Pollutant(s):
Benzene - 0
Toluene - 0
Ethylbenzene - 0
Xylene - 0
Cause of Problem: Maintenance/Procedures

BTEX (Benzene,Toluene,Ethylbenzene,Xylene) sample taken prior to discharging test water showed non-detect levels. However, a follow-up sample collected during the discharge disclosed levels above permitted levels of BTEX in water.
Facility is "working with the lab to avoid any reoccurrances". BTEX Levels equaled 401 ppb. Limit is 250 ppb. 151 ppb in excess.

Cause of Problem: Equipment Failure

There was a leak in the sample valve of UTLX Railcar No. 910150.
The MAP technician who discovered the leak attempted to tighten the valve but this just led to valve remaining open and inoperable. This event is currently under investigation. Water was sprayed on the railcar.

Organic Compounds - 24,916 pounds
Cause of Problem: Instrument Failure

It is suspected that there was a failed level indicator on 6/26/05 which led to the product being on the roof of the tank. The cause of the failure in unknown.
The product was transferred to a finished gasoline storage tank. The cause of the failure and subsequent leak are still unknown and are awaiting the results of the investigation.

2005-06-17
Point Source(s):
Regenerator Outlet piping in the Butane Isomerization Unit (no EPN)

Pollutant(s):
Isobutane - 8 pounds
Cause of Problem: Piping or Tubing

There was a pinhole leak in the regenerator pipeline tubing.
Regenerator was shut down and a clamp was installed on the line prior to returning the line to service. Below Reportable Quantities

Point Source(s):
No Information Given

Pollutant(s):
Tek-Flame - 15 gallons
Cause of Problem: Equipment Failure

A faulty level transmitter on the sump pump at the on-site Fire Training grounds and excessive rain water caused the sump to over-flow into an internal ditch."
BELOW REPORTABLE QUANTITIES. A boom was deployed to prevent the mixture (of Tek-Flame and rainwater) from spreading to the Refinery's external outfall. A vacuum truck removed the fuel/water mixture from the ditch. Incident is currently under investigation.

2005-05-28
Point Source(s):
North Flare (EIQ No. 83-74)

Pollutant(s):
Butane - 914
Hydrogen Sulfide - 26
Sulfur Dioxide - 49
Cause of Problem: Process Upset

The regenerate stream from the Unit 28 Butane Isomerization Liquid Feed Drier was inadvertently blocked in. The Liquid Feed Drier then over-pressured and released to the flare.
The rundown line was opened up and the regenerate was routed to the Tank Farm to lower the pressure of the Liquid Feed Drier. This incident is currently under investigation.

2005-05-22
Point Source(s):
Thermal Oxidizer Cap (no EPN)

Pollutant(s):
Hydrogen Sulfide - 0 pounds
Cause of Problem: Process Upset

A local pressure controller in Unit 19 (Amine/Sour Water Stripper) closed due to high pressure and stopped amine flow to the Regenerator. Amine pump to Unit 15 (Heavy Gas Oil Hydrotreater) was tripped and the Unit 45 Sulfur Plant shut down due to the low amine acid flow. The sulfur plants all went off-ratio and began smoking 2 of the 3 Thermal Oxidizers , exceeding the opacity limit. The Unit 45 Sulfur Plant's Thermal Oxidizer then went below 900 F for app. 9 m which led to excess emissions of Hydrogen Sulfide.
An Air Monitoring Team was dispatched and no off-site impacts were found. Operations worked to get the Sulfur Plants back on ratio and minimized emissions. The incident is under investigation.

Cause of Problem: Human Factors

The Unit 42 boiler was inadvertently tripped, along with the air compressor, which caused an upset condition at the Unit 26-FCCU. During start-up of the unit, the Debutanizer overpressurized and vented to the North Flare.
"Operations personnel took all actions possible to minimize emissions."
