Inspection Summary:
This facility performs vehicle maintenance, however the facility uses less than 55 gallons of new motor oil per month so
does not need to do analytical monitoring. The facility has an oil water seperator that drains to the sanitary sewer so does
not trigger analytical monitoring. The stormwater pollution prevention plan and all monitoring is complete.

StorrnwaterPollution Prevention Plan ii

1.0 INTRODUCTION
This Stormwater Pollution Prevention Plan (SWPPP) has been prepared to comply with the United
States Environmental Protection Agency (EPA) National Pollutant Discharge Elimination System
(NPDES) program under the amended 1977 Federal Water Pollution Control Act. This SWPPP:
(1) consists of steps and activities designed to identify potential sources of stormwater pollution or
contamination and (2) establishes Best Management Practices (BMPs) that will prevent or reduce
pollutants in stormwater runoff. This SWPPP has been prepared in accordance with standard
engineering practices.
Existing stormwater management practices required by other existing environmental management
plans have been evaluated and applicable portions have been incorporated into this SWPPP.
Future stormwater management practices required by other regulations will be evaluated by the
Environmental Office and incorporated into the SWPPP as required.
The Plan is formatted like an Army Technical Manual, with easy -to -follow procedures and plenty
of visual cues. For quick reference, look on the front cover to see what chapter contains the
information you need and then flip to that chapter. Or, simply use the 1%ble of Contents to look
up a specific subject, table or map.
1.1 Regulatory Obligations
The North Carolina Department of Environment and Natural Resources (DENR), Division of
Water Quality (DWQ), has adopted final stormwater permitting rules for industrial discharges in
North Carolina. North Carolina is a delegated NPDES state with general and individual permitting
authority. EPA regulations 40 CFR 122 require certain industries to apply for an NPDES Permit
for stormwater discharges. The required industries must characterize and monitor storm drainage
areas and stormwater quality and must also perform BMPs, if necessary, that include operational
(or source controls) and structural practices. This North Carolina Army National Guard
(NCARNG) facility is covered by NPDES General Permit No. NCGO80000 which expires August
31, 2007. Section 8 contains for a copy of the certificate of coverage for this facility. The permit
certificate of coverage (COC) for this facility is effective 1 September 2002. A copy of the NPDES
General Permit can be obtained through the Environmental Office.
1.2 Key Facility Personnel and Responsibilities
Stormwater regulations require facilities to form a Stormwater Pollution Prevention Team. This
team, along with other key personnel, will oversee the facility's stormwater pollution prevention
program. This section gives information concerning the responsibilities of'key personnel as well
as instructions for the Stormwater Pollution Prevention Team and other facility personnel involved
in activities affecting stormwater quality.
1.2.1 . Stormwater Pollution Prevention Team
The Stormwater Pollution Prevention Team (SWPPT) consists of facility supervisors and other
appropriate personnel. The Facility Environmental Coordinator (FEC) will serve as the SWPPT
Leader. The SWPPT will need to meet to evaluate the effectiveness of the BMPs and the
SWPPP where changes to the facility affect the potential risks to stormwater quality. These
t
North Carolina Arm v National Guard
Stormwater Pollution Prevention Plan

revisions will be simple and brief and inserted as amendments to the original SWPPP. Form 2,
Review and Amendment Certification, in Section 5 will be used to document amendments.
The purpose of the SWPPT is to:
r Review SWPPP and amend if changes to the facility necessitate a plan amendment
Train facility staff on SWPPP requirements
r Implement Best Management Practices
r Conduct fall and spring site inspections
0- Conduct visual observations of stormwater outfalls in fall and spring
Inspect and document any rainwater releases from secondary containment structures

1.2.2 Facility Personnel
Facility personnel involved in any of the facility's operations that have the potential to contaminate
stormwater runoff are required to learn proper spill response and cleanup procedures and
preventative maintenance activities. Such personnel are required to:
-1i Learn stormwater pollution prevention procedures and requirements
Establish spill containment procedures, drainage control, and security measures
4 Follow established procedures for hazardous waste and material management
4� Perform routine inspections
wl� Maintain records to document successful completion of SWPPP requirements
The FEC shall be responsible for ensuring that the required SWPPP tasks and appropriate
documentation is completed, signed and dated. The FEC will also conduct an annual
procedural and technical review of the SWPPP, including an evaluation of structural BMPs.
The FEC will amend the SWPPP whenever there is any change in facility design, construction,
operation or maintenance which has an effect on the potential for stormwater contamination.

