Which of the following correctly describes structural controls?

Structural controls are defined as physical features designed to manage and mitigate storm water pollution. They include various engineered solutions such as retention basins, filter strips, berms, and green roofs, which physically alter the flow and quality of storm water runoff to prevent pollution from entering water bodies.

The primary function of structural controls is to contain, segregate, or treat storm water before it discharges into the environment. By implementing these physical structures, industries can reduce the volume of runoff, improve water quality, and comply with environmental regulations.

In contrast, promotional efforts, training programs, and regulatory guidelines, while important components of storm water management, do not directly act on storm water in a physical manner. They instead focus on education, compliance, and procedural directions, reinforcing that structural controls are distinctly about the physical modifications made to the landscape or facilities to manage storm water effectively.
