ResponsibilitiesThe Pretreatment Program administers local, state and federal regulations affecting area businesses and the quality of the wastewater discharged into wastewater treatment system. These regulations were implemented:
- To prevent the introduction of pollutants into the municipal wastewater system which will interfere with the operation of the system or contaminate the resulting sludge;
- To prevent the introduction of pollutants into the municipal wastewater system which will pass through the wastewater system, inadequately treated, into any waters of the State or otherwise be incompatible with the system;
- To promote reuse and recycling of wastewater and sludge from the municipal system;
- To protect both municipal personnel who may be affected by sewage, sludge, and effluent in the course of their employment as well as protecting the general public;
- To provide for equitable distribution of the cost of construction, operation, maintenance and improvement of the municipal wastewater system;
- To ensure that the municipality complies with its NPDES permit conditions, sludge use and disposal requirements and any other federal or state laws to which the municipal wastewater system is subject.