2.0 FACILITY LOCATION AND OPERATIONS
This section gives information on the facility and its operations, its location, drainage and the
operational risks to the facility's stormwater drainage system. This section fulfills the NPDES
Permit requirement to include a narrative description of the physical facility and potential
stormwater pollutant sources. This section does not contain any requirements for the FEC
or SWPPT.
2.1 Facility Industrial Activity
This facility is considered to have stormwater discharges in the following industrial categories:
Vehicle Maintenance
Stormwater discharges covered in this category include runoff from areas where the following
maintenance activities may occur: fluid changes; mechanical repairs; parts cleaning; washing;
storage of vehicles and equipment waiting for repair or maintenance; and storage of the related
materials and waste materials such as oil, fuel, batteries, tires, or oil and fuel filters.
POL/Hazardous Materials Storage
Storage areas for new and waste materials such as oil, batteries, tires, and filters are included
when the storage areas are either directly exposed to rainfall or when spills or leaks from these
areas have the potential to enter the storm drainage system.
2.2 Facility Location
The Asheville Armory and Organizational Maintenance Shop (OMS) #1 is located within the City
of Asheville, approximately three miles southwest from the City's central business district. The
NCARNG operates and maintains approximately ten acres at this location. The facility is
bounded immediately to the south by Shelborne Road and Brevard Road. The surrounding
properties include residential on the north and east sides, and a highway interchange on the
south and west sides of the Guard property. Map 1 shows the location of the Asheville facility.
2.3 Facility Description
The activities performed at the Asheville facility include military training, maintenance and repair
of tactical vehicles and equipment and hazardous materials storage. The layout of the facility is
shown in Map 2. The site map identifies building locations, the stormwater drainage system,
industrial waste systems, potential pollution sources, and outfalls.

and the AST fuel funnel is kept locked.
A wash pad located south of the shop consists of a concrete containment pad sloped to a
central drain which discharges through an adjacent oil/water separator (OWS) to the sanitary
sewer system.
Small amounts of hazardous wastes (e.g., weapons cleaning patches) and used POLs may be
generated during drills and brought to this facility from other Armories. Small amounts of
hazardous wastes and used POLs are generated by this facility. Such materials are stored in
the CAP until transported off -site and disposed.
The facility operates a recycling station for aluminum, plastic, glass, metals, and paper. The
station is under a shed roof and is located south of the OMS.
Armory
The Armory consists of a drill hall (with boiler room, mechanical room, administrative offices
and classrooms), several dry storage buildings, tactical vehicle parking and POV parking. The
Armory building contains a supply room, which typically stores infantry clothing and equipment
and janitorial cleaning supplies. A spill kit is located in the mechanical room. Floor drains in the
Armory are connected to the sanitary sewer system. This building does not represent a
significant source of potential stormwater pollutants.
Several dry. storage buildings associated with the Armory are located in the western parking lot.
A self-contained flammables cabinet used to store small quantities of paints, aerosols, cleaners,
and solvents is located inside a storage trailer located in this area. Hazardous materials are not
stored in the other dry storage buildings.
Two USTs containing heating oil are located outside the Armory. A 500-gallon UST is located
north of Armory Battalion Addition and a 6,000-gallon UST is located west of the Armory. The
North Carolina Army National Guard 7
Stamwater Pollution Prevention Plan

fuel ports associated with each UST are kept locked. These USTs will be removed when the
facility converts to natural gas heating.
On June 9, 2001, a truck ambulance spilled approximately four (4) gallons of diesel fuel that
was left in a five -gallon container inside the ambulance. OMS personnel removed the fuel can
and cleaned up the area under the vehicle and properly disposed of the contaminated soil.
There have been no other significant spills at the facility site since July, 1995.
2.4 Facility Drainage
The facility is located in the Blue Ridge province of the Appalachian Highlands physiographic
region. Soils at the facility are in the Evard-Porters-Urban land complex, which is a loam. The
site has been altered significantly with cut and fill, particularly west of the OMS. Typically, the
soils in the vicinity of the facility are well drained, have a moderate permeable (2.0 to 6.0 inches
per hour) surface layer and a less moderately permeable (0.6 to 2.0 inches per hour) subsoil.
Runoff is moderate to rapid (Soil Survey of Buncombe County, USDA, 1954).
The topography across the site slopes toward the south and west. In the vicinity of the Armory,
slopes exceed ten percent. Most spills in the motorpool area greateAthan five gallons would
probably enter the adjacent ditches and subsequently waters of the State. There is no runoff
from other industrial facilities onto the facility site. However, a spill on Shelborne Road or
Brevard Road could flow onto Guard property.
Runoff from a residential area north of the facility previously caused erosion problems across
the lower military parking area. The facility parking lot was unpaved and cut with eroded
channels (other banks with such cuts on the Guard property have minimal or non-existent
vegetative covering and are subject to erosion problems). Severe erosion was present
throughout the lower west OMS vehicle parking area. The facility is located on the east bank of
an unnamed tributary to Hominy Creek. The site is in the French Broad River Basin.
Most runoff from the site leaves as sheetflow. In effort to improve site drainage, a rip -rap ditch
was installed in December of 1998 along the north end of the facility property that directs run-off
from the residential area to Shelborne Creek. This ditch is located outside of the facility's fence
line and runs from the north end of the property to a 10,000 gallon -capacity accumulation pond
located at the south end of the property. This accumulation pond will catch run-off from the
residential area and from the OMS and Armory parking lots. Pond water runs to Shelborne Creek
via corrugated metal pipe that is equipped with a valve that can be shut off in the event of a POL
or hazardous materials spill on the facility's property.
Three industrial outfalls are present at this facility. Stormwater Discharge Outfall 001 (SDO-001)
contains runoff from the a portion of the OMS area, the northern portion of the Armory, POV
parking, and off -site drainage. SDO-002 contains runoff from POV parking and the Armory.
SDO-003 contains runoff from the Armory.
The industrial drainage outfalls are identified in Table 2. The approximate location of these
outfalls (defined here as point source discharges of stormwater to "waters of the State") are also
shown in Table 2. Stormwater discharge monitoring will be performed at the designated outfall
points as indicated on Map 2.

