(4) Submersible pump containment sumps to contain any fuel leaking from the
pump or piping connections. Containment sumps shall have electronic leak
detectors to report the presence of leaking fuel.
(5) Cathodic protection system consisting of tank coating and internal tank
anodes.
(6) Pressure/vacuum vent valves to prevent tanks from over pressurizing
(positive or negative) during filling procedures or due to thermal
contraction/expansion of product.
(7) Submersible pump leak detector to shut down pump if detector suspects a
leak in the primary piping system.
(8) Monitor walls in the tank area to monitor for contaminants in the soil and/or
groundwater.
(9) Emergency stop switch at cashier's counter to shut down entire fueling
operation in the event of a spill or fire.
Fuel is delivered to the underground tanks by tanker. Each truck holds
approximately 8,000 - 10,000 gallons. The most likely route the transport truck would travel
would be along E. Harmony Avenue to the site from the east. The truck would leave the
site via E. Harmony.
Some of the most realistic scenarios involving use of gasoline at this facility include:
(1) A spill at the dispenser due to consumer lack of attention or mechanical
failure. This spill would be minimal based on a two minute response and a
flow rate of ten gallons per minute. Twenty gallons of gasoline probably
would not travel off site and could be controlled by spreading an absorbing
material and evaporation. A manual shut-off gate is also provided in the 2
foot chase drain to prevent any spillage running into the storm system.
(2) A larger surface spill originating at the underground storage tank area during
a product delivery. Fuel is "dropped" into the underground storage tank by
gravity fill. The most likely scenario would be the delivery hose becoming
disengaged from the truck or tank connection. Since the truck driver is
required by law to stay within sight of and within control of the delivery
operation, a spill should not exceed a quantity of approximately 250 gallons.
In the event of this type of spill, the fuel would travel to the southwest portion
of the site. The fuel would stay within paved areas contained by site curbing.
The outlet for the storm water from this area releases into the large roadside
ditch along Harmony. It would be possible for the driver to manually block
the 2 foot chase drain with a manual shut off gate and contain the spill within
Proiect Information
The proposed development is a Safeway Fuel Facility with gasoline fuel sales and
a convenience store. It is located near the northwest corner of East Harmony Road and
McMurry Avenue in the City of Fort Collins.
The adjacent property to the east, west and north is currently a developed retail
center anchored by a Safeway grocery store. These properties are zoned HC-Harmony
Corridor, Neighborhood Service Center. The properties to the to the south across East
Harmony Road are also zoned HC and are within the Oakridge Business Park and
currently undeveloped.
The hazardous material utilized by this operation is unleaded gasoline. There will
be two, 20,000 gallon underground doublewalled steel/frp composite storage tanks. One
of the tanks is a double compartment to contain 10,000 gallons of premium unleaded and
10,000 gallons of super unleaded gasoline. The other 20,000 gallon tank will contain
regular unleaded gasoline. The storage and distribution system complies with the State
of Colorado requirements regulating service stations. The distribution system contains the
following safety features:
(1) Multiple product dispensers with:
(a) Automatic nozzles to prevent customer overfill and spillage.
(b) Hose break -away connections that separate and seal the hose
opening when customers drive off with the nozzle still in the vehicle.
(c) Emergency shut-off valves under the dispenser that shut off gasoline
flow into the dispenser when either:
(1) The dispenser sustains an impact and the emergency valve
shears away, or
(2) A fire melts a fusible link connection on the valve.
(2) Dispenser containment sumps to collect any fuel spillage under the dispenser
and prevent soil contamination. Dispenser sumps shall have electronic leak
detectors to report the presence of spilled fuel.
(3) Doublewall fiberglass piping to contain fuel in the event of a primary piping
failure.
