Certain violations - such as not having a grease interceptor - carry a minimum fine of $2,000. As the waste stream flows through the orifice in the flow control device negative pressure is created, drawing in air from the air intake which is intended to mix with the waste water as it enters the grease interceptor aiding in separation efficiency. %PDF-1.5 %
