Find out about eligibility and requirements for the self supporting covers for slurry stores item.
How much will be paid
£29.50 per square metre.
Where to use this item
Available for Countryside Stewardship Mid Tier, Higher Tier and Capital Grants.
Only:
- in areas targeted for the reduction of water and air pollution from agriculture
- for roofing an existing above ground circular store
- with support from a Catchment Sensitive Farming (CSF) officer
Where this item cannot be used
- for existing square or rectangular slurry or on-farm anaerobic digestate stores
- for floating covers
- to cover any structure other than a slurry or on-farm anaerobic digestate store
- without relevant advice or consents from the Environment Agency (EA) or Local Planning Authority
How this item will benefit the environment
This item will provide a self-supporting cover to an existing circular slurry or on-farm anaerobic digestate store. This will stop rainwater from entering slurry or anaerobic digestate stores and reduce the volume of dirty water that needs to be stored and spread. It will also improve air quality by reducing ammonia emissions.
Requirements
- install a self-supporting cover with a minimum design life of 20 years (with maintenance)
- install a rainproof, self-supporting cover, supported above the slurry or anaerobic digestate store and fastened by tensioners to the side of the tank
- make sure the tank is able to support the cover
- install the cover when the store is empty
- direct the rainwater away from the slurry or anaerobic digestate store into a clean water drain or rainwater harvesting system
- display appropriate signs to warn of the dangers of confined spaces and fragile covers
- meet the requirements of the SSAFO regulations 2010 and Nitrate Vulnerable Zone (NVZ) requirements
- meet relevant British Standards - examine copies of the most up-to-date standards for guidance
Keeping records
Agreement holders will need to keep the following records and supply them on request:
- any consents or permissions connected with the work
- receipted invoices, or bank statements where a receipted invoice is unavailable
- photographs of site before works start
Please see the record keeping and inspection requirements as set out in the relevant Mid Tier, Higher Tier or Capital Grants guidance for more detail. You can find the latest guidance at Countryside Stewardship: get funding to protect and improve the land you manage.
Agreement holders will need to keep the following records and supply them with the claim:
- photographs of the completed work
Before applying, applicants must seek advice from:
- the Environment Agency, to check what is required as new and significantly altered stores may have to meet the silage, slurry and agricultural fuel oil (SSAFO) regulations 2010
- the local planning authority, to check whether planning permission is required to carry out the planned works
You do not need to provide this with your application, but you will need to submit consents/permissions with your payment claim.
Applicants will have to send the following with their application:
- written support from a CSF officer
Advice and suggestions for how to carry out this item
The following section gives advice on carrying out this item successfully but does not form part of the requirements for this item.
How to get more detailed advice
Further design advice is available on how to size the loading and washdown area and holding tanks, and on pesticide washing volume calculations, from CSF.
Consult an engineer before using this item
Before work is carried out, a structural or civil engineer must check that the existing store is able to support a cover. A specialist supplier or tank manufacturer should be consulted.
Biodiversity
This item has been identified as being beneficial for biodiversity. All Countryside Stewardship habitat creation, restoration and management options are of great significance for biodiversity recovery, as are the wide range of arable options in the scheme. Capital items and supplements can support this habitat work depending on the holding’s situation and potential.
The connectivity of habitats is also very important and habitat options should be linked wherever possible. Better connectivity will allow wildlife to move/colonise freely to access water, food, shelter and breeding habitat, and will allow natural communities of both animals and plants to adapt in response to environmental and climate change.
Further information
You can read information about separating clean and dirty water at The Rivers Trust.
Catchment Sensitive Farming (CSF) operates in parts of the country where there are water quality issues linked to farming. The scheme provides farmers with free advice and training. See guidance for further information on CSF support.
