Releases of Hydrogen Cyanide

LDEQ Accident Number
Accident Date		 Point Source(s) Notes Amount of Release
149447

2013-07-01		FCC Regenerator RLP0057
Cause: Due to a change in estimating methodology based on a proactive analysis of stack test data from other facilities, the Phillips 66 Lake Charles Refinery believes that the HCN emissions from our refinery are above the reportable quantity of 10 lbs/day. The continuous release being reported is not the result of a malfunction or any change in operations but rather is due to a change in estimating methodology. These emissions occur during normal operations and, in our best professional judgement; these emissions are stable in quantity and rate during normal operations.

Followup: No

Notes: Phillips 66 Lake Charles are evaluating applicable requirements to determine if these HCN emissions meet the federally-permitted release exemption.		640.8 pounds
