Locationand General Description of Site

1.6.1 The site was put forward by the company as an extension to the existing permitted area at Potlocks Farm. However, it lies to the south across the A5132 and the River Trent and is not physically connected to the Potlocks site. In addition, it has been agreed with Hanson's that the planning permission for the Potlocks site will be revoked as and when planning permission for the Weston extension of Shardlow Quarry is issued. It has, therefore, been evaluated as a new site. The site is located in the Trent Valley. It is in agricultural use, primarily grazing, and measures some 177 ha. Its boundaries are defined by the River Trent in the north, field boundaries in the south and west and a track to the east. An ancient route of the River Trent runs through the middle of the site.

Resources (yield, annual output, depth of deposit)

1.6.2 The site is located on the alluvial/terrace deposits of the Trent Valley. It is proposed to work some 11,200,000 tonnes of sand and gravel from a net excavation area measuring 142 ha i.e. an estimated yield of tonnes per hectare 78,900 tph. The average depth of the deposit is 5.1 metres

End Use of and Market for Mineral

1.6.3 The end uses and markets are assumed to be the same as Shardlow which this site is intended to replace. The mineral would be used to supply coarse aggregate suitable for most construction purposes and fine aggregate including high quality concrete sand, asphalt sand and mortar sand. The main market areas for the mineral are the Derby and Nottingham areas generally within 25 miles of the site.

Timing and Phasing

1.6.4 The company view this site as a long term replacement for the workings at Shardlow and therefore the level of reserves at Shardlow directly impacts on the timing of the commencement of this operation. The operator estimates that the annual output of the plant would be around 600,000 tpa. The estimated yield figure of 11,200,000 tonnes gives a lifespan for the site of approximately 18 years. Working would commence after reserves have been exhausted at Shardlow. It is estimated that existing permitted reserves at Shardlow will be exhausted by 2024.

Plant & Access Arrangements

1.6.5 It was originally considered that the site could be worked with the mineral being processed through the plant that would be erected at the Potlocks Farm site. Under this arrangement vehicles used to transport the processed mineral to end users would also continue to use the Potlocks access onto the A5132. For the reasons stated above that site will not now be worked and alternative new plant and access arrangements would need to be developed. This would require the construction of a new bridge across the River Trent. The A5132 provides good links to the A50/A38/M1.

Relevant History

1.6.6 Planning permission for the extraction of sand and gravel from Potlocks House Farm site, lying to the east of Willington Power Station was granted in 1972 to commence within 15 years. The date by which the development must be begun has been extended by successive planning permissions the last being in 1995; the development must be begun by 2010. Following the development of proposals for the Weston extension to the Shardlow the Potlocks site has been put on hold and the planning permission will be revoked when the Weston permission is issued.

 

SITE ASSESSMENT

ECONOMIC CONSIDERATIONS

Existing Infrastructure

ECONOMIC TOTAL 18/24

 

SOCIAL CONSIDERATIONS

Visual Intrusion

1.6.14 The site is visible from a number of surrounding locations. The north-western part of the site is visible from a number of properties on the southern edge of Willington, approximately 300 away with open views across the river. The western part of the site is visible from a number of properties on the northern edge of Repton village, including Repton School and grounds, which lie some 50 - 100 m from the southern site boundary on slightly higher land above the floodplain. The north-eastern part of the site is visible from some properties in Twyford village, approximately 300 m away, which have open views across the river. Individual properties close to the site include Brook Farm plus one or two nearby residences which lie some 150 - 200m from south-astern boundary and a nursing home which lies 10/20 m from eastern boundary. The nursing home whilst close to the eastern boundary of the site is well screened by trees within its curtilage. A few individual properties, including Brook farm, have open views across the north-eastern part of the site. There are two footpaths, which pass through the site and workings would be prominent from these. The site is not visible from Milton village which lies some 500 m from the south-eastern boundary of the site beyond Askew Hill.

ASSESSMENT (--) The site has many visually sensitive receptors and/or large parts (or more than one part) of the site will be visible

Noise

1.6.15 Noise is likely to be generated by the operations to be carried out at the site, chiefly from soil and overburden movement, sand and gravel extraction and transportation of raw mineral within the site by conveyor or dump trucks to a processing plant. Additional noise would be created by vehicles transporting the processed mineral from the site to the end users. The nearest noise sensitive property is the nursing home, which lies some 10/20 metres from the eastern boundary of the site. Brook Farm and surrounding residences lie within 150 - 200 m of the south-eastern boundary. Many properties located within Twyford village, the southern part of Willington and the northern part of Repton village lie within 500 metres of the site boundary.

