1.0 INTRODUCTION
This document is the Pollution Prevention Plan (hereinafter referred to as the "Plan") developed
for the City of Greensboro Transfer Station (Facility) addressed at 6310 Burnt Poplar Road,
Greensboro, NC 27409. The Facility falls under the jurisdiction of the City of Greensboro's
Municipal Separate Storm Sewer System (MS4) National Pollution Discharge Elimination
System (NPDES) Permit (Permit # NCS000248).
The Cities Permit requires the Permittee to develop site specific pollution prevention plans for
sites that have "...been determined by the permittee to have a significant potential for generating
polluted stormwater runoff' (Part II, Section G.2.(c) of the Cities Permit). The Transfer Station
has been listed as one of these high risk sites.
1.1 Plan Amendment and Annual Review
The Plan shall be reviewed and updated annually. Updates will be made if there is a change in
design, construction, operation, site drainage, maintenance, or configuration of physical features
which may have a significant effect on the potential to pollute surface waters. Findings of the
annual review/update will be maintained in the Pollution Prevention Plan Annual Review Table
located in Appendix A.

City of Greensboro
Location of Facility:
6310 Burnt Poplar Road
Greensboro, Guilford County, North Carolina 27409
Facility Phone #:
336-373-7656
2.1 General Information
The Facility consists of one parcel located south of East Friendly Avenue and is situated
northwest of the intersection of Burnt Poplar Road and South Chimney Rock Road (Figure 1).
The Facility is approximately 9.38 acres in size. Current operations housed at the Facility
include:
• Handling of Municipal Solid Waste (MSW);
• The filling of Above -ground Storage Tanks (ASTs);
• Dispensing of fuel to vehicles and equipment;
• Minor maintenance operations associated with the Facility's equipment; and
• Vehicle and equipment storage.
The Facility lays in a relatively flat area of Guilford County, with a mean site elevation of 915
feet above mean sea level (MSL). Stormwater from the Facility is directed to the on -site
detention basin which feeds into an open channel stemming from the western Facility boundary.
The site map (Figure 2) identifies this channel as well as the property boundaries, site
topography, drainage features, drainage area boundaries, direction of stormwater flow, buildings,
and best management practices (BMPs).
2.2 Facility Description
2.2.1 Storage, Handling, and Disposal Practices of Hazardous Materials
Where possible, materials are stored and handled indoors or under cover and within
secondary containment systems to minimize exposure to rainfall and run-on. Material
handling of potential storm water pollutants is conducted in a manner as to prevent spills.
Storage Practices
Hazardous materials stored at the Facility consist primarily of oils and fuels with the
exception of small quantities of liquid materials such as cleaning supplies. These smaller
quantity materials are bought and used as needed and stored inside the Facility.
The oil/fuel storage at the Facility consists of two ASTs, one mobile refueling AST, and
up to eight 55 gallon drums of maintenance oils including: used oil, motor oil, hydraulic
oil, and gear oil. The two ASTs are located directly southeast of the Facility structure
and contain fuel. The first AST is a 12,000 gallon, double -walled, steel tank that is used
to refuel equipment utilized at the Facility. The second AST is a 1,400 gallon, double
walled, steel tank that is used to fuel the generator that is located atop of the tank. The
2

mobile refueling AST is located near the storage room on the lower level of the Facility
and contains diesel fuel. The mobile AST is 100 gallons in size and is constructed of a
single wall of steel. The 55 gallon drums are stored on top of pallet containment
structures in the storage area on the lower level. The Facility stores approximately eight
drums on -site which are used to conduct minor repairs/maintenance on the Facility's
equipment. A complete material inventory list can be found in Appendix C of the Plan.
The locations of these containers are depicted in Figure 2.
Equipment Associated with Operations
The Facility utilizes various pieces of fuel/oil filled heavy equipment (excavators, front
end loaders, bobcats, and semi -trucks). A majority of this equipment is housed inside the
facilities structure with the exception of two semi -trucks that move trailers to and from
the loading bays. Commercial garbage trucks and residential vehicles continuously enter
and exit the Facility during hours of operation.
Loading and Unloading Activities
The ASTs are filled by a third party petroleum supplier that must meet the minimum
requirements and regulations established by the United States Department of
Transportation (USDOT).
The oil drums are not refilled at the facility. Full 55-gallon drums are dropped off at the
transfer station and moved using the Facility's heavy equipment to the storage area.
Waste Disposal Practices
The sole purpose of the Facility is to facilitate the disposal of MSW. A majority of the
waste handling practices occur on the upper level of the Facility. This is where
commercial waste hauling vehicles deposit their waste for the Facility's operators to
prepare for transport to the landfill. There are also dumpers located outside of the
Facility's structure that are used for residential recycling drop-offs. These dumpsters are
emptied routinely by Facility personnel.
2.2.2 Potential Pollutants
Potential pollutants at the Facility include petroleum hydrocarbons, leachate, and solids
(floating and suspended).
2.3 Significant Spills
Spills will be addressed and documented in accordance with the facilities Spill Prevention,
Control, and Countermeasure (SPCC) plan.

