Purpose: “The purpose of the Illicit Discharge Detection and Elimination (IDDE) ordinance is to provide for the health, safety, and general welfare of the citizens of Rye through the regulation of non-storm water discharges to the storm drainage system to the maximum extent practicable as required by federal and state law. The IDDE ordinance establishes methods for controlling the introduction of pollutants into the municipal separate storm sewer system (MS4) in order to comply with requirements of the National Pollutant Discharge Elimination System (NPDES) permit process.”
