(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.
(d)(1) For chassis-based testing, compliance with a standard to be applied as a “corporate average” shall be determined as follows:
)
n = Off-highway recreational vehicle engine families.
PRODjx = Number of units in engine family j produced for sale in California in model year x
STDjx = 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 + NOx, 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.
STDca = 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.
Salesj = the eligible sales of engine family j.
where
Powerj = the sales-weighted maximum modal power (in kilowatts) of engine family j, or an alternative approved by the Executive Officer.
EDPj = the Emissions Durability Period of engine family j.
Load Factor = the Load Factor is 47% (i.e., 0.47).
STDca = A manufacturer's corporate average HC+NOx exhaust emissions from those California off-highway recreational vehicles subject to the California corporate average HC+NOx 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:
(e)(1) During the manufacturer's production year, for each vehicle produced for sale in California, the manufacturer must provide the following information to the Executive Officer within 30 days after the last day in each calendar quarter:
(c)(1) The test procedures for determining certification and compliance with the standards for exhaust and evaporative emissions from new off-highway recreational vehicles are set forth in “California Exhaust Emission Standards and Test Procedures for 1997 and Later Off-Highway Recreational Vehicles and Engines,” adopted November 22, 1994, and last amended October 9, 2019, which are hereby incorporated by reference and which in turn incorporate by reference Subparts E and F of Part 86, and Subparts A, B, C, F and I of Part 1051, Title 40, Code of Federal Regulations. Manufacturers of the following are not required to perform emissions testing, but must file an application of certification and comply with the administrative requirements outlined in the procedures to certify their vehicles for sale in California:
(f) Off-road motorcycles and ATVs of model years 2003 through 2021, and engines used in such vehicles, that do not meet the emissions standards in subsection (b) above may operate only during certain periods of time at certain off-highway vehicle (OHV) riding areas until January 1, 2025. Section 2415 of this Article lists these California OHV riding areas and their associated riding seasons for off-highway recreational vehicles that are subject to use restrictions.
(g)(1) On or after January 1, 1997, no new engines greater than 90 cc may be produced for sale to replace off-road motorcycles, all-terrain vehicles and engines used in such vehicles, unless those engines comply with the emission control standards in effect at the time of replacement.
(i) No crankcase emissions shall be discharged into the ambient atmosphere from the following vehicles, or from engines used in such vehicles:
