Oregon Transport Company and its Owner Found Guilty of Tampering with Clean Air Act Monitoring Devices

An Oregon transport company violated the Clean Air Act when it intentionally and with knowledge tampered with emissions monitoring devices.

Clancy Logistics, Inc., of Fairview, and its owner, Timothy Curtis Clancy (55) of Sherwood, were each sentenced yesterday to three years probation and a joint fine of $101,510.

Clancy Deleted Emission Control Systems on 13 Company Trucks

The incidents occurred between October 2019 and July 2023, according to court documents. During that time, Clancy tampered with monitoring devices when he deleted and tuned emission control systems of at least 13 of his company’s diesel semi-trailer trucks.

The court heard that Clancy oversaw the illegal modification of the vehicles, including instructing employees to remove emission control equipment and to tune onboard diagnostic systems so that the removal of control equipment could no longer be detected. The company then knowingly proceeded to operate the modified vehicles.

Clancy and Clancy Logistics were charged with criminal information and two counts of Clean Air Act tampering on 13 September 2024. Five days later, both parties entered guilty pleas to one count of tampering with a monitoring device.

The Environmental Protection Agency’s Criminal Investigation Division investigated the case, which was prosecuted by Andrew Ho, Assistant U.S. Attorney for the District of Oregon, and Gwendolyn Russell, Special Assistant U.S. Attorney for the Environmental Protection Agency.
