Continuous Release Detection (CRDM) Defined
- CRDM is a way of detecting a release of liquid through the inherent design. This does not require sensors or power to operate. Liquid releases can be visually detected by site personnel. There are 3 common acceptable CRDM systems:
- Tank with Release Prevention Barrier including poly barriers & concrete pads
- Secondary Containment AST, which include double-wall ASTs & double-bottom ASTs
- Elevated AST with RPB
