Details

These LRWPs include wastewater and water treatment sludges and other process sludges.

If the Environment Agency provides a LRWP for an activity, you can carry it out without an environmental permit for a waste operation provided that you meet all the conditions.

The Environment Agency may review its LRWPs. It may decide the activity is no longer suitable for a LRWP or that the conditions need changing. You must regularly check that the LRWP you are benefiting from is still in place.
