NR 440.647NR 440.647 Volatile organic compound (VOC) emissions from the polymer manufacturing industry. NR 440.647(1)(1) Applicability and designation of affected facilities. NR 440.647(1)(a)(a) The provisions of this section apply to affected facilities involved in the manufacture of polypropylene, polyethylene, polystyrene, or poly(ethylene terephthalate) as defined in sub. (2). The affected facilities designated as follows for polypropylene and polyethylene are inclusive of all equipment used in the manufacture of these polymers, beginning with raw materials preparation and ending with product storage, and cover all emissions emanating from such equipment: NR 440.647(1)(a)1.1. For process emissions from any polypropylene and polyethylene manufacturing process that uses a continuous process, the affected facilities are each of the following process sections: each raw materials preparation section, each polymerization reaction section, each material recovery section, each product finishing section and each product storage section. These process sections are affected facilities for process emissions that are emitted continuously and for process emissions that are emitted intermittently. NR 440.647(1)(a)2.2. For process emissions from polystyrene manufacturing processes that use a continuous process, the affected facilities are each material recovery section. These process sections are affected facilities for only those process emissions that are emitted continuously. NR 440.647(1)(a)3.3. For process emissions from poly(ethylene terephthalate) manufacturing processes that use a continuous process, the affected facilities are each polymerization reaction section. If the process uses dimethyl terephthalate, then each material recovery section is also an affected facility. If the process uses terephthalic acid, then each raw materials preparation section is also an affected facility. These process sections are affected facilities for only those process emissions that are emitted continuously. NR 440.647(1)(a)4.4. For VOC emissions from equipment leaks from polypropylene, polyethylene and polystyrene (including expandable polystyrene) manufacturing processes, the affected facilities are each group of fugitive emissions equipment, as defined in sub. (2), within any process unit, as defined in sub. (2). This section does not apply to VOC emissions from equipment leaks from polyethylene terephthalate manufacturing processes. NR 440.647(1)(a)4.a.a. Affected facilities with a design capacity to produce less than 1,000 Mg/yr (1,102 ton/yr) shall be exempt from sub. (4). NR 440.647(1)(a)4.b.b. Addition or replacement of equipment for the purposes of improvement which is accomplished without a capital expenditure will not by itself be considered a modification under sub. (4). NR 440.647(1)(b)(b) The applicability date identifies when an affected facility becomes subject to a standard. Usually, a standard has a single applicability date. However, some polypropylene and polyethylene affected facilities have a September 30, 1987, applicability date and others have a January 10, 1989, applicability date. The following paragraphs identify the applicability dates for all affected facilities subject to this section. NR 440.647(1)(b)1.1. Polypropylene and polyethylene. Each process section in a polypropylene or polyethylene production process is a potential affected facility for both continuous and intermittent emissions. The applicability date depends on when the process section was constructed, modified or reconstructed and, in some instances, on the type of production process. NR 440.647(1)(b)1.a.a. The applicability date for any polypropylene or polyethylene affected facility that is constructed, modified or reconstructed after January 10, 1989, regardless of the type of production process being used, is January 10, 1989. NR 440.647(1)(b)1.b.b. Only some polypropylene or polyethylene process sections that are constructed, modified or reconstructed on or before January 10, 1989, but after September 30, 1987, are affected facilities. These process sections, and the type of emissions to be controlled, are identified by an “X” in Table 1. The applicability date for the process sections and the emissions to be controlled that are identified by an ‘X’ in Table 1 is September 30, 1987. Since the affected facilities that have a September 30, 1987, applicability date are determined by the type of production process (for example, liquid phase, gas phase), each owner or operator shall identify the particular production process that applies to his or her particular process. NR 440.647 NoteNote: “X” denotes that process section is an affected facility for continuous or intermittent emissions or both, as shown, which has a September 30, 1987, applicability date.
NR 440.647 Note“—” denotes that process section is not considered an affected facility for continuous or intermittent emissions or both, as shown, if the process section is constructed, modified, or reconstructed after September 30, 1987, and on or before January 10, 1989. These process sections are affected facilities if they are constructed, modified, or reconstructed after January 10, 1989.
