The City of Redmond's Spill Response or Illicit Discharge Detection and Elimination (IDDE) Program is a key component of Redmond's National Pollutant Discharge Elimination System (NPDES) Phase II Municipal Stormwater Permit.
The program focuses on investigation and response to activities or incidents that could result in the discharge of pollutants to storm drains and the environment, including elimination of improper drain line connections and contamination issues from sanitary sewer lines or private septic systems.
The goal of IDDE is to reduce the amount of stormwater pollution reaching streams, groundwater, Lake Sammamish, and any of Redmond's creeks from stormwater drainage systems.
