Q. What is an "Abandoned" Underground
Storage Tank?
A. Many underground storage tanks are no
longer being used, rendered obsolete by piped-in
natural gas or electric baseboard heat. An
underground storage tank that is no longer
in use is considered "abandoned".
Q. What Should Be Done With An Abandoned
Underground Storage Tank?
A. Department of Ecology and many Local Fire
Departments recommend permanent closure for
abandoned underground storage tanks. The
process of permanently closing a tank is
referred to as "decommissioning"".
A tank may either be decommissioned by capping,
filling it with an inert material such as
slurry or foam or by removing it from the
ground. Decommissioning also involves removing
heating oil and sludge from the tank.
Many underground storage tanks have been
abandoned with oil still in them. You should
consider arranging to have any remaining
oil removed from the abandoned tank if you
do not immediately decommission it. This
will help prevent possible contamination
of soil and ground water.
Q. What is your response time?
A. Immediate to 10 days from signed contract
. Generally we can respond within 10days
of a signed contract but some emergency situations
we can obtain permits and be onsite immediately.
