Riverside, CA – A Riverside smog check station owner has been sentenced following a year-long investigation into fraudulent emissions testing practices. Phi-Long Huynh Nguyen, owner of PL Test Only Center, pled guilty to falsifying smog certificates, defrauding the state of California and potentially allowing polluting vehicles to remain on the road.
The case originated from an anonymous tip received by the EPA’s Criminal Investigation Division (EPA-CID) in March 2012. The informant alleged that Nguyen was engaged in “clean piping,” a scheme where technicians manipulate emissions testing equipment by inputting data for a compliant vehicle while actually testing a vehicle known to fail. The tip specifically identified a Toyota Camry, owned by Nguyen, as the “clean” vehicle used to generate the fraudulent certificates.
Investigators with the EPA-CID’s Los Angeles Area Office quickly moved to investigate the claims. The investigation confirmed the allegations, revealing a systematic effort to bypass California’s stringent emissions standards. By using the Camry to generate passing results, Nguyen was able to issue valid smog certificates for vehicles that would otherwise have failed inspection, effectively deceiving the California Bureau of Automotive Repair and potentially circumventing environmental regulations.
Legal Ramifications
On July 10, 2012, Nguyen was formally charged with violating California Vehicle Code Section 4463(a)(1), which specifically prohibits the willful and unlawful alteration, forgery, or falsification of smog check certificates with the intent to defraud. The charge carries significant penalties, reflecting the state’s commitment to maintaining air quality and enforcing regulations within the automotive repair industry.
Sentencing & Restitution
Following the guilty plea on December 14, 2012, Nguyen received a sentence of 20 days incarceration, with credit given for two days already served. He was also placed on 36 months of probation and ordered to pay a $240 fine. Furthermore, Nguyen was mandated to provide $7,561 in restitution to the California Bureau of Automotive Repair to cover the costs associated with the investigation and the impact of the fraudulent activity.
Industry Ban & Seized Equipment
The court also ordered the forfeiture of all evidence seized during the investigation, including critical smog testing equipment and the computer used to manipulate the test results. Most significantly, Nguyen is prohibited from engaging in any automotive repair or smog testing activities for the duration of his probation period, effectively barring him from the industry. This measure aims to prevent further violations and protect consumers from similar fraudulent practices.
