2013-12-16		Flange leak on caustic line
Cause: On December 16, 2013, a flange leak was discovered on a caustic line that supplies several units across the Norco complex. Immediately the caustic transfer was stopped and the leak slowed down. One barrel of caustic was estimated to be released within the Norco complex property.

Followup: No

Notes: A gasket was replaced on the flange and the pipeline was placed back into service without any additional issue. The soil and gravel in the area were remediated. Final observations and calculations confirm that no permit limits and no reportable quantities were exceeded during the event.
