PART I
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 below:
1. The Permittee shall develop a Stormwater Pollution Prevention Plan, herein
after referred to as the Plan. 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
activities occurring in the drainage area, building locations 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.
(4) A list of significant spills or leaks of pollutants that have
occurred at the facility during the 3 previous years and any

fueling operations to 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 III of the'
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous materials to prevent leaks and
spills from contaminating atormwater 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

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 potential -of sources to contribute significant
quantities of pollutants to stormwater discharges and data
collected through monitoring of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and
measures to be taken to limit or prevent erosion associated with
the atormwater systems.
C. Spill Prevention and Response Plan. The Spill Prevention and Response
Plan shall incorporate a risk assessment of potential pollutant sources
based on a materials inventory of the facility. facility personnel (or
team) responsible for implementing the plan shall be identified in the
plan. A responsible person shall be on -site at all times during

facility operations.
d. '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.
e. 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 in the plan.
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(s) assignments provided. 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

The permittee shall at all times properly operate and maintain all
facilities and systems of treatment and control (and related
appurtenances) which are installed or used by the permittee to achieve
compliance with the conditions of this general permit. Proper operation
and maintenance also includes adequate laboratory controls and
appropriate quality assurance procedures. This provision requires the
operation of back-up or auxiliary facilities or similar systems which
are installed by a permittee only when the operation is necessary to
achieve compliance with the conditions of the general permit.
It shall not be a defense for a permittee in an enforcement action that
it would have been necessary to halt or reduce the permitted activity
in order to maintain compliance with the condition of this general'
permit.
a. Definitions
(1) "Bypass" means the known diversion of stormwater from any portion of a
stormwater 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 wean economic loss caused by delays in
production.
b'. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause
effluent 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
(1) 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 of an
unanticipated bypass as required in Part II, E. 5. of this general
permit. (24-hour notice).

Permit No. NCGO80000 -
d.' Prohibition of Bypass
(1) Bypass is prohibited and the Director may take enforcement action
against a permittee for bypass, unless:
(a) Bypass was unavoidable to prevent loss of life, personal injury or
severe property damage;
(b) 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
gC, LI=. 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
(a) The permittee submitted notices as required under Paragraph c. of
this section.
(2) 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. (1) of this section.

a. Definition.
"Upset " 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.
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.
A permittee who wishes to establish the affirmative defense of upset
shall demonstrate, through properly signed, contemporaneous operating
logs, or other relevant evidence that:
(1) An upset occurred and that the permittee can identify the causes) of
the upset;
