INTRODUCTION
1.1
General
Mick George Ltd. (Mick George) proposes to extract limestone at its Ringstead Grange site and
restore the exhausted workings using imported inert fill materials. DAB Geotechnics was
appointed by Mick George to undertake a hydrological and hydrogeological assessment of the
proposed quarry. The study has entailed:
1.2
(i)
the provision of a Landmark, ‘Envirocheck’, report to determine the location of all
licensed surface and groundwater abstractions, discharge consents, landfill sites and
pollution incidents at distances of up to 2km from the centre of the site (Appendix A);
(ii)
liaison with East Northamptonshire Council with regard to the location of any unlicensed
(private) water supplies within at least 1km of the site (Appendix B);
(iii)
reference to the scoping opinion provided by the Environment Agency in its letter to
Northamptonshire County Council dated 8th November 2011 (ref. no.
AN/2011/113241/01-L02), a copy of which is presented in Appendix C.
(iv)
an examination of the geological maps and reports published by the British Geological
Survey (BGS) and the provision of an Envirocheck report based on 1/10,000 scale digital
information (Appendix D);
(v)
reference to a number of relevant borehole logs held on the BGS GeoRecords archive
(Appendix E);
(vi)
the acquisition of an Envirocheck mining and ground stability report (Appendix F);
(vii)
an examination of the most recent aerial photographs;
(viii)
the compilation of a flood risk assessment in accordance with the National Planning
Policy Framework (Department for Communities and Local Government, 2012a)
(Appendix G); and
(ix)
an assessment of the possible effects on surface and groundwater resources and the
mitigation measures that will be undertaken.
Location
The proposed development is located about 1.5km south-west of Ringstead and 2km north-west
of Raunds in an area administered by East Northamptonshire and Northamptonshire County
Councils (Figure 1). The site comprises arable agricultural land and is bounded along its southeastern margin by a wooded valley that lies adjacent to the A45 public road. Access to the quarry
will be gained from the B663 (Raunds or London Road) located to the north-east. The Grid
Reference for the centre of the site has been taken as 498050 273900 (1/50,000 scale Ordnance
Survey Map Sheet 141 Kettering, Corby & Surrounding Area). An aerial photograph is presented
as Figure 2.

DABGeot/11093/Final
1.3
Topography
The site occupies an area of 64.3 hectares and is located in an area of gently undulating land.
Surface elevations range from about 66m above Ordnance Datum (AOD) in the east to 53m AOD
in the west and fall towards the north-west, west and south-west.
1.4
Development Proposal
Details of the proposed working scheme for the quarry are contained within the Environmental
Statement and are shown on the Working Scheme Plan (Dwg. No. R15/03) and the Indicative
Phasing Plans (Dwg. Nos. R15/05). The quarry excavations will cover an area of about 52
hectares and will be worked in a south-westerly and then north-easterly direction along a
succession of NW-SE aligned cuts or development phases. The quarry excavations will reach a
maximum of about 12m below ground level.
The soils will be stripped in a progressive fashion. The initial volumes will be temporarily stored,
but the remainder will be placed directly to bed as the exhausted workings are backfilled to
restoration level using overburden, quarry discard and imported inert materials. The existing
topography and landform will be largely replicated.
The development has been designed to minimize the area of disturbance at each stage of the
development with land either remaining in agricultural production or restored for that use.
Surface runoff will be further attenuated by creating a number of wetland areas of ecological
interest (Conceptual Restoration Plan, Dwg. No. R15/14).
Surface runoff from the working areas and any groundwater abstracted from the excavations will
be pumped and drained to settlement lagoons. The treated water will be discharged into an
unnamed tributary of Hog Dyke, subject to the consent of the Environment Agency. Surface
runoff from the restored areas that will be created in the northern part of the site will be drained
to newly created wetland areas and to the existing agricultural drainage system. Measures will be
taken to alleviate a problem of minor flooding of Station Road adjacent to the cemetery.

GEOLOGY
2.1
Published Information
The geology of the quarry area has been determined by reference to the following maps and
reports that have been published by the British Geological Survey (BGS):
1/50,000 scale Geological Map, Sheet 186 Bedrock and Superficial Deposits Edition (2006);
‘Geology of the Wellingborough District’ (Barron et al., 2006); and
1/10,000 scale digital maps presented in Appendix D.
2.2
Exploratory Drilling
Details of 10 exploratory boreholes, some of which provide details of the groundwater
conditions, have been obtained from the BGS GeoRecords website. Copies of the borehole logs
are provided in Appendix E and their locations are shown on Figure 3.
A total of 20 boreholes (nos. 1-20) were first drilled on the site by the landowner, Foster Farms
Ltd. in October 1988. These were extended to a maximum depth of 8.2m using a tractor mounted
rotary blasthole rig. Eight rotary cored and flight augered boreholes were then drilled on the site
by Amey Roadstone Corporation in December 1988 and January 1989 (nos. ARC1-8). A
reconnaissance borehole investigation was carried out by Steetley Quarry Products Ltd. in May
1989, when 2 cored boreholes (nos. RC89/1-2) and 11 openholes (nos. RO89/3-13) were drilled.
A more detailed drilling programme comprising 3 cored boreholes and 23 openholes was
undertaken in January 1990 (nos. RG90/1-3 & R90/1-23 respectively). Finally, a site
investigation comprising nine boreholes (nos. MG1-9) was completed by Mick George in 2011.
Four of these boreholes have been instrumented to allow groundwater monitoring. The borehole
locations are shown in Figure 4.
The exploratory boreholes show that the lateral extent of some of the bedrock strata differs from
that shown on the BGS maps.
2.3
General Succession
2.3.1
2.3.1.1 Recent (Flandrian) Alluvium
Recent deposits of alluvium are present along the course of the River Nene, Hog Dyke and their
tributaries (1/10,000 scale Superficial Geology map, Appendix D). These generally comprise
sand, silt and clay and reach up to 4m in thickness.
2.3.1.2 River Terrace Deposits
Deposits of sand and gravel along the valley of the River Nene are regarded as river terrace
deposits. A simple classification based on mapped units at separate elevations has now been
abandoned, as it is now believed that their deposition is multi-phase.
3
DABGeot/11093/Final
The Nene Valley Formation encompasses three river deposits of which only two have been
identified in the area of interest. The Ecton Member or, ‘first terrace’, extends about 2m above
the present floodplain and is overlain by recent alluvium. The gravel fraction comprises about
32% flint, 28% quartzite, 38.5 % local ironstone, sandstone and limestone and 1.5% chalk. The
deposits reach a maximum thickness of about 4.5m.
The Grendon Member or, ‘second terrace’, is much more restricted in extent. Its surface lies
between 5 and 9m above the present floodplain. The deposits reach a maximum thickness of 7.6m
and have a similar composition to the Ecton Member.
The 1/10,000 scale Superficial Geology map in Appendix D shows that sand and gravel of the
Ecton Member are present to the north-west of Ringstead Grange Farm and some distance to the
south of the site. The deposits have been exploited and flooded workings extend to the west of
Ringstead village (Figure 1).
2.3.1.3 Glacial Till and Glacio-Fluvial Sand and Gravel
Two glacial tills have been mapped in the Ringstead area: an upper till that is correlated with the
Oadby Till and a lower one named the Bozeat Till. The relationship between these strata is
uncertain as no intervening organic deposits have yet been recorded. They may represent deposits
of discrete glacial events or merely different facies of the Oadby Till.
The Bozeat Till is a dark bluish grey diamicton consisting of sandy, silty clay with clasts of
mainly Jurassic limestone and ironstone, some quartz and quartzite, rare flint and chalk. A
maximum thickness of 5m has been recorded that always underlies the Oadby Till. The latter
closely resembles the, ‘Chalky Boulder Clay’, of central and south-east England. It commonly
reaches up to 15m in thickness. It is an olive grey to grey diamicton that weathers to yellowish
brown and comprises silty clay with abundant clasts of chalk, flint, Jurassic limestone, sandstone
and ironstone, quartz, quartzite and Carboniferous limestone and sandstone.
Glacio-fluvial sand and gravel occur as sparsely distributed discontinuous bodies resting on,
within and beneath both tills. The clasts comprise Jurassic limestone, sandstone and ironstone,
flint, quartz and quartzite and locally chalk.
The 1/10,000 scale Superficial Geology map in Appendix D shows that Bozeat and Oadby Tills
are present in the eastern part of the site. Deposits of glacio-fluvial sand and gravel are recorded
in its northernmost part.
.
2.3.1.4 Made Ground
The 1/10,000 scale Artificial Ground and Landslip map in Appendix D shows that there are a
number of areas of made ground in the Ringstead area. Those labelled WMGR refer to backfilled
ironstone workings in the Northampton Sand Formation (Section 2.3.2.3), one of which is located
along the northern margin of the site.