2.5 Facility Risk Assessment
The operations that have a risk of contributing to a large spill which may contaminate the
stormwater drainage system at the facility are the delivery and transfer of fuel at the OMS
refueling area and the delivery, transfer and handling of POLs and/or hazardous substances
stored on -site. There is a risk of minor spills in the vicinity of the vehicle parking and POL storage
areas. Such minor spills can be from paint, lubricating oils, fuel, cleaning compounds, and brake
or other hydraulic fluids. Other risks are minor as most other operations take place inside
buildings. Materials subject to long term exposure to precipitation represent a low-level risk of
stormwater pollution.
Table 3 describes the significant materials that were exposed to stormwater during the past
year and/or are currently exposed. Significant materials include, but are not limited to, raw
materials, fuels, solvents, detergents, metals, hazardous substances, fertilizers, and waste
products that have a potential to be released with stormwater discharges.

3.0 FACILITY BEST MANAGEMENT PRACTICES
Potential stormwater pollution is controlled through the use of BMPs. Consequently, the
stormwater NPDES Permit requires that facilities consider and complete BMPs. This section
gives information on BMPs appropriate for your facility. Non-structural (or procedural) BMPs
described in this section include good housekeeping, equipment inspections, spill prevention and
response, vehicle cleaning, and refueling operations. Structural BMPs described in this section
include secondary containment, oil/water separators, vegetative practices, and stormwater
management devices.
3.1 Good Housekeeping
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: „
—► Hazardous substances will be stored in approved containers as per HMWMP guidelines.
The containers will be stored in an area not exposed to stormwater. The containers will be
located away from direct vehicular traffic.
�► Containers of chemicals and other compounds or mixtures will be labeled with name of
substance. For each chemical substance used, a Material Safety Data Sheet (MSDS) will
be provided in areas accessible to personnel.
�► Brooms, dustpans, and mops will be hung on racks for easy access and use.
�► Maintain dry and clean floors. Interior floors will be swept weekly, with residue placed in
designated waste disposal containers.
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 of properly.
Separate holding containers will be provided for oily rags as a fire prevention aid.
�► The exterior grounds will be policed regularly. Litter and other trash will be disposed
properly. Scrap parts and drums will be removed from the facility promptly.
Contaminated dry granular absorbents (e.g., "speedi-dri") will be swept daily and disposed
of properly.
r+ Drums and tanks containing used oil must be labeled "USED OIL."
Dumpsters and recycle bins will be kept covered with a lid or tarp to prevent rainfall from
coming in contact with container contents.

—+ Good housekeeping procedures will be included in the employee training program.
Regularly scheduled meetings will be held to discuss good housekeeping and pollution
prevention concepts.
3.2 Preventative Maintenance
The facility shall regularly inspect and test facility equipment and operational systems.
Inspections will uncover conditions such as cracks or slow leaks which could cause breakdowns
or failures that result in discharges of chemicals or particulate matter (solids) to the storm drain.
The 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:
O Run-time preventative maintenance occurs daily during each shift as normal operation of
the equipment and machinery.
© Preventative maintenance during weekend drills will involve inspections, cleaning, and
minor repairs.
At the beginning of each day, a general walk-through of all work areas should be conducted by
the FEC or other designated personnel. A written record is not required for these daily
observations. Problems should be reported and corrected as soon as practical.
The following items, if present at the facility, are subject to periodic inspections as they have a
direct risk to stormwater, though many of the items are currently inspected on a regular basis as a
requirement of the NCARNG HMWMP or SPCC plans. Your facility's stormwater NPDES permit
requires written documentation of scheduled inspections. Retain inspection records for 5 years.
d Fuel Pumps: Items such as the hoses, nozzles, electrical components, and gauges will
be checked for wear. 4Routine maintenance will adjust and replace items as needed.
d Oil Pumps: Drip containment devices will be inspected for proper operation. Seals,
couplings, and valves will be inspected and replaced as needed.
d 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.
d Mobile Equipment: These machines will be inspected for leaking hydraulic fluids, fuel
lines, and lubricating oils.
d Secondary Containment Structures: These structures will be equipped with a locking
valve controlling discharge. The valves will be locked in the closed position. Discharges
will be made in accordance with the NPDES Permit and other applicable regulations. The
inspector will observe the structural integrity, valve and lock operation, and look for signs
that the primary tank may be leaking.

