Off-Road Small Spark-Ignition Engine Emission Regulations

12.7 (1) Engines of the 2019 and later model years with a complete fuel system shall conform to the following standards:

• (a) for engines that are designed to be used in a non-handheld machine for the useful life set out in section 112 of subpart B of CFR 1054,

  • (i) for non-metallic fuel lines, the permeation emission standards set out in paragraph 102(d)(2) of subpart B of CFR 1060,

  • (ii) for non-metallic fuel tanks, the permeation emission standards set out in paragraph 103(b) of subpart B of CFR 1060,

  • (iii) for metal fuel tanks, the standards set out in paragraph 103(f) of subpart B of CFR 1060,

  • (iv) except for a wintertime engine, the running loss emission standards set out in the following paragraphs of subpart B of CFR 1060:

    • (A) paragraph 104(b)(1),

    • (B) paragraph 104(b)(2), or

    • (C) paragraph 104(b)(3), if an approved Executive Order of the California Air Resources Board in respect of the engine’s running loss emissions has been included in the evidence of conformity,

  • (v) at the company’s choice, instead of the standards described in subparagraphs (i) and (ii), the diurnal emission standards set out in paragraph 105(e) of subpart B of CFR 1060, and

  • (vi) the evaporative emission standards set out in paragraphs 101(f)(1) and (3)(i) of subpart B of CFR 1060;

• (b) for engines that are designed to be used in a handheld machine — other than the engines referred to in paragraph (c) — for the useful life of the engine set out in section 110 of subpart B of CFR 1054,

  • (i) for non-metallic fuel lines, the permeation emission standards set out in paragraph 102(d)(2) of subpart B of CFR 1060,

  • (ii) for non-metallic fuel tanks, the permeation emission standards set out in paragraph 103(b) of subpart B of CFR 1060,

  • (iii) for metal fuel tanks, the standards set out in paragraph 103(f) of subpart B of CFR 1060, and

  • (iv) the evaporative emission standards set out in paragraph 101(f)(3)(i) of subpart B of CFR 1060; and

• (c) for engines that are designed to be used in a handheld cold weather machine for the useful life set out in section 110 of subpart B of CFR 1054,

  • (i) for non-metallic fuel lines, the permeation emission standards set out in paragraph 102(d)(3) of subpart B of CFR 1060,

  • (ii) for non-metallic fuel tanks, the permeation emission standards set out in paragraph 103(b) of subpart B of CFR 1060,

  • (iii) for metal fuel tanks, the standards set out in paragraph 103(f) of subpart B of CFR 1060, and

  • (iv) the evaporative emission standards set out in paragraph 101(f)(3)(i) of subpart B of CFR 1060.

(2) For the purposes of paragraph 1(c), a handheld cold weather machine means any of the following handheld machines: a chainsaw, cut-off saw, clearing saw, brush cutter in which an engine with a total engine displacement that is greater than or equal to 40 cm³ is installed, commercial drill, ice auger and earth auger that is also designed to be used as an ice auger.
