From Summary: "This report describes and analyzes H.R. 4024 and S. 1961, as reported. The bill share a number of broadly similar provisions-both would direct states or the Environmental Protection Agency (EPA) to establish programs to prevent and respond to releases from chemical storage facilities (H.R. 4024) or tanks (S. 1961) located near drinking water sources-but they take different approaches to doing so; S. 1961 would make programmatic changes by amending the Safe Drinking Water Act (SDWA), while H.R. 4024 would amend the Clean Water Act (CWA)."
