Upcoming Changes to Bioaerosols Monitoring in 2017
The Environment Agency has published a new Technical Guidance Note (M9) for the Environmental monitoring of bioaerosols at regulated facilities. This note was published in January 2017 and will soon replace the existing 2009 AfOR Standardised Protocol for monitoring ambient bioaerosols at compost facilities.
- The monitoring method for composting sites has been significantly changed:
- Monitoring at the Sensitive Receptor is no longer required
- Instead 3 downwind monitoring locations will be sampled
- The primary downwind location is directly downwind of the composting activity; the other two monitoring locations are to be situated 30° either side of the primary location. This alignment of monitoring locations is referred to as a ‘fan-like shape’;
- All 3 downwind monitoring locations are to be situated the same distance from the centre of the composting activity as the nearest sensitive receptor;
- Monitoring should ideally occur when wind speeds are between 2 – 4 m/s-1;
- There is no longer a requirement to monitor Gram Negative Bacteria;
- The scope for bioaerosols monitoring has now been increased to include open biofilters and anaerobic digestion facilities. New biofilters installations and anaerobic digestion facilities may therefore have to consider budgeting for bioaerosols monitoring as a permit requirement.
The new guidance has only just been published and is not yet active. However, anyone who is affected by bioaerosol monitoring should be aware of the planned changes and be prepared for alterations pertaining to their monitoring requirements.
