(1) Exhaust emissions must not exceed:

(2) Evaporative emissions. With the exception of vehicles certified solely with compression-ignition engines, evaporative emissions must not exceed:

(2) The test procedures for determining certification and compliance with the standards for exhaust emissions from all-terrain vehicle, off-road sport vehicle, off-road utility vehicle, and sand car engines (those engines utilizing the engine-based optional standards noted in (b) above) are set forth in “California Exhaust Emission Standards and Tests Procedures for 1995-2004 Small Off-Road Engines,” adopted March 20, 1992, and as last amended July 26, 2004, which is hereby incorporated by reference. For 2013 and later model years, the test fuel requirements for engines utilizing such optional standards are specified in § 1065.701, of the “California Exhaust Emission Standards and Test Procedures for New 2013 and Later Small Off-Road Engines; Engine-Testing Procedures (Part 1065),” adopted October 25, 2012, which is hereby incorporated by reference.

n = Off-highway recreational vehicle engine families.

PROD_jx = Number of units in engine family j produced for sale in California in model year x

STD_jx = The manufacturer designated exhaust emission standard for engine family j in model year x, which shall be determined by the manufacturer subject to the following conditions: (1) no individual engine family exhaust emission standard shall exceed 10 g/km HC or 20 g/km HC + NO_x, and (2) no engine family designation or engine family exhaust emission standard shall be amended in a model year after the engine family is certified for the model year, and (3) prior to sale or offering for sale in California, each engine family shall be certified in accordance with “California Exhaust Emissions Standards and Test Procedures for 1997 and Later Off-Highway Recreational Vehicles and Engines” adopted November 22, 1994 and as last amended October 9, 2019, and shall be required to meet the manufacturer's designated HC exhaust emission standard as a condition of the certification Executive Order. Prior to certification the manufacturer shall also submit estimated production volumes for each engine family to be offered for sale in California.

STD_ca = A manufacturer's corporate average HC exhaust emissions from those California off-highway recreational vehicles subject to the California corporate average HC exhaust emissions standard, as established by an Executive Order certifying the California production for the model year. This order must be obtained prior to the issuance of certification Executive Orders for individual engine families for the model year and shall include but not be limited to the following requirements in subsection (e) below:

(2) For the optional engine-based testing, compliance with a standard to be applied as a “corporate average” shall be determined as follows:

where

n = the number of small off-road engine families.

FEL = the Family Emission Level for an engine family.

Sales_j = the eligible sales of engine family _j.

where

Power_j = the sales-weighted maximum modal power (in kilowatts) of engine family j, or an alternative approved by the Executive Officer.

EDP_j = the Emissions Durability Period of engine family j.

Load Factor = the Load Factor is 47% (i.e., 0.47).

STD_ca = A manufacturer's corporate average HC+NO_x exhaust emissions from those California off-highway recreational vehicles subject to the California corporate average HC+NO_x exhaust emissions standard, as established by an Executive Order certifying the California production for the model year. This order must be obtained prior to the issuance of certification Executive Orders for individual engine families for the model year and shall include but not be limited to the following requirements in subsection (e) below:

(2) The manufacturer's average HC or HC+NO_x exhaust emissions, as applicable, shall meet the corporate average standard at the end of the manufacturer's production for the model year.

(3) Production and sale of vehicles which result in noncompliance with the California standard for the model year shall cause a manufacturer to be subject to civil penalties, according to applicable provisions of the Health and Safety Code. All excess emissions resulting from noncompliance with the California standard shall be made up in the following model year.

(4) For a period of up to one year following the end of the model year, for each model the manufacturer shall submit California sales and registration data as it becomes available.

(2) On or after January 1, 1997, manufacturers may not produce for sale in federal ozone non-attainment areas of California new, non-zero emission engines for golf carts.

(3) On or after January 1, 1999, no new engines 90 cc or less may be produced for sale to replace off-road motorcycle and all-terrain vehicle engines, unless those engines comply with the emission control standards in effect at the time of replacement.

(4) On or after January 1, 2007, no new engines may be produced for sale to replace engines in off-road sport vehicles, off-road utility vehicles, or sand cars, unless those engines comply with the emission control standards in effect at the time of replacement.

(1) 1997 and later off-road motorcycles, all-terrain vehicles, golf carts;

(2) 2007 and later off-road sport vehicles, off-road utility vehicles, and sand cars.
