RULE 432. PERCHLOROETHYLENE DRY CLEANING OPERATIONS
               (Adopted 5/24/95)

     A.   APPLICABILITY.  The provisions of this Rule shall apply to any 
          person who owns or operates perchloroethylene dry cleaning 
          equipment.

     B.   DEFINITIONS.  For the purposes of this Rule, the following 
          definitions shall apply:

          1.   "Adsorptive Cartridge Filter":  A replaceable cartridge filter 
               that contains diatomaceous earth or activated clay as the 
               filter medium.

          2.   "Cartridge Filter": A replaceable cartridge filter that 
               contains one of the following as the filter medium:  paper, 
               activated carbon, or paper and activated carbon.  A cartridge 
               filter contains no diatomaceous earth or activated clay.  
               Cartridge filters include, but are not limited to:  standard 
               filters, split filters, "jumbo" filters, and all carbon 
               polishing filters.

          3.   "Closed-Loop Machine": Any dry cleaning equipment, sometimes 
               known as dry-to-dry, in which washing, extraction, and drying 
               are all performed in the same single unit and which recircu-
               lates perchloroethylene-laden vapor through a primary control 
               system with no exhaust to the atmosphere during the drying
               cycle.  A closed-loop machine may allow for venting to the 
               ambient air through a fugitive control system after the drying 
               cycle is complete and only while the machine door is open.

          4.   "Co-Located with a Residence": Sharing a common wall, floor, 
               or ceiling with a residence.  For the purposes of this 
               definition, "residence" means any dwelling or housing which is 
               owned, rented, or occupied by the same person for a period of
               less than 180 calendar days or more excluding short-term 
               housing such as a motel or hotel room rented and occupied by 
               the same person for a period of less than 180 calendar days.

          5.   "Converted Machine": An existing vented machine that has been 
               modified to be a closed-loop machine by eliminating the 
               aeration step, installing a primary control system, and 
               providing for recirculation of the perchloroethylene-laden 
               vapor with no exhaust to the atmosphere or workroom during the 
               drying cycle.  A converted machine may allow for venting to 
               the ambient air through a fugitive control system after the 
               drying cycle is complete and only while the machine door is 
               open.

          6.   "Cool-Down": The portion of the drying cycle that begins when 
               the heating mechanism deactivates and the refrigerated 
               condenser continues to reduce the temperature of the air 
               recirculating through the drum to reduce the concentration of 
               perchloroethylene in the drum.

          7.   "Date of Compliance": The time from October 1, 1994, until a

          8.   "Desorption": Regeneration of an activated carbon bed, or any 
               other type of vapor adsorber by removal of the adsorbed 
               solvent using hot air, steam, or other means.

          9.   "Dip Tank Operations": The immersion of materials in a 
               solution that contains perchloroethylene, for purposes other 
               than dry cleaning, in a tank or container that is separate 
               from the dry cleaning equipment.

                    checklist to the facility.  Each operation and maintenance 
                    function and the date performed shall be recorded on the 
                    checklist.  The operation and maintenance checklist 
                    provided by the District shall include, at a minimum, the 
                    following requirements:

                    1)   Refrigerated condensers shall be operated to ensure 
                         that exhaust gases are recirculated until the 
                         air-vapor stream temperature on the outlet side of 
                         the refrigerated condenser, downstream of any bypass, 
                         is less than or equal to 45oF (7.2oC).

                    2)   Primary control systems, other than refrigerated 
                         condensers, shall be operated to ensure that exhaust 
                         gases are recirculated until the perchloroethylene 
                         concentration in the drum is less than or equal to
                         8,600 ppmv at the end of the drying cycle, before 
                         the machine door is opened and any fugitive control 
                         system activates.

                    3)   Vapor adsorbers used as a primary control system or 
                         secondary control system shall be operated to ensure 
                         that exhaust gases are recirculated at the 
                         temperature specified by the District, based on the
                         manufacturer's recommendations for optimum 
                         adsorption.  These vapor adsorbers shall be desorbed 
                         according to the conditions specified by the 
                         District in the facility's operating permit, 
                         including a requirement that no perchloroethylene 
                         vapors shall be routed to the atmosphere during 
                         routine operation or desorption.

