As an update to the Bloomberg News report

regarding the ExxonMobil Chalmette refinery October 4, 2010 offsite air monitoring which detected 21 to 40 parts per billion........... see State Police Hazmat report below, which states the chemical went offsite and was detected at 21 to 40 parts per million.

State Police Hazmat Report


ExxonMobil reported two previous releases of Compressed Flammable Gas at the end of September 2010.

Sept 20, 2010 Incident T126494 EDMS 49618483 AI# 1376 dated 9/27/2010, notification of release of Compressed Flammable Gas and hydrogen sulfide from Sept 20 through Sept 22, 2010. ExxonMobil reports this is a courtesy notification because the quantities released in any one 24 hour period did not exceed the RQ or reportable quantity.
(I'm not convinced the reportable quantity is per 24 hour and not per release.) http://edms.deq.louisiana.gov/app/doc/view.aspx?doc=49618483

Sept 29, 2010 Incident T126762 EDMS 49722602 dated 10/06/2010, notification of release of Compressed Flammable Gas and SO2. Due to prompt incident response to mitigate the event duration, no reportable quantities were exceeded.
(Wondering which event involved the first clamp? the Sept 20th or the Sept 29th release? or if these are even related?) http://edms.deq.louisiana.gov/app/doc/view.aspx?doc=49722602

<http://www.surveymonkey.com/i/t.gif> At ConocoPhillips in Lake Charles in 2007, one worker died because of a chemical reaction during a transfer of Hydrogen Sulfide into a truck. Nine others were taken to the hospital. But because only 83 pounds were released and this was below the state’s reportable quantity for Hydrogen Sulfide, the refinery gave no further details on the matter. (Louisiana Bucket Brigade Refinery Efficiency Initiative Database http://farm.ewg.org/sites/labb/incident.php?serno=933 ).

Does anyone else think the State of Louisiana should change the reporting requirements during these types of accidents?
