1.1.1 Incident Category
The preliminary assessment was conducted as an emergency under OPA.
1.1.2 Site Description
In May 2014, the EPA Region 8 Emergency Response Unit was asked to investigate a series of seeps, some actively bubbling, along the White River. Initial reports indicated a black, oil-like substance was discharging from the seeps and a possible sheen was observed. The seeps are located in the Natural Buttes field, an area of extensive oil and gas development. The White River is a tributary of the Green River and is home to several threatened and endangered species including the Colorado pike minnow and the razorback sucker.
1.1.2.1 Location
The seeps are located approximately 33 miles south of Vernal, Utah, along the White River at latitude/longitude 39.9835400, -109.4097670. The seeps are within the external boundaries of the Uintah and Ouray Indian Reservation on lands managed by the Utah School and Institutional Trust Lands Administration (SITLA).
1.1.2.2 Description of Threat
The seeps are potentially a discharge of oil under 40 CFR 110.3(b).
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
On July 9, 2014, EPA OSC Joyel Dhieux conducted a preliminary site assessment of the seeps. Representatives from the Utah Department of Environmental Quality, SITLA, Tri-County Health, Anadarko Petroleum Corporation, and EOG Resources participated in the site visit. Representatives from the Ute Indian Tribe, Bureau of Land Management and Utah Division of Oil and Gas, and Mining were also invited to participate in the site visit. At the time of the visit, approximately 7-10 seeps were visible along and bubbling up from within the riverbed. One seep was visible on the cliff approximately 10 feet above the water level. Pools of water with the appearance of motor oil were observed near the seeps. However, there was no visible petroleum sheen or odor near the seeps or within the White River. The black substance found near the seeps behaved consistent with gilsonite; it was granular and did not produce a sheen when disturbed.

2.1.1 Narrative
2.1.2 Response Actions to Date
EPA conducted a preliminary site assessment on July 9, 2014. At the time of the assessment, EPA collected water samples downstream from the seep, at the seep, and upstream from the seep. In addition, a sample of produced water was collected at Anadarko's NBU 456-2E well, located adjacent to the seep. The water samples will be fingerprinted for hydrocarbons and analyzed for a series of water quality characteristics, anions, cations and select metals. Anadarko Petroleum collected samples at adjacent locations.
