The CGP applies to which type of pollution discharges?

• A. Air emissions.
• B. Wastewater discharges.
• C. Noise pollution.
• D. Stormwater discharges.

Answer: (D)

Stormwater discharges from construction activities are what the Construction General Permit covers. This permit is part of the NPDES program and is designed to prevent polluted runoff from construction sites—like sediment, dirt, and chemicals carried by rainwater—from reaching nearby streams, rivers, and lakes. To comply, sites must develop and implement a Storm Water Pollution Prevention Plan (SWPPP) with erosion and sediment control BMPs, stabilization measures, and procedures for inspections and maintenance. The rule applies to sites disturbing one acre or more (or smaller sites that are part of a larger development plan). It does not address air emissions, wastewater discharges, or noise pollution, which are governed by other programs.
