Multiply the percent VOC by the pounds of ink purchased to determine the gross VOC emissions from your ink and adhesive use. Determine the amount of hazardous wastes generated during the period from the hazardous waste manifests. Add the beginning and ending hazardous waste inventories to determine the total amount generated. Either through a gas chromatograph or using an assumed average VOC percentage, determine the total VOCs of the hazardous waste generated. Subtract this number from the total gross VOC number to get the net VOC usage.
Any reputable supplier can easily calculate the data.
If you do not want to limit the new press production, take the maximum pounds VOC supplied by your press manufacturer and multiply the number by 8,760 hours available in a year to get the potential VOC emission figure. If the figure is over the allowable minor modification growth limitation accepted by your state, you may have to purchase pollution abatement equipment. You may have to calculate the maximum VOC emissions by one or two shifts per day, five days a week, or whatever limitation you want to use in order to avoid purchasing pollution abatement equipment. Remember, once you commit to restrictions that are approved by EPA, you have to live with them, no matter your production schedule. VOC destruction is only one part of the equation.
