Initial Consultation document

Question 1: 'Minerals and Waste Local Plan Vision'
The Vision should refer the provision of minerals supply to be in accordance with and as required by National Policy
Mineral Safeguarding should refer to paragraph 182 of the revised National Planning Policy Framework such that the applicant for adjacent development ('agent of change') should be required to provide suitable mitigation to take account of existing and allocated development.

Question 3: 'Minerals Strategic Objectives'
The following amendments are proposed (in CAPITALS):
MSO2. To provide a steady and adequate supply of industrial minerals by identifying adequate mineral extraction sites/areas within Norfolk sufficient to meet the forecast need AND STOCKS OF PERMITTED RESERVES OF SILICA SAND OF AT LEAST 10 YEARS PRODUCTION FOR INDIVIDUAL SILICA SITES AND AT LEAST 15 YEARS FOR SILICA SAND SITES WHERE SIGNIFICANT NEW CAPITAL IS REQUIRED and safeguarding existing infrastructure. (To accord with NPPF 2018 paragraph 208 footnote 68)

MSO4. To safeguard silica sand, carstone, and sand and gravel resources for future use. Avoiding unnecessary sterilisation by encouraging the extraction of minerals prior to other development taking place where practicable and using minerals in construction on the land from which they are extracted. THE 'AGENT OF CHANGE' PRINCIPLE WILL BE APPLIED TO ANY NEW PROPOSED DEVELOPMENT IMPACTING ON SAFEGUARDED AREAS OR SITES.

MSO5. To promote the sustainable transport of minerals by rail, road and water, including the safeguarding of railheads and wharfs for the import of minerals to and export of minerals from Norfolk. THE 'AGENT OF CHANGE' PRINCIPLE WILL BE APPLIED TO ANY NEW PROPOSED DEVELOPMENT IMPACTING ON SAFEGUARDED SITES.

MSO8. To ensure that mineral development addresses and minimises the impacts it will have on climate change by: REDUCING greenhouse gas emissions during the winning, working and handling of minerals, SEEK TO PROVIDE sustainable patterns of minerals transportation, and WHERE POSSIBLE integrating features consistent with climate change mitigation and adaption into the design of restoration and aftercare proposals.
MSO9. To positively contribute to the natural, built and historic environments with high quality, progressive and expedient restoration to achieve a beneficial after use. The after use will protect and enhance the environment, including landscape and biodiversity improvements.

Comment: the restoration of mineral sites can deliver landforms to facilitate different after uses of land, however mineral planning has no role in the after use of itself.

MSO10. WHERE PRACTICAL to increase public access to the countryside and enhance biodiversity through enhancing the amenity value of land when restoring extraction sites.

Question 4: Policy MW1 'Presumption in favour of sustainable development'
This policy is supported including the recognition in the preamble that the three pillars of sustainability have equal standing.
 
Question 5: Policy MW2 'Development Management Criteria'
Where appropriate AND PRACTICAL, enhancement of the environment would be sought, including, but not exclusively, the enhancement of the Public Rights of Way Network, creation of recreation opportunities and enhancement of the natural, historic and built environment and surrounding landscapes.

Question 6: Policy MW3 'transport'

d) WHERE PRACTICAL AND RELEVANT to demonstrate the use of sustainable drainage systems, water harvesting from impermeable surfaces and layouts that accommodate waste water recycling
e) WHERE RELEVANT TO take account of potential changes in climate including rising sea levels and coastal erosion
g) incorporate proposals for sustainable travel, including travel plans where PRACTICAL AND appropriate.

Question 9: Policy MW6 'agricultural soils'
This policy should be applied flexibly since minerals can clearly only be worked where they exist and for silica sand for glass making the potential land is further restricted by virtue of the scarcity of this mineral.

Question 27: Policy MP1 'Provision for minerals extraction'
No as it does not accord with National Policy and is unsound. Suggested wording for silica sand:
STOCKS OF PERMITTED RESERVES for silica sand will be maintained at 10 years' PRODUCTION FOR EACH SILICA SAND SITE. Sufficient sites and/or areas to deliver at least 12,380,000 tonnes of silica sand will be allocated TO THE END OF THE PLAN PERIOD WITH FURTHER PROVISION TO ENSURE A STOCK OF PERMITTED RESERVES BEYOND THE PLAN PERIOD.
In the table on page 63 in the preamble to Policy MP1 is should read:
B Silica sand permitted reserve at 31/12/2016

Question 28: Policy MP2 'Spatial strategy for minerals extraction'
"Within the resource areas identified on the key diagram, specific sites or preferred areas for silica sand extraction should be located where they are able to access the existing processing plant and railhead at Leziate via conveyor, pipeline or off-public highway routes". This contradicts wording in proposed Policy MP13 and the Single Issue Silica Sand Review of the Minerals Site Specific Allocations DPD (adopted in December 2017) which discussed highway routes from Areas of Search to the Leziate processing site.
There should be no buffers applied to the so-called planning constraints. The acceptability or not of approaching such constraints will be a matter for the EIA.
Agricultural land grades 1 and 2 should not be excluded. This contradicts Policy MW6 which should in all circumstances be adopted and applied flexibly.

Question 33: Policy MP7 'Progressive working, restoration and after-use'
After use is noted several times in the policy but after use is not a matter for mineral planning.
There is no mention of restoration to agricultural land
Any important geology or geomorphology on the site will be retained in sample exposures for study purposes ONLY WHERE PRACTICAL AND SAFE TO DO SO

Question 36: Policy MP10 'Safeguarding of port and rail facilities, and facilities for the manufacture of concrete, asphalt and recycled materials'
The 'agent of change' principle will be applied to all development in proximity to safeguarded sites.


Question 37: Policy M11 'Mineral Safeguarding Areas and Mineral Consultation Areas'
The 'agent of change' principle will be applied to all development in proximity to safeguarded sites.

Question 67: Proposed Site MIN 40 'land east of Grandcourt Farm, East Winch'
The site is allocated as a specific site for silica sand extraction in the Adopted in the Core Strategy and Minerals and Waste Development Management Policies Development Plan Document 2010-2026 (adopted September 2011) and identified in the Minerals Site Specific Allocations Development Plan Document (DPD) (adopted October 2013, amendments adopted December 2017).

