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 EVAP 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.)
2009 and Later Model Years
For 2009 and later model years, the evaporative families that are certified under 11/9/2015 Page 10 of 16 the small production volume tank exemption must meet the following requirements:
- All units must be labeled in accordance with the FAQ 1-40 language:
“THIS EQUIPMENT MEETS CALIFORNIA (13 CCR SECTION 2766(b)) EVAP EMISSION REGULATIONS FOR SMALL OFF-ROAD ENGINES FOR 20XX MODEL YEAR.”
- If the projected 50-state sales is <4000 units, manufacturers do not have to submit any additional documentation to demonstrate that their total California sales is 400 or fewer units (since manufacturers’ data suggests that typical California sales are less than 10 percent of 50-state sales).
- If the projected 50-state sales is ≥ 4000 units,
- Recommended Option: Manufacturers print and use up to 400 small production volume tank exemption labels only. In addition, a serial number must be included on each label to ensure that the total number of labels that are issued does not exceed 400 units.
- Alternatives: If manufacturers choose not to limit the small production volume tank exemption labels to 400 or fewer units, they are required to either i.) submit an annual year-end actual California sales report for a period of 5 years from the beginning of the specific model year, OR ii.) obtain prior CARB approval on an alternate method of assurance not presented in this response.
To assist in the certification process, manufacturers must provide a description of how they plan to demonstrate that their total California sales of a particular fuel tank is 400 or fewer units per model year in the Additional Comments page (item 66) of the certification application.
2006 – 2008 Model Years
Manufacturers who have already certified for 2006 and 2007 model years under the small production volume tank exemption do not have to submit any additional documentation.
Manufacturers who have applied or are applying for 2008 small production volume tank exemptions for their 50-state evaporative families and have projected 50-states sales ≥ 4000 units will be required to submit a year-end actual California sales report within 90 days after the end of the model year (no later than March 31, 2009). Manufacturers that have projected 50-states sales of <4000 units do not have to submit any additional documentation.
As per Section 2759, equipment manufacturers (and engine manufacturers where applicable) must include a label on their equipment indicating that the equipment conforms to California regulations. However, Section 2759(c)(4)(E), the unconditional statement of compliance, should read:
”THIS EQUIPMENT MEETS CALIFORNIA (13 CCR SECTION 2766(b)) EVAP EMISSION REGULATIONS FOR SMALL OFF-ROAD ENGINES FOR 20XX MODEL YEAR.”
The requirements of Section 2759(c)(4)(A), (B), and (D) are still in effect for the label, as is the remainder of Section 2759.
A manufacturer can certify to the performance standards of 13CCR, section 2754 (a), or to the design standards of 13 CCR section 2754 (b) with a passively purged carbon canister if the Executive Officer approves the running loss determination before the certification process. For a manufacturer certifying a passively purged system, adequate test data must be included in the certification application that allows an engineer to conclude that running loss emissions are not freely emitted into the atmosphere unattenuated during engine operation. At a minimum, the running loss demonstration test data needs to show that the evaporative system could handle a running loss event after repeated diurnal cycles and is:
- designed to control running loss emissions from being emitted into the atmosphere
- Data example 1: For a carbon canister controlled fuel tank design, provide carbon canister capture and loss gravimetric measurements before and after a running loss event
- Data example 2: Ambient and fuel tank head space pressure and vacuum measurements throughout a running loss event
- Designed in a manner that protects the system from exposure to liquid fuel, extreme temperatures or pressures, or other conditions that would make the system less efficient or inoperable
- Design example 1: Evidence fuel slosh is not interfering with carbon canister performance
- Design example 2: Temperature shielding or air flow benefiting the evaporative emissions system
- A CARB control number will be assigned to each approved running loss determination and should be referenced in a SORE equipment Executive Order 11/9/2015 Page 9 of 16 application. The running loss determination Executive Officer approval request package is sent to:
Catherine Dunwoody, Chief
Monitoring and Laboratory Division
Air Resources Board
P.O. Box 2815
Sacramento, CA 95812
At a minimum, the package should include a letter requesting the running loss determination, a functional description of the evaporative emission system, the test procedure, the test data, and an interpretation of the test results.
The certificate holder is responsible for communicating to the producer of the finished product the terms of compliance with the Executive Order. The finished product can include configurations that emit at lower levels (e.g. smaller fuel tanks, larger capacity canisters) than the worst case tested and documented in the certification submission.
Yes. A manufacturer may report just the base engine/equipment model(s), provided all variations of the base model are equipped with identical evaporative controls. The naming convention for base engine/equipment model(s) reported must contain sufficient common identifiers to associate specific model variation to its appropriate base model. For design based certification, manufacturers must report the component(s) (via reporting the component Executive Order number) associated with each engine model in the Model Summary page of the certification application.
A list of these equipment types is provided on the following webpage: https://www.arb.ca.gov/msprog/offroad/preempt.htm. The federal Clean Air Act prohibits California from regulating new construction or farm equipment rated below 175 horsepower. Definitions for construction equipment and farm equipment are given in 40 CFR Part 1074.5. The equipment types that are in these categories are therefore called “preempt.”
