The Wisconsin Department of Natural Resources (DNR) will host a virtual public informational hearing to share information and take public comments on a proposed modification to the Wisconsin Pollutant Discharge Elimination System permit for the We Energies Elm Road Generating Station in Oak Creek to authorize use of a new wastewater treatment system.
The meeting will take place online via Zoom at 5 p.m. Monday, Nov. 20.
To comply with recent federal regulations, the We Energies Elm Road Generating Station has installed advanced treatment for wastewater from the plant’s flue gas desulfurization system, which is an air scrubber used to remove sulfur dioxide from air emissions. Once operating, this system will provide enhanced removal of contaminants including mercury, arsenic, selenium and nitrate/nitrite before discharge to Lake Michigan.
To monitor compliance with the new federal regulations, on Sept. 12, the DNR proposed to modify the facility’s existing Wisconsin Pollutant Discharge Elimination System permit to establish a dedicated sampling point for treated flue gas desulfurization wastewater. This proposed permit action does not increase existing limitations for mercury, arsenic or any other pollutants at the final outfall.
The hearing will include an informational presentation and the opportunity to provide comments or ask clarifying questions of DNR staff related to the proposed permit modification.
More information on the proposed modification and hearing is available on the DNR's website at https://dnr.wisconsin.gov/topic/Wastewater/PublicNotices.html.
