and in the south-west area of the site they are locally reversed, with
westerly directions indicated on the maps.
13.12 Three geological faults are shown in the study area. All three trend in a
north-west/south-east direction. The fault that passes through the southwest
corner is the most significant structure with an estimated
displacement of 100m down to the north-east. The fault in the north has a
south-west throw of less than 3m. The downthrow sides of faults are
shown on Drawing HJB/681/PA17 (Sheet 1).
13.13 No outcropping coal seams are present within the site boundary although
there are coal seams encountered deeper within the sequence.
13.14 No geotechnical information is available for the study area.
13.15 Should the micro-siting of turbines be considered necessary due to the
nature of the site there would be no implications upon the geology of the
locality and the findings of this study will still stand true.
HYDROGEOLOGY AND HYDROLOGY
13.16 The Pennine Middle Coal Measures formation beneath the majority of the
site is classified as a „Minor Aquifer‟, with low soil leaching potential. Whilst
the Mexborough Rock at outcrop in the extreme south of the site is
classified as a „Minor Aquifer‟ with high soil leaching potential.
13.17 The site is located entirely within the catchment of Ulley Brook which
drains westwards as two separate streams converging at Ulley Reservoir,
approximately 1km west of the western site boundary. The local
hydrological regime is shown on Drawing 049/04/01 in the FRA report
(Appendix 9). The drainage areas of each branch of the brook are shown
on Drawing 049/04/01 together with the location of any relevant control
structures.
13.18 It is apparent that the majority of the proposed development site currently
drains to the southern branch of the Ulley Brook whilst the northern third of
the site drains to the northern branch of the brook. Surface water drainage
characteristics in each sub-catchment are summarised within the FRA
report (Appendix 9).
13.19 The site is located in Flood Zone 1, outside the limit of high or moderate
fluvial flood risk. Environment Agency flood zone maps indicate that the
site is not at risk of fluvial flooding from the Ulley Brook in response to
either the 1 in 100 year or 1 in 1000 year flood event.
MINING AND QUARRYING
13.20 Historical plans and geological maps indicate no disused quarries within
the study area.
