IDOT is actively involved in assuring compliance of NPDES requirements for state highway projects. We feel one of the best ways to do this is educating its staff, consultants and contractors. This is why we have regularly scheduled classes on NPDES requirements through the Illinois Center for Transportation (ICT).
