1.0 INTRODUCTION
This Stormwater Pollution Prevention Plan (SWPPP) has been developed by Hanley
Environmental, PLLC on behalf of Cargo Transporters, Inc. for the facility located 3382 North
Oxford Street, Claremont, Catawba County, North Carolina (the site). This facility is
authorized to discharge stormwater to receiving waters under National Pollutant Discharge
Elimination System (NPDES) General Permit No. NCG080000 Certificate of Coverage No.
NCG080426. This SWPPP has been developed to satisfy Part B of the NPDES General Permit.
The General Permit is included as Appendix A and a checklist of minimum requirements for
the SWPPP under Part B of the NPDES General Permit is included as Appendix B.
This plan was initially developed using information provided by Cargo Transporters, Inc.,
observations made during site reconnaissance performed on October 6, 2022, and
information from previous facility SWPPPs prepared by Froehling & Robertson, Inc. (April 13,
1999) and Blue Ridge Environmental Services, Inc. (January 9, 2012).
The SWPPP provides a comprehensive site -specific plan that details measures and practices
to reduce stormwater pollution and is based on an evaluation of the pollution potential of
the site. The SWPPP will be updated whenever there is a change in the design, construction,
operation, or maintenance of the facility that significantly affects the potential for
stormwater pollution.

2.4.1 Aboveground Storage Tank Fuel Tank Farm
Fueling activities are primarily conducted near the aboveground storage tank (AST) Fuel Tank
Farm located in the south-central portion of the site. The AST Fuel Tank Farm consists of two
15,000-gallon diesel ASTs, one 10,000-gallon diesel AST, one 10,000-gallon new oil AST, and
one 6,000-gallon used oil AST. The ASTs are located within a secondary concrete containment
structure that has a single manual drain valve that is kept in the locked position. The drain
valve is located within the concrete sump in the secondary containment structure and is
plumbed through subgrade piping to a drop box which drains to Outfall 2. In the event of a
release, a submersible pump in the concrete sump transfers the liquid to a 6,500-gallon
holding tank where it will be properly characterized and disposed of. A diesel dispenser is
located within a paved containment with perimeter berms located east of the Fuel Tank
Farm. The fueling area has a collection drain which is plumbed through the subgrade to the
sump located within the secondary containment structure. In addition, a spill kit is present
at the dispenser to contain accidental discharges. The fueling area is covered with an awning.
Diesel and new and used oil are pumped through subgrade lines from the Fuel Tank Farm
to the maintenance shop. A former 1,500-gallon kerosene AST is located near the Fuel Tank
Farm but is currently out -of -service. Additionally, approximately eight totes of diesel exhaust
fluid are stored within the secondary containment structure. Although unlikely, controlled
releases from the AST Fuel Tank Farm would flow laterally to the east and south and
discharge at Outfall 2.
The AST Fuel Tank Farm loading area is located west of the AST Fuel Tank Farm,
topographically upgradient of the ASTs. The loading area has a fill box with ports that connect
to aboveground piping that are used to fill the ASTs. The loading area consists of a concrete
pad with paved berm whose outfall is a concrete drain channel that slopes east into the AST
secondary containment structure. Additionally, the aboveground piping is located above the
concrete drain channel which provides secondary containment. Therefore, discharges that
occur during loading/unloading activities would typically be captured by the AST Fuel Tank
Farm secondary containment.

Cargo Transporters, Inc.
2.4.2 Gasoline Fueling Area
1I1kHanley
11 Environmental
Engineering & Consulting
A gasoline fueling area is located near the forklift storage building on the western portion of
the site, north of the maintenance shop. The gasoline fueling area has a 500-gallon double -
walled gasoline AST situated on asphalt and a fuel dispenser mounted on a concrete pad
surrounded by asphalt pavement. Bollards surround the tank and dispenser to prevent
impact damage from vehicles. The gasoline tank is loaded on an as -needed basis through a
hose from the delivery truck which parks adjacent to the AST. Discharges near the gasoline
fueling area would flow southwest toward a stormwater drain that leads to Outfall 1.
2.4.3 Truck Washing and Body Shop
Truck washing and body shop activities are within the building in the southwestern portion
of the site. Several 55-gallon drums and 275-gallon totes of cleaning/washing detergents are
located within and around the exterior of the two truck wash bays. Drums and totes are
delivered to the site by box truck or tractor trailers. The materials are unloaded and moved
by forklift or drum dolly to various locations around the wash bays and body shop. Wash
water from the trucks is contained by the sloped pavements and curbing of the wash bay
and is gravity fed via floor drains to an oil -water separator (OWS) that consists of four
compartments. Water from the first compartment of the OWS is recycled to the wash bay to
reduce potable water use. The OWS discharges to an approximately 6,500-gallon poly tank
located along the southern boundary. The poly tank has a high-level pump that discharges
to the municipal wastewater system. Body shop activities consist of minor cosmetic repair
and painting. Products stored in the body shop include various paints, solvents, glues,
cleaners, etc. in containers typically 5-gallon or less. Truck washing and body shop activities
are completed indoors. In general, outdoor process areas are limited to material storage
along the exterior of the building. A spill from around the truck wash bays/body shop would
flow south towards Outfall 3.
2.4.4 Truck Maintenance
Truck maintenance activities are conducted in the maintenance shop located on the western
portion of the site. An approximately 270-gallon motor oil AST is located in the maintenance
1.1

