Which Utah wastewater plant received the largest EPA penalty?

Cedar City Regional Wastewater Treatment Facility in Cedar City: $6,450 assessed in fiscal year 2011 (Cedar City Regional Wastewater Treatment Plant, 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 Utah is from Feb 2017.