Bedrock Strata
2.3.2.1 General
It is proposed to extract limestone from the Cornbrash and Blisworth Limestone Formations. The
limestones form part of a sedimentary succession of Jurassic age, details of which are provided in
Table 1. Fuller descriptions are provided below in ascending order. The 1/10,000 scale Bedrock
and Faults map in Appendix D shows the lateral extent of the various formations.

Table 1 Details of the Stratigraphic Succession at the Proposed Quarry
2.3.2.2 Lias Group
The Whitby Mudstone Formation forms the uppermost part of the Lias Group and comprises a
bluish grey mudstone with thin limestones towards its base. It varies in thickness from 35 to 56m.
2.3.2.3 Inferior Oolite Group
The Inferior Oolite Group is entirely represented in the area by the Northampton Sand Formation.
The constituent sideritic limestone has been widely quarried as a source of building material and
iron ore. The deposit ranges in thickness from 4 to 6m.
2.3.2.4 Great Oolite Group
The Great Oolite Group rests unconformably on the eroded surface of the Northampton Sand or
Whitby Mudstone Formations. The Rutland Formation can reach up to 15m in thickness, but only
3.55 to 4.98m has been proved on the site. The basal Stamford Member comprises a pale to dark
grey and black sandy mudstone with ironstone bands. This is overlain by pale grey fine to
medium grained sandstone. The overlying sediment consists of a rhythmic succession of
mudstones and sandstones, including a calcareous mudstone and limestone horizon known as the
Wellingborough Limestone Member.
5
DABGeot/11093/Final
The Blisworth Limestone Formation was deposited in shallow marine lagoons following
transgression. It is typically 5 to 6m thick and is separated into two members. The Roade Member
consists of interbedded argillaceous, bioclastic packstone, wackestone and lime mudstone. It
measures some 1.8m in thickness. The overlying Irchester Member is dominated by ooidal and
peloidal limestones with interbedded lime mudstone beds.
The overlying Blisworth Clay Formation comprises a smooth plastic mudstone, characteristically
variegated in colour and showing blue green, magenta and purple mottling. It lies unconformably
on the limestone. The irregularly bedded bioclastic packstones and grainstones of the Cornbrash
Formation form the uppermost part of the Great Oolite Group.
2.3.2.5 Ancholme Group
The Kellaways Formation is divided into the basal Kellaways Clay Member, which comprises
dark grey mudstone, and the overlying Kellaways Sand Member. The latter consists of a
sequence of pale grey, fine grained sand or sandstone, siltstone and mudstone. The Oxford Clay
Formation has only been mapped in the easternmost part of the site. Its basal part consists of dark
brownish grey mudstone.

2.4
Geological Structure
The structure of the Jurassic strata at the proposed quarry site generally conforms to the regional
south-south-easterly dip of less than half a degree (1v in 115h). This may be modified by
flexuring or the effects of faulting or superficial structures. A number of minor faults have been
recorded on the site. These trend NW-SE and are shown on the 1/10,000 scale maps which are
presented in Appendix D.
The bedrock strata are dissected by at least two, subvertical joint sets.
2.5
Mining and Ground Stability
2.5.1
General
A mining and ground stability report has been obtained for the site and a copy is provided in
Appendix F.
2.5.2
Mining Stability
There are no records of any underground workings in the Northampton Sand Formation
(ironstone), but backfilled surface excavations are present to the north-west of the site (1/10,000
scale Artificial Ground and Landslip map, Appendix D). Sand and gravel has been extracted
along the valley of the River Nene and the limestone has also been recovered from the Cornbrash
Formation at Scalley Farm Pit, Raunds (Grid Ref. 498939 273551). The exhausted sand and
gravel workings are considered to represent a site of special scientific interest (SSSI) with the
majority classified as a Ramsar site and the remainder as a local nature reserve.
2.5.3
Ground Stability
The BGS National Geoscience Information Service states that there is no potential for
compressible ground stability hazards on the site and that the potential for instability due to
collapsible ground, landslide, ground dissolution and running sand is low to very low. The
potential for compressible ground stability reaches moderate levels in those areas of backfilled
ironstone workings because the backfill was not compacted during its placement. There is,
however, no surface expression of any recent settlement. There is no evidence of significant
karstification of the Cornbrash and Blisworth Limestone Formations, but there remains a
potential for dissolution, more so where they lie close to ground surface. The potential for
shrinking or swelling clay ranges from zero to moderate, dependent upon the sub-surface strata.
The 1/10,000 scale geological maps in Appendix D indicate that the areas of moderate risk are
linked to the outcrop of the Blisworth Clay Formation. The Rutland Formation and the superficial
cover of glacial till form areas of low risk. The 1/50,000 scale map provided in Appendix F
confirms that the potential is low in the area around Ringstead village.

HYDROLOGY
3.1
Rainfall
The long term average annual rainfall at the proposed quarry site is approximately 612mm
(NERC, 1999).
3.2
Catchment and Principal Drainage Paths
The catchment boundaries for the site have been determined using the Flood Estimation
Handbook CD-ROM (NERC, 1999) and are shown in Figure 5. The catchment characteristics are
provided in Table 3. Surface runoff is ultimately directed to an unnamed ephemeral stream
located along the south-eastern boundary of the site. This flows in a south-westerly direction and
joins Hog Dyke before discharging into the River Nene at Grid Ref. 496900 273850. The river
flows in a north-north-easterly direction.

