Derby & Derbyshire Minerals Core Strategy: Key Issues & Options

Objective G: Reducing the landbank of permitted reserves of crushed rock in Derbyshire?

7.83 Government policy in MPS1 sets out the requirement to reduce the size of landbanks where they are judged to be excessive.  It requires MPAs to maintain a landbank of crushed rock to last for 10 years. 

7.84 There are over 800 million tonnes of hard rock reserves (for aggregate use) in Derbyshire, the vast majority being limestone.  This is sufficient to enable production to continue for over 95 years.  As a result, we are obliged to consider taking steps to reduce this excessive landbank of aggregate crushed rock.  Additional sites will not be required to meet the general demand for aggregate crushed rock during the lifetime of this Core Strategy.

7.85 The issue regarding aggregate crushed rock, therefore, will be how should we try to reduce the amount of permitted reserves in Derbyshire.  By simply not allowing any new permissions, it no meaningful reduction in the size of the landbank is likely to be achieved.  However, it may be possible to grant some new permissions in order to reach agreement with operators to relinquish larger reserves elsewhere.  One option is that this could include the relinquishment of reserves in the Peak District National Park.  This might only happen if there were clear benefits to be obtained from doing so, for example, the existing operation may be more environmentally or socially sensitive than the new proposed site. 

7.86 We think that, in order to have an impact on the huge landbank of permitted reserves of crushed rock in Derbyshire, operators should relinquish a substantially larger proportion of reserves than is permitted as part of a new permission, for example, 2-3 times more reserves could be given up than is granted permission.  This may vary from case to case depending on the particular circumstances involved.  If the relinquished permissions are within the Peak National Park, this would have the additional benefit of helping to achieve the wider strategic objective of reducing the amount of aggregate producted from within the Park.

7.87 For these reasons, we think that some new permissions may be necessary to achieve some reduction in the overall landbank of aggregate crushed rock.  An example of how we think this could be achieved is as follows:

7.88 We think there may be potential for further exploration of aggregate quality crushed rock in the Permian Limestone resource in the east of the county.  There is one quarry quarrying the aggregate grade limestone in this area.  This is Bolsover Moor Quarry.  This quarry is situated on higher ground to the east of Bolsover and has potential to be extended and could replace larger reserves elsewhere in the county. 

7.89 Relatively low grade material is extracted from this quarry, mainly for use as roadstone.  Depending on the particular markets to be supplied, it could replace the use of a proportion of the higher grade Carboniferous Limestone, which may be quarried for this purpose from the west of the county in the Matlock/Wirksworth or Buxton areas, and may, therefore, represent a more efficient and sustainable use of Derbyshire's mineral resources.  The topography of the landscape around the Bolsover Moor Quarry means that an extension might be worked in a less intrusive way than quarries in the western part of the county.  Increased and continued production here in favour of quarries in the west of Derbyshire could also bring the benefit of reducing cross county lorry movements from quarries in the west to markets in the east of the region and beyond.

7.90 The operator of this quarry would have to give up a greater amount of aggregate crushed rock reserves elsewhere in the county in exchange for an extension at Bolsover Moor Quarry.

Issue 17: Reducing the Landbank of Crushed Rock in Derbyshire (a)

What would be the best way of reducing the landbank for crushed rock in Derbyshire?

Option Results Count
Option 1: Grant limited new permissions for aggregate crushed rock if operators agree to relinquish reserves of a greater amount in Derbyshire as a condition of the permission.
Option 2: Grant limited new permissions for aggregate crushed rock if operators agree to relinquish reserves of a greater amount in Derbyshire or the Peak District National Park as a condition of the permission

Please explain why you came to that decision. If you chose 'a different option', please explain what that would be.
