The federal Safe Drinking Water Act (SDWA) 42 U.S.C. 300f to 300j-26 has jurisdiction over the public health aspects of the drinking water supply. The Oregon Health Authority regulates public water systems in our state, including cross connection control, through Oregon Administrative Rules (OARs). One such rule is OAR 333-61-0070, which requires water districts to administer a cross connection control program that will protect the potable water supply. The City of Silverton, as required by OAR 333-61-0070, has passed an ordinance on cross connection control, Silverton Municipal Code Chapter 13.20.
