A partial zero emissions vehicle is a vehicle that has zero evaporative emissions from its fuel system, has a 15-year (or at least 150,000-mile) warranty on its emission-control components, and meets SULEV tailpipe-emission standards.[1] Definition and history[edit] PZEVs have their own administrative category within the state of California for low emission vehicles.
This vehicle category was created as part of a bargain with the California Air Resources Board (CARB), so that the automobile manufacturers could postpone producing mandated zero emission vehicles (ZEVs), which will require the production of electric vehicles or hydrogen fuel cell vehicles. The vehicles constructed to meet the PZEV requirements must achieve both SULEV (Super Ultra Low Emission Vehicle) exhaust emissions and zero evaporative (fuel system) emissions. How Landfills Work" The basic parts of a landfill, as shown in Figure 3, are: Bottom liner system - separates trash and subsequent leachate from groundwaterCells (old and new) - where the trash is stored within the landfillStorm water drainage system - collects rain water that falls on the landfillLeachate collection system - collects water that has percolated through the landfill itself and contains contaminating substances (leachate)Methane collection system - collects methane gas that is formed during the breakdown of trashCovering or cap - seals off the top of the landfill Each of these parts is designed to address specific problems that are encountered in a landfill.
