The City Staff released Extraction’s long-awaited Pipeline Risk Analysis today. It is the result of Best Management Practice (BMP) 3 in Exhibit B of the Operator Agreement which reads, “If requested by the City, Operator will conduct a risk analysis to identify potential risks associated with pipelines and the measures implemented that are intended to mitigate such risks.”
The City requested this Pipeline Risk Analysis from Extraction on September 10, 2018. In early January 2019, the City reported that Extraction would have the report available to the City by February 22, 2019. Pipeline construction began in November 2018 as shown on the City’s map below and there has been extensive destruction of Nordstrom Open Space during pipeline construction.
Extraction’s document states that it “summarizes the risk analysis process and evaluated risks, mitigation, and contingency plans” for pipelines “to transport crude oil, associated field gas, and produced water from production wells and central distribution points.” Extraction’s affiliate Elevation Midstream, LLC is currently constructing and will operate the pipelines.
Risk categories identified for pipeline operations in the document include:
Release of Gases
Surface Water Pollution
Corrosion Leading to Material Loss
Mechanical Failure Leading to Material Loss
Human Error/Miscommunication Leading to Material Loss
Faulty Design, Construction, or Repair
IT Systems Failure Leading to Material Loss
Table 3-1 also lists mitigation measures. There does not appear to be any quantified analysis of these risks.
