PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and implement a Storrnwater Pollution Prevention Plan
(SPPP). The SPPP shall be maintained on site. The SPPP is public information in
accordance with Part III, Standard Conditions, Section E, paragraph 3 of this permit. The
SPPP shall include, at a minimum, the following items:
1. Site Overview. The Site Overview shall provide a description of the physical facility
and the potential pollutant sources that have the potential to contribute to
contamination of stormwater discharges. The Site Overview shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent
map) showing the facility's location in relation to transportation routes and surface
waters; the name of the receiving waters to which the stormwater outfalls
discharge; and accurate latitude and longitude of the points of stormwater discharge
associated with industrial activity. The general location map (or alternatively the
site map) shall identify whet er any receiving waters are impaired (on the state's
303(d) list of impaired water or if the site is located in a watershed for which a
TMDL has been established, d what the parameters of concern are.
(b) A narrative description of storag pr tices, loading and unloading activities,
outdoor process areas, dust or parti ate generating or control processes, and
waste disposal practices. A narrati description of the potential pollutants that
could be expected to be present in he s mwater discharge from each outfall, and a
discussion of failure modes that ay impact e risk for polluted stormwater
discharges.
(c) A site map drawn at a scale sufficient -to -clearly dep ct: the site property boundary;
the stormwater discharge outfalls; all on -site a jacent surface waters and,
wetlands; industrial activity areas (including storage of materials, disposal areas,
process areas, loading and unloading areas, and haul roads); site topography and
.finished grade; all drainage features and structures; drainage area boundaries and
total contributing area for each outfall; direction of flow in each drainage area;
industrial activities occurring in each drainage area; buildings; stormwater Best
Management Practices (BMPs); and impervious surfaces. The site map must
indicate the percentage of each drainage area that is impervious, and the site map
must include a graphic scale indication and north arrow.
(d) A list of significant spills or leaks of pollutants during the previous three (3) years
and any corrective actions taken to mitigate spill impacts.
Part II Page 1 d 11

Permit No. NCS000562
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The permittee shall re -certify annually that the
stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. The certification statement will be signed in accordance with the
requirements found in Part III, Standard Conditions, Section B, Paragraph 3.
2. Stormwater Management Strategy. The, Stormwater Management Strategy shall
contain a narrative description of the materials management practices employed which
control or minimize the stormwater exposure of significant materials, including
structural and nonstructural measures. The Stormwater Management Strategy, at a
minimum, shall incorporate the following:
(a) Feasibility Study. An annual review by site management of the technical and
economic feasibility of changing the methods of operations and/or storage practices
to eliminate or reduce exposure of materials and processes to rainfall and run-on
flows. Wherever practical, the permittee shall prevent exposure of storage areas,
material handling operations, manufacturing, and fueling operations. In areas
where elimination of exposure and/or prevention of run-on contact are not
practical, the Feasibility Study shall document,the basis for the management
decision that such controls are not feasible.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials including petroleum products 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 substancesin order to prevent leaks and spills from contaminating
stormwater runoff. A table or summary of all such tanks and stored materials and
their associated secondary containment areas shall be maintained. If the secondary
containment devices are connected to stormwater conveyance systems, the
connection shall be controlled by manually activated valves or other similar devices,
which shall be secured closed with a locking mechanism. Prior to release into the
stormwaters conveyance system, any stormwater that accumulates in containment
areas shall be at a minimum visually observed for color, foam, outfall staining,
visible sheens, and dry weather flow. Accumulated stormwater may be released if
found to be uncontaminated by any material. Records documenting the individual
making the observation or analyses, the visual and analytical description of the
accumulated stormwaters, and the dates and times of the releases shall be kept for a
period of five (5) years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and on data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
Part 11 Page 2 of 11

