Emissions Waiver

What is a waiver?

 

After qualification and approval by our office, a waiver allows you to register a vehicle without complying with the required levels of emissions for carbon monoxide (CO), hydrocarbons (HC), or oxides of nitrogen (NOx).  If a certification of emissions waiver is granted, it is good for one emissions cycle.

What counts as an emissions repair for waiver purposes?

 

Only labor charged by a professional mechanic (someone who performs work as part of a licensed business and conforms to the Garage Repair Act) will be counted towards repair waiver limits.

 

Emission control components include: oxygen sensor, catalytic converter, thermal reactor, EGR valve, fuel filler cap, evaporative canister, PCV valve, air pump, distributor, ignition wires, coil, and spark plugs. The cost of any hoses, gaskets, belts, clamps, brackets or other accessories directly associated with these components may also be applied to the waiver limit.

  

In addition, certain repairs to fuel injection systems, carburetors and internal engine components may apply.
