The CWA and a direct application of the Court’s Maui decision provide important protections for the nation’s waters. This action ensures appropriate regulation of discharges of pollutants to groundwater that also reach surface waters. This action will help protect water quality in lakes, streams, wetlands, and other waterbodies. EPA will work with state permitting agencies and the regulated community to implement the Court’s decision Maui, consistent with law and science.
The Office of Water is evaluating appropriate next steps. EPA will continue to apply site-specific, science-based evaluations to determine whether a discharge from a point source through groundwater that reaches surface water requires a permit under the CWA. The agency is committed to working with its state co-regulators, Tribes, and local partners to better protect water quality that is essential to public health and thriving ecosystems.____________________ Source
