The site is located at 333 Southridge Parkway in Bessemer City, North Carolina and manufactures
plastic piping for various applications. The general location of the site is depicted on Figure 1 and
includes the receiving waterbody of the facility stormwater discharge. Additionally, a detailed site
map is included as Figure 2 and Figure 3A. As shown on the figures, a primary manufacturing
building is located on the north side of the facility which includes the pipe manufacturing
processes. Processes include surge tank loading, Gaylord box storage, pellet blending, extrusion
and pipe fabrication, trimming, and pipe grinding. Other processes on-site include unloading rail
and truck shipments of pellets, fueling, material storage (pellet and regrind), mobile grinding, and
associated mobile grinder and other vehicle maintenance.
The entire site is on approximately 44.8 acres, and industrial areas occupy approximately 36 of
those 44.8 acres. Impervious area associated with industrial activity is approximately 30 acres.
2.2 Pollution Prevention Team (PPT)
To easily manage and assign tasks for the implementation of the SWPPP, a pollution prevention

2.3 Industrial Drainage Area Map
The majority of the industrial areas on-site is considered impervious surface (paved or compacted
dirt and gravel). Exceptions include the vegetated area in the center of the site, the vegetated
swale north of the rail line, and the areas surrounding the sediment forebay and retention pond.
Specific areas of the property, including the employee parking lot east of the manufacturing
building and the southeastern entrance to the site, are not included in the industrial area as no
industrial material is stored or exposed to stormwater in those areas.
The site is located within two industrial drainage areas as described below:
• Drainage Area 1: This section includes the industrial area to the southeast of the rail line.
Stormwater flows southeast to either the various catch basins on the site or directly overland
to the retention pond at the southeast corner of the facility. The retention pond discharges the
stormwater to Oates Creek and ultimately to Crowders Creek.
• Drainage Area 2: This section includes the area to the northwest of the rail line. In this area,
stormwater accumulates into a vegetated swale and discharges along Southridge Parkway.
This water will eventually discharge to the Bessemer City Municipal Separate Storm Sewer
System (MS4) which enters Oates Creek and ultimately discharge to Crowders Creek.
6/20

Ramboll-Stormwater Pollution Prevention Plan
2.4 Receiving Waterbody
The site discharges from two locations to Oates Creek. The stormwater that enters Oates Creek
discharges to Crowders Creek which is the first waterbody listed on the North Carolina Integrated
Waters Map. Crowders Creek (ID NC11-135C) is a 303(d) listed impaired stream segment that
covers from S Linwood Road, Gastonia, NC to its junction of Abernethy Creek in Bessemer City. It
is impaired for aquatic life, but as of March 2023,there is no TMDL set for the waterbody.
2.5 Significant Spills
No significant spills have been reported for this site. Any reportable spill of industrial material that
occurs at this site will be recorded and reported in the Log of Significant Spills attached as
Appendix C. Reporting procedures and responsibilities are discussed further in Section 4.4 and
Section 4.5.
3. Potential Pollutants in Stormwater
3.1 Potential Pollutant Narrative and Assessment
The General Permit requires SWPPPs to outline and describe different practices used on site and
their potential pollutants involved. Pollutant sources are shown on Figure 2. The General Permit
specifically outlines five pollutant source categories:
• Unloading and loading process areas;
• Storage practices;
• Outdoor process areas;
• Dust or particulate generation and control; and
• Waste disposal practices.
Under these categorizations, the following pollutant sources are identified and located at the ADS
site in Bessemer City.
• Shipping and receiving bay
• Rail car unloading area
• Fixed rail car storage
• Finished product storage areas
• Forklift activity and manufacturing
• Regrind silo storage
• Fueling storage area
• Vehicle maintenance area
• Mobile grinder maintenance area
• Mobile grinding regrind storage
• Recovered pellet storage
• Cardboard compactor dumpster
3.1.1 Shipping and Receiving Bay
Gaylord boxes containing polypropylene and polyethylene pellets are unloaded off of trucks in the
shipping and receiving bay. This bay is located on the western corner of the manufacturing
building. These boxes are unloaded using forklifts and moved to an inside Gaylord box storage
area. Industrial material from the shipping and receiving that could enter the stormwater
conveyance system include raw polypropylene pellets and polyethylene pellets.
