Facilities Operation and Maintenance Plan
Town of Gibsonville
INTRODUCTION
This Operation and Maintenance (O&M) Plan has been developed with the goal of
preventing or reducing pollutant runoff from Town of Gibsonville owned facilities and
operations. It has been developed as required under Section G of the State of North
Carolina's Pollutant Discharge Elimination System Stormwater Discharge Permit No.
NCS000405, issued to the Town effective July 1, 2005.
This O&M Plan describes the Town owned facilities and their operations, identifies
potential sources of storm water pollution at the facilities, recommends appropriate best
management practices (BMPs) or pollution control measures to reduce the potential of
discharge of pollutants in storm water runoff, and provides for periodic review of this
O&M Plan.
2. GOALS AND OBJECTIVES
The primary goal of the storm water permit program is to improve the quality of surface
waters by reducing the amount of pollutants potentially contained in the storm water
runoff from Town owned facilities. Specifically, this Plan will be in place to reduce or
eliminate the exposure of oil and grease, pesticides, herbicides, fertilizers, sediment,
and other chemicals used by the Town, to stormwater. With this understanding, the
Town has developed Best Management Practices (BMPs) to reduce or eliminate the
stormwater exposure of pollutants from Town activities to the maximum extent practical.
3. RESPONSIBLE PARTIES
The Operation and Maintenance Plan Coordinator for Town facilities is designated as
the Public Works Director, currently Mr. Rob Elliot.
Resaonsibilities:
A. Maintains materials, inventories, and handling and storage practices.
B. Inspection and maintenance of best management practices.
C. Plans and schedules education -training programs
D. Annual site inspections and assessments.
E. Coordinates clean up of spills and releases.

Facilities Operation and Maintenance Plan
Town of Gibsonville
5.1 Town Hall & Police Department
Both Town Hall and the Police Department are housed within the same building and
share a common parking lot. All of the operations performed at these facilities are
administrative in nature and are contained within the building. Other than Town
vehicles, no material handling or storage practices occur outside of the building. The
parking lots and drainage systems appeared to be in good condition. The potential for
stormwater pollution from this site was determined to be minimal.
5.2 Library
Similar to Town Hall, the operations at the Library are administrative in nature. No
material storage or handling practices occur outside of the building. The parking lots
and drainage systems appeared to be in good condition. The potential for stormwater
pollution from this site was determined to be minimal.
5.3 Fire Department
This facility houses administrative offices, the Town's fire apparatus and equipment, and
firefighter accommodations. This facility is staffed 24 hours a day 7 days a week. Other
than fueling, no equipment maintenance or repair is performed at this facility.
Floor drains are located throughout the facility. These drains are open and drain into the
sanitary sewer. A hazardous materials cabinet is located in the corner of one of the
bays. The cabinet was in good condition with the doors closed and there was no sign of
materials leaking from the cabinet. Two fuel tanks, one gas and one diesel, are located
behind the Fire Station. The fuel tanks are double walled but are uncovered and have
no secondary containment system or spill kits. The main facility poses a minimal
potential for stormwater pollution but the fueling area gives this site a high potential for
stormwater pollution.
5.4 Community Center
The Town converted the old Public Works Facility into the Recreation Department in
2017. The old facility consists of a main shop building, two open garages, a fueling
area, a waste oil storage tank, a container dumpster, and material / equipment stockpile
areas. The community center is one building with a parking lot that has good drainage.
Regular cleaning products are stored in a closet with no floor drain. Behind the facility
there is a Stormwater dry detention basin. The Basin needs to be regraded and resown;
however, there is not a stormwater pollution hazard. Adjacent to the community center
is the Tenth Street Water tower, Murrell Recreational Park, and a railroad system on the
far side.
Due to the condition and nature of the site, there is minimal potential for stormwater
pollution.

5.5 Public Works Facilities
The Public Works Facility consists of a main building with offices and restrooms, two
main shops, a parking lot, an outdoor fueling station with three gas or diesel pumps
along with secondary containment structures, a large shed area that is open on all
sides, a new salt storage area, two smaller enclosed sheds and a material stockpile
area. The building consists of offices in the front and a shop area in the rear. All
equipment and materials that have the potential to generate stormwater pollution are
contained within the shop area of the building
Main Shops -The floor drains in the main shops are run through an oil water separator
and then to the sanitary sewer system. They had eye wash stations, and spill clean-up
material readily available, would recommend boldly labeling the spill material. Used oil
container was kept inside the shop, with no secondary containment unit, it was kept
near one of the bay entrances, and would recommend moving away from the entrance
to reduce the risk of rainwater washing oil outside of the bay area. All chemicals were
stored inside and on shelves with the lids on. Small bays were built into the side of the
second main shop, these small bays contain miscellaneous chemicals and paints, also
miscellaneous maintenance parts. The chemical bay has a screen door and is able to
be locked.
Smaller Sheds- completely enclosed, filled with quickrete on a pallet, miscellaneous
landscape maintenance material, road signs, cones, Christmas decorations, and minor
equipment like a lawn mower. Make sure all miscellaneous buckets are cleaned out and
there is no left over chemical/fertilizer in them, or completely close them and store them
properly.
Material Stockpile Area- Miscellaneous bricks, blocks and parts are located here, no
obvious threats to stormwater pollution were observed here.
Cont.-Different types of gravel are located on the north western side of the property,
they are blocked in so they don't spread out and wash away.
Salt Storage Building- New building in good condition, salt storage area is completely
enclosed on three sides, and covered, there are plans to add a large sliding door to this
facility to further ensure protection of water quality. Broom and shovel also available at
this site. Storage area attached to the salt building- a few 55-gallon barrels stacked up,
one obvious leak here.
One large uncovered dumpster outside, unused trashcans are kept outside.
Large Shed- Large equipment kept underneath the large shelter including dump trucks,
spreaders, hay, trucks, a tractor, and other miscellaneous equipment. No major signs of
leaking from any equipment.

