Public release of details about oil-train routes and shipments does not pose a serious security risk, the federal government said yesterday.

Earlier this month, I wrote about how the Department of Transportation issued an emergency order requiring railroads to tell states about shipments within their borders of the more-explosive-than-usual Bakken crude, so that those states and relevant municipalities could prepare for the Lac-Mégantic-sized explosions that might be lying in store for them.

Railroads said, “Yeah, sure,” and then turned around and drew up non-disclosure agreements (NDAs) for every state they were routing oil through. By the conditions of the NDAs, the states could only use the crude shipment information for disaster planning and response. Any other disclosure and it was lawsuit time.
