El Cajon, CA – American Metal Processing, Inc. (AMP), a now-defunct metal plating business, was slapped with federal penalties in 2007 after illegally dumping hazardous waste directly into the city’s sewer system. The scheme, discovered by environmental regulators, involved diverting highly toxic plating waste—a byproduct of the metal finishing process—through the company’s toilet drains, bypassing established wastewater treatment protocols.
The Environmental Protection Agency’s (EPA) criminal enforcement investigation revealed that AMP deliberately shut down its designated waste treatment systems associated with the plating operation. Rather than properly disposing of the toxic effluent, company officials opted for the clandestine and unlawful method of flushing the waste into the municipal sewer, a blatant disregard for both environmental regulations and public health. The decision to use toilet drains was reportedly an attempt to conceal the illegal discharges and avoid detection.
Federal prosecutors charged AMP and a key figure, identified as Cummings, with violating the Clean Water Act (CWA). The charges specifically cited 33 U.S.C. 1319(c)(2)(A), which addresses knowingly violating permit requirements, and 33 U.S.C. 1311(a), relating to the prohibition of discharges of pollutants into navigable waters without a permit. The indictment alleged that AMP knowingly operated a source in violation of an approved pretreatment program permit, a critical component of protecting wastewater treatment facilities from harmful pollutants.
In December 2005, both the company and Cummings entered guilty pleas to the federal charges. The case proceeded to sentencing in March 2007. American Metal Processing was sentenced to a period of five years probation, and ordered to remit a $50,000 federal fine, alongside $400 in special assessment fees. Cummings, personally held accountable for the environmental crime, received a three-month prison sentence, followed by two years of probation, and was assessed a $5,000 fine and $100 special assessment.
The case underscores the EPA’s commitment to pursuing criminal charges against companies and individuals who prioritize profit over environmental compliance. Illegal discharges of industrial waste can severely damage aquatic ecosystems, threaten drinking water supplies, and pose significant risks to public health. While AMP is no longer in operation, the case serves as a cautionary tale for other businesses operating in regulated industries.
