Supporting guidance for Slurry Storage

Date published: 8 January, 2016

This item provides a contribution towards the costs of increasing the slurry storage capacity on your farm. This includes a contribution towards the costs of building the store itself and also the necessary ancillary fittings and assemblies, reception tank and transfer pumps where relevant.

Ensuring that your farm has sufficient slurry storage capacity offers numerous benefits for the environment:

  • having the capacity to store the slurry produced over the housing period will allow the slurry to be spread at the optimal time to meet crop / grass requirements when nutrient uptake will be higher. This reduces the risk of nitrates leaching to surface and ground waters
  • making the best use of the nutrients within the slurry will reduce the requirement for additional bagged fertiliser to be applied thus reducing the farms over all carbon footprint
  • timing applications to meet crop requirements will reduce the loss of nitrates and other pollutants to local watercourses and groundwater, and decrease nitrous oxide emissions (a particularly potent greenhouse gas) from the land to the air
  • sufficient storage will also provide a level of resilience to deal with exceptional weather events such as prolonged wet weather when the risk of slurry run-off or causing damage to the soil are high

Steading Drainage Assessment Plan

Refer to Annex 1 for guidance on the production of a plan.

Farm Waste Management Plan

A Farm Waste Management Plan or similar plan should highlight the volume of slurry produced on the farm and compare this to the current slurry storage capacity. This should identify the additional storage capacity that is required in order to provide six months slurry storage, including identifying any actions that are required to minimise the production of dirty water.

Guidance on the production of a Farm Waste Management Plan can be found in Annex 2.

Once it has been established how much extra slurry storage is required (or if an existing exempt store is to be replaced), thought should be given to the type of slurry storage facility to be created and how it will fit within the current slurry storage facilities.

This item will provide a fixed contribution towards the costs of providing extra storage and this will be at the same rate for all types of above- or below-ground slurry stores.

Irrespective of the type of storage facility to be constructed it is important that it is correctly designed and constructed and that the Scottish Environment Protection Agency is notified at least 28 days prior to bringing the new structure into use:

  • Design standards
    New or substantially enlarged slurry stores must meet the requirements of Schedule 2 of The Control of Pollution (Silage, Slurry and Agricultural Fuel Oil) (Scotland) Regulations 2003 (SSAFO), as amended. The Prevention of Environmental Pollution from Agricultural Activity (PEPFAA) code provides guidance on the SSAFO regulations

  • Scottish Environment Protection Agency approval
    All new or substantially enlarged slurry stores must be approved by the Scottish Environment Protection Agency prior to bringing into use. It is advisable that plans are discussed with the Scottish Environment Protection Agency at an early stage prior to the commencement of works to ensure that the proposed store will comply with the SSAFO regulations.

For information regarding SSAFO, including the 28 day notification form, please contact your local Scottish Environment Protection Agency office.
