Narrative
On 10/25/2020 at approximately 4:00pm, operations discovered a seep coming from a thermal line on the discharge side of the mainline pump. The line was isolated, drained and repaired. It was estimated that 36.61 gallons of product was released and a majority captured by secondary containment. The release stayed onsite. No injuries or property damage was reported. The affected soil will be drummed up and properly disposed of. It was found that two 3/4" nipples cracked and have been sent for lab analysis. The cause is still under investigation. Update 3/31/21: failure was due to mechanical fatigue cracking initiating in the pipe thread root in both samples. The source of the cyclic loading driving the fatigue is unknown.
