What is a stormwater pollution prevention plan (SWPPP)?

A stormwater pollution prevention plan (SWPPP) is specifically designed to minimize the discharge of pollutants from construction sites into nearby waterways. The plan outlines best management practices and control measures that should be implemented to reduce the potential for contaminants such as sediments, oils, and chemicals from being washed into storm drains and ultimately, local streams or rivers.

The SWPPP typically includes site-specific information, including a description of the project, an assessment of the potential sources of pollution, and a detailed description of the strategies that will be employed to prevent stormwater pollution. This is particularly critical during construction activities, as these sites often expose soil and materials that can easily be washed away during rainfall, leading to increased sedimentation and pollution in water bodies.

In contrast, other options focus on different areas. Safe transportation of hazardous materials relates to the handling and movement of potentially dangerous substances, rather than addressing stormwater concerns. Similarly, a forecast of potential water supply issues would deal with water availability or demand, and not directly with managing stormwater during construction. Lastly, a compliance strategy for wastewater treatment is concentrated on the treatment of wastewater rather than the prevention of stormwater pollution. Thus, the choice that accurately describes the role of a SWPPP is centered on preventing pollution from construction
