PART I INTRODUCTION
SECTION A: INDIVIDUAL PERMIT COVERAGE
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.
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 Certification from NPDES
stormwater discharge permit requirements. Any owner or operator wishing to obtain a No
Exposure Certification must:
• Submit a No Exposure Certification application form to the Division of Energy,
Mineral and Land Resources (Division)
• Receive approval from the Division,
• Maintain no exposure conditions unless authorized to discharge under a valid
NPDES stormwater permit, and
• Recertify the No Exposure Certification annually.
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 that
has been adequately treated and managed in accordance with the terms and 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 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 (SWPPP)
The permittee shall develop and implement a Stormwater Pollution Prevention Plan
(SWPPP). The SWPPP shall be maintained on site unless exempted from this requirement
by the Division. The SWPPP is public information in accordance with Part III, Standard
Conditions, Section E, paragraph 3 of this permit. The SWPPP 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:
i. the facility's location in relation to transportation routes and surface
waters; and
ii. 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.
The general location 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:
i. The site property boundary;
ii. Site topography and finished grade;
iii. Buildings;
iv. Industrial activity areas (including storage of materials, disposal areas,
process areas, loading and unloading areas, and haul roads);
v. Stormwater discharge outfalls (latitudes and longitudes must be listed);
vi. Drainage area for each outfall;
vii. Direction of flow in each drainage area;
viii. All on -site and adjacent surface waters and wetlands;
ix. All drainage features and structures;
x. Stormwater Control Measures (SCMs);
xi. Stormwater Best Management Practices (BMPs); and
xii. Impervious surfaces.
Page 3 of 30

Permit No. NCS000514
Additionally, the site map must indicate the percentage of each drainage area that is
impervious. A graphic scale and north arrow are also required components.
(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 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. 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; 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.
a. Specific Controls
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 maintained in the
closed position and secured closed with a locking mechanism.
b. Inspections
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, and said observations shall be documented
prior to release of the accumulated stormwater. Accumulated
stormwater may be released if found to be uncontaminated by any
Page 4 of 30

Permit No. NCSOOOS 14
material. Accumulated stormwater found to be contaminated shall not be
released from the containment area. Documentation shall include the
individual making the observation, the description of the accumulated
stormwater and observations, and the method, date and time of the
release or disposal.
C. Exceptions
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) SCM/BMP Summary. A listing of structural Stormwater Control Measures (SCM)
and non-structural Best Management Practices (BMPs) on site shall be provided.
The installation and implementation of SCMs and/or 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 SCM/BMP Summary shall include a written record of
the specific rationale for installation and implementation of the selected site SCMs
and/or BMPs. The SCM/BMP Summary shall be reviewed 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. 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
increased 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
Page 5 of 30

Permit No. NCS000514
structures, and existing structural SCMs and non-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 SWPPP. 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
SWPPP.
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 II B and C of this
permit.
6. Employee Training. Training programs addressing spill response and cleanup
procedures, preventative maintenance and good housekeeping activities, and facility
inspections 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 SWPPP shall identify a specific position or positions
responsible for the overall coordination, development, implementation, and revision of
the SWPPP. Responsibilities for all components of the SWPPP shall be documented and
position assignments provided.
8. SWPPP Amendment and Annual Update. The permittee shall amend the SWPPP
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 SWPPP shall be 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;
(b) A written certification that the stormwater outfalls have been evaluated for
the presence of non-stormwater discharges;
(c) A documented re-evaluation of the effectiveness of the on -site SCMs and
BMPs in minimizing the contamination of stormwater runoff, including a
Page 6 of 30

