If any trigger has been exceeded, systems must complete assessments as required by R309-211-8.

  (b) A seasonal system must monitor every month that it is in operation.

  (c) The Director may exempt any seasonal system from some or all of the requirements for seasonal systems if the entire distribution system remains pressurized during the entire period that the system is not operating.