NR 440.647(1)(b)2.2. Polystyrene. The applicability date for each polystyrene affected facility is September 30, 1987. NR 440.647(1)(b)3.3. Poly(ethylene terephthalate). The applicability date for each poly(ethylene terephthalate) affected facility is September 30, 1987. NR 440.647(1)(c)(c) Any facility under par. (a) that commences construction, modification or reconstruction after its applicability date as identified under par. (b) is subject to the requirements of this section, except as provided in par. (d) to (f). NR 440.647(1)(d)(d) Any polypropylene or polyethylene affected facility with a September 30, 1987, applicability date that commenced construction, modification or reconstruction after September 30, 1987, and on or before January 10, 1989, with an uncontrolled emission rate, as defined in footnote a to Table 2, at or below those identified in Table 2 is not subject to the requirements of sub. (3) unless and until its uncontrolled emission rate exceeds that rate listed for it in Table 2 or it is modified or reconstructed after January 10, 1989. At such time, such facility becomes subject to sub. (3) and the procedures identified in sub. (3) (a) shall be used to determine the control of emissions from the facility. a “Uncontrolled emission rate” refers to the emission rate of a vent stream that vents directly to the atmosphere and to the emission rate of a vent stream to the atmosphere that would occur in the absence of any add-on control devices but after any material recovery devices that constitute part of the normal material recovery operations in a process line where potential emissions are recovered for recycle or resale.
b Emission rate applies to continuous emissions only.
c Emission rate applies to intermittent emissions only.
d Total emission rate for non-emergency intermittent emissions from raw materials preparation, polymerization reaction, material recovery, product finishing, and product storage process sections.
e See footnote d.
f Emission rate applies to both continuous and intermittent emissions.
g Emission rate applies to non-emergency intermittent emissions only.
h Applies to modified or reconstructed affected facilities only.
i Includes emissions from the cooling water tower.
j Applies to a process line producing low viscosity poly(ethylene terephthalate).
k Applies to a process line producing high viscosity poly(ethylene terephthalate).
l See footnote m.
m Applies to the sum of emissions to the atmosphere from the polymerization reaction section (including emissions from the cooling water tower) and the raw materials preparation section (i.e., the esterifiers).
NR 440.647(1)(e)1.1. Modified or reconstructed affected facilities at polystyrene and poly(ethylene terephthalate) plants with uncontrolled emission rates at or below those identified in Table 2 are exempt from the requirements of sub. (3) unless and until its uncontrolled emission rate exceeds that rate listed for it in Table 2. This exemption does not apply to new polystyrene or poly(ethylene terephthalate) affected facilities. NR 440.647(1)(e)2.2. Emissions from modified or reconstructed affected facilities that are controlled by an existing control device and that have uncontrolled emission rates greater than the uncontrolled threshold emission rates identified in Table 2 are exempt from the requirements of sub. (3) unless and until the existing control device is modified, reconstructed or replaced. NR 440.647(1)(f)(f) No process section of an experimental process line is considered an affected facility for continuous or intermittent process emissions. NR 440.647(1)(g)(g) Individual vent streams that emit continuous emissions with uncontrolled annual emissions of less than 1.6 Mg/yr or with a weight percent TOC of less than 0.10% from a new, modified or reconstructed polypropylene or polyethylene affected facility are exempt from the requirements of sub. (3) (a) 1. If at a later date, an individual stream’s uncontrolled annual emissions become 1.6 Mg/yr or greater, if the stream was exempted on the basis of the uncontrolled annual emissions exemption, or VOC concentration becomes 0.10 weight percent or higher, if the stream was exempted on the basis of the VOC concentration exemption, then the stream is subject to the requirements of sub. (3). NR 440.647(1)(h)(h) Emergency vent streams, as defined in sub. (2) from a new, modified or reconstructed polypropylene or polyethylene affected facility are exempt from the requirements of sub. (3) (a) 2. NR 440.647(1)(i)(i) An owner or operator of a polypropylene or polyethylene affected facility that commenced construction, modification or reconstruction after September 30, 1987, and on or before January 10, 1989, and that is in a process line in which more than one type of polyolefin, that is, polypropylene, low density polyethylene, high density polyethylene or their copolymers, is produced shall select one of the polymer/production process combinations in Table 1 for purposes of determining applicable affected facilities and uncontrolled threshold emission rates. NR 440.647 NoteNote: The numerical emission limits in these standards are expressed in terms of total organic compounds, measured as total organic compounds less methane and ethane.
