PART I INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to be covered by this General Permit must register with the Division of
,,
Water Quality by the filing of a Notice of Intent (NOI) and applicable fees. The NOI shall be
submitted and a certificate of coverage issued prior to any discharge of stormwater associated
with industrial activity that has a point source discharge to the surface waters of the state.
Any owner or operator not wishing to be covered or limited by this ,General Permit may make
application for an individual NPDES permit in accordance with NPDES procedures in 15A
NCAC 2H .0100, stating the reasons supporting the 'request. Any application for an individual
permit should be made at least 180 days prior to commencement of discharge.
This General Permit does not cover activities or discharges covered by an individual NPDES
permit until the individual permit has expired or has Been revoked. Any person conducting an
activity covered by an individual permit but which could be covered by this General Permit may
request that the individual permit be revoked and coverage under this General Permit be
provided.
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
Certification must submit a No Exposure Certification .NOI form to,the Division, must receive
approval by the Division, must maintain no exposure conditions unless authorized to discharge
under a valid NPDES stormwater permit, and must reapply for the No Exposure Exclusion once
every five (5) years. - ,1. : t
.Facilities submitting NOIs for -coverage under this permit, and facilities submitting renewal
forms for continued coverage under this permit;'prior to establishment or approval of a Total
Maximum Daily Load (TMDL) for pollutant(s) fovstormwater. discharges .(i.e. wet weather
flows), may be covered under this permit during its term. For such facilities, continued coverage
under the reissuance of this permit is subject to the facility demonstrating that it does not have a
reasonable potential to violate applicable water quality standards for such pollutants due to the
stormwater discharge(s). For facilities that do have a reasonable potential for violation of
applicable water quality standards due to the stormwater discharge(s), the facility shall apply for
an. individual permit 180 days prior to the expiration of.this general permit. Once the individual
permit is issued and becomes effective the,facilit -- %fill no iongenhave.coverage under the
general permit. Impaired waters scheduled for TMDL development'are on North Carolina's
303(d) List and can�be:found here:

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 111, 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 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. 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) of concern are.
North Carolina's 303(d) List can be found here:

(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 1I Page 1 of 10

Permit No. NCG210000
(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 III, 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 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 Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section
313 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in any amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table
or summary of all such tanks and stored materials and their associated secondary
containment areas shall be maintained. If the secondary containment devices are
connected 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 stonnwater 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.
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
Part 11 Page-'! of 10

Permit No. NCG2I0000
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 titres during facility operations that have the potential to
contaminate stormwater'rtinoff 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. The program shall list
all stbrmwater 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
facility systems that present a potential for stormwater 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.
S. Employee Training. Training programs shall be developed and trainin'g'provided at a
minimum on an IannuaI basis for facility`personnel'with'responsibilities for: spill response
and,cleanup,'pre.ventative'maintenance' activities, and for any of the facility's operations
that have -the potential to contaminate,stordiwater 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'as'signments'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 in 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 ihat 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
effectiveness of the BMPs listed in the,BMP Summary of the Stormwate'r Management
Plan.
The Director'nmay notify tl e.permittee H,hen the'Plan-does not meet one or more of the
minimum requirements of the permit: Within 30 days of,such:notice, the'permittee shall
submira time schedule to the Directar'for'modifying the Plan to meet minimum
Part 11 Page 3 of 10

Permit No. NCG210000
requirements. The permittee shall provide certification in writing (in accordance with
Part Ili, 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-annually). These facility inspections
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part II of this permit.
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
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 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. A facility
that does not retain exposed (either exposed to incident precipitation or exposed to stormwater run on)
piles of sawdust, wood chips, bark, mulch, or other similar material on site for more than seven (7) days
before removing the material is not required to monitor the parameters in Table 1. A facility that is
exempt from analytical monitoring on this basis of removing material in seven (7) days or less shall
keep in its SPPP a record of dates when the material is generated and removed, and how/by whom it was
removed. If at any time the material is not removed within this time frame, the facility must begin
analytical monitoring immediately. All facilities covered by this permit must perform Qualitative
Monitoring In Section C. of this Part.

3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless representative outfall
status has been granted.
4 For each sampled representative storm event the total precipitation must be recorded. An on -site rain gauge or local rain
gauge reading must be recorded.
Part 11 Page 4 of 10

Permit No. NCG210000
No monitoring is required if the facility does not retain exposed piles of sawdust, wood chips, bark, mulch, or other
similar material on site for more than seven (7) days. If a facility opts out of monitoring on the basis of removing
accumulated material in seven (7) days or less, the facility shall record and maintain a log in its SPPP of dates of when
material is generated and removed, and details about how/by whom it was removed.
All analytical monitoring shall be performed during a representative storm event 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.
The permittee shall complete the analytical samplings in accordance with the schedule specified
in Table 2. 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.

