonpoint source
pollution. However, Proctor Silex, which discharges above the monitoring site, failed 38 percent of chronic
toxicity tests between September 1997 and October 2000. These sporadic toxicity problems could be a large
contributor to impairment as well. Proctor Silex closed in 2001 and no longer discharges to Lovills Creek. The
NPDES permit for this facility will likely be rescinded.
DWQ will continue to monitor Lovills Creek to evaluate any improvement following the closure of Proctor
Silex. However, local actions are needed to reduce the effects of nonpoint source pollution, particularly from
stormwater runoff, and to restore habitat in the lower portion of the watershed. In many locations, the stream
may need extensive restoration work in order to fully support aquatic life.
4. Threatened and Endangered: Based on the Natural Heritage Virtual Workroom there are no federally protected
species within two miles of the site.
5. Location: Outfall goes to a classified C stream.
6. Industrial Changes Since Previous Permit: There were no significant changes in industrial activities when the
application was submitted. The vehicle maintenance activities are maintained by an outside company and IWP
cannot track the motor oil usage. They want to no longer do Analytical Monitoring Requirements for On -Site
Vehicle Maintenance and have this section removed from the permit. However, the section is standard for all
individual permits and analytical monitoring is only for facilities which 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. Therefore, this site still might need to monitor and must ask the outside company how much oil is being
used.
Analytical Monitoring: The current permit requires monitoring once for the first three years and then four
times during the fourth year. Monitoring data was only submitted two times for two outfalls. The results were
over the current benchmarks for both TSS and COD. After taking to the permit contact, one more set of samples
were submitted. They included TSS, COD, Cd, Pb and Ni. TSS was over the current benchmark for both
outlets.
Sector F of the EPA Multi -Sector General Permit suggests monitoring for Total Aluminum (0.75 mg/1) and Total
Zinc (hardness dependent). Al and Zn will be added to the renewed permit.
Monitoring for all the current parameters, TSS, COD, Cd and Pb will remain because of the lack of data.
S. Qualitative Monitoring Notes: The visual monitoring was only submitted once for each outfall. The water was
slightly brown but no other real signs of pollution. The permit requires qualitative monitoring to be done twice a
year.

Revised Permit Recommendations: Analytical Monitoring:
1. Maintain parameters TSS, COD, Cd and Pb. Add Al and Zn.
2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part lI
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30 days
of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs) in a tiered program. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier 1 guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
5. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part 11 Section B. Qualitative monitoring is required regardless of representative
outfall status.
6. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part II Section
A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part IT Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part I1 Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CFR § 122.26(g), the facility may qualify
for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional information
is provided in Part I Section A,

Regional Office Staff Comments
Brian:
I performed a Compliance Evaluation Inspection on February 3, 2009. The site appeared
clean and well maintained, and no problems were noted. However, I did find two more
stormwater outfalls on the site. When I asked them why they were not listed on the site map or
in the SPPP, they said that these stormwater outfalls were constructed after the initial permit
was issued. I told them to add them to their site plan and their SPPP. They told me they would
gladly take care of it.
I concur with your recommendation to issue an Individual Stormwater Permit to Insteel Wire
Products. If 1 can be of anymore help, please contact me at [phone].

Representative Outfall Status Request
Insteel Wire Products
Surry County
Dear Mr. Blood:
The Winston-Salem Regional Office staff have reviewed your request dated February 111h for a determination
that stormwater discharge outfall (SDO) 002 be granted representative outfall status for stormwater outfalls
001, 003, and 004. Based on the information and maps provided and the site visit our office performed on
February 3, 2009, we are approving this request. In accordance with 40 CFR §122.21(g)(7), you are
authorized to sample outfall number 002 as a representative outfall. This approval is effective with the next
sampling event. We also want to remind you that.the permit still requires Qualitative Monitoring be performed
at all SDOs, regardless of representative status.
Please remember that any actions you initiate in response to benchmark exceedences as directed in the tiered
response provisions of your permit must address all drainage areas represented by SDO 002, where
appropriate.
Please append this letter to your Stormwater Pollution Prevention Plan (SPPP-) or permit to document that.
representative outfall status has been approved. If changes in drainage areas, structures, processes, storage
practices, or other activities occur that significantly alter the basis of this approval, representative outfall status
may no longer be valid. You should either resume sampling at all SDOs, or reapply to this office for
representative outfall status based on updated information. If you have any questions or comments
concerning this letter, please contact me at [phone].

