DMIN 3: Extraction, Landfilling and Restoration
The Council will expect any planning application for minerals extraction to include a comprehensive Environmental Impact Assessment (EIA) and adopt an Environmental Management System to outline measures to address environmental impacts and mitigation during all phases of the extraction and restoration process.
Mineral working on the Best and Most Versatile Farmland will only be permitted if working, restoration and aftercare schemes are adopted which enable the land to be restored, as far as it is practicable, to its previous quality or better.
Applicants will be required to show how excavation is to be arranged and to provide for beneficial after use(s) consistent with providing a balanced range of leisure activities and/or creation of natural habitats before any planning permission is granted.
To reduce the environmental impact of aggregates, the Council will make appropriate use of planning conditions dealing with restoration, aftercare and re-use of mineral sites including the use of suitable construction, demolition and excavation waste to restore original ground levels.
