We invite you to comment on the draft industrial wastewater permit for Lakeside Foods in Brooten.
Lakeside Foods in Brooten is located at 500 Industrial Park Rd in Brooten. This facility processes peas, green beans, sweet corn, legumes, root crops, and other vegetables.
The wastewater treatment system consists of screening, tank storage, and three spray irrigation sites totaling 261 acres. A 10-million-gallon wastewater pond is available for storage when conditionals are not suitable for direct spray irrigation. The wastewater consists of process wastewater, cleanup water, non-contact cooling water, silage leachate, and stormwater. The maximum volume discharged to the spray irrigation system is 77.95 million gallons per year. Spray irrigation sites are not tile drained and are established with a grass cover crop. Groundwater is monitored with a network of seven monitoring wells (GW 001 to GW 007) located around the wetted perimeter of the spray sites.
Sanitary wastewater is discharged to the city of Brooten’s wastewater treatment facility. Industrial stormwater discharge is permitted to discharge to SD 001 stormwater outfall.
The draft wastewater permit includes changes such as adding one stormwater sampling location, new pond monitoring requirements, and decreased spray irrigation sites. Additional parameters were added to the wastewater monitoring for spray irrigation: total calcium, total magnesium, total dissolved solids, and sodium adsorption ratio (SAR) monitoring. The frequency of monitoring also increased from monthly to weekly for this waste stream. Well monitoring was changed to include total dissolved solids monitoring and added chloride intervention limits to downgradient wells.
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.
