| Reporting term | Individual BMPs (BMP Properties --> BMP Summary) | Model-Wide Summary ("Results" Tab) | |
|---|---|---|---|
| Pollutant Loading: TSS, TPP, and TDP1 | |||
| Inflow Loading (lbs) | "Annual [Pollutant] from direct watershed" & "upstream BMPs" | "Post development annual [Pollutant] load"; (A) | |
| Pollutant Removal (lbs) | "[Pollutant] load reduction" | "Annual [Pollutant] removed by BMPs"; (B) | |
| Outflow Loading* (lbs) | "[Pollutant] load outflow" | (A) - (B) | |
| Outflow Loading (ppm; mg/L) | "Annual Outflow Volume" | ["Post dev. annual runoff volume"] - ["Annual runoff volume removed by BMPs"] | |
| Outflow* (acre-feet) | [Outflow Loading*] / [Outflow*] x [CF2] | ||
| Watershed and Areal Loading Calculations | |||
| Contributing Watershed Area* (acres) | See "Watershed" tab of BMP and all upstream BMPs | See "Total Site Area" summary | |
| Watershed pollutant areal loading (pre-treatment) (lbs/acre/year) | [Watershed Loading*] / [Contributing Watershed Area*] | ||
| Outflow pollutant areal loading (post-treatment) (lbs/acre/year) | [Outflow Loading*] / [Contributing Watershed Area*] | ||
TSS=total suspended solids; TPP=total particulate phosphorus; TDP=total dissolved phosphorus
2CF = Conversion factor to convert to ppm; mg/L units = 0.367733624