3.1.2 Rail Car Unloading Area
Another method of delivering pellets to the site is through the onsite rail line. Rail cars are
brought onto the site and attached to vacuum lines along the track to convey pellets into the
pellet storage areas inside the manufacturing building. Should these storage areas reach capacity,
7/20

Ramboll-StarmwaWr Pollutlon Pr entlon Plan
pellets can be redirected to the fixed rail cars on-site that act as storage containers until more
storage is available. Connections to the rail and vacuum line are made with camlock connections
and secured. Industrial material from the rail car unloading area that could enter the stormwater
conveyance system include raw polypropylene and polyethylene pellets.
3.1.3 Fixed Rail car Storage
If the interior surge tanks are full when unloading pellets from the rail line, the surplus pellets can
be unloaded into two fixed rail cars located adjacent to the tracks. These rail cars are affixed with
four air cyclone filters each. Industrial material from the fixed railcar storage includes
polypropylene and polyethylene pellets.
3.1.4 Finished Product Storage Areas
Finished pipe product is stored outside until they are ready to be shipped and delivered to the
applicable client. These areas, located on the eastern and western side site, contain plastic piping
stored in piles exposed to the environment. These finished pipes are mostly inert. Industrial
material from the finished product storage yards that could enter the stormwater conveyance
system include plastic pipe trimming leftover inside the pipe and mobilized sediment from vehicle
movement.
3.1.5 Forklift Activity and Manufacturing
While the bulk of the manufacturing processes is protected from stormwater inside of the
manufacturing building, spilled material can track outside to be mobilized. During warm periods of
the year, bay doors to the outside are opened, and overhead fans are turned on for heat
dissipation. Industrial materials, such as plastic particulates, may be deposited outside these
doors. Forklift traffic exiting the building to conduct work outside may track materials outside. The
industrial material from forklift activity includes polypropylene pellets and regrind and
polyethylene pellets and regrind.
3.1.6 Regrind Silo Storage
Plastic pipe particulate is generated from the fixed indoor grinder unit. The fixed grinder unit
discharges particulate material into four regrind storage silos. The material is stored in the silos
until they can be loaded and transported off-site to another ADS site. The silos are vented
through filter socks that catch and collect airborne particulate material. The silos are unloaded via
connections at the bottom of the silo. Industrial material from the regrind silo storage that could
enter the stormwater conveyance system include polypropylene and polyethylene regrind from
the connection points as well as the filter socks.
3.1.7 Fueling Storage Area
A fueling shed is adjacent to the stormwater conveyance channel with a covered fueling tank
within a secondary containment wall.The tank serves the onsite vehicles and forklifts used in
daily material handling operations. Industrial material from the fueling storage area that could
enter the stormwater conveyance system include diesel fuel, motor oils, and other vehicle Fluids.
3.1.8 Vehicle Maintenance.Area
Directly east of the site's entrance security checkpoint;vehicles are maintained and repaired when
needed.This activity is operated open to the environment. Industrial materials from the vehicle
maintenance area include motor oils, maintenance Fluids, and any other vehicle Fluids.
3.1.9 Mobile Grinder Maintenance Area
A maintenance area for the mobile grinder is located at the edge of the western storage bay. The
maintenance is conducted outside under no cover. Industrial materials associated with the mobile
-- —— -- - — eizo-- - -

Ramboll-Stormwater Pollution Prevention Plan
grinder regrind storage include polypropylene and polyethylene regrind, motor oil, and other
vehicle fluids.
3.1.10 Mobile Grinder Regrind Storage
During operation of the mobile grinder, defect or out of specification pipe segments are ground up
into regrind material.This occurs directly southwest of the manufacturing building.The grinder
deposits the regrind material into open top Gaylord storage boxes for ultimate off-site disposal.
This operation is conducted outside under no cover. Industrial materials associated with the
mobile grinder regrind storage include polypropylene and polyethylene regrind.
3.1.11 Recovered Pellet Storage
Pellets that are spilled in various process areas described above are swept and recovered into
containers for ultimate off-site disposal. This process happens throughout the site, including the
rail car unloading area. Industrial material associated with the recovered pellet storage containers
include polyethylene and polypropylene pellets and plastic regrind.