Stormwater Pollution Prevention Plan IIkHanley
Cargo Transporters, Inc. IF Environmental
Engineering & Consulting
shop. The AST has secondary containment and is located along the east wall. The oil AST is
filled with new motor oil from the larger oil AST in the Fuel Tank Farm and used as needed
in the maintenance shop. Two diesel fuel dispensers are located in the building. Fuel nozzles
are stored with drip pans beneath the holders. Several 55-gallon drums of non -oil products
including antifreeze, diesel exhaust fluid, windshield wiper fluid, and other products are
present in the maintenance shop. Drums are delivered to the site by box truck or tractor
trailers. The materials are unloaded and moved by forklift or drum dolly to various locations
around the maintenance shop. Floor drains located in the maintenance shop drain to an
approximately 500-gallon below grade OWS located south of the body shop. The 500-gallon
OWS discharges to the truck washing/body shop OWS. Maintenance activities are completed
indoors. In general, outdoor process areas are limited to material storage along the exterior
of the building.
2.4.5 Emergency Generators
An emergency generator equipped with an approximately 125-gallon diesel belly tank serves
the operations building located north of the AST Fuel Tank Farm. The diesel tank is
constructed of steel and double walled. The diesel generator is loaded on an as -needed basis
through a hose from the delivery truck parked adjacent to the generator. Uncontrolled
releases from the diesel generator tank would flow laterally to the south toward a
stormwater drain that discharges to Outfall 2. A natural-gas powered generator supplies the
administrative building.
2.4.6 Outdoors Storage Areas
The Cargo Transporters facility utilizes a covered outdoor storage area attached to the east
side of the maintenance shop which is primarily for used tire storage. Other areas of the site
utilized for outdoor storage includes east of the forklift storage building which is used for
scrap parts and south of the AST loading area which is used for miscellaneous parts and
equipment storage.
7

Stormwater Pollution Prevention Plan IIkHanley
Cargo Transporters, Inc. IF Environmental
Engineering & Consulting
2.4.7 Electrical Transformers
The Cargo Transporters facility includes a pad -mounted transformer with an oil capacity
greater than 55 gallons located in the eastern portion of the site that is related to the
municipal lift station. Maintenance and cleanup of releases from the transformer are
generally the responsibility of Duke Energy. The oil -containing electrical transformer is
discussed in this plan because it is located on the facility property. A spill from the
transformer would likely pool radially from the transformer pad and infiltrate into soil.
Several pole -mounted transformers with oil capacities less than 55 gallons are also located
at the site. The transformers are owned and maintained by Duke Energy.
2.4.8 Dust or Particulate Generating and Control Processes
Dust or particulate generating processes include light cosmetic and painting activities inside
the body shop. Dust or particulate generating activities are conducted indoors to limit the
potential for stormwater impacts. Majority of the parking and roadways on site are paved to
minimize dust generation. The southeastern portion of the tractor parking area is covered
with gravel and is properly maintained through regular grading to keep the lot smooth and
level to minimize dust generation.
2.4.9 Waste Disposal
General solid waste is stored outdoors in commercial dumpsters located on paved surfaces.
A waste dumpster is located near the body shop and a scrap metal dumpster is staged near
the maintenance building. The dumpsters are not covered from precipitation. The waste
dumpsters are serviced by contracted vendors on an as -needed basis.
2.5 General Location Map
The Cargo Transporters facility is comprised of three parcels of land (Catawba County Parcel
IDs 376209065876, 376205171665, and 375212966535) totaling approximately 54.29 acres
at 3350, 3382, and 3390 North Oxford Street, Claremont, Catawba County, North Carolina
(site). A topographic site location map is included as Figure 1. Parcel ID 375212966535 is
improved with an approximately 6,300 square foot (sq ft) administrative building and parking
area. Parcel ID 376209065876 consists of an approximately 19,900 sq ft operations building,
LZ

Stormwater Pollution Prevention Plan IIkHanley
Cargo Transporters, Inc. IF Environmental

