(d) (12) Projected California sales data of the en gine family for which certification is requested. Such estimated sales data must include an explanation of the method used

to make the estimate. (13) For zero-emission small off-road equipment, t he certification application shall include the following: (i) Identification and description of the equipme nt covered by the application. (ii) Identification of the power source system we ight (e.g., battery weight) and gross equipment weight rating of the equipment. (iii) Identification and description of the power source system for the equipment. (iv) Results of energy density test. (i v) Projected California sales. (vi ) All information necessary for proper and safe ope ration and maintenance of the equipment, including recharging information and other relevant information as determined by the Executive Officer.

REPLACE WITH: (b) (1) (i) (A) Except as allowed in (B), t T he certification test fuel used for emission testing must be consistent with the fuel s pecifications as outlined in the California Code of Regulations, Title 13, Section 1 960.1, and the latest amendment of

the “California Exhaust Emission Standards and Test Procedures for 2001 and Subsequent Model Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles”, incorporated by reference herein. The test fuel sp ecification should remain consistent from batch to batch. If a particular engine requir es a different octane (or cetane) fuel,

test records should indicate the fuel used. (B) A manufacturer may choose to use a test fuel with up to ten percent ethanol by volume for certification testing , provided that the same fuel has been approved for federal certification testing. (ii) Alcohol-based fuels. Alcohol-based fuels mu st be allowed for emission test purposes when the appropriate emission standar ds with respect to such fuels are a part of these provisions. Such fuels must be as sp ecified in subparagraph (b)(1)(i)

above.
