Vehicle emissions defeat devices: Steer clear!
The Environmental Protection Agency (EPA) regulates emissions from motor vehicles, engines, and the fuels used to operate them. The agency requires vehicle manufacturers to install control devices that limit the amount of air pollutants a vehicle may emit. However, defeat devices attempt to detour around these controls and allow emissions beyond federal limits.
Excess vehicle emissions can threaten the health of others, impair state and local efforts to maintain national air quality standards, and — as one company and its owner learned — subject you and your business to steep monetary penalties.
Steer clear of defeat devices to ensure a smooth regulatory road.
Company learns multimillion-dollar lesson
EPA and the U.S. Department of Justice reached a settlement agreement with a North Carolina automotive parts company and its owner for violating the Clean Air Act (CAA) requirements for mobile sources by:
- Manufacturing, selling, and installing more than 250,000 defeat devices on diesel pickup trucks; and
- Installing aftermarket defeat devices on hundreds of diesel pickup trucks.
The company and its owner face civil and criminal consequences and will pay a total of $10 million in fees and penalties.
Civil enforcement
A July 2024 consent decree (pending court approval) requires both parties to pay a combined $7 million penalty. It also bans the company and owner from:
- Manufacturing, selling, offering to sell, and installing defeat devices;
- Transferring intellectual property to help others make or sell defeat devices; and
- Investing in or profiting from other businesses’ defeat devices.
Criminal enforcement
Both the company and owner pleaded guilty to conspiring to violate the CAA. The federal court ordered the company to pay a $2.4 million fine and complete three years of organizational probation. It also ordered the owner to pay a $600,000 fine and serve three years of probation.
What are defeat devices?
A defeat device is any component that “bypasses, impairs, defeats, or disables the control of emissions of any regulated pollutant” (40 CFR 1068.101(b)(2)). Put simply, it’s an illegal device that removes or disables a vehicle’s emissions controls.
There are generally two types of defeat devices: hardware (such as modified automotive parts) and software (like delete tuners). In fact, many of the devices consist of both types that work in tandem. Federal law (and EPA regulations at 1068.101(b)) bans defeat devices used to swerve around vehicle emissions controls. Section 203(a)(3) of the CAA prohibits anyone from:
- Tampering with an EPA-certified vehicle’s emissions control devices to remove them or make them inoperative before selling the vehicle,
- Knowingly tampering with an EPA-certified vehicle’s emissions control devices to remove them or make them inoperative after the vehicle is sold and delivered to the purchaser, and
- Knowingly manufacturing, selling, offering to sell, or installing defeat devices that bypass, defeat, or render inoperative any emission control device.
Common emission control devices include:
- Onboard diagnostic systems,
- Catalytic converters,
- Electronic control units,
- Fuel systems, and
- Diesel particulate filters.
Who do the regulations affect?
The prohibition on defeat devices applies to everyone, from the original equipment manufacturer that installs the vehicle emissions controls to the vehicle owner and operators.
The 1990 CAA Amendments expanded the tampering provision in Section 203(a)(3) to include “any person.” Further, EPA’s regulations at 1068.101(b) “apply to everyone,” such as:
- Vehicle manufacturers;
- Vehicle dealers;
- Automobile repair shops;
- Commercial mechanics;
- Fleet operators;
- Aftermarket automotive part manufacturers, sellers, and installers;
- Owners; and
- Operators.
Compliance tips
Consider these helpful suggestions for maintaining compliance:
- Check and comply with your state and local regulations, as they may be more stringent than federal requirements and impose additional rules. For example, states may require certified technicians to conduct automotive maintenance services on emission controls. States may also prohibit operating, selling, and/or registering tampered vehicles.
- Purchase aftermarket automotive parts only from reputable sources. Obtain proof that the aftermarket parts won’t increase emissions.
- Self-disclose any potential violations you find to EPA and/or the state environmental agency. EPA and many states will lower or waive civil penalties for self-reporting violations.
The case against this automotive parts company and owner serves as a multimillion-dollar reminder about making, selling, installing, or using defeat devices — steer clear!
Key to remember: Steer clear of defeat devices that try to detour around EPA’s vehicle emissions controls to ensure a smooth regulatory road.
