          200 DEFINITIONS

              201  SOLVENT RECOVERY  DRYER:  A class of dry cleaning dryers
                   that employs a condenser  to liquify and recover solvent
                   vapors evaporated in a closed  loop recirculating stream
                   of heated air.

          300 STANDARDS

              301  OPERATING REQUIREMENTS:  A person  shall not operate any
                   dry   cleaning   equipment  which  uses  petroleum-based
                   solvent unless:
                   301.1   There is no  liquid  leaking from any portion of
                           the equipment.
                   301.2   Solvents are stored in  closed  containers only,
                           which may be equipped with vents approved by the
