SECTION A: FINAL LIMITATIONS AND CONTROLS FOR STORMWATER DISCHARGES
During the period beginning on the effective date of the permit and lasting until expiration, the
Permiittee is authorized to discharge stormwater associated with industrial activity. Such
discharges shall be controlled, limited and monitored as specified below.
1. 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 H, Standard
Conditions, Section E.8. of -this perrnit. The Plan shall include, at a minimum, the following
items:
a_ Site Plan. The site plan shall provide a description of the physical facility and the potential
pollutant sources which may be expected to contribute to contamination of stormwater
discharges. The site plan shall contain the following:
(1) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters, the name of the receiving water(s) to which the stormwater outfall(s)
discharges, or if the discharge is to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters: and accurate latitude
and longitude of the point(s) of discharge.
(2) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(3) A site map drawn to scale with the distance legend indicating location of industrial
activities (including storage of materials, disposal areas, process areas and loading
and unloading areas), drainage structures, drainage areas for each outfall and

prevent materials exposure to stormwater. In areas where elimination of exposure
is not practicable, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(2) A schedule to provide secondary containment for bulk storage of liquid materials,
storage of Section 313 of Title lII of the Superfund Amendments and
Reauthorization Act (SARA) water priority chemicals, or storage of hazardous
materials to prevent leaks and spills from contaminating stormwater runoff. If the
secondary containment devices are connected directly to stormwater conveyance
systems, the connection shall be controlled by manually activated valves or other
similar devices [which shall be secured with a locking mechanism] and any
stormwater that accumulates in the containment area shall be at a minimum visually
observed for color, foam, and visible sheens, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. 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.
(3) A narrative description shall be provided of Best Management Practices (BMPs) to
be considered such as, but not limited to, oil and grease separation, debris control,
vegetative filter strips, infiltration and stormwater detention or retention, where
necessary. The need for structural BMPs shall be based on the assessment of

2. Minimum Monitoring and Reporting Requirements
Minimum monitoring and reporting requirements are as follows unless otherwise approved in
writing by the Director of the Division of Environmental Management.
a. If a facility has multiple discharge locations with substantially identical stormwater
discharges that are required to be sampled, the permittee may petition the Director for
representative outfall status. If it is established that the stormwater discharges are
substantially identical and the permittee is granted representative outfall status, then
sampling requirements may be performed at a reduced number of outfalls.
b. Visual monitoring for color, odor, solids, foam, outfall staining, visible sheens and dry
weather flow shall be performed at all stormwater discharge outfall Iocations. All visual
monitoring shall be documented and records maintained with the Stormwater Pollution
Prevention Plan. The initial visual monitoring event shall be performed simultaneously
with the fast analytical monitoring event and documentation of only this initial visual
monitoring event shall be submitted along with the required analytical monitoring submittal.
For purposes of the stormwater sampling required in this permit, all samples shall be
collected from a discharge resulting from a representative storm event (See Part 11,
Standard Conditions, Section A). Failure to monitor storm events in accordance with the
specified frequency shall constitute a violation of this permit. If the stormwater runoff is
controlled by a detention pond, the following sampling requirements shall apply:
(1) If the detention pond detains the runoff generated by one inch of rainfall for 24
hours, visual observations for color, foam, outfall staining, visible sheens, and dry
weather flow are required, but analytical sampling shall not be required.
(2) If the detention pond discharges only in response to a storm event exceeding a 25-
year, 24-hour storm (See Part II, Standard Conditions, Section A), the pond shall
be considered a non -discharging stormwater control system and not subject to
NPDES requirements, unless the discharge causes a violation of water quality
standards.
d. Samples analyzed in accordance with the terms of this permit shall be submitted on forms
provided by the Director no later than January 31 for the previous year in which sampling
was required to be performed.
e. Analytical results from sampling during the final year of the permit term shall be submitted
with the permit renewal application.
This permit regulates stormwater discharges. Non-stormwater discharges which shall be
allowed in the stormwater conveyance system are:
(1) All other discharges -that are authorized by a non-stormwater NPDES permit.
(2) Uncontaminated groundwater, foundation drains, air -conditioner condensate
without added chemicals, springs, discharges of uncontaminated potable water,
waterline and fire hydrant flushings, water from footing drains, flows from riparian
habitats and wetlands.
(3) Discharges resulting from fire -fighting.
Page 7

