§ 2418. Evaporative Emission Standards and Test Procedures.
Currentness
(a) Manufacturers of OHRVs must comply with the following evaporative emission standards for new OHRVs sold or offered for sale in California.
(1) Evaporative emissions from an OHRV may not exceed the following limitations:
(A) The applicable emission standards outlined in Table 1 for either the 72 hour diurnal standard or the steady state diurnal standard. All OHRVs certified to the emission standards below are presumed to demonstrate compliance with federal permeation standards specified in Cal. Code Regs., tit.13, § 2412(b)(2).

__________
(1) Highest 24-hour diurnal test result over three consecutive 24-hour diurnal test periods.
(2) 24-hour diurnal test result plus calculated vented emissions.
(B) All-Terrain Vehicle (ATV) Filler Neck Compatibility Standard.
Beginning with model year 2018, ATVs with fuel tanks that are re-designed to be geometrically different from fuel tanks of 2017 and earlier model years, and have a nominal capacity of greater than 3.5 gallons, must meet the filler pipe sealing surface requirements of Figure 1 of the International Standards Organization 13331:1995(E), published June 1, 1995, which is incorporated by reference herein. Perpendicularly down from the mating surface there must be a minimum of 120 mm (90 mm for nozzle, 5 mm for bellows compression, and 25 mm for extra space fuel flow) to the bottom of the tank.
(2) Zero emission off-road vehicles must produce zero fuel evaporative emissions under any and all possible operational modes and conditions and are, therefore, not required to perform evaporative emissions testing to certify in accordance with section 2419.4.
(b) Small Volume OHRV Manufacturer Design-Based Standard.
(1) In lieu of certifying to the emission standards in subdivision (a), a small volume OHRV manufacturer may certify OHRVs to the design-based standards set out in Table 2. If a Small Volume OHRV Manufacturer elects to certify under this subdivision, they must perform a tip-test as specified in subdivision (a)(1).

__________
(1) Fuel tank permeation standards specified in Cal. Code Regs., tit.13, § 2412(b)(2).
(2) The carbon canister must be actively purged during engine operation.
(c) The test procedures for determining compliance with the standards in subdivisions (a) and (b) are as follows:
(1) The test procedure used for subdivision (a) is TP-933.
(2) The test procedures used for subdivisions (b) and (e) are specified in subdivisions (A), (B), and (C) below:
(A) Fuel hose permeation, as set forth in SAE J1737, as amended May 14, 2013, using the test fuel specified in TP-933 or fuel CE10 as described in Part 1060.515(a)(1), Title 40, Code of Federal Regulations, as amended on February 19, 2015, and incorporated by reference herein, which includes ASTM D471-06, Standard Test Method for Rubber Property -- Effect of Liquids (ASTM D471), last amended October 1, 2006, and incorporated by reference herein. Alternatively, fuel hose permeation may be tested in accordance with section 2412(c)(1).
(B) Fuel tank permeation, as set forth in Part 1060.520, Title 40, Code of Federal Regulations, as amended on April 30, 2010, or Part 1051.515, Title 40, Code of Federal Regulations, as amended on July 13, 2005, and incorporated by reference herein.
(C) The carbon canister, as set forth in TP-902.
(3) Compliance with the fuel tank permeation, hose permeation, and carbon canister working capacity standards in subdivision (b) and subdivision (e) shall be determined in accordance with section 2419.4(b)(3).
(d) Phase-in Schedule.
(1) For model years 2018 through 2021, OHRV manufacturers may phase-in evaporative emission standards specified in subdivision (a) so that 75 percent of all OHRVs sold in model years 2018 through 2021 are compliant with the requirements in section 2419.4, or;
(2) The weighted average of compliant OHRVs must be greater than 75 percent and can include early compliant model year 2017 OHRVs in the model year (MY) 2018 calculation so that: (MY2017%control + MY2018%control) X 0.4 + MY2019%control X 0.3 + MY2020%control X 0.2 + MY2021%control X 0.1 >75 % and percent compliance cannot decrease.
(3) All 2018 through 2021 model year OHRVs that are not subject to these standards pursuant to the phase-in schedule must comply with the evaporative permeation requirements for 2008 and later model year OHRVs, as described in Cal. Code Regs., tit.13, § 2412(b)(2).
(4) The percentage of OHRV fleet averaged across model years 2018 through 2021 must be used to determine compliance with this requirement.
(5) For the purpose of calculating the fleet average, an OHRV manufacturer must use the percentage of OHRVs sold or offered for sale in California for model years 2018 through 2021. An OHRV manufacturer may calculate this average percentage using the projected sales for these model years in lieu of actual sales.
(6) Any OHRV manufacturer that participates in the phase-in period must comply with the administrative requirements in section 2419.4(d).
(7) For model years 2020 and 2021, off-road motorcycles and ATVs that are certified in accordance with the alternative evaporative standards set forth in section 2418(e) shall not be included in the phase-in calculation.
(e) Beginning in model year 2020, off-road motorcycle and ATV manufacturers may comply with the alternative evaporative standards shown in Table 3 or Table 4 in lieu of the emission standards set forth in subdivision (a). The controls specified in Table 3 or Table 4 shall be implemented following the schedule in Table 5:

(2) For motorcycles with engines greater than 112 cc displacement, the carbon canister must be actively purged during engine operation. Motorcycles with engines less than or equal to 112 cc displacement may use either actively purged or passively purged canisters. Active purge refers to ambient air being drawn through a carbon canister by a vacuum created by the intake system. Passive purge refers to ambient air being drawn through a carbon canister by the vacuum created by normal diurnal variations of the fuel tank temperature.
(3) Automatic fuel shutoff is a valve or similar mechanism that completely stops the flow of fuel to the carburetor automatically whenever the vehicle is turned off.
