2006-10-29
Point Source(s):
AE-AOA-05-0109 EPN 28

Pollutant(s):
Nitrogen Oxide - 24 pounds
Cause of Problem: Equipment Failure

mechanical failure in the check valve servicing the K-7702 Compressor. Make-up Discharge Check Valve mechanically failed and allowed the system to pressure back into the compressor. The resulting surge in pressure to the compressor caused the pressure safety valve on the first and second stage to relieve.
PSV was isolated until it rescated and lined back up to the compressor. During the next turnaround on the CFHT or shutdown, the valve for the K-7702 compressor will be replaced.

2006-10-17
Point Source(s):
AE-AOA-05-0109 EPN 29

Pollutant(s):
Sulfur Dioxide - 30 pounds
Nitrogen Oxide - 8,293 pounds
Cause of Problem: Maintenance/Procedures

release occurs during major turn around of refinery. Planned system outages created higher than usual operating pressure on the WGS and AMU. Additionally, on 10/13, the stream was re-routed (misaligned) through a line with an unidentified check valve. Subsequent attempts to push liquid through the AMU line resulted in increased pressure on the WGS.
Investigation ongoing. PSV set pressure was raised to allow for higher head pressure events at WGS without flaring. Detailed investigation ongoing.

Point Source(s):
Thermal Oxidizer and Flare 1 - AE-AOA-05-0109 EPN 46

Pollutant(s):
Nitrogen Dioxide - 352 pounds
Hydrogen Sulfide - 2,917 pounds
Nitrogen Oxide - 3,198 pounds
Sulfur Dioxide - 1,068,405 pounds
Cause of Problem: Process Upset

Discharges came from THOX and Flare 1. The Amine and Sulfur Recovery Units were upset. It was determined that hydrocarbons contaminated the Diglycolamine (DGAš) and required both units to be taken offline. The upset caused excess emissions from the SRU 1 Thermal Oxidizer (THOX). Sulfer Plant feed was diverted to the refinery safety flare system while the conditions which cause the upset were isloated and remedied. CRLLC reduced the rates of acid gas productin units to minimum and lowered total sufer content of remaining feed, within refinery capability.
CITIZEN COMPLAINT COINCIDES WITH INCIDENT - all acid gas producing units were cut back to minimum rates. The source of hydrocarbon in the DGA system was isolated and then purged. The refinery has initiated an investigation into the cause of this incident. Based on the result of that investigation, appropriate measures will be take in order to prevent a recurrence dut ot the same cause.

2006-10-04
Point Source(s):
Fract Tank

Pollutant(s):
Oil - 423 pounds
Cause of Problem: Maintenance/Procedures

vacuum tower was rinsed with hydrotreated light crude Oil to thin out the crude residue and then rinsed with water and detergent to remove the Oil and crude. The Oil was floating at the top of the fract tank at the tim of overfill. A containment berm had been set up around the fract tank to contain unforeseen leaks. Some Oil still landed outside the berm
rac tank has bee removed other tank levels will be monitored during transfers for the remainder of the turnaround. An environmental bulletin will be developed and discussed during crew talks to increase awareness fo the remporary containment issues and extra precautions needed during trunaround activities in order to prevent spills.

Point Source(s):
#2 Flare - AE-AOA-05-0109 EPN 29

Pollutant(s):
Nitrogen Dioxide - 30 pounds
Cause of Problem: Maintenance/Procedures

FCCU PGC was tripped during maintenance activities resulting from a fire on Sept. 25, 2006 (incident number 06-06025). When replacing burnt conduit, PGC shut down and resulted in an increased back pressure on the Naphtha stripper tower. PSV lifted to flare 2.