3.3
Site Specific Drainage Details
The site presently comprises arable land and it is assumed that a network of agricultural tile
drains has been installed. There are no plans of the drainage system, but the site was inspected on
the 8th December 2011 and a number of open ditches recorded, details of which are shown on
Figure 6. Attention is also drawn to Photographs P1 to P5. There is no evidence to suggest the
development of karstic features in the Cornbrash and Blisworth Limestone Formations. A number
of flooded sand and gravel workings are present to the north of Ringstead Grange Farm along the
Nene valley.
3.4
Flood Risk
Extracts of the Environment Agency Flood Map, which are presented in Appendix A, indicate
that the proposed Ringstead Grange site lies in Flood Zone 1 having less than 1 in a 1,000 year
annual probability of flooding (i.e. <0.1%). A flood risk assessment has been carried out in
accordance with the National Planning Policy Framework (Department for Communities and
Local Government, 2012a) using the advice given in the Technical Guidance (Department for
Communities and Local Government, 2012b) and the notes provided for the former Planning
Policy Statement (PPS) 25 ‘Development and Flood Risk’ (Department for Communities and
Local Government, 2009). Details are provided in Appendix G. The assessment concludes,
amongst other things, that the development will not increase the risk of downstream flooding.
3.5
Greenfield Runoff Rate
The greenfield runoff rate for the site has been determined using the methodology described in
the Institute of Hydrology Report No. 124 (NERC, 1994). The calculations are as follows and are
presented in Table 4.
Area: 64.3 hectares or 0.643 km2
Average Annual Rainfall for quarry: 612mm.

The website also indicates that the ecological and chemical quality of the river is classified as
moderate and good respectively at Grid Ref. 497414 275188. However, the ammonia, copper,
iron and zinc concentrations are presently considered to be high. The same comments are made
with regard to Hog Dyke.
There are records of only one pollution incident to surface waters in the search area (13th August
1992, no. 1442). These refer to the Hog Dyke at Grid Ref. 497400 273500. The source of the
pollution was not found, but the incident was considered to be significant (Category 2). The

The mapped locations of these strata are shown in Appendices A and D. There are no source
protection zones on the site or within 1km of its boundary.
4.2
Hydraulic Properties of Strata
4.2.1
The deposits of glacial till will have a very low hydraulic conductivity, typically less than 10 -9
m/s, and where present this will greatly inhibit the infiltration of the underlying bedrock. The
conductivity of the glacio-fluvial deposits will be much higher, possibly falling within the range
10-3 to 10-5 m/s, and as such will allow greater infiltration.
4.2.2
Bedrock Strata
Groundwater flow in the bedrock strata will be largely confined to natural joints and fissures,
most especially in the limestones. There is no evidence of significant karstification, although it is
entirely possible that some dissolution has occurred along the joint planes. Nevertheless, the mass
permeability could be of the order of 10-6 m/s. It is expected that Blisworth Limestone and
Cornbrash Formations will be largely confined by the underlying and overlying deposits of
mudstone.

Table 11 Groundwater Analysis Results
16
DABGeot/11093/Final
All four monitoring installations are standpipes that record the groundwater conditions within the
succession extending above the Whitby Mudstone Formation. It can be deduced from the
recorded levels that there is relatively little water present and that consequently inflow rates into
the excavations will be very low.
4.4
Groundwater Quality
The Landmark Envirocheck report (Appendix A) does not provide any details of groundwater
quality, but the Environment Agency’s website confirms that the current quantitative and
chemical quality in the Northampton Sands and, ‘Lower Jurassic Unit’, is good at Grid Refs.
497213 273484 and 499118 272309. There are no recorded groundwater pollution incidents.
Groundwater samples have been taken from the monitoring installations and the analysis results
are presented in Table 11. The following observations can be made:
(i)
the pH levels reflect neutral conditions;
(ii)
conductivity ranges from 780 to 1900 S/cm indicating low to moderate levels of solute
concentration;
(iii)
heavy metal concentrations are generally quite low, in particular the red list substances
cadmium and mercury;
(iv)
chloride concentrations are low; and
(v)
sulphate concentrations are variable and the majority exceed the drinking water standard.
The analysis results represent the, ‘average’, chemical composition for the groundwater present in
the bedrock succession. Some of the marine mudstones, such as those of the Whitby Mudstone
Formation, contain iron pyrites which weather to form sulphate. Any localised acidity is
adequately buffered by the dissolved calcium carbonate and bicarbonate derived from the
limestones.
4.5
Licensed and Unlicensed Groundwater Abstractions
The Landmark Envirocheck report (Appendix A) indicates that there are four licensed
groundwater abstractions within the search area, two of which have been revoked. The status of
one of the remaining abstractions is not known, but both lie some distance from the site. A
summary of the details is provided in Table 12.
East Northamptonshire Council has confirmed that there are no unlicensed (private) groundwater
abstractions within at least 1km of the site boundary (Appendix B).

Waste Handling, Disposal and Treatment Sites and Waste Transfer Stations
There are no registered or historic landfill sites, waste handling or treatment sites, or waste
transfer stations within the Landmark Envirocheck search area. The Environment Agency’s
website provides details of a number of historic landfill sites, but the closest are located some 2 to
2.5km to the north and north-east of the proposed development.
Gas monitoring has been carried out on the site and the results are presented in Table 13. Very
little or no methane has been encountered in the absence of any putrescible material. The
presence of carbon dioxide and the slight depletion of oxygen concentrations are thought to
reflect anaerobic bacterial activity in the soils and weathered bedrock.