reasonable risk for stormwater pollution will be inspected and repaired as needed.
3.3 Spill Prevention and Response
The NPDES Permit requires that the NCARNG develop a spill prevention and response addition
to the SWPPP and that appropriate personnel are trained in spill response procedures. Every
facility has the NCARNG Hazardous Materials Waste Management Plan (HMWMP) and an
Installation Spill Contingency Plan (ISCP). Some NCARNG facilities are also required to have a
Spill Prevention, Countermeasure and Control Plan (SPCCP) as well. Spill response actions are
detailed more explicitly in either the Installation HMWMP or in the facility's SPCCP, if the facility is
required to have one. Spill prevention and response information and procedures are kept at the
FEC's office and at each shop location. The storage and handling of fuels and vehicle
maintenance are the potential spill sources that pose the greatest risk for contaminating
stormwater. Accidents and careless handling during these activities can cause spilled liquids to
enter the storm drain system.
The ARNG has prepared an Oil Spill Prevention and Contingency Plan (OSPCP) for all ARNG-
owned mobile fuel handlers. Large capacity mobile fuel tankers must maintain a copy of the
OSPCP in each tanker.
Spill Prevention: During transfer of fuel to a facility, the driver and handlers will be responsible
for preventing spills. The driver will:
�°► Ensure that all hoses are secure
—► Ensure absorbent materials (pads and socks) are available before unloading
�► Remain with vehicle during all fuel delivery operations
�► Ensure absorbent pads and booms located near the fuel delivery/ connection points
Spill Response: The facility will follow spill response procedures as outline in the facility SPCC
Plan and/or HMWMP. In case of large volume spills, this facility will request aid from the local Fire
Department. Minor spills can be absorbed with clay filler, pads or booms. 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.
This facility does not use any extremely hazardous substances, but certain precautions regarding
other materials are necessary. Spills that occur outside on paved vehicle parking lots may
discharge to the storm drain system. There is always concern about preventing soil
contamination and a concern of preventing any spills from reaching the storm drain system.
Reasonable measures necessary to prevent contamination of soil or waters of the State will be
carried out. In general, there are four basic steps, which are to be taken to control pollution that
can result from a spill:
O Stop the spill at the source.

© Contain the spill.
© Collect the spilled material.
O Dispose of the spilled material and subsequent contaminated material properly and legally..
If containment methods are required for which you are not trained, or personal protective
equipment is not available, immediately evacuate the contaminated area and prevent
unauthorized personnel from entering. Steps 3 and 4 should only be undertaken by personnel
that are properly trained in spill response and cleanup.
3.4 Vehicle and Equipment Cleaning Areas
The NPDES Permit has requirements for the facility to establish measures to prevent the
discharge of washwater to the storm drainage system to the maximum extent practicable. The
facility will ensure that all wash waters discharge in accordance with the NPDES Permit. If a
sanitary sewer system is not available to the facility and cleaning operations take place outdoors,
the cleaning operations shall take place on grassed or graveled areas to prevent point source
discharges of the washwater into storm drains or surface waters. Where cleaning operations
cannot be performed as described above and when operations are performed in the vicinity of a
storm drainage collection system, the drain is to be covered with a portable drain cover during
cleaning activities. Any excess ponded water shall be removed and properly handled by pump to
a sanitary sewer system prior to removing the drain cover. Detergents shall be biodegradable and
the pH adjusted to be in the range of 6 to 9 standard units.
The following methods are recommended to prevent or minimize contamination of the stormwater
runoff from areas used for vehicle and/or equipment cleaning operations:
• Perform all cleaning operations indoors
• Provide cover for outdoor cleaning operations
• Ensure all washwater drains to the sanitary sewer system
• Collect stormwater runoff from cleaning areas and provide treatment or recycling
• Other equivalent measures
The point source discharge of vehicle and equipment washwater, including tank cleaning
operations, is not authorized by this NPDES Permit and will be covered under a separate NPDES
general or individual permit or discharged to a sanitary sewer in accordance with applicable local
industrial pretreatment requirements.
3.5 On -site and Remote Refueling Operations
If refueling operations are mission applicable for the facility, the NPDES Permit has
requirements for the facility to implement BMPs at on -site fuel stations and remote refueling
activities located off -site but under the control of the facility. Refueling activities may occur at the
facility during normal duty hours or prior to or during weekend drill activities. The following BMPs
will be performed to prevent or minimize contamination of the stormwater runoff from such
activities:
�► Instruct personnel to avoid "topping off' the fuel tanks
�► Instruct drivers of bulk tankers to remain with vehicle during entire fuel delivery process
Provide drip pans at refueling locations and with refuelers to collect small leaks

