Action
Advance notice of proposed rulemaking and notice of public meeting.
Summary
In this advance notice of proposed rulemaking, RSPA requests comments concerning the need, if any, for amending the Hazardous Materials Regulations with regard to emergency discharge control features required on cargo tank motor vehicles in liquefied compressed gas service; the ability of industry to meet a possible 1-, 2- or 3- year retrofit schedule; standards for the qualification, testing and use of hoses used in unloading; safety procedures for persons performing unloading operations; and, whether the Federal government should continue to regulate in this area. This advance notice of proposed rulemaking addresses specification MC 330, MC 331, and certain non-specification cargo tank motor vehicles which are used to deliver propane, anhydrous ammonia, and other liquefied compressed gases. It responds to recently discovered deficiencies which affect the safety of unloading liquefied compressed gases from many of these cargo tank motor vehicles. The intended effect of this action is to obtain information concerning the need for regulatory changes to ensure an acceptable level of safety for delivery of liquefied compressed gases, the costs and benefits associated with such changes, and ways to minimize impacts on small entities affected by them. RSPA also is announcing a public meeting to solicit comments on issues identified in this docket.
