|LDEQ Accident Number
|Point Source(s)||Notes||Amount of Release|
|Brine Hold Tank||Cause: Tubing came apart while transferring G-123 from a drum to the Brine Hole Tanks. Tank began to release G-123 to the area below.|
Notes: Employee found the material overflowing and closed the valve under the tank. Absorbent was placed around the sump to absorb additional G-123 from entering into the freshwater outfall. The diversion gate at Outfall 003 was closed to divert water to the Plant's ETF system for treatment. Approximately 4642 pounds were released from the tank. Approximately 2190 pounds were released to the atmosphere with the remaining being diverted to the Plant's ETF for treatment.
|piping on No. 46 G-113 crude tank||Cause: A leak was discovered from a section of piping located at the bottom of the No. 46 113 crude tank. Release was caused by a small hole that had developed on a flange of the storage tank.|
Notes: Release was secured within 30 minutes by installing a clamp on the section of the piping.
|relief valve-343||Cause: The G-1113 production unit experienced a pressure drop during a time when the unit was down and not operating. Pressure relief valve-343 was leaking.|
Notes: Condenser relief valve was switched to the spare and the leak was isolated. At the onset of, and for the duration of the event, the unit was in a blocked in state with no feed additions. The relief valve has been sent off for testing to confirm the failure.
|relief valve||Cause: Relief valve from the organic recycle vaporizer was leaking. Release occurred what a relief valve on a vapor riser lifted releasing a small amount of chemical into the air. Leak lasted about 10 min.|
Notes: The relief valve was immediately blocked in and removed for repair and the spare relief valve was placed into service.
|tank car loading/unloading area||Cause: Approximately 14578 lbs of Trichlorotrifluoroethane was released due to a gasket failure in the load/transfer hose while filling the tankcar.|
Notes: The chemical was released onto the railroad tracks, cross ties, gravel and soil underneath the tank car. The product was initially contained by a large dyke of oil dry. MasterVac had been called to vacuum up the product. Gravel and soil had been dug up to about a foot, new soil had been added, and gravel was being placed back in the track bed. The new cross ties were being laid in place. The soil/gravel had been placed into a rolloff and the cross ties had been placed into another rolloff. The two roll offs were going to Waste Management. The liquid product that was recovered had been placed into a drum. The drum was to be sent for incineration.
|Brine Hold Tank||Cause: Leak in the G-1113 unit at the brine jacket relief valve on the brine pump tank. At the time of the leak, the G1113 unit was shutdown and the brine system was in circulation mode causing the unit to lose cooling water. The loss of cooling water caused by the brine temperature to increase and pressure up the brine hold tank resulting in the pressure relief valve lifting.|
Notes: G1113 unit was shutdown and the brine system was in circulation mode. Circulating pump was immediately shutdown to seat the relief valve. The liquid portion of the leak was contained in the sump and containment area with a 2069 gallon capacity. As a precaution, the diversion gate to stormwater outfall 003 was closed and water was diverted for on-site treatment. Honeywell has modified its operating procedures to shutdown the brine pumps in the event the unit is down for an extended period greater than 6 hours. Long term plans are to redesign the pressure safety valves to add an additional layer of protection to prevent release to atmosphere.