3.1.12 Cardboard Compactor Dumpster
Near the entrance to the site,cardboard boxes, including Gaylord boxes, are compacted. This
container is outside and open to the environment. Industrial material associated with the
cardboard compactor include polyethylene and polypropylene pellets and plastic regrind
depending on the contents of the boxes compacted.
3.2 Non-Stormwater Discharges
The site does have non-stormwater discharges. The site pressure washes lifts to remove dust and
mud. These washings are done without cleaning agents, so this non-stormwater discharge is
allowable under the North Carolina General Permit.
4. Stormwater Management Strategy
4.1 Feasibility Study
The ADS site in Bessemer City keeps its manufacturing processes under cover of the primary
manufacturing building. Vehicle fueling is performed utilizing secondary containment. A significant
portion of the facility containing industrial activities is exposed to stormwater due to the nature of
the business activities of the facility. The practicality of eliminating or reducing stormwater
exposure for the remaining industrial processes, including silo storage, rail unloading, finished
product storage, and vehicle maintenance is deemed as practically and economically unfeasible.
The facility implements BMPs and housekeeping controls, including pellet management procedures
and a stormwater retention pond with a forebay, which are used to minimize industrial materials
from stormwater discharge to receiving waterbodies.
4.2 Secondary Containment Requirements
Two identified oil containers are located on-site and used for refueling purposes. These tanks are
located in the center of the site in the fueling storage area outlined on Figure 2.The tank contents
are listed in Table 2 below, as well as and secondary containment measures in place.

Tank 1 is under cover, and the containment contains no manual release valve. Any material that
does collect in this secondary containment wall will not be exposed to stormwater and will likely
be a product of a spill. Tanks 2 and 3 are located within a 20-inch secondary containment wall.
These tanks contain waste mixtures of oil and a glycol mixed waste mixture. Spill contents will be
removed and disposed of properly as soon as practical and safe to do so. Documenting the
management of spill contents within secondary containment will include observations, description
of contents within the containment, and the date and time of the release/clean up. Documentation
will be retained with the SWPPP for a period no less than 5 years. A copy of the observation report
is contained in Appendix D.
4.3 Summary of Best Management Practices
4.3.1 Structural BMPs
The structural BMPs are utilized on-site are listed below:
• Catch basins
• Air cyclone filters
• Silo air filters
• Sedimentation forebay
• Retention pond
Air Cyclone Filters:
To limit the amount of particulate available in storage, the cyclones are equipped on rail storage
cars to keep pellets collected from the rail unloading area and prevent them from being deposited
on the ground around the storage containers.
Silo Air Filters:
Silo air filters are utilized on the regrind silos to filter particulate from the silo exhaust and
minimize stormwater contact.
Catch Basins:
Catch basins are implemented around certain process and storage areas to better capture pellet
and regrind waste before they enter the retention pond and discharge to the environment. These
are located in areas directly nearby or downstream of particulate generating processes and
contain catch basin inserts, which help remove particulate from stormwater.
Sedimentation Forebav:
Prior to ultimate discharge for Drainage Area 1 to a retention pond, this forebay helps treat and
retain the sediment and industrial material in the stormwater.
Retention pond:
The last structural BMP implemented to treat runoff is the approximately 25,000 square foot
retention pond. This pond holds stormwater prior to discharge to not only hold sediment runoff
but to also allow the facility to visually identify any excess spilled material in the pond and clean
up spills identified prior to discharge to the receiving waterbody.

Ramboll-Stormwater Pollution Prevention Plan
4.3.2 Non-structural BMPs
Non-structural BMPs are utilized to limit stormwater pollution discharging from the site to the
receiving waterbody. The pollutant sources outlined in Section 3 are identified as being at a higher
risk for spill potential so controlling that risk is essential to minimizing the site's effect on
stormwater quality. The following non-structural BMPs are implemented at the site to reduce
industrial pollutants in stormwater discharges:
Pollutant Source Measures Implemented and Rationale
• Unload trucks on impervious concrete surfaces to
facilitate timely cleanup of pellet spills.
