Point Source(s) Notes Amount of Release

No Information Given

Followup: No

Notes: Hazmat incident #05-05935

No LDEQ Reported

waste water treatment plant
Cause: Torrential rains associated with Hurricane Gustave caused in Placid's waste water treatment facility resulting in sheen on the Missippi river.

Followup: No

Notes: remedical actions taken, or to be taken to stop unauthorized discharges or recover pollutants.

No Information Given

Wastewater treatment facility
Cause: STORMS-Torrential associated with Hurricane Gustav

Followup: No

Notes: Rain caused upset in facilitys waste water treatment facility causing visible oil sheen on the Mississippi


Wastewater treatment facility
Cause: Torrential rains caused waste water bypass

Followup: No

Notes: Placid's contract response organization was activated to respond to any potential discharge resulting from this bypass.
Oil: 235.8 pounds

Wastewater treatment facility
Cause: Torrential rains

Followup: No

Notes: Torrential rains overwhelmed the waste water treament system causing necessary temporary bypass


No Information Given
Cause: Initial notification to report potential permit exceedances for permits: LPDES LA0039390 - due to excessive rainfall. Written report states that "thankfully it appears at this time none of the parameters listed in [permit] were exceeded. Placid was able to manage the excessive water and no by-pass condition was necessary."

Followup: No

Notes: BRQ. No information given.


Tank No. 946
Cause: Due to excess rainfall associated with Hurricane Isaac on August 31, 2012, Placid diverted excess storm water from a permitted wastewater tank No. 940 to an unpermitted out of service clean open top tank No. 946. Approximately 4,200 barrels of water was transferred to prevent an overflow of tank No. 940 an/or tank No. 17, Placid's two permitted wastewater tanks. Placid's process units were in hot circulation mode and feed was removed from the process units due to the storm. The suction line used to transfer the water from tank No. 940 to tank No. 946 was located in the middle of the tank to minimize carryover of sludge or floating oil.

Followup: No

Notes: The water was transferred back from tank No, 946 to tank No. 940 on September 5, 2012. Movement of storm water into tank No. 946 was necessary to prevent a bypass condition in the Refinery waste water plant and to prevent potential adverse environmental impact and.or severe property damage. Placid's current LPDES permit provides for prohibition of bypass where feasible retention of untreated wastes is an alternative. Stormwater was diverted to a wastewater tank and therefore the pollutant becomes wastewater rather than stormwater. An attached document provides water emission calculations for Tank 946 and shows a total of 5.88 lbs/day daily emissions for total VOC released. No emissions were reportable quantity.

sump pump
Cause: Due to heavy rains, a sump pump in the tank farm was unable to keep up with the rainfall and overflowed into containment.

Followup: No

Notes: Absorbent materials were used to "corral" the oil floating on the rainwater. The oil was vacuumed off of the water and reintroduced into the process. Contaminated areas were cleaned with absorbent pads. An engineering study is in process to redesign the sump and associated pumps and piping.
Slop Oil: 210.0 gallons
No LDEQ Reported

North Dock Sump Pumps
Cause: During an extreme rainfall event, Placid's North Dock Sump was overwhelmed with water and overflowed into the Mississippi River, spilling an estimated 10-15 gallons of Crude Oil. The North Dock Sump Pump was unable to keep up with the heavy amount of rainfall.

Followup: No

Notes: To prevent reoccurrence, the North Dock Sump Pumps will be upgraded to new pumps that will have increased flow and discharge pressure. New pumps have been bid out and will be ordered on May 20, 2013. Design of the installation of these new pumps has been started and installation will begin upon delivery.
Crude Oil: 15.0 gallons

tank farm, sump pump
Cause: A sump pump in the tank farm was unable to keep up with heavy rainfall and therefore material overflowed into containment. No chemicals were emitted into air.

Followup: No

Notes: Absorbent materials were used to "corral" the oil floating on the rainwater. The oil was vacuumed off of the water and reintroduced into the process. Contaminated areas were cleaned with absorbent pads and boom. "Placid is continuing to evaluate/modify/improve its water systems"
Slop Oil: 210.0 gallons

Internal Sump, Outfall 006
Cause: Report indicates that on 1/13/14 an oily sheen was noticed in the ditches on the south side of the facility new Outfall 006. Upon review, Placid's internal sump had an oil sheen. Placid beleives heavy rains may have washed oil to the sump. Later in the report Placid indicates that the discharge was a result of an operational error.

Followup: No

Notes: Immediate remediation consisted of turning off the outfall pump and placing booms and absorbent materials in the ditches. An air pump was used to remove the floating sheen from the sump while the sump was out of service during clean up. The refinery reports that their future remedy is that Placid's Operations Department will pay closer attention to internal sumps during periods of heavy rainfall. This report was included in the same document as another discharge event with the same DEQ and LSP incident numbers. These cases occurred at different times in different places in the refinery and do not appear to be related. To differentiate the cases in this database this case is referred to as DEQ#1532250 while the first case is DEQ#153225. No state police reports were located for either incident.
