2.1.1 Narrative
On January 8, 2016, the Indiana Department of Environmental Management Emergency Response (IDEM ER) reported a seepage of oil along the bank of Prairie Creek on Clinton County, Frankfort, Indiana and requested assistance from EPA.
The County highway department is constructing a new bridge crossing over Prairie Creek and encounter an oil seep from the Creek's western bank. IDEM ER has been working with the County on designs for a slurry wall/sheet piling.
On February 2, 2016 EPA responded to the report of the oil seepage. EPA and START visited the site to investigate the source of the oil seepage and to collect samples. OSC Anita Boseman also obtained written access to the site from the City of Frankfort.
2.1.2 Response Actions to Date
On February 2, 2016. EPA responded to the report of the oil seepage into Prairie Creek. OSC Anita Boseman and START collected a surface water and petroleum sheen net sample from where the oil had been seen leaking into Prairie Creek. Also present for the sampling was Pat Colcord with IDEM, and Brian Shaw with Beam, Longest & Neff (BLN), Clinton County's construction contractor. Each sample was screened with a MultiRAE Pro to detect possible toxic gases including volatile organic compounds (VOCs), hydrogen sulfide (H2S), oxygen (O2), carbon monoxide (CO), and lower explosive limit (LEL). No detections were seen from either sample.
The petroleum sheen net sample was sent as a dangerous good to the U.S. Marine Safety Laboratory for fingerprinting analysis. The surface water sample was sent to CT Laboratories, Inc. in Baraboo, Wisconsin to be analyzed for VOCs, semivolatile organic compounds (SVOCs), and polychlorinated biphenyls (PCBs).
Sample results of both the sheen net sample and surface water sample revealed no detections of VOCs or PCBs. Benzo(a)anthracene was detected at 0.12 ug/L in the surface water sample collected near the seep along the west bank of Prairie Creek, which is less than the EPA Removal Management Level for SVOCs in surface water.
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
EPA does not yet know all of the sources of the hazardous substance nor whether the oil has migrated to locations besides Prairie Creek. The parcels adjacent to the creek are owned by the Clinton County Board of Commissioners.