•4 Provide spill kit at refueling locations and with each refueler
`4 Minimize outdoor refueling operations during times of heavy rainfall
•°+ Provide secondary containment (i.e., portable berms) for mobile fuel tankers and storage
tanks located at remote refueling areas as required
If remote refueling (or other vehicle maintenance activities) are conducted at off -site locations, the
above -listed BMPs will be performed to prevent or minimize contamination of stormwater runoff
from these areas. Additionally, the ARNG has prepared an OSPCP for ARNG-owned mobile fuel
tankers. Large capacity mobile fuel tankers stored at the facility must maintain a copy of the
OSPCP in each tanker.
3.6 Industrial Activity Exposure
The facility will take reasonable measures to minimize the exposure of industrial activities to
precipitation and stormwater runoff. 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
The NPDES Permit does not require that vehicles, equipment or inert materials such as wood,
pipe, or aggregate be placed under cover.
3.7 Secondary Containment
The NPDES Permit requires that secondary containment be provided for bulk storage (of
liquids, other than mobile fuel tankers), storage of water priority chemicals, and hazardous
substance storage to prevent leaks and spills from contaminating stormwater runoff. Refer to
Emergency Planning and Community Right -to -Know Act (EPCRA) Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) for a list of water priority chemicals.
Secondary containment can take many forms depending on the types and quantity of
containers, exposure to precipitation, and operation criteria.
Secondary containment should be considered:
• At ASTs, including ASTs containing fuel, used oil, and heating oil
• Where non -empty 55-gallon drums are stored
• Where drums or other containers are used as dispensing units within workshops
• Where paint, solvents, and thinners are stored
• Where POLs are stored
• Where other liquid 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
North Carolina Army National Guard 15
Stormwater Pollution Prevention Plan

closed except when making a controlled release of uncontaminated rainwater. See Section 4
for instructions on the proper procedures for releasing rainwater from secondary containment
structures. A roof over the containment area 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, jerricans, drums) have several options:
• Store containers inside a prefabricated metal HAZMAT 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 cabin%
Secondary containment that is not exposed to precipitation should have a volume equal to
110% of the largest container within the secondary containment device.
3.8 Hazardous Substance Storage and Management
For purposes of this section, the term hazardous substance includes hazardous substances
defined by USEPA, hazardous materials defined by federal DOT rules, regulated hazardous
wastes, non -regulated wastes, and any other material or substance that is a reasonable
potential stormwater pollutant. Hazardous substances shall be managed at the facility in
accordance with the NCARNG HMWMP.
The facility has the following options for hazardous substance storage:
• Store hazardous substances indoors within secondary containment
• Store hazardous substances outdoors under cover and within secondarycontainment
• Store hazardous substances in a prefabricated HAZMAT storage building with integral
secondary containment
• Store small hazardous substance containers in a flammables cabinet with integral
secondary containment
Provide a spill kit near or at locations where hazardous substances are stored. The spill kit
should consist of absorbent pads, booms, and/or dry granular absorbents in sufficient quantity
to contain a spill from the largest container at that storage location. Non -sparking shovels and
a container for disposing of the used absorbents should be available to aid in spill cleanup.
Ensure that hazardous substance containers are labeled properly according to the NCARNG
HMWMP. Labels will help personnel handle and use the material safely and respond to spills
efficiently.

closed except when making a controlled release of uncontaminated rainwater. See Section 4
for instructions on the proper procedures for releasing rainwater from secondary containment
structures. A roof over the containment area 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, jerricans, drums) have several options:
• Store containers inside a prefabricated metal HAZMAT 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.
3.8 Hazardous Substance Storage and Management
For purposes of this section, the term hazardous substance includes hazardous substances
defined by USEPA, hazardous materials defined by federal DOT rules, regulated hazardous
wastes, non -regulated wastes, and any other material or substance that is a reasonable
potential stormwater pollutant. Hazardous substances shall be managed at the facility in
accordance with the NCARNG HMWMP.
The facility has the following options for hazardous substance storage:
• Store hazardous substances indoors within secondary containment
• Store hazardous substances outdoors under cover and within secondary containment
• Store hazardous substances in a prefabricated HAZMAT storage building with integral

