|Combined Sewer Overflow
The Department is committed to working with Combined Sewer Overflow (CSO) permittees and CSO communities to reduce or eliminate CSOs. The Department will assist permittees in meeting their permit obligations by providing technical assistance, guidance, and training.
The individual CSO permits encourage permittee and community collaboration on the planning and development of projects that will provide urban redevelopment opportunities, improve water quality, beautify neighborhoods, and improve the overall quality of life in our urban communities.
The permittees are required to develop long term control plans to address the remaining 217 combined sewer overflow (CSO) discharge points, or outfalls, in the state. These permits also reinforce the importance of properly operated and maintained water infrastructure systems in protecting public health and the environment and supporting economic redevelopment.
Through the work under the previous general permits, the total number of CSO outfalls in New Jersey was reduced from 281 to 217. The elimination of 64 CSO outfalls accounts for a more than 20% reduction in CSO outfalls. Additionally, solids and floatables controls have been installed at nearly every CSO outfall to prevent solids that are greater than one half inch from entering the waterway.
The individual permits build upon the previous general permit requirements and permittees should consider what work has already been performed and how past achievements may be incorporated into new efforts to satisfy the new individual CSO permit requirements.
