Narrative

In coordination with the Detroit Hazmat Team, U.S. EPA deployed AREA REAs in the immediate area of the fire and sent air monitoring teams into the evacuated areas and beyond.  Based on a National Atmospheric Release Advisory Center (NARAC) model and input from Michigan Department of Community Health and the Agency for Toxic Substance and Disease Registry, SUMMA canisters and filter samples were placed in the fallout area to collect metal, particulate, VOC, and SVOC samples. While real-time VOC readings were found immediately adjacent to the fire, no elevated readings were detected in the evacuated areas or beyond.  Laboratory sample data from the filters and SUMMAs is pending.

 At 1430 hours the fire was extinguished by use of foam provided by Marathon Oil Company through mutual aid.  Based on concurrence from health agencies, the IC lifted the evacuation at 1700 hours. U.S. EPA and CTEH air monitoring continued until 0800 on August 28 – no elevated readings were found.  U.S. EPA also attempted to sample the downwind fallout, but not enough material could be located.

In coordination with the Detroit Water Department, U.S. EPA conducted monitoring in the sewer system. Finding both elevated LEL and VOC readings at multiple locations along Woodland Street and Commor Street, U.S. EPA directed the PRP to begin flushing and vacuuming the sewer, which continued until 0600 hours on August 28. Based on a concern that petroleum contaminated run-off may have entered basements, U.S. EPA conducted LEL and VOC monitoring in adjacent residential basements. No elevated readings were found.
