NR 440.76(11)(b)2.2. If your municipal waste combustion unit does not generate steam, or, if your municipal waste combustion units have shared steam systems and steam load cannot be estimated per unit, you shall determine, to the satisfaction of the department, one or more operating parameters that can be used to continuously estimate load level (for example, the feed rate of municipal solid waste or refuse-derived fuel). You shall continuously monitor the selected parameters.
NR 440.76(11)(c)(c) How do I monitor the temperature of flue gases at the inlet of my particulate matter control device? You shall install, calibrate, maintain and operate a device to continuously measure the temperature of the flue gas stream at the inlet of each particulate matter control device.
NR 440.76(11)(d)(d) How do I monitor the injection rate of activated carbon? If your municipal waste combustion unit uses activated carbon to control dioxins/furans or mercury emissions, you shall meet the following 3 requirements:
NR 440.76(11)(d)1.1. Select a carbon injection system operating parameter that can be used to calculate carbon feed rate (for example, screw feeder speed).
NR 440.76(11)(d)2.2. During each dioxins/furans and mercury stack test, determine the average carbon feed rate in kilograms, or pounds, per hour. Also, determine the average operating parameter level that correlates to the carbon feed rate. Establish a relationship between the operating parameter and the carbon feed rate in order to calculate the carbon feed rate based on the operating parameter level.
NR 440.76(11)(d)3.3. Continuously monitor the selected operating parameter during all periods when the municipal waste combustion unit is operating and combusting waste, and calculate the 8-hour block average carbon feed rate in kilograms, or pounds, per hour, based on the selected operating parameter. When calculating the 8-hour block average, do the following 2 things:
NR 440.76(11)(d)3.a.a. Exclude hours when the municipal waste combustion unit is not operating.
NR 440.76(11)(d)3.b.b. Include hours when the municipal waste combustion unit is operating but the carbon feed system is not working correctly.
NR 440.76(11)(e)(e) What is the minimum amount of monitoring data I must collect with my continuous parameter monitoring systems and is the data collection requirement enforceable?
NR 440.76(11)(e)1.1. Where continuous parameter monitoring systems are used, you shall obtain 1-hour arithmetic averages for the following 3 parameters:
NR 440.76(11)(e)1.a.a. Load level of the municipal waste combustion unit.
NR 440.76(11)(e)1.b.b. Temperature of the flue gases at the inlet of your particulate matter control device.
NR 440.76(11)(e)1.c.c. Carbon feed rate if activated carbon is used to control dioxins/furans or mercury emissions.
NR 440.76(11)(e)2.2. You shall obtain at least 2 data points per hour in order to calculate a valid 1-hour arithmetic average.
NR 440.76(11)(e)3.3. You shall obtain valid 1-hour averages for at least 75% of the operating hours per day for 90% of the operating days per calendar quarter. An operating day is any day the unit combusts any municipal solid waste or refuse-derived fuel.
NR 440.76(11)(e)4.4. If you do not obtain the minimum data required in subds. 1. to 3., you are in violation of the data collection requirement and you shall notify the department according to sub. (13) (h) 5.
NR 440.76(12)(12)Recordkeeping.
NR 440.76(12)(a)(a) What records must I keep? You shall keep 5 types of records:
NR 440.76(12)(a)1.1. Materials separation plan and siting analysis.
NR 440.76(12)(a)2.2. Operator training and certification.
NR 440.76(12)(a)3.3. Stack tests.
NR 440.76(12)(a)4.4. Continuously monitored pollutants and parameters.
NR 440.76(12)(a)5.5. Carbon feed rate.
NR 440.76(12)(b)(b) Where must I keep my records and for how long?
NR 440.76(12)(b)1.1. You shall keep all records onsite in paper copy or electronic format unless the department approves another format.
NR 440.76(12)(b)2.2. You shall keep all records on each municipal waste combustion unit for at least 5 years.
NR 440.76(12)(b)3.3. You shall make all records available for submittal to the department, or for onsite review by an inspector.
NR 440.76(12)(c)(c) What records must I keep for the materials separation plan and siting analysis? You shall keep records of the following 5 items:
NR 440.76(12)(c)1.1. The date of each record.
