Sediment is the biggest pollutant associated with construction site storm water runoff. Uncontrolled storm water runoff from construction sites can significantly impact rivers, lakes and estuaries because the sediment can reduce the amount of sunlight reaching aquatic plants, clog fish gills, smother aquatic habitat and spawning areas, and impede navigation. Construction sites that disturb one acre or more of land must apply for and be issued a notice of coverage from the Tennessee Department of Environment and Conservation (TDEC) before any work can begin.
If you are applying for a Land Disturbance Permit from the City of Portland and the entrance to the property is on state highway right-of-way, you must provide a copy of an entrance permit from TDOT. A copy of the TDOT permit must be uploaded to the IDT portal. City land disturbance and building permits WILL NOT be issued until TDOT has approved the entrance and a copy has been provided. More information about TDOT Highway Entrance permits can be found at the following link. Highway Entrance Permits (tn.gov)