Dear Mr. Cockerham:
Dee Freeman
Secretary
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
I. Analytical monitoring parameters, TSS, COD, Cd and Pb, have been maintained in this permit.
Additional monitoring will include Al and Zn.
2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part II Section B. The permittee must also document the total precipitation for each event. if no discharge
occurs during the sampling period, the permittee must submit a monitoring report indicating "No Flow"
within 30 days of the end of the six-month sampling period: Additionally, samples must be taken a
minimum of 60 days apart, as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark
values require the permittee to increase monitoring, increase management actions, increase record
keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered program. If the
sampling results are above a benchmark value, or outside of the benchmark range, for any parameter at
any outfall then the facility shall follow the Tier 1 guidelines which require a facility inspection within
two weeks and implementation of a mitigation plan within two months. If during the term of this permit,
the sampling results are above the benchmark values, or outside of the benchmark range, for any specific
parameter at a specific discharge outfall two times in a row (consecutive), then the facility shall follow the
Tier 2 guidelines which require a repetition of the steps listed for Tier 1 and also immediately institute
monthly monitoring for all parameters at every outfall where a sampling result exceeded the benchmark
value for two consecutive samples.
5. You are required to conduct all of the analytical and qualitative monitoring during representative storm
events as defined in Part I1 Section B. Qualitative monitoring is required at every outfall regardless of
representative outfall status.
6. In the event that this permit expires, you are responsible for all monitoring until the renewal permit is
issued. See Footnote 1 of Tables 1, 4, and 5.

7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is still required in this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical
and qualitative monitoring. This requirement appears in all Individual Stormwater permits, however it
only applies to facilities that do vehicle maintenance. If the facility begins vehicle maintenance during the
permitted timeframe then the requirements in Section II.D shall apply.
Other permit changes:
1. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II
Section A. The plan must also be updated annually to include a list of significant spills and to certify that
the outfalls do not contain non-stormwater discharges.
2. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants
in each outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of
significant spills that have occurred in the past three years and also must certify that the outfalls have
been inspected to ensure that they do not contain non-stormwater discharges. Additional information is
provided in Part II Section A.
3. Additional requirements for the Stormwater Management Plan have been specified in Part I1 Section A.
More details regarding secondary containment are provided.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part I1 Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial
materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the
facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit
requirements. Additional information is provided in Part I Section A.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.

Central Office Review Summary:
1. Owner's Other Permits: No other permits in BIMS.
2. General Observations:
Have steel wire stored outside.
3. Tm a� irment: Lovills Creek is on the 303(d) for exceeding the biological criteria. The parameter of interest is
ecologicallbiological integrity and benthos.
Lovills Creek continues to receive Fair bioclassifications in the reach that flows through Mount Airy. This
portion of the watershed is almost completely developed and most certainly is affected by nonpoint source
pollution. However, Proctor Silex, which discharges above the monitoring site, failed 38 percent of chronic
toxicity tests between September 1997 and October 2000. These sporadic toxicity problems could be a large
contributor to impairment as well. Proctor Silex closed in 2001 and no longer discharges to Lovills Creek. The
NPDES permit for this facility will likely be rescinded.
DWQ will continue to monitor Lovills Creek to evaluate any improvement following the closure of Proctor
Silex. However, local actions are needed to reduce the effects of nonpoint source pollution, particularly from
stormwater runoff, and to restore habitat in the lower portion of the watershed. In many locations, the stream
may need extensive restoration work in order to fully support aquatic life.
4. Threatened and Endangered: Based on the Natural Heritage Virtual Workroom there are no federally protected
species within two miles of the site.
5. Location: Outfall goes to a classified C stream.
b. Industrial Changes Since Previous Permit: There were no significant changes in industrial activities when the
application was submitted. The vehicle maintenance activities are maintained by an outside company and IWP
cannot track the motor oil usage. They want to no longer do Analytical Monitoring Requirements for On -Site
Vehicle Maintenance and have this section removed from the permit. However, the section is -standard for all
individual permits and analytical monitoring is only for facilities which 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. Therefore, this site still might need to monitor and must ask the outside company how much oil is being
used.
7. Analytical Monitoring Notes: The current permit requires monitoring once for the first three years and then four
times during the fourth year. Monitoring data was only submitted two times for two outfalls. The results were
over the current benchmarks for both TSS and COD. After taking to the permit contact, one more set of samples
were submitted. They included TSS, COD, Cd, Pb and Ni. TSS was over the current benchmark for both
outlets.
Sector F of the EPA Multi -Sector General Permit suggests monitoring for Total Aluminum (0.75 mg/1) and Total
Zinc (hardness dependent). Al and Zn will be added to the renewed permit.
Monitoring for all the current parameters, TSS, COD, Cd and Pb will remain because of the lack of data.
8. Qualitative Monitoring Notes: The visual monitoring was only submitted once for each outfall. The water was
slightly brown but no other real signs of pollution. The permit requires qualitative monitoring to be done twice a
year.

