Dangers That May Occur If Tank Decommissioning Is Not Done On Time:

Underground storage tanks (UST) possess toxic materials such as gasoline and waste oil, which holds harmful substances that may cause cancer like diseases and can be dangerous for developing children. Also the hazardous chemicals can easily move through soil and pollute groundwater, which is the source of drinking water for the majority. Hence, Decommissioning Of A Tank is a priority and necessity in saving the environment from serious destruction.

What Is Temporary Decommissioning Of Tank And How Is It Different From Permanent Decommissioning?

Any leakage from these remaining products can cause life risking dangers for living organisms and pollute the environment severely. If you cannot monitor the remains, you must immediately do away with the tank which is known as Permanent Tank Decommissioning.

Steps Needed To Be Followed While Decommissioning of Tank:

Next step is to remove any residual items from the bottom of the tanks or pipes. Furthermore, the harmful and explosive gases are also needed to be discarded from the tanks so that they remain risk-free when eliminated from the ground.

Next, it becomes important to clear the pipes, containers and panels.

It is even better to do away with the tanks and all the related pipe works which will be no longer in use.

After the bottoming is done, you must make sure that it is free from any explosive vapours, by filling it with inert gases or water. In case, where water is filled, you need to dispose the water later. The entire process must be done within the supervision of the local undertaker and that too lawfully. Monitoring the removal of the pipes must also be done with extra care and cautiousness. Since the whole process is dangerous and any kind of carelessness may cause serious environmental damages, it is very necessary to monitor the entire work thoroughly and skillfully.

Hence, it is always preferable to bring a permanent closure to them as quickly as possible. A tank can be left on the site permanently only when the environment agency is sure that there is no risk to the surroundings, soil or underground water. When it is planned to leave the tanks or pipes in place once they are totally safe, it is necessary to fill them with sand or cement, hydrophobic foam or foamed concrete. This is called ‘inerting’. Points which are important must be jotted down in Decommissioning Of A Tank Temporarily such as date of decommissioning, the method of commissioning, the product it contained, its capacity etc.

Thus, Temporary Decommissioning Of A Tank is a risky work and needs proper guidance and monitoring. If it is not possible to monitor the tanks, it is better to go for permanent decommissioning of the tank in order to keep the nature and environment risk-free and safe.
