Narrative
On august 8, 2017 at approximately 13:20 operator personnel were onsite preparing to install a cathodic protection test lead on the talpa to zephyr segment of the amdel pipeline system and discovered some staining on the surface of the row. Personnel immediately contacted the control center and the line was shutdown at approximately 13:30. The area of the staining was excavated and it was determined that the release was immenating from the cased crossing of a state road. The casing was cut back and a pinhole at the 6 o'clock position of the pipe was discovered. A clamp was installed to prevent further release of product. The casing spacer system had failed in this area allowing the pipe to contact the bottom of the casing which caused deterioration of the coal tar coating. Ili data for this casing was reviewed and it was determined that the entire crossing would be replaced with heavy wall pipe eliminating the cased crossing. Ili data for other crossings in this segment were reviewed as well and no other repairs were determined to be necessary at this time. All free product was recovered and contaminated soil was remediated on site. Subsequent to the crossing being replaced the pipeline was restarted on august 12, 2017.
