Alexandria Extrusion - Wastewater Permit
We invite you to comment on the draft wastewater permit for the Alexandria Extrusion Company.
Alexandria Extrusion Company manufactures extruded aluminum parts. Wastewater from its facility is created from core extrusion, press heat treatment with contact cooling water, cleaning and tumbling of extruded parts, and machining of extruded parts as well as discharge from cooling water and the reject from the reverse osmosis water treatment unit. All treated wastewater from the facility discharges via the sanitary sewer to the wastewater treatment facility operated by the Alexandria Lakes Area Sanitary District.
The draft water quality permit is subject to federal regulations for aluminum forming facilities, which include production-based standards that are calculated using the past five years of production information. The permit limits total chromium, total cyanide, total toxic organics, total zinc, and pH.
Wastewater from industrial and commercial sources may contain pollutants at levels that could adversely affect the water quality in area wetlands, streams, rivers, and lakes. Water quality permits - or National Pollutant Discharge Elimination System (NPDES) permits - establish specific limits and requirements to protect Minnesota's surface and groundwater quality. All wastewater must be treated before it goes into surface water to protect human health and aquatic life. Permits are regularly reviewed and updated as they expire, allowing the MPCA to incorporate new information about the impacts of pollutants on the environment in future permits.
