All emissions of DMF are from the multi -stage horizontal spray water scrubber (BCD -DI) that has a documented DMF control efficiency of 97%. DMF Before -Control Emissions: The before -control DMF emission rate is determined by the hours that each of the various tinted bandwidths are produced during the year. The hours of production for a specific bandwidth is then multiplied by the DMF emission factor for that bandwidth to determine the before-contol quantity of DMF that would have been emitted from the tinting process. The emitted DMF quantities for each bandwidth is then summed to obtain the total before -control DMF emission quantity. That determination is shown in the preceeding ButaciteO Tinting Process DMF Emissions Report. For 2008, the before -control DMF emission to the scrubber was 14331 lbs. DMF After -Control Emissions: Before -control DMF emissions = 14,331.8 pounds DMF control efficiency of the Tinting water scrubber (BCD -DI) = 97% After -control emissions utilizing the 97% control efficient water scrubber (BCD -DI): After -control DMF emissions would be: 100% — 97% = 3 % of the incoming DMF Therefore, after -control emissions = 14,331.8 pounds X 3% 430.0 pounds DMF DEQ-CFW 00086023