1 Monitoring Location: Qualitative monitoring shall be performed at each
stormwater discharge outfall (SDO) regardless of representative outfall status.
If the permittee's qualitative monitoring indicates either 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 appropriate. A
written record of the permittee's investigation, evaluation, and response actions shall be kept in the
Stormwater Pollution Prevention Plan.
Qualitative monitoring is for the purposes of evaluating the effectiveness of the Stormwater
Pollution Prevention Plan (SPPP), assessing new sources of stormwater pollution, and prompting
the permittee's response actions 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, DWQ may:
• require that the permittee revise, increase, or decrease the monitoring frequency for the
remainder of the permit;
• rescind coverage under the General Permit, and require that the permittee apply for an
individual stormwater discharge permit,

PART I INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to be covered by this General Permit must register with the Division of
Water Quality by the filing of a Notice of Intent (NOI) and applicable fees. The NOI shall be
submitted and a certificate of coverage issued prior to any discharge of stormwater associated
with industrial activity that has a point source discharge to the surface waters of the state.
Any owner or operator not wishing to be covered or limited by this General Permit may make
application for an individual NPDES permit in accordance with NPDES procedures in 15A
NCAC 2H .0100, stating the reasons supporting the request. Any application for an individual
permit should be made at least 180 days prior to commencement of discharge.
This General Permit does not cover activities or discharges covered by an individual NPDES
permit until the individual permit has expired or has been revoked. Any person conducting an
activity covered by an individual permit but which could be covered by this General Permit may
request that the individual permit be revoked and coverage under this General Permit be
provided.
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
Certification must submit a No Exposure Certification NOI form to the Division, must receive
approval by the Division, must maintain no exposure conditions unless authorized to discharge
under a valid NPDES stormwater permit, and must reapply for the No Exposure Exclusion once
every five (5) years.
Facilities submitting NOIs for coverage under this permit, and facilities submitting renewal
forms for continued coverage under this permit, prior to establishment or approval of a Total
Maximum Daily Load (TMDL) for pollutant(s) for stormwater discharges (i.e. wet weather
flows), may be covered under this permit during its term. For such facilities, continued coverage
under the reissuance of this permit is subject to the facility demonstrating that it does not have a
reasonable -potential to violate applicable water quality standards for such pollutants due to the
stormwater discharge(s). For facilities that do have a reasonable potential for violation of
applicable water quality standards due to the stormwater discharge(s), the facility shall apply for
an individual permit. 180 days prior to the expiration of this general permit. Once the individual
permit is issued and becomes effective the facility will no longer have coverage under the general
permit. Impaired waters scheduled for TMDL development are on North Carolina's 303(d) List
and can be found here: http./Ih2o.enr.state.nc.us/tmdl/General_303d.htm#Downloads.
A list of approved TMDLs for the state of North Carolina can be found here:
http://h2o.enr.state.ne.us/tmdllGeneral_TMDLs.htm.
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.
Part I Page 1 of 2

Permit No. NCG1 10000
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 which has
been adequately treated and managed in accordance with the terms and conditions of this General
Permit. All 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 General 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 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 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 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. The
general location map (or alternatively the site map) should 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) of concern are.
North Carolina's 303(d) List can be found here:

North Carolina TMDL documents can be found here:
httn /At2o.enr.state.nc.tis/tmdl/`'Ml)l,_list.htin inal_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 points, 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, direction of flow, drainage areas
for each outfall, industrial activities occurring in each drainage area, buildings,
existing and proposed 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 1 of 8

Permit No. NCG 110000
(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 III, Standard Conditions, Section
B, Paragraph S. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
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 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 by permanent or semi -permanent covers. 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 Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section
313 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in any amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table
or summary of all such tanks and stored materials and their associated secondary
containment areas shall be maintained, and shall record the volume capacity of
each tank and containment area. 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 narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, diversion structures,
secondary containment structures, 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.
Part II Page 2 of 8

Permit No. NCGI 10000
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. The program shall specifically
identify industrial areas that have the potential for soil erosion, and must specifically note
the preventative BMP or maintenance activity implemented in the areas, and must include
regular inspections of the areas.
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 be documented
and position assignments provided.
7. 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 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.
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.
Facility Inspection Program. Inspections of the facility and all stormwater systems shall
occur 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
Part 11 Page 3 of 8

Permit No. NCG 110000
days separating inspection dates (unless performed more frequently). 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 systerns. Records of these
inspections shall be incorporated into the Stormwater Pollution Prevention Plan. These
facility inspections are different from, and in addition to, the stormwater discharge
characteristic monitoring required in Part I1 of this permit.
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
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 years and made available to the Director or the Director's authorized representative
immediately upon request.
SECTION B: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified below in Table 1. No analytical
tests are required. Qualitative monitoring of stormwater outfalls must be performed during a
representative storm event.
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.

I Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall (SDO)
regardless of representative outfall status.
If the permittee's qualitative monitoring indicates either 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 appropriate. A written record of the permittee's investigation, evaluation, and
response actions shall be kept in the Stormwater Pollution Prevention Plan.
Qualitative monitoring is for the purposes of evaluating the effectiveness of the Stormwater
Pollution Prevention Plan (SPPP), assessing new 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, DWQ may:
• require that the permittee revise, increase, or decrease the monitoring frequency for the
remainder of the permit;
• rescind coverage under the General Permit, and require that the pertittee apply for an
individual stormwater discharge permit;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures; or
• require that the permittee implement site modifications to qualify for the No Exposure
Exclusion.
Part H Page 5 of 8

Permit No. NCG 110000
Qualitative monitoring will be performed twice per year, in accordance with the schedule in
Table 2. A minimum of 60 days must separate Period I and Period 2 monitoring dates,
unless monthly sampling has been instituted under a Tier Two response for vehicle maintenance
activity areas.

The following information is included with your permit package:
• A new Certificate of Coverage
• A copy of stormwater General Permit NCG110000
• A copy of a Technical Bulletin for the General Permit
• Five copies of the Discharge Monitoring Report (DMR) Form
• Five copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater only, and it specifies your obligations with respect to stormwater
discharge controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself with all
the changes inthereissued permit.
The more significant changes in the General Permit since the your last Certificate of Coverage include the following:
• Permit cover page — Coverage is expanded to include industrial activities similar to the categorically identified industries.
• Part I Section A — This part explains that the No Exposure Exclusion from permitting option may be available to the
permittee.i
• Part 11 Section A — Several minor expansions and clarifications of the required content of the Stormwater Pollution
Preventio6 Plan have been added. Please be sure that your plan is updated to comply with the new requirements.
• Part II Section B — Qualitative monitoring must now be conducted during a representative storm event.
• Part II Section B — The permittee is required to keep a written record of his response to problems identified by his
qualitative monitoring observations.
+ Part 11 Section C - For facilities with vehicle maintenance activities using more than 55 gallons of new motor oil per month,
new provisions require that discharges from the vehicle maintenance areas be sampled twice per year, and that the
sampling 'results be compared to new numerical benchmark values. (The previous cutoff concentrations have been
eliminated.)
• Part 11 Section C -- For facilities with vehicle maintenance activities using more than 55 gallons of new motor oil per month,
new provisions require the permittee to execute Tier One and Tier Two response actions, based on the first benchmark
exceeden'ce (Tier One) and the second consecutive benchmark exceedence (Tier Two). Tier Two requires that the
permittee institute monthly monitoring instead of twice -per -year monitoring, until three consecutive monitoring events
show no benchmark exceedences.
• Part II Section C — This part contains a new provision that four exceedences of any particular benchmark will trigger
increased DWQ involvement in the permittee's stormwater management and control actions. DWQ may direct the
permittee: to apply for an individual permit, or may direct the implementation or installation of specific stormwater control

PART I INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to be covered by this General Permit must register with the Division of
Water Quality by the filing of a Notice of Intent (NOI) and applicable fees. The NOI shall be
submitted and a certificate of coverage issued prior to any discharge of stormwater associated
with industrial activity that has a point source discharge to the surface waters of the state.
Any owner or operator not wishing to be covered or limited by this General Permit may make
application for an individual NPDES permit in accordance with NPDES procedures in 15A
NCAC 2H .0100, stating the reasons supporting the request. Any application for an individual
permit should be made at least 180 days prior to commencement of discharge.
This General Permit does not cover activities or discharges covered by an individual NPDES
permit until the individual permit has expired or has been revoked. Any person conducting an
activity covered by an individual permit but which could be covered by this General Permit may
request that the individual permit be revoked and coverage under this General Permit be
provided.
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
Certification must submit a No Exposure Certification NOI form to the Division, must receive
approval by the Division, must maintain no exposure conditions unless authorized to discharge
under a valid NPDES stormwater permit, and must reapply for the No Exposure Exclusion once
every five (5) years.
Facilities submitting NOIs for coverage under this permit, and facilities submitting renewal
forms for continued coverage under this permit, prior to establishment or approval of a Total
Maximum Daily Load (TMDL) for pollutant(s) for stormwater discharges (i.e. wet weather
flows), may be covered under this permit during its term. For such facilities, continued coverage
under the reissuance of this permit is subject to the facility demonstrating that it does not have a
reasonable potential to violate applicable water quality standards for such pollutants due to the
stormwater discharge(s). For facilities that do have a reasonable potential for violation of
applicable water quality standards due to the stormwater discharge(s), the facility shall apply for
an individual permit 180 days prior to the expiration of this general permit. Once the individual
permit is issued and becomes effective the facility will no longer have coverage under the general
permit. Impaired waters scheduled for TMDL development are on North Carolina's 303(d) List
and can be found here: http://h2o.enr.state.nc.us/tmdUGeneral_303d.htm#Downloads.
A list of approved TMDLs for the state of North Carolina can be found here:
http://h2o.enr.state.nc.us/tmdl/Gencral_TMDLs.htm.
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.
Part I Page 1 of 2

