Nutrient Related Permitting in TN

All municipal wastewater facilities in Tennessee operate under NPDES or State Operating permits. These permits impose water quality-based limits for Ammonia, Total Nitrogen, and Total Phosphorus to prevent further degradation of receiving water bodies.

Tennessee Nutrient Optimization Program (TNPOP)

Tennessee Nutrient Optimization Program (TNPOP) offers incentives to voluntarily optimize biological nutrient removal in municipal wastewater operations. By 2030, TNPOP aims to reach all municipal mechanical plants, assisting with process optimization, necessary upgrades, and funding incentives.