3.0 STORMWATER MANAGEMENT STRATEGY
3.1 Operation Specific Management Strategies
Where practical, operations and storage practices have been established that minimize or
eliminate exposure of materials and processes to rainfall and run-off flows.
3.1.1 Handling of MSW
Interior Operations
MSW is deposited by commercial and residential vehicles. This takes place inside the
upper level of the Facility (drop-off area) where the waste is then moved by heavy
equipment and dropped down two cavities in the floor. These loading pits lead to the
trailer bay located on the lower level. Both the upper and lower levels of the Facility have
a network of drains and curb inlets that collect and surface liquid (water, leachate, oil,
fuel, etc.) and direct it to a 2,000 gallon oil -water separator. Once the liquid has gone
through the separator, it is then sent to the sanitary sewer system.
Exterior Operations
Numerous vehicles traverse the Facility's paved roadways and parking lots on a daily
basis including commercial dump trucks, resident vehicles, Facility equipment, and
trailers that are either filled with waste set to be hauled to the landfill or empty trailers
waiting to be filled.
Should an accident occur involving any of these vehicle or pieces of equipment causing a
spill of hazardous material, it is possible for the substance to enter the Facility's
stormwater system. This system is comprised of various drains and curb inlets that direct
surface water from the exposed areas of the Facility to the site's stormwater basin. Any
spilled material that makes its way to the Facility's stormwater system would then be
captured in the stormwater basin, allowing for remediation activities to take place in
accordance with the facilities SPCC plan. Best efforts will be made to prevent hazardous
material from entering the Facilities stormwater system through the use of Best
Management Practices (BMPs) and good housekeeping measures, further outlined in later
sections of this Plan.
The trailers used for the loading, storage, and hauling of MSW are owned by a third party
vender. The empty trailers enter the Facility and are stationed in the southern parking lot.
They are then brought into the building, filled with MSW, and moved to the same
parking lot before being hauled to a landfill. The time these filled trailers spend in the
parking area varies but, actions are taken in order to prevent leachate from entering the
Facility's stormwater system. These actions include continued maintenance on the
trailers (patching holes), ensuring seals on the back doors are intact, and covering the
trailers with a retractable tarp. Facility personnel also utilize drip pans should they notice
a leak from one of the containers.

3.1.2 Filling of ASTs
The AST loading area is partially paved and uncovered. Should a spill occur in this
location that could not be immediately contained, the excess material would likely flow
into a storm grate west of both ASTs. This grate leads to the sediment basin where the
fuel could be properly remediated. Should a spill occur during filling operations, the
material would remain on -site, allowing for the proper remediation activities to take
place.
3.1.3 Dispensing Fuel to Facility Equipment
The fuel dispensing area is the same as the AST loading area listed in section 3.1.2 and
thus has the same potential exposures. Additional exposure risks are present when
considering the practices associated with the mobile refueler due to its ability to be used
anywhere on the Facility's grounds. However, should a spill occur during fueling
operations, the material would remain on -site allowing for the proper remediation
activities to take place.
3.1.4 Minor Maintenance Operations
Minor repairs performed on the Facility's equipment, as well as the maintenance oil used
to perform these repairs, is conducted and stored inside the Facility's structure. Various
drains and grates cover the interior of the Facility and lead to the oil -water separator.
Should a spill occur during maintenance activities, the material would remain on -site
allowing for the proper remediation activities to take place.
3.1.5 Vehicle and Equipment Storage
A small gravel storage lot is located on the northeastern corner of the Facility. The
storage area is uncovered but the topography of this area directs water to one of the
Facility's curbed stormwater inlet located along the northern most paved road. Should a
spill occur in the vehicle storage area, the material would remain on -site allowing for the
proper remediation activities to take place.

3.3 Pollution Prevention through Best Management Practices
Best management practices (BMP) for the Facility were selected based on the assessment of the
potential for sources to contribute pollutants to the Facility's stormwater discharge. These BMPs
include secondary containment, preventative maintenance, good housekeeping, and employee
training.
3.3.1 Preventative Maintenance
Maintenance of storm water management devices performed as part of this program and
other routine maintenance programs includes the following:
• Cleaning of accumulated sediment and debris from conveyance systems, pipe
lines, and stormwater basin;
• Clearing of debris from drainage features such as curbs, gutters, and ditches;
• Clearing of vegetation that would prevent the visual inspection of the stormwater
basin, emergency cleanup of the stormwater basin, or inhibit the effectiveness of
the stormwater basin outlet structure;
• Preventative maintenance is performed on equipment in conformance with the
manufacturer's recommendations; and
• Maintenance necessary to ensure efficient operation of the storm and sanitary
sewer systems (e.g. monthly maintenance on the trench and floor drains and
oil/water separators).
3.3.2 Facility Inspections and Testing
Visual inspections of the Facility's heavy equipment and storage containers are
completed on a daily basis by the Facility personnel. These inspections are not recorded.
More detailed inspections of the Facility and all stormwater systems will occur every six
months, with one inspection during the first half of the year and one during the second
half of the year with at least 60 days separating the inspections. Completed inspection
logs are filed with the Plan in Appendix D. Inspections of the Facility's ASTs can be
found in the SPCC plan.
Additional inspections of the Facility's bulk storage containers are conducted through the
SPCC Plan. These include monthly visual inspections, semi-annual inspections, and
periodic formal inspections.
3.3.3 Good Housekeeping
Good housekeeping is practiced at the Facility as part of standard operating procedures
and is implemented by all employees. The maintenance of a clean and orderly Facility
maximizes operational efficiency, minimizes employee safety hazards, and reduces
potential pollutant impacts to the storm water conveyance system. Employees are trained
to understand the importance of good housekeeping practices. Housekeeping activities at
the Facility are summarized below.
3

