The General Binding Rules
The General Binding Rules for small sewage discharges from Small Septic Tanks and Sewage Treatment Plants is a set of rules-based regulation intended to “simplify” the regulation of small sewage discharges. Essentially the intention is that if you meet the rules you can make a discharge without an environmental permit.
How it affects you.
The general binding rules are legally mandated requirements within environmental regulations, setting minimum standards for activities like small sewage discharges. They ensure that activities are conducted safely and do not cause pollution.
In the UK, these rules specifically govern the operation of septic tanks and small sewage treatment plants, focusing on proper maintenance and preventing environmental harm.
