Norfolk County does not enforce erosion control. Each municipality requires erosion and sediment controls on construction sites under local bylaws, the Wetlands Protection Act, and EPA construction general permit.
Erosion and sediment control in Norfolk County operates at multiple levels. Local: each town's building/engineering code requires an erosion control plan for grading permits; Brookline, Dedham, Weymouth have detailed stormwater bylaws covering construction. State: MA Wetlands Protection Act (MGL c. 131 §40) requires Conservation Commission review for work within 100 ft of wetlands. Federal: EPA Construction General Permit required for disturbance of 1+ acre. Standard BMPs include silt fencing, straw wattles, erosion control blankets, stabilized construction entrances, and sediment basins. Disturbed areas must be temporarily stabilized within 14 days of activity cessation per EPA CGP. Permanent stabilization required at completion. Conservation Commission site inspections are common.
No county enforcement. Municipal missing controls: stop-work order, $250-$2,500. Sediment discharge to wetlands under MGL c. 131 §40: $25,000/day. Federal CGP violations: up to $56,460/day.
