February 2025: Business A registers a U11 exemption to spread digestate to land.
May 2025: Business A has spread the digestate at an application rate in the last year of 30 tonnes per hectare. Business A deregisters the exemption.
August2025: Business B registers a U11 exemption at the same site. Business B can use only up to 20 tonnes per hectare for theremainderof the year. This is because Business A has already used part of the maximum per hectare allowance for that site for that year.
