ASP Plating Company — Criminal Zinc Wastewater Discharge into County Sewer, Michigan (2023)
Outcome: ASP Plating Company, owner Gary Stephen Rowe, and his son Stephen Frederick Rowe were sentenced for criminal Clean Water Act violations after repeatedly and illegally discharging zinc-containing wastewater from the metal plating operation into the county sanitary sewer system, bypassing required industrial pretreatment standards designed to protect the receiving municipal wastewater treatment plant.
ASP Plating Company operated a metal electroplating facility in western Michigan that used zinc and other heavy metals in its plating processes, generating process wastewater with high concentrations of heavy metals. Metal plating operations discharging to a publicly owned treatment works (POTW) are subject to Clean Water Act industrial pretreatment standards requiring removal of heavy metals to levels the municipal treatment plant can accept without interference or pass-through of contaminants to the plant's effluent or biosolids.
The company, along with its owner Gary Stephen Rowe and his son, repeatedly and illegally discharged zinc-containing wastewater directly to the county sewer system without conducting required pretreatment to reduce zinc concentrations to permissible limits. The discharges violated the facility's industrial pretreatment permit and Clean Water Act pretreatment standards. The pattern of repeated violations — characterized by EPA and DOJ as deliberate circumvention of pretreatment requirements — triggered criminal prosecution under the Clean Water Act's knowing endangerment provisions.
Sentencing occurred February 17, 2023. Metal plating operations are a common source of heavy metal contamination in municipal wastewater systems; zinc, copper, nickel, and chromium from plating operations can accumulate in municipal biosolids at concentrations that limit agricultural land application uses and can interfere with biological treatment processes at municipal plants.

How Crucible Prevents This
Metal plating operations generate wastewater with high concentrations of heavy metals that must be pretreated before discharge to a municipal sewer under Clean Water Act industrial pretreatment standards. The criminal discharge pattern at ASP Plating — repeated illegal discharges by both company and individual owners — reflects a deliberate decision to bypass required pretreatment rather than an operational oversight. Crucible's instinct-observer hook documenting management decisions around pretreatment system operation creates a record that surfaces the deliberate nature of bypass decisions before they accumulate to criminal exposure.