Stormwater Pollution Prevention Plan

3.9 Oil/ Water Separators
Oil/ water separators (OWSs) are designed to trap oil and other pollutants that float on the
surface of water. To operate properly, OWSs require frequent and intense maintenance and
the regular removal of accumulated oily sludge and grit. The introduction of detergents, acids,
heavy pollutants, and soluble materials will render the OWS ineffective. OWSs are not typically
designed to treat stormwater; therefore, a large flow of stormwater runoff through an OWS will
cause the oil to bypass the separation chamber. Oil that bypasses an OWS can cause a
potential pollution problem or can result in a local pretreatment permit violation.
OWSs should discharge into a sanitary sewer system. Local municipalities may require
notification and operational limits for connected OWSs. The facility can contact the local
municipal pre-treatment coordinator for additional information. If the facility utilizes a septic
system, the OWS should not discharge to the same septic tank to which domestic sewerage
discharges. Oil that bypasses the OWS can cause a septic tank to malfunction.
There are additional NPDES permit requirements, including analytical monitoring requirements,
for any OWS that discharges to the stormwater drainage system.
Abandoned OWSs should be plugged and abandoned.
3.10 Vegetation Practices
Preserving existing vegetation or revegetating disturbed soil as soon as possible after
construction is the most effective way to control erosion.
Four ways vegetation reduces erosion:
• 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
• 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 buffers around the site 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 revegetation because they grow quickly and provide erosion
protection within days. Straw or mulch may be used during noh-growing seasons to prevent
erosion. Keep existing shrubs and trees because their established root systems help prevent
erosion.
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.
North Carolina Army National Guard 17
Stomwater Pollution Prevention Plan,

3.11 Sediment and Erosion Control
Sites 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 by 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. ,ot%
Areas that are erosion -prone or where construction activity is occurring at the facility will be
inspected regularly. Sedimentation and erosion control devices will be installed and maintained.
Areas with such heavy activity that plants cannot grow, soil 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.
Several ways to limit and control sediment and erosion:
• 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
• 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.
3.12 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 l
North Carolina Arrm National Gua/d 18
Stormwater Pollution Provention Plan

pollutants to stormwater discharges from industrial activity must be considered when determining
reasonable and appropriate measures. Appropriate measures may include:
• Vegetated buffer zones (grassed 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
• 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 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 minimize the pollutants leaving the site. The ;t4PDES Permit does not
specify any one stormwater management practice since these practices must be selected on a
case -by -case basis depending on the activities and flow characteristics at the facility.

4.0 TRAINING, INSPECTIONS, AND RECORD KEEPING
4.1 Training
Facility personnel will be trained in Stormwater Pollution Prevention procedures and NPDES
permit requirements annually. Such training will be documented. New personnel will receive
training promptly upon assignment. The FEC will develop a schedule and coordinate training for
all SWPPT members in the elements of the SWPPP. The SWPPT members will coordinate
training on the proper completion of BMPs for all personnel under their command.
Personnel will be trained in:
General good housekeeping - Storage of materials, preventative maintenance of
equipment; checking for leaks and spills; and, preventing exposure of POL, hazardous
substances, and waste materials to stormwater.
Spill prevention and response in accordance with existing SPCC Plan and/or HMWMP
procedures - Securing drums and containers; handling materials; identifying toxic and
hazardous substances stored, handled, and produced on -site, safe fuel handling
procedures and spill notification procedures, and appropriate contacts.
Record keeping and Inspections - Conducting inspections and producing and maintaining
records, including spill reports, in accordance with SWPPP guidelines.
4.2 Inspections
Facility Inspections pertaining to industrial activity must be conducted according to the
requirements of your facility's permit. Your facility's stormwater permit requires written
documentation of scheduled inspections and for those records to be retained for 5 years.
4.2.1 Visual Observations of Stormwater Outfalls
Visual observations will be made at each. designated industrial stormwater discharge outfall point
(see SDOs labeled "visual observation' on Table 2 and Map 2). Visual observations are made in
order to evaluate the effectiveness of the SWPPP and assess new sources of stormwater
pollution. The NPDES Permit requires that visual observations will be performed twice per year,
once in the spring (April — June) and once in the fall (September — November). No analytical
monitoring is required of the visual grab sample.
If analytical monitoring is required at the facility, then the first visual observation event during the
coverage of the NPDES Permit must coincide with the initial analytical monitoring event
(regardless of the season).
Table 4 shows the parameters that will be observed during the visual observations.