Permit No. NCS000156
If the storm event monitored and reported in accordance with this permit coincides with a
non-stormwater discharge, the pernuttee shall separately monitor and report all parameters
as required under the non-stormwater discharge permit and provide this information with
the stormwater discharge monitoring report.

been necessary to halt or reduce the permitted activity in order to maintain
compliance with the condition of this permit
a. Definitions
(1) "Bypass" means the known diversion of stormwater from any portion of a
stormwa,ter control facility including the collection system, which is not a
designed or established or operating mode for the facility.
(2) "Severe property damage" means substantial physical damage to property,
damage to the control facilities which causes them to become inoperable, or
substantial and permanent loss of natural resources which can reasonably be
expected to occur in the absence of a bypass. Severe property damage does
not mean economic loss caused by delays in production.
b. Bypass Not Exceeding Limitations.
The permittee may allow any bypass to occur which does not cause limitations to be
exceeded, but only if it also is for essential maintenance to assure efficient
operation. These bypasses are not subject to the provisions of Paragraphs c. and d.
of this section.
c. Notice
p) Anticipated bypass. If the permittee knows in advance of the need for a
bypass, it shall submit prior notice, if possible at least ten days before the
date of the bypass; including an evaluation of the anticipated quality and
affect of the bypass.

(2) Unanticipated bypass. The permittee shall submit notice within 24 hours of
an unanticipated bypass as required in Part II, E. 5. of this permit. (24-
hour notice).
d . Prohibition of Bypass
Bypass is prohibited and the Director may take enforcement action against a
permittee for bypass, unless:
(1) Bypass was unavoidable to prevent loss of life. personal injury or severe
property damage;
(2) There were no feasible alternatives to the bypass. such as the use of
auxiliary control facilities, retention of stormwater or maintenance during
normal periods of equipment downtime or dry weather. This condition is
not satisfied if adequate backup controls should have been installed in the
exercise of reasonable engineering judgment to prevent a bypass which
occurred during normal periods of equipment downtime or preventive
maintenance; and
(3) The permittee submitted notices as required under Paragraph c. of this
section.
The Director may approve an anticipated bypass, after considering its adverse
effects, if the Director determines that it will meet the three conditions listed above
in Paragraph d. of this section.
4. upsits
a. Definition
"Upset " means an exceptional incident in which there is unintentional and
temporary noncompliance with technology based permit effluent limitations

designed treatment or control facilities, inadequate treatment or control facilities,
lack of preventive maintenance, or careless or improper operation.
b. Effect of an Upset.
An upset constitutes an affirmative defense to an action brought for noncompliance
with technology based permit effluent limitations if the requirements of paragraph c.
of this condition are met No determination made during administrative review of
claims that noncompliance was caused by upset, and before an action for
noncompliance, is final administrative action subject to judicial review.
C. Conditions Necessary for a Demonstration of Upset

Dear Ms. King:
On April 1, 1996 I received your fax dealing with the recent changes in stormwater permit
sampling policy. The following changes have been made of all of North Carolina's stormwater
permits.
The April through November window for sampling has been lifted, meaning that
stormwater samples may now be taken year round. The definition of a Representative Storm Event
has also changed, and is as follows:
"A storm event that measures greater than 0.1 inches of rainfall and that is preceded by at
least 72 hours during which no storm event measuring greater than 0.1 inches has occurred.
A single storm event may contain intervals of 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."
In addition to these changes all of the permittees who were required to take composite
samples to monitor their stormwater discharges are now allowed to take grab samples in their
place. These changes are currently in effect, and will appear in a newsletter to permit holders in the
near future.
If you have questions concerning this matter, please contact me (919 / 733-5083 ext. 548).

