Narrative
On august 7, 2010 a 26' natural gas transmission pipeline operating at approximately 375 pounds was damaged by a farmer performing grading work. While grading fields, the farmer struck and damaged the main. No injuries or public property damage resulted from this incident. All repairs have been completed, and pipeline has been put back into service. Investigation of the incident showed that the excavator did not have a USA ticket, but was aware of piping from a previous locate request performed years ago. This incident was reported to PHMSA under incident # 95266, based upon damage to company facilities exceeding $50k. Note: damage amount and gas lost costs are off by a factor of 10x stated value. Form would not accept 6 fgure numbers. Discussed with peter katchmar, agreed we will submit this original and submit a revised final when issue resolved.
