Commercial Users

The Wastewater Treatment Plant in American Canyon requires certain commercial businesses discharging wastewater to the City's sanitary sewer to apply for and maintain a Commercial Business Wastewater Discharge Permit.  Environmental Compliance staff at the wastewater treatment plant regularly inspect permitted commercial industrial businesses to ensure that proper business practices are being followed and protect the City's sanitary sewer system as well as the wastewater treatment plant.  This is necessary in order to comply with requirements from the California Regional Water Quality Control Board.

Significant Industrial Users

Significant Industrial Users (SIU's), as defined by the Code of Federal Regulations, are any industrial user of the the City's wastewater disposal system who contribute significant amount of wastewater or pollutants to the wastewater treatment plant or have a reasonable potential for adversely affecting the wastewater treatment plant's operation.

Groundwater Dischargers

All Groundwater Cleanup Procedures operating within the City of American Canyon are required to apply for and obtain a Groundwater Discharge Permit prior to any discharge to the City's sanitary sewer system.

Local Limits

Local Limits comprise a partial list of toxic pollutants of concern and their maximum concentration by any discharger for admission into the sewerage system.

Enforcement Response Plan (ERP)

The purpose of the ERP is to provide consistent enforcement responses for similar violations and circumstances. The ERP outlines the procedures that will be used to identify, document, track and respond to noncompliance. The ERP also provides guidance for selecting the enforcement action most appropriate for a given violation.

Zero-Dischargers

A Zero-Discharge Industry is one whose facility only discharges sanitary sewage, or domestic waste, to the City’s wastewater system. The Environmental Compliance Group will determine whether an industry is required to apply for and maintain a Zero-Discharge Permit based on waste characteristics and reasonable potential for adversely affecting the wastewater treatment plant’s operation should waste be accidentally discharged to the sanitary sewer.