                    4)   During the interim period between compliance with 
                         this Subsection and compliance with the requirements 
                         of Subsection G, an existing facility with a 
                         transfer machine or a vented machine shall operate 
                         any existing carbon adsorber, which functions during 
                         the drying cycle, to meet the following requirements:

                         i.   Desorption shall be performed periodically, at 
                              the frequency specified by the District.  The 
                              frequency, at a minimum, shall be each time all 
                              dry cleaning equipment exhausted to the device 
                              has cleaned a total of three pounds of materials 
                              for each pound of activated carbon.  Desorption 
                              shall be performed with the minimum steam 
                              pressure and air flow capacity specified by the
                              District.

                         ii.  Once desorption is complete, the carbon bed 
                              shall be fully dried according to the 
                              manufacturer's instructions.

                         iii. No vented perchloroethylene vapors shall bypass 
                              the carbon adsorber to the atmosphere.

                    5)   Cartridge filters and adsorptive cartridge filters 
                         shall be handled using one of the following methods.

                         i.   Drained in the filter housing, before disposal, 
                              for no less than:  24 hours for cartridge 
                              filters and 48 hours for adsorptive cartridge 
                              filters.  If the filters are then transferred 
                              to a separate device to further reduce the 
                              volume of perchloroethylene, this treatment 
                              shall be done in a system that routes any vapor 
                              to a primary control system, with no exhaust to 
                              the atmosphere or workroom.

                         ii.  Dried, stripped, sparged, or otherwise treated, 
                              within the sealed filter housing, to reduce the 
                              volume of perchloroethylene contained in the 
                              filter.

                    6)   A still, and any muck cooker, shall not be allowed 
                         to exceed 75 percent of its capacity, or an 
                         alternative level recommended by the manufacturer.  
                         A still, and any muck cooker, shall be cooled to 
                         100oF (38oC) or less before being emptied or cleaned.
                         
                    7)   Button and lint traps shall be cleaned each working 
                         day and the lint placed in a tightly sealed 
                         container.

                    8)   All parts of the dry cleaning system where 
                         perchloroethylene may be exposed to the atmosphere 
                         or workroom shall be kept closed at all times except 
                         when access is required for proper operation and
                         maintenance.

                    9)   Waste water evaporators shall be operated to ensure 
                         that no liquid perchloroethylene or visible emulsion 
                         is allowed to vaporize.

          2.   Leak Check and Repair Requirements.  The trained operator, or 
               her/his designee, shall inspect the dry cleaning system for 
               liquid leaks and perceptible vapor leaks beginning on the 
               applicable date shown in Column 5 of Table 432-1.  The trained
               operator, or her/his designee, shall inspect the dry cleaning 
               system for vapor leaks instead of perceptible vapor leaks 
               beginning April 1, 1996. The District shall provide a leak 
               inspection checklist to the facility.  The trained operator, 
               or her/his designee, shall record the status of each component 
               on the checklist.               
               
               a.   The dry cleaning system shall be inspected at least once 
                    per week for liquid leaks and:

                    1)   For perceptible vapor leaks, beginning on the 
                         applicable date shown in Column 5 of Table 432-1 
                         until April 1, 1996.

                    2)   For vapor leaks, beginning April 1, 1996, using one 
                         of the following techniques:

                         i.   A halogenated-hydrocarbon detector.

                         ii.  A portable gas analyzer or an alternative 
                              method approved by the District.

               b.   Any liquid leak, perceptible vapor leak, or vapor leak 
                    that has been detected by the operator shall be noted 
                    on the checklist and repaired according to the 
                    requirements of this Subsection.  If the leak is not 
                    repaired at the time of detection, the leaking component 
                    shall be physically marked or tagged in a manner that is 
                    readily observable to a District inspector.

               c.   Any liquid leak, perceptible vapor leak, or vapor leak 
                    detected by the District, which has not been so noted on 
                    the checklist and marked on the leaking component of the 
                    dry cleaning system, shall constitute a violation of this 
                    Section.  For enforcement purposes, the District shall:

                    1)   Identify the presence of a perceptible vapor leak 
                         based on the odor of perchloroethylene or the 
                         detection of gas flow by passing the fingers over 
                         the surface of the system.

