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