Leroy Engineering Emissions Statement
The EPA Clean Air Act prohibits by law any tampering, modification, or removal of the emission control system in street-legal cars driven on public roadways, punishable by extensive fines.
Under the Clean Air Act Section 203(a), it is illegal:
"(3)(A) 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 subchapter prior to its sale and delivery to the ultimate purchaser, or for any person knowingly to remove or render inoperative any such device or element of design after such sale and delivery to the ultimate purchaser; or
"(B) for any person to manufacture or sell, or offer to sell, or install, any part or component intended for use with, or as part of, any motor vehicle or motor vehicle engine, where a principal effect of the part or component is to bypass, defeat, 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 subchapter, and where the person knows or should know that such part or component is being offered for sale or installed for such use or put to such use."
At this time, exemptions are made in Ohio and some other states for off-road/race-only competition vehicles used only in sanctioned racing applications such as the SCCA. Leroy Engineering won't modify vehicles that are used in states that do not have a similar exemption.
Off-road/race-only vehicles are those that have had modifications made to their emission system and thus are unregistered and trailered to sanctioned race events. It hurts our race industry when people put their race cars on the road knowingly violating EPA federal laws.
Before we perform any work on an off-road/race-only vehicle, we require the Leroy Engineering Emissions Statement Acknowledgement Form to be signed to ensure that the vehicle is not registered in any state.
Leroy Engineering is not allowed by law to sell products or services that tamper with emission control systems in street-legal cars driven on public roadways. We work with the Ohio EPA's Northeast District Office of Compliance Assistance and Pollution Prevention (OCAPP) to ensure that we align with the law.
