This publication was withdrawn on

All pollution prevention guidance (PPGs) that was previously maintained by the Environment Agency has been withdrawn from use and can now be found on The National Archives.

Pollution prevention guidance contained a mix of regulatory requirements and good practice advice. The Environment Agency does not provide ‘good practice’ guidance.

Current guidance explains how to: report an environmental incident, get permission to discharge to surface or groundwater, manage business and commercial waste, store oil and any oil storage regulations, discharge sewage with no mains drainage, work on or near water and manage water on land.

Pollution Prevention Guidance 3 (PPG3) provides information about choosing and using oil interceptors to comply with environmental law and prevent pollution. It gives information to businesses about choosing, installing and maintaining an oil separator.

Oil separators can be fitted to surface water drains to protect the environment. They work by separating oil from water and containing the oil safely.
