JU095/Reports/R004 Borrow Pit Report B02 1

1.0 INTRODUCTION

1.1 Project Summary

1.1.1 Donaldson Associates Limited (DAL) was commissioned by Coronation Power Ltd

to undertake a borrow pit study for the proposed Rooley Moor Wind Farm

development in Lancashire.

1.1.2 The scheme is currently at concept design stage.

1.1.3 The proposed wind farm comprises 12No. turbines with a combined capacity of up

to approximately 39.6MW, access tracks, a sub-station building, and a permanent

anemometry mast.

1.1.4 Having estimated the amount of required crushed stone for the construction of the

development on site, borrow pits can be designed to produce the required stone

volume without the need to import stone from off-site sources, thus reducing

construction traffic volume.

1.1.5 The crushed stone requirement calculated is based on a conceptual track design

and wind farm layout only, which will be subject to change following any layout

revisions and amendments at detailed design stage and following planning

approval. The design has been undertaken without benefit of detailed

topographical survey or ground investigation and is therefore approximate.

1.1.6 This report identifies the proposed borrow pit locations, their anticipated profile and

volume of rock achievable. However this is only a conceptual design and the results

of further detailed topographic and ground investigation surveys will result in the

confirmation of actual rock quality and amendment to the borrow pit profile, to

achieve the required rock volume.

1.1.7 The predominant sandstone bedrock of the site is characteristically interbedded

with less suitable mudstone and thinly laminated siltstone and therefore allowances

have been made in the borrow pit design and volume calculations for the extraction

of surplus material which will not be used in the development.




1.2 Objective

1.2.1 The objective of this report is to identify suitable borrow pit locations and present a

conceptual design of each borrow pit indicating the stone volumes to be extracted

at each location.

1.2.2 Each borrow pit design will present the amount of stone to be obtained but also the

approximate overburden strip required and subsequent restoration profile on

completion of construction.

3.0 SITE LOCATION AND DESCRIPTION

3.1 Site Location and Setting

3.1.1 The site is located approximately 2km northwest of the centre of Rochdale and

approximately 4km south of Bacup and Rawtenstall Lancashire. The site is

elongated in shape following the ridgeline upon which the Rooley Moor Road public

bridleway travels between Rochdale and Rawtenstall, orientated north-northwest

to south-southeast. The site is approximately 4km2 in area and centred on

Ordnance Survey (OS) National Grid Reference (NGR) SD 861 174, with the site

area extending over 4.5km from north to south and over 1.5km west to east at its

maximum extents.

3.1.2 The elevations of the site range from approximately 275m AOD in the far south of

the site to over 470m AOD in the far north, on the flanks of Top of Leach (474m

AOD).

3.1.3 The site is bounded predominantly by adjacent moorland grazing / heath land. The

Naden and Greenbooth Reservoirs lie to the west of the southern half of the site,

with Spring Mill Reservoir to the east. Cowpe Reservoir lies beyond the north-

western site boundary and the operational Scout Moor Wind Farm is located to the

immediate west also.

3.1.3 The majority of the site limits are defined by existing field boundaries and

watercourses with the exception of the central western area and the far northeast.

3.1.4 The active Britannia Quarries lie to the northeast, extracting from the Rough Rock

Sandstone and Haslingden Flags (Millstone Grit Group -see Section 4.1.). A

number of disused quarries lie within the site boundary also which include the

larger Ding Quarry in the northwest of the site, the Bagden Quarry in the central

east area of the site and the Pink Brow and Cat Stones quarries in the south which

all extracted sandstone from the Millstone Grit Group and Coal Measures Group.

3.1.5 Both underground and surface coal mining is known to have been undertaken on

the site with numerous mining features visible on the surface; including disused

mine entries (shafts and adits) and areas of colliery spoil. The previous mining

history of the site is discussed further in Section 4.5.




3.2 Site Reconnaissance

3.2.1 A number of site visits have been undertaken as part of the geotechnical

assessment and conceptual design processes between January and March 2014.

