				  Notwithstanding subsection (a), systems may increase residual disinfectant
				  levels of chlorine or chloramines (but not chlorine dioxide) in the
				  distribution system in excess of the levels specified in table 64533.5-A in
				  order to protect public health, to address specific microbiological

				  distribution line breaks, storm run-off events, source water contamination
				  events, natural disasters, or cross-connection events. In such circumstances,
				  systems shall immediately notify the State Board of the source and cause of
				  contamination, the levels of residual disinfectant, other actions being taken
				  to correct the problem, and the expected duration of the exceedance.
