Georgia EPD approves higher wastewater discharge limits for Hyundai Metaplant, denies requests for stricter permit terms
The state's decision raises how much wastewater the Hyundai Metaplant's pretreatment facility can discharge, while rejecting calls to deny the permit or add PFAS and extra monitoring requirements.
No next step has been documented.

What this means now
The story
Georgia's Environmental Protection Division proposed modifying Pretreatment Permit GAP050365, covering wastewater discharge from Hyundai Motor Group Metaplant America LLC's facility, with a maximum flow of 0.865 million gallons per day and an average of 0.676 million gallons per day, along with limits for pollutants including BOD5, TSS, COD, pH, phosphorus and cyanide.
The draft modification also removed stormwater as a listed contributing wastestream based on the facility's updated application, changed how sludge from the treatment process is disposed of — now landfilled through Waste Management rather than applied to land — and removed references to the City of Savannah's Travis Field water reclamation facility, which no longer receives wastewater from the North Bryan facility.
EPD denied a public comment asking the agency to deny the permit modification altogether, denied a request to add PFAS monitoring parameters to the permit, and denied Ogeechee Riverkeeper's request for an operational-based increase in how often monitoring occurs, saying the existing monitoring frequency is sufficient to assess compliance.
EPD approved the permit modification, increasing the facility's wastewater discharge limits, effective October 1, 2026.