Dear Permittee:
Your facility is currently covered for stormwater discharge under NPDES Permit NCS000156_ This permit expires
on December 31, 1999. In order to assure your continued coverage under your permit, you must apply to the
Division of Water Quality (DWQ) for renewal of your permit. To make this renewal process easier, we are
informing you in advance that your permit will be expiring. Enclosed you will find an individual permit renewal
application form, supplemental information request, and Stormwater Pollution Prevention Plan certification. Filing
the application form along with the requested supplimental information will constitute your application for renewal
of your permit. The application form must be completed and returned along with all requested information by July
19, 1999 in order to constitute a timely renewal filing.
Recent legislation modified the fee structure for DWQ permits. Renewal fees have been eliminated and annual fees
have been changed. The new annual fee for your permit is now $715.00 (you will be invoiced later this year for
your annual fee.) A copy of the new fee schedule is enclosed in this package.
Failure to request renewal by July 19, 1999 may result in a civil assessment of at least $250.00. Larger penalties
may be assessed depending on the delinquency of the request. 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 $10,000 per day.
If you have any questions regarding the permit renewal procedures please contact Tony Evans of the Stormwater

4.0 BEST MAINAGENIENT PRACTICES
Best Management Practices (BMPs) are practices, activities or physical structures that have a
primary goal of reducing the aniount of pollution in storm water discharges. This section of
the SWP3 discusses BMPs that have been identified by the pollution prevention team. A brief
summary of these BMPs are also presented in Worksheet #5 (refer to APPENDIX B)_
4.1 Good Housekeeping
The purpose of good housekeeping practices is to maintain a clean and orderly work
environment. These good housekeeping practices that have been identified by the
pollution prevention team are listed below:
Store chemicals, waste oil, and material containing potential pollutants in a neat
and orderly fashion - out of contact with storm water (under cover when
possible and on wooden pallets);
• Maintain up-to-date material inventories;
• Maintain clean floors and outdoor concrete surfaces by weekly sweeping;
• Minimize accumulation of dust, waste material (e.g., old drums, discarded
material/product bags, used pallets, used machinery parts) and waste oil by
scheduling frequent pickups;
• Train employees about good housekeeping practices.
4.2 Preventive Maintenance
Preventive maintenance inspections should be conducted to discover leaks and faulty
equipment before raw materials. intermediate materials, waste materials, or products
can impact the storm water runoff. The preventive maintenance activities that have
been identified by the pollution prevention team are listed below:
• Periodic inspections of the area around the bulk storage tanks;
• Periodic inspections of any chemical material handling areas and
loading/unloading areas to identify and clean-up any chemical spills/leaks:
Periodic inspections of all secondary containment/diking structures to
identify/repair any significant cracks (including all oil storage areas as outlined
in the Spill Prevention Control and Countermeasure (SPCC) plan and
documented in the inspection reports in APPENDIX B of the SPCC).
4.3 Visual inspection
On a semi-annual basis, plant personnel will inspect the facility for potential sources of
storm water pollution (e.g., leaks, erosion, faulty equipment, waste materials). Results.
of the inspection should be recorded on the Inspection Record Sheet (see APPENDIX
I) along with the name of the person conducting the inspection and the date of the
d

inspection. Wright's storm water permit requires that inspection records be kept until
at least one year after permit coverage expires (current permit expiration 8/31/99).
4.4 Spill Prevention and Response
The spill prevention and response activities that have been identified by the pollution
prevention team are listed below:
• Immediately clean up any spill around the chemical handling and processing
areas and along the transportation routes;
• Perform daily visual inspections of areas wit!. a high potential for chemical leaks
or spills (e.g_, areas near chemical storage, handling and usage);
• Maintain a readily available supply of absorbent materials at various locations
on -site to soak up any leaks/spills of liquids;
• Train employees to report any and all spills immediately to Ms. Shawn King or
other SWP3 team members to insure timely spill clean up and notification of the
appropriate authorities if necessary (e.g., National Response Committee (NRC),
and state and local emergency response/planning committees (SERC/LEPC)).
4.5 Sediment and Erosion Control
Wright has already taken many measures for sediment and erosion control. Areas
involved in construction will be regraded and reseeded as required to prevent erosion of
soil.
4.6 Management of Storm Water Runoff
The facility's storm water runoff is well controlled and directed towards discharge
outfalls. In the -near future Wright plans to build curbing to direct rainfall
accumulations away from processing areas-

