42 U.S.C. § 16104 — Reduction of engine idling

(a) Definitions. "Administrator" is the EPA Administrator. An "advanced truck stop electrification system" is a stationary system that supplies heat, air conditioning, electricity, or communications to a heavy-duty vehicle and its occupants — with or without using equipment mounted on the vehicle — and that can prove and record that it was used. An "auxiliary power unit" is a combined system, mounted on a heavy-duty vehicle, that supplies heat, air conditioning, engine warming, or electricity, and that the Administrator has certified meets emissions standards under a specific EPA regulation. A "heavy-duty vehicle" is one rated over 8,500 pounds gross weight with a diesel engine. "Idle reduction technology" is an advanced truck stop electrification system, auxiliary power unit, or other technology used to cut long-duration idling by letting the main engine or a refrigeration engine shut off. "Energy conservation technology" is any device, system, or equipment that improves fuel economy. "Long-duration idling" means running the main engine or an auxiliary refrigeration engine for more than 15 straight minutes while the vehicle is not in gear — but it does not include idling caused by ordinary traffic stops or congestion. (b) Idle reduction technology benefits, programs, and studies. (1) Within 90 days of August 8, 2005, the Administrator had to start reviewing whether the EPA's mobile-source emissions models (used under the Clean Air Act) accurately capture emissions from long-duration idling, and update the models as needed; and start reviewing how much idle reduction technology actually cuts emissions, and revise EPA regulations and guidance as needed. (2) Within 180 days of August 8, 2005, the Administrator had to finish both reviews and make one or more public reports on the results. (3) Those reviews and reports could also cover the potential fuel savings from using idle reduction technology. (4) Idle reduction and energy conservation deployment program: Within 90 days of August 8, 2005, the Administrator, working with the Secretary of Transportation, had to use the EPA's SmartWay Transport Partnership to set up a program supporting the rollout of idle reduction and energy conservation technologies, prioritizing deployments based on cost, air-quality benefit, and ability to cut criteria pollutants. Congress authorized, for cutting extended idling from heavy-duty vehicles, $19,500,000 for 2006, $30,000,000 for 2007, and $45,000,000 for 2008; and for cutting extended idling from locomotives, $10,000,000 for 2006, $15,000,000 for 2007, and $20,000,000 for 2008. At least 50% of each project's direct costs must come from non-federal sources, though the Administrator can lower that requirement if needed to meet the program's goals. (5) Idling location study: Within 90 days of August 8, 2005, the Administrator, with the Secretary of Transportation, had to start a study of everywhere heavy-duty vehicles idle for long periods — truck stops, rest areas, border crossings, ports, transfer facilities, and private terminals. Within 180 days of August 8, 2005, the Administrator had to finish the study and publish one or more public reports on it. (c) Omitted. This subsection has been left out of the current text (it was removed or reclassified elsewhere). (d) Report. Within 60 days after the first grant funds go out under this section, and every year after that, the Administrator must report to Congress: who got grants, what projects the money funds, and how much funding each got; and who else applied but didn't get funded.