During these walkovers the existing quarry sites and other rock exposures were

examined as well as the recording of additional peat probe data. Possible new

borrow pit locations were explored as well as assessing the possibility of expanding

a number of former, now disused, quarries on site.




4.0 GROUND MODEL

4.1 Solid Geology

4.1.1 Information from the British Geological Survey (BGS) particularly their 2007,

1:10,000 scale map, Sheet SD81NE for Whitworth, confirm that the underlying

geology of the site comprises shallow dipping strata of the Upper Carboniferous

(320-290Ma) Millstone Grit Group; characterised by thick sandstone beds,

interbedded with siltstone, mudstone and rare coal, and the Pennine Lower Coal

Measures Formation (Pennine Coal Measures Group), characterised by

interbedded mudstone, siltstone and sandstone with numerous coal bands.

4.1.2 The Coal Measures strata comprises; exposed from south the north - the Darwen

Flags (fine grained, thinly bedded sandstone), the Milnrow Sandstone (medium

grained, cross bedded sandstone), the Helpet Edge Rock (fine to coarse grained,

cross laminated and thickly bedded sandstone), the Great Arc Sandstone (fine

grained, cross bedded sandstone), Gannister Rock (fine grained, micaceous

sandstone) and the Woodhead Hill Rock (fine to medium grained, medium bedded

sandstone).

4.1.3 The Coal Measures beds dominate the southern half of the site and fault action

has resulted in this succession being exposed again in the most northern part of

the site also, separated by the Millstone Grit (interbedded named sandstone,

siltstone and mudstone), with identified beds of the Rough Rock (coarse grained,

cross bedded sandstone) and the Upper Haslingden Flags (fine grained sandstone

interbedded with sandy siltstone), which is present over the majority of the northern

half of the site.

4.1.4 The bedrock on the site is unknown in terms of its material properties and would

require further assessment of its suitability for use as engineering material at the

site, although the extraction history of the site is a positive indicator. The

interbedded nature of the bedrock indicates a variable overall composition and a

significant proportion of this material may not be suitable for a track surfacing

application, for example where thick bands of finer grained mudstone is present.

For the above reasons, a 100% volume increase has been applied to the volume




of stone estimated to be required for the development to that used to calculate the

borrow pit volumes.

4.2 Drift Geology

4.2.1 The BGS identify only limited superficial geology over the site, with peat deposits

being most prominent in the northern half of the site. Glacial till is also identified in

the lower lying areas beyond the southern site boundary.

4.2.2 The peat probe surveys undertaken by SKM and supplemented by DAL’s own

probing during the walkover; presents results which generally collaborate with the

mapped peat deposits, in that the majority of significant peat is confined to the

higher elevations in the north of the site.

4.3 Structural Geology

4.3.1 There are a number of northwest – southeast orientated faults which cross the site

with downthrows to the northeast and southwest. These have resulted in a large

up-thrown area of the older millstone Grit strata being located between the younger

Coal Measures strata in the northern half of the site.

4.3.2 There is also a singular northeast – southwest trending fault, with a south-easterly

down-throw crossing between two larger, northwest – southeast trending faults

near the site’s centre.

4.3.3 The bedrock dips to the south by up to 10 degrees and is sub-horizontal in some

areas.

4.4 Outcrops

4.4.1 There are numerous rock exposures within the site, those of sandstone being more

numerous due to the more massive bedded nature and the resistance to

weathering when compared to mudstone. The bedrock is exposed not only in

previous quarry sites but natural sandstone bedrock exposures have been utilised

along un-surfaced sections on the route of the Rooley Moor Road.




4.5 Extraction History

4.5.1 The site shows significant evidence of stone extraction with quarries of various

scale scattered around the site. There are workings from at least two coal seams

beneath the site with a number of underground coal mine entries and areas of spoil

tipping within the site boundary also. Historically the surrounding area of the site

has been exploited for quarried stone and coal.