Permit No. NCS000562
selected site BMPs. The BMP Summary shall be reviewed by site management and
updated annually.
3. Spill Prevention and Response Procedures, The Spill Prevention and Response
Procedures (SPRP) shall incorporate an assessment of potential pollutant sources based
On a materials inventory of the facility. The SPRP shall address spill response and
failure mode preparations and responses. Site management shall identify facility
personnel responsible for implementing the SPRP in a Written list incorporated into the
SPRP along with dated signatures by each individual acknowledging his or her
responsibilities under the SPRP. A responsible person shall be on -site at all times
during facility operations that have the potential to contaminate stormwater runoff
through spills or exposure of,materials associated with the facility operations. The
SPRP must be site stormwater specific. Therefore, an oil Spill Prevention Control and
Countermeasure plan (SPCC) may be a component of the SPRP, but may not be
sufficient to completely address the stormwater aspects of the SPRP. The common
elements of the SPCC with the SPRP may be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Pr gram. A preventative
maintenance and good housekeeping program shall be veloped and implemented.
The program shall address all stor water control systems, stormwater discharge
outfalls, all on -site and adjacent su ace waters and wetlands, industrial activity areas
(including material storage areas, material handlin areas, disposal areas, process
areas, loading and unloading areas, \ d haul road , all drainage features and
structures, and structural BMPs. The rogram s all establish schedules of inspections,
maintenance, and housekeeping activ ties of s rmwater control systems, as well as
facility equipment, facility areas, and f cility' yytems that present a potential for
stormwater exposure or stormwater p llution where not already addressed under
another element of the SPPP. Inspectio of material handling areas and regular
cleaning schedules of these areas shall a incorporated into the program. Timely
compliance with the established schedu es for inspections, maintenance, and
housekeeping shall be recorded and mai tained in the SPPP.
5. Facility Inspections. Inspections of the fa iliLt
nd all stormwater conveyance and
control systems shall occur as part of the Pr ative Maintenance and Good
Housekeeping Program at a minimum on a)durin
nual schedule, once during the first
half of the year (January to June),/and oncee second half (July to December),
withat least 60 days separating inspectionnless performed more frequently
than semi-annually). These f ility inspecdifferent from, and in addition to,
the stormwater discharge cha acteristicmat the outUl required in Part 11
Sections B and C of this permit.
6. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill
response and cleanup, preventative maintenance activities, and for any of the facility's
operations that have the potential to contaminate stormwater runoff. The facility
Part II Page 3 of 11

Permit No. NCS000562
:personnel responsible for implementing the training shall be identified, and their
annual training shall be documented by the signature of each employee trained.
7. Responsible Party. Site management shall identify, and the SPPP shall document, a
specific position or positions responsible for the overall coordination, development,
implementation, and revision of the SPPP. Responsibilities for all components of the
SPPP shall be documented and position assignments provided.
8. SPPP Amendment and Annual Update. The permittee shall amend the SPPP
whenever there is a change in design, construction, operation, site drainage,
maintenance, or configuration of the physical features which may have a significant
impact on the potential for the discharge of pollutants to surface waters. All aspects of
the SPPP shall be reviewed and updated on an annual basis. The annual update
shall include all the aspects required immediately above in items 1-7; and a review and
comparison of monitoring analytical data to benchmark values over the pastyear,
including a discussion about Tiered Response status. The permittee shall use the
Division's Annual Summary Data Monitoring Report form, available from the
Stormwater Permitting Unit's website here:
http:././12ortal.ncdenr.org/web/wqlws/sulnpdess
The Director may notify the permittee when the SPPP does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee
shall submit a time schedule to the Director for modifying the SPPP to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
9. SPPP Implementation. The permittee shall implement the Stormwater Pollution
Prevention Plan and all appropriate BMPs to prevent contaminants from entering
surface waters via stormwater, Among other actions identified herein, implementation
of the SPPP shall include the 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. Such documentation shall be kept on -site for a period of five (5)
years and made available to the Director or the Director's authorized representative
immediately upon request.

