Secondary containment definition

Secondary containment or “secondarily contained” means a release prevention and release detection system for a tank or piping. This system has an inner and outer barrier with an interstitial space that is monitored for leaks. This term includes containment sumps when used for interstitial monitoring of piping.
Secondary containment means an approved barrier installed around a storage tank system that is designed to prevent a leak from the primary tank or piping from contacting the sur- rounding earth or the waters of the state before the leak can be detected and cleaned up.
Secondary containment means the level of containment external to, and separate from, the primary containment.

Secondary containment means a release prevention and release detection system for an underground storage tank or piping or both, that provides an inner barrier, an outer barrier, and an interstitial space between the two barriers for monitoring to detect the presence of a leak or release of regulated substances from the underground storage tank or piping, or both.

Secondary containment means a system installed around a petroleum storage tank or system that is designed to prevent a release from migrating beyond the secondary containment system outer wall (in the case of a double-walled tank system) or excavation area (in the case of a liner or vault system) before the release can be detected. Such a system may include, but is not limited to, impervious barriers (both natural and synthetic), double walls, or vaults.
Secondary containment means a release prevention system for tanks and piping consisting of an inner barrier and an outer bar- rier with an interstitial space capable of being monitored for leaks. This term includes containment sumps when used for interstitial moni- toring of piping.
