NPDES permits for the two City of Columbus wastewater treatment plants expire in 2010, and there has been pressure from many interested parties to implement more stringent nutrient limits. In order for the City to take a proactive approach, a Qual2K model was developed to examine the chemical water quality effects that the City's two wastewater treatment plants have on the Scioto River. The purpose of the model is to predict how changes in possible future permit limits will affect the attainment of assigned water quality designations of the Scioto River.

The model demonstrates that assimilation capacity of the Scioto River will not be taxed with increased plant flows and changing effluent loads. It is estimated that even with the extensive expansion of the City's wastewater treatment plants to meet peak flow goals, the Scioto River can assimilate the load and maintain full attainment of the warmwater habitat use designation.