Footnotes:
1 Maintain quarterly monitoring until either another permit is issued for this facility or until this permit
is revoked or rescinded. The permittee must submit an application for renewal of coverage before the
submittal deadline (180 days before expiration) to be considered for renewed coverage under the
permit The permittee must continue analytical monitoring throughout the permit renewal process,
even if a renewal permit is not issued until after expiration of this permit
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "No Flow" within 30 days of the end of the sampling period. For the first term of this
permit, the new facility start-up date is uncertain. Permittee need not sample for the listed
monitoring periods until the facility comes into operation. Accordingly, the "No Flow" monitoring
report is not required during the time before the facility comes into operation.
Failure to monitor quarterly per the permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified time period. "No discharge" from
an outfall, or inability to collect a sample because of adverse weather conditions during a
monitoring period does not constitute failure to monitor, as long as it is properly reported.
The permittee shall compare monitoring results to the benchmark values in Table 3. The
benchmark values in Table 3 are not permit limits, but should be used as management
guidelines for the permittee's responsive implementation of the Stormwater Pollution
Prevention Plan (SPPP).

SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to quickly evaluate the effectiveness of the
permittee's implementation of the SPPP, and to assess new sources of stormwater pollution,
and to prompt the permittee's response to observed pollution. Qualitative monitoring of
stormwater outfalls must be performed during a measurable storm event.
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed quarterly as
specified in Table 4, and concurrent with the required analytical monitoring events.
Inability to monitor because of adverse weather conditions must be documented in the
SPPP and recorded on the DMR (see Adverse Weather in Definitions). Only SDOs discharging
stormwater associated with industrial activity must be monitored.

1 Measurement Frequency: Four times per year during a measureable storm event. See Table 2 for
schedule of monitoring periods through the end of this permitting cycle. The permittee must continue
qualitative monitoring throughout the permit renewal process until a new permit is issued. Qualitative
monitoring must be continued quarterly, and is not eligible for the semi-annual monitoring frequency under
step-down provisions that apply to analytical monitoring.
2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(SDO) regardless of representative outfall status.
A minimum of 30 days must separate monitoring dates, unless additional sampling has
been instituted as part of other analytical monitoring requirements in this permit.
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are
ineffective, or that significant stormwater contamination is present, the permittee shall
investigate potential causes, evaluate the feasibility of corrective actions, and implement
Part I1 Page 10 of 11

Permit No. NCS000562
those corrective actions within 60 days of the qualitative monitoring event. A written
record of the permittee's investigation, evaluation, and response actions shall be kept in
the SPPP.
ualitative Monitoring Response
Qualitative monitoring is for the purposes of evaluating the effectiveness of the permittee's
implementation of the SPPP, and 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 indicated by qualitative monitoring, or if the discharge causes or contributes to a
water quality standard violation, DWQ may, but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency and
parameters (analytical or qualitative) for a specified time period;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.

To meet the intent of the monitoring required by this permit, all test procedures must produce
minimum detection and reporting levels and all data generated must be reported down to the
minimum detection or lower reporting level of the procedure. If no approved methods are
determined capable of achieving minimum detection and reporting levels below permit discharge
requirements, then the most sensitive (method with the lowest possible detection and reporting
level) approved method must be used.
S. j;g=sentative outfall
If a facility has multiple discharge locations with substantially identical stormwater discharges that
are required to be sampled, the permittee may petition the Director for representative outfall status.
If it is established that the stormwater discharges are substantially identical and the permittee is
granted representative outfall status, then sampling requirements may be performed at a reduced
number of outfalls.

