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 Energy, Mineral, and Land Resources (DEMLR) 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until the individual permit has expired or has been revoked.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 the Division 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 Plan, as outlined in the Stormwater Pollution
Prevention Plan, Part II, Section A. A list of approved TMDLs for the state of North Carolina can be
found at https:/Ideq.nc.govlabout/divisions/water-resources/planning/modeling-
assessment/tmdls/draft-and-approved-tmdls.

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 and the requirements of the permittee's Certificate of Coverage (COC). The
permittee's COC is hereby incorporated by reference into this General Permit. Any violation
of the COC is a violation of this General Permit and subject to enforcement action as provided
in the 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 allowed by this permit must meet applicable wetland
standards as outlined in 15A NCAC 213.0230 and .0231 and water quality certification requirements
as outlined in 15A NCAC 2H .0500.
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:
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 III,
Standard Conditions, Section B, Paragraph S.
Page 3 of 30

Permit No. NCG030000
2. Stormwater Management Strategy. The Stormwater Management Strategy shall contain a
narrative description of the materials management practices employed which control or
minimize the stormwater exposure of significant materials, including structural and
nonstructural measures. The Stormwater Management Strategy, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing the
methods of operations and/or storage practices to eliminate or reduce exposure of
materials and processes to rainfall and run-on flows. Wherever practical, the permittee
shall prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is not
practical, this review shall document the feasibility of diverting the stormwater run-on
away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials including petroleum products; storage in au
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.
i. A table or summary of all such tanks and stored materials and their associated
secondary containment areas shall be maintained.
ii. 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 securely closed with a locking mechanism).
iii. 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.
iv. Accumulated stormwater shall be released if found to be uncontaminated by any
material.
v. Records documenting the individual making the observation, the description of the
accumulated stormwater, and the date and time of the release shall be kept for a
period of five (5) years.
For facilities subject to a federal oil Spill Prevention, Control, and Countermeasure Plan
(SPCC), any portion of the SPCC plan fully compliant with the requirements of this permit
may be used to demonstrate compliance with this permit. The Division may allow
exceptions to secondary containment requirements for mobile refuelers, as with the
exemption provided by amendments to federal SPCC regulations, as long as appropriate
spill containment and/or diversionary structures or equipment is used to prevent discharge
to surface waters. Exceptions do not apply to refuelers or other mobile tankage used
primarily as bulk liquid material storage in a fixed location in place of stationary containers.
(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.
Page 4 of 30

Permit No. NCG030000
3. Spill Prevention and Response Procedures. The Spill Prevention and Response Procedures
(SPRP) shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel responsible for implementing the SPRP shall be
identified in a written list incorporated into the SPRP and signed and dated by each individual
acknowledging their responsibilities for the plan. A responsible person shall be on -site at all
times during facility operations that have 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 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.
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, 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 personnel responsible for
implementing the training shall be identified, and their annual training shall be documented by
the signature of each employee trained.
7. Responsible Party. The SPPP shall identify a specific position or positions responsible for the
overall coordination, development, implementation, and revision of the SPPP. Responsibilities
for all components of the SPPP shall be documented and position assignments provided.
8. SPPP Amendment and Annual Update. The permittee shall amend the SPPP whenever there
is a change in design, construction, operation, site drainage, maintenance, or configuration of
the physical features which may have a significant effect on the potential for the discharge of
pollutants to surface waters. All aspects of the SPPP shall be reviewed and updated on an
annual basis. The annual update shall include:
Page 5 of 30

Permit No. NCG030000
(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 pastyear;
(e) a statement that the Solvent Management Plan (if applicable) has an updated
inventory of total toxic organic compounds;
(f) 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:
https://deq.nc.gov/about/divisions/energy-mineral-land-resources/npdes-
stormwater-gps).
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 5) 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 (5) 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 II, 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.
DEQ 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 requirement for total toxic organics
(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."

Permit No. NCG030000
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a measurable storm event at each stormwater
discharge outfall (SDO). Only SDOs discharging stormwater associated with industrial activity must
be sampled (See Definitions).
A measurable storm event is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a
shorter interval is representative for local storm events during the sampling period, and the
permittee obtains approval from the local DEMLR Regional Office. See Definitions.
The permittee shall compare monitoring results to the benchmark values in Table 1. Exceedances
of benchmark values require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install Stormwater Control Measures (SCM) in a tiered program.
See below for the descriptions of Tier One, Tier Two, and Tier Three response actions below. In
the event that the Division releases the permittee from continued monthly monitoring and
reporting under Tiers Two or Three, the Division's release letter may remain in effect through
subsequent reissuance of this permit, unless the release letter provides for other conditions or
duration.
The benchmark values in Table 1 are not permit limits but should be used as guidelines for
implementation of the permittee's SPPP. An exceedance of a stormwater benchmark value is not a
permit violation; however, failure to respond to the exceedance as outlined in this permit is a
violation of permit conditions.
Please note that the parameter in the last row of Table 1 (New Motor Oil or Hydraulic Oil Usage) is
only required for outfalls that discharge runoff from vehicle or equipment maintenance areas in
which more than 55 gallons of new motor oil and/or hydraulic oil are used per month when
averaged over the calendar year.

