EPA Issues National Requirements to Protect U.S. Waterways
On September 24, the U.S. Environmental Protection Agency (EPA) finalized national discharge standards aimed at regulating pollutants released by approximately 85,000 vessels operating in U.S. waters. The Vessel Incidental Discharge National Standards of Performance will address discharges from large vessels, focusing on harmful pollutants such as bacteria, pathogens, oil, and grease, while also curbing the spread of invasive species that threaten ecosystems and infrastructure. This rule is part of an effort to create consistent nationwide requirements, replacing the previous patchwork of federal, state, and local regulations.
The new standards primarily target non-recreational vessels 79 feet or longer, including commercial and research ships. They require the implementation of best management practices for 20 different types of discharges, ensuring that vessels operate with more environmentally friendly systems. For instance, future “Lakers” operating in the Great Lakes must utilize ballast water management systems to mitigate invasive species risks. While the new regulations will not be enforced for up to two years as the U.S. Coast Guard develops corresponding rules, they underscore the importance of maintaining clean waterways that support local economies, drinking water sources, and natural ecosystems—critical considerations for professionals in homebuilding and development.
