Narrative
On 09/06/2016 at approximately 11:50 am, a pipeline integrity contractor noticed crude oil leaking on the c18 pipeline. The pinhole was caused by sand blasting during a planned rehab excavation dig as a result of an ili run in 2016, which indicated these were internal corrosion features. A plidco clamp was installed temporarily on 9/6/2016 and the permanent repair by cut-out completed on 09/30/2016. Update: lid c18 has been idled of all hazardous material and is operating under a nitrogen blanket. Idling this line remediates any necessary repairs or analysis due to the absence of hazardous material.
