Prep for T4 and T5 Operators: Regulations/Administrative Duties  \nBy Dan Gill, T5, MPA Water Treatment Superintendent EBMUD  \nSafe Drinking Water Act  \n• In 1974, the Safe Drinking Water Act (SDWA) was signed into law, giving the federal government, through the EPA, the authority to:  \n– Set National standards regulating the levels of contaminants in drinking water  \n– Require public water systems to monitor and report their levels of identified contaminants  \n– Establish uniform guidelines specifying the acceptable treatment technologies for cleaning drinking water of unsafe levels of pollutants  \n• The EPA sets two types of standards, primary regulations establish maximum contaminant levels (MCLS) based on the health significance of the contaminants  \n• The secondary standards are established on aesthetic considerations and are a state option  \n• The SDWA gave EPA responsibility for developing drinking water regulations, it gave state regulatory agencies the opportunity to assume primary responsibility for enforcing those regulations .  \nPrimacy  \n• In California, the Division of Drinking Water (DDW) regulates localities  \n• It is essential for utilities to partner with their local DDW representatives and stationary engineers  \n• Stay up to date on upcoming regulations, approve and access treatment facilities  \n• SDWA amended in 1986 and 1996  \n– With emphasis on enforcement, authorizing penalties for tampering with drinking water supplies, mandated the complete elimination of lead from drinking water  \nPublic Water System  \n• Defined as any public or private system that:  \n– Has 15 service connections, or  \n– Regularly serves an average of at least 25 individuals daily at least 60 days out of the year  \n• Community or non-community systems are defined as:  \n– Has at least 15 service connections used by all-year residents  \n– Regularly serves at least 25 all-year residents  \n• Any public water system that is not a community water system is classified as a noncommunity water system . Restaurants, campgrounds, and hotels could be considered noncommunity systems for purposes of drinking water regulations  \n• Nontransient noncommunity systems  \n– Regularly serve at least 25 of the same persons over 6 months per year  \n• This classification applies to water systems for facilities such as schools or factories where the consumers served are nearly the same every day but do not actually live at the facility  \nSurface Water Treatment Rule  \nEvolution  \n• Original SWTR – 1989  \n• IESWTR  \n• LT1ESWTR  \n• LT2ESWTR  \n– CA State adoption of LT1ESWTR and LT2ESWTR was included in the CA Cod of Regulation (CCR) on July 1, 2013 . The adoption is included in Title 22, Chapter 17 (Surface Water Treatment), CCR  \nSurface Water Treatment Rule  \n• Applies to all public water systems using approved surface water;  \n• Establishes treatment techniques for:  \n– Turbidity, Giardia, viruses, Cryptosporidium, Legionella, and Heterotrophic plate count bacteria  \n• Requires multi-barrier treatment;  \n– Series of water treatment processes that provide for both removal and inactivation of waterborne pathogens  \n• Requires systems to disinfect  \n• Requires individual and combined filter effluent monitoring and limits  \n• Title 22 Chapter 17, CCR","cbCaipJSIk8kIQE1","https://ap.wps.com/l/cbCaipJSIk8kIQE1","pdf",5876206,97,"English","# Exam Prep for T4 and T5 Operators\n## Regulations and Administrative Duties\n## Safe Drinking Water Act (SDWA)\n## Primacy\n## Public Water System Definitions\n## Surface Water Treatment Rule (SWTR)\n## Surface Water Treatment Rule Requirements\n## CA Regulations: Title 22 Chapter 17, CCR","[{\"question\":\"What authority does the Safe Drinking Water Act give the federal government through the EPA?\",\"answer\":\"It authorizes the EPA to set national contaminant standards, require public water systems to monitor and report contaminant levels, and establish guidelines for acceptable treatment technologies.\"},{\"question\":\"How does California handle enforcement authority under SDWA (primacy)?\",\"answer\":\"In California, the Division of Drinking Water regulates localities, and utilities are advised to partner with DDW representatives and stationary engineers while staying current on upcoming regulations.\"},{\"question\":\"What does the Surface Water Treatment Rule require for public water systems using approved surface water?\",\"answer\":\"It requires multi-barrier treatment, disinfection, and filter effluent monitoring with limits, covering treatment techniques for turbidity and pathogens such as Giardia, viruses, Cryptosporidium, Legionella, and heterotrophic plate count bacteria.\"}]","Exam Prep for T4 and T5 Operators - Regulations/Administrative Duties | PDF",1790517571,244]
