Dear Mr. Cox:
Director
Division personnel have reviewed and approved your application for renewal of the subject
permit. Accordingly, we are forwarding the attached NPDES permit. This permit is issued
pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum
of Agreement between North Carolina and the U.S. Environmental Protection Agency dated
October 15, 2007 (or as subsequently amended).
At the next renewal you will be required to submit a separate stormwater permit application
and obtain a separate stormwater permit. [See Special Condition A. (24.)]. In regards to Division
approval to continue constant time -based composite sampling at Outfalls 002 and 003, in this case,
constant time -based composite sampling is appropriate and approved.
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. The requirement to begin reporting discharge monitoring
data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet
application has been added to your final NPDES permit. [See Special Condition A. (14.)].
For information on eDMR, registering for eDMR and obtaining an eDMR user account,

1. Submit Discharge Monitoring Reports electronically using NC DWR's eDMR application system. See Special
Condition A. (14.).
2. TN Load is the mass quantity of TN discharged in a given period of time. See Special Condition A. (5.).
3. Sample locations: S1- Chlorine contact chamber or other approved location; Upstream, approximately 100 yard
above outfall; Downstream, approximately 1 mile below outfall. Instream monitoring requirements for Fecal
Coliform, Dissolved Oxygen, and Temperature are waived as along as Permittee maintains membership in the
Lower Neuse Basin Association. If Permittee ceases membership, then all instream monitoring requirements
specified in this permit are immediately reinstated. Additionally, DWR will re-evaluate the need for expanded
instream monitoring should the Permittee withdraw from the coalition.
4. For a given wastewater sample, TN = TKN + (NO3-N + NO2-N), where TN is Total Nitrogen, TKN is Total
Kjeldahl Nitrogen, and (NO3-N + NO2-N) are Nitrate and Nitrite Nitrogen, respectively.
5. Compliance with this limit shall be determined in accordance with Special Condition A. (6.) of this permit,
Annual Limits for Total Nitrogen.
6. The quarterly average for total phosphorus shall be the average of composite samples collected weekly during
the calendar quarter (January -March, April -June, July -September, October -December).
7. In the event the Acrolein measurement exceeds 126 µg/L the monitoring frequency shall increase to monthly
for the duration of the permit.
8. Sample location: Upstream, approximately 100 yard above outfall or other Division approved location. The
sample shall be representative of the hardness in the receiving stream, upstream from the outfall. If the
Permittee is a member of the Monitoring Coalition Program, sampling for instream hardness may be waived as
long as the Monitoring Coalition agrees to sample hardness at the upstream location, at a minimum frequency
of quarterly, and the Permittee has obtained approval from DWR -NPDES Permitting Unit. The Permittee is
responsible for submitting instream hardness test results with its permit renewal application package. If
Coalition membership is cancelled or the Coalition terminates instream hardness sampling at the upstream
location, the Permittee will immediately notify the Division and resume sampling for upstream hardness.
9. Chronic Toxicity (Ceriodaphnia) P/F at 1.9%; January, April, July, and October; see Special Condition A. (8.).
b. There shall be no discharge of floating solids or visible foam in other than trace amounts.

A.(5.) CALCULATION OF TOTAL NITROGEN LOADS
[G.S.143-215.1(b)]
a. The Permittee shall calculate the monthly and annual Total Nitrogen (TN) loads as follows:
i. Monthly TN Load (lb/mo) = TN x TMF x 8.34
where: TN = the average total nitrogen concentration (mg/ L) of the
composite samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the
month (MG/ mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual Mass Loading (lb/yr) = Sum of the 12 Monthly TN Loads for the calendar year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and lb/mo) in the discharge
monitoring report for that month and shall report each year's annual results (lb/yr) in the
December report for that year.
A.(6.) ANNUAL LIMITS FOR TOTAL NITROGEN
[G.S.143-215.1(b)]
a. Total Nitrogen (TN) allocations and TN Load limits for NPDES dischargers in the Neuse River
basin apply on a calendar year basis.
b. For any given calendar year, the Permittee shall be in compliance with the annual TN Load limit
in this Permit if:
i. the Permittee's annual TN discharge is less than or equal to its TN Load limit, or
ii. the Permittee is a co-permittee member of a compliance association.
C. If the Permittee is not a co-permittee member of a compliance association and the Permittee's
cumulative annual TN discharge exceeds the effective TN Load limit in this permit at any point
during the calendar year, the Permittee is in violation of its TN Load limit, and each day of a
continuing violation shall constitute a separate violation.
d. The TN Load limit in this Permit (if any) may be modified as the result of allowable changes in
the Permittee's TN allocation.
i. Allowable changes include those resulting from purchase of TN allocation from the
Wetlands Restoration Fund; purchase, sale, trade, or lease of allocation between the
Permittee and other dischargers; regionalization; and other transactions approved by the
Division.
ii. The Permittee may request a modification of the TN Load limit in this Permit to reflect
allowable changes in its TN allocation. Upon receipt of timely and proper application, the
Division will modify the permit as appropriate and in accordance with state and federal
program requirements.
iii. Changes in TN limits become effective on January 1 of the year following permit
modification. The Division must receive application no later than August 31 for changes

