 AWWA recommendations
 Next steps in the hypochlorite registration review process
 Discuss path forward to minimize perchlorate and chlorate  -  potential label changes for registration review

EPA is reviewing the sodium and calcium hypochlorite chemicals in the registration review program. EPA Antimicrobials Division staff and industry representatives met to discuss factors impacting formation of two potential hypochlorite degradates - chlorate and perchlorate  -  and whether label changes could be helpful in keeping their formation down. After discussing the items in the agenda above, Chlorine Institute representatives informed EPA of a 2015 update to National Sanitation Foundation (NSF) Standard 60, which sets health effects criteria for water treatment chemicals to reduce chlorate and perchlorate formation. Chlorine Institute representatives also informed EPA they have drafted a white paper on chlorate and perchlorate minimization practices and committed to providing a summary of the practices as well as information from other regulatory statutes governing chlorate and perchlorate.
EPA will review these practices, as well as those identified by groups, and any recommendations that identify factors that can reduce decomposition of stored sodium hypochlorite solutions and compare the language to existing labeling language on hypochlorite products to assess whether label changes are appropriate. The Chlorine Institute representatives also planned to submit a position statement on the NRDC's proposal to limit the pH of sodium hypochlorite products to less than 12.5 to avoid RCRA requirements.
