Anyone involved with the decommissioning of USTs must become very familiar with and knowledgeable about
those hazards, as well as the safety and health practices and procedures that must be followed in order to
minimize and eliminate the potential for serious injury to people and/or damage to the environment.
Tank decommissioning includes the activities required to
take a tank temporarily out-of-service, or to permanently
close, remove, and dispose of the tank.
Hazards involving fire, explosion, chemical burns, inhalation
of vapors during decommissioning of UST systems can
cause for example:
severe damage to internal organs
permanent or chronic sicknessand disease
asphyxiation and death
crushingand suffocation due to cave-ins
severe injury from falls from height
Extreme caution should be exercised at all times during the decommissioning process.
There are specific requirements that the owner or operator must follow when temporarily or permanently
taking a tank out of service. These activities fall under the responsibility of the Class A operator, and are
discussed below for situations where temporary out-of-service or permanent closure may be necessary.