days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved
designate signature. Total residual chlorine of the effluent toxicity sample must be measured and
reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity 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.

Effective December 21, 2016, 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 DENR / 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.

A.(19.) STORWATER MONITORING SCHEDULE
The permittee shall complete the analytical samplings in accordance with the schedule specified in the
table below, 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 1 and 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 SPPP and recorded on the DMR. The permittee must report the results from each
sample taken within the monitoring period. 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. The permittee shall maintain semi-annual monitoring until directed otherwise through subsequent renewed
permit or required by SPPP.
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 six-month sampling period.
Failure to monitor semi-annually per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period. "No discharge" from an outfall during a
monitoring period does not constitute failure to monitor, as long as it is properly recorded and
reported.
The permittee shall compare monitoring results to the benchmark values in the Monitoring Requirements
for Outfalls 004, 005, and 006 above. Exceedances of benchmark values require the permittee to increase
monitoring, increase management actions, increase record keeping, and/or install stormwater Best
Management Practices (BMPs) in a tiered program. See Special Condition A.(22.) for descriptions of Tier
One, Tier Two, and Tier Three response actions. In the event that the Division releases the permittee from
continued monthly monitoring and reporting under Tier Two or Tier Three, the Divisions release letter
may remain in effect through subsequent reissuance of this permit, unless the release letter provides for
other conditions or duration.
Benchmark values are not permit limits but should be used as guidelines for implementation of the
permittee's Stormwater Pollution Prevention Plan (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.

NC0003760
A.(20.) QUALITATIVE STORMWATER MONITORING
Qualitative monitoring, a visual inspection of Outfalls 004, 005, 006 stormwater events, shall be
performed as specified during any monitoring stormwater event at stormwater discharge outfall
(SDO). Qualitative monitoring is for the purpose of evaluating the effectiveness of the Stormwater
Pollution Prevention Plan (SPPP) and assessing new sources of stormwater pollution.
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
special condition A. (19.), and 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 SPPP 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 SPPP.

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 Best Management Practices (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 (SPPP).
Page 23 of 30

NC0003760
(Continued A.(20.) QUALITATIVE STORMWATER MONITORING)
Qualitative monitoring is for the purposes of evaluating SPPP 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, the
Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency for some or
all parameters (analytical or qualitative)
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.
A.(21.) STORMWATER POLLUTION PREVENTION PLAN (SPPP)
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as the
Plan. This Plan shall be considered public information in accordance with Part II, Standard Conditions,
Section E, Paragraph 10 of this individual permit. The Plan shall include, at a minimum, the following
items:
1. Site Overview. The Site Overview shall provide a description of the physical facility and the
potential pollutant sources that may be expected to contribute to contamination of stormwater
discharges. The Site Overview shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent map),
showing the facility's location in relation to transportation routes and surface waters; the name
of the receiving waters to which the stormwater outfalls discharge, or if the discharge is to a
municipal separate storm sewer system, the name of the municipality and the ultimate
receiving waters; and accurate latitude and longitude of the points of stormwater discharge
associated with industrial activity. The general location map (or alternatively the site map)
shall identify whether any receiving waters are impaired (on the states 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.
Page 24 of 30

NC0003760
(Continued A.(21.) STORMWATER POLLUTION PREVENTION PLAN (SPPP))
(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 II, Standard
Conditions, Section B, Paragraph 11.
2. Stormwater Management Strategy. The Stormwater Management Strategy shall contain a
narrative description of the materials management practices employed which control or minimise
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. If the secondary containment
devices are connected to stormwater conveyance systems, the connection shall be controlled by
manually activated valves or other similar devices (which shall be secured closed with a locking
mechanism). Any stormwater that accumulates in the containment area shall be at a minimum
visually observed for color, foam, outfall staining, visible sheens and dry weather flow, prior to
release of the accumulated stormwater. Accumulated stormwater shall be released if found to
be uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time of the
release shall be kept for a period of five (5) years. 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.
(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 25 of 30

NC0003760
(Continued A.(21.) STORMWATER POLLUTION PREVENTION PLAN (SPPP))
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 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.
5. 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 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 26 of 30

NC0003760
(Continued A.(21.) STORMWATER POLLUTION PREVENTION PLAN (SPPP))
(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 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 Divisions Annual Summary Data Monitoring Report (DMR) form, available
from the Stormwater Permitting Program s website (See `Monitoring Forms' here:
http/Zportal.ncdenr.org/web/lrinpdes-stormwater].
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 II, Standard Conditions, Section B,
Paragraph 11) 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 consistent with the provisions of this permit, in order to control
contaminants 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.

