At the April AAR TCC meeting, the FRA reminded everyone of certain Class 3 flammable liquid commodities (such as ethanol) and the phase out of DOT 111 non-jacketed CPC-1232 tank cars by July 1, 2023. PHMSA defined ethanol as: UN1170, NA1987, UN1987, or UN3475.
No loaded tank car may be offered into transportation and the FRA will not grant an OTMA for a loaded tank car. Residue tank cars will only be allowed to move with an OTMA from the FRA or Temporary Certificate from TC.