PREDICTED EFFECTS OF PROPOSED QUARRY DEVELOPMENT AND
MITIGATION MEASURES
5.1
Management of Water on the Proposed Quarry Site
The development has been designed so that a large part of the site will remain undisturbed and in
agricultural production or in a state of restoration at any one time. It is proposed to manage
surface runoff and groundwater using a system of cut-off ditches, drainage channels and
temporary sumps. The water will be pumped and/or drained to treatment areas that will comprise
settlement ponds with storm water storage capacity, some of which will be permanently
established in the southern part of the site. Additional storage will be provided in the excavations
and in the drainage channels. The treated water will be discharged into the unnamed tributary of
Hog Dyke as shown on the Working Scheme Plan (Dwg. No. R15/03). An environmental permit
(discharge consent) will be sought from the Environment Agency. The southern lagoons will
form a permanent feature of the restored site. It is also proposed to drain water from the northern
part of the site following its restoration to agricultural land. Wetland areas will be established to
create additional retention with the aim of resolving the present problem of flooding on Station
Road at the point shown on Figure 6.
5.2
Groundwater Resources
5.2.1
Estimated Groundwater Inflow Rates
The site will be developed in a progressive manner with the excavations formed along a
succession of cuts. These are shown on the Working Scheme Plan (Dwg. No. R15/03) as Phases 1
to 23 and be backfilled as the limestone is extracted. The operator will aim to minimise the area
of disturbed ground and hence the size of the excavation void at any one time.
The borehole monitoring installations (Table 10) suggest that very little groundwater will be
encountered in the quarry excavations. This will be largely confined within the Blisworth
Limestone Formation, the base of which will form the quarry floor, but there is likely to be some
leakiness owing the presence of natural joints and fissures. For the purposes of this exercise, it
has been assumed that the saturated thickness is 2.20m, just under half that of the limestone. This
is a conservative assumption and the formation may well prove to be largely dewatered.
Groundwater inflow will extend from all four excavated slopes of the initial boxcut and
subsequently from a combination of in situ bedrock and inert fill that will be placed in the
exhausted workings. The backfill will comprise a mixture of overburden and imported material,
some of which will be cohesive in nature.
Reference has been made to Science Report SC040020/SR1 (Environment Agency, 2007) to
estimate the inflow rates. The lateral extent of the drawdown will vary dependent on the length of
time that transpires as each excavation cut is formed and the rate of recovery where the workings
have been backfilled. The Working Scheme Plan (Dwg. No. R15/03), which forms part of the
planning submission, shows that the cut lengths will vary from about 295 to 530m. The initial
boxcut in the north-eastern part of the site will measure some 382m in length and 100m in width.
Thereafter, the majority of the excavation cuts are 50 to 60m wide.
19
DABGeot/11093/Final
If it is assumed that the groundwater flow in the Blisworth Limestone is confined, the inflow rate
per linear metre of excavation (Q) can be estimated using the Thiem equation for steady state
conditions:
Q = 2KD(s1 – s2)/2.30log(r2/r1),
where K is the hydraulic conductivity, D is the saturated thickness of the aquifer, s 1 and s2
represent the drawdown in two observation boreholes and r2 and r1 are the distances or radii
extending from an abstraction well.
If there is only one observation point and the water is drawn from an excavation, the equation
becomes:
Q = 2D(se)/2.30log(Ro/re)
where se is the drawdown in the excavation, re is the effective radius of the excavation and Ro is
the radius of influence equivalent to the distance at which there is no drawdown (i.e. s2 is zero).
The equivalent radius (re) can be estimated using the equation for a rectangular excavation
provided by Powrie and Preene (1992):
re = (a + b)/
There are independent methods of estimating the value of Ro. Sichardt’s equation has been used
and whilst this grossly under-estimates its value it does give a conservative inflow rate from
which adequate pumping capacity can be determined. The use of this equation is, however, not
encouraged by the Environment Agency. Fortunately, the maximum value of Ro can be estimated
at Ringstead Grange because the limestone outcrops beneath the soil and glacial cover in
relatively close proximity (1/10,000 scale geological maps in Appendix D). The exploratory
boreholes suggest that it lies even closer. Nevertheless, a range of Ro values has been used
equivalent to re plus 50, 100, 200 and 300m. (Note. These are measured from the centre of the
excavation as is re.) The drawdown (se) has been taken as 2.20m.
The hydraulic conductivity of the limestone has been taken as 10-6 m/s to reflect the lithostatic
unloading that will occur during the quarrying process and some measure of dissolution along the
natural joints. The conductivity of the backfill will vary considerably. Initially, it could be as high
as 10-3 m/s, but it will become less permeable as it is surcharged by additional volumes of
material, probably falling to 10-5 m/s about one or two cut widths back from the excavation void.
Backfilling will be progressive, but the calculations have been based on two cut widths for those
excavations extended beyond the boxcut (i.e. Phase 1). An additional allowance has also been
made for flow along the loosewall (a factor of ten times higher per linear metre). The calculation
results are presented in Table 14. Faulting is known to be present on the site and although this
might compartmentalise the groundwater, its effect has been ignored.
20
DABGeot/11093/Final
The estimated inflow rates are low showing little change beyond a distance of about 400 to 500m
from the centre of the excavations. Flow rates through the quarry floor will be insignificant. This
will comprise mudstone strata of the Rutland Formation. Experience has shown that by far the
majority of the water that will be drawn from the excavations will be surface runoff. This will
serve to dilute the solute concentrations detailed in Table 11.

