    1. SDWA 1 The Safe Drinking Water Act (SDWA)

    2. SDWA 2 Objectives Terminal Objective Given the Environmental Laws and Regulations course manual as a reference, you will be able to: Describe the general intent of the Safe Drinking Water Act (SDWA) and how drinking water regulations affect the DOE.

    3. SDWA 3 Objectives Enabling Objectives Explain why the SDWA was enacted Delineate what contaminants MCL’s and MCLG’s were established for Describe EPA’s Standard Development Process

    4. SDWA 4 Overview The Safe Drinking Water Act (SDWA) was enacted in 1974 to: Manage potential contamination threats to drinking water supplies Prevent underground injections of contaminated fluids that would endanger drinking water sources

    5. SDWA 5 Overview The SDWA standards apply to drinking water “at the tap” as delivered by public water supply systems. These standards directly affect the DOE and those facilities that meet the SDWA’s definition of a public water supply system.

    6. SDWA 6 Legislative History Section 1447 states that each Federal agency having jurisdiction over a federally owned or maintained public water system must comply with: All Federal, State, and local requirements Administrative authorities Processes and sanctions

    7. SDWA 7 Legislative History Sections 1412, 1414, and 1445(a) authorize for public water systems: Drinking water regulations Specific operating procedures

    8. SDWA 8 Legislative History 40 CFR 141.2 defines public water systems as those systems that provide piped water for human consumption and are equipped with at least 15 connections or regularly serve at least 25 people.

    9. SDWA 9 Legislative History Public water systems include the following: Community water systems Nontransient noncommunity water systems Noncommunity water systems

    10. SDWA 10 NPDWR’s The Environmental Protection Agency (EPA) was required under the SDWA to establish National Primary Drinking Water Regulations (NPDWRs) for contaminants that may cause adverse public health effects.

    11. SDWA 11 NPDWR’s NPDWRs Maximum Contaminant Levels (MCLs) and Maximum Contaminant Level Goals (MCLGs) were established for: Lead and copper Volatile organic compounds Aldicarb, aldicarb sulfoxide, aldicarb sulfone, pentachlorophenol, and barium Inorganic and organic compounds

    12. SDWA 12 NPDWR’s MCLs can be used to determine whether groundwater “contains” hazardous waste and therefore must be treated as hazardous waste.

    13. SDWA 13 DOE Applicability MCL’s and MCLGs are critical to the DOE because they can be used as applicable/ relevant and appropriate requirements under the Comprehensive Environmental Response, Compensation, and Liability Act, as amended by the Superfund Amendments and Reauthorization Act, for National Priorities List cleanups.

    14. SDWA 14 DOE Applicability Equally important to the DOE is that SDWA drinking water standards are used to determine groundwater protection regulations (i.e., the Resource Conservation and Recovery Act).

    15. SDWA 15 DOE Applicability These groundwater protection regulations apply to: DOE activities, especially storage and disposal materials containing: Radionuclides Inorganic and organic chemicals Hazardous wastes Cleanup of contaminated sites

    16. SDWA 16 Underground Injection Control The SDWA also established programs to prevent contamination of underground sources of drinking water by underground injection of contaminated fluids.

    17. SDWA 17 Underground Injection Control A final rule (53 FR 28118) responded to the Hazardous and Solid Waste Amendments Act and: protection regulations apply to: Mandated regulations on underground injection of contaminated fluids Amended existing underground injection control (UIC) regulations

    18. SDWA 18 Underground Injection Control A final rule (53 FR 28118) responded to the Hazardous and Solid Waste Amendments Act and: protection regulations apply to: (cont.) Codified the EPA’s regulatory framework for implementing the land disposal restrictions Codified the EPA’s regulatory frame-work for implementing the land disposal restrictions

    19. SDWA 19 Underground Injection Control The EPA was required to conduct the following: Publish minimum national requirements for effective State UIC programs List States that require UIC programs Make grants to States for developing and implementing UIC programs

    20. SDWA 20 Underground Injection Control The EPA was required to conduct the following (cont.): Review proposed State programs Promulgate and enforce UIC programs in listed States if the State chooses not to participate or does not develop and operate an approvable program

    21. SDWA 21 The 1986 Amendments The 1986 SDWA amendments redirected the focus of the NPDWRs by requiring the EPA to apply future NPDWRs to community and nontransient noncommunity water systems when it evaluated and revised current regulations.

    22. SDWA 22 The 1986 Amendments The 1986 amendments included the following provisions: The EPA was required to issue standards for contaminants Both regulated and unregulated chemical contaminants were to be monitored in public water systems

    23. SDWA 23 The 1986 Amendments Public notification was required for all MCL violations The EPA’s authority to enforce standards was increased by raising maximum civil penalties from $5,000 to $25,000 States were required to establish “wellhead protection areas”

    24. SDWA 24 The 1986 Amendments An immediate ban was placed on the future use of lead-containing pipes and solder in drinking water systems Filtering requirements were established The EPA was required to survey the problems of Indian reservation waters because Indian reservations were to be treated as States

    25. SDWA 25 The 1996 Amendments The 1996 amendments focused on: Prevention programs Consumer’s right to know EPA’s standards development process Federal funding

    26. SDWA 26 Prevention Programs States must submit to EPA a program delineating source water for all public water and susceptibility of that water to contamination

    27. SDWA 27 Consumer Right to Know Consumers receive an annual report with information about source water and contaminants in drinking water Consumers must be given notice within 24 hours of any violation of standards that may cause serious adverse health effects

    28. SDWA 28 Standards Development Process 1996 Amendments relaxed 1986 requirements for EPA to meet numerical quota for drinking water standards EPA must review five new contaminants every five years EPA’s decision to regulate must be based on risk based criteria

    29. SDWA 29 Standards Development Process EPA must conduct a thorough cost-benefit analysis of each proposed new standard, and adjust MCLs to a level that “maximizes health risk reduction benefits at a cost that is justified by the benefits”

    30. SDWA 30 SDWA Enforcement States have primary SDWA enforcement authority, although the EPA will step in if the law is not properly enforced. The Federal Government provides funds to assist the States with enforcement of the Act.

    31. SDWA 31 Review Question The Safe Drinking Water Act amendments of 1996 require specific actions to notify consumers about the quality of water from their public water system. a. True b. False