5.0 BORROW PITS

5.1 Overview

5.1.1 A significant volume of stone is required for the Development. The geology of the

site indicates that borrow pits proposed for use in the construction of the

Development could potentially be adequate for all potential rock fill required for

access tracks, including their finishing surface, hardstandings and up-fill beneath

turbine bases where required. This will be confirmed following (i) ground

investigation of the site and borrow pit locations and, (ii) detailed design of the

project.

5.1.2 The estimated calculations for the rock volume required take into account the main

site access roads, smaller access roads (including those for borrow pit access and

met mast), rock up-fill at gravity turbine foundations, construction and sub-station

compounds and crane hardstandings. The volumes were determined using the

Development layout presented on drawing JU095– 023 (Appendix A) and also

takes into account the stone volume obtained from other necessary excavations,

such as at the construction compound location.

5.1.3 The difference between the density of placed and compacted crushed stone

(20kN/m3) and in situ rock density (approximately 25kN/m3) indicates that there will

be 25% bulking between original rock and placed volume, this would theoretically

reduce the borrow volume to 40,000m3. Due to conceptual nature of the design

and the size of the development it is considered that a more conservative approach

is adopted and therefore, it is assumed that the 50,000m3 is required and when

applying the 100% volume increase to allow for processing losses this equates to

a volume requirement of 100,000m3.

5.1.4 Through site visits and analysing of pre-existing data and documents, including

topography, geology, peat depth and stability, and overall superficial cover;

potential borrow pit locations were determined. Two potential areas of extraction

were investigated with volume calculations and borrow pit sections undertaken for

both locations.

5.1.5 An assumed 0.75m thickness of superficial cover was included in the borrow pit

design, based on site visit records and the peat probing results. The exact volume




and quality of rock available cannot be confirmed until a topographic survey and

ground investigation has taken place.

5.1.6 The borrow pits are designed so their excavation does not adversely affect any

adjacent infrastructure, particularly the stability of Rooley Moor Road and other site

tracks.

5.1.7 During their excavation the disturbance to users of Rooley Moor Road must be

considered and measures implemented to reduce the effect of noise and dust to

those users by way of optimising the extraction methods e.g. mechanical ripping

instead of blasting, the use of silenced vehicles and processing equipment and

constructing earth bunds and / or debris / dust fences.

5.1.8 Measures must be employed to prevent waste material from the borrow pits

entering adjacent watercourses. The borrow pits will be designed with a front wall,

lip or bund on their outer edge to prevent any surface water run-off from the borrow

pit fouling the watercourses.

5.1.9 It is recommended that a suitable drainage scheme, in line with the requirements

set out in the Environmental Statement, is designed and installed for each borrow

pit. Space for a drainage scheme has been accommodated within the designed

borrow pit area (the location of the borrow pit area is shown indicatively as dashed

area on borrow pit drawings in Appendix B), either within the extents or on the

periphery of the excavated pit. It is expected that suitable drainage methods such

as filter strips, swales, filter drains, and settlement ponds, be combined and an

attenuation system provided to manage surface water run-off. This water could

then be discharged under a consented licence following robust settling, clarification

and testing processes.

5.1.10 The borrow pit site area is larger than the borrow pits to facilitate working space

and storage of overburden until it can be used in subsequent borrow pit

reinstatement.

5.1.11 Borrow pits will be reinstated with surplus excavated material to provide a more

aesthetic appearance and prevent any unstable and steep rock faces. Complete

infilling of borrow pits should be undertaken only under controlled conditions as

loose or unstable infill can pose a risk to walkers and animal life. Borrow pit filling




will be controlled and engineered to minimise the risk of future excessive settlement

or instability of the fill.

5.1.12 Excavated peat may be used in borrow pit restoration, dependent on the final

restoration profiles and the ground conditions around each borrow pit location,

which will be confirmed in the peat management plan. The use of unconsolidated

peat will be limited to a maximum depth of 1m which will aid landscaping purposes,

but the final design will also consider the stability of the placed peat to ensure there

are no residual risks resulting from peat slides.

