2010-03-12
Point Source(s):
Sheet Pile Wall

Pollutant(s):
Slop Oil - 3 gallons
Cause of Problem: Weather

DEQ report states, "approximately 3-5 gallons of emulsified slop oil washed through the lifting holes in the sheet pilings that separates the lagoon from the ship channel. According to Diana LeBlanc (Environmental Engineer) with Citgo, the oil was released from the bottom of the lagoon when Morrison surveyors were profiling the bottom of the lagoon." High winds caused oil to be driven from the surface of the Indian Marais Lagoon, to the sheet pile wall where it escaped into the Calcasieu River.
Report states that "Citgo immediately deployed hard and absorbent booms to capture the oil on both sides of the sheet pilings. The water level was pumped down by Citgo and sent to the wastewater treatment area to prevent any additional spillage from the lagoon. ES&H was contracted by Citgo to assist in boom deployment and cleanup. Ms. LeBlanc said that written notification would be forthcoming when the investigation was complete."
