Details

This regulatory position statement (RPS) does not change your legal requirement to get an environmental permit for waste and groundwater activities when you use IBAA in:

• building a road sub-base
• building a construction or structural platform
• pipe bedding

However, the Environment Agency will not normally take enforcement action when you do this without a permit if you comply with the requirements in this RPS.

This enforcement position does not apply to any other legal requirements.
