California Code of Regulations › Title 13 - Motor Vehicles › Division 3 - Air Resources Board › Chapter 15 - Additional off-Road Vehicles and Engines Pollution Control Requirements › Article 1 - Evaporative Emission Requirements for off-Road Equipment › Section 2757 - Optional Evaporative Emission Standards

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
The California Air Resources Board recognizes that
					 evaporative emissions can be further reduced by incorporating advanced fuel
					 system designs that reduce or eliminate carburetor and permeation emissions.
					 These optional evaporative emission standards are emission targets that are
					 more stringent than the evaporative emission standards set out in sections
					 2754
					 and
					 2755.
					 These optional evaporative emission standards will be part of a statewide clean
					 air-labeling program. Upon implementation, a manufacturer certifying to an
					 optional evaporative emission standard would be allowed to affix a "Blue Sky
					 Label" on their equipment. This section is applicable through model year 2023.
					 No model year 2024 or later engine may be certified to the emission standards
					 in this section.
