MIL-HDBK-1022A
motor-operated with the concurrence of Service Headquarters.
Tank trucks can be as large as 10,000 gallons (38 000 L) in
capacity and tank cars as large as 40,000 gallons (151 000 L).
If a canopy, which is designed to preclude rain from the
contained area, is installed, reduce the sizing for rainfall,
accounting only for wind-blown rain. Consider combining the
containment with other containments or treatment facilities
onsite. However, take the level of contamination in each
containment area into consideration. Do not use asphalt
within a containment area.
e) For off-loading tank trucks, arrange the flow of
traffic to permit continuous forward movement of trucks at all
times. Commercial tank trucks off-load on the passenger side.
f) To determine the number of connections needed for
off-loading tank cars, consult with Service Headquarters and
consider tank car shipping schedules, conveyance turn-around
times, local rail switching capabilities, and quantity of fuel
needed for one day's fuel supply.
g) Provide an electrical design that meets the
minimum requirements of NFPA 70, NFPA 77, and NFPA 780. Treat
combustible liquids under pressure as a flammable liquid.
h) When authorized by Service Headquarters, protect
the off-loading rack by a weather cover designed for severe
weather conditions. The weather cover must be justified by
severe environmental conditions impacting operations (low
temperature and snow) or economically justified by reducing
stormwater runoff and eliminating the need for stormwater
collection and treatment. If the protective structure is
included in the design, ensure that the underside of the roof
is high enough to provide operator head room when walking on
top of the truck or for access to rail car domes. Ensure
structural design is in accordance with MIL-HDBK-1002 series
and the Army Corps of Engineers AEI or MIL-HDBK-1002/3.
i) Provide for egress and entrance of emergency
response vehicles.
j) Provide in-bound filtrations.
This is normally a
horizontal filter/separator.
