What is a UST Tank?

An underground storage tank is a tank and its underground piping that is connected to the tank with a minimum of 10 percent of its collective volume underground.

The regulations of UST tanks vary and are based on if the system contains certain chemical materials like petroleum, methane, or solvents.

It’s useful to know that both the state and the federal regulations for UST tanks may be different.

Some tanks to note that are free from EPA regulations include overview tanks, septic tanks, process tanks, farm tanks, and residential tanks.

What is an AST Tank, or Aboveground Storage Tank?

An aboveground storage tank is a storage vessel that is aboveground.

It contains liquids like water, crude oils, gases, chemicals, and petroleum in large amounts.

AST tanks have firm platforms attached to them and stainless steel, fiberglass, or polyethylene make up their material.

Most tanks can hold up to 30,000,000 gallons of liquids.

To prevent any leakage or spilling to happen it contains a secondary vessel within.

All modern AST tanks carry a device that detects any sign of overflow or leak.

The aboveground storage tank, better known as a bulk storage container, have regulations by the 40 CFR 112.

How are UST and AST Tanks regulated?

Beginning in the 1980s, Subtitle I of the Solid Waste Disposal Act, is known for regulating UST tanks.

This regulation focuses on correct training, inspections, spill containment, and financial responsibility.

Since 2009, the members of Congress have been able to distribute $200 million from the Leaking Underground Storage fund to the EPA to take care of UST leaks around the U.S.

The EPA is always going through updates and revisions. This is so that the EPA can be sure to help prevent and catch UST releases.

These releases are the main causes of groundwater contamination. These revisions also change some key parts of the Energy Policy Act of 2005.

Aboveground storage tanks contain regulations by various federal and local requirements, as do USTs.

The state and local authorities apply these requirements.

There is no federal plan that regulates ASTs.AST tanks require additional state and local maintenance to protect the health of humans and any hazards.

If the tank contains any explosive liquids or petroleum product it is safe to say that you must have the Clean Air Act and make sure to follow the proper instructions on a federal level.
