DC requires Erosion and Sediment Control (ESC) plans for all land-disturbing activity exceeding 50 square feet, one of the strictest thresholds in the US. DOEE administers the program under 21 DCMR Chapter 5 Section 540 and the Soil Erosion and Sedimentation Control Act of 1977. Silt fencing, stabilized construction entrances, and inlet protection are standard. A Responsible Person must be designated for every site.
DC's erosion and sediment control regime is governed by the Soil Erosion and Sedimentation Control Act of 1977 (DC Code section 8-651) and 21 DCMR Chapter 5 Section 540 et seq., administered by DOEE's Soil Erosion and Sediment Control (SESC) program. DC uses one of the lowest thresholds in the nation: any land-disturbing activity affecting more than 50 square feet requires an approved Erosion and Sediment Control Plan. Plans must be submitted to DOEE as part of the Department of Buildings permit process, with ESC as an integral component of the Stormwater Management Plan for larger sites. Required BMPs include: stabilized construction entrances (to keep mud off city streets), perimeter silt fencing, inlet protection on catch basins within 200 feet, dust control (critical on Anacostia-bordering sites), temporary seeding within 14 days of inactivity, and permanent stabilization within 7 days of finished grade. Each site must designate a Responsible Personnel, who must have completed DOEE Soil Erosion Control training. Inspections occur at pre-construction, during active work, and final. Failures trigger Notices of Violation, stop-work orders, and fines that escalate quickly if sediment reaches storm drains or waterways. Hazardous construction sites near the Potomac or Anacostia receive heightened oversight due to the federal MS4 permit and the Clean Water Act. DC's high rainfall, clay soils, and aging combined sewer system make erosion control particularly consequential.
No ESC plan on required site: stop-work order, $500-$2,500 per DCMR 21-540. Sediment escape to street or drain: $1,000-$10,000 per day under Clean Water Act provisions of DC Code 8-651. Failure to stabilize within 7/14 days: notice plus $500 daily. Unauthorized clearing: up to $25,000.
