Title 42 › Chapter 149— NATIONAL ENERGY POLICY AND PROGRAMS › Subchapter VII— VEHICLES AND FUELS › Part D— Miscellaneous › § 16104
EPA must study and act to cut long engine idling by heavy-duty diesel vehicles and help put idling-reduction equipment into use. Key words used in the work are defined briefly: Administrator — the head of the Environmental Protection Agency; advanced truck stop electrification system — a stationary system that gives heat, air conditioning, electricity, or communications to a heavy truck and can show it was used; auxiliary power unit — a built-in system that provides heat, air conditioning, engine warming, or electricity and is certified under EPA rules; heavy-duty vehicle — a diesel vehicle rated over 8,500 pounds; idle reduction technology — systems (including the two above) that stop long idling and let the main or refrigeration engine be turned off; energy conservation technology — anything that improves fuel economy; long-duration idling — running a main or refrigeration engine for more than 15 straight minutes while not in gear (does not include normal traffic stops). Within 90 days after August 8, 2005, EPA must start reviewing its vehicle emissions models and study how well idling-reduction technologies cut emissions. EPA must update models, regulations, and guidance as needed, and finish reviews and publish reports within 180 days. EPA, working with the Transportation Department through the SmartWay program, must set up a program to deploy idle-reduction and fuel-saving tech, giving priority to cost-effective projects that improve air quality. Authorized funding to carry out the program is $19,500,000 (FY2006), $30,000,000 (FY2007), and $45,000,000 (FY2008) for heavy-duty vehicles, and $10,000,000 (FY2006), $15,000,000 (FY2007), and $20,000,000 (FY2008) for locomotives. Projects must normally cover at least 50% of costs from non-Federal sources, but EPA may lower that share if needed. EPA must also study places where heavy trucks stop (for example, truck stops, rest areas, border crossings, ports, transfer points, and private terminals) and report results within 180 days. Within 60 days after funds are first awarded, and each year after, EPA must report to Congress who got grants, what projects were funded and how much, and who applied.
