Mineral Consultation Areas

Mineral Consultation Areas
Alternative Title
Mineral Resource Blocks, Rail Aggregate Depots, MCA, MCA2007, Railhead MCAs, Mineral Steralisation MCAs
Dataset Language
Mineral Consultation Areas identified within the Supplementary Planning Document (adopted November 2007), to assist the implementation of the Minerals Local Plan.

The Minerals Consultation Areas (MCAs) consist of mineral sterilisation MCAs and railhead MCAs.

The Mineral Sterilisation MCAs (also know as Minerals Resource Blocks) are areas that have been identified where particular care is needed to prevent the unnecessary sterilisation of sand and gravel resources and to safeguard rail aggregates depots.
The sand and gravel belt and mineral resource blocks outside of this are included for minerals.

The railhead MCAs (also known as Rail Aggregates Depots) are existing operational and/or disused rail aggregates depots (as of March 2007, as identified in the Minerals Local Plan, adopted March 2007 and Minerals Consultation Areas Supplementary Planning Document, adopted November 2007) identified for their protection for the transportation of minerals by rail.

Buffer zones at 250m around the mineral resource blocks and railheads exist to allow consideration of the impact of development close to but outside of the sites.