an approximately 12,500 sq ft maintenance shop, an approximately 9,400 sq ft body shop
and truck wash building, storage structures, and fueling areas. Parcel ID 376205171665
includes paved employee and tractor trailer parking lots and a stormwater detention pond.
Mull Creek boarders the site to the east. A site map of the facility features is included in
Figure 2. The surrounding area generally consists of single-family residential land.
The site drainage generally slopes to the south and east towards outfalls that discharge to
Mull Creek (Figure 3). The southwestern portion of the site slopes towards North Oxford
Street. The receptor of stormwater runoff from the site is Mull Creek which borders the site
to the east. Mill Creek flows into Lyle Creek located approximately 4,800 feet to the
northeast. The North Carolina Division of Water Resources (NCDWR) classified Mull Creek as
a Water Supply IV (WS-IV). NCDWR defines WS-IV as waters used as sources of water supply
for drinking, culinary, or food processing purposes where a WS-I, II or III classification is not
feasible. These waters are also protected for Class C uses such as aquatic life propagation,
survival and maintenance of biological integrity, wildlife, secondary contact recreation, and
agriculture. WS-IV waters are generally in moderately to highly developed watersheds or
Protected Areas. Mull Creek is not identified as an impaired receiving water per NCDEQ and
does not have an established Total Maximum Daily Load (TMDL).
2.6 Site Map
The site map for this facility is included as Figures 2 and 3. The site maps show the location
of the site buildings, site topography, approximate stormwater flow directions, material
storage areas, drainage structures, outfall drainage areas, parking lots, and other impervious
areas. Generally, runoff at the site drains to the south and east and is controlled by surface
topography and stormwater features such as concrete, vegetative, and riprap swales,
underground piping, intake and discharge culverts, the stormwater detention pond, and
other features. Drainage features ultimately discharge to five stormwater outfalls, identified
as Outfall 1 through Outfall 5. A portion of stormwater runoff is expected to infiltrate
pervious surfaces at the site, or travel as sheet flow from areas outside the developed

This section describes areas at the facility where industrial materials or activities are exposed
to stormwater, or from which authorized non-stormwater discharges originate. For each
outfall area and source of pollutant, pollutants of concerns are identified. This section also
evaluates the feasibility of implementing practices to eliminate or reduce stormwater
pollution.

3.2 Feasibility Study
As required by the NPDES General Permit, the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure of
material processes to precipitation and run-on flows was evaluated.
Facility operations are conducted primarily indoors. Outdoor operations include parking,
material storage, fuel loading/unloading and vehicle refueling. When possible, materials
should be stored indoors or beneath a covering. Based on limited indoor storage capacity,
limited scrap materials and cleaning detergents are stored outdoors. Construction of
additional storage buildings or storage structures are not economically feasible at this time.
The facility may evaluate construction of an awning for the gasoline fueling station and
extending the outdoor covered area near the maintenance shop to reduce the potential for
stormwater pollution associated with activities in these areas.
Reducing runoff rate and flow velocity of stormwater is likely to result in the collection and
carry of fewer pollutants in the flowing water. Runoff rate and flow velocity can be reduced
by reducing runoff volume, increasing pervious surfaces, installing vegetated channels, and
installing check dams and/or riprap, or adding stormwater detention structures. Several of
these methods have been utilized at the site including a stormwater detention pond, check
dams, and riprap. The potential for adding additional detention ponds, reducing impervious
surfaces, or additional riprap is not technically feasible at this time.
To reduce the potential for pollutants to discharge with stormwater from the site,
manufactured treatment devices may be considered. Treatment devices are pre -fabricated
stormwater treatment structures utilizing settling, filtration, absorptive/adsorptive
materials, vortex separation, and/or other appropriate technology to remove pollutants
from stormwater runoff. Based on the BMPs implemented at the facility including the facility
inspection program, preventative maintenance, and spill prevention and response
procedures, the use of manufactured treatment devices is not warranted at this time.

4.0 EVALUATION OF STORMWATER OUTFALLS
Cargo Transporters certifies that the site stormwater discharge outfalls have been evaluated
for the presence of non-stormwater discharges. The Non-Stormwater Discharge Evaluation
and Certification will be recertified on an annual basis (Appendix Q. If non-stormwater
discharges are observed, Cargo Transporters will identify the source and record whether the
discharge is permitted by rule or a different permit. The environmental significance of the
non-stormwater discharge will be evaluated and documented in Appendix C.
13

Stormwater Pollution Prevention Plan IIkHanley
Cargo Transporters, Inc. OF Environmental

5.0 BEST MANAGEMENT PRACTICES
The installation and implementation of best management practices (BMPs) is 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.
As required by the NPDES General Permit, this BMP summary shall be reviewed and updated
annually.
5.1 Stormwater BMP Summary
The development of stormwater BMPs involves four steps:
• Formation of a team of qualified facility personnel who will be responsible for preparing
and updating the BMP document and assisting the facility manager in its implementation;
• Assessment of potential storm water pollution sources;
• Selection and implementation of appropriate management practices and controls; and,
Periodic evaluation of the ability of the plan to prevent storm water pollution and to
comply with the terms and conditions of the BMP document.
Stormwater BMPs are used to treat or limit pollutants and other negative effects of
stormwater runoff in order to meet permit requirements. Two major categories of BMPs
include structural and non-structural. Structural BMPs refer to physical structures designed
to eliminate pollutants from stormwater runoff, reduce downstream erosion, provide floor
control, and promote groundwater recharge. Structural BMPs at the site include a
stormwater detention pond and riprap swales and buffers. Non-structural BMPs focus on
management of pollutants at the source by minimizing exposure to runoff. When properly
developed and implemented, non-structural BMPs can be effective in minimizing potential
stormwater pollution and can reduce the need for structural BMPs.
Non-structural BMPs were developed for areas and operations that have the highest
potential for stormwater pollution including vehicle and equipment cleaning areas, vehicle
and equipment maintenance areas, vehicle refueling, loading and unloading operations, and
14

