If you are considering an underground tank installation, you should know a few things. These types of tanks are considered cheaper to install, and they are less regulated. However, a new trend in tank installation may change all that. Read on for more information.

They are a Trend in the 1990s

In the 1990s, a new regulatory program from the Environmental Protection Agency (EPA) caused significant changes in the tank industry. Manufacturers were quick to release new enhancements to their UST systems. The EPA deadline was one of the most influential factors driving the growth of UST systems. While many small service station operators used this deadline as an excuse to close their doors, others embraced new designs and committed to underground storage for the long haul. Still, a growing number of tank owners were wary of the new designs and questioning the need for underground storage.

Concern about the environment spurred the development of new technologies for the underground storage of hazardous liquids. In particular, the design of steel tanks became more environmentally friendly. They were fabricated with a second wall and non-metallic jackets. Additionally, thick urethane or FRP-coated tanks without anodes became popular. Another famous cathodic-protected tank was the STI’s sit-P3(r).

They are Useless for Protection Against Corrosion

The concrete pad surrounding the underground tank is not sufficient protection against corrosion of the tank bottom. Water can easily infiltrate the pad, causing bacteria, chlorides, and sulfates to accumulate. This moisture will lead to tank bottom failure if left unchecked. In such a situation, cathodic protection is useless.

When fire codes were lax in the late 1970s, installing underground tanks from underground tank installation Westchester County NY without any corrosion protection was possible. Even well-coated steel tanks were not protected from corrosion if they were cathodically protected. Moreover, the corrosivity of the soil played a role in determining the kind of protection that was required.

Despite the presence of anodes, corrosion protection is still ineffective in most underground environments. There was a period when magnesium anodes did not work in underground environments. This led some entrepreneurs to develop a kit that incorporated a magnesium anode, but they found little success in the market. However, the growth of motorized vehicles increased the need for service stations, and petroleum marketers needed larger fuel tanks. The average size of an atmospheric tank increased to nearly 4,000 gallons by the 1960s.

They are Regulated by the U.S. Code

The US regulates underground tank installation. Code, which is a code of federal laws. This Code regulates the placement and use of underground storage tanks in regulated areas. It also covers the storage and disposal of waste from underground tanks. Under the Code, any state may prohibit certain materials from being deposited, accepted, or delivered into an underground tank. In addition, states may have time limits or criteria for banning sure products from entering underground tanks.

A tank must be equipped with a liquid-tight spill bucket around the fill pipe. These buckets must be kept free of debris or stormwater, and spilled products must be disposed of properly. Additionally, tanks must be equipped with a drop tube for proper drainage. For underground storage tanks, a high-level alarm and an automatic shutoff device are required. A flow restrictor device in the vent line is also required. If a ball float device is already installed in the underground tank, it is permitted to use it if it functions properly.

Under the Code, underground storage tanks must be registered and managed following the regulations. Under the Energy Policy Act of 2005, the Energy Department has expanded the list of eligible uses for the Leaking Underground Storage Tank (LUST) Trust Fund. It has adopted regulations related to operator training and financial responsibility. The Code also provides regulations for the cleanup of USTs containing oxygenated fuel additives.
