BEST MANAGEMENT PRACTICES
6.1 Best Management Practice Assessment Process
The facility has considered and implemented practical BMPs. This sub -section describes the
process used to select the BMPs listed in this SPPP as well as provides further description of
purpose and intent of the BMP. Potential stormwater pollution is controlled through the use of
BMPs. BMPs are generally divided into two categories:
Baseline BMPs - which are general in nature (e.g., good housekeeping) and apply to most
industrial facilities, and
Site -Specific BMPs - which pertain to a specific facility (e.g., construction of a concrete
containment around an individual fuel tank).
NCDENR and USEPA emphasize the establishment of pollution prevention measures and
BMPs that reduce the potential for pollutant discharges at the source. Source reduction
measures include preventative maintenance, chemical substitution, spill prevention, good
housekeeping, pollution prevention training, and proper materials management. Where such
practices are not appropriate to a particular source or do not effectively reduce pollutants in
stormwater discharges, NCDENR and USEPA support the use of source control measures and
BMPs such as material segregation, or covering, debris control, vegetative filter strips,
infiltration and stormwater detention or retention, runoff diversion, and dust control. Like source
reduction measures, source control BMPs are intended to keep pollutants out of stormwater.
The remaining classes of BMPs, which involve recycling or treatment of stormwater, allow the
reuse of stormwater or attempt to lower pollutant concentrations prior to discharge.
6.2 Stormwater Pollution Prevention Training
The permit requires that facility personnel receive training on the permit and SPPP compliance,
pollution prevention and spill response. The permit does not specify exact course content or
format. The facility can develop the training programs as it sees fit; however, it is important to
note that stormwater pollution prevention training is the most crucial BMP for the facility to
implement.
6.3 Good Housekeeping Program
Good housekeeping is the preservation of a clean and orderly work environment that
contributes to overall facility pollution control efforts. The implementation of this program may
also include some materials management practices as they relate to storage of drums and
bench stock in the shop areas. Adherence to the following practices will minimize the potential
for stormwater pollution:
• Maintain dry and clean floors as much as possible. Interior floors will be vacuumed after
tasks and weekly, with powder residue placed in designated containers for recycling.
Spills/ drips/ leaks will be cleaned promptly.
• Contaminated dry granular absorbents will be swept daily and disposed properly as will
absorbent pads and other materials.
Trash will be picked up on a regular basis and disposed properly.
Catch basins and other inlets to the,stormwater drainage system will be checked
regularly. Litter and trash will be removed and disposed properly.
The exterior grounds will be policed regularly. Litter and other trash will be disposed

properly. Scrap parts and empty drums will be removed from the facility promptly.
Dumpsters and recycle bins will be covered to prevent precipitation from coming in
contact with container contents.
Equipment will be visually inspected for leaks and other conditions that could lead to a
discharge of a pollutant. Dust collectors will be visually inspected to make sure material
containers are secured and no materials have escaped the systems.
• Hazardous substances will be stored in approved containers. The containers will be
stored in an area not exposed to stormwater. The containers will be located away from
direct vehicular traffic.
Oil and hazardous substance containers will be placed on spill containment pallets or
racks to prevent corrosion and contain leaks. Pallets will be stored as to minimize
exposure to precipitation.
• Tanks, drums, and containers of chemicals and other compounds or mixtures will be
labeled with name of substance, stock number, expiration date, health hazards, safe
handling requirements, and first aid information, as appropriate.
Good housekeeping procedures will be included in the employee training program.
6.4 Preventative Maintenance Program
As part of its preventative maintenance program, the facility regularly inspects and tests facility
equipment and operational systems whose failure has a potential to release pollutants into the
stormwater drainage system. Preventative maintenance inspections may uncover conditions
such as cracks or slow leaks that could cause breakdowns or failures that result in discharges of
chemicals or particulate matter (solids) to the stormwater drainage system. The preventative
maintenance program will reduce breakdowns and failures by making proper adjustments,
repair, or replacement of equipment or parts.
Standard operating procedures include two specific preventative maintenance periods:
• Run-time preventative maintenance occurs daily during working hours as normal
operation of the equipment and machinery.
• Preventative maintenance at regularly scheduled intervals that involve inspections,
cleaning, and minor repairs.
The following items, if present at the facility, are subject to periodic inspections as they have a
direct risk to stormwater. The permit requires written documentation of scheduled inspections.
Fuel Pumps: Items such as the hoses, nozzles, electrical components, and gauges will
be checked for wear. During routine maintenance, facility personnel will adjust and
replace items as needed.
• Oil pumps: Drip containment devices will be inspected for proper operation. Seals,
couplings, and valves will be inspected and replaced as needed. Oil pumps will be
inspected regularly.
• Other Pumps: These devices are subject to frequent inspection and maintenance that,
includes lubrication, balancing, repacking bearings, and tightening of support bolts and
pipe connections. The pump manufacturers' recommendations will be followed. Pumps
that handle hazardous substances with a reasonable potential to pollute stormwater will
be inspected regularly.

