In the future, Combined Sewer Overflow (CSO) communities will be required to apply for and maintain NPDES permits. As a result, communities will also be required to implement what EPA has identified as the nine minimum controls and a long term CSO control plan.
Proper operation and maintenance of sewer systems and treatment plans...Modified operations and maintenance programs may result in significant, low cost improvements.
Maximum use of collection system for storage...Storage of quantities of combined storm and sanitary sewage during wet weather periods.
Review and modify pretreatment program...Industrial and other pollutant loading may be lessened by implementing more efficient programs.
Maximization of flow to POTW (ALCOSAN) for treatment...Can more flow through existing facilities rather than discharging to rivers.
Prohibit CSO discharges during dry weather...Continue to ensure the elimination of all dry weather CSO discharges.
Control solids and floatables...If we keep them off the streets, we won't see them on our rivers.
Pollution prevention and Public Notification...Through better education programs we can alert system users to the serious consequences of dumping household hazardous materials and waste oils into the sewers, catch basins, etc.
Characterize CSO discharges and their effects.