5.1.13 The following sections describe each proposed borrow pit in turn.

5.2 Borrow Pit 1

5.2.1 Overview

5.2.1.1 Borrow Pit 1 is located in the south of the site, close to the entrance, on the eastern

flank of Rooley Moor Road, approximately 9m from the road edge. The proposed

borrow pit location is an extension of the former Cat Stones Quarry and lies

immediately adjacent to the main site access track (along Rooley Moor Road)

allowing simple access (See drawing JU095 – 021, Appendix B).

5.2.2 Geology

5.2.2.1 The potential borrow pit location geology comprises fine to coarse grained, cross

laminated to thickly bedded sandstone of the Helpet Edge Rock formation.

5.2.3 Hydrology

5.2.3.1 The proposed borrow pit lies approximately 0.7km west of the Spring Mill Reservoir

and 0.8m northwest of the smaller Prickshaw Reservoir. Small un-named

watercourses feed directly to these water-bodies from an area immediately

adjacent to the proposed borrow pit site. Specific drainage measures will have to

be employed to retain any borrow pit waste to within the consented borrow pit

boundary.




5.2.4 Peat / Superficial Cover

5.2.4.1 The results of the peat probing survey in this area indicates that the peat and

superficial cover in this location appears to be less than 0.50m. However isolated

deeper pockets of peat may still be present and there is also the chance of

disturbed bedrock and overburden material being present as a remnant of the

previous quarry workings. An assumed overall superficial material cover and likely

zone of weathered bedrock near the surface of 0.75m thickness in total has been

adopted in the borrow pit design and volume calculations.

5.2.5 Topography

5.2.5.1 Topography in this area provides natural cover to reduce effects on residential

properties and primary landscape and visual viewpoints to the north. south and

west. Although likely to be visible from this direction, there is a separation of the

borrow pit from properties to the east of approximately 1km.

5.2.6 Summary

5.2.6.1 The location should be capable of a borrow pit producing up to 40,000m³ of rock;

this could be achieved by a 250 by 68m excavation (average dimensions) with a

typical maximum excavation depth of 3.5m. Effects on residential properties would

be negligible due to separation distance and natural topographic cover. The

formation of the borrow pit would be integrated into the development of the main

access track. Overburden stripped from the area of the borrow pit excavation will

be temporarily stored adjacent to the borrow pit or at a designated temporary

storage area before being used in reinstatement of the borrow pit.

5.3 Borrow Pit 2

5.3.1 Overview

5.3.1.1 Borrow Pit 2 is located along a proposed temporary section of access track on the

eastern side of Rooley Moor Road (approximately 300m east of Rooley Moor

Road), in the centre of the site, between Bagden Hillocks and the disused Bagden

Quarry to the east. The proposed borrow pit location lies immediately adjacent to




the temporary access track, approximately 10m away, allowing simple access (See

drawing JU095 – 022, Appendix B).

5.3.2 Geology

5.3.2.1 The geology at the potential borrow pit location comprises Millstone Grit lithology

(interbedded sandstone, siltstone and mudstone) as well identified beds of the

Rough Rock Sandstone (coarse grained sandstone) and the Upper Haslingden

Flags (fine grained sandstone interbedded with siltstone). The strata of the borrow

pit area dip gently ( approx. 3 degrees) to the southeast. The northeast – southwest

trending fault described in Section 4.3 lies at the north-western corner of the

proposed borrow pit and the borrow pit’s proximity to the fault may reveal the fault

fracture zone on excavation.

5.3.3 Hydrology

5.3.3.1 A number of small un-named minor watercourses lie to the east and south east of

the proposed borrow pit location, which eventually converge in Fern Isle Brook

which flows into Prickshaw Brook before this watercourse flows into Spring Mill

Reservoir to the southeast. Specific drainage measures will have to be employed

to retain any borrow pit waste to within the consented borrow pit boundary to avoid

waste and debris flowing down slope into the sensitive watercourse.

