SPILL PREVENTION
Spiii prevention is required for every
underground storage tank (UST) that is filled
with more than 25 gallons of product at one
time. Spill prevention devices attached to
your UST (for example a spill bucket) can
help prevent releases into the environment.
Spill bucket
Repeated small releases can cause big
environmental problems. Spill buckets can
be a common source of spills. Improper
maintenance of your spill bucket may
contribute to significant soil and groundwater
contamination.
What can you do to prevent
spills from spill buckets?
Remove debris/liquid in spill buckets
Spill buckets are designed to temporarily
contain small product spills released
during delivery and are not for long-term
storage of product. Accumulated
debris or liquid reduces containment
capacity and ability to prevent spills.
Keep your spill buckets
clean and dry. Empty
spill buckets immediately
and properly dispose of
the contents.

Replace damaged gaskets and seals
*** Damaged seals and gaskets can result in
non-tight spill buckets. This can allow a
release into the environment.
Periodically inspect all
seals-including around
the fill riser-for any
cracks, damage, or
holes. Replace or repair,
as needed.

Most spill containment
is not designed to last
as long as an UST.
Periodically inspect for
damage, corrosion,
and deformation.
Perform an integrity
test and, if necessary,
repair or replace to
make sure it works
properly.
