Charlotte, NC – Matthew Sidney Geouge was sentenced to over one year in federal prison this June for his role in a multi-million dollar scheme to manufacture and distribute devices designed to bypass vehicle emissions controls, violating federal environmental regulations and evading taxes. The case, investigated by the Environmental Protection Agency (EPA) and the Internal Revenue Service (IRS), reveals a sophisticated conspiracy that flooded the market with illegal “tuners” and resulted in significant air pollution.
According to court documents, Geouge began developing specialized software – dubbed “tunes” – in 2008 for devices that could defeat the emissions controls on vehicles. These tuners, while boosting engine power, effectively disabled critical pollution reduction systems. In 2012, Geouge’s activities became further entrenched when he began working with, and later partnered with, individuals who owned a company manufacturing the tuner hardware. Together, the group established additional companies to distribute the tuned devices, ultimately selling over 14,000 units.
The EPA initially flagged the illegal activity in 2015, issuing a notice of violation to Geouge. However, rather than complying, Geouge allegedly continued to manufacture, sell, and service the illegal devices. The scheme was further complicated by attempts to conceal income earned from the sales, with funds diverted to another individual to avoid paying penalties to the EPA and taxes to the IRS. This deliberate evasion of financial obligations added another layer of criminality to the already serious environmental violations.
Legal Ramifications
Geouge was sentenced on June 23rd, 2022, in the Western District of North Carolina to one year and one day in prison for conspiracy to violate the Clean Air Act. He faces three years of supervised release, with the first six months to be served under home confinement. The court also ordered Geouge to pay a substantial $1.3 million civil penalty to the EPA and $1.2 million in restitution to the IRS. The charges stemmed from violations of 18 U.S.C. 371 (Conspiracy), 26 U.S.C. 7201 (Tax Evasion), and 42 U.S.C. 7413(c)(2)(C) (Tampering with Emission Control Devices). His co-conspirators have already been sentenced for their respective roles in the illegal operation.
Growing Trend of Emissions Defeat Devices
This case highlights a growing concern for environmental regulators: the proliferation of aftermarket devices designed to circumvent emissions standards. These “defeat devices” not only contribute to increased air pollution but also undermine the effectiveness of regulations aimed at protecting public health and the environment. The EPA continues to aggressively pursue enforcement actions against manufacturers, distributors, and installers of these illegal products.
