              101  PURPOSE:    To limit emissions of perchloroethylene used
                   in dry cleaning.

              110  EXEMPTION, OTHER SOLVENTS:   This rule does not apply to
                   dry   cleaning    equipment    which    does   not   use
                   perchloroethylene.

          200 DEFINITIONS

              201  DRY  CLEANING  MACHINE:  A Dry Cleaning Machine  is  any
                   machine  used to  wash,  extract,  or  dry,  fabrics  or
                   leather using perchloroethylene solvent.

              202  EQUIPMENT:    Any  equipment  using perchloroethylene in
                   the  cleaning  of  fabrics  or  leather  and  associated
                   perchloroethylene  handling  equipment.   The  equipment
                   includes   but  is  not  limited  to;  washers,  dryers,
                   extractors,  filters,  waste  disposal  systems, holding
                   tanks,  pumps, stills, condensers, air handling  systems
                   and attendant piping and valves.

              203  LEAK:   A leak is:
                   203.1   The  visible  presence  of  a  liquid containing
                           perchloroethylene on the external surface of any
                           equipment; or
                   203.2   The concentration of perchloroethylene  vapor in
                           excess  of  100  ppm  as  determined  by methods
                           specified in Section 501.3.

              204  CLOSED  NON-VENTED DRY-TO-DRY SYSTEM:  A system  of  dry
                   cleaning  in which washing, extracting, and drying takes
                   place in one  self  contained  unit  which does not vent
                   perchloroethylene to the atmosphere.

          300 STANDARDS

              301  OPERATING REQUIREMENTS:  A person shall  not operate any