PART I — INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to have facilities covered by this General Permit must register with the Division
of Water Quality (DWQ) 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 point source discharge of stormwater
associated with industrial activity 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 Exclusion
must submit a No Exposure Certification Notice of Intent (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 recertify the No Exposure Exclusion annually.
Any facility may apply for new or continued coverage under this permit until a Total Maximum
Daily Load (TMDL) for pollutants for stormwater is established. A TMDL sets a pollutant -loading
limit that affects a watershed, or portion of a watershed, draining to a specific impaired water. For
discharges to watersheds affected by a TMDL, coverage under this permit may depend on the
facility demonstrating it does not have reasonable potential to violate applicable water
quality standards for those pollutants as a result of discharges. If DWQ determines that
discharges have reasonable potential to cause water quality standard violations, the facility shall
apply for an individual permit 180 days prior to the expiration date of this General Permit. Once
that individual permit is effective, the facility will no longer have coverage under this General
Permit. Note that the permittee must identify impaired waters (scheduled for TMDL development)
and waters already subject to a TMDL in the Site Overview, as outlined in the Stormwater Pollution
Prevention Plan, Part 11, Section A.
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. NCG030000
SECTION B: PERMITTED ACTIVITIES
Until coverage under this permit expires or is modified or revoked, the permittee is authorized to
discharge stormwater to the surface waters of North Carolina, or to a separate storm sewer system,
which has been adequately treated and managed in accordance with the terms and conditions of
this General 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 discharges allowed by this General Permit shall not cause or contribute to violations of
Water Quality Standards.
Discharges authorized by this permit and site operations must meet applicable wetland standards,
as recorded in 1SA NCAC 213.0230 and .0231, and water quality certification requirements as
outlined in 15A NCAC 2H .OSOO.
This permit does not relieve the permittee's responsibility for compliance with any other applicable
federal, state, or local law, rule, standard, ordinance, order, or decree.

PART II — MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED
DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and implement a Stormwater Pollution Prevention Plan (SPPP). The
SPPP shall be maintained on site unless exempted from this requirement by the Division. The SPPP
is public information in accordance with Part III, Standard Conditions, Section E, paragraph 3 of this
permit. The SPPP shall include, at a minimum, the following items:
1. Site Overview. The Site Overview shall provide a description of the physical facility and the
potential pollutant sources that may be expected to contribute to contamination of stormwater
discharges. The Site Overview shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent map),
showing the facility's location in relation to transportation routes and surface waters; the
name of the receiving waters to which the stormwater outfalls discharge, or if the discharge
is to a municipal separate storm sewer system, the name of the municipality and the
ultimate receiving waters; and accurate latitude and longitude of the points of stormwater
discharge associated with industrial activity. The general location map (or alternatively the
site map) shall identify whether any receiving waters are impaired (on the state's 303(d)
list of impaired waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are.
(b) A narrative description of storage practices, loading and unloading activities, outdoor
process areas, dust or particulate generating or control processes, and waste disposal
practices. A narrative description of the potential pollutants that could be expected to be
present in the stormwater discharge from each outfall.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary; the
stormwater discharge outfalls; all on -site and adjacent surface waters and wetlands;
industrial activity areas (including storage of materials, disposal areas, process areas,
loading and unloading areas, and haul roads); site topography and finished grade; all
drainage features and structures; drainage area boundaries and total contributing area for
each outfall; direction of flow in each drainage area; industrial activities occurring in each
drainage area; buildings; stormwater Best Management Practices (BMPs); and impervious
surfaces. The site map must indicate the percentage of each drainage area that is
impervious, and the site map must include a graphic scale indication and north arrow.
(d) A list of significant spills or leaks of pollutants during the previous three (3) years and
any corrective actions taken to mitigate spill impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges. The
certification statement will be signed in accordance with the requirements found in Part 1I1,
Standard Conditions, Section B, Paragraph 3.

