Storm Water Discharge

Storm water is defined as storm water runoff, surface runoff, and drainage. The regulations apply only to point-source discharges. A permit is required for both direct discharges into U.S. waters and for indirect discharges into a facility's drainage system or a separate city storm water system. However, an industry that separates its nonindus-trial storm water, such as drainage from office buildings and parking lots, from the plant's industrial storm water does not have to include the nonindustrial areas in their permit.

These industrial discharges must meet effluent standards under sections 301 and 402 of the CWA, including the use of BAT and best practicable control technology (PCT). Industrial discharges must apply best management practices (BMPs) to control and reduce storm water discharges. These standards are technological and are measures and controls designed to eliminate or minimize pollutant loadings in storm water discharges.

General BMPs include good housekeeping, preventative maintenance, visual inspection, spill prevention and response, sediment erosion prevention, management of runoff, employee training, and record keeping and re-