The Initial conclusion on the MIN40 site in the May 2018 consultation document notes that "the site is considered suitable for allocation for silica sand extraction, subject to any planning application addressing the requirements below: [requirements are detailed in the Initial Consultation document]

Sibelco has submitted a planning application for an extension of Grandcourt Quarry into the MIN40 site and has the following comments on some of the "requirements" noted in the Initial Consultation document.

* Opportunities during working for any geodiversity assets to be studied, and if compatible with the landscape and ecology objectives, an open face to be retained as part of the restoration scheme

Sibelco will examine working faces during operation and can take photographic records of any features of note observed, if any. Following extraction being completed in each phase, Carstone material will be used to cover and stabilise the Leziate Sand faces to create safe long term slopes as described in Appendix 9 to the submitted Planning Statement (Geotechnical Design and Assessment).
Opportunities could be afforded during working to geology students to inspect and study open faces and overburden areas under supervision where consistent with health and safety of the site. Bearing in mind the proposed open water restoration with peripheral broadleaved woodland and shrub/grassland it is not been possible to incorporate any open face in the restoration, which would in addition be difficult to maintain safely due to the nature of the geology, which makes it vulnerable to erosion and a potential safety hazard.

* A restoration scheme incorporating heathland or a heathland/arable mix with blocks of woodland which provides biodiversity gains and does not result in permanent dewatering of a perched water table in the carstone aquifer if one is identified in a hydrogeological risk assessment
*
The lodged planning application proposes a combination of restored areas of open water (51.4%), native broadleaved woodland (8.8%), hedgerows (increase of 920 linear metres), scrub & species rich grassland (20.7%), agricultural land (15.2%) and public rights of way for the restored site with biodiversity gains. The hydrogeological assessment of the site showed there were no significant impacts on the perched water table in the Carstone as a result of working and restoration.

The proposed restoration is primarily to water since the excavation will be several metres below the natural groundwater level in order to release the proven mineral. It will not be possible to deliver a dry restoration using on-site overburden materials. For the same reason it will not be possible to deliver a requirement of MIN40, which is to incorporate heathland into the restoration. The proposed site for the former Site Specific Allocations DPD was considerably reduced in area at examination which removed land which may have been suitable for heathland restoration. The much reduced currently allocated area reflects very closely the area of excavation. Once the restored margin areas are accounted for, the remaining area of land restoration is at the lake margins on mostly slopes to the water's edge, which is not suitable for heathland. Significant heathland restoration has been delivered by the Applicant on former mineral sites to the north of Middleton Stop Drain.

The proposed restoration scheme is shown on the submitted restoration drawings. This scheme has been designed with due regard for the precise setting of the site; the local geology; local topography; position of the natural groundwater table and the volumes of different overburden materials identified within the site by drilling programmes.

Policy Min 40 states that a restoration scheme for the site should seek to incorporate heathland or a heathland/arable mix with blocks of woodland which provides biodiversity gains. Given the volumes of sand and overburden materials present and the position of the local groundwater table this is not possible in its entirety in this case.

Sibelco has restored former mineral extraction area locally to heathland (for example Wicken North and Wicken South), however, these areas have very different physical parameters which allowed such restoration to be designed and implemented. Wicken North and Wicken South are located on lower ground and had relatively low sand to overburden ratios which allowed significant areas to be restored to generally level ground above the local groundwater level. Grandcourt Quarry extension is located on higher ground, has a different ratio of sand to overburden (higher ratio) and a different relationship of ground levels to groundwater level. Final restored slopes must be stable in the long term and at the same time utilise only suitable overburden materials from the site (there are no proposals to import any materials from elsewhere to effect the restoration). Tailings materials from the mineral washing (silts and lays) are unsuitable for restoration in this area due to high water content of the tailings and distance from the processing plant. The company has sufficient permitted tailings space elsewhere on the wider site.

The restoration scheme proposed for the extension area in the lodged planning application does include agricultural land, woodland blocks and scrub with a lake of some 9.2 hectares representing the natural groundwater level. The proposed restoration of the MIN40 site reflects the permitted restoration of the existing Grandcourt Quarry site and has been designed to complement and fit in with this overall restoration which is dictated by the geotechnical assessment and local geological circumstances.

The overburden volumes in the Grandcourt extension area and volumes required to restore the site as per the submitted proposed restoration scheme are as follows:

Overburden materials identified by drilling programmes:
Soils 78,000m3
Carstone 1,300,000 m3
Clay 420,000 m3
Material required to create the proposed landform in the MIN40 site:
Material required to create 1:4 slopes on final sand and overburden faces 1,020,000 m3
Material required to create embankment for bridleway and farm access 736,000 m3
Given the material balance for the site as shown above and with no proposal to import any material for restoration or other purposes, the final landform and restoration scheme proposed is the only one which can reasonably be implemented. The MIN40 site is not suitable for heathland restoration.

The submitted Environmental Statement contains a hydrogeological risk assessment which identifies potential impacts on groundwater including the perched water table in the Carstone. The proposed eastern extension will have little or no additional significant impacts to the north, south and west. The area over which drawdown in groundwater levels will occur will increase to the east, but no water sensitive receptors have been identified within the predicted area of influence in this direction. It is proposed that the potential additional impacts to surface and groundwater are monitored and controlled via a minor revision of the existing Water Management Plan.
There is electricity infrastructure within MIN40 site

Following extraction being completed in each phase, Carstone material will be used to cover and stabilise the Leziate Sand faces to create safe long term slopes as described in Appendix 9 to the submitted Planning Statement (Geotechnical Design and Assessment).
Opportunities could be afforded during working to geology students to inspect and study open faces and overburden areas under supervision where consistent with health and safety of the site. Bearing in mind the proposed open water restoration with peripheral broadleaved woodland and shrub/grassland it is not been possible to incorporate any open face in the restoration, which would in addition be difficult to maintain safely due to the nature of the geology, which makes it vulnerable to erosion and a potential safety hazard.

