PHMSA Promptly Addresses Engine Requirment for MBT Loading and Unloading Operations
Following an alert from IME, PHMSA has promptly updated all multi-purpose bulk truck special permits to waive the requirement at 49 CFR 177.835(a) that vehicles loading or unloading explosives must be stopped. Affected special permits have been changed, effective February 28, 2013, to allow engines to run if necessary for the operation of a pump, auger, or other equipment to load or unload materials from the vehicle. The change can be found in the "Special Provisions" section. All affected special permit holders should receive updated copies of these documents.