Footnotes:
1 Measurement Frequency: Twice per year during a measureable storm event (unless other provisions of
the permit prompt monthly sampling), until either another permit is issued for this facility or until this
permit is revoked or rescinded. See Table 2 for schedule of monitoring periods through the end of this
permitting cycle. If the facility is monitoring monthly because of Tier Two or Three response actions
under the previous permit, the facility shall continue a monthly monitoring and reporting schedule in
Tier Two or Tier Three status until relieved by the provisions of this permit or the Division.
2 Grab samples shall be collected within the first 30 minutes of discharge. When physical separation
between outfalls prevents collecting all samples within the first 30 minutes, sampling shall be begun within
the first 30 minutes, and shall continue until completed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted. A copy of the letter granting ROS shall be kept on
site.
4 For each sampled measureable storm event the total precipitation must be recorded. An on -site rain
gauge is required. Where isolated sites are unmanned for extended periods of time, a local rain gauge may
be substituted for an on -site reading.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing
operation, manufacture semiconductors, manufacture electronic crystals, or manufacture cathode ray
tubes. For purposes of this permit the definition of TTO is that definition contained in the EPA Effluent
Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as
found in 40 CFR 433.11; for semiconductor manufacture use the definition as found in 40 CFR 469.12; for
electronic crystal manufacture use the 40 CFR 469.22; and for cathode ray tube manufacture use the
definition found in 40 CFR 469.31.)
6 If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation
pH levels are lower, then the lower threshold of this benchmark range is the pH of the precipitation
instead of 6 standard units. Readings from an on -site or local rain gauge must be documented to
demonstrate background concentrations were below the benchmark pH range.
The permittee shall complete the analytical samplings in accordance with the schedule specified
below in Table 2, unless adverse weather conditions prevent sample collection (see Adverse
Weather in Definitions). A minimum of 60 days must separate Period 1 and Period 2 sample
dates, unless monthly monitoring has been instituted as part of other requirements of this permit.
Inability to sample because of adverse weather conditions must be documented in the SPPP and
recorded on the DMR. The permittee must report the results from each sample taken within the
monitoring period (see Part III, Section E). However, for purposes of benchmark comparison and
Tiered response actions, the permittee shall use the analytical results from the first sample with
valid results within the monitoring period.

Footnotes:
1. Maintain semi-annual monitoring during the General Permit renewal process (unless other provisions of
this permit require monthly sampling). The applicant must continue monitoring until the renewed
Certificate of Coverage (COC) is issued.
2. If no discharge occurs during the sampling period, the permittee must record "No Flow" or "No
Discharge" within 30 days of the end of the sampling period.
3. Monitoring periods remain constant throughout the five-year term of the General Permit. For permittees
continuing with renewed coverage under this General Permit, Year 1 begins in Period 1 on January 1,
2019, and for all permittees, Year 5 ends in Period 2 on October 31, 2023.
Failure to monitor semi-annually per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period. "No discharge" from an outfall 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.
Tier One
If: The first valid sampling results are above a benchmark value, or outside of the benchmark range, for any
parameter at any outfall;
Then: The permittee shall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving sampling
results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential, and select the specific feasible: source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern, and/or to bring concentrations
within the benchmark range.
4. Implement the selected feasible actions within two months of the inspection.
S. Record each instance of a Tier One response in the SPPP. Include the date and value of the benchmark
exceedance, the inspection date, the personnel conducting the inspection, the selected actions, and the date
the selected actions were implemented.
6. Note: Benchmark exceedances for a different parameter separately trigger a tiered response.
Page 9 of 30

Permit No. NCG030000
Tier Two
If. The first valid sampling results from two consecutive monitoring periods (omitting periods with no discharge)
are above the benchmark values, or outside of the benchmark range, for any specific parameter at a specific
discharge outfall;
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow" to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, exercise the
option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional Engineer
may direct the response actions on the part of the permittee as provided in Tier Three, including reduced or
additional sampling parameters or frequency.
5. Maintain a record of the Tier Two response in the SPPP.
6. Continue Tier Two response obligations throughout the permit renewal process.
Tier Three
If. The valid sampling results required for the permit monitoring periods exceed the benchmark value, or are
outside the benchmark range, for any specific parameter at any specific outfall on four occasions, the permittee
shall notify the DEMLR Regional Engineer in writing within 30 days of receipt of the fourth analytical results;
Then: The Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring and reporting frequency for some
or all of the parameters herein;
• require sampling of additional or substitute parameters;
• require the permittee to install structural stormwater control measures;
• require the permittee to implement other best management practices;
• require the permittee to perform upstream and downstream monitoring to characterize impacts on
receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion;
• require the permittee to continue Tier Three obligations through the permit renewal process.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and 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 3, and during required analytical monitoring events if applicable (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 and recorded on the DMR (see Adverse Weather in Definitions). Only SDOs discharging
stormwater associated with industrial activity must be monitored (See Definitions).