outdoor storage areas. Off -site remote fueling and locomotive sanding are mentioned under
BMPs as required by the General Permit, however, off -site remote fueling and locomotive
sanding are not applicable to this facility.
5.1.1 Vehicle and Equipment Cleaning Areas
BMPs to prevent or minimize contamination of the stormwater runoff from areas used for
vehicle and equipment cleaning were developed and implemented at the facility. Vehicle and
equipment washing occurs in two covered wash bays located in the south-central portion of
the site. The wash bays have trench/floor drains that collect wash water and discharge to an
oil/water separator located south of the wash bay stations. The oil/water separator is
comprised of four compartments; water from the first compartment is recycled through the
wash water to limit the potable water intake. The oil/water separator discharges to an
approximately 6,500-gallon poly tank located along the southern site boundary. The poly
tank discharges to the municipal wastewater system after a certain volume of liquid
accumulates. In addition to the BMPs described above, the following BMPs are also in place
at the site:
• Wash vehicles and equipment only in the designed wash bay areas.
• Properly handle and store cleaning drums and totes.
• Perform routine inspections of tanks, drums, totes, and equipment to identify leaks,
deterioration, and/or damage.
• Monitor the oil/water separator effluent and compartment tanks for signs of
breakthrough or abnormal operation.
• Train employees in proper vehicle and equipment washing and water management
practices.
• Detergents used outdoors shall be biodegradable and the pH adjusted to be in the
range of 6 to 9 Standard Units (SU).
The point source discharge of vehicle and equipment wash waters, including tank cleaning
operations, are not authorized underthe NPDES permit and must be discharged to a sanitary
sewer in accordance with applicable industrial wastewater pretreatment operations.

5.1.2 Vehicle and Equipment Maintenance Areas
Vehicle and equipment maintenance is performed primarily in the maintenance shop, with
light cosmetic work conducted at the body shop. A covered outdoor storage area is attached
to the east side of the maintenance shop which is primarily for used tire storage. Floor drains
located in the maintenance shop drain to an approximately 500-gallon below grade OWS
located south of the body shop. The 500-gallon OWS discharges to the truck washing/body
shop OWS. Maintenance activities are completed indoors. The following BMPs have been
implemented for vehicle maintenance.
• Never discharge cleaning solutions used for engines or parts into the storm drain or
parking lot. Do not wash or rinse parts outdoors.
• Maintenance activities are conducted by trained personnel.
• Monitor the oil/water separator effluent for signs of breakthrough or abnormal
operation.
• Routinely inspect vehicles and equipment, including tanks/pipes/hoses, for signs of
leaks, deterioration, or damage.
• Store oil and other chemical products properly with secure lids. Store products
indoors when possible.
• Spill kit materials are routine inspected and restocked as needed.
5.1.3 Vehicle Refueling
BMPs prevent fuel and oil from entering the storm drain system as a result of fueling vehicles
at the site. Fueling activities are conducted at the gasoline fueling station near the Fork Lift
Maintenance Shed, at the AST Fuel Tank Farm in the central portion of the site, and within
the maintenance shop. Refueling at the AST Fuel Tank Farm has secondary containment
provided by a drain system that collects spilt fuel and transports the fuel to the AST Fuel Tank
Farm secondary containment concrete sump. BMPs for refueling include the following:
• Inspect the fueling area prior to refueling for signs or leaks or discharges.
• Inspect the dispensing system for signs of leaks or damage.
16

Stormwater Pollution Prevention Plan IikHanley
Cargo Transporters, Inc. IF Environmental
Engineering & Consulting
• Fueling areas are equipped with spill kit materials. Spill kit materials are routine
inspected and restocked as needed.
• Fueling activities are conducted by authorized, trained personnel. Personnel must
remain with the vehicle while refueling activities occur. Contractors responsible for
refueling trucks must follow all BMPs and safety procedures.
5.1.4 Loading and Unloading Operations
The ASTs are typically filled on a daily basis by an off -site vendor. Product is delivered from
a delivery truck to the tanks via hose connection. The AST Fuel Tank Farm loading area is
located west of the AST Fuel Tank Farm, topographically upgradient of the ASTs. The loading
area has a fill box with ports that connect to aboveground piping that are used to fill the
ASTs. The loading area consists of a concrete pad with paved berm whose outfall is a
concrete drain channel that slopes east into the AST secondary containment structure.
Therefore, discharges that occur during loading/unloading activities would typically be
captured by the AST Fuel Tank Farm secondary containment. The gasoline tank is loaded on
an as -needed basis through a hose from the delivery truck to the AST. Discharges near the
gasoline fueling area would flow southwest toward a stormwater drain that leads to Outfall
3.
Drums and totes are delivered to the site by tractor trailer or box trucks and unloaded by
forklifts. The drums/totes are then moved manually or by forklift for storage prior to use.
Chock blocks are placed under at least two wheels to secure the delivery vehicle in place
during unloading of materials. Readily available spill kit materials are located in the general
vicinity of unloading activities.
Cargo Transporters personnel are made aware of all oil unloading and delivery activities. A
copy of the loading/unloading procedures should be posted at all locations where vehicle
loading/unloading occurs. Truck loading and unloading activities meet the minimum
requirements and regulations established by the North Carolina Department of
Transportation.

