Transit will be a critical part in reducing diesel particulates in ozone and in reducing greenhouse gas emissions. We need clean fuel transit to make the Clean Air Act work and to make AB32 work. The biggest health problem in ozone now seems to be diesel particulates. They cause heart and lung problems and different kinds of cancers, as well as misscarriages in pregnant women. The closer a person lives to a major roadway, the more likely they will have health problems. Diesel engines in the bus fleets should be replaced with clean hydrogen fuel or all-electric power. Solar energy can be used at the bus yard to produce the hydrogen and/or recharge electric batteries on all-electric powered buses.Another source of diesel particulates and a health concern for people living close to trainyards is the diesel particulates from locomotives and yard operations. Burlington Northern Santa Fe has put the first all hydrogen power locomotive in service in its giant Los Angeles yard. There needs to be more of this type of technology and it needs to be improved so it can be used for short haul local freight movement and long haul transcontinental freight movement. Best wishes, Michael E. Bailey.
