Cheating emission controls gains focus
In late 2020, EPA issued an Enforcement Alert bringing extra attention to vehicle emission control modifications. The installation of defeat devices and tampering with emission equipment is not a new issue that the agency is trying to tackle; the concern is over continued and growing non-compliance. EPA points out that they have closed more than 70 related enforcement cases in the last five years. Some of those have come with hefty monetary penalties, including one in 2019 for $1,100,000 — and penalty severity has only increased since. Just over a year ago, in January 2020, an increased civil penalty of $4,819 per defeat device took effect.
The Alert points out that EPA has named “Stopping Aftermarket Defeat Devices for Vehicles and Engines” as a National Compliance Initiative (NCI) focusing on aftermarket parts manufacturers, sales, and installation. This expands the focus of the program, which had emphasized vehicle manufacturers only. The current NCI list includes only six priorities, bringing significantly more attention to these high-profile issues.
Mobile sources are a significant contributor of air pollution and with EPA’s direct authority for their regulation, it makes sense that the federal agency is taking action. As stated on the NCI program webpage, “Illegally-modified vehicles and engines contribute substantial excess pollution that harms public health and impedes efforts by the EPA, tribes, states, and local agencies to plan for and attain air quality standards.”
Actions such as the Enforcement Alert and NCI listing show that we can expect to see more resources directed toward reigning in these elevated emissions and make progress toward improved air quality.
