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.

NR 440.647(1)(j)1.1. Owners or operators may choose to comply with 40 CFR part 65, subpart G, as in effect on December 14, 2000, for continuous process vents that are subject to this section, that choose to comply with sub. (3) (a) 1. a. 1), 2) or 3) as allowed in sub. (3) (a) 1. and (b) 1. c. The requirements of 40 CFR part 65, subpart G, as in effect on December 14, 2000, satisfy the requirements of par. (c) and subs. (5) to (7), except for sub. (7) (g) 1. Other provisions applying to owners or operators who choose to comply with 40 CFR part 65, subpart G, as in effect on December 14, 2000, are provided in 40 CFR 65.1

NR 440.647(1)(j)2.2. Owners or operators who choose to comply with 40 CFR part 65, subpart G, as in effect on December 14, 2000, shall also comply with ss. NR 440.01, 440.02, 440.05, 440.06, 440.07 (1) (a) and (d), 440.14 and 440.15 for those process vents. All sections or subsections from ss. NR 440.01 to 440.19 not specified in this subdivision do not apply to owners or operators of process vents complying with 40 CFR part 65, subpart G, except that provisions required to be met prior to implementing 40 CFR part 65 still apply. Owners or operators who choose to comply with 40 CFR part 65, subpart G, as in effect on December 14, 2000, shall comply with 40 CFR part 65, subpart A.

NR 440.647(1)(j)3.3. Each owner or operator subject to the provisions of this section that chooses to comply with 40 CFR part 65, subpart G, as in effect on December 14, 2000, at initial startup shall notify the administrator of the specific provisions of 40 CFR part 65, subpart G, as in effect on December 14, 2000, with which the owner or operator has elected to comply. Notification shall be submitted with the notification of initial startup required by 40 CFR 65.5 (b).

NR 440.647(2)(a)(a) As used in this section, all terms not defined shall have the meaning given them in s. NR 440.02 or in s. NR 440.62, and the following terms shall have the specific meanings given them.

NR 440.647(2)(a)2.2. “Capital expenditure” means, in addition to the definition in s. NR 440.02, an expenditure for a physical or operational change to an existing facility that exceeds P, the product of the facility’s replacement cost, R, and an adjusted annual asset guideline repair allowance, A, as reflected by the following equation:

NR 440.647(2)(a)2.a.a. The adjusted annual asset guideline repair allowance, A, is the product of the percent of the replacement cost, Y, and the applicable basic annual asset guideline repair allowance, B, as reflected by the following equation:
