Chemical hygiene within the facility was increased. Specifically, spills were clean
immediately. Drip pans are used to collect any potential leaks when transferring materials.
Bulk sacks are bagged before removal from manufacturing buildings.
Outside of the manufacturing buildings rock water breaks were placed in the ditches to slow
overland flow of stormwater to reduce erosion potential. Also, peat moss was placed in the last
rock water break before entering the main drainage ditch to prevent non-rainwater materials
from going into the main drainage ditch.
The beaver activity in the drainage ditches around outfalls 4 and 5 were eliminated to prevent
degradation of culverts and allow flow to continue.
Some soil was removed from behind the research ponds and new grass was seeded with grass
and fertilized.

The truck loading dock was moved from outside to under a covered building.

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 the facility's location in relation to transportation routes and surface
waters;the name of the receiving waters to which the stormwater outfalls
discharge, or if the discharge is to a municipal separate storm sewer system,the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the points of stormwater discharge associated with industrial
activity. The general location map (or alternatively the site map) shall identify
whether any receiving waters are impaired (on the state's 303(d) list of impaired
waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are.
(b) A narrative description of storage practices,loading and unloading activities,
outdoor process areas,dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants that
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary;
the stormwater discharge outfalls; all on-site and adjacent surface waters and
wetlands; industrial activity areas (including storage of materials, disposal areas,
process areas, Ioading and unloading areas, and haul roads); site topography and
finished grade; all drainage features and structures; drainage area boundaries and
total contributing area for each outfall; direction of flow in each drainage area;
industrial activities occurring in each drainage area; buildings; stormwater Best
Management Practices (BMPs); and impervious surfaces. The site map must
indicate the percentage of each drainage area that is impervious, and the site map
must include a graphic scale indication and north arrow.
(d) A list of significant spills or leaks of pollutants during the previous three (3) years
and any corrective actions taken to mitigate spill impacts.
Page 3 of 28

Permit No.NCS000594
(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 amtount 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. The Division may allow exceptions to secondary
containment requirements for mobile refuelers,as with the exemption provided by
amendments to federal SPCC regulations,as long as appropriate spill containment
and/or diversionary structures or equipment is used to prevent discharge to surface
waters. Exceptions do not apply to refuelers or other mobile tankage used primarily
as bulk liquid material storage in a fixed location in place of stationary containers.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs
Page 4 of 28

Permit No.NCS000594
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.
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 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.
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 Part II B and C of this
permit.
6. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill
response and cleanup, preventative maintenance activities,and for any of the facility's
operations that have the potential to contaminate stormwater runoff. The facility
Page 5 of 28

Permit No.NCS000594
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 (element of the Site
uverview),-,
(b) a written re-ceri cation that the stormwater outfalls have been evaluated for
the presence of non st rmwater discharges (element of the Site Overview);
(c) a documented re-evaluad: n of the effectiveness of the on-site stormwater
BMPs (BMP of the Stormwater Management Strategy).
(d) a rc;,;ew an a" cQmn ins-on of s�ie analyacui uu benchmark values(if
applicable) over the past year, including a discussion ab k;'iered Response

The Director giay nofify the permittee when the SWrrP does not meet one or more of
the n-+inimum 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 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 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

Permit No.NCS000594
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 stormwater Best Management
Practices (BMPs) in a tiered program. See below the descriptions of Tier One,Tier Two,and
Tier Three response actions below. In the event that the Division releases the permittee from
continued monthly monitoring and reporting under 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.
The benchmark values in Table 1 are not permit limits but should be used as guidelines for
implementation 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 (no-polar oil and grease and
new motor 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 per month is used when averaged over the calendar year.

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.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall(SDO)unless
representative outfall status(ROS)has been granted. A copy of the Division's letter granting ROS shall
be kept on site. Samples shall also be collected at an in-ditch monitoring point downstream of the
discharge from the facility's riser structure below the pond system.
4 For each sampled measureable storm event,the total precipitation must be recorded. An on-site rain
gauge is required. Where isolated sites are unmanned for extended periods of time,a local rain gauge
reading may be substituted for an on-site reading.
5 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 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 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 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
Page 8 of 28

Permit No.NCS000594
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.
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.
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 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.
6. Note: Benchmark exceedances for a different parameter separately trigger a tiered response.
Page 9 of 28

