Phosphorus Pollutant Category

All phosphorus and phosphate pollutant parameters. Section 3.1.3 of the Technical Users Background Document for the DMR Pollutant Loading Tool describes how the Loading Tool identifies phosphorus parameters and aggregates phosphorus loads.

Search Considerations: The Loading Tool selects pollutant loadings for the Phosphorus category if the loadings are associated with parameter codes in ICIS-NPDES and PCS that are on the phosphorus list. This list is available in the Technical Users Background Document for the DMR Pollutant Loading Tool.