Permit No. NCG050000
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 which has
been adequately treated and managed in accordance with the terms and conditions of this General
Permit. All 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 General 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 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 general permit. The Plan shall include, at a minimum,
the following items:
l . 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. The
general location map (or alternatively the site map) should 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) of concern are.
North Carolina's 303(d) List can be found here:
http://h2o.enr.state.ne-us/tmdl/General_303d.htm#Downloads
North Carolina TMDL documents can be found here:
http://h2o.enr.state.ne.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 points, 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, direction of flow, drainage areas
for each outfall, industrial activities occurring in each drainage area, buildings,
existing and proposed 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.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
Part 11 Page 1 of 8

Permit No. NCGO50000
accordance with the requirements found in Part III, 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 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 by permanent or semi -permanent covers. 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 Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section
313 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in any amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table
or summary of all such tanks and stored materials and their associated secondary
containment areas shall be maintained, and shall record the volume capacity of
each tank and containment area. 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 narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, diversion structures,
secondary containment structures, 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.
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 team) responsible for implementing the
Part II Page 2 of 8

Permit No. NCG050000
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. The program shall specifically
identify industrial areas that have the potential for soil erosion, and must specifically note
the preventative BMP or maintenance activity implemented in the areas, and must include
regular inspections of the areas.
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 be documented
and position assignments provided.
7. 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 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.
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 Inspection Program. Inspections of the facility and all stormwater systems shall
occur 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). 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
Part II Page 3 of 8

Permit No. NCG050000
the facility's stormwater control systems, plant equipment and systems. Records of these
inspections shall be incorporated into the Stormwater Pollution Prevention Plan. These
facility inspections are different from, and in addition to, the stormwater discharge
characteristic monitoring required in Part 11 of this permit.
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
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 years and made available to the Director or the Director's authorized representative
immediately upon request.
SECTION B: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified below in Table 1. No analytical
tests are required. Qualitative monitoring of stormwater outfalls must be performed during a
representative storm event.
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.

Part II Page 4of8

Permit No. NCG050000
If the pennittee's qualitative monitoring indicates either 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 appropriate. A written record of the permittee's investigation, evaluation, and
response actions shall be kept in the Stormwater Pollution Prevention Plan.
Qualitative monitoring is for the purposes of evaluating the effectiveness of the Stormwater
Pollution Prevention Plan (SPPP), assessing new sources of stormwater pollution, and prompting
the permittee's response actions 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, DWQ may:
• require that the permittee revise, increase, or decrease the monitoring frequency for the
remainder of the permit;
• rescind coverage under the General Permit, and require that the permittee apply for an
individual stormwater discharge permit;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures; or
• require that the permittee implement site modifications to qualify for the No Exposure
Exclusion.
Qualitative monitoring will be performed twice per year, in accordance with the schedule in
Table 2. A minimum of 60 days must separate Period 1 and Period 2 monitoring dates,
unless monthly sampling has been instituted under a Tier Two response for vehicle maintenance
activity areas.

PERMITTED DISCHARGES
SECTION A: STORMWA,rER IIES'1' MANAGI+,MEN'1' 1'RAC'I'ICES (LIMPS) PLAN
The permittee shall implement stormwater BMPs to ensure that contaminants do not enter
surface waters via stormwater that comes in contact with any unstabilized overburden,
raw materials, intermediate products, finished products, byproducts or waste products
located on the site covered by this permit. A BMP Plan shall be developed in accordance
with the requirements of this section. The BMP Plan requirement, or portions of the plan
requirement, may be met by utilizing appropriate requirements in other documented plans
specific to the permitted facility.
2. Management of Stormwater Runoff and Runon. The permittee shall maintain stormwater
BMPs for land disturbance areas and outside process areas. In addition, controls should
be used to limit or isolate selected land disturbance and process areas and limit the
amount of off site stormwater runon to those areas. Appropriate Best Management
Practices (BMPs) should be used to divert, infiltrate, reuse or otherwise manage
stormwater runoff and R111011. in a planner that reduces pollutants in stormwater
discharges leaving the site. Appropriate BMPs may include but are not limited to:
vegetative swales, berms, use of reclaimed aline areas, and reuse of collected stormwater
(such as for an industrial process or as an irrigation source).
3. BMP Controls inspection and Maintenance. All stormwater BMPs shall be inspected by
or under the direction of the permittee at least once every seven calendar days and within
24 hours after any storm event that results in a discharge. The BMPs implemented shall
be operated and maintained so that they are cleaned out when the sediment storage
capacity has been reduced by 50%. If any visible sedimentation is leaving the property,
corrective action shall be taken to reduce the discharge of sediments. Visible
sedimentation found offsite shall be recorded with a brief explanation as to the measures
taken to prevent future releases as well as any measures taken to remove the sediment that
left the site. All other stormwater specific controls (e.g. oil /water separators) shall be
inspected and qualitatively monitored (as per Part E11.13.3) on a semiannual schedule, once
in the fall (September -November) and once during the spring (April -June). A log of
sampling data and of activities taken to implement BMPs associated with the vehicle
maintenance activities shall be maintained and incorporated into the BMP Plan and kept
onsite for the duration of the permit term and made available to the Director upon request.
4. Erosion and Sedimentation Control. The permittee shall implement the management
practices and the erosion and sedimentation control measures that are included in the
mining permit or erosion and sedimentation control permit issued by the Division of Land
Resources. Compliance with the issued permit is considered a requirement of this
general permit. Any deviation from the issued permit, or amendments to the issued
permit, that impacts water quality shall constitute a violation of the terms and conditions
of this general permit. A signed copy of the issued permit including the approved erosion
and sedimentation control measures and the reclamation plan shall be maintained on the

