Description: This data set was developed in connection with SPDES Permit NY-0287890 and contains known outfalls to which the New York City Municipal Separate Storm Sewer System (MS4) drains. An MS4 outfall is any point where a separate storm sewer system owned or operated by the City of New York discharges to Surface Waters of the State or to another MS4 (an MS4 owned or operated by another regulated entity). Outfalls include discharges from pipes, ditches, swales, and other points of concentrated flow. However, areas of non-concentrated (sheet) flow which drain to Surface Waters of the State or an MS4 owned or operated by an entity other than the City are not considered MS4 outfalls. This data set represents available GIS data as of August 1, 2020. This data set includes outfall ID, outfall type, waterbody to which the outfall drains, and the pollutants of concern identified for that waterbody. The boundaries for Surface Waters of the State are from a data set provided by NYSDEC (http://gis.ny.gov/gisdata/inventories/details.cfm?DSID=1117) and the pollutants of concern are from Appendix 2 of SPDES Permit NY-0287890. New York City has on-going efforts to map the MS4.
