Section 5: BMP Types and Selection

BMPs for control of urban runoff can be generally grouped into two major categories that include; 1) source control BMPs and 2) treatment control BMPs. Source control BMPs are practices that prevent pollution by reducing potential pollutants at their sources before they come into contact with stormwater, while treatment controls, as the name implies, are methods to treat or remove pollutants from stormwater (ASCE, 1998). Table 5-1 provides a listing of source control BMPs, and Table 5-2 provides a listing of treatment control BMPs and whether or not guidelines are provided in this series of documents.
