§ 2757. Optional Evaporative Emission Standards.
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.
Optional Permeation Emission Standard
Effective Date Model Year | Applicability | Requirement 1 Tank Permeation |
|---|---|---|
2007 | Equipment that use gasoline powered small off-road engines with displacements < 80 cc | Fuel tank permeation rate shall not exceed 1.0 grams per square meter per day as determined by TP-901. |
2018 | Small off-road engines with displacements ≤ 80 cc | Fuel tank permeation rate shall not exceed 0.40 grams ROG per square meter of internal surface area per day as determined by TP-901. |
1 Permeation rate must be measured to two significant digits.
Optional Diurnal Emission Standards
(Grams per 24-hour diurnal test)
Effective Date Model Year | Applicability | Requirement 1 |
|---|---|---|
2007 | All equipment that use small off-road engines with displacements > 80 cc to < 225 cc | Diurnal emissions shall not exceed 0.5 grams total hydrocarbons per day as determined by TP-902. |
2018 | Small off-road engines with displacements > 80 to < 225 cc | Diurnal emissions shall not exceed 0.20 g organic material hydrocarbon equivalent per day as determined by TP-902. |
2008 | All equipment that use small off-road engines with displacements ≥ 225 cc | Diurnal emissions shall not exceed 1.0 grams total hydrocarbons per day as determined by TP-902. |
2018 | Small off-road engines with displacements ≥ 225 cc | Diurnal emissions shall not exceed 0.40 g organic material hydrocarbon equivalent per day as determined by TP-902. |
1 Diurnal emissions must be measured to two significant digits.
