Construction Site Program

Construction activities (which include earth change activities such as clearing, grading, excavating, stockpiling, etc.) that disturb one or more acres, are regulated under the under Michigan's NPDES construction storm water program. Landowners of regulated construction sites are required to obtain Soil Erosion and Sedimentation Control (SESC) permits from the county or municipal enforcing agency or the work must be conducted by an Authorized Public Agency.   Earth change activities that disturb 1 to 5 acres are deemed to have automatic construction storm water coverage once the SESC permit coverage is obtained.  Earth change activities that disturb greater than 5 acres must file a Notice of Coverage with the DEQ including a copy of the SESC permit, a location map and a copy of the approved Soil Erosion and Sedimentation Control Plan for the Project, the name and certification of the certified construction storm water operator, and the filing fee.  Once the SESC permit is in place and the respective storm water coverage is obtained, the landowner must ensure that the site is inspected by a certified construction storm water operator once per week, and within 24 hours after every precipitation event that results in a discharge from the site and ensure that any needed corrective actions are carried out.
