Toxicity Test Procedure" (Revised- December 2010) or subsequent versions. The tests will be
performed during the months of February, May, August, and November. These months
signify the first month of each three-month toxicity testing quarter assigned to the facility.
Effluent sampling for this testing must be obtained during representative effluent discharge
and shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
If the test procedure performed as the first test of any single quarter results in a
failure or ChV below the permit limit, then multiple -concentration testing shall be
performed at a minimum, in each of the two following months as described in "North
Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -December
2010) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the

monitoring is required, the permittee will complete the information located at the top of the
aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number,
county, and the month/year of the report with the notation of "No Flow" in the comment area
of the form. The report shall be submitted to the Water Sciences Section at the address cited
above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month. Assessment of toxicity compliance is
based on the toxicity testing quarter, which is the three month time interval that begins on
the first day of the month in which toxicity testing is required by this permit and continues
until the final day of the third month.
Should any test data from this monitoring requirement or tests performed by the North
Carolina Division of Water Resources indicate potential impacts to the receiving stream, this
permit may be re -opened and modified to include alternate monitoring requirements or
limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as
minimum control organism survival, minimum control organism reproduction, and

the month of the initial monitoring.
A. (4.) 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 II
of this permit (Standard Conditions for NPDES Permits):
• Section B. Signatory Requirements
(11.)
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)]
The permittee shall report discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application.
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 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 / Water Quality Permitting Section
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 (MR 1, 1.1, 2, 3) 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 on the last day of the month
following the issuance of the permit or in the case of a new facility, on the last day of the
month following the commencement of discharge.
Page 7 of 22

DocuSign Envelope ID: 51DE46BD-29CB-4E43-84E2-AF662D5517EC
Permit NC0004944
Starting on December 21, 2025, the permittee must electronically report the following
compliance monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to
Request a Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at
the time of each electronic submission. The permittee should use the EPA's website
resources to identify the initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means
the entity (EPA or the state authorized by EPA to implement the NPDES program) that is
the designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting
tool for each type of electronic submission and for each state. Instructions on how to
access and use the appropriate electronic reporting tool will be available as well.
Information on EPA's NPDES Electronic Reporting Rule is found at:
https://www.federalregister.gov/documents/2015/ 10/22/2015-24954/national-
pollutant-discharge-elimination-system-npdes-electronic-reporting-rule
Electronic submissions must start by the dates listed in the "Reporting Requirements"
section above.
3. 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:

waters, and accurate latitude and longitude of the point(s) of discharge. The
general location map (or alternatively the site map) shall identify whether each
receiving water is impaired (on the state's 303(d) list of impaired waters) or is
located in a watershed for which a TMDL has been established, and what
the parameter(s) of concern are.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants
which could be expected to be present in the stormwater discharge from each

Permit NC0004944
(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 II, Standard Conditions,
Section B, Paragraph 11. The permittee shall re -certify annually that the
stormwater outfalls have been evaluated for the presence of non-stormwater
discharges.
(2) Stormwater Management Strategy. The stormwater management strategy shall
contain a narrative description of the materials management practices employed
which control or minimize the exposure of significant materials to stormwater,
including structural and nonstructural measures. The stormwater management
plan, at a minimum, shall incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of
changing the methods of operations and/or storage practices to eliminate or
reduce exposure of materials and processes to stormwater. Wherever practical,
the permittee shall prevent exposure of all storage areas, material handling
operations, and manufacturing or fueling operations. In areas where
elimination of exposure is not practical, the stormwater management plan shall
document the feasibility of diverting the stormwater runoff away from areas of
potential contamination.
(b) Secondary Containment Requirements and Records. Secondary
containment is required for: bulk storage of liquid materials; storage in any
amount of Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) water priority chemicals; and storage in any
amount of hazardous substances, in order to prevent leaks and spills from
contaminating stormwater runoff. A table or summary of all such tanks and
stored materials and their associated secondary containment areas shall be
maintained. If the secondary containment devices are connected to stormwater
conveyance systems, the connection shall be controlled by manually activated
valves or other similar devices (which shall be secured closed with a locking
mechanism), and any stormwater that accumulates in the containment area
shall be at a minimum visually observed for color, foam, outfall staining, visible
sheens and dry weather flow, prior to release of the accumulated stormwater.
Accumulated stormwater shall be released if found to be uncontaminated by
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. 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.

