General binding rules is a term given to legally binding requirements in regulations that set the minimum standards or conditions which apply. In this case the conditions are set in the Environmental Permitting (England and Wales) (Amendment) (England) Regulations 2014.
The general binding rules consist of the conditions together with technical requirements specified by the Environment Agency in guidance to operators. Compliance with these requirements is part of the conditions. These will apply to anyone who has a septic tank or sewage treatment plant that makes a small sewage discharge, from January 2015. The general binding rules set out the conditions that septic tanks and sewage treatment plants need to meet in order to be used without an environmental permit.
