Design
IDOT staff and/or consultants are responsible for designing the Erosion and Sediment Control plan for a project. This plan typically uses a variety of Best Management Practices (BMPs) to control erosion and sediment at a project. In addition, a storm water Pollution Prevention Plan (SWPPP) is prepared, submitted to the IEPA, and kept at the project site. The SWPPP describes the project site conditions, what controls and practices are to be followed, as well as a contractor certification statement. The guidance used to design the Erosion and Control Plan and SWPPP is in Chapter 41 of the IDOT BDE Manual.
