U.S. EPA Clean Air Act enforcement action resolved in fiscal year 2024.
About this enforcement action
Settlement for alleged Clean Air Act violations involving aftermarket parts/services that defeat or tamper with vehicle emissions controls.
Regulatory context — Aftermarket cases
Aftermarket cases involve the manufacture, sale, or installation of products that bypass, defeat, or remove a vehicle's emission control systems — defeat devices, EGR delete kits, DPF delete tunes, catless exhausts sold without the required disclosures, and similar components. The U.S. EPA enforces against aftermarket parts and tune sellers under Section 203(a)(3)(B) of the Clean Air Act, 42 U.S.C. § 7522(a)(3)(B), which prohibits the manufacture and sale of defeat devices for use in motor vehicles. Civil penalties are assessed per noncompliant part or installation; the statutory maximum was $4,876 per violation at the time most of these settlements resolved.