5.0 PLAN IMPLEMENTATION
This section of the SWP3 presents the schedule for implementing the BMPs developed by the
pollution prevention team and an outline of the topics that are covered in the employee training
program.
5.1 implementation Schedule
An implementation schedule for the BMPs selected by the pollution prevention team is
presented in Worksheet #b - APPENDIX B. The SWP3 members at Wright are
responsible for implementing all of the BMPs.
5.2 Employee Training Program
The goal of the employee training program is to teach personnel, at all levels of
responsibility, the components and goals of the storm water pollution prevention plan_
A brief discussion of how the training program will be conducted and an outline of the
topics to be covered during the training program is presented below.
On an annual basis, Wright will conduct an employee training program on storm water
pollution prevention. It is suggested that this annual training take place to coincide with
Wright's OSHA Hazard Communication Program training. The SWP3 training will
focus on good housekeeping, spill prevention and response, and materials handling and
storage as detailed below.
Good Housekeeping
• Review basic cleanup procedures (e.g., sweeping, trash/waste removal) and the
location of all areas where these procedures should be followed.
• Review proper disposal locations (e.g., waste containers, waste
satellite/accumulation points) and handling/covering of stored hazardous
materials.
• Post signs in materials handling areas to remind personnel of good housekeeping
procedures and keep brooms/sweeps available in these areas.
S ;II Prevention and Res onse
• Inform employees of potential spill locations and immediate drainage routes
(e.g., spills inside the warehouse may drain to the outside storm water ditch on
the east side if not cleaned up immediately).
• Review spill clean --up procedures (e.g., removal and disposal of spilled solid
chemicals, use of absorbent materials for liquid spills).
10

• Clearly label Iocations of spill clean-up equipment and post names of individuals
to contact in the event of any spills/leaks.
Material Handline and Storage
• Ensure that employees are aware of which materials are hazardous and where
such materials are stored. Inform employees where to find specific MSDS and
the importance, relevance and use of this information.
• Discuss procedures for material handling (e.g., cover, label, store on pallets,
etc.). Also, notify employees that any chemical spills during handling and
shipping must be properly cleaned and reported immediately.

Reference: Storm Water Monitoring Report for 4th Quarter -1999
NPDES NCS000156
To whom it may concern:
The intent of this letter is to discuss the storm water monitoring results from December 6, 1999
(4th Quarter). After the 4th quarter sampling analytical report was submitted by Oxford
Laboratories, Inc. (Oxford).to Wright'Cbrporatioz-(W " ) on January 3, 2000, it was noted that
several parameters ' er than normal os at water outfall
Dowicil storm watoutfall
location. Oxford was in—tm—eak—felyt an as ed to examine the possibility of a lab mistake
during analytical procedures or calculations. In addition, Wright requested the storm water
sample bottles from Oxford. Oxford investigated and then verified the sample results were
accurate. Wright re -tested several parameters in the on -site laboratory and also validated the
results. From this point forward Wright began an investigation of the Dowicil storm water outfall
area.
About the same tune, Wright was also investigating a high result in the NPDES discharge outfall
Part of this investigation included sampling the process cooling towers (non -contact) that are
permitted to discharge through the NPDES outfall. On January 18, 2000 five cooling tower
samples were sent to Oxford to determine the BOD and COD concentrations. The results, faxed
to Wright on January 26, 2000, indicated that Cooling Tower No. 1 (CT1) had high BOD and
COD concentrations. Wright immediately performed an in-depth evaluation of the CT system
Prelirninary evidence indicates the hexamine plant distillation column condensers are leaking into
the cooling water stream. During the investigation, it was also determined that the CT I
blowdown line was not operating properly. The blowdown line, which served both CT 1 and
CT2, was broken and inadvertently directing blowdowns to the Dowicil storm water outfall. The
broken blowdown line was not recognized as a non -storm water discharge due to the "natural
springs" that are inherent on WrighCs property and was only discovered due to the investigation
of CTI.

Once the high BOD/COD concentrations were discovered the blowdown system was immediately
shut down. The old blowdown line was abandoned and on January 27, 2000 a new line was
installed to the NPDES outfall system However, CT1's blowdown will not be directed to the
outfall until the leak is fixed. CT 1 is currently being blowdown to the wastewater system CT2 is
currently utilizing the new blowdown line.
Mr. Ed Beck from the North Carolina Department of Environment and Natural Resources -
Wilmington Regional Office (NCDENR-WiRO) was contacted by phone on January 28, 2000
regarding this occurrence. Mr. Beck, along with Mr. Tim Kendall, visited the site on the.same
day to inspect CT and the Dowicil storm water outfall.
Wright believes the storm water sampling result for the Dowicil outfall will show a definite
improvement now that the blowdown line has been fixed. Wright prides itself in being an
environmental steward and believes the swift corrective action taken to remedy this problem
proves such.
The 1 st quarter storm water sampling event is scheduled for mid February-2000. Please do not
hesitate to contact me if there are any questions regarding this matter. 1 can be reached at (910)

