ME - Monitoring Objective
-------------------------

This transaction captures information about the objective for monitoring this pollutant at this location.

Rules
^^^^^

Every monitor must have an objective.  An objective for a production monitor cannot be deleted if that would leave the monitor without at least one objective.