SA.S Outdoor Storage Areas
111►Hanley
11 Environmental
Engineering & Consulting
Outdoor storage areas are located near the forklift storage building and to the south of the
AST fueling area. The following BMPs have been put in place to minimize the potential for
stormwater impacts.
• All materials should be stored indoors whenever possible. If materials must be stored
outdoors, they should be stored beneath a covering.
Remove scrap waste materials promptly.
• Close and seal each container securely. Frequently inspect containers for signs of
leaks, deterioration, or damage.
• Vehicle parts and products stored outdoors should be covered, degreased, and/or
drained of fluids prior to storage.
• Outdoor storage areas are to be swept regularly to remove fines and debris that have
accumulated in the area.
5.1.6 Off -Site Remote Fueling
The Cargo Transporters facility does not conduct remote fueling or maintenance at off -site
locations.
5.1.7 Locomotive Sanding
Locomotive sanding is not applicable to the Cargo Transporters facility.
S.2 Secondary Containment Plan
Secondary containment is required for bulk storage of liquid materials including petroleum
products; storage in any amount of water priority chemicals listed in Section 313 of Title III
of the Superfund Amendments and Reauthorization Act (SARA); and storage of hazardous
substances in any amount. In addition to the SWPPP, Cargo Transporters created a Spill
Prevention, Control, and Countermeasures (SPCC) Plan that is implemented at the facility.

5.2.2 Manually Activated Valves or Other Similar Devices
Cargo Transporters utilize a manually operated valve in the AST secondary containment
structure. The valve shall remain closed while not in use and may be opened to release
stormwater following an inspection of the accumulated fluid. The inspection should be
documented as discussed in Section 5.2.3.
5.2.3 Accumulated Stormwater Release Commitment and Records
Prior to discharge of accumulated stormwater, a sample will be collected in a clear container
for visual observation including color, foam, staining, visible sheens, etc. The information
related to the accumulated stormwater release including name, date/time, description of
stormwater accumulation observations, and quantity will be documented and shall be
maintained for up to five years. If visual observation determines the accumulated
stormwater may be impacted, the source of contamination will be determined and corrected
to prevent future impacts.
Cargo Transporters personnel commit to prevent the release of accumulated contaminated
stormwater.

5.3 Spill Prevention and Response Procedures
The Spill Prevention and Response Procedures (SPRP) identify hazardous material storage
areas, identifies a list of trained facility personnel responsible for implementing the SPRPs
(including signed and dated acknowledgment to accept responsibilities), spill response
materials and locations, written procedures for proper cleanup and disposal of spilled
materials, and a list of significant spills or leaks of pollutants that have occurred during the
previous three years. In addition, Cargo Transporters implemented a SPCC Plan at the facility,
prepared by Hanley Environmental and dated November 2022.
5.3.1 Areas for Potential Spills
An evaluation of the facility was conducted to identify areas where potential spills could
result in stormwater pollution. The following areas and potential pollutants were identified.
AST Fuel Tank Farm - Gasoline, diesel, oil, and diesel exhaust fluid have the potential to enter
stormwater during loading/unloading and refueling activities.
Gasoline Fueling Area - Gasoline from loading/unloading and refueling activities have the
potential to enter stormwater if a spill occurs.
Truck Washing Area - Cleaners and detergents stored around the wash area have the
potential of entering stormwater if not properly stored and handled.
Chemical and Oil Storage in Maintenance Shop - chemicals and oil stored inside the
maintenance shop has the potential to contribute to stormwater pollution if not stored and
handled properly.
Outdoor Storage Areas - Raw materials stored on pavement near the forklift storage building
and AST loading area have the potential to contribute to stormwater pollution.
Waste Disposal - Waste has the potential to come in direct contact with stormwater and
contribute to stormwater pollution if not managed correctly.

When reporting a discharge, provide the following information:
• The name, location, and phone number of Cargo Transporters facility;
• The date and time of discharge;
• The type of material discharged;
• An estimate of the total quantity entering navigable water;
• The source of the discharge;
• A description of all affected media;
• The cause of the discharge;
• Any damages or injuries caused by the discharge;
• Actions to stop, remove, and mitigate the effects of the discharge;
• Whether an evacuation may be needed; and
• The names of individuals and organizations that have been contacted.
5.3.5 List of Significant Spills
The facility has not had a significant spill and/or leak at the site in the past three years. This
list should be updated on an annual basis. Annual updates are documented in Appendix C.
SA Solvent Management Plan
The Solvent Management Plan (SMP) incorporated at the facility is designed to identify
solvents stored and used in facility operations, disposal of solvents, and management
procedures and engineering measures to prevent accidental release to stormwater. Solvent
inventory will be updated on an annual basis, and necessary revisions to the solvent
management plan will be made if required.
Solvents present at the site, and those that were used or stored at the facility within the past
three years, including the following:
• Acetone;
26

