# §1051.110. What evaporative emission standards must my vehicles meet?


Your new vehicles that run on a volatile liquid fuel (such as gasoline) must meet the emission standards of this section over their full useful life. Note that [§ 1051.245](/cfr/40/1051.245.md) 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](/cfr/40/subpartF.md) of this part. You may generate or use emission credits under the averaging, banking, and trading (ABT) program, as described in [subpart H](/cfr/40/subpartH.md) 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](/cfr/40/subpartF.md) of this part. Use the inside diameter of the hose to determine the surface area of the hose.
- (c) You may certify your fuel tanks and fuel lines under the provisions of [40 CFR part 1060](/cfr/40/part1060.md). You may also specify in your application for certification that you are using components that have been certified by the component manufacturer.
