If your business uses 25,000 gallons or more of water per day to produce a product OR your business engages in the production of any product that may result in the discharge of the following pollutants/contaminants, you are required to apply for a Waste Discharge Authorization Permit:

Pollutants which will cause corrosive structural damage to the sanitary sewer system with a pH lower than 5.0
Solid or viscous pollutants in amounts which will cause obstruction to the flow in the sanitary sewer system resulting in interference (such as fats, oils, grease)
Any pollutant, including oxygen demanding pollutants discharged at a flow rate and/or pollutant concentration which will cause interference with the sanitary sewer system
High temperature discharges exceeding 104 °F/40 °C which inhibit biological activity in the sanitary sewer system
Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through
Pollutants which result in the presence of toxic gases, vapors, or fumes within the sanitary sewer system
