NR 440.644(3)(b) (b) Alternate standard. On and after the date on which the initial performance test, required by s. NR 440.08, is completed, but no later than 180 days after September 19, 1989, no owner or operator subject to the provisions in sub. (1) (b) may cause to be discharged into the atmosphere more than 25 grams (0.055 lb) of VOC per tire processed for each month if the operation uses 25 grams (0.055 lb) or less of VOC per tire processed and does not employ a VOC emission reduction system.

NR 440.644(4) (4) Performance test and compliance provisions.

NR 440.644(4)(a) (a) Section NR 440.08 (4) does not apply to the monthly performance test procedures required by this section. Section NR 440.08 (4) does apply to initial performance tests and to the performance tests specified under par. (b) 2. and 3. Section NR 440.08 (6) does not apply when Method 24 of Appendix A, 40 CFR part 60, incorporated by reference in s. NR 440.17, is used.

NR 440.644(4)(b) (b) Performance tests shall be conducted as follows:

NR 440.644(4)(b)1. 1. The owner or operator of an affected facility shall conduct an initial performance test, as required under s. NR 440.08 (1), except as described under par. (j). The owner or operator of an affected facility shall thereafter conduct a performance test each month except as described under subd. 4. and pars. (g) and (j). Initial and monthly performance tests shall be conducted according to the procedures in this subsection.

NR 440.644(4)(b)2. 2. The owner or operator of an affected facility who elects to use a VOC emission reduction system with a control device that destroys VOC (e.g., incinerator), as described under pars. (f) and (g), shall repeat the performance test when directed by the department or when the owner or operator elects to operate the capture system or control device at conditions different from the most recent determination of overall reduction efficiency. The performance test shall be conducted in accordance with the procedures described under par. (f) 2. a. to d.
