KERN COUNTY AIR POLLUTION CONTROL DISTRICT
RULE 418.1 - MEDICAL WASTE INCINERATORS (DIOXIN)
Requirements of this Rule shall apply to any person owning or operating a medical waste incinerator.
A. CARB Test Methods: Test methods as set forth in Sections 94102 (Method 2) and 94139 (Method 428) of the California Code of Regulations.
CARB Test Method 2 means the test method as specified in Title 17, California Code of Regulations, Section 94102.
CARB Test Method 428 means the test method as specified in Title 17, California Code of Regulations, Section 94139.
B. 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 expressed as 2,3,7,8, tetrachlorinated dibenzo-para-dioxin equivalents using current State Office of Environmental Health Hazard Assessment toxic equivalency factors.
C. Facility: Any building, structure, appurtenance, installation, or improvement located on land under common ownership or operation, and on one or more contiguous or adjacent properties.
D. Medical Facilities: Medical and dental offices, clinics and hospitals, skilled nursing facilities, research facilities, research laboratories, clinical laboratories, all unlicensed and licensed medical facilities, clinics and hospitals, surgery centers, diagnostic laboratories, and other providers of health care.
E. Medical Waste Incinerators: Any device located at a facility and used to dispose of waste generated at a medical facility by burning.
F. Uncontrolled Emissions: Dioxins emissions measured from an incinerator at a location downstream of the last combustion chamber, but prior to any air pollution control device.
G. 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.
A. This Rule shall not apply to incinerators exclusively to cremate human or domesticated pet remains.
B. If installation of control equipment is required solely to comply with requirements of this Rule, such equipment shall not be subject to offset requirements of Rule 210.1 (New and Modified Stationary Source Review), provided the system constitutes Best Available Control Technology as defined in Rule 210.1.
A. No person shall operate any medical waste incinerator unless:
B. For medical waste incinerators incinerating more than 10 but less than 25 tons of waste per year, an emissions test, including dioxins, shall be conducted by January 1, 1993.
C. For medical waste incinerators incinerating more than 25 tons of waste per year:
a. By 99 percent or more, or
b. To 10 nanograms or less per kilogram of waste burned.
a. for a single chamber incinerator, the combustion chamber shall be maintained at no less than 1600°F;
b. for a multiple chamber incinerator, the primary combustion chamber shall be maintained at no less than 1400°F; the secondary chamber maintained at no less than 1600°F; and the residence time for combustion gas maintained at no less than one second. Residence time shall be calculated using the following formula:
Residence Time = V
V = volume (ft3) from the point in incinerator where maximum temperature has been reached to point where volume flow temperature has dropped to 1600°F.
Qc = combustion gas volume flowrate through V, (ft3/sec) determined with CARB Test Method 2 and corrected for maximum combustion chamber temperature and pressure.
a. primary and secondary combustion chamber temperatures,
b. carbon monoxide emissions,
c. hourly waste charging rates,
d. opacity of stack emissions, and
e. critical operating parameters of air pollution control equipment.
V. Administrative Requirements
A. Record Keeping
An owner or operator of a medical waste incinerator shall maintain operating records of incinerator, control equipment, monitoring equipment, and calibration records for monitoring equipment. Records shall be retained for two years and made available to District inspectors upon request.
B. Test Methods
Any person subject to Subsection IV.C. shall conduct annual testing to demonstrate compliance. The test report shall be submitted to CARB when submitted to the District and shall be conducted as follows:
a. simultaneously from flue at a location downstream of last combustion chamber, but prior to air pollution control equipment and from stack to demonstrate compliance Requirement IV.C.1.a, or
b. from stack to demonstrate compliance with Requirement IV.C.1.b.
VI. Compliance Schedule
A. Any owner or operator of a medical waste incinerator intending to permanently shut down operation for such incinerator shall notify the District of intention to shut down by December 1, 1992. Shutdown shall be no later than March 1, 1993.
B. Any owner or operator of a medical waste incinerator incinerating 25 tons or less of waste per year intending to remain in operation shall immediately apply for a District Permit to Operate. Such facilities shall be in full compliance with requirements of this Rule by March 1, 1993.
C. Any owner or operator of a medical waste incinerator incinerating more than 25 tons of waste per year shall submit application for an Authority to Construct equipment necessary to meet requirements of this Rule by December 1, 1992. Such facilities shall be in full compliance with the requirements of this Rule by March 1, 1993.
D. Any owner or operator of a medical waste incinerator subject to requirements of this Rule installed or constructed on or after (date of adoption) shall be in full compliance with requirements for this Rule at initial start-up.
