NR 440.76(1)(f)(f) How are these new source performance standards structured? These new source performance standards contain the following 5 major components:
NR 440.76(1)(f)1.1. Preconstruction requirements consisting of the following:
NR 440.76(1)(f)1.a.a. Materials separation plan.
NR 440.76(1)(f)1.b.b. Siting analysis.
NR 440.76(1)(f)2.2. Good combustion practices consisting of the following:
NR 440.76(1)(f)2.a.a. Operator training.
NR 440.76(1)(f)2.b.b. Operator certification.
NR 440.76(1)(f)2.c.c. Operating requirements.
NR 440.76(1)(f)3.3. Emission limits.
NR 440.76(1)(f)4.4. Monitoring and stack testing.
NR 440.76(1)(f)5.5. Recordkeeping and reporting.
NR 440.76(1)(g)(g) Do all 5 components of these new source performance standards apply at the same time? No, you shall meet the preconstruction requirements before you commence construction of the municipal waste combustion unit. After the municipal waste combustion unit begins operation, you shall meet all of the good combustion practices, emission limits, monitoring and stack testing requirements and most recordkeeping and reporting requirements.
NR 440.76(1)(h)(h) Are there different subcategories of small municipal waste combustion units within this section?
NR 440.76(1)(h)1.1. Yes, this section subcategorizes small municipal waste combustion units into the following 2 groups based on the aggregate capacity of the municipal waste combustion plant as follows:
NR 440.76(1)(h)1.a.a. Class I units are small municipal waste combustion units that are located at municipal waste combustion plants with an aggregate plant combustion capacity greater than 250 tons per day of municipal solid waste. The definition of “municipal waste combustion plant capacity” in sub. (2) specifies which units at a plant are included in the aggregate capacity calculation.
NR 440.76(1)(h)1.b.b. Class II units are small municipal waste combustion units that are located at municipal waste combustion plants with an aggregate plant combustion capacity less than or equal to 250 tons per day of municipal solid waste. The definition of “municipal waste combustion plant capacity” in sub. (2) specifies which units at a plant are included in the aggregate capacity calculation.
NR 440.76(1)(h)2.2. The requirements for Class I and Class II units are identical except for the following 2 items:
NR 440.76(1)(h)2.a.a. Class I units have a nitrogen oxides emission limit. As indicated in Table 1, Class II units do not have a nitrogen oxides emission limit. Additionally, Class I units have continuous emission monitoring, recordkeeping and reporting requirements for nitrogen oxides.
NR 440.76(1)(h)2.b.b. Class II units are eligible for the reduced testing option provided in sub. (10) (e).
NR 440.76(2)(2)Definitions. All terms used in this section that are not defined in this subsection shall have the meanings given in s. NR 440.02. If the terms are not defined in s. NR 440.02, the terms shall have the meanings given in s. NR 400.02, 40 CFR part 60, subpart B or the Act. In this section:
NR 440.76(2)(a)(a) “Air curtain incinerator” means an incinerator that operates by forcefully projecting a curtain of air across an open chamber or pit in which combustion occurs. Air curtain incinerators can be constructed above or below ground and with or without refractory walls and floor.
NR 440.76(2)(am)(am) “Batch municipal waste combustion unit” means a municipal waste combustion unit designed so it cannot combust municipal solid waste continuously 24 hours per day because the design does not allow waste to be fed to the unit or ash to be removed during combustion.
NR 440.76(2)(b)(b) “Calendar quarter” means 3 consecutive, nonoverlapping months beginning on January 1, April 1, July 1 or October 1.
NR 440.76(2)(c)(c) “Chief facility operator” means the person in direct charge and control of the operation of a municipal waste combustion unit. The chief facility operator is responsible for daily onsite supervision, technical direction, management and overall performance of the municipal waste combustion unit.
NR 440.76(2)(cm)(cm) “Class I units” mean small municipal waste combustion units subject to this section that are located at municipal waste combustion plants with an aggregate plant combustion capacity greater than 250 tons per day of municipal solid waste. The definition in this subsection of “municipal waste combustion plant capacity” specifies which units at a plant site are included in the aggregate capacity calculation.
NR 440.76(2)(d)(d) “Class II units” mean small municipal waste combustion units subject to this section that are located at municipal waste combustion plants with an aggregate plant combustion capacity less than or equal to 250 tons per day of municipal solid waste. The definition in this subsection of “municipal waste combustion plant capacity” specifies which units at a plant site are included in the aggregate capacity calculation.
NR 440.76(2)(dm)(dm) “Clean wood” means untreated wood or untreated wood products including clean untreated lumber, whole or chipped tree stumps and whole or chipped tree limbs. Clean wood does not include yard waste or construction, renovation and demolition wastes, such as railroad ties and telephone poles, that are exempt from the definition of municipal solid waste.
NR 440.76(2)(e)(e) “Co-fired combustion unit” means a unit that combusts municipal solid waste with nonmunicipal solid waste fuel (e.g., coal or industrial process waste). To be considered a co-fired combustion unit, the unit shall be subject to a federally enforceable permit that limits it to combusting a fuel feed stream which is 30% or less, by weight, municipal solid waste as measured each calendar quarter.
NR 440.76(2)(em)(em) “Continuous burning” means the continuous, semicontinuous or batch feeding of municipal solid waste to dispose of the waste, produce energy, or provide heat to the combustion system in preparation for waste disposal or energy production. Continuous burning does not mean the use of municipal solid waste solely to thermally protect the grate or hearth during the startup period when municipal solid waste is not fed to the grate or hearth.
