Refuse incinerators

1. Applicability. a. The owner or operator of an incinerator of any design capacity for refuse, except trash and refuse derived fuel, must comply with 40 CFR part 60, subpart Ea, which is incorporated by reference in chapter 33.1-15-12. b. Beginning August 1, 1996, no owner or operator of an incinerator for refuse may incinerate materials of any type or form which are recyclable, unless the owner demonstrates to the department that recycling for a waste material is not reasonably available. Documents subject to state or federal privacy regulations may be incinerated when no other acceptable method of disposal is reasonably available. c. Beginning August 1, 1997, each existing incinerator for trash must meet the same standards as a new incinerator for trash. d. As used in this section, "new incinerator" means an incinerator, the construction for which has not been approved by the department prior to August 1, 1995. 2. Existing trash incinerators. This subsection applies to any owner or operator of an incinerator for trash of any design capacity existing on August 1, 1995. a. Prohibited waste. No infectious waste, radioactive waste, hazardous waste, special waste, industrial waste, or any other solid waste may be burned in an incinerator designed for trash unless the incinerator's performance, design, and operating standards for those solid wastes are also met. b. Operator training. The owner or operator of an incinerator for trash shall provide both written and oral instructions for each operator in the proper operation of the incinerator. c. Recordkeeping and reporting. (1) The owner or operator of an incinerator for trash shall keep a log indicating the dates and approximate quantities of waste received from an onsite source, and from each offsite source, including the transporter. The log shall be kept and maintained for a minimum period of three years from the date waste is received. (2) An owner or operator of an incinerator for trash shall record in the log any operational error or failure of one-hour or more duration of combustion equipment, emission control equipment, waste charging equipment, or monitoring equipment. (3) When requested by the department, the owner or operator of an incinerator for trash shall provide a summary of the daily burning and hours of operation. 3. New trash incinerators. In addition to subsection 2, this subsection applies to an owner or operator of a new incinerator for trash. a. Design. Each new incinerator for trash must be equipped with a primary combustion chamber or zone which provides complete combustion of solid waste and a secondary combustion chamber or zone which provides turbulent mixing. Auxiliary fuel burners are required in all chambers. The department may approve an alternate design provided the design achieves the performance requirements of this section. b. Opacity. No owner or operator of a new incinerator for trash may allow to be discharged into the atmosphere any air contaminant which exhibits an opacity greater than ten percent except that a maximum of twenty percent opacity is permissible for not more than one 6-minute period per hour. c. Operating temperature. Each new incinerator for trash shall maintain the flue gas temperature in the secondary combustion chamber or zone at one thousand five hundred degrees Fahrenheit [815 degrees Celsius] or greater for a minimum of one-half-second retention time. d. Monitoring. Each new incinerator for trash shall be equipped with a continuous temperature monitor, with readout, to monitor the temperature of the gases exiting the secondary combustion chamber or zone. e. Stack height. Each new incinerator for trash shall be equipped with a stack for the discharge of flue gases of sufficient height to prevent ambient concentrations of air contaminants greater than allowed by chapter 33.1-15-02. The minimum stack height is forty feet [12.2 meters] unless it is demonstrated that a stack height less than forty feet [12.2 meters] will meet the standards of chapter 33.1-15-02. The department may require taller stacks when it is necessary to meet the standards of chapter 33.1-15-02. f. Waste charging. (1) The waste charging system for a new incinerator for trash must be designed to prevent disruption of the combustion process as waste is charged. (2) The waste charging system must be designed to prevent overcharging to assure complete combustion. No owner or operator may cause an incinerator for trash to operate at a load greater than one hundred percent of design capacity.
