I am anything BUT a tree hugger....in fact most of my investments are in the oil and gas. By beef with Enbridge....is that they seem to operate irresponsibly based on the incident....they knew corrosion was an issue and did not follow through.
Pipeline integrity mgmt. is just good business - mitigation of risk is good for the bottom line. Why were not embedded detectors to detect spills in critical areas. They now jeopardize their Northern Gateway project.
BP is another bad actor....pervasive culture on poor safety and reliability. We all know what happened.
The impacts are twofold: Remediation costs + fines and increased capital costs and regulations on future projects.
