More Information
Commercial & Industry Requirements
Any business that discharges wastewater to the City sewer that contains heavy metals, petroleum products, volatile organics, food-product grease, or any other material that could affect the wastewater treatment plant is required to comply with the Pretreatment Program. Such businesses are termed "Industrial or Commercial Users" and must complete a Business Information Form and/or an Industrial Waste Survey upon request of the Pretreatment Coordinator. The form and survey provide information on business process operations and wastewater characteristics and is the basis for determining the business' status in the Pretreatment Program.

Discharge Permits
Some businesses also may be required to obtain a permit to discharge wastewater to the sewer system if the business meets any one of the following criteria:
  1. The business is subject to Federal categorical standards.
  2. The business discharges > 25,000 gallons of wastewater per day.
  3. The business contributes 5% or more of the average hydraulic or organic capacity of the wastewater plant.
  4. The business' wastewater has the potential to significantly impact the collection system or wastewater plant or for violating any pretreatment standard or requirement.

Pollution Prevention
Pollution Prevention (P2) is the reduction or elimination of pollution at the source of generation instead of at the end of a process. P2 avoids the generation of waste and harmful substances. It is any practice that stops pollution before it is created.

What is the Significance of P2 to the Pretreatment Program?
Successful P2 makes compliance with environmental regulatory programs such as the Pretreatment Program easier and less costly. The Pretreatment Program regulates wastewater pollutants. P2 can help businesses avoid generating wastewater pollutants.