Permit No. NCS000514
summarization of all SCM inspections conducted throughout the year
preceding the annual update;
(d) A statement that annual training requirements were met in the past year;
and
(e) A review and comparison of sample analytical data to benchmark values (if
applicable) over the past year, including an evaluation of Tiered Response
status. The permittee shall use the Division's Generic Annual Data
Monitoring Report (DMR) Form, available from the Stormwater Permitting
Program's website (See: https://deq.nc.g_ov/about/divisions/energy-
mineral-land-resources/npdes-stormwater-individual).
The Director may notify the permittee when the SWPPP 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 SWPPP 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. SWPPP Implementation. The permittee shall implement the SWPPP and all
appropriate SCMs and BMPs consistent with the provisions of this permit, in order to
control contaminants entering surface waters via stormwater. Implementation of the
SWPPP 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 SCMs and 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 Division
immediately upon request.
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 Engineer. 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 SCMs and BMPs in a tiered
program. See the descriptions of Tier One, Tier Two, and Tier Three response actions below
in Table 3, Table 4, and Table 5.
Page 7 of 30

Permit No. NCS000514
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.
In the event that the Division releases the permittee from continued monthly monitoring and
reporting under Tier Two or Tier 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. If the permittee obtains a written release letter from the Division
which approves modification of Tier 2 or Tier 3 monitoring requirements, then the letter shall
become an enforceable component of this permit.
The benchmark values in Table 1 are not permit limits but shall be used as guidelines for
implementation and evaluation of the permittee's SWPPP. 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 parameters in the last two rows in Table 1 (non -polar oil and grease
and new motor/hydraulic oil usage) are 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 (unless other provisions of this permit prompt monthly
sampling) during a measurable storm event, until either another permit is issued for this facility or
until this permit is revoked or rescinded. 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 begin within
the first 30 minutes, and shall continue until completed.
Page 8 of 30

Permit No. NCSOOOS14
Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted. A copy of the Division's letter granting ROS shall
be kept on site.
For each sampled measurable 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
reading may be substituted for an on -site reading.
This parameter is only required for outfalls that discharge runoff from vehicle / equipment maintenance
areas in which more than 55 gallons of new motor oil or hydraulic oil per month is used when
averaged over the calendar year.
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). Sampling is not required outside of the facility's
normal operating hours. A minimum of 60 days must separate Period Land Period 2
sample dates, unless monthly monitoring has been instituted under a "Tier Two"
response. Inability to sample because of adverse weather conditions must be documented
in the SWPPP 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 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" or "No Discharge" within 30 days of the end of the sampling period.
3 Monitoring periods remain consistent through the permit term and through the renewal process. The
first sampling period begins in Period 2 on July 1, 2020.
Failure to monitor semi-annually per permit conditions may result in the Division
requiring monthly monitoring for all parameters for a specified time period. "No
discharge" from an outfall during a monitoring period does not constitute failure to
monitor, as long as it is properly recorded and reported.

ranee 3. ner une xeouirements
If any parameter at any outfall is above a benchmark value, or outside of the benchmark range, for the first valid
sampling results;
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. Evaluate and select specific source controls, operational controls, and/or physical improvements to
reduce concentrations of the parameter(s) of concern and bring concentrations within the benchmark
range.
4. Implement the selected controls/improvements within two months of the inspection.
S. Record each instance of a Tier One response in the SWPPP. 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.
Note: A benchmark exceedance triggers a Tier One response for each parameter.
1dU1C `k. 11C1- 1 WU 1<CUUll-C111C111J
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
Then the permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all analytical monitoring 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.
S. Maintain a record of the Tier Two response in the SWPPP.
6. Continue Tier Two response obligations throughout the permit renewal process.

