This document provides a history of stormwater regulation in the United States from the 1970s to present. It establishes the U.S. Environmental Protection Agency (EPA) in 1970 to regulate water pollution and passage of the Clean Water Act in 1972 granting the EPA authority to regulate water discharges. The Water Quality Act of 1987 provided the basis for how stormwater is currently regulated and in 1990 the EPA began regulating stormwater at industrial facilities nationwide. The document also discusses state regulatory authorities in Texas, requirements for Stormwater Pollution Prevention Plans and Spill Prevention Control and Countermeasure Plans, and risks of non-compliance with environmental regulations.
