Sec.  1039.107  What evaporative emission standards and requirements 

apply?



    There are no evaporative emission standards for diesel-fueled 

engines, or engines using other nonvolatile or nonliquid fuels (for 

example, natural gas). If your engine uses a volatile liquid fuel, such 

as methanol, you must meet the evaporative emission requirements of 40 

CFR part 1048 that apply to spark-ignition engines, as follows:

    (1) Describe how your engines control evaporative emissions.

    (2) Present test data to show that equipment using your engines 

meets the evaporative emission standards we specify in this section if 

you do not use design-based certification under 40 CFR 1048.245. Show 

these figures before and after applying deterioration factors, where 

applicable.