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, at minimum, require the permittee:
• Revise, increase, or decrease the monitoring and reporting frequency for some or all of the parameters
herein;
• Sampling of additional or substitute parameters;
• Install structural stormwater controls;
• Implement other stormwater control measures;
• Perform upstream and downstream monitoring to characterize impacts on receiving waters;
• Implement site modifications to qualify for a No Exposure Exclusion;
• Continue Tier Three obligations through the permit renewal process.
This site discharges to impaired waters experiencing problems with fish tissue mercury. If
the Division institutes further actions, which may include the development of a Total
Maximum Daily Load (TMDL) for this segment of South Stanley Creek, then the Division
will consider your monitoring results in determining whether additional SCMs and/or
BMPs are needed to control the pollutant(s) of concern to the maximum extent practicable.
If additional SCMs and/or BMPs are needed to achieve the required level of control, the
permittee will be notified in writing and required to (1) develop a strategy for
implementing appropriate SCMs and/or BMPs, and (2) submit a timetable for
incorporation of those SCMs and/or BMPs into the SWPPP.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the SWPPP and
identify new potential 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
during required analytical monitoring events (unless the permittee is required to perform
further qualitative monitoring per the Qualitative Monitoring Response, below). Inability
to monitor because of adverse weather conditions must be documented in the SWPPP and
recorded on the Qualitative Monitoring Report form (see Adverse Weather in Definitions).
Only SDOs discharging stormwater associated with industrial activity must be monitored
(See Definitions).
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee
shall document the suspected cause of the condition and any actions taken in response to.
the discovery. This documentation shall be maintained with the SWPPP.

Footnotes:
1 Monitoring Frequency: Twice per year during a measurable storm event unless other provisions of this
permit prompt monthly monitoring. See Table 2 for schedule of monitoring periods. The permittee must
continue qualitative monitoring throughout the permit renewal process until a new permit is issued.
2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(SDO) 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 SCMs and/or
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 in Table 7. A written record of the permittee's investigation, evaluation, and
response actions shall be kept in the SWPPP.
'able 7. Qualitative Monitoring Response
Qualitative monitoring is for the purposes of evaluating SWPPP effectiveness, identifying new
potential 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, then the
Division may, at minimum, require the permittee:
• Revise, increase, or decrease the monitoring frequency for some or all parameters
(analytical or qualitative);
• Install structural stormwater controls;
• Implement other stormwater control measures;
• Perform upstream and downstream monitoring to characterize impacts on receiving
waters; or
• Implement site modifications to qualify for a No Exposure Exclusion.

SECTION D: SPECIAL CONDITIONS
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. (3.) 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. (2.)]
Until the Division initiates electronic Discharge Monitoring Reports (eDMRs), DMRs
shall be submitted to the Division using the following process:
1. Print a blank copy of the DMR form from the NPDES Stormwater Individual
Permits web site at https://Ideq.nc.gov/about/divisions/energy-mineral-land-
resources/npdes-stormwater-individual.
2. Complete, sign and scan the DMR Form and submit it using the Digital
Submittal Form on the NPDES Stormwater Individual Permits web site at

stormwater-individual.
3. Mail the original, signed DMR form to the following address:
DEMLR Mooresville Regional Office
610 East Center Avenue, Suite 301
Mooresville, NC 28115
The Division shall notify NPDES Individual Industrial facilities when the eDMR system
is able to accept NPDES stormwater permit monitoring data. Upon initiation of the
stormwater eDMR system for Individual Industrial facilities, the permittee shall report
discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report (eDMR) internet application. The Division will notify permittees
when eDMR is ready to accept stormwater monitoring data.
After eDMR is initiated, 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
fewer than 10 percent of the households have broadband access, then the Director may
grant a temporary waiver from electronic reporting requirements may be granted and
Page 13 of 30

Permit No. NCS000514
discharge monitoring data may be submitted on paper DMR forms or alternative forms.
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.
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:
http:./-/deq..nc.gov/about/divisions/water-resources/edmr

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)].
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 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 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.

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 demonstration of upset: Any Permittee who wishes to
establish the affirmative defense of upset shall demonstrate, through properly signed,
contemporaneous operation logs, or other relevant evidence that:
(1) An upset occurred and that the Permittee can identify the causes) of the upset;
(2) The Permitted facility was at the time being properly operated;
(3) The Permittee submitted notice of the upset; and

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 measurable 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 permit shall not be changed without notification to and approval of the
Permit Issuing Authority [40 CFR 122.41(j)].
2. Recording Results
For each measurement or sample taken pursuant to the requirements of this 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.

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 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. 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.
6. Records Retention
Visual monitoring shall be documented, and records maintained at the facility along with
the Stormwater Pollution Prevention Plan. Copies of analytical monitoring results shall also
Page 22 of 30
