Environmental Groups Argue in Court Against Maryland’s Industrial Stormwater Permit
Apr 28, 2026
On April 28, 2026, Chesapeake Legal Alliance (CLA), alongside partner organizations, argued in the Circuit Court for Baltimore County that Maryland’s industrial stormwater permit fails to meet the requirements of state and federal clean water laws. CLA represents Blue Water Baltimore and Gunpowder Riverkeeper in the case, which challenges the Maryland Department of the Environment’s (MDE) “20-SW” general permit regulating stormwater discharges from more than 1,000 industrial facilities across the state. Environmental groups argue that the permit fails to address climate change, allows toxic pollutants to reach waterways, and does not adequately protect communities most at risk.
