Stormwater runoff is a significant source of pollution to the nation’s waters. Stormwater Pollution Prevention has become a requirement for almost all civil projects during the design and construction phases. Control of pollutants in stormwater runoff from construction activities is a major environmental concern. Phase II regulations have increased awareness of surface water and stormwater quality. The U.S. EPA and NPDES permit regulations require a stormwater management plan be developed and implemented at almost all construction sites. GSE has Certified Erosion and Sediment Control Professionals on staff to help you comply.