* A restoration scheme incorporating heathland or a heathland/arable mix with blocks of woodland which provides biodiversity gains and does not result in permanent dewatering of a perched water table in the carstone aquifer if one is identified in a hydrogeological risk assessment
*
The lodged planning application proposes a combination of restored areas of open water (51.4%), native broadleaved woodland (8.8%), hedgerows (increase of 920 linear metres), scrub & species rich grassland (20.7%), agricultural land (15.2%) and public rights of way for the restored site with biodiversity gains. The hydrogeological assessment of the site showed there were no significant impacts on the perched water table in the Carstone as a result of working and restoration.

The proposed restoration is primarily to water since the excavation will be several metres below the natural groundwater level in order to release the proven mineral. It will not be possible to deliver a dry restoration using on-site overburden materials. For the same reason it will not be possible to deliver a requirement of MIN40, which is to incorporate heathland into the restoration. The proposed site for the former Site Specific Allocations DPD was considerably reduced in area at examination which removed land which may have been suitable for heathland restoration. The much reduced currently allocated area reflects very closely the area of excavation. Once the restored margin areas are accounted for, the remaining area of land restoration is at the lake margins on mostly slopes to the water's edge, which is not suitable for heathland. Significant heathland restoration has been delivered by the Applicant on former mineral sites to the north of Middleton Stop Drain.

The proposed restoration scheme is shown on the submitted restoration drawings. This scheme has been designed with due regard for the precise setting of the site; the local geology; local topography; position of the natural groundwater table and the volumes of different overburden materials identified within the site by drilling programmes.

Policy Min 40 states that a restoration scheme for the site should seek to incorporate heathland or a heathland/arable mix with blocks of woodland which provides biodiversity gains. Given the volumes of sand and overburden materials present and the position of the local groundwater table this is not possible in its entirety in this case.

Sibelco has restored former mineral extraction area locally to heathland (for example Wicken North and Wicken South), however, these areas have very different physical parameters which allowed such restoration to be designed and implemented. Wicken North and Wicken South are located on lower ground and had relatively low sand to overburden ratios which allowed significant areas to be restored to generally level ground above the local groundwater level. Grandcourt Quarry extension is located on higher ground, has a different ratio of sand to overburden (higher ratio) and a different relationship of ground levels to groundwater level. Final restored slopes must be stable in the long term and at the same time utilise only suitable overburden materials from the site (there are no proposals to import any materials from elsewhere to effect the restoration). Tailings materials from the mineral washing (silts and lays) are unsuitable for restoration in this area due to high water content of the tailings and distance from the processing plant. The company has sufficient permitted tailings space elsewhere on the wider site.

The restoration scheme proposed for the extension area in the lodged planning application does include agricultural land, woodland blocks and scrub with a lake of some 9.2 hectares representing the natural groundwater level. The proposed restoration of the MIN40 site reflects the permitted restoration of the existing Grandcourt Quarry site and has been designed to complement and fit in with this overall restoration which is dictated by the geotechnical assessment and local geological circumstances.

The overburden volumes in the Grandcourt extension area and volumes required to restore the site as per the submitted proposed restoration scheme are as follows:

Overburden materials identified by drilling programmes:
Soils 78,000m3
Carstone 1,300,000 m3
Clay 420,000 m3
Material required to create the proposed landform in the MIN40 site:
Material required to create 1:4 slopes on final sand and overburden faces 1,020,000 m3
Material required to create embankment for bridleway and farm access 736,000 m3
Given the material balance for the site as shown above and with no proposal to import any material for restoration or other purposes, the final landform and restoration scheme proposed is the only one which can reasonably be implemented. The MIN40 site is not suitable for heathland restoration.

The submitted Environmental Statement contains a hydrogeological risk assessment which identifies potential impacts on groundwater including the perched water table in the Carstone. The proposed eastern extension will have little or no additional significant impacts to the north, south and west. The area over which drawdown in groundwater levels will occur will increase to the east, but no water sensitive receptors have been identified within the predicted area of influence in this direction. It is proposed that the potential additional impacts to surface and groundwater are monitored and controlled via a minor revision of the existing Water Management Plan.
There is electricity infrastructure within MIN40 site
Subject to the above comments Sibelco supports the inclusion of MIN40 as a Specific Site.

Question 68: Proposed Site SIL 01 'land at Mintlyn South, Bawsey'
Sibelco supports the inclusion of SIL01 as a Specific Site

Question 69: Area of Search AOS E 'land to the north of Shouldham'
Area of Search E
Sibelco supports the inclusion of Area E as an Area of Search for silica sand

Question 73: Policy MP13: 'Areas of Search for silica sand extraction'
Sibelco supports Policy MP13 on Areas of Search for silica sand, subject to our response to Question 9

Question 74: Proposed Site SIL 02 'land at Shouldham and Marham'
Sibelco supports the inclusion of SIL02 as an allocated site and would propose that given the promoters knowledge of the local geology, the site should be allocated as a Specific Site. Further silica sand provision will be required at the end of the Plan period
The National Planning Practice Guidance says:
a) designating Specific Sites - where viable mineral resources are known to exist, landowners are supportive of minerals development and the proposal is likely to be acceptable in planning terms ....

This definition applies to SIL02

Question 1: 'Minerals and Waste Local Plan Vision'
The Vision should refer the provision of minerals supply to be in accordance with and as required by National Policy
Mineral Safeguarding should refer to paragraph 182 of the revised National Planning Policy Framework such that the applicant for adjacent development ('agent of change') should be required to provide suitable mitigation to take account of existing and allocated development.

Question 3: 'Minerals Strategic Objectives'
The following amendments are proposed (in CAPITALS):
MSO2. To provide a steady and adequate supply of industrial minerals by identifying adequate mineral extraction sites/areas within Norfolk sufficient to meet the forecast need AND STOCKS OF PERMITTED RESERVES OF SILICA SAND OF AT LEAST 10 YEARS PRODUCTION FOR INDIVIDUAL SILICA SITES AND AT LEAST 15 YEARS FOR SILICA SAND SITES WHERE SIGNIFICANT NEW CAPITAL IS REQUIRED and safeguarding existing infrastructure. (To accord with NPPF 2018 paragraph 208 footnote 68)

MSO4. To safeguard silica sand, carstone, and sand and gravel resources for future use. Avoiding unnecessary sterilisation by encouraging the extraction of minerals prior to other development taking place where practicable and using minerals in construction on the land from which they are extracted. THE 'AGENT OF CHANGE' PRINCIPLE WILL BE APPLIED TO ANY NEW PROPOSED DEVELOPMENT IMPACTING ON SAFEGUARDED AREAS OR SITES.