Stormwater Pollution Prevention Plan
Cargo Transporters, Inc.
• Urethane Reducer;
• Powercan Blending Solvent;
• Paint thinner; and,
• Parts washer fluid.
1I1kHanley
OF Environmental
Engineering & Consulting
Generally, solvents present at the site are stored in containers under five gallons in a storage
closet in the Body Shop. The facility primarily uses solvents as parts and metals cleaners and
are applied directly to parts and metals as needed. Used solvents for disposal are not
typically generated at the site. Parts washer fluid is collected in appropriate containers and
disposed of off -site by a contractor vendor.
Stormwater exposure potential for solvents at the site are considered low based on the
storage and use of solvents inside the building. A release of solvents inside the facility would
be captured by spill response materials which would prevent the solvents from exiting the
building. Solvent containers should be inspected prior to use and periodically for signs of
leakage or damage.
5.5 Representative Outfall Status
The Cargo Transporters facility is not currently granted representative outfall status.
Representative outfall status may be granted by the NCDEQ Division of Energy, Mineral, and
Land Resources if a facility has multiple discharge locations with substantially identical
Stormwater discharges that require sampling.

6.0 PREVENTATIVE MAINTENANCE AND GOOD
HOUSEKEEPING PROGRAM
A preventative maintenance and good housekeeping program (PMGHP) for the facility is
included in this section. The PMGHP is designed to create and manage a work environment
that prevents stormwater pollution.
6.1 Good Housekeeping
Good housekeeping practices are performed daily at the Cargo Transporters facility to
reduce or eliminate stormwater contamination. The following good housekeeping practices
are utilized:
• Store materials in appropriate, labeled containers. Store materials indoors or under
cover, when possible, to limit contact with stormwater. All outdoor storage containers
shall have lids that adequately close. Safety Data Sheets for products stored on site
are kept up to date.
• Dumpsters and waste containers are inspected periodically and covered when
possible. Trash and debris around containers are collected and disposed of in proper
containers. Waste disposal should be arranged to minimize the accumulation of
waste material. Disposal records are maintained.
• Outdoor areas are swept periodically to remove debris.
• Truck washing activities are only to occur at the truck washing bays where wash water
is collected by the oil/water separator system.
• Ensure spill kit materials are properly stocked and in functional locations.
6.2 Preventative Maintenance
Preventative maintenance involves the regular inspection, testing, and replacement or repair
of equipment, containers, and stormwater systems to eliminate or minimize the potential
for stormwater impacts. A preventative maintenance program can prevent breakdowns and
failures through adjustment, repair, or replacement prior to a major failure occurring.
Preventative maintenance activities performed at the site include:

Stormwater Pollution Prevention Plan I IH �anley
Cargo Transporters, Inc. IOFEnvironmental
Engineering & Consulting
• Visually inspect tanks, drums, containers and surrounding areas for evidence of leaks,
deterioration, or damage;
• Visually inspect stormwater drop inlets, detention pond, swales, and other
stormwater features for evidence of damage and/or debris/sediment;
• Replace tanks, drums, containers, or stormwater features as needed;
• Repair overhead cover if leaks occur; and,
• Provide and maintain secondary containment.
Maintenance records such as material replacement or repair will be kept on file for up to
three years.
6.3 Spill Prevention and Response Procedures
The General Permit requires the development of a spill prevention and response procedures
be established for the facility. Spill prevention and response procedures are described in
Section 5.3.
6.4 Erosion and Sediment Control
Erosion and sediment control is accomplished at the site by the use of crushed aggregate
surfacing of nonpaved parking and traffic areas which are then typically bordered by
vegetated areas. The majority of the developed areas of the site are covered with pavement,
buildings, or grass. Erosion control at the stormwater outfalls is accomplished bythe periodic
replacement of riprap and gabion baskets to reduce/prevent scouring.
63 Employee Training
Employee training will be provided for facility personnel responsible for operations that have
the potential to contaminate stormwater runoff. Training will be conducted during new hire
orientation or shortly after, and then on an annual basis. The training shall be documented
by the date, signature, and printed or typed name of each employee trained. Signatures may
be original or electronic.
The annual employee training shall include, at a minimum, the following topics:

Engineering & Consulting
Monitoring Reports (DMRs), and visual qualitative monitoring reports shall be maintained for
a period of at least 5 years from the date of the sample, measurement, or report.
6.7.1 Qualitative Monitoring of Stormwater Discharges
Qualitative monitoring provides a quick and inexpensive way to evaluate the effectiveness
of the SWPPP, identify potential for new sources of stormwater pollution, and to prompt a
response to pollution.
Visual inspections/observations shall be made at each stormwater outfall that discharges
Stormwater using the Division's Stormwater Discharge Outfall Qualitative Monitoring Report
(QMR) form (Appendix E). Observations shall include:
• Color;
• Odor;
• Clarity;
• Floating solids;
• Suspended solids;
• Foa m;
• Oil sheen;
• Deposition at or immediately below the outfall;
• Erosion at or immediately below the outfall; and,
• Other obvious indicators of Stormwater pollution.
If qualitative monitoring indicates that the SWPPP and/or existing Stormwater BMPs are
ineffective, or that significant stormwater contamination is present, then Cargo Transporters
shall investigate potential causes, evaluate the feasibility of corrective actions, and
implement those feasible corrective actions within 60 days. A written record of the
investigation, evaluation, and response actions shall be kept in Appendix C.
6.7.2 Analytical Monitoring of Stormwater Discharges
Based on the facility using more than 55 gallons of new motor oil per month when averaged
over the calendar year, analytical monitoring shall be performed at Outfalls 1 through 4. As
31

