Current through Register 2024 Notice Reg. No. 50, December 13, 2024

Section 2753 - Certification Requirements and Procedures

(a) Certification.

Small off-road engines or equipment that use small off-road engines subject to this Article must contain evaporative emission control systems. The evaporative emission control systems must be certified annually to the evaporative emission standards set out in sections 2754 through 2757 of this Article by the California Air Resources Board. An Executive Order of Certification for such engines or equipment must be obtained prior to the sale or lease, or the offering for sale or lease, for use or operation in California or the delivery or importation for introduction into commerce in California. Engine manufacturers or equipment manufacturers may apply for an Executive Order of Certification. For model years 2006-2019, applicants must follow the certification procedures outlined in CP-901, Certification and Approval Procedure for Small Off-Road Engine Fuel Tanks, adopted July 26, 2004, or CP-902, Certification and Approval Procedure for Evaporative Emission Control Systems, adopted July 26, 2004, as applicable, which are incorporated by reference herein. For model years 2020 through 2023, applicants must follow the certification procedures outlined in CP-901, adopted July 26, 2004, and amended September 18, 2017, or CP-902, adopted July 26, 2004, and amended September 18, 2017, as applicable, which are incorporated by reference herein. For model year 2018 and 2019, an applicant may follow the certification procedures outlined in CP-901, adopted July 26, 2004, and amended September 18, 2017, or CP-902, adopted July 26, 2004, and amended September 18, 2017, as applicable, in lieu of those in CP-901, adopted July 26, 2004, or CP-902, adopted July 26, 2004, as applicable. For model year 2024 and subsequent model years, applicants must follow the certification procedures outlined in CP-902, adopted July 26, 2004, and last amended January 1, 2023, which is incorporated by reference herein. For model year 2022 and 2023, an applicant may follow the certification procedures outlined in CP-902, adopted July 26, 2004, and last amended January 1, 2023, in lieu of those in CP-901, adopted July 26, 2004, and amended September 18, 2017, or CP-902, adopted July 26, 2004, and amended September 18, 2017, as applicable. An applicant following the certification procedures outlined in CP-902, adopted July 26, 2004, and last amended January 1, 2023, for model year 2022 or 2023 must meet the emission standards for model year 2024 and subsequent model years, as shown in Table 2 or 3 of Section 2754, as applicable. An applicant must also meet the bond requirements in section 2774 before an Executive Order of Certification will be issued for model year 2020 and subsequent model year evaporative families.

(b) Certification of Complete Systems for Engines or Equipment using engines with displacement greater than 80 cc through model year 2023.

Certification of a complete evaporative emission control system is required. An application for certification of an evaporative emission control system to the diurnal emission standards in section 2754 or 2757 of this Article must include a determination of the engine or equipment model in the evaporative family that is expected to exhibit the highest diurnal emission rate relative to the applicable diurnal emission standard and detail the criteria used to make that determination. The applicant must also include one of the following for the engine or equipment model in the evaporative family that is expected to exhibit the highest diurnal emission rate relative to the applicable diurnal emission standard:

(1) Diurnal emission test results, determined using TP-902;

(2) All of the following:

(A) fuel tank permeation data, determined using TP-901,

(B) fuel line permeation data, determined using SAE J1737, SAE J30, SAE J1527, or, only for fuel lines with inner diameter 4.75 mm or less, SAE J2996, and

(C) carbon canister butane working capacity data determined using TP-902 or equivalent; or

(3) The Executive Order numbers approving the fuel tank, fuel line, and carbon canister pursuant to section 2767.1 of this Article.

(c) Certification of Complete Systems for Engines or Equipment using engines with displacement less than or equal to 80 cc through model year 2023.

An application for certification of an evaporative emission control system to the fuel tank permeation standard specified in section 2755 or 2757 must include fuel tank permeation data for the fuel tank in the evaporative family that is expected to exhibit the highest permeation rate relative to the applicable permeation emission standard. The application shall also detail the criteria used to determine which fuel tank in the evaporative family is expected to exhibit the highest permeation rate relative to the applicable permeation emission standard. An applicant may certify an evaporative emission control system for engines with displacement less than or equal to 80 cc to the diurnal emission standards in section 2754 of this Article in lieu of the permeation emission standards in section 2755 and may follow the certification procedures outlined in CP-902, adopted July 26, 2004, and amended September 18, 2017. An application for certification of an evaporative emission control system for engines with displacement less than or equal to 80 cc to the diurnal emission standards in section 2754 of this Article must meet the requirements of section 2753(b) of this Article.

(d) Certification of Complete Systems for Engines or Equipment using small off-road engines for model year 2024 and subsequent model years.

Certification of a complete evaporative emission control system is required. An application for certification of an evaporative emission control system to the hot soak plus diurnal emission standards in section 2754 of this Article must include a determination of the engine or equipment model in the evaporative family that is expected to exhibit the highest hot soak plus diurnal emission rate relative to the applicable hot soak plus diurnal emission standard and detail the criteria used to make that determination. The applicant must also include a test report for a test performed according to TP-902 for the engine or equipment model in the evaporative family that is expected to exhibit the highest hot soak plus diurnal emission rate relative to the applicable hot soak plus diurnal emission standard.

(e) Modifications to the Evaporative Emission Control System.

For previously certified evaporative emission control systems:

(1) Holders may replace the nominal fuel line of a certified evaporative emission control system for which diurnal or hot soak plus diurnal emission test results were submitted as part of the certification application with an equivalent fuel line.

(2) Modification of any certified evaporative emission control systems in any manner other than replacement of the nominal fuel lines with equivalent fuel lines invalidates the certification of the control system. When any evaporative emission control system's certification is invalidated due to an unapproved modification, a new certification is required per CP-902, adopted July 26, 2004, CP-902 adopted July 26, 2004, and amended September 18, 2017, or CP-902 adopted July 26, 2004, and last amended January 1, 2023, as applicable, depending on the model year.

(3) Holders shall notify the Executive Officer in writing of any modification of any certified evaporative emission control system. The notification must include a statement citing the basis for the equivalent fuel line determination.

(f) Reduced Certification Requirements.

Manufacturers meeting the requirements of section 2766 of this Article must be certified annually by the California Air Resources Board by submitting a Letter of Conformance. The Letter of Conformance must include, at a minimum, a statement citing the basis for complying with section 2766. An Executive Order of Certification for such engines or equipment must be obtained prior to the sale or lease, or the offering for sale or lease, or the delivery or importation for introduction into commerce in California of such engines or equipment in California.

(g) A Holder whose Executive Order has been suspended or revoked must submit diurnal or hot soak plus diurnal emission test results, determined using TP-902, for all evaporative families, as described in subsection (b) or (d) of this section, as applicable, according to the following schedule:

(1) For one model year after the first finding of noncompliance;

(2) for five model years after the second finding of noncompliance; and

(3) for ten model years after any subsequent finding of noncompliance.