MSO5. To promote the sustainable transport of minerals by rail, road and water, including the safeguarding of railheads and wharfs for the import of minerals to and export of minerals from Norfolk. THE 'AGENT OF CHANGE' PRINCIPLE WILL BE APPLIED TO ANY NEW PROPOSED DEVELOPMENT IMPACTING ON SAFEGUARDED SITES.

MSO8. To ensure that mineral development addresses and minimises the impacts it will have on climate change by: REDUCING greenhouse gas emissions during the winning, working and handling of minerals, SEEK TO PROVIDE sustainable patterns of minerals transportation, and WHERE POSSIBLE integrating features consistent with climate change mitigation and adaption into the design of restoration and aftercare proposals.
MSO9. To positively contribute to the natural, built and historic environments with high quality, progressive and expedient restoration to achieve a beneficial after use. The after use will protect and enhance the environment, including landscape and biodiversity improvements.

Comment: the restoration of mineral sites can deliver landforms to facilitate different after uses of land, however mineral planning has no role in the after use of itself.

MSO10. WHERE PRACTICAL to increase public access to the countryside and enhance biodiversity through enhancing the amenity value of land when restoring extraction sites.

Question 4: Policy MW1 'Presumption in favour of sustainable development'
This policy is supported including the recognition in the preamble that the three pillars of sustainability have equal standing.
 
Question 5: Policy MW2 'Development Management Criteria'
Where appropriate AND PRACTICAL, enhancement of the environment would be sought, including, but not exclusively, the enhancement of the Public Rights of Way Network, creation of recreation opportunities and enhancement of the natural, historic and built environment and surrounding landscapes.

Question 6: Policy MW3 'transport'
WHERE PRACTICAL AND REALISTIC measures to reduce car travel to the site by workers and visitors and encourage walking, cycling and use of public transport.

Question 7: Policy MW4 'climate change mitigation and adaption'
b) be planned so as to REDUCE carbon dioxide and methane emissions ON A SITE UNIT BASIS
c) endeavour to SOURCE a minimum of 10 per cent of the energy used on site from decentralised and renewable or low-carbon sources.
d) WHERE PRACTICAL AND RELEVANT to demonstrate the use of sustainable drainage systems, water harvesting from impermeable surfaces and layouts that accommodate waste water recycling
e) WHERE RELEVANT TO take account of potential changes in climate including rising sea levels and coastal erosion
g) incorporate proposals for sustainable travel, including travel plans where PRACTICAL AND appropriate.

Question 9: Policy MW6 'agricultural soils'
This policy should be applied flexibly since minerals can clearly only be worked where they exist and for silica sand for glass making the potential land is further restricted by virtue of the scarcity of this mineral.

Question 27: Policy MP1 'Provision for minerals extraction'
No as it does not accord with National Policy and is unsound. Suggested wording for silica sand:
STOCKS OF PERMITTED RESERVES for silica sand will be maintained at 10 years' PRODUCTION FOR EACH SILICA SAND SITE. Sufficient sites and/or areas to deliver at least 12,380,000 tonnes of silica sand will be allocated TO THE END OF THE PLAN PERIOD WITH FURTHER PROVISION TO ENSURE A STOCK OF PERMITTED RESERVES BEYOND THE PLAN PERIOD.
In the table on page 63 in the preamble to Policy MP1 is should read:
B Silica sand permitted reserve at 31/12/2016

Question 28: Policy MP2 'Spatial strategy for minerals extraction'
"Within the resource areas identified on the key diagram, specific sites or preferred areas for silica sand extraction should be located where they are able to access the existing processing plant and railhead at Leziate via conveyor, pipeline or off-public highway routes". This contradicts wording in proposed Policy MP13 and the Single Issue Silica Sand Review of the Minerals Site Specific Allocations DPD (adopted in December 2017) which discussed highway routes from Areas of Search to the Leziate processing site.
There should be no buffers applied to the so-called planning constraints. The acceptability or not of approaching such constraints will be a matter for the EIA.
Agricultural land grades 1 and 2 should not be excluded. This contradicts Policy MW6 which should in all circumstances be adopted and applied flexibly.

Question 33: Policy MP7 'Progressive working, restoration and after-use'
After use is noted several times in the policy but after use is not a matter for mineral planning.
There is no mention of restoration to agricultural land
Any important geology or geomorphology on the site will be retained in sample exposures for study purposes ONLY WHERE PRACTICAL AND SAFE TO DO SO

Question 36: Policy MP10 'Safeguarding of port and rail facilities, and facilities for the manufacture of concrete, asphalt and recycled materials'
The 'agent of change' principle will be applied to all development in proximity to safeguarded sites.


Question 37: Policy M11 'Mineral Safeguarding Areas and Mineral Consultation Areas'
The 'agent of change' principle will be applied to all development in proximity to safeguarded sites.

Question 67: Proposed Site MIN 40 'land east of Grandcourt Farm, East Winch'
The site is allocated as a specific site for silica sand extraction in the Adopted in the Core Strategy and Minerals and Waste Development Management Policies Development Plan Document 2010-2026 (adopted September 2011) and identified in the Minerals Site Specific Allocations Development Plan Document (DPD) (adopted October 2013, amendments adopted December 2017).

The Initial conclusion on the MIN40 site in the May 2018 consultation document notes that "the site is considered suitable for allocation for silica sand extraction, subject to any planning application addressing the requirements below: [requirements are detailed in the Initial Consultation document]

Sibelco has submitted a planning application for an extension of Grandcourt Quarry into the MIN40 site and has the following comments on some of the "requirements" noted in the Initial Consultation document.

