(A) Effective storm water pollution prevention on construction sites is dependent on a combination of preventing movement of soil from its original position (erosion control), intercepting displaced soil prior to entering a waterbody (sediment control), and proper on-site materials handling.
(B) For land disturbance of one acre or more, the developer must submit to the Department a SWPPP with detailed erosion and sediment control plans as well as a narrative describing materials handling and storage, and construction sequencing. The SWPPP and the project management log must be retained for at least three years from the date the project permit is terminated. For land disturbances totaling 10,000 square feet or more but less than one acre, appropriate erosion and sediment control measures that are consistent with the City of Decatur Storm Water Technical Standards Manual must be designed and shown on the plans.
(C) The required IDEM general and implementation requirements that apply to all land-disturbing activities are contained in the City of Decatur Storm Water Technical Standards Manual.
