The significant increase in recent years of nitrogen and phosphorus (nutrient pollution) in water bodies across the country has intensified water quality problems. Excess nitrogen and phosphorus in Utah waters harm our streams, rivers, and lakes. The Division of Water Quality (DWQ) is currently at work on a nutrient reduction plan tailored to the unique…

The Division of Water Quality’s (DWQ) Nutrients in Utah’s Water study (2010) evaluated the ecological impacts of nutrient additions from POTWs on the State’s streams and rivers. The study was conducted on receiving waters above and below the discharges of eight mechanical treatment plants and one lagoon system. The Division studied these waters above and…

The Utah Division of Water Quality (DWQ) is funding a study to quantify the economic benefits and costs of implementing nutrient criteria for surface waters in Utah. Human-caused nutrient inputs of nitrogen and phosphorus to the nation’s waters have been identified as significant threats to aquatic life and recreational uses. In response, the US Environmental…

The Utah Division of Water Quality conducted the 2009 Statewide Nutrient Removal Cost Impact Study to evaluate the economic impacts of potential new nutrient removal requirements for Utah’s publicly owned treatment works (POTWs). The study estimated economic, financial, and environmental impacts associated with a range of potential nutrient discharge standards for every discharging POTW in…

On June 26, 2019, Utah’s Water Quality Board passed numeric nutrient criteria to protect aquatic life and recreation uses in headwater streams effective date: July 1, 2019. This page contains background information on this important water quality standard revision. Documentation includes a classification report (4 MB) that demonstrates that statewide nutrient-response relationships are likely to…

Technology-Based Phosphorus Effluent Limits The Utah Water Quality Board adopted a new rule for control of phosphorus discharges into waters of the state that will become effective January 1, 2015. The Technology-Based Phosphorus Effluent Limits or TBPEL Rule, R317-1-3.3 requires that discharges having reasonable potential to discharge phosphorus implement new water quality monitoring requirements by…