* Opportunities during working for any geodiversity assets to be studied, and if compatible with the landscape and ecology objectives, an open face to be retained as part of the restoration scheme

The following amendments are proposed (in CAPITALS):
MSO2. To provide a steady and adequate supply of industrial minerals by identifying adequate mineral extraction sites/areas within Norfolk sufficient to meet the forecast need AND STOCKS OF PERMITTED RESERVES OF SILICA SAND OF AT LEAST 10 YEARS PRODUCTION FOR INDIVIDUAL SILICA SITES AND AT LEAST 15 YEARS FOR SILICA SAND SITES WHERE SIGNIFICANT NEW CAPITAL IS REQUIRED and safeguarding existing infrastructure. (To accord with NPPF 2018 paragraph 208 footnote 68)

MSO4. To safeguard silica sand, carstone, and sand and gravel resources for future use. Avoiding unnecessary sterilisation by encouraging the extraction of minerals prior to other development taking place where practicable and using minerals in construction on the land from which they are extracted. THE 'AGENT OF CHANGE' PRINCIPLE WILL BE APPLIED TO ANY NEW PROPOSED DEVELOPMENT IMPACTING ON SAFEGUARDED AREAS OR SITES.

MSO5. To promote the sustainable transport of minerals by rail, road and water, including the safeguarding of railheads and wharfs for the import of minerals to and export of minerals from Norfolk. THE 'AGENT OF CHANGE' PRINCIPLE WILL BE APPLIED TO ANY NEW PROPOSED DEVELOPMENT IMPACTING ON SAFEGUARDED SITES.

MSO8. To ensure that mineral development addresses and minimises the impacts it will have on climate change by: REDUCING greenhouse gas emissions during the winning, working and handling of minerals, SEEK TO PROVIDE sustainable patterns of minerals transportation, and WHERE POSSIBLE integrating features consistent with climate change mitigation and adaption into the design of restoration and aftercare proposals.
MSO9. To positively contribute to the natural, built and historic environments with high quality, progressive and expedient restoration to achieve a beneficial after use. The after use will protect and enhance the environment, including landscape and biodiversity improvements.

Comment: the restoration of mineral sites can deliver landforms to facilitate different after uses of land, however mineral planning has no role in the after use of itself.

MSO10. WHERE PRACTICAL to increase public access to the countryside and enhance biodiversity through enhancing the amenity value of land when restoring extraction sites.

Question 4: Policy MW1 'Presumption in favour of sustainable development'
This policy is supported including the recognition in the preamble that the three pillars of sustainability have equal standing.
 
Question 5: Policy MW2 'Development Management Criteria'
Where appropriate AND PRACTICAL, enhancement of the environment would be sought, including, but not exclusively, the enhancement of the Public Rights of Way Network, creation of recreation opportunities and enhancement of the natural, historic and built environment and surrounding landscapes.

Question 6: Policy MW3 'transport'
WHERE PRACTICAL AND REALISTIC measures to reduce car travel to the site by workers and visitors and encourage walking, cycling and use of public transport.

Question 7: Policy MW4 'climate change mitigation and adaption'
b) be planned so as to REDUCE carbon dioxide and methane emissions ON A SITE UNIT BASIS
c) endeavour to SOURCE a minimum of 10 per cent of the energy used on site from decentralised and renewable or low-carbon sources.
d) WHERE PRACTICAL AND RELEVANT to demonstrate the use of sustainable drainage systems, water harvesting from impermeable surfaces and layouts that accommodate waste water recycling
e) WHERE RELEVANT TO take account of potential changes in climate including rising sea levels and coastal erosion
g) incorporate proposals for sustainable travel, including travel plans where PRACTICAL AND appropriate.

Question 9: Policy MW6 'agricultural soils'
This policy should be applied flexibly since minerals can clearly only be worked where they exist and for silica sand for glass making the potential land is further restricted by virtue of the scarcity of this mineral.

Question 27: Policy MP1 'Provision for minerals extraction'
No as it does not accord with National Policy and is unsound. Suggested wording for silica sand:
STOCKS OF PERMITTED RESERVES for silica sand will be maintained at 10 years' PRODUCTION FOR EACH SILICA SAND SITE. Sufficient sites and/or areas to deliver at least 12,380,000 tonnes of silica sand will be allocated TO THE END OF THE PLAN PERIOD WITH FURTHER PROVISION TO ENSURE A STOCK OF PERMITTED RESERVES BEYOND THE PLAN PERIOD.
In the table on page 63 in the preamble to Policy MP1 is should read:
B Silica sand permitted reserve at 31/12/2016

Question 28: Policy MP2 'Spatial strategy for minerals extraction'
"Within the resource areas identified on the key diagram, specific sites or preferred areas for silica sand extraction should be located where they are able to access the existing processing plant and railhead at Leziate via conveyor, pipeline or off-public highway routes". This contradicts wording in proposed Policy MP13 and the Single Issue Silica Sand Review of the Minerals Site Specific Allocations DPD (adopted in December 2017) which discussed highway routes from Areas of Search to the Leziate processing site.
There should be no buffers applied to the so-called planning constraints. The acceptability or not of approaching such constraints will be a matter for the EIA.
Agricultural land grades 1 and 2 should not be excluded. This contradicts Policy MW6 which should in all circumstances be adopted and applied flexibly.

Question 33: Policy MP7 'Progressive working, restoration and after-use'
After use is noted several times in the policy but after use is not a matter for mineral planning.
There is no mention of restoration to agricultural land
Any important geology or geomorphology on the site will be retained in sample exposures for study purposes ONLY WHERE PRACTICAL AND SAFE TO DO SO

Question 36: Policy MP10 'Safeguarding of port and rail facilities, and facilities for the manufacture of concrete, asphalt and recycled materials'
The 'agent of change' principle will be applied to all development in proximity to safeguarded sites.


Question 37: Policy M11 'Mineral Safeguarding Areas and Mineral Consultation Areas'
The 'agent of change' principle will be applied to all development in proximity to safeguarded sites.

Question 67: Proposed Site MIN 40 'land east of Grandcourt Farm, East Winch'
The site is allocated as a specific site for silica sand extraction in the Adopted in the Core Strategy and Minerals and Waste Development Management Policies Development Plan Document 2010-2026 (adopted September 2011) and identified in the Minerals Site Specific Allocations Development Plan Document (DPD) (adopted October 2013, amendments adopted December 2017).

