Rationale

This activity will apply to the storage and treatment of less than, or equal to, 500 tonnes of biowaste for composting in an enclosed system at any one time, with a capacity of equal to or less than 75 tonnes per day.

The permitted waste types are limited to those suitable for enclosed composting and the specific types of biowaste that can be stored and treated are specified in the conditions.

To reduce risks associated with any emissions from the composting activity the enclosed composting system must have an emissions abatement system. 

All liquid waste produced onsite must be stored in a sealed system to reduce risks associated with any run-off from the composting activity.

Bioaerosol management will be covered by a specific standard condition. Measures to prevent bioaerosol releases should be in place and documented in the written management system.

28. Do you agree with the list of standard conditions for the Storage and treatment of less than, or equal to, 500 tonnes of biowaste for composting in an enclosed system at any one time, with a capacity of equal to or less than 75 tonnes a day?
