Commercial Wastewater Discharge

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)(PDF, 3MB)
The purpose of the Enforcement Response Plan (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.

Commercial Users

The Water Reclamation Facility 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 Water Reclamation Facility 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 Water Reclamation Facility. This is necessary in order to comply with requirements from the California Regional Water Quality Control Board.

Restaurants

Fats, oils and grease (FOG) discharged from food service establishments are a cause of sewer line blockages. In order to prevent sewer overflows, the City of American Canyon has implemented a program to prevent excessive discharge of FOG from food service establishments.

Medical Facilities

Wastewater discharged from medical facilities can contribute a wide variety of toxic compounds to the sewer system. Metals such as mercury and zinc are just a few pollutants that are commonly contributed to wastewater by medical facilities. The Water Reclamation Facility must regulate and monitor the concentrations of these metals in order to maintain effective treatment.

Car Washes

Wastewater discharged from car wash facilities can contribute a wide variety of toxic compounds to the sewer system. Metals such as copper, mercury, nickel, and zinc are just a few pollutants that are commonly contributed to wastewater by car wash facilities. The Water Reclamation Facility must regulate and monitor the concentrations of these metals in order to maintain effective treatment.

Auto Repair Shops

Wastewater discharged from auto repair shops can contribute a wide variety of toxic compounds to the sewer system. Metals such as copper, mercury, nickel, and zinc are just a few pollutants that are commonly contributed to wastewater by auto repair shops. The Water Reclamation Facility must regulate and monitor the concentrations of these metals in order to maintain effective treatment.

Dental Offices

Beneficial uses of San Francisco Bay are impaired due to high levels of mercury in fish, water and sediment. As a result, strict limitations on mercury discharge have been placed on all Water Reclamation Facilities in the Bay Area. In order to meet these requirements the City must respond by establishing a strong public education and outreach program, as well as a permitting process for businesses that could be categorized as sources of mercury contribution in wastewater.

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 Water Reclamation Facility or have a reasonable potential for adversely affecting the Water Reclamation Facility's operation.

All Significant Industrial Users are required to apply for and maintain a SIU Wastewater Discharge Permit.

Temporary Dischargers

Temporary Wastewater Discharge Permits are issued for all short-term projects that discharge into the City’s sewer system. The type of discharge may vary and could include, for example, process wastewater or groundwater. Permit applications require a minimum of 30 days for processing

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 Water Reclamation Facility’s operation should waste be accidentally discharged to the sanitary sewer.