The Initial conclusion on the MIN40 site in the May 2018 consultation document notes that "the site is considered suitable for allocation for silica sand extraction, subject to any planning application addressing the requirements below: [requirements are detailed in the Initial Consultation document]

Sibelco has submitted a planning application for an extension of Grandcourt Quarry into the MIN40 site and has the following comments on some of the "requirements" noted in the Initial Consultation document.

* Opportunities during working for any geodiversity assets to be studied, and if compatible with the landscape and ecology objectives, an open face to be retained as part of the restoration scheme

Sibelco will examine working faces during operation and can take photographic records of any features of note observed, if any. Following extraction being completed in each phase, Carstone material will be used to cover and stabilise the Leziate Sand faces to create safe long term slopes as described in Appendix 9 to the submitted Planning Statement (Geotechnical Design and Assessment).
Opportunities could be afforded during working to geology students to inspect and study open faces and overburden areas under supervision where consistent with health and safety of the site. Bearing in mind the proposed open water restoration with peripheral broadleaved woodland and shrub/grassland it is not been possible to incorporate any open face in the restoration, which would in addition be difficult to maintain safely due to the nature of the geology, which makes it vulnerable to erosion and a potential safety hazard.

* A restoration scheme incorporating heathland or a heathland/arable mix with blocks of woodland which provides biodiversity gains and does not result in permanent dewatering of a perched water table in the carstone aquifer if one is identified in a hydrogeological risk assessment
*
The lodged planning application proposes a combination of restored areas of open water (51.4%), native broadleaved woodland (8.8%), hedgerows (increase of 920 linear metres), scrub & species rich grassland (20.7%), agricultural land (15.2%) and public rights of way for the restored site with biodiversity gains. The hydrogeological assessment of the site showed there were no significant impacts on the perched water table in the Carstone as a result of working and restoration.

The proposed restoration is primarily to water since the excavation will be several metres below the natural groundwater level in order to release the proven mineral. It will not be possible to deliver a dry restoration using on-site overburden materials. For the same reason it will not be possible to deliver a requirement of MIN40, which is to incorporate heathland into the restoration. The proposed site for the former Site Specific Allocations DPD was considerably reduced in area at examination which removed land which may have been suitable for heathland restoration. The much reduced currently allocated area reflects very closely the area of excavation. Once the restored margin areas are accounted for, the remaining area of land restoration is at the lake margins on mostly slopes to the water's edge, which is not suitable for heathland. Significant heathland restoration has been delivered by the Applicant on former mineral sites to the north of Middleton Stop Drain.

The proposed restoration scheme is shown on the submitted restoration drawings. This scheme has been designed with due regard for the precise setting of the site; the local geology; local topography; position of the natural groundwater table and the volumes of different overburden materials identified within the site by drilling programmes.

Policy Min 40 states that a restoration scheme for the site should seek to incorporate heathland or a heathland/arable mix with blocks of woodland which provides biodiversity gains. Given the volumes of sand and overburden materials present and the position of the local groundwater table this is not possible in its entirety in this case.

Sibelco has restored former mineral extraction area locally to heathland (for example Wicken North and Wicken South), however, these areas have very different physical parameters which allowed such restoration to be designed and implemented. Wicken North and Wicken South are located on lower ground and had relatively low sand to overburden ratios which allowed significant areas to be restored to generally level ground above the local groundwater level. Grandcourt Quarry extension is located on higher ground, has a different ratio of sand to overburden (higher ratio) and a different relationship of ground levels to groundwater level. Final restored slopes must be stable in the long term and at the same time utilise only suitable overburden materials from the site (there are no proposals to import any materials from elsewhere to effect the restoration). Tailings materials from the mineral washing (silts and lays) are unsuitable for restoration in this area due to high water content of the tailings and distance from the processing plant. The company has sufficient permitted tailings space elsewhere on the wider site.

The restoration scheme proposed for the extension area in the lodged planning application does include agricultural land, woodland blocks and scrub with a lake of some 9.2 hectares representing the natural groundwater level. The proposed restoration of the MIN40 site reflects the permitted restoration of the existing Grandcourt Quarry site and has been designed to complement and fit in with this overall restoration which is dictated by the geotechnical assessment and local geological circumstances.

The overburden volumes in the Grandcourt extension area and volumes required to restore the site as per the submitted proposed restoration scheme are as follows:

Overburden materials identified by drilling programmes:
Soils 78,000m3
Carstone 1,300,000 m3
Clay 420,000 m3
Material required to create the proposed landform in the MIN40 site:
Material required to create 1:4 slopes on final sand and overburden faces 1,020,000 m3
Material required to create embankment for bridleway and farm access 736,000 m3
Given the material balance for the site as shown above and with no proposal to import any material for restoration or other purposes, the final landform and restoration scheme proposed is the only one which can reasonably be implemented. The MIN40 site is not suitable for heathland restoration.

The submitted Environmental Statement contains a hydrogeological risk assessment which identifies potential impacts on groundwater including the perched water table in the Carstone. The proposed eastern extension will have little or no additional significant impacts to the north, south and west. The area over which drawdown in groundwater levels will occur will increase to the east, but no water sensitive receptors have been identified within the predicted area of influence in this direction. It is proposed that the potential additional impacts to surface and groundwater are monitored and controlled via a minor revision of the existing Water Management Plan.
There is electricity infrastructure within MIN40 site

Opportunities could be afforded during working to geology students to inspect and study open faces and overburden areas under supervision where consistent with health and safety of the site. Bearing in mind the proposed open water restoration with peripheral broadleaved woodland and shrub/grassland it is not been possible to incorporate any open face in the restoration, which would in addition be difficult to maintain safely due to the nature of the geology, which makes it vulnerable to erosion and a potential safety hazard.

