Which Missouri wastewater plant received the largest EPA penalty?

Metropolitan St Louis Sewer District-Grand Glaize Wastewater Treatment Plant in Valley Park: $1.2 million assessed in fiscal year 2003 (METROPOLITAN ST LOUIS SEWER DISTRICT; MSD, Final Order With Penalty). Penalties are the amounts EPA records as assessed or agreed, not necessarily what was collected.

What does an EPA administrative order mean for a wastewater plant?

Most cases here are administrative orders under section 309 of the Clean Water Act: EPA finds permit violations, usually effluent limits or discharge without a permit, and orders the plant to return to compliance, often with a corrective action plan, a schedule and sometimes a penalty. Judicial cases go through the Department of Justice and typically end in a consent decree with a capital programme behind it. The latest case in Missouri is from Jul 2026.
