PART H - NARRATIVE DESCRIPTION OF THE ACCIDENT
On 8/14/2020 at 18:20, a Colonial employee was notified by a local resident about a possible leak in Colonial's Right-of-way (ROW) approximately 100 feet
north (i.e., downstream) of Huntersville-Concord Road in Huntersville, NC. The possible leak location was discovered by utility vehicle riders that were on
a trail that crosses the pipeline ROW. The Colonial employee lives in the area and went to inspect the location. Upon inspection, the Colonial employee
confirmed a product release visible at the ground surface at 18:42 near mile marker 980 that was believed to be gasoline. The Colonial employee
contacted the Colonial Control Center in Alpharetta, GA to provide notification of the visible release and the Control Center initiated shutdown of Lines 1
and 2 at 18:43. The lines were blocked by closing valves upstream of the release location at Colonial's Charlotte Delivery facility (DF) and downstream of
the release location at the Kannapolis Station. The Colonial Operations Manager (OM) was notified at 18:44, and the Director of Operations (DO) was
notified at 19:00, followed by additional internal notifications that were made to mobilize resources to address the conditions discovered. At 19:42, a NRC
notification was made by the Control Center (Report number 1284598), the initial volume was reported at 75 barrels (bbls.), based on the limited
information Colonial had at the time. Notifications were also made to Mecklenburg County, US EPA, NCDEQ, and PHMSA. The NRC notification was
updated on 8/16/2020 at 17:40, with an estimated release volume of 1500 bbls. based on additional information available to Colonial as a result of the initial
response efforts.
Colonial issued an internal Tier 2 response notification at 19:32 to mobilize internal and contractor resources to the site, and established an Incident
Command Post to support the response. The leak source was identified on 8/15/2020 at approximately 12:00. Following confirmation of the leak source
being on Line 1, Line 2 was authorized to restart on 8/15/2020 at 0:05. The leak source was originating from beneath a prior repair (Type A sleeve) made in
2004 to address a pipeline anomaly identified through a previous integrity assessment. The leak was repaired by installing a Type B pressure containing
sleeve over the prior Type A sleeve repair. Line 1 was restarted on 8/19/2020 at approximately 21:00 after repair were completed.
The continued recovery of product and completion of the site characterization will have oversight by the North Carolina Department of Environmental
Quality (NCDEQ) and Mecklenburg County.
