                         REGULATION 3 - SECTION 4


         RULE 4-100 - TITLE


             AIRBORNE TOXIC CONTROL MEASURE FOR EMISSIONS OF DIOXINS 
                        FROM MEDICAL WASTE INCINERATORS.


          This regulation is adopted in accordance with the requirements of
          Health and Safety Code Section 39666(d) and of California Code of
          Regulations Section 93104.

                                                     [Adopted May 12, 1992]

          RULE 4-110 - PURPOSE

          In July, 1986, pursuant to Section 39662 of the Health and Safety
          Code, the Air Resources Board (ARB) identified dioxins as a toxic
          air contaminant.  In so identifying dioxins, the Air Resources
          Board found that there is not sufficient available scientific
          evidence to support identification of a threshold exposure level
          below which no significant adverse health effects are anticipated
          (see Title 17, California Code of Regulations, Section 93000).
          In May of 1991, the Office of Administrative law approved the
          Airborne Toxic Control measure for dioxins from medical waste
          incinerators, which is embodied in this regulation.  This
          airborne toxic control measure will reduce emissions of dioxins
          from medical waste incinerators to the lowest level achievable
          through application of best available control technology at
          operations subject to this measure.

          RULE 4-120 - APPLICABILITY

          RULE 4-400 - CONTROL MEASURE FOR EMISSIONS OF DIOXINS FROM
          MEDICAL WASTE INCINERATORS

          (a)  No person shall dispose of medical wastes by burning except in
          a medical waste incinerator which meets the requirements of this
          regulation, and which has been reviewed by the air pollution
          control officer and received a written permit to operate in
          accordance with this and other regulations of the District.
          
          (b)  No person shall operate a category III medical waste
          incinerator unless either condition (1) or (2) is met:

             (1)  Emissions to the atmosphere of dioxins are less than 1
          percent of the uncontrolled emissions of dioxins; or

             (2)  Emissions of dioxins are less than 10 nanograms per
          kilogram of waste burned.

          (c)  No person shall operate a category III medical waste
          incinerator unless control equipment is installed and used in a
          manner which has been demonstrated to and approved by the Air
          Pollution Control Officer to meet all of the following
          conditions, (1) through (4):

             (1)  The temperature of the flue gas at the outlet of the
          control equipment shall not exceed 300 degrees Fahrenheit, unless
          it has been demonstrated to and approved in writing by the Air
          Pollution Control Officer and the ARB that lower emission rates
          are achieved at a higher outlet temperature; and

             (2)  The operating temperature of any single-chamber incinerator
          shall be maintained at not less than 1800 degrees Fahrenheit.

             (3)  The temperature of the primary combustion chamber of any
          multiple-chamber incinerator shall be maintained at not less than
          1400 degrees Fahrenheit, and the temperature of the secondary
          combustion chamber shall be maintained at not less than 1800
          degrees Fahrenheit.

             (4)  The design of any incinerator shall provide that the
          residence time of the combustion gases in the combustion chamber
          of a single-chamber incinerator or in the secondary combustion
          chamber of a multiple-chamber incinerator shall be at least one
          second.  Residence time shall be calculated using Equation 1.

                Residence Time =  V/Qc             (Eqn. 1)
         
                where

                V is the volume, expressed in cubic feet, of that portion of
          the incinerator from the point where the maximum temperature has
          been reached to the point where the temperature has dropped to
          1600 degrees Fahrenheit.

                Qc is the flow rate of combustion gas through the combustion
          chamber, expressed in actual cubic feet per second, and
          determined using ARB Test 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
          flow rate measured at the sampling point must be adjusted to
          chamber pressures.  At the discretion of the Air Pollution
          Control Officer, alternative methods for determining Qc may be
          used if conditions are unacceptable for determining the
          combustion gas flow rate by Method 2.

          RULE 4-410 - RECORD KEEPING EQUIPMENT AT MEDICAL WASTE
          INCINERATORS

          (a)  No person shall operate or cause to be operated a category I
          or II medical waste incinerator unless the incinerator is
          provided with equipment for determining the weight of waste
          charged to the incinerator.

          (b)  No person shall operate or cause to be operated a category III
          medical waste incinerator which is not equipped with an
          automatic, continuous data recording system which provides and
          records, whenever the incinerator is operating, continuous
          recording of the temperatures of the primary and secondary
          combustion chambers and exhaust; carbon monoxide emissions; the
          key operating parameters of the air pollution control equipment,
          as specified by the air pollution control officer; the hourly
          waste charging rate; and the opacity of stack emissions or other
          indicator of emissions of particulate matter which is approved by
          the air pollution control officer.

          (c)  The equipment required by subsections (a) and (b) shall be
          operated whenever the incinerator is operated or charged for
          operation.

          RULE 4-450 - HANDLING OF ASH FROM MEDICAL WASTE INCINERATORS

          No person shall operate or cause to be operated a medical waste
          incinerator unless bottom ash, fly ash and scrubber residuals are
          handled and stored in a manner that prevents entrainment in to
          ambient air.

          RULE 4-460 - OPERATOR TRAINING REQUIREMENTS

          No person shall operate or cause to be operated a medical waste
