Key Things To Know About Storage Tanks Underground

Companies and residents use underground tanks for a variety of purposes. However, the tank needs a proper lining to prevent leaking of water, chemicals or gas into the ground. Those chemicals affect not only the surrounding ground but can leak into water supplies affecting neighboring communities.

Liners

Tank liners help keep the tank from corrosion. Tank lining companies offer custom linings for chemicals, oil and water tanks. Without the liner, the tank can leak leaving the owner of the tank responsible for the cost and hassle of cleaning up the spill. Ensuring the tank is lined properly can prevent a leak and the costly clean up associated with it. Depending on the type of liquid stored in the underground tank, there is a custom liner made of the right material to handle the liquid. Materials used in linings include fiberglass, rubber, plastisol, Hypalon, PVC, vinyl ester, Koroseal, Chlorobutyl and phenolic.

Regulations

The Department of Environmental Protection regulates some underground tanks but not all. Residential tanks under 110 gallons of liquid and noncommercial motor fuel tanks under 1,100 gallons are not regulated. The EPA doesn’t regulate overfill tanks, flow-through process tanks or emergency spill tanks. Whatever doesn’t meet those requirements is regulated by the EPA from the tank to the piping.

Compliance

The EPA is most concerned with leaks from the tanks or pipes. Chemicals and oil prevent an environmental hazard. When a spill occurs, the environment surrounding the spill may experience damage. The EPA recommends regular tank maintenance including checking the tank lining. A custom lining helps prevent leaks and improves the tank’s integrity.

Underground storage tanks are all around us on residential properties, farms and industrial complexes. Preventing leaks and spills saves the owner time and money. Proper tank maintenance helps protect the environment from harmful substances leaking from the tank.
