Title 42 › Chapter CHAPTER 149— - NATIONAL ENERGY POLICY AND PROGRAMS › Subchapter SUBCHAPTER VII— - VEHICLES AND FUELS › Part Part D— - Miscellaneous › § 16104
Requires the EPA to study and help cut long idling by big diesel trucks and locomotives. The EPA must start reviews within 90 days after August 8, 2005 and finish them within 180 days. The reviews check whether EPA’s emissions models show pollution from engines idling more than 15 minutes and whether “idle reduction” technologies actually cut emissions and save fuel. The EPA must update models, rules, and guidance if needed, publish reports, and run a program with the Transportation Department (through SmartWay) to promote idle-reduction and fuel-saving technologies. The law names key terms: Administrator = EPA Administrator; advanced truck stop electrification system = stationary systems that give heat, A/C, power, or communications and can prove use; auxiliary power unit = certified on-vehicle system that provides heat, A/C, engine warming, or electricity; heavy-duty vehicle = diesel vehicle over 8,500 pounds GVWR; idle reduction technology = systems that stop long idling by letting engines be turned off; energy conservation technology = anything that improves fuel economy; long-duration idling = engine running over 15 straight minutes while not in gear (not traffic stops). The law also requires studies of places where trucks stop (truck stops, rest areas, border crossings, ports, transfer points, private terminals) with reports due in 180 days. It authorizes funding for deployment: for heavy-duty vehicles $19,500,000 (FY2006), $30,000,000 (FY2007), $45,000,000 (FY2008); for locomotives $10,000,000 (FY2006), $15,000,000 (FY2007), $20,000,000 (FY2008). At least 50% of project costs must come from non-Federal sources unless the EPA reduces that share. Within 60 days after the first grants are awarded, and every year after, the EPA must report to Congress naming grant recipients, describing projects and funding, and listing all other applicants.
