2.5 Dioxins
dibenzo-p-dioxins and dibenzofurans chlorinated in the 2,3,7, and 8 positions and containing 4,5,6, or 7 chlorine atoms and is expressed as 2,3,7,8 tetrachlorinated dibenzo-para-dioxin equivalents using current California Department of Health Services toxic equivalency factors.

2.6 Facility
every building, structure, appurtenance, installation, or improvement located on land which is under the same or common ownership or operation, and is on one or more contiguous or adjacent properties.

2.7 Medical facilities
medical and dental offices, clinics and hospitals, skilled nursing facilities, research facilities, research laborato-ries, clinical laboratories, all unlicensed and licensed medical facilities, clinics and hospitals, surgery centers, diagnostic laboratories, and other providers of health care.

2.8 Medical waste incinerator
all of the furnaces or other closed fire chambers that are located at a facility and used to dispose of waste generated at medical facilities by burning.

2.9 Uncontrolled emissions
the dioxins emissions measured from the incinerator at a location downstream of the last combustion chamber, but prior to the air pollution control equipment.

2.10 Waste
all discarded putrescible and nonputrescible solid, semisolid, and liquid materials, including garbage, trash, refuse, paper, rubbish, food, ashes, plastics, industrial wastes, demolition and construction wastes, equipment, instruments, utensils, appliances, manure, and human or animal solid and semisolid wastes.

PART 3 REQUIREMENTS
 
3.1 Emission Control Requirements
No person shall operate a medical waste incinerator that incinerates more than 25 tons of waste per year unless:
3.1.1 the dioxins emissions have been reduced by 99 percent or more of the uncontrolled emissions;

3.1.2 the dioxins emissions have been reduced to 10 nanograms or less per kilogram of waste burned.

3.2 Operating Requirements
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 Air Pollution Control Officer to meet the following requirements:
3.2.1 the flue gas temperature at the outlet of the control equipment does not exceed 300 degrees Fahrenheit, unless it has been demonstrated to, and approved in writing by, both the ARB and the Air Pollution Control Officer that lower emissions are achieved at a higher outlet temperature;

3.2.2 for a single chamber incinerator, the combustion chamber is maintained at no less than 1800 degrees (+/- 200 degrees) Fahrenheit;

3.2.3 for a multiple chamber incinerator, the primary combustion chamber is maintained at no less than 1400 degrees Fahrenheit, and the secondary chamber is maintained at no less than 1800 degrees (+/- 200 degrees) Fahrenheit;

3.2.4 the furnace design provides 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:
 
is the volume, in cubic feet, from the point in the incinerator where the maximum temperature has been reached to the point where the temperature has dropped to 1600 F, and
Qc  is the combustion gas flow through V, in actual cubic feet per second, which is measured according 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, and the volumetric flow rate measured at the sampling points must be adjusted to chamber pressures; or alternative methods may be used if conditions for determining 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; 
 
3.2.5 equipment is maintained for determining and recording the weight of waste charged to the incinerator;

3.2.6 the bottom ash, fly ash and scrubber residuals are handled and stored in a manner that prevents entrainment into ambient air;

3.2.7 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; and

3.2.8 copies of the training certificates for the operators and maintenance engineers shall be submitted to the District and the original certificates shall be available for inspection at the facility with the Permit to Operate.

3.3 Monitoring Requirements
The owner or operator of a medical waste incinerator shall maintain a continuous data recording system approved by the District which for each day of operation provides the following:
3.3.1 continuous recording of the primary and secondary combustion chamber temperatures;

3.3.2 continuous recording of carbon monoxide emissions;

3.3.3 the key operating parameters of the air pollution control equipment, as specified by the Air Pollution Control Officer;

3.3.4 the hourly waste charging rates; and

3.3.5 the opacity of stack emissions or other indicator of particulate matter approved by the Air Pollution Control Officer.

3.4 Source Testing Requirements
The owner or operator of a medical waste incinerator shall demonstrate compliance with the control requirements of Section 3.1 of this rule in accordance with the following:
 
3.4.1 A minimum of two annual source tests shall be conducted for the dioxins stack emissions using ARB Test Method 428. 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.

3.4.2 When determining compliance with the 10 nanogram per kilogram of waste emission limit of Section 3.1.2, emissions shall be sampled from the stack using the high resolution mass spectrometry option of ARB Method 428.

3.4.3 When determining compliance with the 99 percent reduction requirement of Section 3.1.1.1, emissions shall be sampled simultaneously at a location downstream of the last combustion chamber, but prior to the control equipment, and from the stack.

3.4.4 Testing shall be conducted during the firing of a representative sample of waste at the maximum waste firing capacity (+/- 10 percent) allowed by the district permit. Information regarding the composition (moisture content, and percent of total waste which 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 Air Pollution Control Officer can require additional necessary information regarding the composition of the waste.

3.4.5 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 District.

3.5 Recordkeeping Requirements
The owner or operator of a medical waste incinerator shall maintain on-site, in a District-approved format, the following information which shall be made available for District inspection upon request for a minimum of three years:
3.5.1 continuous data recording system printouts;

3.5.2 records of the weight of the waste charged to the incinerator;

3.5.3 maintenance records for the incinerator, control equipment, and monitoring equipment; and

3.5.4 calibration records for the monitoring equipment.

3.6 Reporting Requirements
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.
