Chapter NR 449

NR 449.09(6)(e)1.a. a. If Method 106 is used to determine the concentration of vinyl chloride (Cb), the sample shall be withdrawn at a constant rate with a probe of sufficient length to reach the vessel bottom from the manhole. Samples shall be taken for 5 minutes within 6 inches of the vessel bottom, 5 minutes near the vessel center, and 5 minutes near the vessel top.

NR 449.09(6)(e)1.b. b. If a portable hydrocarbon detector is used to determine the concentration of vinyl chloride (Cb), a probe of sufficient length to reach the vessel bottom from the service access hole shall be used to make the measurements. One measurement shall be made within 6 inches of the vessel bottom, one near the vessel center and one near the vessel top. Measurements shall be made at each location until the reading is stabilized. All hydrocarbons measured shall be assumed to be vinyl chloride.

NR 449.09(6)(e)1.c. c. The production rate of polyvinyl chloride (Z) shall be determined by a method submitted to and approved by the department.

NR 449.09(6)(e)2. 2. A calculation based on the number of evacuations, the vacuum involved, and the volume of gas in the reactor is hereby approved by the department as an alternative method for determining reactor opening loss for past polymerization reactors in the manufacture of bulk resins.

NR 449.10 NR 449.10 Emission monitoring.

NR 449.10(1) (1) A vinyl chloride monitoring system shall be used to monitor on a continuous basis the emissions from the sources for which emission limits are prescribed in ss. NR 449.04 (1) and (2), 449.05 (1) and 449.06 (1) (a), (2) to (4), and for any control system to which vinyl chloride reactor emissions are required to be ducted in s. NR 449.06 (1) (b) or to which fugitive emissions are required to be ducted in s. NR 449.07 (2) (a) 2., (b), (e), (f) 2. and (i) 2.

NR 449.10(2) (2) The vinyl chloride monitoring system used to meet the requirement in sub. (1) shall be a device which obtains air samples from one or more points on a continuous sequential basis and analyzes the samples with gas chromatography or, if the owner or operator assumes that all hydrocarbons measured are vinyl chloride, with infrared spectrophotometry, flame ion detection, or an equivalent or alternative method. The vinyl chloride monitoring system used to meet the requirements in s. NR 449.07 (2) (h) 2. may be used to meet the requirements of this section.

NR 449.10(3) (3) A daily span check shall be conducted for each vinyl chloride monitoring system used. For all of the emission sources listed in sub. (1), except the one for which an emission limit is prescribed in s. NR 449.04 (2), the daily span check shall be conducted with a concentration of vinyl chloride equal to 10 parts per million. For the emissions source for which an emission limit is prescribed in s. NR 449.04 (2), the daily span check shall be conducted with a concentration of vinyl chloride which is determined to be equivalent to the emission limit for that source based on the emission test required by s. NR 449.09. The calibration shall be done with:

NR 449.10(3)(a) (a) A calibration gas mixture prepared from the gases specified in sections 5.2.1 and 5.2.2 and in accordance with section 7.1 of Method 106 of 40 CFR part 61, Appendix B, incorporated by reference in s. NR 484.04 (23), or

NR 449.10(3)(b) (b) A calibration gas cylinder standard containing the appropriate concentration of vinyl chloride. The gas composition of the calibration gas cylinder standard shall have been certified by the manufacturer. The manufacturer must have recommended a maximum shelf life for each cylinder so that the concentration does not change greater than plus or minus 5% from the certified value. The date of gas cylinder preparation, certified vinyl chloride concentration and recommended maximum shelf life must have been affixed to the cylinder before shipment from the manufacturer to the buyer. If a gas chromatograph is used as the vinyl chloride monitoring system, these gas mixtures may be directly used to prepare a chromatograph calibration curve as described in section 7.3 of Method 106 of 40 CFR part 61, Appendix B, incorporated by reference in s. NR 484.04 (23). The requirements in sections 5.2.3.1 and 5.2.3.2 of Method 106 for certification of cylinder standards and for establishment and verification of calibration standards shall be followed.