Permit No. NCG030000
Stormwater Management Strategy. The Stormwater Management Strategy shall contain a
narrative description of the materials management practices employed which control or
minimize the stormwater exposure of significant materials, including structural and
nonstructural measures. The Stormwater Management Strategy, at a minimum, shall
incorporate the following:
(a) Feasibility Study. An annual review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure of
materials and processes to rainfall and run-on flows. Wherever practical, the permittee
shall prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is not
practical, this review shall document the feasibility of diverting the stormwater run-on
away from areas of potential contamination.
(b) Secondary Containment Requirements and.Records. Secondary containment is
required for: bulk storage of liquid materials including petroleum products: storage in any
amount of Section 313 of Title III of the Suoerfund Amendments and Reauthorization Act
(SARA) water priority chemicals: and storage in any amount of hazardous substancesin
order to prevent leaks and spills from contaminating stormwater runoff. A table or
summary of all such tanks and stored materials and their associated secondary containment
areas shall be maintained. If the secondary containment devices are connected to
stormwater conveyance systems, the connection shall be controlled by manually activated
valves or other similar devices which shall be secured closed with a locking mechanism.
Any stormwater that accumulates in the containment area shall be at a minimum visually
observed for color, foam, outfall staining, visible sheens, and dry weather flow, prior to
release of the accumulated stormwater. Accumulated stormwater shall be released if found
to be uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time of the
release shall be kept for a period of five (5) years.
(c) BMP Summary. A listing of site structural and non-structural Best Management Practices
(BMPs) shall be provided. The installation and implementation of BMPs shall be based on
the assessment of the potential for sources to contribute significant quantities of pollutants
to stormwater discharges and on data collected through monitoring of stormwater
discharges. The BMP Summary shall include a written record of the specific rationale for
installation and implementation of the selected site BMPs. The BMP Summary shall be
reviewed and updated annually.
Spill Prevention and Response Procedures. The Spill Prevention and Response Procedures
(SPRP) shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel responsible for implementing the SPRP shall be
identified in a written list incorporated into the SPRP and signed and dated by each individual
acknowledging their responsibilities for the plan. A responsible person shall be on site at all
times during facility operations that have the potential to contaminate stormwater runoff
through spills or exposure of materials associated with the facility operations. The SPRP must
be site stormwater specific. Therefore, an oil Spill Prevention Control and Countermeasure
plan (SPCC) may be a component of the SPRP, but may not be sufficient to completely address
the stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may be
incorporated by reference into the SPRP.
Part 11 Page 2 of 10

Permit No. NCG030000
4. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance
and good housekeeping program shall be developed and implemented. The program shall
address all stormwater control systems (if applicable), stormwater discharge outfalls, all on -site
and adjacent surface waters and wetlands, industrial activity areas [including material storage
areas, material handling areas, disposal areas, process areas, loading and unloading areas, and
haul roads), all drainage features and structures, and existing structural BMPs. The program
shall establish schedules of inspections, maintenance, and housekeeping activities of
stormwater control systems, as well as facility equipment, facility areas, and facility systems
that present a potential for stormwater exposure or stormwater pollution where not already
addressed under another element of the SPPP. Inspection of material handling areas and
regular cleaning schedules of these areas shall be incorporated into the program. Timely
compliance with the established schedules for inspections, maintenance, and housekeeping
shall be recorded and maintained in the SPPP.
S. 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 at the outfalls required
in Part 11 B, C, and D of this permit.
Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill response and
cleanup, preventative maintenance activities, and for any of the facility's operations that have
the potential to contaminate stormwater runoff. The facility personnel responsible for
implementing the training shall be identified, and their annual training shall be documented by
the signature of each employee trained.
7. Responsible Party. The SPPP shall identify a specific person(s) or positions) responsible for
the overall coordination, development, implementation, and revision of the SPPP.
Responsibilities for all components of the SPPP shall be documented and position assignments
provided.
8. SPPP Amendment and Annual Update. The permittee shall amend the SPPP whenever there
is a change in design, construction, operation, site drainage, maintenance, or configuration of
the physical features which may have a significant effect on the potential for the discharge of
pollutants to surface waters. All aspects of the SPPP shall he reviewed and updated on an
annual basis. The annual update shall include:
(a) an updated list of significant spills or leaks of pollutants for the previous three (3)
years, or the notation that no spills have occurred (element of the Site Overview);
(b) a written re -certification that the stormwater outfalls have been evaluated for the
presence of non-stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on -site stormwater BMPs
(BMP Summary element of the Stormwater Management Strategy).
(d) a statement that annual training requirements were met in the year past;
(e) a review and comparison of sample analytical data to benchmark values (if
applicable) over the past year, including a discussion about Tiered Response status.
The permittee shall use the Division's Annual Summary Data Monitoring Report
(DMR) form, available from the Stormwater Permitting Unit's website (See
'Monitoring Forms' here: http_//portal.ncdenr.org/web/wq/ws/su/npdessw).
Part II Page 3 of 10