Permit NC0004944
(c) BMP Summary. A listing of site structural and non-structural Best
Management Practices (BMP) shall be provided. The installation and
implementation of BMPs shall be based on the assessment of the potential for
sources to contribute significant quantities of pollutants to stormwater
discharges and data collected through monitoring of stormwater discharges.
The BMP Summary shall include a written record of the specific rationale for
installation and implementation of the selected site BMPs. The BMP Summary
shall be reviewed and updated annually.
(3)
Spill Prevention and Response Plan. The Spill Prevention and Response Plan
(SPRP) shall incorporate an assessment of potential pollutant sources based on a
materials inventory of the facility. Facility personnel (or the team) responsible for
implementing 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. The program
shall list all stormwater control systems, stormwater discharge outfalls, all on -site
and adjacent surface waters and wetlands, industrial activity areas (including
material storage areas, material handling areas, disposal areas, process areas,
loading and unloading areas, and haul roads), all drainage features and
structures, and existing structural BMPs. The program shall establish schedules
of inspections, maintenance, and housekeeping activities of stormwater control
systems, as well as facility equipment, facility areas, and facility systems that
present a potential for stormwater exposure or stormwater pollution. Inspection
of material handling areas and regular cleaning schedules of these areas shall be
incorporated into the program. Timely compliance with the established schedules
for inspections, maintenance, and housekeeping shall be recorded in writing and
maintained in the SPPP.
(5)
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.
Facility personnel (or team) responsible for implementing the training shall be
identified, and their annual training shall be documented by the signature of each
employee trained.
(6) Responsible Party. The Stormwater Pollution Prevention Plan shall identify a
specific position(s) responsible for the overall coordination, development,
implementation, and revision to the Plan. Responsibilities for all components of
the Plan shall be documented and position assignments provided.

(7)
SPPP Amendment and Annual Update. The permittee shall amend the SPPP
whenever there is a change in design, construction, operation, or maintenance
which has a significant effect on the potential for the discharge of pollutants to
surface waters. All aspects of the Stormwater Pollution Prevention Plan shall
be reviewed and updated on an annual basis. The annual update shall include
an updated list of significant spills or leaks of pollutants for the previous three (3)
years, or the notation that no spills have occurred. The annual update shall
include written re -certification that the stormwater outfalls have been evaluated
for the presence of non-stormwater discharges. The annual update shall include a
documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Strategy. The annual update shall also
include a review and comparison of sample analytical data to benchmark values
over the past year, including a discussion about Tiered Response status.
The Director may notify the permittee when the Plan does not meet one or more of
the minimum requirements of the permit. Within 30 days of such notice, the
permittee shall submit a time schedule to the Director for modifying the Plan to
meet minimum requirements. The permittee shall provide certification in writing
(in accordance with Part II, Standard Conditions, Section B, Paragraph 11 to the
Director that the changes have been made.
(8) Facility Inspections. Inspections of the facility and all stormwater systems shall
occur as part of the Preventative Maintenance and Good Housekeeping Program at
a minimum on a semi-annual schedule, once during the first half of the year
(January to June), and once during the second half (July to December), with at
least 60 days separating inspection dates (unless performed more frequently than
semi-annually). These facility inspections are different from, and in addition to,
the stormwater discharge characteristic monitoring required in Section B. 1. b) (8)
- Qualitative Monitoring below.
(9)
SPPP Implementation. The permittee shall implement the Plan. Implementation
of the Plan shall include documentation of all monitoring, measurements,
inspections, maintenance activities, and training provided to employees, including
the log of the sampling data and of actions taken to implement BMPs associated
with the industrial activities, including vehicle maintenance activities. Such
documentation shall be kept on -site for a period of five years and made available
to the Director or the Director's authorized representative immediately upon
request.
b) MINIMUM MONITORING AND REPORTING REQUIREMENTS
(1) Analytical monitoring of stormwater discharges shall be performed as specified
in Table 1. All samples shall be collected from a discharge resulting from a
measureable storm event. The required monitoring will result in a minimum of
six (6) analytical samplings being conducted over the term of the permit at each
stormwater discharge outfall (SDO).
Page 13 of 22

DocuSign Envelope ID: 51 DE46BD-29CB-4E43-84E2-AF662D5517EC
Permit NC0004944
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 Regional Office
Supervisor.
(2) If the stormwater is controlled by a detention pond, and that pond discharges only
in response to a storm event exceeding a 25-year, 24-hour storm, the pond shall be
considered a non -discharging stormwater control system and not subject to NPDES
requirements, unless the discharge causes a violation of water quality standards.
(3)
Stormwater samples analyzed in accordance with the terms of this permit shall be
submitted on forms provided by the Director. The permittee must report the
results from all samples taken within the monitoring period as specified in the
Standard Conditions of this permit, and as supplemented or superseded by
electronic DMR reporting requirements in Part I, Section A(4.). 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.
(4) Specific monitoring requirements:

