(1) No ICE vehicles were added to the California fleet on or after January 1, 2024, with the exception of ICE vehicles purchased pursuant to an exemption or extension specified in section 2015.3 or the ICE vehicle was ordered prior to October 1, 2023; and

(2) The fleet has no ICE vehicles in the California fleet that were otherwise required to be removed as specified in section 2015.1(b) unless the ICE vehicle was granted an exemption or extension.

(1) Backup Vehicle Exemption. Fleet owners may exclude a vehicle from the ICE Vehicle Removal requirements compliance date specified in section 2015.1(b) if the vehicle is designated as a backup vehicle as specified in section 2015.3(a).

(2) Daily Usage Exemption. Fleet owners may request an exemption from the ZEV Addition requirement of section 2015.1(a) to purchase a new ICE vehicle. Fleet owners must request and obtain this exemption pursuant to the criteria specified in section 2015.3(b). The fleet owner must request this exemption no later than one year before the applicable compliance date specified in the ICE Vehicle Removal requirement of section 2015.1(b), and no earlier than when the model year of the ICE vehicle being replaced reaches 16 years old, or when the vehicle reaches 700,000 miles, whichever occurs first.

(3) ZEV Infrastructure Delay Extension. Fleet owners may request an extension from the ICE Vehicle Removal requirements compliance date specified in section 2015.1(b) for an ICE vehicle that is otherwise required to be removed from the fleet. The fleet owner must request and obtain this extension pursuant to the criteria specified in section 2015.3(c). The fleet owner must request this extension no later than 45 calendar days before the applicable compliance date specified in section 2015.1(b) for the ICE vehicle to be replaced.

(4) Vehicle Delivery Delay Extension. Fleet owners may request an extension from the ICE Vehicle Removal requirements compliance date specified in section 2015.1(b) for an existing ICE vehicle that is otherwise required to be removed from the fleet. Fleet owners must request and obtain this extension pursuant to the criteria specified in section 2015.3(d). The fleet owner must request this extension no later than February 1 of the same calendar year as the compliance date specified in the ICE Vehicle Removal requirement specified in section 2015.1(b).

(5) ZEV Purchase Exemptions. Fleet owners must use the exemption in section 2015.3(e)(1) or request the exemption in section 2015.3(e)(2) no later than one year before the compliance date specified in section 2015.1(b) and no earlier than when the model year of an existing ICE vehicle that is otherwise required to be replaced reaches 16 years old, or when the vehicle reaches 700,000 miles, whichever occurs first.

(7) Mutual Aid Assistance. Fleet owners may request an exemption from the ZEV Addition requirement in section 2015.1(a) to purchase new ICE vehicles. Fleet owners must request and obtain this exemption pursuant to the criteria specified in section 2015.3(f)(2). ICE vehicles purchased pursuant to a granted exemption may operate as part of the regular California fleet and are not restricted solely to mutual aid functions.

(8) Five-day Pass. Fleet owners may request a five-day pass to exclude any vehicle from the California fleet for five consecutive days once per calendar year per vehicle in their fleet pursuant to the criteria specified in section 2015.3(g).

(9) Non-repairable Vehicles. Fleet owners that need to temporarily replace a vehicle due to an accident or other onetime event due to circumstances beyond the fleet owner's control, such as fire or catastrophic failure, that damages both the engine and vehicle such that the vehicle is not repairable may request and obtain an exemption from the ZEV Addition requirement specified in section 2015.1(a). If approved, they may purchase a used ICE vehicle of the same configuration and with an engine with the same or newer model year as the non-repairable vehicle no later than 180 calendar days from the date the vehicle became non-repairable. The fleet owner may also exclude it from the ICE vehicle removal requirement specified in section 2015.1(b) until the end of the useful life of the non-repairable vehicle as determined by the criteria specified in section 2015.1(b). The useful life of the replacement will be based on the engine model year of the non-repairable vehicle and the mileage accrued on the non-repairable vehicle plus the mileage accrued on the replacement vehicle. Fleet owners must report the replacement vehicle within 30 calendar days of adding it to the California fleet as specified in section 2015.4 and keep records for both vehicles as specified in section 2015.5(n). By using this option, fleet owners must acknowledge that they knowingly and voluntarily waive the provisions of Health and Safety Code section 43021(a), specific to the replacement vehicle in this section, that would otherwise apply to any purchased commercial motor vehicles as defined in CVC section 34601, except for new ICE vehicles purchased pursuant to an exemption specified in section 2015.3.
