Owners and operators of
   regulated underground
storage tanks (USTs) on tribal
   lands must comply with
  federal UST regulations.

  brochure highlights best
   management practices
      for spill buckets.

Spill 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

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.
Liquid in spill bucket
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-tor any

                                                                            as needed.

Repair or replace damaged spill buckets
^  Damaged, cracked, or corroded spill
    buckets are not liquid-tight and will not
    contain the spilled product.
Deformed spill bucket wall
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
                                                    Damaged spill bucket
A damaged, missing, or
poorly fitting spill bucket
lid may allow water and
debris to collect in the
spill bucket and enter
into the tank.
                                                                                  Broken spill bucket lid