ASSESSMENT (--) The site has manynoise sensitive receptors within 500m from the boundary of the site

Nuisance Dust

1.6.16 Dust tends not to be a major problem associated with the extraction of river gravels due to the wet nature of the mineral which acts as a natural dust suppressant. The nearest dust sensitive property is the nursing home which lies some 10/20 metres from eastern boundary. Brook Farm and surrounding residences lie within 150 - 200 m of the south-eastern boundary. Many properties located within Twyford village, the southern part of Willington and the northern part of Repton village lie within 500 metres of the site boundary.

ASSESSMENT (--) The site has many dust sensitive receptors within 500m from the boundary of the site

Air Quality/Human Health

1.6.17 The site does not contain lie within or within 1000m of any designated Air Quality Management Areas in which air quality objectives are not being met, which so far in Derby and Derbyshire have been associated with road traffic pollution.

ASSESSMENT (+) The site does not lie within 1000m of an AQMA.

 

Transport - Local Amenity

1.6.18 From the processing plant all mineral will be transported to market by road. The A5132 provides good links to the A50/A38/M1 however lorries travelling west from the site would pass through the village of Willington.

ASSESSMENT(--)Heavy goods vehicles would pass many sensitive receptors to reach the main market area

Potential Benefits of the Proposed After-Use

1.6.19 The mineral operator suggests that, given that the site lies outside the 13 km safeguarding area for East Midlands Airport and that ALC is predominantly poorer, the site is suitable for full reinstatement to agriculture or to water based nature conservation or a combination of both. The MPA considers that there is limited requirement for biodiversity enhancement within the site. Additionally, the proposed site accords with the established landscape character and is in good condition where the preference is for conservation. Water based nature conservation would conflict with the high potential risk of birdstrike. There may be an opportunity to create a strategic multi-user route, identified in the South Derbyshire Greenways Strategy, as a means of connecting the currently severed communities of Repton and Willington. The route identified follows the bridleway south of the river across the western part of this site. A new multi-user bridge would be required to cross the River Trent at this point.

ASSESSMENT(-) One of the benefits (social, economic, and environmental) arising from the proposed after-use

Cumulative Impact

1.6.20 There are existing mineral workings in the area and have been for a significant number of years .

ASSESSMENT (--)Impacts from past and existing mineral workings

Airport Safeguarding

1.6.21 We have established in consultation with East Midlands Airport the degree to which the suggested sites pose a potential risk to aircraft safety, taking into account how the airport operates. The site lies on the very edge of the 13 km birdstrike safeguarding zone around East Midlands Airport, however, it lies almost directly in line with the approach track flown by easterly arriving aircraft. As arriving aircraft fly slowly and descend gradually, they would be at relatively low altitudes at this distance from the airport. In view of this, East Midlands Airport considers this site to be within an area where there is a high potential risk of birdstrike.

Assessment (--) Site lies within an area where there is a high potential risk of birdstrike

SOCIAL TOTAL 11/29

ENVIRONMENTAL CONSIDERATIONS

Water Environment

1.6.22 The site is situated on a Minor Aquifer but is not within a Groundwater Source Protection Zone. Given that the site is located adjacent or near to water course or other surrounding water features, i.e. the River Trent, it would require dewatering. A detailed EIA would be required detailing the effects of this de-watering on the surrounding water environment and what mitigation measures, if any, are required to deal with any adverse impacts. Correct pollution prevention procedures would need to be followed to prevent contamination of groundwater and the surrounding water environment.

1.6.23 The site lies within the floodplain of the Trent, in a Flood Zone 3 where there is a high risk of flooding and therefore a flood risk assessment would be required by the EA. The assessment would need to cover as a minimum:

  • That the physical integrity of any watercourses will be safeguarded by allowing adequate margins between the banks of the watercourse and excavation unless circumstances allow for the 'stand-off strip' to be worked
  • That the effectiveness of local land drainage systems will be preserved
  • That the functioning of the natural floodplain will be preserved

Water Environment - Flooding

1.6.24 The site lies within the Trent floodplain within flood zone 3 where there is a high risk of flooding. A Flood Risk Assessment is required for this site.

