NR 440.65(4)(b)3.3. The weighted average VOC content of the inks shall be calculated over a period that does not exceed one calendar month or 4 consecutive weeks. A facility that uses an accounting system based on quarters consisting of two 28 calendar day periods and one 35 calendar day period may use an averaging period of 35 calendar days 4 times per year, provided the use of such an accounting system is documented in the initial performance test. NR 440.65(4)(b)4.4. Each determination of the weighted average VOC content shall constitute a performance test for any period when VOC emission control equipment is not used. Results of the initial performance test shall be reported to the department. Method 24 or ink manufacturers’ formulation data along with plant blending records (if plant blending is done) may be used to determine VOC content. The department may require the use of Method 24 if there is a question concerning the accuracy of the ink manufacturer’s data or plant blending records. NR 440.65(4)(b)5.5. If, during the time periods when emission control equipment is not used, all inks used contain less than 1.0 kilogram VOC per kilogram ink solids the owner or operator is not required to calculate the weighted average VOC content but shall verify and record the VOC content of each ink (including any added dilution solvent) used as determined by Method 24, ink manufacturers’ formulation data or plant blending records. NR 440.65(4)(c)(c) To determine compliance with sub. (3) (a) 1. the owner or operator may determine the weighted average VOC content using an inventory system. NR 440.65(4)(c)1.1. The inventory system shall accurately account to the nearest kilogram for the VOC content of all inks and dilution solvent used, recycled and discarded for each affected facility during the averaging period. Separate records must be kept for each affected facility. NR 440.65(4)(c)2.2. To determine VOC content of inks and dilution solvent used or recycled, Method 24 or ink manufacturers’ formulation data shall be used in combination with plant blending records (if plant blending is done) or inventory records or purchase records for new inks or dilution solvent. NR 440.65(4)(c)3.3. For inks to be discarded only Method 24 shall be used to determine the VOC content. Inks to be discarded may be combined prior to measurement of volume or weight and tested by Method 24. NR 440.65(4)(c)4.4. The department may require the use of Method 24 if there is a question concerning the accuracy of the ink manufacturer’s data or plant records. NR 440.65(4)(c)5.5. The department shall approve the inventory system of accounting for VOC content prior to the initial performance test. NR 440.65(4)(d)(d) To demonstrate compliance with sub. (3) (a) 2. the owner or operator of an affected facility controlled by a solvent recovery emission control device or an incineration control device shall conduct a performance test to determine overall VOC emission control efficiency according to the following procedures: NR 440.65(4)(d)1.1. The performance test shall consist of 3 runs. Each test run must last a minimum of 30 minutes and shall continue until the printing operation is interrupted or until 180 minutes of continuous operation occurs. During each test run the print line shall be printing continuously and operating normally. The VOC emission reduction efficiency achieved from each test run is averaged over the entire test run period. NR 440.65(4)(d)2.2. VOC concentration values at each site shall be measured simultaneously. NR 440.65(4)(d)3.3. The volumetric flow rate shall be determined from one Method 2 measurement for each test run conducted immediately prior to, during, or after that test run. Volumetric flow rates at each site do not need to be measured simultaneously. NR 440.65(4)(d)4.4. In order to determine capture efficiency from an affected facility all fugitive VOC emissions from the affected facility shall be captured and vented through stacks suitable for measurement. During a performance test the owner or operator of an affected facility located in an area with other sources of VOC shall isolate the affected facility from other sources of VOC. These requirements shall be accomplished using one of the following methods: NR 440.65(4)(d)4.b.b. Build a temporary enclosure around the affected facility and duplicate, to an extent that is reasonably feasible, the ventilation conditions that are in effect when the affected facility is not enclosed (one way to do this is to divide the room exhaust rate by the volume of the room and then duplicate that quotient or 20 air changes per hour, whichever is smaller, in the temporary enclosure); or NR 440.65(4)(d)4.c.c. Shut down all other sources of VOC and continue to exhaust fugitive emissions from the affected facility through any building ventilation system and other room exhausts such as print line ovens and embossers. NR 440.65(4)(d)5.5. For each affected facility compliance with sub. (3) (a) 2. has been demonstrated if the average value of the overall control efficiency (EF) for the 3 runs is equal to or greater than 85%.