Revised Permit Recommendations: Analytical Monitoring:
1. Maintain parameters TSS, COD, Cd and Pb. Add Al and Zn.
2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part II
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30 days
of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs) in a tiered program. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier 1 guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
5. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part Il Section B. Qualitative monitoring is required regardless of representative
outfall status.
6. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
S. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part II Section
A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CFR § 122.26(g), the facility may qualify
for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional information
is provided in Part I Section A. .

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part I11, Standard
Conditions, Section E, Paragraph 3 of this general permit. The Plan shall include, at a minimum,
the following items:
Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected tdlcontribute to contamination of
stormwater discharges. The site plan shall contain t' e,following:
(a) A general location map (USGS quadfangle map or appropriately drafted
equivalent map), showing the facility,s location in relation to transportation
routes and surface waters, the name ofthe receiving water(s) to which the
/ l �` h
stormwater outfall(s) discharges', or/,if the discharge is to a municipal separate
storm sewer system, the nam�of�the municipality and the ultimate receiving
waters, and accurate latitude and longitude of the point(s) of discharge. The
general location map (or alternatively the site map) shall identify whether each
receiving water is impaired (on the state's 303(d) list of impaired waters) or is
located in a watershed for which a TMDL has been established, and what the
parameter(s) ofconcemiare.
North Carolina's 303(d) List can be found here:
http://h2o.enr.state:nC.us/tmdI/General-303d.htm#Downloads
North Carolina TMDL documents can be found here:
httn://h2o.enr.state.nc.us/tmdl/TMDL list.htm##Final TMDLs.
(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 which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: 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, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three (3) previous years and any corrective actions taken to mitigate
spill impacts.
Part II Page 3 of 10

Permit No. NCS000346
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part I11, Standard Conditions, Section
B, Paragraph 5. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following: /��
(a) Feasibility Study. A review of the technical4and�economic feasibility of changing
the methods of operations and/or storage practicesto-eliminate or reduce
exposure of materials and processes to stormwater.—Where ver practical, the
permittee shall prevent exposure of all,storage areas, material handling
operations, and manufacturing or fueling operations. In areas where elimination
of exposure is not practical, the stormwater,management plan shall document the
feasibility of diverting the stormwater runoff away from areas of potential
/
contamination. !/I it I`
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk sNor ge 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•,lti ks 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 directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices (which shall be
secured closed with a locking mechanism), and any stormwater that accumulates
in the containment area shall be at a minimum visually observed for color, foam,
outfall staining, visible sheens and dry weather flow, prior to release of the
accumulated stormwater. Accumulated stormwater shall be released if found to
be uncontaminated by the material stored within the containment area. Records
documenting the individual making the observation, the description of the
accumulated stormwater, and the date and time of the release shall be kept for a
period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
Part II Page 4 of 10

