The retest must be performed on the same engine and/or equipment that generated the original test results. No additional preconditioning is required if the fuel system has continuously contained fuel subsequent to the original test.

Good engineering practices are used to calculate surface areas for irregular shaped tanks.

In years that you are required to meet fuel hose permeation standards only, the evaporative family code can be omitted from the label. However, the label must still contain an unconditional statement of compliance for evaporative emissions.

The effective date applies to the model year of the generator.

Yes, 13 CCR Section 2753 (d) applies.

Yes. However, the first two characters of the evaporative family code must be as specified by CP-902.

As defined in Cal. Code Regs., title 13, section 2752(a)(9), “Evaporative Family” means a class of off-road engines or equipment that are grouped together based on similar fuel system characteristics as they relate to evaporative emissions. For equipment less than or equal to 80 cc, the engine family and evaporative family are considered equivalent. For integrated equipment greater than 80 cc the engine family and the evaporative family may be considered equivalent at the manufacturer’s discretion

Footnote 4 was inadvertently removed from proposed 15-day modifications, published May 14, 2004, when the regulations were finally approved by the Office of Administrative Law. The footnote read as follows: “4 Applies to small production volume tanks exempted pursuant to section 2766.”

Yes. For the model years when only a low permeation hose is required, the manufacturer can omit the evaporative code from the label. However, the label must still contain an unconditional statement of compliance.

Manufacturers meeting the small production volume exemption in Section 2766 must certify equipment annually pursuant to Section 2753 (d). However, equipment is not required to be configured with low permeation fuel hoses and carbon canisters or conform to fuel cap performance standards until model year 2010.

No. Compression-ignited engines are not regulated in the small offroad engine regulations.

Yes, running loss emissions that are combusted are considered controlled.

Yes.  Any changes to a certified evaporative emission control system will require the certification holder to submit a running change request.

No. The regulations do not specify the technology that must be used.

For equipment manufactured prior to or during a specific model year, the engine or equipment must comply with the respective exhaust and evaporative standards in effect for that model year in which it was produced. In the example described above, as long as the 2007 model year engine was compliant with the 2007 model year exhaust standards, and the 2008 model year equipment is compliant with 2008 model year evaporative requirements, a 2008 model year evaporative certification could be issued for the equipment.
