Delaware Erosion and Sediment Control Statewide Standards

7 Del.C. Chapter 40 declares it state policy to prevent soil erosion and sedimentation pollution of state waters. The statute authorizes DNREC, in coordination with the three Conservation Districts (New Castle, Kent, Sussex), to require erosion and sediment control plans for land-disturbing activities. Plans must conform to the Delaware Erosion and Sediment Control Handbook (effective July 2023), which prescribes silt fencing, stabilized construction entrances, sediment basins, slope stabilization timing, and inspection frequencies. Certified Construction Reviewers and contractors must complete state training. Conservation Districts review and approve most plans on DNREC's behalf.

Operating without an approved plan, failing to install or maintain controls, or refusing inspector access can result in stop-work orders, civil penalties up to $10,000 per day, and mandatory site restoration under 7 Del.C. § 4014.
