(a) The Congress finds and declares that—
(1)
gasoline and diesel fuel for vehicular use are in short supply and constitute a sizable portion of domestic petroleum consumption;
(3)
methane is in more abundant domestic supply than petroleum products, is the primary component of natural gas and can be derived in increased quantities from coal, biomass, waste products, and other renewable resources;
(5)
test results to date indicate that methane use as a substitute for gasoline as a motor fuel can result in emission reductions;
(b) It is therefore declared to be the policy of the Congress in this chapter to—
(4)
promote the substitution of methane-fueled vehicles for gasoline- and diesel-powered vehicles currently used on farms and in fleet operations, particularly in areas where such substitution would facilitate plans to meet air quality standards set under the Clean Air Act, as amended [42 U.S.C. 7401 et seq.]; and
