Liquid/Solid Release to Water

Typically an unauthorized release of fluid not allowed by applicable facility permits and regulations. Process safety indicators (Tier 1 & 2) are used to measure such loss of containment events.  This could include simple unauthorized runoff water to a water course, river or local water body. Similarly, it could involve an unauthorized  release of drilling fluids. Authorized releases can include discharges to rivers or the ocean, provided specific standards are met as to volume, chemical content, oil & grease content, etc.
