Federal Clean Water Act regulations require stormwater discharges from construction activities that disturb one or more acres of land and/or are part of a larger common plan of development to be covered under a National Pollutant Discharge Elimination System (NPDES) permit. When designing a project that falls under one of those categories or occurs within an area that is currently covered by an existing NPDES permit, a Stormwater Pollution Prevention Plan (SWPPP) is required.
Our engineers and SWPPP designers will establish a comprehensive plan for existing and post-construction conditions of the site to identify potential sources of pollution. Additionally, a description will be provided of the implementation and management of practices to be used to reduce the pollutants in stormwater discharge.
Erosion and sediment control management infractions can levy large fines from the Department of Natural Resources (DNR) and/or the Environmental Protection Agency (EPA). Providing a plan that includes protective cover on the soil surface, best management practices (BMP’s) to retain and filter sediment, and proper runoff diversion maximizes soil infiltration and captures sediment. Having a compliant, current, and effective SWPPP plan helps mitigate potential problems before construction begins.
