Potawatomi's $20 million waste-to-energy plant violated wastewater permit with excessive discharges

The Potawatomi's $20 million facility in the Menomonee Valley to convert food waste to biogas fuel — heralded as cutting-edge renewable energy technology when it opened in 2013 — repeatedly has flushed too much of fats, oil and grease to sewers in violation of its wastewater permit, records show.

The Milwaukee Metropolitan Sewerage District has notified the waste-to-energy plant of a series of permit violations since April 2017, MMSD water quality protection manager Sharon Mertens said.