5.2.2
Effect of Drawdown
The calculation results shown in Table 14 are based on a saturated thickness of 2.20m in the
Blisworth Limestone. This is a conservative assumption and it is thought that very little
groundwater will be encountered. Any drawdown will be very restricted in lateral extent and will
be further confined by the outcrop of the limestone. Table 12 provides details of two licensed
groundwater abstractions that are presently active. Both lie at some considerable distance from
the centre of the site where they are unlikely to be derogated by any drawdown in the Blisworth
Limestone Formation or the overlying strata. There are no private or unlicensed abstractions
within 1km of the site boundary (Appendix B).
21
DABGeot/11093/Final
The groundwater monitoring installations point to the complete absence of high piezometric
pressures in the bedrock and it can be concluded that the topsoil and subsoil are subsoil are most
likely under-drained in the Ringstead Grange area. Consequently, it is not thought that any
drawdown in the Blisworth Limestone Formation will have an adverse effect on surface
vegetation and agricultural yields. There will be no adverse effect on the abandoned sand and
gravel workings that lie some distance to the north-west and south-west of the site. These have
been identified as important areas of ecological interest (i.e. SSSI and Ramsar status).
5.2.3
Shrinkage of Bedrock Strata
Concern has been expressed that the dewatering operations at the quarry will lead to shrinkage of
the mudstones that underlie Ringstead village and other buildings in the area. Shrinkage could
damage the foundations and give rise to cracking and structural damage (BRE, 1990a, 1990b,
1993 and 1997; Bonshor and Bonshor, 1997). Some of the mudstones in the Jurassic strata do
contain clays of montmorillonitic or mixed layer type and as such will swell and shrink with
changes in moisture content. These changes can be brought about by the growth or removal of
trees.
The mining and ground stability report in Appendix F indicates that the potential for swelling
and shrinkage around Ringstead village is low regardless of the very limited extent of any
drawdown around the proposed quarry excavations. Any dewatering will only affect the
Blisworth Limestone Formation and the overlying strata. For this reason, the nearest building
structures at Ringstead Grange Farm will not be placed at risk. Top Lodge is unoccupied and
derelict.
5.2.4
Settlement of Backfill
The backfill materials will be tipped, spread and trafficked by the earthmoving plant deployed at
the quarry, but it is not planned to undertake systematic compaction. Self-weight compaction and
consolidation will occur as the height of the fill is raised. There will be some creep settlement
which can be expressed as follows:
Ds = αHlog10(t2/t1)
Sowers et al. (1965)
where Ds is the vertical strain or settlement, α is the creep compression parameter and t1 and t2 are
measured times after placement.
The creep compression parameter will probably equate to approximately 0.5% at the Ringstead
Grange site, within the range 0.2% for fully compacted rockfill to 1% for loose tipped mudstone.
This will equate to a maximum of 0.06m in the period 1 to 10 years after placement where the fill
reaches a maximum of 12m in thickness. The majority of the settlement will occur during and
shortly after placement (i.e. during the operational period of the quarry). A further 0.06m may
then occur within the period 10 to 100 years. The loose tipped material in the former ironstone
workings to the north of the site shows very little evidence of settlement.
22
DABGeot/11093/Final
Collapse settlement will also occur in the fill due to the infiltration of surface water and the
recovery of groundwater. The scale of this settlement will depend on the degree of compaction
achieved during the placement of the fill, but is expected to be of the order of a few millimetres.
The restoration drainage system will be designed to cater for the likely settlement that will occur
in the fill. Particular attention will be paid to those areas where the differential settlement is likely
to be greatest (e.g. buried excavation slopes). Provision will also be made to cater for the possible
increased levels of rainfall that might occur as a consequence of climate change.
5.2.5
Groundwater Quality
There are no known waste handling or treatment sites, or waste transfer stations within at least
1km of the centre of the proposed extension site. These might otherwise represent potential
sources of groundwater contamination. The analysis results presented in Table 11 give some
impression as to the quality of the groundwater on the site. Owing to the nature of the monitoring
installations, however, the sampled water may be partly or wholly derived from strata underlying
the Blisworth Limestone Formation.
The exhausted workings will be partly backfilled using overburden and discard materials from
the crushing and screening process. This material will comprise a mixture of clay, mudstone and
some limestone and as such will be pH neutral. It is not expected to have an adverse impact on
groundwater quality. The proposed importation of inert material to complete the backfilling
process will be subject to legislative control. This will also ensure that there is no adverse impact.
5.3
Surface Water Resources
5.3.1
Flood Risk
A Flood Risk Assessment has been carried out in accordance with the National Planning Policy
Framework (Department for Communities and Local Government, 2012a) and a copy is provided
in Appendix G. The assessment has been set out in accordance with the proforma provided by
the Department for Communities and Local Government (2009). The main conclusions of the
assessment are summarized below.
(i)
The site lies in Flood Zone 1 and there will be negligible risk of flooding from streams or
rivers during the extraction, restoration and post-restoration phases.
(ii)
There will be only a very low risk of flooding of the excavations by groundwater.
(iii)
Surface runoff from the site will largely accumulate in the excavations. There is a risk
that during extreme weather conditions the rate of surface runoff will exceed the capacity
of the drainage channels and any pumps that may be deployed. The excavations may
then be partly inundated. This risk is fully accepted by the developer and will not have
any impact outside the quarry.
23
DABGeot/11093/Final
5.3.2
(iv)
Discharges of treated water from the quarry will be controlled at or below greenfield
rates and consequently there will be no increased risk of downstream flooding.
(v)
The land use and drainage of the restored site (Dwg. No. R15/04) are such that the longterm runoff characteristics can be maintained at not greater than greenfield rates.
Additional attenuation will be provided by the creation of wetland areas in the north,
western and southern parts of the site.
(vi)
There are no proposals for flood defences or mitigation measures that might increase
flood risk elsewhere.
Attenuation Storage Volumes
The proposed quarry workings have been designed so as to minimize the area of disturbance at
each stage of its development. The exhausted workings will be backfilled and restored to reestablish the present landform and greenfield runoff rates. The drainage water from the restored
area will be directed into the excavations, but as it is extended, the flow paths will be extended to
supply wetland areas along the northern perimeter and in the western part of the site. Some of the
water will be discharged at point D1 to alleviate the localized flooding problem shown on Figure
6 (see Section 5.3.3). The discharges will represent normal agricultural drainage only and not
trade effluent. Surface runoff and groundwater that flows or is pumped from the working areas
will be directed through water treatment areas and will be discharged, subject to the consent of
the Environment Agency, into the unnamed tributary of Hog Dyke along the south-eastern
perimeter of the site.
The volume of storage required to attenuate the discharge of water from the disturbed areas of the
site has been determined using a lumped input-storage-output model as described in the CIRIA
SUDS Manual (CIRIA, 2007). The site lies in two catchment areas (Figure 5) and the highest
rainfall intensities derived using the Flood Estimation Handbook CD-ROM were used in the
calculations. Storm durations of up to 380 hours were considered with return periods of 1, 10, 20,
30, 50, 100 and 200 years.
The area of disturbance was determined for each stage of the development shown on the
Indicative Phasing Plans (Dwg. No. R15/05), together with an estimate of that created during the
formation of the boxcut (Phase 1). A factor of 0.85 has been applied to all areas of bare earth,
including newly constructed soil storage mounds, to calculate the equivalent impermeable area.
This may well prove to be a conservative estimate as the infiltration could well be much greater,
especially where unsaturated bedrock strata are exposed. The restored boxcut area was assumed
to have the same runoff characteristics as the existing arable land and a factor of 0.35 was applied
based on the catchment characteristics given in Table 3. Details of the calculations are provided
in Table 15.
24
DABGeot/11093/Final
The minimum area of disturbance at any stage during the quarry development will be 13.5
hectares. The water from this area will be drained and treated and then discharged to the south of
the quarry at a greenfield rate of 2.4 x 13.5 = 32 l/s (i.e. QBAR x area rounded down from 32.4
l/s). This will be the discharge flow rate into the unnamed tributary of Hog Dyke for which
consent will be sought from the Environment Agency. It will apply for the entire duration of the
quarry development and for all storm events.

A conservative estimate of the groundwater inflow is provided in Table 14. The volume of
groundwater was determined for the lumped input-storage-output model using the inflow rate for
Ro = re + 50m (i.e. the highest value) for each of the development stages considered. The rainfall
values were also increased by a factor of 10% to account for the likely effects of climate change
and in accordance with the recommendations made in Table 5 of the Technical Guidance to the
National Planning Policy Framework (Department for Communities and Local Government,
2012b). This assumes that the development will commence in 2012 or 2013. It is expected that
greenfield runoff rate will also increase, but a corrected value has not been used in the
calculations. The spreadsheet calculations are presented in Appendix H and a summary is given
in Table 16.

By far the majority of the required storage will be provided in the quarry excavations, but
capacity will also be created in the areas that have been stripped of soils as these will be bounded
by shallow excavation slopes. There will be significant retention in the water treatment lagoons
and drainage channels. Partial flooding of the mineral workings during times of inclement
weather is relatively commonplace and the risk is fully accepted by the developer.
5.3.3
Flooding of Station Road
It has been reported that Station Road occasionally floods at a point adjacent to the cemetery as
shown on Figure 6. It would appear that the drainage channel that extends along the southwestern perimeter of the cemetery presently discharges directly onto the road because of
blockages in the roadside ditch. An attempt has been made to attenuate the discharge flow by
constructing two storage lagoons at the location shown on Figure 6 (Photograph P6), one of
which is unlined and does not appear to retain water. It is proposed to divert the majority of the
surface flow from the application site by creating a wetland area in its northern part and diverting
the water along a more westerly route. This will then flow through the 150mm diameter drain that
extends beneath Station Road and into the lake that lies beyond. The drain will require further
inspection and remedial work.
5.3.4
Surface Water Abstractions
There are no licensed or unlicensed surface water abstractions within at least 1km of the site. The
proposed excavations also lie some distance from the River Nene, Hog Dyke and the flooded
mineral workings that now form protected areas. There will be changes in the pattern of surface
flow during the development, but the supply of water will be compensated by discharges into the
unnamed tributary of Hog Dyke along the south-eastern perimeter of the site.
5.3.5
The discharge of treated water from the site will require the consent of the Environment Agency
in the form of an environmental permit. The Agency will not only determine the discharge flow
rate to ensure that there will be no increased risk of downstream flooding, but also the quality of
the water. This will ensure that there will be no adverse effect on the nature conservation sites
into which Hog Dyke and its tributaries flow.
It is anticipated that the principal contaminant in the untreated water will be suspended solids and
that this can be suitably remediated by simple settlement. The majority will be retained in
temporary sumps formed within the excavations. The water treatment facilities will be regularly
inspected in accordance with the Quarries Regulations (1999). This will ensure that immediate
action is taken to maintain their stability, security and efficient operation. If it is required to use
flocculants, their use and dosage rate will be first agreed with the Agency. The operator will have
in place emergency measures to deal with any spillages (e.g. the deployment of absorbent mats
and booms). Fuel oil storage areas will be adequately bunded in accordance with Control of
Pollution (Oil Storage) (England) Regulations 2001 to protect both surface and groundwater.

