On August 27, 2007, the National Response Center notified the United States Coast Guard (USCG) of a fuel truck spill in Corpus Christi, Nueces County, Texas. A truck transport owned by Enterprise Transport was reported to have had a vehicular accident, at 0930, at the northbound exit ramp at the intersection of I-37 and US-181. The vehicular accident caused the 6,600 gallon tank to rupture and discharging approximately 5,800 gallons of #6 diesel fuel oil. The fuel oil threatened to flow though a storm sewer directly into Corpus Christi Bay. Although a small amount of fuel oil did get into the storm sewer, the Corpus Christi Fire Department responded and constructed berms to contain the oil. The area experienced rain showers during the initial response effort, which threatened to further exacerbate the situation.
EPA mobilized OSC Leos and the EPA Superfund Technical Assessment and Response Team (START) to the site to assess the reported spill and coordinate with Texas Commission on Environmental Quality (TCEQ).
On September 5, 2007 all remediation activities had been completed by the Potentially Responsible Party’s (PRP) remediation contractor, Miller Environmental and associated subcontractors.
Between the time period of August 28, 2007 and September 5, 2007; Miller Environmental began remediation by physically removing diesel impacted soil, conducting a visual confirmation that the impacted soil had been removed, and sampling all remaining soil to ensure that state and federal clean up goals have been met. To remediate the support columns, Miller Environmental positioned scaffolding and plastic sheeting around all US-181 support columns that had been impacted by the diesel. The support columns were pressure washed with hot water (approximately 140 degrees), and the water impacted with diesel was captured on plastic sheeting below the columns and removed with a vacuum truck. The concrete decline was remediated utilizing a pressure washer containing hot water to remove the fuel oil from the concrete. Oily water runoff that comes in contact with the fuel oil is captured in a clay lined sump located at the bottom of the decline and recovered by vacuum truck for offsite transportation and disposal.
Sample results taken from the areas where the soil had been removed is pending.
On September 10, 2007, a final walk through was performed to observed work completed. No oil was observed on scene.
No further EPA action is anticipated.
