Yes. When it comes to using two carbon canisters on a separate two tank system, CARB approves the use of one canister for each separate tank as long as the canister’s working capacity is compatible to the size of the tank.
However, when it comes to using multiple canisters in sequence for one large fuel tank, CARB would require that the canister manufacturer apply for a new component EO under the innovative products program. Canisters in sequence must be tested per TP-902 and the working capacity data should be submitted with the request for a new component EO. As with single carbon canister EOs, the working capacity of the canisters in sequence should determine the maximum fuel tank capacity.
Manufacturers using a component whose EO has been revoked will be required to stop installing that component on engines or equipment once the 11/9/2015 Page 14 of 16 EO is revoked. If they are unable to substitute another certified component or otherwise meet the requirements set forth in sections 2754 through 2757 of the regulation, they can apply for a variance pursuant to section 2768.
In general, 13 CCR Section 2767.1 requires the manufacturer to submit supporting documentation that quantifies the emissions data from 5 component samples, including the test method(s) used to generate the data. The manufacturer needs to provide this information in a letter on company letterhead to CARB requesting component certification. An authorized company representative must sign the letter. The manufacturer should also submit a sample of the component, drawings, installation and maintenance instructions, and identify limits or conditions on component usage. The manufacturer may elect to provide additional information regarding the materials used in the design and construction of the component. The following requirements are specific to each type of component. Deviation from these requirements constitutes an alternative test procedure and requires pre-approval.
Fuel Hose Component Certification
- Fuel hoses tested must have the smallest inside diameter for the production range;
- Testing must be conducted at a constant 40C, or higher;
- Test fuel used must be Cert fuel, Indolene, CE10, or CM15; and
- Permeation rate must be measured following SAE J1737.
Fuel Tank Component Certification
- Fuel tanks tested must have the smallest ratio of tank volume to internal surface area for the production range;
- Testing must be conducted at a constant 40C;
- Test fuel used must be Phase II Cert fuel, Indolene, LEV III Certification Gasoline Fuel (E10) – with approval, or EPA Certification gasoline with 10 percent ethanol (IE10) – with approval; and
- Permeation rate must be measured following TP-901.
Carbon Canister Component Certification
- Working capacity must be measured following TP-902, including durability testing prior to measurement of working capacity;
- Canister must be loaded with butane mixed 50/50 by volume with air or nitrogen; and
- Manufacturer must specify the largest tank from which the carbon canister can control vapors and still meet the performance requirements in TP-902.
Yes, for SSIE and LSIE (<1 Liter) equipment, manufacturers may use a combined label for equipment that meets both U.S. EPA and ARB evaporative emission requirements. Manufacturers shall include all of the California label requirements per section 2759. Staff may also accept the addition of the following U.S. EPA information:
- For the label heading, “Emission Control Information” may be substituted for “Important Emissions Information.”
- For a design-based certification product label, the addition of “Using Certified Components” at the end of the compliance statement.
- For the combined compliance statement: “This equipment meets U.S. EPA and California evaporations emission regulations for small off-road engines for 20XX model year."
(Manufacturers may use a similar structure for SSIE exhaust and LSIE <1 Liter exhaust and evap labels.)