2 If the stormwater runoff is controlled by a stormwater detention pond a grab sample of the
discharge from the pond shall be collected within the first 30 minutes of discharge from the
pond.
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.
Monitoring results shall be compared to the benchmark values in Table 4. The
benchmark values in Table 4 are not permit limits but should be used as guidelines
for the permittee's 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), as provided in 3. below.
(5) The permittee shall report the analytical results from each sample within the
monitoring period. The permittee shall compare monitoring results to the
benchmark values in Table 4. The benchmark values in Table 4 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 permittee to
increase monitoring, increase management actions, increase record keeping,

Permit NC0004944
Tier Two
If: During the term of this permit, the first valid sampling results from two consecutive
monitoring periods 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 for all parameters 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 the
benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to
record "No Flow" on a monthly monitoring report to comply with reporting
requirements.
4. Maintain a record of the Tier Two response in the Stormwater Pollution Prevention
Plan.
During the term of this permit, 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 DWR Regional Office Supervisor in writing within 30 days of receipt of the
fourth analytical results. DWR may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency for
the remainder of the permit;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures; or
• require that the permittee implement site modifications to qualify for the No
Exposure Exclusion.
(6) If a facility is required to sample multiple stormwater discharge locations, the
permittee may petition the Director to sample at a reduced number of outfalls.
These outfalls would be granted "Representative Outfall Status" (ROS). DWR may
grant Representative Outfall Status if discharges from a single outfall are
representative of discharges from multiple outfalls. Approved ROS will reduce the
number of outfalls where analytical sampling requirements apply. Qualitative
observations shall be recorded for all outfall locations.
(7) This site discharges to impaired waters experiencing problems with nutrient
loading (High Rock Lake watershed). If a Total Maximum Daily Load (TMDL) is
approved for this segment of North Second Creek or High Rock Lake, the permittee
may be required to monitor for the pollutant(s) of concern in the future and submit
results to the Division of Water Resources. The Division will consider the
monitoring results in determining whether additional BMPs are needed to control
the pollutant(s) of concern to the maximum extent practicable.

If additional BMPs are needed to achieve the required level of control, the permittee
will be required to (1) develop a strategy for implementing appropriate BMPs, and
(2) submit a timetable for incorporation of those BMPs into the permitted
Stormwater Pollution Prevention Plan.
(8) Qualitative monitoring requires a visual inspection of each stormwater outfall
regardless of representative outfall status and shall be performed as specified in
Table 5, during the analytical monitoring event. [If analytical monitoring is not
required, the permittee still must conduct semi-annual qualitative monitoring.]
Qualitative monitoring is for the purpose of evaluating the effectiveness of the
Stormwater Pollution Prevention Plan (SPPP) and assessing new sources of
stormwater pollution.

Permit NC0004944
permittee shall submit forms and fees as are required by the agency authorized to
issue permits no later than 180 days prior to the expiration date, unless permission
for a later date has been granted by the Director. (The Director shall not grant
permission for applications to be submitted later than the expiration date of the
existing permit) [40 CFR 122.21(d)]. The permittee must apply separately to the
North Carolina Division of Energy, Mineral, and Land Resources (DEMLR)
Stormwater Program for a separate NPDES Stormwater Discharge Permit no later
than June 3, 2022.
d) RECORDS RETENTION
Along with the Stormwater Pollution Prevention Plan (SPPP), qualitative monitoring
shall be documented and records maintained at the facility. Copies of analytical
monitoring results shall also be maintained on -site. The permittee shall retain records
of all monitoring information, including all calibration and maintenance records and
all original strip chart recordings for continuous monitoring instrumentation, and
copies of all reports required by this individual permit for a period of at least 5 years
from the date of the sample, measurement, report or application. This period may be
extended by request of the Director at any time.
d) BYPASSING OF STORMWATER CONTROL FACILITIES
Bypass is prohibited, and the Director may take enforcement action against a
permittee for bypass unless:
(1) The bypass was unavoidable to prevent loss of life, personal injury or severe
property damage; and
(2) 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
(3) The permittee submitted notices as required under, Part III, Section C 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.
e) Stormwater Definitions
(1) Adverse Weather
Adverse conditions are those that are dangerous or create inaccessibility for
personnel, such as local flooding, high winds, or electrical storms, or situations that
otherwise make sampling impractical. When adverse weather conditions prevent the
collection of samples during the sample period, the permittee must take a substitute
sample or perform a visual assessment during the next qualifying storm event.
Documentation of an adverse event (with date, time and written narrative) and the
rationale must be included with SPPP records. Adverse weather does not exempt the
permittee from having to file a monitoring report in accordance with the sampling
Page 19 of 22