Mobile Equipment: These machines will be inspected for leaking hydraulic fluids, fuel
lines, liquid asphalt, and lubricating oils. Mobile equipment will be inspected regularly.
Secondary containment structures: Rainwater that accumulates in any open
containment systems is typically removed by using manual pumps. Discharges will be
made in accordance with the permit and other applicable regulations. The inspector will
observe the structural integrity and look for signs that the primary tank may be leaking.
Exposed secondary containment structures will be inspected regularly. For some storm
events, the rainwater that accumulates in the secondary containment structures may be
dispersed through evaporation or to the on -site wastewater pretreatment system. The
permit does not require the installation of a drain valve where none exists. However,
accumulated residue must be removed and disposed properly.
• Pipes and supply lines: Pressurized petroleum/ oil/ lubricant or other hazardous
substances supply pipes will be inspected regularly. Special attention will be made to
supports, connectors, couplers, and valves.
• Other: Equipment used for recycling various compounds will be inspected and
maintained as directed by the original manufacturer. Other equipment that presents a
reasonable risk for stormwater pollution will be inspected regularly.
• Stormwater Control Measures: Preventative maintenance also pertains to
stormwater control measures such as detention facilities (e.g. on -site wet detention
basin), infiltration devices, diversion structures, and other stormwater treatment
systems. Stormwater control measures must be kept in proper operating condition.
6.5 Spill Prevention and Response
The permit requires that the facility have a spill prevention and response component to the
SPPP document. Spill prevention and response actions are detailed more explicitly in the
facility's SPCC Plan. Spill prevention and response information and procedures will be kept at
the SPPP Team Leader's office and any other appropriate location. The potential spill sources
with high risk for contaminating stormwater include the bulk storage and handling of chemicals,
oil, and other hazardous substances and loading/unloading activities at the facility. Accidents
and careless handling during these activities can cause spilled liquids to enter the stormwater
drainage system. Spill contingencies for high risk spills are described in the SPCC Plan.
Spill Prevention
During transfer or delivery of hazardous substances to facility areas, the driver and handlers will
be responsible for preventing spills. The driver will ensure that all hoses are secure and that
proper absorbent materials are available before unloading. During delivery operations, the driver
will remain with the delivery vehicle at all times. Absorbent pads and booms are to be located
near the delivery/ connection points.
Employee awareness is the key to an effective spill prevention and response program. Spill
prevention training will be a component of the general employee training program. New
personnel will be taught spill prevention practices. Maintenance personnel will gain a sufficient
understanding of the objectives of the spill prevention program. Spill prevention training will
highlight previous spill events, equipment failures, remedies taken, and newly developed
prevention measures.
Spill Response
In case of large volume spills, this facility will request aid from the local fire department.

