Meeting Discussion:

The agenda topics discussed at the May 16, 2017 meeting are presented below.

 Next steps in the hypochlorite registration review process
 Discuss path forward to minimize perchlorate and chlorate 
 Best management practices as label changes for registration review
 Residual chlorine at drinking water disinfection utilities 

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 the label changes that could be helpful in keeping their formation down. EPA-OPP will be signing the preliminary interim decision (PID) for the hypochlorites by June 30, 2017. EPA will continue to refine BMP's for perchlorate formation minimization for the PID and will reach out to AWWA again with any questions or big changes.