Permit No. NCG030000
The Director may notify the permittee when the SPPP does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall submit
a time schedule to the Director for modifying the SPPP to meet minimum requirements. The
permittee shall provide certification in writing (in accordance with Part III, Standard
Conditions, Section B, Paragraph 3) to the Director that the changes have been made.
9. SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention
Plan and all appropriate BMPs to prevent contaminants from entering surface waters via
stormwater. Implementation of the SPPP shall include documentation of all monitoring,
measurements, inspections, maintenance activities, and training provided to employees,
including the log of the sampling data and of actions taken to implement BMPs associated with
the industrial activities, including vehicle maintenance activities. Such documentation shall be
kept on -site for a period of five (S) years and made available to the Director or the Director's
authorized representative immediately upon request.
10. Solvent Management Plan. Facilities that implement a Solvent Management Plan may so
certify, and the requirement for Total Toxic Organics (TTO) monitoring in Part I1, Section B.
may be waived. The Solvent Management Plan shall include:
(a) an annually updated and quantified inventory of the total toxic organic compounds
present on site during the previous three years;
(b) a narrative description of the in -plant locations and uses of the toxic organic
compounds, the method of disposal including quantities disposed on- and off -site;
(c) the management procedures and engineering measures for assuring that toxic
organics do not spill or leak into stormwater.
DWQ may at its discretion require submittal, review, and approval of the Solvent Management
Plan as a condition of continuing the TTO sampling waiver. For those facilities electing to
employ the TTO sampling waiver, the permittee shall include the following signed certification
statement on each discharge monitoring report: "Based upon my inquiry of the person or persons
directly responsible for managing compliance with the permit monitoring requirementfor total
toxic or (TTO), I certify that to the best of my knowledge and belief, no leak, spill, or
dumping of concentrated toxic organics into the stormwater or onto areas which are exposed to
rainfall or stormwater runoff has occurred since filing the last discharge monitoring report. I
further certify that this facility is implementing all the provisions of the Solvent Management Plan
included in the Stormwater Pollution Prevention Plan."

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Permit No. NCG0300M
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a measureable storm event at trash stormwater
discharge outfall (SDO). Only SDOs discharging stormwater associated with industrial activity must
be sampled (See Definitions).
A measurable storm event is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office. See Definitions.

Footnotes:
1 Maintain semi-annual analytical monitoring throughout the permit renewal process (unless other
provisions of this permit prompt monthly sampling).
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "No Flow" or "No Discharge" within 30 days of the end of the sampling period.
Failure to monitor semi-annually per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period. "No discharge" from an outfail or
inability to collect a sample because of adverse weather conditions during a monitoring period, for
example does not constitute failure to monitor, as long as it is properly reported.
The permittee shall compare monitoring results to the benchmark values in Table 3. The benchmark
values in Table 3 are not permit limits but should be used as guidelines for the implementation of the
permittee's Stormwater Pollution Prevention Plan (SPPP). Exceedances of benchmark values require
the permittee to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs) in a tiered program. See below the descriptions
of Tier One, Tier Two, and Tier Three response actions. In the event that DWQ releases the permittee
from continued monthly monitoring under Tier Three, DWQ's release letter remains in effect through
the subsequent reissuance of this permit, unless the release letter provides for other conditions or
duration.

3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) that discharges
stormwater runoff from area(s) where vehicle maintenance activities occur.
4 For each sampled measureable storm event the total precipitation must be recorded. An on -site or local
rain gauge reading must be recorded. Where isolated sites are unmanned for extended periods of time, a
local rain gauge reading may be substituted for an on -site reading.
Failure to monitor semi-annually per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period, as provided in Part II Section B.
Monitoring results shall be compared to the benchmark values in Table 5. The benchmark values
in Table 5 are not permit limits but should be used as guidelines for the permittee's Stormwater
Pollution Prevention Plan (SPPP). Exceedances of benchmark values require the permiee to
increase monitoring, increase management actions, increase record keeping, and/or install
stormwater Best Management Practices (BMPs), as provided in Part 11 Section B.

