proceed into the retention pond, the fuel will remain there because
there is no outlet or connection from the pond to the City's storm water
system. The contained fuel could then be properly cleaned up and
disposed of under the supervision of the Poudre Fire Authority.

(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 wells in the tank area to monitor for contaminants in the soil
and/or groundwater.
(9) Emergency stop switches at cashier's counter and fuel dispensers to
shut down entire fueling operation in the event of a spill or fire.
Fuel is delivered to the underground tanks by tanker truck. Each truck
holds approximately 8,000—10,000 gallons. The most likely route the transport
truck would travel would be along Taft Hill Road to the site. The truck would
leave the site via Elizabeth Avenue.
Some of the most realistic scenarios involving use of gasoline and diesel
fuel 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
fuel would not travel off site and could be controlled by spreading an
absorbing material and evaporation.
(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 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 northeast portion of the site. The fuel would likely
stay within paved areas contained by site curbing. The outlet for the
storm water from this area releases through two (2) curb openings into
the onsite retention pond in the northeast corner of the site. It would
be possible for the driver to manually block these curb openings and
Project Information
The proposed development is a King Soopers Fuel Facility. It is located at
the southwest corner of Taft Hill Road and Elizabeth Avenue in the City of Fort
Collins.
The property is currently developed as a multiple -bay vehicle service
center, with a car wash with fuel sales.
The hazardous materials utilized by this operation are unleaded, gasoline
and diesel fuel. There will be two, 20,000 gallon underground doublewalled
steel/frp composit storage takes. One of the tanks is a double compartment to
contain 10,000 gallons of premium unleaded gasoline and 10,000 gallons of
diesel fuel. 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
fuel 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 piping to contain fuel in the event of a primary piping
failure.
