  EPA and CARB Regulations for Fuel Tanks
The EPA has been phasing in a reduction of fuel permeation under the Clean Air Act. Many other industries, such as passenger automobiles, have already been affected by these reductions.
Motorcycle and Recreational Vehicles
This category includes motorcycles and recreational vehicles such as snow mobiles, dirt-bikes and ATVs. Fuel tanks for these vehicles are commonly blow molded HDPE tanks with permeation rates greater than 8.0 g/m2/day. New EPA regulations restrict permeation rates to less than 1.5 g/m2/day.
EPA regulations for recreational vehicles were enacted in 2002 and will take effect in 2008.
Lawn and Garden
EPA regulations for fuel permeation of lawn and garden equipment are under development. A permeation limit of 1.5 g/m2/day (Fuel CE10) is projected, with regulations to take effect in 2010.
Marine Vehicles
EPA regulations for fuel permeation of marine vehicles are also under development, with regulations to take effect in 2007/2008.
CARB Regulations
The California Air Resources Board (CARB) has implemented premeation restrictions for the small off-road (SORE) class of vehicles:
|
Permissible Permeation Rates |
| Year: |
2007/2008 |
2012/2013 |
| Engines smaller than 80 cc |
2.0 g/m2/day |
2.0 g/m2/day |
|
Engines larger than 80 cc |
2.5 g/m2/day |
1.5 g/m2/day |
With permeation rates restricted to such low levels, the blow-molded and rotomolded polyethylene solutions of today will not pass these regulations. OEMs and component manufacturers are left with few alternatives.
The use of Petro-SealTM technology using Rilsan® polyamide enables tank manufacturers and OEMs to meet EPA and CARB specs more cost effectively than steel alternatives. Learn more.
