RSPA Proposes Changes to Rules Governing Cargo Tank Unloading

摘要

Changes to the rules governing cargo tank unloading operations for liquefied compressed gases have been proposed by the Department of Transportation's Research and Special Programs Administration (RSPA). The notice of proposed rulemaking on the revisions was published in the Federal Register March 22,1999. Among the new provisions is one that modifies earlier proposals to require an attendant to have an uninterrupted view of the hose from the MC330-MC331 vehicle to the storage tank. It would have applied to LPG and anhydrous ammonia distribution in particular. The new proposal takes into account some of the delivery requirements involving the products while assuring that the person attending the unloading operation can quickly determine if an unintentional release occurs. Concern had been voiced in the delivery of propane to tanks that would require the driver to be out of sight of the truck.
