What must SESC controls minimize?

1. Erosion, sedimentation, pollution

2. Erosion, sedimentation, runoff

3. Pollution, runoff, hazards

4. Pesticides, sediments, contaminants

The correct answer is: Erosion, sedimentation, runoff

The primary goal of SESC (Soil Erosion and Sediment Control) controls is to minimize erosion, sedimentation, and runoff resulting from soil disturbance, especially during construction activities. By managing these factors, SESC measures help protect water quality and maintain the integrity of surrounding ecosystems. Erosion refers to the process where soil is worn away by natural forces, which can lead to the displacement of soil particles. Sedimentation is the accumulation of eroded soil in bodies of water, which can disrupt aquatic habitats and water quality. Runoff is the water that flows over the land surface, typically carrying sediments and pollutants into nearby waterways. The other options, while they mention important environmental concerns, do not directly relate to the explicit focus of SESC controls. For example, controlling pollution alone does not encompass the need to address soil disturbance effects, and addressing hazards is not a primary focus of SESC strategies. Ultimately, minimizing erosion, sedimentation, and runoff is crucial to achieving effective stormwater management and protecting water resources.