SECTION D: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the permittee's
implementation of the SPPP and to assess new sources of stormwater pollution. Qualitative
monitoring of stormwater outfalls must be performed during a measurable storm event.
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed semi-annually as specified
in Table 6 and concurrent with the required analytical monitoring events (unless the permittee is
required to perform further qualitative sampling per the Qualitative Monitoring Response,
below). Inability to sample because of adverse weather conditions must be documented in the SPPP.
Only SDOs discharging stormwater associated with Industrial activity must be monitored (See
Definitions).

Permit No. NCGO30000
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are ineffective, or that
significant stormwater contamination is present, the permittee shall investigate potential causes, evaluate
the feasibility of corrective actions, and implement those corrective actions within 60 days, per the
Qualitative Monitoring Response, below. A written record of the permittee's investigation, evaluation,
and response actions shall be kept in the SPPP.
Mo
Qualitative monitoring is for the purposes of evaluating the effectiveness of the perjittee's
implenetaion of the SPPP, and for assessing new sources of stormwater pollution, and for 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 but is not limited to:
• require that the permittee revise, increase, or decrease monitoring frequency for some or
all parameters (analytical or qualitative);
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.

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; and
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
weather. This condition is not satisfied if adequate backup controls should have been installed in
the exercise of reasonable engineering judgment to prevent a bypass which occurred during
normal periods of equipment downtime or preventive maintenance; and
c. The permittee submitted notices as required under, Part III, Section E of this general permit.
If the Director determines that it will meet the three conditions listed above, the Director may
approve an anticipated bypass after considering its adverse effects.
SECTION D: MONITORING AND RECORDS
Representatives rnpling
Samples collected and measurements taken, as required herein, shall be characteristic of the volume
and nature of the permitted discharge. Analytical sampling shall be performed during a measureable
storm event. Samples shall be taken on a day and time that is characteristic of the discharge. All
samples shall be taken before the discharge joins or is diluted by any other waste stream, body of
water, or substance. Monitoring points as specified in this general permit shall not be changed
without notification to and approval of the Permit Issuing Authority [40 CFR 122.410)].
Recording Results
For each measurement or sample taken pursuant to the requirements of this general permit, the
permittee shall record the following information [40 CFR 122.41]:
a. The date, exact place, and time of sampling or measurements;
b. The individual(s) who performed the sampling or measurements;
PartIll Page 6 of 10

Permit No. NCG030000
c. The date(s) analyses were performed;
d. The individual(s) who performed the analyses;
e. The analytical techniques or methods used; and
f. The results of such analyses.

Where required, appropriate flow measurement devices and methods consistent with accepted
scientific practices shall be selected and used to ensure the accuracy and reliability of measurements
of the volume of monitored discharges.
4. Test Procedures
Test procedures for the analysis of pollutants shall conform to the EMC regulations published
pursuant to NCGS 143-215.63 et. seq, the Water and Air Quality Reporting Acts, and to regulations
published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as
Amended, and Regulation 40 CFR 136.
To meet the intent of the monitoring required by this general permit, all test procedures must
produce minimum detection and reporting levels and all data generated must be reported down to
the minimum detection or lower reporting level of the procedure. If no approved methods are
determined capable of achieving minimum detection and reporting levels below general permit
discharge requirements, then the most sensitive (method with the lowest possible detection and
reporting level) approved method must be used.
S. Representative Outfall
If a facility has multiple discharge locations with substantially identical stormwater discharges that
are required to be sampled, the permittee may petition the Director for representative outfall status.
If it is established that the stormwater discharges are substantially identical and the permittee is
granted representative outfall status, then sampling requirements may be performed at a reduced
number of outfalls.
Records R,gtentjQn
Qualitative monitoring shall be documented and records maintained at the facility along with the
Stormwater Pollution Prevention Plan (SPPP). Copies of analytical monitoring results shall also be
maintained on -site. The permittee shall retain records of all monitoring information, including
