      2. (ii) Documentation of the records of the lowest daily residual disinfectant concentration and records of the date and duration of any failure to maintain the Department-prescribed minimum residual disinfectant concentration for more than 4 hours, shall be kept for at least 5 years.
      3. (iii) Documentation of the records of the Department-specified compliance requirements specified by the Department for Department-approved alternative treatment and records of the date and duration of any failure to meet alternative treatment operating requirements for more than 4 hours, shall be kept for at least 5 years.
