EMISSIONS

EPA States Emissions Tampering Is Rampant

A recent report from the Air Enforcement Division (AED) of the Environmental Protection Agency (EPA) has found that the emission control systems of more than 550,000 Class 2B and Class 3 diesel trucks have been tampered with. The findings stem from investigations conducted over approximately five years’ time by the EPA’S civil enforcement personnel. State and county level results included in the report also reveal that emissions-off calibration files (also known as “delete tuning”) from more than 150,000 unique invoices cover sales in all 50 states and approximately 83-percent of all U.S. counties. In fiscal year 2020, the EPA resolved some 31 civil emission tampering and aftermarket defeat device cases that prevented more motor vehicle emissions than in any prior year in the agency’s history.
