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 III, Standard
Conditions, Section E, paragraph 3 of this permit. The SPPP shall include, at a minimum,
the following items:
1. Site Overview. The Site Overview shall provide a description of the physical facility
and the potential pollutant sources that may be expected to contribute to
contamination of stormwater discharges. The Site Overview shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters; the name of the receiving waters to which the stormwater outfalls
discharge, or if the discharge is to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the points of stormwater discharge associated with industrial
activity. The general location map (or alternatively the site map) shall identify
whether any receiving waters are impaired (on the state's 303(d) list of impaired
waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants that
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary;
the stormwater discharge outfalls; all on -site and adjacent surface waters and
wetlands; industrial activity areas (including storage of materials, disposal areas,
process areas, loading and unloading areas, and haul roads); site topography and
finished grade; all drainage features and structures; drainage area boundaries and
total contributing area for each outfall; direction of flow in each drainage area;
industrial activities occurring in each drainage area; buildings; stormwater Best
Management Practices (BMPs); and impervious surfaces. The site map must
indicate the percentage of each drainage area that is impervious, and the site map
must include a graphic scale indication and north arrow.
(d) A list of significant spills or leaks of pollutants during the previous three (3) years
and any corrective actions taken to mitigate spill impacts.
Part 11 Page 1 of 15

M
Permit No. NCS000076
(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 amoun 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.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) 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 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.
PartII Page 2 of 1 S

Permit No. NCS000076
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 Quly 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 lI 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
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.
Part 11 Page 3 of 15

Permit No. NCS000076
Responsibilities for all components of the SPPP shall be documented and position
assignments provided.
8. SPPP Amendment and Annual Update. The permittee shall amend the SPPP
whenever there is a change in design, construction, operation, site drainage,
maintenance, or configuration of the physical features which may have a significant
effect on the potential for the discharge of pollutants to surface waters. All aspects of
the SPPP shall be reviewed and updated on an annual basis_ The annual update
shall include:
(a) an updated list of significant spills or leaks of pollutants for the previous three
(3) years, or the notation that no spills have occurred (element of the Site
Overview);
(b) a written re -certification that the stormwater outfalls have been evaluated 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 ofsample analytical data to benchmark values (if
applicable) over the past year, including a discussion about Tiered Response
status. The permittee shall use the Division's Annual Summary Data
Monitoring Report (DMR) form, available from the Stormwater Permitting
Program's website (See'Monitoring Forms' here:
http: //deg.nc.gov/about/divisions/energy-mineral-land-resources/energy
mineral-land-permitsf stormwater-permits/npdes-industrial-sw).
The Director may notify the permittee when the SPPP does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee
shall submit a time schedule to the Director for modifying the SPPP to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part HI, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
9. SPPP Implementation. The permittee shall implement the Stormwater Pollution
Prevention Plan and all appropriate BMPs consistent with the provisions of this permit,
in order to control contaminants entering surface waters via stormwater.
Implementation of the SPPP shall include documentation of all monitoring,
measurements, inspections, maintenance activities, and training provided to
employees, including the log of the sampling data and of actions taken to implement
BMPs associated with the industrial activities, including vehicle maintenance activities.
Such documentation shall be kept on -site for a period of five (S) years and made
available to the Director or the Director's authorized representative immediately upon
request.
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table I.
All analytical monitoring shall be performed during a measureable storm event at each
Part II Page 4 of 15

Permit No. NCS000076 -
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 1I1, Section E). However, for purposes
Part 11 Page 5 of 15

Permit No. NCS000076
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.