Use proper forklift handling techniques to transfer
Gaylord boxes inside the manufacturing building;
Shipping and receiving bay • Utilize sweeping, spill kits, and periodic inspections
for pellet/grinding management.
• Use and maintain spill kits including shovels,
brooms, 5-gallon buckets, pans, and portable
vacuums to timely address pellet spills.
• Unload rail cars on impervious concrete surfaces to
facilitate timely cleanup of pellet spills.
Utilize rail car unloading shrouds to direct pellet
flows into the vacuum line and reduce pellet spill
frequency and volume.
Use portable pans and buckets that are placed
underneath connection points to the rail and fixed
vacuum line to collect pellets that fall during
uncoupling.
Utilize a half pipe trough underneath connection
points to the rail cars to act as a secondary
Rail car unloading area collection point to facilitate clean up efficiency.
• Routinely inspect and sweep the rail unloading area
as needed to address spills in a timely manner.
Collect pellet spills and dispense them into
designated containers along the rail line to facilitate
disposal of pellets to plastic recyclers.
• Use and Maintain spill kits including shovels,
brooms, 5-gallon buckets, pans, and portable
vacuums to timely address pellet spills.
Utilize geotextile catch basin insert filters to catch
pellets and sediment that may be mobilized into the
stormwater conveyance channel.
• Keep rail cars on impervious concrete surfaces to
facilitate timely cleanup of pellet spills.
• Routinely inspect and sweep fixed rail car storage
area as needed to address spills in a timely manner.

Ramboll-Stomwater Pollution Prevenhon Plan
Pollutant Source Measures Implemented and Rationale
• Utilize geotextile catch basin insert filters to catch
pellets and sediment that may be mobilized into the
stormwater conveyance channel.
• Use air cyclone filters on top of the fixed rail cars to
prevent spills of pellets when unloading from rail
line.
• Sweep the paved storage yards on an as needed
Finished product storage yards basis to keep the area clean of industrial material.
Utilize geotextile catch basin insert filters to catch
pellets and sediment that may be mobilized into the
stormwater conveyance channel.
Routinely inspect and sweep process areas and
Forklift Activity and manufacturing entrance and exits to the manufacturing building
area as needed to address spills in a timely manner
and prevent tracking of industrial material.
Employ air filter socks on the silos for catching
Regrind silo storage regrind materials lost during venting.
• Keep silos on impervious surfaces to facilitate timely
cleanup of pellet spills.
Keep the fueling tank underneath the fueling shed
canopy to prevent direct rainwater flow.
Fueling Storage Area • Contain the fueling tank and nozzle in a secondary
containment wall to collect any spills or leaks and
prevent them from comingling with stormwater
runoff.
Routinely inspect and sweep the areas and clean up
spills as they occur;
Vehicle maintenance area • Use oil absorbents and drip pans to capture fluids
lost during vehicle maintenance; and
Dispose of used oil/fluids into proper waste oil
receptacles located on-site.
Mobile grinder maintenance area ' Keep the maintenance activity under a liner to
facilitate the cleanup of regrind s ills.
• Sweep the paved storage yards on an as needed
basis to keep the area clean of industrial material.
Mobile grinding regrind storage • Utilize geotextile catch basin insert filters to catch
pellets and sediment that may be mobilized into the
stormwater conveyance channel.
Dispose of full containers in an appropriate time
Recovered pellet storage frame to avoid spills of recovered pellets during
storage and waste hauling.
4.4 Spill Response and Responsible Procedures
Spill response begins as soon as the spill has been discovered and safe enough to implement spill
response equipment. Spill response kits on-site include equipment, such as 5-gallon buckets,
pans, brooms, shovels, and portable backpack vacuums that can help quickly clean up small pellet
spills.
Investigation of reported leaks and spills will be handled by managers and other designated
responsible staff outlined in this SWPPP. These designated persons will assist in containing and
wzo

Ramboll-Stormwater Pollution Prevention Plan
Spill Response and Responsible Procedures and will assist in containing and cleaning up spills
using the specified emergencies protocols for oil and/or hazardous waste spills set by the Site and
by the federal, state, and local governments.
