Narrative
On september 9, 2010 at approximately 12:28 cdt, the edmonton control center received a call from the romeoville fire department stating that crude oil was visible on the ground near 719 parkwood avenue in romeoville il. The control center shut down lines 6a, 14, 13, and 61 in order to investigate the source of the leak. Enbridge staff was immediately dispatched to the area. Oil from the release migrated into near-by storm water and septic sewer systems, and reached both a local storm water retention pond and water treatment plant. Local emergency officials, epa, ntsb and PHMSA responded to the incident and were onsite during the excavation, repair and line-fill of line 6a. Due to the proximity of this leak to a number of local businesses, romeoville emergency response officials advised approximately 470 people to vacate the area during the initial phases of the response to facilitate site access and containment efforts. Enbridge estimates that it will incur aggregate charges between $40 and $60 million exclusive of fines and penalties. These charges include emergency response, environmental remediation, containment and cleanup activities associated with the crude oil release, costs to repair the pipeline and related inspection costs, potential claims by third parties and lost revenue. We continue to work to accurately project the total cost of the leak and its remediation, however we are unable to break it down into the specific detail requested in this form due to the complexity of the efforts. Under the direction of the ntsb, the failed section of pipe and the water line that was within close proximity have been sent to a laboratory for metallurgical analysis. Pending the results of the metallurgical testing and failure investigation, enbridge is unable to provide complete and final data regarding cause for this original report submission. Volume of crude oil released from the pipeline has been revised to the following estimates: 7,538 barrels, with 7,538 recovered and 1,131 barrels reaching an unnamed drain and retention pond. The 7,538 bbls is the esimated amount recovered in tankage and may not include additional oil recovered in waste streams. Enbridge continues to work through the site remediation program with the illinois environmental protection agency (iepa). The remedial objectives report (ror)/response action plan (rap) was approved by the iepa and the rap has been implemented at the site. The enbridge environment group meets annually with the iepa to discuss the project direction. Ground water and surface water will continue to be monitored for a couple more years. Since the initial release, there have not been any detections above criteria in either the ground or surface water. We are currently monitoring a network of 30 monitoring wells and 5 surface water locations on a combined quarterly and annual basis. Approximately 15,049 tons of contaminated soil was excavated and disposed off-site. Site closure was received from the iepa on august 12, 2013. The national transportation safety board determined that the probable cause of the release was erosion caused by water jet impingement from a leaking 6-inch diameter water pipe 5 inches below our pipeline. Contributing to the accident was the interruption of the cathodic protection currents by the close proximity of the improperly installed water pipe.