1 Maintain semi-annual monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded. The permittee must submit an application for renewal of coverage
before the submittal deadline (180 days before expiration) to be considered for renewed coverage
under the permit The permittee must continue analytical monitoring throughout the permit
renewal process, even if a renewal permit is not issued until after expiration of this permit
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "No Flow" or "No Discharge" within 30 days of the end of the sampling period.
Failure to monitor semi-annually per permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified time period. "No discharge" from an
outfall during a monitoring period does not constitute failure to monitor, as long as it is
properly recorded and reported.
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.
er: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.'Ivo
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;
Part 11 Page 7 of 15

Permit No. NCS000076
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 out€all 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 DEM LR 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.
If The valid sampling results required for the permit monitoring periods exceed the benchmark value, or
are outside the benchmark range, for any specific parameter at any specific outfall on four occasions, the
permittee shall notify the DEMLR Regional Engineer in writing within 30 days of receipt of the fourth
analvtical results:
Then: The Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring and reporting frequency for
some or all of the parameters herein;
• require sampling of additional or substitute parameters;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize impacts on
receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion;
• require the permittee to continue Tier Three obligations through the permit renewal process.
This site discharges to impaired waters experiencing problems with mercury. If a Total
Maximum Daily Load (TMDL) is approved for this segment of Spring Branch, the permittee
may be required to monitor for the pollutant(s) of concern in the future and submit results
to the Division. The Division will consider the monitoring results in determining whether
additional BMPs are needed to control the pollutant(s) of concern to the maximum extent
practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a
timetable for incorporation of those BMPs into the Stormwater Pollution Prevention Plan.
SECTION C: QUALITATIVE MONITORING 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.
PartII Page 8 of 15

Permit No. NCS000076
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed semi-annually as
specified in Table 4, and during required analytical monitoring events (unless the permittee
is required to perform further qualitative monitoring per the Qualitative Monitoring
Response, below). Inability to 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.

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.

Q'ual a ve It p
itati Monitorin a odse _ A
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 D: 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 5. 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).

between outfalls prevents collecting all samples within the first 30 minutes, sampling shall be begun within
the first 30 minutes, and shall continue until completed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) that discharges
stormwater runoff from area(s) where vehicle maintenance activities occur, unless representative outfall
status (ROS) has been granted. A copy of the letter granting ROS shall be kept on site.
4 For each sampled measureable storm event the total precipitation must be recorded. An on -site rain
gauge is required. Where isolated sites are unmanned for extended periods of time, a local rain guage may
be substituted for an on -site reading.
Failure to monitor semi-annually per permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified time period, as provided in Part lI
Section B.
Monitoring results shall be compared to the benchmark values in Table 6. The benchmark
values in Table 6 are not permit limits but should be used as guidelines for the permittee's
Stormwater Pollution Prevention Plan (SPPP). Exceedances of benchmark values require
the permittee to increase monitoring, increase management actions, increase record
keeping, and/or install stormwater Best Management Practices (BMPs), as provided in Part
11 Section B.

Subject: RE: NPDES Stormwater Permit NC5000076
Hi Julie — please see comments/questions below regarding the revised SW permit:
The first question I mentioned to you on the phone earlier last week —the cover letter with changes states that
Outfalls 1 and 2 will no longer require analytical monitoring for all parameters. However, it is not listed in the
new permit.
In the current permit, it is noted on page 7 of 10 (Part II Section B) in the table and in footnote #3.
To be clear, analytical monitoring is only required for Outfalls, 3, 4, 5, and 8 (which is represented by 3) and
qualitative monitoring is still required for all outfalls (Outfalls 1, 2, 3, 4, 5, & 8) — correct?
You are correct. It is our current practice to use standard language in our permits as much as possible. Rather
than revise your permit to reflect the Representative Outfall Status, we recommend you keep a copy of the original ROS
approval letter with the permit. I've also reiterated that approval in the attached cover letter.
2. Are Biological Integrity/D.O. no longer an issue?

