ON July 15, 2013, an upset in Crude Unit 210 caused the Crude Compressor Suction Drum to vent to the North Ground Flare for approximately one minute. The first incident was due to a crude oil switch causing the Unit 22 Sats Gas Plant Compressor to shutdown on high level. The second incident was due to an upset in the Unit 210 Crude Unit that cause the Unit 210 Crude Compressor Suction Drum to vent to the North Ground Flare.
Operating personnel made operating changes to the unit to bring it out of upset conditions. October 23, 2013 additional follow-up report corrects emissions data submitted by MPC. MPC erroneously included greenhouse gas (GHG) emissions in the incident calculation. GHGs are not permitted pollutant and are not required to be evaluated for reportable quantities.
