Narrative
On 07/19/17 at 14:17 cst, the alpharetta control center was notified by a colonial inspector of gasoline odors discovered during a pig dig and a request was made to shut the line down. The control center initiated an orderly shutdown of line 1 and remote isolation of the segment starting at 14:20. At approximately 22:50 field observers confirmed the leak. Since it was anticipated that cost would exceed $50,000, the nrc and PHMSA were notified and subsequent courtesy notifications were made to adem, county ema and local fire department. At no time was any free standing product or liquid observed, nor was any lel reading detected during monitoring; only an odor in the soil. Repair was a type b sleeve. Repair was complete at 7/20/17 at approximately 23:48 and line 1 was restarted at approximately 00:17 on 7/21/17. Cause of release still being investigated. As of 7/28/17 the total estimated release volume is 462 gallons. The 462 gallons is contained in approximately 3750 tons of soil which will be removed. A final volume will be calculated once all contaminated soil is removed and all lab results are available. A calculated 38 gallons of product was recovered in 6,655 tons of excavated soil. From excavation dewatering, it was reported that 224 gallons of product was recovered. The total recovery volume for the event was 262 gallons.