While plastic pellets and regrind are not regulated under oil and hazardous material regulations,
the spill response procedures will be nearly the same. Additionally other materials such as
solvents need to be handled and disposed of properly. For specific solvent management practices,
reference the solvent management plan in Appendix E. For spills on the Site, utilize the following
procedures to assess and respond to a spill event:
• Guarantee proper training has been given to staff responding to the spill.
• Notify nearby workers and supervisors of the spill.
• Evacuate the area around the spill to the extent appropriate for the nature of the spill; if fires
or an explosion develops, evacuate to a distance of a half-mile.
• If trained and authorized by an appropriate authority, contain the spill area to the best extent
possible without jeopardizing personal safety.
• If necessary (based on size, context, and nature of spill and the Site's emergency procedures),
notify first responders.
• If safe to do so, determine source, material type, and quantity of the spilled material.
• For spills in secondary containment walls, appropriate removal of the spilled must be
completed as soon as practical:
o The clean-up process includes removal of residual contamination that may be left behind
after the spill. If in the diesel tank shroud, the secondary containment volume must be
flushed with clean water three times with each volume of water being properly disposed of
before the area is deemed clean.
o A sample of the initial stormwater out of the containment wall must be tested following the
spill to confirm cleanliness of the unit. Parameters tested includes pH, spilled material, and
any other pollutant the owner knows, or suspects may be present. If the water contains no
pollutants, then the secondary containment can return to normal operation; else, the water
must be disposed of properly and the cleaning process must be repeated.
• For spills on-site:
o Gather trained spill response teams to clean up the spill.
o Utilize brooms and pans to contain the spilled material to prevent mobilization in the
stormwater conveyance system.
o Containerize all recovered pellets, regrind, contaminated absorbents and other clean up
materials in properly labeled drums or containers.
• For releases that could potentially impact soil or water through conveyance structures,
reaching outside of the facility boundary, or exceeding reportable quantity limits, notify the
Plant Manager. Refer to 40 CFR 110.6, 117, 302.4 and 355 Appendix A for a list of different
material types with their reportable quantities.
• The Plant Manager will determine applicable reporting requirements.
4.5 Spill Response Reporting Procedure
Once initial spill containment has been completed or an evacuation has been conducted, the Plant
Manager will contact the necessary authorities. If an oil spill or hazardous material spill above
reportable thresholds occurs,the North Carolina Division of Energy, Mineral, and Land Resources
(DEMLR) Regional Office and National Response Center must be contacted as well as the LEPC for
the area. Other reportable spills include:

4.6 Employee Training
Training facility personnel is essential to prevent and control potential stormwater pollution
activities. Employees applicable to training requirements have responsibilities for spill response
and clean up, conduct preventative maintenance activities, and/or conduct any activities that
have potential to contaminate stormwater runoff. The training practices used by ADS for these
specified employees are as follows:
• Train all applicable employees to report any issues regarding stormwater Issues or spills/leaks
to their supervisor.
• Identify and document that require additional training based on their role and responsibilities.
• Ensure all pollution prevention team members are trained for their function (including BMP
implementation, and evaluating effectiveness of said BMPs, visual observations and monitoring
activities).
• Maintain stormwater training materials and manuals.
• Specify a training schedule(annual).
• Perform annual training for the SWPPP and record training attendance and documentation.
• Employee training is given to all applicable employees upon hiring and annually thereafter.
This training includes but is not limited to:
o Objectives of the SWPPP
o General stormwater awareness
o Stormwater pollution control laws and regulations
o BMP implementation
o BMP effectiveness evaluation
o Visual observations
o Monitoring activities
o Safe methods for handling and storing chemicals and hazardous materials
o Where to find and how to use spill control equipment
o Spill and emergency response procedures including proper accumulation and disposal of
associated wastes
o Instructions to new employees in respect to BMPs
o Assessment of activities at the site that may affect the SWPPP.
All training is recorded in an employee training log and kept along with this SWPPP. A copy of the
employee training log is included in Appendix F. This copy must include a signed signature of each
employee trained on the assigned day
5. Housekeeping Schedule, Facility Inspections, and Monitoring
Requirements
Section 5 describes the visual and analytical stormwater monitoring and inspection requirements
outlined in the General Permit. Requirements will be revised as necessary and in accordance with
Section 6.1 of this SWPPP.
