Narrative
On 5/23/2016, at approximately 1235 hrs, chaparral received notification from its contractor stating there were indications of a possible CO2 leak on the coffeyville CO2 pipeline. The contractor had been performing maintenance activities on row line markers when he observed rain puddles in the row with bubbles emanating from the surface. At approximately 1310 hrs on 5/23/2016, the pipeline supervisor verified the location of the indications. The release did not result in explosion, fire, death, personal injury, significant property damage, or pollution of any water body, and the release was confined to the pipeline right of way. The CO2 source plant was notified and shutdown, the leak segment was isolated, and emergency onecalls were made to later excavate the pipe. The isolated segment was blown down at mlv 12 and mlv 13. On 5/24/2016, pipeline excavation began and dry ice was soon found underground along the pipe. The leak location was located and verified on 5/25/2016 at approximately 1910 hrs. Upon excavation, the coating was found to be damaged in the vicinity of the leak, on the girth weld. On 5/26/2016, the portion of the pipe containing the leak and weld was cutout and removed, and was replaced with pre-tested pipe. X-ray of both welds was accepted. Welds were doped, and the pipeline was purged with CO2 by opening the upstream valve. Once purging was completed, valves were opened and the CO2 source plant was restarted to return the pipeline to normal pressure. That normal pressure on the pipeline was held for 2 days, without flowing product to the customer, while a ground patrol was conducted between mlv10 and mlv14 with no indications of any further releases. After returning the pipeline to regular service in a safe manner, we conducted an inline inspection of the entire pipeline. The affected segment of pipe was sent to a testing laboratory for further analysis.
