On May 12, 2009, CARB published proposed modifications to staff’s originally proposed certification procedures to provide additional flexibility to conversion system manufacturers, while limiting the potential emissions impacts of converted vehicles and addressing the requirements of the anti-tampering regulation. The proposed modifications provide for a three-tiered certification process. The proposed tiered certification process grants a manufacturer certification based on conversion system production and sales numbers and allows the gradual increase in certification requirements to address increased emissions impact potentials. CARB’s intent is to keep these procedures aligned with the certification procedures for alternative fuel conversions.
The proposed modifications will be considered by the Board in Sacramento, CA on May 28, 2009.
