VENTURA COUNTY AIR POLLUTION CONTROL DISTRICT

RULE 62.5 - DIOXINS-MEDICAL WASTE INCINERATORS
(Adopted 10/15/91)

A. Applicability

The provisions of this rule shall apply to any operation that uses a medical waste incinerator, except as specified in subsection F.1.

B. Requirements

  1. No person shall operate a medical waste incinerator which incinerates more than 25 tons of waste per year unless all of the following requirements are satisfied:
    1. The emission of dioxins to the atmosphere shall be reduced by at least 99 percent from the uncontrolled emissions, or reduced to 10 nanograms or less per kilogram of waste burned.
    2. The flue gas temperature at the outlet of the control equipment shall not exceed 300 degrees Fahrenheit (oF), unless it has been demonstrated to, and approved in writing by, both the California Air Resources Board and the Air Pollution Control Officer (APCO) that lower emissions are achieved at a higher outlet temperature.
    3. For a single chamber incinerator, the combustion chamber shall be maintained at no less than 1800oF, plus or minus 200oF. For a multiple chamber incinerator, the primary combustion chamber shall be maintained at no less than 1400oF, and the secondary chamber shall be maintained at no less than 1800oF, plus or minus 200oF. The furnace design shall provide for a residence time for combustion gas of at least one second. Residence time shall be calculated using the method presented in Attachment A.
    4. Annual source tests, conducted pursuant to Section G, shall be performed. If two consecutive source tests demonstrate compliance the frequency of future source tests shall be once every four years.
  2. No person shall operate a medical waste incinerator which incinerates more than 10 tons but no more than 25 tons of waste per year unless a single source test is conducted pursuant to Section G.

C. Operating Requirements

No person shall operate a medical waste incinerator unless all of the following requirements are satisfied:

  1. The bottom ash, fly ash and scrubber residuals are handled and stored in a manner that prevents entrainment into the air.

  2. 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 APCO. Copies of the training certificates for the operators and maintenance engineers shall be submitted to the Air Pollution Control District (APCD) and the original certificates shall be available for inspection at the facility with the Permit to Operate.

  3. Equipment for determining the weight of waste charged to the incinerator shall be properly maintained and calibrated.

D. Recordkeeping Requirements

  1. Any person that operates a medical waste incinerator which incinerates more than 25 tons of waste per year shall:
    1. Maintain 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; key operating parameters of the air pollution control equipment, as specified by the APCO; hourly waste charging rates; and the opacity of stack emissions or other indicator of particulate matter which is approved by the APCO.
    2. Maintain maintenance records for the incinerator, control equipment, and monitoring equipment. In addition, calibration records for the monitoring equipment shall be maintained.
  2. Any person that operates a medical waste incinerator shall maintain records of the weight of waste charged to the incinerator for each day the incinerator is operated. In addition, records of all test results shall be maintained.

  3. All records shall be retained for a minimum of two years from the date of entry, with the exception of test results which shall be retained for a minimum of four years. All records shall be made available to the APCO upon request.

E. Reporting Requirements

  1. 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 APCD within 1 hour of occurrence.

  2. Copies of all source test results conducted for the purpose of demonstrating compliance with this rule shall be submitted to the APCD and the California Air Resources Board no later than 10 days after the test results are available.

F. Exemptions

  1. This control measure shall not apply to those incinerators which are exclusively crematoria of human or animal remains.

  2. The requirements of subsections B.1 and D.1 shall not apply to any medical waste incinerator that incinerates 25 tons of waste per year or less, provided that the requirements of subsections D.2 and D.3 are satisfied.

G. Test Methods

  1. Source testing shall be performed using ARB Test Method 428, using the high resolution mass spectrometry option. For the purpose of determining compliance with the 99 percent reduction requirement of subsection B.1.a, 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. For the purpose of determining compliance with the 10 nanogram per kilogram of waste emission limit of subsection B.1.a, or to satisfy the requirements of subsection B.2, emissions shall be sampled at the stack. The feed rate of the fuel charged during the source test and information regarding the composition of the waste including, moisture content, and amount of the total waste that is infectious, pathological, hazardous, or radioactive, shall be provided with the test results. Source testing shall be conducted at the maximum waste firing capacity allowed by the APCD permit, plus or minus 10 percent.

H. Violations

Failure to comply with any provision of this rule, including recordkeeping requirements, shall constitute a violation of this rule.

I. Definitions

  1. "Control equipment": Any device which reduces emissions from medical waste incinerators.

  2. "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.

  3. "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.

  4. "Medical waste incinerators": All of the furnaces or other closed fire chambers that are located at a stationary source and used to dispose of wastes generated at medical facilities by burning.

  5. "Stationary source": As defined in Rule 2 of these Rules.

  6. "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.

  7. "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.

J. Compliance Schedule

The owner or operator of a medical waste incinerator that incinerates more than 25 tons or waste per year shall submit to the APCD an application for an Authority to Construct for the equipment necessary to meet the requirements of subsection B.1.a, no later than January 15, 1992. The owner or operator of medical waste incinerator shall be in compliance with the requirements of this rule no later than January 15, 1993.

  2. The owner or operator of a medical waste incinerator who intends to permanently shutdown operation of the incinerator shall notify the District of the shutdown date no later than January 15, 1992. The shutdown date shall be no later than April 15, 1992.

  3. The owner or operator of a medical waste incinerator that incinerates 25 tons or less of waste per year who intends to remain in operation shall notify the District no later than January 15, 1992.
