Agricultural Related Prescribed Processes

Pollution from Industry is now regulated and controlled by regulations authorised under the 1990 Environmental Protection Act. This Act goes beyond the minimum requirements laid down by the EC Directive on controlling air pollution from industry (84/360/EEC). The Act covers processes which are considered highly polluting. Schedule B processes which are considered to present a risk to the atmosphere require operating authorisation from the local authority. Schedule A processes are considered to present more of a risk and discharges to all environmental media (air, land and water) are controlled and regulated by the Environment Agency or SEPA. Schedule A Prescribed processes related to agriculture include:-

  • general waste incineration processes under 1 tonne per hour;
  • waste oil burners;
  • straw combustion processes between 0.4 and 3 MW net rated thermal input;
  • wood combustion processes between 0.4 and 3 MW net rated thermal input;
  • poultry litter combustion processes between 0.4 and 3 MW net rated thermal input;
  • animal carcasses incineration under 1 tonne per hour;
  • treatment and processing of animal or vegetable matter including:
    • fur breeding;
    • animal feed compounding;
    • production of compost for mushrooms.

Some processes covered in the Process Guidance Notes, for example, any process under the heading of 'treatment and processing of animal or vegetable matter' are exempt from controls when carried out on a farm and when they do not involve the manufacture of goods for sale. Others may be exempt below certain size of operation, for example animal carcass incineration below 50 Kg/hr.