Page 8 of 15 — Part If Section B: Analytical Monitoring Requirements — shows mercury instead of Biological
Integrity /D.O. on the current permit — we just want to verify this is correct.
You are correct. I'm not certain why Biological Integrity/DO was included on your previous permit as it appears
this particular stream was never actually listed as impaired. My best guess is that other bodies of water
downstream of this receiving stream were impaired for DO, and the permit writer opted to include that
information.
3. Can you clarify the number of years of record retention for DMR & eDMR reports?
The new section for eDMRs shows 3 year retention for DMRs/eDMRs on page 14 of 15 - Section E: Special
Conditions, 4. Records Retention
However, the DMRs are still listed in the following two sections with a 5 year retention:
Page 4 of 15 — Part II Section A: SPPP, 9. SPPP Implementation — monitoring & measurements
Page 7 of 9 — Part III Section D: Monitoring & Records -- 5. Records Retention — DMR reports
The number of years required for record retention will change on the date you start participating in electronic
reporting of DMR data. As I understand it, until you begin electronic reporting, the minimum retention time for DMRs is
5 years. After you begin electronic reporting, the minimum retention time for DMRs is 3 years (this is the federal
requirement). All other records that don't get reported electronically will have a minimum retention time of 5
years. Having said that, I'd suggest you keep all your records for 5 years as it might make it easier to summarize the
previous 5 years of data for purposes of renewing during your permit next cycle. I'm not sure if/when we will phase out
the 5-year retention requirement all together, but for now, we are kinda stuck with this staggered schedule.
4. Sampling periods
For the current permit, we are in the May 1— Oct 31 sampling period. The new permit is supposed to begin on
Sep 1 with the first sampling period as Sep 1— Dec 31.
If the start date of the new permit remains as Sept 1, our plan is to submit a final Stormwater report for the
current permit on Aug 31. is that OK? Yes, that is fine.
5. Page 3 of 4 - Part IV #24 —the numbering starts with 'b' instead of 'a'. Thank you. I made this correction.
Feel free to call if questions — thanks!

Introduction
The Coming Incorporated facility in Wilmington has two (3) NPDES outfalls for non -
contact wastewater and stormwater, four (4) existing NPDES outfalls for stormwater only, and
eight (8) stormwater outfalls serving areas exempt from NPDES permitting. Attachment A contains
a table listing the estimated total drainage area acreage for the outfalls discussed in the next sections.
Outfall 001 SCC currently services a constructed stormwater pond (Pond 5), however, future
construction of a cooling tower system is listed in permit NC0003794, but is not currently constructed.
NPDES Permitted Outfalls
Outfalls 001, 002 and 001 SCC
NPDES Permit No. NC0003794 covers wastewater discharges from the facility via NPDES
Outfalls 001 and 002 (see Drawing labeled "Overall Sheet"). Outfalls 001 and 002
also discharge stormwater runoff from portions of the facility where chemical storage, loading
and unloading occur. Outtall 001 also receives stormwater runoff from a portion of the parking
area labeled Drainage Area 14. This drainage area is considered to be an exempt area since
it is only a parking lot (see Drawing Sheet labeled "Quad 3"). Outfall 001 has a
total drainage area of 2.24 acres. This total does not include the exempt Drainage Area 14.
Outfall 002 has a total drainage are of 9.78 acres with 6.81 acres being impervious.
Outfall 001 SCC has a total drainage area of approximately 30.35 acres, with 4.56 being impervious.
0utfalls 003, 004, 005, & 008
. Drainage Area 3 contains manufacturing assets not currently in use. The property is bounded
on the north, south and east largely by the property lines. See Drawing Sheet labeled "Quad 1"
and "Quad 4'). The total drainage area is 6.81 acres with 5.50 acres being impervious. Drainage
Area 3 discharges through Outfall 003 via a stormwater retention pond constructed in 1998.
Drainage Area 4 receives stormwater drainage from a portion of the Manufacturing Building
roof (see Drawing Sheet labeled "Quad 4"). All 2.12 acres of Drainage Area
4 are impervious. Drainage Area 4 discharges through Outfall 004. Also, exempt Drainage
Area 5D discharges through Outfall 004. Drainage Area 5D is 0.64 acres of impervious surface.
Drainage Areas 5A and 5B discharge to a stormwater retention pond located prior to Outfall
005. The retention pond was constructed in 1996. Drainage Area 5A contains 2.26 total acres
including 0.71 impervious acres. Drainage Area 5B is 6.14 acres with 4.53 acres impervious.
Two exempt drainage areas discharge through Outfall 005. Exempt Drainage Area 5C is
comprised of a manicured front lawn, with 2.21 total acres and 0.33 acres impervious. Exempt
Drainage Area 5D receives stormwater drainage from an administrative office building roof
(_64 acres impervious).
Drainage Area 16 discharges to a stormwater pond constructed in 2001. See Drawing
Sheet labeled "Quad 4". The drainage area consist of 6.81 acres, with 5.50 being impervious.
The -drainage area consists of manufacturing support equipment, pollution abatement equipment
and cooling towers.
Outfalls Exempt from NPDES Permitting
Eight (8) outfalls are identified on the storm drain piping drawings as "Exempt
Outfalls (EO)". These outfalls receive water from areas containing no industrial activity and no
• potential for stormwater contamination; therefore, these outfalls and corresponding drainage
area are exempt under NPDES regulations.

