Clean Air Program : Design Guidelines for Bus Transit Systems Using Alcohol Fuel (Methanol and Ethanol) as an Alternative Fuel

Although there are over one thousand transit buses in revenue service in the U.S. that are powered by alternative fuels, there are no comprehensive guidelines for the safe design and operation of alternative fuel facilities and vehicles for transit systems to follow in either retrofit or new facility design. This document addresses that need. The purpose of the document is to provide guidance, information on safe industry practices, applicable national codes and standards, and reference data which the transit agencies should review when considering modifications to their existing facilities or when planning new bus facilities to safely use an alcohol fuel as an alternative fuel. Fueling facility, garaging facility, and maintenance facility requirements and safety practices are presented
