## Abstract

On January 25, 2011, FRA published a Federal Register document stating that markings on tank cars related to certain gross weight on rail (GRL) Special Permits that had been incorporated into the hazardous materials regulations (HMR) by a Pipeline and Hazardous Materials Safety Administration (PHMSA) rulemaking were required to be removed or obliterated by January 25, 2012, or at each subject tank car's first shopping event, whichever occurred first. This document relieves tank car owners from that previously stated deadline and extends the time for removal of the markings until the date of each subject tank car's next required qualification.
