Title 42 › CHAPTER 149 — NATIONAL ENERGY POLICY AND PROGRAMS › SUBCHAPTER VII — VEHICLES AND FUELS › Part C — Clean School Buses › § 16091a
Creates a competitive grant program at the Environmental Protection Agency to help buy, retrofit, or fuel heavy school buses so they pollute less. Eligible recipients include local or State school bus authorities, companies that run school bus service, and nonprofit school-transportation groups. The EPA Administrator, working with the Energy Secretary, will run the program. Key definitions: Administrator = EPA Administrator; Secretary = Energy Secretary; alternative fuel = liquefied natural gas, compressed natural gas, liquefied petroleum gas, hydrogen, propane, methanol or ethanol at 85% or more, or certain biodiesel (ASTM standard as of August 10, 2005); clean school bus = bus over 14,000 pounds with a heavy-duty engine that runs only on an alternative fuel or ultra-low sulfur diesel; retrofit technology = verified particulate filter or other certified emissions control; ultra-low sulfur diesel = diesel with no more than 15 parts per million sulfur. Grants must be competitive and balanced between replacing buses, installing retrofit equipment, and buying alternative fuel. Priority goes to replacing buses made before model year 1977 and to retrofitting buses made in or after 1991. Retrofit grants may cover up to 100% of costs. Replacement grants may cover up to 50% of cost for certain 2005–2006 engines meeting 1.8 g/bhp-hr (NMHC+NOx) and 0.01 g/bhp-hr PM limits, or for certain 2007–2009 engines meeting EPA standards; grants up to 25% are available for engines meeting 2.5 g/bhp-hr (NMHC+NOx) and 0.01 g/bhp-hr PM for 2005–2006 or for 2007 and later that meet EPA standards. Buses bought or retrofitted with grants must stay in the same fleet at least 5 years and be maintained per manufacturer or State rules. The EPA must try to spread grants nationwide and limit any one State to no more than 10% of funds each year. The EPA must report to Congress by January 31 each year on applications, awards, engine emissions, in-use emissions, and other program details. The EPA had to start an outreach program within 90 days after August 10, 2005, with school-bus groups to explain the program and how to apply. Funding authorized: $55,000,000 for each of fiscal years 2006 and 2007, and whatever sums are needed for fiscal years 2008, 2009, and 2010.
