EPA Finalizes National Discharge Standards For Vessels To Protect U.S. Waters

43

The U.S. Environmental Protection Agency (EPA) has finalized national discharge standards aimed at controlling pollutants and invasive species from approximately 85,000 vessels operating in U.S. waters. These standards, part of the EPA’s Vessel Incidental Discharge National Standards of Performance final rule, target discharges that occur during normal vessel operations, addressing harmful pollutants and invasive species that threaten ecosystems stated by EPA.

Key Focus Areas of the Rule

The new standards will control pollutants such as bacteria, oil, grease, metals, and pathogens, and help reduce the spread of invasive species, like zebra mussels. This rule applies to commercial, research, and emergency rescue vessels, as well as ballast water from smaller fishing vessels, ensuring the protection of aquatic ecosystems and drinking water sources.

Best Practices and Treatment Standards

The EPA’s final rule includes best management practices and treatment standards for 20 different types of discharges. For instance, “Lakers” – large vessels in the Great Lakes – will be required to have ballast water management systems, significantly helping to mitigate the spread of invasive species across the region.

Transition Period and Implementation

The new standards will take up to two years to implement as the U.S. Coast Guard develops corresponding regulations. In the meantime, vessels must comply with the EPA’s 2013 Vessel General Permit and the U.S. Coast Guard’s existing ballast water regulations, along with any state or local requirements.
