Fire Protection Description
Means of Storage
11,000-gallon tank (8.25 ft. diameter x 33.5 ft. long). Diesel will be used to fuel
the diesel fire water pump and the diesel generators. This tank is not designed
as a supply source for fueling vehicles.
3,000-gallon liquid nitrogen storage tank (8 ft. diameter x 17.67 ft. tall). The
tank will be provided by the nitrogen supplier. Nitrogen gas will be delivered
(by pipe) to the retort.
1,500-gallon liquid oxygen storage tank (6.5 ft. diameter x 15.75 ft. tall). The
tank will be provided by the oxygen supplier. Oxygen gas will be delivered (by
pipe) to the retorts.
5,000-gallon sanitary wastewater collection tank (10 ft. long x10 ft. wide x 9 ft.
tall)
The following is the basis for the proposed TSF’s Fire Protection System:
In the event of a fire, the Fire Water Tank (1542-TK-020) can provide up to two
hours of firefighting capabilities at 2,000 gallons per minute (GPM) with no
recirculation (see “Fire Water Supply and Distribution” below for details of Fire
Water Tank design).
Within these two hours the local fire department/emergency response team will be
called to the site. At such time, tanker trucks may provide additional fire water
resources.
All fire water discharged within the plant spaces of the proposed TSF may become
contaminated; therefore, it will be collected.
In the unlikely event of an extreme fire within the plant spaces of the proposed TSF
where the building water containment volume limit is reached, the following means are
available to continue combating a fire, in order of preference, illustrated in Figure 1.5-3:
