PHMSA Withdraws Flammable Liquids Wetlines Proposal

Posted on 12/30/2015 by Roger Marks

In the Federal Register today, the US DOT Pipeline and Hazardous Materials Safety Administration (PHMSA) officially withdrew its proposed rulemaking to prohibit flammable liquids in external product piping on DOT specification cargo tank motor vehicles (CTMV) in transportation.  When carrying product, the lines or hoses used to load or unload a CTMV are called “wetlines.” If not protected, wetlines may be exposed to a collision in transport.

Congress ordered PHMSA to withdraw the proposed wetlines rule in the five year, $305 billion Fixing America’s Surface Transportation Act, or FAST Act.  See the other hazmat shipping items in the FAST Act here. 

A rule to regulate flammable liquids carried in the piping of cargo vehicles has been part of US DOT’s hazmat rulemaking agenda for a number of years—it was originally proposed in 2011, and was named one of the Hazmat Final Rules to Watch for in 2016 before Congress ordered PHMSA to withdraw it.