5.1 Preventative Maintenance and Good Housekeeping Program
Preventative maintenance and good housekeeping will be conducted on a defined schedule.
Identification of areas that need maintenance will be conducted through scheduled routine
inspections of the following:
• Stormwater discharge outfalls
• Areas where industrial activity is conducted (outlined in Section 3.1)
• Drainage features and structures (outlined in Figure 2 and 2A)
• Structural BMPs onsite (outlined in Section 4.3.1)
15/20

Ramboll-Stortowawr Pollution Prevention Plan
The inspections will be conducted on a semi-annual basis to identify areas of deficiency, areas
where spills have occurred or might occur. Any needed maintenance to remediate these issues
should be scheduled. These inspections will be conducted by qualified personnel with at least one
member of the PPT participating. All maintenance activities should be documented and retained
with the SWPPP.
In addition to evaluating compliance with the BMPs established for the site, the inspection team
will also attempt to identify potential problems before they develop into stormwater exposures or
other environmental hazards. It is the employee's responsibility to correct these problems
wherever possible and communicate the extent of these problems to the Plant Manager, EHS
team members, or other members of the Pollution Prevention Team. In general, the inspections
should identify:
• Leaks and other integrity concerns with storage containers (e.g., wind damage, signs of
corrosion, support or foundation failure, deterioration of piping/pumps/pressure valves, etc.;
• Improper material handling practices;
• Accumulated liquids in containment areas;
• Improper labeling and storage practices;
• Poor housekeeping;
• Accumulated particulate matter on the ground surface; and
• Open or deteriorated containers.
The first half of the year is defined by the General Permit as January to June with the second half
being July to December. There must be at least 60 days separating the inspection dates except in
the case that inspections are performed more frequently. This inspection is different from the
inspections required later on in Section 5.3. A copy of the routine facility inspection is included in
Appendix G.
5.2 Quantitative Analytical Monitoring
Analytical testing is conducted on facilities that perform any on-site vehicle maintenance activities
exposed to stormwater in quantities more than 55-gallons of new motor oil or hydraulic oil per
month. This estimate is averaged over a single calendar year. This facility uses approximately
2750 gallons of oil in a year, so the sampling requirement is applicable to the site. Outfalls 001
and 002 will be monitored. Parameters that need to be monitored are summarized and presented
in Table 3 below:
Table 3: Applicable Analytical Monitoring Parameter Benchmarks
Discharge Parameter Benchmark Units Sample Frequency* Sample Type
Non-Polar Oil and Grease 15 m /L uarterl Grab
Chemical Oxygen Demand 120 Mg/L Quarterly Grab
COD
Total Suspended Solids 100 nn /L Quarterly Grab
H 6-9 SU Quarterly Grab
Total Rainfall - inches Quarterly Rain oauge
New Motor/Hydraulic _ gal/month monthly Estimate
Oil Usage
*Frequency changes if corrective action tier is increased
Monitoring will be conducted on a quarterly basis or one sample per defined monitoring periods.
The monitoring periods are defined below:
• Period 1: January 1 - March 31
• Period 2: April 1 - June 30
16/20

Ramboll-Stormwater Pollution Prevention Plan
Period 3: July 1 — September 30.
• Period 4: October 1 — December 31
The sample dates between periods must be separated by a minimum of 60 days. When collecting
these samples, personnel conducting sampling will note the date, time and exact place of the
sample, and individuals conducting sampling.
All stormwater samples must be collected at outfall locations outlined in Figure 2. Sampling must
take place during a measurable storm event where a discharge occurs from vehicle maintenance
areas onsite. A measurable storm event is defined by the permit as a storm event that results in
an actual discharge from the permitted outfall for the site.The storm must be at least 72 hours
after the last measurable storm event and sampling of the storm is not required outside of
standard facility operating hours. The storm must be recorded on an on-site rain gauge or a
regional gauge within one mile of the site.
The monitoring schedule may change pending if benchmark exceedances occur and the facility
enters either a Tier Two or a Tier Three status. More details on monitoring periods during
benchmark exceedance status are discussed in Section 5.4.
