1.1.1 Incident Category
This incident is an OPA emergency response. Activities include the assessment and the removal of multiple oil discharges at various oil production facilities as a result of flooding associated with Tropical Storm Bill that impacted tank batteries and compromised aboveground storage tanks (ASTs).
1.1.2 Site Description
The assessment and removal addresses oil discharges from multiple tank batteries and wells by multiple Responsible Parties (RPs).
1.1.2.1 Location
EPA’s assessment activities are within the flood impacted area of approximately 21.1 miles along the Walnut Creek/Bayou, beginning at approximately 34.202392°, -97.398670° to 34.071279°, -97.294504°.
Oil spill response efforts are concentrated south of the Tripledee Operating Co. Ramsay Williams Lease, located at 34.161040°, -97.329570°, and the Kingery Drilling Newman Lease, located 34.158789°, -97.325117°. Although some portion of these oil impacts appear to have originated from the two tank batteries, oil discharged upstream may have been mixed in.
The flood impacted area is a heavily wooded rural area west of Lone Grove (Carter County), Oklahoma, with an estimated population of 5,054 (2010 census).
1.1.2.2 Description of Threat
On 17 June 2015, Tropical Storm Bill, a tropical cyclone, made landfall on Matagorda Island, Texas, producing widespread rainfall across East Texas and Oklahoma. The local National Weather Service office issued a flash flood emergency for the area after 4 to 8 inches (100 and 200 mm) of rain fell in Carter County, Oklahoma. Rainfall totals from this storm ranged from 9.53” in Ardmore, OK to 13.63’ in Newport, OK. As result of the heavy rainfall in the area, including Carter, Love, Johnston, and Marshall Counties, multiple oil discharges from oil production sites were reported by operators in the area. FEMA is currently developing flood maps of the impacted area to determine the extent of flooding and the magnitude of the event believed to be in excess of a 100 year storm. FEMA did not activate ESF #10.
The flooding swept away ASTs that stored oil from production fields in the area. It is estimated that more than 400 bbls of oil is unaccounted for. EPA received 5 of NRC reports for oil discharges and the Oklahoma Corporation Commission (OCC) has received 13 complaints, in this area.
Oil that was discharged into the flood waters would have flowed into Walnut Creek/Bayou, which flows to the Red River and then into Lake Texoma. Walnut Creek/Bayou and the Red River are navigable waters of the U.S.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
On 26 June 2015, EPA and the OCC conducted an aerial overflight and began ground assessments to determine the extent of impact of oil. A concentration of oil spill impacts are located in an area south of Highway 70 along the Walnut Creek/Bayou, specifically south of the Tripledee Operating Co. Ramsay Williams Lease, located at 34.161040°, -97.329570°, and the Kingery Drilling Newman Lease, located 34.158789°, -97.325117°.