* A restoration scheme incorporating heathland or a heathland/arable mix with blocks of woodland which provides biodiversity gains and does not result in permanent dewatering of a perched water table in the carstone aquifer if one is identified in a hydrogeological risk assessment
*
The lodged planning application proposes a combination of restored areas of open water (51.4%), native broadleaved woodland (8.8%), hedgerows (increase of 920 linear metres), scrub & species rich grassland (20.7%), agricultural land (15.2%) and public rights of way for the restored site with biodiversity gains. The hydrogeological assessment of the site showed there were no significant impacts on the perched water table in the Carstone as a result of working and restoration.

The proposed restoration is primarily to water since the excavation will be several metres below the natural groundwater level in order to release the proven mineral. It will not be possible to deliver a dry restoration using on-site overburden materials. For the same reason it will not be possible to deliver a requirement of MIN40, which is to incorporate heathland into the restoration. The proposed site for the former Site Specific Allocations DPD was considerably reduced in area at examination which removed land which may have been suitable for heathland restoration. The much reduced currently allocated area reflects very closely the area of excavation. Once the restored margin areas are accounted for, the remaining area of land restoration is at the lake margins on mostly slopes to the water's edge, which is not suitable for heathland. Significant heathland restoration has been delivered by the Applicant on former mineral sites to the north of Middleton Stop Drain.

The proposed restoration scheme is shown on the submitted restoration drawings. This scheme has been designed with due regard for the precise setting of the site; the local geology; local topography; position of the natural groundwater table and the volumes of different overburden materials identified within the site by drilling programmes.

Policy Min 40 states that a restoration scheme for the site should seek to incorporate heathland or a heathland/arable mix with blocks of woodland which provides biodiversity gains. Given the volumes of sand and overburden materials present and the position of the local groundwater table this is not possible in its entirety in this case.

Sibelco has restored former mineral extraction area locally to heathland (for example Wicken North and Wicken South), however, these areas have very different physical parameters which allowed such restoration to be designed and implemented. Wicken North and Wicken South are located on lower ground and had relatively low sand to overburden ratios which allowed significant areas to be restored to generally level ground above the local groundwater level. Grandcourt Quarry extension is located on higher ground, has a different ratio of sand to overburden (higher ratio) and a different relationship of ground levels to groundwater level. Final restored slopes must be stable in the long term and at the same time utilise only suitable overburden materials from the site (there are no proposals to import any materials from elsewhere to effect the restoration). Tailings materials from the mineral washing (silts and lays) are unsuitable for restoration in this area due to high water content of the tailings and distance from the processing plant. The company has sufficient permitted tailings space elsewhere on the wider site.

The restoration scheme proposed for the extension area in the lodged planning application does include agricultural land, woodland blocks and scrub with a lake of some 9.2 hectares representing the natural groundwater level. The proposed restoration of the MIN40 site reflects the permitted restoration of the existing Grandcourt Quarry site and has been designed to complement and fit in with this overall restoration which is dictated by the geotechnical assessment and local geological circumstances.

The overburden volumes in the Grandcourt extension area and volumes required to restore the site as per the submitted proposed restoration scheme are as follows:

Overburden materials identified by drilling programmes:
Soils 78,000m3
Carstone 1,300,000 m3
Clay 420,000 m3
Material required to create the proposed landform in the MIN40 site:
Material required to create 1:4 slopes on final sand and overburden faces 1,020,000 m3
Material required to create embankment for bridleway and farm access 736,000 m3
Given the material balance for the site as shown above and with no proposal to import any material for restoration or other purposes, the final landform and restoration scheme proposed is the only one which can reasonably be implemented. The MIN40 site is not suitable for heathland restoration.

The submitted Environmental Statement contains a hydrogeological risk assessment which identifies potential impacts on groundwater including the perched water table in the Carstone. The proposed eastern extension will have little or no additional significant impacts to the north, south and west. The area over which drawdown in groundwater levels will occur will increase to the east, but no water sensitive receptors have been identified within the predicted area of influence in this direction. It is proposed that the potential additional impacts to surface and groundwater are monitored and controlled via a minor revision of the existing Water Management Plan.
There is electricity infrastructure within MIN40 site
Subject to the above comments Sibelco supports the inclusion of MIN40 as a Specific Site.

Question 68: Proposed Site SIL 01 'land at Mintlyn South, Bawsey'
Sibelco supports the inclusion of SIL01 as a Specific Site

Question 69: Area of Search AOS E 'land to the north of Shouldham'
Area of Search E
Sibelco supports the inclusion of Area E as an Area of Search for silica sand

Question 73: Policy MP13: 'Areas of Search for silica sand extraction'
Sibelco supports Policy MP13 on Areas of Search for silica sand, subject to our response to Question 9

Question 74: Proposed Site SIL 02 'land at Shouldham and Marham'
Sibelco supports the inclusion of SIL02 as an allocated site and would propose that given the promoters knowledge of the local geology, the site should be allocated as a Specific Site. Further silica sand provision will be required at the end of the Plan period
The National Planning Practice Guidance says:
a) designating Specific Sites - where viable mineral resources are known to exist, landowners are supportive of minerals development and the proposal is likely to be acceptable in planning terms ....

This definition applies to SIL02

Question 1: 'Minerals and Waste Local Plan Vision'
The Vision should refer the provision of minerals supply to be in accordance with and as required by National Policy
Mineral Safeguarding should refer to paragraph 182 of the revised National Planning Policy Framework such that the applicant for adjacent development ('agent of change') should be required to provide suitable mitigation to take account of existing and allocated development.

Question 3: 'Minerals Strategic Objectives'
The following amendments are proposed (in CAPITALS):
MSO2. To provide a steady and adequate supply of industrial minerals by identifying adequate mineral extraction sites/areas within Norfolk sufficient to meet the forecast need AND STOCKS OF PERMITTED RESERVES OF SILICA SAND OF AT LEAST 10 YEARS PRODUCTION FOR INDIVIDUAL SILICA SITES AND AT LEAST 15 YEARS FOR SILICA SAND SITES WHERE SIGNIFICANT NEW CAPITAL IS REQUIRED and safeguarding existing infrastructure. (To accord with NPPF 2018 paragraph 208 footnote 68)

MSO4. To safeguard silica sand, carstone, and sand and gravel resources for future use. Avoiding unnecessary sterilisation by encouraging the extraction of minerals prior to other development taking place where practicable and using minerals in construction on the land from which they are extracted. THE 'AGENT OF CHANGE' PRINCIPLE WILL BE APPLIED TO ANY NEW PROPOSED DEVELOPMENT IMPACTING ON SAFEGUARDED AREAS OR SITES.

