In 1983, the Bureau of Water Supply became the Department of Environmental Protection and the New York State Legislature revised the Criminal Procedure Law, part of the New York State Laws, to include DEP police officers. In 1999, the DEP jurisdiction was extended to include the five boroughs of New York City. In 2004, the highest court in the state, the New York State Court of Appeals, affirmed the DEP Police Department's jurisdiction throughout the watershed. Members of the DEP Police are New York City police officers. The term Environmental Protection Police does not include NYC Environmental Police Officers that are assigned to the NYC Sanitation Department (DSNY). These Officers are similar to Sanitation Peace Officers.