runoff. If the secondary containment devices are connected directly to stornlwater
conveyance systems, the connection shall be controlled by manually activated valves or
other similar devices (which shall be secured with a locking nicellaillsill) and any
stornlwater that accumulates in the containment area shall be at a nlllllillunl visually
observed for color, foam, outfall stainino, visible sheens and dry weather flow, prior to
release of the accumulated stormwater. Accumulated stormwater shall be released if
found to be uncontaillinated by the material stored within the containment area.
SECTION B: ANALYTICAL. AND QUALITATIVE MONITORING REQUIREMENTS
FOR DISCHARGES COMPOSED ENTIRELY OF STORMWATER
Analytical monitoring for stormwater discharges shall be performed for parameters as specified
in Tables I through 4. All analytical monitoring shall be performed during a representative storm
event as defined in Part VII. For each parameter, the arithmetic mean of all analytical sampling
results collected during the terns of the permit may be calculated for each individual outfall and
compared to the cut-off concentrations listed in Tables 2 and 4. If the arithmetic mean is less
than the specified CLIt-off concentration fora given parameter, the facility is not required to
continue annual monitoring for that parameter (at that outfall) until the last year of the permit
unless a significant change ill facility operations or configuration occurs. If I cut-off
concentration results in discontinued analytical monitoring at an individual discharge outfall, the
pernlittee is required to maintain facility operations that ensure the continuation of stormwater
runoff quality. The permittee must perform analytical sampling during the first and last ,year of
the permit terns regardless of cut-off concentration conditions.
In situations where stornlwater runoff is controlled by some type basin or retention/detention
pond, the following provisions are applicable for sample collection for analytical monitoring:
• Analytical monitoring for stormwater discharges from a basin or other similar control
structures must be performed within the first 30 Minutes of discharge.
Part III Page 2 of 9

Permit No. NCG020000
• Analytical monitoring for a basin /pond designed to contain the I0-year desit'n storm (see
I'MI V11, D(2finitions) without c11SC11dr&In(r is not required. Qualitative monitoring for color,
foam, Outtall staininb, visible sheen and dry weather flow is the only monitoring requirement.
• Analytical and qualitative morlitOrin) are not required for a basin/pond designed to contain
the 25-year, 24-dour storm (see Part V11, Definitions) without discharing. A basin/ pond
meeting this provision is considered a non -discharging stormwater control.
I. analytical Monitoring for Stormwater Discharges from Land Disturbance and

PART I INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to be covered by this General Permit must register with the Division of
Water Quality by the filing of a Notice of Intent (NOI) and applicable fees. The NOI shall be
submitted and a certificate of coverage issued prior to any discharge of stormwater associated
with industrial activity that has a point source discharge to the surface waters of the state.
Any owner or operator not wishing to be covered or limited by this General Permit may make
application for an individual NPDES permit in accordance with NPDES procedures in 15A
NCAC 2H .0100, stating the reasons supporting the request. Any application for an individual
permit should be made at least 180 days prior to commencement of discharge.
This General Permit does not cover activities or discharges covered by an individual NPDES
permit until the individual permit has expired or has been revoked. Any person conducting an
activity covered by an individual permit but which could be covered by this General Permit may
request that the individual permit be revoked and coverage under this General Permit be
provided.
Facilities submitting NOIs for coverage under this permit, prior to establishment or approval of a
Total Maximum Daily Load (TMDL) for a priority pollutant(s) for stormwater discharges (i.e.
wet weather flows), may be covered under this permit during its term. For such facilities
continued coverage under the reissuance of this permit is subject to the facility demonstrating
that it does not have a reasonable potential to violate applicable water quality standards for such
pollutants due to the stormwater discharge(s). For facilities that do have a reasonable potential
for violation of applicable water quality standards due to the stormwater discharge(s) the facility
shall apply for an individual permit 180 days prior to the expiration of this general permit. Once
the individual permit is issued and becomes effective the facility will no longer have coverage
under the general permit. A list of approved TMDLs for the state of North Carolina can be found
at http://h2o.enr.state.nc.us/trndl/General TMDLs.htm
During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge stormwater and/or process wastewater associated with
industrial activity as defined in this permit. Such discharges shall be controlled, limited and
monitored as specified in this permit. Although this permit requires submittal of analytical
monitoring results annually, discharges occurring throughout the year must meet the conditions
and limitations of this permit.
SECTION B: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater and process wastewater to the surface waters of North Carolina or separate storm
sewer system which has been adequately treated and managed in accordance with the terms and
conditions of this General Permit. All discharges shall be in accordance with the conditions of
this permit.
Part 1 Page 1 of 2

Permit No. NCG 140000
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 discharges allowed by this General 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.
SECTION C: PERMIT RENEWAL
Dischargers covered by general permits need not submit new Notices of Intent or renewal
requests unless so directed by the Division. If the Division chooses not to renew a general
permit, all facilities covered under that general permit shall be notified to submit applications for
individual permits or notified to take other appropriate actions at the discretion of the Director.

