ensuring that all new and existing water systems have the technical, managerial and financial capacity to comply with NPDWRs. Systems that do not commit the resources required to comply with the new rules may not be eligible for Drinking Water State Revolving Fund (DWSRF) loans, and may be vulnerable to enforcement actions. The major components of the SDWA of interest to the City of Ramsey are as follows: • National Primary Drinking Water Regulations (NPDWRs) • Radionuclides Rule (except radon) • Radon Rule • Disinfection/Disinfection By -Products Rules (D/DBP) • Total Coliform Rule • Groundwater Rules • Drinking Water Contaminant Candidate List (DWCCL) The following paragraphs summarize each of these components. 2. National Primary Drinking Water Regulations (NPDWRs) NPDWRs are the enforceable standards with which water suppliers must comply. Currently, there are standards for 92 contaminants, including turbidity, 8 microorganism indicators, 4 radionuclides, 19 inorganic contaminants, and 60 organic contaminants. The United States Environmental Protection Agency (EPA) is required to review and revise, as appropriate, each NPDWR every six years. 3. Radionuclides Rule (except Radon) The final radionnuclides rule was promulgated by the USEPA on December 7, 2000. The rule updates the maximum contaminant level (MCL) for radium 226/228, alpha emitters, gross beta and photon emitters and sets a new standard for uranium. The compliance date, which applies to all community water systems, is December 8, 2003. Maximum limits have been established to limit the health effects of naturally occurring radionnuclides (a measure of radioactivity) and other potential radiation exposures for vulnerable systems near nuclear City of Ramsey, Minnesota — M21.34343 Page 4-2 Water System Study Prepared by Bolton & Menk, Inc.