ASSESSMENT (--)The site lies within flood zone 3 where there is a high probability of flooding.

Water Environment - Groundwater

1.6.25 The site lies outside a groundwater protection zone.

ASSESSMENT (+) The site lies outside a groundwater protection zone.

Water Environment - Aquifer

1.6.26 Site lies on a minor Aquifer

ASSESSMENT (-) Site lies on a minor Aquifer.

 

Ecology

Presence or absence of existing impacts from mineral extraction

1.6.27 None

ASSESSMENT (--) None, or insignificant, impacts from mineral extraction on habitats within or adjacent to the site

Presence or absence of priority habitats and species

1.6.28 Old Trent Water (candidate WS) is major priority feature cutting across site, dividing arable from improved pasture. Field boundaries generally intact; contain scattered oak and ash. Valuable wet woodland WS in east.

ASSESSMENT (--) Extensive positive ecological value including UK priority habitats and species which should be considered for protection/conservation.

Ecological coherence: Natural Areas, Wildlife Corridors/Linkages

1.6.29 Western half has strong coherence internally and with fields to west and links to river. In east coherence with river is limited.

ASSESSMENT (--)The proposed site accords with the established habitats over a wider area and habitat pattern is strong

Habitat Creation

1.6.30 Existing habitats are intact and make a strong contribution to biodiversity priorities in the west of the site. There is limited requirement for biodiversity enhancement within the site.

ASSESSMENT (--)Existing habitats are intact and make a strong contribution to priority biodiversity targets for conservation and there is strong ecological coherence within the site; habitat creation would not enhance the site or the wider area

Landscape and Visual Impact Assessment

Existing Impacts from mineral extraction

1.6.31 The proposed site is located in the strategic eastern area of the river valleys. Locally, there are insignificant impacts associated with previous mineral extraction.

ASSESSMENT (--) There are insignificant impacts associated with past mineral working

Existing Infrastructure

1.6.32 There is no existing infrastructure associated with this site or within the immediate locality. The infrastructure for this site would need to be developed.

ASSESSMENT (--) There is no existing infrastructure and this will need to be developed for the proposed site to be operated

Strength of Landscape Character

1.6.33 The area of the site north and west of the Old Trent Water and immediately adjacent to the River Trent accords strongly with the established landscape character of the Riverside Meadows LCT. Although there are large arable fields associated with land around the former Meadows Farm the overall character of this site is strong and visually coherent. Field boundaries are generally intact; contain scattered oak and ash and broadly accord with the boundaries shown on 1st edition OS maps. The overall condition of the site is good. There are extensive archaeological features associated with palaeochannels and localised ridge and furrow.

ASSESSMENT (--)The proposed site accords with the established landscape character and is in good condition (Conserve)

Visual Impact

1.6.34 The site is visible from a number of locations around the site. The western and northern parts are visible from residential properties at Willington and Repton School and grounds. Potentially, the north-eastern area is visible from across the River Trent at Twyford. There are two footpaths that pass through the site, including a route adjacent to the Old Trent Water. Overall, this site is considered to be visually sensitive.

ASSESSMENT (--) The site has many visual receptors and/or large parts (or more than one part) of the site will be visible

Historic Environment

Designated sites & settings

1.6.35 Need to consider the setting of the Repton conservation area and listed buildings.

ASSESSMENT (-)Impact on a Grade II designation, conservation area and/or its setting

Archaeological Environment

1.6.36 Isolated areas of ridge and furrow and the SMR site 'the Buries'. Extensive palaeochannels to the south of the river and includes Old Trent Water, a former channel of the River Trent.

ASSESSMENT(--)Extensive, visible and interpretable earthworks and/or known archaeology with high potential for buried remains.

Historic Landscape Character

1.6.37 Many of the field boundaries are visible on 1769 and 1829 maps.

ASSESSMENT(--)Evidence of multi period landscape and/or intact field pattern (as indicated by 1st edition OS or earlier)

Best and most versatile agricultural land

1.6.38 According to DEFRA's Predictive Agricultural Land Classification Map the majority of the site lies in an area where less than 20% is likely to be bmv.

ASSESSMENT(++)Low areas where less than 20% of the land is likely to be bmv)
