Following the Exxon Valdez disaster in Alaska, Congress passed the Oil Pollution Act. It required that all new oil tankers have double hull construction and all single-hull tankers were to be phased out of operation in 25 years. The 25 years will be up in 2015.
We may see something similar as a result of Lac Megantic. Since October 1, 2011 DOT has required all new tank cars for transporting ethanol or crude oil to have
–Increase head and shell thickness
–Normalized steel
–½-inch thick head shield
–Top fitting protection

As a result of Lac Megantic, regulators may require phase-out or retrofit of existing tank cars over some period of time. We may even see the Canadians take the lead on regulating the North American rail fleet in this case.
Meanwhile, there are normal maintenance issues that need to be addressed.
And in North Dakota alone, there are some 2,500-3,000 bad order tank cars per month. Clearly North Dakota is a hotspot for maintenance since that’s where a majority of the new cars are operating and/or headed. And because it’s such a new phenomenon, North Dakota has not been a hot spot for maintenance until now.