MSO5. To promote the sustainable transport of minerals by rail, road and water, including the safeguarding of railheads and wharfs for the import of minerals to and export of minerals from Norfolk. THE 'AGENT OF CHANGE' PRINCIPLE WILL BE APPLIED TO ANY NEW PROPOSED DEVELOPMENT IMPACTING ON SAFEGUARDED SITES.

MSO8. To ensure that mineral development addresses and minimises the impacts it will have on climate change by: REDUCING greenhouse gas emissions during the winning, working and handling of minerals, SEEK TO PROVIDE sustainable patterns of minerals transportation, and WHERE POSSIBLE integrating features consistent with climate change mitigation and adaption into the design of restoration and aftercare proposals.
MSO9. To positively contribute to the natural, built and historic environments with high quality, progressive and expedient restoration to achieve a beneficial after use. The after use will protect and enhance the environment, including landscape and biodiversity improvements.

Comment: the restoration of mineral sites can deliver landforms to facilitate different after uses of land, however mineral planning has no role in the after use of itself.

MSO10. WHERE PRACTICAL to increase public access to the countryside and enhance biodiversity through enhancing the amenity value of land when restoring extraction sites.

Question 4: Policy MW1 'Presumption in favour of sustainable development'
This policy is supported including the recognition in the preamble that the three pillars of sustainability have equal standing.
 
Question 5: Policy MW2 'Development Management Criteria'
Where appropriate AND PRACTICAL, enhancement of the environment would be sought, including, but not exclusively, the enhancement of the Public Rights of Way Network, creation of recreation opportunities and enhancement of the natural, historic and built environment and surrounding landscapes.

Question 6: Policy MW3 'transport'
WHERE PRACTICAL AND REALISTIC measures to reduce car travel to the site by workers and visitors and encourage walking, cycling and use of public transport.

Question 7: Policy MW4 'climate change mitigation and adaption'
b) be planned so as to REDUCE carbon dioxide and methane emissions ON A SITE UNIT BASIS
c) endeavour to SOURCE a minimum of 10 per cent of the energy used on site from decentralised and renewable or low-carbon sources.
d) WHERE PRACTICAL AND RELEVANT to demonstrate the use of sustainable drainage systems, water harvesting from impermeable surfaces and layouts that accommodate waste water recycling
e) WHERE RELEVANT TO take account of potential changes in climate including rising sea levels and coastal erosion
g) incorporate proposals for sustainable travel, including travel plans where PRACTICAL AND appropriate.

Question 9: Policy MW6 'agricultural soils'
This policy should be applied flexibly since minerals can clearly only be worked where they exist and for silica sand for glass making the potential land is further restricted by virtue of the scarcity of this mineral.

Question 27: Policy MP1 'Provision for minerals extraction'
No as it does not accord with National Policy and is unsound. Suggested wording for silica sand:
STOCKS OF PERMITTED RESERVES for silica sand will be maintained at 10 years' PRODUCTION FOR EACH SILICA SAND SITE. Sufficient sites and/or areas to deliver at least 12,380,000 tonnes of silica sand will be allocated TO THE END OF THE PLAN PERIOD WITH FURTHER PROVISION TO ENSURE A STOCK OF PERMITTED RESERVES BEYOND THE PLAN PERIOD.
In the table on page 63 in the preamble to Policy MP1 is should read:
B Silica sand permitted reserve at 31/12/2016

Question 28: Policy MP2 'Spatial strategy for minerals extraction'
"Within the resource areas identified on the key diagram, specific sites or preferred areas for silica sand extraction should be located where they are able to access the existing processing plant and railhead at Leziate via conveyor, pipeline or off-public highway routes". This contradicts wording in proposed Policy MP13 and the Single Issue Silica Sand Review of the Minerals Site Specific Allocations DPD (adopted in December 2017) which discussed highway routes from Areas of Search to the Leziate processing site.
There should be no buffers applied to the so-called planning constraints. The acceptability or not of approaching such constraints will be a matter for the EIA.
Agricultural land grades 1 and 2 should not be excluded. This contradicts Policy MW6 which should in all circumstances be adopted and applied flexibly.

Question 33: Policy MP7 'Progressive working, restoration and after-use'
After use is noted several times in the policy but after use is not a matter for mineral planning.
There is no mention of restoration to agricultural land
Any important geology or geomorphology on the site will be retained in sample exposures for study purposes ONLY WHERE PRACTICAL AND SAFE TO DO SO

Question 36: Policy MP10 'Safeguarding of port and rail facilities, and facilities for the manufacture of concrete, asphalt and recycled materials'
The 'agent of change' principle will be applied to all development in proximity to safeguarded sites.


Question 37: Policy M11 'Mineral Safeguarding Areas and Mineral Consultation Areas'
The 'agent of change' principle will be applied to all development in proximity to safeguarded sites.

Question 67: Proposed Site MIN 40 'land east of Grandcourt Farm, East Winch'
The site is allocated as a specific site for silica sand extraction in the Adopted in the Core Strategy and Minerals and Waste Development Management Policies Development Plan Document 2010-2026 (adopted September 2011) and identified in the Minerals Site Specific Allocations Development Plan Document (DPD) (adopted October 2013, amendments adopted December 2017).

The Initial conclusion on the MIN40 site in the May 2018 consultation document notes that "the site is considered suitable for allocation for silica sand extraction, subject to any planning application addressing the requirements below: [requirements are detailed in the Initial Consultation document]

Sibelco has submitted a planning application for an extension of Grandcourt Quarry into the MIN40 site and has the following comments on some of the "requirements" noted in the Initial Consultation document.

* Opportunities during working for any geodiversity assets to be studied, and if compatible with the landscape and ecology objectives, an open face to be retained as part of the restoration scheme

Sibelco will examine working faces during operation and can take photographic records of any features of note observed, if any.