` Visual observations shall be performed at each stormwater discharge outfall (SDO) or at
the next accessible point upstream.
Form 3, Visual Observation Report, included in Section 5 will be used to document the visual
observations. Directions for completing the report are provided below:
Adverse weather conditions that may prohibit visual observations of stomiwater discharge outfalls
include weather conditions that create dangerous conditions for personnel (e.g., local Flooding,
high winds, hurricanes, tornadoes, electrical storms). When conducting visual monitoring of
outfalls, SW PPT personnel are required to follow standard safety practices.
1. This report is to be completed once in the spring and once in the fall for each industrial
stormwater discharge outfall located at the facility. Use one form for each outfall. The
visual observations must occur during a rainfall event.
2. Refer to the SW PPP Site Map (Map 2) for outfall location and identification.
3. Shortly after rainfall begins, discharge will begin flowing from the outfall. After discharge
has been Flowing approximately 5 to 30 minutes, collect about one half liter of discharge
water into a clean glass container and record the observations. Observations can apply
either to the collected water, or to the flow from the outfall.
4. Examples of color descriptions include light red, or dark brown.
5. Examples of odor descriptions include strong smell of rotten eggs, or faint smell of
gasoline.
6. Clarity is a measure of the cloudiness of the water. Examples of clarity descriptions include
clear, murky, very cloudy, or opaque.
7. Floating solids are things like trash, pieces of plastic, shavings, or other items that float and
can cause receiving stream degradation. Grass clippings should also be reported on the
form; the dumping of yard debris into the storm drainage system is not allowed.
8. Suspended solids are typically small particles such as grit or sediment that are suspended
within the water column.
9. Foam can be caused by detergents and other chemicals, as well as from a natural ,
occurrence due to the area's soil mineralogy. Circle "yes" if foam is present. ._
North Carolina Army National Guard 22
Slo,mwater Pollution Prevention Plan

10. Any amount of oil sheen is technically a violation of the Clean Water Act (40 CFR 110.3).
Realistically, incidental oil sheen from parking lot runoff cannot be totally eliminated. If oil
sheen is visible, circle "yes."
11. Other possible indicators of stormwater pollution include distressed vegetation at the outfall
outlet, deformed amphibians, a dry weather flow, illicit connections, or improper disposals.
12. The more detail provided the better. This form will be used to assess the effectiveness of
the SWPPP during annual evaluations.
13. The inspector will sign the form when completed.
14. Insert the completed form into the facility SWPPP document. The NPDES Permit does not
require a copy of this form be sent to NCDWQ, but the form must be kept on -site with the
SWPPP document. Also e-mail, fax or mail a copy of Form 3 (Form 3 is the same form as
the old SWPPP 'BMP Checklist #6 ") to the Environmental Compliance Manager in the
Environmental Office.
When conducting wet weather visual observations at outfalls that receive off -site runoff, the
effects of this off -site runoff can be minimized by conducting the wet weather visual observation
within the first ten minutes of discharge from the on -site ouffall.
If stormwater discharges are determined to be polluted, the source of the pollutants will be located
and minimized to the extent practical. Refer to Section 3 Best Management Practices for
descriptions of applicable measures that can be implemented to reduce pollutants.

4.2.2 Facility Preventative Maintenance Inspections
The NPDES Permit requires facilities to conduct semi-annually preventative maintenance
inspections at designated storm water management devices (e.g., catch basins, oil/water
separators, etc.), and designated facility equipment and systems that upon failure, could result
in discharges of pollutants to the storm drainage system. These inspections should coincide
with the semi-annual (spring and fall) visual observations of each stormwater discharge ouffall.
Form 4, Facility Preventative Maintenance Inspection, included in Section 5 will be used to
document the inspections and any subsequent maintenance activities. Completed copies of the
form will be inserted into the SWPPP document and kept on -site for at least five (5) years.

4.2.3 Release of Rainwater from Secondary Containment Structures
Secondary containment devices for bulk storage of liquid materials connected directly to
stormwater conveyance systems will be controlled by manually activated valves or other similar
devices. The drain valves for the containment structures will be closed at all times except when
making a controlled release. The drain valves will be secured with a locking mechanism. Any
stormwater that accumulates in the containment area will be visually observed for color, foam,
outfall staining, visible sheens, and dry weather Flow prior to release of the accumulated
stormwater. Alter each significant precipitation event, facility operators will inspect the rainfall or

snowfall that has accumulated in the secondary containment areas. If there is no evidence of oil
or chemical contamination, the valves can then be opened to release the clean stormwater to the
drainage system. If oil or chemicals appear to be present, the contaminants will be removed and
disposed of in accordance with local, state, and federal regulations. It may be necessary to
remove and dispose of all the accumulated rainwater as a contaminated waste.
The drain valve openings and rainwater releases are required to be documented. Form 5,
Release of Rainwater From Secondary Containment Structure, included in Section 5 will be
used to document each rainwater release. Completed copies of the form will be inserted into the
SWPPP document and kept on -site for at least five (5) years. After releasing accumulated
rainwater, the drain valve is closed and locked.
Accumulated sludge in non -exposed secondary containment structures will be characterized,
either by analytical methods or generator knowledge, and disposed accordingly.
An accidental release from a secondary containment structure, including diked or bermed
areas, should be treated like an accidental release or spill from any bulk storage tank.
Appropriate spill response and reporting procedures will be followed to document the release.