Failure to monitor semi-annually in accordance with the General Permit may result in the Division
requiring the permittee to monitor monthly for a specified period. Exceptions to this are situations
of extreme weather conditions during a monitoring period or a monitoring period with "no
discharge"from the outfall. In these scenarios, the lack of monitoring results does not constitute
failure to monitor if the reasons are documented and reported properly.
5.3 Qualitative Analytical Monitoring
In addition to quantitative monitoring, permittees must also conduct qualitative analytical
monitoring. This type of monitoring will be conducted during measurable storm events.
Qualitative monitoring requires visual inspections of all outfalls that receive stormwater from
industrial areas identified on Figure 2. Comparative to quantitative monitoring, an Inability to
perform qualitative monitoring due to adverse weather conditions requires proper documentation
in the SWPPP and in the monitoring forms to not constitute a failure to monitor. Additionally, a
minimum of 60 days must be between separate monitoring date unless specified in other
analytical monitoring requirements in the General Permit.
The runoff characteristics that must be evaluated on a semi-annual basis in qualitative monitoring
are summarized below:
• Clarity
• Color
• Erosion or deposition at the outfall
• Floating Solids
• Foam
• Odor
• Oil Sheen
• Other obvious indicators of stormwater pollution
• Suspended Solids
If the results from qualitative monitoring indicate that implemented BMPs are ineffective in
minimizing stormwater contamination or the stormwater contamination is significant, the
permittee must investigate the causes of the pollution and potential corrective actions. Within 60
days of identifying the stormwater issue, the permittee will be responsible for implemented those

corrective actions and keep a written record of evaluations of potential causes, evaluations of
corrective actions, and actions taken in response to the observations.The documentation will be
recorded in the SWPPP. Visual observation forms used by the site are included in Appendix H.
5.4 Non-Stormwater Discharge Evaluation
A certification form on annual non-stormwater discharges evaluations is included in Appendix I.
These evaluations will be conducted annual to recertify the presence or absence of non-
stormwater discharges. Changes of any kind to the presence of non-stormwater discharges will be
documented and kept with the SWPPP.
5.5 Benchmark Exceedance Tiers
The State of North Carolina has established benchmark exceedance tiers to be set in response to
facilities exceeding a parameters benchmark identified in Table 3.These tiers are Tier One,Tier
Two, and Tier 3:
5.5.1 Tier One Status
Upon the first valid sampling result exceeding or being out of range on a parameter's set
benchmark, the facility will enter Tier One status. In Tier One status, the fallowing actions must
be conducted by the permittee:
• Throughout the Tier One status,
o document the exceedance(s) and each required response action in the SWPPP. Include the
following:
• The date and value of the benchmark exceedance;
• Inspection date
• The personnel conducting the inspection
• The selected actions
• And the date the actions were implemented
• Within two weeks of Tier One status:
o Conduct a stormwater management inspection of the facility, identify and evaluate
possible causes of exceedance, and notify the DEMLR's Regional Office of the exceedance
date and value via email or in writing;
• Within one month of Tier One status:
o Select specific feasible courses of action to reduce concentration of parameters of
concern;
• Within two months of Tier One status:
0 implement selected feasible actions.
Note: Benchmark exceedances for different parameters trigger separate tiered Responses.
5.5.2 Tier Two Status
Upon receiving the first valid sampling results from two consecutive monitoring periods (omitting
no discharge periods) in which results exceed or are outside of the parameter's allowable
benchmark range, the facility will enter Tier Two and conduct the following actions:
• Throughout Tier Two status:
o document exceedances and actions taken in the SWPPP;
• Within two weeks of Tier Two status:
o Notify the DEMLR's regional office about the exceedance via email or in writing
o Conduct a stormwater management inspection; and
o Identify and evaluate possible causes of the benchmark exceedance
• Within one month of Tier Two status:
o Select feasible courses of action to reduce pollutant concentration causing the exceedance.
• Within two months of Tier Two status:
18/20

Ramboll-Stomwater Pollution Pmentlon Plan
o Implement selected feasible actions
o Implement monthly monitoring at outfalls where sampling results exceed the benchmarks
for all parameters until three consecutive results are recorded below benchmarks.