SUMMARY
6.1
Mick George Ltd. proposes to develop a limestone quarry on land at Ringstead Grange Farm. The
exhausted workings will be backfilled with overburden, quarry discard and imported inert fill
materials, subject to the approval of the Environment Agency. The excavations will extend in
depth to a maximum of about 12m below ground level.
6.2
The proposed development will not have an adverse effect on surface water resources. There are
no licensed or unlicensed surface water abstractions within at least 1km of the site. Consent will
be sought from the Environment Agency to discharge treated water from the quarry during its
operation. It will determine the quality of the water and this will ensure that there is no adverse
impact on the receiving watercourses. It can therefore be concluded that there will be no adverse
effect on the areas of nature conservation in the Nene valley. The flows will be maintained at or
below greenfield rates and consequently there will be no increased risk of downstream flooding.
Storm flows will be attenuated by providing adequate storage during the operation of the site,
principally within the excavations. Partial flooding of the excavations during periods of
prolonged inclement weather is relatively commonplace in the quarrying industry and is fully
accepted by the operator.
6.3
The existing landform will be largely replicated as part of the proposed restoration scheme with
the majority taking the form of agricultural land. Wetland areas will be created to attenuate
surface flow. The northern part of the site will be drained towards the north, as is presently the
case, using the existing or a newly created agricultural drainage system. Greenfield runoff rates
will be restored throughout the site.
6.4
There will be no adverse impact on groundwater resources. There are no licensed or unlicensed
groundwater abstractions within at least 1km of the site. It is expected that very little groundwater
will be encountered in the excavations and consequently any drawdown will be very limited in
extent. The effect of any drawdown will be limited in area underlain by the Blisworth Limestone
Formation. By far the majority of the water that will be drawn from the quarry workings will be
surface runoff. The development will not increase the potential for swelling and shrinkage of the
clays and mudstones underlying Ringstead village or any other buildings around the site. The
farmstead at Top Lodge is unoccupied and derelict.
6.5
There are no known waste handling or treatment sites, or waste transfer stations within at least
1km of the proposed quarry extension that might otherwise represent potential sources of
groundwater contamination. The mineral excavations will be backfilled with material that will not
have an adverse impact on groundwater quality. The restoration drainage scheme will be
designed to cater for the settlement that will occur in the fill and the likely effects of climate
change.

Introduction
The Environment Act 1995 has made site sensitivity a key issue, as the legislation pays as much attention to the pathways by which
contamination could spread, and to the vulnerable targets of contamination, as it does the potential sources of contamination.
For this reason, Landmark's Site Sensitivity maps and Datasheet(s) place great emphasis on statutory data provided by the Environment
Agency and the Scottish Environment Protection Agency; it also incorporates data from Natural England (and the Scottish and Welsh
equivalents) and Local Authorities; and highlights hydrogeological features required by environmental and geotechnical consultants. It does not
include any information concerning past uses of land. The datasheet is produced by querying the Landmark database to a distance defined by
the client from a site boundary provided by the client.
In the attached datasheet the National Grid References (NGRs) are rounded to the nearest 10m in accordance with Landmark's agreements
with a number of Data Suppliers.

Index Map
For ease of identification, your site and buffer have been split into Slices,
Segments and Quadrants. These are illustrated on the Index Map opposite
and explained further below.
Slice
Each slice represents a 1:10,000 plot area (2.7km x 2.7km) for your site and
buffer. A large site and buffer may be made up of several slices (represented
by a red outline), that are referenced by letters of the alphabet, starting from
the bottom left corner of the slice "grid". This grid does not relate to National
Grid lines but is designed to give best fit over the site and buffer.
Segment
A segment represents a 1:2,500 plot area. Segments that have plot files
associated with them are shown in dark green, others in light blue. These are
numbered from the bottom left hand corner within each slice.
Quadrant
A quadrant is a quarter of a segment. These are labelled as NW, NE, SW,
SE and are referenced in the datasheet to allow features to be quickly located
on plots. Therefore a feature that has a quadrant reference of A7NW will be
in Slice A, Segment 7 and the NW Quadrant.

Dear Sir/Madam,
I am acting on behalf of Mick George Ltd. This company proposes to
develop a new quarry on land to the south of Ringstead Grange Farm. In
order to assess the possible impact of this development on surface and
groundwaters, I should be grateful if you could provide details of any
private water supplies within the area that extends up to 1km from its
boundary (e.g. location, abstractor's name, volume and use. I appreciate
that you may not be able to supply all of this information for reasons
of confidentiality.) The attached plan shows the site boundary and the
corresponding search area.
Yours faithfully,

Dear Sir
Proposals for scope and content of an application for a proposed limestone
quarry including extraction of clay and the deposit of inert waste for
restoration purposes
Ringstead Grange Ringstead
Thank you for your Environmental Impact Assessment (EIA) Scoping consultation,
which was received on 17 October 2011.
We have reviewed the scoping report submitted and our technical comments
detailing the information we consider should be provided in the Environmental
Statement (ES) are provided below.
Technical comments and advice
Hydrology and Hydrogeology
Sections 17 and 18 of the Scoping Opinion acknowledges that the hydrology and
hydrogeology of the site needs to be investigated to provide baseline conditions and
identify any water features which should be provided in a Flood Risk Assessment
(FRA).
From the information provided we can confirm that the site is greater than 1.0 ha and
lies within Flood Zones 1 (low probability of river and sea flooding as defined in
Annex D Planning Policy Statement 25 ‘Development and Flood Risk’ (PPS25)).
In order to fully assess the issue of flood risk, a fully compliant PPS 25 - Annex E
FRA must be undertaken and submitted with any planning application, which
considers and quantifies the different types of flooding as well as addressing the
surface water drainage for the development. Please note the FRA should address
the various phases of development (from mineral extraction through to
restoration). The FRA should form part of the EIA or be submitted as a standalone

document.
General FRA comments
The FRA must consider and quantify the different types of flooding to demonstrate
that flood risk is not increased by the proposed development and where possible,
reduced. Surface water run-off issues are a key factor for consideration. Any FRA
must demonstrate that surface water run-off can be managed for both, construction
and restoration and that the proposed surface water drainage system can cope with
1 in 100 probability plus climate change rainfall event without increasing flood risk to
the site, surrounding area and third parties.
The FRA must also demonstrate that construction and post development run-off
does not exceed pre-development run-off. Within the FRA, surface water run-off
rates for the existing and developed site for the 1 in 1 probability rainfall event, the 1
in 30 probability rainfall event and the 1 in 100 probability rainfall event and the
attenuation volumes required including an allowance for climate change should be
stated. In addition, any FRA must confirm whether the site run-off will be restricted
to the Qbar rate for all events or the Q1 for the 1 in 1 probability rainfall event, Q30
for the 1 in 30 probability rainfall event and Q100 for the 1 in 100 probability rainfall
event using a complex control.
Any attenuation required should be provided in line with the requirements of PPS25
and Preliminary Rainfall Runoff Management for New Development Revision D. The
drainage scheme proposed should provide a sustainable drainage strategy to
include SUDS elements with attenuation. The maintenance and/or adoption
proposals for every element of the surface water drainage system proposed on the
site should be considered for the lifetime of the development and the residual risk of
flooding addressed.
The FRA should also consider the possibility that the surface water system may fail /
become blocked. Overland floodwater flood water should be routed away from
vulnerable areas. For acceptable depths and rates of flow, please refer to
Environment Agency and Defra document FD2320/TR2 “Flood Risk Assessment
Guidance for New Development Phase 2”. Further consideration should be given to
safe access and egress for emergency services when site is flooded.
Environmental permitting
The restoration by inert landfilling element of development associated with this
development will require an Environmental Permit under the Environmental
Permitting Regulations 2010, from the Environment Agency, unless an exemption
applies. The Applicant is advised to contact the Environment Agency on 08708 506
506 for further advice and to discuss the issues likely to be raised. You should be
aware that the permit may not be granted. Additional ‘Environmental Permitting
Guidance’ can be accessed via our main website ( http://www.environmentagency.gov.uk ).
We ask that our Pollution Prevention Guidelines, are considered. These guidance
notes are available to download from:
http://www.environment-agency.gov.uk/business/topics/pollution/39083.aspx
The comments we set out above are without prejudice to future decisions we make
regarding any applications subsequently made to us for our permits or consents for
operations at the site.

