          B. Requirements  For  Medical  Waste Incinerators That Incinerate
             More Than 25 Tons Of Waste Per Year
             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:
               a.  The dioxins emission have been reduced by 99 percent  or
                   more of the uncontrolled emissions; or
               b.  The  dioxins emissions have been reduced to 10 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  Fahrenheit,
                   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 ( 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:
                                                V
                           Residence Time  = *컴컴*
                                                Qc
                  where:

                   V means 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 degrees Fahrenheit.

                   Qc means the combustion gas flow through V, as expressed
                   in actual cubic  feet  per second, which is measured ac-
                   cording to ARB Method 2,  after  adjusting  the measured
                   flow  rate to the maximum combustion chamber temperature
                   (Tc) by  using  Tc  instead  of  Tstd  in  the  Method 2
                   calculation for Qc.

                   The volumetric flow rate measured at the 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
                   able  unacceptable.   The  determination shall be within
                   the guidelines of Method 2 and  at the discretion of the
                   Air Pollution Control Officer.

                   The calculation of the gas flow rate using the following
                   combustion stoichiometry equation  for  Qc  is  one  al-
                   ternative to measuring the gas flow rate.

                                                       (Tc+460)    1 min
    Qc = {Qstoiwf(1+EAwf/100) + Qstoiaf(1+EAaf/100)} x *컴컴* x *컴컴*
                                                         528      60 sec

                  Where:

            lb-mole  O2       lb  waste       SCF O2       SCF air
  Qstoiwf = *컴컴컴컴컴* x *컴컴컴컴컴* x *컴컴컴컴컴* x *컴컴컴컴컴*

             lb aux. fuel       min.         lb-mole  O2   SCF O2


                  EAwf  =   The   excess   air  (lbs  excess  air  per  lbs
                            theoretical air)  for  the waste feed expressed
                            as a percentage.

                  EAaf  =   The excess air ratio (lbs  excess  air  per 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.


             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 charged to the incinerator.

            5.  For  purposes  of  demonstrating compliance with subsection
                (B)(1) of this rule  the  owner  or  operator  of a medical
                waste  incinerator  shall  conduct a minimum of two  annual
                source tests for the dioxins stack emissions using ARB Test
                Method  428,  using the high resolution  mass  spectrometry
                option. Annual  source  tests  shall  be conducted until at
                least  two  consecutive  tests demonstrate  compliance,  at
                which time the frequency of  future  source tests is at the
                discretion of the Air Pollution Control Officer.

                For  purposes  of  determining compliance  with  subsection
                (B)(1)(a)  of  this  rule,   emissions   shall  be  sampled
                simultaneously  from the flue at a location  downstream  of
                the last combustion  chamber,  but  prior  to  the  control
                equipment, and from the stack during source testing.

                For  purposes  of  determining  compliance  with subsection
                (B)(1)(b)  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.   In those cases where incinerator
                operators are required to submit  information in the permit
                application  on  the  type and quantity  of  waste  burned,
                composition and representativeness  of  the  waste  for the
                compliance  test  will  be  determined  by  inspection  and
                comparison   with   the   permit  application.   When  this
                comparison is not possible,  the  determination of composi-
                tion  and  representativeness  will  be   based  on  source
                generation data and inspection.  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 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.
