EPA enforcement in Pennsylvania: questions

  1. How many EPA enforcement actions have been taken against wastewater plants in Pennsylvania?

    EPA's enforcement records list 99 formal civil enforcement cases naming publicly owned wastewater treatment plants in Pennsylvania, 16 of them since fiscal year 2020. They involve 61 of the state's 788 plants. Informal actions such as notices of violation are not counted here.

  2. Which Pennsylvania wastewater plant received the largest EPA penalty?

    Allegheny Cnty Sani Auth/allegheny Cnty in Pittsburgh: $1.2 million assessed in fiscal year 2000 (ALLEGHENY COUNTY SANITARY AUTHORITY (ALCOSAN), Final Order Entered). Penalties are the amounts EPA records as assessed or agreed, not necessarily what was collected.

  3. 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 Pennsylvania is from Sep 2026.

Enforcement data: EPA ICIS-FE&C civil enforcement cases and ICIS compliance inspections, via ECHO. Penalties are the amounts assessed or agreed in each case as EPA records them. Latest case status in this data: Sep 2026.
