Division 2 Monitoring

| Monitoring frequencies may be adapted if the data series clearly demonstrate a sufficient stability. | |||
| The sampling point is located where the emission leaves the installation. | |||
| TOC monitoring and COD monitoring are alternatives. TOC monitoring is the preferred option because it does not rely on the use of very toxic compounds. | |||
| TN and Ninorg monitoring are alternatives. | |||
| An appropriate combination of these methods can be used. | |||

Where large amounts of VOCs are handled, the screening and quantification of emissions from the installation by periodic campaigns with optical absorption-based techniques, such as Differential absorption light detection and ranging (DIAL) or Solar occultation flux (SOF), is a useful complementary technique to the techniques I to III.
- BAT 3Division BAT 3
- BAT 4Division BAT 4
- BAT 5BAT is to periodically monitor diffuse VOC emissions to air from relevant sources by using an appropriate combination of the techniques I-III or, where large amounts of VOC are handled, all of the techniques I-III.
