Washington D.C. The U.S. Department of Transportation announced last week that it will raise safety standards for transporting volatile liquids across U.S. rail lines. New standards will be introduced for tank cars, brakes, shipment testing and speed limits for trains carrying flammable liquids including oil and ethanol. The new rules would also require railroads and shippers to notify State Emergency Response Commissions or other appropriate state delegated entities about the operation of trains carrying 1,000,000 gallons or more of Bakken crude oil through their states. The proposed regulations would also phase out the use of older DOT-111 cars within two years unless they are retrofitted to comply with new design standards.
