Rule 408d.
(1) A
				  community or noncommunity water supply that is required to monitor source water
				  under 40 CFR 141.701, as adopted by reference in R 325.10720b, shall notify
				  persons served by the water supply that monitoring has not been completed as
				  specified not later than 30 days after the supply has failed to collect any 3
				  months of monitoring as specified in 40 CFR 141.701 (c). The notice shall be
				  repeated as specified in R 325.10403 (2).
(2) A community or noncommunity water supply
				  that is required to determine a bin classification under R 325.10611e shall
				  notify persons served by the water supply that the determination has not been
				  made as required not later than 30 days after the supply has failed to report
				  the determination as specified in R 325.10611e (5). The notice shall be
				  repeated as specified in R 325.10403 (2). The notice is not required if the
				  supply is complying with a department-approved schedule to address the
				  violation.
(3) The form and manner
				  of the public notice shall follow the requirements for a Tier 2 public notice
				  prescribed in R 325.10403 (3). The public notice shall be presented as required
				  in R 325.10405 (3).
(4) The notice
				  shall contain the following language, including the language necessary to fill
				  in the blanks:
(a) The special notice for
				  repeated failure to conduct monitoring shall contain the following language:
				  "We are required to monitor the source of your drinking water for
				  Cryptosporidium. Results of the monitoring are to be used to determine whether
				  water treatment at the [treatment plant name] is sufficient to adequately
				  remove Cryptosporidium from your drinking water. We are required to complete
				  this monitoring and make this determination by [required bin determination
				  date]. We 'did not monitor or test' or 'did not complete all monitoring or
				  testing' on schedule and, therefore, we may not be able to determine by the
				  required date what treatment modifications, if any, shall be made to ensure
				  adequate Cryptosporidium removal. Missing this deadline may, in turn,
				  jeopardize our ability to have the required treatment modifications, if any,
				  completed by the deadline required, [date]. For more information, please call
				  [name of water supply contact] of [name of water supply] at [phone
				  number]."
(b) The special notice
				  for failure to determine bin classification or mean Cryptosporidium level shall
				  contain the following language: "We are required to monitor the source of your
				  drinking water for Cryptosporidium in order to determine by [date] whether
				  water treatment at the [treatment plant name] is sufficient to adequately
				  remove Cryptosporidium from your drinking water. We have not made this
				  determination by the required date. Our failure to do this may jeopardize our
				  ability to have the required treatment modifications, if any, completed by the
				  required deadline of [date]. For more information, please call [name of water
				  supply contact] of [name of water supply] at [phone number]."
(c) Each special notice shall also include a
				  description of what the water supply is doing to correct the violation and when
				  the supply expects to return to compliance or resolve the situation.
