Summary and Rationale for Proposed Regulations

Section 2412. Emission Standards and Test Procedures – New Off-Highway 

Recreational Vehicles and Engines.

This purpose of this section is to identify the exhaust and evaporative emission 

standards, and to incorporate by reference the required test procedures to be used for 

demonstrating compliance with the applicable emission standards of the off-highway 

recreational vehicle category, which is necessary to control the hydrocarbon and carbon 

monoxide emissions from these sources.

(c)(1) The purpose of this subsection is to identify the test procedure documents 

that apply to off-highway recreational vehicles. The amendment clarifies the most 

recent amendment date to these test procedure documents.

(c)(2) The purpose of this subsection is to identify the optional test procedures for 

off-highway recreational vehicles. The amendment clarifies the most recent 

amendment date to these test procedure documents.

(d)(1) The purpose of this subsection is to define the formula that manufacturers 

are to use when using corporate averaging for certification. The amendment clarifies 

the most recent amendment date to the test procedure documents.

California Exhaust Emission Standards and Test Procedures for 1997 and Later 

Off-Highway Recreational Vehicles and Engines.

The purpose of this test procedure is to identify the exhaust emission standards and test 

procedures applicable for off-highway recreational vehicles and engines, which is 

necessary to control the hydrocarbon and carbon monoxide emissions from these 

sources. This test procedure is incorporated by reference in section 2412, title 13, 

California Code of Regulations.

Subpart F

Section 86.513 - 90 Fuel and engine lubricant specifications. 54 FR 14544, 

Apr. 11, 1989.

The purpose of this section is to identify the fuel and engine lubricant specifications that 

are to be used for certification testing. This section was amended to allow off-road 

recreational vehicle manufacturers the optional use of the new California 10-percent 

ethanol-blend gasoline (E10), or other ARB-certified certification test fuel, which ARB 

will adopt for 2015 and subsequent model on-road motor vehicles, for 2013 through

2018 2019 model-year vehicles. Use of this E10, or other ARB-certified certification test 
E-2

fuel, will become mandatory beginning with the 2019 2020 model year. The proposed 

optional and required use of this E10, or other ARB-certified certification test fuel, is 

applicable to only exhaust emission test purposes.

(a)(1)(i) The purpose of this subsection is to identify the fuel to be used for 

certification testing of current production off-highway recreational vehicles. This 

subsection was amended for formatting reasons.

(a)(1)(ii) The purpose of this new subsection is to provide manufacturers the 

alternative of using the new California 10-percent content of ethanol-blend gasoline 

(E10), or other ARB-certified certification test fuel, for model years 2013-2018 2019.

(a)(2) The purpose of this new subsection is to require the new California 

10-percent content of ethanol-blend gasoline (E10), or other ARB-certified certification

test fuel, for all 2019 2020 and later model-year off-highway recreational vehicles.
