How do NPDES Permits Regulate Stormwater?

(upbeat electronic music) [JUSTIN MANSBERGER] Did you know that stormwater is the number one source of pollutants entering our waterways? Well, it's true. That's why stormwater management is so important. Let's find out how stormwater can impact our environment and how government agencies are working to protect our water. Why does stormwater matter? When it rains, water flows over streets, parking lots, and construction sites, picking up pollutants along the way. Stormwater can lead to serious problems like erosion, flooding, and even health risks for people and animals. To manage these issues, the US Environmental Protection Agency and the Pennsylvania Department of Environmental Protection, or DEP, regulate and monitor stormwater. They regulate stormwater through a permit system called the National Pollutant Discharge Elimination System, or NPDES. Npdes permits are required for many communities with Municipal Separate Storm Sewer systems, or MS4s, construction sites, industrial facilities, and even transportation systems like highways. These permits set clear limits on pollutants and require a written action plan to keep stormwater contaminants under these limits. A stormwater management program is required for cities, municipalities, and certain businesses. The program plan outlines steps to control stormwater discharges to protect local waterways. Industrial and construction sites have strict rules. They must use controls like sediment socks and drainage systems to prevent soil and chemicals from washing away during rainstorms. All transportation activities are monitored too. The Pennsylvania Department of Transportation and the PA Turnpike Commission must follow stormwater management plans. Stormwater is often carried and discharged untreated into local waterways, so management plans specify practices to minimize these discharges. NPDES permit holders are required to monitor their stormwater management activities and report any problems. If they violate their permit, they can face fines, legal action, and even jail time for serious non-compliance. Stormwater might seem like it's just rain, but when it carries pollution, it becomes a threat to our environment and health. The NPDES program helps protect water by making sure local government, industry, construction sites, and highway systems handle stormwater responsibly. When it comes to keeping our water clean, every drop matters. (upbeat electronic music)
