PART 59_NATIONAL VOLATILE ORGANIC COMPOUND EMISSION STANDARDS FOR CONSUMER AND 
 
Subpart F_Control of Evaporative Emissions From New and In-Use Portable 
 
Sec. 59.611  What evaporative emission requirements apply under this subpart?

    (a) Hydrocarbon emissions from portable fuel containers may not 
exceed 0.3 grams per gallon per day when measured with the test 
procedures in Sec. Sec. 59.650 through 59.653. This procedure measures 
diurnal venting emissions and permeation emissions.
    (b) For the purpose of this section, portable fuel containers 
include spouts, caps, gaskets, and other parts provided with the 
container.
    (c) The following general requirements also apply for all portable 
fuel containers subject to the standards of this subpart:
    (1) Prohibited controls. The following controls are prohibited:
    (i) For anyone to design, manufacture, or install emission control 
systems so they cause or contribute to an unreasonable risk to public 
health, welfare, or safety while operating.
    (ii) For anyone to design, manufacture, or install emission control 
systems with features that disable, deactivate, reduce effectiveness, or 
bypass the emission controls, either actively or passively. For example, 
you may not include a manual vent that the operator can open to bypass 
emission controls. You may ask us to allow such features if needed for 
safety reasons or if the features operate during emission tests 
described in subpart F of this part.
    (2) Leaks. You must design and manufacture your containers to be 
free of leaks. This requirement applies when your container is upright, 
partially inverted, or completely inverted.
    (3) Refueling. You are required to design your portable fuel 
containers to minimize spillage during refueling to the extent 
practical. This requires that you use good engineering judgment to avoid 
designs that will make it difficult to refuel typical vehicle and 
equipment designs without spillage.
    (d) Portable fuel containers must meet the standards and 
requirements specified in this subpart throughout the useful life of the 
container. The useful life of the container is five years beginning on 
the date of sale to the ultimate purchaser.