5.5.3 Tier Three Status
If the permittee receives valid sampling results that exceed benchmark values or are outside of
benchmark ranges for a parameter on four occasions, the permittee will notify the DEMLR
Regional Engineer in writing within 30 days of receiving the fourth results. The division may
require the permittee to conduct the following actions:
• Throughout Tier Three status:
o Create and document exceedances in the Action Plan and
o Conduct monthly monitoring for all parameters at the outfall until three consecutive
samples are below their respective benchmarks;
• Within the first two weeks of Tier Three status:
o Notify the DEMLR regional Office of the exceedance date and value via email or in writing
o Conduct a stormwater management inspection
o Identify and evaluate possible causes for the exceedance
• Within one month of Tier Three status:
o Prepare an Action Plan that should include specific, feasible courses of action to reduce
pollutant concentration causing the exceedance. Submit to DEMLR's regional office for
review; and
o Upon approval from the DEMLR, implement the Action Plan and notify the DEMLR upon its
completion.
5.6 Electronic Monitoring Reporting
Under federal regulations, submittals of discharge monitoring reports (DMRs) and program
reports are required.The Division requires that these reports be submitted under the North
Carolina Division of Water Resources Electronic Discharge Monitoring Report internet application
(eDMR). Registration for the eDMR program must be completed 30 days after certificate of
coverage is granted. In these reports, monitoring results will be summarized from the previous
months. DMRs will include the date, time and exact place the sample measurement(s) was taken,
individual performing sampling, date of sample analysts, individual performing sample analysis,
analytical techniques and methods used, and the results of the analysis.The first DMR must be
submitted within 30 days of receiving the sampling results from the laboratory.The DMR form
applicable to this site is included in Appendix J. If submittal to the electronic DMR system is
infeasible, a waiver can be granted by submitting an electronic reporting waiver to the Division.
This must be done at least 60 days prior to the facility's reporting deadline. This waiver cannot
exceed 5 years of coverage to which thereupon it will expire. At such expiration, monitoring data
and reports will be submitted to the Division electronically unless the permittee reapplies for the
waiver.
All eDMR submissions will be signed by the responsible person overseeing the site manufacturing
processes certifying the document under penalty of law. These records, including all DMRs and
eDMRs, will be retained for at least 5 years from the date of the report. This record retention
policy may be extended by the director at any time. They must be made available upon request
by the Offices of the Division for public inspection.

6. Updating and Implementing the SWPPP
6.1 Annual SWPPP Update and Update Requirements
The SWPPP plan shall be amended upon any changes in design, construction, operation, site
drainage, maintenance, or configuration of physical features of the site that will have a legitimate
effect on the quality of stormwater discharges to receiving surface waterbodies. In the event of an
update, each section of this SWPPP will be reevaluated and corrected to reflect the reality of the
site's operation. The Director is authorized to notify the permittee if the SWPPP does not meet
each requirement set by the General Permit. In this situation the permittee will have 30 days
after the notice to submit a SWPPP modification time schedule to meet the requirements of the
General Permit. Once completed, a written certification will be sent to the Director (conforming to
Part III, Standard Conditions,Section B, Paragraph 5 of the General Permit). An annual update
will include the permittee completing the following:
• Document and review the Site's implemented best management practices.
• Inspect each outfall for the presence of non-stormwater discharges and create a written
recertification
• Update the list of significant spills or leaks of pollutants with records gathered over the past
three years.
• Compare the analytical data from sampling over the past year to the assigned benchmark
values for the relevant industry category.
o Include a discussion of the Site's current Tiered Response status
o In this comparison, utilize the Stormwater Permitting Unit's Data Monitoring Report (DMR)
form available on the Units Website.
6.2 Implementation of the SWPPP
The implementation of the SWPPP and associated BMPs will be used to prevent the entry of
contaminants into stormwater runoff that comingles with nearby receiving waterbodies. Executing
the SWPPP will require the Permittee to document monitoring results, inspections, maintenance
activities, and employee training. Included in this documentation will be a document containing
sampling data and of actions taken to implement best management practices associated with
industrial activity. This document will include activities pertaining to vehicle maintenance. Records
of activities stated above will be kept for a minimum of five years and be made readily available
to the Director or another representative of the Director upon request.