. Drainage Areas Not Being Discharged Through Outfalls
The remainder of the Coming Incorporated property, Drainage Area 6 and Drainage Area 9,
is completely pervious with no direct discharge points from the site. Drainage Area 6 is 0.49
acres and Drainage Area 9 is 10.22 acres.
Site Drainage Controls
The Wilmington plant system design standard requires storm drain systems to function during a
50-year storm event. The three (5) existing stormwater retention ponds meet the requirements of
NCDWQ State Stormwater Management Systems permit program.
All secondary containment systems located at the facility have been upgraded to retain the
capacity of the largest vessel plus a 24-hour/25-year storm event (defined as 8 inches of rainfall
for the Wilmington area). The Stormwater Pollution Prevention Plan (SP3) includes keyed lockouts
of the drain systems. The Area SP3 team identified "appropriate testing" and record keeping
provisions during Best Management Practices (BMP) development. Collected stormwater from all
secondary containment systems is evaluated prior to making a determination to discharge any
collected stormwater to the outfalls. There is an alternate system available for the discharge of
contaminated stormwater. Collected stormwater can be redirected, if required due to contamination,
to the Pollution Abatement Process for pretreatment prior to discharge to the City of Wilmington WWTP.
I*

• Best Management Practices
The Corning Incorporated facility in Wilmington relies on BMP's as well as engineered
structures to control stormwater and stormwater contamination. Following is a list of
some of the BMP's practiced at this facility.
1) Cooling tower chemicals stored in secondary containment
2) Diesel Fuel stored in secondary containment
3) Monthly testing of high level alarms in the sanitary lift stations
4) Raw materials are dispensed and waste materials are accumulated in an
enclosed building with diking and a floor sump
5) Waste drums are stored under cover in a sloped and diked area
6) Pollution abatement equipment is contained is secondary containment
• 7) Bulk raw materials are contained in secondary containment dikes
8) Stormwater accumulation in secondary containment dikes must be evaluated
before pumping to the outfall system. Water that fails criteria is sent to the
neutralization system and eventually to the POTW system.

Dear Permittee:
Division of Water Quality
Charles Wakild, PE
Director
September 4, 2012
Subject: NPDES Stormwater Permit Coverage Renewal
Wilmington Processing Plant
Permit Number NCS000076
New Hanover County
Dee Freeman
Secretary
Your facility is currently covered for stormwater discharge under NPDES Permit NCS000076. This permit
expires on 4/30/2013. To assure consideration for continued coverage under your individual permit, you
must apply to the Division of Water Quality (DWQ} for renewal of your permit. Enclosed you will find an
individual permit Renewal Application Form, Supplemental Information request, and Stormwater Pollution
Prevention Plan Certification for your facility.
Filing the application form along with the requested supplemental information will constitute your
application for renewal of this permit. Until your permit renewal is completed and you receive a new permit,
please continue to comply with all conditions and monitoring requirements in your expired NPDES
stormwater permit_
The application and supplement must be completed and returned to DWQ by November 1. 2012. Failure to
request renewal within this time period will result in delay of your permit renewal and may result in a civil
assessment. Discharge of stormwater from your facility without coverage under a valid stormwater NPDES
permit would constitute a violation of NCGS 143-215.1 and could result in assessments of civil penalties of up
to $25,000 per day.
If you have any questions regarding permit renewal procedures please contact Brian Lowther of the
Stormwater Permitting Unit at (919)-807-6368 or [e-mail].
Sincerely,
Bradley Bennett, Supervisor