PART I1 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 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. 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 list of the potential pollutant sources which may be expected to contribute to
contamination of stormwater discharges
(c) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(d) 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.
(e) A list of significant spills or leaks of pollutants (see definitions) that have
occurred at the facility during the 3 previous years and any corrective actions
taken to mitigate spill impacts.
(1) 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 I1I, Standard Conditions, Section
B, Paragraph S.
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
Part 1l Page] of l 1

Permit No. NCG140000
nonstructural measures. The stormwater management plan, 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 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 313 of Title III of the
Super -fund 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 have a
drain, the drain shall be controlled by manually activated valves or other similar
devices, which shall be secured with a locking mechanism. If there is no drain, the
containment shall be observed and pumped out as needed to maintain adequate
capacity. Any stormwater that accumulates in the containment area shall be at a
minimum visually observed for color, foam, outfall staining, and visible sheens,
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 BMWs 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.
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 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

Permit No_ NCG140000
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 for all
employees 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. 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 be documented
and position assignments provided.
7. 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. Revision dates should
be included on the pages changed.
The Director, or his designee, 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, or his designee, 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,
or his designee, that the changes have been made.
8. Facility Inspection Program. Facilities are required to inspect all BMP's and stormwater
systems on at least a semiannual schedule, once in the fall (September -November) and
once during the spring (April - June). The inspection and any subsequent maintenance
activities performed shall be documented, recording date and time of inspection,
individual(s) making the inspection, and any comments. Records of these inspections
shall be incorporated into the Stormwater Pollution Prevention Plan.
Stormwater discharge characteristic monitoring as required in Part H 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

SECTION B. ANALYTICAL MONITORING REQUIREMENTS - STORMWATER
DISCHARGE
l . Stormwater associated with industrial activity that is not combined with process
wastewater
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 that is not combined with process wastewater subject to the provisions of this
permit. Analytical monitoring of stormwater discharges shall be performed as specified
below in Table 1.
For each parameter, the arithmetic mean of all analytical sampling results collected
during the term of the permit shall be calculated for each individual outfall. The
computed arithmetic mean is then compared to the cut-off concentrations listed below in
Table 2. If the arithmetic mean is less than the specified cut-off concentration for a given
parameter, then the facility is not required to continue annual analytical monitoring for
that parameter (at that outfall) during the remaining term of the permit unless a significant
change in facility operations or configuration occurs. If a cut-off concentration results in
discontinued analytical monitoring at an individual discharge outfall, the permittee is
required to maintain facility operations that ensure the continuation of stormwater runoff
quality.
TheMrmittee must perform_anal)gical sampling of stormwater discharges during the first
and last year of the permit coverage regardless of cut-off concentration conditions.
Analytical results from sampling during the final year of the permit coverage must be
submitted with the permit renewal application. All analytical monitoring shall be
performed during a representative storm event.

2 If the stormwater runoff is controlled by a stormwater detention pond, a grab sample of the discharge
from the pond shall be collected within the first 30 minutes of discharge. If the detention pond
discharges only in response to a storm event exceeding a ten year design storm, then no analytical
monitoring is required and only qualitative monitoring shall be performed. In all cases, water leaving the
pond is to meet permit requirements.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status has been granted.
4 For each sampled representative storm event the total precipitation, storm duration, and total flow must
be monitored. 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.

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 shall
perform analytical monitoring as specified below in Table 3. This monitoring shall be
performed at all outfalls which discharge stormwater runoff from the vehicle maintenance
areas.
For each parameter, the arithmetic mean of all analytical sampling results collected
during the coverage of the permit shall be calculated for each individual outfall. The
computed arithmetic mean is then compared to the cut-off concentrations listed below in
Table 4. If the arithmetic mean is less than the specified cut-off concentration for a given
parameter, then the facility is not required to continue annual analytical monitoring for
that parameter (at that outfall) during the remaining coverage of the permit unless a
significant change in facility operations or configuration occurs. If a cut-off
concentration results in discontinued analytical monitoring at an individual discharge
outfall, the permittee is required to maintain facility operations that ensure the
continuation of stormwater runoff quality.
The permittee must perform analytical sampling during the first and last year of the
permit coverse regardless of cut-off concentration conditions. Analytical results from

