Narrative
A third party inspector working for another pipeline operator noticed a smell of ammonia while working near the magellan ammonia pipeline right of way. He called magellan's operations control center who promptly shut down the line and dispatched local magellan personnel to investigate. Subsequent excavation of the site revealed a leak which was repaired by removing the defective pipe and installing new, pre-tested pipe, and the line was returned to service. The pipe specimen containing the defect was sent to a laboratory for metallurgical analysis which determined the release was the result of a pinhole in external selective seam weld corrosion. The volume of product listed as released in recovered in part a, 9 and 11 is based on the concentration of anhydrous ammonia identified in the excavated soil and volume of soil removed. Approximately 450cubic yards of impacted soil have been remediated to date. Note, the instructions in the most recently issued PHMSA hazardous liquids reporting instructions, page 5 of 13 provides: in cases where an accident results in long-term remediation, an operator may cease filing supplemental reports in the following situations and, instead, file a final report even when additional remediation costs and recovery of released commodity are still occurring: 1. When the accident response consists only of long-term remediation and/or monitoring which is being conducted under the auspices of an authorized governmental agency. 2. When the estimated final costs and volume of commodity recovered can be predicted with a reasonable degree of certainty. Based on that guidance, this supplemental-final report contains estimates in part a, #11 of the total volume of product expected to be ultimately recovered, along with anticipated total costs in part d, #8, in compliance with the provisions of items number 1 and number 2 above. Recovery, which is expected to continue through 2018, has been accepted under the auspices of the kansas department of health and environment (kdhe) voluntary cleanup program which oversees remediation programs of the type represented in this report.
