On 09/09/16 at 11:10 cst the colonial pipeline control center was notified of a suspected leak in shelby county, al (approximately 9 miles upstream of pelham station). The control center reported shutdown and remote isolation of the segment at 11:30. At 11:20 local row personnel were dispatched to investigate. At 12:14 field observers confirmed a release of gasoline. Nrc was notified at 12:59 via report #1158584. Adem, county ema and local fire departments were subsequently notified and a unified command system structure was implemented.

The report stated that "a wrinkle occurred in the pipe extending approximately 180 degrees from the 9 o'clock to 3 o'clock position. A circumferential crack of approximately 1-1.5 inches was present at approximately the 12 o'clock position at the wrinkle path. The wrinkle was caused by "inadequate soil consolidation under line 01 following maintenance/recoat activities in 2015." update 2/14/18: soil mass balance for the cr91 release was calculated using landfill weight tickets and an average of the tph gro from stockpile samples. The tph gro average was 278.5 mg/kg and the soil weight was 13942 tons. Using the worksheet, total volume of product in soil was calculated to be 1,275 gallons. All soil was disposed of at a landfill with disposal approval by adem. Any future, long-term remediation will be conducted under the guidnace of adem.