Permit No. NCS000346
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible for implementing
the SPRP shall be identified in a written list incorporated into the SPRP and signed and
dated by each individual acknowledging their responsibilities for the plan. A responsible
person shall be on -site at all times during facility operations that have the potential to
contaminate stormwater runoff through spills or exposure of materials associated with the
facility operations. The SPRP must be site stormwater specific. Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP,
but may not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping programG all,,b�e^developed. The program shall list
all stormwater control systems, stormwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity-areas,(including material storage areas,
material handling areas, disposal areas, process areas, loading and unloading areas, and
haul roads), all drainage features and structures, and existing structural BMPs. The
program shall establish schedules of inspections; -maintenance, and housekeeping
activities of stormwater control systems,�as well as facility equipment, facility areas, and
r t. �i
facility systems that present a potential fo.rstormwater exposure or stormwater pollution.
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 in writing and maintained
in the SPPP. ( /\,/
5. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill response
and cleanup, preventative maintenance activities, and for any of the facility's operations
that have the potential to contaminate stormwater runoff Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training
shall be documented by the signature of each employee trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the Stormwater
Pollution Prevention Plan shall be reviewed and updated on an annual basis. The annual
update shall include an updated list of significant spills or leaks of pollutants for the
previous three years, or the notation that no spills have occurred. The annual update shall
include re -certification that the stormwater outfalls have been evaluated for the presence
of non-stormwater discharges. Each annual update shall include a re-evaluation of the
Part II Page 5 of 10

Permit No. NCS000346
effectiveness of the BMPs listed in the BMP Summary of the Stormwater Management
Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 5) to the Director that the changes
have been made.
8. 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-annuall y.}These facility inspections
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part II B and C of this permit.
9. Implementation. The permittee shall imple e t the,Plan. Implementation of the Plan
shall include documentation of all monttonng, measurements, inspections, maintenance
activities, and training provided to employees,,including the log of the sampling data and
of actions taken to implerrient B1VIPs associated with the industrial activities, including
vehicle maintenance activities. Such documentation shall be kept on -site for a period of
five years and made available to th`eDirector or the Director's authorized representative
immediately upon request

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

Regional Office Staff Comments
Brian:
I performed a Compliance Evaluation Inspection on February 3, 2009. The site appeared
clean and well maintained, and no problems were noted. However, I did find two more
stormwater outfalls on the site. When I asked them why they were not listed on the site map or
in the SPPP, they said that these Stormwater outfalls were constructed after the initial permit
was issued. I told them to add them to their site plan and their SPPP. They told me they would
gladly take care of it.
I concur with your recommendation to issue an Individual Stormwater Permit to Insteel'Wire
Products. If I can be of anymore help, please contact me at [phone].

ANALYTICAL RESULTS
The summary of analytical results is included as Table 1. IWP would like to request for
DENR to check their files to locate any missing analytical information, as Insteel has
been through a number of personnel changes in the last few years and could not include
all required analytical results. IWP has submitted this information to the state in the past.
Additionally, the facility will submit the most recent set of analytical results to the state
upon receipt of the Iaboratory reports.

BEST MANAGEMENT PRACTICES
IWP implements Best Management Practices (BMPs), good housekeeping and
preventative maintenance. Employees are trained annually in spill prevention and
response, good housekeeping and preventative maintenance, BMPs, overall stormwater
pollution prevention goals, sampling technique and protocol.
BMPs for spill prevention and response include precautions, notifications and actions
taken to prevent spills of oil, hazardous materials, small quantity spills, and spills that
could extend off of the property. All secondary containment drains are kept locked and
closed at all times. Additionally, a spill kit including absorbent material is located in a
strategic place to aid in any small spills that may occur.

Page 3 of 3
Visual inspections of the facility are conducted on a semi-annual schedule including
inspection of all material storage and handling areas, waste generation areas, stormwater
management devices, equipment, outdoor processing areas and any areas Ahere spills
may occur.
All records pertaining to visual inspections, employee training, or analytical monitoring
are kept on -site for a minimum of five (5) years. The Stormwater Pollution Prevention
PIan is reviewed and updated annually.
SIGNIFICANT CRANGES TO INDUSTRIAL ACTIVITIES
There are currently no significant changes in industrial activities. However, the vehicle
maintenance activities are maintained by an outside company. Therefore, IWP cannot
track the motor oil usage and feels that they ae no longer subject to the Analytical
Monitoring Requirements for On -Site Vehicle Maintenance, as listed ui Section D of the
permit. IWP would like to request that this section of monitoring requirements be
removed from the new permit, since it does not apply.
