2.13.5.5 Oil/Water Separators. Pass water from stormwater
drainage systems through a gravity type oil water separator.
Check with local environmental authorities, select either a
conventional rectangular API type or one with inclined
parallel plates. Where possible, design the separator as a
rectangular vessel with a fully open top with lid for ease of
inspection and cleaning.
a) Design and construct the separator in accordance
with the following:
(1) NAVFAC DM 2.04, MIL-HDBK-1002/1 and

hour duration storm event.
(2)
Type of fuel.
(3)
Specific gravity and viscosity of fuel.
(4)
Specific ambient and product temperature
ranges.
(5)
Product storage capacity required.
