Site Description and Location
On September 10, 2012, a community activist contacted EPA concerning a noxious odor near the intersection of Liebold Street and Pleasant Street in southwest Detroit reportedly coming from the Marathon Refinery. The activist reported that the odors had started on Saturday, September 8.
EPA contacted Marathon's Environmental Supervisor Honor Sheard who reported that Marathon was in planned shutdown mode and was in the process of major retooling and steaming cleaning of the crude units. The cleaning had started on Saturday, September 8, and would be completed by midnight, September 10. Marathon had seen no increases at their perimeter air monitoring (PAM) stations, but was aware of an odor. Using AreaReas, Marathon had performed community air monitoring on September 8 and 9. Ms. Sheard said Marathon would do additional air monitoring in the Pleasant Street neighborhood.
EPA contacted Michigan DEQ's Jorge Acevado. Mr. Acevedo stated that a DEQ inspector had gone to the reported area, confirmed the odor, and DEQ would be issuing Marathon a Notice of Violation (NOV) for the odor.
EPA sent an OSC and an air sampling team to the reported area to collected samples. One sample was collected at the intersection of Liebold Street and Pleasant Street, one sample was collected at the Marathon fence perimeter, and one sample was collected upwind.

Response Action Results
Marathon reported no exceedances at the PAMs united; however, Marathon's community air monitoring found low level VOCs on September 8, 9, 10, and 11. While Marathon does collects 24-hour Summa canisters every 6 days, the collection dates were outside the September 8 through 10 time frame when the odor complaints occurred.
While EPA and DEQ personnel did detect the odor, the three samples collected by EPA on September 10 did not show exceedances. EPA's handheld mutliRAE also showed no exceedances.
Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
While the clean out process appears to have caused the odor, laboratory analytical results did not show exceedances, and the cleaning is complete. According to the DEQ, Marathon will receive an NOV for the odor.
