How Do I Calculate Organic Waste Credits For a Process Which is Vented to a Control Device?
If you claim credit for waste shipments of material generated from a process that is vented to a control device, two methods are suggested to calculate potential volatile organic waste credits. Method 1: When reporting the material used in a process vented to a control device, apply the control efficiency to the entire amount on Form B3. On Form W, report the amount of recycled material and use an emission factor which incorporates the control efficiency. Calculate this emission factor using the following formula: EF (W) = EF (B3) x (1 – Control Efficiency) where EF (W) = emission factor for column (f) on Form W EF (B3) = emission factor for the corresponding material on Form B3 Then follow the additional instructions for calculating credit. Method 2: If your waste records provide the amount of material that was generated from the process which is vented to the control device but did not go through the control device, enter this amount on Form B3 without applying the control efficiency
