to the electricai and instrumentation pians, Two of the panels are associated with ties <br />Chlorination System, The City also requested integration of the Chlorination System into the <br />ourrent design plans.

'File <br />Chlorination System submittal has a Chlorinator PLC Panel. it also has a control <br />description. however, control cicsoription and Chlorinator PLC Panel 10 list are not <br />consistent with the 10 associated with the Chlorinator Remote 10 Panel.
