Which agency requires operators of construction sites to establish sedimentation and erosion control plans for sites of one acre or larger?

• A. OSHA
• B. DOT
• C. FCC
• D. Environmental Protection Agency

Answer: (D)

The main idea here is understanding which agency governs environmental controls on construction sites disturbing a certain size of land. For sites of one acre or larger, the Environmental Protection Agency requires operators to establish sedimentation and erosion control plans to prevent sediment from leaving the site and polluting waterways. This falls under the Clean Water Act permit program for construction activities, often implemented as a stormwater and sediment control plan (SWPPP/SECP). The plan outlines practices to stabilize soils, manage runoff, and use features like silt fences, sediment basins, and stabilized entrances to keep sediment on-site and protect water quality. The other agencies listed focus on different areas—OSHA on worker safety, DOT on transportation infrastructure, and FCC on communications—so they don’t govern this specific environmental permit requirement.