                    2)   Identify the presence of a vapor leak by determining 
                         the concentration of perchloroethylene with a 
                         portable analyzer:

                         i.   According to ARB Test Method 21.

                         ii.  Measured 1 cm. away from the dry cleaning 
                              system.

               d.   Any liquid leak or vapor leak shall be repaired within 
                    24 hours of detection.

                    1)   If repair parts are not available at the facility, 
                         the parts shall be ordered within two working days 
                         of detecting such a leak.  Such repair parts shall 
                         be installed within five working days after receipt.  
                         A facility with a leak that has not been repaired by 
                         the end of the 15th working day after detection 
                         shall not operate the dry cleaning equipment, until 
                         the leak is repaired, without a leak-repair 
                         extension from the District.                    
                         
                    2)   A District may grant a leak-repair extension to a 
                         facility, for a single period of 30 calendar days or 
                         less, if the District makes these findings:

                         i.   The delay in repairing the leak could not have 
                              been avoided by action on the part of the 
                              facility.

                         ii.  The facility used reasonable preventive 
                              measures and acted promptly to initiate the 
                              repair.

                         iii. The leak would not significantly increase 
                              perchloroethylene exposure near the facility.

                         iv.  The facility is in compliance with all other 
                              requirements of this Section and has a history 
                              of compliance.

          3.   Environmental Training Requirements.  The facility shall have 
               one or more trained operators beginning on the applicable date 
               shown in Column 6 of Table 432-1.

               a.   A trained operator shall be the owner, the operator, or 
                    another employee of the facility, who successfully 
                    completes the initial course of an environmental training 
                    program to become a trained operator.  Evidence of
                    successful completion of the initial course shall be the 
                    original record of completion issued pursuant to Title 17 
                    CCR, Section 93110.  The trained operator shall be a 
                    full-time employee of the facility.  Except for the 
                    provisions of Subsection F.3.c.2, one person cannot serve 
                    as the trained operator for two or more facilities 
                    simultaneously.

               b.   Each trained operator shall successfully complete the 
                    refresher course of an environmental training program at 
                    least once every three years.  Evidence of successful 
                    completion of each refresher course shall be the date of 
                    the course and the instructor's signature on the original 
                    record of completion.

               c.   If the facility has only one trained operator and the 
                    trained operator leaves the employ of the facility, the 
                    facility shall:

                    1)   Notify the District in writing within 30 calendar 
                         days of the departure of the trained operator.

                    2)   Obtain certification for a replacement trained 
                         operator within 3 months, except that a trained 
                         operator who owns or manages multiple facilities 
                         may serve as the interim trained operator at two of 
                         those facilities simultaneously for a maximum period 
                         of 4 months, by which time each facility must have 
                         its own trained operator.

                    3)   If the District determines that the initial course 
                         of an environmental training program is not 
                         reasonably available, the District may extend the 
                         certification period for a replacement trained 
                         operator until 1 month after the course is 
                         reasonably available.

     G.   EQUIPMENT.  The owner/operator shall not operate dry cleaning 
          equipment after the applicable date shown in Column 7 of Table 
          432-1, unless the following requirements are met:

          2.   For compliance with Subsection F.3, "Environmental Training 
               Requirements", an alternative date of compliance shall apply 
               if the District determines that the initial course of an

               cleaning operations is not reasonably available.

               a.   For existing facilities in the District, if the initial 
                    course is not reasonably available by April 1, 1996, the 
                    alternative date of compliance for Subsection F.3 only 
                    shall be six (6) months from the date the District

                    available.

               b.   For each new facility in the District, if the initial 
                    course is not reasonably available within the period 
                    from three (3) months prior until two (2) months 
                    following commencement of operation, the alternative

                    one (1) month from the date the District determines that 
                    the initial course is reasonably available.