Stormwater Pollution Prevention Plan likHanley
Cargo Transporters, Inc. OF Environmental
Engineering & Consulting
indicated in a Compliance Evaluation Inspection from NCDEQ dated August 29, 2022,
analytical monitoring is not required for Outfall 5.
Outfall analytical monitoring parameters are included in Part E of the General Permit.
Analytical results for each parameter shall be compared to the benchmark values. If an
exceedance of any benchmark value occurs, a tiered response is required for the outfall
where the exceedance was collected, as described in the General Permit.
6.8 Disposal Plan for Spent Lubricants and Fuels
Used solvents for disposal are not typically generated at the site. Parts washer fluid is
collected in appropriate containers and disposed of off -site by a contractor vendor.
Used oil collected in the used oil AST are disposed of by an approved disposal contractor on
an as -needed basis. The used oil is transported off the site for proper disposal/recycling.

Permit No. NCG080000
PART A: NCGO80000 PERMIT COVERAGE
All persons desiring to have facilities covered by this General Permit must register with the Division
of Energy, Mineral, and Land Resources (the Division) by the filing of a Notice of Intent (NOIJ and
applicable fees. The NOI shall be submitted and a Certificate of Coverage (COCA issued prior to any
discharge of stormwater associated with industrial activity to the surface waters of the state or to a
municipal separate storm sewer system (MS4) conveying discharges to surface waters.
Any owner or operator not wishing to be covered or limited by this General Permit may make
application for an individual NPDES permit in accordance with NPDES procedures in 15A NCAC 2H
.0100, stating the reasons supporting the request. Any application for an individual permit shall be
made at least 180 days prior to commencement of discharge.
This General Permit does not cover activities or discharges covered by an individual NPDES permit
until the individual permit has been revoked or rescinded. Any person conducting an activity
covered by an individual permit, but which could be covered by this General Permit, may request
that the individual permit be rescinded and coverage under this General Permit be provided.
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 Exclusion from NPDES stormwater
discharge permit requirements. Any owner or operator wishing to obtain a No Exposure Exclusion
from permitting must submit a No Exposure Certification NOI form to the Division; must receive
approval from the Division; must maintain no exposure conditions unless authorized to discharge
under a valid NPDES stormwater permit; and must recertify the No Exposure Exclusion annually.
Any facility may apply for new or continued coverage under this permit until a Total Maximum
Daily Load (TMDL) for pollutants for stormwater discharges is established. A TMDL is for one or
more watersheds with one or more impaired waters. The TMDL sets one or more pollutant -loading
limits that affects one or more watersheds, or portion of a watershed, draining to one or more
impaired waters. A list of approved TMDLs for the state of North Carolina can be found at
https:lldeg.nc.govlabout/divisions/water-resources/planning/modeling-assessment/tmdls. To
not be subject to the TMDL, each facility with one or more discharges to watersheds affected by a
TMDL must demonstrate it does not have reasonable potential to violate applicable water quality
standards for those pollutants identified in the TMDL as a result of discharges. If the Division
determines that discharges have reasonable potential to cause water quality standard violations,
the facility shall apply for an individual permit 180 days prior to the expiration date of this General
Permit. After that individual permit becomes effective, the facility will no longer have coverage
under this General Permit. Although there is not a TMDL for every impaired water, the permittee
must identify impaired waters in the General Location Map, as outlined in Part B of this permit. The
Department of Environmental Quality - Division of Water Resources integrated reports
(https: I Ideq.nc.govlabout/divisions/water-resources/planning/modeling-assessment/water-
quality-data-assessment/integrated-report-files) include assessments of waters monitored in
North Carolina. Use the most recent final report to identify impaired waters.
Until this permit expires or is modified, rescinded, or revoked, the permittee is authorized to
discharge stormwater to the surface waters of North Carolina or a MS4 which has been treated and
managed in accordance with the terms and conditions of this General Permit and the requirements
of the permittee's COC.
The permittee's COC is hereby incorporated by reference into this General Permit. Any violation of
the COC is a violation of this General Permit and subject to enforcement action as provided in the
General Permit.
Page 1 of 35

Permit No. NCG080000
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 discharges allowed by this General Permit shall not cause or contribute to violations of Water
Quality Standards. Discharges allowed by this permit must meet applicable wetland standards as
outlined in 15A NCAC 213.0230 and .0231 and water quality certification requirements as outlined
in 15A NCAC 2H .0500.
If industrial activities expand or change after issuance of the COC such that the types of discharges
are affected, the permittee must first contact the Division to determine if modifications to the COC
are necessary.
This permit does not relieve the permittee's responsibility for compliance with any other applicable
federal, state or local law, rule, standard, ordinance, order or decree.

