July has been a tough month for Enbridge's
Oil, oil everywhere
Earlier this month, the National Transportation Safety Board completed its review of the 2010 Enbridge pipeline spill in Michigan, and the findings are not pretty.
The NTSB report criticized both Enbridge and the Pipeline and Hazardous Materials Safety Administration for negligence and weak oversight. Apparently, weakness in the pipeline was detected as early as 2004, and no one did anything about it. When the line finally ruptured in 2010, the ensuing actions of Enbridge employees pointed to a disturbing lack of preparedness.
Critics are quick to point to the Kalamazoo incident when considering the likelihood of another Enbridge spill. And why not? As a pipeline operator, you have essentially two responsibilities to the general public: maintain the integrity of the line and respond appropriately in the event of a spill. Enbridge failed miserably on both counts, establishing a precedent that will be difficult to dismantle in the minds of Americans and Canadians alike.
Opposition to Enbridge's premier project, the Northern Gateway pipeline, has skyrocketed. A former insurance executive has called into question Enbridge's insurance policy for the Northern Gateway, strongly suggesting the company should be required to buy additional insurance if the project is approved. After reading the NTSB report, some politicians in Canada are calling for the outright rejection of the Northern Gateway pipeline. Citizens have been up in arms about the project for quite some time, and their numbers are only growing.
When to say "when"
The growing hostility is a headache for Enbridge, but the market, for all intents and purposes, does not care about pipeline spills or the NTSB report. In fact, over the course of the past two years, Enbridge shares have handily beaten the performance of the S&P 500:

As you can see, outside of a June 2011 stock-split anomaly, shares have slowly trended up over the past two years, more or less mimicking market hiccups and resulting in an 80% return for investors.
The question now becomes: If the market isn't going to punish a company for its negligence, is selling in the face of mounting opposition to any and all Enbridge projects an overreaction? Do investors continue to hold this stock?
Let's do some math
Looking at the numbers might help. The Michigan spill cost Enbridge $765 million. The company only paid $115 million out of pocket, though, because insurance covered $650 million. The company may well face the highest fine ever issued by the Pipeline and Hazardous Materials Safety Administration, but that's still only $3.7 million -- a figure similar to what the company paid for its Northern Gateway advertising campaign. In the grand scheme of things, this costly disaster simply didn't cost very much, which may explain in part why the market has not reacted.
There is no guarantee that will always be the case, however. There is a clamor for greater government oversight, stiffer penalties, and increased accountability from pipeline operators, which may increase fines and the general cost of doing business in the future.
Already, the expense of the Northern Gateway project has grown from $5.5 billion to $6 billion as Enbridge has promised to use "extra-thick" pipe where the route crosses water.
Wait and see
The factors behind the Kalamazoo River spill should serve as a giant red flag to investors. At the same time, it is hard to dismiss a company that is single-handedly responsible for the transportation of 13% of the U.S.'s total oil imports. I encourage investors on the fence to remain there while we see what kind of ship new CEO Al Monaco will run.
In the meantime, keep an eye on how Enbridge works to implement growth across its network. The company recently reversed the Seaway Pipeline that it co-owns with Enterprise Products Partners
Foolish takeaway
Enbridge isn't the only pipeline company facing opposition, and as we take a close look at this company, we should consider the industry at large. Plains All American
