NR 440.644(4)(j) (j) Rather than seeking to demonstrate compliance with the provisions of sub. (3) (a) 1. a., 2. a., 6. a., 7. b. or 9. a. using the performance test procedures described under pars. (g) and (i), an owner or operator of an undertread cementing operation, sidewall cementing operation, green tire spraying operation where organic solvent-based sprays are used, or Michelin-B operation that use a VOC emission reduction system, may seek to demonstrate compliance by meeting the equipment design and performance specifications listed under subds. 1., 2., and 4. to 6. or under subds. 1. and 3. to 6. and by conducting a control device efficiency performance test to determine compliance as describe under subd. 7. The owner or operator shall conduct this performance test of the control device efficiency no later than 180 days after initial startup of the affected facility, as specified under s. NR 440.08 (1). Meeting the capture system design and performance specifications, in conjunction with operating a 95% efficient control device, is an acceptable means of demonstrating compliance with the standard. Therefore, the requirement for the initial performance test on the enclosure, as specified under s. NR 440.08 (1), is waived. No monthly performance tests are required.

NR 440.644(4)(j)1. 1. For each undertread cementing operation, each sidewall cementing operation, and each Michelin-B operation, the cement application and drying area shall be contained in an enclosure that meets the criteria specified under subds. 2., 4. and 5. For each green tire spraying operation where organic solvent-based sprays are used, the spray application and drying area shall be contained in an enclosure that meets the criteria specified under subds. 3., 4. and 5.

NR 440.644(4)(j)2. 2. The drying area shall be enclosed between the application area and the water bath or to the extent necessary to contain all tire components for at least 30 seconds after cement application, whichever distance is less.

NR 440.644(4)(j)3. 3. Sprayed green tires shall remain in the enclosure for a minimum of 30 seconds after spray application.

NR 440.644(4)(j)4. 4. A minimum face velocity of 30.5 meters (100 feet) per minute shall be maintained continuously through each permanent opening into the enclosure when all temporary enclosure openings are closed. The cross-sectional area of each permanent opening shall be divided into at least 12 equal areas, and a velocity measurement shall be performed at the centroid of each equal area with an anemometer or similar velocity monitoring device; the face velocity of each permanent opening is the average value of the velocity measurements taken. The monitoring device shall be calibrated and operated according to the manufacturer’s instructions. Temporary enclosure openings shall remain closed at all time except when worker access is necessary.

NR 440.644(4)(j)5. 5. The total area of all permanent openings into the enclosure may not exceed the area that would be necessary to maintain the VOC concentration of the exhaust gas stream at 25% of the lower explosive limit (LEL) under the following conditions:

NR 440.644(4)(j)5.a. a. The facility is operating at the maximum solvent use rate;

NR 440.644(4)(j)5.b. b. The face velocity through each permanent opening is 30.5 meters (100 feet) per minute.

NR 440.644(4)(j)5.c. c. All temporary openings are closed.

NR 440.644(4)(j)6. 6. All captured VOC are ducted to a VOC emission control device that is operated on a continuous basis and that achieves at least a 95% destruction or recovery efficiency.

NR 440.644(4)(j)7. 7. The efficiency of the control device (E) for the initial performance test shall be determined by using values of the volumetric flow rate of each of the gas streams and the VOC content (as carbon) of each of the gas streams in and out of the control device as described under par. (f) 2. b. The control device efficiency shall be redetermined during conditions specified under par. (b) 3.

(3) (a) 1. b., 2. b., 6. b., 7. b., 8. b., 9. b. or 10. b. shall demonstrate, using the procedures described under par. (c), that the total VOC use at the affected facility has not exceeded the applicable total (uncontrolled) monthly VOC use limit during each of the last 6 months of operation.

(4) (f) 2. d. 7) and 8). The owner or operator shall notify the department at least 30 days in advance of any test by either Method 25 or Method 25A. Method 1 shall be used to select the sampling site and the sampling point shall be the centroid of the duct or at a point no closer to the walls than 1 one meter (3.3 feet). Method 2, 2A, 2C or 2D, as appropriate, shall be used as the test method for the concurrent determination of gas flow rate in the capture system.

Instrument calibration shall be performed by the procedure given in Method 25A using the single VOC present in the capture system.

After the instrument has been calibrated, determine the background VOC concentration of the air drawn into the capture system immediately upwind of the application area for each run. The instrument does not need to recalibrated for the background measurement. Subtract this reading from the reading obtained in the capture system for that run. The Method 25A results shall only be used in the alternative procedure for determination of capture efficiency described under sub. (4) (f) 2. d. 7).