Permit is renewed, existing permittees do not need to submit a renewal request or pay a renewal
fee unless directed by the Division. New applicants seeking coverage under a renewed General
Permit must submit a NOI to be covered and obtain a Certificate of Coverage (COC) under the
renewed General Permit [15A NCAC 02H .0127(e)].
I-3. Planned Changes
The permittee shall give notice to the Director as soon as possible of any planned changes at the
permitted facility which could significantly alter the nature or quantity of pollutants discharged [40
CFR 122.41(1)]. This notification requirement includes pollutants which are not specifically listed in
the General Permit or subject to notification requirements under 40 CFR Part 122.42 (a).
I-4. Transfers
This General Permit is not transferable to any person without prior written notice to and approval
from the Director in accordance with 40 CFR 122.61. The Director may condition approval in
accordance with NCGS 143-215.1, in particular NCGS 143-215.1(b) (4)b.2., and may require
modification or revocation and reissuance of the COC, or a minor modification, to identify the new
permittee and incorporate such other requirements as may be necessary under the CWA [40 CFR
122.41(1)(3), 122.61] or state statute. The Permittee is required to notify the Division in writing in
the event the permitted facility is sold or closed.
I-5. When an Individual Permit May be Required
The Director may require any owner/operator authorized to discharge under a COC issued
pursuant to this General Permit to apply for and obtain an individual permit or an alternative
General Permit. Any interested person may petition the Director to take action under this
paragraph. Cases where an individual permit may be required include, but are not limited to, the
following:
(a) The discharger is a significant contributor of pollutants;
(b) Conditions at the permitted site change, altering the constituents and/or characteristics of
the discharge such that the discharge no longer qualifies for a General Permit;
(c) The discharge violates the terms or conditions of this General Permit;
(d) A change has occurred in the availability of demonstrated technology or practices for the
control or abatement of pollutants applicable to the point source;
(e) Effluent limitations are promulgated for the point sources covered by this General Permit;

The issuance of this General Permit does not prohibit the Permit Issuing Authority from reopening
and modifying the General Permit, revoking and reissuing the General Permit, or terminating the
General Permit as allowed by the laws, rules, and regulations contained in Title 40, Code of Federal
Regulations, Parts 122 and 123; Title 15A of the North Carolina Administrative Code, Subchapter
2H .0100; and North Carolina General Statute 143-215.1 et al. After public notice and opportunity
for a hearing, the General Permit may be terminated for cause. The filing of a request for a General
Permit modification, revocation and reissuance, or termination does not stay any General Permit
condition. The COC shall expire when the General Permit is terminated.
I-8. Certificate of Coverage Actions
Coverage under the General Permit may be modified, revoked and reissued, or terminated for cause.
The notification of planned changes or anticipated noncompliance does not stay any General Permit
condition [40 CFR 122.41(f)].
I-9. Requirement to Report Incorrect Information
Where the permittee becomes aware that it failed to submit any relevant facts in a NOI to be
covered under this General Permit, or submitted incorrect information in that NOI application or in
any report to the Director, it shall promptly submit such facts or information [40 CFR 122.41(1) (8)].
I-10. Waivers from Electronic Reporting
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.
To obtain a temporary electronic reporting waiver, the permittee must first submit an electronic
reporting waiver request to the Division. Requests for temporary electronic reporting waivers
must be submitted in writing to the Division for written approval at least sixty (60) days prior to
the date the facility would be required under this permit to begin submitting monitoring data and
reports. The duration of a temporary waiver shall not exceed 5 years and shall thereupon expire.
At such time, monitoring data and reports shall be submitted electronically to the Division unless
the permittee re -applies for and is granted a new temporary electronic reporting waiver by the
Division. Approved electronic reporting waivers are not transferrable. Only permittees with an
approved reporting waiver request may submit monitoring data and reports on paper to the
Division for the period that the approved reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the Division's website.

published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as
Amended, and Regulation 40 CFR 136.
To meet the intent of the monitoring required by this General Permit, all test procedures must
produce minimum detection and reporting levels and all data generated must be reported down to
the minimum detection or lower reporting level of the procedure. If no approved methods are
determined capable of achieving minimum detection and reporting levels below the General Permit
discharge requirements, then the most sensitive (method with the lowest possible detection and
reporting level) approved method must be used.
I-14. Availability of Reports
Except for data determined to be confidential under NCGS 143-215.3(a)(2) or Section 308 of the
Federal Clean Water Act, 33 USC 1318, all reports prepared in accordance with the terms shall be
available for public inspection at the offices of the Division. As required by the Act, analytical data
shall not be considered confidential. Knowingly making any false statement on any such report may
result in the imposition of criminal penalties as provided for in NCGS 143-215.613 or in Section 309

Total Event Precipitation (inches):
All permits require qualitative monitoring to be performed during a "measurable storm event."
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 Office.
