The requirements set by The Environment Agency for Decommissioning an underground tank apply to all underground storage tanks and not just those used for the storage of fuels. [15] They give extensive guidance in The Blue Book and PETEL 65/34. The Environment Agency states that any tank no longer in use should be immediately decommissioned.
The major design codes for welded atmospheric tanks are API 650 and API 620. API 653 is used for analysis of in-service storage tanks. In Europe the applicable design code is EN 14015, which uses load cases from Eurocode 3 (EN 1993), part 4-2.
A stormwater detention vault is an underground structure designed to manage excess stormwater runoff on a developed site, often in an urban setting. This type of best management practice may be selected when there is insufficient space on the site to infiltrate the runoff or build a surface facility such as a detention basin or retention basin .
More than 516,000 leaks have been cleaned up since Congress directed EPA to begin regulating underground tanks in 1984, but more than 57,000 known sites still await a full cleanup, the EPA said.
It consists of 20 steel-lined underground storage tanks encased in concrete, and built into cavities that were mined inside of Red Hill. Each tank has a storage capacity of approximately 12.5 million gallons. The Red Hill tanks are connected to three gravity-fed pipelines that run 2.5 miles inside a tunnel to fueling piers at Pearl Harbor. Each ...
A dry well or drywell is an underground structure that disposes of unwanted water, most commonly surface runoff and stormwater, in some cases greywater or water used in a groundwater heat pump. It is a gravity-fed , vertical underground system that can capture surface water from impervious surfaces , then store and gradually infiltrate the ...

A number of metrics are used to define and measure the volume of an underground storage facility: Total gas storage capacity: It is the maximum volume of natural gas that can be stored at the storage facility. It is determined by several physical factors such as the reservoir volume, and also on the operating procedures and engineering methods ...