Outside Structures —There is a dry detention pond with gravel to assist with stormwater
runoff control. There is a sediment basin that has not had the proper upkeep. It would
be advised to properly maintain the sediment to improve erosion control efficiency.
5.6 Senior Center
The Senior Center is located in the rear of the Steele St. Apartments. This facility
consists of a main building, storage building, walking track, and parking lot. The parking
lot and stormwater inlets are in good condition. A large amount of trash is piled behind
the storage building. Because of the unknown contents of this trash there is a potential
for solution.
5.7 Parks & Recreation Facilities
The Town owns two parks, Moricle Park and Murrell Park. The Town also manages two
parks, Northeast Park and Southwest Park, both owned by Guilford County. Other than
landscaping and limited storage of materials little activity goes on at the parks that
would have the potential for stormwater pollution.
5.8 Water and Wastewater Facilities
The Town owns twelve water and wastewater facilities. A few of these facilities have
been abandoned and are no longer in service. There is no material exposure at any of
the facilities and other than the potential of a stream impact due to a pump station
failure, there is minimal potential for stormwater pollution at any of these facilities.
6. FACILITY SPECIFIC BEST MANAGEMENT PRACTICES
Stormwater management controls, or best management practices (BMPs), will be
implemented over the course of the following year to reduce the potential of pollutants
entering the stormwater discharged from Town owned facilities. The following lists the
specific BMPs the Town will employ to minimize, to the maximum extent practical, the
possibility of pollutant exposure to stormwater for the areas identified above.
6.1 Fire Department
• Inspect vehicles periodically for leaks and install catch pans under vehicles
when leaks are found.
Cover and install a secondary containment system for the fuel tanks and
fueling area.
• Install spill kits for the fueling area.
6.2 Community Center
• Regrade the dry detention pond

Town of Gibsonville
6.3 New Public Works Facility
• Require all vehicle and equipment washing to be performed at the old
public works facility in the main shop building where wash water will be
routed through the oil/water separator.
• Install silt fence near the stream at the bottom of the hill at the material
stockpile area to prevent any erosion from entering the stream.
• Perform proper maintenance and upkeep on the sediment basin
6.4 Senior Center
• Remove and properly dispose of trash behind storage building.
7. GENERAL BEST MANAGEMENT PRACTICES
The following general BMPs will be implemented to minimize the potential for
stormwater contamination from everyday operations at Town owned facilities.
7.1 Vehicle and equipment storage
Remove and dispose of all unused vehicles and equipment, if possible. If
vehicles and equipment are to be stored outside for longer than a month, drain
fluids. When practical, cover equipment and divert storm water around the
equipment.
7.2 Street Sweeping
Increase Town -wide street sweeping to cover all curb and gutter within the Town
every 2 months. In addition, sweep all the paved areas around the main building
and fueling areas at the public works facility once a week. Dirt and debris
collected during the sweeping will be disposed of at the landfill.
7.3 Grounds Maintenance
• Use care when spreading fertilizer to prevent contact with the stormwater
system.
• Minimize use of pesticides/herbicides. Use weed eater instead of
herbicides when possible.
7.4 Waste Disposal
• All wastes (including solid waste, waste oil, empty drums) generated by the
Town will be properly disposed of via outside contractors.
• Wastes will be stored in containers sealed from precipitation or stored
under cover or inside buildings.

Town of Gibsonville
7.5 Outdoor Material Storage
• Remove and dispose of all unnecessary materials, equipment, and debris.
• Store materials on pallets or elevated platform to prevent corrosion.
• Cover materials with tarps to minimize exposure.
• All empty containers stored outside will be tightly sealed and the outside
free of contamination.
7.6 Good Housekeeping Practices
• Work, storage, and vehicle parking areas are to be kept clean and orderly.
• Routine maintenance and cleaning of areas that are exposed (or have the
potential to be exposed) to stormwater runoff will be performed to minimize
stormwater pollution.
• Sweep or dry mop when cleaning outdoor areas. Avoid washing or hosing
down the area.
• Clean up spills promptly.
8. ANNUAL INSPECTION PROGRAM
Annual inspections of all Town owned facilities will be conducted and this plan
reviewed. The effectiveness of the BMP's implemented during the previous year will
also be evaluated. Based on the results of the inspections and BMP evaluation, this
Operation and Maintenance Plan will be updated and modified to ensure the risk of
stormwater pollution from Town operations is minimized.
9. EMPLOYEE TRAINING
An employee training program will be developed and implemented to educate public
works employees about the requirements of this O&M Plan. This education program
will include background on components of the O&M Plan and hands-on training in spill
prevention and response, good housekeeping, proper material handling, disposal and
control of waste, washing, and inspection procedures.
All new employees will be trained within one week of their start date. Additionally, all
employees will be required to participate in an annual refresher training course. The
training program will be reviewed annually by the Plan Coordinator to determine its
effectiveness and to make any necessary changes to the program.