SECTION C: ANALYTICAL MONITORING REQUIREMENTS - PROCESS
WASTEWATER
This general permit authorizes the discharge of process wastewater associated with four distinct
activities. 1) Vehicle and equipment cleaning - external surfaces; 2) Overflow from recycle
systems that receive stormwater runoff; 3) Wetting of raw material stockpiles; 4) Mixing drum
cleaning. Discharge of process wastewater generated by any other activity is not authorized
under this permit. In the event that authorized process wastewaters commingle prior to
discharge, sampling the combined discharge will meet the conditions of this permit for those
separate activities, with respect to the annual sample. In the case of commingled process
wastewater, the most stringent of the applicable limits will apply.
Note: For facilities which route stormwater and all process wastewater to a recycle system,
no analytical monitoring of process wastewater discharges is required if that recycle
system discharges only as a result of a 10 year - 24 hour precipitation event.
Process Wastewater Associated with Vehicle and Equipment Cleaning
During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge process wastewater associated with vehicle and equipment
cleaning subject to the provisions of this permit. For the purposes of this permit, vehicle and
equipment cleaning is limited to the rinsing of the external surfaces of vehicles and equipment.
If detergents are used, they must be biodegradable and the pH adjusted to 6 to 9 standard units.
With or without the use of detergents, wastewater released to the waters of the State must meet
the requirements of Table 5
Analytical monitoring of process wastewater associated with vehicle and equipment cleaning
discharges shall be performed as specified below in Table 5. Annual analytical monitoring shall
be performed during a process wastewater discharge event associated with vehicle and
equipment cleaning.

2. Process Wastewater Associated with Recycle. Systems
During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge process wastewater associated with the overflow of recycle
systems subject to the provisions of this permit. Overflow discharge refers to a discharge
associated with precipitation events in excess of the design storm, which produces influent that
exceeds the design capacity of the system.
Note: By design, a recycle system is closed loop and should not discharge on a
routine or continuous basis. As such, the routine or continuous discharge of
process wastewater from recycle systems is not authorized under this permit.
Analytical monitoring of process wastewater associated with the overflow of recycle system
discharges shall be performed as specified below in Table 6. All analytical monitoring shall be

The SPPP should include the use of
Best Management Practices (BMPs)
to control discharge of pollutants
from a facility's stormwater out -
falls. BMPs include a variety of
things that the industrial facility
can do to minimize the potential for
pollutants to get into the stormwa-
ter draining from a facility. There
are different types of BMPs:
Non-Str-itctural BMPs
Non-structural ()ractices or activi-
ties) BMPs include:
* Eliminate exposure of materials
and equipment wherever possible
by moving materials and equipment
to indoor locations.
* Practice good housekeeping on -
site. Keep materials handled and
stored at the facility in an orderly
fashion.
* Exchange hazardous materials
for non -hazardous ones wherever
possible.

Could I monitor at fewer
outfalls?
All outfalls associated with vehi-
cle maintenance must be moni-
tored. However, the facility may
request approval of "Represent-
ative Outfall Status." This status
allows analytical monitoring at
fewer outfalls. To request, repre-
sentative outfall status, send a
letter to the DWQ Regional Office
explaining which outfall(s) can be
considered representative of other
discharges and include all neces-
sary supporting documentation.
Where can I find more
information?
Additional information is avail-
able at our website (see right).

Possibly. A facility with any indus-
trial activity subject to the NPDES
Stormwater regulations that elimi-
nates all potential stormwater ex-
posure may be eligible for a No Ex-
posure Exclusion from a st,orniwa-
ter permit. A facility that meets

Do I need a certified lab to
analyze stormwater samples?
Monitoring under all NPDES per-
mits must be conducted in accor-
dance with test procedures ap-
proved under federal regulations in
40 CPR §136. All labs certified by
North Carolina perform analysis in
accordance with those procedures.
While N.C. certification require-
ments do not apply to stormwater
only discharges, any data gathered
under an NPDES permit must con
form to federal requirements. Us-
ing a certified lab is one way to en -

The stormwater oermittin
program's objective is to reduce the
pollutant load in stormwater runoff
bv:
1- Educating the permitted
community about stormwater
pollutants,
2- Encouraging the use of Best
Management Practices (BMPs)
to minimize the entry of
pollutants into stormwater, and
3- Using collected analytical data to
assess stormwater's contribution
to water pollution to help
prioritize controls in problem
areas.
Key Permit Requirements
❑ Implementation of a Stormwater
Pollution Prevention Plan (SPPP)
(Part 11, Section A).
❑ Provide secondary containment
for all bulk storage of liquid
materials. (Part II, Section A: 2.
(b))•
❑ Perform and document semi-
annual qualitative monitoring.
(Part II, Section B).
❑ Perform annual analytical
monitoring for vehicle
maintenance area, if present, and
submit the results on the
monitoring report forms
provided with the permit. (Part
II, Section C),
Obtaining Representative Outfall
^ Status
If a facility has more than one
stormwater outlall from the vehicle
maintenance area(s) then the permit
requires that all such outfalls be
monitored. However, the permit also
allows for the facility to request
"Representative Outfall Status".
Representative Outfall status allows
the facility to perform analytical
monitoring at a reduced number of
outfal Is. Application is made by a
letter to the Stormwater and General
Permits Unit clearly explaining which
Outfall(s) is/are to be considered
representative of other discharges
from the site. A copy of the site map
used in the SPPP that delineates
drainage areas, industrial activities,
and any other potential stormwater
pollutant exposures shall be included
with the letter to support the
application.
BMP's
The Stormwater Pollution Prevention
Plan should include the use of Best
Management Practices (B,MP's) to
control the discharge of pollutants
from a facility's stormwater outfa115.
BMP's include a variety of things
that the industrial facility can do in
order to minimize the potential for
pollutants to get into the stormwater
draining from a facility. The
following outlines some potential
types of BMP's.
Non -Structural BNIP's
Some examples of non-structural
(practices or activities) BMP's are as
follows:
• Eliminate exposure of materials
and equipment wherever possible
by moving materials and
equipment to indoor locations.
• A very effective and cost
effective BMP is to practice
good housekeeping on -site.
Keep materials handled and
stored at the facility in an orderly
fashion.
• Examine process and exchange
hazardous materials for non-
hazardous ones wherever
possible.
• Establish routine leak and
maintenance checks to minimize
the chance of spills before they
occur. When spills do occur,
clean them up immediately.