Additionally, the local emergency management agency may be contacted for assistance to large
volume spills. Minor spills can be absorbed with dry granular absorbents, pads, booms, or
socks. Many liquid materials stored at the facility are used inside buildings or are otherwise not
normally exposed to the storm drainage system. Small spills can be controlled by sweeping or
mopping the material into approved containers for proper disposal. Proper disposal includes
removing absorbent compounds from the floor on a timely basis.
The facility will follow the spill response procedures as outlined in the facility SPCC Plan. Spills
that occur outside on vehicle parking lots or in material/ equipment storage areas may discharge
to the stormwater drainage system. There is always concern about preventing soil
contamination and a concern of preventing any spills from reaching the stormwater drainage
system. The facility will conduct reasonable measures necessary to prevent contamination of
soil or waters of the State.
6.6 Industrial Activity Exposure
The facility takes reasonable measures to minimize the exposure of industrial activities to
precipitation and stormwater run-on_ Measures include'.
Conducting industrial activities indoors or under cover
Storing materials and parts indoors or under cover
Diverting run-on away from the industrial activity area with berms, ditches, curbing,
and buffer strips
• Diverting runoff from industrial activity areas with appropriate runoff management
Methods
6.7 Daily Observations
The SPPP Team Leader, facility supervisors, or other designated personnel, should conduct a
general walk-through of work areas during normal daily duties. A written record is not required
for these daily observations. Particular attention will be made in regards to leaks, spills, and
properly operating equipment. Problems will be reported and corrected as soon as practical.
The following list will serve as a guide to critical items:
Check tanks and drums for leaks, corrosion.
Check secondary containment structures. Drains should be closed and locked.
Look for unusual stains on walls, floors, and grounds.
Look for deterioration of equipment foundations and anchorages.
Check for and remove debris from stormwater drainage system inlets.
Check for windblown materials or materials tracked by vehicles that can enter the
stormwater drainage system.
Is equipment operating properly? Is excessive noise, vibration, or exhaust present?
Is the work area kept in a clean and orderly manner? Practice good housekeeping.
Inspect oil piping. Look for deteriorating gaskets, supports, and loose valve sterns.
Verify that ail valves are in proper position.
Look for leaking containers. Replace as necessary.
Check for torn bags of dry materials or bags exposed to rainwater.

Check that granular absorbents used to contain floor spills are properly cleaned up.
Check condition of spill response kits and quantity of absorbent materials
6.8 Scrap Material Storage
The facility will maintain a program to minimize the quantity of scrap metals, scrap parts, and
unused equipment stored at its facilities. Many of these items have a salvage value or can be
recycled. Procedures for minimizing exposure of scrap and salvage material to stormwater
runoff include:
Remove scrap materials from the facility promptly.
Provide cover for scrap storage areas/bins.
Divert run-on away from scrap storage areas.
Divert runoff from scrap storage areas through a buffer strip, onto a level grassy
area, or into a grass berm.
• Minimize direct runoff into the stormwater drainage system with the use of buffer
strips or other runoff management devices.
Some items present a pollutant risk while they are stored on site. For example, old chemical
tanks may still contain residue. Rusting tanks introduce leached metals into the stormwater
runoff. Abandoned tanks will be emptied and cleaned, and removed from the site. Personnel
will ensure scrap materials are free from lubricants and loose paint to the extent practical.
Personnel will also ensure that salvaged equipment fuel reservoirs are empty and drips are
contained.
6.9 Vegetation Practices
Preserving existing vegetation or re -vegetating disturbed soil as soon as possible after
construction is the most effective way to control erosion.
Vegetation reduces erosion by:
Shields the soil surface from direct erosive impact of rain;
Improves the soil's water storage porosity and capacity so more water can infiltrate into
the ground;
Slows the runoff and allows sediment deposits; and
Physically holds the soil in place with plant roots.
Vegetative buffers (e.g., grass filter strips, forested buffers) improve stormwater runoff quality by
slowing down the rate of flow, trapping sediment, and other pollutants, and increasing infiltration
into the ground. The facility should maintain its vegetative buffers around the facility perimeter to
the extent practical.
Vegetation cover can be grass, trees, shrubs, bark, mulch, or straw. Grasses are the most
common types of cover used for re -vegetation because they grow quickly and provide erosion
protection within days. Straw or mulch may be used during non -growing seasons to prevent
erosion. Retaining existing shrubs and trees helps retain soil because of their established root
systems.

