A Schneider Foods transport truck (owned by Maple Leaf Foods Inc.) was involved in a collision while enroute to Brantford, Ontario. The transport truck was struck by a vehicle on the passenger side and the fuel tank was ruptured.  As a result of the ruptured fuel tank, an estimated 620 litres of diesel fuel was spilled onto the asphalt and concrete curb spillway along the highway. The path of the spill was directed along the spillway to two connected downgradient catch basins, which released through a culvert into a surface water drainage ditch. Surface water carried the remainder of the diesel fuel into three additional culverts and drainage ditches that ultimately discharged into two marsh areas.

Newalta Emergency Spill Response team was contacted and arrived at the site within a half hour of the initial spill and proceeded to immediately contain and collect the released product. Over a period of two days, they collected oily water from the catch basins, ditches, and downgradient marsh areas. Soil was also scraped from the ditches and disposed off-site. Oil sorbent pads and oil booms were placed in various locations down-gradient in the catch basins, ditch locations, and down-gradient culvert entry and outlet points to contain the remaining oil sheen. An underflow dam was constructed to contain any remaining oily sheen up-gradient of the marsh area.
XCG met with the Newalta Emergency Spill Response team immediately following the spill and collected surface water samples from upgradient of the site, at culvert outflows and from within the marsh areas. Sediment samples were also collected at each surface water location. These surface water and sediment samples were collected prior to the majority of the clean-up being completed and were considered worst case. Following the removal of the oily water and excavation of the sediment, XCG made visual observation with regard to sheen and collected confirmatory surface water and sediment samples for laboratory analysis. Trace oil sheen was observed at one culvert outflow; therefore, the oil booms and sorbent pads were left in place for another week. No further sheen was observed the following week and the oil booms and sorbent pads were removed.

The analytical results for sediment and surface water, combined with the observed activities by the emergency response contractors indicated that Maple Leaf Foods Inc. had responsibly mitigated any impacts that may have been created by the diesel fuel spill resulting from the collision. No further activities were recommended.
