Case Studies > Emergency Response Case Study
At 4:15 am on August 24th, a tractor-trailer was involved in a one-vehicle accident in Atlanta, Georgia. The tractor-trailer contained 85 drums of hazardous materials comprised of various “D, F and K” listed wastes. Due to the accident, the trailer body was breached and 79 of the drums were ejected onto the ramp embankment in an area approximately 150 ft by 150 ft between two interstates. Six to nine drums were breached spilling their contents onto the soil within the highway median.
Federal regulations applicable to this incident include Part 263 of 40 CFR. State regulations that may apply are the Solid Waste Disposal Act, Toxic Substance Control Act, and the Hazardous Site Response Act. Emergency response activities were initiated which included collection and over-packing of all drums, along with excavation of impacted soils. Approximately 223 tons of soil were excavated and containerized in steel roll-off containers. Mitigation, cleanup, and site stabilizations activities were complete within 72 hours of the spill.
Laboratory analysis of soil samples including RCRA Total Metals and TCLP Metals indicate that metals in soil had been remediated by removal and that remaining levels of metals are indistinguishable from background concentrations. Minor concentrations of volatiles remained in the soil. Upon presentation of the preliminary investigation and laboratory data to the Georgia Environmental Protection Division Emergency Response Program Manager, a ”No Further Action” was awarded.
