REGULATION. TECHNOLOGY. POLICY. WE HAVE AN EYE ON THE FUTURE. 18 SOURCE spring 2013 USEPA is in the midst of developing a handful of new national regulations for inorganics. Some inorganics are under consideration for a new standard while others would be addressed by revising an existing standard. For a new contaminant, the 1996 Safe Drinking Water Act (SDWA) Amendments require EPA to use a four-step process for developing a national drinking water regulation: • On a five-year cycle, EPA publishes a Contaminant Candidate List (CCL) for contaminants that could be considered for a national regulation. • Also on a five-year cycle, EPA is required to make decisions, known as regulatory determinations, on at least five contaminants. Besides a binary yes/no on regulating or not regulating a specific contaminant, EPA can make other decisions such as issuing guidance or a health advisory, or that more research is needed for a specific contaminant. • If EPA decides to regulate a specific contaminant, then it has 24 months to publish the propose regulation. • The final regulation has to be published 36 months after the above decision. EPA is also required by SDWA to review all existing regulations every six years to take into account any new health effects or occurrence data, new analytical methods and any new treatment research. The sixyear review is the process through which an existing standard is revised. 2013 Regulatory Actions This year EPA will propose three regulatory actions for inorganics, with the first being the “preliminary third regulatory determination” in the summer. Based on the information presented at a stakeholder meeting in Washington, DC in June 2011, positive determinations are likely for nitrosamines, chlorate and strontium, The Regulatory Horizon Inorganic Contaminants— By J. Alan Roberson, P.E., AWWA Director of Federal Regulations CA-NV AWWA hosted a twoday symposium on inorganic contaminants in Sacramento on February 5-6, 2013.The following article is based on Alan Roberson’s opening keynote from the symposium and takes a look at what AWWA sees on the regulatory horizon.
