Hazardous Materials: Miscellaneous Petitions for Rulemaking (RRR)

Notice of proposed rulemaking (NPRM).

In response to petitions for rulemaking submitted by the regulated community, PHMSA proposes to amend the Hazardous Materials Regulations (HMR; 49 CFR parts 171 through 180) to update, clarify, or provide relief from miscellaneous regulatory requirements. Specifically, PHMSA is proposing amendments that include, but are not limited to, the following: Incorporating by Reference (IBR) multiple publications from both the Compressed Gas Association (CGA) and the Chlorine Institute; addressing inconsistencies with domestic and international labels and placards; permitting alternative testing for aerosols; no longer mandating that excepted quantities comply with the emergency response telephone requirement; allowing electronic signatures for Environmental Protection Agency (EPA) manifest forms; and no longer requiring the service pressure to be marked on Department of Transportation (DOT) 8 and 8L cylinders.
