          Subpart B_Emission Standards and Related Requirements
 
Sec. 1051.110  What evaporative emission standards must my vehicles meet?

    All of your new vehicles must meet the emission standards of this 
section over their full useful life, as specified in this section. 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 use the averaging, banking, and trading 
provisions of subpart H of this part to show compliance.
    (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 the hose to determine 
the surface area of the hose.
