Title 42 › CHAPTER 149 — NATIONAL ENERGY POLICY AND PROGRAMS › SUBCHAPTER VII — VEHICLES AND FUELS › Part F — Diesel Emissions Reduction › § 16132
The EPA must use 70 percent of the money for this program each year to award competitive grants, rebates, or low-cost loans that cut diesel pollution and lower people’s exposure, especially in areas the EPA says have poor air. At least 95 percent of the money must go to projects using certified engine setups or EPA-verified technologies. No more than 5 percent may go to new, emerging technologies, and makers who want that money must send a test plan and verification filing to the EPA or the California Air Resources Board. The EPA must run a simpler, faster application process that helps small fleet owners and may let applicants include results from competitive bids. Applications must describe local air quality and diesel pollution, the project and its costs, the technologies to be used, expected benefits using EPA- or National Academy-approved methods, equipment age and life, diesel fuel sulfur for nonroad projects, and how results will be monitored. The EPA will give top priority to projects that improve public health most, are most cost-effective, serve high-density or poor-air-quality areas (including nonattainment/maintenance areas, Federal Class I areas, or places with toxic concerns), cut pollution from big diesel sources (like ports, truckstops, rail yards, schools, construction sites, and distribution centers), use long-life technologies, and save diesel fuel. Grants, rebates, or loans can pay for retrofit technologies, repowers, or part of the cost of new diesel engines, and for verified anti-idling projects for buses, medium- and heavy-duty trucks, marine engines, locomotives, and nonroad equipment used in construction, cargo handling (including ports and airports), agriculture, mining, or energy. Funds cannot pay for emission cuts that federal law already requires, except for requirements in an EPA-approved State implementation plan; voluntary measures are not treated as required. The EPA may hire private or nonprofit contractors to run rebate and loan programs if they can sell, finance, or upgrade diesel vehicles or equipment. Within 60 days after an award, the EPA must post online totals and dollar amounts and a technology breakdown for owner rebates and loans, and descriptions of other funded applications.
