Narrative
At the time of this release harvest viewed it as related to a pipeline maintenance activity (pigging), and originally believed that the reporting exception in 195.50(b) applied. After discussing this release with the txrrc and reviewing the rulemaking history for the rule, harvest now believes that the intent of the rule is to exempt planned or reasonably expected releases from maintenance activity (for example, releases from a pig trap during pigging). The release in this instance was associated with a pigging activity, but ultimately was caused by internal corrosion on the pipe body. Harvest made a good faith mistake and is filing this report to correct it. There were two accidents that were identified on the pearsall pipeline downstream of dilley station on april 11, 2018. This report is associated with the accident that occurred at shiner ranch. This spill was less than 1bbls and associated cost less than $50,000; therefore, immediate notification to the nrc was not required. On april 11th at approximately 11:02 aerial patrol identified signs of a leak on the pearsall pipeline downstream of dilley station near wilson ranch. The pipeline was shut-in at approximately 11:36 based on this information. While in route to investigate, a harvest operator identified signs of a leak near shiner ranch at approximately 12:20. Preventative measure to keep from reoccurring the in-line inspection (ili) scheduled for 2021 was accelerated to 2018 as a result of a leak that occurred on november 14, 2017. These leaks were identified during progressive cleaning operations in preparation for the ili. The line was shut down and temporary repair clamps were installed on the leak locations. Contaminated soils were removed and progressive cleaning operations continued. The ili was completed april 19, 2018. Based on the 2018 ili data, approximately 8.5 miles of pipe was replaced. The line was placed back into service on august 20, 2018. 3f & 3g: this pipeline was acquired from another operator. The pipe manufacturer and year of manufacture is not known
