QAQC / Review item | Related MIDS Calculator Output |
---|---|
Confirm total watershed area is correct | Review land use-based area assigned in the "total load" table |
Confirm annual precipitation totals are correct | Review annual rainfall values in column G and confirm all are the same value |
Review watershed pollutant concentrations | Compare watershed areal loading values in the "total load" table to literature values in Table 9 |
Review watershed routing to BMPs | Review land use-based area assigned to each BMP type |
Confirm only the directly-contributing watershed area is applied for each BMP | As noted in Section 4.2.2, the area assigned to a given BMP should be only the directly-contributing watershed area and should NOT include area tributary to other BMPs upstream |
Review TSS/TP removal rates | Compare pollutant removal values to literature values in Table 21. Note: percent load reduction shown for each BMP type is calculated based on the total watershed loading |
Review BMP sizing recommendations and review contributing watershed area | As described in Section 4.2.2, bypass from undersized BMPs is not calculated. For this reason, only the area for which the BMP is correctly-sized should be modeled to the BMP (the remainder should be modeled as untreated). |
