The removal of emission control devices from diesel-powered vehicles, an act often referred to with specific phrasing, is currently illegal under federal law in the United States. These devices, such as diesel particulate filters (DPFs) and selective catalytic reduction (SCR) systems, are mandated to minimize harmful pollutants released into the atmosphere. Tampering with or removing these components results in increased emissions of particulate matter, nitrogen oxides, and other pollutants. For example, removing a DPF significantly increases particulate matter emissions, contributing to respiratory problems and reduced air quality.

Enforcement of these regulations falls under the jurisdiction of the Environmental Protection Agency (EPA). The agency’s focus on preventing the disabling of emissions controls stems from the significant public health and environmental benefits derived from their proper functioning. Historically, the implementation of stricter emissions standards has demonstrably improved air quality in urban areas and reduced the incidence of respiratory illnesses. The EPA estimates that continued adherence to these standards will prevent thousands of premature deaths annually. Moreover, a well-maintained emissions system ensures that vehicles meet the standards under which they were certified, contributing to a level playing field for manufacturers and consumers.
