NR 440.686NR 440.686Volatile organic compound (VOC) emissions from synthetic organic chemical manufacturing industry (SOCMI) distillation operations.
NR 440.686(1)(1)Applicability and designation of affected facility.
NR 440.686(1)(a)(a) The provisions of this section apply to each affected facility designated in par. (b) that is part of a process unit that produces any of the chemicals listed in sub. (8) as a product, co-product, by-product or intermediate, except as provided in par. (c).
NR 440.686(1)(b)(b) The affected facility is any of the following for which construction, modification or reconstruction commenced after December 30, 1983:
NR 440.686(1)(b)1.1. Each distillation unit not discharging its vent stream into a recovery system.
NR 440.686(1)(b)2.2. Each combination of a distillation unit and the common recovery system into which its vent stream is discharged.
NR 440.686(1)(b)3.3. Each combination of 2 or more distillation units and the common recovery system into which their vent streams are discharged.
NR 440.686(1)(c)(c) Exemptions from the provisions of par. (a) are as follows:
NR 440.686(1)(c)1.1. Any distillation unit operating a part of a process unit which produces coal tar or beverage alcohols or which uses, contains and produces no VOC is not an affected facility.
NR 440.686(1)(c)2.2. Any distillation unit that is subject to the provisions of s. NR 440.647 is not an affected facility.
NR 440.686(1)(c)3.3. Any distillation unit that is designed and operates as a batch operation is not an affected facility.
NR 440.686(1)(c)4.4. Each affected facility that has a total resource effectiveness (TRE) index value greater than 8.0 is exempt from all provisions of this section except for subs. (3), (5) (d), (e) and (f) and (6) (h) and (L).
NR 440.686(1)(c)5.5. Each affected facility in a process unit with a total design capacity for all chemicals produced within that unit of less than one gigagram per year is exempt from all provisions of this section except for the recordkeeping and reporting requirements in sub. (6) (j), (L) 6. and (n).
NR 440.686(1)(c)6.6. Each affected facility operated with a vent stream flow rate less than 0.008 scm/min is exempt from all provisions of this section except for the test method and procedure and the recordkeeping and reporting requirements in subs. (5) (g) and (6) (i), (L) 5. and (o).
NR 440.686 NoteNote: The intent of these standards is to minimize the emissions of VOC through the application of best demonstrated technology (BDT). The numerical emission limits in these standards are expressed in terms of total organic compounds (TOC), measured as TOC less methane and ethane. This emission limit reflects the performance of BDT.
NR 440.686(1)(d)(d)
NR 440.686(1)(d)1.1. Owners or operators of process vents that are subject to this section may choose to comply with the provisions of 40 CFR part 65, subpart D, as in effect on December 14, 2000, to satisfy the requirements of subs. (3) to (6). The provisions of 40 CFR part 65, subpart D, as in effect on December 14, 2000, also satisfy the criteria of par. (c) 4. and 6. Other provisions applying to an owner or operator who chooses to comply with 40 CFR part 65, subpart D, as in effect on December 14, 2000, are provided in 40 CFR 65.1.
NR 440.686(1)(d)2.2. Owners or operators who choose to comply with 40 CFR part 65, subpart D, 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 D, as in effect on December 14, 2000, 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 D, as in effect on December 14, 2000, shall comply with 40 CFR part 65, subpart A.
NR 440.686(1)(d)3.3. Owners or operators who choose to comply with 40 CFR part 65, subpart D, as in effect on December 14, 2000, at initial startup shall comply with subds. 1. and 2. for each vent stream on and after the date on which the initial performance test is completed, but not later than 60 days after achieving the maximum production rate at which the affected facility will be operated, or 180 days after the initial startup, whichever date comes first.
NR 440.686(1)(d)4.4. Each owner or operator subject to the provisions of this section that chooses to comply with 40 CFR part 65, subpart D, as in effect on December 14, 2000, at initial startup shall notify the administrator of the specific provisions of 40 CFR 65.63 (a) (1), (2) or (3), 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 440.686(2)(2)Definitions. As used in this section, all terms not defined here shall have the meaning given them in s. NR 440.02 and the following terms shall have the specific meanings given them:
NR 440.686(2)(a)(a) “Batch distillation operation” means a noncontinuous distillation operation in which a discrete quantity or batch of liquid feed is charged into a distillation unit and distilled at one time. After the initial charging of the liquid feed, no additional liquid is added during the distillation operation.
NR 440.686(2)(b)(b) “Boiler” means any enclosed combustion device that extracts useful energy in the form of steam.
NR 440.686(2)(c)(c) “By compound” means by individual steam components, not carbon equivalents.
NR 440.686(2)(d)(d) “Continuous recorder” means a data recording device recording an instantaneous data value at least once every 15 minutes.
NR 440.686(2)(e)(e) “Distillation operation” means an operation separating one or more feed streams into 2 or more exit streams, each exit stream having component concentrations different from those in the feed streams. The separation is achieved by the redistribution of the components between the liquid and vapor- phase as they approach equilibrium within the distillation unit.
