North Slope Spills Analysis (NSSA) Reports

The goal of the North Slope Spills Analysis is to reduce the frequency and severity of future spills from North Slope crude oil piping infrastructure integrity loss. The North Slope Spills Analysis represents a continuation of efforts begun in 2008 to conduct the Alaska Risk Assessment (ARA), which was proposed as a quantitative risk assessment of North Slope crude oil infrastructure to consider, among other factors, whether the age of the North Slope oil infrastructure was a significant causal factor contributing to oil spills.