Vegetation and other site stabilization practices can be either temporary or permanent controls.
Temporary controls provide a cover for exposed or disturbed areas for short periods or until
permanent erosion controls are put in place. Permanent vegetative practices are used when
activities that disturb the soil are completed or when erosion is occurring on a site that is
otherwise stabilized.
6.10 Erosion and Sediment Control
Areas where soils are exposed to water, wind, or ice can have erosion and sedimentation
problems. Sedimentation occurs when soil particles are suspended in surface runoff or wind and
are deposited in streams or other water bodies. Construction and other ground surface
disturbing activities can accelerate erosion by removing vegetation, compacting or disturbing the
soil, changing natural drainage patterns, and covering the ground with impermeable surfaces
(pavement, concrete, buildings). When the land surface is impermeable, stormwater can no
longer infiltrate, resulting in larger amounts of water that can move more quickly across a site
and which can carry larger amounts of sediment and other pollutants to streams and rivers.
Stream bank stabilization is used to prevent stream bank erosion from high velocities and
quantities of stormwater runoff. Stream bank stabilization is used where vegetative stabilization
practices are not practical and where the stream banks are subject to heavy erosion from
increased flows or disturbance during construction. Stabilization should occur before land
disturbance commences. Stabilization can also be retrofitted when erosion of a stream bank
occurs.
Areas that are erosion -prone or where construction activity is occurring at the facility will be
inspected regularly. Erosion and sediment control devices will be installed and maintained.
Areas that need immediate erosion repair will be noted in the SPPP. The SPPP (or
SPPPISPCC Site Plan) may also show areas with such heavy activity that plants cannot grow,
material stockpiles, stream banks, steep slopes, construction areas, demolition areas, and any
area where the soil is disturbed, denuded (stripped of plants), and subject to wind and water
erosion.
Ways to limit and control sediment and erosion include:
Leave as much natural vegetation and plants on -site as possible;
Minimize the time that soil is exposed;
Prevent runoff from flowing across disturbed areas - divert the flow to vegetated areas;
Stabilize the disturbed soils as soon as possible;
Slow down the runoff flowing across the site - use level spreaders or terraces;
Provide check dams in drainage ways to decrease flow velocities;
Use grassy swales rather than paved channels; or
Remove sediment from stormwater runoff before it leaves the site by allowing it to sheet
flow through vegetative buffers.
Using these measures to control erosion and sedimentation is an important part of stormwater
management. Selecting the best set of sediment and erosion prevention measures depends
upon the nature of the on -site activities and other local conditions.
6.11 Management of Runoff