Permit No.NCS000594
Tier Two
If:The first valid sampling results from two consecutive monitoring periods(omitting periods with no
discharge)are above the benchmark values,or outside of the benchmark range,for any specific parameter at
a specific discharge outfall;
Then:The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples. Monthly(analytical and qualitative) monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period,the permittee is required to submit a monthly
monitoring report indicating"No Flora'to comply with reporting requirements.
4. Alternatively,in lieu of steps 2 and 3,the permittee may,after two consecutive exceedances,exercise the
option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional
Engineer may direct the response actions on the part of the permittee as provided in Tier Three,
including reduced or additional sampling parameters or frequency.
5. Maintain a record of the Tier Two response in the SWPPP.
6. Continue Tier Two response obligations throughout the permit renewal process.
- - -- - ----- - -- -- Tier Three
If:The valid sampling results required for the permit monitoring periods exceed the benchmark value,or
are outside the benchmark range,for any specific parameter at any specific outfall on four occasions,the
permittee shall notify the DEMLR Regional Engineer in writing within 30 days of receipt of the fourth
analytical results;
Then:The Division may but is not limited to:
• require that the permittee revise,increase,or decrease the monitoring and reporting frequency for
some or all of the parameters herein;
• require sampling of additional or substitute parameters;
• require the permittee to install structural stormwater 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;
• require the permittee implement site modifications to qualify for a No Exposure Exclusion;
• require the permittee to continue Tier Three obligations through the permit renewal process.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the 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).
Page 10 of 28

Permit No.NCS000594
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 will be maintained with the SWPPP.

2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(00)regardless of representative outfall status.
A minimum of 60 days must separate monitoring dates, unless additional sampling has
been instituted as part of other analytical monitoring requirements in this permit.
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are
ineffective, or that significant stormwater contamination is present,the permittee shall
investigate potential causes, evaluate the feasibility of corrective actions, and implement
those corrective actions within 60 days, per the Qualitative Monitoring Response, below.
A written record of the permittee's investigation, evaluation,and response actions shall be
kept in the SWPPP.
Page 11 of 28

Permit No.NCS000594
uali#ative 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, 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.
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

When 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
less than 10 percent of the households have broadband access,then a temporary waiver
from the NPDES electronic reporting requirements may be granted and discharge
monitoring data may be submitted on paper DMR forms or alternative forms approved
by the Director. Duplicate signed copies shall be submitted to the mailing address
above. See"How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method,the first DMR is due no later than 30 days from
the date the facility receives the sampling results from the laboratory.
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.

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 Notice of Intent (NOI) form to the Division
of Energy, Mineral and Land Resources (Division)
• Receive approval by the Division,
• Maintain no exposure conditions unless authorized to discharge under a valid
NPDES stormwater permit,and
• Recertify the No Exposure Exclusion 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.

Permit No.NCS000594
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 the facility's location in relation to transportation routes and surface
waters; the name of the receiving waters to which the stormwater outfalls
discharge, or if the discharge is to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the points of stormwater discharge associated with industrial
activity. The general location map (or alternatively the site map) shall identify
whether any receiving waters are impaired (on the state's 303(d) list of impaired
waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas,dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants that
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary;
the stormwater discharge outfalls; all on-site and adjacent surface waters and
wetlands; industrial activity areas (including storage of materials, disposal areas,
process areas,loading and unloading areas,and haul roads); site topography and
finished grade; all drainage features and structures; drainage area boundaries and
total contributing area for each outfall; direction of flow in each drainage area;
industrial activities occurring in each drainage area; buildings; stormwater Best
Management Practices (BMPs); and impervious surfaces. The site map must
indicate the percentage of each drainage area that is impervious,and the site map
must include a graphic scale indication and north arrow.
(d) A list of significant spills or leaks of pollutants during the previous three (3)years
and any corrective actions taken to mitigate spill impacts.
Page 3 of 28

Permit No.NCS000594
(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. 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. The Division may allow exceptions to secondary
containment requirements for mobile refuelers,as with the exemption provided by
amendments to federal SPCC regulations,as long as appropriate spill containment
and/or diversionary structures or equipment is used to prevent discharge to surface
waters. Exceptions do not apply to refuelers or other mobile tankage used primarily
as bulk liquid material storage in a fixed location in place of stationary containers.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs
Page 4 of 28

Permit No.NCS000594
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.
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 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 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
Page 5 of 28

Permit No.NCS000594
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 (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 Division's Annual Summary Data
Monitoring Report (DMR) form,available from the Stormwater Permitting
Program's website (See: https://deq.nc.gov/about/divisions/energy-mineral-land-
res ources/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 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 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.

