2) Documentation that the measured value of RSi exceeds zero.
NR 440.71(4)(b)1.b.b. The measurement techniques of subd. 1. a. 1) shall be submitted to the administrator for approval. NR 440.71(4)(b)1.c.c. Each owner or operator demonstrating compliance by the test method described in subd. 1. shall: 1) Measure the amount of coating applied at the coating applicator;
2) Determine the VOC content of all coatings applied using the test method specified in sub. (6) (a);
3) Install, calibrate, maintain and operate, according to the manufacturer’s specifications, a device that indicates the cumulative amount of VOC recovered by the solvent recovery device over each nominal 1-month period. The device shall be certified by the manufacturer to be accurate to within ± 2.0%;
4) Measure the amount of VOC recovered; and
5) Calculate the overall VOC emission reduction (R) for each and every nominal 1-month period using Equation 1.
NR 440.71(4)(b)1.d.d. For facilities subject to sub. (3) (b) or (d), compliance is demonstrated if the value of R is equal to or greater than 93%. NR 440.71(4)(b)1.e.e. Subject to the provisions of subd. 1. f., for facilities subject to sub. (3) (c) 1. to 3., compliance is demonstrated if the value of R is equal to or greater than the percent reduction demonstrated pursuant to par. (a) 1. prior to modification or reconstruction or 93%, whichever is lower. NR 440.71(4)(b)1.f.f. For facilities subject to sub. (3) (c) 3., compliance is demonstrated if the value of E (control device efficiency) is greater than or equal to 0.95 and if the value of R is equal to or greater than the percent reduction demonstrated pursuant to par. (a) 3. or 93%, whichever is lower. NR 440.71(4)(b)2.2. To demonstrate compliance with sub. (3) (b), (c) 1. to 3. or (d), standards for coating operations, when the emissions from only an affected coating operation are controlled by a dedicated incinerator or when a common emission control device, other than a fixed-bed carbon adsorption system with individual exhaust stacks for each adsorber vessel, is used to control emissions from an affected coating operation as well as from other sources of VOC, each owner or operator of an affected coating operation shall perform a gaseous emission test using the following procedures: NR 440.71(4)(b)2.a.a. Construct the overall VOC emission reduction system so that all volumetric flow rates and total VOC emissions can be accurately determined by the applicable test methods and procedures specified in sub. (6) (b) to (g); NR 440.71(4)(b)2.b.b. Determine capture efficiency from the coating operation by capturing, venting and measuring all VOC emissions from the operation. During a performance test, the owner or operator of an affected coating operation located in an area with other sources of VOC shall isolate the coating operation emissions from all other sources of VOC by one of the following methods: 1) Build a temporary enclosure around the affected coating operation; or
NR 440.71 NoteNote: See sub. (2) (a) 16.
2) Shut down all other sources of VOC and continue to exhaust fugitive emissions from the affected coating operation through any building ventilation system and other room exhausts such as drying ovens. All ventilation air shall be vented through stacks suitable for testing;
NR 440.71(4)(b)2.c.c. Operate the emission control device with all emission sources connected and operating; NR 440.71(4)(b)2.d.d. Determine the efficiency (E) of the control device using the following equation: NR 440.71(4)(b)2.e.e. Determine the efficiency (F) of the VOC capture system using the following equation: NR 440.71(4)(b)2.f.f. For each affected coating operation subject to sub. (3) (b) or (d), compliance is demonstrated if the product of (E)× (F) is equal to or greater than 0.93. NR 440.71(4)(b)2.g.g. For each affected coating operation subject to sub. (3) (c) 2., compliance is demonstrated if the product of (E) × (F) is equal to or greater than the fractional reduction demonstrated pursuant to par. (a) 1. prior to modification or reconstruction or 0.93, whichever is lower. NR 440.71(4)(b)2.h.h. For each affected coating operation subject to sub. (3) (c) 3., compliance is demonstrated if the value of E is greater than or equal to 0.95 and if the product of (E) × (F) is equal to or greater than the fractional reduction demonstrated pursuant to par. (a) 3. or 0.93, whichever is lower. NR 440.71(4)(b)3.3. To demonstrate compliance with sub. (3) (b), (c) 1. to 3. or (d), standards for coating operations, when a fixed-bed carbon adsorption system with individual exhaust stacks for each adsorber vessel is used to control emissions from an affected coating operation as well as from other sources of VOC, each owner or operator of an affected coating operation shall perform a gaseous emission test using the following procedures: NR 440.71(4)(b)3.a.a. Construct the overall VOC emission reduction system so that each volumetric flow rate and the total VOC emissions can be accurately determined by the applicable test methods and procedures specified in sub. (6) (b) to (g); NR 440.71(4)(b)3.b.b. Assure that all VOC emissions from the coating operation are segregated from other VOC sources and that the emissions can be captured for measurement, as described in subd. 2. b. 1) and 2);