Establish bulk storage tank
protocols that minimize the risk
of spills during loading and
unloading procedures.
Store used pallets and process
waste dumpsters inside or under
a roof where water cannot flow
on or around them.
Structural BMP's
Some examples of structural
(equipment or devices) BMP's are as
follows:
• Build containment dikes around
the loading areas of bulk liquid
storage containers.
• Where practical, change painting
operations from liquid systems to
powdered systems that don't
generate solvent wastes.
• Build roofs and secondary
containment around any
materials stored outside so that
stormwater doesn't run onto them
and carry pollutants away with it.
No Exposure Certification
Facilities that eliminate all of their
potential stormwater exposures do
not require a stormwater permit.
Facilities that meet these conditions
need to complete an EPA No
Exposure Certification form and
mail that to our attention at;
N.C. Division of Water Quality
Water Quality Section
Stormwater and General Permits Unit
1617 Mail Service Center
Raleigh, N.C. 27699-1617
You can download a copy of the No
Exposure Certification (EPA Form
35 10-11) from our website,
http://h2o.enr.state.ne.us/su/storm
water.html. If facility changes its
operations so as to be exempt after it
has already obtained a permit it may
send a letter explaining the changes
that have been made and request
rescission of their existing permit.

Commonly asked questions
1) Do all stormwater outfalls need
to he analytically monitored?
Only those outfalls that drain areas of
the facility where vehicle
maintenance activities using over 55
gallons of new motor oil per month
need to be analytically monitored.
Also, see previous discussion on
representative outfall status.
2) What happens if when I pull
samples for my annual
analytical - monitoring I'm
unable to get a sample for one
of the parameters?
If this happens it is fine to go ahead
and just sample for the missing
parameter during the next
representative storm event, just be
sure to note the total rainfall, event
duration, and total flow apart from
the initial monitoring data.
3) Does a certified lab need to be
used to analyze stormwater
samples?
Yes, a North Carolina certified lab
must be used to perform analytical
monitoring. The only exception to
this rule is when measuring the value
of pH. pH values should be
measured in the field because they
may change considerably between
when the sample is pulled and it is
analyzed at the laboratory.
A list of certified labs can be found at
(http://www.esb-onr.state.nc.tis/lab/tic
cert.asp).
4) How do you average the first
year's analytical monitoring
results?
The measured concentration of a
particular pollutant collected during
the first year's analytical monitoring
is the average value for that
parameter since dividing it by one
gives the same value for cut-off
purposes.
5) What If I Sell My Business Or
The Name of My Business
Changes ?
The Division views changes of
name or ownership as a minor
modification and requires the
Director's approval. Name and
ownership changes require you to
complete a Name/Ownership
Change Form SWU-239. The form
is downloadable from our website.
ChanL3es in Reissued General
Permits
These permits include some
clarifying and updated language
throughout the permit. In addition
language has been added to address
coverage under these permits for
discharges to waters with approved
TMDLs (Part 1 Section A).
Language has also been added to
Part I Section B in reference to
water quality standards.

Dear Sir or Madam:
Your facility holds a general permit from the North Carolina Division.of Water Quality to
discharge stormwater associated with industrial activities performed at your facility. Please be
advised that the Asheville Regional Office will be performing NPDES stormwater inspections
sometime in the near future.
If this office has not previously inspected your facility, you should be prepared to demonstrate
compliance with all terms and conditions included in the permit. Specifically, we will'be
evaluating the following: your stormwater pollution prevention plan, stormwater outfall
locations, qualitative and analytical monitoring data and any other activities required by your
permit. Please note that any data reported to the State must be analyzed by a facility that has a
North Carolina laboratory certification, either as a full laboratory or as a facility certified to
perform on -site field testing. If you have any questions regarding the generation of your
facility's data, please feel free to call Gary Francies at [phone].
Copies of the general permits and accompanying documents can be accessed from the following
