40 CFR 60.444 - Performance test procedures.
(b) The performance test for affected facilities controlled by a solvent recovery device shall be conducted as follows:
(c) The performance test for affected facilities controlled by a solvent destruction device shall be conducted as follows:
(2) Determine for each affected facility prior to each test run the weighted average mass of VOC per mass of coating solids applied being used at the facility. The weighted average shall be determined as specified in § 60.443(a). In this application the quantities of Woi, Wsi, and Mci shall be determined for the time period of each test run and not a calendar month as specified in § 60.441.
(4) Determine the percent overall VOC emission reduction of the solvent destruction device by the following equation and procedures:
(i) The owner or operator of the affected facility shall 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 § 60.446(b).
(ii) The owner or operator of an affected facility shall construct a temporary total enclosure around the coating line applicator and flashoff area during the performance test for the purpose of capturing fugitive VOC emissions. If a permanent total enclosure exists in the affected facility prior to the performance test and the Administrator is satisfied that the enclosure is totally capturing fugitive VOC emissions, then no additional total enclosure will be required for the performance test.
