          C.   REQUIREMENTS FOR MEDICAL WASTE INCINERATORS
               The following requirements shall apply only to medical waste
               incinerators  that incinerate more than 25 tons of waste per
               year.
               
               1.   No person  shall  operate  a  medical waste incinerator
                    unless the dioxins emissions have been reduced to 10.00
                    nanograms or less per kilogram of waste burned.

               2.   No  person  shall operate a medical  waste  incinerator
                    unless the control equipment is installed and used in a
                    manner which  has  been demonstrated to and approved by
                    the district air pollution  control officer to meet the
                    following requirements:

                    A.   The flue gas temperature  at  the  outlet  of  the
                         control  equipment  shall  not  exceed 300 degrees
                         ahrenheit, unless it has been demonstrated to, and
                         approved  in  writing  by, both the  ARB  and  the
                         district air pollution control  officer that lower
                         emissions   are   achieved  at  a  higher   outlet
                         temperature; and

                    B.   For a single chamber  incinerator,  the combustion
                         chamber shall be maintained at no less  than  1800
                         degrees  (+  or  -  200 degrees) Fahrenheit. For a
                         multiple   chamber   incinerator,    the   primary
                         combustion chamber shall be maintained  at no less
                         than  1400  degrees  Fahrenheit, and the secondary
                         chamber shall be maintained  at  no less than 1800
                         degrees (+ 200 degrees) Fahrenheit.   The  furnace
                         design  shall  provide  for  a  residence time for
                         combustion  gas of at least one second.  Residence
                         time  shall  be  calculated  using  the  following
                         equation:

          Residence Time =   V
                           -----
                             Qc

          where:

               V =  the volume, as expressed  in cubic feet, from the point
                    in the incinerator where the  maximum  temperature  has
                    been  reached until the point where the temperature has
                    dropped to 1600 F.

               Qc = the combustion  gas  flow through V expressed in actual
                    cubic feet per second,  which  is measured according to
                    ARB Method 2, after adjusting the measured flow rate to
                    the maximum furnace temperature  (Tmax)  by  using Tmax
                    instead of Tstd in the Method 2 calculation for  Qc, as
                    follows:

                    The  volumetric  flow  rate  measured  at  the sampling
                    points must be adjusted to chamber pressures.

                    Alternative  methods  may  be  used  if conditions  for
                    determining the combustion gas flow rate  by  Method  2
                    are  unacceptable.   The  determination shall be within
                    the guidelines of Method 2 and at the discretion of the
                    Air Pollution Control Officer.  One such alternative is
                    to   calculate   the   flow   rate    from   combustion
                    stoichiometry according to following equation

          Qc = {Qstoiwf (1+EAwf/100) + Qstoiwf (1+EAaf/100)}x (Tc
          + 460)x 1 min

          528        60 sec

           Where:

          Qstoiwf = Lb-mole 02  x  Lb waste  x  SCF 02  x  SCF air
                       Lb waste         min.        Lb-mole 02    SCF 02


          Qstoiaf = Lb-mole 02  x  Lb aux. fuel  x  SCF 02  x  SCF air
                         Lb   aux.   fuel          min.        Lb-mole   02
          SCF02

          Eawf   =   The excess air ratio (Lbs excess air --- Lbs
          theoretical air) for the waste feed expressed
                      as a percentage


          EAaf  =  The excess air ratio (Lbs excess air --- Lbs theoretical
          air) for the auxiliary fuel
          expressed as a percentage

          Tc = The maximum temperature, in degrees Fahrenheit, that
          has been reached in the incinerator

               In order to estimate Qstoiwf  and  EAwf,  a   representative
               sample  of  the  waste  must  be  characterized  by chemical
               analysis.    If  chemical   analysis  is not performed,  the
               applicant  must provide evidence to substantiate  claims  of
               representativeness  of  any  proposed  empirical  method  to
               estimate   Qstoiwf   and   EAwf,   since  determining  these
               parameters  empirically can result in less accurate values.

          3.   No person shall operate a medical waste  incinerator  unless
               the  bottom  ash, fly ash and scrubber residuals are handled
               and  stored in  a  manner  that  prevents  entrainment  into
               ambient air.
          
          4.   The owner  or  operator of a medical waste incinerator shall
               maintain the following:

               A.   A continuous  data  recording system which provides for
                    each  day  of operation  continuous  recording  of  the
                    primary and  secondary combustion chamber temperatures;
                    carbon monoxide emissions; the key operating parameters
                    of the air pollution control equipment, as specified by
                    the district air  pollution control officer; the hourly
                    waste  charging  rates;   and   the  opacity  of  stack
                    emissions  or  other  indicator  of particulate  matter
                    which is approved by the district air pollution control
                    officer;

               B.   Maintenance   records  for  the  incinerator,   control
                    equipment, and  monitoring  equipment;  and calibration
                    records for the monitoring equipment; and

               C.   Equipment for determining and recording the  weight  of
                    waste charge to the incinerator.

          5.   For  purposes  of  demonstrating  compliance with subsection
               (c)(1) of this rule the owner or operator of a medical waste
               incinerator shall conduct a minimum  of  two  annual  source
               tests  every year for the dioxins stack emissions using  the
               high resolution  mass spectrometry option of ARB Test Method
               428. For purposes  of determining compliance with subsection
               (c)(l) of this rule,  the  source testing shall be conducted
               at  the  stack. The information  regarding  the  composition
               (moisture  content,  and  amount  of the total waste that is
               infectious,  pathological, hazardous,  or  radioactive)  and
               feed rate of the  fuel  charged during the source test shall
               be  provided  with  the  test   results.  The  district  air
               pollution control officer can require  additional  necessary
               information  regarding the composition of the waste.  Source
               testing shall  be  conducted  at  the  maximum  waste firing
               capacity (+ 10 percent) allowed by the air district  permit.
               A copy of all source test results conducted for purposes  of
               demonstrating compliance with this rule shall be provided to
               the  ARB  at  the same time that it is provided to the local
               air pollution control district.

          6.   Any  violation,  malfunction,  or  upset  condition  on  the
               incinerator,  the  air  pollution  control equipment, or the
               continuous data recording system shall  be  reported  to the
               district  within  1  hour  of occurrence or by 9:OO a.m. the
               next business day if the malfunction  occurs  outside normal
               business  hours and the district does not maintain  a  radio
               room or an answering machine.

          7.   No person shall  operate  a medical waste incinerator unless
               each individual who operates  or  maintains  the incinerator
               obtains  either  a certificate of training in medical  waste
               incineration issued  by  the  American Society of Mechanical
               Engineers  within nine months of  the  commencement  of  the
               training program,  or  equivalent  training as determined by
               the Air Pollution Control Officer. Copies  of  the  training
               certificates  for  the  operators  and maintenance engineers
               shall  be  submitted  to  the  districts  and  the  original
               certificates  shall  be  available  for  inspection  at  the
               facility with the permit to operate.