General Statute 143-215 .1 and the Memorandum of Agreement between North Carolina and the
US Environmental Protection agency dated December 6, 1983.
Please note that the Division has revised the analytical monitoring strategy for individual
stormwater permits. Based on a review of the permit monitoring data received to date, the 2
analytical monitoring measurement frequencies have been changed and cut-off concentrations
have been removed. These changes will be implemented for all second term individual ita;' 12a r
stormwater permits with analytical monitoring requirements. For those permits with analytical L ?
monitoring requirements, Part II - Monitoring, Controls, and Limitations for Permitted
Discharges has been modified to reflect the change in monitoring strategy.
The qualitative monitoring strategy remains the same as the first term of the permit.
Please note that the semi-annual qualitative monitoring is a requirement of the permit. Failure to
complete the monitoring as required is a violation of the permit and any permit noncompliance
constitutes a violation of the Clean Water Act. Reference Part III, Section A, Item 2 "Duty to
Comply", Item 9 "Penalties for Tampering " and Item 10 "Penalties for Falsification of Reports"
of your permit for further information.
If any parts, measurement frequencies or sampling requirements contained in this permit
are unacceptable to you, you have the right to an adjudicatory hearing upon written request
within thirty (30) days following receipt of this letter. This request must be in the form of a
written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed
with the Office of Administrative Hearings, Post Office Drawer 27447, Raleigh, North Carolina
27611 -7447. Unless such demand is made, this decision shall be final and binding.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation
routes and surface waters, the name of the receiving water(s) to which the
stormwater outfall(s) discharges, or if the discharge is to a municipal separate
storm sewer system, the name of the municipality and the ultimate receiving
waters; and accurate latitude and longitude of the point(s) of discharge.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(c) A site map drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials, disposal areas, process areas
and loading and unloading areas), drainage structures, drainage areas for each
outfall and activities occurring in the drainage area, building locations, existing
BMPs and impervious surfaces, and the percentage of each drainage area that is
impervious. For each outfall, a narrative description of the potential pollutants
which could be expected to be present in the stormwater discharge.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges_ The certification statement will be signed in
accordance with the requirements found in Part Ill, Standard Conditions, Section
B, Paragraph 3.
2. Storm water Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
Part 11 Page 1 of 8

Permit No. NCS000156
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations_ In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of Section 3 t3 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous substances to prevent leaks and spills from
contaminating stormwater runoff. If the secondary containment devices are
connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be
secured with a locking mechanism] and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by the material stored within the containment area. Records
documenting the individual making the observation, the description of the
accumulated stormwater and the date and time of the release shall be kept for a
period of five years.
(c) BMP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be
based on the assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, a SPCC plan may be a component of the SPRP, but may
not be sufficient to completely address the stormwater aspects of the SPRP. The common
elements of the SPCC with the SPRP may be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.

5. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel
(or team) responsible for implementing the training shall be identified.
6. Responsible Party. The Stormwater Pollution Prevention 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 he 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. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
8. Facility Inspection Program. Facilities are required to inspect all stormwater systems on
at least a semiannual schedule, once in the fall (September -November) and once in the
spring (April - .Tune). The inspection and any subsequent maintenance activities
performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control
systems, plant equipment and systems. Records of these inspections shall be
incorporated into the Stormwater Pollution Prevention Plan.
Stormwater discharge characteristic monitoring as required in Part ii of this permit shall
be performed in addition to facility inspections.
9. Implementation. The permittee shall document all monitoring, measurements,
inspections and maintenance activities and training provided to employees, including the
log of the sampling data and of activities taken to implement Bws associated with the

