EMISSIONS CONTROL COMPLIANCE
Exhaust and Noise Emissions
General
USA
The Federal Clean Air Act, Section 203 (a) (3), states the following concerning the removal
of air pollution control devices or modification of a certified engine to a non-certified
configuration:
(3) For any person to remove or render inoperative any device or element of design installed
on or in a motor vehicle or motor vehicle engine in compliance with regulations under
this part prior to its sale and delivery to the ultimate purchaser, or for any manufacturer or
dealer knowingly to remove or render inoperative any such design after sale and delivery to
the ultimate purchaser.”
Specifically, please note that no person may make such changes prior to the sale and delivery
of the vehicle to the ultimate purchaser, and, in addition, no manufacturer or dealer may take
such action after sale and delivery of the vehicle to the ultimate purchaser. The law provides
a penalty of up to $10, 000 for each violation.
Canada
The same conditions that apply in the USA apply to Canada, with one exception. After the
vehicle is sold to a retail customer, that is, the end user, the jurisdiction controlling the
emission control devices becomes the province in which the vehicle is licensed. No changes
should be made that render any or all of the devices inoperative.
If the owner/operator wishes to make changes to the emission control devices, check with
the provincial authority before changes are made.
Mexico
The same conditions that apply in the USA apply to Mexico. Refer to the Mexican Federal
Law for Emission Control which adheres to EPA regulations. No changes should be made
that render any or all of the emissions control devices inoperative.
If the owner/operator wishes to make changes to the emission control devices, check with
the state authority before changes are made.
