DWQ issued two Draft NJPDES Combined Sewer Overflow (CSO) permits on Tuesday, May 9, 2023 to the City of Elizabeth and to the Joint Meeting of Essex & Union Counties. These permits serve to improve water quality in these urban areas by requiring the reduction of combined sewer discharges. These updated CSO Permits expand upon the public engagement found in the 2015 CSO Permits and reflect the Long-Term Control Plan submitted by North Hudson Sewerage Authority Adams Street and River Road Wastewater Treatment Plants.

The goal of the CSO permits is to meet the requirements of the Clean Water Act and the National CSO Policy by reducing or eliminating the remaining CSO discharges in New Jersey. The Department is committed to working with Combined Sewer Overflow (CSO) permittees and CSO communities to reduce or eliminate CSOs by providing low-cost funding and guidance to meet permit obligations. In order to achieve the reduction or elimination of CSO discharges, CSO permittees will need to reduce flooding, ensure proper operation, maintenance and management of existing infrastructure and provide opportunities for green infrastructure. CSO permits reinforce the importance of properly operated and maintained water infrastructure systems in protecting public health and the environment and supporting economic redevelopment.

CSO Permits 2015

Twenty-five (25) individual CSO permits, covering 21 municipalities and effective on July 1, 2015, encourage permittee and community engagement on the planning and development of projects. CSO projects provide urban redevelopment opportunities, improve water quality, beautify neighborhoods, and improve the overall quality of life in our urban communities.

A major emphasis of the 2015 permit process was the development of regional strategies to reduce the amount of storm water that flows into combined sewer systems, through the development and implementation of a Long Term Control Plan. These LTCPs are now being incorporated into the next round of NJPDES CSO permits.