4.2.4 Hazardous Waste and Hazardous Material Storage Areas
All NCARNG facilities must conduct internal inspections of Hazardous Waste Accumulation
Consolidation Sites, Satellite Accumulation Points and Hazardous Material Storage Areas and to
document inspection results. Hazardous waste and hazardous materials storage areas are
currently inspected according to the procedures listed in the NCARNG HMW MP.
4.2.5 Non-Stormwater Discharges
The only non-stormwater discharges which shall be allowed in the stormwater conveyance system
under the NPDES Permit are:
r All other discharges that are authorized by a non-stormwater NPDES permit
r Uncontaminated groundwater, foundation drains, air-conditioning condensate without
added chemicals, springs, discharges of uncontaminated potableeater, watedine and fire
hydrant flushings, water from footing drains, flows from riparian habitats and wetlands
r Discharges resulting from fire -fighting or fire -fighting training
Note that discharges of washwater from steam cleaning and other equipment cleaning operations
are not allowed.
The holders of NPDES permits for discharges of stormwater associated with industrial activity are
required to inspect ouffalls to show that only stormwater is discharged from listed outfalls. An
investigation to identify potential non-stormwater discharges was performed as part of the
development of this SW PPP (see Table 5). The NCARNG shall certify that the investigation was
performed for areas where industrial activity occurs (Form 1). The FEC must ensure that the
certification is signed and dated.
The following methods are typically employed in these types of investigations to determine
whether or not non-stormwater discharges are present:
• Visual observation of the outfalls
• Interview with facility personnel
• Review of as -built infrastructure drawings
• Testing of floor drains and drainage system using smoke, dye, or video
• Analytical monitoring
When non-stormwater discharges or unauthorized sewer connections are discovered, a plan to
eliminate the discharge shall be developed and carried out. Non-structural corrective actions
should be performed immediately and will require an amendment to the SWPPP to reflect the
completion of the BMP. Structural modifications should be made as soon as possible, but in no
case later than three years after the effective date of the NPDES stormwater discharge permit.

4.2.6 Analytical Monitoring
The NPDES Permit requires that stormwater discharge analytical monitoring be performed at
designated outfall points for facilities conducting vehicle maintenance activities and utilizing more
than 55 gallons new motor oil per month when averaged over the year. Vehicle maintenance
facilities not utilizing more than 55 gallons of new motor oil per month are not required to conduct
analytical monitoring.
Oil/water separators (OWSs) that discharge to the stormwater drainage system are subject to
analytical monitoring under this NPDES Permit. Stormwater discharges from any selected
OWS must be collected and analyzed once per year for the duration of NPDES Permit
coverage; cut-off limits do not apply. OWSs that discharge to a sanitary sewer system are not
subject to monitoring under this NPDES Permit.
No analytical monitoring is required at this facility.
4.3 Record keeping and Reporting
This SWPPP will be maintained on -site at the office of the FEC. The'§WPPP will be reviewed
annually and updated by the SW PPT as needed. The FEC will maintain inspection records and a
certification that the facilities are in compliance with the SWPPP (indicating accomplishment of
BMPs) or identify any incident(s) of non-compliance. The FEC shall amend the Plan whenever
there is a change in design, construction, operation, or maintenance, which has a significant effect
on the potential for the discharge of pollutants to surface waters. The facility is not required to
submit the SWPPP for review unless requested to do so by USEPA or the NCDWQ. If the
SWPPP is reviewed by the USEPA or NCDWQ, the facility may be required to amend the
SWPPP.
® Reports and changes to the SWPPP will be retained on -site for at least five (5) years after
expiration of the NPDES stormwater discharge permit.
® The facility will retain records of all stormwater monitoring information required by the
NPDES Permit for a period of five (5) years from the date of the sample, measurement,
report or application.
For inspections of secondary containment discharges, records will document the individual
making the observation, the description of the accumulated rainwater and the date and time of the
release. Records will be kept on -site for a period of five (5) years.
Twenty-four Hour Reporting
® The facility shall report to the Environmental Office any non-compliance, which may
endanger health or the environment. Any information shall be provided verbally within
24 hours from the time the reporting individual became aware of non-compliance. A
written report shall also be provided within five days of the time the reporting individual
becomes aware of non-compliance.
® Written reports shall contain a description of the non-compliance event, its causes, the
period of non-compliance, including exact dates and times, and if the non-compliance
North Carolina Army National Guard 28
Stormwater Pollution Prevention Plan

event has not been corrected, the anticipated time non-compliance is expected to
continue. Steps taken or planned to reduce, eliminate, and prevent reoccurrence of non-
compliance shall also be included in the written report.
P The facility shall report all instances of non-compliance not reported under the 24-hour
reporting requirement to the Environmental Office at the time monitoring reports are
submitted.