DocuSign Envelope ID: 51DE46BD-29CB-4E43-84E2-AF662D5517EC
Permit NC0004944
schedule. Adverse events and failures to monitor must also be explained and
reported on the relevant DMR.
(2) Best Management Practices (BMPs1
Measures or practices used to reduce the amount of pollution entering surface
waters. BMPs may take the form of a process, activity, or physical structure. More
information on BMPs can be found at: http://www.epa.gov/npdes/national-menu-
best-management-practices-bmps-stormwater#edu.
(3)
Bulk Storage of Liquid Products
Liquid raw materials, manufactured products, waste materials or by-products with
a single above ground storage container having a capacity of greater than 660 gallons
or with multiple above ground storage containers having a total storage capacity of
greater than 1,320 gallons.
(4) Municipal Separate Storm Sewer System (MS4)
A stormwater collection system within an incorporated area of local self-
government such as a city or town.
(5) No Exposure
A condition of no exposure means that all industrial materials and activities are
protected by a storm resistant shelter or acceptable storage containers to prevent
exposure to rain, snow, snowmelt, or runoff. Industrial materials or activities
include, but are not limited to, material handling equipment or activities, industrial
machinery, raw materials, intermediate products, by-products, final products, or
waste products. DWR may grant a No Exposure Exclusion from NPDES
Stormwater Permitting requirements only if a facility complies with the terms and
conditions described in 40 CFR §122.26(g)
(6) Measureable Storm Event
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 may not apply if the permittee is able to document that a
shorter interval is representative for local storm events during the sampling period,
and obtains approval from the local Regional Office Supervisor in writing.
(7)
Point Source Discharge of Stormwater
Any discernible, confined and discrete conveyance, including but specifically not
limited to, any pipe, ditch, channel, tunnel, conduit, well, discrete fissure,
container, rolling stock, or concentrated animal feeding operation from which
pollutants are or may be discharged via stormwater to waters of the state.
(8) Representative Outfall Status
When it is established that the discharge of stormwater runoff from a single outfall
is representative of the discharges at multiple outfalls, the DWR may grant
representative outfall status. Representative outfall status allows the permittee to
perform analytical monitoring at a reduced number of outfalls.
(9)
Secondary Containment
Spill containment for the contents of the single largest tank within the containment
structure plus sufficient freeboard to allow for the 25-year, 24-hour storm event.

2/Month
Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall be
representative of the wastewater discharged during the sample period.
3/Week
Samples are collected three times per week on three separate calendar days. These samples shall be representative of
the wastewater discharged during the sample period.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et.
seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which is
not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Week

Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval
between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite
samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period
of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with
the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow
measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the

(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a
constant time interval. Use of this method requires prior approval by the Director. This method may only be
used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply:
➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
➢ Influent samples shall not be collected more than once per hour.
➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab

grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling
period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample," above.)

action against a Permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities,
retention of untreated wastes or maintenance during normal periods of equipment downtime. This
condition is not satisfied if adequate backup equipment 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 Paragraph b. of this section.
(2) Bypass from the collection system is prohibited and the Permit Issuing Authority may take enforcement
action against a Permittee for a bypass as provided in any current or future system -wide collection system
permit associated with the treatment facility.

noncompliance with such technology based permit effluent limitations if the requirements of paragraph b. 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 Permittee facility was at the time being properly operated; and
(3) The Permittee submitted notice of the upset as required in Part II.E.6.(b) of this permit.
(4) The Permittee complied with any remedial measures required under Part II.B.2. of this permit.

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and (j) and 15A NCAC 02H .0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.

(8) Any trucked or hauled pollutants, except at discharge points designated by the POTW.
c. The Permittee shall investigate the source of all discharges into the POTW, including slug loads and other
unusual discharges, which have the potential to adversely impact the Permittee's Pretreatment Program and/or
the operation of the POTW.
The Permittee shall report such discharges into the POTW to the Director or the appropriate Regional Office.
Any information shall be provided orally within 24 hours from the time the Permittee became aware of the
circumstances. A written submission shall also be provided within 5 days of the time the Permittee becomes
aware of the circumstances. The written submission shall contain a description of the discharge; the
investigation into possible sources; the period of the discharge, including exact dates and times; if the
discharge has not ceased, the anticipated time it is expected to continue; and steps taken or planned to reduce,
eliminate, and prevent reoccurrence of the noncompliance,
All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:
1. Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of
transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
