CALIFORNIA EXHAUST EMISSION STANDARDS AND TEST PROCEDURES 

FOR 2001 AND SUBSEQUENT MODEL 

PASSENGER CARS, LIGHT-DUTY TRUCKS AND MEDIUM-DUTY VEHICLES

 The provisions of Subparts B, C, and S, Part 86, Title 40, Code of Federal 

Regulations, as adopted or amended on May 4, 1999 or as last amended on such 

other date set forth next to the 40 CFR Part 86 section title listed below, and to the 

extent they pertain to exhaust emission standards and test procedures, are hereby 

adopted as the “California Exhaust Emission Standards and Test Procedures for 

2001 and Subsequent Model Passenger Cars, Light-Duty Trucks, and Medium-Duty 

Vehicles,” with the following exceptions and additions.

 3.1.8. Subparagraph (g): Add the following: The manufacturer shall 

obtain approval from the Executive Officer for all emission control label formats and 

locations prior to use. Approval of the specific tune-up settings is not required; 

however, the format for all such settings and tolerances, if any, is subject to review. 

If the Executive Officer finds that the information on the label is vague or subject to 

misinterpretation, or that the location does not comply with these specifications, he 

or shethe Executive Officer may require that the label or its location be modified 

accordingly. Samples of all actual production emission control labels used within a 

test group shall be submitted to the Executive Officer within thirty days after the start 

of production. The Executive Officer may approve alternate label locations or may, 

upon request, waive or modify the label content requirements provided that the 

intent of these requirements is met. If the Executive Officer finds any motor vehicle 

or motor vehicle engine manufacturer using emission control labels which are 

different from those approved or which do not substantially comply with the 

readability or durability requirements set forth in these labeling requirements, the 

Executive Officer may invoke §2109, title 13, CCR.