Materials Mana em�ent
Responsible management of common chemicals, such as solvents, paints, cleaners, and
automotive products, includes selection of the products, correct use and storage, and
responsible disposal of associated wastes. Material storage and inventory controls reduce
the occurrence of overstocking hazardous materials. Routine cleaning and inspections of
material storage, process, and disposal areas reduce the likelihood of accidental spills or
releases during storm events.
Vehicle and Equipment Maintenance
All maintenance activities are performed inside or under cover. Spills are cleaned up
immediately, without water whenever possible, and clean up materials are properly
collected and disposed. When water is used, it is directed toward the trench drains that
flow into a pretreatment device (i.e. oil/water separator) prior to discharge to sewer
system.
The outdoor staging areas are inspected regularly for drips and spills by Equipment
Services personnel. Areas traversed by residential vehicles, Facility equipment, and
employee vehicles are monitored as a part of the Facility's regular operation for signs of
leaks or spills.
Proper Fueling of Vehicles and ASTs
During the loading and unloading, or transfer of automotive fluids by a third party
vendor, Facility employees ensure that outside personnel understand the site layout, know
the protocol for entering the Facility and transfer of product, and have the necessary
equipment to respond to a release from the vehicle or fuel delivery hose. A Facility
Manager or designee supervises oil deliveries for all new suppliers and periodically
observes deliveries for existing, approved suppliers. Additionally, both the diesel AST
and the generator AST have high liquid level alarms that are tested on a monthly basis.
Vehicle and equipment filling operations are performed near the AST by City staff
trained in proper spill prevention measures.
3.3.4 Stormwater Basin
A sediment basin that processes a majority of the facilities runoff is located on the
western portion of the property. The purpose of the basin is to improve stormwater
quality primarily by detaining stormwater runoff for an extended period of time to allow
pollutants that are suspended in the runoff to settle out. It also has the ability to trap
fugitive material that may be spilled on the exterior pavement that encompasses the
Facility.
3.3.5 Employee Training
The municipal employee training program is designed to teach staff about potential
sources of storm water contamination and ways to minimize the water quality impact of
7

municipal activities. The training program includes a general storm water awareness
message; pollution prevention/good housekeeping measures; the BMPs utilized at the
Facility; and the Plan for this Facility. Training records regarding spill prevention and
response can be found in Appendix F of the Facility's SPCC plan.
3.3.6 Stormwater System Maintenance
Regular maintenance of the storm water structures (e.g. stormwater basin and
curb/gutters) will reduce the amount of sediment and other pollutants that can potentially
migrate into the Facility's stormwater management system and downstream receiving
waters.
3.3.7 Used Oil Recycling Procedures
Used oil recycling is utilized at the Facility to encourage and facilitate proper
management of used oil. This reduces the likelihood of storm water impacts by
encouraging the capture of all used oil generated at the Facility
3.3.8 Material Exposure Controls
Where practical, operation and storage areas have been covered to minimize or eliminate
exposure of materials and processes to rainfall and run-off flows.
3.3.9 Spill Prevention and Cleanup
Active and passive spill containment measures are utilized at the Facility to prevent
spilled materials from migrating outside the industrial activity area and/or into surface
waters.
3.3.10 Secondary Containment
The two diesel ASTs are constructed using a double walled design. This is intended to
allow for the contents of the containers to be completely contained by the outer wall
should the inner wall rupture. Additional secondary containment is provided by spill kits
located near the ASTs.
The drums and portable refueling tank are stored inside the maintenance/storage area
located on the lower level of the Facility. Both the drums and the portable refueling tank
have spill kits readily accessible in the event of a leak or spill. The drums are also stored
atop containment pallets that are adequately sized to contain the contents of the drums.
All secondary containment located at the Facility complies with the applicable standards
outlined in its SPCC plan.

4.0 SPILL PREVENTION, CONTROL, AND COUNTERMEASURE PLAN
The facilities Spill Prevention, Control, and Countermeasure (SPCC) plan outlines the practices
associated with the use and disposal of oils on -site. The SPCC plan can be found in Appendix B.
