The Wisconsin DNR is currently seeking comments on the proposed wastewater discharge permit (WPDES permit) for the We Energies Valley Power Plant, which discharges 122 million gallons of heated cooling water per day into the South Menomonee Canal of the Menomonee River. In addition, this plant withdraws up to 160 million gallons of water per day to cool the plant, killing an estimated million fish per year (not including eggs and larvae) in the process.
Valley’s WPDES permit is one of the oldest expired water permits in the country, last being issued in 1987, and expiring in 1992. For the last 20 years, Valley has been operating on their old permit requiring antiquated technology that is not in compliance with new laws, regulations, or science. Given the extremely long wait for this permit, we are surprised by its failure to incorporate new thermal and phosphorus regulations.