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.
19_ Representative Outfall Status
When it is established that the discharge of stormwater runoff from a single outfall is representative of the
discharges at multiple outfalls, the DWQ may grant representative outfall status. Representative outfall
status allows the permittee to perform analytical monitoring at a reduced number of outfalls.
20. Rinse Water Discharge
The discharge of rinse water from equipment cleaning areas associated with industrial activity. Rinse
waters from vehicle and equipment cleaning areas are process wastewaters and do not include wastewaters
utilizing any type of detergent or cleaning agent_
21. Secondary Containment
Spill containment for the contents of the single largest tank within the containment structure plus sufficient
freeboard to allow for the 25-year, 24-hour storm event.
22. Section 313 Water Priority Chemical
A chemical or chemical category which:
Is listed in 40 CFR 372.65 pursuant to Section 313 of Tide III of the Superfund Amendments and
Reauthorization Act (SARA) of 1986, also titled the Emergency Planning and Community Right -
to -Know Act of 1986:
b. Is present at or above threshold levels at a facility subject to SARA title III, Section 313 reporting
requirements; and
That meet at least one of the following criteria:
(1) Is listed in Appendix D of 40 CFR part 122 on either Table It (organic priority
pollutants), Table HI (certain metals, cyanides, and phenols) or Table IV (certain toxic
pollutants and hazardous substances);
(2) Is listed as a hazardous substance pursuant to section 31 1(b)(2)(A) of the CWA at 40
CFR 1 16.4, or
(3) Is a pollutant for which EPA has published acute or chronic water quality criteria.

23, Severe Propertv Damage
Means substantial physical damage to property, damage to the control facilities which causes them to
become inoperable, or substantial and permanent loss of natural resources which can reasonably be
expected to occur in the absence of a bypass. Severe property damage does not mean economic loss
caused by delays in production.
24. Significant Materials
Includes, but is not limited to: raw materials; fuels; materials such as solvents, detergents, and plastic
pellets; finished materials such as metallic products; raw materials used in food processing or production;
hazardous substances designated under section 101(14) of CERCLA; any chemical the facility is required to
report pursuant to section 313 of Title III of SARA; fertilizers; pesticides; and waste products such as ashes,
slag and sludge that have the potential to be released with stormwater discharges.
25. Significant Spills
Includes, but is not limited to: releases of oil or hazardous substances in excess of reportable quantities
under section 31 t of the Clean Water Act (Ref: 40 CFR 110,10 and CFR 117.21) or section 102 of
CERCLA (Ref: 40 CFR 302.4).
26. Stormwater Runoff
The flow of water which results from precipitation and which occurs immediately following rainfall or as a
result of snowmelt.
27. Stormwater Associated with Industrial Activity
The discharge from any point source which is used for collecting and conveying stormwater and which is
directly related to manufacturing, processing or raw material storage areas at an industrial site. Facilities
considered to be engaged in "industrial activities" include those activities defined in 40 CFR 122.26(b)(14).
The term does not include discharges from facilities or activities excluded from the NPDES program.
28. Stormwater Pollution Prevention Plan
A comprehensive site -specific plan which details measures and practices to reduce stormwater pollution and
is based on an evaluation of the pollution potential of the site.
29, Ten Year Design Storm
The maximum 24 hour precipitation event expected to be equated or exceeded on the average once in ten
years. Design storm information can be found in the State of North Carolina Erosion and Sediment Control
Planning and Design Manual,
30. Total Flow
The flow corresponding to the time period over which the entire storm event occurs. Total flow shall be
either; (a) measured continuously, (b) calculated based on the amount of area draining to the outfall, the
amount of built -upon (impervious) area, and the total amount of rainfall, or (c) estimated by the
measurement of flow at 20 minute intervals during the rainfall event_
31. Toxic Pollutant
Any pollutant listed as toxic under Section 307(a)(1) of the [:lean Water Act.

31 V A'Set
Means an exceptional incident in which there is unintentional and temporary noncompliance with
technology based permit effluent limitations because of factors beyond the reasonable control of the
permittee. An upset does not include noncompliance to the extent caused by operational error. improperly
designed treatment or control facilities, inadequate treatment or control facilities, lack of preventive
maintenance, or careless or improper operation.
33. Vehicle Maintenance Activity
Vehicle rehabilitation, mechanical repairs, painting, fueling, lubrication, vehicle cleaning operations, or
airport deicing operations.
34. Visible Sedimentation
Solid particulate matter, both mineral and organic, that has been or is being transported by water. air,
gravity, or ice from its site of origin which can be seen with the unaided eye.
35. 25-year, 24 hour storm event
The maximum 24-hour precipitation event expected to be equaled or exceeded, on the average, once in 25
years.
