§ 2303. Determination of Total Projected Maximum Volumes of Designated Clean Fuels.
The executive officer shall determine the total projected maximum volume of each designated clean fuel for each year, at least fourteen months before the start of the year, in accordance with this section.
(a) Identification of designated clean fuels. The executive officer shall determine what designated clean fuels are expected to be used as the certification fuel in low- emission vehicles in the year. This determination shall be based on registration records of the Department of Motor Vehicles and projected production estimates submitted by motor vehicle manufacturers to the executive officer pursuant to the “California Exhaust Emission Standards and Test Procedures for 1988 Through 2000 Model Passenger Cars, Light-Duty Trucks and Medium-Duty Vehicles” as incorporated by reference in Title 13, California Code of Regulations, section 1960.1, and the “California Exhaust Emission Standards and Test Procedures for 2001 and Subsequent Model Passenger Cars, Light-Duty Trucks and Medium-Duty Vehicles” as incorporated by reference in Title 13, California Code of Regulations, section 1961.
The estimate shall be the sum of: [i] the number of low- emission vehicles certified on the fuel that vehicle manufacturers have projected to be produced in the corresponding model year and the prior model year for sale in California; [ii] one-sixth of the number of low-emission vehicles certified on the fuel that vehicle manufacturers project to produce for the model year that is two years prior to the year for which the calculations are being made; and [iii] the number of low-emission vehicles certified on the fuel that are registered with the Department of Motor Vehicles through July 30 of the year two years prior to the year for which the estimates are being made.
(2) The vehicle manufacturers' projections used for the estimates made under this section 2303(b) shall be the reports of projected production data submitted by motor vehicle manufacturers to the executive officer pursuant to the “California Exhaust Emission Standards and Test Procedures for 1988 Through 2000 Model Passenger Cars, Light-Duty Trucks and Medium-Duty Vehicles” as incorporated by reference in Title 13, California Code of Regulations, section 1960.1, or “California Exhaust Emission Standards and Test Procedures for 2001 and Subsequent Model Passenger Cars, Light-Duty Trucks and Medium-Duty Vehicles” as incorporated by reference in Title 13, California Code of Regulations, section 1961.
(c) Determination of total projected maximum volumes of designated clean fuel. For each designated clean fuel identified pursuant to section 2303(a), the executive officer shall estimate the total projected maximum volume (TPMV) of the designated clean fuel for the year. The total projected maximum volume for each designated clean fuel shall be the sum of the maximum demand volumes (MXDV) calculated by model-year and vehicle class (passenger car, light-duty truck, or medium-duty vehicle).
The following equation shall be used to calculate total projected maximum volumes:
)
Where: TPMV is the total projected maximum volume (gasoline equivalent gallons per year for a liquid fuel and therms per year for a gaseous fuel) for a particular clean fuel.
MXDV is the maximum demand volume for a particular clean fuel within vehicle class i and model-year y as calculated in the next paragraph of text.
Model-year y is, in turn, each vehicle model-year since and including 1994.
Vehicle class i is, in turn, each of three classes of vehicles: passenger cars (PC), light-duty trucks (LDT) or medium-duty vehicles (MDV).
Maximum demand volume for a designated clean fuel (for a given model-year and vehicle class) shall equal the number of vehicles (as determined in section 2303(b)) in a particular vehicle class certified on a particular fuel, multiplied by the average miles travelled per year per vehicle by those vehicles, divided by the average fuel economy of those vehicles.
The following equation shall be used to calculate maximum demand volumes:
MXDV
(vehicle class i, model year y) =
((number of vehicles certified on fuel) x (AMT per vehicle))/((average fuel economy))
Where: MXDV is the maximum demand volume (gasoline equivalent gallons per year for a liquid fuel and therms per year for a gaseous fuel) for a particular clean fuel within vehicle class i and model year y.
Vehicle class i is one of three possible classes of vehicles--passenger cars (PC), light-duty trucks (LDT) or medium-duty vehicles (MDV).
Model-year y is, in turn, each vehicle model-year since and including 1994.
Number of vehicles certified on fuel shall be determined pursuant to section 2303(b), and shall be calculated separately for vehicles of the same model year and vehicle class (PC, LDT, MDV).
AMT per vehicle is the average vehicle miles traveled per year per low-emission vehicle, based on annual mileage accrual rates for motor vehicles for a specific model year and vehicle class derived from the current version of the ARB's EMFAC emission inventory model and other reasonably available relevant information.
Average fuel economy represents the estimated fuel economy in miles per gasoline equivalent gallon (mpg) (or miles per therm in the case of gaseous fuels) of low-emission vehicles of the same model year and vehicle class. The average fuel economy estimates shall be determined by the executive officer based on the fuel economy estimates provided by the vehicle manufacturers pursuant to the “California Exhaust Emission Standards and Test Procedures for 1988 Through 2000 Model Passenger Cars, Light-Duty Trucks and Medium-Duty Vehicles” and the “California Exhaust Emission Standards and Test Procedures for 2001 and Subsequent Model Passenger Cars, Light-Duty Trucks and Medium-Duty Vehicles,” which are incorporated by reference in Title 13, California Code of Regulations, sections 1960.1 and 1961, and on other reasonably available relevant information.
(d) Characterization of certain dual-fuel or flexible-fuel vehicles. Any dual-fuel or flexible-fuel vehicle which is certified to meet, while operated on gasoline or diesel fuel, low-emission vehicle standards at least as stringent as the most stringent low-emission vehicle standards to which the vehicle is certified while operated on a fuel other than gasoline shall not be included in the determination pursuant to section 2303(b) of the number of low-emission vehicles certified on a designated clean fuel.
