This Request for Applications (RFA) is issued pursuant to Clean Water Act (CWA) §319(h), which authorizes the EPA to award grants to eligible Tribes and intertribal consortia to implement approved Nonpoint Source (NPS) management programs developed pursuant to CWA §319(b)(1) “for controlling
pollution added from nonpoint sources to the navigable waters” and “improving the quality of such waters.” NPS management programs must identify “best management practices and measures which will be undertaken to reduce pollutant loadings resulting from each category, subcategory, or particular nonpoint source” identified in the Tribe’s NPS assessment report developed pursuant to CWA §319(a).
