Protection of groundwater against pollution (GAEC 3)

Date published: 1 January, 2015

The aim of these rules is to protect groundwater against pollution.

You must:

1. obtain a licence from the Scottish Environment Protection Agency (SEPA) before disposing of dangerous substances*, such as waste sheep dip* to land

2. comply with the conditions of any licence granted to allow or carry out a disposal of dangerous substances, such as waste sheep dip to land. Some of the conditions relate to:

  • identified disposal sites
  • maximum disposal volume
  • only one disposal per site per year
  • dilution rates
  • keeping disposal records

You must not:

1. cause or permit an activity which is likely to cause pollution of groundwater by an indirect or direct discharge of dangerous substances (eg, an overflowing sheep dipper, a leaking diesel tank, inappropriate disposal of pesticide washings or waste tractor oil)

Disposing of sheep dip to land is covered by the Controlled Activity (CAR) Regulations, for further information contact SEPA or visit their website using the links below.
