Waste exemption: T27 treatment of sheep dip using organophosphate-degrading enzyme

This exemption allows organophosphate sheep dip to be treated with an approved organophosphate degrading enzyme.

Type of activity you can carry out

You can treat organophosphate sheep dip with an approved enzyme at the place where you use the sheep dip.

Type of activity you can’t carry out

You can’t:

  • bring back used and waste sheep dip from other places to be treated on your farm
  • allow others to bring their waste sheep dip to your sheep farm to treat it in your sheep bath

Mobile sheep dippers must not register this exemption if they are transporting waste sheep dip back to their premises to be treated.

Type of waste you can treat

The waste codes are those listed in the List of Wastes (LoW) Regulations. You need to make sure your waste fits within the relevant waste code and description.

Quantity of waste you can treat

You can store or treat up to a maximum of 8,000 litres of sheep dip over a 24-hour period only at the place it was produced.

Key conditions

You must:

  • treat the sheep dip only in accordance with the enzyme manufacturer’s instructions
  • carry out the enzyme treatment in a secure container inside a drain pen or in a secure sheep dip bath
  • carry out the treatment and storage of the sheep dip so that no sheep dip (treated or untreated) can get into drains, watercourses or onto land

Register this exemption

You need to register this exemption with us if you will meet the requirements:

If you want to dispose of the sheep dip that has been treated with an approved enzyme by discharging it to land, you will need to apply for an environmental permit.

Definitions