Introduction
The Environment Act 1995 has made site sensitivity a key issue, as the legislation pays as much attention to the pathways by which contamination could spread, and to the
vulnerable targets of contamination, as it does the potential sources of contamination.
For this reason, Landmark's Site Sensitivity maps and Datasheet(s) place great emphasis on statutory data provided by the Environment Agency and the Scottish
Environment Protection Agency; it also incorporates data from Natural England (and the Scottish and Welsh equivalents) and Local Authorities; and highlights
hydrogeological features required by environmental and geotechnical consultants. It does not include any information concerning past uses of land. The datasheet is
produced by querying the Landmark database to a distance defined by the client from a site boundary provided by the client.
In the attached datasheet the National Grid References (NGRs) are rounded to the nearest 10m in accordance with Landmark's agreements with a number of Data
Suppliers.

Report Section and Details
Summary
Page Number
-
The Summary section provides an overview of the data contained within the report, detailing the number of data set
features or the existence of a data set in relation to the buffer selected.
For ease of reference, the report is broken down into 4 sections of data; Mining and Natural Cavities Data, Historical
Land Use Information (1:2,500), Historical Land Use Information (1:10,000) and Ground Stability Data (1:50,000).
Mining and Natural Cavities Data
1
The Mining and Natural Cavities Data section features data sets related to the existence of mining areas and their
potential hazards; and details of naturally formed cavities.
Data sets within this section are not plotted, with the exception of BGS Recorded Mineral Sites and Potential Mining
Areas which feature on the Historical Land Use Information (1:10,000) map.
Historical Land Use Information (1:2,500)
2
The Historical Land Use Information (1:2,500) section contains data captured from analysis carried out by Landmark of
1:1,250 and 1:2,500 scale historical Ordnance Survey mapping, identifying areas where, historically, the land uses were
potentially contaminative.
For the purpose of this Envirocheck module, only historical data relating to mining and ground stability has been
included and plotted on the corresponding Historical Land Use Information (1:2,500) map. This section also includes the
Subterranean Features data set, which details various man-made and man-used underground spaces obtained from the
Subterranea Britannica society.
3
The Historical Land Use (1:10,000) section covers data captured from the systematic analysis carried out by Landmark
of 1:10, 560 and 1:10,000 scale historical Ordnance Survey mapping dating back to the mid-19th century, identifying
potentially contaminative past industrial land uses.
For the purpose of this Envirocheck module, only data relating to mining and ground stability has been included and
plotted on the accompanying Historical Land Use Information (1:10,000) map.
Ground Stability Data (1:50,000)
4
The Ground Stability (1:50,000) section includes the BGS Geosure data suite, reporting features to 250m and plotted
onto 3 separate maps. Also reported is brine subsidence, brine mining and salt mining data sets, of which Brine
Pumping and Salt Mining Related Features are plotted, and subsidence insurance claims and insurance investigations
data, which is not plotted.
Motion Map Data (1:2,500)
-
The Motion Map Data (1:2,500) section contains data which is plotted to indicate long-term stability trends from analysis
of satellite radar data.

Flood Risk Assessment
DABGeot/11093/Final
FLOOD RISK ASSESSMENT
The following flood risk assessment has been carried out in accordance with the National Planning Policy
Framework (NPPF) (Department for Communities and Local Government, 2012a) using the Technical
Guidance (Department for Communities and Local Government, 2012b), but is set out in the order that is
shown on the proforma in Appendix B of the revised guidance document for the former PPS25:
‘Development and Flood Risk’ (Department for Communities and Local Government, 2009) with
identical section headings and numbering where possible.
1. DEVELOPMENT DESCRIPTION AND LOCATION
1a. Type of Development and Location
It is proposed to develop a quarry on arable land at Ringstead Grange Farm and to restore the site by
backfilling the mineral workings with overburden, quarry discard and imported inert material. The site is
located about 1.5km south-west of Ringstead and 2km north-west of Raunds in an area administered by
East Northamptonshire and Northamptonshire County Councils (Figure 1). The Grid Reference for the
centre of the site has been taken as 498050 273900 (1/50,000 scale Ordnance Survey Map Sheet 141
Kettering, Corby & Surrounding Area).
1b. Vulnerability
Table 2 of the Technical Guidance to the NPPF classifies mineral workings as, ‘less vulnerable’,
development. Landfill sites are considered to be, ‘more vulnerable’.
1c. Local Development Documents
The site at Ringstead Grange is identified on Northamptonshire County Council’s Minerals and Waste
Development Framework, Location of Mineral Development Plan (Site MA9) which was published in
March 2011. A Catchment Flood Management Plan (Environment Agency, 2009) and Strategic Flood
Risk Assessment (Faber Maunsell/AECOM, 2006 and URS Scott Wilson, 2011) have been prepared for
the area.
1d. Sequential/Exception Test
With regard to the Sequential Test, the proposed development is shown on the Environment Agency
Flood Map (Appendix A) to be in Flood Zone 1 and cannot therefore be moved to an area of lower flood
risk. Mineral workings, other than those for sand and gravel, are classified as, ‘less vulnerable’, in terms
of their flood risk, whilst landfill sites are considered to be, ‘more vulnerable’. Table 3 of the Technical
guidance to the NPPF indicates that an exception test is not required for less or more vulnerable sites in
Flood Zone 1.
1e. Risk of Flooding to Occupants during and after Restoration
There will be no dwellings on the site during its operation or following its restoration. The health and
safety of quarry operatives will be adequately assessed and monitored in line with the existing safety
legislation: principally the Quarries Regulations, 1999. Surface and groundwaters will be properly
managed. Any flooding of the quarry floor will not pose a risk to members of the public or other
properties. The quarry will be restored to agriculture, together with areas of ecological interest which will
partly comprise wetland features. The existing landform will be largely replicated.

