If we agree to hold a hearing related to our decision to order a recall under Sec. 1068.505, we will hold the hearing according to the provisions of 40 CFR 85.1807. For any other issues, you may request an informal hearing as described in 40 CFR 86.1853-01.
Sec. Appendix I to Part 1068--Emission-Related Components
This appendix specifies emission-related components that we refer to for describing such things as emission-related warranty or requirements related to rebuilding engines.

1. Air-induction system.
2. Fuel system.
3. Ignition system.
4. Exhaust gas recirculation systems.
II. The following parts are also considered emission-related components for exhaust emissions:
1. Aftertreatment devices.
2. Crankcase ventilation valves.
3. Sensors.
4. Electronic control units.
III. The following parts are considered emission-related components for evaporative emissions:
1. Fuel Tank.
