MIN3 Restriction on Area of Land South of the M4 Motorway Subject to Planning Consent for Sand and Gravel Extraction and/or Waste Disposal

The minerals planning authority will not normally grant permissions that would result in more than 165 hectares of land south of the M4 motorway being subject to planning consent for sand and gravel extraction and/or waste disposal and where the full restoration is yet to be completed, except in exceptional circumstances. such circumstances may include:

  1. The need to supply an adjacent or nearby major project;
  2. Where the production of sand and gravel is an incidental by-product of development for some other primary purpose;
  3. When refusal of permission based solely on this policy would sterilise the orderly working of reserves that could be processed through an existing environmentally acceptable processing plant;
  4. Short-term working when the output from a newly commissioned quarry may overlap with the production from one nearing closure through exhaustion of its available reserves.
  5. Where other long term environmental objectives of the council could be secured by working the land for sand and gravel.
