Dayton, OH – Corporate negligence and individual misconduct led to criminal charges and penalties for DDP, Inc., the owner of several Grease Monkey quick oil change franchises, and two of its employees in 2004. The case, investigated by the Environmental Protection Agency (EPA) and adjudicated in federal court, revealed a pattern of illegal wastewater discharge into the Dayton, Ohio sewer system.
According to court documents, the Grease Monkey facilities generated petroleum-contaminated wastewater as a byproduct of oil change services. This wastewater was channeled to an oil-water separator, ostensibly to remove some contaminants. However, rather than properly disposing of the remaining oily discharge, DDP, Inc. knowingly directed it into the city’s sanitary sewer without obtaining the necessary permits. This practice violated the Clean Water Act, designed to protect the nation’s waterways from pollution.
The legal proceedings began on February 12, 2003, with DDP, Inc. charged with a knowing violation of 33 U.S.C. 1319(c)(2)(A) of the Clean Water Act. Simultaneously, Robert M. Manley, a store manager, faced charges for negligently violating 33 U.S.C. 1319(c)(1)(A). The EPA’s investigation uncovered evidence suggesting a deliberate disregard for environmental regulations and a failure to implement adequate waste management practices.
In July 2003, DDP, Inc. entered a guilty plea and received a sentence of 24 months probation. As part of the sentencing, the company was ordered to pay $3,535 in restitution to both the Ohio EPA and the City of Dayton, covering costs associated with the illegal discharge and subsequent cleanup efforts. Manley also pled guilty and was sentenced to 12 months probation. The case didn’t end there, however. Further investigation led to charges against Dennis Henman, a district manager for DDP, in March 2004.
Henman was charged with knowingly violating 33 U.S.C. 1319(c)(2)(A), mirroring the initial charge against the corporation. He too entered a guilty plea on July 30, 2004, receiving a 36-month probationary sentence, though no fines were imposed. The relatively lenient sentence for Henman, compared to the restitution levied against the corporation, has raised questions among environmental advocacy groups about the effectiveness of individual accountability in corporate environmental crimes.
