National Aeronautics and Space Administration for the systems analysis work are uncertain beyond fiscal year 1996. The committee was also concerned that the U.S. Department of Transportation is not playing an active role in addressing and resolving PNGV transportation policy and safety issues and that the U.S. Environmental Protection Agency does not appear to be addressing the question of emissions standards for new PNGV technologies. The U.S. Department of Defense also needs to be more supportive and involved in the PNGV research program.
To be successful, a complex development program such as the PNGV must have well-defined plans and objectives, adequate resources, and sufficient funding support. Although significant progress has been made, in the committee's view, it is incumbent upon both USCAR and the government to ensure that adequate resources for the PNGV program are provided in a timely manner and used efficiently in overcoming the critical barriers to achieving PNGV goals.
