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:

1. 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.”
    
2. 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).
    
3. If the projected 50-state sales is ≥ 4000 units,
   1. 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.
   2. 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)) evaporations 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.

13CCR, section 2754 states that approval by the Executive Officer is required if actively purging canisters that do not meet the requirements of the regulation, such as passively purged carbon canisters, are used.

Active purge refers to the ambient air being drawn through a carbon canister by a vacuum created by the intake system. Passive purge refers to ambient air being drawn through a carbon canister by the vacuum created by normal diurnal temperature variations of the fuel tank temperature.

No, a manufacturer can choose a different CARB approved fuel for evaporative testing than the one used for exhaust testing.

An appropriate default equipment volume for SHED testing would be 3 ft3 for class I engines and 5 ft3 for class II engines.

Yes. According to 13 CCR 2759(a), emissions related and emissions critical parts must be properly labeled in order to identify equipment that meets applicable evaporative standards.

No, nominal fuel tank capacity excludes un-useable volume.

The engine manufacturer declares the maximum power rating in the exhaust certification submission.

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.

Not until the 2006 engine manufacturer model year.

CARB uses the detailed information for emissions inventory calculations.

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.

13 CCR 2759 (c)(4)(C) applies here. Fuel hose should be acceptable for 2006 MY equipment.

13 CCR Section 2759 (h) applies here. Although ARB can approve alternate labels, the manufacturer must have the DOM listed on the emission label.