1 Measurement Frequency: Twice per year (unless other provisions of this permit prompt monthly
sampling) during a measureable storm event. See Table 2 for schedule of monitoring periods. The
permittee must continue qualitative monitoring throughout the permit renewal process.
2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(SDO) associated with industrial activity, regardless of representative outfall status.
A minimum of 60 days must separate monitoring dates, unless additional sampling has been
instituted as part of other analytical monitoring requirements in this permit.
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are ineffective, or
that significant stormwater contamination is present, the permittee shall investigate potential
causes, evaluate the feasibility of corrective actions, and implement those corrective actions within
60 days, per the Qualitative Monitoring Response, below. A written record of the permittee's
investigation, evaluation, and response actions shall be kept in the Stormwater Pollution Prevention
Plan.
Qualitative Monitoring Response
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, 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, DEMLR 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 control measures;
• require the permittee to implement other best management practices;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.

SECTION D: SPECIAL CONDITIONS
A (1.) ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on
December 21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part III of
this permit (Standard Conditions for NPDES Permits):
• Section B. (5.) Signatory Requirements
• Section D. (6.) Records Retention
• Section E. (1.) Discharge Monitoring Reports
• Section E. (2.) Submitting Reports
1. Reporting Requirements [Supplements Section E. (1.) and Supersedes Section E.
L)
Effective December 21, 2016 or when the agency's electronic reporting system is able to
accept NPDES stormwater permit monitoring data, the permittee shall report discharge
monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report
(eDMR) internet application. NC DEMLR will notify permittees when eDMR is ready to accept
stormwater monitoring data.
Monitoring results obtained during the previous month(s) shall be summarized for each month
and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the
state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and also will be required to complete the eDMR submission by
printing, signing, and submitting one signed original and a copy of the computer printed eDMR
to the following address:
NC DEQ / Division of Water Resources
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements
may be granted and discharge monitoring data may be submitted on paper DMR forms or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above. See "How to Request a Waiver from Electronic Reporting" section
below.
Regardless of the submission method, the first DMR is due no later than 30 days from the
date the facility receives the sampling results from the laboratory.

Permit No. NCG030000
2. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain
an electronic reporting waiver, a permittee must first submit an electronic reporting waiver
request to the Division. Requests for temporary electronic reporting waivers must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the
date the facility would be required under this permit to begin submitting monitoring data and
reports. The duration of a temporary waiver shall not exceed 5 years and shall thereupon
expire. At such time, monitoring data and reports shall be submitted electronically to the
Division unless the permittee re -applies for and is granted a new temporary electronic
reporting waiver by the Division. Approved electronic reporting waivers are not transferrable.
Only permittees with an approved reporting waiver request may submit monitoring data and
reports on paper to the Division for the period that the approved reporting waiver request is
effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found
on the following web page:

Permit No. NCG030000
SECTION C: OPERATION AND MAINTENANCE OF POLLUTION CONTROLS
1. Proper Operation and Maintenance
The permittee shall at all times properly operate and maintain all facilities and systems of
treatment and control (and related appurtenances) which are installed or used by the
permittee to achieve compliance with the conditions of this permit. Proper operation and
maintenance also includes adequate laboratory controls and appropriate quality assurance
procedures. This provision requires the operation of back-up or auxiliary facilities or
similar systems which are installed by a permittee only when the operation is necessary to
achieve compliance with the conditions of this permit. [40 CFR 122.41(e)]
2. Need to Halt or Reduce Not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been
necessary to halt or reduce the permitted activity in order to maintain compliance with the
condition of this general permit. [40 CFR 122.41(c)]
Bypassing of Stormwater Control Facilities
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.
4. Upsets
a. Effect of an upset [40 CFR 122.41(n)(2)]: An upset constitutes an affirmative defense to
an action brought for excursion from permit benchmark concentrations and/or
noncompliance with monitoring requirements if the requirements of this condition are
met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
b. Conditions necessary for a demonstration of upset: Any Permittee who wishes to
establish the affirmative defense of upset shall demonstrate, through properly signed,
contemporaneous operating logs, or other relevant evidence that:
(1) An upset occurred and that the Permittee can identify the cause(s) of the upset;
(2) The Permitted facility was at the time being properly operated;
(3) The Permittee submitted notice of the upset as required in Part III, Section E, Item
(9) of this general permit; and
(4) The Permittee complied with any remedial measures required Part III, Section E,
Item (9) of this permit.
Page 21 of 30

Permit No. NCG030000
c. Burden of proof [40 CFR 122.41(n)(4)]: The Permittee seeking to establish the
occurrence of an upset has the burden of proof in any enforcement proceeding.
SECTION D: MONITORING AND RECORDS
Representative Sampling
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 122.41(j)]
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;
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.
Flow Measurements
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 143-21S.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.
Representative Outfall
