NR 440.75(2)(s)(s) “Municipal solid waste landfill” or “MSW landfill” means an entire disposal facility in a contiguous geographical space where household waste is placed in or on land. An MSW landfill may also receive other types of wastes defined under 40 CFR 257.2 such as commercial solid waste, nonhazardous sludge, conditionally exempt small quantity generator waste and industrial solid waste. Portions of an MSW landfill may be separated by access roads. An MSW landfill may be publicly or privately owned. An MSW landfill may be a new MSW landfill, an existing MSW landfill, or a lateral expansion.
NR 440.75(2)(t)(t) “Municipal solid waste landfill emissions” or “MSW landfill emissions” means gas generated by the decomposition of organic waste deposited in an MSW landfill or derived from the evolution of organic compounds in the waste.
NR 440.75(2)(u)(u) “NMOC” means nonmethane organic compounds, as measured according to the provisions of sub. (5).
NR 440.75(2)(v)(v) “Nondegradable waste” means any waste that does not decompose through chemical breakdown or microbiological activity. Examples include concrete, municipal waste combustor ash and metals.
NR 440.75(2)(w)(w) “Passive collection system” means a gas collection system that solely uses positive pressure within the landfill to move the gas rather than using gas mover equipment.
NR 440.75(2)(x)(x) “Sludge” means any solid, semisolid or liquid waste generated from a municipal, commercial or industrial wastewater treatment plant, water supply treatment plant or air pollution control facility, exclusive of the treated effluent from a wastewater treatment plant.
NR 440.75(2)(y)(y) “Solid waste” means any garbage, sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility and other discarded material, including solid, liquid, semisolid or contained gaseous material resulting from industrial, commercial, mining, and agricultural operations, and from community activities, but does not include solid or dissolved material in domestic sewage, or solid or dissolved materials in irrigation return flows or industrial discharges that are point sources subject to permits under 33 USC 1342, or source, special nuclear, or by-product material as defined by the Atomic Energy Act, 42 (USC 2011 to 2259).
NR 440.75(2)(ym)(ym) “Sufficient density” means any number, spacing and combination of collection system components, including vertical wells, horizontal collectors, and surface collectors necessary to maintain emission and migration control as determined by measures of performance set forth in this section.
NR 440.75(2)(z)(z) “Sufficient extraction rate” means a rate sufficient to maintain a negative pressure at all wellheads in the collection system without causing air infiltration, including any wellheads connected to the system as a result of expansion or excess surface emissions, for the life of the blower.
NR 440.75(3)(3)Standards for emissions from municipal solid waste landfills.
NR 440.75(3)(a)(a) Each owner or operator of an MSW landfill having a design capacity less than 2.5 million megagrams by mass or 2.5 million cubic meters by volume shall submit an initial design capacity report to the department as provided in sub. (8) (a). The landfill owner or operator may calculate design capacity in either megagrams or cubic meters for comparison with the exemption values. Any density conversions shall be documented and submitted with the report. Submittal of the initial design capacity report shall fulfill the requirements of this section except as follows:

NR 440.75(3)(b)(b) Each owner or operator of an MSW landfill having a design capacity equal to or greater than 2.5 million megagrams and 2.5 million cubic meters, shall either comply with subd. 2. or calculate an NMOC emission rate for the landfill using the procedures specified in sub. (5). The NMOC emission rate shall be recalculated annually, except as provided in sub. (8) (b) 2. The owner or operator of an MSW landfill subject to this section with a design capacity greater than or equal to 2.5 million megagrams and 2.5 million cubic meters is subject to ch. NR 407 permitting requirements.
