Hazardous Materials: Oil Spill Response Plans for High-Hazard Flammable Trains

Summary: PMHSA is issuing this ANPRM in conjunction with a notice of proposed rulemaking (NPRM)--Hazardous Materials: Enhanced Tank Car Standards and Operational Controls for High-Hazard Flammable Trains (2137-AE91), which PHMSA is also publishing today. In this ANPRM, PHMSA, in consultation with the Federal Railroad Administration (FRA), seeks comment on potential revisions to its regulations that would expand the applicability of comprehensive oil spill response plans (OSRPs) to high-hazard flammable trains (HHFTs) based on thresholds of crude oil that apply to an entire train consist.
