1.1.1 Incident Category
On 1 December 2014, a spill of crude oil from the Cobb et al B-1 well, Serial #97981, located at 10165 Masters Rd, in Mooringsport, Louisiana, was reported by the Louisiana Department of Natural Resources (LDNR). The Cobb et al B-1 well is considered abandoned/orphaned by the LDNR. Although the total volume of oil discharged is unknown, initial EPA estimates are approximately 30 barrels (bbls). The oil discharged onto surrounding soil and vegetation, before flowing directly into an adjacent creek east of the Cobb et al B-1 well.
1.1.2 Site Description
The spill origin is located adjacent to an above ground high voltage transmission line right of way in Mooringsport, LA , Latitude: 32.52975067° North, Longitude 94.036338759° West. After entering a creek adjacent to the spill origin, crude oil flowed downstream to the south-southeast. The initial spill pathway distance between the origin and the most downstream impacted area is approximately 0.3 miles. The stream distance between the spill origin and the most downstream containment, located at the Alexander B1 well, Serial #93964, is approximately 0.7 miles.
1.1.2.1 Location
The Site is located in Mooringsport, LA , Latitude: 32.52975067° North, Longitude 94.036338759° West.
1.1.2.2 Description of Threat
Crude oil impacted soil, vegetation, and water between the spill origin and a fork in a tributary that flows into the Paw Paw Bayou, located at Latitude: 32.526228° North, 94.033673° West.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
On 2 December 2014 at 1504, On-Scene Coordinator (OSC) Mike McAteer activated the Superfund Technical Assessment and Response Team (START) and Emergency and Rapid Response Services (ERRS) contractors.
The EPA Team (OSC, START, and ERRS) arrived onsite at approximately 0900 on 3 December 2014. The EPA Team performed an initial assessment of the well site and spill area.
During the initial assessment, crude oil was observed actively purging from a pinhole leak on the well, discharging onto the surrounding ground before entering the adjacent creek. ERRS was directed to begin clearing a path to the creek, begin initial debris removal and boom placement in the bayou. START tracked the spill pathway, and estimated 0.3 miles of creek was impacted. The LDNR representative asked for assistance from a local well drilling company in order to repair the leak. One live oiled snake (water moccassin) was observed on the bank of the creek. No other impacts to wildlife were initially observed.
The initial recovery team consisted of five (5) ERRS crew members and one vacuum truck.

2.1.1 Narrative
2.1.2 Response Actions to Date
On 3 December 2014, START tracked the spill pathway, and the distance of impacted creek is an estimated 0.3 miles. ERRS placed boom (hard and absorbent) in the creek to contain the oil and prevent any farther downstream impact. Boom was placed at the farthest point downstream where no further oil was observed. ERRS used absorbent pads to remove oil from the creek and initiated oil contaminated debris removal from the creek.
On 4 December 2014, an additional four (4) ERRS crew members and one (1) ERRS Response Manager (RM) arrived, increasing the recovery team to a total of 1 RM, 1 foreman and 8 laborers. Pooled crude oil near the wellhead was collected utilizing the vacuum truck. Oily debris continued to be manually collected from the creek and placed into poly bags for disposal. Approximately 750 gallons of crude oil and 153 bags of oil debris were collected. An excavator, two 20 cubic yard (yd3) roll-off containers, additional absorbent supplies, and the EPA’s Logistics Response Vehicle (LRV-2) arrived onsite to support the incident. Earthen berms between the spill origin and the creek were constructed to prevent additional discharges to the creek in anticipation of forecasted rain events.
On 5 December 2014, excavation of visibly impacted soils around the spill origin was conducted and stockpiled onsite for future disposal. A sample of the stockpile was collected by ERRS and submitted for analysis to characterize the impacted soil. Debris removal and placement of absorbent pads in the creek continued.
On 6 December 2014, excavation activities continued starting at the wellhead and working down gradient. ERRS utilized absorbent pads to wipe crude oil from the pumping unit, and continued debris removal and placement of absorbent pads in the creek.
EPA and START conducted reconnaissance along the creek to ensure oil did not migrate farther than the most downstream containment located at the Alexander B1 well. In addition, an assessment of the Paw Paw Bayou was conducted where it intersects Louisiana Hwy 169 and where the bayou enters Cross Lake. No crude oil or sheen was observed at either area.
On December 7 2014, recovery efforts were focused at the most downstream impacted area, removing pooled crude oil via vacuum truck and manually removing oiled debris. An additional reconnaissance of the spill pathway was conducted by the OSC and START to plan for additional cleanup activities, and to prepare for closeout operations.
To date, a total of 618 bags of oiled debris and approximately 2,250 gallons of oil have been recovered.
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
The last known lease owner is The Hardey Company of Vivian, LA (owner: Robin Hardey). On 5 December 2014, Mr. Hardey was contacted by telephone, and a Notice of Federal Interest (NOFI) letter was issued.
