Pipeline and Hazardous Materials Safety Administration June 7, 2006 – Federal Register Recent Federal Regulation Documents

PHMSA is closing this rulemaking proceeding, having considered and declined to adopt proposals for further regulating the transportation of flammable liquids in the product piping on cargo tank motor vehicles. On the basis of public comments and additional data and analysis, PHMSA has concluded that further regulation would not produce the level of benefits we originally expected and that the quantifiable benefits of proposed regulatory approaches would not justify the corresponding costs. Although PHMSA is withdrawing its rulemaking proposal, the agency will develop and implement an outreach program to educate the industry, first responder community, and the public about potential risks associated with unprotected product pipelines on these vehicles and will continue to collect data and other information in order to address the issue further if warranted.
