3.5.5.5 Impact Analysis
Residual Impacts
Following mitigation, the residual risks during all project periods are in the Low
category and within international standards to minimize risk to downstream
public and environmental resources.
Prediction Confidence
The estimation of risk in the reference report (Pipeline Systems Incorporated,
2005) accounts for the variation in data and prediction confidence as described in
Section 3.5.5.4. However, risk ratings are also dependent on the success of the
mitigations proposed, including those listed in Section 3.5.5.3. Overall, the
prediction confidence for this assessment is considered Medium.
Monitoring
Monitoring programs were summarized in Section 3.5.5.3 for the leak detection
system and pipeline route inspection and maintenance program.
3.5.5.6 Conclusions
Following mitigation, increased risks of natural hazards to the public and
environment as a result of the pipeline are estimated to be low and within
international standards.
