Crude-By-Rail Safety Act
This bill directs the Department of Transportation (DOT) to:
establish, by regulation, an interim national standard for the maximum volatility (measured by the vapor pressure) of crude oil transported by rail within the United States;
Showing the opening paragraphs of the official summary.
study the best methods for reliably measuring that volatility as well as the level of volatility consistent with the safest practicable shipment of crude oil by rail;
issue a final rule establishing the maximum volatility of crude oil transported by rail; and
issue also a final rule, based on specified safety standards, which requires that all new tank cars designed to transport a Class 3 flammable liquid meet or exceed the design standards set forth in a related Notice of Proposed Rulemaking.
DOT shall prohibit immediately the shipment of oil or ethanol in: (1) any DOT-111 tank car that does not meet the requirements of Casualty Prevention Circular 1232, issued by the Association of American Railroads on August 31, 2011; or (2) any unjacketed CPC-1232 tank car. Tank cars retrofitted to meet or exceed certain design standards may, however, continue to transport oil or ethanol, but they must also be equipped with electronically controlled pneumatic brakes.
Rail carriers must perform at least two additional internal rail inspections per calendar year than required by specified law as well as at least four track geometry inspections on routes that: (1) the rail carrier owns or has been assigned maintenance responsibility, and (2) over which one or more high-hazard flammable trains are operated.
Any person offering oil for transportation shall complete spot inspections on 5% of all individual rail cars loaded with crude oil to:
test and record the volatility of the crude oil in the cars, and
ensure that the crude oil meets the interim national standard for maximum volatility established under this Act or any more restrictive volatility standard subsequently enacted.
DOT shall also complete spot inspections on crude oil volatility to ensure that volatility standards are being met.
Knowing violators of hazardous materials transportation law, of energy product inspections, and of rail inspections shall be subject to specified civil penalties.
DOT shall:
establish or expand safety programs relating to the transportation of energy products and other Class 3 flammable liquids by rail, pipeline, highway, and waterway; and
publish a final rule revising certain oil spill prevention and response plan regulations to include specified requirements.
No rail carrier may operate any high-hazard flammable train in any state until it has given specified information, including emergency response and contact information, to the Emergency Response Commission for that state and any local emergency planning committee along the route the train will operate.
Rail carriers must collaborate to develop an inventory of emergency response resources along routes over which one or more high-hazard flammable trains operate for responding to worst case discharges resulting from accidents involving unit trains or blocks of tank cars transporting Class 3 flammable liquids.
DOT shall:
promulgate requirements for a railroad carrier to follow in establishing a confidential close call reporting system program meeting specified criteria,
contract with the Transportation Research Board of the National Academy of Sciences to study high-hazard flammable train liability, and
conduct a comprehensive review of existing regulations for energy products transported by all modes of transportation.
