Why are Canyon County and Kuna different than Ada County?
In 2008, a law was passed requiring a vehicle inspection and maintenance program (or equivalent strategy) in any area of the state classified as a metropolitan statistical area where ozone concentrations are at or above 85% of the federal standard and motor vehicle emissions constitute one of the top two contributing sources.
Currently, the Treasure Valley is the only airshed in the state that meets these conditions. Ada and Canyon Counties share the same airshed. Most of Ada County has had a vehicle emissions testing program in operation since 1984. In June 2010, a vehicle emissions testing program was implemented in Canyon County and the city of Kuna.
I sold or traded the vehicle for which I just received a notice. What should I do?
The Air Quality Board will accept a fully completed signed bill of sale and sold notification, see this website under: Forms/Vehicle Sold. In order to be processed all documents must be submitted.
Idaho Code §49-526 requires a seller to complete and submit a “Release of Liability” within 5 days of selling or trading a vehicle. ITD’s “Notice of Release of Liability” form can be found on ITD’s website.
Why does your program check for emissions control devices?
This program was established based on EPA standards, which state that a visual inspection shall be conducted on all applicable model years. The purpose of the visual inspection is to ensure the vehicle has all the emissions control devices originally required by the manufacturer pursuant to the requirements of the Clean Air Act and they appear to be in good working order. To remove or render inoperative any emissions control device or element of design installed on or in a motor vehicle or its engine in compliance with federal regulations is prohibited and constitutes “tampering.”
“Tampering” is defined by the Clean Air Act of 1970 (revised in 1977) to be the removal or rendering inoperative of any emissions control device or element of design installed on or in a motor vehicle or its engine in compliance with federal regulations prior to its sale and delivery to the ultimate purchaser, or for any person knowingly to remove or render inoperative any emissions control device or element of design after such sale and delivery to the ultimate purchaser (Clean Air Act Section 203(a)(3)(A)).
For the purposes of the Ada County vehicle emissions testing program, vehicles that are found without emissions control devices will fail the emissions test until the vehicle is brought back into compliance with manufacturer emissions control device specifications. Consumers should be aware that if the emissions control device is not working properly and is still intact on the vehicle and the vehicle is under eight (8) years old and under 80,000 miles, they may qualify for a manufacturer warranty for emissions control devices.
Waivers and extensions will not be granted for vehicles with tampering-related emissions test failures in accordance with federal guidelines (40 CFR 51.360(a) (3)).
The original engine within my vehicle has been removed and replaced, what emission control equipment is now required?
Per the Clean Air Act there are limits to what modifications can be made to a vehicle’s configuration and its emissions control equipment. The removal of emissions control equipment is considered tampering. In general, in order to pass an emissions test, the vehicle must meet all applicable emissions control equipment requirements of the engine or chassis whichever is newer.
I want to swap my engine out, what are some of the requirements that my vehicle must meet in order to stay within emissions standards?
Yes. If you change the engine in your vehicle, you must have the emissions control equipment that was required for the chassis year or engine year, whichever is newer.
Can I install a used catalytic converter?
It is considered a violation to sell or install a used catalytic converter unless it has been properly tested and certified. The seller, installer, and owner can all be held liable for tampering if an non-certified catalytic converter is installed.