Management of runoff is the consideration of appropriate traditional stormwater management
practices (practices other than those which control the source of pollutants) used to divert,
infiltrate, reuse, or otherwise manage stormwater runoff in a manner that reduces pollutants in
stormwater discharges from the site. Procedures determined to be reasonable and appropriate
must be implemented and maintained. The potential of various sources at the facility to
contribute pollutants to stormwater discharges from industrial activity must be considered when
determining reasonable and appropriate measures.
Appropriate measures may include:
• Vegetated buffer zones (maintain grassed/ vegetated areas along facility perimeter)
• Vegetated swales (vegetated depression used to transport, filter, and remove
sediment);
Stormwater diversion devices (grass berms, curbing);
Reuse of collected stormwater (such as for a process or as an irrigation source);
Inlet controls (such as passive sediment interceptors);
Snow management activities;
Infiltration devices; or
Wet detention/ retention basins.
Many BMPs are measures to reduce pollutants at the source before they have an opportunity to
contaminate stormwater runoff. Traditional stormwater management practices can be used to
direct stormwater away from areas of exposed materials/ potential pollutants. Traditional
stormwater management practices can also be used to direct stormwater that contains
pollutants to natural or other types of treatment locations. For example, using grass berms to
divert runoff away from storage yards minimizes the pollutants leaving the site. These
stormwater management practices must be selected on a case -by -case basis depending on the
activities and flow characteristics at the facility.
6.12 Secondary Containment
Secondary containment is provided for bulk storage tanks and drums located at the facility.
Secondary containment can take many forms depending on the types and quantity of
containers, exposure to precipitation, and operation criteria.
Secondary containment should be provided for the following hazardous substance storage
areas:
At bulk oil and chemical ASTs;
Where non -empty 55-gallon drums are stored;
Where drums or other containers are used as dispensing units;
Where paint, solvents, and thinners are stored;
Where oil, liquid pesticides and herbicides, and other hazardous substances are stored.
For ASTs exposed to precipitation, the secondary containment should be constructed of

impervious materials such as poured -in -place concrete. The volume of secondary containment
should equal the volume of the largest AST within the containment plus freeboard for the 25-
year, 24-hour storm event. If a drain valve is provided, the valve must have a lock and remain
closed except when making a controlled release of uncontaminated rainwater. A roof over the
containment will minimize accumulated rainwater.
Other options for ASTs include:
Provide prefabricated tanks with integral secondary containment and rain shed.
Provide double -wall tanks.
Containers in sizes up to 55 gallons (e.g., buckets, cans, drums) have several options:
Store containers inside a prefabricated metal hazardous material storage building with
integral secondary containment.
Use the existing building and provide a built-up curb or berm at the doorway threshold.
Install a ramp to provide access for drums and to prevent trips.
Use the existing building and place a spill blocker across the doorway threshold.
Use the existing building and provide spill containment pallets for the containers.
Build a depressed concrete slab with curbing and a shed roof.
Store small containers within a self-contained flammables cabinet.
Secondary containment that is not exposed to precipitation should have a volume equal to
110% of the largest container within the secondary containment device.
Controlled Releases
Accumulated rainwater can be released from exposed secondary containment structures in
compliance with NPDES requirements. Each release must be documented. Before releasing,
the observer must determine if the accumulated rainwater is contaminated. If contamination is
evident, then the contamination must be removed prior to the release. Uncontaminated
rainwater can be released directly into the stormwater drainage system or onto the ground. In
all cases, document each release. Close and lock the drain valve after the release is completed.
Accumulated sludge in non -exposed secondary containment structures should be
characterized, either by analytical methods or by generator knowledge, and disposed
accordingly.
6.13 Hazardous Substance Management
Hazardous substances stored and handled on the facility have the potential to contaminate
stormwater runoff. The facility will implement the following measures for hazardous substance
storage areas:
a) Store hazardous substances indoors or away from precipitation or stormwater runoff;
b) Provide secondary containment for hazardous substances;
c) Conduct and document regular inspections of the hazardous substance storage area;
d) Place a spill kit near hazardous substance areas to aid in quick response to spills.

e) Label hazardous substance containers properly, Labels will help the employee handle and
use the material safely and respond to spills efficiently.
f) Bulk ASTs of hazardous substances should be labeled with the contents, capacity, and an
emergency telephone number.

Please review the attached N01 application with the objective of responding to me with a recommendation to issue the
permit. I recognize that you may not visit each new permittee during this N01 review, but it affords you the opportunity
to log the permit into your regional database and add the facility to a future monitoring and compliance visit schedule.

Therefore, your recommendation now to issue the permit serves as your acknowledgement4hat (1) the facility is located
in your region, (2) that there are no current complaints outstanding about the facility that have not been dealt with, and
(3) that the facility may ultimately be inspected by the regional staff. I've also attached a scanned copy of the NO1 and a
location map for your review.
