Interstitial monitoring definition

Interstitial monitoring means a leak detection method that entails the surveillance of the space between a tank system’s walls and the secondary containment system, for a change in steady−state conditions.

Interstitial monitoring means a leak detection method which entails the surveillance of the space between a UST sys- tem’s walls and the secondary containment system for a change in steady state conditions. In a double−walled tank, this change may be indicated by a loss of vacuum, a drop in pressure, a drop in the fluid level in a visible reservoir, or the detection of the regu- lated substance or water in the interstitial space or both. In a secon- dary containment system consisting of a natural or synthetic liner or a vault, the surveillance consists of frequent or continuous sam- pling from a monitoring well or interstitial monitor between the UST and the liner to detect the presence of regulated substance or water.

Interstitial monitoring means a leak detection method which entails the surveillance of the space between the underground storage tank system's walls and the secondary containment system for a change in the steady state conditions. In a double-walled tank, this change may be indicated by a loss of vacuum, a drop in pressure, a drop or rise in the fluid level in the visible reservoir, or the detection of regulated substances and/or water in the interstitial space. In a secondary containment system consisting of a liner (natural or synthetic) or a vault, the surveillance consists of frequent-to-continuous sampling of a monitoring well between the
