EDMS 44926543 dated 12/21/2009 Incident T120104 Dec 14 2009 storage tank cover collapsed
31,274 pounds of VOC's and 616 pounds of benzeneOn December 14 2009 there was a release of 10,967 barrels of gasoline to the roof of Tank 200-1( state hazmat Dec 14 2009 storage tank roof collapsed. ) For approximately 2.8 hours until the tank was pumped down to its lowest level, initial estimated emissions are 31,274 pounds of VOC's and 616 pounds of benzene.

EDMS 44922633 Dated 12/18/2009 T120127 December 13 2009 diesel oil release into neighborhood canal.
No quantity of diesel released nor benzene or VOC emissions reported. On December 11 2009 Murphy was forced to open Outfall 003 due to prolonged rains. also reports on December 13 2009 Murphy Oil made a discovery of oil in a neighborhood canal. Murphy Oil discovered a release of diesel-like oily water on the 20 arpent canal, reported by Murphy Oil as ""presumably from Outfall 003"".The refinery storm water outfalls on page two of the flowchart indicates emergency outfall 003 due east of the Collin's Pipeline area. Collin's Pipeline is a joint venture of EXXON-Houston and Murphy Oil Meraux. To the west of Collin's Pipeline area is the municipal storm drainage pipe which released the diesel oil into the neighborhood canal, named 20 arpent canal, where it intersects Jacob Drive. It is unclear at this time how the diesel oil entered the municipal storm water system. There is no quantity of diesel released nor benzene or VOC emissions reported.
Residents have requested water, soil and air sample results from Louisiana Dept of Environmental Quality. It is unclear if any samples were taken by the state department.During the same time Murphy Oil Tank 250-2 was scheduled for a cleanout with use of a temporary, portable diesel fuel tank EDMS 44548567.

EDMS 43986164 Dated 10/26/2009 Incident T118824 Oct 19 2009 crude oil spill tank 250-1
130 barrel crude oil spill Tank 250-1 on Oct 19 2009 released to air 12/4 bbl; released to ground 11.6 bbl; estimated emissions 3.91 benzene; 3907 pounds VOC's (Residents called both Murphy Oil and LDEQ to come to the neighborhood about high level of chemical's present; both refused. Murphy reports their subcontractors were monitoring the air).

EDMS 44138747 dated 11/13/2009 Incident T119342 Oct 14 2009 FCCU leak (Late Report - also Benzene emissions rescinded EDMS 44922731 Dated 12/10/2009)
Cat Craker Unit leak releases 44,000 pounds hydrocarbons with 155 pounds benzene from Oct 14 - 17 2009 --- leak at upper manway in #2 FCCU Reactor (Cat Cracker or Hydrocracker) --Application of steam to disperse the vapors. First attempt to repair the leak failed on Oct 15 2009 and leak apparently worsened. Specialty group arrived Oct 16 2009 to measure the manway and access the leak. On Oct 17 2009, as Murphy awaited that repair, the leak worsened, so Murphy shut down the FCCU as a safety precaution. The vendor installed the clamp on Oct 18 2009. The leak was estimated to have lasted 74.5 hours from approximately 09:00 hrs on Oct 14 2009 to 11:300 hrs on Oct 17 2009 when the unit was shut down.Estimated hydrocarbon emissions 44,000 pounds with 155 pounds of benzene. Murphy Oil rescinded notification of benzene release Dec 10 2009. Murphy reported to the National Response Center that this event resulted in the release of benzene in excess of the 10 pounds reportable quantity. Murphy Oil provides Dec 10 2009 update to rescind benzene release notification citing CERCLA 101(14) for exemption from reporting benzene emissions.

EDMS 39896700 dated 1/16/2009 T111906 Refinery Power Interruption Jan 9 2009;The power interruption lasted less than one second, but triggered safety shutdowns in several units resulting in SO2 estimated esmmions at 235 pounds as well as visible emissions."The power interruption is under investigation. Unplanned shutdowns of units in this manner are undesirable to the refinery, so Murphy is determined to identify and correct the root cause.
