This attachment shows an image of the design and fabrication details, including dimensions, for the General Service symbol plaques D9-11xP (1 of 2) for four of the alternative fuels in the Alternative Fuels Program: Hydrogen (HYD), Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas (LPG). The General Service symbol sign for each has a blue background with white legend and border. The legend on these signs are comprised of a white colored image of a symbolic gas pump, including hose and nozzle, with the letters "HYD", "CNG", "LNG", and "LPG" aligned vertically in the middle of the pump symbol for each of the different plaques configurations. The first letter of the three letters representing each of the fuel types is always on top with the last letter of the three fuel types on the bottom.
