Safe Drinking Water Primacy Assessment

Section 676 of Public Act 17-2 (June Spec. Sess.), signed into law in October 2017, authorizes the Department of Public Health (DPH) to collect an assessment from water companies that own Non-Transient Non-Community public water systems (NTNC) and Community public water systems (CWS). Assessment fees are established within the Public Act, based upon the classification and size of the owned system. The DPH will begin collecting the assessment, in accordance with a timeline specified in the Public Act, to support the department's ability to maintain primacy under the federal Safe Drinking Water Act (SDWA). Primacy is the responsibility to implement and enforce the SDWA. Since 1977, the DPH has been delegated primacy from the U.S. Environmental Protection Agency.  The Safe Drinking Water Primacy Summary, outlining the costs to support primacy under the SDWA, can be viewed here.  If you have questions regarding the Safe Drinking Water Primacy Assessment, please read our Frequently Asked Questions document.
