Sec.  1051.110  What evaporative emission standards must my vehicles meet?

    Your new vehicles must meet the emission standards of this section 
over their full useful life. Note that Sec.  1051.245 allows you to use 
design-based certification instead of generating new emission data.
    (a) Beginning with the 2008 model year, permeation emissions from 
your vehicle's fuel tank(s) may not exceed 1.5 grams per square-meter 
per day when measured with the test procedures for tank permeation in 
subpart F of this part. You may generate or use emission credits under 
the averaging, banking, and trading (ABT) program, as described in 
subpart H of this part.
    (b) Beginning with the 2008 model year, permeation emissions from 
your vehicle's fuel lines may not exceed 15 grams per square-meter per 
day when measured with the test procedures for fuel-line permeation in 
subpart F of this part. Use the inside diameter of