Permit No.NCS000594
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 e r
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 stormwater Best Management
Practices (BMPs) in a tiered program. See below the descriptions of Tier One,Tier Two,and
Tier Three response actions below. In the event that the Division releases the permittee from
continued monthly monitoring and reporting under Tier Two or Tier Three,the Division's
release Ietter may remain in effect through subsequent reissuance of this permit, unless the
release letter provides for other conditions or duration.
The benchmark values in Table 1 are not permit limits but should be used as guidelines for
implementation of the permittee's 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 (no-polar oil and grease and
new motor 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 per month is used when averaged over the calendar year.

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.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall(SDO)unless
representative outfall status(ROS)has been granted. A copy of the Division's letter granting ROS shall
be kept on site. Samples shall also be collected at an in-ditch monitoring point downstream of the
discharge from the facility's riser structure below the pond system.
4 For each sampled measureable storm event,the total precipitation must be recorded. An on-site rain
gauge is required. Where isolated sites are unmanned for extended periods of time,a local rain gauge
reading may be substituted for an on-site reading.
5 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 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 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 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
Page 8 of 28

Permit No.NCS000594
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.
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.
Tier One
If:The first valid sampling results are above a benchmark value,or outside of the benchmark range,for any
parameter at any outfall;
Then:The permittee shall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving sampling
results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential,and select the specific feasible:source controls,operational controls,or physical
improvements to reduce concentrations of the parameters of concern,and/or to bring concentrations
within the benchmark range.
4. Implement the selected feasible actions within two months of the inspection.
S. Record each instance of a Tier One response in the 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.
b. Note: Benchmark exceedances for a different parameter separately trigger a tiered response.
Page 9 of 28

Permit No.NCS000594
Tier Two
If:The first valid sampling results from two consecutive monitoring periods (omitting periods with no
discharge)are above the benchmark values, or outside of the benchmark range,for any specific parameter at
a specific discharge outfall;
Then:The permittee shall:
I. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples. Monthly(analytical and qualitative)monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period,the permittee is required to submit a monthly
monitoring report indicating"No Flow"to comply with reporting requirements.
4. Alternatively,in lieu of steps 2 and 3,the permittee may,after two consecutive exceedances,exercise the
option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional
Engineer may direct the response actions on the part of the permittee as provided in Tier Three,
including reduced or additional sampling parameters or frequency.
S. Maintain a record of the Tier Two response in the SWPPP.
b. Continue Tier Two response obligations throughout the permit renewal process.
- _ Tier Three
If The valid sampling results required for the permit monitoring periods exceed the benchmark value,or
are outside the benchmark range,for any specific parameter at any specific outfall on four occasions,the
permittee shall notify the DEMLR Regional Engineer in writing within 30 days of receipt of the fourth
analytical results; - - --- -
Then:The Division may but is not limited to:
• require that the permittee revise,increase,or decrease the monitoring and reporting frequency for
some or all of the parameters herein;
• require sampling of additional or substitute parameters;
• require the permittee to install structural stormwater 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;
• require the permittee implement site modifications to qualify for a No Exposure Exclusion;
• require the permittee to continue Tier Three obligations through the permit renewal process.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the 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).
Page 10 of 28

Permit No.NCS000594
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 will be maintained with the SWPPP.

Footnotes:
1 Monitoring Frequency: Twice per year during a measureable 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 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 SWPPP.

Permit No.NCS000594
ual#ative Monitoring ReVonse
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, 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.
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. (2.) Submitting Reports
1. Reporting Requirements
[Supplements Section E. (1.) and Supersedes Section E. (2.11
When the Division's electronic reporting system is able to accept NPDES stormwater
permit monitoring data,the permittee shall report discharge monitoring data
electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR)
internet application. The Division will notify permittees when eDMR is ready to accept
stormwater monitoring data.
Until the Division's eDMR application is compliant with EPA's Cross-Media Electronic
Reporting Regulation (CROMERR),permittees will be required to submit discharge
monitoring data to the state electronically using eDMR and also will be required to
complete the eDMR submission by printing,signing, and submitting one signed original
and a copy of the computer printed eDMR to the following address:

When 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
less than 10 percent of the households have broadband access,then a temporary waiver
from the NPDES electronic reporting requirements may be granted and discharge
monitoring data may be submitted on paper DMR forms or alternative forms approved
by the Director. Duplicate signed copies shall be submitted to the mailing address
above. See"How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method,the first DMR is due no later than 30 days from
the date the facility receives the sampling results from the laboratory.
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.
