In October 2007, the Environment Agency issued a revised policy statement entitled Our position on composting and potential health effects from bioaerosols. This document clarified the requirement for a site-specific bioaerosol risk assessment if there is a workplace or dwelling within 250 metres of the composting site boundary. A financial impact assessment was not deemed to be appropriate as the document did not alter the original 2001 position.
Small-scale compost sites on farms are currently likely to operate under a registered exemption from an environmental permit.
When registering such sites, the Environment Agency is not required to ask for any information beyond its regulatory remit and therefore does not hold information on whether an exempt site is a farm or not.
The Environment Agency has not made any changes to regulation that would require existing permitted composting sites to relocate.
The Environment Agency has not considered the environmental impact of moving composting sites. Any operators that want to relocate their operations would need to consider the environmental impacts.
