Before you start

You’ll need to:

  • use the MAGIC map tool to find the 10 digit National Grid reference of the proposed store
  • know the address of the store
  • provide your contact details
  • confirm the store is not within 10 metres of coastal waters or inland freshwaters
  • confirm the store is not within 50 metres of a spring, well or bore-hole

Additional information about your proposed storage

You can choose to provide additional information to the Environment Agency such as:

  • site plans
  • design drawings for your proposed storage
  • a copy of the manufacturer’s specifications and guarantee if you plan to use prefabricated products
  • soil tests if you’re constructing an earth-bank slurry store

If you provide the additional information, we can give you bespoke guidance and recommendations to make sure you build the right store in the right place.