5.3.4 Peat / Superficial Cover

5.3.4.1 The results of the peat probing survey in this area indicates that the peat and

superficial cover in this location appears to be less than 0.5m. However isolated

deeper pockets of peat may still be present and there is also the chance of

disturbed bedrock and overburden material being present as a remnant of the

previous quarry workings. An assumed overall superficial material cover and likely

zone of weathered bedrock near the surface of 0.75m thickness in total has been

adopted in the borrow pit design and volume calculations.

5.3.5 Topography

5.3.5.1 Topography in this area provides natural cover to reduce effects on residential

properties and primary landscape and visual viewpoints to the north, west and




south. Although likely to be visible from this direction, there is a separation of the

borrow pit from properties to the southeast of approximately 1km.

5.3.6 Summary

5.3.6.1 The location should be capable of a borrow pit producing up to 60,000m³ of rock;

this could be achieved by a 137 x 105m benched excavation (average dimensions)

with a typical maximum excavation depth of just over 7m. Due to the size of the

excavation and the topography, the excavation will be benched with two levels to

achieve the required volume of stone without one excessively deep face. Effects

on residential properties would be negligible due to separation distance and natural

topographic cover. The formation of the borrow pit would be integrated into the

development of the main access road. Overburden stripped from the area of the

borrow pit excavation will be temporarily stored adjacent to the borrow pit, before

being used in the borrow pit reinstatement.




6.0 CONCLUSIONS & RECOMMENDATIONS

6.1 Conclusions

6.1.1 Published sources and the site walkover confirm that the majority of the site and

the location of each of the borrow pits is underlain by the Upper Carboniferous

Millstone Grit Group and the Pennine Coal Measures Group, characterised by

interbedded sandstone, siltstone, mudstone and coal seams. The bedrock geology

at each borrow pit site is overlain by a mixture of peat, residual soil and weathered

bedrock.

6.1.2 Varying depths of peat and peaty soil deposits are present over the site, with some

isolated areas having depths greater than 2m.

6.1.3 The bedrock on the site is unknown in its definitive quantity and properties;

however; visual examination on site of available exposures and the extraction

history of the site indicates that the majority of the bedrock may be of suitable

quality for use as engineering fill on the wind farm development and for use in site

track construction.

6.1.4 There may be significant bands or beds of unsuitable finer grained mudstone or

shale, interbedded with the more favoured medium to thickly bedded sandstone

and for this reason a generous 100% volume increase has been applied to the

volume of stone estimated to be required for the development to that used to

calculate the borrow pit volumes. Until a ground investigation and topographic

survey is complete there are risks associates with stone quality and available

volume.

6.1.5 An estimated 21,600m3 of unsuitable overburden, including peat, will be produced

in the development of the borrow pits. This overburden will be temporarily stored

on site adjacent to the borrow pits prior to its use in the restoration of the borrow

pits on completion of construction.




6.2 Recommendations

6.2.1 It is recommended that a comprehensive ground investigation is undertaken prior

to development to confirm the ground conditions over the site, including the nature

and thickness of the superficial cover along with the weathering state and strength

of the bedrock for both foundation assessment and borrow pit suitability.

6.2.2 A detailed topographic survey of the proposed infrastructure locations, including

the borrow pit sites will complement the detailed topographic survey of the track

layout already obtained. The detailed design of the borrow pits can then be

undertaken following detailed cut and fill design, which will provide the actual stone

volumes required for the development.

6.2.3 The achievable rock volumes from each borrow pit can then be confirmed. Until a

detailed design of earthworks and site infrastructure is undertaken, there are risks

associated with required stone quantity.

6.2.4 Consideration must be given at detailed design stage and within the construction

stage method statements to the stability of the borrow pits and the overburden

storage areas with regard to bedrock, slope and peat stability. Management of the

excavations and placement of material must be undertaken and some temporary

works may be required prior to use and a safe working distance from the Rooley

Moor Road maintained at all times.