NC0003760
A. (22.) BENCHMARK COMPLIANCE AND TIERS
The permittee shall report the analytical results from the first sample with valid results within the
monitoring period. The permittee shall compare monitoring results to the benchmark values. Unless
stated otherwise the benchmark values are not permit limits but should be used as guidelines for the
permittee's Stormwater Pollution Prevention Plan (SPPP). When a benchmark value is exceeded, it
requires the permittee to increase monitoring, increase management actions, increase record keeping,
and/or install stormwater Best Management Practices (BMPs) in the tiered program.
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.
5. Record each instance of a Tier One response in the SPPP. Include the date and value of the
benchmark exceedence, 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.
Tier Two
If: 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 and reporting for all Parameters (except mercury).
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 Division of Water Resources (DWR) Regional Office
Supervisor as provided below in Tier Three. The DWR Regional Supervisor 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 res onse obligations throughout the permit renewal process.
Page 28 of 30

NC0003760
(Continued A.(22.) BENCHMARK COMPLIANCE AND TIERS)
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 Division of Water Resources (DWR) Regional Office
Supervisor 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 controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion;
• require the permittee to continue Tier Three obligations through the permit renewal process.
If a Total Maximum Daily Load (TMDL) for mercury is approved for this segment of the Neuse River,
the permittee may be required to monitor mercury more frequently.
The Division will evaluate the monitoring results to determine whether additional Best Management
Practices (BMPs) are needed to control the pollutant(s) of concern to the maximum extent practicable.
If the Division determines additional BMPs are needed, the permittee will be notified and 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.

Footnotes:
1. 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
2. Semi-annual means two times a year. See Special Condition A.(19.) Monitoring Schedule.
3. 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.
4. Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) that discharges
stormwater runoff from area(s) where vehicle maintenance activities occur.
5. The Total Rainfall shall be recorded for the reported measureable stormwater event and include the total
precipitation accumulated for the duration of the rain event. Either an on -site rain gauge or local rain gauge
shall be used to provide the required reading.
A.(24.) REQUIREMENT TO APPLY FOR SEPARATE STORMWATER PERMIT
The permittee is not authorized to discharge stormwater after the expiration date. In order to receive
automatic authorization to discharge beyond the expiration date, the 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

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
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 Averaee
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 Dav
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
The period from Sunday through the following Saturday.
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
(3) 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
preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system, or
Version 1110912011.1

NPDES Permit Standard Conditions
Page 2 of 18
(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
samples at intervals of no greater than 20 minutes apart during any 24-hour period.
➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent
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.)
Daily Maximum
The highest "daily discharge" during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWR or "the Division"
The Division of Water Resources, Department of Environment and Natural Resources.
Effluent
Wastewater discharged following all treatment processes from a water pollution control facility or other point source
whether treated or untreated.
EMC
The North Carolina Environmental Management Commission
EPA
The United States Environmental Protection Agency
Facility Closure
Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this
permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
Version 1110912011.1

NPDES Permit Standard Conditions

Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the CWA.
Instantaneous flow measurement
The flow measured during the minimum time required for the flow measuring device or method to produce a result in
that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab
samples required for the same sampling period so that together the samples and flow are representative of the discharge
during that sampling period.
Monthly Average (concentration limit)
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal
coliform or other bacterial parameters or indicators, the geometric mean of such discharges.
Permit Issuing Authority

307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and 0) 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 defmition 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 Pennittee 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.
Section B. Publicly Owned Treatment Works (POTWs)
Version 1110912011.1

NPDES Permit Standard Conditions
Page 15 of 18
All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:

and
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.
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.
Section C. Munici al Control of Pollutants from Industrial Users.
Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users
discharging to the POTW may be present in the Permittee's discharge. At such time as sufficient information
becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent
limitations for any or all of such other pollutants in accordance with best practicable technology or water quality
standards.
Prohibited Discharges
a. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibition against the
introduction of pollutants or discharges into the waste treatment system or waste collection system which
