When it rains, stormwater washes over the loose soil on a construction site, along with various materials and products being stored outside. As stormwater flows over the site, it can pick up pollutants like sediment, debris, and chemicals from that loose soil and transport them to nearby storm sewer systems or directly into rivers, lakes, or coastal waters. EPA works with construction site operators to make sure they have the proper stormwater controls in place so that construction can proceed in a way that protects your community’s clean water and the surrounding environment.
Why are the Definitions of Disturbed and Impermeable So Important?
We hope this sheds some light on storm water permitting. Don’t hesitate to contact SEI Professional Services if you want assistance interpreting AHJ requirements or to have us perform civil engineering services on your project.
