The Vehicular Alternative Fuel Systems technical committee has been working on a complete reorganization of NFPA 52, the Vehicular Gaseous Fuel Systems Code. This code covers both compressed and liquid natural gas fueled vehicles. These vehicles have seen increased use over the past several years, particularly in fleet usage. Natural gas is a clean burning fuel, creating less carbon dioxide emissions than gasoline or diesel. The new edition, just finishing up second draft now, will be simpler and easier for the user, grouping material common to both fuels together, and then listing supplemental requirements for each fuel. The new edition will be published in 2016.
