1.1.1 Incident Category
Removal Assessment

1.1.2 Site Description
The site is located in a commercial and residential area in Frankfort, IN. An unknown amount of oil has leaked into Prairie Creek from a seep located along the west bank of the creek. The seep seems to be slowly leaking oil, creating a visible sheen on the water's surface.

1.1.2.1 Location
N. Jackson St & E. Morrison St, Frankfort, IN

Latitude: 40.2835317 Longitude: -86.5107471

1.1.2.2 Description of Threat
An oil seep was identified on the west bank of Prairie Creek while the Clinton County highway department was excavating the area for the construction of a new bridge over the creek. The Indiana Department of Environmental Management (IDEM) Emergency Response (ER) reported the seepage of oil along the bank of Prairie Creek to the U.S. Environmental Protection Agency (EPA). The EPA will continue to investigate the possible source of oil enter Prairie Creek.

1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results

On January 8, 2016, IDEM ER reported a seepage of oil along the bank of Prairie Creek in Clinton County, Frankfort, Indiana. IDEM ER has been working with the County/consultant, BLN, on designs for a slurry wall/sheet pilling, but IDEM ER requested EPA assistance since the source of oil may not be encountered or removed during the County's construction.

EPA OSC Anita L. Boseman and personnel from the Superfund Technical Assessment and Response Team (START) visited the site on Tuesday, February 2, 2016, to obtain written access and investigate the source of the oil seepage. A water sample of the visual impacts was collected from the creek as well as a sheen sample from along the stream bank.

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.