DABGeot/11093/Final
2. DEFINITION OF FLOOD HAZARD
2a. Sources of Flooding
The site is not at risk of flooding from rivers or, ‘blue-line’, watercourses. The proposed working area,
which is shown on the Working Scheme Plan (Dwg. No. R15/03), lies about 0.5km due east of the River
Nene. The difference in elevation between the site and the river is at least 23m. An unnamed tributary of
Hog Dyke flows along the south-eastern boundary, but this occupies a wooded valley whose depth well
exceeds any likely flood levels. There are no records of any historic fluvial flooding of the site.
The Ordnance Survey topographic plans indicate that surface gradients are generally directed away from
the site boundary. Agricultural drainage is present on the site and although a number of drainage ditches
can be observed detailed plans are not available. Areas of standing water may well form on the site during
prolonged periods of inclement weather when the drainage capacity is exceeded, but these are not
permanent. Flooding may occur if the drainage channels in the proposed development prove inadequate or
if pumping operations are suspended, but this will be confined within the mineral workings. The effect
will be minor and the risk is fully accepted by the developer. The mineral workings will be backfilled and
the existing landform replicated. An agricultural drainage system will be installed and greenfield runoff
rates will be re-established so that the risk of pluvial flooding both within and downstream of the site will
be no greater than at present.
It is anticipated that some groundwater will be encountered during the operation of the site (see Section 4
of the main report). The quarry workings may flood if there is a temporary suspension in pumping
operations, but the effects will be minor and temporary in nature and the risk is again fully accepted by
the developer.
There are no sewers on the site and there are no plans to use sewers for drainage purposes.
Rainfall levels may rise during the working life of the site and post-restoration as a consequence of
climate change. Discharge flows will be controlled at greenfield rates, but these are also expected to
increase. The risk of downstream flooding should therefore be no greater post-restoration. Additional
retention will be provided by creating the wetland areas along the north-western, western and southeastern margins of the site. These are shown on the Concept Restoration Scheme Plan (Dwg. No. R15/04).
2b. How Flooding Could Occur
It is possible that during periods of prolonged inclement weather, the proposed excavations may become
partly flooded as a consequence of surface runoff. Flooding may also occur as a consequence of
groundwater inflow. This will depend on the capacity of the drainage channels that will be formed in the
workings and the capacity and reliability of any pumps that may be deployed. This operational hazard is
relatively commonplace in quarrying and is fully accepted by the developer. It will not affect any
properties lying outside the quarry.
2c. Existing Surface Drainage
The proposed quarry site is currently used for agricultural purposes. An agricultural drainage system is
thought to be in place, but detailed plans are not available.

DABGeot/11093/Final
3. PROBABILITY
3a. Flood zones
Extracts from the Environment Agency’s Flood Map are provided in Appendix A. The map shows that
the extension site is located in Flood Zone 1 (i.e. in an area that has less than 0.1% AEP of flooding).
3b. Strategic Flood Risk Assessment
A Strategic Flood Risk Assessment has been prepared for the area administered by East Northamptonshire
Council (Faber Maunsell, 2006 & URS Scott Wilson, 2011). This confirms that the proposed quarry site
lies in Flood Zone 1.
3c. Probability of Flooding
The principle risk of flooding relates to the capacity of the drainage system during the operation of the
quarry and its ability to conduct water at an adequate rate. The drainage system will therefore be designed
with this in mind. However, the consequences of partial inundation of the mineral workings are minor and
are accepted by the developer.
The design of the restoration drainage system will be in line with the usual standards for agricultural
restoration. An adequate level of protection will be provided against flooding. Putting aside any changes
that might arise due to climate change, the risk of flooding on the site should remain at pre-development
levels because the existing landform will be replicated.
3d. Runoff
It is proposed to discharge water from the quarry workings into an unnamed tributary of Hog Dyke
following its treatment (see Section 5.1 of the main report). The discharge flows will be at or below
greenfield rates. This watercourse is located along the south-eastern perimeter of the site and will continue
to form an important drainage path post-restoration (Concept Restoration Scheme Plan, Dwg. No.
R15/04).
4. CLIMATE CHANGE
Surface runoff from the extension site would be expected to increase as a consequence of the greater
intensities of rainfall that might occur due to climate change, unless it can infiltrate the exposed bedrock.
The design of the site drainage system should therefore cater for an increase in rainfall intensity of 10%
during quarrying and 10% for the post-restoration period. This assumes that development will commence
in 2012 and will be completed within an 11 to 15 year timeframe. These increases are in line with the
recommendations given in the Technical guidance to the NPPF (Table 5). Greenfield runoff rates might
be expected to increase similarly. Predicted increases in river flows will not affect the site because of its
location.
G3
DABGeot/11093/Final
5. DETAILED DEVELOPMENT PROPOSALS
An account of the proposed development is provided in the Environmental Statement and Section 1.4 of
the main report. Details are shown on the Working Scheme Plan (Dwg. No. R15/03) and the Indicative
Phasing Plans (Dwg. No. R15/05). The layout of the site is governed by the geology of the area, in
particular the location of the mineral reserves.
None of the areas most sensitive to flooding, such as the site offices, is considered to be at risk because
the drainage system will be designed to ensure that major flooding does not occur. Mobile plant will be
used to excavate and process the limestone and deposit the fill materials and can be quickly evacuated
from any areas that could become flooded. Fuel oils will be stored in accordance with the Control of
Pollution (Oil Storage) (England) Regulations 2001.
6. FLOOD RISK MANAGEMENT
The site is not in a flood risk area and the proposed working areas are considered to be secure because of
their location. No protective measures are required as there are no likely sources of external flooding. The
risk of flooding is limited to surface runoff and groundwater within the development area itself. Climate
change may increase this risk during the operation of the quarry, but it will not affect properties lying
outside the site boundary.
7. OFF-SITE IMPACTS
7a. Impact of Flood Prevention Measures
The proposed quarry site is not located in a floodplain so there will be no loss of flood storage capacity or
conveyance. There will be no works carried out in watercourses that might otherwise affect flood flows.
7b. Runoff
During the Operation of the Quarry
The rate and volume of surface runoff will increase after the stripping of soils and the removal of
overburden. However, all such runoff will be contained within the quarry by the excavated slopes and cutoff ditches and some will be able to infiltrate the exposed bedrock.
Upon Completion of the Quarry
The developer is aware of the Environment Agency’s intention to prevent increased runoff from
development sites, even in Flood Zone 1. The site will be restored to agriculture with areas of ecological
interest, some of which will comprise wetland features. The present landform will be replicated and
greenfield runoff rates will be re-established with some additional storage capacity along the northwestern, western and south-eastern margins of the site. There will be no increased risk of downstream
flooding.
G4
DABGeot/11093/Final
8. RESIDUAL RISKS
8a. Residual Flood Related Risks
The site lies in Flood Zone 1 and is elevated above the natural watercourses in the area. The residual risk
of flooding from these sources (i.e. in the event of a flood of greater than 0.1% AEP) is negligible. The
excavations may become partly flooded should a severe rainstorm occur and the drainage system proves
inadequate. This would not present a risk to site personnel or mobile plant. Partial flooding of quarry
excavations is relatively commonplace and this is fully accepted by the operator. Post-restoration, such
severe runoff may exceed the capacity of the drainage system, although this will be designed to take into
account the predicted effects of climate change. Some parts of the site could become water laden, as may
reflect the current situation, but only on a temporary basis. The existing landform will be replicated and
additional attenuation will be provided by creating wetland areas.
8b. Management of Residual Risks
Residual risks of flooding will be managed by the developer and site operator, Mick George Ltd.
