I believe the following is excellent except the date limitation and the exclusion of psychiatrists as an option.  If other disciplines don't allow LPC.LMFT supervision, that's their limitation.  It doesn't have to be ours. 
Current Code:  "At least 100 hours of the supervision shall be rendered by a licensed professional counselor. Supervisors who are substance abuse treatment practitioners, school psychologists, clinical psychologists, clinical social workers, or psychiatrists and have been approved to provide supervision may continue to do so until August 24, 2017."
